Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, and in particular relates to an aggregate crushing device. Background Technology

[0002] Bovine bones, the skeletons of the yellow cattle (Bos spp.) or the water buffalo (Bos spp.), are used in traditional Chinese medicine for their effects in relieving numbness, treating malaria, and promoting wound healing. They are commonly used for arthritis, diarrhea, malaria, and malnutrition sores. Bovine bones also have high nutritional value. They contain calcium phosphate and calcium carbonate, which can supplement calcium, as well as various amino acids needed by the human body. Furthermore, bovine bones are rich in collagen, which can make the skin more beautiful and elastic.

[0003] Currently, people often process cattle bones into bone meal to achieve repeated resource utilization. Therefore, in the process of bone meal processing, it is necessary to use a crusher to crush the bones and then sieve them to process the bone material into powder, which is convenient to use. Moreover, using mechanized production equipment can greatly improve the production efficiency of bone meal.

[0004] Existing aggregate crushers require large cattle bones to be processed before being fed into the crusher, making the process cumbersome. In addition, since most aggregates are columnar and have smooth surfaces, they tend to spin freely above the crushing rollers during the crushing process, which affects the crushing efficiency. Therefore, there is an urgent need to design an aggregate crushing device to solve the above problems. Utility Model Content

[0005] This invention provides a reasonably structured aggregate crushing device to solve the technical problems existing in the prior art. This invention can perform primary coarse crushing and secondary fine crushing of aggregates, and can apply downward pressure to the aggregates during the feeding process to prevent the aggregates from spinning idly above the crushing rollers.

[0021] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail:

[0022] Please see Figure 1 The aggregate crushing device of this utility model includes a mounting base, a crushing box structure mounted on the mounting base, a pressing component 12 mounted at the feed inlet of the crushing box structure, two crushing roller structures 11 and two feed guide plates 9 arranged below the pressing component 12; an inclined guide plate 7 is mounted below the two crushing roller structures 11, a fine crushing fixed blade 6 is detachably mounted at the lower end of the guide plate 7, a fine crushing component 5 that cooperates with the fine crushing fixed blade 6 is mounted on the crushing box structure, an arc-shaped screen plate 4 for screening materials is arranged below the fine crushing component 5, and a rotary drive component 1 for driving the two crushing roller structures 11 and the fine crushing component 5 to rotate.

[0023] like Figure 2As shown, the aforementioned pressing assembly 12 includes an inclined pressing guide rail 12-4 fixedly connected to the feed inlet of the crushing box structure. In this embodiment, two sets of pressing guide rails 12-4 are provided, and the two sets of pressing guide rails 12-4 are inclined, with the inclination direction gradually approaching the middle position of the two crushing roller structures 11 from top to bottom. A mounting plate base 12-2 is slidably connected to the pressing guide rail 12-4 via a slider. A bent part is installed at the lower end of the mounting plate base 12-2. The structure includes a pressing plate 12-1; it also includes a pressing cylinder 12-3 mounted on the crushing box structure for driving the mounting plate seat 12-2 to move along the pressing guide rail 12-4; a cylinder seat 12-5 is fixedly connected to the crushing box structure, the cylinder barrel of the pressing cylinder 12-3 is pivotally connected to the cylinder seat 12-5 through a pin, and the extended end of the pressing cylinder 12-3 is pivotally connected to the mounting plate seat 12-2 through a connector and a pin; and several reinforcing ribs are installed on the inner side of the mounting plate seat 12-2.

[0024] like Figure 3 As shown, the above-mentioned crushing roller structure 11 includes a roller shaft 11-3 that is rotatably connected to the crushing box structure and arranged laterally, and a plurality of spacer sleeves 11-1 and coarse crushing tooth sleeves 11-2 that are spaced apart are installed on the roller shaft 11-3.

[0025] See further Figure 1 and Figure 5 The crushing box structure has transversely extending strip-shaped holes on two opposite side walls. The two ends of the crushing roller structure 11, which is away from the fine crushing component 5, are slidably inserted into the two strip-shaped holes. Two guide members 13, which are fixedly connected to the side wall of the crushing box structure, are provided above and below one strip-shaped hole. A T-shaped slider bearing is slidably connected between the two guide members 13. Guide members 13 and 2, which are fixedly connected to the side wall of the crushing box structure, are provided above and below the other strip-shaped hole, respectively. A T-shaped slider bearing is slidably connected between the guide members 13 and 2, respectively. The two ends of the crushing roller structure 11, which is away from the fine crushing component 5, are rotatably connected to the two T-shaped slider bearings. An adjusting screw 15 is movably connected to the outer end of each T-shaped slider bearing. The crushing box structure also includes two screw seats 14 installed on the crushing box structure. The two screw seats 14 are screwed into the two adjusting screws 15, respectively.

[0026] In this embodiment, the inner end of the adjusting screw 15 passes through the through hole at the end of the corresponding T-shaped slider bearing and is movably connected to the corresponding T-shaped slider bearing through a locking nut. With this configuration, the distance between the two crushing roller structures 11 can be adjusted according to actual conditions, thereby ensuring that the two crushing roller structures 11 can pre-crush aggregates of different sizes and ensuring smooth feeding operation.

