Description

Technical Field

[0001] The present invention belongs to the technical field of feed processing, and specifically relates to a high-efficiency feed pulverizing device for feed processing. Background Art

[0002] Feed pulverization is a key link in the feed processing process. Its core goal is to break raw materials (such as grains, soybean meal, straw, fish meal, etc.) into appropriate particle sizes to meet the nutritional absorption needs of different breeding objects (such as livestock, poultry, aquatic products, pets, etc.), and at the same time optimize the efficiency of subsequent mixing, granulation and other processes. Specific requirements include: particle size uniformity: different feed formulations have strict requirements for the particle size of raw materials (for example, piglet feed needs to be pulverized finer to improve digestibility, and aquatic feed needs to avoid excessive particle coarseness resulting in sinking waste); processing efficiency: large-scale feed production requires the pulverizing device to have a high throughput to match the rhythm of the assembly line operation; energy consumption and cost: the energy consumption in the pulverization process accounts for more than 30% of the total energy consumption in feed processing. Reducing unit energy consumption is an important goal in the industry; multi-functional adaptability: it needs to be compatible with a variety of raw materials (such as high-fiber straw, high-oil raw materials, heat-sensitive components, etc.) to avoid nutrient loss during the pulverization process.

[0003] A patent with the Chinese invention patent publication number CN115999692 discloses a feed processing and pulverizing device, which relates to the technical field of feed processing. The present invention includes a grinding box and a granulating box; a grinding device is installed in the grinding box; the grinding device includes a first stirring rod and a second stirring rod that are mutually connected; the top plate of the granulating box is provided with an upper hydraulic cylinder; a tablet pressing fixture is arranged in the middle of the granulating box; a lower hydraulic cylinder is arranged on the bottom plate of the granulating box; the output end of the upper hydraulic cylinder passes through the granulating box and is fixedly connected with a Y-shaped bracket; one end of each bifurcated wall of the Y-shaped bracket is fixedly provided with a pressing plate; the pressing plate is a semi-circular plate; a number of pressing heads are evenly arranged on the surface of the pressing plate; the output end of the lower hydraulic cylinder is fixedly connected with another pressing plate. In the present invention, the first stirring rod is movably connected to the second stirring rod through a rotating shaft and a shaft hole, and the grinding rollers on the first shaft rod and the second shaft rod are driven to rotate synchronously by an eccentric motor to realize the grinding and pulverization of the feed, prevent incomplete mixing of various feeds, and improve the quality of the feed.

[0004] However, the above technologies often have the following defects: For the roller pulverization technology, which relies on the principle of roller extrusion, it has high-efficiency pulverization ability for hard raw materials such as corn and soybean meal. However, when processing high-moisture raw materials such as fresh forage and distillers' grains, due to the high viscosity of the materials, they are easily attached to the roller surface to form the phenomenon of sticking rollers, resulting in a sharp drop in pulverization efficiency or even equipment shutdown. At the same time, limited by the physical characteristics of the extrusion pulverization mechanism, the technology has insufficient ability to finely control the particle size of the materials, especially difficult to meet the requirements in the field of aquatic feed, resulting in poor uniformity of the finished product particles and affecting the feeding efficiency of aquatic animals and the sedimentation stability of the feed.

[0005] To this end, the present invention provides a high-efficiency feed pulverizing device for feed processing. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A high-efficiency feed pulverizing device for feed processing according to the present invention includes a support plate. A hollow groove is provided in the middle of the upper surface of the support plate. The inner arc surface of the support plate is threadedly connected to a bottom basin. A bent edge is provided at the bottom of the outer arc surface of the bottom basin. A conical sleeve is movably sleeved on the outer arc surface of the bottom basin. An inner conical end is provided on the upper surface of the conical sleeve. A pulverizing chamber is provided in the middle of the outer arc surface of the conical sleeve. The top bent edge of the bottom basin abuts against the bottom of the inner arc surface of the conical sleeve. A pulverizing disc is sleeved in the middle pulverizing chamber of the conical sleeve. An annular serrated edge is provided at the edge of the upper surface of the pulverizing disc. A plurality of serrated ends are provided on the inner arc surface of the annular serrated edge. A through hole is provided on the upper surface of the pulverizing disc. The pulverizing disc is movably connected to a pulverizing blade through the through hole at the top. A blade part is provided on the outer arc surface of the pulverizing blade. A coupling part is provided at the bottom of the pulverizing disc near the blade part. A grinding sheet part is provided on the lower surface of the pulverizing blade.

