Description

[Detailed description of the invention] [Field of industrial application] This invention connects a planting device equipped with a fertilization device to the rear end of the main body of the traveling machine, which is equipped with a driver's seat at the rear, via a link mechanism. The present invention relates to a rice transplanter with a fertilization device, in which a fertilizer storage tank of the fertilization device is arranged close to a planting arm of the planting device.

[Conventional technology]

Generally, in rice transplanters with a fertilization device, the fertilizer storage tank is placed close to the planting arm, which is located behind and below the driver's seat, so the fertilizer storage tank can be accessed from the driver's seat. If the distance to the input port is long and it is necessary to replenish fertilizer into the fertilizer storage tank during fertilization work, the operator must get off the machine and move to the rear of the rice transplanter before replenishing the fertilizer. Therefore, it was not possible to quickly replenish fertilizers.

Therefore, as a conventional technology to solve the above-mentioned inconvenience, a separate fertilizer storage tank is installed at the front of the aircraft to replenish the fertilizer storage tank, so that fertilizer can be replenished without getting off the driver's seat. (For example, Utility Model Application Publication No. 110225/1983).

[The problem that the idea attempts to solve]

However, in the conventional structure described above, the fertilizer transfer pipe from the fertilizer storage tank at the front of the aircraft to the fertilizer storage tank at the rear of the aircraft passes along the side of the seedling stand that moves back and forth from side to side, so the transfer route is a curved path. Furthermore, the transport distance becomes longer, and a powerful forced transport device such as a blower must be installed along the transport route, which increases the weight of the rice transplanter, which is desirable to reduce weight, and increases costs. There is.

An object of the present invention is to provide a device that can quickly replenish fertilizer while suppressing increases in weight and cost.

[Means to solve the problem]

A characteristic feature of the present invention is that the planting device is provided with a fertilizer input port connected in communication with the fertilizer storage tank at the top of the planting device.

[Function] By providing the fertilizer inlet of the fertilizer storage tank in the upper part of the planting device, the distance from the driver's seat to the fertilizer inlet can be shortened and fertilizer can be easily replenished.

In addition, the flow path from the fertilizer input port to the fertilizer storage tank can be formed in a straight line without being hindered by the horizontal movement of the seedling platform, and the relatively short conveyance distance can be achieved by utilizing natural flow. Easy to do smoothly.

[Effect of idea]

Therefore, by providing a fertilizer inlet at the top of the planting device, it is possible to replenish fertilizer while sitting in the driver's seat. This means that the process can be done more quickly than the one that moves backwards, and as a result, it has become possible to perform fertilization work with high efficiency.

Further, unlike the case where a fertilizer storage tank for replenishing the fertilizer storage tank at the rear of the aircraft body is provided in the front part of the aircraft body, the transport route is not lengthened, and an increase in weight and cost can be suppressed.

〔Example〕

FIG. 3 shows a riding rice transplanter equipped with a fertilization device S. This rice transplanter is equipped with an engine E and a transmission case M at the front of a traveling machine body equipped with front and rear wheels 1 and 2, and a driver's seat 3 at the rear of the traveling machine body.
In addition, a planting device A equipped with a fertilizing device S is connected to the rear end of the traveling body via a link mechanism 4.

To explain the planting device A in detail, as shown in FIG. A seedling stand 10 on which pine-shaped seedlings are placed is provided so as to be able to slide back and forth in the lateral direction in conjunction with the vertical movement of the planting arm 6. Seedlings are cut out one by one using a planting claw 5 and planted in the field.

The fertilizer application device S includes a fertilizer storage tank 11 disposed close to the planting arm 6, a feeding mechanism 12 connected below the fertilizer storage tank 11, and a flow pipe below the feeding mechanism 12. It consists of a groove creator 14 connected via a groove maker 13. The feeding mechanism 12 includes a cylindrical feeding case 12A connected to the lower part of the tank 11;
It consists of a feeding roll 12B provided in this feeding case 12A, and said feeding roll 12B.
The drive rotation shaft 12b and the first link mechanism 8 are interlocked and connected by the second link mechanism 9, so that the fertilizer can be dropped and supplied into the groove formed by the groove cutter 14.

A fertilizer inlet 15 is provided on the top of the planting device A and is connected to the fertilizer storage tank 11 through two hose parts 15A, 15A, so that the fertilizer can be supplied to the fertilizer storage tank 11. It is designed so that you can do it while staying in the driver's seat 3.

To explain in detail the mounting structure of the fertilizer input port 15, as shown in FIGS.
A support shaft 17 is installed across the support arms 16, 16, and the lower part of the fertilizer inlet 15 is slidably attached to the support shaft 17 via a bracket 18. The lower ends of the hose portions 15A and 15A of the fertilizer input port 15 are connected to the long holes 11A and 11A formed in the fertilizer storage tank 11, respectively.
11A separately, and the hose part 1
A horizontally long plate member 19 that is inserted through the lower end portions of the fertilizer storage tank 11 is slidably inserted into a pair of guide portions 11B and 11B that are U-shaped in cross section and formed on the upper surface of the fertilizer storage tank 11. By fitting and holding the fertilizer inlet 15 and sliding it left and right, the hose parts 15A and 15A are connected to the elongated holes 11A and 11.
It is moved within A so that the fertilizer storage tank 11 can be uniformly replenished with fertilizer. Note that 20 shown in the figure is a bolt with a knob for fixing the fertilizer input port 15 to the support shaft 17.

When feeding fertilizer to the fertilizer input port 15, as shown in FIG. After pulling it out, the fertilizer is supplied to the fertilizer input port 15 on the rear side of the machine. Furthermore, when supplying fertilizer to the fertilizer input port 15,
The lid body 23 provided at the upper part of the fertilizer input port 15 and capable of swinging open and close is kept open.

[Another example]

In the embodiment described above, one fertilizer input port 15 was provided, but two or more may be provided.

Further, in the embodiment described above, the fertilizer input port 15 is configured to be movable from side to side, but it may be fixedly installed above the seedling stand 10.

Further, in the embodiment described above, the fertilizer input port 15 is attached to the seedling stand 10, but it may be attached to a support member extending from the machine body side.
