Description

Technical Field

[0001] This invention belongs to the field of pelleting, and in particular relates to a pellet mill for mixed grass feed. Background Technology

[0002] Feed is an important guarantee for the healthy growth and productivity of livestock. It can provide livestock with the basic nutrients needed for growth, such as protein, fat, carbohydrates, vitamins and minerals. Workers usually mix feeds containing different nutrients together. Scientifically formulated feed can better meet the nutritional needs of livestock at different growth stages, reducing feeding costs while increasing the economic benefits for farmers.

[0003] In existing technologies, by using a pellet mill to compress prepared crushed feed into feed strips, compared to directly feeding crushed feed, livestock can reduce waste and improve feed utilization when eating feed strips. The compressed feed strips are relatively hard, which can also help livestock grind their teeth when chewing. In addition, the feed in strip shape has a higher density, which reduces the volume of the feed, making it easier to package and transport. It also prevents problems such as feed getting damp and moldy to a certain extent, thus extending the shelf life of the feed.

[0004] However, existing pellet mills still have some shortcomings in the pelleting process:

[0005] 1. In traditional pellet mills, the extrusion plate used to extrude feed sludge is usually a single piece. It requires a large lateral span during extrusion, which occupies most of the machine's space. Furthermore, if it is damaged, the entire extrusion plate needs to be replaced.

[0006] 2. During the addition of crushed feed and mixing process, the pellet mill will generate a lot of dust, which will overflow from the feed inlet and outlet, affecting the operating environment and the health of the workers. Although some pellet mills are equipped with dust collectors, they still need to be cleaned manually regularly. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a mixed grass pellet feed pellet mill, comprising a machine body shell, a grinding disc, a mixer, a steam conveyor, a material conveyor, and a support body. The mixer, steam conveyor, and material conveyor are fixedly connected to the support body. The machine body shell is rotatably connected to the support body. The grinding disc is fixedly connected to the mixer. The grinding disc is circular with an opening at one end and has shaping holes. Multiple partitions are fixedly connected to the inner wall of the grinding disc. The free ends of the multiple partitions are fixedly connected to the same retaining ring. Adjacent partitions... An arc-shaped chamber is formed between the wall and the grinding disc, and each chamber has the same curvature. The opposite sides of the partition wall are slidably connected to a first pusher plate. The first pusher plates in the same chamber are slidably connected to the same second pusher plate. When the first pusher plate and the second pusher plate are at the starting point, the first pusher plate and the second pusher plate are distributed in a stepped manner. The first pusher plate, the second pusher plate and the inner wall of the grinding disc form a material storage area. The side of the second pusher plate away from the first pusher plate is fixedly connected to a telescopic slide bar and an extrusion structure. The telescopic end of the telescopic slide bar is slidably connected to the partition wall.

[0008] The agitator is provided with a feed inlet, and the output ports of the steam conveyor and the material conveyor are located above the feed inlet. A circulating dust suppression structure is symmetrically installed on the support body. The circulating dust suppression structure includes a flow pipe and a guide block. The two ends of the flow pipe are open. Multiple guide blocks are provided and detachably installed on the flow pipe.

[0009] Furthermore, the sides of both the first and second pusher plates opposite the pressing disc are arc-shaped, and the arc surface is 1 / 3 of the inner arc surface of the cavity. The thickness of the second pusher plate is the same as that of the first pusher plate. A sliding groove is provided on one side of the upper surface of the partition wall, and a slider is slidably connected to the sliding groove. The slider is fixedly connected to the first pusher plate. The partition wall is provided with a hole, and a first spring is fixedly connected in the hole. The other end of the first spring is fixedly connected to the slider.

[0010] Furthermore, the first pusher plate has an inclined surface on its side, and the two opposite sides of the second pusher plate have top blocks that are adapted to the inclined surface, and the top blocks are slidably connected to the inclined surface.

[0011] The extrusion structure includes a rotary motor, a rotary spindle, a push plate, and a gear disk. The rotary motor is fixedly connected in the outer casing of the machine body, and the output shaft of the rotary motor is detachably connected to the rotary spindle.

[0012] The rotating main shaft is located at the center of the retaining ring and is rotatably connected to the rolling disc;

[0013] The push plate is T-shaped with its vertical end passing through the retaining ring and fixedly connected to the second push plate. The other end of the push plate is fixedly connected to a support, and a gear is rotatably connected to the support. A second spring is also fixedly connected to the support, and the other end of the second spring is fixedly connected to the retaining ring.

