Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, and particularly relates to a front counterweight for a tractor. Background Art

[0002] Today, with the rapid development of agricultural mechanization, tractors, as the main power source for farmland operations, the stability of their performance and the improvement of work efficiency have become the common focus of farmers and agricultural machinery manufacturers. When a tractor is operating in the field, especially in an environment with complex soil conditions and uneven terrain, its stability and traction are particularly important. In order to enhance the stability of the tractor, especially during heavy-duty operations, the reasonable design and configuration of the counterweight system have become an essential part.

[0003] Traditional tractor counterweight methods mostly use a single large counterweight iron directly fixed to the rear or a specific position of the tractor. Although this method is simple and direct, there are some limitations in practical applications. For example, the counterweight block is not easy to disassemble and adjust its position, and it is difficult to adapt to the change of weight distribution under different operation requirements; at the same time, the large counterweight is also relatively bulky and inconvenient during transportation and installation.

[0004] To overcome the above disadvantages, in recent years, some detachable and combinable tractor counterweight designs have gradually emerged on the market. These designs use modular counterweight blocks, allowing users to flexibly combine and adjust the number and position of the counterweights according to actual needs to achieve the best stability effect. However, there are still some deficiencies in the connection method and structural strength of the existing modular counterweight designs, such as the connecting parts are easy to loosen, the positioning between the counterweight blocks is inaccurate, and the overall structural stability needs to be improved, etc., which need to be improved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a front counterweight for a tractor with firm connection and not easy to loosen for the above problems.

[0006] To achieve the above purpose, the utility model discloses a front counterweight for a tractor, including a counterweight block, and its structural feature is that: one side part of the counterweight block is provided with a positioning hole, and the other side part of the counterweight block is provided with a positioning block whose position corresponds to the positioning hole on the adjacent counterweight block. The positioning block extends horizontally and bends downward, and the shapes of the positioning block and the positioning hole match, and the positioning block is inserted into the positioning hole of the adjacent counterweight block.

[0007] Precise docking and positioning between the counterweight blocks are realized, and rapid assembly and disassembly can be carried out without additional tools. The horizontally extending and downward bending structure of the positioning block increases the connection stability and tensile resistance, ensuring that the counterweight blocks will not loosen or fall off during the operation of the tractor. The overall stability of the counterweight system is improved, and at the same time, the process of installing and replacing the counterweight blocks is simplified, and the work efficiency is improved.

[0008] There are two positioning blocks, and the two positioning blocks are spaced apart from each other left and right. The double-positioning-block design further enhances the connection strength between the counterweight blocks. The layout with left and right spacing helps to disperse the force and reduce the risk of single-point force application. It improves the stability and durability of the counterweight block combination, ensuring a good connection state even under complex working conditions.

[0009] The number and arrangement positions of the positioning holes are adapted to the positioning blocks. This ensures that the positioning blocks can be accurately inserted into the positioning holes, avoiding installation problems caused by misalignment or size mismatch, and reducing faults and maintenance costs caused by improper installation.

[0010] The shape and size of the positioning holes are larger than those of the positioning blocks, allowing a certain assembly gap, which facilitates the insertion and adjustment of the positioning blocks. At the same time, it also helps to maintain the connection stability under conditions such as thermal expansion and contraction.

[0011] A fillet is provided at the entrance of the positioning hole. The fillet design reduces the friction and resistance during the insertion of the positioning block, improves the smoothness of the installation process, and reduces the risk of damage caused by improper installation.

[0012] Connection holes are provided on the counterweight blocks, and bolts for fixedly connecting multiple counterweight blocks are inserted into the connection holes. The bolt connection provides additional fixing force, further enhancing the connection strength between the counterweight blocks, ensuring the stability of the overall structure, maintaining the stability of the counterweight system even under extreme working conditions, and improving the operation safety and efficiency of the tractor.

[0013] Installation grooves are provided on both sides of the counterweight blocks, and the connection holes are located in the installation grooves. The design of the installation grooves provides installation space for the bolts and the mounting plate, improves the integrity and aesthetics of the connection structure, and also helps to protect the bolts and connection holes from the direct influence of the external environment.

[0014] A mounting plate is installed in the installation groove, and the bolt passes through the mounting plate. The mounting plate increases the force-bearing area of the bolt connection, disperses the stress concentration of the bolt, improves the connection strength and durability, further enhances the stability and reliability of the counterweight system, and extends the service life.

[0015] In summary, the beneficial effects of the present utility model are as follows: It realizes the precise docking and positioning between the counterweight blocks, and can be quickly assembled and disassembled without additional tools. The horizontally extending and downwardly bent structure of the positioning blocks increases the connection stability and tensile resistance, ensuring that the counterweight blocks will not loosen or fall off during the operation of the tractor. It improves the overall stability of the counterweight system, simplifies the process of installing and replacing the counterweight blocks, and improves the work efficiency.
