[0022] 2. In the present invention, by providing a cleaning mechanism, the bristles on the cleaning roller can clean the pulp adhered to the crushing roller, and under the action of the scraper, self-cleaning of the cleaning roller can be achieved, which helps to improve the maximum utilization of resources and the efficiency of brass extraction. Through effective crushing operations, it can ensure that the hawthorn fruit fully releases the pulp, avoiding waste, and the cooperation of the cleaning mechanism ensures the clean separation of the pulp during the crushing process, reducing residues and improving the purity of subsequent extraction.

[0036] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0037] Example 1, as shown in Figure 1 and Figure 2 shown, a crushing device for extracting hawthorn flavonoids includes an outer shell 1, a control box 2 is fixedly installed at the front end of the outer shell 1, support plates 3 are symmetrically and fixedly connected to the front and rear of the lower end of the outer shell 1, a pit-removing assembly 4 is arranged on the inner surface of the outer shell 1, and a crushing assembly 5 is arranged below the pit-removing assembly 4 on the inner surface of the outer shell 1.

[0038] In the process of implementation of this embodiment, the head and tail of the hawthorn fruit are horizontally placed inside the pit-removing component 4, and then the control box 2 is operated, so that the head and tail of the hawthorn fruit are automatically fixed during the conveying process. When the hawthorn fruit moves to the set position, the pit-removing component 4 separates the fruit stones at this time, and removes multiple fruit stones inside. The pitted hawthorn is crushed by the crushing component 5.

[0039] The above-mentioned control box 2 is a mature control technology means and equipment in the prior art. In this solution, the functions that can be controlled are utilized, and its internal structure, principle and connection method will not be elaborated.

[0040] Specifically, in order to remove the pits of the hawthorn fruit, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , in this embodiment, the pit-removing component 4 includes a partition 41 fixedly connected to the inner surface of the outer shell 1. Below the partition 41 on the inner surface of the outer shell 1, a conveying mechanism 42 is provided. An extrusion mechanism 43 is provided on the inner surface of the conveying mechanism 42. At the lower end of the partition 41, an opening and closing mechanism 44 and a pit-removing mechanism 45 are provided.

[0041] Furthermore, refer to Figure 3 and Figure 4 , in this embodiment, the conveying mechanism 42 includes two fixing plates 421 fixedly connected to the front and back of the left end of the outer shell 1 symmetrically. A rotating rod 422 is rotatably connected to the inner surfaces of the two fixing plates 421 and the inner surface of the outer shell 1. Hardened conveyor belts 425 are wound around the outer surfaces of the two rotating rods 422 symmetrically in the front and back. A servo motor 423 fixedly connected to the front end of the outer shell 1 is fixedly connected to the front end of the rotating rod 422. A number of grooves 424 are annularly and equidistantly formed on the outer surfaces of the two hardened conveyor belts 425.

[0042] Furthermore, refer to Figure 3 、 Figure 5 and Figure 6 , in this embodiment, the extrusion mechanism 43 includes extrusion rods 431 slidably connected to the inner surfaces of a number of grooves 424 symmetrically in the front and back. Return springs 432 are sleeved on the outer surfaces of the extrusion rods 431. The mutually approaching ends of the two extrusion rods 431 on the same side are fixedly connected with spring telescopic rods 433. The mutually approaching ends of the two spring telescopic rods 433 on the same side are fixedly connected with fixing rings 434. The two ends of a number of return springs 432 are respectively fixedly connected to one end of the hardened conveyor belt 425 and the hemispherical blocks on the extrusion rods 431. An extrusion ring 435 is fixedly connected to the inner surface of the outer shell 1, and the four extrusion rings 435 are symmetrically distributed in pairs.

