[0034] In this embodiment, a sleeve 26 is fixedly connected to the interior of the transfer bucket 6, and a spiral blade 27 is rotatably connected to the interior of the sleeve 26. A square groove is provided at the bottom end of the sleeve 26, and a discharge plate 28 is fixedly connected to the top end of the sleeve 26. The discharge plate 28 extends to the interior of the discharge hopper 4. By cyclically rotating the spiral blade 27, the block fertilizer inside the transfer bucket 6 is circulated and raised, and finally, through the design of the discharge plate 28, it is re-transmitted to the interior of the discharge hopper 4, eliminating the need for manual sorting of uncrushed fertilizers from a pile of crushed fertilizers, thereby greatly saving labor.

[0035] In this embodiment, the outside of the lower hopper 4 is symmetrically rotatably connected to a synchronous wheel 29, the outside of the synchronous wheel 29 is meshed with a synchronous belt 30, the inside of the synchronous wheel 29 is fixedly connected to a first plug shaft, the outside of the first plug shaft is fixedly connected to a third gear, the outside of the third gear is meshed with a fourth gear, the inside of the fourth gear is fixedly connected to a second plug shaft, the outsides of the first plug shaft and the second plug shaft are fixedly connected to a cylinder 31, the outside of the cylinder 31 is fixedly connected to crushing teeth 32, and multiple groups of crushing teeth 32 are distributed at equal intervals. By placing a motor on the outside of the lower hopper 4 and connecting its output end to the first plug shaft, one group of synchronous wheels 29 is rotated, and then meshed with the synchronous belt 30, so that the third gear and the fourth gear are meshed with each other, and then multiple groups of cylinders 31 are rotated in the same direction, and then the crushing teeth 32 are driven to rotate, and the friction between them will directly crush the fertilizer.

[0036] In this embodiment, a first guide plate 33 is fixedly connected to the inner wall of the lower hopper 4 and located below the cylinder 31, and a second guide plate 34 is fixedly connected to the inner wall of the receiving bucket 3 and located above the square frame 9. The first guide plate 33 extends to the top of the second guide plate 34. The first guide plate 33 and the second guide plate 34 are both designed with an inclined structure. The crushed fertilizer is affected by gravity and guided by the first guide plate 33 and the second guide plate 34, so that it slides directly into the interior of the filter frame 8.

[0037] In this embodiment, a fixing ring 35 is fixedly connected to the top of the filter frame 8, and a plug rod 36 is slidably connected inside the fixing ring 35. A spring 37 is sleeved on the outside of the plug rod 36 and located inside the fixing ring 35. A guide tube 38 is fixedly connected to the outside of the fixing ring 35 and located inside the filter frame 8. A cylindrical hole 39 is symmetrically opened at the bottom end of the guide tube 38, and a card ball 40 is slidably connected inside the cylindrical hole 39. A card groove is opened at a position corresponding to the card ball 40 inside the filter screen 23. The bottom end of the plug rod 36 is fixedly connected to an extrusion block 41, and an elastic block 42 is symmetrically slidably connected to the outside of the extrusion block 41. The elastic block 42 is adapted to be used with the card ball 40. When the filter screen 23 is long, During time screening, when the gaps between the filters 23 are blocked, causing the working efficiency of the filters 23 to be greatly reduced, the rod 36 can be pulled out upward, and then the rod 36 will extend upward inside the guide tube 38 and compress the spring 37. At the same time, when the rod 36 rises, it drives the extrusion block 41 to rise synchronously, and then the elastic block 42 rises synchronously to release the extrusion of the card ball 40. When the card ball 40 loses its driving force, it will completely retract into the inside of the barrel hole 39 and disengage from the inside of the card slot, so that the connection between the filter 23 and the filter frame 8 is lost. The filter 23 loses its supporting force and will directly slide out of the filter frame 8, which is convenient for cleaning the filter 23 and extends its service life.

[0038] In this embodiment, the bottom end of the inner side of the receiving bucket 3 is rotatably connected to the vertical shaft 43, and the outer part of the vertical shaft 43 is provided with a stirring blade 44. The outer part of the vertical shaft 43 is fixedly connected to multiple groups of mounting seats, and the inner parts of the multiple groups of mounting seats are all rotatably connected to connecting rods 45, and the multiple groups of connecting rods 45 are rotatably connected to the pulling rods 46. The top of the vertical shaft 43 is symmetrically rotatably connected to the telescopic cylinder, and the output end of the telescopic cylinder is rotatably connected to a group of connecting rods 45. As the filter 23 is screened, the fertilizer that meets the requirements will directly fall into the interior of the receiving bucket 3. By connecting the motor to the bottom of the vertical shaft 43, the vertical shaft 43 is then rotated, driving the stirring blades 44 to rotate, and the fertilizer is stirred to prevent agglomeration due to moisture. Subsequently, the telescopic cylinder is driven to drive one group of connecting rods 45 to rise and fall, and the lifting rod 46 moves synchronously, so that the multiple groups of connecting rods 45 can perform cyclic rising and falling movements, turn the fertilizer, and further improve the stirring effect.

