Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a receiving blade support device in a rush transplanter.

(Prior Art) A seedling opening is provided on a front plate integrated with a guide rail of a seedling mounting table, and a receiving blade is provided at the seedling opening.

In order to change the amount of seedlings, the seedling mounting table is moved vertically to adjust the distance from the planting claw. In this case, the guide rails are also moved vertically, (The front-back movement), so that the receiving blade provided on this also moves vertically.

(Problems to be solved by the present invention) When the receiving blades provided at the front and rear portions of the seedling opening as described above are attached to the guide rail on the seedling mounting table side, when the seedling collecting amount is changed, the middle receiving blade is connected. The gap with the planting nail changes. Therefore, it is difficult to adjust the gap to an optimum value suitable for the amount of seedlings collected.

When the seedling collecting amount is adjusted to be large, the seedling mounting table moves to the near side (operator side), so that the gap between the middle receiving blade and the planting claws becomes small.

When the gap becomes small, the planting claw arm and the planting claw bend,
As a result, the intermediate receiving blade and the planting claw may interfere with each other.

At that time, even if the torque limiter operates, the stock will be lost.

The present invention has been devised in order to solve the above-mentioned drawbacks, and a receiving blade support device in a grass transplanting machine in which an optimum gap is secured between a planting claw and a middle receiving blade regardless of the amount of seedlings collected. The purpose is to obtain.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a receiving blade support device in a grass transplanter as described below.

That is, according to the present invention, among the receiving blades arranged at the seedling opening of the seedling mounting table, the middle receiving blade at the lower back side is provided on the chain case side which does not move, and both sides at the upper front of the seedling opening are arranged. Is provided on the side of the seedling table that can move vertically.

Here, the back is the direction in which the aircraft advances, and the near side is the direction opposite to the reverse direction.

(Function) Since the middle receiving blade below the seedling opening is attached to the chain case that does not move except for the seedling platform that may move vertically, the middle receiving blade and the planting claw are attached. , The seedling table can be vertically moved, and the amount of seedlings can be adjusted.

(Example) An example shown in the drawings will be described below.

 First, the operation principle of the turf transplanter will be described.

That is, in FIG. 7, (1) is a fork shutter, (2) is a seedling mounting table, and this fork shutter (1) is a stroke end of the lateral movement of the seedling mounting table together with the seedling mounting table (2), that is, It moves integrally to the seedling collecting final step, and when the stroke end of the lateral movement of the seedling table is reached, the following operation is performed, and at the end of this operation, the seedling table is reversed again as before. Lateral movement in the direction is performed, and the next seedling collecting operation is sequentially performed with the planting claws.

FIG. 7 (a) shows a state where the seedling mounting table (2) has reached the stroke end of the lateral movement together with the fork shutter (1), and the fork shutter (1) faces the seedling opening. And shows where the seedling collection is over.

Next, as shown in FIG. 7 (b), fork shutter (1)
Is lifted from the seedling mounting table (2), and the fork shutter (1) is pulled out of the seedling. In this case, seedling holding plate (3)
The fork shutter (1) is pulled up in a direction not to lift the seedling.

 The above is the lifting operation of the so-called lift operation.

Next, as shown in FIG. 7 (c), a so-called snapping operation and a returning operation are performed in which the fork shutter (1) pulls the seedling toward the seedling opening at an upper position where the fork shutter (1) does not contact the seedling and in the opposite direction. It is.

Next, as shown in FIG. 7 (d), a so-called lift lowering operation for inserting the fork shutter (1) into the seedling is performed.

Next, as shown in FIG. 7 (e), a so-called snap operation of drawing the seedling toward the seedling opening is performed. FIG. 7 (f) shows the movement locus of the fork shutter.

Therefore, the seedlings are sent toward the seedling row and the seedlings are reliably held and the seedling picking operation by the planting claws is performed between the claws of the fork shutter.

Since the operation of the fork shutter as described above surely feeds and holds the seedlings in the seedling collection, the lack of stocks and the variation in the number of plants planted are greatly reduced.

Comb fork claw (5) of fork shutter (1)
Performs the operation described above, so that as shown in FIG.
Fork shutter using two cylinders (6) and (7) and performing a combined motion in two directions with the first cylinder (7) by the link mechanism and the two cam grooves (9) and (10) of the cam plate (8). The lift operation of (1) is performed, and the snap operation is further performed by the second cylinder (6).

Further, the vertical feed belt (11) of the seedling mounting table (2) is adapted to rotate the drive roller (12) to feed vertically by utilizing the above link operation. Specifically, as shown in FIGS. 2 and 3, the fork claw (5) of the fork shutter (1) is used.
Is mounted on the shaft (38), and the fork shutter (1) snaps on the triangular plate (33).
The piston rod (35) of the second cylinder (6) is pivotally supported (36) on a link (37) fixed to the shaft (38).

The shaft (38) slides in the slit groove (10) of the cam plate (8).

The first cylinder (7) pivotally supported (30) on the machine frame for performing the lift operation of the fork shutter (1) has its piston rod (31) pivotally supported (32) on a triangular plate (33). The axis (42) of the triangular plate (33) slides in the slit groove (9) of the cam plate (8).

The link (41) of the seedling feed shaft (12a) is pivotally supported (43) on a rod (40), and the tip of the rod (40) is a triangular plate (33).
It is pivoted to (39).