[0043] During the implementation process, the head and tail of the hawthorn fruit are placed horizontally in the groove 424. Subsequently, the output end of the servo motor 1 423 drives the rotating rod 422 located on the right to rotate through a coupling. Under the action of the winding connection, the rigid conveyor belt 425 is driven to move to the right. At this time, the extrusion rod 431 can move with the rigid conveyor belt 425. When the extrusion rod 431 moves to the convex part of the extrusion ring 435, the two extrusion rods 431 inside the groove 424 will move closer to each other, causing the return spring 432 to be in a compressed state. The two fixed rings 434 can move closer to each other to fix the head and tail of the hawthorn fruit, and at the same time, under the action of the spring telescopic rod 433, hawthorn fruits of different sizes can be clamped, always keeping the hawthorn fruit in the middle position of the groove 424.

[0044] Secondly, when the two extrusion rods 431 move away from the convex part of the extrusion ring 435, at this time, under the action of the return spring 432, the two fixed rings 434 can move away from each other, and the hawthorn fruit is no longer clamped and fixed, providing an accurate position for subsequent pit removal.

[0045] Further, refer to Figure 3 and Figure 8 In this embodiment, the pit removal mechanism 45 includes an oil tank 451 fixedly connected to the upper end of the partition plate 41. A servo motor 2 452 is fixedly connected to the upper end of the partition plate 41. The left output end of the servo motor 2 452 is fixedly connected to a threaded rod 453 through a coupling. A push plate 454 that is threadedly connected to the outer surface of the threaded rod 453 and slidably connected to the inner surface of the oil tank 451. The front and rear ends of the lower end of the partition plate 41 are symmetrically and fixedly connected with cylinders 455. The lower ends of the two cylinders 455 are jointly fixedly connected with a rectangular block 456. The front part of the lower end of the rectangular block 456 is fixedly connected with an inclined panel 457. The lower end of the rectangular block 456 is fixedly connected with cylinders 458 in a rectangular symmetry. The inner surfaces of the same-side cylinders 458 are all slidably connected with piston rods 459. The mutually approaching ends of the same-side piston rods 459 are jointly rotatably connected with a pit removal clamp 4510. The inner surfaces of the same-side two cylinders 458 and the inner surface of the oil tank 451 are connected through a pipeline.

[0046] During the implementation process, when the hawthorn fruits on the rigid conveyor belt 425 move to the set position, the air cylinder 455 is activated to push the rectangular block 456 downward, and during the movement, the stone-removing clamp 4510 is driven downward. When it moves to the set height, the output end of the servo motor two 452 drives the threaded rod 453 to rotate through the coupling. Since the threaded rod 453 is threadedly connected to the push plate 454, the push plate 454 slides on the inner surface of the fuel tank 451, and the hydraulic oil in the fuel tank 451 enters the inner cavity of the cylinder 458 through the pipeline. The two piston rods 459 on the same side move closer to each other towards the middle, and then the stone-removing clamps 4510 can be pushed to move towards the middle. The stone-removing clamps 4510 break open most of the fruits, and under the action of the stone-removing clamps 4510, the fruit stones in the hawthorn are clamped. Subsequently, through the above reverse operation, the fruit stones can be picked up and released. By breaking open the hawthorn fruits with the stone-removing clamps 4510, the interference of the fruit stones on the subsequent processing process can be reduced, thereby improving the extraction efficiency of hawthorn pulp and the recovery rate of brass, enabling the fruit stones to be efficiently clamped, which helps to improve the purity of the material during the brass extraction process, reduce the mixing of impurities, improve the extraction effect and efficiency, can provide a more stable and accurate clamping force, effectively reduce the residue and loss of the fruits on the fruit stones, make full use of the pulp, and ensure the integrity of the fruits.

[0047] The above-mentioned stone-removing clamp 4510 is a mature stone-removing technical means and equipment in the prior art. In this solution, its function of removing the stones from hawthorn is utilized, and its internal structure and principle will not be elaborated further.

[0048] The pipelines connecting the two cylinders 458 on the same side to the fuel tank 451 mentioned above are flexible pipelines.

