Description

Technical Field

[0001] The invention relates to the field of decoction slice Chinese medicinal material sorting, and specifically relates to decoction slice Chinese medicinal material sorting equipment. Background Art

[0002] Decoction slices are a kind of processed Chinese medicine products. Decoction slices of Chinese medicinal materials are Chinese medicinal materials that have been sliced ​​to facilitate weighing and use as medicine. The different parts of the original Chinese medicinal materials are different in size and thickness, and the size of the decoction slices after slicing is also different. For example, Chinese medicinal materials such as Sophora flavescens, so decoction slices of Chinese medicinal materials will be sorted and sorted into different specifications and grades.

[0003] Existing Chinese medicinal material sorting equipment for decoction pieces, for example, the air-throwing screening and sorting device for Chinese medicinal material processing proposed in patent application number "CN202110358388.2", uses structures such as a rectangular sorting box, a conveying roller, a projectile drum, a screening and collecting combination, and a discharging diversion combination. After the Chinese medicinal material decoction pieces contact the outer wall of the projectile drum, the high-speed rotating projectile drum will throw the Chinese medicine obliquely upward, and Chinese medicinal material decoction pieces of different weights are projected at different heights. Therefore, the screening and collecting combination is rotated and connected in the rectangular sorting box, and a vertical turntable is arranged on the screening and collecting combination. Axially and radially distributed guide pipes are arranged on the vertical turntable. The guide pipes are obliquely distributed, and one end of the guide pipe is rotatably connected to the collecting cylinder. The radially distributed guide pipes in the lower half of the vertical turntable will collect Chinese medicinal material decoction pieces of different heights, so that sorting and processing of Chinese medicinal material decoction pieces of different weights can be realized.

[0004] However, the existing technology has defects. The larger the size of the sliced ​​Chinese herbal medicine, the heavier it is, but the larger the cross-sectional area is. When the slices are thrown upward, the larger the cross-sectional area, the greater the air resistance they will withstand. The air resistance affects the height at which the slices are thrown. At the same time, factors such as the throwing angle of the slices will also affect the throwing height. Judging the throwing height of the slices based solely on weight will result in poor sorting of Chinese herbal medicines, and the air-throwing sorting effect is poor. Therefore, a Chinese herbal medicine sorting device for slices is proposed. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] A Chinese medicinal material sorting device for decoction pieces, such as Figure 1-Figure 6 As shown, it includes a machine base 1, and two groups of transmission rollers 2 are rotatably connected inside the machine base 1, and the two groups of transmission rollers 2 are commonly connected with a conveyor belt 3 for transmission. The inner walls of the conveyor belt 3 and the two ends of the transmission rollers 2 are driven by teeth meshing or friction transmission. The middle part of the conveyor belt 3 is not transmitted with the middle part of the transmission roller 2, and is only transmitted by the two sides and the transmission roller 2. The two groups of transmission rollers 2 are driven to rotate by external equipment, and the conveyor belt 3 is tightly installed between the two groups of transmission rollers 2. The rotation of the transmission roller 2 drives the conveyor belt 3 to run. Multiple groups of partitions 5 are fixedly connected to the conveyor belt 3, and the distances between adjacent partitions 5 are the same. Multiple groups of feeding ports 4 for pushing medicinal slices are opened through the conveyor belt 3, and the multiple groups of feeding ports 4 are respectively located between the multiple groups of partitions 5. A feeding port 4 is set between every two groups of partitions 5, and the partitions 5 separate the medicinal slices in different feeding ports 4.

[0030] A collecting seat 6 for collecting sorted medicinal slices is fixedly connected inside the machine base 1, and the collecting seat 6 is located inside the conveyor belt 3. A fine filter plate 8, a medium filter plate 9 and a large filter plate 10 are fixedly connected to the upper end of the collecting seat 6. The upper end surfaces of the fine filter plate 8, the medium filter plate 9 and the large filter plate 10 are all in close contact with the upper end of the inner wall of the conveyor belt 3. A bracket 16 is fixedly connected to one side of the machine base 1, and a top seat 17 is fixedly connected to the upper end of the bracket 16. A feeding mechanism 18 for adding material to the conveyor belt 3 is clamped on one side of the lower end of the top seat 17, and a stirring component for stirring the medicinal slices in the conveyor belt 3 is fixedly connected on the other side. When the conveyor belt 3 is running, the conveyor belt 3 slides relative to the upper end of the collecting seat 6, and the conveyor belt 3 and the upper end of the collecting seat 6 are in close contact with each other without any gap. The conveyor belt 3 drives the medicinal slices in the feed port 4 to slide on the collecting seat 6 and are sorted in sequence.

