A circulating crushing and cleaning device for processing rhizoma polygonati tuberous roots

Abstract

This invention discloses a circulating crushing and washing device for processing Polygonatum sibiricum roots, specifically relating to the field of Polygonatum sibiricum root processing. It includes a crushing and washing box with a base frame fixedly installed at the bottom. Multiple winding crushing rollers are arranged inside the crushing and washing box. The invention works by using a push plate on a conveyor belt to push sliding rods on both sides, causing two limiting blocks to move inward synchronously. The limiting blocks on both sides simultaneously clamp and squeeze the pressure plate, causing rubber strips to clamp the roots on the Polygonatum sibiricum. The Polygonatum sibiricum with clamped roots is then synchronously carried to the bottom of the conveyor belt, separating the Polygonatum sibiricum with roots from those without. This facilitates the timely removal and removal of Polygonatum sibiricum with intact roots. Simultaneously, the Polygonatum sibiricum carried out by the conveyor belt is fed into a feeding trough via multiple lifting plates. The feeding trough then vibrates up and down repeatedly, facilitating continuous forward feeding. This allows the Polygonatum sibiricum with roots to be returned to the crushing and washing box for cyclic crushing and washing.

Description

Technical Field

[0001] This invention relates to the field of Polygonatum root processing technology, and more specifically, to a circulating crushing and cleaning device for processing Polygonatum roots. Background Technology

[0002] Polygonatum is a common medicinal plant. Cutting and breaking its roots is usually done to facilitate further processing, such as decoction, extraction of active ingredients, or use in traditional Chinese medicine. Here are the possible steps: Prepare tools: Choose sharp scissors or gardening tools, and a clean container or workbench. Cutting: First, dig out the root parts of the Polygonatum. If the rhizomes are long, cut them to appropriate lengths along the base for easier processing. Washing: Rinse the roots thoroughly with clean water to remove soil and impurities. Disinfection: If necessary, disinfect the roots with alcohol or boiling water to prevent bacterial contamination. Collection: Collect the broken Polygonatum roots together for later use.

[0003] However, traditional Polygonatum root processing equipment simply concentrates a large amount of Polygonatum for long-term crushing and washing. Because the existing technology lacks a structure to screen out Polygonatum roots that have not been broken during the crushing process, it is impossible to separate and remove some Polygonatum roots that have not been broken. As a result, it is impossible to process Polygonatum roots that have not been broken in time, and it can only be processed by traditional long-term and multiple crushing processes.

[0004] Meanwhile, the existing technology lacks a structure that can send the unbroken roots of Polygonatum back to the crushing and cleaning equipment for a second time. It cannot perform secondary crushing and cleaning of Polygonatum on its own, which means that traditional equipment can only achieve a single-time effect on the processing of Polygonatum, and cannot guarantee a thorough processing effect on the roots of Polygonatum.

[0005] To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0006] This invention provides a circulating crushing and cleaning device for processing Polygonatum sibiricum roots, to solve the technical problems mentioned in the background art, namely, the lack of a structure in the prior art to screen out Polygonatum sibiricum roots that are not broken during the crushing process, i.e., the inability to separately remove and carry away some Polygonatum sibiricum roots that are not broken, and the lack of a structure in the prior art to send Polygonatum sibiricum roots that are not broken back to the crushing and cleaning equipment, thus failing to perform secondary circulating crushing and cleaning of Polygonatum sibiricum on its own.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a circulating crushing and washing device for processing Polygonatum sibiricum roots, comprising a crushing and washing box, a base frame fixedly installed at the bottom of the crushing and washing box, multiple winding crushing rollers arranged inside the crushing and washing box, and a root-clamping separation mechanism and a circulating return mechanism arranged on one side of the crushing and washing box. The root-clamping separation mechanism can carry out the Polygonatum sibiricum that has been crushed and washed in the crushing and washing box, and clamp and carry out some of the Polygonatum sibiricum that still has roots attached, and then collect the Polygonatum sibiricum with roots attached and send it back to the crushing and washing box for secondary recycling processing through the circulating return mechanism.

