Technical Field

[0001] The utility model relates to the field of high-speed rice transplanters, in particular to a steering detection device for rice transplanters. Background Art

[0002] In existing agricultural machinery technology, riding rice transplanters are the main rice transplanting agricultural machinery equipment, which are of great help in transplanting rice. The operator does not need manpower to perform the rice transplanting operation, and can complete the rice transplanting operation by driving and operating the rice transplanter. However, the existing rice transplanters have not yet achieved fully automated operation, so the operator needs to drive the rice transplanter to lift or lower the planting part and cooperate with the rice transplanter to perform a series of operations such as acceleration and deceleration, steering or U-turn. The entire operation process requires coordination between multiple steps, and the route needs to be adjusted to prevent deviation, so this also requires high skills from the operator. Therefore, how to reduce the requirements for the operator when the rice transplanter turns or turns around, realize steering angle detection, and reduce the research and development cost of the rice transplanter is also one of the issues that need to be considered in the research and development of the rice transplanter.

[0003] Therefore, it is necessary to provide a rice transplanter steering detection device and a rice transplanter to overcome the above-mentioned defects. Utility Model Content

[0029] See also Figures 1 to 3As shown, this embodiment provides a rice transplanter steering detection device, including a steering wheel 10, a steering shaft 20, a sleeve 30, a lever 40, a slider 50, a shift fork, a sensor 60 and a support frame 70. The steering shaft 20 is connected to the lower end of the steering wheel 10 and rotates as the steering wheel 10. The outer surface of the steering shaft 20 is provided with a spiral groove 201, and the spiral groove 201 spirally rises along the axial direction of the shaft to which it is directed. The sleeve 30 is sleeved on the steering shaft 20, and the sleeve 30 is provided with a slide groove portion 301 along the axial direction of the sleeve 30. One end of the shift rod 40 is embedded in the spiral groove 201. The rotation of the steering shaft 20 drives the shift rod 40 to slide in the spiral groove 201, and the shift rod 40 then moves along the axial direction of the steering shaft 20. 50 is connected to the end of the shift lever 40 near the spiral groove 201 and moves integrally with the shift lever 40. The slider 50 includes a slider 50 main body 501 and a guide portion 502. The slider 50 main body 501 is placed between the steering shaft 20 and the sleeve 30 and is sleeved on the steering shaft 20. The guide portion 502 is placed in the slide groove portion 301. The shift fork includes a connecting end connected to the shift lever 40 and a rotating end disposed away from the shift lever 40. The connecting end is connected to the end of the shift lever 40 away from the spiral groove 201 and can rotate around the rotating end. The sensor 60 is connected to the rotating end to detect the rotation angle of the shift fork. The support frame 70 is used to fix the sleeve 30 and the sensor 60. The present invention provides a rice transplanter steering detection device that detects the steering angle of the wheel by driving the moving component to move when the steering wheel 10 rotates, thereby driving the shift fork to rotate. At the same time, the present invention has a compact structure and is highly compatible with the rice transplanter. It does not require the development of new molds, thereby reducing the research and development costs of the rice transplanter.

[0030] The rotating end has a connection hole that connects to the sensor 60. The shift fork can rotate along the connection hole. The connecting end has an open slot for connecting to the shift lever 40. Through this solution, the movement of the slider 50 and the shift lever 40 is converted into the rotation of the shift fork, thereby achieving the angle change of the sensor 60, indirectly detecting the angle change of the wheel and providing an angle signal to the processor.

The first end is embedded in the spiral groove 201, and the second end is positioned within the open chute and contacts at least one surface of the open chute. Through this solution, the first end of the lever 40 moves along the spiral groove 201. At the same time, because the guide portion 502 of the moving block is positioned within the open groove, when the steering wheel 10 rotates, the steering shaft 20 rotates. Due to the position restriction of the moving block, the lever 40 can achieve axial movement along the steering shaft 20 along the spiral groove 201. This linkage method avoids additional changes or adjustments to the rice transplanter components, reducing design and development costs.

[0034] See also Figure 5 As shown, the steering shaft 20 includes an upper end connected to the steering wheel 10 and a lower end away from the steering wheel 10.