[0014] The gear disk is fixedly connected to the rotating spindle and meshes with the gear. The gear disk includes multiple arc-shaped protrusions and transition sections. The transition section is located between two adjacent protrusions, and the distance from the highest point of the protrusion to the lowest point of the transition section is twice the thickness of the second push plate.

[0015] Furthermore, the mixer is equipped with a mixing impeller and a feeder. The feed inlet is located above the mixing impeller. Multiple feeders are provided, and each feeder corresponds to a storage area. The input port of the feeder is connected to the interior of the mixer, and the output port is connected to the storage area. The feeder is electrically connected to a push-button switch, and the free end of the push-button switch extends through the grinding disc.

[0016] The feeder's output port is located in the storage area. When the first pusher plate and the second pusher plate are at the starting point, the second pusher plate is located directly above the push-button switch, and the push-button switch is in the pressed state. The feeder's output port is located in front of the push-button switch.

[0017] Furthermore, an outer sealing plate is fixedly connected to the shaft of the rotating spindle. The outer sealing plate is rotatably connected to the open end of the crushing disc. Cutting blades extend outward from the outer sealing plate. The number of cutting blades is the same as the number of storage areas. The cutting blades are slidably connected to the disc body of the crushing disc.

[0018] Furthermore, the guide block is rhomboid in shape, and multiple baffles are provided on the two adjacent long sides of the guide block. Each of the multiple baffles is fitted with a dust collection frame, and several spike-shaped dust collection top columns are fixedly connected to the dust collection frame.

[0019] Furthermore, multiple guide plates are rotatably connected to the two opposing inner sidewalls of the flow tube, and the guide plates are located between two adjacent guide blocks.

[0020] Furthermore, a first pair of interfaces is provided on the side wall of the flow pipe near the agitator. One of the first pair of interfaces is fitted with a sealing cap, and the other first pair of interfaces is detachably fitted with a pipe. The pipe is adapted to the flow pipe and its end abuts against the inner wall of the flow pipe. A flow port is provided on one side of the pipe and is connected to the flow pipe. A pressure pump is fixedly connected to the other end of the pipe and is connected to the material conveyor.

[0021] Furthermore, a first fan and a second fan are detachably installed on the two flow pipes respectively. The first fan and the second fan are each provided with two air inlets. The air inlet of the first fan is connected to the end of one of the flow pipes away from the agitator, and a mesh is installed on the other air inlet.

[0022] The air outlet of the second fan is connected to the end of another flow pipe away from the agitator. A mesh screen is installed on the other air outlet, and the two air outlets with mesh screens are opposite each other.

[0023] The pipe is located on a flow pipe connected to the air outlet;

[0024] The sealing cap is located on the flow pipe that is connected to the air inlet.

[0025] Furthermore, a discharge port is provided at the bottom of the machine body shell, the discharge port is located below the grinding disc, two air vents with partitions are located between the discharge port and the grinding disc, and a collection box is provided below the discharge port.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In this invention, when the second pusher plate is pulled back, during the process of the second pusher plate being pulled out from between the two first pusher plates, the first spring returns to its original position and contracts, causing the slider to slide backward, which in turn causes the first pusher plate to slide backward. As the two first pusher plates slide, the lateral span between the two first pusher plates gradually decreases. When the first and second pusher plates are at the starting point, the first and second pusher plates are distributed in a stepped manner, with the lateral span being the smallest. The first and second pusher plates located in the same chamber can be reasonably distributed in the chamber, which increases the storage area of ​​the storage area without affecting the extrusion area. Furthermore, when a local pusher plate is damaged, it only needs to be replaced individually, reducing maintenance time and improving the maintenance efficiency of the equipment.

[0028] II. In this invention, the transition section is located between two adjacent protrusions. When the gear disk rotates, it drives the gear to rotate. When the gear meshes and rotates from the lowest point of the transition section along the highest point of the protrusion, the gear disk applies a forward squeezing force to the gear, thereby pushing the push plate forward. When the push plate moves forward, the second spring is compressed, and the push plate pushes the second push plate forward to slide, completing the squeezing. The distance from the highest point of the protrusion to the lowest point of the transition section is twice the thickness of the second push plate. Therefore, when the gear meshes with the highest point of the protrusion, the second push plate is just in contact with the grinding disc, ensuring that the feed mud in the storage area is fully squeezed out while effectively avoiding damage to the grinding disc due to overextension of the second push plate.

