Description

DETAILED DESCRIPTION OF THE INVENTION C. OBJECTS OF THE INVENTION (Industrial Application Field) The present invention relates to a transplanting device that uses wrapped seedlings having a certain shape of wrapped soil in the transplant cultivation of agricultural crops.

(Conventional technology) The transplanting device that was originally developed was based on the premise of using seedlings without wrapping soil, that is, by collecting seedlings, and the system used a method in which accidental seedlings were manually fed into the device, and are still used in various places today. There is. This transplanting device must transport individual seedlings from the feeding site to the planting trench and hold them until the roots of the seedlings are covered with soil. I need.

The automatic transplanting equipment that was developed after that was mainly based on the use of seedlings with encasing, that is, the use of encased seedlings, but it inherited the concept of the transplanting equipment that was premised on the use of seedling collection, and was able to align and arrange seedlings. The system is equipped with an Ia structure that transports individual seedlings separated from the seedlings to the planting trench and covers the seedlings with soil, which complicates the mechanism and limits capacity and performance.

In recent years, as part of the solution to this problem, a method has been developed in which individual seedlings separated from the aligned seedlings are allowed to fall naturally from that part and guided to the planting groove using a drop tube and guide, which significantly simplifies the mechanism of the transplanting device. At the same time, it enables the adoption of a mechanism for separating individual seedlings from aligned seedlings at high speed, making it possible to use an extremely simple 15N
The company is now able to provide high-performance implantation devices.

For example, paper tube seedlings, which are one type of seedlings wrapped in soil, are usually grown using a seedling container made of a number of paper tubes arranged in an orderly manner and connected so that they can be separated. The tube-aligned seedlings are separated into individual paper tube seedlings and transplanted, but since the colored soil is much heavier than the stem section, they fall easily and are easy to control their posture. Even when the paper tube seedlings are guided into the planting groove, the colored soil is securely held in the paper tube, so there is no worry that the colored soil will crumble and the operation will become uncertain.

Furthermore, paper tube seedlings are easy to separate from aligned seedlings and are suitable for high-speed separation. For this reason, a drop-type transplanting device using paper tube seedlings has been put into practical use as a compact, high-performance transplanting device with an extremely simple mechanism.

(Problems to be Solved by the Invention) As mentioned above, the adoption of the seedling wrapping method and the dropping method provides an advanced transplanting device and greatly contributes to the universalization of transplant cultivation. With this type of transplanting device, the seedlings guided into the planting trench may fall over and become buried at the bottom of the planting trench before being covered with soil. It was not possible to obtain sufficient reliability.

In other words, when transplanting using the drop method, a planting groove is formed in the field using a trench spreader, and the seedlings are dropped into the planting trench immediately after the trench spreader and immediately covered with soil using a soil covering mechanism. The width of the planting groove is much larger than the thickness of the colored soil of the wrapped seedlings, so the seedlings that have been straightened by touching the bottom of the planting groove will suffer from the shock of falling and the flow of the covered soil. , they tend to fall down in the front-back direction, that is, in the direction in which the planting groove extends, and are sometimes buried at the bottom of the planting groove.

To solve this problem, the negative side of the planting trench is made a slope, the falling seedlings are guided to this slope by a guide, and the sides of the colored soil are placed firmly against the slope of the planting trench. A method was also developed, but in this method, one end of the bottom of the wrapped seedling, which falls naturally in the vertical direction, collides with the slope of the guide, and then instead of immediately sliding down the slope, it falls and falls. In some cases, normal planting was not possible.

The present invention aims to solve the above-mentioned problems, provide a simple and high-performance transplanting device, and dramatically expand transplant cultivation.

(Structure of the Invention) (Means for Solving the Problems) The transplanting device of the present invention uses a wrapped seedling having colored soil of a certain shape, and the width of at least a part of the cross section is the width of the colored soil. A groove opener forms a planting groove that is slightly narrower than that of the seedling, and a constant force is applied in the direction of pushing the seedlings into the planting groove into the planting groove formed by the groover. The system is equipped with a seedling planting mechanism that supplies seedlings in a condition where the seedlings are added.

