Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a sieving device for processing traditional Chinese medicine decoction pieces. Background Technology

[0002] As an important component of the traditional Chinese medicine (TCM) industry, the quality of prepared herbal medicines directly affects the clinical efficacy of TCM treatments. With the rapid development of the TCM industry and the increasing demand for health and wellness, the market demand for prepared herbal medicines continues to grow. In the production process of prepared herbal medicines, the powder sieving stage is one of the key steps to ensure the quality and efficacy of the herbs.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216779015U, which discloses a sieving device for traditional Chinese medicine decoction pieces. The device includes a base, a sieving box fixedly mounted on the top of the base, a feeding channel fixedly mounted on the top of the sieving box, a motor fixedly mounted on one side of the sieving box, a spiral pulverizing blade at the motor's output end, and a screening plate fixedly mounted on the inner wall of the sieving box. The motor drives the spiral pulverizing blade to rotate, pulverizing the traditional Chinese medicine decoction pieces fed into the sieving box.

[0004] The aforementioned device feeds materials through a feeding channel. During operation, the powder inevitably diffuses outward through the feed inlet due to vibration, which will affect the surrounding environment and increase the workload of subsequent cleaning. There is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a sieving device for processing Chinese herbal medicine slices to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sieving device for processing Chinese herbal medicine slices, comprising a sieving chamber, a feeding assembly installed on the top of the sieving chamber, the feeding assembly including a screw conveyor fixedly installed on the outer wall of the top of the sieving chamber, the screw conveyor being horizontally arranged, the outlet of the screw conveyor being arranged facing the sieving chamber, a discharge pipe being rotatably connected to the top of the sieving chamber, and the middle part of the discharge pipe being inclined, the discharge pipe being rotatably sleeved outside the outlet of the screw conveyor, and a funnel-shaped storage hopper being provided on one side of the top of the screw conveyor.

[0007] The system effectively blocks the feed channel by controlling the raw materials, preventing dust from escaping and distributing the powder for faster sieving. This avoids dust accumulation and reduced sieving efficiency. When the screw conveyor is started, the screw pulls the powder into the discharge pipe, where it falls through an opening at the bottom. The powder inside the screw conveyor forms a layer, preventing dust from overflowing. After the raw materials are conveyed, the herbal dust enters the discharge pipe and must pass through the screw conveyor to overflow. Due to the screw, the dust escape path is more complex and longer. During this time, the dust gradually settles inside the screw conveyor and cannot escape.

[0008] As a further preferred embodiment of this technical solution, a second bevel gear is coaxially fixed at one end of the screw rod inside the screw conveyor, a gear rod is rotatably connected to the top outer wall of the powder screening chamber through a mounting bracket, a first bevel gear that meshes with the second bevel gear is coaxially fixed at the top end of the gear rod, and a toothed ring is coaxially fixed to the outside of the discharge pipe, with the gear rod meshing with the toothed ring.

[0009] As a further preferred embodiment of this technical solution, a sieving assembly is installed inside the sieving chamber, and the sieving assembly is located below the discharge pipe.

[0010] As a further preferred embodiment of this technical solution, the powder screening assembly includes four connecting plates fixedly connected inside the powder screening chamber. Each of the four connecting plates has a spring fixedly connected to its bottom outer wall. The bottom end of each of the four springs is fixedly connected to the same screening frame, and the screening frame is inclined.

[0011] As a further preferred embodiment of this technical solution, a baffle is rotatably connected to one end of the bottom of the screening frame, and both ends of the baffle are arc-shaped, with the center of the arc collinear with the rotation axis of the baffle. A temporary storage chamber is provided on both outer walls of the baffle. A motor is fixedly installed on one outer wall of the screening frame, and the output end of the motor is coaxially fixed with one end of the rotation axis of the baffle.

[0012] Because the screening frame is tilted, the large particles that are intercepted move downwards due to vibration and then enter a temporary storage chamber inside the baffle. After the device has been running for a period of time, the motor is started to drive the baffle to rotate half a turn, and the opening of the temporary storage chamber containing the medicinal materials changes to face downwards. The temporarily stored medicinal materials fall into the discharge port along the slope, allowing the device to continue operating more quickly.

[0013] As a further preferred embodiment of this technical solution, a discharge port is provided on one side of the outer wall of the powder screening chamber, and a baffle is slidably inserted inside the discharge port, and the discharge port surrounds the opening of one of the temporary storage chambers.

