Description

Technical Field

Organic fertilizer is processed from biomass, animal and plant waste, and plant residues. It is rich in a large number of beneficial substances. It can not only provide comprehensive nutrition for the growth of crops, but also has a long fertilizer effect. It can also increase and renew organic matter in the soil, promote microbial reproduction, and improve the physical and chemical properties of the soil. For the granulation of mixed fertilizers, a granulator is usually used in conjunction with a spiral extruder to extrude the fertilizer, and a cutting device is used during extrusion to complete the granulation, and a drying component is used to complete stable molding.

[0003] The prior art discloses a granulation and molding device for organic fertilizer, and the application publication number is CN116173830B. The application completes continuous and intermittent cutting and molding of organic fertilizer by rapidly reciprocating the cutting knife laterally, and cooperates with the stopper on the cutting knife to collide with the fixed block on the discharge plate, and cooperates with the elastic reset mechanism at the bottom of the discharge plate to make the discharge plate maintain lateral impact vibration, so that the granular organic fertilizer falling on the discharge plate produces lateral relative displacement on the discharge plate, so as to avoid the granular organic fertilizer with a certain viscosity from falling and adhering to the discharge plate.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] (1) In order to monitor the change of density of granular organic fertilizer on the oblique support, a reset spring and a vertical tooth plate are arranged under the oblique support. The weight of the organic fertilizer on the oblique support is different, and the distance moved by the vertical tooth plate is different, so that the change of the weight of the organic fertilizer can be converted into the change of the moving distance of the vertical tooth plate;

[0016] (2) The driving gear is meshed with the vertical toothed plate, and the vertical movement of the vertical toothed plate can be converted into the circular movement of the driving gear. A driven gear is provided, and the driven gear is meshed with the driving gear, so that the shaft rotates counterclockwise when the vertical toothed plate moves downward, thereby preventing the vertical toothed plate from failing to drive the horizontal toothed plate to move during the downward movement;

[0017] (3) The double-sided gear ring is rotatably arranged on the rotating shaft, and the inner wall of the double-sided gear ring is also provided with teeth, and a spring plate and a limiting arc plate are arranged on the rotating shaft. The spring plate can make the limiting arc plate clamped into the teeth of the inner wall of the double-sided gear ring, so that when the rotating shaft rotates counterclockwise, the limiting arc plate can drive the double-sided gear ring to rotate counterclockwise, and when the rotating shaft rotates clockwise, the teeth of the inner wall of the double-sided gear ring squeeze the spring plate through the limiting arc plate, and the limiting arc plate no longer clamps into the teeth of the inner wall of the double-sided gear ring, thereby failing to drive the double-sided gear ring to rotate, that is, when the vertical tooth plate moves downward, it can drive the double-sided gear ring to rotate, and when the vertical tooth plate moves upward, it cannot drive the double-sided gear ring to rotate, thereby achieving the purpose of sequentially monitoring the weight of the granular organic fertilizer;

[0018] (4) The protrusion on the sliding block is arranged at one end of the sliding block, the protrusion on the sliding block is slightly shorter, and cooperates with the position determination component and the electrostrictive grafted elastomer, so that only when the end of the sliding block touches the upper part of the rotating plate, the protrusion on the sliding block will move to the position of the infrared sensor, that is, trigger the infrared sensor, so that the single chip microcomputer controls the electrostrictive grafted elastomer to be powered off and contracted, and at this time the upper part of the rotating plate is closest to the support plate, thereby achieving the effect of recovering the electrostrictive grafted elastomer when the sliding block touches the upper part of the rotating plate, thereby providing a possibility for increasing the resistance value of the sliding rheostat, and when the density of the granular organic fertilizer is relatively small, the protrusion on the sliding block cannot move to the position of the infrared sensor, so that the infrared sensor transmits the signal to the single chip microcomputer, so that the electrostrictive grafted elastomer is powered on and extended, which provides a possibility for reducing the resistance value of the sliding rheostat;

[0019] (5) The rotating plate is fixed on the rotating rod, and the rotating rod is rotated on the supporting column, so as to achieve the effect of reverse movement of the upper and lower ends of the rotating plate, and the adjustment rod is driven to move by the passive slider and the active slider, so as to achieve the purpose of adjusting the resistance value on the sliding rheostat, and then adjust the rotation speed of the motor;

