[0027] The overall front suspension counterweight of the present embodiment is used in cooperation with the front suspension load of the tractor, specifically, the upper pull rod of the front suspension of the tractor is assembled with the upper pull rod support 2, and the lower pull rod is assembled with the lower pull rod supports 3 on both sides. Since the height of the lower pull rod supports 3 on both sides of the counterweight 1 can be adjusted, the ground clearance of the counterweight 1 can be selected differently, and it can be adapted to different models of tractors. At the same time, the traction structure is provided on the front side of the counterweight 1, which can be connected with the traction equipment and achieve the purpose of towing the whole vehicle. Overall, the structure is simple and reasonable, the ground clearance of the whole counterweight can be adjusted, and at the same time, the traction structure is provided to facilitate towing during use.

[0028] In the present embodiment, the upper pull rod support 2 includes a bottom plate 21 and two side plates 22, the bottom plate 21 is fixed on the upper end of the counterweight 1 by bolts, the two side plates 22 are distributed left and right with a vertical fixed plate 21 on the upper end, and the upper part of the two side plates 22 is respectively provided with two groups of assembly pin holes 221 spaced vertically. The design of two groups of assembly pin holes 221 with different heights can adapt to the pin connection of the upper pull rod of the front suspension of the two / three category tractors.

[0029] In the embodiment, the lower pull rod support 3 comprises a fixed plate 31 and a pull rod pin 32. The fixed plate 31 is provided with fastening bolts, and the side end of the counterweight 1 is provided with a plurality of bolt holes matched with the fastening bolts. The plurality of bolt holes are vertically spaced. The fastening bolts are assembled with any one or more groups of bolt holes to adjust the height of the fixed plate 31. The pull rod pin 32 extends in the left-right direction and is vertically connected to the fixed plate 31 at one end. For example, the fixed plate 31 is assembled by four vertically and horizontally distributed fastening bolts. Five groups of bolt holes are arranged at the side end of the counterweight 1, each group of bolt holes is provided with two bolt holes, and the spacing of the two fastening bolts is consistent with the horizontal direction. When the fixed plate 31 is assembled by the fastening bolts and the bolt holes, the adjacent two groups of bolt holes can be selected for assembly, that is, the assembly height of the fixed plate 31 has multiple changes, so that the ground clearance of the counterweight 1 has multiple sizes to adapt to different types of tractors, and the universality is better.

[0030] As a preferred embodiment, the front side of the counterweight 1 is provided with a vertical recess, and a limiting partition 11 is arranged at the middle of the recess. The middle region of a plurality of limiting partitions 11 is vertically provided with a positioning hole.

The lower end of the positioning pin 41 is horizontally provided with a plug hole matched with the locking bolt 412. The cross-sectional area of the limiting head 411 is larger than that of the positioning hole, so that when the positioning pin 41 is assembled, it is vertically inserted from top to bottom. The lower end of the positioning pin 41 penetrates the lower partition 11, and then the locking bolt 412 is inserted at the lower end of the positioning pin 41 to limit the positioning pin 41 in the positioning hole.

[0033] In the embodiment, as shown in Figure 4As shown, the middle position of the limiting head 411 is provided with a ring groove, the flexible connecting piece 4111 is a metal chain, one end of the flexible connecting piece 4111 is provided with a link ring sleeved in the ring groove, one end of the locking bolt 412 is rotatably provided with a limiting ring 413, and the other end of the flexible connecting piece 4111 is connected with the limiting ring 413. Through the design of the link ring, the locking bolt 412 and the positioning pin 41 are well connected and are not easy to lose. Meanwhile, the limiting ring 413 and the locking bolt 412 are rotatably connected with damping effect, and the limiting ring 413 can be rotated to an angle and then kept.

[0034] In the embodiment, the upper end of the counterweight 1 is concavely provided with a tool groove 12 for placing tools. Agricultural machinery maintenance tools can be placed in the tool groove 12. Meanwhile, the design of the tool groove 12 can increase the volume of the counterweight 1 while ensuring that the weight of the entire counterweight 1 remains unchanged, and the overall assembly is more stable.

[0035] In the embodiment, the upper end of the tool groove 12 is hingedly connected with a box cover 13 which can be turned to open or close.

[0036] In the embodiment, one side of the box cover 13 is hingedly connected with one side of the upper end of the tool groove 12, the other side of the box cover 13 is provided with a lock 131, and the other side of the upper end of the tool groove 12 is internally provided with a lock seat matched with the lock 131, and the lock 131 can be locked with the lock seat when the box cover 13 is closed. The lock seat is arranged in the tool groove 12 and is not easy to be damaged and opened, and the safety is high.
