[0001] The utility model relates to a wheelbase adjusting device for a planting agricultural machinery, belonging to the technical field of agricultural machinery. Background Art

[0002] Agricultural machinery refers to various machines used in crop cultivation, animal husbandry, and the primary processing and handling of agricultural and livestock products. Planting machinery, in particular, plants seeds in the soil according to crop planting requirements. These machines ensure consistent spacing between plants, rows, holes, and planting depth across fields or plots. Furthermore, they minimize damage to the planting material, increase survival rates, and offer high operational efficiency.

[0003] Planting agricultural machinery can greatly improve planting efficiency and reduce farmers' labor intensity. However, the cutter wheels on commonly used planting agricultural machinery are usually fixedly installed on the agricultural machinery. According to the requirements of the planting pattern, the spacing between ridges in the farmland varies. The cutter wheels are fixedly installed on the agricultural machinery, making it difficult to adjust the spacing between the cutter wheels and difficult to adapt to the unused ridge spacing for sowing. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wheel-track adjusting device for a planting agricultural machinery, which can adjust the wheel-track between the cutter wheels according to the spacing between ridges.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] Furthermore, a slide rail is fixedly installed on the top of the fixed frame, and a slider slidably connected to the slide rail is fixedly installed on the top of the support rod.

[0008] Furthermore, a plurality of fixing plates are fixedly mounted on the inner wall of the fixing frame and the surface of the support rod, and a blocking net is mounted between two opposing fixing plates.

[0009] Furthermore, two springs are symmetrically installed inside the fixing plate, a clamping rod is fixedly installed on one end of the spring, and clamping blocks are fixedly installed on both sides of the blocking net.

[0010] Furthermore, the diameter of the clamping rod matches the inner diameter of the clamping groove on the clamping block, and a cone block is installed at one end of the clamping rod.

[0011] Furthermore, a protective box is provided on the outer side of the motor, and a heat dissipation net is installed on one side of the protective box.

[0012] Furthermore, two mounting plates are symmetrically fixedly mounted on the protection box, and bolts threadedly connected to the fixing frame are mounted on the mounting plates.

[0013] Compared with existing machines, the beneficial effects of this utility model are:

[0014] The present application can adjust the wheel spacing between the cutter wheels according to the spacing between the ridges by adjusting the wheel spacing mechanism. Before sowing, the motor is started to drive the screw in the fixed frame to rotate, thereby driving the two moving blocks to move relative to each other, so that the two moving blocks are close to or away from each other. During the movement of the moving blocks, the cutter wheels are driven to move by the support rod, and the wheel spacing between the cutter wheels is accurately adjusted through the cooperation of the scale plate and the finger plate, avoiding repeated operation and adjustment, so that the cutter wheels on the agricultural machinery can better adapt to different ridge spacings for planting, thereby improving the applicability of the planting agricultural machinery and improving the practicality of the device.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 The shown device is a wheel-track adjustment device for planting agricultural machinery, which includes an agricultural machinery frame 1, a plurality of cutter wheels 2 are provided on the agricultural machinery frame 1, a wheel-track adjustment mechanism 3 is provided on the agricultural machinery frame 1, and the wheel-track adjustment mechanism 3 includes two fixed frames 4 symmetrically fixedly mounted on the agricultural machinery frame 1, a motor 5 is fixedly mounted on one end of the fixed frame 4, a screw 6 connected to the motor 5 is movably mounted inside the fixed frame 4, two moving blocks 7 are symmetrically mounted on the screw 6, a support rod 8 connected to the moving block 7 is mounted on the cutter wheel 2, a scale plate 9 is fixedly mounted on the bottom of the fixed frame 4, and a finger plate 10 is fixedly mounted on the bottom of the support rod 8. By adjusting the setting of the wheel spacing mechanism 3, the wheel spacing between the cutter wheels 2 can be adjusted according to the spacing of the ridges. Before sowing, the motor 5 is started to drive the screw 6 in the fixed frame 4 to rotate, and then the two moving blocks 7 are driven to move relative to each other, so that the two moving blocks 7 are close to or away from each other. During the movement of the moving block 7, the cutter wheel 2 is driven to move by the support rod 8, and the wheel spacing between the cutter wheels 2 is accurately adjusted through the cooperation of the scale plate 9 and the finger plate 10, avoiding repeated operation and adjustment, so that the cutter wheel 2 on the agricultural machinery can better adapt to different ridge spacing for planting.