[0029] III. In this invention, the feeder's output port is located in the storage area. A stirring impeller mixes hot steam with crushed feed to form feed slurry. The feeder then transports the mixed feed slurry to the storage area. During the process of the pusher plate pushing the second pusher plate forward, when the push switch is completely separated from the second pusher plate, the push switch is in the pop-out state and controls the feeder to stop discharging slurry. During the process of the pusher plate pulling the second pusher plate backward, when the second pusher plate begins to press the push switch, the push switch is in the compressed state and controls the feeder to discharge slurry, thus achieving automatic feeding.

[0030] Fourth, in this invention, the number of cutting blades is the same as the number of storage areas, so as to achieve cutting as pressing.

[0031] V. In this invention, when excessive amounts of broken feed and dust accumulate in the dust collection frame in the flow pipe connected to the first blower, the sealing cap and pipe are pulled out, and the sealing cap is inserted into the flow pipe connected to the second blower. The pipe is then inserted into the flow pipe connected to the first blower, and the first and second blowers are controlled to rotate in opposite directions. At this time, the first blower draws in the air purified by the second blower and discharges it into the flow pipe connected to it. The guide block installed in the flow pipe is diamond-shaped. Through the cooperation of the guide plate and the guide block, the airflow direction is guided, so that the wind force blows away the broken feed and dust accumulated on the dust collection frame and discharges it into the pipe through the flow port. The pressurized pump sprays the broken feed and dust into the material conveyor. By changing the airflow direction, the flow pipe can be cleaned, while reducing the waste of raw materials.

[0032] VI. In this invention, when the first fan rotates in a forward direction, the air inlet for air intake draws air out of the flow pipe, creating a negative pressure inside the flow pipe. Air, broken feed, and dust from inside the casing are drawn into the flow pipe. The guide plate is located between two adjacent guide blocks and tilts along the direction of airflow, guiding the airflow onto the guide blocks. The dust collection frame increases the contact area with broken feed and dust. Gaps are left between multiple dust collection columns to collect broken feed and dust. The purified air is discharged from another air inlet, effectively reducing dust overflow.

[0033] VII. In this invention, the cut and shaped feed strips will have some broken feed and dust adhering to them. A stratosphere will be formed between the two air vents with mesh screens installed. When the feed strips are discharged from the outlet into the collection box, they will first pass through the stratosphere, which will blow away the broken feed and dust adhering to the feed strips, thus preventing the broken feed and dust from being scattered from the outlet.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] like Figure 1-13As shown, a mixed grass pellet feed pellet mill includes a machine body shell 1, a grinding disc 2, a mixer 3, a steam conveyor 4, a material conveyor 5, and a support body 6. The mixer 3, steam conveyor 4, and material conveyor 5 are fixedly connected to the support body 6. The machine body shell 1 is rotatably connected to the support body 6. The grinding disc 2 is fixedly connected to the mixer 3. The grinding disc 2 is circular and has an opening at one end. A shaping hole 7 is opened on the grinding disc 2. Multiple partitions 8 are fixedly connected to the inner wall of the grinding disc 2. The free ends of the multiple partitions 8 are fixedly connected to the same retaining ring 9. An arc is formed between two adjacent partitions 8 and the grinding disc 2. The chambers are all the same curvature. The first pusher plate 10 is slidably connected to the opposite sides of the partition wall 8. The first pusher plate 10 in the same chamber is slidably connected to the same second pusher plate 11. When the first pusher plate 10 and the second pusher plate 11 are at the starting point, the first pusher plate 10 and the second pusher plate 11 are distributed in a stepped manner. The first pusher plate 10, the second pusher plate 11 and the inner wall of the rolling disc 2 form a storage area 12. The side of the second pusher plate 11 away from the first pusher plate 10 is fixedly connected to a telescopic slide bar 13 and an extrusion structure. The telescopic end of the telescopic slide bar 13 is slidably connected to the partition wall 8.

[0051] The mixer 3 is equipped with a feed inlet 14. The output ports of the steam conveyor 4 and the material conveyor 5 are located above the feed inlet 14. The steam conveyor 4 continuously supplies hot steam to the feed inlet 14, and the material conveyor 5 continuously supplies processed crushed feed to the feed inlet 14. The feed is mixed into a feed slurry by the mixer 3. During the addition of crushed feed, dust in the crushed feed will overflow from the feed inlet 14. A circulating dust suppression structure is symmetrically installed on the support body 6 to absorb dust. The circulating dust suppression structure includes a flow pipe 15 and a guide block 16. The two ends of the flow pipe 15 are open. Multiple guide blocks 16 are provided and detachably installed on the flow pipe 15.

