Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a biochar organic fertilizer spreading machine. Background Art

[0002] Biochar is an organic fertilizer, and its use is increasing. Consequently, the development of biochar spreading equipment is on the agenda. However, due to its high hygroscopicity, biochar easily absorbs water. This absorbs water, significantly increasing its viscosity and decreasing its flowability. When used in spreading operations, the biochar not only adheres to the walls of the hopper, but also clings to each other, making it difficult for the biochar to flow smoothly from the hopper to the spreading components. This results in low spreading efficiency, clogging, and a high failure rate. Furthermore, the amount of biochar to be spread varies depending on the crop and soil conditions, but existing equipment cannot easily accommodate this adjustment, resulting in poor applicability. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of the mechanized operation of biochar spreading, and develop and design a vibration-type biochar variable spreader. By promoting and improving the flow performance of biochar, the purpose of improving the efficiency of mechanized biochar spreading operations, reducing the failure rate of machine spreading operations, and expanding the adaptability of machine operations is achieved.

[0004] The purpose of the invention is achieved as follows: a bearing seat assembly is fixed on the welded lower part of the frame, a driving support shaft of the fixed sprocket is rotatably installed vertically on the bearing seat assembly, a spreading disc is fixed on the upper end of the driving support shaft, an excitation column is supported and fixed on the upper side of the spreading disc, a discharge through-hole is provided in the central part of the excitation disc, N sliding support through-holes are evenly distributed on the circumferential part of the excitation disc located outside the discharge through-hole, the excitation column can be inserted into the sliding support through-hole so as to move axially up and down, a rubber head is fixed on the upper end of the excitation column, a pressure spring is fitted on the excitation column, and the upper and lower ends of the pressure spring are in contact with the rubber head and the excitation disc respectively; a tank body is fixed on the welded part of the frame above the excitation disc, and a tank body is fixed on the A vertical nut is fixed on the upper side of the tank cavity, which is coaxial with the excitation disk. The screw is rotatable and inserted into the nut so as to move up and down. A driven gear and a plunger are respectively fixed on the upper and lower ends of the screw. A blanking hole is opened on the central part of the bottom wall of the tank body, and the plunger is closed or opened in coordination with the blanking hole. A plurality of extrusion protrusions are evenly distributed along the circumferential direction on the outer wall surface of the lower side of the bottom wall of the tank body, and the extrusion protrusions are in contact or out of contact with the rubber head on the excitation column in turn. A feeding hole is opened on the upper wall surface of the tank body, and a motor and a single-chip microcomputer are respectively installed on the welded upper part of the frame. The single-chip microcomputer is connected to the motor by a wire. The driving gear is fixed on the motor, and the driving gear is meshed with the driven gear, thereby forming an exciting biochar variable spreader.

[0013] The following is a detailed description of the implementation scheme of the invention with reference to the accompanying drawings. A vibration-type biochar variable spreader, wherein a bearing seat assembly 13 is fixed on the lower part of the frame weld 7, a driving support shaft 14 of which a sprocket 12 is fixed and rotatably mounted vertically on the bearing seat assembly 13, a spreading disc 11 is fixed on the upper end of the driving support shaft 14, a vibration disc 10 is supported and fixed on the upper side of the spreading disc 11, a discharge hole 15 is provided in the center of the vibration disc 10, N sliding support holes 23 are evenly distributed on the circumference of the vibration disc 10, which is located outside the discharge hole 15, a vibration column 17 is inserted into the sliding support hole 23 so as to be axially movable up and down, a rubber head 8 is fixed on the upper end of the vibration column 17, a pressure spring 9 is fitted on the vibration column 17, and the upper and lower ends of the pressure spring 9 are in contact with the rubber head 8 and the vibration disc 10 respectively; on the frame weld 7, above the vibration disc 10 A fixed tank body 6 is provided, and a nut 19 is fixed vertically on the upper side of the cavity of the tank body 6 coaxial with the exciting disk 10. The screw 4 is rotatably and movably inserted on the nut 19. The driven gear 2 and the plunger 5 are respectively fixed on the upper and lower ends of the screw 4. A blanking through-hole 16 is provided on the central part of the bottom wall of the tank body 6. The plunger 5 is closed or opened in cooperation with the blanking through-hole 16. A plurality of extrusion protrusions 18 are evenly distributed along the circumferential direction on the outer wall surface of the lower side of the bottom wall of the tank body 6. The extrusion protrusions 18 are in contact or out of contact with the rubber head 8 on the exciting column 17 in turn. A feed through-hole 22 is provided on the upper wall surface of the tank body 6. The motor 3 and the single-chip microcomputer 21 are respectively installed on the upper part of the frame weld 7. The wire 20 connects the single-chip microcomputer 31 with the motor 3. The driving gear 1 is fixed on the motor 3, and the driving gear 1 is meshed with the driven gear 2.

[0014] During operation, biochar is fed into the tank body 6 from the feed hole 22, the single chip microcomputer 21 starts the motor 3 to rotate through the wire 20, and the rotating driving gear 1 drives the screw 4 to rotate through the driven gear 2. Under the control of the fixed nut 19, the screw 4 drives the plunger 5 to move up and down in the tank body 6, adjusting the distance between the lower end of the plunger 5 and the blanking hole 16 on the lower wall of the tank body 6, that is, changing the opening and closing size of the blanking hole 16.

The spring 9 rotates, and when the rubber head 8 on the excitation column 17 contacts the extrusion protrusion 18 on the bottom wall of the fixed tank body 6, the excitation column 17 moves downward in the sliding support through hole 23 on the excitation plate 10, and the pressure spring 9 is compressed and the pressure increases. When the rubber head 8 on the rotating excitation column 17 is out of contact with the extrusion protrusion 18, under the action of the pressure spring 9, the excitation column 17 moves upward rapidly, and the rubber head 8 hits the bottom wall of the tank body 6, causing the tank body 6 itself to vibrate. At the same time, the biochar in the tank body 6 falls from the blanking through hole 16 and the discharge hole 15 in turn to the rotating spreading plate 11 and is spread and discharged backward, thereby completing the biochar spreading operation.
