[0002] Traditional Chinese medicine (TCM) decoction pieces are medicinal materials that have been processed according to TCM theory and methods and can be directly used in TCM clinical practice. In TCM theory, there are no absolute boundaries for TCM decoction pieces; they include sliced ​​medicinal herbs processed in some regions, whole medicinal herbs, and those processed through cutting or roasting.

[0003] In the process of processing medicinal slices, linear vibrating screens are required. By matching different screens, linear vibrating screens can screen out materials that meet the requirements and are of uniform size. When using linear vibrating screens, raw materials need to be added through the feed inlet before screening. However, existing linear vibrating screens usually cannot adjust the feed rate. During use, a lot of raw materials fall directly onto the linear vibrating screen through the feed inlet, which can easily cause accumulation and blockage, thereby affecting the subsequent screening effect.

Detailed Implementation

[0033] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1-10 As shown, this utility model provides a linear vibrating screen, comprising:

[0035] The linear vibrating screen body 1 has a support frame 11 at its bottom. The support frame 11 can provide stable support for the linear vibrating screen body 1. Specifically, the linear vibrating screen body 1 is a multi-stage linear vibrating screen. The multi-stage linear vibrating screen has at least two layers of filter plates inside its shell, which can filter the medicinal slices multiple times, resulting in better filtration of the medicinal slices.

[0036] Mounting box 2 is fixedly installed on the top left side of the linear vibrating screen body 1;

[0037] The circular block 3 is rotatably connected to the inner walls of the front and rear sides of the mounting box 2, respectively. An assembly groove 31 is opened in the center of the circular block 3, and four sliding grooves 32 are evenly opened around the periphery of the circular block 3. All four sliding grooves 32 are connected to the assembly groove 31.

[0038] There are four sealing plates 4, which are slidably and sealingly assembled into the four sliding grooves 32 respectively.

[0039] The drive mechanism 5 is installed inside the assembly slot 31 and is used to drive the four closed plates 4 to move closer or further apart from each other. The drive mechanism 5 includes a threaded rod 51, one end of which is rotatably connected to the middle of the front inner wall of the assembly slot 31, and the other end of which extends out of the circular block 3 and is fixedly mounted with a turntable 56. An opening matching the position of the circular block 3 is opened on the rear side of the mounting box 2. An assembly block 52 is threadedly connected to the periphery of the threaded rod 51. An adjusting block 53 is fixedly mounted on the rear side of each assembly block 52. The side of each of the four adjusting blocks 53 away from the assembly block 52 is inclined toward the four closed plates 4. A sliding groove 531 is opened on one side of each of the four adjusting blocks 53. A moving block 54 is slidably assembled inside each of the four sliding grooves 531. A connecting block 55 is fixedly mounted on the side of each of the four closed plates 4 that is close to each other. One side of each of the four connecting blocks 55 is fixedly connected to one side of each of the four moving blocks 54.

[0040] In the initial state, when the turntable 56 is not rotating, the positions of the four adjusting blocks 53 are fixed because the assembly block 52 is threadedly connected to the threaded rod 51. Since the four closing plates 4 can only slide within the four sliding grooves 32, the four moving blocks 54 cannot slide within the four sliding grooves 531 after the adjusting blocks 53 are fixed. The positions of the four closing plates 4 are fixed. When it is necessary to screen the medicinal slices, the medicinal slices are poured into the mounting box 2. The gap between the two guide plates 7 is equal to the width of the sliding groove 32. When the sliding groove 32 is not aligned with this gap, the circumference of the circular block 3 closes the gap, preventing the raw materials from falling out. The linear excitation is then activated. After the vibrating screen body 1 is activated, the motor 6 is started. The motor 6 drives the circular block 3 to rotate at a constant speed. When the sliding groove 32 is aligned with the two guide plates 7, it enters the sliding groove 32 due to gravity. The two arc plates 8 can enclose the circular block 3. When the raw material enters the sliding groove 32, the volume of the sliding groove 32 is fixed due to the closure of the sealing plate 4. When it rotates between the two arc plates 8, the medicinal slices will not be exposed. When the sliding groove 32 containing the medicinal slices is facing down, it will fall into the linear vibrating screen body 1 for vibration screening. This can realize the intermittent batch feeding of medicinal slices and avoid the accumulation and blockage of material caused by too much material falling at one time, which affects the screening of medicinal slices.

