Support-rotating device
The invention relates to the technical equipment harvesting machinery used for felling and bunching trees, and can be used in the forest industry.
Known rotation device including a tube mounted on U-shaped farm inserted into the tube of the rotary column, on which is mounted manipulator with its actuator, and the rotation mechanism of the manipulator in the horizontal plane (kussakin NF design and operation of the skidders: Textbook. Allowance for vocational schools. - M.: Forest industry, 1985. - 272 S., see s and RIS).
Known rotation device is applied, generally, to machines of small and medium capacity and a rotation angle in the horizontal plane less than 360°.
Closest to the invention is a rotation device comprising a support rotatable roller, lower stationary part which is rigidly fixed on the frame of the self-propelled chassis and is provided on the inner circumference of the ring gear, and the upper movable part of the hard-coded rotary platform on which to mount the manipulator and the mechanism of rotation of the platform with manipulator in the horizontal plane relative to the frame of the self-propelled chassis, including the engine and gearbox on the output shaft which is rigidly mounted ve the current gear, being in mesh with a ring gear fixed part (Circles B.C., Borman M.A., Ermolov VP, Queens, V.E., Popov BV Felling-bunching machine PL-19. - M.: Forest industry, 1982. - 288 S., see p.15 5, p.20 9, p.21 10 and pp.33 Fig.19).
The disadvantage of this turntable is that the leading gear and ring gear are spur gearing, which means that when the internal toothing is in engagement no more than two teeth and transmitted at high effort and dynamic loads is a bummer of teeth in mesh and the failure of the machine as a whole.
To eliminate this drawback in the support-rotating device comprising a support rotatable roller, lower stationary part which is rigidly fixed on the frame of the self-propelled chassis and is provided on the inner circumference of the ring gear, and the upper movable part of the hard-coded platform on which to mount the manipulator and the mechanism of rotation of the platform with manipulator in the horizontal plane relative to the frame of the self-propelled chassis, including the engine and gearbox on the output shaft which is rigidly mounted a leading gear that is in mesh with a ring gear fixed portion of the support, according to the invention on the output shaft of the gearbox installed faceplate on which the axes in the established additional gear driven by the pinion by means of a flexible connection, for example, a bushing roller chain and tsevochnyh sprockets, one of which is installed on the shaft of the pinion, and the other on the axes of additional gears, with additional gears are in mesh with a ring gear fixed portion of the support, and the faceplate is connected with the pivoting platform, and the faceplate is mounted device to adjust the tension sleeve roller chain, for example, in the form of mobile ignorant zavoznoy sprocket and an idler pinion and leading gear set so that between their axes is equal to the distance along the arc of a circle, in particular, angle 120°.
The proposed construction of a turntable allows you to have engaged a large number of teeth, which greatly increases the reliability and durability of the device.
1 shows a rotation device, the incision; figure 2 - is the same, the section a-a in figure 1 (rotary platform conventionally not shown).
Rotation device includes a support rotatable roller containing the lower stationary part 1, which is rigidly fixed on the frame of the self-propelled chassis (figure 1 conditionally self-propelled chassis frame not shown). The upper mobile part 2, which is rigidly set is established with representation from the rotary platform 3 with a handle (not shown) and the rotation mechanism 4 turntable 3 with the arm in a horizontal plane relative to the frame of the self-propelled chassis. The upper mobile part 2 is rotated relative to the lower fixed part 1 on the rolling elements 5, for example rollers. On the output shaft 6 of the turning mechanism 4, for example gear with the engine on the input shaft is rigidly mounted a leading gear 7, the teeth of which engages with the teeth of the ring gear 8, is made along the inner circumference of the lower fixed part 1. On the output shaft 6 is installed faceplate 9, in which the axes 10 and 11 installed additional gears 12 and 13. Axis 10 and 11 may be connected with a rotary platform 3 (see figure 1). On the output shaft 6 and the axes 10 and 11 rigidly mounted tsevochnye sprockets 14, 15, 16 to drive the rotation of the gears 12 and 13 with a flexible coupling, for example, a bushing-roller chain 17. Gears 12 and 13 are in engagement with the teeth of the ring gear 8. On the face plate 9 is installed ignorant zavodna sprocket 18, which by means of the axis 19 is able to move along the groove 20, is made in the faceplate 9.
The statement includes a rotation mechanism 4 turntable 3. When the output shaft 6 with the pinion 7 is forced to rotate around its vertical axis and the teeth of the pinion 7 obkatyvalisj serrated crown 8 of the fixed part 1 and the upper movable part 2 with turntable 3 b the children to turn in a horizontal plane on the rolling elements 5. Additional gears 12 and 13 are also in mesh with a ring gear 8, and since they are connected by sprockets 14, 15 and 16 and the stub-roller chain 17 with the drive shaft 6, also become the leading and the force of rotation is transmitted substantially through a larger number of teeth. To adjust the tension sleeve roller chain 17 on the faceplate 9 installed device 18.
In such a constructive implementation of a turntable in engagement at the same time there is a large number of teeth, which greatly increases the reliability and durability of the device, the efficiency of the machine as a whole.

FIELD: agriculture, physics.
SUBSTANCE: moisture content of the forest combustible materials (FCM) is determined by sounding the underlying surface in the SHF-range in the wave length allowing the electromagnetic radiation to pass through the FCM surface layer, forming the image matrix by means of a multi-beam antenna with the adjustable count digitisation in the scan band and the separate reception path in every beam, calculating the image matrix signal parameters, i.e. M1 making mathematical waiting, σ being mean square departure, Sp being the relief shape, S0 being the processed matrix geometrical area. It also includes separating the outlines on the image by the methods of spatial differentiation and FCM moisture content (W) inside the said outlines by the calibration function, i.e. W,%=Sp/S0·exp(M1/σ)·100%, where Sp is the image matrix signal relief area, S0 is the processed matrix geometrical area, M1 is the signal mathematical waiting, σ is the signal mean square departure.
EFFECT: fast determination of forest fire danger over vast territory.
