Description

Technical Field

[0001] This invention relates to the technical field of pretreatment apparatus for processing medicinal materials using energy-saving electric motors, specifically to a pretreatment apparatus for processing medicinal materials using energy-saving electric motors. Background Technology

[0002] The preparation method of Ginkgo biloba leaf extract includes the following steps: Ginkgo biloba leaf pretreatment, extraction, extract pretreatment, purification, drying, and packaging. During the pretreatment of Ginkgo biloba leaves, washing, drying, and pulverizing are required. Traditional Ginkgo biloba leaf processing involves adding the leaves to different devices for different treatments in separate steps. At each stage, the leaves need to be removed and reinserted into the device required for the next step. This intermediate transfer process is time-consuming and labor-intensive, significantly delaying the overall pretreatment time and reducing work efficiency.

[0003] Patent publication number CN215843384U relates to the technical field of a pretreatment device for medicinal material processing using an energy-saving electric motor. It includes a base, a drying chamber fixedly connected to the upper surface of the base, a partition fixedly connected to the upper surface of the drying chamber, a washing chamber fixedly connected to the upper surface of the partition, a cover plate snapped onto the upper surface of the washing chamber, and a cabinet door hinged to the front of the drying chamber. This pretreatment device for medicinal material processing using an energy-saving electric motor, through the arrangement of the drying chamber, partition, washing chamber, stirring rod, cutting blade, heating rod, through hole, and air inlet pipe, enables the device to simultaneously perform washing, drying, and pulverizing of ginkgo leaves. This eliminates the need to repeatedly remove and change equipment, saving time and labor, significantly reducing the time required for transportation, thereby effectively shortening the pretreatment time for ginkgo leaves, improving work efficiency, and facilitating further processing.

[0004] The aforementioned patent saves time and effort, significantly reducing the time required for transportation and thus effectively shortening the time needed for pre-treatment of ginkgo leaves, improving work efficiency, and facilitating further processing. However, during the grinding of ginkgo leaves, the edges of the leaves may be squeezed, affecting the grinding effect. When feeding the ginkgo leaves into the abrasive frame, too many leaves may enter at once, causing them to submerge the grinding cylinder, affecting the grinding effect and reducing work efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a pretreatment device for processing medicinal materials that uses an energy-saving electric motor, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a pretreatment device for processing medicinal materials using an energy-saving electric motor, comprising a storage tank, a support frame fixedly installed at the bottom of the storage tank, a storage box provided at the bottom of the storage tank, a feeding trough fixedly installed at the top of the storage tank, a rotating shaft fixedly installed at the top of the inner wall of the storage tank, a scraper fixedly installed on the circumferential surface of the rotating shaft, an abrasive frame fixedly installed on the inner wall of the storage tank, a grinding cylinder fixedly installed on the circumferential surface of the rotating shaft, a screen fixedly installed on the inner wall of the storage tank, and a feeding device also provided on the inner wall of the storage tank; The feeding device includes a push rod, a vertical rod, a hinged plate, an L-shaped rod, a first square plate, an inclined rod, a pressure rod, and a second square plate. The feeding trough is connected to the storage tank. The push rod is fixedly installed on the circumferential surface of the rotating shaft. The hinged plate is rotatably installed at the bottom of the feeding trough. The vertical rod is fixedly installed at the bottom of the hinged plate. The first square plate is rotatably installed on the inner wall of the feeding trough. The second square plate is rotatably installed on the side of the first square plate away from the hinged plate. One end of the L-shaped rod is fixedly installed on the top of the hinged plate, and the other end is fixedly installed on a... The first square plate is located near the opening and closing plate. The diagonal rod is fixedly installed on the top of the second square plate, and the pressure rod is fixedly installed on the end of the diagonal rod away from the second square plate. When the L-shaped rod rotates, it pulls the first square plate to rotate, which pushes the ginkgo leaves stored in the feeding trough into the storage tank, accelerating the sliding speed of the ginkgo leaves into the storage tank and improving work efficiency. The movement of the diagonal rod pulls the pressure rod to move closer to the first square plate, and the movement of the pressure rod clears the inside of the feeding trough, accelerating the downward movement of the ginkgo leaves and clearing blockages in the feeding trough.

