Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry feed production, and in particular to animal husbandry feed crushing equipment. Background Art

[0002] Feed mainly refers to the food of animals raised in agriculture or animal husbandry, including more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives. With the development and progress of the breeding industry, the use of feed products with higher economic value instead of raw grain to feed animals will gradually become the mainstream, and the pattern of small-scale farmers raising animals is also gradually changing. The proportion of large-scale and mechanized breeding structures has increased significantly in recent years. These changes will strongly drive the growth of demand for industrial feed.

[0003] Nowadays, there are various types of feed. Many feeds are prepared from raw materials such as grains. These feed raw materials need to be crushed when producing feed. Most of the current crushing devices only pour the feed raw materials into a processing box for crushing. During the crushing process, some feed will accumulate under the crushing knife, and all feed cannot be completely crushed, resulting in poor crushing effect. Moreover, the crushed feed in the processing box often accumulates at the bottom of the box, which is time-consuming and labor-intensive to take out, and the removal efficiency is poor.

[0004] In order to solve the above technical problems, a Chinese patent document (publication number CN114985066A) discloses an efficient crushing device for livestock feed production raw materials, including a crushing box, an upper end of the crushing box is provided with a material injection port, a lower end of the wide side inner wall of the crushing box is provided with a discharge port through the outside, and two horizontal plates arranged along the long side direction are provided above the interior of the crushing box, the two horizontal plates are arranged one above and one below, and the two ends of the upper horizontal plate are fixedly connected to the two sides of the inner wall of the crushing box respectively, and the two horizontal plates are arranged along the two sides of the wide side direction of the crushing box. A number of shear plates are fixedly connected to the side walls, and the shear plates are arranged linearly along the long side of the horizontal plate, and the opposite surfaces of the shear plates on the upper and lower sides abut against each other. A dual-axis motor is provided on the wide side wall of the crushing box away from the discharge port; a bottom plate is provided at the lower interior of the crushing box, and a U-shaped enclosure is fixedly connected to the upper surface of the bottom plate, with the open end of the U-shaped enclosure facing the discharge port, and a movable plate is provided at the upper inner end of the U-shaped enclosure, and the lower output shaft of the dual-axis motor drives the bottom plate to move up and down inside the crushing box through a gear assembly.

[0005] The above technical solution is driven by a dual-axis motor, so that the shear stress between the upper plurality of shear plates moving along the length direction breaks the feed, and the broken feed falls onto the movable plate on the bottom plate. Therefore, the feed in the above technical solution can only be broken between the upper plurality of shear plates and the lower plurality of shear plates and gradually accumulates on the movable plate; however, since the feed contains a large amount of water, part of the feed will adhere to the movable plate after the initial crushing, and at the same time, it will combine with other initially crushed feed to form agglomerates.

[0006] In addition, in the above technical solution, during the crushing process of the upper and lower shear plates, the moisture in the crushed feed will adhere to the plate surface of the shear plates, so that during the subsequent feed crushing process, part of the feed will adhere to the shear plates. This causes the shear stress between the upper and lower shear plates to be subjected to the resistance of the feed adhered to the shear plates, affecting the feed crushing effect. Summary of the Invention

[0007] The present invention is intended to provide a livestock feed crushing device to solve the technical problem in the prior art that due to the large amount of water in the feed, part of the feed will adhere to the movable plate in the prior art after initial crushing, and at the same time, it will combine with other initially crushed feed to form agglomerates.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a livestock feed crushing equipment, comprising a crushing box and a blower and a three-phase asynchronous motor arranged at both ends of the crushing box, the top and bottom of the crushing box are respectively provided with a feed port and a discharge port which are relatively positioned, the bottom of the crushing box is rotatably connected to a sealing cover for sealing the discharge port, the left end of the crushing box is provided with an air inlet, the air outlet of the blower is aligned with the air inlet, the right end of the crushing box is provided with a filtering mechanism for filtering smaller livestock feed, the filtering mechanism is sleeved on the circumference of the three-phase asynchronous motor, the output shaft of the three-phase asynchronous motor is coaxially connected to a spiral shaft, the spiral shaft extends along the axis direction of the crushing box toward the position of the air inlet, the spiral shaft is arranged along its axis direction, each spiral sheet is provided with an air vent, and a cutting mechanism for crushing livestock feed is provided between adjacent spiral sheets, and the cutting mechanism is fixed on the spiral shaft.

