The working body earthmovers
The invention relates to the field of earth-moving machines and can be used in the working bodies of draglines, excavators, bulldozers, loaders, with working bodies with replaceable teeth. The working body earthmovers contains cutting edge and mounted on it by means of fasteners teeth. On the cutting part of the working body longitudinal rails. Teeth, even relative to the left and right extreme of the teeth of the cutting part, installed in the guide with the possibility of a fixed displacement in the past. The guides are made along the cutting portion in the form of through slots for the installation and rigid fixation of even teeth. The edges of each groove equidistant from the fixed teeth and the length of the grooves is not less than half the distance between adjacent lateral surfaces of the two series set of teeth in their uniform arrangement on the cutting edge. On the lower and/or upper sides of the cutting part is installed limiters triangular cross section, one side of which is still connected with the cutting part and the second adjacent to the tooth, and the third coupled with the second made flush with the surface of the cutting part. Led the region of the earth-moving machines and can be used in the working bodies of draglines, excavators, bulldozers, loaders, and similar machines with working bodies with replaceable teeth.
Known working body of earth-moving machines, containing cutting edge with replaceable teeth, mounted in the guide (see S patent No. 262856, publ. 06.04.88, CL MCI E 02 F 3(40)).
The disadvantage of the working body is the inability to adjust the distance between the teeth, which affects the cutting conditions of the soil and the frequency of replacement teeth.
The basis of the invention is the task of reducing the effort of digging and ensuring uniformity of wear of the side surfaces of the teeth that will increase their service life.
The problem is solved in that in the known working body at its cutting part is made of longitudinal rails, with teeth, even relative to the left and right extreme of the teeth of the cutting part, installed in the longitudinal guides, with the possibility of a fixed displacement in the past. The guides are made along the cutting portion in the form of through slots for the installation and rigid fixation of even teeth, and the edges of each groove equidistant from the fixed teeth and the length of the grooves is not less than half the distance between adjacent side is lower and/or upper sides of the cutting part of the established limitations of the triangular cross-section, one side of which is still connected with the cutting part and the second adjacent to the tooth, and the third coupled with the second made flush with the surface of the cutting part.
Due to the possibility of changing the distance between the teeth is provided by reducing the effort of digging the ground as the cutting part of the working body earthmovers, and every tooth individually. At the same time this solution will allow revenuest teeth of the working body.
In Fig.1 shows a cutting part with a removable false teeth; Fig.2 shows the section a-a of Fig.1.
The working body earthmovers (see Fig.1) contains cutting edge 1 and installed it using fasteners 3 teeth 2. On the cutting part 1 working body longitudinal rails 4, and the teeth 2, even relative to the left and right extreme of the teeth of the cutting element, installed in the guide 4 with the possibility of a fixed displacement in the past. Rails 4 is performed along the cutting portion 1 in the form of through-groove (see Fig.2) for installation and rigid fixation of even teeth. The edges of each groove equidistant from the fixed teeth and the length of the grooves is not less than a half of the distance m is information on cutting part (see Fig.1). On the lower and/or upper sides of the cutting part 1 set the limiters 5 triangular cross section, one side of which is still connected with the cutting part 1, the second is adjacent to the tooth 2, and the third coupled with the second made flush with the surface of the cutting part 1.
The working body earthmovers works as follows.
The teeth 2, even relative to the left and right extreme of the teeth of the cutting part 1, are mounted in the guides, with the possibility of a fixed displacement in the past. They can navigate through the groove in which is rigidly fixed at a distance of determined by the type developed ground to ensure uniform wear of the side surfaces of the teeth 2. The edges of each groove equidistant from the fixed teeth and the length of the grooves is not less than half the distance between adjacent lateral surfaces of the two series set of teeth 2 in their uniform arrangement on the cutting part (see Fig.1). On the lower and/or upper sides of the cutting part 1 set the limiters 5 triangular cross-section, which prevents transverse movement of the tooth on the cutting part 1. One side of the boundary is Lana flush with the surface of the cutting part 1.
1. The working body earthmovers, containing the cutting part and installed it using fasteners teeth, characterized in that the cutting part of the working body longitudinal rails, with teeth, even relative to the left and right extreme of the teeth of the cutting part, installed in the guide with the possibility of a fixed displacement in the past.
2. The working body earthmovers under item 1, characterized in that the guides are made along the cutting portion in the form of through slots for the installation and rigid fixation of even teeth, and the edges of each groove equidistant from the fixed teeth and the length of the grooves is not less than half the distance between adjacent lateral surfaces of the two series set of teeth in their uniform arrangement on the cutting edge.
3. The working body of the earth-moving machine according to any one of p. 1 or 2, characterized in that the lower and/or upper sides of the cutting part is installed limiters triangular cross section, one side of which is still connected with the cutting part and the second adjacent to the tooth, and the third coupled with the second made Zapadni the
