植機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a ground sensor for detecting planting depth that operates up and down as the planting device moves up and down and rolls freely relative to the running machine. A mechanism for adjusting, a sensor for detecting the horizontal attitude of the planting device, and a mechanism for moving the planting device relative to the machine so that the planting device is maintained in the set posture based on the detection result of the horizontal detection sensor. The present invention relates to a rice transplanter provided with a control mechanism for rolling the planting device, and a mechanism capable of adjusting flexibility for freely rolling the planting device around the set posture.

に修正できる利点があるが、このような利点を最
大限、有効に発揮するには、圃場の硬軟に応じて
融通の大きさを適切に調整する必要がある。 In such rice transplanters, flexibility is provided to allow a certain degree of free rolling of the planting device relative to the running main machine due to ground reaction force, so if the planting device momentarily rolls slightly, the attitude detection sensor and Although the rolling of the planting device cannot be adequately coped with by using only the control mechanism, there is an advantage that the planting device can be quickly corrected to the set posture by the free rolling of the planting device. In order to achieve maximum effectiveness, it is necessary to appropriately adjust the amount of flexibility depending on the hardness and softness of the field.
なぜなら、圃場が軟い場合において融通が大き
いと、接地反力が小さくて植付装置のローリング
に対する対地支持力が弱いから、例えば、植付装

おいて融通が小さいと、一般に、硬い圃場ほど地
面の凹凸が激しい故に、自由ローリング量が不測
して、前記の融通を設けることによる利点を活し
きれないからである。 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. As mentioned above, when the planting equipment rolls unreasonably due to lateral movement, the posture stability of the planting equipment decreases, and conversely, when the field is hard, if the flexibility is small, it generally causes the planting equipment to roll unduly. This is because the ground is more uneven in the field, so the amount of free rolling becomes unpredictable, making it impossible to take advantage of the advantages of providing the above-mentioned flexibility.
本発明は、かかる実状に鑑み、前述の融通調整
を適切、かつ、合理的に行なえるようにしようと

拘わらず植付け性能の向上が図れるに至つた。 In other words, in order to adjust the planting depth appropriately and well, we focused on the fact that the sensing load of the ground sensor is adjusted appropriately according to the hardness and softness of the field, and we have developed a flexible method for adjusting the sensing load of the ground sensor. The greatest feature of the present invention is that by linking the adjustments, the flexibility is automatically adjusted to an appropriate value according to the hardness and softness of the field. Although there is no need for special operations for this purpose, the flexibility can be adjusted appropriately depending on the hardness and softness of the field, making it possible to improve planting performance regardless of the hardness or softness of the field.
