Description

Description Vegetable transplanter Technical field

TECHNICAL FIELD The present invention relates to a vegetable transplanting machine in which vegetable seedlings such as onion, leaf leek, white leek, etc. of one strain taken out from a seedling tray by a seedling claw are directly planted directly in a field. Background art

For example, as disclosed in Japanese Patent Application Laid-Open No. 2001-1121, conventionally, a seedling taken out from a seedling tray of a seedling mounting stand by one seedling taking-out nail is used for another lower seedling-attached nail. There is a successor-type vegetable transplanter that uses a set of seedling removal nails and a seedling planting nail to inherit and plant one seedling.

However, in the case of the above-mentioned succession method, not only the drive of the seedling extraction nail and the drive of the seedling planting nail are required, but also the synchronization is required, so that the structure becomes extremely complicated, and the seedling extraction nail is obtained. When the seedlings are transferred to the seedlings, the seedlings are disturbed in their posture.In particular, as the planting speed increases, the disturbances become more pronounced and the seedling placement accuracy is reduced. . Disclosure of the invention

An object of the present invention is to provide a vegetable transplanter that has a simple structure and does not require the succession of seedlings as described above, which causes a decrease in planting accuracy, and that can perform reliable and high-speed planting. It is.

In order to achieve the object, a vegetable transplanter according to the present invention has a seedling claw for taking out a seedling from a seedling tray on a seedling mounting table and planting the seedling in a field. Thus, since the seedlings themselves take out the seedlings from the seedling tray on the seedling mounting table, the conventional seedling removal claws are unnecessary, and therefore the seedling inheritance that causes the above-mentioned problem is eliminated. Improve seedling planting accuracy. In order to realize a seedling-planting claw that also serves to take out seedlings from the seedling-carrying platform, in the vegetable transplanting machine of the present invention, the seedling-planting claw is a rotating end portion of a rotating rotatable member. The trajectory of the swinging fulcrum of the seedling-claw during the planting process is centered on the rotation fulcrum of the rotary member. It has a substantially triangular shape, one vertex of which is used for the seedling removal movement of the above-mentioned seedling-growing nails from the seedling tray, and the other vertex is used for the above-mentioned seedling-growing nails of which the planting is performed on the field.

As described above, the substantially triangular trajectory of the swinging fulcrum of the seedling-claw is represented by a transmission mechanism from the rotation fulcrum of the rotary member of the mouth member to the swinging fulcrum of the seedling-claw (for example, a planetary gear). This can be achieved by devising gear mechanisms and cam mechanisms. By using the two vertices, the advancing / retreating operation of the seedling mounting claw for picking and planting seedlings can be easily exhibited.

Further, the first rotary member is the first rotary member, and the base end of the second rotary member is rotatably attached to a rotating end that rotates about the rotation fulcrum. The seedling is attached to the distal end of the second rotary member. Providing a swinging fulcrum of the claw; attaching the seedling-claw to the swinging fulcrum; rotating the one-way opening member in one direction; Combination with rotation in the opposite direction to one rotary member produces a substantially triangular trajectory of the seedling-claw, and the rotation of the first and second rotary members is centered on the swing fulcrum. By combining the swinging of the seedling mounting nails, the seedling removal movement and the seedling mounting movement of the seedling mounting nails are caused to appear.

In this manner, the substantially triangular movement of the swinging fulcrum of the seedling-growing claw that appears by the rotation of the first and second rotary members is combined with the swinging of the seedling-growing claw about the swinging fulcrum. Thus, the seedlings with the seedlings can be advanced and retracted at a substantially right angle with respect to the seedling tray and the field, and the seedlings with the seedlings can be smoothly taken out and planted.

In the vegetable transplanter of the present invention as described above, a seedling pushing member is attached to the seedling mounting claw in order to facilitate planting of the seedling, and a seedling pushing cam for driving the seedling pushing member is provided. In the axial direction of the fulcrum of pivoting the seedling planting nail, The first and second row members are provided on opposite sides.

