[0002] A dry-wet mixer for feed processing is a mechanical device that mixes dry and wet feed. This equipment is widely used in feed processing plants, farms, and other places where feed mixing is required. Traditional dry-wet mixers used for animal feed production remove all the feed from the mixing tank after mixing. However, due to various reasons, the output is often too large after removing all the mixed feed, resulting in waste. Furthermore, the mixed feed will absorb moisture from the air, reducing its nutritional value and making it less effective for animals to consume, thus failing to meet their nutritional needs.

[0003] A search revealed existing technology (application number: CN202420240137.3), which describes a "dry and wet mixer for animal feed production." This utility model includes a mixing tank, with a water inlet pipe fixedly installed at the top, a discharge cylinder fixedly installed on the right side surface of the mixing tank, and a discharge pipe fixedly installed at the bottom of the discharge cylinder; a motor fixedly installed on the right side of the discharge cylinder, with a rotating rod fixedly installed on the output shaft of the motor, the rotating rod located inside the discharge cylinder, and spiral blades fixedly installed on the surface of the rotating rod; this utility model, through the configuration of a control device, discharges high-quality feed through the gaps between the spiral blades.

[0028] 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.

[0029] Reference Figures 1-4 This utility model provides a crushing and grinding device for animal feed production, comprising: a crusher housing assembly 1, a raw material inlet 11 above the crusher housing assembly 1, a feed crushing structure assembly 2 below the raw material inlet 11, a fastening structure assembly 3 on the crusher housing assembly 1, a screening plate 4 below the feed crushing structure assembly 2, a stirring blade 14 below the screening plate 4, a motor 13 below the stirring blade 14, an auxiliary material inlet 12 on the outer side of the crusher housing assembly 1, a discharge port 15 on the side of the crusher housing assembly 1 away from the auxiliary material inlet 12, and a valve 16 above the discharge port 15; the crusher housing... A motor 21 is installed on the outside of the assembly 1. The output end of the auxiliary material inlet 12 is connected to a rotating shaft. A gear 23 is installed on the rotating shaft. A gear 22 is installed on one side of the gear 23. The rotating shaft passes through and rotates to connect the crusher housing assembly 1. A baffle 24 is installed on the crusher housing assembly 1. A crushing wheel 25 is installed on the rotating shaft located inside the crusher housing assembly 1. A spring 31 is installed inside the outside of the crusher housing assembly 1. A snap-on end 32 is installed below the spring 31. A hinge 33 is installed below the snap-on end 32. A screen plate slot 36 is installed on the side of the screening plate 4 near the hinge 33. A screen plate pushing end 35 is installed on the side of the screen plate slot 36 near the hinge 33.

[0030] In this embodiment, the crusher housing assembly, the feed crushing structure assembly, and the fastening structure assembly constitute the crushing and grinding device for animal feed production involved in this application, realizing a crushing and grinding device for animal feed production. The material in this application is animal feed, and any feed raw material that only needs to be crushed and ground can be used in this equipment. This application does not limit the specific material category.

[0031] In this embodiment, when the screening buckle plate 4 is pushed, the screen plate pushing end 35 abuts against the inclined surface on one side of the buckle engaging end 34. This action will press down the buckle pressing end 32 until the buckle engaging end 34 is engaged in the screen plate slot 36, thereby locking the screening buckle plate 4, achieving overall stability and preventing it from falling off during screening.

[0032] In this embodiment, the screening plate 4 is located below the crushing structure group 2 and is used to screen the crushed material to separate materials of different particle sizes.

[0033] It should be noted that the screening panel is made of aluminum alloy. Aluminum alloy has good durability and stability, can maintain a good appearance and performance for a long time, and has good oxidation resistance, making it suitable for applications that are exposed to air for a long time.

[0034] Specifically, gear 1 22 is meshed with gear 2 23. There are two sets of rotating shafts that are parallel to each other. Motor 2 21 is connected to the rotating shaft where gear 2 23 is located. Crushing wheels 25 are respectively installed on the two sets of rotating shafts. Motor 2 21 drives the rotating shaft to rotate, which in turn drives gear 2 23 to rotate. Gear 2 23 drives gear 1 22 to rotate. The two sets of crushing wheels 25 rotate in opposite directions to crush and pulverize the raw materials.

[0035] In this embodiment, since the two sets of crushing wheels 25 rotate in opposite directions, the raw material is subjected to greater shear force and crushing pressure in the crushing chamber, which significantly improves the crushing efficiency. The counter-rotating crushing wheels 25 ensure that the raw material is subjected to uniform force throughout the crushing chamber, thereby obtaining a more uniform crushing effect and improving the quality of the feed.

[0036] Specifically, baffles 24 are provided on the inner wall of the crusher housing assembly 1, and multiple sets are provided. The baffles 24 mesh with the crushing wheel 25 to ensure the uniformity of the raw material when it is crushed and to prevent uncrushed raw material from falling from the edge of the crushing wheel 25.

