Description

[Detailed Description of the Invention] This invention relates to a trap device for planting seedlings grown in a field by filling the valve holes of a seedling box with many valve holes vertically and horizontally and sowing seeds. be.

Conventional beak-type tree planting devices use a soil-covering device to cover the seedlings with soil after transplanting them, but because the device is defective, the soil-covering is not sufficient. Therefore, the Taku-1 type planting device was not suitable for transplanting seedlings with soil.

In the general beak-type planting device FE7, the seedlings with soil are attached to the transfer device of the planting device along with the seedling box, and the seedlings with soil are transferred one by one into the transplanting cylinder of the beak-type cypress attachment device using the drop-off device (drop-off rod). I'm trying to knock it down and transplant it. In this case, the conventional
If you look at the planting trajectory opening of the beak + from the side, the planar shape of the planting hole is long in the front and back direction, because the machine draws a relative trajectory due to the descending movement of the beak → and plants the hole. In particular, the soil covering the rear side in the direction of travel is insufficient.

In this invention, the soil in the planting area is mounded backwards, and the mound is actively moved forward to completely cover the soil. The front and left and right sides are formed into fixed beaks, and the rear side in the forward direction of the aircraft is a movable beak that moves the soil in the planting area backward to form a planting hole when the beak-type planting tube descends. The purpose of the present invention is to configure a seedling planting device with soil in which a soil-covering body is provided at the rear of a beak-type planting tube and moves forward in response to the backward movement of a movable beak. Hereinafter, one embodiment of the present invention will be described based on the drawings.

First, the configuration will be explained. The running vehicle body (1) is equipped with an engine (2) on the front side, and has front wheels (8) and rear wheels (4) (4).
It is supported by and has a handle (5) attached to the rear.

t2 in the planting part (6) provided at the rear of the traveling vehicle body <1)
The placed seedling box (7) has square holes (8) vertically and horizontally (8)...
It is made of synthetic resin and has a square hole (
8) (8)... is filled with bed soil (9) (9)... to form soiled seedlings 00)θ0.... The seedling box (7) is placed on a horizontal base plate (
11) It is placed on the top and always slides in one direction from one to the other by being pushed or pulled by a spring (B). The left edge 0) and the left edge (+4) of the frame into which the seedling box ()) is fitted are provided with a group of small projections 0) and a group of small projections θ6) that protrude leftward or rightward, respectively. The small protrusion groups) and the small protrusion groups 6 are both lined up in the left-right direction at regular intervals, and the escapement aη is engaged with each of the small protrusion groups) and the small protrusion groups 06). A group of vertical drop rods is provided above the last row of square holes (8) of the seedling boxes (7) whose advancement is blocked by the escapement αη.

A relay tube (b) 28 is provided at the bottom of the square hole (8), and a push plate is provided at the lower end of the drop-off rod (e). and,
The upper end of the drop-off rod θ8) is connected to the crank Ωυ, and when the crank shape slides, the drop-off rod θ8) is configured to move up and down. Furthermore, the crank (21) is attached to the rod)
The rod is connected to the L-shaped arm (a) and the vertical movement device of the rod (via 24 to the beak-type planting device).

The escapement 0'7) is used to stop the movement of the seedling box (7), which is constantly trying to move to the other side, by the action of the spring (b), and intermittently moves it one square hole (8) at a time,
The T-type crank Q1) is fixed on the shaft (c), and the crank Q
o is provided with a ring for two claws, and this claw (a) ring is applied to the small protrusion group (b) and the small protrusion group 06), and when the protrusion group (b) on one claw comes off, the ring on the other claw is removed. Nail 0Q is small heaven fever. 2. It approaches the middle of group α6). The vertical movement device Q consists of an upper link rod 00 and a lower link rod H, and a rotating arm (
The center of b) is fixed, and the other end near the connecting piece 0, which is pivoted to one end of the rotating arm (g), is pivoted to the middle of the upper link rod 01), and the other end of the rotating arm (c) is pivoted to the other end of the rotating arm (c). Fit the movable beak (A) of the beak-type planting device (C) into the elongated hole (A) of the other end of the connecting piece ■. The beak-type planting device) consists of the cylindrical shaft and the beak o1), and the beak ◇0 is the front side (6) and the left and right sides in the direction of movement are fixed beaks (goods), and only the rear side is movable. formed in the beak). The transfer #I beak 09) is bent into a crank shape, and a step 0→ is formed in the middle, and the upper end is pivoted to the fixed beak (goods) at @ (b), and the arm α→ is at the 0 o'clock part of the shaft. protruding,
A bottle (B) protrudes from the arm ←, fit the bottle θQ into the elongated hole ■, tension the spring between the bottle) and the right side of the fixed beak 04), and bring the dead center of the spring 09). The movable beak G99) is configured to suddenly and elastically open and close upon crossing over.

Then, pivot the middle of the left and right arms (5'l) (Tl) to the left and right side parts 0- of the fixed beak so that the soil covering device is positioned behind the beak-type planting device (c). At the same time, the free end of the arm σD (ffl) is connected to the movable beak (b) via the engagement pin (rotation), and the soil covering device β0) is moved forward in response to the backward movement of the movable beak (a). It is configured to move to .

Next, the action and effect will be explained. Engine (2
) and move the traveling vehicle body (1) forward by holding the walking steering handle (5), the rotation from the output shaft protruding from the transmission case (c) will be 0 yu on the connecting rod, 0 υ on the upper link rod, Rod e→, L-shaped arm (c), Rondo ψ椴,
While moving the knock-down rod (18) downward via the crank Qυ, the soiled seedlings α0) are pushed down one by one by the push plate of the drop-down rod (18) and flow into the relay tube (1→).Then, the output Due to the rotation of the shaft (on the shaft), the rotating arm (c) and the connecting piece (9

phase]. After that, as the output shaft rotates, when the plant is planted in a relative trajectory as shown by the arrow in Figure 1, the beak αη sticks into the field, resulting in the state shown in Figure 5, but on the other hand, the output shaft H The connecting piece (b) is pulled up by the rotation of the connecting piece (b), and the connecting piece (b) is rotated by the connecting ring into six arms, and the movable beak (a) is moved backward around the axis) to clear the soil in the planting hole. The earth is embanked to the rear, and the seedlings with soil on the rise (b) are planted in well-made planting holes, and the soil covering device moves forward in conjunction with the backward movement of the movable beak (a). The embankment is planted first and the area around the base of the seedlings is covered with soil.

This invention is equipped with a soil covering device that moves forward in response to the backward movement of the movable beak 0 at the rear of the beak-type planting device (c). Planting in holes and covering with soil can be done quickly, and the planted seedlings can be stabilized by sufficiently covering with soil despite having a simple structure.
