Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a fork shutter for surely transporting a certain amount of grass seedlings to be placed on a seedling mounting table of a grass transplanter to a seedling picking section.

[0002]

[Prior art]

 A fork shutter was provided above the seedling mounting table of the conventional rush transplanter to ensure that the grass seedlings to be mounted on the seedling mounting table were sent to the seedling picking section. The fork shutter was configured so as to hold down the width of one plant, and the seedling stand moved laterally to the right or left to convey the plant downward by one plant in synchronization with the feeding of seedlings. The grazing seedlings above the seedling mounting table were received by a fork shutter so that they would not fall downward so that the seedlings would not be disturbed.

[0003]

[Problems to be solved by the device]

 However, unlike the paddy rice seedling mat, the grass seedlings to be placed on the seedling mounting table are loosened at the root of a block of rush, then packed in a seedling cassette and transferred onto the seedling mounting table, so that conventional fork shutters are lined up. Because of the configuration, when the rush seedlings on the seedling mounting table are sent downward, if they hit a block of seams, a single fork shutter feed will result in a missing part, resulting in stock stalls, or tears. It became a damaged seedling and adversely affected growth. In addition, if there were areas where the rush seedlings floated, they could be planted with their posture collapsed, resulting in poor growth.

[0004]

[Means for Solving the Problems]

 The problem to be solved by the present invention is as described above, and in order to solve the problem, the tip of the tip is drawn in a parallelogram shape in a side view on the lower part of the seedling mounting table 16 of the grass transplanter. A fork shutter 34 for sending the grass seedlings downward is arranged, the fork shutters 34 are arranged in two rows at right angles to the feeding direction, and the interval b between the rows is set to be not less than the seedling pressing dimension a of the lower fork shutter 34b. .

[0005]

[Action]

 With the above-described configuration, the two rows of fork shutters 34 can widely press a large grass seedling and hold it even if there is a floating seedling, and send the grass grass seedling below the seedling mounting table 16 while holding it. The rush seedlings on the seedling mounting table after being cut off by the planting claws are received by the fork shutters so as not to fall, and since this reception is in two rows, the posture of the rush seedlings that fall due to its own weight is not disturbed.

The planting section B is detachably mounted on the rear end of the machine body through a work machine mounting device C. The planting section B has a seedling mount 16 arranged above the planting mission case 13. A chain case 14 is provided so as to project rearward from the planted mission case 13, and a planting arm 15 is arranged at the rear end of the chain case 14. The planting mission case 13 drives the seedling mounting table 16 from side to side. Further, the planting claws 15 are rotated in an elliptical shape through the chain case 14 to cut a certain amount of rush seedlings on the seedling mounting table 16 and plant them in a field scene.

The seedling table 16 is provided with a rail guide 5 at its lower end and is supported by a seedling rail 6, and is also supported by a rail guide on the back surface of the upper part so that it can slide back and forth. As shown in FIGS. 4 and 5, the stand 16 is detachable from the side along the seedling stand rail 6. That is, the mount 7 on which the seedling mount 16 is mounted is composed of the left and right mounts 7L and 7R and the connecting rods 8 and 8 which connect the left and right mounts 7L and 7R. The caster wheels 7a, 7a are provided at the lower end of each, and the upper end has a receiving portion 7b of the rail guide 5 and a pin hole for fixing with a pin 17 to a fixing portion 16a on the side of the seedling mounting table 16. At the position where the planting section B is opened, the seedling placing table 16 is moved laterally and placed on the receiving section 7b of the pedestal 7L, and the fixing section 16a on the side of the seedling placing table 16 is opened. The pin 17 is inserted into the upper part of the pedestal 7L and fixed, and the seedling mounting table 16 is slid sideways and moved to fix the pedestal 7R to the right side of the seedling mounting table 16 in the same manner. The 7L and 7R are fixed by bolts or the like with the connecting rods 8.8 to form a stand for the seedling stand 16, and The maintenance of the planting unit B with each other to allow easy.

Next, in order to surely plant a certain amount of seedlings of the rush seedlings D to be placed on the seedling placing table 16 with the planting claws 15, the grass is synchronized with the left and right reciprocating movements of the seedling placing table 16. A fork shutter 34 for sending the seedlings D downward is disposed on the lower part of the seedling mounting table 16, and a seedling feeding belt 22 is provided along the mounting surface below the middle part of the seedling mounting table 16. As shown in FIGS. 6 and 7, the fork shutter 34 is provided with a wire-shaped rod bent in a V-shape when viewed from the side so that the tip is perpendicular to the seedling stand 16. The fork shutters 34a and 34b are arranged in two rows in the width direction, and the distance b between the fork shutters 34a and 34b is equal to or larger than the pressing dimension a of the lower fork shutter 34b (b ≧ a). It is possible to press D widely and send it.

An upper portion of the fork shutter 34 is fixed by a mounting body 49, and the mounting body 49 is fixedly mounted on the rotating shaft 21 so as to be rotatable, and both sides of the rotating shaft 21 are slidable. An arm 36 is pivotally supported by a moving plate 35, and arms 36 are fixed to both ends of the rotating shaft 21. The cylinder 10 is interposed between the tip of the arm 36 and the sliding plate 35, and the cylinder 10 is installed. The fork shutter 34 is configured to rotate in the vertical (seedling feeding) direction by expansion and contraction. The sliding plate 35 is fitted in the guide holes 25a and 25b of the support plate 25 fixed to the side plate 24 of the seedling mounting table 16 so that the sliding plate 35 can move in parallel. A cylinder 9 is interposed between the cylinder 9 and the fork shutter 34 so as to slide in the front-back direction (perpendicular to the seedling mounting table 16) by the expansion and contraction of the cylinder 9. Then, the seedling feeding belt 22 is driven on the sliding plate 35 via a rod 40, an arm 45, and a shaft 43 containing a one-way clutch.

Further, as shown in FIGS. 1 and 2, compressed air is sent from the compressor 2 to the electromagnetic valve 4 via the filter 3 and the coupling 19, and the cylinder 9 is supplied from the electromagnetic valve 4 via a hose.・ By switching the electromagnetic valve 4 to the reciprocating movement of the seedling mounting table 16 by sending it to 10, the cylinders 9 and 10 expand and contract in conjunction with the reciprocating movement of the seedling mounting table 16, as shown in FIG. In addition, the fork shutter 34 draws a rotation trajectory c of a substantially parallelogram in a side view, sends a certain amount of the rush seedling D downward, pulls it out in a direction perpendicular to the seedling mounting table, raises it upwards, and again raises the seedling mounting table. It is inserted into the rush seedling D on 16 and sent downward.
