DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strainer for unraveling lump of rush.

[0002]

2. Description of the Related Art In rush, a lump of a plant is unraveled before transplanting a seedling to produce a small plant for transplanting. For this reason, a method is used in which a lump of stock is inserted into the orbit of a reciprocatingly driven stock releasing claw and lifted up at the place where it is released.

[0003]

For this reason, continuous work is not performed, and it is necessary to manually rotate the rush to unravel the lump from the surroundings.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to contact a rush plant in a passage 3 with the passage 3.
And the forward stroke and the outlet of the passage 3 in contact with the strain of grass in passage 3 to move toward the outlet from the forward stroke toward the opposite direction
A stock release nail 4a that repeats a return stroke moving on the same trajectory
Is a reciprocating drive in a state where the forward stroke moves longer than the return stroke.

[0005]

In the grass-grass disintegrating machine constructed as described above, when a lump of rush grass is put into the passage 3, the crushed claws 4
a comes into contact, and the stalk releasing claw 4a moves toward the exit of the passage 3 in the outward stroke, so that the rush is sent out to the exit side. The stock release claw 4a moves for a long time, and the mass of the stock is released by this difference. Thereafter, in the return stroke, the movement of the stock release claw 4a changes in the reverse direction, and the lump of the stock is released and returned. Since the moving distance of the stock dismounting claw 4a is longer than the return stroke, the lump of the stock is sent toward the exit of the passage 3 while the lump is released by repetition of the forward stroke and the return stroke.

[0006]

As described above, according to the present invention, the grass that wants to enter the passage 3 is sent to the exit of the passage 3 while the clumps of the stock are unraveled by the repetition of the forward and backward strokes. Grass breaking operation can be performed continuously while obtaining grass breaking action. In addition, the stock release nail 4a is the same in the forward travel and the return travel.
As the trajectory moves, the rush
The clumps of the strain are correctly solved.

[0007]

Next, an embodiment of the present invention will be described. FIG.
As shown in FIG. 2, a pair of semicircular wire rods 2 are vertically arranged on the right side of a vertical machine frame 1 so as to face each other in front and rear to form a passage 3. A disk 4 is arranged beside the disk, and a stock release claw 4 a on the outer periphery protrudes into the passage 3. In addition, the four wire rods 2 are provided side by side, respectively.
A part of the stock release claw 4 a of the disk 4 projects into the passage 3 from between the respective rods 2.

A motor 5 is provided at the lower part of the machine frame 1, and its output shaft 6 projects to the left. An intermediate shaft 7 is disposed thereon, on which a swing plate 8, a normal rotation plate 9 and a reverse rotation plate 10 are mounted. The eccentric wheel 11 is fixed to the output shaft 6, and the upper end of a rod 12 that moves up and down by this rotation is connected to the rocking plate 8 with a pin 13. When the output shaft 6 rotates, the rocking plate 8 It swings around 60 degrees around it.

As shown in FIGS. 4 and 5, on the outer periphery of the normal rotation plate 9, claws having a radial clockwise locking surface 9a and a subsequent inclined surface 9b are provided at intervals of 30 degrees. On the outer periphery of the reversing plate 10, claws having a radial counterclockwise locking surface 10a and a subsequent inclined surface 10b are provided at intervals of 30 degrees.
In FIG. 4, the claws of the reversing plate 10 are drawn by chain lines for differentiation. The pin 14 is fixed to the normal plate 9 and the reverse plate 1
The both ends of the spring 17 are hung on a protruding part from the long hole 15 and a pin 16 protruding from the reversing plate 10.

[0010] The normal rotation claw 18 and the reverse rotation claw 19 are attached to the swinging plate 8 by a shaft 20 and pushed by a spring 21 so that the normal rotation claw 18 is engaged with the locking surface 9a and the reverse rotation claw 19 is moved to the system surface. 10a. When the support leg 19a protrudes upward from the reversing claw 19 and is pushed by the push rod 22, the reversing claw 19 rotates clockwise, and the reversing claw 19 is separated outward from the locking surface 10a.

