Description

[Detailed description of the invention] This invention relates to an impact soil filling machine used for the inverted soil filling method of seedling raising containers.
A bottomless and uncovered collecting paper tube is spread out on the inversion board corresponding to the seeding hole, packed with soil on top of it and subjected to impact to reach the desired soil packing density, then turned over, the inversion board is removed, and the This is related to a soil filling machine that sows seeds into holes that appeared in .

Conventionally, when growing root vegetables such as beets in a long and narrow paper tube, an impact soil filling machine such as that disclosed in Japanese Utility Model Publication No. 48-41771 is used to uniformly harden the entire length of the long and thin paper tube. The soil is filled with earth and seeds are sown in the upper space created by the impact. However, this method has the inconvenience that the depth of the upper space varies depending on the quality of the soil to be filled or the degree of impact, so the seeding depth may become deeper or shallower. For this purpose, a paper tube is spread out in advance on a base plate with protrusions corresponding to the depth of the sowing depth, and a full paper tube is filled with soil.After filling, the paper tube is turned over and the base plate with protrusions is removed to reach the seeding depth. There are known methods for forming . It has been known for a long time that this method is carried out using the equipment disclosed in the above-mentioned Publication of Utility Model Publication No. 48-41771. This caused the inconvenience of not being able to work alone and having to work in groups of several people. A method of mechanizing the above-mentioned work has also been considered, but this method has the disadvantage of being expensive because it requires a separate turning machine in addition to the soil filling machine.

The inventor of this invention conducted research to create an inexpensive device that would save workers' labor and allow them to work efficiently.As a result, the up and down movement mechanism of the impact soil filling machine is a link mechanism as before. The seedling-raising container holding mechanism placed above is removably engaged with the link mechanism by a fitting shaft provided on the lower bottom plate of the mechanism, and furthermore, on both sides of the seedling-raising container holding mechanism, there are horizontal holding frames for holding down both sides of the seedling-raising container. The frame is configured to be openable and closable, and one side of the horizontal press frame is provided with a vertically rolling fulcrum, and a reversing table is fixed to the side of the link mechanism to prevent the horizontal press frame from rolling. By creating a device that can be stopped and rolled, it was possible to roll it sideways and turn it around after impacting the earth.

To explain the present invention with a diagram, reference numeral 1 denotes a machine frame of an impact machine link mechanism, and the lower end of an arm 3 is supported by a shaft 2 at the front and rear lower portions of both sides of the machine frame 1, and the upper end of the arm 3 and , the lower end of the upper arm 4 is connected by a shaft 5, and both ends of the front and rear shafts 5, 5 are connected to a connecting rod 6.
A long hole 7 is bored in the middle of the connecting rod 6. Further, an upper connecting rod 9 is pivotally attached between the upper arms 4, 4 by a shaft 8 to form a link mechanism, and both side link mechanisms are fixed by horizontal rods 10, 10. Then, a shaft 11 is rotatably provided at the intermediate lower part of the first side of the machine frame 1, a lower part of a handle 12 is pivotally attached to the shaft 11, and a pin 13 is provided on the lower side of the handle 12 to connect the Loosely fit into the long hole 7 of the rod 6. Further, one end of a lateral movement regulating rod 14 is connected to the end of the shaft 8 on which the one arm 4 is pivoted, and the other end of this regulating rod 14 is connected to the upper end of the machine frame 1 by a shaft 15. There is. Therefore, when the handle 12 is moved left and right, the link mechanism rises through the elongated hole 7 and quickly falls after passing the center.

