Description

Technical Field

[0001] The utility model relates to the technical field of gastrodia elata screening, in particular to a gastrodia elata screening device. Background Art

[0002] Gastrodia elata, the Chinese medicine name, is the dried tuber of the orchid plant Gastrodia elata. It has the effects of calming wind and relieving convulsions, calming liver yang, dispelling wind and unblocking meridians. It is mainly used to treat internal liver wind, epilepsy, convulsions, dizziness, headache, limb numbness, limb paralysis, rheumatism and pain, etc. As a traditional Chinese medicine with unique medicinal value, its quality and purity are of self-evident importance to the pharmaceutical and health care products industries.

[0003] However, in the past, the screening process of Gastrodia elata mainly relied on manual operation, which was inefficient and difficult to ensure the consistency and accuracy of screening, which undoubtedly affected the overall quality of Gastrodia elata. With the rapid development of science and technology, Gastrodia elata screening devices began to integrate mechanization, automation and intelligent technologies, which significantly improved the screening efficiency and quality. Despite this, traditional screening devices generally adopt a single-layer screening design, which limits the further screening of Gastrodia elata, resulting in low screening efficiency and affected screening quality.

[0004] Chinese patent document CN219540903U discloses a gastrodia elata screening device, comprising a fixed plate, a support leg fixedly mounted on the bottom of the fixed plate, a column fixedly mounted on the top of the fixed plate, and a screening assembly arranged at the top of the fixed plate, wherein the screening assembly comprises an extrusion mechanism mounted at the top of the fixed plate, a screening mechanism is mounted on the inner wall of the column, the screening mechanism is located at the top of the extrusion mechanism, a power mechanism is mounted at the top of the fixed plate, and the power mechanism is located at the right side of the extrusion mechanism; however, the following defects still exist during implementation:

[0005] Although the device in the above document solves the problem that the existing device is turned on by the third motor, the toggle device is driven to rotate under the action of the rotating rod, and the Gastrodia elata is toggled by the toggle device, since the rotation direction of the rotating rod remains unchanged, the toggle device will cause the Gastrodia elata to shift to one side, thereby reducing the screening efficiency. However, the device in the above document still adopts a single-layer screening design during use, which limits the further screening of the Gastrodia elata, resulting in low screening efficiency and affected screening quality. Utility Model Content

[0006] The utility model aims to provide a gastrodia elata screening device to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A gastrodia elata screening device comprises a shell one; a feed funnel is fixedly connected to the upper end of the shell one, a multi-layer screening structure is arranged in the inner cavity of the shell one, the multi-layer screening structure comprises two electric push rods, the lower ends of the two electric push rods are fixedly connected to the bottom wall of the inner cavity of the shell one, the output ends of the two electric push rods are fixedly connected to rubber rods, the lower parts of the outer surfaces of the two rubber rods are commonly fixedly connected to a screening plate one, the screening plate one is rotatably connected to the inner cavity of the shell one, the middle parts of the outer surfaces of the two rubber rods are fixedly connected to a screening plate two, the screening plate two is rotatably connected to the inner cavity of the shell one, the upper parts of the outer surfaces of the two rubber rods are commonly fixedly connected to a screening plate three, the screening plate three is rotatably connected to the inner cavity of the shell one, a plurality of baffle structures are fixedly connected to one side of the shell one, a plurality of baffle structures are fixedly connected to one side of the baffle structure, a plurality of baffle structures are slidably connected to one side of the shell one, and a plurality of collecting structures are fixedly connected to one side of the shell one to which the baffle structures are fixedly connected.

[0009] A further improvement of the technical solution of the utility model is that: a feed port is provided at the upper end of the shell and extends through the upper end of the shell to the lower part, and a plurality of slide grooves are provided on the side wall of the inner cavity of the shell.

[0010] The above-mentioned technical scheme is adopted, in which a feed port is opened at the upper end of the outer shell, so that the staff can transport the Gastrodia elata that needs to be screened from the inner cavity of the feed funnel to the inner cavity of the outer shell, and a slide groove is opened to limit its position when the baffle structure moves up and down, thereby preventing the baffle structure from getting off the track during the movement.

[0011] A further improvement of the technical solution of the utility model is that the baffle structure includes a shell 2, which is fixedly connected to the shell 1, a slide groove 2 is provided on the side of the shell 2 away from the shell 1, a slide groove 3 is provided at the lower part of the shell 2, and a plurality of elastic column structures are fixedly connected to the inner cavity of the slide groove 3.

[0012] The above-mentioned technical scheme is adopted, in which a slide groove three is opened at the lower part of the shell two, so that the slide groove three can be used to limit the position of the baffle structure moving up and down. At the same time, through the cooperation of several slide grooves three, the position of the baffle structure can be limited when the device is screening the Gastrodia elata, to prevent the baffle structure from sliding up and down due to external force, thereby causing the Gastrodia elata in the inner cavity of the shell one to roll out of the inner cavity of the shell one, affecting the screening quality of the device.

