Description

Technical Field

[0001] This utility model relates to the technical field of Bletilla striata powder production equipment, and in particular to an integrated device for ultrafine grinding and sieving of Bletilla striata powder. Background Technology

[0002] Bletilla striata powder is made from the processed and pulverized Chinese medicinal herb Bletilla striata. As a traditional Chinese medicinal herb, Bletilla striata is widely used in the medical field. It is rich in a variety of effective ingredients and has the effects of astringing and stopping bleeding, reducing swelling and promoting tissue regeneration. It is often used to treat hemoptysis, hematemesis, traumatic bleeding, sores and carbuncles.

[0003] Traditional ultrafine pulverizing equipment for Bletilla striata powder mainly consists of a pulverizing chamber, pulverizing blades, and a drive motor. In use, the raw material of Bletilla striata is put into the pulverizing chamber, and the drive motor drives the pulverizing blades to rotate at high speed. Through the interaction between the blades and the raw material, Bletilla striata is pulverized into fine particles. However, this traditional equipment has obvious drawbacks. Its function is relatively simple. It can only complete the pulverizing operation and cannot screen the particle size of the pulverized Bletilla striata powder.

[0004] To address the issue that traditional equipment can only crush but not screen, existing technologies have added a screen structure to the crushing equipment. In actual use, the crushed Bletilla striata powder is screened through the screen, and powder of the correct particle size is collected through the screen while larger particles are intercepted, thus controlling the particle size of the Bletilla striata powder. However, in practical applications, since the screen is usually installed in a relatively fixed position inside the equipment, cleaning or replacing the screen often requires the use of special tools, unscrewing multiple screws, and spending a lot of time and effort to disassemble multiple parts of the equipment to remove the screen. This not only reduces the maintenance efficiency of the equipment but may also damage equipment parts due to frequent disassembly. Utility Model Content

[0038] The filtration mechanism 2 includes a sieve plate 201, which is fixedly connected to the middle of the inner wall of the crushing box 1. It is used for preliminary screening of the crushed Bletilla striata powder, separating larger particles that do not meet the particle size requirements. A motor 202 is fixedly connected to the front side of the inner wall of the crushing box 1, providing power for the rotation of the cam 203 to strike the sieve plate 201. The output end of the motor 202 is fixedly connected to the cam 203, which generates a striking force through contact with the sieve plate 201. A second sieve plate 204 is slidably connected to the middle of the inner wall of the crushing box 1, used to filter the Bletilla striata powder after screening by the sieve plate 201. The powder is screened again to further improve the screening accuracy. A sealing plate 205 can be connected to the front end of the second sieve plate 204 to enhance the sealing between the second sieve plate 204 and the crushing box 1 and prevent the Bletilla striata powder from leaking. Two magnets 206 are fixedly connected to the middle of the front side of the outer wall of the crushing box 1. The magnets 206 and the sealing plate 205 attract each other to fix the second sieve plate 204 and facilitate the disassembly and installation of the second sieve plate 204. A handle 207 is fixedly connected to the front side of the outer wall of the sealing plate 205 so that the operator can hold and pull the second sieve plate 204 to clean or replace it.

[0039] Specifically, the feed hopper 5 works in conjunction with the screw conveyor 4 to transport Bletilla striata into the grinding chamber 1, preparing it for subsequent grinding. The grinding assembly 6 performs ultra-fine grinding of Bletilla striata within the grinding chamber 1, which is crucial for achieving fine particle size of the Bletilla striata powder.

A handle 207 allows for easy pulling of the second sieve plate 204. A clearing mechanism 3 is located at the bottom of the inner wall of the grinding chamber 1 for clearing the second sieve plate 204. Support legs 7 are fixed to both sides of the bottom of the grinding chamber 1, providing support. The unloading assembly 8 is located between the two support legs 7 and is used for unloading. These components work together to complete the entire process of Bletilla striata powder from feeding, crushing, screening to unloading.

