Description

Technical Field

[0001] This utility model relates to the field of feed grinding technology, and specifically discloses a fine grinding device for mulberry leaf feed. Background Technology

[0002] Mulberry leaf feed is an animal feed made primarily from mulberry leaves, widely used in animal husbandry, especially in sericulture and sheep farming. Mulberry leaves are rich in protein, vitamins, minerals, and antioxidants, making them a high-quality feed ingredient. The production of mulberry leaf feed typically involves drying and dehydrating the leaves. This process ensures the quality and shelf life of the feed. Drying effectively removes moisture from the mulberry leaves, preventing the growth of mold and bacteria, and extending the feed's shelf life. Dried mulberry leaf feed is more stable and less prone to spoilage.

[0003] For example, the utility model patent with authorization announcement number CN220195134U discloses a fine feed raw material crushing device, including a crushing device body and a screening device body. A crusher is installed inside the crushing device body, and a second rotating shaft is connected to the bottom of the crusher. A second motor is connected to the bottom of the second rotating shaft. A brush rod is installed in front of the second motor, and a filter screen is installed at the bottom of the brush rod. A feeding trough is installed below the filter screen, and the screening device body is installed above the feeding trough. A first motor is installed above the screening device body, and a feeding inlet is installed on the right side of the first motor. A mixer and a first gear are connected to the left side of the feeding inlet. A second gear and a first rotating shaft are installed to the left side of the first gear, and a brush mechanism and a screen are installed to the left side of the first rotating shaft. A support rod is installed at the bottom of the screen. This fine feed raw material crushing device, with the screening device body installed above the crushing device body, screens the feed, ensuring that the size of the feed falling is uniform, which is beneficial to improving crushing efficiency.

[0004] Currently, when mulberry leaves are processed into feed ingredients, they are first dehydrated and air-dried to make them brittle. This prevents the leaves and stems from sticking together and avoids the release of excessive juice during crushing. Most crushing methods use a single blade to cut the leaves into powder. However, due to the complexity of some feed production processes, blade crushing still results in some mulberry leaves forming large lumps. These lumps require secondary crushing during the later screening process, significantly increasing production time and reducing work efficiency. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a fine grinding device for mulberry leaf feed, so as to solve the problem that when using a single blade for grinding, due to the thinness of mulberry leaves, some mulberry leaf pieces will be large when the grinding volume is large.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fine grinding device for mulberry leaf feed, including a grinding mechanism, a driving mechanism is provided inside the grinding mechanism, and a dust removal mechanism is provided outside the grinding mechanism, with the dust removal mechanism symmetrically distributed along the grinding mechanism.

[0007] In detail, the crushing mechanism includes a cylinder with a feeding port through one side. An extension platform is provided at the end of the cylinder away from the feeding port. A support frame is provided above the extension platform. A cylinder is provided through the horizontal position of the support frame. A piston rod for driving is provided inside the cylinder. The piston rod ends of the two cylinders are provided with the same pressure block. The outer ring wall of the pressure block is slidably sleeved with the inner ring wall of the cylinder.

[0008] A support cylinder is provided at the bottom of the cylinder, and notches are opened at both ends of the support cylinder.

[0009] In detail, a grinding sleeve is provided at the lower end of the inner cavity of the cylinder, and a grinding table is provided through the inner cavity of the grinding sleeve. Several baffles are also distributed on the inner wall of the cylinder, and several crushing columns are distributed on the upper end of the outer ring wall of the grinding table. Several pointed protrusions are distributed on the surface of the crushing columns.

[0010] In detail, the surface of the cylinder is provided with several bearings, the inside of the bearings is provided with a shaft, the inner end of the shaft is provided with several sets of blades, the outer end of the shaft is provided with a motor, the inside of the motor is provided with a drive shaft, and the end of the drive shaft is fixedly connected to the outer end of the shaft by a coupling.

