TECHNICAL FIELD
[0001] The utility model belongs to screening device technical field, concretely relates to a raw material screening device for piglet feed processing. BACKGROUND
[0002] Feed is an important way for piglets to obtain energy, especially energy feed such as corn, sorghum, etc., which is rich in easily digestible starch and can provide a large amount of energy support for piglets. In addition, feed can also provide piglets with necessary nutrients such as protein, vitamins and minerals, which are essential for the growth and development of piglets. Specifically, feed can help piglets increase their feed intake and lay a foundation for healthy growth. When milk is insufficient in the late lactation period, feed can be used as a supplement to ensure that piglets get enough nutrients. At the same time, feed is also helpful for the development of piglets' gastrointestinal tract, reducing intestinal villus damage caused by weaning stress and improving the weight gain rate of piglets after weaning.
[0003] Feed has various particle size specifications, and each specification of feed corresponds to different feeding needs, so the specification of feed needs to be screened, which requires the use of a screening device. During the use of the screening device, the applicant found that the screening hole diameter size of the screening device in the prior art is fixed, and the particle size corresponding to the screening requirement can be obtained only by replacing the screening plate. However, the hole diameter of the screening plate is still fixed, that is, it cannot be adjusted flexibly. When there is no screening plate with the corresponding requirement hole diameter, it is necessary to customize and purchase, which is not good in terms of economy. Therefore, structural optimization is needed. SUMMARY

[0025] In order to make the person skilled in the art can better understand the utility model, the utility model technical scheme is further explained below in combination with the drawings and examples.
[0026] For example, Figures 1-4As shown, this utility model discloses a raw material screening device for piglet feed processing, comprising a machine base 1, a cylinder frame 2, a feeding bin 3, and a vibrating motor 4 mounted on the machine base 1. A screening bin 5 is hinged to the machine base 1. The output end of the vibrating motor 4 contacts the outer wall of the screening bin 5. Several sets of chutes 6 are arranged longitudinally inside the screening bin 5. Each set of chutes 6 is equipped with a screening plate 7. Each screening plate 7 has screening holes 8. The diameter of the screening holes 8 on each screening plate 7 is different. Between two adjacent screening plates 7, the screening plate 7 with larger diameter screening holes 8 is located on the upper side. The screening plate 7 is provided with inserts. Slot 9 and slot 9 are slidably installed with an adjustment plate 10. The adjustment plate 10 is provided with an adjustment hole 11 whose size and position match the screen hole 8. The side of the adjustment plate 10 protrudes from the screen bin 5. The screen bin 5 is provided with a sliding opening 12 whose position corresponds to the adjustment plate 10. The adjustment plate 10 is located in the sliding opening 12. The adjustment plate 10 is connected to a vertical plate 13. Limiting plates 14 are installed on both sides of the vertical plate 13 in the screen bin 5. The two limiting plates 14 are provided with a placement groove 15. A T-shaped block 16 is inserted into the placement groove 15. A screw 17 is installed between the vertical plate 13 and the T-shaped block 16. The screw 17 is threadedly connected with several nuts 18.
[0027] The side of the screening bin 5 is provided with an opening 19, and a baffle 20 is hinged to the opening 19. The opening 19 is located on the upper side of the side of the screening plate 7, and the opening 19 is connected to the discharge trough 21.
[0028] The cylinder frame 2 is equipped with a cylinder 22, and the machine base 1 is provided with a clearance opening 23. The output end of the cylinder 22 is placed in the clearance opening 23, and the output end of the cylinder 22 is connected to the bottom of the screen bin 5.
[0029] In this implementation example, when using a raw material screening device for piglet feed processing, the vibration motor 4 is started, driving the screening bin 5 to vibrate. The raw material is introduced from the upper side of the screening bin 5 and falls onto the screening plate 7. While being evenly spread by the shaking screening plate 7, the raw material is screened by its screening holes 8. After falling onto the lower screening plate 7, it undergoes another screening. Multi-stage screening enhances the screening effect and obtains raw materials with different particle sizes corresponding to the specifications of the screening holes 8. The raw material after multiple screenings is discharged and collected from the discharge bin 3. After the raw material screening is completed, the vibration... When motor 4 stops, cylinder 22 runs, pushing screen bin 5 to tilt around its hinge axis with the machine base 1, so that the raw material on screen plate 7 is discharged from the corresponding opening 19. When tilting, baffle 20 will also open opening 19 under its own weight, and the corresponding specification of raw material can be received at the discharge trough 21. It should be emphasized that, depending on the actual situation, if the raw material on the upper side of screen bin 5 is poured in too fast, causing excessive accumulation on screen plate 7, baffle 20 needs to be fixed to prevent the raw material from being spread evenly due to the vibration of motor 4 and being discharged directly from opening 19.
[0030] Furthermore, when it is necessary to adjust the aperture of the screening hole 8 of the screening plate 7, the adjusting plate 10 in the slot 9 is pulled, so that the relative position between the adjusting hole 11 and the screening hole 8 changes, and the passage gap between the adjusting hole 11 and the screening hole 8 will change, thereby achieving the purpose of changing the aperture. After the adjustment is completed, the position of the upright plate 13 is fixed by the nut 18 in conjunction with the screw 17 and the T-block 16, thus fixing the position of the adjusting plate 10 and preventing the adjusting plate 10 from changing position during the shaking process.
[0031] The preferred feeding bin 3 is truncated cone-shaped, with the output end of the feeding bin 3 protruding from the side of the screening bin 5. This design has a converging effect, which is conducive to the receiving of feed and is not easily interfered with. In fact, the structural shape of the feeding bin 3 can also be considered according to the specific situation.
[0032] It is preferred that there be at least three screen plates 7. This design achieves the purpose of multi-stage screening. In fact, the number of screen plates 7 can also be considered according to the specific situation.
[0033] The edge of the preferred sliding opening 12 is provided with a dustproof sealant. This design prevents feed from flying out of the gap. In fact, anti-splashing measures can also be considered depending on the specific situation.
[0034] The preferred adjustment plate 10 is provided with two ear plates 101, and the screening bin 5 is provided with two sets of auxiliary limiting plates 102 located on both sides of the ear plates 101. With this design, the position movement of the auxiliary adjustment plate 10 and the stability of its use are improved. In fact, measures to move the position of the auxiliary adjustment plate 10 can also be considered according to the specific situation.
[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