Thus, the first and second opening members and the seedling-claw can be easily mounted without affecting the mounting dimensions of the left and right lateral directions (the rotational fulcrum axis and the swing fulcrum axis direction). By incorporating a seedling extruding cam, it is possible to extrude seedlings reliably with a compact and easily removable structure, and to improve seedling planting accuracy.

In addition, the vegetable transplanter of the present invention as described above can open and close the seedling-planting claw to facilitate planting of seedlings. It is provided on the side opposite to the first and second rotary members via the seedling mounting claw in the axial direction of the swinging fulcrum of the seedling mounting claw.

Thereby, the first and second rotary members ゃ the claw opening and closing cam can be easily formed without affecting the mounting dimensions of the seedling mounting claw in the left-right width direction (the rotation fulcrum axis and the swing fulcrum axis direction). By incorporating this, it is possible to reliably open and close planted nail seedlings in a compact and easily removable structure, and to improve seedling planting accuracy.

The above and other objects, features, and effects of the present invention will become more apparent from the following description based on the accompanying drawings. BRIEF DESCRIPTION OF THE FIGURES

A plate-like opening / closing cam 22 is fixed to an outer end of a cam shaft 53 projecting outward from the swing shaft 49, and the port 63 is brought into contact with an outer peripheral cam surface 22a of the opening / closing cam 22. Then, the left and right claw bodies 20 and 21 are opened and closed by the rotating cam action of the opening and closing cam 22.

Also, a seedling pushing member 64 for pushing the seedling N to the left and right claw bodies 20 and 21 is provided in the pushing mechanism 23, and the seedling pushing member 64 is attached via a shaft 65 and a pushing arm 66. The plate-shaped seedling extruding cam 24 is fixed to the inside of the opening / closing cam 22 at the outer end of the cam shaft 53, and is supported by the arm shaft 67 of the source plate 57. The cam roller 69, which is mounted via the shaft 68, is brought into contact with the outer peripheral cam surface 24a of the seedling pushing cam 24 with a torsion spring 70 force to rotate the seedling pushing cam 24. The configuration is such that the seedling pushing member 64 moves up and down along the left and right claw bodies 20 and 21 by the rolling cam action.

In addition, the seedling extruding member 64 is either a linear seedling extruding member 71 formed of a linear body or an elastic plate-shaped seedling extruding member 72 formed of rubber or resin material as shown in FIG. In the case of the linear seedling extruding member 71, the base annular portion 71a is supported by the shaft 65 of the pushing arm 66, and the distal annular portion 71b is attached to the left and right claw members 20-21. The seedling N is pushed out by the ring-shaped part 7 1 b by loose fitting, while the elastic plate-shaped seedling extruding member 7 2 slides the leading end side inside the left and right claws 20 ・ 2 1 2 sheets The base end of the elastic plate 73 made of rubber or resin material is fixed to one mounting plate 74 to form a bifurcated shape, and the base end of the mounting plate 74 is the shaft 6 When the elastic plate 73 is moved down along the inner surface of the left and right claw bodies 20 and 21, the seedling N is extruded and the soil It is configured to drop soil.

The gate-shaped guide 75 is fixed to the port 75 head, and the upper, lower, left, and right sides of the seedling pushing member 72 are regulated by the guide 75 so that effective seedling pushing is performed. It is configured to do so.

Also, the base plate 57 equipped with the seedling mounting claw 16 and the seedling pushing member 64 is detachably fixed to the mounting plate 56 of the oscillating shaft 49 via a port 77 so as to mount the seedling. At the time of maintenance and inspection of the claws 16 and the seedling extruding members 64 and the replacement of parts, the base plate 57 can be removed to enable easy work.