Accordingly, when the swing plate 8 is pulled down by the rod 12, the swing plate 8 swings around the intermediate shaft 7 approximately 60 degrees clockwise. Then, the forward rotation claw 18 is engaged with the locking surface 9a,
The normal rotation plate 9 rotates approximately 60 degrees clockwise. At this time,
The pin 14 is engaged with the right end of the elongated hole 15, and the reversing plate 10 is also rotated in the same direction by substantially the same angle. The reversing claw 19 slides on the slope 10b. Then, near the end of the rotation, the push rod 22 hits the support leg 19a, and the reversing claw 19 is pushed clockwise to separate from the top of the locking surface 10a. Further, when the rotation reaches the end, the pin 16 is pulled by the spring 17 and the reversing plate 10 rotates clockwise, and the left end of the elongated hole 15 contacts the pin 14, and by this rotation, one The locking surface 10 a also extends into the left side of the reversing claw 19. Subsequently, the rod 12 starts to push up, and the swinging plate 8 rotates approximately 60 degrees in the counterclockwise direction. However, the forward rotation claw 18 slides on the slope 9a, and the reverse rotation claw 19 The claw gets over the claw, engages with the next claw, and rotates the reversing plate 10 approximately 30 degrees counterclockwise. That is, when the motor 5 rotates,
The rod 12 reciprocates up and down, and the normal rotation plate 9 and the reverse rotation plate 10 repeatedly swing approximately 60 degrees clockwise and approximately 30 degrees counterclockwise, respectively.

As shown in FIG. 3, the normal rotation plate 9 is fixed to the intermediate shaft 7 by a key 23. The tooth wheel 24 is fixed to the left end of the intermediate shaft 7, and the tooth wheel 26 is fixed to the tooth wheel 26 fixed to the operating shaft 25.
7 is wound (FIG. 2). The disk 4 on the front side fixed to the operating shaft 25 rotates clockwise at a predetermined angle in FIG. 1 and rotates counterclockwise at half the angle. .

A tooth wheel 28 is fixed to the intermediate shaft 7 and the transmission shaft 2
A gear 30 fixed to 9 meshes with this. A chain 34 is wound around a tooth wheel 31 fixed to the transmission shaft 29 and a tooth wheel 33 fixed to the operating shaft 32, and the rear disk 4
Is fixed to the operating shaft 32, and the disk 4 rotates counterclockwise at a predetermined angle in FIG. 1 and then rotates clockwise at half the angle.

Although the forward / reverse rotation device shown in the figure is constituted by a crank motion, it can be constituted by a forward / reverse rotation motor.

Therefore, when a lump of rush is introduced into the passage 3, the tip of the crushing nail 4a is pierced into the passage 3 and the rocking plate 8 is pulled down by the rod 12, so that the mulling is released. 4a moves toward the exit of the passage 3, and the rush is sent to the exit side.
Due to the resistance at the time of the stock release longer than the moving distance of the stock
a is moved so that the mass of the strain is scraped by this difference. Thereafter, when the swinging plate 8 is pushed up by the rod 12, the stock resolving claw 4a moves in the reverse direction, and the lump of stock is unraveled while being sent back. Since the moving distance of the stock dismounting claw 4a is longer than the return stroke, the lump of the stock is sent toward the exit of the passage 3 while the lump is released by repetition of the forward stroke and the return stroke. In addition, the lump of stock turns while being sent due to the difference in resistance received from the left and right with respect to the passage 3, and the lump of stock is released from the surroundings by the claw 4.
a.

Therefore, the grass that wants to enter the passage 3 is sent toward the exit of the passage 3 while the clumps of the stock are disentangled by the repetition of the forward and backward strokes. Can be performed continuously. When the stock is sent to the exit, the lump turns due to the difference in resistance that the lump receives from the left and right (differences in the degree of difficulty in unraveling the lump of the lump, etc.), and the lump is dislodged from the surroundings. The lumps are effectively disentangled. In addition, when it is set as the structure in which the stock release claw is provided only on one side of the passage, due to the resistance of the lump of rush grass received by the passage 3, the lump turns and receives the action from the surroundings to effectively remove the lump. Will be understood.

FIGS. 6 and 7 show that rush is sandwiched between upper and lower flat belts 35 and 36, and the lump of the plant is broken on the way. Shows what is cut off. That is, flat belts 35 and 36 which feed the middle part of the grass between the upper and lower sides are provided so as to protrude the lower one to the left, and the middle is twisted by the rollers 37, 37 so that the grass is upright on the right. It is made to do.
The wire rods 2 and the disc 4 are provided beside the horizontal portions of the flat belts 35 and 36, and the lump of stalks of the rush grows on the outer circumference of the disc 4 while being sent in the Kodaira posture. 4a. At a position after the flat belts 35 and 36 are twisted and the grass is in an upright posture, a pair of cutters 38 and 38 are provided below the plant, and the roots protruding from the plant are cut. It is supposed to. Also, on the right, cutter-3
9, 39 are provided so that the leaves of the rush may be cut to make the height of the grass uniform. The grass to be trimmed is sent by the flat belts 35 and 36 and stored in the container 40, and the cut leaves are separated by another conveyor 41 into the container 4.
It is sent out of zero.
