Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to plant crop seedlings such as wheat placed on a seedling platform while traveling in the field in a field scene by a planting claw planting operation. The present invention relates to the seedling planting device.

[Conventional technology]

In the conventional wheat cultivation, it was a general method to sow seed wheat in a field and grow it. However, in such a method, the seeding density of the seed mud becomes high, so that the growth of the lived mud is hindered and it becomes vulnerable to pests and diseases, and therefore it is not possible to expect an increase in the yield. Therefore, in the case of wheat cultivation, a method of planting seedlings that have been raised in advance in the field, such as rice cultivation, has been proposed, but the place for planting wheat seedlings is different from the paddy field, because it is a place with low moisture and hard soil. With conventional nails consisting of peaks and forks, when the seedlings were held, the bed soil part adhered to the beaks and forks, making it difficult to separate them. When the artificial nails forcefully plant the seedlings in the soil, there is a problem that the root part is directly damaged by the impact from the hard soil.

[Problems to be solved by the present invention]

The present invention has been made in view of the above circumstances in order to solve these problems, and it is a planting nail that transplants wheat seedlings with a conventional planting nail consisting of beak and fork. The retained seedlings can be easily separated, and when planting the seedlings in the soil, the roots of the seedlings are not directly damaged by the impact from the soil and the seedlings are smooth and water-free and hard. It is an object of the present invention to provide a seedling planting device that can be planted in soil.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the technical means taken by the present invention is to scrape crop seedlings such as wheat seeds placed on a seedling placement table by uniting planting claws by scraping for each unit planting plant. In a seedling planting device adapted to be planted on a surface, a spray nozzle for spraying a liquid on the planting claw is provided so as to face the operation locus of the planting claw, and a spray is provided on the front surface in the traveling direction of the spray nozzle. A hole forming plate for forming a seedling planting hole is provided below the nozzle.

[Function of device]

Therefore, according to the present invention, the planting claws that are planted and operated can plant the seedlings scraped from the seedling platform for each unit planting plant in the field scene. Then, water, fertilizer water, and other liquids are jetted from the spray nozzles that are provided so as to face the operation locus to the planting claws that are planted, so that the seedlings scraped from the seedling mounting table and held are removed from the planting claws. Easily separated and planted in the field. on the other hand,
The hole forming plate provided on the front surface in the traveling direction of the injection nozzle,
As the machine progresses, a seedling planting hole is formed below the spray nozzle, and the sprayed liquid flows into this seedling planting hole to soften the soil, so the root part of the seedlings of wheat planted to be planted is hard. It can be planted smoothly in the planting hole without being damaged by the impact directly from the soil.

〔Example〕

Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
Reference numeral 1 denotes a traveling machine body of the seedling planting device, which is provided with a front wheel 2 and a rear wheel 3, and behind a machine body frame 5 provided with a driving operation section 4, a planting section 7 that slides in a field scene by a float 6. It is mounted so that it can be raised and lowered. Reference numeral 8 denotes a front-to-back and low-height seedling mounting table obliquely provided in the planting section 7, and 9 denotes a planting claw, which is a planting claw 9
Is formed by attaching a beak 14 and a fork 15 to the tip of a planter arm 13 supported by a planter case 12 via link mechanisms 10 and 11. Then, the planting claws 9 rotate up and down along the operation locus A shown in FIG. 1, and the seedlings placed on the seedling placing table 8 are removed from the scraping groove provided on the apron 16 at the upper moving position. Each unit planting stock is scraped and held, and then the forks 15 push out the seedlings a and plant them at the lower position where the beak 14 plunges into the soil.

Reference numeral 17 denotes an injection nozzle for injecting water or a liquid such as fertilizer having a low concentration, which is connected to a liquid tank 18 mounted on the machine body frame 5 via a transportation pipe 19,
The injection port 17a of the injection nozzle 17 facing the operation locus A of the planting claw 9 opens toward the 14 beaks of the planting claw 9 that has descended.

A plate-shaped hole forming plate 20 is integrally attached and fixed to the front surface of the injection nozzle 17 in the traveling direction, and the lower end portion of the hole forming plate 20 is located below the lower surface of the injection nozzle 17. Thus, when the machine is running, the hole forming plate 20 that has penetrated into the soil width can form the seedling planting groove b below the spray nozzle 17. Reference numeral 21 is a liquid pressure pump, and 22 is an opening / closing valve.

Further, although FIG. 1 shows that the injection nozzle 17 opens toward the lowered position of the planting claw 9, the present invention is not limited to this. It is only necessary that the liquid can be ejected toward the planting claw 9 facing A. Further, as shown in FIG. 4, an injection nozzle 23 is provided behind the planting claw 9, or as shown in FIG.
The injection nozzle 24 may be provided so as to face rearward and upward of the planting locus A, and the liquid may be jetted from behind toward the rising planting claw 9 after planting the seedlings.