[0011] In detail, the drive mechanism includes a second bearing, a second shaft is provided through the inside of the second bearing, a linkage bevel gear is provided below the second shaft, and a centrifugal disc is also wrapped on the surface of the second shaft.

[0012] In detail, a bearing three is provided through the surface of the support cylinder, and a shaft three is provided through the interior of the bearing three. A drive bevel gear is provided at one end of the shaft three inside the support cylinder. The drive bevel gear and the linkage bevel gear are meshed with each other. A motor two is provided at the outer end of the shaft three. A rotating shaft two for driving is provided inside the motor two. The end of the rotating shaft two and the end of the shaft three are fixedly connected by a coupling.

[0013] In detail, the dust removal mechanism includes a positioning plate located above the notch. A dust suction hood is installed through the interior of the positioning plate. The dust suction hood has an inner cavity, and a mesh plate is fixedly embedded in the opening of the inner cavity. A connecting pipe is connected to the flange at the upper end of the interface of the dust suction hood.

[0014] In detail, a dust collection cylinder is also provided above the positioning plate. A grid is provided at the end of the dust collection cylinder away from the connecting pipe. An inner cylinder is provided inside the dust collection cylinder. A channel is provided through the inner cylinder. The channel is wider at the front and narrower at the back. An isolation net is embedded and fixed in the narrow opening. A motor is also provided inside the dust collection cylinder. A rotating shaft is provided inside the motor for driving. Several blades are fixed at the end of the rotating shaft.

[0015] The working principle and beneficial effects of this solution are as follows: 1. When mulberry leaves need to be crushed, dehydrated and dried mulberry leaves can be fed into the cylinder used for crushing through the feeding interface. Then, the mulberry leaves will fall above the grinding table. When the power of motor two is turned on, the rotating shaft two can be driven, thereby enabling the drive bevel gear to mesh and rotate, and causing shaft two to rotate. Thus, the grinding table can be rotated. Through the centrifugal effect of the grinding table, the mulberry leaves can be thrown to the edge and contact the crushing column. Through the impact contact between the tip protrusion and the mulberry leaves, and with the delay of the falling of the baffle column, the mulberry leaves can fully contact the tip protrusion, which can realize the operation of changing from large to small.

[0016] 2. As described in 1, in order to avoid missing large mulberry leaves that are not crushed, the power supply of motor one can be turned on, so that motor one can drive shaft one, thereby realizing the rotation of shaft one, which can drive the blade to rotate, and can crush the blades that cannot pass through the blade area normally. After being crushed from large to small, the blades will enter the gap between the grinding sleeve and the grinding table. Through the continuous rotation of the grinding table, and the fact that the inner wall of the grinding sleeve and the outer wall of the grinding table are both uneven, the blades can be further crushed to ensure the crushing quality.

[0017] 3. As described in point 2, after the blades are finely ground, the material falls into the support cylinder. The material can be retrieved through the notches on both sides. To prevent dust from being generated during retrieval, the power to motor 3 is turned on, which drives the shaft 3 to rotate, thus rotating the blades. The blades generate an airflow from the dust hood to the dust collection cylinder, which draws the dust into the dust collection cylinder. The dust is then blocked by the isolation net and collected in the inner cylinder, reducing the impact of dust on the surrounding environment and workers.

[0018] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0026] The following detailed description illustrates the specific implementation method:

[0027] Example

[0028] like Figures 1 to 6 As shown, a fine grinding device for mulberry leaf feed is disclosed, including a grinding mechanism 1, a drive mechanism 2 is arranged inside the grinding mechanism 1, and a dust removal mechanism 3 is arranged outside the grinding mechanism 1. The dust removal mechanism 3 is symmetrically distributed along the grinding mechanism 1.