[0008] In a preferred embodiment, the whisker separation mechanism includes a conveyor box fixedly installed on the inner wall of one side of the crushing and washing box. The conveyor box is inclined downward. A motor is fixedly installed on the outer wall of the conveyor box. A conveyor roller is fixedly installed at the output end of the motor. The conveyor roller is rotatably installed on the inner wall of the conveyor box. A conveyor belt is rotatably installed on the outer wall of the conveyor roller. The conveyor belt is inclined downward and located inside the crushing and washing box.

[0009] In a preferred embodiment, a plurality of baffle plates are fixedly installed on the outer wall of the conveyor belt. The plurality of baffle plates are arranged in a ring at equal intervals around the outer circumference of the conveyor belt. The plurality of baffle plates are arranged perpendicular to each other with respect to the conveyor belt. A discharge plate is provided on one side bottom of the conveyor belt. The discharge plate is fixedly installed on the inner wall of the crushing and washing box.

[0010] In a preferred embodiment, the outer wall of the conveyor belt has multiple slots, which are configured to cooperate with multiple baffles. Multiple sliding rods are slidably installed on the inner walls of both sides of the multiple slots. The sliding rods are arranged symmetrically in pairs. Two limiting blocks are fixedly installed on the opposite side of each pair of sliding rods. The two limiting blocks are arranged symmetrically in pairs. The outer walls of the two limiting blocks are sloped. Clamping plates are slidably installed on the outer walls of the two limiting blocks. The clamping plates and limiting blocks are staggered and symmetrically arranged. Rubber strips are fixedly installed on the outer walls of the two clamping plates.

[0011] In a preferred embodiment, the outer walls of the plurality of slide rods are respectively ball-jointed with balls, the balls being arranged symmetrically in pairs, the outer walls of the balls being provided with support springs, the support springs being fixedly installed on the outer wall of the conveyor belt, and one side of the outer wall of the balls being provided with a push plate, the push plate being fixedly installed on the conveyor box.

[0012] In a preferred embodiment, the circulating return mechanism includes a ramp trough located inside one side of the crushing and washing box, the ramp trough being at the bottom of the conveyor belt, a pulley fixedly mounted on one side of the outer wall of the conveyor roller, a synchronous belt rotatably mounted on the outer wall of the pulley, the synchronous belt being vertically arranged, a plurality of lifting plates fixedly mounted on the outer wall of the synchronous belt, the plurality of lifting plates being arranged in a ring at equal intervals, the plurality of lifting plates being staggered with the ramp trough, the plurality of lifting plates being inclined downwards, and a limiting box being provided on the top of the plurality of lifting plates, the limiting box being fixedly mounted on the top of the crushing and washing box.

[0013] In a preferred embodiment, a feeding trough is provided on one side of the limiting box. The feeding trough is rotatably mounted on the top of the crushing and washing box. The feeding trough is set in a horizontal state, and one end of the feeding trough is away from the conveyor belt.

[0014] In a preferred embodiment, a turntable is fixedly installed on the outer wall of the pulley, and a pusher plate is hinged to the outer wall of the turntable at its eccentric position. A horizontal pusher plate is hinged to one side of the pusher plate. The horizontal pusher plate is slidably installed on the top of the crushing and washing box. The horizontal pusher plate is horizontally positioned, and a locking block is fixedly installed at one end of the horizontal pusher plate. The top of one side of the locking block is sloped, and a support rod is provided on the top of the locking block. The outer wall of the support rod is in contact with the top of the locking block, and the support rod is fixedly installed on the outer wall of the feeding trough.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. This invention, by setting up a root separation mechanism, uses a rotating conveyor belt to drive multiple baffles to carry out the Polygonatum rhizome in batches from the crushing and washing box and send it out through the discharge plate. On the conveyor belt, the push plate pushes the sliding rods on both sides to move the two limiting blocks inward synchronously. The limiting blocks on both sides simultaneously clamp and squeeze the pressure plate. The pressure plate on both sides moves relative to each other due to the inclined surface and squeezing of the limiting blocks. That is, the pressure plate on both sides simultaneously drives the rubber strip to clamp the roots on the Polygonatum rhizome. The Polygonatum rhizome with the roots clamped is then synchronously carried to the bottom of the conveyor belt. At this time, the Polygonatum rhizome with roots and the Polygonatum rhizome without roots are separated, which makes it convenient to take out the Polygonatum rhizome with the roots that have not been broken in time.