[0027] like Figure 4As shown, the fine crushing component 5 includes a fine crushing shaft 5-4 rotatably connected to the crushing box structure and arranged laterally. A cross blade holder 5-3 is mounted on the fine crushing shaft 5-4. Multiple cutter seat plates 5-2 distributed circumferentially are fixed to the ends of the cross blade holder 5-3. Fine crushing cutters 5-1 are detachably connected to each cutter seat plate 5-2. In order to reduce the shearing resistance of the fine crushing cutters 5-1, improve the crushing effect of the material, and increase the efficiency of the crushing device, in this embodiment, each of the fine crushing cutters 5-1 is inclined, so that the contact between the material and the fine crushing cutter 5-1 is not completed in one go, but is gradually cut in. In addition, the inclined fine crushing cutter 5-1 forms a dynamic shearing angle during rotation, and the material is subjected to the superposition of tearing, squeezing and shearing, resulting in more uniform crushing.

[0028] See further Figure 5 and Figure 6 The aforementioned rotary drive assembly 1 includes a crushing motor 1-1 mounted on a mounting base, a pulley drive pair 1-2 installed between the output shaft of the crushing motor 1-1 and the end of the fine crushing assembly 5; a transmission gear set one is installed between the other end of the fine crushing assembly 5 and the adjacent crushing roller structure 11, for driving the fine crushing assembly 5 and the adjacent crushing roller structure 11 to rotate synchronously; a transmission gear set two is installed between the other ends of the two crushing roller structures 11, so that the two crushing roller structures 11 rotate synchronously towards each other.

[0029] The transmission gear set includes a shaft gear 1-6 keyed to the end of the fine grinding component 5, and a drive gear 1-5 keyed to the end of the grinding roller structure 11 adjacent to the fine grinding component 5. A plurality of intermediate transmission gears 1-7 are arranged between the shaft gear 1-6 and the drive gear 1-5, meshing with both. The shaft gear 1-6 is a small gear, the drive gear 1-5 is a large gear, and the number of intermediate transmission gears 1-7 is odd. This arrangement ensures that both the fine grinding component 5 and the adjacent grinding roller structure 11 rotate clockwise, and that the rotational speed of the fine grinding component 5 is greater than the rotational speed of the grinding roller structure 11.

[0030] The transmission gear set two includes roller gear 1-3 keyed to the ends of each crushing roller structure 11, and two roller gear 1-4 rotatably connected to the guide member 16 and whose positions are adjustable. The two roller gear 1-4 mesh with each other and are respectively meshed with the two roller gears 1-3. The roller gear 1-4 includes a shaft mounted on the guide member 16, and a gear is rotatably connected to the shaft via a rolling bearing. In addition, the position of the shaft in the two roller gears 1-4 on the guide member 16 is adjustable, thereby ensuring that when the lateral position of the crushing roller structure 11 away from the fine crushing component 5 changes, the corresponding roller gear 1-4 is always meshed with the roller gear 1-3 mounted at its end. Specifically, a strip hole is provided on the guide member 16, and the shaft is locked to the guide member 16 by bolts and lock nuts passing through the strip hole.

[0031] In addition, such as Figure 1 As shown, the above-mentioned crushing box structure includes a fine crushing box 3 mounted on a mounting base. A feed inlet is provided on the side of the fine crushing box 3, and a coarse crushing box 8 is installed at the feed inlet. A feed hopper 10 is fixedly connected to the top opening of the coarse crushing box 8. A pressing assembly 12 is installed on the side wall of the feed hopper 10. A window is provided at the lower part of the side wall of the fine crushing box 3, and a receiving box 2 is inserted into the window for receiving the crushed material. Further, the fine crushing box 3 includes a lower box body fixedly mounted on a mounting base 13. An upper box body is detachably connected to the lower box body by bolts and locking nuts. The upper box body is fixedly connected to the coarse crushing box 8, and the coarse crushing box 8 is connected to the fine crushing box 3 by bolts and locking nuts.

[0032] Working principle:

[0033] In actual operation, the aggregate to be crushed is fed into the feed hopper 10. Then, the pressing cylinder 12-3 in the pressing assembly 12 is activated, pushing the mounting plate 12-2 and the pressing plate 12-1 mounted on it to move downward, thereby applying downward pressure to the aggregate. This allows the aggregate to fully contact the two opposing rotating crushing roller structures 11, ensuring that the two opposing rotating crushing roller structures 11 can perform pre-crushing operations on the aggregate and achieve smooth downward feeding, preventing the aggregate from spinning idly above the crushing roller structures 11. The aggregate that has completed the above pre-crushing operation falls onto the guide plate 7 and moves downward along the guide plate 7. During this process, the fine crushing fixed blade 6, in conjunction with the rotating fine crushing assembly 5, can further crush the aggregate sliding down the guide plate 7. The material that has undergone secondary crushing falls into the receiving box 2 after being screened by the arc screen plate 4, thereby achieving material collection and finally realizing the crushing operation of the aggregate.