[0007] According to the above technical solution, the push rod and the vertical rod are provided with an inclined surface on the side that are close to each other. The inclined surface is provided to facilitate the push rod to push the vertical rod to move. A first torsion spring is provided between the opening and closing plate and the feeding trough. The first torsion spring is provided to facilitate the opening and closing plate to return to its original position. A second torsion spring is provided between the first square plate and the feeding trough. The second torsion spring is provided to facilitate the first square plate to return to its original position. A third torsion spring is provided between the second square plate and the first square plate. The third torsion spring is provided to facilitate the second square plate to return to its original position.

[0008] According to the above technical solution, the inner wall of the storage tank is also equipped with a grinding device and a collecting device. The grinding device includes a first connecting rod, a pressure plate, a ring, a second connecting rod, and an arc plate. The pressure plate is slidably installed on the inner wall of the storage tank. One end of the first connecting rod is rotatably installed at the bottom of the vertical rod, and the other end of the first connecting rod is rotatably installed at the top of the pressure plate. The ring is slidably installed on the inner wall of the abrasive frame. The arc plate is slidably installed at the bottom of the inner wall of the abrasive frame. One end of the second connecting rod is rotatably installed at the bottom of the ring, and the other end of the second connecting rod is rotatably installed at the top of the arc plate. The downward sliding of the ring will push the second connecting rod to move. The movement of the second connecting rod will push the arc plate to slide in the direction of the rotating axis. The sliding of the arc plate will push the ginkgo leaves to move towards the center position, thereby improving the grinding efficiency of the ginkgo leaves and preventing the ginkgo leaves from being scattered on both sides of the abrasive frame, thus avoiding insufficient grinding of the ginkgo leaves.

[0009] According to the above technical solution, the grinding device further includes a long rod, a pusher block, a rotating plate, and a soft scraper. The long rod is slidably installed at the bottom of the inner wall of the grinding frame, and a discharge port is opened at the bottom of the inner wall of the grinding frame. The rotating plate is rotatably installed on the inner wall of the discharge port, the pusher block is fixedly installed on the top of the rotating plate, and the soft scraper is fixedly installed on the circumferential surface of the rotating shaft. By collecting and discharging the ginkgo leaf powder at once, the efficiency of the ginkgo leaf powder can be improved. After grinding, the powder is first centrally processed, which can reduce the situation where the powder is dispersed in various areas and facilitate a uniform screening operation of the entire powder. This can improve the efficiency of the screening process and ensure that the screening is more uniform and faster.

[0010] According to the above technical solution, a No. 1 spring is provided between the ring and the abrasive frame. The No. 1 spring is provided to drive the ring back to its original position. A No. 4 torsion spring is provided between the rotating plate and the discharge port. The No. 4 torsion spring is provided to drive the rotating plate back to its original position. A No. 2 spring is provided between the arc plate and the abrasive frame. The No. 2 spring is provided to facilitate pulling the arc plate back to its original position. A No. 3 spring is provided between the pressure plate and the storage tank. The No. 3 spring is provided to facilitate pushing the pressure plate back to its original position.

[0011] According to the above technical solution, the collecting device includes a third connecting rod, a sliding rod, a rotating rod, a sliding pressure plate, a first protrusion, a second protrusion, a rotating plate, and a scraper. The sliding rod is slidably installed at the bottom of the abrasive frame. One end of the third connecting rod is rotatably installed at the bottom of the rotating plate, and the other end of the third connecting rod is rotatably installed on the side of the sliding rod near the rotating plate. The sliding pressure plate is slidably installed on the inner wall of the storage tank. One end of the rotating rod is installed on the end of the sliding rod away from the third connecting rod, and the other end of the rotating rod is rotatably installed on the top of the sliding pressure plate. A collecting groove is opened at the top of the screen. The rotating plate is rotatably installed on the inner wall of the collecting groove. The first protrusion is fixedly installed at the bottom of the screen. The second protrusion is fixedly installed on the circumferential surface of the rotating shaft. The scraper is fixedly installed on the circumferential surface of the rotating shaft. When the first protrusion is impacted, the screen vibrates, increasing the speed at which the screen filters the ginkgo leaf powder. By striking and vibrating, the powder can be effectively vibrated, causing it to pass through the screen holes, reducing clogging and improving screening efficiency.