[0052] In order to fully squeeze the feed sludge in the storage area 12 out of the shaping hole 7, the first pusher plate 10 and the second pusher plate 11 are both arc-shaped on the side opposite to the rolling disc 2, and the arc surface is 1 / 3 of the arc surface inside the cavity. The thickness of the second pusher plate 11 is the same as that of the first pusher plate 10. A sliding groove 17 is provided on one side of the upper surface of the partition wall 8. The sliding groove 17 is slidably connected to the slider 18. The slider 18 is fixedly connected to the first pusher plate 10. The partition wall 8 is provided with a hole and a first spring 19 is fixedly connected in the hole. The other end of the first spring 19 is fixedly connected to the slider 18.

[0053] In this embodiment, when the extrusion structure extrudes the second pusher plate 11, the second pusher plate 11 will slide forward together with the first pusher plate 10. While the first pusher plate 10 slides forward, it will also slide along the direction of the partition wall 8 under the action of the slider 18. At this time, the first spring 19 is stretched. As the two first pusher plates 10 slide, the lateral span between the two first pusher plates 10 gradually increases, thereby increasing the extrusion area. Since the extrusion surfaces of the first pusher plate 10 and the second pusher plate 11 are both arc-shaped, and the arc surfaces are both 1 / 3 of the arc surface inside the cavity, when the two first pusher plates 10 are in contact with the grinding disc 2, the lateral span between the two first pusher plates 10 reaches the maximum. The second pusher plate 11 gradually passes through the space between the two first pusher plates 10 and is in contact with the grinding disc 2. At this time, the extrusion area reaches the maximum, which can fully extrude the feed sludge in the storage area 12. The feed sludge can be extruded in strip form through the set shaping hole 7.

[0054] When the second pusher plate 11 is pulled back, during the process of the second pusher plate 11 being pulled out from between the two first pusher plates 10, the first spring 19 returns to its original position and contracts, causing the slider 18 to slide backward, which in turn causes the first pusher plate 10 to slide backward. As the two first pusher plates 10 slide, the lateral span between the two first pusher plates 10 will gradually decrease. When the first pusher plate 10 and the second pusher plate 11 are at the starting point, the first pusher plate 10 and the second pusher plate 11 are distributed in a stepped manner, with the lateral span being the smallest. The first pusher plate 10 and the second pusher plate 11 located in the same chamber can be reasonably distributed in the cavity, which increases the storage area of ​​the storage area 12 without affecting the extrusion area. Furthermore, when a local pusher plate is damaged, it only needs to be replaced individually, reducing maintenance time and improving the maintenance efficiency of the equipment.

[0055] Example 2

[0056] like Figure 1-13 As shown, this embodiment has been improved on the basis of embodiment one as follows: Further, the side of the first pusher plate 10 is provided with an inclined surface 48, and the two opposite sides of the second pusher plate 11 have top blocks 49 that are adapted to the inclined surface 48. The top blocks 49 are slidably connected to the inclined surface 48. By setting the inclined surface 48 and the top blocks 49, feed sludge can be prevented from leaking out between the first pusher plate 10 and the second pusher plate 11.

[0057] The extrusion structure includes a rotary motor 20, a rotary spindle 21, a push plate 22, and a gear disk 23. The rotary motor 20 is fixedly connected in the outer casing 1 of the machine body, and the output shaft of the rotary motor 20 is detachably connected to the rotary spindle 21.

[0058] The rotating main shaft 21 is located at the center of the retaining ring 9 and is rotatably connected to the rolling disc 2;

[0059] The push plate 22 is T-shaped and vertical, passing through the retaining ring 9 and fixedly connected to the second push plate 11. The other end of the push plate 22 is fixedly connected to the support 24. The support 24 is rotatably connected to the gear 25. The support 24 is also fixedly connected to the second spring 26. The other end of the second spring 26 is fixedly connected to the retaining ring 9.

[0060] The gear disk 23 is fixedly connected to the rotating spindle 21 and meshes with the gear 25. The gear disk 23 includes multiple arc-shaped protrusions 27 and transition portions 28. The transition portion 28 is disposed between two adjacent protrusions 27, and the distance from the highest point of the protrusion 27 to the lowest point of the transition portion 28 is twice the thickness of the second push plate 11.