[0008] One end of the shaft rod is fixedly installed with a chopping blade. One end of the chopping blade is placed in the middle of the inner conical end. The chopping blade is placed on the top of the annular serrated edge.

[0009] A flow collecting cover is fixedly installed on the upper surface of the inner conical end through bolts. An inner conical opening is provided in the middle of the upper surface of the flow collecting cover. The inner conical opening is in the same plane as the pulverizing chamber.

[0010] The bottom end of the shaft rod penetrates and is connected to the middle of the bottom basin. Fine teeth are provided on the outer arc surface of the shaft rod near the outer arc surface of the bottom basin. An inclined surface is provided at one end of the outer arc surface of the fine teeth.

[0011] Holes are provided on the upper surface of the pulverizing disc. The holes are placed on the top of the fine teeth. An annular gear is fixedly installed on the outer arc surface of the bottom basin. A driving gear is meshed with the serrated part on the outer arc surface of the annular gear.

[0012] A limiting bracket is sleeved on one side of the outer arc surface of the bottom basin away from the support plate. A stop ring is provided in the middle of the upper surface of the limiting bracket. The inner arc surface of the stop ring abuts against the surface of the bottom basin.

[0013] The bottom basin is fixedly installed with a motor through the shaft rod in the middle. The upper surface of the motor is fixedly installed on the limiting bracket.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The processing time is shortened through multi-stage crushing paths. The shredding blades located above the crushing disk rotate at high speed to form a horizontal shear surface, quickly cutting the long fiber raw materials into small segments. At the same time, the block raw materials are split and crushed to initially reduce the particle size of the raw materials. The high-speed rotation of the blade part and the grinding sheet part at the bottom of the crushing disk performs impact crushing and high-frequency grinding on the pre-crushed raw materials. The blade part crushes the hard particles, and the grinding sheet part refines the fiber materials. The synergistic effect of the two enables the raw materials to complete the whole process from "coarse crushing" to "ultra-fine crushing" in a short time, which improves the efficiency and uniformity compared with the traditional roller crushing.

[0016] 2. A dynamically adjustable crushing gap is formed by the beveled surface of the fine crushing teeth and the bottom surface of the bottom basin. When the particles fall into the bottom basin through the holes, they are thrown to the edge of the tooth group at high speed under the centrifugal force of the crushing disk driven by the shaft. The inclination angle of the beveled surface causes the particles to generate a combined effect of tangential sliding force and normal impact force when they contact the tooth surface. The fine crushing ability improves the quality of the finished feed. The coaxiality of the fine crushing teeth and the crushing disk eliminates the transmission energy loss of the traditional multi-axis system, and the relative movement of the driving gear and the ring gear forms a cycle of rebound and then collision, avoiding the ineffective cycle of large particles enveloping small particles.