[0020] (6) When the density of the granular organic fertilizer is small, the weight of the granular organic fertilizer is small, the distance that the vertical tooth plate moves downward is short, and the protrusion on the sliding block cannot move to the position of the infrared sensor. The electrostrictive grafted elastomer is energized and stretched, so that the lower end of the rotating plate is away from the supporting plate, the resistance of the sliding rheostat decreases, the motor speed increases, and the cutting component cooperates, so that the weight of the granular organic fertilizer to be cut again increases, the downward distance of the vertical tooth plate is lengthened, and the movement distance of the sliding block is lengthened. If the protrusion on the sliding block still cannot reach the position of the infrared sensor, the resistance of the sliding rheostat remains unchanged until the protrusion on the sliding block just reaches the position of the infrared sensor, the electrostrictive grafted elastomer is powered off and shrinks, and the sliding block is The resistance of the rheostat remains unchanged, the weight of the granular organic fertilizer continues to increase, the distance moved by the sliding block continues to increase, and the resistance of the sliding rheostat continues to increase, so that the resistance of the sliding rheostat is in a balanced state, the rotation speed of the motor is in a balanced state, and the density of the granular organic fertilizer is in the standard requirement. If the density of the granular organic fertilizer is too large, the distance moved by the sliding block is too large, so that the resistance of the sliding rheostat is greater than the resistance in the balanced state, and the rotation speed of the motor decreases until the density of the granular organic fertilizer is lower than the standard requirement, so that the electrostrictive grafted elastomer is energized and stretched again, and the density of the granular organic fertilizer reaches the standard state again, thereby achieving the purpose of automatic monitoring and adjustment of the density of the granular organic fertilizer.

[0042] like Figure 8-Figure 9 As shown, the extrusion assembly 6 includes a fixed platform 41, an extrusion barrel 42, a fixed cross plate 43, a motor 44 and an auger 45.

[0043] like Fig.10 As shown, the cutting assembly 7 includes a travel switch 46, a hydraulic pump 47 and a cutter 48. The travel switch 46 is fixed on the side plate 2, the hydraulic pump 47 is fixed on the side plate 2, the cutter 48 is fixed on the output end of the hydraulic pump 47, the travel switch 46 is electrically connected to the hydraulic pump 47, and the hydraulic pump 47 is electrically connected to an external power supply.