[0017] 2. Simultaneously, a circulating feed mechanism is set up. The rooted Polygonatum sibiricum carried by the conveyor belt is concentrated at the position of the lifting plate through the inclined trough. Multiple lifting plates rotate to move the rooted Polygonatum sibiricum upward in sequence. The Polygonatum sibiricum carried by the multiple lifting plates enters the feeding trough. Then, the feeding trough shakes up and down to facilitate continuous forward feeding. The rooted Polygonatum sibiricum can be sent back to the crushing and washing box for cyclic crushing and washing through the feeding trough. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Existing technologies lack a structure capable of separating the remaining parts of the Polygonatum rhizome that are not completely severed during the crushing process. This means that it is impossible to separately process these remaining parts, leading to a delay in their individual processing and reliance on traditional, lengthy, and repeated crushing methods. To address this issue, the following technical solution is proposed:

[0029] Refer to the instruction manual appendix Figures 1-7 A circulating crushing and washing device for processing Polygonatum rootlets, such as Figure 1 and Figure 2 As shown, the device includes a crushing and washing box 1, with a base frame 2 fixedly installed at the bottom of the crushing and washing box 1. Multiple winding crushing rollers 3 are installed inside the crushing and washing box 1. A root separation mechanism 4 and a circulation return mechanism 5 are installed on one side of the crushing and washing box 1. The root separation mechanism 4 can carry out the Polygonatum rhizome that has been crushed and washed in the crushing and washing box 1. The root separation mechanism 4 can also clamp and carry out some of the Polygonatum rhizome that still has roots. Then, the circulation return mechanism 5 can collect the Polygonatum rhizome with roots and carry it out and send it back to the crushing and washing box 1 for secondary circulation processing.

[0030] like Figure 3 and Figure 4 As shown, the clamping and separating mechanism 4 includes a conveying box 41 fixedly installed on the inner wall of one side of the crushing and washing box 1. The conveying box 41 is inclined downward. A motor 42 is fixedly installed on the outer wall of the conveying box 41. A conveying roller 43 is fixedly installed at the output end of the motor 42. The conveying roller 43 is rotatably installed on the inner wall of the conveying box 41. A conveyor belt 44 is rotatably installed on the outer wall of the conveying roller 43. The conveyor belt 44 is inclined downward and located inside the crushing and washing box 1.

[0031] The start motor 42 drives the conveyor roller 43 to rotate, causing the conveyor belt 44 to rotate synchronously.

[0032] like Figure 3 and Figure 4 As shown, multiple baffle plates 45 are fixedly installed on the outer wall of the conveyor belt 44. The multiple baffle plates 45 are arranged in a ring at equal intervals around the outer circumference of the conveyor belt 44. The multiple baffle plates 45 are perpendicular to the conveyor belt 44. A discharge plate 46 is provided at the bottom of one side of the conveyor belt 44. The discharge plate 46 is fixedly installed on the inner wall of the crushing and washing box 1.

[0033] The rotating conveyor belt 44 drives multiple baffles 45 to carry out the Polygonatum rhizome in batches from the crushing and washing box 1 and send it out through the discharge plate 46.

[0034] like Figure 4 and Figure 5 As shown, the outer wall of the conveyor belt 44 has multiple slots, which are configured to cooperate with multiple baffle plates 45. Multiple sliding rods 47 are slidably installed on the inner walls of both sides of the multiple slots. The sliding rods 47 are arranged symmetrically in pairs. Two limiting blocks 48 are fixedly installed on the opposite side of the two sliding rods 47. The two limiting blocks 48 are arranged symmetrically in pairs. The outer walls of the two limiting blocks 48 are sloped. Clamping plates 49 are slidably installed on the outer walls of the two limiting blocks 48. The two clamping plates 49 and the limiting blocks 48 are arranged in an alternating manner. The two clamping plates 49 are arranged symmetrically in pairs. Rubber strips 410 are fixedly installed on the outer walls of the two clamping plates 49.

