Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to the structure of the lower end of the seedling stand of a rice transplanter.

(b) Prior Art Conventionally, there are some rice transplanters in which the lower end of the seedling stand is maintained at a constant distance from the rising surface of the seedling take-out plate.

(c) Problems to be solved by the invention The front end of the seedling pine on the seedling platform rests on the bottom receiving surface of the seedling take-out board, and when planting seedlings in such a state, the seedling pine does not hold the seedlings. It slides sideways with the platform and comes into contact with the bottom receiving surface of the fixed seedling take-out plate, and due to this frictional resistance, the lower surface of the front end of the seedling mat is resisted by the bottom receiving surface of the seedling take-out plate and does not slide smoothly. , the seedling stand follows in the horizontal sliding direction, and eventually wins, and then when the seedling stand slides sideways in the opposite direction, only the seedling stand slides in the opposite direction by the amount that the seedling pine has fallen, and the seedlings are removed. Since the pine trees do not move, there was a risk of stock shortages.

(d) Means for solving the problem In the present invention, a seedling stand partitioned into a certain width by vertical ribs is configured to be able to slide horizontally, and a seedling take-out plate with an approximately L-shaped cross section is provided toward the lower end of the stand. In addition, in the lower end structure of the seedling stand, cut grooves are formed at predetermined positions on the rising surface and the bottom receiving surface of the seedling take-out plate for cutting the seedling blocks by the planting claws. A constant distance is maintained between the lower end of the seedling loading plate of the stand and the rising surface of the seedling take-out plate, and
At the lower end of the seedling plate of the seedling platform, elastic strips are arranged in an extended manner to support the front end of the seedling pine placed on the seedling platform. The purpose of the present invention is to provide a lower end structure of a seedling mounting stand for a rice transplanter, which is characterized by having a substantially flush surface.

(E) Function/Effect According to this invention, the lower end of the seedling plate in the seedling platform has an extended elastic strip for supporting the front end of the seedling pine placed on the seedling platform. Moreover, since the elastic strip and the seedling board are arranged on the same plane, the front end of the seedling pine is supported on the elastic strip, so that the entire bottom surface of the front end of the seedling pine is supported on the elastic strip. It does not come into contact with the seedling take-out board, and the front end of the seedling pine slides accurately in response to the horizontal sliding of the seedling platform, eliminating causes such as missing plants and allowing accurate seedling planting work. It is.

When the seedling pine is vertically fed downward, the lower surface of the seedling pine can be smoothly fed vertically without getting caught on the elastic strips. can be done efficiently.

(F) Example The example of the present invention will be explained in detail based on the drawings.
A indicates a walking-type rice transplanter, and machine a
A prime mover 1 is mounted on the front part of the machine, and power is transmitted to the left and right wheels 3 provided on both sides of the machine body a via an interlocking mechanism 2. 4 is a swing case connected to the left and right wheels 3, and 5 is a swing case connected to the machine body a. A float is installed in the lower center of the fuselage a, and 6 is a side float installed on both the left and right sides.A seedling planting section B is connected to the rear of the fuselage a. Mission case 7
A seedling loading stand 8 with a low front and a high rear height that is connected to the rear end so as to be slidable laterally, and a seedling take-out plate 9 having a substantially L-shaped cross section and serving as a guide rail provided at the lower end of the seedling loading stand 8; It consists of a planting claw 10 provided at the front of the lower end of the seedling stand 8,
11 is a planting arm, 12 is a driven arm, 13 is a driven arm support, and 14 is a crank arm.

The seedling stand 8 holds seedling pine M in a number that matches the number of rows to be planted.
A vertical rib 15 is provided protruding for each width of the seedling pine to place the seedlings, and the lower end of the vertical rib 15 extends to the position of the rising surface 9-1 of the seedling take-out plate 9. The lower end of the seedling mounting plate 16 located between the vertical ribs 15 is formed to be shorter than the lower end of the vertical rib 15, and when the seedling pine M is placed on the seedling mounting plate 16, the lower end of the seedling pine M is shorter than the lower end of the vertical rib 15. It is in a state that it protrudes from the frontmost edge of the seedling board 16.

