Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simultaneous scratching and transplanting machine capable of simultaneously scratching and planting a seedling.

[0002]

2. Description of the Related Art Conventionally, a sowing machine for simultaneous transplanting, in which a plowed field is flooded and a seedling is planted simultaneously with a sowing process, is shown in FIG.
As shown in FIG. 6, a float group 7 consisting of an outer float 70 and a middle float 71 is supported by a planting device 6 mounted on a multi-row planting type rice transplanter as shown in FIG. It is configured to drive the device 5.

The planting device 6 is commonly used as a conventional rice planting planting device 6 without the scraping device 5, and the middle float 71 has a wide front end similar to the outer float 70. It is formed in a shape having a sled portion, and the middle float 71 and the outer float 70 are implanted on the surface on which they slide. Further, the front-rear distance K between the front end sled portion of the float and the scraping device 5 is arranged as close as possible in order to reduce the body length.

[0004] The driving system in the above-described device will be briefly described. The horizontal rotating shaft 63a supported in the transmission case 63 is separated from the body by a predetermined distance to the right of the rolling support shaft 31. The bevel gear 8 provided in the input portion case 63b by the drive shaft 8 driven from the first side.
The seedling table 61 is driven through the a and 8b, and reciprocates left and right of the seedling mounting table 61 and performs seedling planting operation of the planting claws 62a.

[0005]

However, in the conventional simultaneous scraping transplanter constructed as described above, as shown in FIG. 6, the float in which the front sled portion of the middle float 71 is wide and located on both sides is used. The front end portions 70 are arranged side by side in a wide T-shape, and further close to the front scratching device 5. Therefore, the muddy water flowing backward through the rotor mounting interval 5k between the scraping devices 5 and the muddy water scraped rearward by the rotor are generated.
It stays in a state where it merges into the front and rear distance k between the and the float group 7, that is, a so-called blocking state. In this state, the retained muddy water and the like are vigorously discharged outward from both sides of the outer float 70.

[0006] The muddy water flow has a considerable momentum due to the pumping action generated by the rotation of the rotor of the scraping device 5, causing a disadvantage that the already planted shoots are pushed down, and furthermore, the mud flow is blocked by the float group 7. The generated muddy water causes large running resistance. Due to such a problem of blocking muddy water, the traveling speed of the transplanter cannot be increased, and therefore, when performing the simultaneous planting work, the water impregnated in the field is dropped once. After performing the above-mentioned work in the state where muddy water flow is small, there is a problem that complicated water management is required such that water must be supplied again and flooded.

[0007] The planting claws holding the seedlings slide the field scene where the float group 7 is softly raked by the rotor, so that the seedlings are planted in the field scene which is pushed down one step lower. 7, the plant is planted on the step formed in the field scene, and there is also a problem that the plant is inclined by mud.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. A in FIG. 1 is a transplanter according to the present invention, which is provided with an engine E, a steering wheel 2, a steering wheel, a seat, and the like from the front on an upper part of a body 1 having a front wheel 1a and a rear wheel 1b. A hitch 30 is provided at the rear end of the elevating mechanism 3 composed of a top link, a lower link, etc., which is raised and lowered by a hydraulic cylinder mechanism for automatic control of the planting depth, and a rolling support shaft protruding rearward from the hitch 30. In contrast to 31 (FIG. 6), a central portion in the width direction of the planting device 6 provided with the substitute device 5 is supported by a shaft so as to be freely tiltable (rollable) right and left via a metal portion.

The planting device 6 includes a rolling support shaft 31.
Conventionally, a transmission case 63 in which a seedling mounting table 61 and a planting portion 62 having planting claws for five-row planting are arranged is mounted on a planting machine frame 60 formed with a metal portion that fits into a metal part. It is similar to that of Under the transmission case 63, a float group 7 having a leveling plate function and a sliding function can be moved up and down through the front and rear support links 7a and 7b (FIG. 2) by the following arrangement shown in FIG. It is provided so that

That is, the float group 7 composed of the above-mentioned sliding body
Are provided on both sides of the planting portion, and the two sides on which seedlings N for one row are planted on both sides are straight (rectangular plate-shaped).
An outer float 70 for the strip and a pair of right and left sides, both sides of which have the same straight shape as described above so that a single row of seedlings can be planted at the center of the outer float 70. And a float 71.

