Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and mainly relates to a mixing and preparation device for a composting agent in which the mixing ratio of two liquid raw materials can be adjusted. Background Technology

[0002] Straw composting agents are highly efficient biological agents. In straw return operations, the use of composting agents not only accelerates the composting speed of straw in the field, but also significantly improves the degree of straw composting within the same time frame compared to straw without composting agents. Therefore, with the promotion and application of reduced tillage or no-till farming techniques, the demand for straw composting agents is rapidly increasing.

[0003] Traditional methods for preparing straw composting agents rely on manual proportioning and mixing, which suffers from technical problems and drawbacks such as poor proportioning accuracy, low preparation efficiency, and difficulty in guaranteeing product performance. To address these issues, equipment for producing and processing straw composting agents has been developed in recent years, such as mixing devices for nitrogen-containing organic materials and quantitative spreading devices for straw composting agent mixtures. However, due to limitations in their structural design, these devices cannot handle the mixing and proportioning of liquid composting agents made from wheat bran water and yogurt, exhibiting poor adaptability. Summary of the Invention

[0015] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A liquid composting agent mixing device with adjustable ratio of two raw materials includes motors 23 symmetrically mounted on both sides of the bottom end of a device frame assembly 9. A mixing tank 33 is mounted on the upper middle part of the device frame assembly 9. A bevel gear C22 is fixed to the motor shaft 24 of the motor 23. Guide shafts 10 are vertically parallel to each other and fixed on the device frame assembly 9 above the motors 23. Reversing springs 12 are respectively fitted on the upper and lower sides of the guide shafts 10. The upper end face of the upper reversing spring 12 and the lower end face of the lower reversing spring 12 are axially positioned on the guide shafts 10. Radial and circumferential positioning is achieved on the guide shafts 10 between the upper and lower reversing springs 12. A sliding frame 15 is mounted vertically. The upper and lower end faces of the sliding frame 15 are respectively in compression contact or disengagement contact with the reversing springs 12 on the upper and lower sides. A storage tank 14 is fixedly installed on the inner end of the sliding frame 15. On the device frame assembly 9, at the outer part of the motor shafts 24 of the two motors 23, spiral shafts 16 are vertically parallel to each other and rotatably mounted. The threaded holes on the outer end of the sliding frame 15 are rotatably fitted onto the spiral shafts 16, connecting the sliding frame 15 and the spiral shafts 16. On the bottom side of the spiral shaft 16, a bevel gear A17, a lower end face pointed tooth bushing 18, an upper end face pointed tooth bushing 20, and a spiral gear A17 are sequentially mounted from top to bottom, radially positioned, circumferentially rotatable, and axially slidable. The bevel gear B21, with its lower end face pointed tooth bushing 18 and upper end face pointed tooth bushing 20 respectively fixedly integrated with bevel gear A17 and bevel gear B21. A double-end face pointed tooth sleeve 19 is fixedly installed on the spiral shaft 16, located between the lower end face pointed tooth bushing 18 and the upper end face pointed tooth bushing 20. The double-end face pointed tooth sleeve 19 is in a circumferential locking engagement with the lower end face pointed tooth bushing 18 and the upper end face pointed tooth bushing 20, or in a disengaged engagement engagement. The bevel gear C22 meshes with bevel gear A17 and bevel gear B21 respectively. A cylindrical stop slider 11 is axially and radially positioned and circumferentially rotatable on the upper end of the spiral shaft 16. The cylindrical stop slider 11 is axially and radially positioned and circumferentially rotatable. The cylindrical stop slider 11 is slidably mounted in a groove on the upper part of the device frame assembly 9. Two annular grooves are arranged parallel to each other from top to bottom on the outer surface of the cylindrical stop slider 11. A locking spring 31 and a locking steel ball 30 are installed in the groove on the upper part of the device frame assembly 9. The locking spring 31 presses the locking steel ball 30 into the two annular grooves of the cylindrical stop slider 11. Sleeves 8 are fixedly installed on the upper end of the device frame assembly 9, on opposite sides of the mixing tank 33. The variable column 6 is movably inserted into the sleeve 8. The variable spring 7 is fitted on the variable column 6. The upper end of the variable spring 7 is axially positioned on the variable column 6, and the lower end of the variable spring 7 is in compression contact with the upper end of the sleeve 8.A cylindrical slider 5 and an infusion tube 32 are fixedly mounted on the upper and lower ends of the variable column 6, respectively. The infusion tube 32 is movably inserted into the cavity of the sleeve 8. The outlet end of the infusion tube 32 is interconnected with the mixing tank 33 and is slidably inserted into a vertical slot on the side wall of the mixing tank 33. A flow-blocking plate 34 is fixedly mounted on the outlet end of the infusion tube 32. The flow-blocking plate 34 is located inside the cavity of the mixing tank 33 and is in close contact with the inner wall of the mixing tank 33 to facilitate the mixing process. The vertical slot on the side wall of the compound tank 33 is closed; the compound cylinder 13 is fixedly installed on the device frame assembly 9 below the sleeve 8, and a cylindrical piston 29 is inserted and moved vertically inside the compound cylinder 13. The upper end of the cylindrical piston 29 is fixedly connected to the lower inlet end of the infusion tube 32. A flow-blocking ball B35 is installed in the conical hole at the upper end of the cylindrical piston 29. A piston compression spring 28 is installed in the cylindrical cavity of the cylindrical piston 29. A ball cover 26 and a flow-blocking ball A2 are fixedly installed inside the bottom end of the compound cylinder 13. 7. Inside the spherical cover 26, the flow-blocking ball A27 seals the inlet of the agent cylinder 13. The upper and lower ends of the piston spring 28 are in compression contact with the cylindrical piston 29 and the spherical cover 26, respectively. A fixed suction tube 25 is connected to each other at the bottom of the agent cylinder 13. The suction tube 25 is inserted into the storage tank 14. Three stop wedges 3 are evenly distributed along the circumferential direction and are installed on the device frame assembly 9. A multi-tooth toothed bushing 4 is rotatably fitted on the cylindrical slider 5. Three vertical grooves are evenly distributed along the circumference on the outer wall of the multi-toothed toothed slider 2. The multi-toothed toothed slider 2 is mounted on the upper part of the multi-toothed toothed bushing 4 by the sliding engagement of three stop wedges 3 with the three vertical grooves on the multi-toothed toothed slider 2. The stop wedges 3 and the teeth of the multi-toothed toothed bushing 4 are in an insert-contact circumferential locking engagement. A variable adjustment button 1 is installed on the upper part of the multi-toothed toothed slider 2.