[0061] To ensure that the feed sludge in the storage area 12 is fully squeezed out, in this embodiment: the transition part 28 is set between two adjacent protrusions 27. When the gear disk 23 rotates, it drives the gear 25 to rotate. When the gear 25 meshes and rotates from the lowest point of the transition part 28 along the highest point of the protrusion 27, the gear disk 23 applies a forward squeezing force to the gear 25, thereby pushing the push plate 22 to move forward. When the push plate 22 moves forward, the second spring 26 is compressed, and the push plate 22 pushes the second push plate 11 to slide forward to complete the squeezing. The distance from the highest point of the protrusion 27 to the lowest point of the transition part 28 is twice the thickness of the second push plate 11. Therefore, when the gear 25 meshes with the highest point of the protrusion 27, the second push plate 11 is just in contact with the grinding disk 2, which ensures that the feed sludge in the storage area 12 is fully squeezed out while avoiding damage to the second push plate 11 due to excessive squeezing of the grinding disk 2.

[0062] When the gear 25 meshes and rotates from the highest point of the protrusion 27 along the lowest point of the transition 28, the second spring 26, which is in a compressed state, gradually returns to its original state, thereby driving the push plate 22 to move backward, and the push plate 22 pulls the second pusher plate 11 to slide backward.

[0063] Example 3

[0064] like Figure 1-13 As shown, this embodiment is improved on the basis of embodiment two as follows: Further, the mixer 3 is provided with a mixing impeller 29 and a feeder 30. The feed inlet 14 is located above the mixing impeller 29. Multiple feeders 30 are provided. Each feeder 30 corresponds to a storage area 12. The input port of the feeder 30 is connected to the inside of the mixer 3, and the output port is connected to the storage area 12. The feeder 30 is electrically connected to a push-button switch 31. The free end of the push-button switch 31 extends through the grinding disc 2.

[0065] The feeder 30 has its output port located in the storage area 12. When the first pusher plate 10 and the second pusher plate 11 are at the starting point, the second pusher plate 11 is located directly above the push switch 31, and the push switch 31 is in the pressed state. The feeder 30 has its output port located in front of the push switch 31.

[0066] The hot steam and crushed feed are mixed into feed slurry by the impeller 29. The mixed feed slurry is transported to the storage area 12 by the feeder 30. When the push plate 22 pushes the second push plate 11 forward, the push switch 31 is completely separated from the second push plate 11. At this time, the push switch 31 is in the pop-out state and controls the feeder 30 to stop discharging slurry.

[0067] As the push plate 22 pulls the second push plate 11 backward, when the second push plate 11 begins to press the push switch 31, the push switch 31 is in a compressed state and controls the feeder 30 to discharge mud, thus achieving automatic material feeding.

[0068] Furthermore, an outer sealing plate 32 is fixedly connected to the shaft of the rotating main shaft 21. The outer sealing plate 32 is rotatably connected to the open end of the crushing disc 2. Cutting blades 33 extend outward from the outer sealing plate 32. The number of cutting blades 33 is the same as the number of storage areas 12, so that cutting can be done as the material is pressed. The cutting blades 33 are slidably connected to the disc body of the crushing disc 2. During the rotation of the rotating main shaft 21, the outer sealing plate 32 will drive the cutting blades 33 to cut the feed strips.

[0069] Example 4

[0070] like Figure 1-13 As shown, this embodiment has been improved on the basis of embodiment one as follows: further, the guide block 16 is rhomboid in shape, and multiple baffles 34 are provided on the two adjacent long sides of the guide block 16. Each of the multiple baffles 34 is fitted with a dust collection frame 35, and several dust collection top columns 36 in the shape of spikes are fixedly connected to the dust collection frame 35.

[0071] Furthermore, multiple guide plates 37 are rotatably connected to the two opposing inner sidewalls of the flow tube 15, and the guide plates 37 are located between two adjacent guide blocks 16.

[0072] Furthermore, a first pair of interfaces 38 is provided on the side wall of the flow pipe 15 near the agitator 3. One of the first pair of interfaces 38 is connected to a sealing cap 39, and the other first pair of interfaces 38 is detachably connected to a pipe 40. The pipe 40 is adapted to the flow pipe 15 and its end abuts against the inner wall of the flow pipe 15. A flow port 41 is provided on one side of the pipe 40, and the flow port 41 is connected to the flow pipe 15. The pipe 40 can block the flow pipe 15, so that the material in the flow port 41 can only enter through the flow port 41. A pressure pump 42 is fixedly connected to the other end of the pipe 40, and the pressure pump 42 is connected to the material conveyor 5.

