Description

Technical Field

[0001] This application relates to the field of feed processing equipment, specifically a feed fine pulverizer. Background Technology

[0002] In industries such as animal husbandry, feed quality directly affects animal growth, development, and production performance. Finely ground feed can improve feed digestibility, reduce waste, and increase farming efficiency. Traditional feed grinders typically use hammer mills or toothed claw mills, which are simple in structure and easy to operate. However, this traditional method has the following drawbacks: uneven grinding effect, difficulty in controlling fineness, resulting in inconsistent feed particle size, affecting feed digestibility, and requiring subsequent screening before utilization. Utility Model Content

[0003] The purpose of this utility model is to provide a feed fine pulverizer to solve the problems of uneven pulverization effect, difficulty in controlling fineness, and the need for subsequent screening before utilization in existing traditional feed pulverizers. To achieve the above objective, this application provides the following technical solution: a feed fine pulverizer, comprising:

[0004] Mounting rack;

[0005] The housing is disposed on the mounting frame, with a feed inlet at the top and a hammer rotor inside. The side wall is provided with a shaft hole and a bearing seat. A drive shaft is installed in the bearing seat and is coupled to the hammer rotor to drive the hammer rotor to rotate.

[0006] A sieve plate is disposed inside the housing and located directly below the hammer rotor assembly;

[0007] A conveying pipe is provided at the bottom of the housing and is connected to the interior of the housing. An auger shaft is provided inside the conveying pipe.

[0008] A blower, which is connected to the conveying pipe, is used to receive and discharge the feed conveyed by the auger shaft. The impeller shaft inside the blower passes through the blower housing and is connected to the mounting frame.

[0009] A drive mechanism, mounted on the mounting bracket, includes a first pulley mechanism, a second pulley mechanism, a third pulley mechanism, and a motor. The first pulley mechanism is connected to the drive shaft and the motor, and is used to transmit the power of the motor to the drive shaft. The second pulley mechanism is connected to the drive shaft and the auger shaft, and is used to transmit the rotation of the drive shaft to the auger shaft. The third pulley mechanism is connected to the impeller shaft and the drive shaft, and is used to transmit the power of the drive shaft to the impeller shaft.

[0010] In a preferred embodiment of this technical solution, the hammer rotor includes at least three support plates, and a connecting shaft connects two adjacent support plates, with hammers sleeved on the connecting shaft.

[0011] In a preferred embodiment of this technical solution, the support plate is circular, and the connecting shafts are evenly distributed along the circumference of the support plate.

[0012] In a preferred embodiment of this technical solution, at least three connecting shafts are provided.

[0013] In a preferred embodiment of this technical solution, the sieve plate and the housing are detachably connected.

[0015] In a preferred embodiment of this technical solution, the auger shaft is arranged parallel to the drive shaft.

[0016] In a preferred embodiment, the present technical solution further includes a pallet, which is disposed at the bottom of the feed inlet.

[0017] In a preferred embodiment of this technical solution, the pallet is U-shaped, with its bottom connected to the bottom plate of the feed inlet and its sidewalls connected to the side plate of the feed inlet.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] By incorporating a hammer rotor and a sieve plate, the hammer rotor rotates at high speed driven by the drive shaft, finely pulverizing the feed. The sieve plate, located directly below the hammer rotor, filters out feed that meets the required pulverization standards, ensuring uniform feed particle size. When feed accumulates to a certain height on the sieve plate, it is drawn back into the hammer rotor for further pulverization, solving the problem of uneven pulverization in traditional feed grinders. The pulverized feed is directly conveyed to the blower through the auger shaft in the conveying pipe, and then discharged to a designated location by the blower, eliminating the need for subsequent screening operations, simplifying the production process and improving efficiency. The drive mechanism uses multiple pulleys to transmit motor power to the drive shaft, auger shaft, and impeller shaft, ensuring high power transmission efficiency, stable and reliable operation, and guaranteeing normal equipment operation and pulverization effect.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0031] In order to solve the technical problems in the background art, such as Figure 1-6As shown, this application provides a technical solution: a feed fine pulverizer, characterized as follows:

