Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a handheld fertilizer hole wall evenly smeared with fertilizer for tobacco transplanting operation and a semi-mechanized fertilizing tool. Background Art

[0002] Before transplanting tobacco seedlings to the field, holes need to be made on the ground first, fertilizers are spread in the holes, and then the tobacco seedlings are transplanted into the holes after fertilization to complete the field transplanting operation. However, due to the shortcomings and defects in the structural design, the existing fertilizer applicator only has the function and effect of shaking the fertilizer into the hole, and the fertilizer dropped is all concentrated at the bottom of the hole. There is no fertilizer on the side wall of the hole from top to bottom, which not only cannot meet and benefit the needs of crop growth stage development, but also has the problems of large fertilizer loss, low utilization efficiency, fertilizer waste, and increased use cost. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the actual needs of the current tobacco seedling field transplanting operations, to study a handheld fertilizer hole wall uniformly distributed fertilizer applicator, so as to achieve the purpose of greatly improving the fertilizer utilization rate, reducing and lowering fertilizer losses and operating costs, and facilitating the growth and development needs of tobacco seedlings.

[0004] The purpose of the invention is achieved in this way: a cylindrical chassis is coaxially fixed on the lower end of the conical fertilizer equalizing body by threaded cooperation, a barrel-type fertilizer box is coaxially fixed on the upper end of the conical fertilizer equalizing body by stud bolt combination, a support plate is coaxially fixed on the upper end surface of the cylindrical chassis, radial support long strip holes are evenly distributed in the circumferential direction on the support plate, an upper cylinder and a lower cylinder are respectively vertically fixed on the upper end surface and the lower end surface of the driving block, the lower cylinder can be radially reciprocatingly inserted into the radial support long strip holes arranged on the support plate, a rotating slot plate is coaxially equipped at the position between the upper part of the driving block and the lower part of the conical fertilizer equalizing body, a large spiral inner hole is provided in the central part of the rotating slot plate, radial drive long strip holes are evenly distributed in the circumferential direction on the rotating slot plate, and the upper cylinder on the driving block can be radially reciprocatingly inserted into the radial drive long strip holes The inner and outer operating rods are vertically inserted in the cylindrical fertilizer box and fixedly assembled with the cylindrical fertilizer box by a screw combination. The inner operating rod is inserted inside the outer operating rod so as to be positioned circumferentially and radially and axially reciprocatingly movable up and down. A disc-shaped piston, a conical piston and a large spiral cylinder are installed on the lower side of the inner operating rod from top to bottom in sequence. The disc-shaped piston and the conical piston are inserted into a closed fit or disengaged from the insertion fit with the fertilizer discharge hole at the bottom end of the cylindrical fertilizer box in sequence. The large spiral cylinder passes through the conical fertilizer equalizing body and is inserted into the large spiral inner hole on the rotating groove plate for rotational driving fit. The threaded rod is laterally inserted into the lower part of the conical fertilizer equalizing body, and the inner end of the threaded rod is screwed and fixed with the internal thread radial hole on the driving block. A smear plate is fixed on the outer end of the threaded rod and located at the lower side of the conical fertilizer equalizing body, thereby constituting a handheld fertilizer hole wall uniform distribution fertilizer spreader.

[0011] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A handheld fertilizer hole wall uniformly distributed fertilizer applicator, a cylindrical chassis 7 is coaxially fixed to the lower end of a conical fertilizer distribution body 4 through threaded cooperation, a cylindrical fertilizer box 12 is coaxially fixed to the upper end of the conical fertilizer distribution body 4 through a stud bolt assembly 3, a support plate 8 is coaxially fixed to the upper end surface of the cylindrical chassis 7, radial support long strip holes 8-1 are uniformly arranged on the support plate 8 along the circumferential direction, and upper cylinders 9-3 and 9-4 are respectively fixed vertically on the upper and lower end surfaces of a driving block 9. The lower cylinder 9-1 can be inserted into the radial support strip hole 8-1 configured on the support plate 8 in a radially reciprocating manner. A rotating groove plate 5 is coaxially mounted between the driving block 9 and the conical fertilizer equalizing body 4. A large spiral inner hole 5-2 is arranged at the center of the rotating groove plate 5. The radial driving strip holes 5-1 are evenly distributed on the rotating groove plate 5 along the circumferential direction. The upper cylinder 9-3 on the driving block 9 can be inserted into the radial driving strip hole 8-1 in a radially reciprocating manner. The outer operating rod 1 is inserted vertically into the cylindrical fertilizer box 12 in the strip hole 5-1, and is fixedly assembled with the cylindrical fertilizer box 12 by the screw assembly 2. The inner operating rod 10 is inserted in the outer operating rod 1 so as to be positioned circumferentially and radially and axially reciprocatably movable up and down. The disc-shaped piston 10-1, the conical piston 10-2 and the large spiral cylinder 10-3 are installed in sequence from top to bottom on the lower side of the inner operating rod 10. The disc-shaped piston 10-1 and the conical piston 10-2 are in sequence with the cylindrical fertilizer box 12. The fertilizer discharge hole at the bottom end of 12 is in an inserted and sealed fit or a disengaged insertion fit, the large spiral cylinder 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 to form a rotational drive fit, the threaded rod 11 is laterally inserted into the lower part of the conical fertilizer equalizing body 4, the inner end of the threaded rod 11 is in a tightened and fixed fit with the internal thread radial hole 9-2 on the driving block 9, and the smear plate 6 is fixed on the outer end of the threaded rod 11, located at the lower side of the conical fertilizer equalizing body 4.

[0012] When in use, fertilizer is filled into the cylindrical fertilizer box 12, and the outer operating rod 1 is lifted by one hand to vertically insert the whole device into the hole for planting rice in the field, and the inner operating rod 10 is pushed downward by the other hand to move it downward in the outer operating rod 1. When the conical piston 10-2 on the inner operating rod 10 escapes from the fertilizer discharge hole at the lower end of the cylindrical fertilizer box 12, the fertilizer stored between the bottom of the disc-shaped piston 10-1 and the top of the conical piston 10-2 is evenly distributed on the conical fertilizer distribution body 4. At this time, the disc-shaped piston 10-1 is located in the fertilizer discharge hole at the lower end of the cylindrical fertilizer box 12, closing it to prevent the fertilizer in the cylindrical fertilizer box 12 from falling. At the same time, the large spiral cylinder 10-3 on the downwardly moving inner operating rod 10 passes through the large spiral on the rotating groove plate 5. The inner hole 5-2 drives the rotating groove plate 5 to rotate, and through the cooperation of the radial driving long hole 5-1 on the rotating groove plate 5 and the upper cylinder 9-3, and under the joint control of the radial supporting long hole 8-1 on the support plate 8 and the lower cylinder 9-1, the driving block 9 is radially expanded and moved outward, and the internal threaded radial hole 9-2 on the driving block 9 causes the smear plate 6 to expand and open radially outward through the threaded rod 11. At this time, the outer operating rod 1 is pulled upward by hand to move the device upward in the hole tube as a whole, and the fertilizer on the surface of the conical fertilizer equalizing body 4 falls on the smear plate 6. The smear plate 6 smears and squeezes the fertilizer from bottom to top on the inner wall surface of the hole to complete the operation; then the inner operating rod 10 is lifted up and returned to the initial position, and the operation is cyclically performed in sequence.