[0009] During use, the three-phase asynchronous motor and the blower are started, the three-phase asynchronous motor drives the spiral shaft in the crushing box to rotate, and the blower blows air into the crushing box through the air inlet corresponding to the air outlet; at this time, the livestock feed is put into the crushing box through the feed inlet, and when the livestock feed initially contacts the spiral blades, the spiral blades rotate as the spiral shaft rotates, so the edges of the spiral blades perform the initial cutting on the livestock feed, and part of the cut livestock feed will enter between adjacent spiral blades, and the remaining livestock feed will continue to be cut by the spiral blades until all the livestock feed enters between adjacent spiral blades; when the livestock feed enters between adjacent spiral blades, the cutting mechanism between the adjacent spiral blades crushes and cuts the livestock feed, and at the same time, since the cutting mechanism is fixed on the spiral shaft, the cutting mechanism rotates as the spiral shaft rotates, and during the rotation process, the livestock feed is pounded so that the livestock feed is formed into a required size.

[0010] When the livestock feed is cut, crushed and pounded, the blower blows air into the crushing box all the time, which accelerates the air flow in the crushing box and blows it onto the livestock feed through the vents on the spiral blades, thereby accelerating the evaporation of moisture on the surface of the livestock feed and preventing the livestock feed from clumping. Secondly, driven by the wind force generated by the blower, part of the livestock feed is blown toward the position of the filtering mechanism, and some livestock feed contains smaller-sized livestock feed. When passing through the filtering mechanism, the smaller-sized livestock feed will be discharged from the crushing box, leaving the larger-sized livestock feed in the crushing box for cutting, crushing and pounding. In this way, the wind force is used to perform the initial screening of livestock feed that meets the size requirements during the livestock feed crushing process.

[0011] After waiting for a period of time, the amount of smaller-sized livestock feed discharged and the state of the livestock feed at the feed inlet are used to determine whether the livestock feed is crushed to meet the size requirements. If it meets the crushing size requirements, the three-phase asynchronous motor and the blower are turned off, and the sealing cover is opened to expose the discharge port, so that all the livestock feed is discharged from the discharge port.

[0012] Furthermore, the filtering mechanism includes a filter plate surrounding the input end of the three-phase asynchronous motor. The filter plate has an annular structure, and the plate surface of the filter plate is evenly distributed with several filter holes along its circumferential direction. One side of the filter plate faces the inside of the crushing box, and the other side is detachably connected to a storage box for storing smaller livestock feed. The storage box has an annular structure as a whole.

[0013] This solution uses a filter plate to filter smaller livestock feed, which passes through the filter holes of the filter plate into a storage box. The storage box is used to store the smaller livestock feed, so that livestock feed that meets size requirements can be collected during the livestock feed crushing process.

[0014] Furthermore, the cutting mechanism includes a protruding block fixed on the spiral shaft, a telescopic rod extending in the radial direction is fixed to the end of the protruding block away from the spiral shaft, and a spike-shaped cutting blade is welded to the end of the telescopic rod away from the protruding block.

[0015] The raised block provided in this scheme is used to connect the spiral shaft and the telescopic rod. During the rotation of the spiral shaft, the spiral shaft generates centrifugal force, causing the telescopic rod driven to rotate to extend in the radial direction due to its centrifugal force. When the telescopic rod extends, the cutting blade at the end of the telescopic rod will perform preliminary cutting on the livestock feed; at the same time, the telescopic rod will also pound the livestock feed as the spiral shaft rotates.