Detailed implementation manners

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0026] As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the embodiment of the present invention includes a support plate 1. A hollow groove is provided in the middle of the upper surface of the support plate 1. The inner arc surface of the support plate 1 is threadedly connected with a bottom basin 2. A bent edge 21 is provided at the bottom of the outer arc surface of the bottom basin 2. A conical sleeve 3 is movably sleeved on the outer arc surface of the bottom basin 2. An inner conical end 31 is provided on the upper surface of the conical sleeve 3. A crushing chamber 32 is provided in the middle of the outer arc surface of the conical sleeve 3. The top bent edge 21 of the bottom basin 2 abuts against the bottom of the inner arc surface of the conical sleeve 3. A crushing disc 4 is sleeved in the middle crushing chamber 32 of the conical sleeve 3. An annular sawtooth edge 41 is provided at the edge of the upper surface of the crushing disc 4. A plurality of sawtooth ends are provided on the inner arc surface of the annular sawtooth edge 41. A through hole is provided on the upper surface of the crushing disc 4. The crushing disc 4 is movably connected with a crushing blade 42 through the through hole at the top. A blade part 43 is provided on the outer arc surface of the crushing blade 42. A coupling part 44 is provided at the bottom of the crushing disc 4 close to the blade part 43. A grinding sheet part 45 is provided on the lower surface of the crushing blade 42. One end of a shaft rod 5 is fixedly installed with a chopping blade 6. One end of the chopping blade 6 is placed in the middle of the inner conical end 31. The chopping blade 6 is placed on the top of the annular sawtooth edge 41. A flow collecting cover 7 is fixedly installed on the upper surface of the inner conical end 31 through a bolt. An inner conical opening 71 is provided in the middle of the upper surface of the flow collecting cover 7. The inner conical opening 71 is in the same plane as the crushing chamber 32.

[0027] The top of the entire device can be placed at the edge of the feed transport, so that when the transported feed is transported to the edge, it loses its bearing capacity and flows into the interior of the conical sleeve 3 from the top collector 7 along the oblique edge of the inner cone 71 due to the action of gravity. At the same time, the motor 12 at the bottom of the limit bracket 11 is started, and the shaft 5 starts to rotate when driven by the motor 12. It should be noted that the conical sleeve 3 is fixedly installed on the top of the entire motor 12 through the support plate 1. Since the middle section of the conical sleeve 3 is provided with a crushing chamber 32, and a crushing disk 4 is provided inside the crushing chamber 32, the crushing disk 4 The bottom surface of the bottom basin 2 is in contact with the top bent edge 21 of the bottom basin 2, and the shaft 5 penetrates the surface of the crushing disk 4 and the bottom basin 2. When the feed falls from the inner cone 71 to the bottom basin 2, the larger particles are retained on the upper surface of the bottom basin 2 because they cannot pass through the hole 46. At this time, the motor 12 drives the shaft 5 to rotate at a high speed, driving the crushing disk 4 and the top shredder blade 6 to rotate synchronously. The shredder blade 6 is located directly above the crushing disk 4, and its cutting edge forms a shear gap of 3-5mm with the upper surface of the crushing disk 4. When the feed particles fall, they are first chopped at high speed by the shredder blade 6, and the long stems of the fiber raw materials are cut into small sections. At the same time, The blocky raw materials are initially crushed. The annular serrated edge 41 on the edge of the crushing disk 4 and the bent edge 21 on the top of the bottom basin 2 form an interlaced grinding structure. When the falling feed particles are thrown to the edge by the rotating crushing disk 4, they are repeatedly squeezed and cut by the tooth patterns of the serrated edge 41 and the bent edge 21, realizing the pre-processing of "coarse crushing to screening". The particles with a particle size smaller than the sawtooth gap initially pass through the gap and enter the crushing chamber 32, while the larger particles are intercepted and continued to be crushed. The blade portion 43 (thickness 2-3mm, blade angle 30°-45°) of the crushing blade 42 is responsible for impact crushing the particles. Its linear speed can The grinding sheet 45 adjacent to the blade portion 43 is coated with tungsten carbide. The eddy current generated by high-speed rotation adsorbs the particles to the grinding surface, and high-frequency friction crushing is performed to further refine the particle size of the material. The diameter of the hole 46 of the bottom basin 2 can be flexibly adjusted by replacing the sieve plates with different apertures. The larger particles that do not pass through the hole 46 are brought to the upper part of the crushing chamber 32 as the crushing disk 4 rotates, and are mixed with the newly fallen feed and undergo the chopping, impact and grinding process again until the target particle size is reached. The arc surface arranged on the inner wall of the crushing chamber 32 can guide the material to move toward the hole 46 to avoid dead corners.

[0028] During this process, the shredding blade 6 and the crushing blade 42 form a three-dimensional crushing space with upper cutting and lower grinding, and cooperate with the pre-screening function of the annular serrated edge to complete multi-stage crushing of the feed particles. Compared with traditional roller crushing, the efficiency is improved and the energy consumption is reduced. At the same time, by adjusting the rotation speed of the shaft 5 and the screening aperture, the particle size distribution of the finished product can be accurately controlled to meet the diverse needs from livestock and poultry feed to aquatic microparticle feed.