[0044] When in use, the organic fertilizer raw material enters the extrusion barrel 42 through the feed port on the extrusion barrel 42, the motor 44 is turned on, the motor 44 drives the auger 45 to rotate, the auger 45 transports the organic fertilizer raw material to the tail end of the extrusion barrel 42, and the organic fertilizer raw material is extruded through the extrusion pipe at the tail end of the extrusion barrel 42, the hydraulic pump 47 is turned on, and the output end of the hydraulic pump 47 drives the cutter 48 to move. After the cutter 48 moves to a certain position, the travel switch 46 controls the output end of the hydraulic pump 47 to move in the opposite direction. After the output end of the hydraulic pump 47 moves to the corresponding position, the travel switch 46 continues to control the hydraulic pump 47 to repeat the above movement, and the cutter 48 cuts the extruded organic fertilizer raw material into granules. The granular organic fertilizer falls onto the oblique support 11, and under the gravity of the organic fertilizer, The oblique support 11 moves downward, the oblique support 11 squeezes the reset spring 10, the oblique support 11 drives the vertical tooth plate 12 to move downward, the vertical tooth plate 12 drives the active gear 19 to rotate clockwise, the active gear 19 drives the driven gear 15 to rotate counterclockwise, the driven gear 15 drives the rotating shaft 14 to rotate counterclockwise, under the action of the spring plate 18, the limiting arc plate 17 clamps the teeth on the inner wall of the double-sided gear ring 16, the rotating shaft 14 rotates counterclockwise, driving the spring plate 18 and the limiting arc plate 17 to rotate counterclockwise, the limiting arc plate 17 drives the double-sided gear ring 16 to rotate counterclockwise, the double-sided gear ring 16 drives the transverse tooth plate 23 to move in the direction of the motion conversion adjustment component 27, the transverse tooth plate 23 compresses the pull-back spring 22, and the transverse tooth plate 23 drives the sliding block 25 to move The dynamic conversion adjustment component 27 moves in the direction of the dynamic conversion adjustment component 27. If the density of the granular organic fertilizer is small, the vertical tooth plate 12 moves downwardly for a small distance, the position of the protrusion on the sliding block 25 is not at the position of the infrared sensor 30, and the infrared sensor 30 cannot sense the protrusion on the sliding block 25. The infrared sensor 30 sends a signal to the single-chip microcomputer 29, and the single-chip microcomputer 29 controls the electrostrictive grafted elastomer 24 to be in an energized extension state. The electrostrictive grafted elastomer 24 pushes the bottom of the rotating plate 33 to be at the farthest point on one side of the support column 31. The passive slider 38 is at the farthest point from the electrostrictive grafted elastomer 24 through the limiting rod 34. The passive slider 38 drives the active slider 37 to be at the farthest point from the electrostrictive grafted elastomer 24, and the active slider 37 drives the adjustment rod 39 to be at the farthest point from the electrostrictive grafted elastomer 24. At the farthest point of the electrostrictive grafted elastomer 24, the adjusting rod 39 adjusts the resistance value on the sliding rheostat 40 to the minimum position. At this time, the rotation speed of the motor 44 is at the maximum, and the organic fertilizer in the extrusion barrel 42 is squeezed to the extrusion pipe on the extrusion barrel 42 at the maximum speed. The pressure of the inner wall of the end of the extrusion barrel 42 on the organic fertilizer in the extrusion barrel 42 increases, thereby increasing the density of the organic fertilizer in the extrusion barrel 42. When the organic fertilizer particles on the oblique support 11 slide down, the reset spring 10 rebounds, driving the oblique support 11 to move upward, and is transmitted through the vertical tooth plate 12 and the driving gear 19, so that the driven gear 15 rotates clockwise, and the driven gear 15 drives the rotating shaft 14 to rotate clockwise, and the rotating shaft 14 drives the limiting arc plate 17 and the spring plate 18 to rotate clockwise.The limiting arc plate 17 no longer drives the double-sided gear ring 16 to rotate, and the double-sided gear ring 16 loses the restriction on the transverse tooth plate 23. Under the action of the return spring 22, the transverse tooth plate 23 is retracted, driving the sliding block 25 to be retracted, and the transverse tooth plate 23 returns to its original position. After the cutter 48 cuts the organic fertilizer again, the weight of the organic fertilizer particles falling into the oblique support 11 increases, and the distance the vertical tooth plate 12 moves downward increases. After the transmission through the active gear 19, the driven gear 15, the rotating shaft 14 and the double-sided gear ring 16, the distance the transverse tooth plate 23 moves toward the motion conversion adjustment component 27 increases, and the transverse tooth plate 23 pushes the sliding block 25 to move toward the motion conversion adjustment component 27. When the position of the raised end of the sliding block 25 exceeds the infrared sensor 30, the infrared sensor 30 senses the position of the raised end of the sliding block 25 and sends a signal to the single chip microcomputer 29, so that the single chip microcomputer 29 controls the electrostrictive grafted elastic body 24 to be in a power-off and contracted state, and the electrostrictive grafted elastic body 24 loses the limiting effect on the lower end of the rotating plate 33. The sliding block 25 pushes the upper part of the rotating plate 33 to rotate clockwise, and the rotating plate 33 drives the limiting rod 34 to rotate clockwise. The limiting rod 34 drives the passive sliding block 38 to move in the direction close to the support plate 20, and the passive sliding block 38 drives the active sliding block 37 to move in the direction close to the support plate 20, and the active sliding block 37 drives the adjustment The rod 39 slides in the direction close to the support plate 20, and the adjustment rod 39 adjusts the resistance of the sliding rheostat 40 to increase, and the rotation speed of the motor 44 decreases, but it is not yet in a balanced state, that is, the density of the organic fertilizer particles is still low, but compared with the granular organic fertilizer cut for the first time, the density is increased, the weight of the granular organic fertilizer continues to increase, the resistance of the sliding rheostat 40 continues to increase, and the rotation speed of the motor 44 continues to decrease until the density of the granular organic fertilizer meets the requirement, and the rotation speed of the motor 44 is in a balanced state. If the density of the granular organic fertilizer is large, the sliding block 25 pushes the rotating plate 33 to rotate farther in the clockwise direction, and the limit rod 34 and the passive sliding After the block 38, the active slider 37 and the adjustment rod 39 are transmitted, the resistance value of the sliding rheostat 40 is larger, so that the rotation speed of the motor 44 is lower than the rotation speed in the equilibrium state, the extrusion force on the organic fertilizer in the extrusion barrel 42 becomes smaller, and the density of the granular organic fertilizer decreases. The above procedures are repeated until the density of the granular organic fertilizer is lower than the standard requirement. When the protrusion on the sliding block 25 cannot reach the position of the infrared sensor 30, the infrared sensor 30 transmits a signal to the single-chip microcomputer 29, and the single-chip microcomputer 29 makes the electrostrictive grafted elastomer 24 energized and extended, so that the resistance value of the sliding rheostat 40 becomes the smallest, and the cutting of organic fertilizer is repeated until the density of the organic fertilizer reaches the standard requirement.