[0029] The crushing mechanism 1 includes a cylinder 10. A feeding port 11 is provided through one side of the cylinder 10. The feeding port 11 is fixed to the cylinder 10 by welding. Dried and dehydrated mulberry leaves can be continuously fed into the cylinder 10 through the feeding port 11. An extension platform 12 is provided at the end of the cylinder 10 away from the feeding port 11. One end of the extension platform 12 is fixedly assembled to the outer wall of the cylinder 10 by screws. A support frame 13 is provided above the extension platform 12. The support frame 13 has a right-angle bent structure. Its end perpendicular to the horizontal direction is welded and fixed to the surface of the extension platform 12. A cylinder 14 is provided through the horizontal position of the support frame 13. The outer wall of the cylinder 14 is fixedly assembled to the top of the support frame 13 by a bracket. A piston rod for driving is provided inside the cylinder 14. Two sets of cylinders 14 are provided and arranged side by side. The piston rods of the two cylinders 14 are equipped with the same pressure block 15. The pressure block 15 is a cylindrical structure. The upper end of the pressure block 15 is fixed to the end of the piston rod by screws. The outer ring wall of the pressure block 15 is slidably sleeved with the inner ring wall of the cylinder 10. The pressure block 15 can assist in squeezing the material during the crushing process after the mulberry leaves are fed through the feeding interface 11, thereby ensuring that the material has a certain conveying and feeding capacity. A support cylinder 16 is provided below the cylinder 10. The support cylinder 16 is wrapped and positioned with the cylinder 10, and the connection between the support cylinder 16 and the cylinder 10 is fixed by welding. Notches 17 are opened at both ends of the support cylinder 16. The notches 17 can be used to remove the material after crushing. The height of the support cylinder 16 can be set according to actual needs to ensure that the notches 17 can discharge material normally.

[0030] A grinding sleeve 18 is provided at the lower end of the inner cavity of the cylinder 10. The grinding sleeve 18 is fixed to the cylinder 10 by screws. A grinding table 19 is provided through the inside of the grinding sleeve 18. The distance between the outer ring wall of the grinding table 19 and the inner ring wall of the grinding sleeve 18 is equal at any point. Grinding protrusions made of silicon carbide are provided on the inner ring wall of the grinding sleeve 18 and the outer ring wall of the grinding table 19. When mulberry leaves pass through the gap, they can be ground by the grinding sleeve 18 and the grinding table 19 to achieve further crushing. Several baffles 110 are also distributed on the inner wall of the cylinder 10. One end of the baffles 110 is welded to the inner ring wall of the cylinder 10. Several crushing columns 111 are distributed on the upper end of the outer ring wall of the grinding table 19. One end is welded to the outer surface of the grinding table 19. The crushing column 111 is placed above the baffle column 110. Several pointed protrusions 112 are distributed on the surface of the crushing column 111. One end of the pointed protrusion 112 is welded to the surface of the crushing column 111. The pointed protrusion 112 has a conical structure. When the grinding table 19 rotates, the material fed through the feeding interface 11 can fall above the grinding table 19. Through the centrifugal effect, it will be thrown to the edge and crushed by impact with the crushing column 111. The baffle column 110 can play a slowing effect, increase the contact time between the mulberry leaves and the crushing column 111. With the continuous pressing of the pressure block 15, when the amount of crushed mulberry leaves is increased, it can prevent the loose accumulation and the crushing work from stopping, thus ensuring the feeding progress.

[0031] A plurality of bearings 1001 are disposed through the surface of the cylinder 10. The outer ring wall of the bearings 1001 is fixed to the cylinder 10 by welding. A shaft 1002 is disposed through the interior of the bearings 1001. The surface of the shaft 1002 is press-fitted to the inner ring wall of the bearings 1001. A plurality of blades 1003 are disposed at the inward end of the shaft 1002. Each blade 1003 is welded to the surface of the shaft 1002. A motor 1004 is disposed at the outer end of the shaft 1002. The outer ring wall of the motor 1004 is fixed to the outer wall of the cylinder 10 by a bracket. The motor 1004 has a drive shaft inside. The end of the drive shaft is fixedly connected to the outer end of the shaft 1002 via a coupling. After the motor 1004 is powered on, the drive shaft can rotate the shaft 1002 and simultaneously drive the blade 1003. The mulberry leaves crushed by the impact of the crushing column 111 and the baffle column 110 above will continue to fall. Through the rotation of the blade 1003, the large mulberry leaves that cannot pass through the area of ​​the blade 1003 can be further crushed, ensuring stable processing of mulberry leaves from large to small.

