Description

Technical Field

[0001] The utility model relates to the technical field of waste chip screening, in particular to a waste chip screening device for dried Chinese medicinal materials. Background Art

[0002] The dried Chinese medicinal materials may contain some waste chips, impurities, incomplete fragments, etc. These substances will affect the purity and quality of the medicinal materials. Through the waste chip screening device for dried Chinese medicinal materials, the waste chips, impurities, etc. in the dried Chinese medicinal materials can be separated out, and these impurities can be removed to ensure the purity of the medicinal materials and improve the quality of Chinese medicinal materials.

[0003] At present, the existing waste chip screening device for dried Chinese medicinal materials cannot prevent the accumulation of waste chips during the screening process, resulting in the blockage of the sieve holes, reducing the continuity and efficiency of the waste chip screening of Chinese medicinal materials, and affecting the product quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that the accumulation of waste chips cannot be prevented during the screening process, resulting in the blockage of the sieve holes, reducing the continuity and efficiency of the waste chip screening of Chinese medicinal materials, and affecting the product quality, and to propose a waste chip screening device for dried Chinese medicinal materials.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A waste chip screening device for dried Chinese medicinal materials, comprising:

[0007] A support frame and a box body, wherein a vibrator is fixedly arranged at the bottom of the box body;

[0008] A screening mechanism, which is arranged in the box body and is used for screening waste chips of different specifications of Chinese medicinal materials;

[0009] A knocking mechanism, which is arranged in the box body and is used for knocking the components inside the screening mechanism;

[0010] A support assembly, which is arranged on the support frame and is used for supporting the device.

[0011] In a possible design, the screening mechanism includes a first sieve mesh, a second sieve mesh and a third sieve mesh which are fixedly arranged in the box body from top to bottom in sequence. A first discharge rack is fixedly communicated with one side of the box body at the position of the first sieve mesh, a second discharge rack is fixedly communicated with one side of the box body at the position of the second sieve mesh, a third discharge rack is fixedly communicated with one side of the box body at the position of the third sieve mesh, and a slag discharge pipe is fixedly communicated with the bottom of the box body.

[0012] In a possible design, the knocking mechanism includes two rotating rods longitudinally and rotatably arranged on both sides of the inner wall of the box body. Two cams are respectively fixedly arranged on the outer parts of the two rotating rods. The two cams on the same rotating rod are staggeredly arranged. One rotating rod is located between the first sieve and the second sieve, and the other rotating rod is located between the second sieve and the third sieve. One ends of the two rotating rods located outside the box body are respectively fixedly provided with a driving synchronous pulley and a driven synchronous pulley. The driving synchronous pulley and the driven synchronous pulley are externally sleeved with the same synchronous belt. One side of the box body is fixedly provided with a motor, and one end of the output shaft of the motor is fixedly connected to one of the rotating rods.

[0013] In a possible design, the support assembly includes four fixing brackets fixedly arranged at the four corners of the support frame in a rectangular shape. Support rods are rotatably arranged inside the four fixing brackets. One ends of the four support rods are all slidably provided with sliding rods. One ends of the four sliding rods are all threadedly connected with threaded rods. The top ends of the threaded rods are fixedly provided with hand wheels, and the bottom ends of the threaded rods are rotatably provided with support pads.

[0014] In a possible design, the aperture of the first sieve is larger than that of the second sieve, and the aperture of the second sieve is larger than that of the third sieve.

[0015] In a possible design, four springs are fixedly arranged at the top of the support frame in a rectangular shape. Four connecting frames are fixedly arranged on both sides of the box body in a rectangular shape. The top parts of the four springs are respectively fixedly connected to the four connecting frames.

[0016] In a possible design, four universal brake wheels are fixedly arranged at the bottom of the support frame in a rectangular shape.

[0017] In a possible design, a feed hopper is fixedly arranged at the top of the box body, and the feed hopper is communicated with the box body.

[0018] In a possible design, a distance measuring sensor is installed on the support frame. The distance measuring sensor and the motor are both connected to a controller. When the distance measuring sensor detects that the box body is moving from a high position to a low position, the motor drives the cam to knock on the sieve.

[0019] In this application, when starting to use, first move the device to the position where it is needed through the universal brake wheels, and then lock it through the locking mechanism on the universal brake wheels to complete the positioning of the device. Then, power on the device, and then deploy the four support rods respectively and pull out the sliding rod from the support rod. When the sliding rod extends to an appropriate length, rotate the handwheel in sequence. By rotating the handwheel, drive the threaded rod to move downward in the sliding rod until the support pad abuts against the ground. When the ground is uneven, the length of the threaded rod can be continuously adjusted by rotating the handwheel according to the ground conditions, so that the threaded rod continues to rotate and extend and abuts against the ground through the support pad to raise one corner of the device, so that the whole device maintains a horizontal and stable state. The support pad contacts the ground, which can increase the friction and prevent the device from sliding during operation;