[0073] Furthermore, a first fan 44 and a second fan 47 are detachably installed on the two flow pipes 15 respectively. The first fan 44 and the second fan 47 are each provided with two air inlets. The air inlet of the first fan 44 is connected to the end of one of the flow pipes 15 away from the agitator 3, and a mesh 43 is installed on the other air inlet.

[0074] The air outlet of the second blower 47 is connected to the end of another flow pipe 15 away from the mixer 3. A mesh 43 is installed on the other air outlet to prevent feed strips from being sucked into the blower and causing blockage. The two air outlets with mesh 43 are opposite to each other.

[0075] Pipe 40 is located on the flow pipe 15, which is connected to the air outlet;

[0076] The sealing cap 39 is located on the flow pipe 15, which is connected to the air inlet.

[0077] Furthermore, a discharge port 45 is provided at the bottom of the outer casing 1. The discharge port 45 is located below the grinding disc 2. Two air vents with partitions 43 are located between the discharge port 45 and the grinding disc 2. After the feed strips are cut and shaped, some broken feed and dust will stick to them. A stratosphere will be formed between the two air vents with partitions 43. When the feed strips are discharged from the discharge port 45 into the collection box 46, they will first pass through the stratosphere, which will blow away the broken feed and dust sticking to the feed strips, preventing the broken feed and dust from being scattered from the discharge port 45. A collection box 46 is provided below the discharge port 45 to collect the feed strips. A rear cover 50 is rotatably connected to the side of the support body 6 away from the outer casing 1.

[0078] In this embodiment: when the first fan 44 rotates in a forward direction, the air inlet for air intake draws the air out of the flow pipe 15. At this time, a negative pressure is formed inside the flow pipe 15. The air, broken feed and dust inside the outer casing 1 are sucked into the flow pipe 15. The guide plate 37 is located between two adjacent guide blocks 16. The guide plate 37 is tilted along the direction of airflow, thereby guiding the airflow onto the guide block 16. The dust collection frame 35 can increase the contact area with broken feed and dust. There are gaps between the multiple dust collection top columns 36, which can collect broken feed and dust in the gaps. The purified air is discharged from another air inlet.

[0079] The second fan 47 rotates in the opposite manner to the first fan 44, blowing air into the flow pipe 15 connected to the second fan 47;

[0080] When excessive amounts of broken feed and dust accumulate in the dust collection frame 35 of the flow pipe 15 connected to the first blower 44, the sealing cap 39 and pipe 40 are removed, and the sealing cap 39 is inserted into the flow pipe 15 connected to the second blower 47; the pipe 40 is inserted into the flow pipe 15 connected to the first blower 44, and the first blower 44 and the second blower 47 are controlled to rotate in reverse. At this time, the first blower 44 drives the second blower 47... The purified air is drawn in and discharged into the connected flow pipe 15. The guide block 16 installed in the flow pipe 15 is diamond-shaped. Through the cooperation of the guide plate 37 and the guide block 16, the air direction is guided, so that the wind force blows away the broken feed and dust gathered on the dust collection frame 35 and discharges them into the pipe 40 through the flow port 41. The pressurized pump 42 sprays the broken feed and dust into the material conveyor 5. By changing the air direction, the flow pipe 15 can be cleaned, and the waste of raw materials can be reduced.

[0081] In summary, the workflow of this invention is as follows: chopped feed and hot steam are added to the mixer 3 through the steam conveyor 4 and the material conveyor 5. The hot steam and chopped feed are mixed into feed slurry by the rotation of the mixing impeller 29. The mixed feed slurry is then transported to the storage area 12 through the feeder 30.

