Description

Technical Field

[0001] This utility model relates to the field of rice transplanter technology, specifically a rice transplanter paddy field wheel height adjustment device. Background Technology

[0002] Currently, most rice transplanters use a power unit at the front that drives two paddy field wheels equipped with planting feet to move the entire transplanter through the paddy field. The transplanting mechanism is powered by the power transmission and ensures that the entire bottom surface of the transplanter body and the seed shovel at the rear of the machine is in good contact with the mud surface of the paddy field to ensure smooth transplanting. Compared with manual transplanting or manual rice transplanters, this method is more convenient to operate and use, and also improves the efficiency of transplanting.

[0003] However, existing paddy field wheels for rice transplanters still have some shortcomings in use. For example, although they can assist the rice transplanter in moving in paddy fields, they do not have a self-locking height adjustment mechanism and cannot adjust the height of the paddy field wheels according to usage needs, thus reducing the applicability of the paddy field wheels for rice transplanters and failing to meet the needs of today's market.

[0004] Therefore, this utility model provides a height adjustment device for the paddy field wheel of a rice transplanter to solve the above problems. Utility Model Content

[0022] 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.

[0023] This utility model provides a height adjustment device for the paddy field wheel of a rice transplanter, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom surface of the mounting base 1 is fixedly connected to a housing 2, the top of the inner part of the housing 2 is fixedly connected to a base 3, the bottom surface of the base 3 is fixedly connected to a sleeve 4, the inside of the sleeve 4 is slidably connected to a telescopic rod 6, the side surface of the telescopic rod 6 is provided with a rack, the bottom surface of the mounting base 1 is fixedly connected to two fixing blocks 5, the inside of the fixing blocks 5 is rotatably connected to a connecting column 8, the two ends of the connecting column 8 are fixedly connected to gears 7, the end of the telescopic rod 6 away from the base 3 is fixedly connected to a lifting plate 9, the bottom surface of the mounting base (1) is fixedly connected to a fixing plate (16), the fixing plate (16) and the fixing block (5) are rotatably connected to a worm gear (15), the worm gear (15) meshes with the gear (7), the side of the fixing plate (16) away from the worm gear (15) is fixedly connected to a drive motor (14), the output shaft of the drive motor (14) is fixedly connected to one end of the worm gear (15).

[0024] When using the paddy field wheel height adjustment device for this rice transplanter, after the drive motor 14 starts, it drives the worm 15 to rotate through the output shaft. Since the worm 15 meshes with the gear 7, the rotation of the worm 15 will drive the drive gear 7 to rotate. The meshing of the worm 15 and the gear 7 increases the stability of the transmission, and there will be no shaking or deviation during the adjustment process, which improves the working efficiency and stability of the rice transplanter. The rotating gear 7 drives the connecting column 8 to rotate. Since the gear 7 meshes with the rack on the side surface of the telescopic rod 6, the rotation of the gear 7 can drive the telescopic rod 6 to slide inside the sleeve 4, thereby adjusting the height of the lifting plate 9. After the height of the lifting plate 9 is adjusted, it can adapt to paddy fields of different depths to achieve the purpose of adjusting the height of the paddy field wheel.

[0025] Furthermore, in order to limit the movement of the lifting platform 9 and improve its stability, such as... Figure 2 , Figure 3 and Figure 4 As shown, a first fixing head 19 is fixedly connected to the bottom surface of the mounting base 1. An upper connecting rod 18 is rotatably connected to one end of the first fixing head 19 away from the mounting base 1. A lower connecting rod 20 is rotatably connected to the other end of the upper connecting rod 18. A second fixing head 21 is rotatably connected to the other end of the lower connecting rod 20. The end of the second fixing head 21 away from the lower connecting rod 20 is fixedly connected to the top surface of the lifting plate 9.

[0026] When the height adjustment device for the paddy field wheel of the rice transplanter is in use, when the height of the lifting plate 9 changes, the first fixed head 19 serves as a fixed point, and the upper connecting rod 18 will rotate around the first fixed head 19, thereby driving the lower connecting rod 20 and the second fixed head 21 connected thereto to make corresponding movements. This ensures that the lifting plate 9 moves smoothly in the vertical direction, while also limiting the maximum distance between the lifting plate 9 and the mounting base 1.

[0027] Furthermore, in order to make the gear 7 rotate and drive the telescopic rod 6 to slide, such as Figure 2 As shown, a first groove 17 is provided on the side surface of the sleeve 4, and the gear 7 meshes with the rack through the first groove 17. When this rice transplanter paddy wheel height adjustment device is in use, the first groove 17 ensures that the gear 7 can maintain a stable meshing relationship with the rack without interfering with the sliding of the telescopic rod 6, thus ensuring the smooth progress of the adjustment process.

[0028] In order to maintain the casing 2, such as Figure 1 As shown, a maintenance plate 10 is provided on one side of the housing 2, and a fixing screw 11 is provided through the surface of the maintenance plate 10. The maintenance plate 10 and the housing 2 are fixedly connected by the fixing screw 11.

[0029] When using the height adjustment device for the paddy field wheel of the rice transplanter, if it is necessary to inspect or maintain the inside of the housing 2, the inspection plate 10 can be removed from the housing 2 by loosening the fixing screws 11, so as to easily access the various components inside the device.

[0030] It should be noted that, in order to increase friction, such as Figure 1 As shown, the top surface of the mounting base 1 is provided with a second groove 22, and an anti-slip pad 23 is fixedly connected inside the second groove 22. The surface of the anti-slip pad 23 is provided with anti-slip texture. When this rice transplanter paddy wheel height adjustment device is in use, the addition of the second groove 22 and the anti-slip pad 23 on the top surface of the mounting base 1 can increase the friction, thereby improving the stability of the rice transplanter paddy wheel height adjustment device after installation.

[0031] Furthermore, in order to carry out operations on paddy fields, such as... Figure 1 and Figure 2 As shown, a box 24 is fixedly connected to the bottom surface of the lifting plate 9, and a cylinder 12 is rotatably connected inside the box 24. The two ends of the cylinder 12 are fixedly connected to the paddy field wheel body 13.

[0032] When using the height adjustment device for the paddy field wheel of this rice transplanter, the design of the box 24 on the bottom surface of the lifting plate 9 ensures the stability of the paddy field wheel body 13 during rotation. The two ends of the cylinder 12 are firmly connected to the paddy field wheel body 13, so that the paddy field wheel body 13 can operate smoothly and efficiently when receiving power. By adjusting the height of the lifting plate 9, the contact depth between the paddy field wheel body 13 and the ground can be flexibly controlled, thereby adapting to different levels of mud in paddy fields and crop planting needs. The shell 2 is fixedly connected to the rice transplanter on the side away from the maintenance plate 10, so when adjusting the height, only the lifting plate 9 and the box 24 are adjusted.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