[0035] On the conveyor belt 44, the roots of some of the Polygonatum plants with roots on their outer surface extend into multiple slots. When the slide bars 47 on both sides are moved towards the center under force, the slide bars 47 on both sides drive the two limiting blocks 48 to move inward synchronously. The limiting blocks 48 on both sides clamp and squeeze the pressure plate 49 synchronously. Then, the pressure plate 49 on both sides moves relative to each other due to the inclined surface and squeezing of the limiting blocks 48. That is, the pressure plate 49 on both sides synchronously drives the rubber strip 410 to clamp the roots on the Polygonatum plants.

[0036] like Figure 4 and Figure 5 As shown, the outer walls of multiple sliding rods 47 are respectively ball-jointed with balls 411. The balls 411 are arranged symmetrically in pairs. The outer walls of the balls 411 are provided with support springs 412. The support springs 412 are fixedly installed on the outer walls of the conveyor belt 44. One side of the outer wall of the balls 411 is provided with a push plate 413. The push plate 413 is fixedly installed on the conveyor box 41.

[0037] When the slide bars 47 on both sides of the conveyor belt 44 slide to the position of the push plate 413, the width of the push plate 413 squeezes the ball bearings 411 and compresses the support spring 412, thereby causing the ball bearings 411 to move and squeeze the slide bars 47 to move inward. The length of the push plate 413 can squeeze the ball bearings 411 to move until the bottom of the conveyor belt 44. Then the Polygonatum odoratum with the roots is synchronously driven to the bottom of the conveyor belt 44 before the clamping plate 49 is released. At this time, the Polygonatum odoratum with roots and the Polygonatum odoratum without roots are separated.

[0038] In specific implementation, the starting motor 42 drives the conveyor roller 43 to rotate, so that the conveyor belt 44 rotates synchronously. The rotation of the conveyor belt 44 drives multiple baffle plates 45 to carry out the Polygonatum sibiricum in the crushing and washing box 1 in batches and send it out through the discharge plate 46. On the conveyor belt 44, the roots of some Polygonatum sibiricum with roots on the outer surface extend into multiple slots. When the slide rods 47 on both sides of the conveyor belt 44 slide to the position of the push plate 413, the width of the push plate 413 squeezes the ball 411 and compresses the support spring 412, so that the ball 411 moves and squeezes the slide rod 47 to move inward. When the slide rods 47 on both sides are forced to move towards the center, the slide rods 47 on both sides drive the two limit blocks 48 to move inward synchronously. The limit blocks 48 on both sides clamp and squeeze the pressure plate 49 synchronously. Then the pressure plates 49 on both sides move relative to each other due to the slope and compression of the limit blocks 48. That is, the pressure plates 49 on both sides drive the rubber strip 410 to clamp the roots on the Polygonatum sibiricum synchronously.

[0039] The length of the push plate 413 is sufficient to squeeze the ball bearing 411 to move until it reaches the bottom of the conveyor belt 44. The Solomon's seal with the root is then moved to the bottom of the conveyor belt 44 before the clamping plate 49 is released. At this point, the Solomon's seal with the root and the Solomon's seal without the root are separated, making it easier to remove the Solomon's seal with the root still intact in time.