[0032] The drive mechanism 2 includes a second bearing 20. The outer ring wall of the second bearing 20 is fixedly assembled to the inner wall of the support cylinder 16 via a bracket. A second shaft 21 is installed through the interior of the second bearing 20. The outer ring wall of the second shaft 21 is interference-fitted with the inner ring wall of the second bearing 20. The upper end of the second shaft 21 is positioned at the lower center of the grinding table 19, and the end face of the second shaft 21 is fixed to the surface of the grinding table 19 by welding. The second shaft 21 provides support for the grinding table 19 and simultaneously drives the grinding table 19 to rotate. A linkage bevel gear 22 is installed below the second shaft 21. The linkage bevel gear 22 is interference-fitted with the surface of the second shaft 21 and drives the bevel gear to rotate. Wheel 26 drives the linkage bevel gear 22 to rotate, which in turn enables the shaft 21 to rotate. Thus, based on the support of bearing 20, the rotation of the grinding table 19 can be ensured. When small pieces of mulberry leaves enter the grinding channel formed by the grinding table 19 and the grinding sleeve 18, they can be further crushed through the effect of rotational contact. The surface of shaft 21 is also covered with a centrifugal disc 23. The connection between the centrifugal disc 23 and shaft 21 is fixed by screws. When the crushed mulberry leaf material falls, the centrifugal disc 23 can avoid direct contact with bearing 20 and the transmission position of the bevel gear. Through centrifugal effect, the crushed material falls from the edge.

[0033] A bearing 24 is installed through the surface of the support cylinder 16. The bearing 24 is fixed to the support cylinder 16 by welding. A shaft 25 is installed through the interior of the bearing 24. The surface of the shaft 25 is interference-fitted with the inner ring wall of the bearing 24. A drive bevel gear 26 is installed at one end of the shaft 25 inside the support cylinder 16. The drive bevel gear 26 is interference-fitted with the shaft 25. The drive bevel gear 26 meshes with the linkage bevel gear 22. A second motor 27 is provided at the outer end. The outer wall of the second motor 27 is fixedly assembled to the surface of the support cylinder 16 through a bracket. The second motor 27 is provided with a second rotating shaft for driving. The end of the second rotating shaft is fixedly connected to the end of the third shaft 25 through a coupling. When the grinding table 19 needs to be driven, the power supply of the second motor 27 is turned on, so that the second rotating shaft can rotate and drive the third shaft 25 in linkage. Thus, the drive bevel gear 26 can mesh with the linkage bevel gear 22 to rotate.

[0034] The dust removal mechanism 3 includes a positioning plate 30, which is located above the notch 17. One end of the positioning plate 30 is fixedly assembled to the surface of the support cylinder 16 by screws. A dust suction hood 31 is installed through the interior of the positioning plate 30. The interface of the dust suction hood 31 is fixed to the interface of the positioning plate 30 by screws. An inner cavity 32 is provided inside the dust suction hood 31, which communicates with the interface of the dust suction hood 31. A mesh plate 33 is fixedly embedded in the opening of the inner cavity 32. After the material is crushed, it flows from the mesh plate 30 through the mesh plate 30. When material is discharged at notch 17, the motor 3005 drives the shaft 3 to rotate the blade 3006, thereby generating a suction effect from the dust hood 31 to the dust collection cylinder 3001, so that dust can be sucked into the dust hood 31 and transported to the dust collection cylinder 3001 through the connecting pipe 34. The mesh plate 33 can isolate large lint and dust to prevent them from entering the dust collection cylinder 3001. The upper flange of the interface of the dust hood 31 is connected to the connecting pipe 34.

