Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed processing technology, specifically a crushing mechanism for fermentation pretreatment of yak feed. Background Technology
[0002] The pulverizing mechanism for yak feed fermentation pretreatment is a device specifically designed for pulverizing yak feed before fermentation. Its function is to break down yak feed raw materials (such as straw, hay, and grains) into smaller particles or powder, making the raw materials more uniform in texture, increasing the contact area with fermentation bacteria, thus facilitating the smooth progress of the subsequent fermentation process, improving fermentation efficiency and feed decomposition, and making the fermented feed more suitable for yak consumption and digestion.
[0003] Traditional feed grinding mechanisms have many shortcomings when processing yak feed. Most existing grinding equipment has a simple tooth structure, often consisting of only simple cylindrical or conical teeth. When dealing with raw materials rich in coarse fiber, such as barley straw and oat grass commonly found in yak feed, this simple tooth structure struggles to penetrate deep into the fibers, failing to efficiently cut and tear them, resulting in insufficient grinding and uneven feed particle size. For example, in some farms using ordinary hammer mills, the ground barley straw still contains long fiber segments, hindering the decomposition of the raw material by microorganisms during subsequent fermentation and negatively impacting the digestibility and absorption by yaks. Utility Model Content
[0004] The purpose of this invention is to provide a crushing mechanism for the fermentation pretreatment of yak feed, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides a crushing mechanism for fermentation pretreatment of yak feed, including a shell, with multiple crushing rollers rotatably arranged inside the shell. Multiple tooth roots are evenly arranged around the circumference of the crushing rollers. Tooth ends and cutting prisms are fixedly installed on the top of the tooth roots. The cutting prisms are installed on the side of the tooth ends, and inclined cutting blades are also installed on the side of the tooth ends. The end of the tooth ends away from the tooth roots is set as a flat cutting edge. Furthermore, the shape of the tooth root is set as a four-cornered frustum that is narrow on the outside and wide on the inside, and the edge of the tooth root is a cutting edge. Furthermore, the circumferential edges of the cutting prism are inclined, and the ends of the cutting prism are set in a pointed cone shape. Furthermore, the number of crushing rollers is four, with two horizontally arranged crushing rollers forming a group. Each crushing roller has a gear at one end, which meshes with another gear adjacent in the horizontal direction. Each crushing roller in the same vertical direction has a drive wheel fixedly installed at its end, and a drive belt connects the two drive wheels. A servo motor is connected to one side of one of the drive wheels. Furthermore, a mounting block is fixedly installed on one side of the housing, and the servo motor is mounted on the mounting block. Furthermore, a protective frame is fixedly installed on the top of the mounting block, and the servo motor is located inside the protective frame. Furthermore, a feed hopper is fixedly installed on the top of the outer shell, and the feed hopper is configured as a funnel shape that is wider at the top and narrower at the bottom. Furthermore, an inclined block is provided below the discharge port of the outer casing, and the inclined block is installed inside the outer casing and located at the bottom of the outer casing.
[0006] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, when in use, the raw material is fed into the hopper, and the servo motor drives multiple sets of crushing rollers to rotate relative to each other through the transmission belt, transmission wheel and gear. The tooth root, tooth end, cutting prism and cutting blade work together to perform squeezing, cutting and tearing operations, and the raw material is fully crushed and discharged through the inclined block. The multi-structure cooperation can crush the raw material from multiple angles, improve the thoroughness and uniformity of crushing, and facilitate subsequent fermentation. The multiple sets of crushing rollers increase the contact area, improve the crushing efficiency and meet the pretreatment requirements.
[0007] 2. In this utility model, a crushing roller is set up and driven by a servo motor through gear meshing and the cooperation of transmission belt and transmission wheel. This allows the two sets of crushing rollers to rotate stably and synchronously relative to each other. This increases the crushing contact area and the number of times the raw materials are crushed, so that the raw materials are subjected to more thorough crushing and cutting between the two sets of crushing rollers, thereby improving the crushing efficiency and effect, and making the raw materials more uniformly crushed to meet the needs of subsequent fermentation pretreatment.

[0010] 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.
[0011] Please see Figures 1-4 This utility model provides a technical solution: See Figures 1-4 As shown, a crushing mechanism for fermentation pretreatment of yak feed includes a shell 1. Multiple crushing rollers 3 are rotatably arranged inside the shell 1. Multiple tooth roots 4 are evenly arranged on the circumference of the crushing rollers 3. Tooth ends 5 and cutting prisms 7 are fixedly installed on the narrow face at the top of the tooth roots 4. The cutting prisms are installed on the side of the tooth ends. Inclined cutting blades 6 are also installed on the side of the tooth ends 5. The end of the tooth ends 5 away from the tooth roots 4 is set as a flat cutting edge.
[0012] When using the yak feed fermentation pretreatment crushing mechanism, the yak feed raw materials are fed into the feed hopper 2. After the raw materials enter the shell 1, the servo motor 11 drives the crushing roller 3 to rotate through the transmission belt 10 and the transmission wheel 9. At the same time, the gears 8 mesh with each other, causing multiple sets of crushing rollers 3 to rotate relative to each other. The tooth root 4, tooth tip 5, cutting prism 7, and cutting blade 6 on the crushing roller 3 work together on the raw materials: the tooth root 4 has a four-cornered truncated pyramid structure that is narrow at the top and wide at the bottom, which uses the cutting edges of the corners to initially squeeze and cut the raw materials; the flat cutting edge of the tooth tip 5 further performs fine cutting on the raw materials, and the side-inclined cutting blade 6 can cut the raw materials from the side; the cutting edge and the pointed tip of the cutting prism 7 can tear and crush the raw materials. The cooperation of multiple parts achieves full crushing of the yak feed raw materials, and the crushed raw materials are guided out by the inclined block 13.
