Description

Technical Field

[0001] This utility model relates to the technical field of feed grinding devices, specifically to a grinding device for feed production. Background Technology

[0002] Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed mainly refers to the food consumed by animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed ingredients, such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. The processing and production of feed involves...

[0003] Chinese Patent Application No. CN202021440888.8 discloses a grinding device for feed production, including a grinding box with a crushing chamber and a grinding chamber arranged at the top and bottom respectively inside the grinding box. A crushing component is installed in the crushing chamber, and a first funnel communicating with the grinding chamber is provided at the bottom of the crushing chamber. This utility model achieves heating, drying, and crushing of feed raw materials through the cooperation of a resistance heating plate and the crushing component, which facilitates the subsequent grinding of feed raw materials. By rotating the screw, the distance between the two sets of grinding wheels can be adjusted, thereby achieving the grinding of feed raw materials of different particle sizes. By setting four feeding hoppers, different feed raw materials can be mixed and ground simultaneously, reducing the need for subsequent re-mixing of different single feed raw materials and simplifying the process. At the same time, a fan assembly can separate the ground feed raw materials, making it easier to grind larger feed raw materials again, thereby improving the uniformity of the particle size after grinding.

[0004] However, the following problems still exist: during the feed grinding process, as the feed is ground finely, a small portion of the feed may get stuck during the discharge process, which may eventually lead to accumulation and clumping, adversely affecting the overall processing efficiency.

[0026] Example

[0027] The grinding apparatus provided in this embodiment, such as Figures 1-3 As shown, it includes: a feed raw material grinding mechanism, a receiving mechanism 11, and an auxiliary discharging mechanism.

[0028] The feed raw material grinding mechanism includes a discharge box 1, an end cover 2, a mounting frame 3, a grinding tank 4, and a drive motor 6. The end cover 2 is bolted to the top of the discharge box 1. The mounting frame 3 is welded to the surface of the end cover 2. The drive motor 6 is bolted to the surface of the mounting frame 3. The output end of the drive motor 6 is connected to the grinding roller 7 via a coupling. The end of the grinding roller 7 passes through the mounting frame 3 via a bearing and is located inside the grinding tank 4. The bottom of the grinding tank 4 is connected to the discharge box 1 via a solenoid valve.

[0029] The receiving mechanism 11 includes a receiving plate 111, a baffle 112 and a chute 113. The receiving plate 111 is provided with baffles 112 on both sides and the receiving plate 111 is slidably installed on the inner wall surface of the discharge box 1.

[0030] The auxiliary discharge mechanism includes a first connecting plate 12, a second connecting plate 13, a transmission gear 14, a stepper motor 15, a push rod 16, and a pressure spring 18. The first connecting plate 12 is bolted to one side surface of the discharge box 1. A transmission shaft is mounted on the first connecting plate 12 via bearings. The stepper motor 15 is assembled to the surface of the first connecting plate 12. The output end of the stepper motor 15 is connected to the end of the transmission shaft via a coupling. The transmission gear 14 is keyed to the surface of the transmission shaft. The push rod 16 is slidably mounted to one side surface of the discharge box 1 via linear bearings. A rack 17 is mounted on the end of the push rod 16, and the rack 17 meshes with the transmission gear 14. The other end of the push rod 16 is connected to the receiving plate 111.

[0031] In the grinding device employing the above technical solution, auxiliary supports 5 are uniformly welded sequentially onto the surface of the grinding jar 4. The ends of the auxiliary supports 5 are welded and fixed to the end cap 2. Both the auxiliary supports 5 and the mounting frame 3 are integrated structures made of steel. The auxiliary supports 5, in conjunction with the top mounting frame 3, stabilize the overall structure of the grinding jar 4, effectively preventing external impacts from affecting the overall structural safety.

[0032] Specifically, in this embodiment, fixing frames 8 are welded to both sides of the discharge box 1, and support plates are welded between the fixing frames 8. The fixing frames 8 provide basic support and protection, and the support plates welded between the fixing frames 8 enable them to be connected, preventing unnecessary damage from occurring easily.

[0033] The inner wall of the discharge box 1 is equipped with a guide rail 10, and the surfaces of the baffles 112 on both sides of the receiving plate 111 are provided with sliding grooves 113. The receiving plate 111 is slidably installed onto the surface of the guide rail 10 through the sliding grooves 113. The structure of the guide rail 10 allows the receiving plate 111 to be slidably installed. When the receiving plate 111 is driven by an external force, it can move relatively regularly along the guide rail 10, thereby continuously receiving and discharging materials.

[0034] A second connecting plate 13 is bolted to one side surface of the discharge box 1. The surface of the second connecting plate 13 is movably connected to the end of the drive shaft through a bearing. The addition of another connecting plate provides further support to the drive shaft, enabling it to have good stability and safety, and ensuring overall safety when driven and controlled by the stepper motor 15.

[0035] A pressure spring 18 is sleeved on the surface of the push rod 16. The two ends of the pressure spring 18 are fixedly connected to the inner wall of the discharge box 1 and the surface of the receiving plate 111, respectively. The pressure spring 18 provides a certain auxiliary protection effect and can provide a certain auxiliary elastic force when the receiving plate 111 is driven to slide horizontally, which is conducive to the continuous sliding in and out of the receiving plate 111, and the overall movement is smoother.

[0036] In summary, the grinding apparatus provided in this embodiment has the following advantages:

[0037] In the specific working process, the raw materials to be ground are fed into the grinding tank 4. The grinding roller 7 is controlled by the drive motor 6 to grind the raw materials thoroughly. The ground feed is then fed into the discharge box 1 using a solenoid valve. The feed falls onto the surface of the receiving plate 111. At this time, the stepper motor 15 is started, which drives the transmission shaft and the transmission gear 14 to rotate continuously and evenly back and forth. The operator sets the stepper motor 15 to rotate the transmission gear 14 one-quarter of the way before returning to its starting position. This repetitive motion avoids excessive rotation that could affect the pushing effect. In this way, the transmission gear 14 and the rack 17 work together to continuously push and pull the push rod 16, ultimately causing the push rod 16 to perform a sufficient and continuous push and pull operation on the receiving plate 111, thus completing the auxiliary discharge action. This coordinated action ensures that the feed is fully shaken before being discharged, effectively preventing the feed from accumulating and clumping, and ensuring overall processing efficiency.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