[0040] Reference Figure 5 , Figure 6 and Figure 7 The unblocking mechanism 3 includes a lead screw 301, which is rotatably connected to the left side of the middle of the inner wall of the crushing box 1. As a transmission component, its function is to convert the rotational motion of the motor 305 into the linear motion of the slide rod 302. The slide rod 302 is threadedly connected to the rear side of the outer wall of the lead screw 301. Through the threaded connection, when the lead screw 301 rotates, it can drive the slide rod 302 to move along the axial direction of the lead screw 301. Guide blocks 304 are fixedly connected to the left and right sides of the outer wall of the slide rod 302 to limit the direction of movement of the slide rod 302 and ensure that the slide rod 302 can only move along a direction parallel to the inner wall of the crushing box 1. Moving in a straight line, the two guide blocks 304 are slidably connected to the left and right sides of the inner wall of the crushing box 1 respectively, ensuring that the guide blocks 304 can slide smoothly on the inner wall of the crushing box 1, thereby ensuring the stable movement of the slide rod 302. Multiple brushes 303 are fixedly connected at equal intervals on the top left and right sides of the slide rod 302. As the slide rod 302 moves, it cleans the screen plate 204 to prevent the screen holes from being blocked. A motor 305 is fixedly connected to the rear side of the outer wall of the crushing box 1 to provide power for the entire unblocking mechanism 3, driving the lead screw 301 to rotate. The output end of the motor 305 is fixedly connected to the lead screw 301.

[0041] Specifically, motor 305 is fixed to the rear side of the outer wall of the crushing chamber 1, and its output end is connected to lead screw 301, providing power to the entire mechanism and driving lead screw 301 to rotate on the left side of the middle of the inner wall of the crushing chamber 1. Lead screw 301 is threadedly connected to slide rod 302, and slide rod 302 moves accordingly when lead screw 301 rotates. Guide blocks 304 on the left and right sides of the outer wall of slide rod 302 are slidably connected to the left and right sides of the inner wall of crushing chamber 1, respectively, to ensure stable linear movement of slide rod 302. Multiple brushes 303, which are equidistantly fixed on the left and right sides of the top of slide rod 302, move with slide rod 302 to unclog the filter holes on sieve plate 204, preventing Bletilla striata powder from clogging the sieve holes, ensuring smooth sieving process, and maintaining efficient operation of the device.

[0042] Reference Figure 3 , Figure 4 and Figure 8The pulverizing component 6 includes a pulverizing cylinder 601, which serves as the main working area for pulverizing Bletilla striata, providing space for the pulverizing process. The outer walls of the pulverizing cylinder 601 are fixedly connected to the inner walls of the pulverizing box 1 on the left and right sides. Multiple screening holes 602 are equidistantly arranged around the outer walls of the pulverizing cylinder 601 to screen Bletilla striata powder that meets the particle size requirements after being pulverized by the pulverizing blade assembly 604, allowing it to exit from the pulverizing cylinder 601. Multiple pulverizing blades 603 are fixedly connected around the inner walls of the pulverizing cylinder 601. The pulverizing blades 603 cooperate with the rotating pulverizing blade assembly 604 to enhance the pulverizing effect and help to pulverize the Bletilla striata raw material more finely. A pulverizing blade assembly 604 is rotatably connected to the inner wall of cylinder 601. Driven by motor 605, it rotates at high speed to perform ultrafine pulverization of the Bletilla striata raw material. Motor 605 is fixedly connected to the right side of the outer wall of pulverizing box 1 to provide power for the rotation of pulverizing blade assembly 604 and ensure smooth pulverization. The output end of motor 605 is fixedly connected to the right end of pulverizing blade assembly 604. A toolbox 15 is fixedly connected to the right side of the outer wall of pulverizing box 1 to store tools required for device maintenance and repair, making it convenient for operators to access at any time. Partitions 16 are fixedly connected to the front and rear sides of the inner wall of toolbox 15 to divide the interior of toolbox 15 into different compartments. The space allows for easy classification and storage of tools, improving tool retrieval efficiency. The unloading assembly 8 includes two fixing blocks 801 for supporting and fixing the chute 802, providing basic support for the sliding plate 803. Each fixing block 801 has a chute 802 on its top, providing a track for the sliding plate 803 and defining its sliding direction. The inner walls of the two chute 802 are slidably connected to the same sliding plate 803, which slides within the chute 802 to receive and transport the crushed and sieved Bletilla striata powder. The top of the sliding plate 803 is slidably connected to the bottom of the crushing box 1, ensuring a tight fit and smooth unloading of the Bletilla striata powder. The top of the slide plate 803 is fixedly connected to a toothed plate 804, which cooperates with a gear 806 to convert the rotational motion of the second motor 805 into the linear motion of the slide plate 803. The second motor 805 is fixedly connected to the left side of the outer wall of the crushing box 1 to provide power to the unloading assembly 8 and drive the gear 806 to rotate. The output end of the second motor 805 is fixedly connected to the gear 806, which rotates under the drive of the second motor 805 and meshes with the toothed plate 804. The gear 806 is meshed with the toothed plate 804. Through this meshing connection, the toothed plate 804 and the slide plate 803 fixed thereto slide in the slide groove 802 to realize the unloading operation of Bletilla striata powder.