[0049] Further, referring to Figure 3 and Figure 7 In this embodiment, the opening and closing mechanism 44 includes two connecting plates 441 fixedly connected to the lower end of the partition plate 41 symmetrically left and right. The inner surfaces of the two connecting plates 441 are rotatably connected with inclined plates 442, and a number of spring pieces 443 are fixedly connected to the same side of the connecting plate 441 and the inclined plate 442.

[0050] During the implementation process, when the rectangular block 456 moves downward, the inclined panel 457 at the front part of the lower end of the rectangular block 456 will gradually come into contact with the inclined plate 442, causing the two inclined plates 442 to rotate on the inner surface of the connecting plate 441. Under the squeezing action, the lower openings of the inclined plates 442 will gradually move away from each other, causing the inclined plates 442 to open. And during this process, the spring piece 443 is in a deformed state. After the fruit core is clamped and taken, when the inclined panel 457 moves upward, the two inclined panels 457 will reset under the action of the deformation force of the spring piece 443 and move closer to each other to form a conical inclined channel. The clamped fruit core can fall backward through the inclined plate 442, excluding the inner cavity of the outer shell 1, realizing the separation of the fruit core from the pulp and avoiding the fruit core from affecting the subsequent crushing operation of the pulp.

[0051] The spring piece 443 mentioned above is a mature technical means and conventional design in the prior art, and the internal structure and materials thereof will not be elaborated in this solution.

[0052] Embodiment 2: On the basis of Embodiment 1, this embodiment adds a crushing assembly 5 for crushing the pitted hawthorn to achieve the purpose of crushing the pitted hawthorn.

[0053] Specifically, in order to crush the pitted hawthorn, referring to Figure 3 、 Figure 9 、 Figure 10 and Figure 11 , in this embodiment, the crushing assembly 5 includes a collection box 51 movably installed on the lower part of the inner surface of the outer shell 1, a feeding plate 55 fixedly connected to the right part of the inner surface of the outer shell 1, a blocking plate 56 fixedly connected to the front and rear parts of the inner surface of the outer shell 1 together, a crushing mechanism 52 arranged below the feeding plate 55 and the blocking plate 56 on the inner surface of the outer shell 1, a cleaning mechanism 53 arranged on the inner surface of the outer shell 1, and a cooling mechanism 54 arranged on the lower left side of the inner surface of the outer shell 1.

[0054] Furthermore, referring to Figure 3 and Figure 10 , in this embodiment, the crushing mechanism 52 includes two crushing rollers 521 rotatably connected to the inner surface of the outer shell 1. A servo motor three 522 is fixedly connected to the rear end of the outer shell 1. A gear one 523 is fixedly connected to the outer surface of the transmission rod connected to the output end of the servo motor three 522 through a coupling. Two gears two 524 are fixedly connected to the rear parts of the outer surfaces of the two crushing rollers 521 and mesh with each other. The gear two 524 located on the right is meshed and connected with the gear one 523.

[0055] Furthermore, referring to Figure 3 and Figure 10, in this embodiment, the cleaning mechanism 53 includes two cleaning rollers 531 rotatably connected symmetrically left and right to the inner surface of the housing 1. Pulley sets 533 are fixedly connected to the front parts of the outer surfaces of the two cleaning rollers 531 and the front parts of the outer surfaces of the two crushing rollers 521. Scrapers 532 are fixedly connected symmetrically left and right to the inner surface of the housing 1.

