Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to feed processing, and in particular relates to a splash-proof feed raw material crushing device. Background Art
[0002] Feed raw materials refer to feeds derived from animals, plants, microorganisms, or minerals during feed processing. They are substances derived from animals, plants, microorganisms, or minerals that are used in feed production but are not considered feed additives. Plants are the majority of feed ingredients, and regardless of the feed raw material, most require pulverization before mixing, pelleting, and other processes. However, the actual pulverization of feed raw materials still has the following drawbacks:
[0003] 1. During the crushing process of feed raw materials, whether they are large or small pieces, they need to be crushed in the end. However, during the crushing process, material splashing will often occur, and a large amount of debris will splash to the outside, causing both raw material loss and increased costs.
[0004] 2. Secondly, most feed raw materials cannot be completely crushed in one go, so they need to be crushed multiple times. However, the current crushing equipment lacks the function of realizing multi-stage crushing.
[0005] 3. Finally, the final crushing is mostly done by the rotary crushing of the cutting knife. During this process, it usually takes a certain amount of processing time to crush completely. However, the conventional raw material dropping process makes it difficult to keep the raw materials near the cutting knife, resulting in a short cutting and crushing time and ineffective crushing. Utility Model Content
[0006] The purpose of the utility model is to provide a splash-proof feed raw material crushing equipment. By arranging a dustproof plate, a crushing box, a crushing roller, a crushing shaft, a cover plate, a crushing chamber, and a crushing chamber, the utility model solves the problems of splashing when the feed raw materials are crushed, which easily leads to raw material loss and increased costs; lacks a multi-stage crushing processing function, and the raw materials fall too quickly during crushing, resulting in a short contact time with the cutting knife and low crushing efficiency.
[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0008] The utility model is a splash-proof feed raw material crushing equipment, comprising a crushing box, a lower hopper, a cover plate, a feed hopper, a crushing roller, a crushing shaft and a dust-proof plate, a crushing chamber is provided in the crushing box, two crushing rollers are rotatably connected on the two inner end walls of the crushing box in the crushing chamber, and equidistantly distributed sharp teeth are fixed on the outer periphery of the crushing rollers, a crushing chamber is provided in the crushing box below the crushing chamber, and a crushing shaft is rotatably connected on the two inner end walls of the crushing box in the crushing chamber, and equidistantly distributed crushing knives are fixed on the outer periphery of the crushing shaft, a lower hopper is fixed to the bottom end of the crushing box, a cover plate is fixed to the top of the crushing box, and two symmetrical feeding ports are provided on the top of the crushing box below the cover plate, a feeding hopper is fixed outside each of the feeding ports, and a dust-proof plate is rotatably connected to the top of the crushing box in the feeding port.
[0009] Furthermore, two symmetrical base plates 1 are fixed in the crushing box outside the crushing cavity, the opposite surfaces of the two base plates 1 are arc-shaped and surround the crushing cavity, and the upper surfaces of the two base plates 1 are inclined surfaces.
[0010] Furthermore, shafts are fixed on both ends of the top of the dustproof plate, and the shafts are rotatably connected to the end walls of the crushing box. The top of the dustproof plate contacts the bottom surface of the cover plate, and the bottom of the dustproof plate contacts the upper inclined surface of the base plate.
[0011] Furthermore, two symmetrical substrates 2 are fixed in the crushing box outside the crushing chamber, and the opposite surfaces of the two substrates 2 are both arc surfaces and surround the crushing chamber. The gap between the two upper ends of the substrates 2 is set as a feed slot, and the gap between the two lower ends of the substrates 2 is set as a discharge slot, and the size of the discharge slot is smaller than the size of the feed slot. The crushing chamber is connected to the crushing chamber through the feed slot.
[0012] Furthermore, motor 1 and motor 2 are fixed to the outside of one end of the crushing box, and the output shaft of motor 1 is connected to the end of a crushing roller. Gears are fixed to the ends of the two crushing rollers away from motor 1, and the two gears are meshed with each other.
[0013] Furthermore, the output shaft of the second motor is connected to the end of the crushing shaft.
[0014] Furthermore, symmetrically distributed legs are fixed on both outer side walls of the crushing box, the upper end of the lower hopper is connected to the interior of the crushing box, and the bottom end of the lower hopper is an open structure.
