Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a soil block manufacturing apparatus, and more particularly to a soil block manufacturing apparatus in which the thickness of the soil block can be selected and set according to the application.

[Conventional technology]

Soil block is a method in which seeds or young seedlings are applied to each plant and grown to the required size.
After growing, the seedlings can be transplanted to the field without changing the root environment, which allows the seedlings to grow well.
It is used in a cultivation method that has recently been in the spotlight. In order to form this soil block accurately and efficiently, there is a belt conveyor that is attached to the machine frame and is fed intermittently, a soil hopper that is arranged along the feeding direction of the conveyance section of this belt conveyor, and a soil hopper that is arranged along the feeding direction of the conveyance section of this belt conveyor. A cutter is provided adjacent to the soil hopper to cut the soil supplied onto the belt conveyor from the soil hopper into a plurality of independent blocks, and a push spring is provided before and after the cutter in the feeding direction of the conveyor belt. A soil block manufacturing apparatus comprising a block presser which has a pressing habit on the block side and is integrally attached to a component of the cutter via a pressure spring and starts upward movement after a delay after the cutter starts upward movement. is proposed.

[The problem that the idea attempts to solve]

In such a soil block manufacturing apparatus, it is preferable that the thickness of the soil block can be appropriately selected depending on its use. However, in the forming parts that have been proposed so far, the forming part that compacts the soil is suspended by a spring from a slide block that supports and fixes the cutter, and in the final stage of compaction, the thickness is adjusted according to the amount of descent of the slide block. is uniquely defined. Therefore, if the depth of cut with the cutter was constant, the thickness of the soil block was also constant.

The present invention has been made to solve the above problems.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a belt conveyor that is attached to the machine frame and is fed intermittently;
A soil hopper is arranged along the feeding direction of the conveyance section of the belt conveyor, and a soil hopper is provided adjacent to the soil hopper to cut the soil supplied onto the belt conveyor from the soil hopper into a plurality of independent blocks. and a cutter which is placed before and after the cutter in the feeding direction of the conveyor belt and which has the tendency to press against the block side with a pressure spring, and which is integrally attached to the constituent members of the cutter via a pressure spring. In a soil block manufacturing device equipped with a block holder that starts the upward movement after a delay, the forming plate for forming the soil block to a predetermined thickness is held against the vertically movable slide block to which the cutter is attached using a spring. The present invention is characterized in that a stopper for suspending and regulating the amount by which the molded plate is pushed up is provided on the slide block side so as to be adjustable up and down.

[Effect]

With the above structure, the present invention suspends the molding plate for molding the soil block to a predetermined thickness with a spring against the vertically movable slide block to which the cutter is attached, and regulates the amount by which the molding plate is pushed up. By providing a vertically adjustable stopper on the slide block side, the molding thickness of the soil block by the molding plate can be selected and set even though the amount of descent of the slide block is constant and a predetermined cut is made.

A torsion spring 82 is provided at the pivot portion 37a to the underframe 37.

Next, the operation of this soil block manufacturing apparatus will be specifically explained. First, soil suitable for the soil block is stored in the soil hopper 35, and a certain amount of soil is allowed to flow out from the soil supply port 36 onto the belt 16 of the conveyor. When the motor 25 is driven in this state, the lever 31 swings through the interlocking rod 29 by cranking, and the ratchet wheel 15 is intermittently driven through the ratchet pawl 34. The rotation of the ratchet wheel 15 drives the pulley 13 coaxial therewith, and the belt 16 is intermittently fed. Since the stroke of this intermittent feed determines the width dimension of the block to be molded, it can be adjusted to some extent by selecting the fixing position of the interlocking rod 29 relative to the lever 31 (movement within the slit 32). Since the belt 16 moves on the bottom surface of the soil hopper 35 by intermittent feeding of the belt 16, soil is taken out from the soil supply port 36. An anson 46 is provided near this soil supply port 36, and since it swings in an arc in conjunction with the motor 25, it scrapes out the soil flowing out from the soil supply port 36 and lifts it up. It works to press from the top.

In this case, since the above-mentioned Yasuson 46 has an auxiliary Yasuson 46c extending rearward, the soil is temporarily raked out far behind the Yasuson 46, so that the soil can be scraped out from the supply port 36 to the back of the Yasuson 46. This prevents the soil from collapsing and leaning against itself in advance, preventing it from becoming too compact.

Also, the slide block 5 is connected via the crank 41.
3 and 56 move up and down. First, block 53
A forming plate 63 provided on the belt 16 compacts the soil on the belt 16. This pressing force is automatically adjusted by the elastic force of the spring 69 against the forming plate 63, and stops at the position where it hits the stopper 72, so that the thickness of the soil block is set. At the same time, the soil blocks in front and behind the cutter 61 are cut, and the soil block on the front side of the cutter 61 is cut in the width direction by the cutter 62. At the same time, the punch 71 forms a slot in the center of the upper surface of the cube-shaped block. Next, the slide block 53 rises, the cutters 61 and 62 rise, and the punch 71 also rises, but the holding plate 64 and the forming plate 63 do not rise at this stage. This is next spring 70
and remains on the block until suspended at 69.
Therefore, when the cutters 61 and 62 leave the block, they do not take the soil block with them.

The block, which is slotted and shaped into a regular cube, receives seeds that are intermittently supplied from the nozzle 76 in conjunction with the operation of the gate plate 79.

In this case, when the gate plate 79 rises, one seed is placed in the through hole 79a and lifted, so when the through hole 79a matches the supply port 74, one seed is placed in each of the hoses 75. It will be in the form of supply. For this purpose, the seed supply device 73 has a weir plate 7.
3a is working effectively.

[Effect of idea]

As detailed above, the present invention suspends a molding plate for molding a soil block to a predetermined thickness with a spring against a vertically movable slide block to which a cutter is attached, and regulates the amount by which the molding plate is pushed up. Since a stopper is provided on the slide block side that can be adjusted vertically, the thickness of the soil block can be easily and reliably selected even under conditions where the vertical stroke of the slide block is constant and the cut into the soil block by the cutter is constant. Can be configured.

Therefore, it is possible to easily obtain a soil block with a thickness suitable for the intended use, improve crop compatibility, and raise seedlings without waste.
