Abstract

PURPOSE:To extend the adaptable range for divided seeding blocks in the title device for transplanting seedlings divided from a mat-shaped original formed. CONSTITUTION:The objective device made up of a claw 5 passing, from above downward along the lower end of a stock 2 loaded with a mat shaped seedling 3 in a tilted manner. This claw 5 consists of a pair of left and right plates 8, 8 parallel with each other with the outside bent downward and the inside of the tip of each of said plates 8, 8 is provided with an arc-shaped edge 10 swollen when viewed from above, resulting in enlarging the area of the tip of each of said plates 8, 8.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention is used for a seedling transplanter that divides mat-shaped seedlings, takes them out, and transplants them, and aims to expand the applicable range of the size of the seedlings that can be divided and taken out.

0002

[Prior Art] A seedling dividing device that divides and takes out the mat-like seedlings 3 placed on the lower end of the slanted seedling stand 2 is usually equipped with a sharp tip called a scissor. A claw made of a pair of round rods is used (Utility Model No. 54-127722).
Figure 4 b). These claws cannot be used to separate large seedlings and take them out, so in such cases, claws made of plates called block claws are used (see above (a)).

0003

[Problem to be solved by the invention] By the way, farmers
Depending on the variety of rice, the time of transplanting the seedlings, etc., it is divided into small and large plants. The proper use of these is done by adjusting the width of movement of the seedling stand to the left and right in response to the rotation of the claws, but if you replace the claws and block claws each time you switch between small and large plants, it will save you a lot of work. is difficult.

[0004] The claws have little adaptability to large plants. On the other hand, as shown in FIG. 3, the block claws 5 have straight blade edges 11, 11, so that when the width of the seedlings becomes narrow (small plants), the seedlings are moved from the seedling stand 2 to the mud surface. In practice, the width of seedlings that can be taken out has been limited to about two-thirds of the width of the nail.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a system for passing from the upper side to the lower side the lower end of the seedling stand 2 on which the seedlings 3 in the form of a mat are placed diagonally. The claw 5 is composed of a pair of parallel left and right plates 8, 8 whose outer sides are bent downward, and the inside of the tip of each plate 8, 8 has an arc-shaped blade that bulges when viewed from above. Rim 10,
The present invention provides a seedling dividing device in a seedling planting machine, characterized in that a seedling splitting device is provided with a seedling seedling transplanter.

[0006]

[Example] Next, an example of the present invention will be described. Figure 1
As shown in the figure, the seedling support plate 2 is placed on the left and right sides (
The mat-like seedlings 3 placed on the seedling tray 2 are arranged so that the lower end portions 3a of the seedlings 3 move left and right over the take-out opening 1a of the seedling receiving plate 1. It's done.

A block claw 5 is fixed to the tip of the ¬-shaped seedling planting rod 4, and when the seedling planting rod 4 rotates, the tip of the block claw 5
It passes downward from the upper side of the outlet 1a, reaches the mud, then rises through the left side of the seedling receiving plate 1, and repeats this rotation. The seedling planting rod 4 is provided with an extruder 6 so as to move up and down on the abdomen of the block claw 5, and when the tip of the block claw 5 is above the mud, as shown in FIG. When it reaches the lowest end, it is pushed down by a cam inside the seedling planting rod 4 and moves down to the lower end of the block claw 5.

As shown in FIG. 2, the block claw 5 is divided into left and right parts by a groove 7 from the center down, and is composed of a pair of plates 8, 8. Further, both left and right ends of the respective plates 8, 8 are bent downward to form side plates 9, 9. Note that when the block claw 5 is turned, it assumes a substantially vertical posture at its lower end, but "down" in the above-mentioned "...bent downward..." is the orientation in the posture shown in FIG.

[0009] On the inside of the lower ends of the plates 8, 8, as shown in FIG.
As seen from above, the swollen arc-shaped blade edge 10,1
0 is provided, and the tip is sharp. When the apparatus configured in this manner is operated with a mat-shaped seedling 3 placed on the seedling platform 2, the lower end 3a of the seedling 3 is exposed to the outlet 1a of the seedling receiving plate 1.
, it moves left and right as the seedling table 2 moves laterally. On the other hand, the lower end of the block claw 5 passes through the outlet 1a from the upper side to the lower side, drawing a trajectory perpendicular to the upper surface of the mat-like seedling 3 as the seedling planting rod 4 turns. At this time,
As shown in FIG. 1, the pusher 6 is located above the tip of the block claw 5, so that the blade edges 10, 10 of the block claw 5 and the lower end of the side plate 9 on one side are the lower end of the mat-like seedling 3. Part 3a
Divide it by cutting it. Then, this divided block of seedlings is carried downward while being held by the inner surfaces of the plates 8, 8, the inner surfaces of the side plates 9, 9, and the lower edge of the pusher 6,
In the mud, the block claws 5 are pushed down by the pusher 6.
separated from the soil and transplanted to muddy soil.

Effects of the Invention As described above, the seedling blocks formed by dividing the mat-like seedlings 3 by the claws 5 are separated by the plates 8 of the claws 5,
The seedlings are carried from the opening 1a to the mud by being held by the inner surface of the tip of the plate 8, the inner surface of the side plates 9, 9, and the lower end of the pusher 6. Since the arc-shaped blade edges 10, 10 are provided, the area of the plates 8, 8 that come into contact with the seedling block is increased compared to the conventional blade edges 11, 11 that are straight. Even small seedling blocks with a narrow width can now be hung well. According to the results of experiments, in the case of conventional blades with straight edges 11, 11, the width of the seedling block was at most two-thirds of the width of the claw 5; It was possible to transplant small plants up to 1/2 of the width of the block. It is also possible to increase the area of the tips of the plates 8, 8 by using straight blade edges 11, 11 and making the angle between the blade edges 11, 11 steeper with respect to the forward direction. If this was done, the blocks of seedlings that were taken out would become so soiled that they could not be put to practical use.
