Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and mainly relates to a handheld semi-mechanized fertilization tool for tobacco transplanting, which evenly applies fertilizer to the walls of fertilizer holes. Background Technology

[0002] Before transplanting tobacco seedlings into the field, holes need to be drilled in the ground, fertilizer is then applied into the holes, and the seedlings are transplanted into these holes to complete the transplanting process. However, due to deficiencies and defects in structural design, the current fertilizer applicators only have the function of shaking fertilizer into the holes. All the fertilizer is concentrated at the bottom of the hole, leaving no fertilizer on the side walls from top to bottom. This not only fails to meet the needs of crop growth but also results in significant fertilizer loss, low efficiency, fertilizer waste, and increased operating costs. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in light of the actual needs of current tobacco seedling transplanting operations, to develop a handheld fertilizer applicator that evenly distributes fertilizer throughout the hole walls, thereby significantly improving fertilizer utilization, reducing fertilizer loss and operating costs, and benefiting the growth and development of tobacco seedlings.

[0004] The objective of this invention is achieved as follows: A cylindrical base is coaxially fixed to the lower end of a conical fertilizer equalizer via a threaded connection; a cylindrical fertilizer box is coaxially fixed to the upper end of the conical fertilizer equalizer via double-ended bolts; a support plate is coaxially fixed to the upper surface of the cylindrical base; radial support elongated holes are evenly distributed along the circumference of the support plate; an upper cylinder and a lower cylinder are vertically fixed to the upper and lower surfaces of a drive block, respectively; the lower cylinder can be radially reciprocated and inserted into the radial support elongated holes on the support plate; a rotating slot plate is coaxially mounted between the upper part of the drive block and the lower part of the conical fertilizer equalizer; a large spiral inner hole is provided at the center of the rotating slot plate; radial drive elongated holes are evenly distributed along the circumference of the rotating slot plate; the upper cylinder on the drive block can be radially reciprocated and inserted into the radial drive elongated holes. The inner and outer control levers are vertically inserted into the cylindrical fertilizer tank and fixed to it as a whole by screws. The inner control lever is inserted inside the outer control lever, which is circumferentially and radially positioned and axially movable up and down. On the lower part of the inner control lever, a disc-shaped piston, a conical piston, and a large spiral cylinder are installed sequentially from top to bottom. The disc-shaped piston and the conical piston are inserted into the fertilizer discharge hole at the bottom of the cylindrical fertilizer tank in a closed-fitting or disengaged-fitting manner. The large spiral cylinder passes through the conical fertilizer equalizer and is inserted into the large spiral inner hole of the rotating slot plate for rotational drive. The threaded rod is inserted laterally into the lower part of the conical fertilizer equalizer. The inner end of the threaded rod is screwed into the radial hole of the internal thread on the drive block for a fixed fit. A coating plate is fixed on the outer end of the threaded rod, located on the lower part of the conical fertilizer equalizer. This constitutes a handheld fertilizer hole wall uniform coating fertilizer applicator.

[0005] This invention fundamentally solves the problem of applying fertilizer to the walls of holes in the field for transplanting tobacco seedlings, which is impossible in existing technologies. It features a novel, unique, simple, and reasonable structure, high fertilizer utilization efficiency, good fertilizer-saving effect, and is conducive to meeting the growth and development needs of tobacco seedlings.

[0011] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A handheld fertilizer applicator with uniformly distributed fertilizer distribution on the wall of a fertilizer hole comprises a cylindrical base 7 coaxially fixed to the lower end of a conical fertilizer distribution body 4 via a threaded connection; a cylindrical fertilizer box 12 coaxially fixed to the upper end of the conical fertilizer distribution body 4 via a double-ended bolt assembly 3; a support plate 8 coaxially fixed to the upper surface of the cylindrical base 7; radially distributed elongated support holes 8-1 along the circumference of the support plate 8; and cylindrical cylinders 9-3 and 9-3 vertically fixed to the upper and lower surfaces of a drive block 9, respectively. The lower cylinder 9-1 is radially reciprocating and can be inserted into the radially supporting elongated hole 8-1 disposed on the support plate 8. A rotating slot plate 5 is coaxially mounted between the upper part of the drive block 9 and the lower part of the conical uniform body 4. A large spiral inner hole 5-2 is provided at the center of the rotating slot plate 5. The radially driving elongated holes 5-1 are evenly distributed on the rotating slot plate 5 along the circumferential direction. The upper cylinder 9-3 on the drive block 9 is radially reciprocating and can be inserted into the radially driving elongated hole 8-1. Inside the slot 5-1, the outer operating lever 1 is vertically inserted into the cylindrical fertilizer tank 12 and is fixed to the cylindrical fertilizer tank 12 as a whole by screw assembly 2. An inner operating lever 10 is inserted inside the outer operating lever 1, positioned circumferentially and radially, and axially movable up and down. On the lower side of the inner operating lever 10, a disc-shaped piston 10-1, a conical piston 10-2, and a large helical cylinder 10-3 are sequentially installed from top to bottom. The disc-shaped piston 10-1 and the conical piston 10-2 are then connected to the cylindrical fertilizer tank. The fertilizer discharge hole at the bottom of the 12 is either inserted and sealed or disengaged from the insertion. The large spiral column 10-3 passes through the conical fertilizer equalizing body 4 and is inserted into the large spiral inner hole 5-2 on the rotating groove plate 5 in a rotational drive engagement. The threaded rod 11 is inserted laterally into the lower part of the conical fertilizer equalizing body 4. The inner end of the threaded rod 11 is screwed and fixed to the internal thread radial hole 9-2 on the drive block 9. The coating plate 6 is fixedly installed on the outer end of the threaded rod 11 at the lower part of the conical fertilizer equalizing body 4.

[0012] During operation, fertilizer is filled into the cylindrical fertilizer tank 12. Using one hand, the outer control lever 1 is held upright and inserted into the pre-drilled planting hole in the field. The other hand pushes down the inner control lever 10, causing it to move downwards within the outer control lever 1. When the conical piston 10-2 on the inner control lever 10 disengages from the fertilizer discharge hole at the lower end of the cylindrical fertilizer tank 12, the fertilizer stored between the lower part of the disc-shaped piston 10-1 and the upper part of the conical piston 10-2 is evenly distributed onto the conical fertilizer equalizer 4. At this time, the disc-shaped piston 10-1 is located within the fertilizer discharge hole at the lower end of the cylindrical fertilizer tank 12, sealing it and preventing the fertilizer inside the cylindrical fertilizer tank 12 from falling. Simultaneously, the large spiral column 10-3 on the downward-moving inner control lever 10 passes through the large spiral on the rotating groove plate 5. The inner hole 5-2 drives the rotating slot plate 5 to rotate. Through the cooperation of the radial drive elongated hole 5-1 on the rotating slot plate 5 and the upper cylinder 9-3, and under the joint control of the radial support elongated hole 8-1 on the support plate 8 and the lower cylinder 9-1, the drive block 9 moves outward radially. The internal threaded radial hole 9-2 on the drive block 9 causes the coating plate 6 to expand outward radially through the threaded rod 11. At this time, the outer operating lever 1 is pulled upward by hand to move the whole device upward in the hole cylinder. The fertilizer on the surface of the conical fertilizer body 4 falls onto the coating plate 6. The coating plate 6 applies and presses the fertilizer from bottom to top to cover the inner wall of the hole, completing the operation. Then the inner operating lever 10 is lifted to return to the initial position, and the operation is repeated in a cycle.
