Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a distiller's grains crushing mechanism for feed processing. Background Technology

[0002] Distillers' grains (DGD) are a high-protein, high-energy, high-fiber, and high-mineral feed ingredient. They can be used directly as a feed additive to provide rich nutrients for livestock such as pigs, chickens, cattle, and sheep. Pigs fed with DGD as a feed additive show a significant increase in vitamin E content in their pork, which helps slow down fat oxidation during storage. However, DGD typically has a large, lumpy structure with uneven particle size. Direct use in feed production can not only affect the uniformity of feed mixing and reduce feed quality, but may also lead to increased wear and tear on subsequent processing equipment, increasing production costs. Therefore, crushing DGD is an indispensable step in feed processing. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a grains crushing mechanism for feed processing, which can effectively crush grains by setting up an agglomerating hopper and a crushing cone.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a feed processing distillers' grains crushing mechanism, comprising:

[0005] The crushing chamber has an inlet and an outlet at its top and bottom, respectively.

[0006] An aggregating hopper is fixed inside the crushing chamber, and a discharge hole is provided at the center of the bottom of the aggregating hopper;

[0007] A crushing cone is rotatably installed inside the crushing chamber and located above the gathering hopper, with the distance between the crushing cone and the gathering hopper gradually decreasing from top to bottom;

[0008] The motor is fixed to the crushing chamber;

[0009] A feeding device is installed on the crushing cone. When the motor drives the crushing cone to rotate, the feeding device pushes the raw materials of distiller's grains into the gap between the gathering hopper and the crushing cone.

[0010] Preferably, a main shaft is rotatably mounted in the crushing chamber, the motor is used to drive the main shaft to rotate, the crushing cone is fixed on the main shaft, and the axis of the crushing cone coincides with the axis of the main shaft.

[0011] Preferably, the feeding device includes:

[0012] A rotating sleeve is fitted onto the main shaft of the crushing cone on the side away from the material discharge hole, and a connecting frame is fixed on the rotating sleeve;

[0013] A feeding disc, which is rotatably mounted on a connecting frame, and the axis of the feeding disc is offset from the axis of the crushing cone;

[0014] A transmission assembly is disposed between the main shaft and the rotating sleeve. When the motor drives the main shaft to rotate, the main shaft drives the rotating sleeve to rotate through the transmission assembly.

[0015] Preferably, the transmission assembly includes:

[0016] A transmission box is fixed inside the crushing chamber above the crushing cone, and the main shaft passes through the transmission box;

[0017] A secondary shaft is rotatably mounted inside a transmission box. A first gear and a second gear are fixed on the secondary shaft. A third gear located inside the transmission box is fixed on the main shaft. A fourth gear located inside the transmission box is fixed on the rotating sleeve.

[0018] The third gear meshes with the first gear, and the second gear meshes with the fourth gear.

[0019] Preferably, there are two material feeding discs, which are symmetrically arranged on the connecting frames on both sides of the rotating sleeve.

[0020] Preferably, the crushing chamber above the gathering hopper is provided with a splash guard section. The inner diameter of the splash guard section is smaller at the top and larger at the bottom. The side wall of the feeding disc is a conical surface. The conical surface cooperates with the splash guard section to push the wine tank into the gap between the downward gathering hopper and the crushing cone.

[0021] Preferably, a screen is provided in the crushing chamber between the material discharge hole and the material outlet, and the main shaft passes through the center of the screen.

[0022] Preferably, a sliding sleeve is fitted on the main shaft, the sliding sleeve is keyed to the main shaft, and a cleaning brush for unblocking the screen is fixed on the sliding sleeve.

[0024] Preferably, the crushing cone is provided with a plurality of material-pushing blades on its conical surface. When the crushing cone rotates, the material-pushing blades push the lees in the gap between the collecting hopper and the crushing cone downwards.

