Description

[Detailed explanation of the invention] (Field of industrial application) This invention relates to a transplanter for transplanting seedlings into fields, such as ball screws, cabbage, and cedar seedlings, and aims to improve livability and reliability. It is.

(Prior art) Two flexible discs are guided to open at the top, and when an operator supplies seedlings in this open position,
The seedlings are transplanted to the field at the lower end. This is because the seedling supply position is at one point.
There is no leeway in the work, leading to problems with worker fatigue and work efficiency.

To solve this problem, JP-A-50-105427
The invention of the issue appeared.

(Problems to be Solved by the Invention) The above invention has a long seedling supply range and is efficient, but the endless belt can only rotate on one surface. Therefore, the worker who feeds the seedlings faces sideways with respect to the forward direction, resulting in an unnatural posture and severe fatigue. It is also long from front to back, making it unbalanced.

This idea eliminates these deficiencies.
The transplanter is constructed from a single endless belt, allowing the operator to position himself in a forward-facing position and supplying seedlings with a long feeding width.

(Means for Solving the Problems) In other words, this invention is such that the single endless band 9 is folded into a vertical portion A in the vertical direction and a horizontal portion B in the horizontal direction so that its turning surface is bent when viewed from the rear. multiple guide wheels 20;
21, 22..., and this endless band 9 is driven by turning so that the front side of the vertical part A becomes the downward side and the rear side becomes the upward side, and a plurality of seedling receiving plates 35 are wound around the endless band 9 vertically. mounted to rotate around the sides,
A holding plate 37 that approaches the seedling receiving plate 35 and pinching the seedlings is attached to the forward side side of the seedling receiving plate 35 so as to rotate around it and open elastically, and a pair of guide rods 39, 4
0 horizontally supports the seedling receiving plate 35 from below on the rear side of the horizontal part B of the endless band 9, brings the holding plate 37 close to the seedling receiving plate 35 on the front side of the horizontal part B, and supports the seedling on the descending side of the vertical part A. Receiving plate 35
This transplanter is characterized in that both the holding plate 37 and the holding plate 37 are protruded forward in a state where they are close to each other, and the holding plate 37 is provided so as to open from the seedling receiving plate 35 at the lower end.

(Function) Since this invention is constructed as described above, the operator places onions and other seedlings on the seedling receiving plate 35 on the rear side of the side portion B with the roots facing backward.
Here, this seedling receiving plate 35 is placed on the rear side of this lateral part B,
Since the front side, the descending side in front of the vertical part A, and the ascending side thereof are turned in this order, the seedling also moves in this direction. That is, when the seedlings on the seedling receiving plate 35 come to the outside of the side part B, they are held between the holding plate 37, which is pushed by the guide rod 40 and approaches from above, and this seedling receiving plate 35,
In this state, turn and pass the front side of the horizontal part B with the roots facing forward, and then, in this pinched state, descend the descending side of the vertical part A with the roots facing forward, reach the ground, and press the presser plate. 37 is released from the guide rod 40, opened, and transplanted to the field.

(Effects) As described above, according to this invention, since the worker supplies the seedling receiving plate 35 at the laterally long lateral portion B, the worker can work in a forward posture. Therefore, the planter is in a natural posture, with less fatigue, and there is plenty of room to feed the seedlings.
There is no supply leakage, and the system can be configured in two rows to improve efficiency.

Furthermore, the length of the front and back of the transplanted aircraft is short, and the balance and turning performance of the aircraft are good.

In particular, such an effective transplanter is characterized by being inexpensively constructed with a single endless band.

(Example) Next, an example of this invention will be described.