[0020] Then pour the dried Chinese herbal medicine waste into the box through the feed hopper. The design of the feed hopper facilitates the centralized feeding of the Chinese herbal medicine waste and ensures that the Chinese herbal medicine waste can smoothly enter the box for screening. Then start the vibrator and ensure that the vibrator is in good working condition. When the vibrator works, the Chinese herbal medicine waste is gradually screened by the first sieve, the second sieve and the third sieve in the box. Since the aperture of the first sieve is the largest, the larger particles of Chinese herbal medicine waste are first screened out and discharged and collected through the first discharge rack. Then, the medium-sized particles of Chinese herbal medicine waste are screened by the second sieve and discharged and collected by the second discharge rack. Finally, the smallest particles of Chinese herbal medicine waste are screened by the third sieve and discharged and collected by the third discharge rack. The fine particle residues that cannot pass through the third sieve fall to the bottom of the box and are discharged and collected through the slag discharge pipe;

[0021] During the screening process, start the motor at the same time. The output shaft of the motor drives one of the rotating rods and the cam on it to rotate. While the rotating rod rotates, it drives the driving synchronous pulley to rotate synchronously. While the driving synchronous pulley rotates, it drives the driven synchronous pulley to rotate through the synchronous belt. While the driven synchronous pulley rotates, it drives the rotating rod and the cam on it to rotate synchronously, and then drives the two rotating rods to rotate between the first sieve and the second sieve and between the second sieve and the third sieve respectively. The cam on the rotating rod continuously knocks the three sieves as the rotating rod rotates, and knocking the three sieves can prevent the Chinese herbal medicine waste of different sizes from accumulating on the sieves and blocking the sieve holes, ensuring the smooth progress of the screening process.

[0022] The utility model has the following beneficial effects:

[0023] In the present utility model, through the setting of the screening mechanism, a first sieve, a second sieve, and a third sieve are arranged inside the box body, and are supplemented with corresponding first discharge racks, second discharge racks, third discharge racks, and slag discharge pipes, realizing the automated and efficient grading screening of the waste scraps of traditional Chinese medicinal materials after drying. This not only facilitates the centralized feeding and smooth screening of the waste scraps of traditional Chinese medicinal materials, but also ensures the effective separation of the waste scraps of traditional Chinese medicinal materials in the box body through the gradually stepped sieves, accurately discharging and collecting the waste scraps of traditional Chinese medicinal materials of different sizes, and simultaneously discharging fine residues, greatly improving the screening efficiency and accuracy, reducing manual intervention, and bringing significant production benefits to the traditional Chinese medicinal materials processing industry;

[0024] In the present utility model, through the setting of the knocking mechanism, the motor drives the rotating rod and the cam thereon to rotate, continuously knocking the first sieve, the second sieve, and the third sieve, effectively preventing the accumulation of waste scraps of traditional Chinese medicinal materials on the sieves and the blockage of the sieve holes, ensuring the continuity and efficiency of the screening process, and improving the smoothness and product quality of the screening of waste scraps of traditional Chinese medicinal materials;

[0025] In the present utility model, through the setting of the support assembly, by unfolding the support rods and adjusting the lengths of the sliding rods and threaded rods, it can easily adapt to uneven ground and achieve the horizontal and stable support of the device. The support pads not only enhance the friction with the ground and prevent sliding during the working process, but also further improve the stability of the overall structure, ensuring the smooth progress of the screening operation.

[0026] In the present utility model, through the setting of the knocking mechanism, it effectively prevents the accumulation of waste scraps of traditional Chinese medicinal materials on the sieves and the blockage of the sieve holes, ensuring the continuity and efficiency of the screening process, and improving the smoothness and product quality of the screening of waste scraps of traditional Chinese medicinal materials.

[0027] In the present utility model, the movement of the box body is detected by the distance measuring sensor. When the box body moves from a high position to a low position, the traditional Chinese medicinal materials on each sieve are in a falling state, and the traditional Chinese medicinal materials do not directly contact the respective sieves. At this time, the controller controls the motor to drive the cam to rotate to knock the sieves, which can not only clean the waste scraps of traditional Chinese medicinal materials on each sieve, but also will not affect other intact traditional Chinese medicinal materials.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0034] Embodiment 1

[0035] Refer to Figures 1-4 , a screening device, including:

[0036] A support frame 1, a box body 3, a vibrator 11 (model can be: ZFB / LZF-3), a screening mechanism, a knocking mechanism, a support assembly, etc. The support frame 1 stably supports the entire device. The box body 3 is fixed on the support frame 1 and is internally provided with a screening mechanism and a knocking mechanism for finely screening and cleaning the waste chips after drying of Chinese medicinal materials. The vibrator 11 generates vibrations to provide a vibration force to the box body 3 for subsequent vibration screening.