The front part of the outer float 70 is shown in FIG.
As shown in (A) and (B), a broken piece 7b having a triangular shape in a plan view may be formed from both sides of the sliding surface 7a between the strips to form a shape like a squid. The breaking piece 7b has a predetermined height (usually 20 mm or more) higher than the sliding surface 7a of the outer float in side view.
(Approximately 50 mm) along the high position, it is possible to break down and even out only the portion of the soil mass that protrudes more than the flooded surface in the field scene, whereby the soil mass protrudes to the water surface and Weeds are prevented from growing.

In addition, the outer float 70 and the middle float 71 have their rear ends located at a position forward or approximately to the point where the seedlings are planted by the planting claws 62a, thereby shortening the overall length as much as possible. Thus, the weight of the float group 7 is reduced, and the momentum of the muddy water flowing down the passages 73 and 75 formed between two adjacent floats, which will be described later, can be reduced.

The shape of the outer float 70 is not limited to that shown in FIG.
Can be used. In short, it is preferable to form the position of the mounting interval between the two rotors so that the float slides as described later.

The sled-shaped tip of the middle float 71 has a semicircular shape with little resistance to muddy water flow, and a passage 73 formed between the two middle floats 71 is formed in front of the planting position as described later. This is a portion that is scraped by the central rotor 5d, and the float 71 is configured to slide and level the unscratched portions on both sides of the rotor 5d. Further, two passages 75 are formed between the outside of the middle float 71 and the inside of the adjacent outer float 70, respectively. Therefore, three passages 75, 73, 75 are provided behind the scraping device 5.
Is formed.

The front ends of the outer float 70 and the middle float 71 are aligned in the horizontal direction, and a rearward and rearward distance K is provided behind the scraping device 5 so as to relax and relieve the force of the muddy water flow during the scraping. Thus, the muddy water and mud which the scraping device 5 scrapes through the passages 75, 73, 75 and the outside of the outer float 70, and the muddy water and mud (hereinafter referred to as muddy water) which the float group 7 pushes forward on the front surface thereof are good. It is configured to be able to pass through.

In this embodiment, the two middle floats 71 at the center of the float group 7 have an automatic hydraulic pressure sensing control mechanism (planting depth control mechanism) having the same configuration as the conventional one.
The lifting and lowering mechanism 3 is operated up and down by vertical movement when the float 71 slides on the ground so that the planting depth is kept constant. Further, as shown in FIGS. 2 and 3, the scraping device 5 is configured such that both sides of a rotor shaft 50 provided laterally to the planting width in front of the sliding body 7 are pivotally supported by a transmission case 63. One end is supported on a shaft 65 and is rotatably supported by support arms 66 and 66 extended rearward, and the planting machine frame 60 shown in FIG.
An up / down adjustment mechanism 67 with a handle provided on the side is connected to the support arm 66, and the operation of the up / down adjustment mechanism 67 moves the scratching device 5 up and down to adjust the scratching depth. ing.

Further, as shown in FIG. 3, the planting device 6 is provided with the center of the two middle floats 71 and the planting claw 62a associated therewith behind the extension of the center axis P of the rolling support shaft 31 as shown in FIG. Are disposed between the middle floats 71 and on both sides thereof. The left and right frame plates 5 each having a shaft stopper hole 52 as shown in FIG.
The outer periphery of 3 is connected at predetermined intervals by a scratching plate 55 to form a cage. Then, as shown in FIG. 3 and the like, cage-shaped rotors 5a to 5d are formed in different lengths, and
2 are fixed on the shaft with an attachment interval A to D between adjacent rotors 5a to 5d so that the front of the rotor 2 can be properly replaced.

That is, the longest rotors 5a, 5a are arranged on both outer sides of the scraping device 5, the next length rotors 5b, 5c are arranged between the two support arms 66, and the shortest rotor (5 The center rotor 5d is arranged on the right side of the rotor case 51, and the center line P thereof is arranged so as to coincide with the center line P of the middle floats 71, 71 described above. The five rotors 5a to 5d arranged as described above precisely scrape the planting strip in front of the planting claws 62a of the respective planting sections 62 arranged rearward, and are scraped flat. Seedlings can be satisfactorily planted in the open field.