[0016] Furthermore, the cutting mechanism also includes an arc-shaped crushing blade, which includes an arc surface and a straight surface. The straight surface is welded to the side where the telescopic rod and the raised block are connected, and the arc surface faces the feed port of the crushing box.

[0017] In this solution, the straight surface of the crushing blade is welded to the side where the telescopic rod and the raised block are connected, which can strengthen the connection stability between the telescopic rod and the raised block; secondly, the arcuate surface of the crushing blade faces the feed inlet of the crushing box. Therefore, when the spiral blade rotates to transport livestock feed, the crushing blade will cut and crush the livestock feed moving along the axial direction.

[0018] Furthermore, a plurality of spike blades are evenly distributed along the circumference of the inner wall of the crushing box. The spike blades face between adjacent spiral sheets and are staggered with the positions of the cutting blades.

[0019] The spiked blades and the cutting blades in this solution are staggered in position, so that when the spiral blade drives the livestock feed to rotate, the spiked blades cut the livestock feed while cooperating with the cutting blades to achieve shearing from both sides of the livestock feed, thereby improving the livestock feed crushing efficiency.

[0020] Furthermore, a ventilation plate is provided on the crushing box at the air inlet position, and a concave hole communicating with the air inlet is provided in the middle of the ventilation plate, and the concave hole is inclined outward toward the side of the spiral shaft to form a ventilation hole.

[0021] In this solution, the air path blown by the blower into the crushing box is redirected through the concave holes on the ventilation plate, and the ventilation openings formed by the outward-inclined concave holes are used to concentrate all wind force at the position of the spiral shaft, so that the maximum wind force can be used to dry the moisture on the surface of the livestock feed.

[0022] Furthermore, the device includes a mounting box located in the middle of the storage box, the end of which is welded to the end of the crushing box. The three-phase asynchronous motor is embedded in the mounting box, and the output shaft of the three-phase asynchronous motor passes through the mounting box and the crushing box in sequence and is coaxially connected to the screw shaft. The mounting box is provided to protect the three-phase asynchronous motor.

[0023] Furthermore, a support base for supporting the blower is provided at the bottom of the blower. The support base is not only used to support the blower, but also has the function of raising the height of the blower so that the air outlet of the blower corresponds to the air inlet of the crushing box.

[0024] Compared with the prior art, the present invention also has the following technical effects:

[0025] 1. The present invention utilizes the edge of the spiral blade to perform preliminary cutting on the livestock feed, utilizes the retractable cutting blade to perform internal cutting on the clumped livestock feed, utilizes the cutting blade and the spike blade to stagger and shear the livestock feed to achieve radial cutting of the livestock feed, utilizes the crushing blade to achieve axial cutting of the livestock feed, and simultaneously utilizes the telescopic rod, cutting blade and crushing blade that rotate with the spiral shaft to pound the livestock feed, so that the livestock feed of the present invention can quickly complete the crushing operation, thereby improving the efficiency of the livestock feed crushing process.

[0026] 2. The present invention changes the existing feed pneumatic conveying device which only has a simple feed conveying function. On the basis of completing the pneumatic conveying, the crushed livestock feed can be actively screened, so that the livestock feed can be directly stored and collected after being conveyed and discharged, avoiding the trouble of separate screening after transportation, integrating the processing technology, and improving the overall efficiency of livestock feed production and processing; at the same time, the wind power is used to accelerate the evaporation of moisture on the surface of the livestock feed, and at the same time, the livestock feed is prevented from adhering to the inner wall of the crushing box. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 This is a structural schematic diagram of an animal feed crushing device of the present invention. DETAILED DESCRIPTION

[0028] The following is further described in detail through specific implementation methods:

[0029] The figure marks in the drawings of the specification include: crushing box 1, feed hopper 2, installation box 3, storage box 4, filter plate 5, filter hole 6, three-phase asynchronous motor 7, sealing cover 8, closing plate 9, spiral shaft 10, raised block 11, spiral sheet 12, telescopic rod 13, cutting blade 14, crushing blade 15, vent 16, vent plate 17, vent 18, support base 19, blower 20, spiked blade 21.

