Description

Technical Field

[0001] This utility model belongs to the field of feed production and grinding technology, specifically referring to a feed grinding device used in feed production. Background Technology

[0002] Feed grinding is a crucial step in modern livestock production, directly impacting the growth and development of livestock and poultry and the profitability of farming. Existing feed grinding devices, such as the feed raw material grinding device disclosed in application number CN202421222167.8, use reverse rotation of grinding blades to cut feed raw materials, thereby improving the grinding effect.

[0003] However, in the actual crushing process, the feed will pass through the crushing blades quickly under the action of gravity, which makes it difficult to guarantee the crushing effect. If the particles are too large, it will seriously affect the quality of the feed. In actual production, different sizes of feed particles are required according to different livestock and poultry feeds. Simple crushing is difficult to meet the actual needs. Using subsequent screening is not only a waste of manpower, but also inefficient. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a feed grinding device for feed production, which effectively solves the problem that the existing feed grinding devices are difficult to maintain the uniformity of feed grinding effect, thus making it impossible to guarantee the quality. It also solves the problems of not being able to classify the ground feed by size and the low efficiency of subsequent screening and processing.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a feed crushing device for feed production, including a base with a through-type central section. A crushing box with a top opening is fixed to the upper end of the base. An annular guide rail is fixed to the inner wall of the crushing box, and a sieving crushing mechanism is connected to the guide rail. A fine material distribution mechanism is connected to the inner wall of the base. The sieving crushing mechanism includes a screen cylinder rotatably connected to the guide rail, and the upper end of the screen cylinder has an opening. A rotating shaft is rotatably connected to the inner wall of the crushing box, and the other end of the rotating shaft passes through the screen cylinder and is rotatably connected to one end inside the screen cylinder. At the same time, several crushing blades are evenly distributed on the side wall of the rotating shaft. A symmetrically distributed L-shaped guide plates are fixed to the upper end of the inner wall of the crushing box, and the distance between the two guide plates is much smaller than the opening at the top of the screen cylinder. A guide slope is provided at the bottom of the base.

[0006] As an improvement to this solution, a connecting shaft is fixed to the end of the sieve cylinder away from the rotating shaft, and the connecting shaft passes through the crushing box. At the same time, a vertical swing rod is fixed to the end of the connecting shaft outside the crushing box. A driving slider is sleeved on the swing rod, and the driving slider slides on the swing rod.

[0007] As an improvement to this solution, a screening motor and a drive motor are respectively fixed on the two side walls of the crushing box by brackets. The output shaft of the screening motor is provided with an eccentric wheel, and the outer edge of the eccentric wheel is provided with a shaft body and rotatably connected to the drive slider. The output shaft of the drive motor is connected to the rotating shaft.

[0008] As an improvement to this solution, the fine material distribution mechanism is located below the sieving and crushing mechanism, and the fine material distribution mechanism includes a slide rod, a support slider and a fine sieve plate. The slide rod is vertically fixed to the inner wall of the base, and the support slider is slidably connected to the slide rod. The fine sieve plate is fixed to the support slider and is parallel to the top of the slide rod.

[0009] As an improvement to this solution, a drive sliding shaft is fixed on the outer wall of the fine sieve disc near the swing arm, and a drive sliding groove is provided on the swing arm, with the drive sliding shaft slidably connected in the drive sliding groove.

[0010] As an improvement to this solution, the drive slider is arranged in a U-shape, and the fine screen disc has an opening on the side away from the swing arm, through which feed can be discharged.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows: 1. It is equipped with a screening and crushing mechanism. Through the reciprocating swinging screen cylinder, it can retain the feed that is still too large after crushing. With the help of the internal crushing blades, the feed can be further crushed and cut until the particle size can pass through the screen cylinder. 2. By setting a fine material distribution mechanism below the sieving and crushing mechanism, the crushed feed can be further screened, and the feed particles that are cut by the crushing blades can be screened out to be smaller and finer, thereby realizing the classification of feed grades and meeting different market demands. 3. The overall structure is reasonably designed. Through automatic cutting and screening from top to bottom, it saves production steps and improves efficiency. Furthermore, the drive of the screen cylinder and fine screen disc is achieved by a set of motors, which reduces production costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a feed grinding device for feed production, comprising a base 1 with a through-center, a grinding box 2 with a top opening fixed to the upper end of the base 1, an annular guide rail 3 fixed to the inner wall of the grinding box 2, and a sieving and grinding mechanism 4 connected to the guide rail 3, and a fine material distribution mechanism 8 connected to the inner wall of the base 1; the sieving and grinding mechanism 4 includes a screen cylinder 5 rotatably connected to the guide rail 3, and the upper end of the screen cylinder 5 is provided with an opening, a rotating shaft 6 rotatably connected to the inner wall of the grinding box 2, and the other end of the rotating shaft 6 passes through the screen cylinder 5 and is rotatably connected to one end inside the screen cylinder 5, while a plurality of grinding blades 7 are evenly distributed on the side wall of the rotating shaft 6; By sliding the screen cylinder 5 along the guide ring rail 3, the feed raw materials inside can fully contact the crushing blades 7, improving the crushing efficiency. Under the action of the through holes in the screen cylinder 5, the feed can be discharged after being cut into small pieces.

