Description

Technical Field

[0001] This utility model relates to the field of counterweight accessories technology, specifically to an easily adjustable counterweight accessory for agricultural machinery. Background Technology

[0002] In agricultural mechanized operations, the balance of agricultural machinery is a key factor in ensuring operational safety and efficiency. Different operational scenarios have significantly different requirements for the center of gravity position and counterweight of agricultural machinery.

[0003] However, the counterweight components of existing agricultural machinery generally have some shortcomings. Adjustment is cumbersome, relies on tools, and is inefficient. Traditional counterweights mostly adopt an integrated structure fixed by bolts. When increasing or decreasing the weight, each bolt must be disassembled. When adjusting the position, tools such as wrenches are needed to loosen the fixing parts. The whole process is time-consuming and laborious. Especially in emergency scenarios such as field operations, frequent adjustments will seriously affect the progress of the operation. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: an easily adjustable agricultural machinery counterweight accessory, comprising: a fixing device 1, a counterweight structure 2 slidably connected to the outer wall of the fixing device 1, and the counterweight structure 2 arranged in a transverse array along the fixing device 1; the counterweight structure 2 includes a counterweight block 21, a fixing hole 22 is provided on the outer wall of the counterweight block 21, a sliding groove 23 is symmetrically provided on the outer wall of the counterweight block 21, a sliding rod 24 is symmetrically fixedly connected to the inner wall of the sliding groove 23, a pull plate 25 is slidably connected to the outer wall of the sliding rod 24, a clamping block 26 is fixedly connected to the outer wall of the pull plate 25, and a compression spring 27 is fixedly connected to the outer wall of the pull plate 25 on the side away from the clamping block 26.

[0025] The counterweight 21 has grooves on both sides. The outer wall of the compression spring 27 away from the pull plate 25 is fixedly connected to the inner wall of the slide 23. The outer walls of the clamping block 26 and the pull plate 25 are slidably connected to the inner wall of the slide 23. When the operator pulls the pull plate 25 inward, the pull plate 25 compresses the spring 27 and drives the clamping block 26 to retract into the slide 23.

[0026] The inner wall of the fixing hole 22 is slidably connected with a bidirectional threaded rod 28, and the outer wall of the bidirectional threaded rod 28 is symmetrically threaded with nuts 29. Multiple counterweights 21 are stacked in alignment so that the fixing holes 22 of each block are coaxially connected. After inserting the bidirectional threaded rod 28, the nuts 29 at both ends are tightened symmetrically to fix the weight.

[0027] The fixing device 1 includes a fixing block 11, a fixing plate 12 is fixedly connected to the outer wall of the fixing block 11, a fixing screw 13 is slidably connected to the inner wall of the fixing plate 12, and a positioning groove 14 is provided on the outer wall of the fixing block 11 away from the fixing plate 12.

[0028] The positioning groove 14 is arranged horizontally along the outer wall of the fixing block 11. The fixing plate 12 is installed on the machine by fixing screws 13. The fixing device 1 is the installation base of the entire counterweight accessory. Its core function is to stably connect the accessory to the agricultural machinery.

[0029] The inner wall of the counterweight 21 is slidably connected to the outer wall of the fixed block 11, the outer wall of the clamping block 26 is slidably connected to the inner wall of the positioning groove 14, and the fixed block 11 serves as the sliding base of the counterweight 21, with its outer wall slidably engaged with the inner wall of the counterweight 21, providing a guide track for the lateral sliding of multiple counterweights 21.

[0030] When in use, the fixing device 1 is the installation base of the entire counterweight assembly. Its core function is to stably connect the assembly to the agricultural machinery. The counterweight structure 2 is distributed in a "horizontal array" manner, and the number of counterweight blocks 21 can be adjusted to adjust different weights.

[0031] The fixing plate 12 is rigidly fixed to the preset installation position of the agricultural machinery by fixing screws 13, ensuring that the entire device does not loosen in the vibration and bumpy environment of agricultural machinery operation. The fixing block 11 serves as the sliding base of the counterweight block 21, and its outer wall slides in cooperation with the inner wall of the counterweight block 21, providing a guide track for the lateral sliding of multiple counterweight blocks 21. At the same time, the positioning grooves 14 arranged laterally on the outer wall of the fixing block 11 are the key structure for positioning the counterweight block 21, and the position is locked by fitting with the clamping block 26.

[0032] First, slide the counterweight 21 into the outer wall of the fixed block 11 by aligning its groove with the fixed block 11. At this time, the fixed block 11 presses the clamping block 26, causing it to slide inward along the slide groove 23 via the slide rod 24. Simultaneously, the compression spring 27 is compressed and contracted. When the clamping block 26 is aligned with the positioning groove 14, the compression spring 27 releases its elasticity, applying an outward pushing force to the pull plate 25, causing the clamping block 26 to extend out of the slide groove 23 and embed into the positioning groove 14 of the fixed block 11. At this time, the counterweight 21 is locked by the engagement between the clamping block 26 and the positioning groove 14, preventing it from sliding along the fixed block 11. Conversely, when it is necessary to adjust the number of counterweights 21 or disassemble them, the operator pulls the pull plate 25 inward. The pull plate 25 compresses the spring 27 and causes the clamping block 26 to retract into the slide groove 23, separating the clamping block 26 from the positioning groove 14. At this time, the counterweight 21 is unlocked and can slide freely along the fixed block 11.

[0033] Multiple counterweight blocks 21 are aligned and stacked so that the fixing holes 22 of each block are coaxial and connected. After inserting the bidirectional threaded rod 28, the nuts 29 at both ends are tightened symmetrically. The thread preload is used to clamp the stacked counterweight blocks 21 into a whole to prevent the counterweight blocks 21 from loosening.
