Description

Technical Field

[0001] The invention relates to the technical field of feed crushing, and in particular to raw material processing equipment for rabbit feed production based on an energy-saving motor. Background Art

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

[0003] Although the existing hammer grinder can effectively crush hay materials, the following problems still exist: when the existing hammer grinder crushes hay materials, because hay materials are usually rich in fiber, and their fiber structure is relatively hard and complex, if the hammer of the grinder does not fully hit the hay, the hay crushing effect is insufficient, and the uncrushed hay will be accumulated on the filter. At the same time, there are usually dead corners of crushing in the grinder. Some hay enters the dead corners of crushing and cannot be crushed and accumulates on the filter. Long-term accumulation will cause the filter to be blocked, and the speed at which the completely crushed hay passes through the filter will slow down, resulting in the completely crushed hay being retained above the filter for a long time and not discharged in time. It will be repeatedly hit by hammers or blades. Unnecessary secondary crushing will not only increase energy consumption, but also affect the subsequent hay crushing. At the same time, the grinder usually relies on airflow to assist in discharging, and the retained matter will block the normal flow of airflow, increase the fan load, and cause the motor power consumption to increase. Summary of the invention

[0004] In view of the problem in the prior art that hay blocks the filter screen, causing the hammer to repeatedly and unnecessarily grind the remaining hay after it has been crushed, thereby increasing the load and energy consumption of the motor, a raw material processing equipment for rabbit feed production based on an energy-saving motor is proposed.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

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

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

[0022] The movable knife net 9 and the fixed knife net 6 are both composed of multiple blades, and the blades of the two are staggered. The fixed knife net 6 and the movable knife net 9 are used to wrap the retained fibers around their own blades. The trigger component is used to drive the movable knife net 9 to deflect, and the deflection of the movable knife net 9 is used to cut the fibers wrapped around the blades.

[0023] Specifically, the connecting rod 3 and the synchronous ring 4 play a transmission role. When the servo motor drives the rotor ring 2 to rotate through the driving end, the fixed knife net 6 and the movable knife net 9 will be driven to deflect with the rotor ring 2 as the axis through the connecting rod 3 and the synchronous ring 4. During the movement, the fixed knife net 6 and the movable knife net 9 can screen the uncrushed hay and drive the screened hay to move synchronously through their own movement speed. The staff sets the parameters of the servo motor so that the servo motor can rotate one circle at a certain interval. When the servo motor is in the initial position, the fixed knife net 6 and the movable knife net 9 are located at the top. After the servo motor driving end rotates one circle, the fixed knife net 6 and the movable knife net 9 will finally stay at the top. The hay screened and collected above the fixed knife net 6 and the movable knife net 9 will fall under the action of gravity and be crushed again after losing speed.

[0024] The movable knife net 9 and the fixed knife net 6 are composed of multiple blades, and there is a gap between two adjacent blades. When the multiple blades are moving and passing through the inside of the crushed grass, the uncrushed hay inside can be automatically screened. The screened hay will move synchronously with the blades under the action of the speed of the blade movement, which is equivalent to being "adsorbed" on the blades. When the blades move to the highest point and stop, the hay that loses speed will fall under the action of gravity and be crushed again. This design can ensure that the hay after crushing can flow out of the device in time, and can automatically handle the hay that is not completely crushed inside without the staff stopping the machine for processing.

[0025] By ensuring that the hay flows out of the device after being crushed, the problem that occurs in the existing hammer mill, that is, when the incompletely crushed hay accumulates on the filter screen and causes blockage, the crushed hay cannot flow out of the device at a normal speed, so that the crushed hay will be retained in the device for a longer time, and the retention of hay will cause the device to perform unnecessary secondary crushing on the hay, thereby increasing the load and energy consumption of the crushing device, will not occur.

[0026] There is no need for staff to stop the machine to manually handle the incompletely crushed hay, which can ensure the continuous operation of the crushing device, effectively improve the production efficiency and quality of the crusher, effectively reduce the workload of staff, and improve the safety of device maintenance.