[0082] When the gear disk 23 rotates, it drives the gear 25 to rotate. When the gear 25 meshes and rotates from the lowest point of the transition portion 28 along the highest point of the protrusion 27, the gear disk 23 applies a forward squeezing force to the gear 25, thereby pushing the push plate 22 forward. When the push plate 22 moves forward, the second spring 26 is compressed, and the push plate 22 pushes the second pusher plate 11 to slide forward. The second pusher plate 11 will slide forward together with the first pusher plate 10. While the first pusher plate 10 slides forward, it will also slide along the direction of the partition 8 due to the action of the slider 18. At this time, the first spring 19 is stretched. As the two first pusher plates 10 slide, the space between the two first pusher plates 10... The lateral span gradually increases, thereby increasing the extrusion area. Since the extrusion surfaces of the first pusher plate 10 and the second pusher plate 11 are both arc-shaped, and the arc surfaces are 1 / 3 of the arc surface inside the cavity, when the two first pusher plates 10 are in contact with the grinding disc 2, the lateral span between the two first pusher plates 10 reaches its maximum. The second pusher plate 11 gradually passes between the two first pusher plates 10 and is in contact with the grinding disc 2. At this time, the extrusion area reaches its maximum, which can fully extrude the feed mud in the storage area 12. The feed mud can be extruded in the form of strips through the set shaping holes 7. During the rotation of the rotating main shaft 21, the outer sealing disc 32 will drive the cutting blade 33 to cut the feed strips.

[0083] When gear 25 meshes and rotates from the highest point of protrusion 27 along the lowest point of transition 28, the second spring 26, which is in a compressed state, gradually returns to its original state, thereby driving push plate 22 to move backward. Push plate 22 pulls second push plate 11 to slide backward. When second push plate 11 is pulled back, during the process of second push plate 11 being pulled out from between the two first push plates 10, first spring 19 returns to its original state and contracts, driving slider 18 to slide backward, thereby causing first push plate 10 to slide backward. As the two first push plates 10 slide, the lateral span between the two first push plates 10 will gradually decrease. When the first push plate 10 and the second push plate 11 are at the starting point, the first push plate 10 and the second push plate 11 are distributed in a stepped manner.

[0084] The output port of the feeder 30 is located in the storage area 12. When the first pusher plate 10 and the second pusher plate 11 are at the starting point, the second pusher plate 11 is located directly above the push switch 31, and the push switch 31 is in the pressed state. The output port of the feeder 30 is located in front of the push switch 31.

[0085] As the pusher plate 22 pushes the second pusher plate 11 forward, when the pusher switch 31 is completely separated from the second pusher plate 11, the pusher switch 31 is in the pop-out state and controls the feeder 30 to stop discharging mud.

[0086] As the push plate 22 pulls the second push plate 11 to slide backward, when the second push plate 11 presses the push switch 31, the push switch 31 is in a compressed state and controls the feeder 30 to discharge mud.

[0087] When the first fan 44 rotates in a forward direction, the air inlet for air intake draws the air out of the flow pipe 15. At this time, a negative pressure is formed inside the flow pipe 15. The air, broken feed and dust inside the outer casing 1 are sucked into the flow pipe 15. The guide plate 37 is located between two adjacent guide blocks 16. The guide plate 37 is tilted along the direction of airflow, thereby guiding the airflow onto the guide block 16. The dust collection frame 35 can increase the contact area with broken feed and dust. There are gaps between the multiple dust collection top columns 36, which can collect broken feed and dust in the gaps. The purified air is discharged from another air inlet.

[0088] The second fan 47 rotates in the opposite manner to the first fan 44, blowing air into the flow pipe 15 connected to the second fan 47;

[0089] When excessive amounts of broken feed and dust accumulate in the dust collection frame 35 of the flow pipe 15 connected to the first blower 44, the sealing cap 39 and pipe 40 are pulled out, and the sealing cap 39 is inserted into the flow pipe 15 connected to the second blower 47. The pipe 40 is then inserted into the flow pipe 15 connected to the first blower 44. The first blower 44 and the second blower 47 are controlled to rotate in reverse. At this time, the first blower 44 draws in the air purified by the second blower 47 and discharges it into the flow pipe 15 connected to it. The guide block 16 installed in the flow pipe 15 is diamond-shaped. Through the cooperation of the guide plate 37 and the guide block 16, the airflow direction is guided, so that the wind force blows away the broken feed and dust accumulated on the dust collection frame 35 and discharges it into the pipe 40 through the flow port 41. The pressurized pump 42 sprays the broken feed and dust into the material conveyor 5.

[0090] After the feed strips are cut and shaped, some broken feed and dust will stick to them. A stratosphere will be formed between the two air vents with the mesh 43 installed. When the feed strips are discharged from the outlet 45 into the collection box 46, they will first pass through the stratosphere, which will blow away the broken feed and dust sticking to the feed strips.
