Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a fine grinding device for feed processing. Background Technology

[0002] In the modern feed processing industry, as the livestock industry continues to raise its requirements for feed quality, the fine grinding of feed raw materials has become a key link in ensuring the nutritional balance of feed and improving the digestibility and absorption efficiency of animals. Fine grinding can not only make the feed particles uniform in size and enhance palatability, but also promote the full mixing of additives and basic raw materials, thereby improving the overall performance of the feed.

[0003] However, existing feed processing methods often result in incompletely crushed coarse particles after grinding, leading to incomplete separation between fine and coarse particles. This significantly affects the uniformity of the finished feed product. Furthermore, the presence of coarse particles mixed with fine particles results in a large total amount to be screened, making the screening of coarse particles after grinding time-consuming.

[0004] Furthermore, when feed requires modification processing, the mixing of additives and grinding materials usually needs to be carried out by a separate mixing device after grinding. This not only increases equipment investment and floor space, but also affects the overall efficiency of modification processing due to the waiting time for the grinding mill to discharge. Therefore, a fine grinding device for feed processing is needed to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this invention is to provide a fine grinding device for feed processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fine grinding device for feed processing, comprising a grinding equipment platform and a grinder for grinding feed raw materials. The grinder is fixed on the platform of the grinding equipment platform. A blower screening mechanism is embedded and fixed on one side of the grinding equipment platform. The blower screening mechanism includes a horizontal air duct, a blower, and an intercepting net. The horizontal air duct is embedded and fixed in a groove of the grinding equipment platform. The blower is fixed at one end of the horizontal air duct. The intercepting net is fixed on the inner wall of the horizontal air duct. An adding mechanism is provided in front of the blower screening mechanism.

[0007] Preferably, the addition mechanism includes an additive funnel, a metering pump, and a feed pipe. The feed pipe is connected to and fixed on one side surface of the tilting air duct, the metering pump is fixed at the upper end of the feed pipe, and the additive funnel is fixed at the upper end of the metering pump.

[0008] Preferably, a material discharge port is provided at the junction of the horizontal air duct and the grinding machine, and the material discharge port of the horizontal air duct is connected to the discharge port of the grinding machine.

[0009] Preferably, one end of the horizontal air duct is fixed to a tilting air duct, and the lower end of the horizontal air duct is rotatably connected to a flipping block plate, and the rotating shaft of the flipping block plate is fitted with a torsion spring.

[0010] Preferably, the front end face of the grinding equipment platform is provided with an operating port, the flipping blocking plate is rotatably connected to the operating port of the grinding equipment platform, one end of the torsion spring is fixed to the end face of the flipping blocking plate, and the other end of the torsion spring is fixed to the wall of the horizontal air duct.

[0012] This utility model provides a fine grinding device for feed processing, which has the following advantages compared with the prior art:

[0013] The set-up blower screening mechanism uses wind power to convey and intercept the feed grinding material to screen it. It can accurately separate fine powder and coarse material. Compared with traditional screening methods, it can effectively improve the fineness and quality uniformity of the feed grinding material. In addition, timely screening during the continuous and small-volume discharge of the grinder can reduce the trouble of interception screen clogging.

[0014] With the addition mechanism and horizontal air duct, the metering pump can quantitatively add the additive from the additive funnel into the air duct during the air screening process. This allows the modified additive to be uniformly premixed with the feed grinding material during air conveying, eliminating the need for additional waiting time for mixing. This simplifies the modified feed processing flow and significantly improves production efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a fine grinding device for feed processing, including a grinding equipment platform 1 and a grinding mill 2 for grinding feed raw materials. The grinding mill 2 performs preliminary crushing and grinding of the feed raw materials, processing large pieces of raw materials into powder. The powder is then transported through a discharge port connected to the discharge port 8 of a horizontal air duct 5. The grinding mill 2 is fixed on the table surface of the grinding equipment platform 1. A blower screening mechanism 4 is embedded and fixed on one side of the grinding equipment platform 1. The blower screening mechanism 4 includes a horizontal air duct 5, a blower 7, and an intercepting net 13. The horizontal air duct 5 is embedded and fixed in a groove in the grinding equipment platform 1. The blower 7 is fixed at one end of the horizontal air duct 5, and the intercepting net 13 is fixed on the inner wall of the horizontal air duct 5. The horizontal air duct 5 serves as a channel for wind-driven screening and material conveying, receiving the powder discharged from the grinding mill. The powder is moved by wind power, and the intercepting net 13 helps to separate coarse and fine particles.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that an addition mechanism 9 is provided in front of the blower screening mechanism 4. The addition mechanism 9 includes an additive funnel 10, a metering pump 11, and a feed pipe 12. The addition mechanism 9 precisely controls the amount of additive added. The additive is added synchronously during the wind conveying process through the quantitative delivery of the pump body. Uniform premixing is achieved by utilizing airflow disturbance, which shortens the processing time. The feed pipe 12 is connected and fixed to one side surface of the tilting air duct 6. The metering pump 11 is fixed to the upper end of the feed pipe 12. The additive funnel 10 is fixed to the upper end of the metering pump 11. A discharge port 8 is provided at the docking point of the horizontal air duct 5 and the grinder 2. The discharge port 8 of the horizontal air duct 5 is connected to the discharge port of the grinder 2. The tilting air duct 6 is fixed to one end of the horizontal air duct 5. The lower end of the horizontal air duct 5 is rotatably connected to a tilting block plate 14. A torsion spring 15 is sleeved on the rotating shaft of the tilting block plate 14.

[0023] Further as Figure 4 As shown, it is worth noting that the front end of the grinding equipment platform 1 is provided with an operation port 16, the flipping block plate 14 is rotatably connected in the operation port 16 of the grinding equipment platform 1, one end of the torsion spring 15 is fixed on the end face of the flipping block plate 14, and the other end of the torsion spring 15 is fixed on the wall of the horizontal air duct 5.

[0024] Further as Figure 1 As shown, it is worth noting that a raw material funnel 3 is fixed to the upper part of the back of the grinder 2, and the raw material funnel 3 is connected to the grinder 2.

[0025] The solution has the following working process: Before use, the feed raw materials to be ground are put into the grinder 2 from the raw material funnel 3. After being crushed by the grinding components inside the grinder 2, they are discharged from the discharge port to the horizontal air duct 5. During this process, the airflow generated by the blower 7 can blow the powder falling into the horizontal air duct 5. The interception net 13 set inside the horizontal air duct 5 only allows powder with smaller particle size to pass through. In this way, the wind power conveying and the interception net 13 can intercept the incompletely crushed material, thereby realizing the screening treatment of fine powder and coarse powder.

[0026] During the air screening process, the modified additive inside the additive funnel 10 is quantitatively added to the air duct 5 of the horizontal air duct using the metering pump 11. In this way, the modified additive can be mixed into the feed grinding material during the air conveying process, thereby achieving the purpose of uniform premixing of the feed grinding material with the modified additive when the feed is unloaded by air, which can save the waiting time for modified feed processing.

[0027] After the intercepting net 13 intercepts the coarse material that has not been completely crushed, the flipping block 14 can be pulled down. The flipping block 14 overcomes the torque of the torsion spring 15 and flips down to an inclined state. The inclined flipping block 14 facilitates the discharge of coarse material along the slope to the operating port 16.