[0027] It also includes a plurality of support legs 10, a support plate 11 is fixedly mounted on the upper ends of the plurality of support legs 10, a chassis 12 is fixedly mounted on the upper ends of the support plates 11, a feed pipe 13 is fixedly mounted on the upper ends of the chassis 12, a feed port 14 is provided on the upper ends of the feed pipe 13, a discharge port 15 is provided on the lower ends of the chassis 12, a first placement plate 30 and a second placement plate 31 are installed on the side walls of the chassis 12, and a filter assembly is installed inside the chassis 12. A receiving hopper is placed at the lower end of the discharge port 15, and the receiving hopper is used to collect the crushed material.

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

[0029] Example 2, reference Figures 1 - 5 as well as Figure 9 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the production unit also includes a crushing component, which includes a driving rod 21 rotatably mounted on the side wall of the chassis 12, the end of the driving rod 21 away from the servo motor is fixedly connected to the driving motor 1, the driving rod 21 is rotatably mounted inside the rotor ring 2, a plurality of lining plates 22 are fixedly mounted on the outer wall of the driving rod 21, a plurality of connecting pins 23 are fixedly mounted on the side walls of two adjacent lining plates 22, and hammers 24 are rotatably mounted on the outer walls of the plurality of connecting pins 23, respectively, when the hammers 24 rotate, the movable knife net 9 is not within the rotation range of the hammers 24, the driving motor 1 is fixedly mounted on the first placement plate 30, the second placement plate 31 is fixedly mounted with a shaft seat 32, and the driving rod 21 is rotatably mounted on the shaft seat 32. A connecting hole 29 is provided at the upper end of the annular filter 19, and the feed port 14 is fixedly connected to the connecting hole 29.

[0030] Specifically, the crushing component is used to crush the hay. The driving end of the driving motor 1 drives the driving rod 21 to rotate synchronously, and the rotation of the driving rod 21 drives the hammer head 24 on the lining plate 22 to rotate at a high speed. During the high-speed rotation of the hammer head 24, it collides with the hay at the feed port 14. During the collision, the hay is crushed under the action of the impact force. The hay to be crushed falls directly above the hammer head 24 through the connecting hole 29, so that the hammer head 24 can better crush the hay input into the inside.

[0031] Reference Figures 1 - 2 The filter assembly includes two bearing plates 16 fixedly mounted on both sides of the inner wall of the chassis 12, two spring support rods 17 respectively fixedly mounted on the upper ends of the two bearing plates 16, a base plate 18 fixedly mounted on the upper ends of the two corresponding spring support rods 17, and an annular filter screen 19 fixedly mounted between the two base plates 18. A plurality of filter holes 20 are provided at the lower end of the annular filter screen 19. Both of the two synchronous rings 4 are located inside the annular filter screen 19, and the axis of the synchronous ring 4 is the same as the axis of the annular filter screen 19. The lower end of the fixed knife net 6 is arc-shaped, and the lower end of the fixed knife net 6 is in contact with the inner wall of the annular filter screen 19.

[0032] Specifically, the filter assembly is used to filter the crushed hay. The completely crushed hay can pass through the annular filter 19 and fall directly into the receiving hopper, while the uncrushed hay will be blocked by the annular filter 19 just above. When too much uncrushed hay accumulates on the annular filter 19, the filter hole 20 will be blocked. After the filter hole 20 is blocked by the hay, the completely crushed hay cannot pass through the filter hole 20. As the completely crushed hay accumulates more and the retention time is longer, the rotating hammer 24 will The hay is crushed twice, but the secondary crushing is unnecessary, which will not only increase the load and energy consumption of the driving motor 1, but also affect the subsequent crushing of the hay. Therefore, the annular filter 19 and the anti-retention component are arranged to cooperate with each other to intermittently collect and process the incompletely crushed hay on the annular filter 19, which not only prevents the hay from clogging the annular filter 19, but also realizes that the incompletely crushed hay can be automatically brought back to the hammer head 24 for secondary crushing, avoiding waste and killing two birds with one stone.