[0030] This embodiment provides a livestock feed pulverizing device, comprising a pulverizing box 1, a blower 20 and a three-phase asynchronous motor 7 disposed at both ends of the pulverizing box 1, and a support base 19 disposed at the bottom of the blower 20 for supporting the blower 20. The support base 19 is configured to elevate the blower 20 so that the air outlet of the blower 20 corresponds to the air inlet of the pulverizing box 1.

[0031] The machine also includes a mounting box 3 located in the middle of the material storage box 4. The end of the mounting box 3 is welded to the end of the crushing box 1. The three-phase asynchronous motor 7 is embedded in the mounting box 3. The output shaft of the three-phase asynchronous motor 7 passes through the mounting box 3 and the crushing box 1 in sequence and is coaxially connected to the screw shaft 10. The mounting box 3 is provided to protect the three-phase asynchronous motor 7.

[0032] The top and bottom of the crushing box 1 are respectively provided with a feed port and a discharge port which are relatively positioned. The bottom of the crushing box 1 is rotatably connected to a sealing cover 8 for sealing the discharge port. An air inlet is provided at the left end of the crushing box 1, and the air outlet of the blower 20 is aligned with the air inlet. The right end of the crushing box 1 is provided with a filtering mechanism for filtering smaller livestock feed. The filtering mechanism is sleeved on the side of the three-phase asynchronous motor 7. A spiral shaft 10 is coaxially connected to the output shaft of the three-phase asynchronous motor 7. The spiral shaft 10 extends along the axial direction of the crushing box 1 toward the position of the air inlet. Several spiral spiral blades 12 are arranged on the spiral shaft 10 along its axial direction. Each spiral blade 12 is provided with an air vent 16. A cutting mechanism for crushing livestock feed is provided between adjacent spiral blades 12, and the cutting mechanism is fixed on the spiral shaft 10.

[0033] When in use, the three-phase asynchronous motor 7 and the blower 20 are started, the three-phase asynchronous motor 7 drives the spiral shaft 10 in the crushing box 1 to rotate, and the blower 20 blows air into the crushing box 1 through the air inlet corresponding to the air outlet; at this time, livestock feed is put into the crushing box 1 through the feed inlet, and when the livestock feed initially contacts the spiral blades 12, the spiral blades 12 rotate as the spiral shaft 10 rotates, so the edges of the spiral blades 12 perform an initial cutting on the livestock feed, and part of the cut livestock feed will enter between adjacent spiral blades 12, and the remaining livestock feed will continue to be cut by the spiral blades 12 until all the livestock feed enters between adjacent spiral blades 12; when the livestock feed enters between adjacent spiral blades 12, the cutting mechanism between the adjacent spiral blades 12 crushes and cuts the livestock feed, and at the same time, since the cutting mechanism is fixed on the spiral shaft 10, the cutting mechanism rotates as the spiral shaft 10 rotates, and during the rotation process, the livestock feed is pounded so that the livestock feed is formed into a required size.

[0034] The cutting mechanism includes a raised block 11 fixed to the screw shaft 10. A radially extending telescopic rod 13 is fixed to the end of the raised block 11 away from the screw shaft 10. A spike-shaped cutting blade 14 is welded to the end of the telescopic rod 13 away from the raised block 11. The raised block 11 is used to connect the screw shaft 10 and the telescopic rod 13. During the rotation of the screw shaft 10, the screw shaft 10 generates centrifugal force, causing the rotating telescopic rod 13 to extend radially due to the centrifugal force. As the telescopic rod 13 extends, the cutting blade 14 at the end of the telescopic rod 13 performs a preliminary cut on the livestock feed. At the same time, the telescopic rod 13 also beats the livestock feed as it rotates with the screw shaft 10.

