Description

Technical Field

[0001] This invention relates to the field of Gastrodia elata breeding technology, and more specifically, to a screening device and breeding method for Gastrodia elata breeding. Background Technology

[0002] As a traditional Chinese medicine, Gastrodia elata has multiple effects such as calming wind and stopping spasms, suppressing liver yang, and dispelling wind and unblocking collaterals. The breeding method of Gastrodia elata is mainly through asexual reproduction (such as tuber reproduction), but sexual reproduction also exists.

[0003] In the breeding process of Gastrodia elata, selecting high-quality Gastrodia elata seeds is a crucial step. However, some of the Gastrodia elata seeds currently collected may contain hollow stems. These hollow seeds are difficult to identify from the outside, and their internal structure is damaged, preventing them from developing normally. Existing screening devices also face significant difficulties in removing these hollow seeds, leading to inaccurate screening, affecting the overall survival rate of Gastrodia elata seeds, and causing some economic losses to breeders.

[0004] Therefore, this application proposes a screening device and breeding method for Gastrodia elata breeding to solve the above problems. Summary of the Invention

[0005] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide a screening device and breeding method for Gastrodia elata breeding, which solves the problem that the existing screening device cannot effectively remove some hollow seeds in Gastrodia elata seeds.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a screening device for Gastrodia elata breeding, comprising a base, and further comprising: an inner cylinder installed on the top of the base; an inner ring opening opened in the middle of the inner cylinder; an exhaust assembly installed at the bottom of the inner cylinder for providing annular airflow to the inner ring opening; a funnel plate installed on the top of the inner cylinder, wherein the funnel plate is equipped with an annular outlet, and the annular outlet is vertically aligned with the inner ring opening; and an outer cylinder disposed outside the inner cylinder, wherein the outer cylinder is supported by four mounting columns equidistantly installed on the lower side of its inner wall.

The return flow assembly is vertically set at the top of the inner cylinder with the vertical axis center line of the inner cylinder. The return flow assembly is triggered by the rising airflow discharged from the inner ring opening; a discharge assembly is installed on the inner side of the top of the support ring cover to discharge Gastrodia elata in a ring.

[0007] In a new embodiment, the inner side of the bottom wall of the support ring cover blocks the outer periphery of the top of the outer cylinder.

[0008] In a new embodiment, the exhaust assembly includes: an annular exhaust port installed at the bottom of the inner cylinder; and an air pump installed on the lower part of the outer wall of the inner cylinder, wherein the exhaust port of the air pump is connected to the air inlet of the annular exhaust port through a pipeline.

[0009] In a new embodiment, the buffer assembly includes: an annular airbag installed on the upper part of the inner wall of the outer cylinder; and vertical slide strips installed at equal intervals on the outer side of the annular airbag in vertical slide grooves, which are equidistantly annularly opened on the upper part of the inner wall of the outer cylinder, and the vertical slide strips are slidably connected in the vertical slide grooves.

[0010] In a new embodiment, the recirculation assembly includes: an upper cover plate installed at the bottom center of a four-legged bracket; a lower guide umbrella disposed at the bottom center of the upper cover plate; a frame equidistantly arranged in a ring between the upper cover plate and the lower guide umbrella, and the upper cover plate and the lower guide umbrella are connected by multiple frames; a guide column, one end of which is installed at the bottom center of the upper cover plate, and the other end of which extends to the center of the lower guide umbrella; and an annular air nozzle installed at the bottom of the lower guide umbrella, and the annular air nozzle is connected to the lower guide umbrella.

[0011] In a new embodiment, the discharge assembly includes: a motor, mounted on the outer side of the top of the support ring cover, and a gear fixedly mounted on the output end of the motor; an inner ramp ring, mounted on the inner side of the top of the support ring cover; an outer gear ring, rotatably mounted on the outer side of the top of the inner ramp ring, and meshing with the gear; a discharge box, mounted on the top of the outer gear ring; and a discharge port, opened at the middle of the bottom end of the discharge box, with the discharge port located at the top of the inner ramp ring.

[0012] In a new embodiment, the discharge assembly further includes: two ramp boxes, installed on the left and right sides inside the discharge box; an inner groove, formed in the middle of the inward side of the ramp box, with a rubber blocking block sliding inside the inner groove; a spring post, slidably installed in the middle of the inner groove, with one end of the spring post connected to the outward end of the rubber blocking block, and the other end of the spring post being a magnet end; and a second motor, installed on the bottom wall of the ramp box, with a cross magnetic head fixedly connected to the output end of the second motor.