[0040] Example 2

[0041] Existing technologies lack a structure capable of returning unbroken roots of Polygonatum sibiricum to the crushing and washing equipment for a secondary process. This prevents the equipment from performing a second cycle of crushing and washing, resulting in traditional equipment only achieving a single-pass processing effect and failing to guarantee thorough processing of the roots. To address this issue, the following technical solution is proposed:

[0042] like Figure 6 and Figure 7 As shown, the circulating return mechanism 5 includes a ramp trough opened inside one side of the crushing and washing box 1. The ramp trough is located at the bottom of the conveyor belt 44. A pulley 51 is fixedly installed on one side of the outer wall of the conveyor roller 43. A synchronous belt 52 is rotatably installed on the outer wall of the pulley 51. The synchronous belt 52 is set in a vertical state. Multiple lifting plates 53 are fixedly installed on the outer wall of the synchronous belt 52. The multiple lifting plates 53 are arranged in a ring at equal intervals. The multiple lifting plates 53 are staggered with the ramp trough. The multiple lifting plates 53 are set inclined downwards. A limiting box 54 is provided on the top of the multiple lifting plates 53. The limiting box 54 is fixedly installed on the top of the crushing and washing box 1.

[0043] The rooted Polygonatum sibiricum carried by the conveyor belt 44 is concentrated at the position of the lifting plate 53 by the inclined trough. The rotation of the conveyor roller 43 drives the pulley 51 to make the synchronous belt 52 rotate synchronously. The rotation of the synchronous belt 52 drives multiple lifting plates 53 to sequentially move the rooted Polygonatum sibiricum upward.

[0044] like Figure 6 and Figure 7 As shown, a feeding trough 55 is provided on one side of the limiting box 54. The feeding trough 55 is rotatably installed on the top of the crushing and washing box 1. The feeding trough 55 is set in a horizontal state, and one end of the feeding trough 55 is away from the direction of the conveyor belt 44.

[0045] After the Polygonatum sibiricum on the multiple lifting plates 53 enters the feeding trough 55 and slides into the feeding trough 55, the Polygonatum sibiricum with roots can be sent back to the crushing and washing box 1 for cyclic crushing and washing through the feeding trough 55.

[0046] like Figure 6 and Figure 7 As shown, a turntable 56 is fixedly installed on the outer wall of the pulley 51. A pusher plate 57 is hinged to the outer wall of the eccentric part of the turntable 56. A horizontal pusher plate 58 is hinged to one side of the pusher plate 57. The horizontal pusher plate 58 is slidably installed on the top of the crushing and washing box 1. The horizontal pusher plate 58 is set in a horizontal state. A locking block 59 is fixedly installed on one end of the horizontal pusher plate 58. The top of one side of the locking block 59 is set in a sloping state. A belt support rod 510 is provided on the top of the locking block 59. The outer wall of the belt support rod 510 fits against the top of the locking block 59. The belt support rod 510 is fixedly installed on the outer wall of the feeding trough 55.

[0047] The rotation of pulley 51 drives turntable 56 to rotate synchronously, and the rotation of turntable 56 drives horizontal push plate 58 to move back and forth. Horizontal push plate 58 then pushes the locking block 59 to move back and forth. Locking block 59 then pushes up and releases the support rod 510, causing the support rod 510 to move up and down, that is, the feeding trough 55 shakes up and down, which facilitates the continuous forward feeding of material by the feeding trough 55.

[0048] In practical implementation, the rooted Polygonatum sibiricum carried by the conveyor belt 44 is concentrated at the position of the lifting plate 53 by the inclined trough. The rotation of the conveyor roller 43 drives the pulley 51 to make the synchronous belt 52 rotate synchronously. The rotation of the synchronous belt 52 drives multiple lifting plates 53 to sequentially carry the rooted Polygonatum sibiricum upward. The Polygonatum sibiricum carried by the multiple lifting plates 53 enters the feeding trough 55 and slides into the feeding trough 55. The rotation of the pulley 51 drives the turntable 56 to rotate synchronously. The rotation of the turntable 56 drives the horizontal push plate 58 to move back and forth. The horizontal push plate 58 pushes the locking block 59 to move back and forth. The locking block 59 pushes up and releases the support rod 510, so that the support rod 510 moves up and down. That is, the feeding trough 55 shakes up and down, which facilitates the continuous forward feeding of material in the feeding trough 55. Thus, the rooted Polygonatum sibiricum can be sent back to the crushing and washing box 1 for cyclic crushing and washing through the feeding trough 55.

[0049] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