FIG. 2 shows the lifting operation of the fork shutter (1) and the vertical feeding operation of the seedlings.
Is activated and its piston rod (31) becomes a triangular plate (33)
, The shaft (42) of the triangular plate (33) slides in the slit groove (9), and the shaft (38) slides in the slit groove (10).
The fork shutter (1) is lifted by sliding inside.

By pushing the triangular plate (33), the rod (40)
Pulls the link (41), moves the vertical feed shaft (12a) clockwise in the drawing, and the vertical feed belt (11) of the seedlings is fed vertically.

FIG. 3 shows the operation of lowering the fork shutter lift and returning vertically in the vertical feed. The first cylinder (7) operates to pull the piston rod (31) in the direction of the arrow. The shaft (42) slides in the slit groove (9) and the shaft (38) slides in the slit groove (10), and the triangular plate (33) inclines in the direction in which the two slit grooves are combined. )
Is lowered, the fork shutter (1) is lowered, and the triangular plate (33) is pivoted (39).
The pushed rod (40) is pushed to the left, and the link (41) turns counterclockwise, but the one-way clutch causes the longitudinal feed to return to idle.

In FIG. 1, (13) is a chain case, and (1)
4) is a planting claw arm, and (15) is a planting claw.

In FIGS. 1 and 4, reference numeral (16) denotes a guide rail for the seedling mounting table (2) to move laterally. Seedlings provided on the front plate (16a) of the guide rail (16) shown in FIG. Mouth (17)
There is a seedling receiving blade (18c) at the front (rear side), and front receiving blades (18a) and (18b) at the rear (front side).

(23) is a slide belt, and a guide rail (16)
It is stretched between the seedling openings (17) and (17).

The slide belt (23) is stretched between rollers (19) and (20), and has two tension rollers (21) and (22) close to each other.

The belt (23) is stretched from the outer periphery of the tension roller (21) to the inner periphery of the tension roller (22).
And the rail (2) fixed to the slider belt (23)
4) is located in the slit portion (26) of the seedling mounting rib (25), so that when the seedling mounting (2) moves, the slider belt (23) rotates to avoid friction with the seedling. It has become.

With such a configuration, the belt can be driven with a simple structure, and the belt can be easily replaced, and the belt can be easily replaced.

In any case, the auto-slider is configured by the above configuration. However, since the auto-slider and the chain case (13) are close to each other, a sufficient tension is applied to the slider belt (23). Space is not available and adjustment is difficult, but if the tension rollers (21) and (22) are mounted on one arm and this arm can be rotated, the chain case (13) is avoided without taking up space. Can be adjusted easily.

When the front receiving blades (18a) and (18b) are provided beside the rollers (19) or (20) of the slide belt (23) constituting the auto slider as shown in FIG. When the receiving surfaces (b) are the same, the roots of the seedlings are caught in the space (c), and the seedlings are not evenly supplied to the seedling opening (17). Therefore, the posture of the seedling is disturbed, cut off from the middle of the stem, and becomes rootless.

Therefore, when a dimensional difference (l) is provided between the belt surface (a) and the receiving surface (b) as shown in FIG. The seedlings are supplied to the seedling opening (17) to increase the planting accuracy and the posture of the seedlings is not disturbed. In addition, the number of plants to be planted is stabilized by improving the cutting ability of roots.

Incidentally, (27) shown in FIGS. 4 and 5 shows a seedling guide fixed to the seedling mounting table (2) connected to the seedling opening (17).

The front receiving blades (18a) and (18b) are provided at the rear (front side) of the seedling opening (17) provided on the guide rail (16) of the seedling mounting table (2) as described above. The middle receiving blade (18
When c) is attached and the seedling platform (2) moves vertically to change the amount of seedlings, the middle receiving blade (18c) normally moves vertically because it is fixed to the guide rail (16) of the seedling platform. .

When the intermediate receiving blade (18c) moves, the relation between the intermediate receiving blade (18c) and the planting claw (15) changes, and it is difficult to adjust to the optimum clearance.

Moreover, when the seedling mounting table is advanced so as to increase the amount of seedlings collected, the gap between the center receiving blade (18c) and the planting claw is reduced, and the planting arm and the bent claw are moved by the middle receiving blade. (18c).

The present invention is an improvement of the above point. As shown in FIG. 1, a middle receiving blade (18c) is attached to a chain case (13) which does not move vertically like a seedling mounting table via an L-shaped stay (28). Things. However, the front receiving blades (18a) and (18b) are fixed to the seedling mounting table (2).

That is, the intermediate receiving blade (18c) is welded to the flange portion of the L-shaped stay (28), and the slit groove (29) of the stay (28) is formed.
Fix the stay (28) to the chain case (13) with the bolts (30) and (30) inserted through.

Stay (2) within the size of this slit hole (29)
By moving 8), the position of the middle receiving blade (18c) can be adjusted.

With such a configuration, the relative relationship between the middle receiving blade (18c) and the planting claw (15) does not change even when the seedling mounting table (2) is moved vertically, and therefore, how the seedling load is changed. Regardless, an optimum gap is secured between the planting claw (15) and the middle receiving blade (18c).

(Effect of the invention) According to the invention, regardless of the vertical movement of the seedling mounting table,
Since the middle receiving blade is fixed to a chain case that does not move vertically, such as a seedling mounting table, the relative relationship between the middle receiving blade and the planting claw does not change. Therefore, there is an effect that the planting arm and the bent claw do not interfere with the middle receiving blade, so that there is no lack of stock, and planting accuracy and work efficiency are good.