[0013] A further improvement of the technical solution of the utility model is that a plurality of sieve holes 2 are opened in the middle of the sieve plate 3, a plurality of sieve holes 1 are opened in the middle of the sieve plate 2, and the diameters of the plurality of sieve holes 2 are greater than the diameters of the plurality of sieve holes 1.

[0014] The above technical solution is adopted. In this solution, since the diameters of several sieve holes 2 are larger than the diameters of several sieve holes 1, sieve holes 2 can first screen out larger particles of Gastrodia elata, and sieve holes 1 can further screen out smaller particles of Gastrodia elata. Through such layered screening, not only the screening efficiency is improved, but also it can ensure that Gastrodia elata is accurately classified according to different sizes. In addition, this design also helps to reduce blockage during the screening process. Since the diameters of sieve holes 2 and sieve holes 1 are different, larger particles of Gastrodia elata are not easy to block the smaller sieve holes 1, thereby ensuring the smooth progress of the screening process.

[0015] A further improvement of the technical solution of the utility model is that the elastic column structure includes a shell three, the inner cavity of the shell three is slidably connected with a sliding column, one end of the sliding column close to the upper wall of the inner cavity of the shell three is fixedly connected with a spring, and the spring is fixedly connected to the upper wall of the inner cavity of the shell three.

[0016] The above-mentioned technical solution is adopted, in which the elastic force of the spring is used to push the sliding column to slide in the three inner cavities of the outer shell, thereby pushing the sliding column to limit the position of the baffle structure, preventing the baffle structure from sliding in the three inner cavities of the slide groove when the device is screening Gastrodia elata, thereby affecting the screening efficiency of the device.

[0017] A further improvement of the technical solution of the utility model is that the baffle structure includes a main board, a slider is fixedly connected to the upper part of the main board, the outer surface of the slider at the same horizontal height is slidably connected to the inner cavity of the slide groove, a plurality of slide rods are fixedly connected to the lower end of the main board, the outer surfaces of the plurality of slide rods are slidably connected to a connecting plate, and the connecting plate is fixedly connected to the outer shell.

[0018] The above-mentioned technical scheme is adopted, in which the discharge port of the outer shell one can be blocked by the cooperation between the main board and the slide groove three, to prevent the Gastrodia elata from rolling out of the inner cavity of the outer shell one from the discharge port of the outer shell one when the Gastrodia elata is screened in the inner cavity of the outer shell one, thereby affecting the screening effect of the device, and the cooperation between the slider and the slide groove one can prevent the baffle structure from detaching from the device, and the cooperation between the slide rod and the connecting plate can further limit the position of the main board.

[0019] A further improvement of the technical solution of the utility model is that the collecting structure comprises a placing rack 1 and a placing rack 2, the placing rack 1 and the placing rack 2 are fixedly connected to the outer shell 1, the inner cavity of the placing rack 2 is slidably connected with a storage box, and the outer surface of the storage box is slidably connected to the inner cavity of the placing rack 1.

[0020] The above technical solution is adopted. In this solution, the storage box is used to collect the Gastrodia elata after screening through the cooperation between the storage box and the discharge port of the shell one, and the storage box can be supported by the cooperation between the placement rack one and the placement rack two.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

The layered screening design not only improves the screening efficiency, but also ensures that the gastrodia elata is accurately classified according to different sizes. In addition, this design also helps to reduce blockages during the screening process, thereby improving the practicability and universality of the device.

[0023] 2.

[0048] like Figure 1-8As shown, when it is necessary to screen the Gastrodia elata, first pour the Gastrodia elata to be screened from the inner cavity of the feed funnel 2 into the inner cavity of the feed port 11, and then the Gastrodia elata will fall into the inner cavity of the shell 1, the upper end of the screening plate 3 35, and then the electric push rod 31 is operated, and the output end of the electric push rod 31 is used to drive the rubber rod 32 to move up and down, so that the rubber rod 32 can be used to drive the screening plate 1 33, the screening plate 2 34 and the screening plate 35 to swing up and down, so that the Gastrodia elata transported to the upper end of the screening plate 3 35, the upper end of the screening plate 2 34 and the upper end of the screening plate 1 33 can be driven to roll, so that part of the Gastrodia elata that falls on the upper end of the screening plate 3 35 will be The volume of the gastrodia elata itself is smaller than the diameter of the second sieve hole 351, and then it falls from the inner cavity of the second sieve hole 351 into the upper end of the first sieve hole 341. Then, part of the gastrodia elata will fall from the inner cavity of the first sieve hole 341 into the upper end of the screening plate 33 because its volume is smaller than the diameter of the first sieve hole 341, thereby completing the multi-layer screening of the gastrodia elata. During the screening, the elastic force of the spring 443 pushes the sliding column 442 to slide in the inner cavity of the shell 3 441, so that the position of the baffle structure 6 is limited by the sliding column 442 to prevent the baffle structure 6 from sliding up and down under the influence of external force during the screening process, so that the discharge port of the shell 1 cannot be closed, which affects the screening quality.

After the collection is completed in storage box 73, the staff can slide and pull out storage box 73 from the inner cavity of placement rack 1 71 and the inner cavity of placement rack 2 72, and then process the Gastrodia elata in the inner cavity of storage box 73.