[0014] As a further preferred embodiment of this technical solution, a collection box is slidably inserted into the bottom of one side of the outer wall of the powder screening chamber, and the collection box is located directly below the screening frame.

[0015] This utility model provides a sieving device for processing Chinese herbal medicine slices, which has the following beneficial effects:

[0016] (1) This utility model, by setting up a feeding component, can block the feeding channel through the raw material, effectively preventing dust from escaping outwards, and can also distribute the position of the powder, so that the powder can be screened more quickly, avoiding accumulation in one place and affecting the screening efficiency. When the screw conveyor is started, the screw rod inside it drives the powder into the discharge pipe, and then falls through the opening at the bottom of the discharge pipe. The powder inside the screw conveyor can form a partition to prevent dust from overflowing. After the raw material is conveyed, the Chinese medicine dust enters the discharge pipe and needs to be conveyed by the screw conveyor. The dust will overflow outwards. Due to the presence of the screw, the dust overflow channel is more complex and longer. During the time the dust dissipates in the channel, it will gradually settle into the inside of the screw conveyor and cannot overflow. When the screw rotates inside the screw conveyor, the second bevel gear is driven to rotate synchronously. The second bevel gear drives the first bevel gear to rotate through meshing. The first bevel gear drives the gear rod to rotate. The gear rod drives the discharge pipe to rotate through the toothed ring it meshes with. The area of ​​the powder landing point will be greatly increased, avoiding the powder at the bottom from affecting the screening of the powder at the top when the powder accumulates in one place.

[0017] (2) By setting up a powder screening component, since the screening frame is tilted, the large particles that are intercepted move downwards due to vibration and then enter a temporary storage chamber of the baffle. After the device has been running for a period of time, the motor is started to drive the baffle to rotate half a circle, and the opening of the temporary storage chamber containing the medicinal materials changes downwards. The temporarily stored medicinal materials fall into the discharge port along the slope, so that the device can continue to run faster. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown in this embodiment, a traditional Chinese medicine decoction piece processing sieving device includes a sieving chamber 1. A feeding assembly 5 is installed on the top of the sieving chamber 1. The feeding assembly 5 includes a screw conveyor 501 fixedly installed on the outer wall of the top of the sieving chamber 1. The screw conveyor 501 is set in a horizontal state, and the outlet of the screw conveyor 501 is set towards the sieving chamber 1. A discharge pipe 503 is rotatably connected to the top of the sieving chamber 1, and the middle part of the discharge pipe 503 is set at an inclination. The discharge pipe 503 is rotatably sleeved outside the outlet of the screw conveyor 501. A funnel-shaped storage hopper 502 is set on one side of the top of the screw conveyor 501.

[0025] Inside the screw conveyor 501, one end of the screw rod is coaxially fixed with a bevel gear 507. The top outer wall of the screening chamber 1 is rotatably connected to a gear rod 505 via a mounting bracket. The top end of the gear rod 505 is coaxially fixed with a bevel gear 506 that meshes with the bevel gear 507. A toothed ring 504 is coaxially fixed to the outside of the discharge pipe 503. The gear rod 505 meshes with the toothed ring 504.

[0026] When the screw conveyor 501 is started, the screw rod inside it carries the powder into the discharge pipe 503, and then it falls through the opening at the bottom of the discharge pipe 503. The powder inside the screw conveyor 501 can form a layer to prevent dust from overflowing. After the raw materials are conveyed, the Chinese medicine dust enters the discharge pipe 503 and needs to pass through the screw conveyor 501 to overflow. Due to the presence of the screw rod, the dust overflow channel is more complex and longer. During the time it escapes in the channel, the dust will gradually settle into the screw conveyor 501 and cannot overflow. When the screw rod inside the screw conveyor 501 rotates, the bevel gear 2 507 is driven to rotate synchronously. The bevel gear 2 507 drives the bevel gear 1 506 to rotate through meshing. The bevel gear 1 506 drives the gear rod 505 to rotate. The gear rod 505 drives the discharge pipe 503 to rotate through the gear ring 504 that meshes with it. The area of ​​the powder landing point will be greatly increased, preventing the powder at the bottom from affecting the screening of the powder at the top when the powder accumulates in one place.

[0027] like Figure 2 and Figure 3 As shown, a sieving assembly 6 is installed inside the sieving chamber 1, and the sieving assembly 6 is located below the discharge pipe 503.