[0012] According to the above technical solution, the collecting device further includes an inclined plate, a fourth connecting rod, a push rod, a limiting rod, a fixing block, a drawer, and a collecting frame. The inclined plate is fixedly installed at the bottom of the screen, the collecting frame is fixedly installed on the outer wall of the storage tank and communicates with the storage tank, the drawer is slidably installed on the inner wall of the collecting frame, the push rod is slidably installed on the top of the inclined plate, one end of the fourth connecting rod is rotatably installed at the bottom of the rotating plate, the other end of the fourth connecting rod is rotatably installed at the end of the push rod near the rotating plate, and the limiting rod is slidably installed... The fixing block is fixedly installed on the top of the drawer box, mounted on the inner wall of the collection frame. When the limiting rod slides down, it inserts into the fixing block, thus limiting the drawer box and preventing it from being removed when the incompletely crushed ginkgo leaves slide into it. This avoids the drawer box being removed when the incompletely crushed ginkgo leaves slide into it, causing the incompletely crushed ginkgo leaves to fall to the ground. The ginkgo leaf powder that falls to the ground will be contaminated with impurities, preventing the incompletely crushed ginkgo leaves from re-entering the feeding trough and resulting in material waste.

[0013] According to the above technical solution, a No. 4 spring is provided between the sliding rod and the abrasive frame to push the sliding rod back to its original position; a No. 5 spring is provided between the sliding pressure plate and the storage tank to push the sliding pressure plate back to its original position; a No. 5 torsion spring is provided between the rotating plate and the collecting groove to facilitate the rotation plate returning to its original position; a No. 6 spring is provided between the limiting rod and the collecting frame to pull the limiting rod back to its original position; and a square groove is provided on the top of the fixing block, the shape of which matches the limiting rod.

[0014] This invention provides a pretreatment device for processing medicinal materials using an energy-saving electric motor. It has the following beneficial effects: (1) In this invention, the movement of the vertical rod will push the opening and closing plate to rotate, and the rotating shaft will drive the push rod to push the vertical rod to move intermittently. The vertical rod will push the opening and closing plate to open and close intermittently, so that the ginkgo leaves will slide into the abrasive frame intermittently, avoiding the ginkgo leaves from entering too much at once and submerging the grinding cylinder, which will affect the grinding of the grinding cylinder and reduce the working efficiency. The rotation of the L-shaped rod will pull the No. 1 square plate to rotate, and the No. 1 square plate will push the ginkgo leaves stored in the feed trough into the storage tank, accelerating the speed at which the ginkgo leaves slide into the storage tank and improving the working efficiency. The movement of the inclined rod will pull the pressure rod to move towards the No. 1 square plate. The movement of the pressure rod will clear the inside of the feed trough and accelerate the downward movement of the ginkgo leaves to clear the blockage of the feed trough.

[0015] (2) In this invention, the downward sliding of the ring will push the second connecting rod to move, the movement of the second connecting rod will push the arc plate to slide in the direction of the rotating shaft, the sliding of the arc plate will push the ginkgo leaf to move towards the center position, thereby improving the grinding efficiency of the ginkgo leaf and preventing the ginkgo leaf from being scattered on both sides of the grinding frame, thus avoiding insufficient grinding of the ginkgo leaf and the accumulation of the ground powder on the rotating plate surface. The movement of the push block will push the rotating plate to rotate, and the rotation of the rotating plate will slide the ground ginkgo leaf powder into the screen surface for screening. By collecting the ginkgo leaf powder and discharging it all at once, the efficiency of the ginkgo leaf powder can be improved. After grinding, the powder is first centrally processed, which can reduce the situation of the powder being scattered in various areas and facilitate the uniform screening operation of the entire powder. This can improve the efficiency of the screening process and ensure that the screening is more uniform and faster.