[0015] The utility model has the following beneficial effects:
[0016] 1. The utility model solves the problem of splashing when the feed raw materials are crushed, which easily leads to raw material loss and cost increase by arranging dustproof plates, crushing boxes, crushing rollers, crushing shafts and cover plates. When adding materials, the feed raw materials are added from the feed hopper and enter the feed port. The raw materials abut the dustproof plates and enter the crushing box. After the raw materials have completely entered, the dustproof plates return to their original shape under gravity, and the bottom end of the dustproof plates will continue to contact the upper inclined surface of the base plate and continue to close the feed port, so that subsequent crushing operations will not have debris splashing out, reducing material waste and avoiding cost increase. The dustproof plates are in an inclined state in a normal state. When gravity returns to its original state, it can ensure that the bottom end of the dustproof plates contacts the upper inclined surface of the base plate and ensures the closure of the crushing box feed port.
[0017] 2. The utility model solves the problem of lack of multi-stage crushing processing function by setting crushing rollers and crushing shafts. After the raw materials enter the crushing box, they first enter between the two crushing rollers and are crushed. No matter they are granular, cylindrical, or large and irregular shapes, they can be crushed to avoid the blocks being too large to affect the subsequent cutting and separation. Hard materials will also be crushed to achieve a one-time crushing process, and then fall downwards, and then contact the crushing shaft and the cutting knife on its periphery, and undergo a secondary cutting and crushing process under the high-speed rotation of the cutting knife.
[0018] 3. The utility model solves the problems of raw materials falling too fast during crushing, short contact time with the cutting knife, and low crushing efficiency by arranging crushing rollers, crushing shafts, crushing chambers, and crushing chambers; after the raw materials enter the crushing chamber, they pass between the two crushing rollers and are crushed, and then enter the crushing chamber, and are finally cut and crushed by the high-speed rotating cutting knife. However, they will not fall directly after being crushed, and some of them will still be temporarily retained in the crushing chamber between the two substrates, so they will be cut and processed again until the small-sized materials are finally discharged downward from the discharge slot, which buffers the crushing and cutting space of the materials, prolongs the cutting time, increases the cutting and crushing efficiency, and avoids them falling directly after being cut once.

DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0032] See also Figure 1-9 As shown, the utility model is a splash-proof feed raw material crushing equipment, including a crushing box 1, a lower hopper 2, a cover plate 3, a feed hopper 4, a crushing roller 5, a crushing shaft 6 and a dust plate 7. A crushing cavity 103 is provided in the crushing box 1. Two crushing rollers 5 are rotatably connected to the two inner end walls of the crushing box 1 in the crushing cavity 103. The outer periphery of the crushing roller 5 is fixed with equidistantly distributed sharp teeth 501. A crushing cavity 104 is provided in the crushing box 1 below the crushing cavity 103. The crushing box 1 in the crushing chamber 104 is rotatably connected to the two inner end walls with crushing shafts 6, and the outer periphery of the crushing shaft 6 is fixed with equidistantly distributed crushing knives 601, the bottom end of the crushing box 1 is fixed with a lower hopper 2, the top of the crushing box 1 is fixed with a cover plate 3, and the top of the crushing box 1 below the cover plate 3 is also provided with two symmetrical feed ports 102, each of which is fixed with a feed hopper 4, and the top of the crushing box 1 in the feed port 102 is rotatably connected to a dustproof plate 7;
[0033] The crushing box 1 is provided with a crushing chamber 103 and a crushing chamber 104 from top to bottom. When the material enters the crushing chamber 103, the two crushing rollers 5 rotate in opposite directions. The material passes between the two crushing rollers 5 and is crushed. The material is then scraped by the sharp teeth 501 on the surface of the crushing rollers 5, reducing the particle size of the material and effectively crushing large pieces of material, hard materials, and long strips of material. The crushed material then enters the crushing box 1 and is cut by the high-speed rotation of the crushing shaft 6, which drives the high-speed rotation of the crushing blade 601, quickly breaking it into smaller particles and even achieving a cutting and powdering operation. Finally, the material enters the lower hopper 2 for discharge.
[0034] Before the raw materials are fed into the feed hopper 4 , they enter the feed port 102 and push open the dustproof plate 7 to enter the inner cavity of the crushing box 1 .
[0035] Two symmetrical base plates 105 are fixed in the crushing box 1 outside the crushing cavity 103. The opposite surfaces of the two base plates 105 are curved and surround the crushing cavity 103. The upper surfaces of the two base plates 105 are inclined.
[0036] The two substrates 105 cooperate with each other to form a crushing chamber 103, so that the shape of the crushing chamber 103 is slightly larger than the rotation path of the two crushing rollers 5, and the substrate 105 is an inclined surface, so that the bottom of the dustproof plate 7 contacts the upper end of the substrate 105, closing the feed port 102 to prevent debris from flying out during crushing, and the crushing chamber 103 is open at the top and bottom.