Therefore, when the planting claw 10 rotates to perform the planting operation, the rising surface 9-1 of the seedling take-out plate 9,
The seedling block M' is cut from the seedling pine M while passing in front of the front end of the short seedling board 16 through the cutout groove 17 provided on the bottom receiving surface 9-2, and the seedlings are planted in the field. .

A locking rail 18 is protruded from the rear surface of the seedling table 8, and the rail 18 is locked to a support rod 19 connected to the lower end of the seedling take-out plate 9, which has an L-shaped cross section, and is attached to the support frame 19. The seedling stand 8 is guided by the supporting rod 19 and slides laterally.

On the lower edge of the seedling board 16, a large number of elastic strips 20 are arranged at regular intervals on the lower side of the lower edge, and the tips of the elastic strips 20 are arranged vertically. It extends to the same position at the lower end of the rib 15. The elastic strip 20 and the seedling board 16 are substantially flush with each other.

The elastic strip 20 is made of rubber or the like, and may be provided in a narrow shape protruding from the notch groove 17 as shown in FIG. 2, or as shown in FIG. 3. By forming the width of the strips to be slightly narrower than the nail width of the planting nails 10, and making the interval between each strip approximately the nail width of the planting nails, the seedlings cut by the planting nails 10 can be cut. In some cases, when the block M' is dropped from the elastic strip 20, the resistance of the elastic strip 20 is uniformly applied to the lower surface of the seedling block.

In the figure, L indicates the width of the planted nail 10, and l indicates the width of the elastic strip 20.

The embodiment of this invention is constructed as described above, and while the machine body a is held on the water surface of the field via the float while traveling on the tiller with the wheels 3, the seedling block M is planted by the seedling planting part B. The planting claw 10 cuts the seedling pine M on the seedling loading board 16 from the notch groove of the seedling take-out plate 9 and plants it as a seedling block M'. The front end of the seedling pine M is supported by the elastic strip 20 that extends flush with the lower end 16-1 of the seedling mounting plate 16, and therefore, the back side of the front end of the seedling pine is covered with seedlings. Since the elastic strip 20 is interposed between the bottom receiving surface 9-2 of the take-out plate 9 without directly contacting the bottom receiving surface 9-2, the seedlings can be easily removed even when the seedling platform 8 is slid horizontally or when it is fed vertically. The rear surface of the front end of the pine will not come into contact with the bottom receiving surface 9-2 of the seedling take-out plate and cause friction or get caught, and the seedling pine M will also be able to accurately respond to the horizontal sliding of the seedling platform 8. Even when the seedling table 8 moves horizontally in the opposite direction, accurate planting can be performed without causing any missing plants. The seedling block passes through the notch groove 17.
When cutting M' and rotating the elastic strip 20 downward, the seedling block M' is moved downward while bending the elastic strip 20 downward against the elastic force.
As soon as the same seedling block M' finishes passing through the notch groove 17, the elastic strip 20 bent downward returns to its original state due to its elasticity.

Therefore, according to the above embodiment, the seedling pine M placed on the seedling platform 8 is placed at the lower end 16-1 of the seedling platform 16 in the seedling platform 8 at the extended lower position 16-2. Since the elastic strips 20 for supporting the front end of the seedling pine M are arranged in an extended manner, and the elastic strips 20 and the seedling mounting plate 16 are substantially flush with each other, the front end of the seedling pine M Since it is supported on the same elastic strip 20, the entire bottom surface of the front end of the seedling pine does not come into contact with the seedling take-out plate 9, and the front end of the seedling pine M is accurately moved in response to the lateral sliding of the seedling platform 8. The parts also slide to remove the causes of missing plants and allow for accurate seedling planting work.

When the seedling pine M is vertically fed downward, the lower surface of the seedling pine M can be smoothly fed vertically without getting caught on the elastic strips 20, and the structure as a whole is simple. This has the effect of making rice transplanter work more efficient.
