Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a seedling-raising device dividing feeder for dividing a seedling-raising device into three parts and reliably feeding the seedling-raising device into a seedling box during transplanting work in transplant cultivation.

[Conventional technology and its problems]

Traditionally, paper tubes for raising seedlings have been used for beet transplant cultivation. This seedling raising paper cylinder is a hexagonal paper cylinder.
It is a collection of 1,400 trees chained together in a honeycomb shape, and is quite large, measuring 30 cm in width, 120 cm in length, and 13 cm in height, and weighs about 60 kg.

A tractor-pulled transplanter is used to transplant the paper cylinders for seedlings to the main field. The transplanter has a loading platform for loading seedlings, and the loading platform is designed so that three seedling boxes each 40 cm wide can be set every 40 cm. Therefore, as mentioned above, the length of the paper tube assembly is 120 cm, so when placing it on the loading platform, the length of the paper tube assembly should be divided into 1/3 pieces to match the width of the seedling box 40 cm and transplanted. Put it on the plane.

The conventional process of dividing paper tube aggregates involves manually inserting a fork under the seedlings, lifting them diagonally upwards, dividing them, and feeding them into seedling boxes. Because this divisional supply work is hard labor, it is the responsibility of adult males, who must take on two tasks during the transplanting process: operating the transplanter and dividing the supply work.

In addition, in order to prevent seedlings from deteriorating, only the amount that can be loaded onto the transplanter is divided and fed, so dividing feeding is required several times a day. As a result, transplanting work in the main field has been interrupted, resulting in a huge loss in terms of work efficiency and economy.

[Means for solving problems and their effects]

In order to solve the problems of the above-mentioned prior art, the seedling growing device dividing feeder of the present invention has the following configuration.

That is, the seedling raising device dividing feeder of the present invention includes a trapezoidal frame 1 and a shaft 3 suspended above the trapezoidal frame 1.
and first and third loading platform units ₅ , 5'' fixed to collars C5 and _C7 , respectively, which are rotatable independently of each other on the shaft 3, and first and third stoppers 7, 7 with projections, 1st and 3rd loading platform unit 5,5'' on shaft 3
the second unit fixing collar D ₅ fitted between the
A second loading platform unit ₅ ' fixed to D5, and second left and right stopper fixing collars _D7 , which are integrated with stands s on both sides of the second loading platform unit 5', and second left and right stoppers with protrusions fixed to _D7 . 7′,7″
and a link mechanism 8 that integrally pushes and opens the first and third loading platform units 5, 5', 5'' and the first and third protruding stoppers 7, 7'' which are in close contact with each other onto the shaft 3; first, second and third unit lifting bars 6, 6' for rotating the first, second and third loading platform units 5, 5', 5'' around the shaft 3;
In the split feeder of the present invention, the seedling growing device 12 is first placed on the first, second, and third loading platform units 5, 5', and 5'' that are in close contact with each other. After that, the link mechanism 8 pushes open the first, third and third loading platform units 5, 5'' and the first and third protruding stoppers 7, 7'' to divide the seedling raising device 12 into three parts, and then The first, second and third unit lifting bars 6, 6' and 6'' lift the first, second and third loading platform units 5, 5' and 5'' to the first, second and third stoppers with protrusions. 7, 7′, 7″, leave them in their original positions and turn them.
The divided seedling raising device 12 is supplied to three seedling boxes a.

(Fig. 3) A vehicle guide plate 10 for a seedling-raising device carrier is provided in front of the trapezoidal frame 1, and a seedling-raising device 1 after being divided is provided at the rear.
A seedling box holder 11 for setting a seedling box a containing 2 is provided. (FIG. 4) The operating order will be explained below.

(1) The seedling grower 12 is transported onto the seedling grower dividing feeder by a seedling grower transport vehicle.

(2) Tilt the handle of the seedling nursery transport vehicle forward and remove the seedling nursery 1.
2 to the first, second and third loading platform units 5, 5',
Place it on 5″.

(3) Due to its own weight, the seedling raising device 12 closes the stopper 7 with the first protrusion, the second stopper with left and right protrusions 7', 7'' third
The stopper with a protrusion is stably stuck into the 7'' protrusion 7a.

(4) When the lever 9 is pushed outward, the link mechanism 8 operates from the state shown in FIG. 2 to the state shown in FIG. 5″ is on the right side (in Figure 1)
, respectively slide outward along the shaft 3. (Fig. 3) Along with this, the first and third stoppers 7,
7'' also slides together with the first and third loading platform units 5 and 5''.

(5) The seedling raising device 12, which is stably placed on the protrusion 7a when sliding, has the first protrusion stopper 7, the second right slide 7', the second left stopper 7'', and the third
It is separated between each of the stoppers 7'' and divided into three parts.

(6) Place the seedling box a in the seedling box receiver 11 in line with the seedling growing device 12 that has been divided into three parts and slid.

(7) Next, tilt the unit lifting lever 9' counterclockwise in FIG. 5a, and operate the link type extension tool 4 so that it is in the state shown in FIG. 5b.

(8) By extending the link type extension tool 4, the shaft 3
rotates, and at the same time the unit lifting bars 6, 6', 6'', which are fixed to the shaft 3,
It is pushed up from the front downward to the rear downward from the base point. (Fig. 5) (9) The loading platform units 5, 5', 5'' set on the unit lifting bars 6, 6', 6'' move forward in the same direction as the unit lifting bars 6, 6', 6''. It _is pushed upward backwards _and downwards from the downward direction. ,
The first and third stoppers 7, 7 are never lifted. Also, Fig. 2 left and right protrusion stopper 7,
7'' is fixed to the second left and right stopper fixing collar _D7 that is integrated with the stand s, so it will not be lifted in the same way.

(10) During this lifting movement, the seedling raiser 12
When the seedlings are detached from the container and reach a certain angle of backward downward inclination, they slide down the carrier unit and are stored in the seedling box a set in the seedling box receiver 11 at the rear of the trapezoidal frame 1. (Fig. 5) (11) When the lifting lever 9' is released, the loading platform units 5, 5', and 5'' return to the forward and downward position due to their own weight, and when the slide lever 9 is returned to its original position, the first and The third loading platform unit 5,5'' slides inward and returns to its original state.

(12) Take out the seedling box a containing the seedling raising device 12 and place it on the stand of the transplanter. . In this way, the divisional feeding operation of the seedling nursery device is completed.

[Effect of idea]