On the other hand, a seedling-raising container holding mechanism is placed on the link mechanism, and the seedling-raising container holding mechanism consists of a mounting plate 19 provided on the bottom plate 16 and horizontal holding frames 20, 20, 20' provided at the four corners of the mounting plate 19. , 20' and horizontal presser frame 2
A pair of upper presser rods 2 spanned between 0 and 20'
6 and 26, and a seedling growing container 38 is housed and held within the space constituted by them. The mounting plates 19, 19 are fixed to the bottom plate 16 using a fitting shaft 1 provided approximately on the center line of the bottom plate 16.
The fitting shaft 17 is fixed by the mounting plate 19.
It passes through and extends further downward to fit into holes 18 provided in the horizontal rods 10, 10 of the link mechanism. Further, both the front and rear sides of the mounting plate 19 are bent, and the shafts 21 and 21' are fixed to the four corners of the bent parts.
The horizontal holding frames 20, 20' are each rotatably attached to this. In order to facilitate its rotation, a protrusion 22 is installed on the side of the horizontal holding frame 20', and one end of the protrusion 22 is fixed to the mounting plate 19 by a spring 23. Further, in order to hold down the seedling growing container 38 stored in the space, a holding plate 24 is fixedly stretched between the horizontal holding frames 20, 20 and 20', 20', and the horizontal holding frames 20, 20' facing each other are fixed. An upper presser rod 26 is provided between each, but the upper presser rod 2
The horizontal presser frame 20 side of 6 is rotatably attached to the shaft 25, and the side presser frame 20' side is attached to the upper presser lock metal fitting 2.

A fulcrum hole 35 is placed on the inversion table 31 at an interval of the shaft 25.
, and its extension is approximately horizontal.

The device of the present invention has the above-mentioned configuration, and its operation will now be described. The paper cylinder protrusion plate 37, which has protrusions 36 of the same pitch as the pitch when the collecting paper cylinder 38 is unfolded, is placed on the bottom plate 16. Then, the fitting shaft 17 of the bottom plate 16 is fitted into the hole 18 of the horizontal rod 10. Next, the paper tube 38 is unfolded and inserted into each of the protrusions 36 of the protrusion plate 37. As a result, the paper cylinder 38 is fixed to the protrusion plate 37, so it is placed on the bottom plate 16,
When the left and right horizontal holding frames 20, 20' are raised, the left and right sides of the paper cylinder 38 are firmly held down by the holding plates 24. Next, extend the upper presser rod 26 to the opposite side and securely fix it with the upper presser lock fitting 28. When this work is completed, the paper cylinder 38 is attached to the bottom plate 16.
Since it is fixed on top, fill it with soil and move the handle 12 from side to side. At this time, the effect of the elongated hole 7 causes the base plate 16 to be lifted until the arms 3 and 4 are aligned in a straight line, and after passing that position, it rapidly falls and collides with the machine frame 1. Repeat this several times and when the soil is compacted, a void will be created in the upper part, so the soil will be compressed again into the paper tube 38.
The above-mentioned operation is repeated to obtain a predetermined hardness. When the earth filling work is completed, the upper holding lock fitting 28 is immediately disengaged to level the surface, and the lower plate 39 is placed on top of it and then locked again. Next, leave the bottom plate 16 as it is on the inversion table 31.
direction to drop the shaft 21 into the fulcrum hole 34, and then tilt it further to drop the shaft 25 into the fulcrum hole 35. When the bottom plate 16 is further lowered onto the horizontal portion of the inversion table 31, the paper tube 38 is turned upside down and placed on the inversion table 31 with the bottom plate 16 facing upward. Therefore, when the lock fitting 28 is released and the upper presser rod 26 is released, the bottom plate 1 is released.
6 is in a free state. Therefore, when the bottom plate 16 is removed and the projection plate 37 is removed, a seeding hole appears on the upper surface of the paper cylinder 38. The work is completed when the seeds are sown in the seeding hole and covered with soil, and the operator holds both ends of the bottom board 39 and carries it to the desired seedling-raising location to raise the seedlings.

The present invention is made as described above, and since it is rolled and reversed after filling the soil, it requires about half the force of the conventional method, and there is no need to use a special reversing machine, and the device is simple and can be provided at low cost. It has advantages.