[0035] Above the positioning plate 30, a dust collection cylinder 3001 is also provided. One end of the dust collection cylinder 3001 is connected to the end flange of the connecting pipe 34. Inside the dust collection cylinder 3001, at the end away from the connecting pipe 34, a grille 3002 is provided. The edge of the grille 3002 is fixedly assembled with the inside of the dust collection cylinder 3001. The grille 3002 can prevent the outside from directly contacting the blades 3006. Inside the dust collection cylinder 3001, an inner cylinder 3003 is provided. The edge of the inner cylinder 3003 is fixed to the inner wall of the dust collection cylinder 3001 by screws. A channel is provided through the inside of the inner cylinder 3003. The channel is wider at the front and narrower at the back. An isolation net 3004 is embedded and fixed at the narrow opening. The isolation net 3004 is made of non-woven fabric material, which can prevent dust from overflowing from the dust collection cylinder 3001 and can cooperate with the inner cylinder 3001. 03 serves to collect dust. Inside the dust collection cylinder 3001, there is also a motor 3005. The outer wall of the motor 3005 is fixedly assembled to the inside of the dust collection cylinder 3001 through a bracket. Inside the motor 3005, there is a rotating shaft 3 for driving. Several blades 3006 are fixed to the end of the rotating shaft 3. One end of the blades 3006 is fixedly assembled to the surface of the rotating shaft 3 through screws. When the motor 3005 is driven, the rotating shaft 3 can drive the blades 3006 to rotate and generate airflow, which can draw the air at the dust suction hood 31 into the dust collection cylinder 3001. The dust is isolated by the isolation net 3004 and collected inside the inner cylinder 3003. This prevents dust from being raised into the air when the crushed mulberry leaf raw material is taken out, thus avoiding harm to the surrounding environment and the health of workers.

[0036] In practice

[0037] When mulberry leaves need to be crushed, dehydrated and dried mulberry leaves can be fed into the cylinder 10 for crushing through the feeding interface 11. Then, the mulberry leaves will fall above the grinding table 19. The power of the motor 27 is turned on, so that the rotating shaft 2 can be driven, thereby enabling the drive bevel gear 26 to mesh with the linkage bevel gear 22 to rotate, and causing the shaft 21 to rotate. Thus, the grinding table 19 can be rotated. Through the centrifugal effect of the grinding table 19, the mulberry leaves can be thrown to the edge and come into contact with the crushing column 111. Through the impact contact between the tip protrusion 112 and the mulberry leaves, and with the delay of the falling of the baffle column 110, the mulberry leaves can fully interact with the tip protrusion 112, which can realize the operation of changing from large to small.

[0038] To prevent large mulberry leaves from being missed and not crushed, the power supply to motor 1004 can be turned on, so that motor 1004 can drive shaft 1, thereby realizing the rotation of shaft 1002, which in turn drives blade 1003 to rotate. Mulberry leaves that cannot pass through the area of ​​blade 1003 can be crushed. After being crushed from large to small, the mulberry leaves will enter the gap between grinding sleeve 18 and grinding table 19. Through the continuous rotation of grinding table 19, and the fact that the inner wall of grinding sleeve 18 and the outer wall of grinding table 19 are both uneven, the mulberry leaves can be further crushed to ensure the crushing quality.

[0039] After the mulberry leaves are ground into fine powder, they fall into the support cylinder 16. The powder can be picked up through the notches 17 on both sides. To avoid dust during the picking process, the power supply of motor 3005 is turned on, so that motor 3005 can drive the rotating shaft 3 to rotate, which can rotate the blades 3006. The blades 3006 can generate airflow from the dust suction hood 31 to the dust collection cylinder 3001, which can suck the dust into the dust collection cylinder 3001 and block it through the isolation net 3004, and collect it in the inner cylinder 3003, reducing the impact of dust on the surrounding environment and staff.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
