Description

Technical Field

[0001] The present invention relates to the technical field of mushroom processing, in particular to a mushroom polysaccharide extraction device. Background Art

[0002] During the mushroom polysaccharide extraction process, raw material grinding directly impacts extraction efficiency and costs. Common grinding equipment utilizes a single or double roller structure, resulting in uneven grinding and uneven particle size, leading to poor extraction results. Fixed filters are prone to clogging after prolonged use, requiring equipment shutdown for cleaning, disrupting production continuity. The equipment's complex internal structure makes assembly and disassembly of the filter and grinding components difficult, making cleaning and maintenance time-consuming. Repeated feeding of unground material increases energy consumption and labor. These factors reduce production efficiency and increase overall costs.

[0003] To solve the above problems, this application proposes a mushroom polysaccharide extraction device that integrates efficient crushing, intelligent filter switching and rapid maintenance functions, which improves the degree of automation and production efficiency of the pretreatment link. Summary of the Invention

[0009] The bottom of the protection box is provided with a limiting annular groove, an external ring is rotatably connected to the inside of the limiting annular groove, a plurality of through holes are formed in the inside of the external ring, a plug-in hole is formed in the bottom of the external ring and is in communication with the through holes, the same filter plate is plugged into the inside of the limiting annular groove and the through holes, a plurality of fixed arc-shaped strips are fixedly sleeved on the outer wall of the crushing disc, and one end of the fixed arc-shaped strips is provided with a limiting assembly for limiting the filter plate.

[0010] Wherein, the material enters the crushing cavity through the inner cylinder, the driving assembly drives the crushing assembly to rotate to crush the material, the crushed material falls into the conical groove after being screened by the filter plate, and the external ring can be rotated to switch the position of the through hole, so that the filter plate is replaced to maintain continuous production.

[0011] In a possible design, the crushing assembly includes a plurality of driving shafts, the outer wall of the driving shaft is fixedly sleeved with a crushing roller, the outer wall of the crushing roller is fixedly connected with a plurality of crushing protrusions, the bottom of the protection box is provided with a plurality of second accommodating holes, the inside of the protection box is provided with an annular cavity, the annular cavity is in communication with the second accommodating holes, and the top of the driving shaft penetrates through the second accommodating hole and is rotatably connected to the top inner wall of the annular cavity.

[0012] In a possible design, the driving assembly includes a plurality of connecting gears, the inside of each of the connecting gears is provided with a first accommodating hole, the driving shaft fixedly penetrates through the first accommodating hole, the connecting gears are meshed with each other, the top of the protection box is fixedly connected with a servo motor, the output shaft of the servo motor penetrates through the protection box and is fixedly connected with the top of one of the driving shafts.

[0013] In a possible design, the limiting assembly includes an arc-shaped groove formed on one side of the top of the fixed arc-shaped strip, a sliding arc-shaped block is slidably penetrated into the inside of the arc-shaped groove, one end of the sliding arc-shaped block and the inner wall of one side of the arc-shaped groove are provided with the same compression spring, the two ends of the compression spring are fixed to one end of the sliding arc-shaped block and the inner wall of one side of the arc-shaped groove through spring seats, and the sliding arc-shaped block and the fixed arc-shaped strip are located below the filter plate.

[0014] In a possible design, a circular hole is formed in the middle of the bottom of the support plate, a discharge pipe is fixedly connected to the middle of the bottom of the support plate, and supporting legs are fixedly connected to the four corners of the bottom of the support plate.

[0015] In a possible design, the two sides of the protection box are fixedly connected with fixed rods, the top of the support plate is provided with a sliding outer frame, two symmetrical sliding grooves are formed in the inner wall of the sliding outer frame, and the fixed rods are slidably connected in the inside of the sliding grooves.

[0016] In a possible design, when the filter plate is blocked, press the sliding arc-shaped block to compress the compression spring and shrink into the arc-shaped slot to expose the plug-in hole, and rotate the external ring to align another through hole with the notch of the crushing cavity to switch the filter plate.

[0017] In a possible design, after disassembling the screws between the protective box and the crushing disc, pull up the fixed rod to make the protective box and the sliding outer frame as a whole separate from the support plate, and take out the external ring from above to expose the crushing cavity for cleaning.

[0018] In a possible design, the crushing protrusions are semispherical, and the plurality of crushing rollers are synchronously rotated through the meshing of the connecting gears to improve the crushing efficiency and particle size uniformity.

[0019] In this application, when in use, the frozen mushrooms are cut into pieces, which are then put into the device through the feed hopper. After being put in, the mushrooms enter the inside of the crushing disc through the inner cylinder in the center of the protective box and are between the four crushing rollers, preparing for the subsequent crushing process.

[0020] Start the servo motor, and the output shaft of the servo motor drives the driving shaft to rotate, and the driving shaft drives the connecting gears on the outer wall to rotate. The plurality of connecting gears mesh with each other and can drive the plurality of crushing rollers to rotate. The crushing rollers drive the external crushing protrusions to rotate, and the crushing protrusions continuously crush the materials in the inside. The crushed materials are discharged through the notches around the crushing cavity.

[0021] The notches correspond to the filter plate, so that the mushrooms of the specified size can be discharged through the filter plate. Mushrooms that cannot be discharged are crushed multiple times and then discharged. At this time, the discharged materials can be blocked by the sliding outer frame and slide out along the inclined surface of the conical groove, and finally be sent into the inside of the collection box through the discharge pipe to complete the collection process.

[0022] When the filter plate is blocked, the sliding outer frame can be slid upward along the fixed rod, and another through hole can be adjusted to the notch by rotating the external ring, so that the mushrooms can be screened by another filter plate. When it is necessary to insert and take out the filter plate, the sliding arc-shaped block can be pressed, and the sliding arc-shaped block extrudes the compression spring at this time. The sliding arc-shaped block enters the inside of the arc-shaped slot, and the plug-in hole is exposed. After the filter plate is inserted, the sliding arc-shaped block seals the filter plate. Another filter plate is always on the top of the fixed arc-shaped strip and cannot be separated. When the external ring is rotated, the blocked filter plate is removed from the top of the fixed arc-shaped strip, and then it can be directly taken out for cleaning.

[0023] After use, the screws connecting the protective box and the crushing disc can be disassembled, and then the protective box and the sliding outer frame can be taken out as a whole. The external ring can also be directly taken out from above, and then the space on the top of the crushing disc can be exposed for cleaning the inside for the next use.

[0024] Advantages:

[0025] Through the linkage design of four rolling rollers and external rolling protrusions, combined with the gear transmission system driven by the servo motor, the multi-directional synchronous crushing of the material is realized, the single processing time is significantly shortened, and the particle size uniformity is improved.

[0026] The external ring cooperates with the multi-hole structure to quickly switch the standby filter screen when the filter plate is blocked, so that continuous production can be maintained without stopping, and the utilization rate of the equipment is improved.

[0027] The protection box and the crushing disc are detachably connected through screws, combined with the quick lifting structure of the sliding outer frame, the internal cleaning time of the equipment is shortened; the filter plate is installed in a plug-in manner, combined with the elastic limiting mechanism of the sliding arc block, the filter screen replacement is quickly completed.

[0028] The slope design of the conical groove and the discharge pipe makes the crushed material automatically gather to the collection point, the residual rate is low, and the sliding outer frame barrier function effectively prevents material splashing pollution.

[0029] The servo motor drives the synchronous operation of the multiple rollers through gear engagement, which can reduce energy consumption compared with the traditional multiple motor drive scheme, and reduce mechanical failure points, so that the stability of the equipment is significantly improved.