[0037] Axles 701 are fixed to both ends of the top of the dustproof plate 7, and the axles 701 are rotatably connected to the end wall of the crushing box 1. The top of the dustproof plate 7 contacts the bottom surface of the cover plate 3, and the bottom of the dustproof plate 7 contacts the upper inclined surface of the base plate 105.
[0038] The setting of the shaft 701 allows the dustproof plate 7 to rotate. The dustproof plate 7 rotates open when feeding, so that the bottom end of the dustproof plate 7 is separated from the upper inclined surface of the substrate 105. After feeding, it returns to its original shape under gravity, and the bottom of the dustproof plate 7 continues to contact the upper inclined surface of the substrate 105 to close the feeding port 102.
[0039] Two symmetrical second substrates 106 are fixed in the crushing box 1 outside the crushing chamber 104, and the opposing surfaces of the two second substrates 106 are both arc-shaped surfaces and surround the crushing chamber 104. The gap between the upper ends of the two second substrates 106 is set as the feed slot 1041, and the gap between the lower ends of the two second substrates 106 is set as the discharge slot 1042. The size of the discharge slot 1042 is smaller than that of the feed slot 1041. The crushing chamber 104 is connected to the crushing chamber 103 through the feed slot 1041.
[0040] The two substrates 106 cooperate with each other to form a crushing chamber 104. The size of the crushing chamber 104 is slightly larger than the rotation path of the crushing shaft 6 and the cutting knife, and the crushing chamber 104 receives the crushed material from the crushing chamber 103 through the feed slot 1041. After entering the crushing chamber 104, the high-speed rotation of the crushing shaft 6 and the cutting knife further shreds the material, and finally discharges it downward from the discharge slot 1042.
[0041] A motor 1 502 and a motor 2 602 are fixed to one end of the crushing box 1, and the output shaft of the motor 1 502 is connected to the end of a crushing roller 5. A gear 503 is fixed to the end of the two crushing rollers 5 away from the motor 1 502, and the two gears 503 are meshed with each other.
[0042] Motor 1 502 drives one crushing roller 5 to rotate, and the other crushing roller 5 also rotates due to the mutual engagement of the two gears 503. Since the rotation directions of the gears 503 are opposite, the two crushing rollers 5 will rotate in opposite directions, toward the center of the two crushing rollers 5, and quickly crush the material passing between the two crushing rollers 5.
[0043] The output shaft of the second motor 602 is connected to the end of the crushing shaft 6; the second motor 602 drives the crushing shaft 6 to rotate, so that the cutting blades on its periphery rotate rapidly, and the crushed materials are quickly cut and crushed.
[0044] Symmetrically distributed legs 101 are fixed to both outer side walls of the crushing box 1. The upper end of the lower hopper 2 is connected to the interior of the crushing box 1, and the bottom end of the lower hopper 2 is an open structure.
[0045] The crushing box 1 is stably supported by the support legs 101 so that it is at a certain height from the ground, and the bottom of the lower hopper 2 is open, and the crushed materials are directly discharged from the bottom of the lower hopper 2.
[0046] The specific working principle of the present invention is as follows: first, add raw materials into the crushing box 1, add feed raw materials from the feed hopper 4, enter the feed port 102, and the raw materials push the dust plate 7 to enter the crushing box 1. After the raw materials are completely entered, the dust plate 7 returns to its original shape under gravity, and the bottom end of the dust plate 7 will continue to contact the upper inclined surface of the base plate 105, and will continue to close the feed port 102, so that no debris will splash out during the subsequent crushing operation. When the material enters the crushing chamber 103, the motor 502 drives one crushing roller 5 to rotate, and the other crushing roller 5 also rotates because of the mutual engagement of the two gears 503. Because the rotation directions of the gears 503 are opposite, the two crushing rollers 503 are opposite to each other. The crushing rollers 5 rotate in opposite directions, and the raw material passes between the two crushing rollers 5 and is crushed. It is then scraped by the sharp teeth 501 on the surface of the crushing roller 5, making the particle size of the raw material smaller. The raw material then falls downward and enters the crushing chamber 104 through the feed slot 1041. The second motor 602 drives the crushing shaft 6 to rotate, thereby causing the cutting blades on its periphery to rotate rapidly. The material is cut and crushed by the high-speed rotating cutting blades, but it does not fall directly after being crushed. Some of it will still be temporarily retained in the crushing chamber 104 between the two second substrates 106, so it will be cut and processed again until the small-sized material is finally discharged downward from the discharge slot 1042. Finally, the crushed material is directly discharged from the bottom of the lower hopper 2.
[0047] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
