Description

Technical Field

[0001] This utility model relates to the field of air separation of Chinese medicinal materials, and in particular to an air separation device for screening Chinese medicinal materials. Background Technology

[0002] The Chinese medicinal herb sieving and air separation device is a piece of equipment used in the processing of Chinese medicinal herbs. It is mainly used to remove impurities and separate herbs of different densities to improve the purity and quality of the herbs. It combines air separation technology and is suitable for processing dried Chinese medicinal herbs, such as seeds, flowers, leaves, and rhizomes.

[0003] Existing Chinese medicinal herb screening and air separation devices cannot adjust the size of the blower outlet during use. The air volume is adjusted only by the blade speed. If the air volume is too small, it cannot effectively blow away light impurities in the medicinal materials, resulting in substandard cleanliness. If the air volume is too large, it may blow away small particles or low-density medicinal parts by mistake, causing waste of the effective components of the medicinal materials.

[0004] Therefore, in view of the problem that the existing Chinese medicinal material screening and air separation devices cannot adjust the size of the fan outlet and only control the air volume by adjusting the blade speed, resulting in low flexibility, there is an urgent need to design a new type of Chinese medicinal material screening and air separation device. Utility Model Content

[0005] In order to overcome the problem that the existing Chinese medicinal material screening and air separation device cannot adjust the size of the fan outlet and only controls the air volume by adjusting the blade speed, which has low flexibility.

[0006] The technical solution of this utility model is as follows: a Chinese medicinal material screening and air separation device, including an installation frame; it also includes limit rods, blocks, racks, a fixed seat, a first drive motor and a toothed column. An air chamber is provided on the left side of the upper surface of the installation frame. Two symmetrical limit rods are installed on the upper surface of the installation frame at the air outlet of the air chamber. Blocks are slidably connected to the outer surfaces of the two limit rods. A rack is installed in the middle of the left side surface of the block. A fixed seat is installed on the right side of the upper surface of the air chamber. A first drive motor is provided on the front surface of the fixed seat. A toothed column is connected to the output end of the first drive motor. The toothed column meshes with the rack.

[0007] Preferably, by setting a first drive motor, its output end can drive the gear column to rotate during operation. When the gear column rotates, it can drive the meshing rack to move up and down, thereby causing the stop block to slide up and down on the outer surface of the limit rod. This adjusts the air outlet area of ​​the air chamber, thereby compressing the airflow and improving the overall flexibility of the device. This solves the problem that existing Chinese herbal medicine screening and air separation devices cannot adjust the size of the fan outlet, and the air volume is adjusted only by the blade speed. If the air volume is too small, it cannot effectively blow away light impurities in the herbs, resulting in substandard cleanliness. If the air volume is too large, it may blow away small particles or low-density medicinal parts, resulting in waste of the effective components of the herbs.

[0008] Preferably, four support rods arranged in a rectangular array are installed on the upper surface of the mounting frame at the right side of the air chamber. The top of the support rods is connected to a feeding frame. A first receiving frame is set at the bottom of the mounting frame on the ground, and a second receiving frame is placed at the right side of the first receiving frame on the ground.

[0009] Preferably, a first drive disc is installed at the front end of the blade drive shaft of the wind turbine, and a second drive motor is installed on the left side of the front side of the inner surface of the mounting frame. The output end of the second drive motor passes through the front side wall of the mounting frame and is connected to the second drive disc. A belt is sleeved on the outer surface of the first and second drive discs.

[0010] Preferably, a mounting bracket is provided on the lower part of the front surface of the air chamber. The inner surface of the mounting bracket is rotatably connected to the left and right sides with a double-acting screw. The outer surface of the double-acting screw is threadedly connected to two symmetrical movable seats. The front surface of the movable seats is provided with a limit component.

[0011] Preferably, the limiting assembly includes a connecting rod, a limiting roller, and a positioning sleeve; the connecting rod is mounted on the front surface of the movable seat, the outer surface of the connecting rod is rotatably connected to the limiting roller, and positioning sleeves are provided on both the front and rear sides of the limiting roller on the outer surface of the connecting rod.

[0012] Preferably, a knob is installed on the right side surface of the mounting bracket, and the left end of the knob passes through the right side wall of the mounting bracket and is connected to the right end of the bidirectional lead screw.

[0013] Preferably, the bottom surface of the mounting frame is provided with support legs at the corners, and the bottom of the support legs is provided with casters.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a first drive motor, its output end can drive the gear column to rotate. Since the rack and gear column mesh, the rotation of the gear column can drive the rack to move up and down. The rack will then drive the stop block to slide up and down on the outer surface of the limit rod, thereby adjusting the air outlet area of ​​the air chamber, thereby compressing the airflow and improving the overall flexibility of the device. This solves the problem that the air outlet of the blower in the existing Chinese herbal medicine screening and air separation device cannot be adjusted in size, and its air volume is only adjusted by the blade speed. If the air volume is too small, it cannot effectively blow away the light impurities in the herbs, resulting in substandard cleanliness. If the air volume is too large, it may blow away small particles or low-density medicinal parts by mistake, resulting in the waste of effective ingredients in the herbs. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a traditional Chinese medicine sieving and air-separating device, including an installation frame 1; it also includes limit rods 3, blocks 4, racks 5, a fixed seat 6, a first drive motor 7, and a gear column 8. An air chamber 2 is provided on the left side of the upper surface of the installation frame 1. Two symmetrically arranged limit rods 3 are installed on the upper surface of the installation frame 1 at the air outlet of the air chamber 2. Blocks 4 are slidably connected to the outer surfaces of the two limit rods 3. A rack 5 is installed in the middle of the left side surface of the block 4. A fixed seat 6 is installed on the right side of the upper surface of the air chamber 2. The front surface of the fixed base 6 is provided with a first drive motor 7. The output end of the first drive motor 7 is connected to a gear column 8, which meshes with a rack 5. By setting the first drive motor 7, its output end can drive the gear column 8 to rotate during operation. When the gear column 8 rotates, it can drive the rack 5 that it meshes with to move up and down, thereby driving the stop block 4 to slide up and down on the outer surface of the limit rod 3. This adjusts the air outlet area of ​​the air chamber 2, thereby compressing the airflow and improving the overall flexibility of the device.

