Description

[Detailed description of the invention] The present invention consists of a seedling tray that can be moved laterally, and a spare seedling tray that is fixedly held on the side of the machine at a position corresponding to a specific position in the horizontal movement path of the seedling tray. Regarding a rice transplanter equipped with.

This type of rice transplanter has a spare seedling tray fixed and held on the machine body side, so compared to the L7 model which has a spare seedling tray connected to the side of the seedling tray that moves laterally, even the preliminary seedling tray can be moved laterally. Reduces the collapse of the left and right balance of the aircraft due to movement (7)
This is advantageous in that it can improve the aircraft's maneuverability, but on the other hand, it has a spare seedling stand that is fixedly held on the aircraft side.
The relative position of the seedling tray, which moves laterally with respect to the machine body, must be accurately set at the appropriate target position for seedling supply, and it is troublesome to accurately control the stopping position of the seedling tray. Operation is required.

In order to eliminate this operational hassle, various structures have been proposed in the past that automatically stop the seedling stand in a fixed position, but these conventional seedling stand foot position stopping structures are In each case, contact sensing bodies are installed near the center of the machine in the left-right direction, and near the center of the back of the seedling stand in the left-right direction. Lateral movement and destination are configured to stop the operation of the planting device, so before putting the machine into the field or loading seedlings on the seedling rack, please set the center position of the seedling rack in advance. If you want to check whether the stop signal stops the lateral movement of the seedling bed or the drive of the planting device as expected, the seedling bed is automatically moved horizontally until it reaches the desired central position. The operator may have to wait for a relatively long time, or the operator may lean out from the side to get into the narrow space between the back of the seedling table and the rear of the machine, where various devices such as the mechanism for lifting and lowering the table and the transmission are complicated. They have to take the risk of operating the touch sensor on the aircraft side, and therefore, ordinary workers tend to skip pre-work inspections to avoid wasting time and performing dangerous operations. If the attachment device does not operate as expected or the seedling platform does not move horizontally and stop as expected, the machine that was used for planting in the field may be pulled up again from the field and adjusted. This may lead to inconvenient situations such as having to unload and adjust the seedlings that have been placed on the seedling stand even though there is a possibility that the seedlings may collapse.

The present invention maintains the spare seedling tray fixedly attached to the fuselage side [7], thereby maintaining good aircraft maneuverability, while also automating the stopping of the seedling tray that moves laterally in a fixed position for convenient use. The object of the present invention is to provide a rice transplanter having a structure that allows easy inspection of the automatically turned off device before starting work.

The rice transplanter according to the present invention is characterized by a rice transplanter that is equipped with a plurality of seedling placement parts and is configured to be able to move laterally, and a rice transplanter that is fixedly held on the machine body at a specific position along the seedling transfer route. In a rice transplanter that has a spare seedling stand, a protrusion is provided on the fixed part of the machine body, and the seedling stand is equipped with a seedling residue that detects when the amount of seedlings on the seedling stand has decreased below a certain level. A quantity detection switch and a position detection switch are provided, which detect the position by coming into contact with the protrusion and being pressed when the seedling stand reaches a certain position corresponding to the preliminary seedling stand. In addition, the remaining amount of seedlings detection switch and the position detection switch are provided with a mechanism that automatically cuts off power transmission to the lateral movement stop mechanism of the seedling stand and the planting device when both switches are activated. 7, and further characterized in that the position detection switch is attached to the seedling rest at a position closer to one end in the lateral movement direction of the seedling rest, This configuration provides the following effects.

That is, the remaining amount of seedlings detection switch and the position detection switch are associated with each other, so that when both of them are activated, a mechanism for stopping the lateral movement of the seedling stand and a mechanism for automatically cutting off power transmission to the planting device are activated. 7, so even though the spare seedling stand is fixedly held on the machine body side, the seedling stand is automatically moved to the appropriate position relative to the spare seedling stand at the appropriate time when seedlings need to be replenished. In particular, in the present invention, as a means for automatically stopping the seedling stand at a fixed position as described above, it is possible to conveniently perform seedling replenishment work by touching the protrusion 7. This uses a position detection switch that is suppressed, and the position detection switch is set on the seedling stand itself that moves laterally, and at a position closer to one end of the seedling stand in the horizontal movement direction. Therefore, before planting seedlings, it is necessary to check whether the lateral movement stop mechanism and the mechanism that automatically cuts off power to the planting device operate as expected in response to a stop signal when the seedling stand is in a fixed position. If you want to check whether the seedling tray is moving horizontally or not, you can simply reach out from the side and press the position detection switch located near one end of the seedling stand. Therefore, compared to the case where the aircraft is put into the field and the seedling planting work is carried out without such confirmation, it is possible to plant the seedlings after the seedling planting work has started. After discovering a malfunction in the equipment, it took a lot of effort to pull the machine out of the field, and after adjusting the malfunction, putting the machine back into the field and restarting the planting process caused the seedlings that had already been planted to be pushed over [7]. There is an advantage in that it is possible to avoid such inconveniences as the seedlings loaded on the seedling stand are once loaded in order to perform adjustment work, and then loaded again, which tends to cause collapse of the soil in the seedling bed.

In addition, since the position detection switch is attached to the seedling holder side rather than to the machine body, it is necessarily electrically connected to the seedling remaining quantity detection switch provided on the seedling holder side. In the case of interconnection, the wiring for the electrical interconnection can be summarized as simply as possible, such as by providing a position detection switch using a part of the wiring circuit leading from the machine body to the remaining seedling detection switch. But it is advantageous.

An actual case of the present invention will be explained below based on the drawings.

A plurality of seedling placement parts 1a and 1a are provided in an inclined position relative to the ground.
A seedling tray 1 comprising... is moved laterally and reciprocated, and in conjunction with the horizontal movement of the seedling tray 1, the lower ends of the seedling tray 1 and the placed seedlings are slidably supported. By cyclically operating the planting claw 4A of the planting device 4 between the seedling take-out port 9 formed on the fixed rail 8 and the leveled mud surface by the float 10, the placed seedlings are divided into planting unit quantities 7. This planting is carried out by the traveling device 5 of this machine A, which is equipped with wheels 5A that move on the tiller.
