Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rice transplanter with a fertilization device, which has a fertilization device installed on a traveling machine body provided with a seedling planting device.

[Conventional technology]

Conventionally, when installing a fertilizing device in the rice transplanter mentioned above, fertilizer is applied continuously to the area where seedlings are planned to be planted by the seedling planting device, or to an intermediate position between adjacent seedling planting areas in the left and right direction of the machine body, or by applying fertilizer to the planting claw of the rice transplanter. There was a case where fertilizer was applied to the planted seedlings in the left and right direction of the aircraft, even though they were separated in the direction of aircraft travel.

However, if the aircraft travel direction changes and meandering occurs, seedlings may be planted in the fertilized area or fertilized close to the planted seedlings, causing the fertilizer to wither and cause plant defects. There was a drawback that planted seedlings were scraped off by the furrower that constituted the fertilization device, resulting in missing plants.

Therefore, as shown in Japanese Utility Model Application No. 51-60414, for example, in order to avoid the negative effects caused by meandering of the machine, a groove cutter is provided close to the planting claw in the left and right direction of the machine, and An intermittent supply mechanism is installed to supply the chemical so that the chemical is applied to the intermediate position between adjacent planting sites in the direction, so that the chemical is applied near the planted seedlings at almost the same time as the seedlings are planted, regardless of the meandering. I have to.

[The problem that the idea aims to solve]

In this case, since it is a mechanism that applies chemicals, there is no disadvantage that the muddy soil washed away by the furrower flows into the planted seedlings and tends to knock over the planted seedlings, as in the case of fertilization. The drug supply pipe must be installed in such a way that it does not interfere with the rotation trajectory of the planting claw or the lateral movement of the seedling stand, which has the disadvantage of making it difficult to manufacture, and the need to replenish seedlings during planting. In some cases, the chemicals that have been applied intermittently reach the seedling stand, so the mud pushed out at that time pushes the chemicals toward the already planted seedlings, causing the chemicals to come into contact with the seedlings. Problems arose, and this problem, which also led to fertilizer withering, remained unresolved.

In view of the above points, it is an object of the present invention to make it possible to prevent seedlings from falling due to fertilizer failure without causing the planting seedlings to collapse using the furrower or causing manufacturing difficulties.

[Means to solve the problem]

In order to achieve the above object, the present invention provides the above-mentioned rice transplanter with a fertilizing device, in which the fertilizing device is provided at a position apart from the planting claw of the seedling planting device in the forward direction of the machine body, and A device, in conjunction with the seedling planting device, fertilizes an intermediate position between the adjacent seedling planting sites on or near a line connecting adjacent seedling planting sites in the front and back of the aircraft traveling direction. The present invention is characterized in that it is equipped with an intermittent supply mechanism for supplying fertilizer in such a manner.

[Effect]

The effects of the above configuration are as follows.

In other words, before planting the seedlings, a groove is created on the mud surface, and after planting the seedling, a groove is placed between the planted seedlings on or near the line connecting the adjacent planted seedlings in the machine traveling direction. Fertilize the waxed areas intermittently.

[Effect of idea]

The effects of the above action are as follows.

In other words, by installing the fertilizing device apart from the planting claws, the furrower can be installed without being restricted by the planting claws or their rotation locus, making it easy to manufacture, and making it easier to push the furrower with the furrower. It is possible to reliably avoid knocking down the planted seedlings due to washed away mud, and even if the meandering occurs as the aircraft travels, the planting claws will be moved further to the left and right of the aircraft than the expected position when traveling in a straight line. Even if there is a deviation, the planting claw can be positioned in the gap in the direction of movement of the aircraft that is intermittently supplied with fertilizer, that is, in the area where fertilizer is not being supplied, and the seedlings can be planted there.
It is now possible to prevent missing plants due to fertilizer withering.

Furthermore, the area between the planting rows where workers walk when replenishing seedlings is not the target position for fertilizing seedlings immediately after planting, so even if workers walk between the planting rows, , there is less stepping near the fertilizing position, and the walking point is far from the planted seedlings and fertilizing position, so even if some mud is pushed out by walking, the effect of mud movement is less than before. Therefore, it is less likely that the fertilizer will wither due to the fertilizer coming close to the already planted seedlings due to the falling of the already planted seedlings or movement of the fertilizer.

As described above, by applying fertilizer in advance and setting the fertilizer application position on or near the line, two effects can be achieved: easing the arrangement of equipment and effectively suppressing fertilizer withering. I was able to satisfy myself.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to illustrative drawings.

A driving body with wheels 1 and 2 mounted on the front and rear wheels is provided with a driver's seat 3 and a handle 4, a spare seedling loading section 5 in the front, and first and second tanks 6, 7 for fast-release fertilizer and slow-release fertilizer. At the same time, a seedling planting device 9 is interlocked and connected to the rear via a link mechanism 8, and a first fertilizing device 10 for fast-release fertilizer and a second fertilizing device for slow-release fertilizer are connected to the seedling planting device 9. 1

The groove creators 18 are provided at a distance from the planting claws 20 toward the front of the machine body, and are positioned on a straight line passing through each of the planting claws 20 in the longitudinal direction of the machine body. In the figure, 18a indicates a backfilling board.

A pair of fertilizer storage grooves 22, 22 are formed on the outer circumferential surface of the feed roll 21 provided at the lower part of the first hopper 13, with a phase difference of 120 degrees in the circumferential direction. The drive system for the planting claw 20 is interlocked and connected so that the feed roll 21 rotates 1/3 with one rotation of the planting claw 20, and the length of the downstream hose 19... , and the positions of the furrowers 18 are arranged so that the fed fertilizer is supplied between adjacent seedling planting locations a in the machine traveling direction, thereby forming an intermittent supply mechanism. .

To configure this intermittent supply mechanism, for example, the first
A shutter may be provided at the lower part of the hopper 13 or in the middle of the downstream hose 19, and the shutter may be opened and closed in conjunction with the driving of the planting claws 20.