[0017] like Figure 1 and Figure 2 As shown, the upper end of the inner wall of the crushing box 2 is fixed with symmetrically distributed L-shaped guide plates 12, and the distance between the two guide plates 12 is much smaller than the opening at the top of the screen cylinder 5. The bottom of the base 1 is provided with a guide slope 13. The feed raw materials are fed into the screen cylinder 5 by two sets of guide plates 13 with a small spacing, and the material can be continuously fed into the screen cylinder 5 during the reciprocating rotation of the screen cylinder 5.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, in order to drive the sieving and crushing mechanism 4 and the fine material distribution mechanism 8, a connecting shaft 14 is fixed at the end of the screen cylinder 5 away from the rotating shaft 6, and the connecting shaft 14 passes through the crushing box 2. At the same time, a vertical swing rod 15 is fixed at the end of the connecting shaft 14 outside the crushing box 2. A driving slider 16 is sleeved on the swing rod 15, and the driving slider 16 slides on the swing rod 15. A screening motor 17 and a driving motor 18 are respectively fixed on the two side walls of the crushing box 2 by brackets. The output shaft of the screening motor 17 is provided with an eccentric wheel 19, and the outer edge of the eccentric wheel 19 is provided with a shaft body and rotatably connected to the driving slider 16. The output shaft of the driving motor 18 is connected to the rotating shaft 6.

[0019] like Figure 1 and Figure 2 and Figure 4 As shown, the fine material distribution mechanism 8 is located below the sieving and crushing mechanism 4, and the fine material distribution mechanism 8 includes a slide rod 9, a support slider 10 and a fine screen 11. The slide rod 9 is vertically fixed to the inner wall of the base 1, and the support slider 10 is slidably connected to the slide rod 9. The fine screen 11 is fixed to the support slider 10 and is parallel to the top of the slide rod 9. The fine sieve 11 can further refine the pulverized feed, meeting the feeding needs of different livestock and poultry.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, in order to drive the fine sieve disc 11, a drive sliding shaft 21 is fixed on the outer wall of the fine sieve disc 11 near the swing arm 15. The swing arm 15 is provided with a drive sliding groove 20, and the drive sliding shaft 21 is slidably connected in the drive sliding groove 20.

[0021] like Figure 2 and Figure 3 As shown, the drive slider 16 is arranged in a U-shape, and the fine screen plate 11 has an opening on the side away from the swing arm 15, through which feed can be discharged.

[0022] In practical use, feed ingredients are added to the top of the crushing box 2, allowing them to pass through the opening at the top of the screen cylinder 5 along the guide plate 12 and into the screen cylinder 5. The drive motor 18 is turned on, causing the rotating shaft 6 to rotate, which in turn causes the crushing blades 7 to crush and cut the feed ingredients. The crushed feed falls through the through-holes in the screen cylinder 5 onto the fine screen plate 11. Simultaneously, the screening motor 17 is turned on, causing the eccentric wheel 19 to rotate. The drive slider 16, connected to the eccentric wheel 19, rotates accordingly and slides along the swing arm 15, causing the swing arm 15 to swing about the connecting shaft 14. At this time, the connecting shaft 14, under the action of the swing arm 15, drives the screen cylinder 5... The feed material inside the device reciprocates along the guide ring rail 3 and is coaxial with the guide ring rail 3, allowing the feed material to shake and come into contact with the crushing blades 7 for crushing. As the swing arm 15 swings, the drive slide 20 drives the drive slide shaft 21 and the fine screen 11 connected to it to move. At this time, the fine screen 11 moves left and right along the slide rod 9 under the support of the support slider 10, so that the feed crushed on it is further screened through the through holes on the fine screen 11. The finer feed falls to the guide slope 13 and slides out, while the larger feed is discharged from the other direction along the fine screen 11. The above is the entire process of using the feed crushing device for feed production.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