Further, the driving of the cam shaft 53 is performed during the driving of the oscillating shaft 49 (the idle gears 52, 55), which is the driving of the planting pawl 16, and the groove cam 19 and the oscillating cam 44 are driven. The output gear 54 of the camshaft 53 is rotated by one rotation with respect to the output gear 50 of the oscillating shaft 49 (for example, the output gear 50 When the output gear 54 has one rotation), the cams 22 2 and 24 always rotate at a constant speed against the swinging of the seedling claw 16, and the force 22 2 2 Opening and closing of left and right claw body 20 4 enables smooth extrusion operation.

In other words, even when the first and second rotary cases 17 and 18 are rotating, when the swing arm 44 is, for example, in a swing stop state, the cam shaft 53 rotates once while the swing shaft 4 rotates. Numeral 9 is used to set the rotation to 0 and to keep the swinging stop of the seedling-mounted claw 16, and when the arm 44 swings back and forth by the cam action of the groove cam 19 as in this embodiment. While the cam shaft 53 keeps one rotation, the swing shaft 49 rotates by a certain angle according to the swing of the swing arm 4 4 to swing the seedling claw 16 (vertical swing). .

Then, a seedling mounting table 14 that freely slides in the left and right direction via a guide roller 26 and the like is arranged at the center of the machine body in the traveling direction, and the seedling tray 15 is held in a substantially vertical position near the extraction position. Seeding opening side of seedling tray 1 5 facing backwards, seedling seedling stand 14 The seedlings N are taken out by rushing into the pot shown in Fig. 5, and as shown in Fig. 3, Fig. 10, and Fig. 14 to Fig. 17, the first mouthful case 17 is centered on the input shaft 31. When one rotation is made in the counterclockwise direction (the direction of the solid arrow), the second mouthful case 18 is rotated twice in the clockwise direction (the direction of the broken arrow) around the output shaft 43, and the case is rotated about the shaft 43. During the rotation of the motor 18, the output shaft 53 is moved along a substantially (positive) triangular basic trajectory K as shown in FIG. With the relative change between the swing groove cam 19 provided on the shaft 28 and the swinging arm 44, the seedling mounting claw 16 is caused to perform a swinging operation, and the seedling mounting claw is set on the planting locus A. A series of planting operations from taking out the seedling N from the seedling tray 15 to planting it on the ridge M of the field is performed with a single seeding claw 16 .

The planting locus A is projected forward and downward at the upper seedling removal position and the lower seedling planting position, and has a gentle downward slope backward from the seedling removal position to the middle of the seedling planting position. In the middle from the seedling planting position to the seedling removal position, it is formed almost vertically, and between the middle position and the seedling removal position, it is formed to be more forward than the horizontal. 5 Seedling N from the lower side of the seedlings Nail 1 6 'approaches, pull out the seedling N backward without damaging the seedling with the nail 16 The extracted seedling N moves smoothly downward from the seedling tray 15 without disturbing the seedling N above the seedling tray 15 by moving to the lower rear of the claws 16 and keeps the seedling posture near the planting of the seedling N. It is configured to plant good seedlings N that are almost vertical.

As a result, when the first rotary case 17 makes one rotation in the clockwise direction and the second rotary case 18 makes two rotations in the counterclockwise direction, each seedling claw 16 forms one loop of the planting locus A. The planting is performed twice by the seeding claw 16 having a 180 ° phase difference, and the position of the seeding claw 16 in FIG. Figure 18 shows the 1st opening and closing case 17 being rotated 45 ° clockwise and the second rotary case 18 being rotated 90 ° counterclockwise. As shown, the seedling claw 16 moves counterclockwise on the trajectory A, changing from the 0 ° and 180 ° positions to the 45 ° and 2225 ° positions. To rotate 7 to 90 ° or 135 ° and the second rotary case 18 to 180 ° or 2700 °, as shown in Fig. 16 and Fig. 17, 0. · When it changes to the position of 270 ° or 135 °-315 °, when the 1st opening and closing requisition 17 turns 1 turn and the 2nd revolving case 18 turns 2 turns, Returning to the state, one seedling planting claw 16 completes the loop of one planting locus A by one rotation of the first mouthful case 17 and one rotation of the second rotary case 18. is there.

