Description

[Detailed description of the invention] This invention relates to a rice transplanter with a fertilization device that can perform fertilization work at the same time as seedling planting work. This invention relates to a tube that guides and supplies fertilizer to a location and is equipped with a fertilizer delivery device that delivers fertilizer.

In such rice transplanters, there is a risk that the fertilizer remaining in the sub-tank will become moist and solidify, causing problems in transporting the fertilizer during the next operation, so it is necessary to remove the remaining fertilizer in the sub-tank at the end of the operation. be. For this reason, in the past, the top cover of the sub-tank was removed and the sub-tank was taken out from above, but in this case, not only was it a time-consuming and cumbersome task, but also the fertilizer dispensing device at the bottom was able to remove the fertilizer from the vicinity. There was an inconvenience in that it was difficult to remove the fertilizer properly because it was difficult to put one's hand in the vicinity of the fertilizer delivery tool.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to easily and quickly remove the fertilizer remaining in the sub-tank by simply modifying the mounting structure for the sub-tank. be able to do so, and regardless of that,
It is an object of the present invention to make it possible to easily and quickly fix a sub-tank in a position of use.

The characteristic configuration of the present invention is that, in the above-mentioned rice transplanter with a fertilizing device, the sub-tank is pivotably supported vertically so that the sub-tank can be switched to a fertilizer take-out position located lower toward the top opening side. The pivot part is provided with a flexible part that allows parallel vertical movement of the sub-tank, and a stopper that abuts and supports the sub-tank in a state where it is lowered along the flexible part so as not to swing toward the fertilizer removal position. is provided so as to be able to be switched to a non-operating state as the sub-tank is raised along the flexible portion.

In other words, since the sub-tank can be swung to the fertilizer removal position where the upper opening is located downward, the remaining fertilizer in the sub-tank is transferred to the fertilizer located near the feeding rotary tool as the sub-tank is swung. It is possible to take out the remaining fertilizer in the sub-tank at the same time by allowing it to fall under its own weight. This can now be done easily and quickly with the simple operation of swinging it.

In particular, according to the present invention, in order to support the sub-tank so that it can swing, the sub-tank can be moved up and down in parallel, and a stopper that acts when the sub-tank is in the lowered state is provided to effectively utilize the sub-tank's own gravity. However, since the sub-tank can be securely fixed so that it cannot be swung toward the fertilizer removal position, special tools or the like are required to fix the sub-tank in the operating position while allowing the sub-tank to swing for fertilizer removal. This can be done easily and quickly by simply moving the sub-tank up and down.

As a result, we have achieved a rice transplanter with a fertilization device that can be used even better overall.

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 steering wheels 1, 1 and a pair of left and right rear wheels 2, 2 are provided so as to be freely drivable, and a spare seedling stand 3 is provided at the front of the vehicle body.
and a driver's seat 4 is provided at the rear of the vehicle body to form a passenger vehicle body, and the ground is leveled on a float 7 by a planting claw 6 that sequentially takes out seedlings one by one from a seedling stand 5. A seedling planting device 8 for planting seedlings on a muddy surface is connected to the rear of the passenger vehicle body by a hydraulic cylinder 9 so that it can be raised and lowered, and is further guided from a main tank 10 provided above the driver's seat 4. tube 11
A rice planting device equipped with a fertilization device 12 is provided to supply powdered and granular fertilizer to the side of the planted seedlings by dropping it under its own weight through a fertilization device 12, which performs fertilization work at the same time as planting seedlings as the vehicle advances. The machine has been configured.

The support frame 10A of the main tank 10 is connected and supported to the support column 3A of the preliminary seedling stand 3 via a leg rod 13. Moreover, as shown in FIG.
4A can be attached, and a large amount of spare seedlings can be placed there as needed.

To explain the fertilizer application device 12, as shown in FIG. 3, a groove cutting device 15 which has a boat-like shape in plan view and is open at the bottom and rear and which also serves as a fertilizer release guide is supported by the float 7. Let me set it up,
Fertilization grooves U are configured to be formed on the lateral sides of the planted seedlings, and a fertilizer guide supply device is connected to the sub-tank 16 that stores the powdery fertilizer from the main tank 10 and is connected to the groove-cultivator 15. Rotating body 1 as a feeding device that feeds out fertilizer in fixed amounts toward the pipe 17
8, so that fertilizer can be sequentially supplied into the fertilization groove U.

The upper lid 16A to which the guide tube 11 is connected,
The main tank 10 is provided with a shutter 19 which is detachably attached to the upper opening S of the sub-tank 16 and which opens and closes the discharge part of the main tank 10.
As shown in FIGS. 4 and 5, a horizontal shaft-shaped pivot pin 22 that pivotally supports the vertical frame 20 connected to the sub-tank 16 in a vertically swingable manner is attached to the frame on the seedling planting device 8 side. The sub-tank 16 is supported by a U-shaped bracket 21A attached to the holder 21, and the sub-tank 16 is pivoted so as to be vertically swingable in order to be able to switch the sub-tank 16 to the fertilizer removal position located lower toward the upper opening S side. The pivot pin 22 is formed on the sub-tank side vertical frame 20 and forms the supporting pivot portion A.
The insertion hole 23 is formed in the shape of a long hole extending in the vertical direction as a flexible portion that allows parallel vertical movement of the sub-tank 16.
In order to abut and support the fertilizer retrieval position in a state in which it is lowered along the direction, a stopper 24 is provided that abuts against one side of the sub-tank side vertical frame 20 when viewed in the direction of the sub-tank swing axis. , sub tank 1
6 is formed on the inner surface of the U-shaped bracket 21A in a state in which it is switched to a non-operating state as it is raised along the insertion hole 23, and the fertilizer in the sub-tank 16 can be taken out at the end of the work. , the sub-tank 16 is configured to be able to be easily operated by simply swinging the sub-tank 16 downward, and furthermore, the sub-tank 16 can be fixed in a desired usage posture by simply moving the sub-tank 16 up and down in parallel. It's like this.

However, the range of swinging of the sub-tank 16 toward the usage position is restricted by its lower end being received by a horizontal rod 25 supported on the upper part of the supply pipe 17. Further, the feeding rotary body 18 is driven in conjunction with the planting claw 6, and this interlocking mechanism is released when the sub-tank 16 is operated to swing.

Next, another example will be described.

In FIG. 6, the insertion hole 23 is formed in the shape of a long hole extending in the vertical direction, and the lower end thereof is positioned closer to the stopper 24 side.

In carrying out the present invention, the specific structure of the pivot for the sub-tank 16 can be modified in various ways, and
Depending on the specific structure of the pivot portion A, the specific structure of the flexible portion 16 can also be changed in various ways.

In addition, the present invention can be applied to a walking rice transplanter as well as a riding rice transplanter.
