機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pair of left and right mud ground floats at the rear of the planting device that can roll with respect to the traveling machine body in order to detect rolling of the planting device due to changes in the undulation of the tiller. The float is mounted so as to be able to swing up and down around a fulcrum, and a mechanism for detecting the swinging posture of the float is provided between the front part of the float and the planting device, and this detection mechanism and the rolling drive mechanism of the planting device are interlocked and connected. The planting device is configured to roll-control the planting device in a horizontal position with respect to the ground based on the detection result by the detection mechanism, and the planting device is further provided with a planting depth adjustment mechanism that can freely change and fix the rear fulcrum of the float up and down.

があつた。 Conventional rice transplanters of this type simply provide a float-side detection member on the front part of the float and a main-side detection member on the main machine side, and detect changes in the relative distance between the two using the above-mentioned method. Since the device is configured to detect only by changes in the relative positions of the detection members, adjusting the planting depth will change the vertical relative distance between the front part of the float and the device. There is a problem in that when the float is in a constant swinging posture with respect to the machine, the vertical relative relationship between the machine-side detection member and the float-side detection member changes, making it impossible to perform accurate detection. Ta.

る。 In order to achieve the above object, the present invention is characterized in that a planting device is connected to a traveling machine body in a rolling manner, and a pair of left and right mud ground floats are vertically swung around a rear fulcrum with respect to the planting device. A mechanism for detecting the swinging posture of the float is provided between the front part of the float and the planting device, and the detection mechanism is interlocked with the rolling drive mechanism of the planting device. The rice planting device is configured to perform rolling control on the planting device in a horizontal position relative to the ground based on the detection result obtained by In the machine, a detection member is placed between the planting depth adjustment mechanism and the detection member on the planting device side or the detection member 8B on the float side in the detection mechanism, as the planting depth adjustment mechanism operates. It is provided with an interlocking mechanism that changes the position up and down in the same direction, and this configuration provides the following effects.

作用を正確に行ない得るに至つた。 In other words, the detection member on the machine side or the detection member on the float side changes its position up and down in conjunction with the operation of the planting depth adjustment mechanism, and the vertical relative position between the front part of the float and this machine is adjusted as the planting depth is adjusted. Regardless of distance fluctuations, the relative positional relationship between both detection members can be automatically maintained constant when the float is in a constant swinging posture with respect to the machine, so rolling by the float and detection mechanism can always be maintained. The desired detection action could be performed accurately.