[0043] Specifically, the left and right sides of the outer wall of the crushing cylinder 601 are fixedly connected to the left and right sides of the inner wall of the crushing box 1, providing space for crushing operations. Screening holes 602 are equidistantly opened around its outer wall for screening Bletilla striata powder that meets the particle size requirements. Crushing blades 603 are fixed around the inner wall of the crushing cylinder 601, interacting with the rotating crushing blade assembly 604 to enhance the crushing effect. Motor 605 is fixed to the right side of the outer wall of the crushing box 1, with its output end connected to the right end of the crushing blade assembly 604, providing power to the assembly and driving it to rotate within the crushing cylinder 601 for ultra-fine crushing of Bletilla striata. Toolbox 15 is fixed to the right side of the outer wall of the crushing box 1, and its inner wall has partitions 16 on the front and back sides for classifying and storing tools, facilitating device maintenance and repair. Sliding grooves 802 are opened on the top of the two fixed blocks 801, and sliding plates 803 slide within these grooves. The top of the sliding plates 803 is slidably connected to the bottom of the crushing box 1, providing a moving carrier for unloading. The toothed plate 804 fixed to the top of the slide plate 803 meshes with the gear 806 fixed to the output end of the second motor 805. The second motor 805 is fixed to the left side of the outer wall of the crushing box 1. After starting, it drives the gear 806 to rotate, which in turn drives the toothed plate 804 meshing with the gear 806 to move, so that the slide plate 803 slides in the slide groove 802, realizing the unloading of Bletilla striata powder in the crushing box 1. These components work together to ensure the smooth operation of the Bletilla striata powder production process from crushing to unloading.

[0044] Reference Figure 1 , Figure 5 and Figure 9 A cover plate 9 is rotatably connected to the top of the feed hopper 5. It can rotate around the connection point with the top of the feed hopper 5. Its function is to cover the top opening of the feed hopper 5 when no Bletilla striata raw material needs to be added, preventing dust, debris, etc., from entering the feed hopper 5 and contaminating the Bletilla striata raw material. Two latches 10 are fixedly connected to the front side of the outer wall of the feed hopper 5, and two hooks 11 are fixedly connected to the front side of the outer wall of the cover plate 9. The two hooks 11 engage with their corresponding latches 10. The latches 10 cooperate with the hooks 11 to fix the cover plate 9, ensuring that the cover plate 9 remains closed during device operation. In the closed state: A collection box 12 is provided on the left side of the outer wall of the crushing box 1. Two T-shaped blocks 13 are fixedly connected to the right side of the outer wall of the collection box 12, so that it can form a specific connection structure with the crushing box 1, which facilitates the sliding connection between the collection box 12 and the crushing box 1. Both T-shaped blocks 13 are slidably connected to the crushing box 1, which facilitates the installation and removal of the collection box 12. A support frame 14 is fixedly connected to the left side of the outer wall of the crushing box 1 to provide support for the screw conveyor 4 and enhance the stability of the screw conveyor 4 during operation. The top of the support frame 14 is fixedly connected to the bottom of the screw conveyor 4.