[0013] In a new embodiment, a lower pipe is fixedly installed at the bottom end of the funnel plate, and multiple flexible wool rings are equidistantly installed on the inner wall of the lower pipe.

[0014] In a new embodiment, a semi-circular material box is provided on both the left and right sides of the bottom of the outer cylinder, and the semi-circular material box is placed at the top of the outer wall protrusion of the inner cylinder. A receiving box is provided at the bottom of the inner cylinder, and the receiving box is placed at the top center of the base.

[0015] A method for breeding Gastrodia elata includes the following steps:

[0016] S1. Gastrodia elata discharge: First, the Gastrodia elata is fed into the discharge assembly, which makes it continuously discharge in a circular motion. The discharged Gastrodia elata then enters the rising airflow released by the inner cylinder and begins to undergo the screening process of hollow Gastrodia elata.

[0017] S2. Screening Gastrodia elata: Continuing from step S1, the Gastrodia elata are further classified in the rising airflow released by the inner tube. Normal Gastrodia elata, due to its own weight, is not affected by the rising airflow and falls downwards. Hollow Gastrodia elata, because it is hollow inside, is lighter in weight and will remain in a suspended state floating up and down in the rising airflow.

[0018] S3. Hollow Removal: The rising airflow discharged from the inner cylinder is returned by the reflux component and converted into a horizontal annular airflow. The annular airflow blows the hollow Gastrodia elata suspended in the rising airflow outward. The blown-out Gastrodia elata will fall into the space between the inner cylinder and the outer cylinder. The buffer component is used to prevent the blown-out hollow Gastrodia elata from colliding with the inner wall of the outer cylinder. Then the hollow Gastrodia elata will fall into the semi-circular material box at the bottom of the outer cylinder for collection.

[0019] S4. Good Product Collection: Normal Gastrodia elata that falls into the funnel plate rolls down and is cleaned and buffered by the lower drain pipe equipped with flexible wool rings, which slows down its falling speed to reduce damage, and finally falls into the receiving box at the bottom of the lower drain pipe for collection.

[0020] Beneficial effects: Compared with the prior art, the advantages of the present invention are: 1. By setting up an inner cylinder, an inner ring mouth, a funnel plate, an annular discharge port and an outer cylinder, the annular rising airflow ejected from the inner ring mouth is used to screen Gastrodia elata, so that the hollow Gastrodia elata is suspended, and the high-quality Gastrodia elata naturally falls into the funnel plate for discharge, which significantly improves the screening efficiency and the breeding quality of Gastrodia elata.

[0021] 2. By setting up an upper cover plate, a lower guide umbrella, a frame, a guide column, and an annular air nozzle, the annular airflow ejected from the inner annular opening passes through the guide space formed by the upper cover plate, the lower guide umbrella, and the frame, and is transformed into a transverse airflow, which is then ejected from the annular air nozzle. This effectively blows out the hollow Gastrodia elata suspended in the annular rising airflow, improving the screening efficiency.

[0022] 3. By setting up an annular airbag, vertical sliding strips, and vertical sliding grooves, the annular airbag effectively reduces the impact of the hollow gastrodia elata blown out by the reflux component on the inner wall of the outer cylinder. Combined with the setting of vertical sliding strips and vertical sliding grooves, the annular airbag can be conveniently fixed and installed, improving maintenance efficiency.

[0023] 4. By setting up a motor, gears, inner inclined ring, outer gear ring, and discharge box, the motor drives the gear to rotate the outer gear ring, realizing the circular motion of the discharge box, which quickly and evenly discharges the gastrodia elata from the discharge box, improving the discharge speed and the utilization rate of the annular upward airflow ejected from the inner ring opening.

