Description

Technical Field

[0001] This invention relates to the technical field of feed grinding, and in particular to a raw material processing device for rabbit feed production based on an energy-saving electric motor. Background Technology

[0002] Rabbit feed refers to specialized food provided for rabbits, designed to meet their daily nutritional needs and maintain healthy growth and development. Workers usually formulate feed formulas based on the nutritional requirements of rabbits. The fiber in rabbit feed typically comes from forage, such as hay or pasture. In the rabbit feed production process, hay is usually crushed using a hammer mill to break it into the specified particle size. After being crushed, the hay is mixed with other raw materials and granulated to become rabbit feed.

[0003] While existing hammer mills can effectively crush hay-like materials, they still have the following problems: When crushing hay-like materials, which are usually rich in fiber and have a relatively hard and complex fiber structure, if the hammers do not fully impact the hay, the crushing effect is insufficient. This leads to uncrushed hay accumulating on the filter screen. Additionally, there are often crushing dead zones in the mill, where some hay enters and cannot be crushed, accumulating on the filter screen. Prolonged accumulation causes filter screen blockage, slowing down the passage of fully crushed hay through the screen. This results in fully crushed hay remaining above the filter screen for extended periods without being discharged in time, and being repeatedly struck by the hammers or blades. Unnecessary secondary crushing not only increases energy consumption but also affects subsequent hay crushing. Furthermore, mills typically rely on airflow for assisted discharge; stagnant material can block the normal airflow, increasing the fan load and leading to increased motor power consumption. Summary of the Invention

[0004] In view of the problem that existing technologies have problems such as hay clogging the filter screen, which causes the hammer to repeatedly crush the remaining hay after crushing, resulting in unnecessary secondary crushing, increasing the load on the motor and energy consumption, a raw material processing equipment for rabbit feed production based on an energy-saving electric motor is proposed.

[0005] This application provides a raw material processing device for rabbit feed production based on an energy-saving electric motor. The purpose is to: by setting an anti-retention component on the outer wall of the rotor ring, the fixed and movable blades can collect the uncrushed hay accumulated on the annular filter screen during periodic rotation and bring it to the hammer for re-crushing. At the same time, the trigger component can automatically cut off the hay wrapped around the blades when the movable blades move directly above the hammer, preventing the hay from getting tangled on the blades. This effectively avoids the situation where the filter screen is blocked and the crushed hay cannot flow out, and the hammer performs unnecessary secondary crushing of the crushed hay, which would increase the motor load and energy consumption.

[0006] The technical solution of the present invention is: a raw material processing equipment for rabbit feed production based on an energy-saving electric motor, including a servo motor, a rotor ring disposed on the drive end of the servo motor, a production unit installed on the outer wall of the rotor ring, and the production unit including an anti-retention component disposed on the outer wall of the rotor ring; The anti-retention component includes multiple connecting rods disposed on the outer walls of both ends of the rotor ring, a synchronizing ring disposed on one end of the corresponding multiple connecting rods, a connecting plate disposed between two synchronizing rings, a fixed blade net disposed on the side wall of the connecting plate, mounting plates disposed on the upper walls of both ends of the connecting plate, a rotating shaft disposed between two mounting plates, and a movable blade net disposed on the outer wall of the rotating shaft. Both ends of the rotating shaft are equipped with trigger components. Both the movable and fixed blades consist of multiple blades, which are interlaced. The fixed and movable blades are used to wrap the trapped fibers around their own blades. The triggering component is used to drive the movable blade to deflect, and the deflection of the movable blade is used to cut the fibers wrapped around the blades.

[0007] Furthermore, it also includes multiple support legs, the upper ends of which are collectively provided with a support plate. A housing is provided on the upper end of the support plate. A feed pipe is provided on the upper end of the housing. An inlet is opened on the upper end of the feed pipe. An outlet is opened on the lower end of the housing. A first placement plate and a second placement plate are installed on the side wall of the housing. A filter assembly is installed inside the housing.

[0008] Furthermore, the filter assembly includes two support plates disposed on both sides of the inner wall of the chassis, two spring support rods respectively disposed on the upper part of the two support plates, a base plate disposed on the upper part of the corresponding two spring support rods, and an annular filter screen disposed between the two base plates. The lower end of the annular filter screen has multiple filter holes. The two synchronous rings are located inside the annular filter screen, and the axis of the synchronous rings is the same as the axis of the annular filter screen. The lower end of the fixed blade is arc-shaped, and the lower end of the fixed blade is in contact with the inner wall of the annular filter screen.

