する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a planting device that can be installed at the front or rear of the machine, which is equipped with a driver's seat and a driving unit, and is also equipped with drive wheels arranged at one location in the longitudinal direction of the machine when viewed from the side. This planting device is equipped with a float for supporting the machine body on the ground in cooperation with the wheels, and the wheels are attached to a transmission case that is swingably pivoted with respect to the machine. It is configured so that the height position can be changed by being connected to the roadside side, and furthermore, the height of the aircraft relative to mud is maintained within a set range based on the detection results of the sensor that detects the height of the aircraft relative to mud. The present invention relates to a rice transplanter equipped with an automatic vertical adjustment mechanism that automatically adjusts the height position of the wheels.

避けられず、その結果、走行の不安定化や植付け性能の
低下を招く問題があり、かかる問題解決のための対策は
どうしても必要である。In such riding rice transplanters, it is desirable to suppress fluctuations in front and rear balance as much as possible in order to improve stable running and planting performance such as planting depth, planting posture, and mud pushing. Changes in the front-to-back balance of the machine due to the up-and-down movement of the wheels in response to the depth of the board are unavoidable, and as a result, there are problems that lead to unstable running and a decline in planting performance. Measures are absolutely necessary.
そこで、歩行型田植機としてではあるが、上下に高さ
を変更てきる走行車輪を、更に前後にも位置変更できる
ように構成し、機体の前後バランスを修正する技術が実
開昭５０−７２６２１号公報において既に提案されてい
る。Therefore, although it is a walking rice transplanter, the technology was developed in 1987-72621 to correct the longitudinal balance of the machine by configuring the running wheels that can change the height up and down so that they can also change the position forward and backward. This has already been proposed in the Publication No.

る。However, in the walk-behind rice transplanter shown here, the transmission case supporting the wheels, which can swing up and down, has a telescoping structure, and the transmission case expands and contracts to change the position of the wheels back and forth. Therefore, for example, when the transmission case faces diagonally downward, there is a problem in that the wheels change not only back and forth but also up and down. This problem is not only due to the difficulty in obtaining an appropriate front-back balance, but also when applied to a riding rice transplanter operated by a human on board, the problem lies in the repeated wheel position adjustment required to find the appropriate position. Then,
This has the disadvantage that the pilot feels extremely uncomfortable and anxious. Furthermore, since the operator manually rotates the screw shaft to extend and retract the transmission case, he or she must judge by feel whether or not the aircraft's longitudinal balance is in the proper state. The disadvantage is that it is difficult to obtain The present invention takes this situation into consideration, and aims to provide a rice transplanter that can rationally maintain the longitudinal balance of the machine body.
本発明は次の点を構成上の特徴とする。The present invention has the following structural features.

でき、前に述べたような前後位置調節に伴う不必要な上
下高さ位置の変化は全く生じない。That is, in the rice transplanter described at the beginning of the detailed description of the invention, the frame that swingably supports the transmission case of the wheel is configured to be horizontally movable in the longitudinal direction with respect to the main machine, and The vehicle is characterized by being provided with a longitudinal automatic adjustment mechanism that adjusts the longitudinal balance of the aircraft body by changing the position of the wheels longitudinally so that the ground pressure of the float is constant based on the detection result of the ground pressure of the float. . With this configuration, if the front-to-back balance of the rice transplanter fluctuates due to unavoidable reasons when using the rice transplanter, such as a change of operator, the entire transmission case that supports the wheels can be moved horizontally in parallel, and the transmission case can be moved in parallel. Regardless of the posture, the balance can be corrected while keeping the height position of the wheel relative to the main body constant, and unnecessary changes in the vertical height position associated with the front-back position adjustment described above will not occur at all. .

から、常に適・正な前後バランスが得られる。Therefore, the front-to-back balance of the machine can be quickly stabilized, and problems such as deep or shallow planting, floating seedlings, and mud pushing by the float caused by the float of the planting device sinking or rising can be prevented. Because the balance is corrected smoothly by maintaining a horizontal posture, the pilot does not feel uncomfortable or anxious. Furthermore, when changing the position of the wheels in the longitudinal direction, the ground pressure of the float is detected and automatically adjusted so that the ground pressure of the float remains constant, so that an appropriate longitudinal balance can always be obtained.

てある。In addition, when detecting the longitudinal balance, it is not based on the detection results of a body tilt detector such as a weight, but rather detects the ground pressure of one of the floats that supports the body between the wheels and the float. Since this is carried out based on the detection results, there is little chance of adverse effects from pitching of the aircraft. Next, an embodiment of the present invention will be described based on the drawings. Side b
