Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a ground sensor for detecting planting depth that operates up and down as the planting device moves up and down and can freely roll with the LCL L; A mechanism for adjusting the load, a sensor for detecting the horizontal attitude of the planting device, and a mechanism for moving the planting device so that the planting device i is maintained in a set posture based on the detection result of the horizontal detection sensor. Rolling control system for this machine 6tl + 1
The present invention relates to a rice transplanter which is provided with a mechanism capable of adjusting the flexibility of freely rolling the wA example device around the set posture.

Such rice transplanters are flexible enough to allow a slight rolling of the planting device against the running machine due to ground reaction force, so if the planting device momentarily rolls slightly, the posture detection sensor and control Even if the rolling mechanism cannot fully cope with the rolling, there is an advantage that the planting device can be quickly adjusted to the set posture by the free rolling of the planting device. In order to achieve this, it is necessary to appropriately adjust the amount of flexibility depending on the hardness and softness of the field.

This is because if the field is soft and the flexibility is large, the ground reaction force is small and the ground supporting force against rolling of the planting device is weak. On the contrary, the lateral movement of the mind causes the planting device to roll unreasonably large.
If the stability of the planting device's posture decreases, or if the flexibility is small when the field is hard, the amount of free rolling will be unpredictable due to the roughness of the ground in hard fields, and the above-mentioned problem will occur. This is because the benefits of providing flexibility cannot be fully utilized.

In view of such actual circumstances, the present invention appropriately implements the above-mentioned flexibility adjustment.
And the purpose is to make it possible to do it rationally.

The rice transplanter according to the present invention is provided with a linkage mechanism that automatically and reversibly adjusts the accommodation adjustment mechanism to the side with greater flexibility in conjunction with the adjustment operation of the sensing load adjustment mechanism towards the larger load side. It is characterized by

In other words, in order to properly and properly adjust the planting depth,
The sensing load of the ground sensor is adjusted appropriately according to the hardness and softness of the field.
The biggest feature is that by focusing on the points to be adjusted and linking the flexibility adjustment to the sensing load adjustment of the ground sensor, the flexibility is automatically adjusted to an appropriate value according to the hardness and softness of the field. Therefore, according to the present invention, there is no need for special operations for adjustment of flexibility, but the flexibility is made appropriate according to the hardness and softness of the field, and the planting performance is maintained regardless of the hardness or softness of the field. We have been able to improve this.
