Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a soil block manufacturing apparatus, and more particularly to a soil block manufacturing apparatus that includes an operation of drilling slots for seeding in formed and cut soil blocks.

[Conventional technology] Soil blocking 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. Soil block manufacturing equipment is used to form soil blocks accurately and efficiently, and includes, for example, a belt conveyor that is attached to a machine frame and feeds the soil intermittently, and a belt conveyor that is attached to a machine frame and conveys the soil intermittently. a soil hopper placed next to the soil hopper; a cutter placed adjacent to the soil hopper for cutting the soil supplied from the soil hopper onto the belt conveyor into a plurality of independent blocks; The cutter is placed at the front and rear of the cutter and has the habit of pressing against the block side with a pressure spring, and is integrally attached to the component of the cutter via a pressure spring, so that the cutter starts to move upward with a delay after the cutter starts moving upward. A device equipped with a block presser foot has been proposed.

[The problem that the idea aims to solve]

In this type of soil block manufacturing equipment, slots for sowing are formed in each cube-shaped soil block by a punch, but the pitch of the intermittent feed of the belt conveyor is If the length of the soil block actually cut out in the conveying direction changes due to misalignment or sliding of the soil on the belt conveyor, or if the thickness of the soil block changes due to adjustment of the pressure by the forming plate, the above-mentioned problems may occur. The slot may be formed off-center in the soil block, or the slot may be at an incorrect depth. This is not only due to the machine side or the quality of the soil, but also due to various conditions such as when it is better to change the depth of the trench depending on the season.

[Means and actions for solving problems]

This invention was made based on the above circumstances,
The soil block is equipped with a mounting member that holds punches arranged at predetermined intervals in the lateral direction for forming slots for seeding, and the mounting member is mounted so that it can be adjusted vertically and longitudinally with respect to the vertically movable slide block. By having such a structure, it is possible to obtain a soil block manufacturing apparatus which can form a seeding groove at the appropriate depth and center of the soil block even under changing conditions.

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.

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. Preventing the soil from collapsing and leaning back will prevent 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 top 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.

In this case, if the width of the soil block in the feeding direction becomes narrow due to deviations in the intermittent feed pitch of the belt conveyor, soil slippage on the belt 16 due to soil quality, etc., loosen the locking nut 82 and remove the slit. Adjust the bolt 81 by moving it back and forth within 68a,
Thereafter, the fixing nut 82 is tightened to fix the mounting member 83. Further, when the thickness of the soil block is changed by adjusting the stopper 72, the position adjusting nut 80 is moved and the stop nut 82 is tightened to change the level of the mounting member 83. This allows the punch 71 to form the slot at the appropriate position and depth.

A slotted, cubically shaped block receives seeds supplied intermittently from a nozzle 76 in conjunction with the operation of a 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 described in detail above, the present invention is equipped with a mounting member that holds punches for forming grooves for seeding in a soil block arranged at predetermined intervals in the lateral direction, and the mounting member is arranged vertically with respect to a vertically movable slide block. Since it is adjustable and can be installed front and back, the position of the punch can be adjusted easily and reliably even when changing the intermittent feed pitch using a belt conveyor, or changing the size or thickness of the soil block. The seeding grooves can be formed in the soil block at the correct position and depth at all times.

Furthermore, when changing the size of the soil block, the attachment members for the cutter and punch can be replaced with ones of the desired pitch.
