Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention divides a group of seedlings grown in paper tubes into sizes suitable for loading onto a transplanter or storing in a seedling transport box. This relates to a device that facilitates the handling of paper tube seedling groups by dividing them.

(Conventional technology) A group of paper tube seedlings is a group of paper tubes that are arranged in a honeycomb shape, packed with soil, sown, and watered to raise the seedlings.The individual paper tubes are glued together with water-soluble glue. After watering, the water-soluble glue washes away and is easy to separate. Normally, paper tubes are made quite large in consideration of economic efficiency during production and difficulty in seedling management. For example, in the case of sugar beet seedlings, one paper tube seedling group can weigh more than 60 kg. reach If such a group of large paper tube seedlings is loaded directly into a transplanter, the seedling stand must be made larger than necessary, and if transported in a seedling box, a large seedling box is required and it is difficult for one person to carry them. Since it is inconvenient that it cannot be transported, it is widely practiced to divide it into desired sizes. The conventional dividing method is to connect two plates with a hinge, place a group of paper tube seedlings so that the part to be divided coincides with the connecting line, and then bend the plate and divide it along the connecting line. ing.

(Problems to be solved by the present invention) Even with the above method, not only two or more workers are required to place paper tube seedlings weighing over 60 kg on the dividing plate, but also separation Because it is simply folded, it is simply peeled off, and if there are seedlings with entangled roots or entangled leaves, they must be loosened manually after division. If you try to take out the seedlings without loosening them, the tangled seedlings will attract each other and the paper tube seedling group will become scattered, making it impossible to divide the paper tube seedling group into paper tube seedling groups of the desired size. If you try to transplant such seedlings with a transplanter, the divided parts will have unevenness, which will cause plant loss.

(Means for Solving the Problems) The inventor of the present invention solved the above problems and proceeded to create a device that can be divided into desired sizes by one person.As a result, seedlings with tangled roots or tangled leaves are gradually removed. Focusing on the fact that paper tube joints can be divided along rows without coming apart when pulled apart, a dividing machine was installed in front of a movable member such as a wheel or sled that can move along the ground, and the paper to be divided was created. A plurality of hawk fixing rods are arranged in horizontal rows according to the size of the cylindrical seedling group, and each hawk fixing rod has a large number of hawks fixed in a perpendicular direction so that the paper cylindrical seedling group can be placed on it. , the above-mentioned Hawk fixing rod is of two types, an immovable fixed rod and a movable fixed rod, and the movable Hawk fixing rod is bent by the weight of the paper tube seedling group placed thereon so that it can move laterally. did.

(Function) In the present invention, the hawk is attached in the forward direction of the wheel, so when the tip of the hawk is placed between the paper tube seedling group and the floor surface and the wheel is moved forward, the paper tube seedling group is transferred onto the hawk. . Next, when you lift the whole thing using the wheels as a fulcrum, the immovable Hawk fixing rod will rise, but the movable Hawk fixing rod that is connected to it will be turned down on the other side due to the weight of the paper tube seedling group, so it will not move as it does with conventional splitting machines. Divide along the connecting line. After division, the movable Hawk fixing rod moves in the direction of inclination due to the weight of the paper tube seedlings, so the roots and leaves are gradually untangled, and finally the whole plant is completely separated.

(Example) The present invention will be described with reference to the drawings in a case where a group of sugar beet seedlings grown in a paper tube is divided into three parts. Fig. 1 is an overall side view of the dividing machine of the present invention, Fig. 2 is a front view of main parts,

When the pawls 9, 9 are fixed to the ground with the shift pipes 7, 7 standing up, and the footboard 8 is stepped on, the wheels 1, 1 will move forward. Further, handles 10, 10 are fixed to the splitter mounting plates 5, 5 facing upward, and a connecting rod 12 is provided between the rail bracket support plates 11, 11, and an immovable center hawk fixing rod is provided at the bottom. 13 and fixed so that the whole has a rectangular shape. Pins 14, 14 are provided at the lower ends of the rail bracket support plates 11, 11 at positions where the central fork fixing rod 13 is fixed, and the rail bracket 1 is attached to these pins 14, 14.
The lower ends of the rail bracket support plates 11, 11 are inserted so that the lower ends thereof are opposed to each other, and pins 16, 16 are installed on both upper sides of the rail bracket support plates 11, 11. Elongated holes 17, 17 are provided in the upper portions of the rail brackets 15, 15 facing the pins 16, 16, and the pins 16, 16 are fitted therein in a movable manner. Therefore, rail bracket 1
5 and 15 rotate around a pin 14 located below toward the outside of the rail bracket support plates 11 and 11;
It can reciprocate within the allowable range of the upper elongated holes 17, 17.