[0016] (3) In this invention, when ginkgo leaf powder falls onto the screen surface, the rotating shaft will drive the scraper to move and push the ginkgo leaf powder on the screen surface to disperse it, and push the incompletely crushed ginkgo leaves to the rotating plate surface for temporary storage. The rotation of the rotating shaft will drive the second protrusion to move, and the movement of the second protrusion will continuously hit the first protrusion. The impact on the first protrusion will cause the screen to vibrate, increasing the speed of the screen screening ginkgo leaf powder. Through the knocking and vibration, the powder can be effectively vibrated, prompting it to pass through the screen holes and reducing the impact on the screen. To reduce clogging and improve screening efficiency, the limiting rod slides down and inserts into the fixing block. This limit rod restricts the removal of the collection box when incompletely crushed ginkgo leaves slide into it, preventing the box from being removed and causing the incompletely crushed ginkgo leaves to fall to the ground. Ginkgo leaf powder on the ground would then collect impurities, preventing the incompletely crushed ginkgo leaves from re-entering the feeding trough and resulting in material waste.

After grinding, the powder is first centrally processed, which can reduce the situation where the powder is dispersed in various areas and facilitate a uniform screening operation of the entire powder. This can improve the efficiency of the screening process and ensure that the screening is more uniform and faster.

[0024] A first spring is provided between the ring 173 and the abrasive frame 7. The first spring is provided to drive the ring 173 back to its original position.

The limiting rod 191 slides down and inserts into the fixing block 192. The limiting rod 191 inserted into the fixing block 192 will limit the drawer box 193, so that the drawer box 193 cannot be taken out when the incompletely crushed ginkgo leaves slide into the drawer box 193. This prevents the drawer box 193 from being taken out when the incompletely crushed ginkgo leaves slide into the drawer box 193, so that the incompletely crushed ginkgo leaves slide to the ground. The ginkgo leaf powder that falls to the ground will be contaminated with impurities, preventing the incompletely crushed ginkgo leaves from entering the feed trough again, resulting in material waste.

[0028] In this embodiment, when the vertical rod 11 moves, it pushes the first connecting rod 171 to move. The movement of the first connecting rod 171 pushes the pressure plate 172 to slide downwards. The downward sliding of the pressure plate 172 pushes the ring 173 to slide downwards. The downward sliding of the ring 173 pushes the second connecting rod 174 to move. The movement of the second connecting rod 174 pushes the arc plate 175 to slide towards the rotating shaft 5. The sliding of the arc plate 175 pushes the ginkgo leaf to move towards the center position, improving the grinding efficiency of the ginkgo leaf. The movement will push the long rod 176 to slide towards the center position. When the long rod 176 slides, it will come into contact with the push block 177. Then the long rod 176 will push the push block 177 to move. The movement of the push block 177 will push the rotating plate 178 to rotate. The rotation of the rotating plate 178 will slide the ground ginkgo leaf powder into the surface of the screen 9 for screening. The rotation of the rotating shaft 5 will drive the soft scraper 179 to move. The movement of the soft scraper 179 will scrape the ginkgo leaves at the bottom of the inner wall of the abrasive frame 7, and the surface ginkgo leaves will adhere to the inner wall of the abrasive frame 7.

[0029] When ginkgo leaf powder falls onto the surface of screen 9, the rotation of shaft 5 drives scraper 195 to move, pushing and breaking up the ginkgo leaf powder on the surface of screen 9. Incompletely crushed ginkgo leaves are pushed to the surface of rotating plate 187 for temporary storage. The rotation of shaft 5 drives the second protrusion 186 to move, which continuously impacts the first protrusion 185. The impact on the first protrusion 185 causes screen 9 to vibrate, increasing the speed of ginkgo leaf powder sieving. When rotating plate 178 rotates, it pushes the third connecting rod 181 to move. The movement of the third connecting rod 181 pushes the sliding rod 182 to slide, which in turn pushes the rotating rod 183 to move. The movement of the rotating rod 183 then pushes the sliding rod... The sliding pressure plate 184 slides downward, which pushes the rotating plate 187 to rotate downward. The rotation of the rotating plate 187 causes the ginkgo leaves that are not completely crushed to slide into the drawer 193. The rotation of the rotating plate 187 pushes the fourth connecting rod 189 to move. The movement of the fourth connecting rod 189 pushes the push rod 190 to slide in the direction of the limit rod 191. The push rod 190 then pushes the limit rod 191 to slide downward. The limit rod 191 slides downward and inserts into the fixing block 192. The insertion of the limit rod 191 into the fixing block 192 limits the drawer 193, preventing the drawer 193 from being removed when the ginkgo leaves that are not completely crushed slide into it.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
