Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a raw material pretreatment device for feed processing. Background Technology

[0002] Feed is a general term for the food of all domesticated animals. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Before refining, livestock feed needs to undergo pre-treatment steps such as screening, cleaning, drying, and crushing. Screening of raw materials is particularly critical. It is necessary to remove large particles that are not completely crushed or foreign objects such as gravel mixed in with the raw materials before proceeding with subsequent operations to avoid affecting the precision of subsequent processing. In the current technology, feed screening generally involves directly pouring a lot of material onto an inclined filter screen, and screening is carried out as the material moves down. This screening method is not precise enough and is prone to material accumulation, resulting in low screening efficiency. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a raw material pretreatment device for feed processing. The raw material pretreatment device for feed processing includes a screening component 1 and a driving component 2. The screening component 1 screens the material and removes large particles that do not meet the standards, making it easier to carry out further crushing operations. At the same time, the driving component 2 can control the feeding speed and feeding amount to avoid material accumulation on the filter screen, which would affect the screening efficiency.

[0028] Specifically, the screening component 1 includes a box body 11 and a sealed door 12 fixed to one side of the box body 11. The door 12 can be fixed to the box body 11 by bolts or other means, which facilitates cleaning of the inside of the box body 11 after opening. A transparent glass plate can also be installed in the middle to facilitate the staff to observe the internal condition of the box body 11 and to detect emergencies in time. A hopper 13 is fixed to the top of the box body 11. The staff puts the material to be screened into the hopper 13 and then drops it onto the filter screen 14 for screening. The filter screen 14 is installed inside the box body 11. One end of the filter screen 14 is rotatably connected to the inner wall of the box body 11. The two are rotatably connected by a shaft. The filter screen 14 is lower at one end and the other end is higher at the material drop position, which facilitates the downward discharge of the material. A receiving part 15 is provided on one side of the box body 11. The receiving part 15 can receive the screened material with larger particles that do not meet the standards, which facilitates the staff to crush it again.

[0029] The drive assembly 2, located on one side of the housing 11, includes a drive component 21 fixed to one side of the housing 11. A connecting rod 22 is fixed to the output end of the drive component 21, and an eccentric block 23 is fixed to its end. A buffer block 24 that cooperates with the eccentric block 23 is fixed to the top of the filter screen 14. The drive component 21 drives the connecting rod 22 and the eccentric block 23 to rotate. The continuous rotation of the eccentric block 23 impacts the buffer block 24, thereby impacting the filter screen 14 and causing its end to vibrate continuously, thus improving the filtration efficiency. A fixed shaft 25 is rotatably connected inside the hopper 13, and its end cooperates with the drive component 21. A baffle 26 is fixed to the surface of the fixed shaft 25. The drive component 21 can simultaneously drive the fixed shaft 25 and the baffle 26 to rotate, thereby intermittently discharging the material downward through the baffle 26, thus preventing the material from accumulating on the filter screen 14 and affecting its filtration efficiency.

[0030] Example 2

[0031] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the screening component 1 also includes a support base 16 fixed to the bottom of the housing 11, with an anti-slip pad 17 fixed to its bottom. The support base 16 and the anti-slip pad 17 make the operation of the device more stable and can absorb part of the vibration force of the filter screen 14, further improving its stability.

[0033] The screening component 1 also includes a feeding frame 18 that slides inside the box 11. A receiving block 19 is fixed to the bottom wall of the box 11. A handle is fixed to the end of the feeding frame 18 to facilitate the staff to pick up the feeding frame 18. After screening, qualified materials fall from the filter screen 14 into the feeding frame 18 for collection, so that the staff can take them out for subsequent processes.

[0034] The receiving component 15 includes a snap-fit ​​seat 151 fixed to one side of the housing 11. A discharge port 152 is provided on one side of the housing 11. The snap-fit ​​seat 151 is located at the bottom of the discharge port 152. A snap-fit ​​groove 153 is provided inside the snap-fit ​​seat 153. The snap-fit ​​groove 153 is T-shaped and cooperates with the snap-fit ​​seat 151 to facilitate the limiting and fixing of the receiving box 155, making its installation more convenient and stable. The receiving component 15 also includes a snap-fit ​​block 154 that slides in the snap-fit ​​groove 153. The receiving box 155 is fixed to one side of the snap-fit ​​block 154.

[0035] During installation, the snap-fit ​​block 154 slides within the snap-fit ​​groove 153 until it aligns with the discharge port 152. At this point, the unqualified material is discharged from the discharge port 152 into the receiving box 155 for collection. Since both sides of the snap-fit ​​groove 153 are open, when the receiving box 155 is almost full, the empty receiving box 155 can be directly installed into the snap-fit ​​base 151, and the nearly full receiving box 155 can be gradually pushed out. Since the two receiving boxes 155 are in contact, the material will not spill to the outside during the replacement process.

[0036] The receiving component 15 also includes a baffle plate 156, which is fixed on both sides of the inner wall of the discharge port 152 and located at the end of the filter screen 14. The baffle plate 156 is symmetrically inclined and is used to guide the screened material into the receiving box 155 near the middle position to prevent leakage from both sides.

[0037] The drive component 21 includes a drive motor 211 fixed to the end of the connecting rod 22, and a mounting base 212 fixed to its bottom. One side of the mounting base 212 is fixed to the housing 11, and the drive motor 211 is fixed by the mounting base 212 to make its installation more stable.

[0038] The drive unit 21 also includes a fixing block 213 fixed to the inner wall of the housing 11, which is located below the filter screen 14. A buffer spring 214 is fixed to the top of the fixing block 213, and its top end is fixed to the filter screen 14. The buffer spring 214 and the eccentric block 23 can make the filter screen 14 vibrate continuously, thereby making its screening effect better.

[0039] The drive unit 21 also includes a drive gear 215 fixed to the output end of the drive motor 211, and a driven gear 216 fixed to the end of the fixed shaft 25, which meshes with the drive gear 215. When the drive motor 211 rotates, the driven gear 216 is driven to rotate through the drive gear 215. The diameter of the drive gear 215 is smaller than the diameter of the driven gear 216. Therefore, the rotation speed of the driven gear 216 and the fixed shaft 25 is relatively low, thereby controlling the feeding speed and avoiding the situation of accumulation caused by feeding too fast.

[0040] Multiple baffles 26 are provided and evenly distributed on the surface of the fixed shaft 25. Their ends contact the inner wall of the hopper 13. The multiple baffles 26 are evenly distributed so that a feeding area is formed between every two adjacent baffles 26. During the rotation of the fixed shaft 25 and the baffles 26, the material is intermittently discharged downward from this area, thereby avoiding the hopper 13 from becoming blocked. At the same time, the feeding speed is kept low, avoiding the accumulation of material on the filter screen 14 and the occurrence of incomplete screening.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