[0032] Mounting frame 1 is the basic structure of the entire feed fine pulverizer, typically made of robust metal materials such as carbon steel or stainless steel to ensure the stability and durability of the equipment. Mounting frame 1 has multiple mounting positions for fixing components such as the housing 2, fan 11, and drive mechanism 13. Housing 2, mounted on mounting frame 1, is the main working chamber of the feed fine pulverizer. The upper part of housing 2 has a feed inlet 3 for receiving feed raw materials. Inside housing 2 is a hammer rotor 4, composed of multiple hammers evenly distributed on drive shaft 7, used for fine pulverizing the feed. The side wall of housing 2 has shaft holes 5 and bearing seats 6. Drive shaft 7 is installed in bearing seats 6 and coupled to hammer rotor 4 to drive its rotation. Housing 2 also has a sieve plate 8, located directly below hammer rotor 4, for screening the pulverized feed. The sieve plate 8 completes the screening process through the feed's own gravity combined with the vibration of the rotating hammer rotor 4. A conveying pipe 9 is located at the bottom of the housing 2 and is connected to the interior of the housing 2. It is used to convey the crushed feed to the blower 11. An auger shaft 10 is installed inside the conveying pipe 9. The auger shaft 10 is driven by a drive mechanism 13 and is used to convey the crushed feed from the bottom of the housing 2 to the blower 11. The auger shaft 10 is arranged parallel to the drive shaft 7 to ensure smooth and stable feed conveying. The blower 11 is connected to the conveying pipe 9 and is used to receive and discharge the feed conveyed by the auger shaft 10. The impeller shaft 12 inside the blower 11 passes through the blower 11 housing and is connected to the mounting bracket 1 via a bearing base to ensure stable operation of the blower 11. The blower 11 can discharge feed from the conveying pipe 9 to a designated location, realizing continuous feed production and conveying. The drive mechanism 13 includes a first pulley mechanism 14, a second pulley mechanism 15, a third pulley mechanism 16, and a motor 17. The first pulley mechanism 14 is connected to the drive shaft 7 and the motor 17, and is used to transmit the power of the motor 17 to the drive shaft 7, driving the hammer rotor 4 to rotate, thereby crushing the feed. The second pulley mechanism 15 is connected to the drive shaft 7 and the auger shaft 10, and is used to transmit the rotation of the drive shaft 7 to the auger shaft 10, driving the auger shaft 10 to rotate, thereby conveying the feed. The third pulley mechanism 16 is connected to the impeller shaft 12 and the drive shaft 7, and is used to transmit the power of the drive shaft 7 to the impeller shaft 12, driving the fan 11 to run. The motor 17 is usually a variable frequency speed control type, which can adjust the speed according to the crushing requirements to achieve energy-saving operation and fine crushing.

[0033] In operation, feed ingredients are added through inlet 3 and enter the housing 2. Motor 17 drives drive shaft 7 to rotate via first pulley mechanism 14. Drive shaft 7 drives hammer rotor 4 to rotate at high speed, finely pulverizing the feed. The pulverized feed is screened through sieve plate 8, and qualified feed particles fall into conveying pipe 9. Drive shaft 7 drives auger shaft 10 to rotate via second pulley mechanism 15. Auger shaft 10 conveys the feed from conveying pipe 9 to blower 11. Drive shaft 7 drives impeller shaft 12 to rotate via third pulley mechanism 16. Blower 11 discharges the feed from conveying pipe 9 to a designated location, completing the feed pulverization and conveying process.

[0034] Furthermore, the hammer rotor 4 includes at least three support plates 18, which are made of high-strength steel and possess good strength and rigidity. The support plates 18 are arranged sequentially along the axial direction of the drive shaft 7, with a certain distance maintained between adjacent support plates 18 to ensure sufficient space for hammer installation and rotation. A connecting shaft 19, typically cylindrical, connects adjacent support plates 18. Both ends of the connecting shaft 19 are fixed to the adjacent support plates 18, ensuring the stability and integrity of the connection between the support plates 18. Hammers, typically elongated or square, are fitted onto the connecting shaft 19 and are made of high-strength wear-resistant steel. The hammers are fixed to the connecting shaft 19 by bolts or snap rings to prevent loosening during high-speed rotation. The number of hammers is designed according to the crushing requirements and the size of the hammer rotor 4, and is typically multiple, evenly distributed on the connecting shaft 19 to achieve uniform crushing of the feed.