[0056] During the implementation process, the hard conveyor belt 425 continues to move to the right. After the pits are removed, the hawthorn fruits will fall on the blanking plate 55 under the action of gravity. Since the blanking plate 55 is inclined and cooperates with the blocking plate 56, the hawthorn fruits can smoothly fall between the two crushing rollers 521. At this time, the output end of the servo motor three 522 drives the gear one 523 on the transmission rod to rotate through a coupling. Under the meshing connection, the two gears two 524 rotate towards the middle of each other, driving the two crushing rollers 521 to perform crushing operations on the hawthorn fruits. At the same time, under the transmission of the pulley set 533, the two cleaning rollers 531 can rotate in the same direction as the crushing rollers 521, so that the bristles on the cleaning rollers 531 can clean the pulp adhered to the crushing rollers 521, and self-cleaning of the cleaning rollers 531 is achieved under the action of the scrapers 532, which helps to improve the maximum utilization of resources and the efficiency of brass extraction. Through effective crushing operations, it can ensure that the hawthorn fruits fully release the pulp, avoiding waste, and the cooperation of the cleaning mechanism ensures the clean separation of the pulp during the crushing process, reducing residues and improving the purity of subsequent extraction. The self-cleaning function not only improves the working efficiency of the equipment but also avoids the accumulation of pulp, ensuring the continuous and stable operation.

[0057] The above-mentioned pulley set 533 is composed of two pulleys and a belt in the prior art.

[0058] The above-mentioned servo motor one 423, servo motor two 452, and servo motor three 522 are all mature driving technical means and equipment in the prior art. In this solution, the output end is used to drive the coupling to rotate forward and backward, and can be locked in time after rotating a set number of turns. The internal structure, principle, and connection method will not be elaborated further.

[0059] Further, referring to Figure 3 and Figure 11 , in this embodiment, the cooling mechanism 54 includes a water tank 541 fixedly connected to the lower part of the inner surface of the housing 1. Spiral rings 542 are fixedly connected to the inner surfaces of the two crushing rollers 521. A connecting pipe one 543 rotatably connected to the crushing roller 521 is fixedly connected to the upper part of the inner surface of the water tank 541. A water pump 544 is fixedly connected to the lower end of the connecting pipe one 543. A connecting pipe two 545 rotatably connected to the crushing roller 521 is fixedly connected to the upper part of the inner surface of the water tank 541. A plurality of heat dissipation fins 546 are fixedly connected to the left end of the water tank 541.

[0060] During the implementation process, when the crushing roller 521 crushes hawthorn fruits, the water pump 544 is started at this time to pump the water in the water tank 541 through the first connecting pipe 543 into the inner cavities of the two crushing rollers 521. Under the action of the spiral ring 542, the water can evenly absorb the heat generated by the crushing rollers 521. At the same time, the water after absorbing the heat returns to the water tank 541 through the second connecting pipe 545 and conducts heat dissipation operation through the heat dissipation fins 546, effectively controlling the heat generated during the crushing process, ensuring the stable temperature of the crushing rollers 521, thus avoiding the influence of excessive temperature on hawthorn fruits, keeping the temperature within the ideal range, which helps to ensure the uniform crushing of hawthorn fruits, release the pulp to the greatest extent, improve the crushing efficiency, contribute to improving the efficiency and purity of brass extraction, reduce material losses caused by overheating, and ultimately achieve the maximization of resource utilization and the high-efficiency and stability of the production process.

[0061] The above heat dissipation fins 546 are mature heat dissipation technical means and conventional technical designs in the prior art, and the materials and principles thereof will not be elaborated in this solution.

[0062] Example 3, the present invention also provides a method for using the crushing device for extracting hawthorn flavonoids, and the method includes:

[0063] S1. Conveying stage: Place the head and tail of the hawthorn fruit horizontally in the groove 424, and then start the output end of the first servo motor 423 to drive the rotating rod 422 located on the right to rotate through the coupling. Under the action of the winding connection, drive the rigid conveyor belt 425 to move to the right. At this time, the extrusion rod 431 can move along with the rigid conveyor belt 425. When the extrusion rod 431 moves to the convex part of the extrusion ring 435, the two extrusion rods 431 inside the groove 424 will approach each other towards the middle, making the return spring 432 in a compressed state, and the two fixing rings 434 can approach each other to realize the fixing operation of the head and tail of the hawthorn fruit.