The five rotors which are short for each planting portion 62 as described above are provided in a state where the mounting intervals A to D are sufficiently widened between adjacent rotors. Therefore,
Through the distances A to D, the muddy water flow generated by the rotors 5a to 5d at the time of scraping is properly released backward.

Simultaneous Transplanting Scratch A Configured as Above
In the cultivated and flooded field, the scraping device 5 is rotated by the drive shaft 9 while the planting device 6 is lowered and the float group 7 composed of the sliding body is slid on the surface of the ground. Meanwhile, the water flow is caused to flow down while smoothly guiding the water flow to the rear of the planting device 6, so that the flow to the side is reduced as much as possible.

Also, the planting lines formed by a plurality of planting claws 62a correspond to the passages 73 and 75 formed by separating the outer float 70 and an appropriate number of middle floats 71 from each other. Each of the rotors 5a to 5d, each having a short length for each planting claw 62a and formed in a single body, can accurately scratch the ground for each planting streak even if there are local irregularities on the ground surface. Since the planting claws 62a directly plant the seedlings in the flat and soft field scene immediately after the scratching by the scraping device 5, the seedlings grasped by the planting claws 62a are tilted into the ground. The seedlings can be planted smoothly by preventing the occurrence of seedlings, and the planted seedlings stand in a proper posture with a predetermined depth in the field scene. It can be promoted well.

Since the planting device 6 controls the planting depth accurately through the middle float 71 and controls the planting depth up and down through the elevating mechanism 3, the seedlings can be satisfactorily planted at a constant depth. At this time, the scraping device 5 scrapes out muddy water on the ground surface as the scraping direction rotates and proceeds. Since this muddy water flow passes through the attachment intervals A to D formed between the rotors 5a to 5d and is drained rearward, the muddy water flows from both sides of the float disposed behind the scraping device 5 like a conventional device. The muddy water flow is not drained vigorously, and tilting of the planted seedling at this site can be prevented.

The muddy water that has passed through the mounting intervals A to D hits the sled surfaces at the front ends of the outer float 70 and the middle float 71 disposed behind this part, and the momentum is reduced. The muddy water flows raked by the rotors 5a to 5d are smoothly discharged rearward through the central passage 73 and the lateral passage 75 while being merged. Therefore, the muddy water that stays at the front-rear interval k and tries to vigorously drain to both outer sides of the float group 7 like the conventional device is formed by a passage 73 formed at the center of the middle float 71 and the passage 73. The air is efficiently discharged rearward from a passage 75 formed on the side of 73.

Further, most of the muddy water flow can be released through the width of the float group 7 composed of a plurality of floats through the passage 75 formed between the straight middle float 71 and the outer float 70. , Both outer floats 70, 70
Can reduce the amount of muddy water drained from the side and reduce the momentum, and it is possible to satisfactorily prevent the planted seedlings that have already been planted from being pushed down.

The unscratched portions of the rotor mounting intervals A to D are pressed into the ground by the weight of the middle float 71 and the outer floats 70, 70 to form flat float traces. The part does not protrude from the water surface, and is flattened to substantially the same height as the field scene scraped by the scraping device 5, so that weed growth can be prevented, and seedlings can be placed in a place where the field scene is flat. Since the plant is planted, the seedlings do not tilt due to the mud flowing down to a lower place due to the step in the field as in the related art.

Therefore, when the simultaneous planting work is carried out as in the conventional apparatus, it is possible to omit the step of once dropping water impregnated in the field or to reduce the degree of dropping water. Therefore, advantages such as simplification of water use regulation management can be provided.

[0029]

According to the present invention, the following effects can be obtained by the configuration described above. According to the invention of claim 1, when performing the simultaneous planting work for scratching, in the field scene immediately after the scratching by the scratching device 5, directly to the field that has been scraped without being floated and flattened by a float unlike the conventional one. Planting seedlings in
The seedlings can be planted in an appropriate posture, and the growth of the seedlings can be improved.

In the simultaneous planting operation of the scraping device according to the second aspect of the present invention, the muddy water sent backward from the mounting interval of the rotor of the scraping device 5 comes into contact with the front ends of the outer float and the middle float. Since it is possible to divide and pass through each passage while weakening the force, muddy water flow discharged from the front side of the outer float to the outside can be suppressed, and it is possible to prevent the over-planting seedlings from being pushed down. . In addition, when planting seedlings in the passage, they are leveled by the scraping device 5, so that the seedlings can be planted well.