[0009] Furthermore, the production unit also includes a crushing component, which includes a drive rotor mounted on the side wall of the chassis. The end of the drive rotor away from the servo motor is fixedly connected to a drive motor. The drive rotor is rotatably mounted inside the rotor ring. Multiple liner plates are mounted on the outer wall of the drive rotor. Multiple connecting pins are mounted on the side walls of two adjacent liner plates. Hammers are respectively mounted on the outer walls of the multiple connecting pins. When the hammers rotate, the movable blade is not within the rotation range of the hammers. The drive motor is fixedly mounted on a first placement plate. A shaft seat is fixedly mounted on a second placement plate. The drive rotor is rotatably mounted on the shaft seat.

[0010] Furthermore, the triggering assembly includes trigger rings disposed on the outer walls at both ends of the rotating shaft, a trigger rod disposed at the lower end of the trigger rings, a torsion spring disposed between the trigger rings and the mounting plate, and a mating element installed between the annular filter screen and the trigger rod.

[0011] Furthermore, the mating element includes annular grooves formed on both sides of the inner wall of the annular filter screen, the lower end of the trigger rod is located in the annular groove, and a mating protrusion is provided in the annular groove, the mating protrusion being located above the left side of the rotor ring.

[0012] Furthermore, the upper end of the annular filter screen is provided with a connecting hole, and the feed inlet is fixedly connected to the connecting hole.

[0013] Furthermore, a receiving hopper is placed at the lower end of the discharge port, and the receiving hopper is used to collect the crushed material.

[0014] The beneficial effects of this invention are: 1. By setting up anti-retention components, the servo motor can control the deflection of the fixed and movable blades at regular intervals. During the deflection process, the blades can automatically screen out the hay accumulated on the filter screen and carry it away from the filter opening of the annular filter screen. This effectively avoids the situation where the shredded hay is stuck inside the annular filter screen due to the accumulation of hay. This improves the feeding efficiency of the shredded hay and avoids unnecessary secondary shredding of the shredded hay by the hammer. It effectively reduces the energy consumption and load of the shredding device and has an energy-saving effect.

[0015] 2. By setting a trigger component, when the movable and fixed blades rotate to directly above the hammer head, the trigger component and the cooperating element work together to drive the movable blade to deflect. During the deflection process, the movable blade can cut the hay wrapped around the blades, preventing the hay from being wrapped around the blades for a long time and affecting the subsequent collection of incompletely crushed hay.

[0016] 3. By regularly collecting and re-crushing the dry grass accumulated on the filter screen, not only is the energy consumption of the crusher reduced during operation, but the regular cleaning also ensures the continuous operation of the crusher. There is no need to stop the machine regularly and clean the ring filter screen manually, which effectively reduces the workload of the staff while improving the crushing efficiency and quality of the crusher.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1, referring to Figures 3-8 as well as Figure 10 The first embodiment of the present invention provides a raw material processing device for rabbit feed production based on an energy-saving electric motor, including a servo motor (not shown in the figure), a rotor ring 2 fixedly installed on the drive end of the servo motor, a production unit installed on the outer wall of the rotor ring 2, and the production unit including an anti-retention component installed on the outer wall of the rotor ring 2.

[0021] The anti-retention component includes multiple connecting rods 3 fixedly installed on the outer walls of both ends of the rotor ring 2, a synchronous ring 4 fixedly installed on one end of the corresponding multiple connecting rods 3, a connecting plate 5 fixedly installed between two synchronous rings 4, a fixed blade net 6 fixedly installed on the side wall of the connecting plate 5, a mounting plate 7 fixedly installed on the upper walls of both ends of the connecting plate 5, a rotating shaft 8 rotatably installed between two mounting plates 7, a movable blade net 9 fixedly installed on the outer wall of the rotating shaft 8, and trigger components installed at both ends of the rotating shaft 8.

[0022] Both the movable blade net 9 and the fixed blade net 6 are composed of multiple blades, and the blades of the two are interlaced. The fixed blade net 6 and the movable blade net 9 are used to wrap the trapped fibers around their own blades. The triggering component is used to drive the movable blade net 9 to deflect. The deflection of the movable blade net 9 is used to cut the fibers wrapped around the blades.

[0023] Specifically, the connecting rod 3 and the synchronous ring 4 serve as transmission mechanisms. When the servo motor drives the rotor ring 2 to rotate via the drive end, it will cause the fixed blade 6 and the movable blade 9 to deflect around the rotor ring 2 via the connecting rod 3 and the synchronous ring 4. During the movement, the fixed blade 6 and the movable blade 9 can sieve the uncrushed hay and drive the sieved hay to move synchronously through their own speed. By setting the parameters of the servo motor, the operator can make the servo motor rotate once at regular intervals. When the servo motor is in its initial position, the fixed blade 6 and the movable blade 9 are at the top. After the drive end of the servo motor rotates once, the fixed blade 6 and the movable blade 9 will eventually stop at the top. The hay collected above the fixed blade 6 and the movable blade 9 will fall under the action of gravity and be crushed again after losing speed.