[0016] During the mixing operation, the rotary motor 23 drives the bevel gears A17 and B21 to rotate in opposite directions simultaneously via the motor shaft 24 and the bevel gear C22. When the double-end toothed sleeve 19 meshes with the lower end toothed bushing 18, the spiral shaft 16 rotates under the rotational power of the bevel gear A17. The sliding frame 15 moves upward on the spiral shaft 16, causing the storage tank 14 to move upward to the liquid outlet of the cylindrical piston 29 and nest with the infusion tube 32. As it continues to move upward, the cylindrical piston 29 presses downward, compressing the piston spring 28. The cylindrical piston 29 pushes the liquid in the cylinder 13 upward, and the pressurized liquid pushes open the flow-blocking ball B35. The liquid solution enters the mixing tank 33 through the infusion tube 32, completing a quantitative infusion operation into the mixing tank 33. When the upward-moving sliding frame 15 presses the reversing spring 12 on the upper side, when the reversing spring 12 reaches its pressing limit, the downward reaction force of the reversing spring 12 presses the sliding frame 15, the cylindrical stop slider 11, and the spiral shaft 16 downward together. At this time, the locking steel ball 30, under the pressing action of the locking spring 31, is positioned and locked into the annular groove on the upper side of the cylindrical stop slider 11. Simultaneously, the double-end toothed sleeve 19 disengages from the lower end toothed bushing 18 and enters the toothed engagement state with the upper end toothed bushing 20. Driven by rotation, the spiral shaft 16 rotates in the opposite direction. The sliding frame 15 drives the storage tank 14 to move downward on the spiral shaft 16. The piston spring 28 pushes the cylindrical piston 29 upward, causing a negative pressure to be generated in the cylinder 13. The flow-blocking ball A27 is sucked up, the liquid outlet of the storage tank 14 opens, and the liquid in the storage tank 14 is sucked into the cylinder 13, completing one quantitative supply operation into the cylinder 13. At the same time, the flow-blocking ball B35 is sucked downward due to the negative pressure in the cylinder 13, sealing the liquid outlet of the cylindrical piston 29. The sliding frame 15, which continues to move downward, squeezes the reversing spring 12 on the lower side. When the reversing spring 12 reaches its squeezing limit, the upward reaction force of the reversing spring 12... The sliding frame 15, the cylindrical stop slider 11, and the spiral shaft 16 are pressed upward together. At this time, the locking steel ball 30 is positioned and locked into the annular groove on the lower side of the cylindrical stop slider 11 under the pressure of the locking spring 31. Simultaneously, the double-end toothed sleeve 19 disengages from the upper end toothed bushing 20 and enters the toothed engagement state with the lower end toothed bushing 18. Driven by the rotational power of the bevel gear A17, the spiral shaft 16 rotates in the forward direction. The sliding frame 15 drives the storage tank 14 to move upward on the spiral shaft 16. This process is repeated continuously to carry out the operation. The two liquid composting agent raw materials in the two storage tanks 14 are mixed in the mixing tank 33 in different proportions.

[0017] When adjusting the mixing ratio of the two raw materials, pressing the variable adjustment button 1 causes the multi-toothed toothed slider 2 to move downwards along the stop wedge 3. With the toothed wall of the multi-toothed toothed slider 2 in contact with the toothed wall of the multi-toothed toothed bushing 4, the multi-toothed toothed bushing 4 drives the cylindrical slider 5 and simultaneously causes the variable column 6 to move downwards, generating a rotational torque. The pressure of the variable spring 7 increases. When the tooth tip of the multi-toothed toothed bushing 4 is lower than the stop wedge 3, the multi-toothed toothed bushing 4 breaks free from the rotational constraint of the stop wedge 3, and the multi-toothed toothed bushing... The toothed wall of sleeve 4 and the toothed wall of multi-toothed clutch slider 2 slide relative to each other until the stop wedge 3 is engaged again in the teeth of multi-toothed clutch bushing 4 to form a new rotational constraint. This fixes the position of variable column 6 fixed on multi-toothed clutch slider 2 and changes the height of infusion tube 32 fixed on variable column 6. That is, the critical contact height between cylindrical piston 29 and infusion tube 32 changes, the compression degree of piston spring 28 changes, and the amount of liquid discharged from the liquid cylinder 13 changes, thus completing the liquid variable mixing operation.
