Description
Technical Field
[0001] This utility model belongs to the field of screening device technology, specifically a rapid screening device for Bletilla striata root powder. Background Technology
[0002] Bletilla striata root powder is a waste product after harvesting the Chinese medicinal herb Bletilla striata. However, the rootlets and tubers of Bletilla striata are rich in chemical substances with similar or identical structures. Some active ingredients, such as polyphenols and polysaccharides, are present in much higher amounts in the rootlets than in the tubers. Some bifenthrin-like components are even found only in the rootlets, exhibiting superior antibacterial, antimicrobial, and antitumor pharmacological effects compared to the tubers. Furthermore, the antibacterial activity of the alcohol extract from the rootlets is superior to that of the tubers, and the total phenol content of the rootlets is higher than that of the tubers. Both the crude polysaccharides from the rootlets and tubers have in vitro hemostatic effects. Therefore, the rootlets of Bletilla striata have potential edible and medicinal value.
[0003] During the processing of Bletilla striata root powder, various impurities may be mixed in. To improve the subsequent processing quality and efficiency, a vibrating screen is generally used to screen the impurities in the powder. Existing rapid screening devices for Bletilla striata root powder generally use the vibration generated by a vibrating motor to make the powder move continuously on the screen surface, thereby screening and removing the impurities in the powder. However, because the particles of Bletilla striata root powder are very small, when a large amount of Bletilla striata root powder floods into the screening device in a short period of time, it may exceed the processing capacity of the screen, which can easily lead to accumulation and mutual compression on the screen. Excessive powder may also clog the screen mesh. Once the screen is clogged, the powder cannot pass through the screen smoothly, resulting in the interruption of the screening process. Furthermore, it requires a lot of time and manpower to clean the screen afterward, thus reducing the screening efficiency and effect of Bletilla striata root powder. Therefore, a rapid screening device for Bletilla striata root powder is proposed to solve the problems mentioned in the background technology. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1 to 5 As shown, this utility model provides a rapid sieving device for Bletilla striata root powder, including an outer box 1, a storage bin 2 provided at the top of the inner cavity of the outer box 1, and a quantitative component 3 movably connected inside the outer box 1.
[0022] The quantitative component 3 includes a rotating drum 31, on the surface of which two storage bins 32 are symmetrically arranged, and a guide groove 33 is provided on the inner wall of the middle part of the rotating drum 31.
[0023] The inner wall of the outer casing 1 is provided with a feeding trough 4 that matches the storage bucket 32. The inside of the rotating drum 31 is symmetrically connected with two first inclined blocks 5. The upper and lower ends of the first inclined blocks 5 are fixedly connected with spring pieces 6. The inside of the outer casing 1 is fixedly connected with an electronic telescopic rod 7. The top end of the electronic telescopic rod 7 is fixedly connected with a limit rod 8. The inside of the outer casing 1 is arranged in a ring with several second inclined blocks 9 that cooperate with the first inclined blocks 5. The inside of the outer casing 1 is movably connected with a vibrating screen 10. The four corners of the vibrating screen 10 are fixedly connected with spring rods 11. The side of the outer casing 1 is fixedly connected with a motor 12. The output shaft end of the motor 12 is fixedly connected with a rotating rod 13. The two ends of the rotating rod 13 are fixedly connected with eccentric wheels 14. The top of the outer casing 1 is provided with a feeding funnel 16. The bottom of the inner cavity of the outer casing 1 is movably connected with a storage drawer 17.
[0024] The above scheme involves setting up two storage bins 32, so that one of the storage bins 32 rotates above the feeding trough 4 and feeds the powder through the feeding trough 4. At the same time, the storage bin 2 replenishes the powder into the other storage bin 32. Through the cooperation of the vibrating screen 10 and the eccentric wheel 14, the powder is screened from the impurities inside. By moving the limit rod 8 up and down once, it can drive the rotating drum 31 to rotate clockwise once through the cooperation with the guide trough 33. This allows the rotating drum 31 to drive the powder in the two storage bins 32 to be fed through the feeding trough 4 respectively, thereby achieving the effect of batch feeding and improving the screening effect and efficiency of Bletilla striata root powder.
[0025] like Figure 2 and Figure 4 As shown, the bottom of the inner cavity of the storage bin 2 is sloping. One end of the bottom of the storage bin 2 is provided with a circular groove that matches the storage bucket 32. The guide groove 33 is composed of two arc grooves with an arc of 180 degrees. The two arc grooves face opposite directions and are connected at the top and bottom. A connecting post is provided on the outer wall of the top of the limiting rod 8. The connecting post is movably engaged in the inside of the guide groove 33. The inner wall of the outer box 1 is provided with a sliding groove for circumferentially limiting the limiting rod 8.