[0013] The multi-structured combination of the tooth root 4, tooth tip 5, cutting blade 6, and cutting prism 7 enables the crushing of yak feed ingredients from different angles and in different ways. Compared with single-structured teeth, it can act on the raw materials more comprehensively, improve the thoroughness of crushing, make the raw material particle size more uniform, and facilitate the full contact between microorganisms and raw materials during subsequent fermentation, thereby improving the fermentation effect. The relative rotation of multiple sets of crushing rollers 3 increases the contact and action area with the raw materials, further improving the crushing efficiency and enabling the raw materials to be processed to the appropriate particle size more quickly, meeting the needs of yak feed fermentation pretreatment.
[0014] See Figure 3 The tooth root 4 is shaped as a four-cornered frustum that is narrow on the outside and wide on the inside, and each corner of the tooth root 4 is provided with a cutting edge.
[0015] The four-cornered frustum shape of the tooth root 4, which is narrow at the top and wide at the bottom, can gradually compress the raw material during the crushing process, avoiding jamming caused by excessive instantaneous force on the raw material. The corners of the frustum are equipped with cutting edges, which can cut the raw material in multiple directions while compressing, increasing the contact and cutting points with the raw material, improving the efficiency of initial crushing, and also enhancing the structural strength of the tooth root 4 itself, reducing wear or deformation during long-term use.
[0016] See Figure 3 The circumferential edges of the cutting prism 7 are inclined, and the ends of the cutting prism 7 are set as pointed cones.
[0017] The cutting blades, angled around the cutting prism 7, generate an oblique cutting force on the feed raw materials when the crushing roller 3 rotates, making it easier to cut into the interior of the raw materials and improving the cutting effect. The pointed cone shape at the end can quickly pierce into harder or coarser raw materials like an awl, breaking them open first, and then further crushing them with the surrounding cutting blades. This can process yak feed raw materials more efficiently, making the raw materials more fully and evenly crushed, which is beneficial for subsequent fermentation.
[0018] See Figure 1 and Figure 4 There are 4 crushing rollers 3. Two crushing rollers 3 are set horizontally as a group. One end of each crushing roller 3 is equipped with a gear 8. The gear 8 meshes with another gear 8 that is adjacent in the horizontal direction. The end of each group of crushing rollers 3 in the same vertical direction is fixedly installed with a transmission wheel 9. A transmission belt 10 is connected between the two transmission wheels 9. A servo motor 11 is connected to one side of one of the transmission wheels 9.
[0019] Four crushing rollers 3 are set up and driven by a servo motor 11 through the meshing of gears 8 and the cooperation of transmission belt 10 and transmission wheel 9. This allows the two sets of crushing rollers 3 to rotate stably and synchronously. The two meshing gears set in the same horizontal direction can rotate relative to each other, so that the two horizontally set crushing rollers 3 rotate relative to each other, that is, in opposite directions. This can increase the crushing contact area and the number of times the raw materials are crushed, so that the raw materials are subjected to more thorough crushing and cutting between the two sets of crushing rollers 3, thereby improving the crushing efficiency and effect, and making the raw materials more uniformly crushed to meet the needs of subsequent fermentation pretreatment.
[0020] See Figure 1 A mounting block 12 is fixedly installed on one side of the outer casing 1, and a servo motor 11 is mounted on the mounting block 12.
[0021] The servo motor 11 is mounted on the mounting block 12, which provides a stable mounting position for the servo motor 11, so that the servo motor 11 remains stable during operation, reducing the impact of vibration on itself and the connection with components such as the transmission wheel 9 and the transmission belt 10, thereby ensuring the stability of power transmission, allowing the crushing roller 3 to rotate continuously and stably, and improving the reliability of the crushing mechanism.
[0022] See Figure 4 A protective frame is fixedly installed on the top of the mounting block 12, and the servo motor is located inside the protective frame.
[0023] The protective frame on the top of the mounting block 12 is set outside the servo motor 11, which can prevent external dust, debris and other foreign objects from entering the servo motor 11, reducing interference with the operation of the motor. At the same time, it can prevent operators from accidentally contacting the rotating parts of the servo motor 11 during equipment operation, reducing safety hazards. It can also reduce the impact of external collisions on the servo motor 11 to a certain extent, protecting the motor from damage.
[0024] See Figure 1 The top of the outer shell 1 is fixedly installed with a feed hopper 2, which is configured as a funnel shape that is wider at the top and narrower at the bottom.
[0025] The feed hopper 2 at the top of the outer shell 1 is designed as a funnel shape that is wider at the top and narrower at the bottom. The wider opening at the top allows operators to put in a larger amount of yak feed raw materials at once, reducing the trouble of frequent feeding. The narrower outlet at the bottom guides the raw materials into the crushing area inside the outer shell 1, preventing the raw materials from scattering or piling up on the top of the outer shell 1, ensuring that the raw materials can smoothly enter the crushing roller 3 for crushing, and improving the convenience and efficiency of feeding.
[0026] See Figure 1 An inclined block 13 is provided below the discharge port of the outer casing 1. The inclined block 13 is installed inside the outer casing 1 and is located at the bottom of the outer casing.
[0027] The inclined block 13 at the bottom of the inner shell 1 is located below the discharge port. It can guide the crushed feed raw materials to slide towards the outlet by its own inclined angle, avoid the raw materials from accumulating at the bottom of the outer shell 1, ensure that the crushed materials can be discharged smoothly, reduce residue, and at the same time reduce the difficulty of cleaning the inside of the outer shell 1, making the whole crushing process more continuous.
[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
