Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a riding-type rice transplanter that is capable of fertilizing and spraying herbicides at the same time as planting seedlings.

[Conventional technology]

A rice transplanter capable of fertilizing and spraying herbicides at the same time as planting seedlings is disclosed, for example, in Japanese Utility Model Application Publication No. 153192/1983.
A walking rice transplanter has been proposed that has a structure that sprays herbicide laterally from the machine body and then sprays it from above the seedlings that were planted in the previous process.

[Problem that the invention attempts to solve]

Spraying the chemical from above the planted seedlings prevents the chemical from coming into direct contact with the roots of the planted seedlings, and also ensures that a dissolved film of the chemical is formed on the water surface of the field around the planted seedlings. Because the chemical is sprayed laterally, it is difficult to spread the chemical evenly over a wide area from near to far away from the machine.Especially, the rice transplanter with a larger number of planting rows has a wider spray width, so it is difficult to spread the drug evenly over a wide area. is expected to become even more difficult.

The present invention is configured to allow fertilization and herbicide spraying to be carried out using a riding-type rice transplanter, and by making improvements to the arrangement of the fertilizer and herbicide spraying equipment, it is possible to avoid any negative impact on the planted seedlings. The purpose is to enable uniform and good herbicide spraying.

[Means for solving problems]

In order to achieve the above object, the riding-type rice transplanter of the present invention is a riding-type rice transplanter in which a seedling planting device equipped with a seedling stand tilted forward is connected to the rear of the vehicle body so as to be movable up and down. A fertilizer application device and a herbicide spraying device are arranged behind the herbicide spraying device, with the fertilization device positioned in front of the herbicide spraying device, and between the fertilization device and the herbicide spraying device, The structure is equipped with a scattering prevention body that prevents the agent from scattering forward.

[Function] According to the above configuration, the herbicide is taken out from the lower end of the seedling stand and sprayed from above the seedlings after being planted, and dissolves on the water surface and spreads in a film. and,
Even if some of the herbicide sprayed from above scatters to the seedling planting position in front, it is blocked by the scattering prevention body, and the herbicide scatters to the roots of the seedlings before they are pushed into the field. adhesion is prevented.

In this case, the herbicide spraying device is located at the rear of the fertilization device, that is, the farthest back from the seedling planting position near the bottom of the seedling stand, so for example, the herbicide spraying device is placed in front of the fertilization device. It is difficult for the scattered herbicide to reach the seedling planting position compared to the case where the seedlings are planted.
The ability of the anti-scattering body to prevent herbicides from adhering to the roots of seedlings is more effectively demonstrated.

[Effect of idea]

Therefore, according to the present invention, the fertilizer application device and the herbicide spraying device are rationally arranged behind the seedling stand, and a scattering prevention body is introduced, so that the herbicide adheres to the roots of the seedlings during planting. We were able to construct a riding-type rice transplanter that can effectively apply fertilizer and spray herbicides without any problems.

〔Example〕

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

FIG. 1 shows the rear part of a riding type rice transplanter for herbicide spraying in which a seedling planting device A and a herbicide spraying device 30 are attached to the rear part of the riding vehicle body via a link mechanism 13 so as to be able to move up and down. ing.

The seedling planting device A includes a seedling planting mechanism 1 in a planting transmission case 9 extending rearward from a planting case 8.
0, and a seedling stand 1 in a forward tilted position that is reciprocated in the lateral direction of the machine in conjunction with the rocking drive of the seedling planting mechanism 10, and a soil leveling float 2 is pivotally attached to the lower part of the planting transmission case 9. The fertilizer application device 3 and the herbicide spraying device 30 are arranged behind the seedling stand 1, and the fertilizer application device 3 is connected to the herbicide spraying device 30.
It is located in front of the

The seedling planting mechanism 10 connects a swinging arm 12 to a planting transmission case 9 so as to be able to swing freely, a planting arm 11 is provided at the tip of the swinging arm 12, and the seedling planting mechanism 10 connects a swinging arm 12 to a planting transmission case 9 so as to be able to swing freely. It is configured by providing an attached claw 19, and the tip of this planting claw 19 is attached to the seedling stand 1.
The vehicle rotates between the take-out port formed at the lower end and the field, and as the vehicle advances, the lower end of the pine-shaped seedlings placed on the seedling stand 1 is cut off and planted in the field. I'm starting to wear it.

As shown in FIGS. 1 and 2, the fertilizer application device 3 includes a hopper 14 for storing fertilizer, a feeding case 6 connected to the lower part of the hopper 14, and a dispensing case 6 disposed within the case 6. A hose 20 is attached to the lower end of the case 6 to guide the fertilizer, and a groove cutter 4 is attached to the lower end of the hose 20. The feed roll 18 is fixed to a drive rotation shaft 15 that is rotatably supported by the feed case 6, and the fertilizer filled in the feed recess 17 formed on the periphery of the feed roll 18 is transferred to the seedling planting mechanism. 10, the drive rotation shaft 15 is rotationally driven via the swing arm 31 and the rod 21, so that the drive shaft 15 is dropped into the case 6. In addition, 22 in the figure is a brush that scrapes off the seeds inside the roll 18.

The herbicide spraying device 30 includes a hopper 34 for storing the herbicide, a feeding case 35 connected to the lower part of the hopper 34, a roll 38 disposed inside the case 35, and the like. ing. An arm 33 connected to the roll rotation shaft via a connecting rod 32 is interlocked with a swinging arm 31 fixed to the link mechanism 13, and is connected to the seedling planting device A and the fertilizing device 3. The roll 38 is reciprocatingly rotated in synchronization, and the case 3
5 The herbicide is sprayed onto the field through the opening at the bottom. Further, at the rear end of the mounting member 36 extending rearward from the herbicide spraying device 30, a brush 37 for brushing off the herbicide adhering to the planted seedlings is planted so as to face downward.

Furthermore, as shown in FIG. 1, a film-like scattering prevention body 39 is hung from the lower part of the case 35 between the herbicide spraying device 30 and the fertilizer application device 3. This prevents the sprayed herbicide from scattering toward the front of the vehicle. This anti-scattering body 39 is extended to a position close to the ground leveling float 2, and prevents the sprayed herbicide from scattering toward the seedling planting mechanism 10 side, and weeds the roots of the seedlings that are in the middle of being planted in the air. Prevents the agent from adhering.

In the above embodiment, the brush 37 is attached to the mounting member 3.
Although the brush 37 is fixed to the rear part of the mounting member 36, the brush 37 may be formed into a cylindrical shape and fitted freely around a support shaft horizontally suspended at the rear end of the mounting member 36.
It may be configured so that the tip of 7 comes into contact with the planted seedlings and automatically rotates as the vehicle moves forward.
Furthermore, this brush may be driven and rotated by a transmission motor or the like. Further, a skirt may be provided at the bottom of the case 35 to concentrate the herbicide.
