Description

[Detailed Description of the Invention] The present invention relates to a dividing transporter for a seedling-raising paper tube assembly used in beet transplant cultivation.

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 with a width of 30 cm, a length of 120 cm, and a height of 13 cm, and weighs about 60 kg.

A transplanter is used to transplant this seedling-raising paper cylinder to the main field.

This transplanter has a seedling mounting stand, and this stand is
The width is 40cm, and the 40cm wide seedling box is set just right.

By the way, as mentioned above, the length of the paper tube assembly is
Since the length of the aggregate is 120 cm, when placing it on the pedestal, the length of the aggregate is divided into 1/3 pieces to match the width of the seedling box of 40 cm and placed on the transplanter.

Conventional seedling division work involves manually inserting a fork under the seedling, pulling it diagonally upwards and lifting it.
It is divided and transported. Because this work of transporting in parts is hard work, it is the responsibility of adult men, and during transplantation, men must be responsible for two tasks: driving the transplanter and transporting the parts in parts.

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

The purpose of the present invention is to solve the problems of the conventional dividing work of paper tubes for raising seedlings. That is, the present invention mechanizes the conventional manual work of dividing seedling paper cylinders, and enables the series of operations to be carried out continuously, including the transplanting operation.

Embodiments of the present invention illustrated in the drawings will be described below.

(Description of Embodiments) In the drawings, 1 is a horizontal frame 1 of the split transporter of the present invention, 2 is a portal frame fixed to the horizontal frame 1, 3 is a handle frame, and 3a is the rotation of the handle frame 3 having a groove 3b. The shaft, 4 is a rear stopper, and 5 is a front stopper. The front stopper 5 is provided to maintain the upright position of the handle frame 3 during the dividing operation. The rotation shaft 3a of the handle frame 3 is accommodated between the front stopper 5 and the rear stopper 4,
The lower end of the handle frame 3 is rotatably mounted in the groove 3b.

6 is a link mechanism mainly consisting of a dogleg-shaped link l that connects box b to the upper end, _l1 is the lower bent part of link l, _l2 is the upper bent part, and 7 is a receiving plate that serves as the fulcrum of the lower end of link l. , 8 fixes the box b to the lower end and uses a lever interlocking with the link mechanism 6 to connect the lever fulcrum 19.
It can be bent into a dogleg shape. Reference numeral 9 denotes a protruding rod that protrudes from the lever 8. As will be described later, when the handle frame 3 is upright, it is located on the front side of the gate-shaped frame 2 (position indicated by the dotted line in Figure 4), and is located at the front side of the lever 8 in b○ in Figure 2. It is impossible to return from the position to the position a○ in Figure 2.

When the handle frame 3 is in the inclined position shown by the solid line in FIG. 4, the protrusion 9 collides with the wheel mounting plate 13, and the lever 8 cannot slide from the position a○ in FIG. 2 to the position shown in FIG.

Reference numeral 10 denotes a guide for the link 1 fixed to the handle frame 3, the function of which will be described later.

11 is a lever slide guide integrated with the handle frame 3, 12 is a seedling fork fixed to the horizontal frame 1, 13 is a mounting plate on both sides of the wheel 14, and 15 is a seedling fork stepping bar, which is located behind the wheel mounting plate 13. They are arranged in a U-shape. 16 is a seedling extrusion board, 1
7 is a seedling pushing horizontal link mechanism for pushing the seedling pushing plate 16 forward; by stepping on the seedling pushing bar 18 with your foot as shown in FIG. 5, the seedling pushing link mechanism 17 moves from the solid line position to the dotted line The seedling pushing plate 16 is pushed out in the direction of arrow a in FIG.

19 is a lever fulcrum fixed to the handle frame 3, the function of which will be described later. Reference numeral 20 denotes a spring having one end fixed to the wheel mounting plate 13 and the other end fixed to the seedling pushing plate 16, as shown in FIG.
6 in the direction opposite to arrow a in Figure 5. 21 is a paper tube aggregate of grown seedlings.

Next, the operation of the present invention will be explained.