[0031] The feeding port 4 inside the conveyor belt 3 is driven by the transmission roller 2 to move on the upper end of the receiving seat 6, and the medicinal pieces are added to the feeding port 4 at one end of the receiving seat 6 by the feeding mechanism 18, and the upper end of the receiving seat 6 located below the feeding mechanism 18 is sealed. At this time, the medicinal pieces in the feeding port 4 located below the feeding mechanism 18 will not fall into the receiving seat 6, and the medicinal pieces in each group of feeding ports 4 pass through the fine filter plate 8, the medium filter plate 9 and the large filter plate 10 in turn, and are stirred by the stirring component. The dust and impurities inside the medicinal pieces are filtered out by the fine filter plate 8, the medicinal pieces of smaller size are filtered out by the medium filter plate 9, and the medicinal pieces of larger size pass through the large filter plate 10, thereby sorting fine particles, small-sized medicinal pieces and large-sized medicinal pieces. The equipment removes impurities and selects the medicinal pieces in grades without tossing the medicinal pieces, with fewer factors to consider. With the stirring component, the sorting efficiency is high and the effect is good.

[0032] like Figure 1-Figure 3 As shown, a side opening 31 is opened on one side of the machine base 1, and one side of the material receiving seat 6 is located in the side opening 31. Three groups of silos 7 are opened inside the material receiving seat 6. The fine filter plate 8, the medium filter plate 9 and the large filter plate 10 are respectively fixed to the upper end surfaces of the three groups of silos 7 by bolts. The upper surfaces of the fine filter plate 8, the medium filter plate 9 and the large filter plate 10 are flush with the upper surface of the material receiving seat 6, and the width of the feed port 4 is the same as the width of the silo 7.

[0033] Fine impurities, small-sized medicinal pieces and large-sized medicinal pieces enter three groups of silos 7 respectively.

[0034] like Figure 1-Figure 3 As shown, the material receiving seat 6 is fixedly connected to a side seat 11 on one side located in the side opening 31, and the interior of the side seat 11 is divided into three groups of collecting troughs 13 by two groups of separation plates 12. The three groups of collecting troughs 13 are respectively connected to the three groups of material bins 7, and the three groups of material bins 7 are vertically slidably connected to the interiors of the three groups of material bins 7. The material receiving plates 14 are installed perpendicular to the partition plate 5, and a pull rod 15 is commonly fixed to one side of the three groups of material receiving plates 14.

[0035] The impurities or medicinal pieces in the three groups of silos 7 enter the three groups of collecting troughs 13, which is convenient for packaging the medicinal pieces. During sorting, the collecting plate 14 is in contact with the innermost side wall of the silo 7. After the sorting is completed, there are medicinal pieces remaining in the silo 7. The pull rod 15 is pulled to drive the collecting plate 14 to slide in the silo 7, so that the collecting plate 14 is pulled out through the medicinal pieces or impurities in the silo 7 to prevent the medicinal pieces or impurities from remaining.

[0036] like Figure 1-Figure 5 As shown, the fine filter plate 8 , the medium filter plate 9 and the large filter plate 10 are all located on one side of the feeding mechanism 18 , the fine filter plate 8 is located between the feeding mechanism 18 and the medium filter plate 9 , and the medium filter plate 9 is located between the fine filter plate 8 and the large filter plate 10 .

[0037] The medicinal pieces first pass through the fine filter plate 8, then the medium filter plate 9, and finally the large filter plate 10, and are graded and processed in order, and the sorting is careful and accurate.

[0038] like Figure 1 As shown, the stirring assembly includes a cylinder 19, which is inverted and fixed to the lower end of the top seat 17, and the output end of the cylinder 19 is fixed with a lifting seat 20, and the lower end of the lifting seat 20 is rotatably connected to three groups of stirring claw assemblies, and the three groups of stirring claw assemblies are transmission-coordinated, and the three groups of stirring claw assemblies stir the medicinal pieces above the three groups of silos 7 respectively.