[0037] The screening mechanism is composed of a first sieve mesh 4, a second sieve mesh 5, and a third sieve mesh 6. These sieve meshes are fixedly arranged inside the box body 3 from top to bottom in sequence. The first sieve mesh 4 has the largest aperture and is used to screen out larger particle waste of traditional Chinese medicine. A first discharge rack 7 is correspondingly arranged beside it to discharge and collect the screened materials. The aperture of the second sieve mesh 5 is the second largest, which further subdivides the waste of traditional Chinese medicine and discharges and collects the screened materials through the second discharge rack 8. The third sieve mesh 6 has the smallest aperture and is used to screen out the smallest particle waste of traditional Chinese medicine and discharge and collect the screened materials through the third discharge rack 9. A slag discharge pipe 10 is arranged at the bottom of the box body 3 to discharge the fine residues that cannot pass through the third sieve mesh 6, thus realizing the automatic and efficient grading screening of the waste of traditional Chinese medicine after drying. It not only facilitates the centralized feeding and smooth screening of the waste of traditional Chinese medicine, but also ensures the effective separation of the waste of traditional Chinese medicine in the box body 3 through the sieve meshes step by step, accurately discharges and collects the waste of traditional Chinese medicine with different sizes respectively, and at the same time excludes the fine residues, greatly improving the screening efficiency and accuracy, reducing manual intervention, and bringing significant production benefits to the traditional Chinese medicine processing industry.

[0038] The knocking mechanism is composed of two rotating rods 12, cams 13, a motor 14, a synchronous belt 17, etc. The two rotating rods 12 are respectively arranged between the first sieve mesh 4 and the second sieve mesh 5 and between the second sieve mesh 5 and the third sieve mesh 6. Two staggered cams 13 are fixedly installed on each rotating rod 12. One of the rotating rods 12 is driven by the motor 14, and the two rotating rods 12 are synchronously rotated through the cooperation of the synchronous belt 17 with the driving synchronous pulley 15 and the driven synchronous pulley 16. When the motor 14 works, the rotating rod 12 drives the cam 13 to rotate, continuously knocking the sieve mesh, effectively preventing the waste of traditional Chinese medicine after drying from blocking the sieve mesh holes and improving the screening efficiency.

[0039] The support assembly is composed of four fixing frames 19, support rods 20, sliding rods 21, threaded rods 22, handwheels 23, support pads 24, etc. The fixing frames 19 are fixed at the four corners of the support frame 1. The support rods 20 are connected to the fixing frames 19 in a rotating manner. The sliding rods 21 are slidably arranged at one end of the support rods 20. The threaded rods 22 are threadedly connected to the sliding rods 21. A handwheel 23 is provided at the top for facilitating the adjustment of the height of the threaded rod 22, and a support pad 24 is connected to the bottom end to increase the stability. By rotating the handwheel 23, the length of the threaded rod 22 can be adjusted to adapt to different ground environments and realize the horizontal and stable support of the device.

[0040] This application can be used in the technical field of screening the waste of traditional Chinese medicine after drying, and can also be used in other fields applicable to this application.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, Embodiment 2 further includes: a waste residue screening device for Chinese medicinal materials after drying, which is applied to the technical field of waste residue screening for Chinese medicinal materials after drying. To reduce the impact of vibration during the screening process on the overall stability of the device, four springs 2 are also provided at the top of the support frame 1, which are connected to the box body 3 through a connecting frame, playing a role in buffering and shock absorption, and cooperating with the vibrator 11 to carry out the vibration screening work.

[0043] Four universal brake wheels 25 are provided at the bottom of the support frame 1, which is convenient for the device to be fixed after being moved to a designated position, improving the flexibility of use.

[0044] A feed hopper 18 is provided at the top of the box body 3, which is communicated with the inside of the box body, facilitating the feeding of the waste residue of Chinese medicinal materials to be screened into the device for screening treatment.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the vibrator 11 and the motor 11 are common knowledge, and they both belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.

[0046] Embodiment 3

[0047] When the distance between the box body 3 and the support frame 1 reaches a preset high point, the distance measuring sensor will detect this change and send a signal to the controller. After receiving the signal from the distance measuring sensor, the controller will immediately execute a preset program (the existing program for controlling start and stop), driving the motor 14 to start working. After the motor 14 starts, it will drive the cam 13 to rotate. As the cam 13 rotates, its contour will continuously contact the sieve mesh, thereby generating periodic knocking or vibration. This periodic knocking or vibration will act on the sieve mesh, promoting the separation of the blocked materials on the sieve mesh.

[0048] When the distance between the box body 3 and the support frame 1 reaches a preset low point, the distance measuring sensor will detect this change and send a signal to the controller. After receiving the signal from the distance measuring sensor, the controller will immediately execute a preset program or logic, driving the motor 14 to stop working. After the motor 14 stops, it will cause the cam 13 to brake, thereby stopping knocking on the sieve mesh. Repeating the above steps, the Chinese medicinal materials on the sieve mesh will knock on the sieve mesh in a flying state, thereby improving the situation of sieve mesh blockage.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