[0029] The processing time is shortened through a multi-stage crushing path. The chopping blade 6 located above the crushing disc 4 rotates at a high speed to form a horizontal shear plane, quickly cutting the long fiber raw material into small segments. At the same time, the massive raw material is split and broken, initially reducing the particle size of the raw material. The high-speed rotation of the blade part 43 and the grinding piece part 45 at the bottom of the crushing disc 4 performs impact crushing and high-frequency grinding on the pre-crushed raw material. The blade part 43 shatters hard particles, and the grinding piece part 45 refines fiber-like materials. The synergistic effect of the two enables the raw material to complete the whole process from "coarse crushing" to "ultrafine crushing" in a short time, improving the efficiency and uniformity compared with traditional roller crushing.

[0030] As Figure 1 and Figure 4 shown, the bottom end of the shaft rod 5 runs through and is connected to the middle of the bottom basin 2. The outer arc surface of the shaft rod 5 is provided with fine crushing teeth 8 near the outer arc surface of the bottom basin 2. One end of the outer arc surface of the fine crushing teeth 8 is provided with an inclined plane 81. A hole 46 is opened on the upper surface of the crushing disc 4, and the hole 46 is placed on the top of the fine crushing teeth 8. The outer arc surface of the bottom basin 2 is fixedly installed with an annular gear 9. The serrated part of the outer arc surface of the annular gear 9 is meshed with a driving gear 10. A limiting bracket 11 is sleeved on the side of the outer arc surface of the bottom basin 2 away from the support plate 1. The middle of the upper surface of the limiting bracket 11 is provided with a stop ring 111, and the inner arc surface of the stop ring 111 abuts against the surface of the bottom basin 2. The bottom basin 2 is fixedly installed with a motor 12 through the shaft rod 5 in the middle, and the upper surface of the motor 12 is fixedly installed on the limiting bracket 11.

[0031] At the same time, the feed particles screened by the hole 46 fall into the inner bottom wall of the bottom basin 2 and contact the fine crushing teeth 8 with an inclination angle. The fine crushing teeth 8 are distributed in a conical array. The inclined plane 81 of the fine crushing teeth 8 forms a grinding gap of 1-2 mm with the bottom surface of the crushing disc 4. The particles are thrown towards the inner wall of the bottom basin 2 under the action of centrifugal force. First, they are intercepted by the inclined plane 81 of the fine crushing teeth 8. The relative movement between the inclined plane 81 and the bottom basin 2 generates a shear force to cut the particle size of the feed into 0.5-1 mm crushed particles. At the same time, the guiding action of the inclined plane 81 makes the particles enter the tooth gap along the tangential direction and receive high-frequency impact, further achieving the purpose of efficient crushing.

[0032] A dynamically adjustable crushing gap is formed between the inclined plane 81 of the fine crushing teeth 8 and the inner bottom surface of the bottom basin 2. When the particles fall into the bottom basin 2 through the hole 46, under the centrifugal force of the crushing disc 4 driven by the shaft rod 5, they are thrown towards the edge of the tooth group at a high speed. The inclination angle of the inclined plane 81 causes the particles to generate a combined action of tangential sliding force and normal impact force when contacting the tooth surface, improving the quality of the feed finished product with the refined crushing ability. And the coaxial arrangement of the fine crushing teeth 8 and the crushing disc 4 eliminates the transmission energy consumption loss of the traditional multi-axis system.

[0033] Secondly, when the driving gear 10 drives the annular tooth 9 to rotate counterclockwise through the reducer, the bottom basin 2 rotates counterclockwise synchronously, forming a relative motion with the crushing disk 4 driven by the shaft 5. The air flow vortex generated by the relative motion repeatedly throws the particles to the tooth surface, forming a cycle of impact, rebound and then impact. For example, when processing corn, the average number of impacts of the particles in the annular area increases, avoiding the ineffective cycle of large particles entraining small particles.