As shown in Fig. 5, 1 is a running vehicle body, and a transmission case 3 is equipped with a pair of drive wheels 2, 2 on the left and right sides.
An engine 5 covered by a bonnet 4 is mounted on the top of the engine 5, a pilot seat 6 is provided in front of the engine 5, and a pair of frames 8, 8 are extended forward from the front part of the seat base 7 at a constant interval from side to side. The front ends of the frames 8, 8 are connected by a front frame 9. A front support frame 12 is rotatably attached to this front frame 9 using vertical pins 10 and longitudinal pins 11, and front wheels 13, 13 for steering are attached to both ends of the front support frame 12.
A pedal 15 provided at the front side of the step 14 is turned in the front and back direction via a rod 16, thereby forming a steering device.

17 is a groove wheel, which is connected to the left and right frames 8, 8;
It is installed at the front between the wheels and is designed to create a groove of a predetermined width on the soil surface of the field when running.

Reference numeral 18 denotes a transplanter frame which is shaped like a "transplanter" when viewed from the rear, and its lower end side is fixed to the frames 8, 8.

19 is a single endless belt, and guide wheels 20, 21,
22, 23, 24, this endless belt 19
The traveling part is vertical part A in the vertical direction and this vertical part A
The structure is such that a sloped portion C is located at the upper side of the slope and a substantially horizontal lateral portion B is formed at the upper side of the sloped portion.

In addition, as shown in FIG. 2, the guide wheel 20 is attached to the shaft 25 at the lowest end between the frames 8, 8, and the shaft 25 is applied with tread pressure to crush the groove made by the groove making wheel 17 from the left and right. It is configured to be driven from a shaft 27 on one side of the wheels 26, 26 via sprockets 28, 29 and a chain 30.

Reference numeral 31 denotes a seedling holding and transporting body, and as shown in FIG. 34 is integrally provided with a flat seedling receiving plate 35, and a pin 36 is attached to the upper side in the transfer direction.
Attach the presser plate 37 rotatably with
7 is configured to be opened from a seedling receiving plate 35 by a spring 38. A plurality of seedling holding and transferring bodies 31 configured as described above are provided on the endless belt 9 at equal intervals.

Reference numerals 39 and 40 denote guide rods, which are arranged to face the seedling receiving plate 35 and the holding plate 37 of the seedling holding and transferring body 31. The guide rod 39 is provided between the starting end of the horizontal section B and the terminal end of the vertical section A of the endless band 19, and the guide rod 40 is provided between the terminal end of the horizontal section B and the terminal end of the vertical section A. While the seedling holding transfer body 31 is moving in the horizontal part B, it is in the open state by the spring 38, and from the terminal end of the horizontal part B, it is closed and moved, and in the vertical part A, it is lowered forward and moved there. It is designed to open at the end.

In addition, 41 is a preliminary seedling mounting stand.

In the above configuration, the front wheel 13 straddles the ridge,
13 and driving wheels 2, 2 are arranged, each part is driven by an engine 5, and the traveling vehicle body 1 is moved forward. Then,
The grooving wheel 17 creates a line of groove on the upper surface of the ridge. Further, due to the rotation of the tread wheels 26, 26, the pulley 20 is rotated by the sprockets 28, 29 and the chain 30, and the endless band 19 turns. Therefore, the seedling holding and transferring body 31 is rotated, and only the lower side of the lateral portion B of the endless band 19 from its starting end to its terminal end is received by the guide rod 39, and the upper presser plate 3
7 is transferred in an open state. At this time, the operator supplies the seedlings to the opening. However, since the space between the horizontal portions B of the endless band 19 is provided in a form that extends to both left and right sides with respect to the vertical portion A, it can be provided longer on the left and right than the conventional one, and the seedling holding and transporting body 31
Since the process of opening and traveling in a horizontal state is extended, the operator can feed seedlings slowly and accurately.

In this way, when the seedling holding transfer body 31 supplied with seedlings reaches the end of the lateral part B, the upper guide rod 4
0, it is pressed against the spring 38 and closed. Then, it reaches the vertical portion A and opens at its lower end. When the seedling is opened, the root part of the seedling is cut into the groove ring 17.
The left and right tread wheels 2 are inserted into the groove created by
6, 26 crushes the groove and is reliably transplanted.