[0025] The beneficial effects of this utility model are as follows:

[0026] The crushing cone of this invention is rotatably installed inside the crushing chamber and located above the gathering hopper, with the distance between them gradually decreasing from top to bottom. This causes the raw materials of distiller's grains to continuously gather towards the gap between the gathering hopper and the crushing cone under the action of gravity and the feeding device. As the gap gradually narrows, the distiller's grains are subjected to stronger compression and shearing forces, thus being crushed more effectively and improving crushing efficiency. The feeding disc is rotatably installed on the connecting frame, and the axis of the feeding disc is offset from the axis of the crushing cone. This allows the rotating feeding disc to more effectively push the raw materials of distiller's grains from the top of the crushing cone to the gap between the gathering hopper and the crushing cone, improving the pushing and crushing effect of the raw materials. A screen is installed in the crushing chamber between the discharge hole and the outlet to screen the crushed distiller's grains, ensuring that the distiller's grains that meet the particle size requirements pass through the screen and enter the outlet. During the rotation of the main shaft, the cleaning brush also rotates to clean the screen, preventing screen blockage, ensuring smooth screening, and improving the continuous working capacity of the equipment.

[0036] 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.

[0037] Example 1:

[0038] like Figures 1 to 6 As shown, Embodiment 1 of this utility model proposes a feed processing distillers' grains crushing mechanism, mainly including a crushing chamber 1, a gathering hopper 4, a crushing cone 6, a motor 7, and a feeding device. The crushing chamber 1 is cylindrical in shape, with an inlet 2 and an outlet 3 at its top and bottom, respectively, for the entry of distillers' grains raw materials and the discharge of crushed materials. Four support legs are fixed to the bottom of the outer shell of the crushing chamber 1. Figure 3 As shown, the collecting hopper 4 is fixed inside the crushing chamber 1, and a discharge hole 5 is provided at the center of its bottom, allowing the crushed lees to fall smoothly into the lower part. A main shaft 8 is rotatably installed inside the crushing chamber 1, and a crushing cone 6 is fixed on the main shaft 8 and located above the collecting hopper 4. The distance between the outer wall of the crushing cone 6 and the inner wall of the collecting hopper 4 gradually decreases from top to bottom. This causes the lees to gradually gather towards the gap under the action of gravity and the feeding device, and be subjected to stronger compression and shearing forces, thereby achieving efficient crushing.

[0039] Motor 7 is fixed to the top of crushing chamber 1, providing power to the entire crushing mechanism. The material feeding device is mounted on crushing cone 6. (Example:) Figure 3As shown, motor 7 is a geared motor. The output shaft of motor 7 is connected to the main shaft 8, driving the main shaft 8 to rotate. The axis of the crushing cone 6 coincides with the axis of the main shaft 8, ensuring the stable rotation of the crushing cone 6. Since the lees entering the crushing chamber 1 from the feed inlet 2 will fall to the top of the crushing chamber 1, in order to actively push the lees into the gap between the collecting hopper 4 and the crushing cone 6, the feeding device designed in this utility model includes a rotating sleeve 9, a feeding disc 11, and a transmission assembly. The rotating sleeve 9 is sleeved on the main shaft 8 on the side of the crushing cone 6 away from the discharge hole 5. A bearing is provided between the rotating sleeve 9 and the main shaft 8, so the rotating sleeve 9 can rotate on the main shaft 8. A connecting frame 10 is fixed on the rotating sleeve 9. The feeding disc 11 is rotatably mounted on the connecting frame 10, and the axis of the feeding disc 11 is offset from the axis of the crushing cone 6. The bottom of the feeding disc 11 is in contact with the top of the crushing cone. When the rotating sleeve 9 rotates on the main shaft 8, the feeding disc 11 also moves on the crushing cone 6. This allows the feeding disc 11 to more effectively push the raw materials of the lees on the crushing cone 6 into the gap between the collecting hopper 4 and the crushing cone 6 when it rotates.

[0040] like Figure 5 and Figure 6 As shown, multiple circumferentially evenly distributed material-pushing blades 25 are also fixed on the conical surface 19 of the crushing cone 6. The material-pushing blades 25 have a spiral structure; when the crushing cone 6 rotates, the material-pushing blades 25 push the lees in the gap between the collecting hopper 4 and the crushing cone 6 downwards. This helps the lees to better contact the crushing cone 6 during the crushing process, further improving the crushing effect and ensuring that the lees are fully crushed.

