Description

Technical Field

[0001] This application relates to the field of kudzu root powder production technology, and specifically discloses a crushing device for kudzu root powder production equipment. Background Technology

[0002] Kudzu root powder is starch extracted from the tuberous roots of the kudzu plant (Pueraria lobata). Crushing is an essential step in its production. Crushing breaks down the cell walls and fibrous tissue of the kudzu root, releasing starch granules and creating favorable conditions for subsequent starch extraction, thus increasing the extraction rate. The crushed kudzu root powder, in the form of uniform small pieces or a paste, is more effective in removing impurities and further purifying the starch during subsequent processes such as pulp-residue separation, sand removal, and protein separation. Furthermore, during drying, the crushed kudzu root powder is heated more evenly, shortening the drying time and improving the overall production efficiency. The crushing process also ensures more uniform processing of the kudzu root powder, avoiding uneven processing caused by variations in the size and shape of the raw materials.

[0003] Current crushing devices for kudzu root powder mostly adopt a structure of crushing first and then screening. This not only increases the cost of transporting kudzu root powder back and forth, but also makes it impossible to screen out kudzu root powder with unqualified particle size in a timely manner and return it to the crushing device for secondary crushing, resulting in low efficiency. Therefore, in view of this, this utility model provides a crushing device for kudzu root powder production equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional crushing devices cannot screen kudzu root powder with unqualified particle size in a timely manner, which leads to a prolonged production process and reduced production efficiency.

[0005] To achieve the above objectives, the basic solution of this utility model provides a crushing device for kudzu root powder production equipment, including: a frame;

[0006] The crushing assembly includes a crushing bin mounted on a frame, crushing rollers symmetrically rotatably connected within the crushing bin, and a drive mechanism for driving the crushing rollers to rotate relative to each other. The top and bottom of the crushing bin are respectively provided with a feed inlet and a discharge outlet.

[0007] The screening assembly includes a sliding frame slidably connected to the frame and located below the discharge port, a screen disposed within the sliding frame, and a sliding mechanism for driving the sliding frame to slide along the frame. The frame is provided with a guide trough located below the sliding path of the sliding frame and a collection hopper communicating with the bottom of the guide trough.

[0008] The principle and effect of this basic scheme are as follows:

[0009] Compared with the prior art, this utility model sets up a screening component below the discharge port and uses a sliding mechanism to drive the sliding frame to move. The screen inside the sliding frame moves back and forth under the action of the sliding frame, so that the kudzu root powder enters the sliding frame after crushing and is subjected to reciprocating vibration screening. The qualified material enters the collection hopper through the guide chute for centralized collection, while the unqualified material stays in the sliding frame. This helps the workers to promptly send the unqualified material back into the crushing chamber for secondary crushing, thereby improving the crushing efficiency and production efficiency of kudzu root powder. This solves the problem that traditional crushing devices cannot screen kudzu root powder with unqualified particle size in time, resulting in a prolonged kudzu root powder production process and reduced production efficiency.

[0010] Furthermore, the drive mechanism includes a motor and a gear pair rotatably connected to the crushing chamber and meshing with the crushing rollers, and driven by the output shaft of the motor. The motor drives the gear pair to rotate, which in turn drives the two crushing rollers to rotate in opposite directions.

[0011] Furthermore, the sliding mechanism includes a rotating wheel that is driven and rotatably connected to the output shaft of the motor, a rocker arm hinged to the rotating wheel, a connecting rod hinged to the free end of the rocker arm, and a slider hinged to the free end of the connecting rod and slidably connected to the frame. The sliding frame is slidably connected to the slider. The motor drives the rotating wheel to rotate, which in turn drives one end of the rocker arm to rotate, causing the connected end to swing, thereby driving the slider and the sliding frame to slide.

[0012] Furthermore, the output shaft of the motor is coaxially connected to a drive pulley, the drive gear in the gear pair is coaxially connected to a driven pulley, and the rotating wheel is coaxially connected to a tension pulley. A belt is tensioned between the drive pulley, the driven pulley, and the tension pulley. This tensioning mechanism not only tensions the belt but also drives the rotating wheel to rotate via the tension pulley, causing the sliding frame to reciprocate.

[0013] Furthermore, the frame is equipped with a limiting frame, and the side wall of the limiting frame has a sliding groove, in which the slider is slidably connected. The sliding groove can limit and guide the sliding of the slider and the sliding frame.

[0014] Furthermore, it also includes several scrapers disposed within the limiting frame and located below the sliding frame, with the top of the scrapers abutting against the bottom of the screen. The scrapers and the screen work together to scrape out the material inside the screen in a timely manner, thus preventing the screen from becoming clogged.

