Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery, specifically a rice transplanter with an anti-sinking mechanism. Background Technology
[0002] A rice transplanter is an agricultural machine used for rice cultivation. It is mainly used to insert rice seedlings into paddy fields in an orderly manner. It consists of basic components such as a seedling box, a transplanting mechanism, a frame, and a float. Some models are also equipped with a power drive and a walking device.
[0003] A Chinese patent with publication number CN210868702U discloses a high-speed rice transplanter, wherein the high-speed rice transplanter includes a transplanter body and a power unit, wherein the power unit includes an engine and a starter motor, wherein the engine includes an engine body and at least one limiting body, the limiting body extending from the engine body, wherein the starter motor includes a motor body and at least one mounting body, wherein the mounting body extends from the motor body, the mounting body of the starter motor is mounted on the limiting body of the engine, and the motor body is held on one side of the engine body.
[0004] Rice transplanters often operate on paddy field ridges, but due to the uneven and soft mud on these ridges, they are prone to getting stuck. To prevent this, existing solutions and technologies typically modify the wheels, increasing their size and adding more mud-tumbling blades to improve the contact area with the ground and reduce the likelihood of getting stuck. However, while the fixed mud-tumbling blade structure facilitates movement in muddy areas, the intermittent contact between the blades and the ground on hard surfaces after work results in a very bumpy ride. Even slight acceleration exacerbates the bumps, significantly impacting the driving experience. Therefore, there is a lack of suitable anti-sinking rice transplanter wheel structures that allow for stable movement on roads, necessitating improvement and optimization. Utility Model Content

[0025] In use, the central axle ring 2 is inserted into one end of the wheel axle 1, and the screw pin 3 is screwed onto the central axle ring 2 and the wheel axle 1 to fix the wheel. Multiple sets of support rods 4 are fixedly welded to the central axle ring 2 and the inner wall of the wheel rim 5 at both ends to improve the support force of the wheel. Multiple sets of rotating grooves 6 with rotating grooves 601 connected to the inner side of the wheel rim 5 cooperate with the rotating grooves 601 on the outer ring of the wheel rim 5 so that the rotating locking assembly can rotate on the rotating grooves 601. The anti-slip protrusions 501 are used for anti-slip and direct contact with the ground when driving on the road.
[0026] Example 2: Based on Example 1, the rotary mud-turning assembly includes a first rotating half-ring 701, with a second rotating half-ring 707 fixedly bolted to one end of the first rotating half-ring 701. The first rotating half-ring 701 is rotatably connected to the rotating groove 6, and the second rotating half-ring 707 is rotatably connected to the rotating groove 6.