During exercise along the locus A of the seedling claw 16, when the seedling claw 16 is immediately in front of the seedling removal position, open the left and right claw bodies 20-21 and plunge into the seedling tray 15. When the right and left claw bodies 20 and 21 are closed, the seedling N is clamped, and when the seedling claw 16 is at the lowest planting position, the left and right claw bodies 20 and 21 are opened to open the seedling N. After that, the seedling pushing member 64 is moved downward, and the seedling N is pushed out from the nail body 20 · 21 and planted in the field. The approximately vertical movement of the seedling claw 16 for seedling planting is performed before and after the passage of the lowest point of the locus of the equilateral triangle of the oscillating shaft 49 (cam shaft 53) in a side view. It appears in the movement of.

Then, the seedling mounting table 14 is located on the front side in the forward direction of the fuselage, and the seedling 6 is arranged, and the right side seedling mounting claw 16 is moved in the counterclockwise rotation path A with respect to the left side seedling mounting table 14 in side view. The seedling N into the seedling tray 15 without harming the seedling N with the nail 16, and smoothly pull out the seedling N from the seedling tray 15 without disturbing the seedling N above. The seedling removal accuracy can be improved. The forward and backward movement of the seedling placement claw 16 for seedling placement in the front-rear direction is caused by the movement of the swinging shaft 49 (the camshaft 53) before and after the frontmost vertex of the trajectory of the equilateral triangle in a side view. It appears in motion.

In addition, the output shaft 39 of the first rotary case 17 that is the first rotary member that rotates about the input shaft 31 that is the central rotary shaft is attached to the second rotary member 18 that is the second rotary member. At the same time, attach the seedling-mounted claw 16 to the swing shaft 49, which is the output shaft at the tip of the second rotary case 18, and place the seedling-mounted claw 16 around the swing shaft 49. To move the tip along the seedling trajectory A, and rotate the first rotary case 17 one rotation through the second rotary case 18 Two seedlings 16 In this way, seedlings can be planted twice, making high-speed planting easier.

Further, a groove cam 19, which is a swing cam for swinging the seedling-claw 16 around the swing shaft 49 (cam shaft 53) of the second mouthpiece case 18, is used as the first rotary case 1. It is provided at the center of 7, so that it is possible to easily swing the seedling claw 16 optimal for taking out and planting seedlings, and to improve planting workability.

As described above, the base end of the second rotary case 18 is connected to the output shafts 39 provided at both ends of the first rotary case 17 rotating about the central input shaft 31, and One case 1 8 The tip swing shaft 49 is moved in a substantially (positive) triangular locus when viewed from the side, and it is pivoted about the swing shaft 49. By mounting 16, the claw 16 with seedlings is moved along the seedling locus A.

Further, as described above, the seedling claw 16 is provided with a seedling extruding member 64 for extruding the seedling N sandwiched between the seedling claw 16 and the pushing operation. An extruding cam 24 for performing this operation is disposed on the cam shaft 53 at a position opposite to the rotary cases 17 and 18 via a seedling mounting claw 16. In this way, the extruding cam 24 can be easily assembled without affecting the mounting dimensions of the first and second row re-cases 17 18 The seedling N can be reliably pushed out with a structure that is easy to attach and detach, and the seedling placement accuracy can be improved.

Also, the claw opening / closing cam 2 2 for opening and closing the left and right seedling mounting claws 16 is opposite to the rotary case 17 18 via the seedling mounting claw 16 on the cam shaft 53. It is located at the side position. In this way, the compact opening and closing cam 22 can be easily assembled without affecting the mounting dimensions of the first and second mouth one-off cases 17-18 and the seedling mounting claws 16 in the left-right width direction. In addition, it is possible to reliably open and close the seedling claw 16 with a structure that is easy to attach and detach, thereby improving seedling planting accuracy. Industrial applicability