On the other hand, the rail bracket support plates 11, 11
Latching claws 18, 18 are provided at the upper end, and the rail bracket 1 faces the latching claws 18, 18.
Pins 19, 19 are provided on 5, 15 to lock the rail brackets 15, 15 in a drawn state at all times.

Each of the rail brackets 15, 15 is provided with a rail 20, 20 having three stages of guide paths, upper, middle, and lower, facing outward, and is fixed with bolts 21, 21, etc., and a connecting plate 22, 22 is attached to the other end. The guide paths 20-A, 20-B, and 20-C are fixed so as to be parallel to each other. Guide path 20-A, 20-B, 20
-C has side hawk mounting plates 23 and 23, respectively.
The upper guide path 20-A is opened upward, the middle guide path 20-B is opened sideways, and the lower guide path 20-C is opened downward. The rolls 24, 24, 24 are made to face each other so that they can move without falling off. Said side hawk mounting plate 2
On the underside of 3, 23 are side hawk fixing rods 25, 2.
5 are provided, and the locking pawls 18, 18 are fixed so that when the rail brackets 15, 15 are locked, they contact both ends of the center fork fixing rod 13 and form a straight line. A large number of hawks 26, 26, . . . are fixed to each of the central hawk fixing rod 13 and the left and right side hawk fixing rods 25, 25 in a perpendicular direction. The lengths of the central hawk fixing rod 13 and the side hawk fixing rods 25, 25 are determined by taking into account the length of the paper cylinder seedling group to be divided and the ratio of dividing. Each length is approximately equal. Also, the length of the hawks 26, 26, . . . is made equal to or slightly longer than the width of the group of paper tube seedlings to be divided.

Next, in the apparatus of the present invention, in order to divide the paper cylinder seedling group without difficulty, there is a gap between the connecting rod 12 and the rail brackets 15, 15, and between the rail brackets 15, 15 and the side fork mounting plates 23, 23. Spring 27, 27 and spring 28, 28 are provided upwardly between them, respectively, and are pulled toward the center. The tensile strength of the springs 27, 28 is balanced so that the side hawk fixing rods 25, 25 remain horizontal when there is no load, and when a group of paper tube seedlings is placed on the hawks 26, 26... It is strong enough to allow the side hawk fixing rods 25, 25 to bend and gradually move toward both sides.
5 may be fixed to both ends thereof to assist in the separation, and the action of the springs 27 and 28 may be performed in place of hydraulic pressure or other devices.

When using the device of the present invention, the latch claw 1

The claws 9, 9 are fixed to the ground with the shift pipes 7, 7 bent. When the footboard 8 is stepped on in this state, the wheels 1, 1 move forward, and the hawks 26, 26, which are fixed via the splitter mounting plates 5, 5, the central hawk fixing rod 13, and the side hawk fixing rods, move forward. It moves forward and invades the lower side of the paper tube seedling group P. When the paper tube seedling group 4 stops advancing at the point where the side part touches each of the hawk fixing rods 13, 25, 25, the paper tube seedling group P is completely attached to the hawks 26, 26.
...It will be placed on top. Next, hold the handle 10 and push it down manually to lift the splitter using the wheels 1, 1 as a fulcrum. At this time, remove the latch claws 18, 18 by an appropriate method and the side hawk 2
The rail bracket support plates 11, 11 rotate toward both sides about the pin 14 against the spring 17 due to the dead weight of the paper tube seedling group P on the paper cylinders 5, 25.
For this reason, the rails 20, 20 are inclined, and the side hawk fixing rods 25, 25 supported by them are also inclined, and the paper tube seedling group P supported by the hawk 26 of the central hawk fixing rod 13 and the side hawk fixing rods 25, 25 are supported. The paper tube seedling group P that is separated is folded and peeled off due to the same action as in a conventional dividing machine. However, since the side fork mounting plates 23, 23 follow the inclined rails 20, 20 and move in the inclined direction against the spring 28, the separated paper tube seedling group P is completely divided into right and left sides.

(Effects) As described above, the present invention allows the hawks 26, 26 to enter the underside of the paper tube seedling group P simply by stepping on the footboard 8, and lifts the whole by simply pushing down the handle 10, making it larger than the conventional method. No effort is required; after lifting, just remove the latch claws 18, 18, and the side hawk fixing rods 25, 25 will tilt due to the weight of the paper tube seedling group P, and as a result, the paper tube seedling group P will be tilted.
peels off from the bent place. Furthermore, after peeling, it moves along the slope of the rails 20, 20, .
