Description: A Mine-Disposal Assembly and the Way of Its Operating BACKGROUND OF THE INVENTION Field of the Invention The presented invention relates to a mine-disposal assembly for the removal of explosives from the mined territories and the way of its operating. Description of the Related Art The machines for the removal of explosives from the mined territories known so far are constructed in such a way that the activating equipment, which is mostly operated from the cabin of a conveyance or from the other cabin provided for this purpose, is as a rule replaceably or removably attached directly to a tractive conveyance on track or wheeled bogies from its rear or front side. For the service staffs of both the machine and the activating equipment, which consist of at least one person, it is dangerous to be present close to the source of explosion while operating the machine, when mines are digged out by hammers of bumping flails, activated by their hits, or unsufficiently removed and may explode after passage of a track or wheel of the machine. From the reason of minimizing the risk for the service staffs the operational cabines are placed as far as possible from the sources of explosions and are equipped with a safety armour; the activating equipment is separated from the cabins with covers as well, however, the risk of an injury or killing the service staffs still persists, which is the main drawback of these machines. Other drawbacks are heavy weight and constructional bulkiness of the machines which result in their low exploitation on great gradient hillslopes, in narrow slots and at similar places. SUMMARY OF THE INVENTION The drawbacks mentioned above are to a large extent removed by the mine-disposal assembly composed of a conveyance and a mine-disposal unit, and also by the way of its operating according to the presented invention which is based on the fact that the conveyance- independent mine-disposal unit consists of an operating workplace with a remote controller and a mobile mine-disposal machine with a receiver of radiowaves mechanically separated from the unit. To the bogie of the hydraulic mine-disposal machine the system of at least two first and at least two second mobile wheels or mobile tracks is fixed. The first mobile wheels are through the first hydraulic engine and the second mobile wheels are through the second hydraulic engine connected with hydrogenerators . On at least one manipulating arm of the mine-disposal machine the activating equipment is attached by means of a swinging clamp. At the beginning of at least one manipulating arm the frame joint is placed swingingly towards the frame of the mine-disposal machine and at its end the arm joint is placed swingingly towards the arm plate of the swinging clamp. At both edges of the clamping plate, which is firmly connected to the arm of the activating equipment, the activating joint is placed swingingly towards the arm plate of the swinging clamp. The arm of the activating equipment is interconnected with the activating frame through the rotary hanger. On the frame of the activating equipment a protective shield is attached and on the side bearers of this frame guide skids are fixed from the bottom side. At the front part of the activating equipment the bumping flails are placed on the rotary axle with an activating hydraulic engine. The upper part of the protective shield is formed by a shaped deflector where the angle of its gradient is defined by the line passing through the place of an explosion of an activated mine, touching the deflector and passing by the protective shield of the mine-disposal machine. The protective shield under the deflector is formed by a bumper the height of which equals at least the height of the swinging clamp and at the most two thirds of the diameter size of the revolving bumping flails, while the α angle of the bumper gradient equals at the most 80°. The activating hydraulic engine of the activating equipment is connected to the rotary axle with fixed system of the bumping flails either directly or through a supplementary transmission. The way of operating the presented mine-disposal assembly is based on the fact that an operator at the protected service workplace manipulates the operating elements of the remote controller from which the radio signal is transmitted by the radiowaves and/or by an optical cable to a distant receiver placed in the mobile mine-disposal machine. After processing this radio signal the particular electrohydraulic systems which control hydrogenerators through the hydraulic signals are controlled through the electrical signals, according to the commands of an operator. Consequently, these will start the first hydraulic engine with the first mobile wheels or tracks, the second hydraulic engine with the second mobile wheels or tracks and the activating hydraulic engine with the rotary axle and bumping flails.