[0039] Implementation plan: By placing the support foot 1 at a specified position and supporting the frame 2, the frame 2 is placed in a vertical state, and then the receiving bucket 3 is inserted into the interior of the frame 2, so that the receiving bucket 3 is suspended as a whole, driving the lower hopper 4 to be at the top of the receiving bucket 3, and by squeezing the block fertilizer with the protective door 5, and then the protective door 5 is tilted toward the inside of the through groove to prevent the protective door 5 from blocking the operator's test and causing injury, by placing the motor outside the lower hopper 4, and connecting its output end to the first plug shaft, one set of synchronous wheels 29 is rotated, and then meshed with the synchronous belt 30, so that the third gear and the fourth gear are meshed with each other, and then multiple sets of cylinders 31 are rotated in the same direction, and then the crushing teeth are driven. 32 rotates and rubs against each other, which will directly crush the fertilizer. At the same time, when the lower hopper 4 crushes the fertilizer, a large amount of dust will be generated, and the dust will be discharged from the body through the exhaust fan 401. The crushed fertilizer is affected by gravity and guided by the first guide plate 33 and the second guide plate 34, so that it slides directly into the inside of the filter frame 8, and the crushed fertilizer is screened by the filter frame 8. By connecting the turntable 19 to the external power supply, the turntable 19 is circulated and rotated on the outside of the extension rod 15, and the driven rod 20 is driven to rotate at the same time. Then the positioning column 21 squeezes the receiving groove 17 to realize the swinging rod 16 to swing. Then the bottom end of the swinging rod 16 is the force point and swings. At the same time, the receiving groove 17 The first gear 12 is driven by the limit shaft 18 to slide, and the limit shaft 18 engages with the first tooth plate 13, and then drives the first gear 12 to rotate, and engages with the tooth groove in the second tooth plate 14, and generates a thrust on the second tooth plate 14, so that the second tooth plate 14 slides back and forth at the top of the square frame 9, and the pull rod 22 moves synchronously, and at the same time drives the filter frame 8 to move repeatedly, and the fertilizer is filtered through the filter screen 23. At the same time, when the filter frame 8 slides, it can accelerate its screening, and the uncrushed fertilizer will enter the first extension sleeve 24 through the shaking of the filter frame 8, and then enter the interior of the second extension sleeve 25, and appear in the interior of the transfer bucket 6, and the spiral blade 27 is circulated. The block fertilizer in the transfer bucket 6 is circulated and raised, and finally transferred to the lower hopper 4 through the design of the lower plate 28, eliminating the need to manually pick out the uncrushed fertilizer from a pile of crushed fertilizer, which greatly saves labor. With the screening of the filter 23, the fertilizer that meets the requirements will directly fall into the receiving bucket 3. The motor is connected to the bottom of the vertical shaft 43, and then the vertical shaft 43 is rotated to drive the stirring blade 44 to rotate, so as to stir the fertilizer to prevent agglomeration due to moisture. Then the telescopic cylinder is driven to drive one group of connecting rods 45 to rise and fall, and the lifting rod 46 moves synchronously, so as to realize the cyclic rising and falling movement of multiple groups of connecting rods 45 to turn the fertilizer.To further improve the stirring effect, when the filter 23 is screened for a long time and the gaps between the filter 23 are blocked, resulting in a significant reduction in the working efficiency of the filter 23, the rod 36 is pulled out upward, and then the rod 36 extends upward inside the guide tube 38 and compresses the spring 37. At the same time, when the rod 36 rises, it drives the extrusion block 41 to rise synchronously, and then the elastic block 42 rises synchronously to release the extrusion of the card ball 40. When the card ball 40 loses its driving force, it will completely retract into the inside of the cylinder hole 39 and detach from the inside of the card slot, so that the connection between the filter 23 and the filter frame 8 is lost. The filter 23 loses its supporting force and will directly slide out of the filter frame 8, which is convenient for cleaning the filter 23 and extends its service life.
