On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0025] The organic fertilizer crushing and impurity removal equipment of the embodiment of the present application is described below with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, the crushing and impurity removal equipment for organic fertilizer in the embodiment of the present application may include a crushing drum 1, a screening drum 2, a first crushing component 3, two locking components 4, a second crushing component 5, multiple impurity removal components 6, a first transmission component 7 and a second transmission component 8.

[0027] The crushing drum 1 is suspended by two first support plates 10 , and a feeding hopper 11 is connected to the top of the crushing drum 1 , the first crushing assembly 3 is rotatably arranged inside the feeding hopper 11 , and a discharge port is arranged at the bottom of the crushing drum 1 .

[0028] It should be noted that the crushing drum 1 described in this embodiment is a hollow cylindrical structure with one end open and the other end closed. Guide plates are respectively provided on the two opposite inner walls of the feeding hopper 11. The two guide plates are inclined to guide the fertilizer to the top of the first crushing component 3. The screening drum 2 is a cylindrical structure with both ends closed, and a plurality of sieve holes are evenly distributed on the curved surface of the screening drum 2 to screen the crushed fertilizer.

[0029] Furthermore, the first crushing component 3 can perform the first crushing on the fertilizer to break the block fertilizer into small pieces. After the small pieces of fertilizer enter the screening drum 2, they can be crushed again, and at the same time they can be screened and impurities removed. The discharge port is located directly below the feeding hopper 11, which is used to discharge the crushed and screened fertilizer.

[0030] In an embodiment of the present application, a plurality of partition plates 9 are provided in an inner ring shape of the screening drum 2. The partition plates 9 can separate a plurality of spaces inside the screening drum 2. During the rotation of the screening drum 2, the partition plates 9 can make the fertilizer roll along with the screening drum 2, and finally make the fertilizer fall from a height to be fully crushed.

[0031] The screening drum 2 is rotatably arranged inside the crushing drum 1, and a feed port is provided on the screening drum 2, and two sealing mesh plates 12 are provided on the feed port. A box body 13 is provided inside the screening drum 2, and a locking assembly 4 is arranged inside the box body 13, and the two locking assemblies 4 are respectively connected to the corresponding sealing mesh plates 12.

[0032] It should be noted that when fertilizer is fed into the screening drum 2, the feed port corresponds to the position of the hopper 11, and the two sealing mesh plates 12 can block the feed port to prevent the fertilizer from falling from the feed port when the screening drum 2 rotates.

[0033] Furthermore, the locking assembly 4 can open and close the sealing mesh plate 12 , thereby facilitating feeding of materials into the interior of the screening drum 2 .

[0034] The second crushing assembly 5 is rotatably arranged inside the screening drum 2. A second support plate 14 is provided on one side of the crushing drum 1. A connecting ring 15 is provided on the side of the screening drum 2 adjacent to the second support plate 14. The first transmission assembly 7 is arranged on the second support plate 14, and the first transmission assembly 7 is connected to the connecting ring 15.

[0035] It should be noted that the second crushing assembly 5 described in this embodiment can crush the fertilizer multiple times, thereby improving the uniformity of the fertilizer crushing.

[0036] Furthermore, the first transmission assembly 7 can drive the connecting ring 15 and the screening drum 2 to rotate slowly, thereby achieving simultaneous screening and crushing.

[0037] A plurality of impurity removal components 6 are arranged in a circular array around the second crushing component 5, and one end of the impurity removal component 6 extends to the outside of the screening drum 2. The second transmission component 8 is arranged on the second support plate 14, and the second transmission component 8 is connected to the plurality of impurity removal components 6 respectively.

[0038] It should be noted that the impurity removal component 6 described in this embodiment can remove longer impurities in the fertilizer to ensure the quality of the fertilizer. At the same time, when the screening drum 2 drives the impurity removal component 6 to rotate, with the cooperation of the second transmission component 8, it can also drive the impurity removal component 6 to rotate, so as to wrap the impurities in the fertilizer around the impurity removal component 6, thereby achieving the purpose of rapid impurity removal.