[0022] In this embodiment, if Figures 1-4 As shown, a slide rail 11 is fixedly installed on the top of the fixed frame 4, and a slider 12 slidably connected to the slide rail 11 is fixedly installed on the top of the support rod 8; a plurality of fixed plates 13 are fixedly installed on the inner wall of the fixed frame 4 and the surface of the support rod 8, and a blocking net 14 is installed between two opposing fixed plates 13; two springs 15 are symmetrically installed inside the fixed plate 13, and a clamping rod 16 is fixedly installed at one end of the spring 15, and a clamping block 17 is fixedly installed on both sides of the blocking net 14. When the support rod 8 is moved, the slider 12 on the support rod 8 slides in the slide rail 11. Under the support of the slide rail 11 and the slider 12, the moving block 7 and the support rod 8 can smoothly drive the cutter wheel 2 to move and adjust, thereby preventing the cutter wheel 2 from tilting. When the support rod 8 moves, the blocking net 14 installed between the fixed frame 4 can be pulled so that the blocking net 14 always covers the opening of the fixed frame 4, thereby preventing dust splashed during sowing from entering the fixed frame 4 and accumulating to cause blockage of the screw 6. The fixed plate 13 and the blocking net 14 are installed and connected by the engagement of the clamping rod 16 and the clamping block 17. Because the clamping rod 16 is supported by the spring 15, the clamping rod 16 can move up and down in the fixed plate 13. The clamping rod 16 has the function of moving up and down and can be separated from the clamping block 17, which is convenient for replacing the blocking net 14.

[0023] In this embodiment, if Figures 1-4As shown, the diameter of the clamping rod 16 matches the inner diameter of the clamping groove on the clamping block 17, and a cone block is installed at one end of the clamping rod 16; a protective box 18 is provided on the outer side of the motor 5, and a heat dissipation net 19 is installed on one side of the protective box 18; two mounting plates 20 are symmetrically fixedly installed on the protective box 18, and bolts 21 threadedly connected to the fixing frame 4 are installed on the mounting plates 20. By matching the diameter of the clamping rod 16 with the inner diameter of the clamping groove on the clamping block 17, the connection between the clamping rod 16 and the clamping block 17 is made more stable, preventing the blocking net 14 from shaking and falling; after installing the cone block at one end of the clamping rod 16, one end of the clamping rod 16 has a certain inclination, which can make it easier for the clamping block 17 to squeeze the clamping rod 16; the provision of the protective box 18 and the heat dissipation net 19 can protect the motor 5 arranged on one side of the fixed frame 4 from collision; the heat dissipation net 19 facilitates the discharge of heat to the outside; the protective box 18 is installed on the fixed frame 4 using the mounting plate 20 and the bolts 21, which not only makes the installation more secure, but also facilitates the disassembly and maintenance of the protective box 18 when the motor 5 fails.

[0024] The working process of the wheelbase adjustment device for planting agricultural machinery provided in this embodiment is as follows:

[0025] Before sowing, the motor 5 is started to drive the screw 6 in the fixed frame 4 to rotate, and then the two moving blocks 7 are driven to move relative to each other, so that the two moving blocks 7 are moved closer to or away from each other. During the movement of the moving block 7, the support rod 8 drives the cutter wheel 2 to move, and the wheel spacing between the cutter wheels 2 is accurately adjusted through the cooperation of the scale plate 9 and the finger plate 10 to avoid repeated operation and adjustment, so that the cutter wheel 2 on the agricultural machinery can better adapt to different field ridge spacing for planting.