(Function) In the replanting device 5 of the present invention, a planting groove is formed with a groove opener in which the width of at least a portion of the cross section is slightly narrower than the width of the colored soil, and seedlings are placed in the planting groove. The seedlings are supplied by a seedling planting mechanism that applies a constant force in the direction of pushing the soil into the planting groove, and the ltlm between part or all of both walls of the planting groove and the upper part of the wrapping prevents the seedlings from falling over. Then, cover with soil and plant.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIGS. 6 and 7 show paper tube-aligned seedlings 1 used in the transplanting device of the present invention. This paper tube-aligned seedlings 1 consist of a large number of hexagonal cast-shaped paper tubes that are neatly arranged in a honeycomb pattern in the left-right and front-back directions. Seedling raising containers arranged in a shape and separably connected with water-soluble glue are used, each paper tube of the seedling raising container is filled with colored soil to form the soil encasing portions 2, and seeds are sown in each of these encasing portions 2. The seedlings are grown, separated into individual paper tube seedlings 3 as seedlings in soil, and transplanted.

Next, a description will be given of the transplanted Gi installation.

In FIG. 1, reference numeral 11 denotes a machine frame, and a tractor connecting part 12 is provided at the front upper part of the machine frame 11, and a suppressing wheel 13 is supported by a shaft 14 on the rear part of the machine frame 11. Further, a coulter 15 is mounted on a shaft at the front lower part of the machine frame 11.

A seedling conveyor 21 is provided at the upper part of the machine frame 11 and is inclined forward and downward. In this seedling conveyor 21, roller pulleys 23 are mounted on the front and rear of a conveyor frame 22, and an endless conveyor belt 24 is passed between the front and rear roller pulleys 23.

A receiving plate 25 is connected to the front part of the seedling conveyor 21.

Further, a rotating lN 132 is horizontally suspended on a frame plate 31 fixed to the front part of the conveyor frame 22, and a large number of regulating plates 33 are fixed to this rotating shaft 32. 34 are provided respectively.

The shaft 14 of the suppression wheel 13 and the rotation shaft 32 of the regulation plate 33, and the seedling conveyor 21 and the rotation shaft 32 are connected to the interlocking mechanism 3.
5.36. When the suppression wheel 13 rotates, each regulating plate 33 rotates together with the rotating shaft 32 via the interlocking mechanism 35, and the conveyor belt 24 of the seedling conveyor 21 rotates via the interlocking mechanism 36.

A seedling planting mechanism 41 is provided below the front of the seedling competition p21. This seedling planting mechanism 41 is )-;'+L! A drop pipe 42 is vertically attached to the machine frame 11. This drop pipe 42 has an inlet 43 at the top end widened and gradually narrows as it goes downward, and a discharge port 43 at the bottom end.
4 is formed. Further, a seedling guide body 46 is connected to the lower end of the drop tube 42 . As shown in FIGS. 2 and 3, this guide body 46 has a cross section with an open surface formed by a pair of side plates 47 and 48 and a front plate 49, and has a cross-section in the shape of a cursor. The side plates 47 and 48 are connected to the side surfaces of the tube 42, and cutout portions 50a and 50b are formed in the lower portions of these side plates 47 and 48, respectively.

Furthermore, a lecturer 5 is provided on the front side of the front plate 49 of the guide body 46.
1 is fixed. The rear surface of the 1-tooth holder 51 has a wedge shape whose width becomes narrower toward the bottom, and the width at the lower part is narrower than the width of the encasing part 2 of the paper tube seedling 3. Moreover, this r711'i14 vessel 51 has a sharp shape toward the coulter 15 located forward from its rear surface.

Next, the operation will be explained.

When a tractor is connected to the tractor connecting portion 12 at the front of the machine frame 11 via a three-point link mechanism and pulled, the coulter 15
A thin groove is formed in the (iI field), and a planting groove 61 is further formed through the groove opener 51.

The cross-sectional shape of this planting groove 61 is as shown in FIG.
The shape is the same as that of the rear surface of the groover 51.

At the same time, the suppressing wheel 13 moves forward while rotating, and the rotation of the suppressing wheel 13 is transmitted to the rotating shaft 32.
As the II plate 33 is rotated, the conveyor belt of the seedling conveyor 21 and the paper tube-aligned seedlings 1 placed on the seedling conveyor 21 are sent forward at a constant speed, especially the paper tube seedlings 3 in the front row. A regulating plate 33 is pressed against the soil wrapping part 2 to regulate the position of these paper tube seedlings 3. Then, when the paper tube seedling 3 approaches the rotating shaft 32 to a predetermined position, the separating body 34 provided on the regulating plate 33 separates the paper tube seedling 3 from the paper tube aligned seedlings 1, and the seedling planting mechanism 41 Fall of? It will cost less than ¥42. In this way, the paper tube seedlings 3 are successively separated from one end of the front row of the paper tube-aligned seedlings 1.