[0028] The powder screening assembly 6 includes four connecting plates 601 fixedly connected inside the powder screening chamber 1. Each of the four connecting plates 601 has a spring 602 fixedly connected to its bottom outer wall. The bottom end of each of the four springs 602 is fixedly connected to the same screening frame 603, and the screening frame 603 is inclined.

[0029] A baffle 604 is rotatably connected to one end of the bottom of the screening frame 603. Both ends of the baffle 604 are arc-shaped, and the center of the arc is collinear with the rotation axis of the baffle 604. A temporary storage chamber 605 is provided on both outer walls of the baffle 604. A motor 606 (a worm gear motor, preferably ExdIICT4-W, with stable vibration resistance in dusty and humid environments) is fixedly installed on one outer wall of the screening frame 603. The output end of the motor 606 is coaxially fixed with one end of the rotation axis of the baffle 604. A through hole for wire installation is provided on the side of the screening chamber 1 (not shown in the figure).

[0030] When the powder falls into the screening frame 603, the operator starts the vibrator at its bottom. The screening frame 603 is connected to the connecting plate 601 via the spring 602, and the screening frame 603 will be driven to vibrate rapidly, and the powder will be screened quickly. Since the screening frame 603 is tilted, the large particles that are intercepted move downwards due to the vibration and then enter a temporary storage chamber 605 inside the baffle 604. After the device has been running for a period of time, the motor 606 is started to drive the baffle 604 to rotate half a turn. The opening of the temporary storage chamber 605 containing the medicinal materials changes downwards, and the temporarily stored medicinal materials fall into the discharge port 2 along the slope, so that the device can continue to operate more quickly.

[0031] like Figure 1 and Figure 2 As shown, a discharge port 2 is provided on one side of the outer wall of the powder screening chamber 1. A baffle 3 is slidably inserted inside the discharge port 2, and the discharge port 2 surrounds the opening of one of the temporary storage chambers 605, which can temporarily store the intercepted medicinal powder. After the work is completed, the baffle 3 is pulled out of the discharge port 2, and the intercepted medicinal materials will be quickly discharged.

[0032] like Figure 1 and Figure 2 As shown, a collection box 4 is slidably inserted into the bottom of one side of the outer wall of the powder sieving chamber 1. The collection box 4 is located directly below the sieving frame 603 and can collect the sieving powder.

[0033] This utility model provides a sieving device for processing Chinese herbal medicine slices, the specific working principle of which is as follows:

[0034] When the device is working, the powdered medicinal herbs to be screened are put into the storage hopper 502.

[0035] When the screw conveyor 501 is started, the screw rod inside it carries the powder into the discharge pipe 503, and then it falls through the opening at the bottom of the discharge pipe 503. The powder inside the screw conveyor 501 forms a layer to prevent dust from overflowing. After the raw materials are conveyed, the medicinal powder enters the discharge pipe 503 and needs to pass through the screw conveyor 501 before overflowing. Due to the presence of the screw rod, the dust overflow channel is more complex and longer. During the time it escapes in the channel, the dust will gradually settle into the screw conveyor 501 and cannot overflow. When the screw rod inside the screw conveyor 501 rotates, the bevel gear 2 507 is driven to rotate synchronously. The bevel gear 2 507 drives the bevel gear 1 506 to rotate through meshing. The bevel gear 1 506 drives the gear rod 505 to rotate. The gear rod 505 drives the discharge pipe 503 to rotate through the gear ring 504 that meshes with it. The powder falls at the designated point. The area will be greatly increased, avoiding the bottom powder from affecting the sieving of the top powder when the powder accumulates in one place. When the powder falls into the screening frame 603, the operator starts the vibrator at the bottom. The screening frame 603 is connected to the connecting plate 601 through the spring 602, and the screening frame 603 will be driven to vibrate rapidly, and the powder will be quickly screened. Since the screening frame 603 is tilted, the large particles that are intercepted move to the lower position due to vibration, and then enter a temporary storage chamber 605 of the baffle 604. After the device has been running for a period of time, the motor 606 is started to drive the baffle 604 to rotate half a turn. The opening of the temporary storage chamber 605 containing the medicinal materials changes to face downward. The temporarily stored medicinal materials fall into the discharge port 2 along the slope, so that the device can continue to operate more quickly. After the work is completed, the baffle 3 is pulled out of the discharge port 2, and the intercepted medicinal materials will also be quickly discharged.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
