Description

[Detailed description of the invention] The present invention relates to a rice transplanter equipped with a fertilization device that can perform fertilization work while planting seedlings, and more specifically, the seedling planting device is provided so that it can be moved up and down relative to the vehicle body, and It relates to a tank equipped with a tank for storing powdery fertilizer to be supplied to fields.

In such a rice transplanter, conventionally, the fertilizer tank is configured such that the bottom wall thereof is tilted downward toward the discharge port, so that the fertilizer in the tank can be sent to the discharge port. If you try to store a large amount of fertilizer, the height of the tank will increase, so if the tank is installed in front of the driver's seat, for example, it will obstruct the operator's view, and it will also be difficult to operate the tank. When installed near the seats, there were disadvantages such as interfering with the seedling replenishment work for the seedling planting device.

For this purpose, as shown in FIG. 5, for example, a spiral body 32 that conveys the fertilizer to the side of the discharge port 31 is provided in the tank 33, and a spiral body 32 that conveys the fertilizer to the side of the discharge port 31 is provided in the tank 33. A pinion 35 for the rack 34 that slides is attached to the spiral body 32 via a one-way rotation clutch mechanism 37 so that it rotates together with the spiral body 32 only when the rack 34 is driven and rotated by the movement of the rack 34 as the seedling planting device rises. The present inventor had previously thought of a means, but this means was difficult to put into practical use because of its complicated structure and high cost.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to store a large amount of fertilizer while reducing the height by making effective use of the original structure and making simple modifications to the tank support structure. The purpose of the present invention is to provide a tank in such a state that it is possible to take out the fertilizer without fail, and in addition, in a state that does not require any special operation for this purpose.

The present invention is based on the above-mentioned rice transplanter with a fertilization device.
The fertilizer storage tank is pivotally supported so as to be able to freely switch to an inclined position in which the bottom wall of the tank is positioned at a lower end of the discharge port, and the fertilizer storage tank is switched to the inclined position when raised as the seedling planting device ascends and descends. A mechanical linkage mechanism for swinging the tank is provided between the tank and the seedling planting device side member.

Next, the effects of the characteristic configuration of the present invention will be described.

In other words, by pivoting the fertilizer tank to an inclined position with the bottom wall of the tank positioned so that the discharge port is at a much lower level, it is possible to store a large amount of fertilizer while maintaining a low height under normal conditions. At the same time, it has become possible to switch to an inclined position at the appropriate time to send the fertilizer to the discharge port side, thereby making it possible to reliably take out the fertilizer from the tank.

In particular, according to the present invention, when planting seedlings with the seedling planting device lowered, good forward visibility is required because it is necessary to move the aircraft along a desired route, and the seedlings are planted with respect to the seedling planting device. Although it is required to position the tank low so that it does not get in the way for replenishment, it is important to note that the above requirements do not exist during non-planting work when the seedling planting device is raised, and to make effective use of this fact. A mechanical linkage mechanism is provided between the tank and the seedling planting device side member for swinging the tank so as to switch the tank to the tilted position when the seedling planting device goes up and down as the seedling planting device goes up and down. Therefore, with a simple structure that rationally utilizes the original configuration in which the seedling planting device is raised and lowered relative to the vehicle, it was possible to avoid special operations on the tank.

As a result, a rice transplanter with a fertilization device that can be used more conveniently as a whole has been obtained.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, a pair of left and right front wheels 1, 1,
At the rear of a passenger vehicle body equipped with a pair of left and right rear wheels 2, 2, a driver's seat 3, etc., there is a slanted seedling stand 4 that moves back and forth laterally with a constant stroke, and a pine-shaped seedling W placed on it is placed at the rear of the vehicle body. A seedling planting device 7 equipped with a plurality of planting claws 5 for taking out and planting seedlings one by one, and a plurality of floats 6 for leveling the muddy surface is connected via upper and lower rocking tanks 8a and 8b. Connected so that it can be raised and lowered,
Furthermore, a hydraulic cylinder 9 for raising and lowering the seedling planting device is provided to constitute a riding type rice transplanter.

As shown in FIGS. 2 and 3, a groove making device 10 which also serves as a fertilizer release tool and which forms a groove U for fertilization on the lateral side of the seedling planting location by each of the planting claws 5 is used for planting seedlings. A ground leveling plate 11 is connected to and supported by the device 7 and is attached to the trencher 11 to fill the groove U after fertilizer is supplied. A tank 12 having a U-shape in plan view for storing powdery fertilizer to be supplied to each of the trenchers 11 is provided in the vehicle body surrounding the driver's seat 3, and a concave groove 13a for entering the fertilizer is provided around the periphery. The formed rotating body 13 for feeding out fertilizer
are provided at each of the left and right pair of discharge ports 12a, 12a formed at the rear end side of the tank 12, and a hose 14 is provided to connect each discharge port 12a and each groove cutter 10. The structure is designed so that fertilization can be done simultaneously with seedling planting as the process progresses.

As shown in FIG. 3, the fertilizer tank 12 is
The rear end is pivotally supported around the horizontal axis A link 15 is provided between the swinging link 8a and the tank 12, and the link 15 moves up integrally with the upper swinging link 8a to press and swing the tank 12. The tank 12 is configured to be able to be swung into a tilted position.

In short, during planting work, the tank 12 is positioned low so that it does not interfere with the seedling replenishment work to the seedling planting device 7, and after one process is completed, the seedling planting device 7 is raised to move on to the next process. When traveling on a headland, the tank 12 is swung to an inclined position so that the fertilizer in the tank can be sent to the discharge port 12a side.

In the figure, 16 indicates that the fertilizer in the tank 12 is at the discharge port 1.
It is a receiving plate that prevents the flow from flowing backward in the direction away from the tank 2a, and is provided in a protruding manner on the tank bottom wall 12A.

In addition, in carrying out the present invention, instead of the link 15, for example, as shown in FIG. 4, a wire 17 for pulling the tank 12 may be provided between the upper swinging link 8a and the tank 12. , these are collectively referred to as mechanical linkage mechanisms.

Further, the position of the tank 12 can be changed in various ways, such as placing it in front of the driver's seat 3, and the structure for conveying the fertilizer from the tank 12 to the mud surface can be changed, for example, by using compressed air. Various changes can be made, such as forcing the vehicle to be transported.