[0035] Furthermore, the support plate 18 of the hammer rotor 4 is circular, a design that makes the structure of the hammer rotor 4 more compact and balanced. The connecting shaft 19 is evenly arranged along the circumference of the support plate 18, ensuring the uniform distribution and balance of the hammers during rotation. The circular design of the support plate 18 allows the hammer rotor 4 to maintain good balance during high-speed rotation, reducing vibration and wear caused by imbalance. The even arrangement of the connecting shaft 19 along the circumference of the support plate 18 allows the hammers to evenly strike the feed during rotation, improving the uniformity of the crushing effect.

[0036] Furthermore, there are at least three connecting shafts 19, evenly distributed along the circumference of the support plate 18. This design ensures the structural stability of the hammer rotor 4 during high-speed rotation. Multiple connecting shafts 19 can evenly distribute the weight of the hammers and the centrifugal force generated by rotation, reducing the risk of deformation or breakage caused by excessive force on a single connecting shaft 19, thereby improving the overall strength and durability of the hammer rotor 4.

[0037] Furthermore, the detachable connection between the sieve plate 8 and the housing 2 can be achieved in various ways, such as bolt connection, snap-fit ​​connection, or flange connection. These connection methods are not only convenient to install but also quick to disassemble, facilitating the replacement and cleaning of the sieve plate 8. The sieve plate 8 is typically circular or square, with its edges featuring connection structures that match the inner wall of the housing 2. For example, the edges of the sieve plate 8 can be equipped with flanges or grooves, which cooperate with the corresponding structures on the inner wall of the housing 2 to ensure the stability and sealing of the sieve plate 8 during use. Depending on different feed raw materials and grinding requirements, sieve plates 8 with different aperture sizes can be replaced, thereby controlling the fineness of the ground feed. This design makes the feed fine grinder more adaptable and flexible.

[0038] Furthermore, the access port 20 is located at the bottom of the side wall of the housing 2, and its position is designed to allow operators to easily perform internal inspections and maintenance. The shape of the access port 20 is adapted to the shape of the screen plate 8, and is usually square, to ensure that the screen plate 8 can be easily removed from the access port 20 when it needs to be replaced or cleaned.

[0039] Furthermore, the auger shaft 10 is located inside the conveying pipe 9, arranged parallel to the drive shaft 7 inside the housing 2. This parallel arrangement ensures that the auger shaft 10 and the drive shaft 7 are spatially independent, avoiding mutual interference and ensuring their normal operation. The auger shaft 10 is connected to the drive shaft 7 via a second pulley mechanism 15. Power is transmitted from the drive shaft 7 to the auger shaft 10, driving it to rotate and thus conveying the feed. The parallel arrangement of the auger shaft 10 and the drive shaft 7 makes power transmission more direct and efficient. The drive shaft 7 transmits power to the auger shaft 10 via a pulley mechanism; this transmission method is simple and reliable, reducing energy loss during power transmission. The parallel arrangement also makes the installation and adjustment of the pulley mechanism more convenient, improving the maintainability and reliability of the equipment.

[0040] Furthermore, the pallet 21 is located at the bottom of the feed inlet 3 and is directly connected to the feed inlet 3. The main function of the pallet 21 is to support the feed material to be fed into the feed inlet 3 and guide it evenly to the working area of ​​the hammer rotor 4. The design of the pallet 21 can prevent the feed material from accumulating or clogging at the bottom of the feed inlet 3, ensuring that the feed material can smoothly enter the crushing area.

[0041] Furthermore, the pallet 21 adopts a U-shaped structure, with its bottom fixedly connected to the bottom plate of the feed inlet 3 via welding, bolting, or integral casting, ensuring that the pallet 21 can stably support the feed ingredients during use. The side walls of the pallet 21 are also fixedly connected to the side plates of the feed inlet 3 in a similar manner, forming an integral structure. This connection method not only ensures the stability of the pallet 21 but also makes the connection between the pallet 21 and the feed inlet 3 more robust and reliable. The U-shaped structure design gives the pallet 21 a certain depth, allowing it to hold more feed ingredients and preventing feed from scattering or clogging during feeding.
