Description

[Detailed Description of the Invention] The present invention is an improvement on a device for transplanting seedlings of vegetables such as cabbage or field crops such as leaf tobacco.

Seedlings of field crops must be planted correctly along the top of the row. Especially in the case of mechanical planting, the length of the raising and lowering process of the planting claw is always constant, so if the seedlings are planted at a position that is off the top of the ridge, the planting depth will be too shallow and the seedlings will fall over or not grow healthy. There is a possibility that

The purpose of this invention is to always plant seedlings correctly along the top of the ridge.

This will be explained based on the embodiment shown in the drawings. Reference numeral 1 denotes an engine, and its power is transmitted to a moving shaft 3 via a transmission 2.

4 is a drive wheel that runs on the bottom of the groove between the ridges;
They are arranged oppositely on the left and right sides of the machine body so as to straddle the ridges of the strips, and their axles 5 are pivotally supported by a chain case 6. 7 indicates a chain stretched between the dynamic shaft 3 and the axle 5.

Reference numeral 8 denotes a pair of left and right shaft cylinders rotatably fitted around the outer periphery of the moving shaft 3. The outer wall of the chain case 6 is fixed to the left and right outer ends of the shaft cylinders 8, respectively. A pair of left and right moving rods 9 are fixed.

Reference numeral 10 denotes a rotating plate having an isosceles triangular shape in plan view, the apex of which is pivoted to the fuselage 11, and both ends of the base connected to the rotating rod 9 via connecting rods 12, respectively.

A large number of projections and recesses are arranged in parallel to the bottom side of the swivel plate 10 in an arc shape, and engaging members 13 which can rise and fall are engaged with these in a freely releasable manner.

When the transplanter is to be moved along a ridge on the contour line of a slope, the operating lever 14 is operated to raise the engaging element 13 to disengage it from the rotating plate 10, and the operating handle 15 is again moved to the mountain side. Press down. As a result, the left and right chain cases 6 turn separately, the drive wheels 4 on the mountain side rise relative to the fuselage, and the drive wheels 4 on the valley side descend.

At this time, the left and right shaft cylinders 8 rotate in opposite directions, respectively, and rotate the rotating plate 10 via the rotating rod 9 and the connecting rod 12.

After changing the height of the left and right drive wheels and making the aircraft horizontal, the engager 13 is lowered and engaged with the swivel plate 10 to fix the height of the left and right drive wheels 4, thereby making the aircraft horizontal. maintain it.

Next, reference numeral 16 denotes a rotating pot that rotates intermittently, and when the pot moves to a fixed position, the bottom plate 16a opens and the seedlings stored in the pot are dropped into the planting claws 17 below.

The planting claws 17 descend while holding the seedlings, and when they reach the top of the ridge, they open their tips and plant the seedlings into the soil.
Reference numeral 18 denotes a leveling plate for leveling the top of the ridge, and 19 a pair of conical compression rolls for pressing both left and right sides near the top of the ridge. These, together with the rotating pot 16 and the planting claw 17, are assembled into a frame 20. to form planting unit A. 20a is a turnbuckle provided at the center of the left and right pressure rolls.

Therefore, in the present invention, the mounting hitch 21 provided on the front side of each planting unit A and the overhang plate 122 fixed to the outer periphery of the shaft tube 8 are connected by left and right parallel links 23. Reference numerals 24 and 25 denote vertical pins serving as rotational supports at the front and rear of the link 23, and the link 23 moves left and right on a plane including the chain case 6 using the front and rear vertical pins 24 and 25 as support points.

Reference numeral 26 denotes a crankshaft for driving the upper and lower parallel links 27 that vertically raise and lower the planting claw 17, and is connected to the output shaft 28 of the mission 2 via a key 29 and two universal joints 30 on the front and rear thereof, and is connected to the output shaft 28 of the mission 2 through a key 29 and two universal joints 30 on the front and rear thereof. A
The rotation of the output shaft 28 is reliably transmitted to the crankshaft 26 even if the output shaft 28 is moved parallel to the left and right by the parallel link 23.

Reference numeral 31 denotes a locking rod connected to the mounting hitch 21 in a freely undulating manner, which engages with one of the many irregularities formed on the rear edge of the overhanging plate 22, and is connected to the left and right parallel links 23.
fixed in an immobile state.

In the present invention, when working on a level ground, the engagement of the locking rod 31 is released to free the left and right parallel links 23. At this time, the pressing rolls 19 rotate in contact with both sides of the ridge, and move the unit A in parallel to the left or right along the meandering ridge, so that the planting claw 17 at the center of the unit A is always positioned at the top of the ridge.

When working on a slope, the drive wheels 4 on the mountain side are raised and lowered to level the machine as shown above, and the drive wheels 4 on the valley side are raised and lowered, but as shown in Figure 5, the top of the ridge on the slope shifts toward the mountain side. Therefore, planting unit A
is moved parallel to the mountain side, and the locking rod 31 fixes the parallel link 23 in an immovable state. This allows the heavy planting unit A to be correctly set at the top of the ridge without moving to the valley side.

In short, in this invention, the frame 20 of the planting unit A is attached to the shaft tube 8 with the left and right parallel links 2.
3 through vertical pins 24 and 25, and the horizontal angle of the parallel link 23 can be freely moved or fixed at any angle, so that the center of unit A is always aligned with the top of the ridge, whether on flat ground or on a slope. This produces the effect that the seedlings can be correctly transplanted to the top of the ridge using the planting claws 17.