[0035] Preferably, the cutting mechanism further includes an arc-shaped crushing blade 15, which includes an arcuate surface and a linear surface. The linear surface is welded to the side where the telescopic rod 13 and the raised block 11 meet, with the arcuate surface facing the feed inlet of the crushing box 1. The linear surface of the crushing blade 15 is welded to the side where the telescopic rod 13 and the raised block 11 meet, thereby strengthening the connection stability between the telescopic rod 13 and the raised block 11. Furthermore, the arcuate surface of the crushing blade 15 faces the feed inlet of the crushing box 1. Therefore, as the spiral blade 12 rotates to transport livestock feed, the crushing blade 15 cuts and crushes the livestock feed moving axially.

[0036] At the same time, a number of spiked blades 21 are evenly distributed along the circumference of the inner wall of the crushing box 1. The spiked blades 21 face between adjacent spiral blades 12 and are staggered with the cutting blades 14. The staggered arrangement of the spiked blades 21 and the cutting blades 14 allows the spiked blades 21 to cut the feed while cooperating with the cutting blades 14 to shear the feed from both sides, thereby improving the efficiency of feed crushing.

[0037] In this solution, when cutting, crushing and pounding the livestock feed, the blower 20 continuously blows air into the crushing box 1, thereby accelerating the air flow in the crushing box 1 and blowing the air onto the livestock feed through the vents 16 on the spiral blades 12, thereby accelerating the evaporation of moisture on the surface of the livestock feed. Secondly, driven by the wind force generated by the blower 20, part of the livestock feed is blown toward the position of the filtering mechanism, and part of the livestock feed contains smaller-sized livestock feed. When passing through the filtering mechanism, the smaller-sized livestock feed will be discharged from the crushing box 1, allowing the larger-sized livestock feed to remain in the crushing box 1 for cutting, crushing and pounding. In this way, the wind force is used to perform the initial screening of livestock feed that meets the size requirements during the livestock feed crushing process.

[0038] The filtering mechanism includes a ring-shaped filter plate 5 surrounding the input terminal of a three-phase asynchronous motor 7. The filter plate 5 has a plurality of filter holes 6 distributed evenly along its circumference. One side of the filter plate 5 faces the interior of the crushing box 1, and the other side is detachably connected to a storage bin 4 for storing smaller livestock feed. The storage bin 4 has an overall ring-shaped structure. The filter plate 5 is used to filter smaller livestock feed, which then passes through the filter holes 6 of the filter plate 5 into the storage bin 4. The storage bin 4 is used to store the smaller livestock feed, allowing the collection of livestock feed that meets size requirements during the crushing process.

[0039] Preferably, a ventilation plate 17 is provided on the crushing box 1 at the air inlet position, and a concave hole communicating with the air inlet is opened in the middle of the ventilation plate 17. The concave hole is inclined outward toward the side of the spiral shaft 10 to form a ventilation hole 18.

[0040] In this solution, the air path blown by the blower 20 into the crushing box 1 is redirected through the concave holes on the ventilation plate 17, and the vents 18 formed by the outward-inclined concave holes are used to concentrate all wind forces at the position of the spiral shaft 10, so that the maximum wind force can be used to dry the moisture on the surface of the livestock feed.

[0041] After waiting for a period of time, the amount of smaller-sized livestock feed discharged and the state of the livestock feed at the feed inlet are used to determine whether the livestock feed is crushed to meet the size requirements. If the crushing size requirements are met, the three-phase asynchronous motor 7 and the blower 20 are turned off, and the sealing cover 8 is opened to expose the discharge port, so that all the livestock feed is discharged from the discharge port.

[0042] The above are only embodiments of the present invention, and common knowledge such as the specific technical solutions and / or characteristics in the solutions are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