[0045] Specifically, the cover plate 9, which is rotatably connected to the top of the feed hopper 5, works in conjunction with the latch 10 on the front side of the outer wall of the feed hopper 5 and the hook 11 on the front side of the outer wall of the cover plate 9. When the hook 11 and the latch 10 are engaged, external impurities can be prevented from entering the feed hopper 5, thus avoiding contamination of the Bletilla striata raw material. At the same time, it can also prevent material spillage during transportation or when not in use. The collection box 12, which is set on the left side of the outer wall of the crushing box 1, is slidably connected to the crushing box 1 through the T-shaped block 13 fixed on the right side of its outer wall. It can collect the Bletilla striata particles that do not meet the particle size requirements after screening, and facilitate centralized processing. The support frame 14 is fixed on the left side of the outer wall of the crushing box 1. Its top is fixedly connected to the bottom of the screw conveyor 4, providing stable support for the screw conveyor 4, ensuring that the screw conveyor 4 remains stable during the conveying of Bletilla striata raw material, avoiding the impact of shaking on the conveying effect, and ensuring the stable operation of the entire device.

[0046] Working Principle: First, Bletilla striata is poured into the feed hopper 5. Then, the screw conveyor 4 is started, moving the Bletilla striata to the right. During this process, the Bletilla striata is initially crushed within the screw conveyor 4 and then sent to the crushing chamber 1. Once the Bletilla striata enters the crushing cylinder 601, the motor 605 activates, driving the crushing blade assembly 604 to rotate at high speed. The crushing blade assembly 604 and the crushing discs 603 work together to crush the Bletilla striata into powder. When the crushed Bletilla striata particles are smaller than the sieve hole 602, they pass through the sieve hole 602 and fall into the crushing chamber 1. The falling Bletilla striata powder is then screened by the sieve plate 201. Simultaneously, the motor 202 rotates, driving the cam 203 to rotate. During the rotation of the cam 203, it strikes the sieve plate 201, accelerating the screening of the Bletilla striata particles. Particles of the correct size fall downwards through sieve plate 201, while particles that do not meet the size requirements roll backwards along the slope of sieve plate 201 and fall into collection box 12 under the vibration of sieve plate 201. The Bletilla striata particles sieved through sieve plate 201 fall onto sieve plate 204, where they are further sieved and enter the bottom of the grinding chamber 1. When sieve plate 204 needs to be removed, the operator simply holds handle 207 and pulls it forward to overcome the magnetic attraction between magnet 206 and sealing plate 205, easily removing sieve plate 204 for cleaning or maintenance. Installation is also simple: insert sieve plate 204 into the middle of the grinding chamber 1, push sealing plate 205 close to magnet 206 so that sealing plate 205 and magnet 206 attract each other, firmly fixing sieve plate 204, allowing for continued ultrafine grinding and sieving of Bletilla striata powder.

[0047] The motor 305 starts, acting as a power source to drive the lead screw 301 to rotate. The lead screw 301 is rotatably connected to the left side of the inner wall of the crushing chamber 1, providing rotational power for the entire unblocking action. Because the slide rod 302 is threadedly connected to the lead screw 301, and the guide blocks 304 on both sides of the slide rod 302 are slidably connected to the left and right sides of the inner wall of the crushing chamber 1, this structural design allows the slide rod 302 to move in a specific direction when the lead screw 301 rotates. The guide blocks 304 serve to restrict and guide movement, ensuring the smooth movement of the slide rod 302. Multiple brushes 303 are equidistantly fixed to the top left and right sides of the slide rod 302, so when the slide rod 302 moves, the brushes 303 also move. The brushes 303 correspond to the screen plate 204, and their function is to unblock the filter holes on the screen plate 204. During the sieving process of Bletilla striata powder, the filter holes of sieve plate 204 are easily clogged by Bletilla striata powder particles, affecting sieving efficiency and quality. At this time, the unblocking mechanism 3, through the above-mentioned working process, periodically or according to the actual situation, starts motor 305 and uses the movement of brush 303 to clean the filter holes, ensuring that sieve plate 204 always maintains a good permeability and ensuring the stable operation of the integrated device for ultrafine grinding and sieving of Bletilla striata powder.