DESCRIPTION OF THE PREFERRED EMBODIMENT The mine-disposal assembly is as an example shown in Fig. 1. It consists of a conveyance 1 which is a lorry on the bed of which the cabin of the service workplace 2 . with a remote controller . 21. is installed and also the mine-disposal machine _3 with the receiver 3_1 whereto the activating equipment 4_ is connected through the swinging clamp 5 . The mine-disposal machine 3 . itself (see Fig. 2) consists of the bogie whereon the first and the second mobile wheels 3 . 3 . , 3_4 controlled by the hydraulic engines 35 , 36 (not shown in Fig. 2) are placed from both left and right side. The bogie is firmly attached to the frame whereon the machine cabin (not shown in Fig. 2) with the protective shield 3 . 9 is placed. In the upper part the doubled manipulating arm 37 is connected to the frame of the mine-disposal machine 3 . through the swinging frame joints 3_8 along both its sides and in the lower part the activating equipment 4_ is fixed thereto through the swinging clamp !5. The connection of this activating equipment 4 . (see also Fig. 4) is realized in such a way that in the lower part the arm plate _5_2 is interconnected swingingly with the doubled manipulating arm 3J7 through the arm joint 5_1 and in the upper part it is swingingly interconnected with the clamping plate 5_4 through the activating joint 53. To the arm 5_5 of the activating equipment 4 . , which is firmly connected with the clamping plate 5_4, the rotary hanger 55 is attached. On the activating frame 4_6 the protective shield 6 and from the bottom side the guide skids 4_5 are fixed through the side bearers 42 from both sides. The activating hydraulic engine 4JL of the activating equipment 4_, installed on the rotary axle 4 . 3 with the bumping flails 4_4, is connected to the hydraulic system (not shown in Fig. 2 and Fig. 4) of the mine-disposal machine 3 . through a hydraulic hose. From the simplified scheme (see Fig. 3) of motion freedom of the particular elements it is obvious that the frame joint 3jB / the arm joint 5JL and the activating joint 53 are freely movable in the vertical direction and the rotary hanger 5_6 is freely movable in the horizontal direction which provides thorough copying of the terrain in both its longitudinal and transversal planes. The protective shield 6 . of the activating equipment 4_ is constructed of the shaped metal plate (see Fig. 5). Its upper part is formed with the deflector 6_1 bent under the angle tilt of ' the line coming out of the point in the place of an activated mine 47. The part of the plate under the deflector 6 is formed as a bumper 6_2 with the angle tilt ct which is equal to 70°. Operating the mine-disposal assembly according to the presented invention is clear from the simplified scheme (see Fig. 6). The operator in the cabin of the workplace 2 manipulates the operating elements of the remote controller 2 also consisting of the control processor, radiomodem, source (not shown in the drawings) and the transmitting antenna 211 (see Fig. 1). The radio signal 213 is emitted by the transmitting antenna 211 and transmitted through the radiowaves into the receiver 31 , placed in the mobile mine-disposal machine 3 . , through its receiving antenna 311. The radio signal 213 is processed in the receiver 3_1 through its radiomodem and control processor (not shown in the drawings) and the corresponding commands are sent into the electrohydraulic systems 313 in the form of the electric signal 312. The hydraulic signal 314 controls the corresponding hydrogenerators 32 . and consequently the hydraulic engines 35 , 36 and 4 . 1. The first hydraulic engine 3 . 5 then sets the first mobile wheels 22, spinning, the second hydraulic engine 3 . 6 sets the second mobile wheels 2 _ spinning and the activating hydraulic engine 41 . sets the rotary axle 4J3 with the bumping flails . 44 . spinning. The mine-disposal assembly is transported to the mined area by the lorry 1 on the bed of which is the cabin of the service workplace 2 and two pieces of the activating equipment 4 . , one of them as a spare part. At the same time on the trailer carriage the mine-disposal machine 3_ is delivered whose first mobile wheels 3_3 and second mobile wheels 3_4 are manipulated by the operator in the way described above and the mine-disposal machine is backed on the ground. Through the swinging clamp 5 . the activating equipment 4 . is fixed to the doubled manipulating arm 3 . 7 and the mine-disposal assembly is ready to dispose mines. The mine-disposal of the area is performed in the way that the mine-disposal machine 3 . is placed at the beginning of the area , the rotary axle 4_3 with the bumping flails 4_4 is set spinning in the above mentioned way and the mine-disposal machine 2_ is set to motion by setting the first mobile wheels 3J3 and the second mobile wheels 2 spinning. The bumping flails 44 . dig or knock off the mined area , bump and thus activate the mines 4_7 which results in their removal from the mined area. After finishing the mine-disposal the mine-disposal machine 3_ and the activating equipment 4 . are placed on the conveyance and driven away from the place of the mine-disposal .