[0033] The annular filter 19 is fixed by the spring support rod 17, so that the annular filter 19 can be driven to vibrate synchronously through the vibration generated by the rotation of the servo motor and the drive motor 1. The vibration of the annular filter 19 has two advantages. One advantage is that the annular filter 19 can speed up the outflow efficiency of the completely crushed hay during the vibration process, effectively reduce the retention time of the hay in the device, and improve the crushing efficiency. Another advantage is that when the annular filter 19 vibrates, it will drive the incompletely crushed hay blocked above to vibrate synchronously. When the fixed knife net 6 and the movable knife net 9 deflect and pass through the hay, the vibration of the hay above makes the fixed knife net 6 more easily drive the hay, preventing the hay from being tightly attached to the top of the annular filter 19 and unable to be taken away by the fixed knife net 6.

[0034] The remaining structures are the same as those of Example 1.

[0035] Example 3, reference Figures 4 - 8 as well as Figure 11 , which is the third embodiment of the present invention, is different from the second embodiment in that the trigger assembly includes a trigger ring 25 arranged on the outer wall at both ends of the rotating shaft 8, a trigger rod 26 arranged at the lower end of the trigger ring 25, a torsion spring 27 arranged between the trigger ring 25 and the mounting plate 7, and a matching element is installed between the annular filter 19 and the trigger rod 26. The matching element includes an annular groove 33 opened on both sides of the inner wall of the annular filter 19, the lower end of the trigger rod 26 is located in the annular groove 33, and a matching protrusion 28 is arranged in the annular groove 33, and the matching protrusion 28 is located on the upper left side of the rotor ring 2.

[0036] Specifically, the function of the trigger assembly and the matching element is that the two cooperate with each other. Whenever the fixed knife net 6 and the movable knife net 9 are about to rotate one circle to the highest point (initial position), the trigger rod 26 can press against the matching protrusion 28, so that the matching protrusion 28 generates a thrust on the trigger rod 26, driving the movable knife net 9 on the rotating shaft 8 to rotate. During the rotation process, the movable knife net 9 can cooperate with the fixed knife net 6 to cut the hay wrapped around the blades of the two, ensuring that the hay wrapped around the blades can smoothly fall to the hammer head 24 through gravity for secondary crushing.

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

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

[0039] The servo motor drives the rotor ring 2 to rotate regularly through the driving end. During the rotation of the rotor ring 2, the fixed knife net 6 and the movable knife net 9 on the connecting plate 5 can be driven to deflect one circle through the synchronous ring 4. When the fixed knife net 6 and the movable knife net 9 are deflected to the bottom of the annular filter net 19, the fixed knife net 6 and the movable knife net 9 can drive the uncrushed hay to move synchronously, and at the same time cooperate with the vibrating annular filter net 19 to make the hay that was originally close to the top of the annular filter net 19 bounce up during vibration, making it easier to screen and remove the hay at the corresponding position when the fixed knife net 6 moves to the corresponding position. When the fixed knife net 6 and the movable knife net 9 screen out the uncrushed hay, their own speed will drive the hay to move synchronously. The hay is equivalent to being "adsorbed" on the blade due to the speed of the fixed knife net 6 and the movable knife net 9, so that the hay will move synchronously with the fixed knife net 6 and the movable knife net 9.

[0040] When the fixed blade net 6 and the movable blade net 9 are about to move to the highest point, the trigger rods 26 and the matching protrusions 28 at both ends of the rotating shaft 8 contact and press each other, and the trigger rods 26 deflect under the action of pressure, thereby driving the movable blade net 9 to deflect synchronously. During the deflection process, the movable blade net 9 cooperates with the fixed blade net 6 to shear the hay wrapped around the blade, so that the hay on the fixed blade net 6 and the movable blade net 9 can fall to the hammer head 24 for secondary crushing under the action of gravity. At this time, the annular filter 19 is prevented from being blocked, and the hay that is not completely crushed can be re-input 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 rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