[0039] In one embodiment of the present application, Figure 2 As shown, the first crushing assembly 3 may include two first crushing shafts 30 and two crushing rollers 31, wherein the two first crushing shafts 30 are rotatably arranged inside the feeding hopper 11, the two crushing rollers 31 are respectively arranged on the corresponding first crushing shafts 30, and the outer wall of the crushing roller 31 is evenly distributed with multiple first crushing knives.

[0040] It should be noted that the two first crushing shafts 30 described in this embodiment are connected to an external driving mechanism, and the driving structure can drive the two first crushing shafts 30 to rotate in opposite directions. The first crushing knife is arranged parallel to the axial direction of the crushing roller 31. By driving the two crushing rollers 31 to rotate in opposite directions, large pieces of fertilizer can be squeezed and crushed.

[0041] Furthermore, if Figure 4 and Figure 5 As shown, the locking assembly 4 may include an arcuate tooth plate 40, a drive shaft 41 and a first gear 42, wherein the arcuate tooth plate 40 is arranged on the arcuate concave surface of the sealing mesh plate 12, the drive shaft 41 is rotatably arranged inside the box body 13, the first gear 42 is arranged on the drive shaft 41, and the first gear 42 is meshedly connected with the arcuate tooth plate 40.

[0042] In an embodiment of the present application, the drive shaft 41 is connected to the motor, and the motor is installed inside the box body 13. The motor can drive the drive shaft 41 to rotate, and through the cooperation of the first gear 42 and the arc-shaped tooth plate 40, drive the sealing mesh plate 12 to rotate a certain angle to achieve control of the two sealing mesh plates 12.

[0043] In one embodiment of the present application, Figure 5 As shown, two slide grooves 20 are provided near the feed port of the screening drum 2 , and the two sealing mesh plates 12 are slidably connected to the corresponding slide grooves 20 .

[0044] In an embodiment of the present application, when the feed port is in an open state, the two sealing mesh plates 12 are respectively hidden in the corresponding chutes 20. At this time, the feed port is located directly below the feeding hopper 11, so that it is convenient to feed fertilizer into the interior of the screening drum 2.

[0045] In one embodiment of the present application, Figure 2As shown, the second crushing assembly 5 may include a second crushing shaft 50 and a plurality of second crushing knives 51, wherein one end of the second crushing shaft 50 is rotatably connected to the inner wall of the crushing barrel 1, and the other end of the second crushing shaft 50 passes through the crushing barrel 1 and is rotatably connected to the second support plate 14, and the plurality of second crushing knives 51 are evenly distributed on the second crushing shaft 50.

[0046] It should be noted that the crushing shaft 50 described in this embodiment is coaxially arranged with the crushing barrel 1, and the crushing shaft 50 is connected to a motor, and the crushing shaft 50 can be driven to rotate by the motor, thereby driving the multiple second crushing knives 51 to rotate, so as to achieve the re-crushing of the fertilizer.

[0047] Furthermore, if Figure 3 As shown, the first transmission assembly 7 may include two second gears 70, a transmission shaft 71 and a first gear ring 72, wherein the transmission shaft 71 is rotatably arranged on a side of the second support plate 14 adjacent to the screening drum 2, the two second gears 70 are respectively arranged on the transmission shaft 71 and the second crushing shaft 50, and the two second gears 70 are meshedly connected, and the first gear ring 72 is arranged on the inner wall of the connecting ring 15, and the first gear ring 72 is meshedly connected with the second gear 70 on the transmission shaft 71.

[0048] It should be noted that the diameter of the second gear 70 on the transmission shaft 71 is greater than the diameter of the second gear 70 on the second crushing shaft 50. By utilizing the principle that the small gear drives the large gear to reduce speed, the screening drum 2 can be driven to rotate slowly.