[0039] The conveyor belt 3 runs intermittently, and stops for a certain period of time after running a certain path, so that the stirring assembly can stir the medicinal materials in the feeding port 4. When the conveyor belt 3 stops, the cylinder 19 (model TN10-30) controls the lifting seat 20 to descend, so that the stirring claw assembly stirs the medicinal materials. After stirring for a certain period of time, the cylinder 19 controls the lifting seat 20 to lift, and the stirring claw assembly is lifted to facilitate the movement of the conveyor belt 3.

[0040] like Figure 6 As shown, the stirring claw assembly includes a gear 21, which is rotatably connected to the lower end of the lifting seat 20, and a shaft 22 is fixedly connected to the lower end of the gear 21, and a stirring roller 23 for stirring the decoction pieces is fixedly connected to the lower end of the shaft 22.

[0041] The gear 1 21 drives the stirring roller 23 to rotate through the shaft 22, and the stirring roller 23 stirs the decoction pieces.

[0042] like Figure 1 and Figure 6 As shown, three sets of gears 1 21 are externally meshed and driven together to be connected with a toothed belt 25, a driving member 28 is fixedly connected to the lifting seat 20, and a gear 2 27 is fixedly connected to the output end of the driving member 28. The gear 27 meshes with the toothed belt 25 for transmission, and a plurality of clamping frames 26 for stabilizing the position of the toothed belt 25 are fixedly connected to the lower end of the lifting seat 20.

[0043] The driving member 28 is a mechanical member that can drive the gear 2 27 to rotate. The driving member 28 drives the gear 2 27 to rotate, so that the gear 2 27 drives the toothed belt 25 to rotate. The toothed belt 25 simultaneously drives the three sets of gears 1 21 to rotate, so that the three sets of stirring claw assemblies run simultaneously. The clamping frame 26 prevents the toothed belt 25 from falling off the lower end of the lifting seat 20.

[0044] like Figure 1 and Figure 6 As shown, a dust collecting assembly 30 is fixedly connected to the upper end of the top seat 17, a suction port 24 is opened on the stirring roller 23, the suction port 24 is connected with the upper end of the gear 1 21 through the inside of the shaft 22, an air pipe 29 is connected between the dust collecting assembly 30 and the suction port 24, the air pipe 29 is rotatably connected with the gear 1 21, the air pipe 29 passes through the lifting seat 20, one end is rotatably connected with the gear 1 21, and the other end is connected to the dust collecting port of the dust collecting assembly 30.

[0045] When the stirring roller 23 rotates, the dust suction component 30 absorbs dust or small particles through the air pipe 29 and the suction port 24, and absorbs smaller substances inside the medicinal slices, which not only increases the cleanliness inside the medicinal slices, but also prevents the medicinal slices from being stirred to generate dust and smoke.

[0046] The working principle of the Chinese medicinal material sorting equipment provided by the present invention is as follows:

[0047] The feeding port 4 inside the conveyor belt 3 is driven by the driving roller 2 to move on the upper end of the receiving seat 6, and the medicinal slices are added to the feeding port 4 at one end of the receiving seat 6 by the feeding mechanism 18. The conveyor belt 3 runs, and the partition plate 5 and the feeding port 4 push the medicinal slices to move on the upper end of the receiving seat 6. Whenever the conveyor belt 3 runs a certain path and stops for a certain time, when the conveyor belt 3 stops, the cylinder 19 controls the lifting seat 20 to descend, so that the stirring claw assembly stirs the medicinal slices. After stirring for a certain time, the cylinder 19 controls the lifting seat 20 to lift. The conveyor belt 3 continues to move, and the medicinal pieces in each group of feed ports 4 pass through the fine filter plate 8, the medium filter plate 9 and the large filter plate 10 in turn. The impurities inside the medicinal pieces are filtered out by the fine filter plate 8, the smaller medicinal pieces are filtered out by the medium filter plate 9, and the larger medicinal pieces pass through the large filter plate 10, thereby sorting the impurities, small-sized medicinal pieces and large-sized medicinal pieces into three groups of silos 7. This equipment removes impurities and selects them in grades without tossing the medicinal pieces, with fewer factors to consider. Combined with the stirring component, the sorting efficiency is high and the effect is good.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
