The invention provides a ripper beam of a bulldozer, wherein the ripper beam comprises a supporting tube 4 extending transversely and a plurality of racks connected to the supporting tube 4, each rack comprises two vertical plates 1 perpendicular to the supporting tube 4 and spaced from each other and a pin shaft 2 located between the two vertical plates 1, the vertical plates 1 are provided with insertion holes, and two ends of the pin shaft 2 are inserted into the insertion holes and welded to the vertical plates 1.
The tooth frame is composed of two main vertical plates 1 and a pin shaft 2 positioned between the two vertical plates 1, the two vertical plates 1 keep an interval, two ends of the pin shaft 2 are inserted into insertion holes in the vertical plates 1, the pin shaft 2 is connected with the vertical plates 1 in a welding mode, and the vertical plates 1 can be made of low-alloy high-strength steel.
The support tube 4 may support the rack, on which a rack described below may be mounted to loosen the soil by the rack.
In this scheme, replace original foundry goods rack through the rack that two risers 1 and round pin axle 2 welding are constituteed, simplified manufacturing process, the cost is reduced.
In addition, the ripper beam further includes a rack bar clamped between the two vertical plates 1 and extending downward. The rack extends downwards between the two vertical plates 1 and is clamped by the two vertical plates 1 to realize fixation. The racks extend out of the lower portions of the two vertical plates 1 and can be inserted into the ground, and soil loosening operation is achieved in the moving process.
Furthermore, the cross beam of the scarifier also comprises a connecting pin shaft which penetrates through the upper end of the rack and the two vertical plates 1. Two ends of the connecting pin shaft can be inserted into two vertical plates 1, such as holes which are not marked in fig. 2, the connecting pin shaft penetrates through the upper ends of the racks to limit the racks to move between the vertical plates 1, and the racks can be kept basically fixed relative to the vertical plates 1 by matching with the clamping effect of the vertical plates 1 on the racks.
In addition, a plurality of reinforcing ribs 3 are arranged between the two vertical plates 1 of each toothed rack, and the reinforcing ribs 3 are welded and connected to the two vertical plates 1. Referring to fig. 2, a plurality of reinforcing ribs 3 are further disposed between the two vertical plates 1, and the reinforcing ribs 3 are respectively welded to the surfaces of the two vertical plates 1 opposite to each other, so that the vertical plates 1 can be supported at more positions, and it is ensured that the two vertical plates 1 are more difficult to deform.
Further, the plurality of reinforcing beads 3 includes a main reinforcing bead extending downward from the insertion hole at the upper portion to the insertion hole at the lower portion, and a sub-reinforcing bead connected to the main reinforcing bead. Referring to fig. 2, some reinforcing ribs 3 extend from the upper pin shaft 2 to the lower pin shaft 2, i.e. main reinforcing ribs, and in addition, the side portions of the main reinforcing ribs are connected with some branch reinforcing ribs which extend in other directions and have shorter lengths, so that the overall strength of the rack can be further improved by more reinforcing ribs extending in different directions.
Alternatively, the riser 1 comprises a plurality of corners, each provided with the receptacle. The projection of the rack in the extending direction of the supporting tube 4 is an irregular pattern, which is approximately the shape of the vertical plate 1, referring to fig. 2, the vertical plate 1 can be formed into a roughly quadrilateral shape, and has four corners, and each corner is provided with the insertion hole, so that the four corners of the vertical plate 1 are connected through the pin shaft 2, and the stability of the overall connection is realized. In particular, the rack is located approximately in the middle of the riser 1, extending downwards from between two vertically extending ribs 3.
