Description

Technical Field

[0001] The utility model relates to the technical field of feed processing equipment, in particular to a feed crushing device capable of multi-stage screening. Background Art

[0002] The multi-stage screening feed crushing device not only improves the nutritional value and digestibility of the feed by crushing the raw materials and grading them according to particle size, but also optimizes the production, storage and transportation process of the feed. It is an indispensable key equipment in modern animal husbandry and feed industry.

[0003] Although current technology has many advantages, its disadvantage is that some feed crushing devices will use fan blades to spread the feed evenly on the screen during multi-stage screening. Smaller feed will fall through the screen and larger feed will be discharged from the discharge port. However, some smaller feed may not have time to pass through the screen before being driven to the discharge port by the fan blades, resulting in the feed not being evenly screened, affecting product quality and uniformity. At the same time, some feed has a certain amount of oil. After crushing, the oil will cover the surface of the feed. When the feed passes through the screen, the screen may be blocked by the oil. However, current technology simply uses bristles to clean the screen. For filter holes that are severely blocked, simply using bristles cannot completely clean the screen, resulting in the material being unable to pass through the screen holes smoothly, thereby greatly reducing screening efficiency, affecting production speed, and may also result in unqualified products, increasing the risk of rework or waste.

[0023] like Figure 4 and Figure 5 As shown, the cleaning mechanism includes a plurality of fixed columns 13, the outer surfaces of the plurality of fixed columns 13 are fixedly connected with springs 14, the outer surfaces of the plurality of springs 14 are fixedly connected with rubber parts 15, the inner surfaces of the plurality of rubber parts 15 are fixedly connected with working rods 16, the outer surfaces of the plurality of working rods 16 are movably provided with rotating blocks 17, the outer surfaces of the plurality of rotating blocks 17 are fixedly connected with fixed rods 18, and the outer surfaces of the plurality of fixed rods 18 are movably provided with rollers 19, thereby avoiding the problem of unclean cleaning with a brush, ensuring screening efficiency and production speed, and reducing the risk of rework and waste caused by unqualified products.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the crushing equipment 2 is arranged on the top of the support frame 1, the rotating shaft 7 is movably embedded in the inner surface of multiple screening unit blocks 3, and multiple fan blades 9, gathering blocks 10 and dispersion blocks 11 are all movably embedded in the inner surface of multiple screening unit blocks 3. The shapes of multiple fan blades 9, gathering blocks 10 and dispersion blocks 11 are all arc-shaped. The support frame 1 can support the crushing equipment 2 and provide a good working environment for the crushing equipment 2.

[0025] like Figure 5 As shown, multiple fixed columns 13, springs 14, rubber parts 15 and working rods 16 are all movably embedded in the inner surfaces of multiple slots 12. The slots 12 can limit the moving trajectory of the rubber parts 15 to prevent the rubber parts 15 from derailing and affecting the use of the equipment.

[0026] Working principle: This equipment is a feed crushing device capable of multi-stage screening. When in use, start the motor 6 on the support plate 5. The motor 6 drives the rotating shaft 7 to rotate through the output shaft, and the rotating shaft 7 drives the distribution plate 8 to rotate. The crushed feed falls from the crushing device 2 on the support frame 1 to the distribution plate 8. The distribution plate 8 uses rotation to evenly spread the crushed material inside the first layer of screening units. Because the motor 6 rotates counterclockwise first, the multiple fan blades 9 drive the multiple gathering blocks 10 to rotate, and the gathering blocks 10 disperse the feed dispersed on the first layer of screening unit blocks 3 into the lower layer of screening unit blocks 3 through the filter holes 20. When the multiple gathering blocks 10 rotate, their arc-shaped design causes the air to be accelerated when it flows through the concave surface of the gathering blocks 10. According to Bernoulli's principle, the pressure in the area where the flow rate increases decreases, so a relatively low-pressure area is formed near the concave surface of the gathering block 10, and the low-pressure area attracts surrounding air and feed particles. The particles flow toward the center, thereby causing the feed to gather in the middle and not be discharged from the discharge pipe 4. The filter holes 20 on each layer of the screening unit block 3 are of different sizes. The filter holes 20 on the top layer are the largest, and the filter holes 20 on the bottom layer are the smallest. Therefore, the size distribution of the feed on the multiple screening unit blocks 3 decreases from top to bottom. When the screening unit blocks 3 of each layer are no longer unloading, the rotation of the motor 6 is stopped and the motor 6 is rotated in the opposite direction. At this time, the multiple fan blades 9 will drive the multiple dispersion blocks 11 to rotate, and the convex surface thereof faces the direction of rotation. The air is pushed by the dispersion block 11 and flows out faster along the convex surface. Due to the streamline characteristics of the convex surface, the air forms a high-pressure area at the edge of the dispersion block 11. The air in the high-pressure area will push the feed outward. Due to the rotational motion of the dispersion block 11, the material is pushed to the edge area, and then the multiple dispersion blocks 11 push the feed on the screening unit block 3 of each layer to the edge, and finally the feed is discharged from the discharge pipe 4.

[0027] When the fan blade 9 has not rotated to the blocked filter hole 20, the spring 14 on the fixed column 13 has elastic potential energy. When the fan blade 9 rotates to the blocked filter hole 20, the spring 14 will release the elastic potential energy, so that the rubber part 15 and the working rod 16 move on the inner surface of the slot 12, and the working rod 16 will drive the rotating block 17 to move downward, and the rotating block 17 will drive the roller 19 to move downward through the fixed rod 18. The size of the filter hole 20 is much larger than the rotating block 17, so a small part of the rotating block 17 and the roller 19 will be inserted into the filter hole 20, and the diameter of the filter hole 20 is small at the top and large at the bottom, so as long as the entrance of the filter hole 20 is opened, the filter hole 20 can be dredged, and when the fan blade 9 continues to rotate, the roller 19 will be temporarily hindered by the filter hole 20, and will rotate and move upward out of the filter hole 20, indirectly squeezing the spring 14 so that the spring 14 obtains elastic potential energy.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