[0024] The movable blade screen 9 and the fixed blade screen 6 consist of multiple blades with gaps between adjacent blades. When these blades move and pass through the pulverized hay, they automatically sieve out any unpulverized hay. The sieved hay moves synchronously with the blades due to their speed, essentially "adhering" to them. When the blades reach their highest point and stop, the hay, having lost speed, falls under gravity and undergoes secondary pulverization. This design ensures that the pulverized hay flows out of the device promptly and allows for automatic processing of incompletely pulverized hay without requiring manual intervention.

[0025] By ensuring that the hay flows out after shredding, the problem that occurs in existing hammer mills, where incompletely shredded hay accumulates on the filter screen and causes blockage, will not occur. This prevents the shredded hay from flowing out of the device at a normal speed, causing it to remain inside the device for a longer period. This retention of hay will force the device to perform unnecessary secondary shredding, increasing the load on the shredding device and energy consumption.

[0026] The machine eliminates the need for staff to stop and manually process the incompletely shredded hay, ensuring continuous operation of the shredding unit, effectively improving the production efficiency and quality of the shredder, reducing the workload of staff, and enhancing safety during equipment maintenance.

[0027] It also includes multiple support legs 10, with a support plate 11 fixedly mounted on the upper end of each support leg 10. A housing 12 is fixedly mounted on the upper end of the support plate 11, and a feed pipe 13 is fixedly mounted on the upper end of the housing 12. The feed pipe 13 has a feed inlet 14 at its upper end, and a discharge outlet 15 at the lower end of the housing 12. A first placement plate 30 and a second placement plate 31 are mounted on the side wall of the housing 12, and a filter assembly is installed inside the housing 12. A collection hopper is placed at the lower end of the discharge outlet 15 to collect the crushed material.

[0028] The support leg 10 is used to raise the overall height of the device so that the receiving hopper can be placed normally below the discharge port 15. The receiving hopper is used to collect the completely crushed hay. The feed pipe 13 is used to input the hay to be crushed into the device for crushing.

[0029] Example 2, refer to Figures 1-5 as well as Figure 9 This is the second embodiment of the present invention, which differs from the first embodiment in that: the production unit further includes a crushing component, which includes a drive rod 21 rotatably mounted on the side wall of the housing 12. A drive motor 1 is fixedly connected to the end of the drive rod 21 away from the servo motor. The drive rod 21 is rotatably mounted inside the rotor ring 2. Multiple liner plates 22 are fixedly mounted on the outer wall of the drive rod 21. Multiple connecting pins 23 are fixedly mounted on the side walls of two adjacent liner plates 22. Hammers 24 are rotatably mounted on the outer walls of the multiple connecting pins 23. When the hammers 24 rotate, the movable blade screen 9 is not within the rotation range of the hammers 24. The drive motor 1 is fixedly mounted on the first placement plate 30, and a shaft seat 32 is fixedly mounted on the second placement plate 31. The drive rod 21 is rotatably mounted on the shaft seat 32. A connecting hole 29 is provided at the upper end of the annular filter screen 19, and the feed inlet 14 is fixedly connected to the connecting hole 29.

[0030] Specifically, the crushing component is used to crush the hay. The drive motor 1 drives the drive rod 21 to rotate synchronously, and the rotation of the drive rod 21 drives the hammer 24 on the liner 22 to rotate at high speed. During the high-speed rotation of the hammer 24, it collides with the hay at the feed inlet 14. During the collision, the hay is crushed under the impact force. The crushed hay falls directly above the hammer 24 through the connecting hole 29, so that the hammer 24 can better crush the hay fed into the interior.

[0031] Reference Figures 1-2 The filter assembly includes two support plates 16 fixedly installed on both sides of the inner wall of the housing 12, two spring support rods 17 fixedly installed on the upper ends of the two support plates 16 respectively, base plates 18 fixedly installed on the upper ends of the corresponding two spring support rods 17, and an annular filter screen 19 fixedly installed between the two base plates 18. The lower end of the annular filter screen 19 has multiple filter holes 20. Two synchronous rings 4 are located inside the annular filter screen 19, and the axis of the synchronous rings 4 is the same as the axis of the annular filter screen 19. The lower end of the fixed blade screen 6 is arc-shaped, and the lower end of the fixed blade screen 6 is in contact with the inner wall of the annular filter screen 19.

[0032] Specifically, the filter assembly is used to filter the shredded hay. Completely shredded hay can pass through the annular filter screen 19 and fall directly into the collection hopper, while uncrushed hay is blocked at the top by the annular filter screen 19. When too much uncrushed hay accumulates on the annular filter screen 19, it will clog the filter holes 20. Once the filter holes 20 are clogged with hay, the completely shredded hay cannot pass through. As more and more completely shredded hay accumulates and the longer it remains, the rotating hammer 24 will further clog the shredded hay. The hay needs to be shredded a second time, but this is unnecessary. It would not only increase the load and energy consumption of the drive motor 1, but also affect the subsequent shredding of hay. Therefore, by setting up an annular filter screen 19 and an anti-retention component, the two work together to intermittently collect the incompletely shredded hay on the annular filter screen 19. This not only prevents the hay from clogging the annular filter screen 19, but also enables the automatic reintroduction of the incompletely shredded hay into the hammer head 24 for secondary shredding, avoiding waste and achieving two goals at once.