In addition, in the case of a II structure in which a plurality of planting grooves 61 are formed at the same time, the arrangement of the regulating plate 33 and the separator 34 is changed, and the drop pipes 42 provided corresponding to the planting 1' 161 are The separated paper tube seedlings 3 may be dropped from the hands.

The paper tube seedlings 3 put into the drop tube 42 from the population 43 are discharged from the discharge port 44 of the drop tube 42 while their position is controlled by the drop tube 42 whose width becomes narrower as it goes downward. be done. Further, as shown in FIGS. 2 to 4, the paper tube seedlings 3 discharged from the discharge port 44 are planted while being regulated by the side plates 47 and 48 of the guide body 46.
61. In this way, the paper tube seedlings 3 are accelerated to a sufficient speed while falling down the drop tube 42 and guide body 46 of the seedling planting mechanism 41.

The cross-sectional shape of the planting groove 61 is a wedge shape that becomes narrower as it goes downward, and the base is the encasing portion 2 of the paper tube seedling 3.
As shown in FIG.
It collides with the lower portions of both side surfaces 61a and 61b of the planting groove 61. Moreover, since the paper tube seedling 3 is accelerated at 1·min while falling as described above, upon collision, it receives a sufficiently large force in the downward direction, that is, in the direction of being pushed into the planting groove 61. Therefore, due to this force, as shown in Figure 5,
The wrapping part 2 of the paper tube seedling 3 digs into the lower part of the planting groove 61, which is narrower than the thickness of the wrapping part 2, so the paper tube i! i'
In the planting groove 61 of i3, a stable posture is maintained with the soil wrapping part 2 facing downward.

In this way, the paper tube seedlings 3 are placed and lined up one after another in the planting groove 61, and the suppression wheel 13 runs beside the planting groove 61 to break up the soil that has piled up horizontally. The paper tube seedlings 3 placed in rows 61 are covered with soil and compacted.

At this time, as described above, since the lower part of the encasing part 2 of the paper tube seedling 3 is biting into the narrow lower part of the planting groove 61, each surface 61a, 61b, 61c of the planting rs61 and the encasing part are in contact with each other. Due to the friction with 2, the paper tube seedlings 3
will not fall forward or backward. Therefore, paper tube seedling 3
will not be buried at the bottom of the planting groove 61.

In the above embodiment, the paper tube of the paper tube seedling 3 is shaped like a hexagonal tube, but the paper tube may be shaped like a square.

In addition, you can use wrapped seedlings with colored soil that has been hardened using a mixer or soil hardening agent, or wrapped seedlings that have been grown in a seedling pot of a certain shape and have firmly retained colored soil in their vigorously developed roots. It's okay.

In addition, in the above embodiment, the impact force between the naturally falling paper tube seedlings 3 and the planting groove 61 was used as the force for pushing the enclosing part 2 into the narrower part of the planting groove 61 than the enclosing part 2. However, it is also possible to mechanically accelerate the wrapped seedlings and use the impact force with the planting groove.

Alternatively, 114% method in which colored soil is directly pushed into the planting groove may be used.

In addition to the suppression wheel 13, a separate prime mover may be used as the drive source.

(Effects of the Invention) According to the present invention, in a planting groove in which at least a portion of the width of the cross section is narrower than the width of the colored soil, a force is applied to the upper part of the capsule in the direction of pushing it into the planting groove. Since the seedlings are supplied with soil, a strong frictional force is exerted between the planting groove and the soil wrapping part, and it is possible to reliably prevent the seedlings from falling back and forth when feeding the soil into the planting groove. Even when covering with soil, the covered seedlings will not fall over due to the flow of covering soil, ensuring reliable planting.

For this reason, in particular, in the past, the falling method was particularly unreliable because the wrapped seedlings guided into the planting trench could fall back and forth due to the impact of falling or the flow of soil, and become buried at the bottom of the planting trench. It is possible to significantly improve the reliability of the implant device, and provide an extremely simple, compact, and high-performance implant device.

Transplant cultivation has also been introduced to agricultural crops that were conventionally sown directly, resulting in a dramatic improvement in agricultural management, and the results of transplantation can be seen in 4 minutes even for famous crops that were conventionally transplanted. .