[0049] In one embodiment of the present application, Figure 2 As shown, the impurity removal component 6 may include a rotating shaft 60 and a plurality of thorn rods 61 , wherein one end of the rotating shaft 60 is rotatably connected to the inner wall of the screening drum 2 , and the other end of the rotating shaft 60 passes through the screening drum 2 , and the plurality of thorn rods 61 are evenly distributed on the rotating shaft 60 .

[0050] It should be noted that one end of the rotating shaft 60 described in this embodiment extends to the outside of the screening drum 2, and multiple rotating shafts 60 are arranged in a circular array around the second crushing shaft 50, and multiple needles are evenly distributed on the piercing rod 61, which can better hook longer impurities.

[0051] Furthermore, if Figure 3 As shown, the second transmission assembly 8 may include a second gear ring 80 and a plurality of third gears 81 , wherein the second gear ring 80 is disposed on the second support plate 14 , the plurality of third gears 81 are respectively disposed on corresponding rotating shafts 60 , and the plurality of third gears 81 are respectively meshed and connected with the second gear ring 80 .

[0052] In the embodiment of the present application, when the screening drum 2 rotates, it can drive the impurity removal component 6 and the third gear 81 to rotate. At the same time, it is restricted by the second gear ring 80, so that the third gear 81 can also rotate on its own, thereby driving the impurity removal component 6 to rotate on its own. During the rotation of the impurity removal component 6, longer impurities can be wound around the rotating shaft 60 to achieve the purpose of impurity removal.

[0053] Specifically, during the process of crushing and removing impurities from the fertilizer, relevant personnel control the feed port of the screening drum 2 to be in an open state, and adjust the position of the feed port so that the feed port is located directly below the feeding hopper 11.

[0054] Then the first crushing component 3 can be controlled to start, and the relevant personnel will feed the block-shaped organic fertilizer into the interior of the feeding hopper 11, and after being crushed by the first crushing component 3, it enters the interior of the screening drum 2. When the fertilizer inside the screening drum 2 accumulates to a certain amount (greater than one-third of the volume of the screening drum 2 and less than one-half of the volume of the screening drum 2 is optimal), the feeding into the feeding hopper 11 can be stopped, and the driving shaft 41 can be controlled to start. The driving shaft 41 drives the first gear 42 to rotate, and through the cooperation of the arc-shaped tooth plate 40, drives the two sealing mesh plates 12 to rotate toward each other at a certain angle, and finally makes the two sealing mesh plates 12 fit closely to block the feed port.

[0055] Subsequently, the relevant personnel can control the second crushing component 5 to start, and the fertilizer inside the screening drum 2 can be crushed again through the second crushing component 5. At the same time, when the second crushing shaft 50 rotates, with the cooperation of the first transmission component 7, the screening drum 2 can be driven to rotate slowly. When the screening drum 2 rotates, the partition plate 9 can not only divide the screening drum 2 into multiple small spaces to separate the fertilizers, but also prevent the fertilizer from sliding along the curved inner wall of the screening drum 2, so that the fertilizer can fall from a higher place of the screening drum 2, which is beneficial to disperse the fertilizer and also beneficial to fully crush the fertilizer again.

[0056] At the same time, because the third gear 81 is in meshing state with the second gear ring 80, and the second gear ring 80 is fixed, when the screening drum 2 drives the third gear 81 to rotate, the third gear 81 can rotate on its own, and drive the rotating shaft 60 and the thorn rod 61 to rotate on their own, so as to be able to fully contact the fertilizer, so as to wrap the longer impurities in the fertilizer around the thorn rod 61, thereby achieving the purpose and improving the quality of the fertilizer.

[0057] Furthermore, during the rotation of the screening drum 2, the fertilizer can also be screened, and the screened fertilizer will be discharged from the discharge port, thereby making the fertilizer more uniform.

[0058] In summary, the organic fertilizer crushing and impurity removal equipment of the embodiment of the present application adopts a one-time feeding method, which can achieve multiple crushing of organic fertilizers. The operation is simple and efficient, which improves the crushing effect of the fertilizer and removes impurities in the fertilizer during the crushing process, thereby ensuring the quality of the fertilizer.