(Explanation of function) First, align the desired dividing position of the paper cylinder assembly 21 for growing seedlings, and then move the horizontal frame 1 and seedling fork 1.
2 to the ground.

Next, step on the seedling fork tread bar 15 with your foot, insert the seedling fork 12 into the lower surface of the paper cylinder assembly 21, push the handle frame 3 forward and upward, and hit the front stopper 5 to a vertical position. Stop with.

That is, the lower end of the handle frame 3 collides with the front stopper 5, and the position of the collision becomes perpendicular to the ground.

Next, the handle frame 3 is supported with the left hand, and the lever 8 is slid from left to right in the lever thrust guide 11 using the lever fulcrum 19 as a fulcrum with the right hand.

That is, from the position of lever 8 in Figure 2 to the second
Slide it to the position shown.

By the way, when the lever 8 shown in FIG. 2 is not slid, the upper bent part _l2 of the link l is inclined outward with respect to the handle frame 3, and the lower bent part _l1 is in a vertical state.

Next, when the lever 8 is slid to the position shown in FIG. 2, the lower bent portion _l1 is guided by the guide 10 fixed to the handle frame 3, and the horizontal frame
It is displaced outward from the handle frame 3 from a vertical state to an inclined state while protruding further downward.
Conversely, the upper bent portion _l2 is displaced from the inclined state to the vertical state towards the handle frame 3. As a result, the horizontal frame 1 is floated obliquely upward in the direction of inclination of the lower bent portion _l1 .

The distance L between the outer end of the receiving plate 7 and the outer end of the horizontal frame 1 in FIG. 2 is expanded to (L+d),
The horizontal frame 1 will rise diagonally upward.

By continuously operating the link mechanism 6 as described above, the series of paper tube assemblies 21 are lifted up while being pulled apart diagonally laterally, so that they can be easily divided at any desired position.

Note that at this time, the protrusion 9 is located at the front of the gate-shaped frame 2, and does not prevent the lever 8 from sliding. If you try to turn the lever 8 before the handle frame 3 is upright, the lever 9 will hit the wheel mounting plate 13 or the portal frame 2.
Lever 8 cannot be rotated.

Also, if the lever 8 is rotated when the handle frame 3 is not upright but tilted forward,
The receiving plate 7 does not touch the ground stably, and the horizontal frame 1 and the fork 12 are not efficiently floated. It is best to fix the handle frame in an upright position.

When the dividing operation of the paper tube assembly 21 is completed, return the lever 8 to the position shown in FIG.
Push down toward you. Finally, the horizontal frame 1 and the fork 12 are lifted off the ground using the wheels 14 as fulcrums, and are transported by running.

When the divided transporter of the present invention travels to a predetermined point, step on the seedling push-out step bar 18, and the seedling push-out horizontal link mechanism 17 moves from the solid line position to the dotted line position in Figure 5, and the seedling push-out plate 16 is divided. The paper tube assembly 21 is pushed out to the destination point.

When the extrusion of the paper tube assembly 21 is completed and the foot is released from the seedling extrusion bar 18, the seedling extrusion plate 16 returns to the solid line position in FIG. 5 due to the elastic force of the spring 20.
One cycle of work is completed.

(Effects of this invention) The effects of the present invention will be summarized below.

a○ Since the work of dividing the paper tube assembly 21 can be carried out using a dividing transporter that also serves as a transporter, it has become possible to save labor in the work of transplanting grown seedlings.

The paper cylinder assembly 21 can be divided by simply moving the lever 8 left and right, making it easy for even women and children to handle.

c○ The paper tube assembly 21 can be divided and transported by simply adding a lever 8, a link mechanism 6, a receiving plate 7, and stoppers 4 and 5 to a conventional transplanting machine, so it is possible to divide and transport the paper tube assembly 21 without increasing the cost. , can carry out both tasks.

Since the link L has a dogleg shape, the horizontal frame 1 is linked with the lever 8 and uses the receiving plate 7 as a fulcrum.
float diagonally upward.

Therefore, the paper tube assembly 21 can be divided by tearing it.