[0041] When screening different sized medicinal slices, the volume of each sliding groove 32 for loading can be adjusted, and the feeding speed can be adjusted according to processing requirements. When the volume needs to be adjusted, the operator rotates the turntable 56, which drives the threaded rod 51 to rotate. The threaded rod 51 drives the assembly block 52 to move. Since the closed plate 4 can only slide, as the adjusting block 53 moves, it drives the moving block 54 to move along the inclined direction of the sliding groove 531. When the moving block 54 moves from low to high or from high to low in the sliding groove 531, it will push the closed plate 4 to move, thereby realizing the adjustment of the volume of the sliding groove 32 for loading. This method can adjust multiple flower troughs 32 at the same time, which is simple and convenient to operate and further improves practicality.

[0042] A circular ring 33 is fixedly installed on the rear side of the circular block 3. The turntable 56 is located inside the circular ring 33. A gripping rod 57 is eccentrically arranged on the rear side of the turntable 56. Several insertion slots 34 are opened around the inner side of the circular ring 33. A toggle slot is opened on the rear side of the turntable 56. An opening communicating with the toggle slot is opened on the periphery of the turntable 56. A locking block 58 is slidably assembled inside the toggle slot. A spring 59 is fixedly installed at the bottom of the locking block 58. The lower end of the spring 59 is fixedly connected to the inner wall of the bottom side of the toggle slot. The upper side of the locking block 58 passes through the opening and extends into one of the insertion slots 34. A toggle piece 591 is fixedly installed on the rear side of the locking block 58.

[0043] Due to the vibration characteristics of the linear vibrating screen body 1, in order to prevent the threaded rod 51 from rotating under vibration, after the position of the closing plate is adjusted, the turntable 56 is limited by the connection between the locking block 58 and the insertion slot 34. Under the action of the spring 59, the turntable 56 will not rotate under vibration. When it is necessary to rotate the turntable 56, move the actuating piece 591 downward to drive the locking block 58 out of the connection with the insertion slot 34, and then hold the holding rod 57 to rotate the turntable 56. Afterwards, the locking block 58 can be reconnected to one of the insertion slots 34.

[0044] Motor 6 is fixedly installed on the front side of mounting box 2, and the output shaft of motor 6 is connected to the circular block 3 for transmission.

[0045] Two guide plates 7 are provided. The two guide plates 7 are fixedly installed on the inner walls of the left and right sides of the installation box 2 respectively. The two guide plates 7 are inclined towards the circular block 3 on the side closest to each other.

[0046] Two curved plates 8 are provided, and the two curved plates 8 are arranged in a mirror image distribution and assembled on the left and right sides inside the mounting box 2. The circular block 3 is located between the two curved plates 8.

[0047] A rectangular opening is provided on the rear side of the circular block 3, which is connected to one of the sliding grooves 32. An observation window 321 is provided inside the rectangular opening. The observation window 321 is provided to facilitate real-time viewing of the position of the closed plate 4 inside the sliding groove 32.

[0048] The device is used as follows:

[0049] In the initial state, the position of the closed plate 4 is adjusted according to the usage requirements. During adjustment, the turntable 56 is rotated, causing the threaded rod 51 to drive the assembly block 52 to move. When the assembly block 52 moves, it drives the four adjusting blocks 53 to move in unison. The tilt angle of the sliding groove 531 drives the four closed plates 4 to move away from or closer to each other. After the adjustment is completed, the medicinal slices are poured into the installation box 2. The motor 6 and the linear vibrating screen body 1 are started. After the motor 6 starts, it drives the circular block 3 to rotate. The circular block 3 rotates at a constant speed, causing the four sliding grooves 32 to align with the gaps between the two guide plates 7 in turn. When the sliding groove 32 containing the medicinal slices rotates to the bottom, it falls into the linear vibrating screen body 1 for screening. After screening, it is discharged through the outlet on the right side of the linear vibrating screen body 1. In this way, the medicinal slices can be poured into the installation box 2 in a concentrated manner, and then the medicinal slices can be introduced into the linear vibrating screen body 1 in batches. This avoids the accumulation and blockage of raw materials caused by too much material falling at one time, which would affect the subsequent screening effect.
