Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a transplanted seedling method in which seedlings transplanted by a transplanter into a planting bed formed into ridges in a field are covered with a mulch film (sheet) spread over the top surface of the planting bed. This invention relates to improvements in coating methods.

The seedlings transplanted to the planting bed in the field by the transplanter are covered with vinyl sheets at the same time as the transplanting operation using a vinyl sheet laying device installed at the rear of the transplanter, so that the transplant hole into which the seedlings were transplanted is free from moisture. There are known means to avoid problems caused by being left in a state where it is susceptible to steaming for long periods of time. As the vinyl sheet is being applied, it may shift from the top surface of the ridge to the left or right or float up, making it impossible to obtain the desired covering effect, and there is also the problem that the covered sheet may fly away in the wind.

The present invention aims to solve this problem and to promote early establishment and early growth of transplanted seedlings.

In order to achieve this objective, the method of covering transplanted seedlings according to the present invention is to connect a multi-film laying device to the rear of the transplanter, and to install ridges on the left and right sides of the front end of the transplanter. Furrow guide plates are provided that come into contact with the left and right ridge surfaces of the planting bed, and the transplanter is moved along the planting bed using the left and right ridge guide plates, and the transplanter leaves a certain interval on the planting bed. Then, form a transplanting hole and transplant the seedling to the bottom of the transplanting hole.
The present invention is characterized in that the upper surface of the transplant hole after transplanting the seedling is covered simultaneously with the transplanting operation by the film laid by the film laying device attached to the rear of the transplanter.

To explain the embodiment in detail based on the drawings, 1 is a normal two-wheel type vehicle that runs by driving left and right drive wheels 11 mounted on the machine frame 13 by a prime mover 12 mounted on the machine frame 13. With a hand tractor (tiller), its machine a
On the left and right sides of the front end, there are left and right ridge guide plates 14 that act on the ridge surface so that the machine a moves along the ridges formed in the field.
14 and supporting wheels 15, 15 for holding the ridge guide plates 14, 14 at a predetermined height are attached and supported.

Reference numeral 2 denotes a transplanter which is connected to the rear part of the body a of the hand tractor 1 and is operated by traveling as the tractor 1 travels.

This transplanter 2 has a ring-shaped seedling input hopper 22 installed above its main frame 20 that rotates endlessly above the transplanter 21 as the machine a advances. On the left and right sides of the seedling input hopper 22, seedling stands 23, 23, on which young seedlings grown in seedling boxes are placed and set, are installed.

Further, the transplant device 21 is to be transplanted to the bottom of the transplant hole P while drilling a transplant hole P in the ridge surface, and is supported by a transplant arm 25 configured as a link mechanism that is controlled to be vertically movable by an actuating device 24. Seedling input hopper 22
Receive seedlings dropped from ... and transfer the seedlings to the transplant hole P.
It is configured to be transplanted to the bottom of the .

Reference numeral 31 denotes a main rod of the multi-film laying device 3 connected to the main frame 20 of the transplanter 2 by a connecting rod 32. On both left and right sides of the main rod 31, there are formed ridges on both sides of the ridges. Grooving plates 33, 33 are provided to form grooves,
Behind the groove cutting plates 33, 33, both hem portions 34b, 34 of the multi-film 34a fed out from the winding roll 34 are placed.
treading wheels 35, 35 that press and hold b, and both hem portions 34 of the multi-film 34a held down by the treading wheels 35.
Covering wheels 36 and 36 that cover soil b and 34b are arranged in that order, and these treading wheels 35 and 35 and covering wheels 36 and 36 are arranged in that order.
are mounted and supported on rotatable arms 37 extending rearward from both left and right sides of the main rod 31.

The arms 37, 37 are mounted in an inverted eight-shape when viewed from above, that is, the distance between them gradually narrows toward the rear, and the mounting holes 37a... bored in the arms 3T, 3γ... On the other hand, by moving the mounting position of the treading wheels 35, 35 back and forth and installing them, the left and right treading wheels 35, 35,
If the opposing distance between the tread wheels 35 and 35 is adjusted, and the opposing distance between the treading wheels 35 and 35 is narrowed, the pressure applied to the ridge surface will become stronger, and the tension in the left and right direction of the multi-film 34a will become stronger, and if the opposing distance is increased, It is possible to adjust so that the pressure applied to the ridge surface becomes weaker and the tension of the multi-film 34a in the left and right direction becomes weaker.

In addition, the winding roll 34IIi, the multi-film 34
A is wound into a bundle, and both ends of it are attached to the main rod 3 above.
It is rotatably supported by left and right film arms 38 extended from 1.

39 is a hollow pipe that forms an arcuate fold that follows the cross-sectional shape of the ridge surface so that the multi-film 34a fed out from the winding roll 34 can be easily laid along the ridge surface. This is the guide rod that has been created, and has the function of folding the multi-film 34a to be fed out into an arc shape according to the surface shape of the ridges, and also in the clockwise direction (solid line position) and counterclockwise direction (dash line position) as shown in Fig. 1. By rotating the multi-film 34a in the forward and backward directions (left and right directions), the tension of the multi-film 34a can be adjusted.
A support arm 40 extending forward (to the left in FIG. 1) from the center of the guide rod 39 is rotatably supported by a set screw 41 on the main rod 31, and fixed and supported by changing the setting position of the guide rod 39. I am trying to get it.

In addition, a flexible rod 42 that can be deformed and fixed into a desired shape, such as a flexible tube, is inserted through one end of the guide rod 39, and each free end protruding from both free ends of the guide rod 39 is connected to the main rod. The flexible rod 42 is slidably connected to left and right holding arms 43, 43 extending from the guide rod 31, and the flexible rod 42 is bent into a desired shape according to the change in the set position of the guide rod 39, thereby holding the multi-film 34a. It is strained so that it acts accurately on the left and right side edges.

Next, the effects will be explained.

In the method of the present invention, as described above, a multi-film laying device is connected and attached to the rear of a seedling transplanter, and the transplanter makes transplant holes at regular intervals in a planting bed formed into ridges. While transplanting seedlings to the bottom of the transplanting hole, the top surface of the transplanting hole after transplanting the seedlings is covered with a film laid by the film laying device attached to the rear of the transplanter. When covering at the same time as the work, ridge guide plates are provided on the left and right sides of the front end of the transplanter that contact the left and right ridge surfaces of the planting bed formed into ridges, and these ridge guide plates allow the transplanter to By moving the plastic sheet along the ridges, the vinyl sheet laying device attached to the rear of the transplanter can be moved correctly along the planting bed. The film that is formed in the planting bed and immediately covers the seedlings to be planted at the bottom of the transplant hole and the bottom of the hole is placed so that the film accurately covers the top surface of the ridge. Since the seedlings are laid down, problems such as drying out of the seedlings and the cultivated soil around them, collapse of the peripheral wall of the transplant hole, and problems of insufficient laying of the vinyl sheets can be solved.