[0023] Please see Figures 1-4 In this embodiment, four support rods 9 arranged in a rectangular array are installed on the upper surface of the mounting frame 1, located on the right side of the air chamber 2. A feeding frame 10 is connected to the top of the support rods 9. A first receiving frame 11 is located at the bottom of the mounting frame 1, and a second receiving frame 12 is placed on the right side of the first receiving frame 11. By setting up the feeding frame 10, during equipment operation, medicinal herbs can be poured into the feeding frame 10 for material discharge. Lighter impurities will fall into the second receiving frame 12, while the medicinal herbs will fall into the first receiving frame 11, thus achieving sorting. A first transmission disc 13 is installed at the front end of the blade drive shaft of the air chamber 2. A second drive motor 14 is installed on the left side of the front of the inner surface of the mounting frame 1. The output end of the second drive motor 14 passes through the front wall of the mounting frame 1 and is connected to a second transmission disc 15. 3. A belt 16 is fitted on the outer surface of the second transmission disc 15. By setting a second drive motor 14, its output end can drive the second transmission disc 15 to rotate during operation, thereby driving the first transmission disc 13 to rotate through the linkage of the belt 16, so that the blades inside the air chamber 2 rotate to blow air. A mounting bracket 17 is set at the lower position of the front surface of the air chamber 2. The inner surface of the mounting bracket 17 is rotatably connected to the left and right sides of the left and right sides. The outer surface of the double-sided screw 18 is threadedly connected to two symmetrical moving seats 19. The front surface of the moving seats 19 is provided with a limit component. By setting the double-sided screw 18, when rotating, it can drive the two moving seats 19 that are threaded with it to move synchronously in opposite directions, thereby adjusting the distance of the limit component so that it can fit with the belt 16 and prevent the belt 16 from becoming loose.

[0024] Please see Figures 1-4In this embodiment, the limiting assembly includes a connecting rod 201, a limiting roller 202, and a positioning sleeve 203. The connecting rod 201 is mounted on the front surface of the movable seat 19. The limiting roller 202 is rotatably connected to the outer surface of the connecting rod 201. Positioning sleeves 203 are provided on both the front and rear sides of the limiting roller 202 on the outer surface of the connecting rod 201. By setting the limiting roller 202, the limiting roller 202 can rotate on the outer surface of the connecting rod 201. Therefore, when the belt 16 is running, there is rolling friction between the limiting roller 202 and the belt 16, which can effectively... To reduce wear on the belt 16, a knob 21 is installed on the right side surface of the mounting bracket 17. The left end of the knob 21 passes through the right side wall of the mounting bracket 17 and connects to the right end of the bidirectional lead screw 18. By setting the knob 21, it is easy for the operator to rotate the bidirectional lead screw 18, which improves convenience. Support legs 22 are set at the corners of the bottom surface of the mounting frame 1. Universal wheels 23 are set at the bottom of the support legs 22. By setting the support legs 22 and universal wheels 23, it is easy for the operator to move the entire device, which improves convenience.

[0025] During operation, by setting up the feeding frame 10, Chinese medicinal materials can be poured into the feeding frame 10 for material discharge. Lighter impurities will fall into the second receiving frame 12, while the medicinal materials will fall into the first receiving frame 11, thus achieving sorting. By setting up the second drive motor 14, its output end can drive the second transmission disc 15 to rotate during operation, which in turn drives the first transmission disc 13 to rotate through the linkage of the belt 16, thereby causing the blades inside the air chamber 2 to rotate, thus blowing air. By setting up the bidirectional lead screw 18, when rotating, it can drive the screw threadedly engaged with it. The two movable seats 19 move synchronously in opposite directions to adjust the distance of the limiting components so that they can fit against the belt 16 and prevent the belt 16 from becoming loose. By setting the limiting roller 202, the limiting roller 202 can rotate on the outer surface of the connecting rod 201. Thus, when the belt 16 is running, the limiting roller 202 and the belt 16 have rolling friction, which can effectively reduce the wear on the belt 16. By setting the knob 21, the operator can easily rotate the bidirectional lead screw 18, which improves convenience. By setting the support legs 22 and universal wheels 23, the operator can easily move the entire device, which improves convenience.

[0026] Through the above steps, by setting the first drive motor 7, its output end can drive the gear column 8 to rotate. Since the rack 5 meshes with the gear column 8, the rotation of the gear column 8 can drive the rack 5 to move up and down. The rack 5 will then drive the stop block 4 to slide up and down on the outer surface of the limit rod 3, thereby adjusting the air outlet area of ​​the air chamber 2, thereby compressing the airflow and improving the overall flexibility of the device. This solves the problem that the existing Chinese herbal medicine screening and air separation device cannot adjust the size of the fan outlet when in use, and its air volume is only adjusted by the blade speed. If the air volume is too small, it cannot effectively blow away the light impurities in the medicinal materials, resulting in substandard cleanliness. If the air volume is too large, it may blow away small particles or low-density medicinal parts by mistake, causing waste of the effective components of the medicinal materials.