FIG. 7 to FIG. 9 show a soil gathering plate for improving the planting posture of seedlings, and have a U-shaped cross section having slanted soil gathering portions 25 at both ends at the link fulcrum portion of the planter arm 13. A soil-draining plate 26 is attached and fixed to the planter arm 13 via mounting bolts 27 so that the soil-draining plate 26 is reciprocally moved together with the planter arm 13 to pull soil on both sides of the planted seedling.

Further, FIG. 10 shows the planting claw 9 provided with a protective cover for covering the rear surface of the fork 15. That is, a protective cover 2 having a V-shaped rear surface having a pointed portion below
8 is fastened together with the mounting bolt 29 of the peak 14, and a notch 31 that contacts the pin 30 of the beak 14 is formed below the bolt 8.

Further, in FIG. 13, the intermittent valve 3 synchronized with the operation of the planter arm 13 is provided in the liquid transport path of the injection nozzle 17.
2 is provided so that the liquid can be jetted with a strong water pressure only when the beak 14 and the fork 15 reach the vicinity of the jet nozzle 17. Further, FIG. 15 shows that the ejection port 17a of the ejection nozzle 17 has a fan-shaped peak 14
This shows that the soil removal effect of the fork 15 is further increased.

In the above-mentioned configuration, when the seedlings are placed on the seedling mounting table 8 and run in the field, the planting claws 9 that rotate up and down along the operation locus A are moved from the seedling mounting table 8 to the unit planting stock. The seedlings can be scraped off for each and planted in the field in the down position. Then, water or a fertilizer having a low concentration is sprayed toward the striations of the beak 14 from the spray nozzle 17 that opens to face the operation locus A from scraping the seedling to the field scene. Since the soil can be improved and the soil is supplied with water, the retained shoots can be easily separated from the planting claws 9 and planted in the field scene. On the other hand, since the hole forming plate 20 is attached and fixed to the front surface of the injection nozzle 17 in the traveling direction, the injection nozzle 17 is not damaged due to an excessive force applied thereto as the machine body advances, and the injection nozzle 17 can be smoothly moved. It is possible to form a groove b for planting seedlings. Since the liquid sprayed from the spray nozzle 17 flows into the seedling planting groove b to soften the soil, the root portion of the seedling is not directly damaged by the hard soil and damaged, and the seedling planting is smoothly performed. Groove b
Can be implanted in. Further, in the case where the liquid is sprayed from the rear of the rising planting claw 9, the mud adhered to the back surfaces of the beak 14 and the fork 15 is completely washed away, so that the seedlings on the seedling mounting table 8 are cut and scraped appropriately. In addition, the seedlings held by the beak 14 and the forks 15 to which the liquid adheres can be easily separated from the planting claws 9 and can be planted smoothly without having to carry around.

In the case where the earth moving plate 26 is provided, the planting holes are closed from the left and right after planting the seedlings, so that even the planted seedling a planted in a place with a low water content can always be kept in an appropriate posture. Further, in the case where the protective cover 28 is provided, since the seed cover enters the soil width from the side of the protective cover 28 at the time of planting, the seedlings can be smoothly planted without receiving the resistance of the soil, and the beak 14 and the fork 15 cannot be planted. Since no strong force acts on it, there is no danger of damage. On the other hand, in the case where the intermittent valve 32 is provided in the width of the liquid transport path of the spray nozzle 17, the amount of liquid to be pumped is small enough to replace the paste fertilizer used in the paddy field with the liquid spray nozzle for seedling planting. Even if it is a thing, a liquid such as water or fertilizer water can be surely jetted toward the planting claw 9 with a high pressure.

[Effect of device]

In short, the present invention is a seedling planting device configured to scrape crop seedlings such as scratches placed on a seedling mounting table for each unit planting stock by a planting claw planting operation and to plant in a field scene. A hole for forming a seedling planting hole below the jetting nozzle on the front surface of the jetting nozzle in the advancing direction while facing the operation locus of the planting nail, and spraying a liquid on the planting nail. Since the forming plate is provided, the planting claws that plant and operate crop seedlings such as scratches placed on the seedling mounting table are scraped for each unit planting plant and planted in the field scene. Since liquid such as water and fertilizer water is sprayed from the spray nozzle facing the planting nail to the planting nail, the seedlings retained on the planting nail can be easily separated, and the seedlings can be planted conventionally. It is possible to prevent the plant from being carried around while it is attached to the attached nail, and to surely plant it in a field scene. Moreover, a hole forming plate provided on the front surface in the traveling direction of the spray nozzle forms a seedling planting hole below the spray nozzle,
Moreover, since the sprayed liquid flows into this seedling planting hole to soften the soil, the root part of the plant seedling to be planted is not directly damaged by the impact from hard soil, and the plant seedlings such as scratches are not damaged. The plant can be planted smoothly and reliably even in a field where the water content is low.
