Description

[0001]
BACKGROUND OF THE INVENTION
In the seedling planting machine for supplying mat-shaped seedlings wound in a roll form to a seedling tank and separating and planting them with seedling planting claws, the roll mat-shaped seedlings for supply to the seedling tank are accommodated and supported. The present invention relates to a roll-mat-like seedling support device.
[0002]
[Problems to be solved by the invention]
In the seedling planting using the mat-like seedlings wound in rolls, it is difficult to stabilize the accommodation support of the roll-up mat-like seedlings for supply to be supplied to the seedling tank. Roll-rolled mat-shaped seedlings are easy to move due to the inclination of the vehicle body traveling, and the seedling planting is often unstable due to the movement of the center of gravity.
[0003]
[Means for Solving the Problems]
The present invention, formed on the reel unwinding mat was rolled in (18) Jonae the (A) from seedling tank (1) in the feeding belt (23) in seedlings guide frame (22), 該苗guide frame (22) In a seedling planting machine for separating and planting with a seedling planting nail (2 ) from a seedling inlet (21), a roll winding for accommodating and holding a spare roll mat-like seedling (B) to be supplied to the seedling tank (1) A seedling transplanter (3) having a bent bottom along the form is arranged on the vehicle body (4) , and a reel holder (17) projecting inward is provided under the seedling receiver (3). .
[0004]
【The invention's effect】
A roll mat-like seedling B is accommodated and supported in each seedling receiving base 3 on the vehicle body 4 and the roll-mat mat-like seedling A is supplied to the seedling tank 1 and fed out during seedling planting while traveling. Separated by 2 and planted on the soil surface. When the mat-like seedling A on the seedling tank 1 decreases during the seedling planting operation, the roll-wrapped mat-like seedling B is taken out from the seedling receiving stand 3 and supplied as the mat-like seedling A onto the seedling tank 1.
[0005]
During such seedling planting work, even if the vehicle body 4 is inclined, the roll-wrapped mat-like seedling B is accommodated and supported in the seedling receiving base 3 formed on the bent bottom surface. It is difficult to move, maintains a stable accommodation support posture, maintains accurate seedling planting, and is simple in configuration.
Further, the roll-wrapped mat-like seedling B is formed with a roll surface on the peripheral surface, but the bottom surface of the seedling receiving base 3 is formed on a bent surface along the roll surface, so that The curved surface can be maintained and the feeding as the mat-like seedling A when the seedling tank 1 is replenished can be smoothly performed.
Furthermore, since the reel holder 17 projecting inward is provided under the seedling receiving base 3, the pipe-shaped reel 18 constituting the core material of the roll mat-like seedlings A and B is inserted into the reel holder 17 and held. it can.

DETAILED DESCRIPTION OF THE INVENTION
The seedling planting device 5 has a seedling tank 1 and a seedling planting nail 2, is supported by a center float 6 and a side float 7 that slide on the soil surface, and is rolled from the seedling tank 1. A is planted on the soil surface leveled by the floats 6 and 7 while being separated by the seedling nail 2.
[0007]
Such a seedling planting device 5 is attached to a rear portion of a tractor vehicle body 4 having a front wheel 8 and a rear wheel 9 by a lift link 11 composed of a parallel link mechanism that is moved up and down by expansion and contraction of a lift cylinder 10. The vehicle body 4 has a handle 13 and a cockpit 14 on the steering post 12. The engine 15 below the cockpit 14 travels by transmitting the wheels 8 and 9, and transmits the seedling planting device 5. Let the seedlings grow. The seedling receiving platform 3 is disposed on both the left and right sides of the control floor step 16 between the steering post 12 and the cockpit 14.
[0008]
The seedling receiving stand 3 is configured in two upper and lower stages, and is formed to have a long bottom surface along the roll mat-like seedling B along the front-rear direction, and has a circular claw-like cross section. Although it is formed in a sheet metal shape, it may be made of wire rod material, and is formed in a concave section in front view so that the mat-like seedlings B can be taken in and out from above.
A reel holder 17 that protrudes inward is disposed on the lower stage portion of the seedling receiving base 3, and a used reel 18 is inserted and held. The reel 18 constitutes the core material of the roll-wrapped mat-like seedlings B and A, and is constituted by a simple PVC pipe material. However, the front and rear side disks 19 may be connected by a connecting rod 20. .
[0009]
Before seedling planting work, each seed receiving base 3 is accommodated and supported by the roll-mat mat-like seedling B, and when the mat-shaped seedling A in the seedling tank 1 is fed out and reduced by seedling transplanting work, While taking out the roll-mat mat-like seedling B, it is supplied to 1 part of the rear seedling tank. At this time, the empty reel 18 left in the seedling tank 1 part is inserted and held in the lower reel holder 17.
[0010]
The multi-row seedling tank 1 of the seedling planting device 5 is inclined rearward and downward to reciprocate in the horizontal direction with respect to the seedling guide frame 22 forming the rear lower end seedling inlet 21 and has a mat-like shape on the bottom surface. The feeding belt 23 that receives and feeds the lower surface of the seedling A is intermittently rotated. A reel 18 which is a core material of the rolled mat-like seedling A is supported on the upper portion of the seedling tank 1 by a support arm 24, and the rolled mat-like seedling is driven by the lateral movement of the seedling tank 1 and the driving of the feeding belt 23. A can be fed out to the seedling guide frame 22 side.
[0011]
The seedling planting claws 2 are arranged at the rear part of the seedling planting frame 25 and have a seedling planting trajectory line C that faces the rear lower end part of each seedling tank 1 and uses the seedling inlet 21 of the seedling guide frame 22 as an operating range. The mat-like seedling A fed out to the seedling guide frame 22 is separated and is planted on the soil surface leveled by the floats 6 and 7 below.
Each seedling planting claw 2 includes a rotary case 26 that is rotated with respect to the seedling planting frame 25, a planting case 27 that is rotatably provided at both ends of the rotary case 26, and a double crank mechanism that includes these internal gear mechanisms. Is attached to the planting case 27 and is operated along an elliptical seedling planting locus line C.
[0012]
Such a seedling planting device 5 detects the depth relative to the soil surface by the vertical movement of the center float 6, and controls the lift cylinder 10 to expand and contract to move up and down to maintain the seedling planting depth constant. To perform pitching control. In addition, the horizontal tilt of the seedling planting device 5 is detected based on the vertical movement difference of the side float 7, and the rolling control is performed so that the rolling cylinder is expanded and contracted to maintain the seedling planting device 5 in a state parallel to the soil surface. It is said.
[0013]
The mat-like seedling A supplied to the seedling planting device 5 as described above is grown in a form having a long mat-like seedbed portion with the width of the seedling tank 1 and wound around the reel 18 in a roll form. Thus, when it is supplied to the seedling receiving stand 3 and the seedling tank 1, it is used as a roll-mat mat-shaped seedling A or B having a reel 18. The mat-like seedlings A and B can be planted in a long stroke as a roll winding form.
[0014]
In FIG. 6, the difference from the above example is that a thin and comb-shaped seedling holder 28 that supports the front end edge of the mat-like seedling A on the front lower end edge of the seedling tank 1 is placed inside the seedling guide frame 22. It arrange | positions at the fixed space | interval D so that it may follow. Although this space | interval D is formed narrower than the seedling collection opening 21, you may comprise widely.
In the lateral movement of the seedling tank 1, the leading edge of the mat-shaped seedling A is not in direct sliding contact with the seedling guide frame 22 at a fixed position, and the posture of the mat-shaped seedling A is hardly disturbed.