[0041] To allow the rotating sleeve 9 to rotate on the main shaft 8, the transmission assembly designed in this invention transmits power between the main shaft 8 and the rotating sleeve 9, creating a speed difference between them. The transmission assembly includes a transmission housing 12, a countershaft 13, a first gear 14, a second gear 15, a third gear 16, and a fourth gear 17. The transmission housing 12 is fixed inside the crushing chamber 1 above the crushing cone 6, and the motor 7 is fixed to the top of the transmission housing 12. The main shaft 8 passes through the transmission housing 12, and the countershaft 13 is rotatably mounted inside the transmission housing 12. Figure 3 As shown, a first gear 14 and a second gear 15 are fixed on the secondary shaft 13. The diameter of the first gear 14 is smaller than the diameter of the second gear 15. A third gear 16 is fixed on the portion of the main shaft 8 located inside the transmission box 12. A fourth gear 17 is fixed on the portion of the rotating sleeve 9 located inside the transmission box 12. The diameter of the fourth gear 17 is smaller than the diameter of the third gear 16.

[0042] Since the third gear 16 meshes with the first gear 14 and the second gear 15 meshes with the fourth gear 17, it can not only transmit the power of the main shaft 8 to the rotating sleeve 9 to ensure the stable operation of the feeding device, but also the rotating sleeve 9 will rotate at a higher speed than the main shaft 8, thereby ensuring the stability of the feeding and crushing process of the lees.

[0043] In use, the raw materials of distiller's grains enter the crushing chamber 1 through the feed inlet 2. Under the action of the motor 7, the main shaft 8 and the rotating sleeve 9 rotate. Under the push of the feeding device, the raw materials of distiller's grains continuously gather in the gap between the gathering hopper 4 and the crushing cone 6. After being squeezed and sheared by the crushing cone 6, they are crushed into smaller particles, and then fall below through the discharge hole 5, and finally discharged from the discharge outlet 3.

[0044] Example 2

[0045] Based on Embodiment 1, this utility model further optimizes the material feeding device. For example... Figure 3 and Figure 5 As shown, this utility model has two feeding discs 11, which are symmetrically rotated and mounted on the connecting frames 10 on both sides of the rotating sleeve 9. This allows the two feeding discs 11 to rotate around the main shaft 8 during the crushing process, pushing the lees raw material towards the crushing area, making the raw material distribution more uniform, avoiding the accumulation of raw material on one side, and improving the crushing efficiency and effect.

[0046] Meanwhile, the crushing chamber 1 above the gathering hopper 4 is equipped with a splash guard section 18, such as Figure 3 As shown, the inner diameter of the splash guard 18 is smaller at the top and larger at the bottom, with the top sloping inwards. Simultaneously, the side wall of the feeding disc 11 is also designed as a conical surface 19. The conical surface 19, in conjunction with the splash guard 18, pushes the lees into the gap between the collecting hopper 4 and the crushing cone 6. When the lees are subjected to compression and shearing forces during crushing, splashing may occur. This design of the splash guard 18 and the feeding disc 11 effectively prevents the lees from splashing out of the crushing chamber 1, reducing raw material waste, improving the working environment, and lowering cleaning difficulty.

[0047] Example 3:

[0048] Based on Embodiments 1 and 2, this embodiment further adds screening and unblocking functions. For example... Figure 3 As shown, a screen 20 is installed inside the crushing chamber 1 between the discharge hole 5 and the outlet 3, and a sliding sleeve 21 is fitted on the main shaft 8. The sliding sleeve 21 is keyed to the main shaft 8, allowing the main shaft 8 to rotate with the sliding sleeve 21, while the sliding sleeve 21 has the freedom to move along the axial direction of the main shaft 8. A cleaning brush 22 for clearing the screen 20 is fixed on the sliding sleeve 21. During the rotation of the main shaft 8, the sliding sleeve 21 and the cleaning brush 22 also rotate, cleaning the screen 20. When the crushed lees fall into the screen 20 through the discharge hole 5, the lees that meet the particle size requirements pass through the screen 20 and are discharged into the outlet 3, while the lees that do not meet the requirements remain on the screen 20. A chamber door 26 is provided on one side of the crushing chamber 1, which can be opened periodically to clean the large particles of lees trapped on the screen 20.

[0049] To achieve better brushing results, a limiting ring 23 is fixed on the main shaft 8 near the material discharge hole 5 of the sliding sleeve 21, and a spring 24 is sleeved on the main shaft 8 between the limiting ring 23 and the sliding sleeve 21. This causes the spring 24 to press the sliding sleeve 21 down towards the screen 20, increasing the brushing force of the cleaning brush 22. When the cleaning brush 22 encounters greater resistance, the spring 24 can act as a buffer, protecting the equipment from damage, and also allowing the cleaning brush 22 to better adapt to the working state of the screen 20, improving the unblocking effect.

[0050] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