[0033] The annular filter screen 19 is fixed by the spring support rod 17, allowing it to vibrate synchronously with the servo motor and drive motor 1 through the vibration generated by their rotation. This vibration has two advantages: firstly, it accelerates the outflow of completely pulverized hay, effectively reducing the residence time of hay within the device and improving pulverization efficiency; secondly, the vibration of the annular filter screen 19 causes the partially pulverized hay blocking the flow above to vibrate synchronously. When the fixed blade 6 and movable blade 9 deflect and pass through the hay, the vibration of the hay above makes it easier for the fixed blade 6 to carry the hay, preventing it from sticking tightly to the top of the annular filter screen 19 and failing to be carried away by the fixed blade 6.

[0034] The remaining structure is the same as that in Example 1.

[0035] Example 3, referring to Figures 4-8 as well as Figure 11 This is the third embodiment of the present invention, which differs from the second embodiment in that: the triggering assembly includes trigger rings 25 disposed on the outer walls of both ends of the rotating shaft 8, a trigger rod 26 disposed at the lower end of the trigger rings 25, a torsion spring 27 disposed between the trigger rings 25 and the mounting plate 7, and a mating element installed between the annular filter screen 19 and the trigger rod 26. The mating element includes annular grooves 33 formed on both sides of the inner wall of the annular filter screen 19, the lower end of the trigger rod 26 located in the annular grooves 33, and a mating protrusion 28 disposed in the annular grooves 33, the mating protrusion 28 being located on the upper left side of the rotor ring 2.

[0036] Specifically, the triggering component and the cooperating element work together so that whenever the fixed blade 6 and the movable blade 9 are about to rotate one revolution to the highest point (initial position), the triggering rod 26 can press against the cooperating protrusion 28, so that the cooperating protrusion 28 generates a pushing force on the triggering rod 26, which drives the movable blade 9 on the rotating shaft 8 to rotate. During the rotation, the movable blade 9 can cooperate with the fixed blade 6 to cut the hay wrapped around the blades, ensuring that the hay wrapped around the blades can fall smoothly to the hammer head 24 for secondary crushing by gravity.

[0037] The remaining structure is the same as that in Example 2.

[0038] Based on embodiments 1-3, the working principle of the present invention is as follows: The operator turns on the drive motor 1 and the servo motor. The drive motor 1 drives the hammer 24 on the outer wall to rotate synchronously through the drive rod 21. At this time, the hay to be crushed enters the interior of the annular filter screen 19 through the feed pipe 13. The rotating hammer 24 crushes the hay that enters. The completely crushed hay falls into the collection hopper under the action of gravity for collection. At the same time, the filter holes 20 on the annular filter screen 19 block the hay that is not completely crushed. The hay that is not completely crushed accumulates inside the annular filter screen 19.

[0039] The servo motor drives the rotor ring 2 to rotate periodically via the drive end. During the rotation of the rotor ring 2, the fixed blade 6 and the movable blade 9 on the connecting plate 5 can be deflected one revolution through the synchronous ring 4. When the fixed blade 6 and the movable blade 9 are deflected to the bottom of the annular filter screen 19, they can drive the uncrushed hay to move synchronously. At the same time, in coordination with the vibrating annular filter screen 19, the hay that was originally attached to the top of the annular filter screen 19 can be bounced up during vibration, making it easier for the fixed blade 6 to sieve and remove the hay at the corresponding position when it moves to the corresponding position. When the fixed blade 6 and the movable blade 9 sieve out the uncrushed hay, their own speed will drive the hay to move synchronously. The hay is "adsorbed" onto the blades by the speed of the fixed blade 6 and the movable blade 9, so that the hay will move synchronously with the fixed blade 6 and the movable blade 9.

[0040] As the fixed blade 6 and the movable blade 9 approach their highest point, the trigger rods 26 at both ends of the rotating shaft 8 contact and press against the mating protrusions 28. Under pressure, the trigger rods 26 deflect, causing the movable blade 9 to deflect synchronously. During this deflection, the movable blade 9 and the fixed blade 6 work together to cut the hay wrapped around the blades, allowing the hay on both the fixed and movable blades 6 to fall to the hammer head 24 for secondary crushing under gravity. This prevents the annular filter screen 19 from clogging and allows any incompletely crushed hay to be fed back into the hammer head 24 for secondary crushing.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
