[0023] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model, and are not used to limit the scope of the utility model.
[0024] Example 1
[0025] like Figure 1 , 2 As shown, the easily detachable and assembleable small tractor rear counterweight of this embodiment includes a counterweight block 1, a connecting frame 2, and a mounting point 3. The connecting frame 2 is installed on the upper front side of the counterweight block 1. The mounting point 3 is provided in two sets and is installed on the left and right sides of the counterweight block 1 respectively. The connecting frame 2 is used to assemble with the upper tie rod of the tractor's rear suspension, and the mounting point 3 is used to connect with the end of the lower tie rod of the tractor's rear suspension.
[0026] This embodiment features a small tractor rear counterweight designed for easy assembly and disassembly. Without reducing the tractor's departure angle or increasing the overall length, the counterweight is installed as far back as possible on the tractor to achieve a better rearward shift of the center of gravity. Simultaneously, the dimensions of the counterweight attachment point 3 conform to the 1N class rear suspension attachment size standard, allowing for quick attachment and disassembly. During assembly, the counterweight is placed on a horizontal surface at the same height as the tractor. The ground clearance of attachment point 3 is greater than the minimum height of the tractor's rear suspension lower control rod. Therefore, no lifting tools are required during installation; simply drive the tractor to a suitable position and raise the rear suspension to complete the counterweight attachment. The counterweight block 1 is connected and assembled to the upper and lower control rods of the rear suspension via the top connecting frame 2 and the side attachment point 3, effectively counteracting the forward shift of the center of gravity during front-loading operations.
[0027] In this embodiment, the connecting frame 2 is a connector between the counterweight 1 and the upper tie rod of the tractor's rear suspension. The height of the counterweight 1 is designed to be too low, so it cannot be directly connected to the upper tie rod. Therefore, the connecting frame 2 can increase the height of the connection point of the counterweight 1 so that it can be hooked to the upper tie rod.
[0028] In a preferred embodiment, the connecting frame 2 includes a base plate 21 and vertically arranged upright plates 22 spaced apart on the upper end of the base plate 21. The two upright plates 22 are respectively provided with locating pin holes that pass through from left to right at the same height on the upper end. The end of the upper tie rod of the tractor rear suspension extends between the two upright plates 22 and is assembled by locating pins that pass through the locating pin holes and the locating pins of the upper tie rod of the tractor rear suspension. The base plate 21 is mounted to the upper front side of the counterweight 1 by bolts that pass through it. A reinforcing rib plate 221 is connected between the two upright plates 22.
[0029] In the above implementation scheme, the connecting frame 2 is firmly assembled with the counterweight 1 through the base plate 21, and a good pin connection is achieved with the upper tie rod of the rear suspension through the two upright plates 22 and the positioning pin hole. The reinforcing rib plate 221 can improve the structural strength between the upright plates 22 and ensure a firm assembly between the upper tie rod of the rear suspension and the counterweight 1.
[0030] In the embodiment, the upper end of the counterweight 1 is provided with a support platform 11 at the front side of the middle part, and the bottom plate 21 is mounted on the upper end of the support platform 11. The design of the support platform 11 can improve the assembly height of the connecting frame 2 to some extent, and ensure that the gravity center of the counterweight 1 is offset to the lower rear side of the equipment, and the gravity center is relatively stable.
[0031] As a preferred embodiment, the support platform 11 is provided with a hole passing through the front and back.
[0032] In the embodiment, the hole is designed to form a "ear seat" structure for hoisting, which is a clever design.
[0033] In the embodiment, the hanging point 3 includes a hanging pin 31 arranged horizontally along the left-right direction.
[0034] As a preferred embodiment, one end of the hanging pin 31 is provided with a mounting plate 32 perpendicular to the hanging pin 31, and the mounting plate 32 is attached to the side end of the counterweight 1 and connected and assembled with the counterweight 1 by bolts.
[0035] In the embodiment, the hanging pin 31 and the counterweight 1 are firmly assembled through the large-area mounting plate 32, and the hanging pin 31 can bear a large force after assembly.
[0036] In the embodiment, the counterweight 1 is provided with a reinforcing boss 12 at the same height on both sides, and the side of the reinforcing boss 12 away from each other is provided with a parallel plane, and the mounting plate 32 is attached to the corresponding reinforcing boss 12 on the side and connected and assembled with the reinforcing boss 12 by bolts. The reinforcing boss 12 enhances the structural strength of the assembly part between the counterweight 1 and the mounting plate 32.
[0037] As a preferred embodiment, as shown in the figure, Figure 3 the end of the hanging pin 31 away from the mounting plate 32 is provided with a circular limiting sleeve 311, and the limiting sleeve 311 and the end of the hanging pin 31 are provided with a limiting pin hole passing through radially, and a limiting pin 312 is detachably arranged in the limiting pin hole.
[0038] In the embodiment, a ball head is inserted on the hanging pin 31 during actual assembly, and the end of the connecting frame 2 is connected to the hanging pin 31. When the suspension is assembled, the lower pull rod of the suspension is translated to the lower side of the hanging pin 31, and the end of the lower pull rod is provided with a ball socket matched with the ball head. The ball socket and the ball head are embedded, and the upper pull rod and the connecting frame 2 are assembled, so that the counterweight and the tractor are well assembled.
[0039] As a preferred embodiment, the upper end of the counterweight 1 is provided with a functional groove 13.
[0040] In the above embodiment, the functional recess 13 can increase the volume of the weight block 1 to a certain extent without changing the weight of the weight block 1, facilitate the assembly and connection with the pull rod, and the functional recess 13 can also be used to place corresponding tools or objects, of course, the functional recess 13 can also be used as a weight cavity to increase the weight, and when the weight is insufficient, additional weight pieces can be filled into the functional recess 13.