[0037] As a preferred implementation, the baffle 24 meshes with the crushing wheel 25. This design allows the raw material to be subjected to a more uniform force during the crushing process because the baffle 24 can prevent the raw material from passing directly through the gap of the crushing wheel 25, forcing the raw material to rub and crush fully between the two crushing wheels, thereby improving the uniformity of crushing.

[0038] Specifically, spring 31 is set in a groove opened in the inner wall of the crusher housing assembly 1, and both ends of spring 31 are connected to the inner wall of the groove and the top of the snap-on end 32. Hinge 33 is fixed on the crusher housing assembly 1. Snap-on end 32 rotates on hinge 33. Snap-on end 34 is provided on the side of snap-on end 32 near the screen plate slot 36. Snap-on end 34 engages with screen plate slot 36 to fix the screening plate 4. When the screening plate 4 is pushed, the screen plate pushing end 35 abuts against the inclined surface on one side of snap-on end 34 and presses down snap-on end 32 until snap-on end 34 engages in screen plate slot 36.

[0039] It should be noted that the snap-fit ​​design between the snap-fit ​​end 34 and the screen plate slot 36 ensures the stability of the screening plate 4 during the crushing process, prevents the screen plate from shifting due to vibration, and ensures the consistency of screening effect. By quickly replacing the screening plates 4 with different apertures, the equipment can adapt to the screening needs of different feed raw materials, improving the flexibility and adaptability of the equipment.

[0040] Specifically, the screening plate 4 is provided with small holes. The screening plate 4 screens the powder after it is crushed by the feed crushing structure group 2. The end of the screening plate 4 that passes through the crusher housing group 1 is provided with a handle, which makes it easy to replace the screening plate 4 according to the required feed size.

[0041] As a preferred implementation method, screening the pulverized powder by using the screening plate 4 can ensure that the feed particles are of appropriate size, increase the feed surface area, facilitate animal digestion and absorption, and improve feed utilization. The screening plate 4 is equipped with a handle at one end of the pulverizer housing assembly 1. This design allows the operator to easily replace the screen plate to adapt to the screening requirements of different feed raw materials, thereby improving the flexibility of the equipment and the convenience of operation.

[0042] Specifically, the auxiliary material inlet 12 is used for adding feed auxiliary materials, and the output end of the motor 13 is connected to the stirring blade 14. The motor 13 drives the stirring blade 14 to fully mix the powder and auxiliary materials.

[0043] It should be noted that the high-efficiency driving capability of motor 13 enables the stirring blades 14 to quickly mix a large amount of materials, shortening the production cycle and improving the overall production efficiency.

[0044] Specifically, valve 16 is located at the outlet of discharge port 15. After valve 16 is opened, the mixed powder and auxiliary materials are discharged from discharge port 15.

[0045] In this embodiment, valve 16 is located at the outlet of discharge port 15, which can precisely control the discharge of mixed powder and auxiliary materials, ensuring continuous production and supply of feed. By controlling valve 16, it can be ensured that the feed is discharged evenly after mixing, avoiding feed quality differences caused by uneven mixing and improving the overall quality of feed.

[0046] Before crushing, replace the screening plate 4 according to the required feed size and insert the appropriate screening plate 4 into the crusher housing assembly 1. At this time, the screen plate pushing end 35 pushes against the locking end 34, the spring 31 is compressed, and the locking end 34 rotates counterclockwise around the hinge 33. When the fastening structure assembly 3 is pushed to the bottom, the spring 31 extends, the locking end 34 rotates clockwise around the hinge 33, and the locking end 34 falls into the screen plate slot 36 and locks in place. After the screen is placed, pour the feed raw materials into the raw material inlet 11. The motor 21 starts, driving the gear 22 to rotate, which in turn drives the gear 23 meshing with it to rotate synchronously. At this time, the two sets of crushing wheels 25 arranged in the crusher housing assembly 1 rotate in opposite directions to crush the raw materials. The powder falls after being screened by the screening plate 4. At the same time, feed additives are added through the additive inlet 12. The motor 13 is started, and the stirring blades 14 begin to rotate and stir the powder and additives. After thorough mixing, open valve 16, and the feed will be discharged from discharge port 15. Design advantages: The equipment's screen plate is fixed and easy to replace; operation is simple; installation is easy; and it can effectively mix feed.

[0047] This utility model discloses a crushing and grinding device for animal feed production. This device allows users to quickly change the screening plate 4 according to the feed size requirements, improving production flexibility and efficiency. The synergistic effect of the screen plate pushing end 35 and the snap-fit ​​end 34 simplifies the fixing and replacement process of the screen plate, making operation simpler and faster. The compression and extension mechanism of the spring 31 ensures the stability of the screen plate during the crushing process and reduces the risk of displacement of the screen plate in high vibration environments. The counter-rotation design of the two sets of crushing wheels 25 improves the crushing efficiency, enabling the raw materials to be crushed quickly and evenly. The rotation of the stirring blades 14 ensures the full mixing of powder and auxiliary materials, improving the nutritional uniformity and digestibility of the feed.

[0048] Finally, it should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