[0026] The above solution is adopted: the bottom of the storage bin 2 is sloping. Its function is that if the bottom of the storage bin 2 is flat, the powder will easily accumulate at the bottom of the bin and may form clumps due to mutual compression or moisture. The sloping bottom allows the powder to flow continuously into the circular groove, thereby avoiding the powder from stagnating and accumulating at the bottom of the storage bin 2, and thus maintaining the flowability of the powder.
[0027] like Figures 2 to 5As shown, both ends of the first inclined block 5 are inclined, and the opposite ends of the two first inclined blocks 5 penetrate through the outer wall of the rotating drum 31 and extend to the outside of the rotating drum 31. The first inclined block 5 is elastically connected to the rotating drum 31 through the spring piece 6. The first inclined block 5 near the end of the feeding trough 4 abuts against the second inclined block 9. The spring rod 11 is fixedly connected to the outer box 1. The longer end of the rotating rod 13 abuts against the vibrating screen 10. The outer box 1 has a discharge port 15 on the side away from the storage drawer 17.
[0028] The above solution employs the following design: When the first inclined block 5 abuts against the inclined surface of the second inclined block 9, the second inclined block 9 will press the first inclined block 5 towards the interior of the storage bin 32. This pushes the powder to be fed into the storage bin 32 through the first inclined block 5, preventing the powder from accumulating inside the storage bin 32. When the first inclined block 5 releases from contact with the second inclined block 9, the first inclined block 5 will reset under the elastic force of the spring piece 6 until it abuts against the next second inclined block 9. This process is repeated to perform multiple pushes during the powder feeding process, thereby improving the powder feeding speed and efficiency.
[0029] The working principle and usage process of this utility model are as follows: The operator pours the powder of Bletilla striata rootlets to be screened into the storage bin 2 through the feeding funnel 16. Subsequently, the powder flows through the inclined surface at the bottom of the storage bin 2 and into one of the storage barrels 32 via a circular groove. At this time, the operator activates the electronic telescopic rod 7 and the motor 12, thereby causing the electronic telescopic rod 7 to move the limiting rod 8 upward. This causes the connecting column on the outer wall of the limiting rod 8 to follow the trajectory of the arc groove of the guide groove 33. Since the limiting rod 8 can only move upward in a straight line under the limitation of the sliding groove, after the limiting rod 8 moves upward, it will drive the rotating drum 31 to rotate clockwise 180 degrees through cooperation with the guide groove 33. At ten degrees, as the rotating drum 31 rotates, it drives the powder inside the storage bin 32 and the first inclined block 5 to rotate together. When the rotating drum 31 drives the storage bin 32 containing powder to rotate above the discharge chute 4, the powder inside the storage bin 32 gradually flows into the vibrating screen 10 through the discharge chute 4. At the same time, the rotating drum 31 drives the first inclined block 5 to abut against the inclined surface of the second inclined block 9, thereby squeezing the first inclined block 5 towards the inside of the outer box 1 through the second inclined block 9. While the first inclined block 5 is moving, it pushes the powder inside the storage bin 32, thereby preventing the powder from accumulating inside the storage bin 32, thus preventing blockage when the powder is discharged and improving the powder discharge efficiency.
[0030] When the rotating drum 31 rotates 180 degrees, the storage bin 2 replenishes powder into the other storage bin 32 through the circular groove. At the same time, the connecting column on the limiting rod 8 slides into the other arc groove through the arc groove. When all the powder in the storage bin 32 has been discharged, the electronic telescopic rod 7 drives the limiting rod 8 to move down, which in turn causes the connecting column on the outer wall of the limiting rod 8 to slide along the trajectory of the other arc groove. This causes the rotating drum 31 to continue rotating 180 degrees clockwise, which causes the powder in the other storage bin 32 to flow down through the discharge chute 4. This operation is repeated to achieve the function of quantitative batch feeding.
[0031] When the motor 12 starts, it drives the eccentric wheels 14 at both ends to rotate synchronously through the rotating rod 13. When the longer end of the eccentric wheel 14 comes into contact with the vibrating screen 10, the eccentric wheel 14 will squeeze the vibrating screen 10 upward. When the shorter end of the eccentric wheel 14 comes into contact with the eccentric wheel 14, the vibrating screen 10 will be reset under the elastic force of the spring rod 11, thereby achieving the function of vibrating and screening the powder falling on the vibrating screen 10. The rotated powder falls into the storage drawer 17 through the vibrating screen 10 and is collected through the storage drawer 17. Some larger impurities contained in the powder remain on the vibrating screen 10 and are discharged to the outside through the discharge port 15 through the continuous vibration of the vibrating screen 10, thereby achieving the function of rapid screening of Bletilla striata root powder.