[0015] Furthermore, several elastic telescopic components are provided between the scraper and the sliding frame, and several protrusions are provided at the bottom of the sliding frame to compress the scraper. This causes the scraper to vibrate the screen, further preventing the screen from clogging.

[0016] Furthermore, the elastic telescopic component includes a fixed shaft connected to the sliding frame, a sliding sleeve slidably connected to the fixed shaft and connected to the scraper, and a spring disposed within the sliding sleeve. This allows the sliding frame to bulge and compress the sliding sleeve during movement, thereby compressing the spring. The elastic potential energy of the spring causes the scraper to oscillate, thus producing an oscillating effect on the screen. Attached Figure Description

[0023] A crushing device for kudzu root powder production equipment, implementing, for example Figure 1 As shown: It includes a frame, a crushing component mounted on the frame for crushing kudzu root powder, and a screening component located at the bottom of the crushing component for screening the crushed material.

[0024] The crushing assembly includes a crushing chamber 2 mounted on a frame, a feed chamber 1 mounted on top of the crushing chamber 2, a discharge chamber 3 mounted on bottom of the crushing chamber 2, crushing rollers symmetrically rotatably connected within the crushing chamber 2, and a drive mechanism for driving the crushing rollers to rotate relative to each other. The top of the feed chamber 1 and the bottom of the discharge chamber 3 are respectively provided with a feed inlet and a discharge outlet.

[0025] The frame is equipped with a limiting frame 5. The screening component includes a sliding frame 4 that is slidably connected to the limiting frame 5 and located below the discharge port, a screen 13 located in the sliding frame 4, a number of scrapers 16 located in the limiting frame 5 and below the sliding frame 4, and a sliding mechanism that drives the sliding frame 4 to slide along the frame. The top of the scraper 16 and the bottom of the screen 13 are in contact with each other.

[0026] Correspondingly, the frame is provided with a guide trough located below the sliding path of the sliding frame 4 and a collection hopper 6 connected to the bottom of the guide trough.

[0027] The drive mechanism includes a motor 7 and a gear pair rotatably connected to the crushing chamber 2 and meshing with the crushing rollers. A gearbox 8 is provided on the side wall of the crushing chamber 2 to protect the gear pair. The sliding mechanism includes a rotating wheel 9 rotatably connected to the frame, a rocker arm 10 hinged to the rotating wheel 9, a connecting rod 11 hinged to the free end of the rocker arm 10, and a slider 12 hinged to the free end of the connecting rod 11 and slidably connected to the frame. Correspondingly, the side wall of the limiting frame 5 has a groove for the slider 12 to slide. The sliding frame 4 and the slider 12 are connected by multiple connecting posts 14. The output shaft of the motor 7 is coaxially connected to a drive pulley, the drive gear in the gear pair is coaxially connected to a driven pulley, and the rotating wheel 9 is coaxially connected to a tension pulley. A belt is tensioned between the drive pulley, the driven pulley, and the tension pulley.

[0028] like Figure 2 and Figure 3 As shown, a number of elastic telescopic components are provided between the scraper 16 and the sliding frame 4. The elastic telescopic components include a fixed shaft 18 connected to the sliding frame 4, a sliding sleeve 17 slidably connected to the fixed shaft 18 and connected to the scraper 16, and a spring provided in the sliding sleeve 17. A number of protrusions 15 for squeezing the scraper 16 are provided at the bottom of the sliding frame 4.

[0029] In this embodiment, kudzu root powder enters the crushing chamber 2 through the feed inlet at the top of the feeding hopper 1 for crushing. The motor 7 drives two crushing rollers to rotate in opposite directions via a belt and gear pair, thus crushing the kudzu root powder. After crushing, the powder enters the sliding frame 4. The motor 7 drives the sliding frame 4 and the screen 13 to move back and forth via a belt and sliding mechanism, causing the material in the sliding frame 4 to vibrate back and forth. Qualified material passes through the guide chute into the collection hopper 6 for centralized collection, while unqualified material remains in the sliding frame 4, helping workers to promptly remove unqualified material. The material is fed back into the crushing chamber 2 for secondary crushing, thereby improving the crushing efficiency and production efficiency of kudzu root powder. This solves the problem that traditional crushing devices cannot screen kudzu root powder with unqualified particle size in time, resulting in a prolonged production process and reduced production efficiency. In this process, as the sliding frame 4 moves, the scraper 16 can scrape the material in the screen 13 in time, and the protrusion 15 squeezes the sliding sleeve 17, thereby compressing the spring. The elastic potential energy of the spring makes the scraper 16 vibrate, which in turn produces a vibration effect on the screen 13, preventing the screen 13 from clogging.