[0024] 5. By setting up inclined boxes, inner grooves, rubber blocking blocks, spring columns, motor two, and cross magnetic heads, motor two drives the cross magnetic head to rotate, thereby magnetically attracting and pulling the spring column and rubber blocking blocks, realizing the opening and closing of the space between the two inclined boxes inside the discharge box, controlling the discharge rhythm of Gastrodia elata, and ensuring that Gastrodia elata can adapt to the circular moving discharge box.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] This application provides a screening device and breeding method for Gastrodia elata breeding, which solves the problem that existing screening devices cannot effectively remove some hollow seeds in Gastrodia elata seeds. In use, the annular rising airflow ejected from the inner ring 3 makes the hollow Gastrodia elata suspend and be discharged by the reflux component 11, while the high-quality Gastrodia elata suspends naturally and falls into the funnel plate 5 for discharge, which significantly improves the screening efficiency and the quality of Gastrodia elata breeding.

[0038] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0039] Example 1

[0040] Please see Figures 1-10A screening device for Gastrodia elata breeding includes a base 1, and further includes: an inner cylinder 2 installed on the top of the base 1; an inner ring opening 3 located in the middle of the inner cylinder 2; an exhaust assembly 4 installed at the bottom of the inner cylinder 2 to provide annular airflow to the inner ring opening 3; a funnel plate 5 installed on the top of the inner cylinder 2, with an annular outlet 6 installed on the funnel plate 5, and the annular outlet 6 is vertically aligned with the inner ring opening 3; and an outer cylinder 7 located outside the inner cylinder 2, connected to the outer wall of the inner cylinder 2 by four mounting columns equidistantly installed on the lower side of the inner wall; and supports. A support ring cover 8 is installed at the top of the outer cylinder 7; a buffer assembly 9 is installed on the upper inner wall of the outer cylinder 7 to provide a buffer impact zone for the discharged hollow Gastrodia elata; a four-legged bracket 10 is installed on the outer side of the top of the support ring cover 8, and a return flow assembly 11 is installed at the middle of the bottom end of the four-legged bracket 10. The return flow assembly 11 is vertically set at the top of the inner cylinder 2 with the vertical axis center line of the inner cylinder 2. The return flow assembly 11 is triggered by the rising airflow discharged from the inner ring port 3; a discharge assembly 12 is installed on the inner side of the top of the support ring cover 8 to discharge Gastrodia elata in a ring.

[0041] In this embodiment, please refer to Figures 1-10 As shown, by setting up an inner cylinder 2, an inner ring opening 3, a funnel plate 5, an annular discharge port 6, and an outer cylinder 7, the inner ring opening 3 on the inner cylinder 2 provides an annular constrained upward airflow for the exhaust assembly 4. When Gastrodia elata is discharged into this annular upward airflow through the discharge assembly 12, the non-hollow Gastrodia elata begins to fall due to its weight and is discharged along the slope of the funnel plate 5. The hollow Gastrodia elata, being hollow inside and lighter in weight, will remain in a suspended state floating up and down in the upward airflow. The return assembly 11 returns the upward airflow discharged from the inner cylinder 2 and converts it into a horizontal annular airflow. This airflow blows the hollow Gastrodia elata suspended in the upward airflow outward. The blown-out Gastrodia elata will fall into the space between the inner cylinder 2 and the outer cylinder 7 and be collected later. This is beneficial for screening out higher quality Gastrodia elata for subsequent breeding, and the screening efficiency is also significantly improved.

[0042] Further, please refer to Figure 7 The inner side of the bottom wall of the support ring cover 8 blocks the top periphery of the outer cylinder 7. By using the top blockage of the inner side of the bottom wall of the support ring cover 8, the hollow gastrodia elata blown out by the return component 11 can be prevented from leaving the space between the inner cylinder 2 and the outer cylinder 7, thus achieving a spatial constraint effect on the discharged hollow gastrodia elata.

[0043] Further, please refer to Figure 7A lower drain pipe 13 is fixedly installed at the bottom of the funnel plate 5. Multiple flexible hair rings 14 are installed at equal intervals on the inner wall of the lower drain pipe 13. By setting up the funnel plate 5, the lower drain pipe 13 and the flexible hair rings 14, the funnel plate 5 is used to receive the falling high-quality Gastrodia elata and gather and discharge the material. The lower drain pipe 13 connected to the bottom of the funnel plate 5 discharges the material downwards. The flexible hair rings 14 in the lower drain pipe 13 can clean the Gastrodia elata to a certain extent and also allow the Gastrodia elata to fall downwards more slowly and continuously, thus completing the collection of high-quality Gastrodia elata for breeding.

[0044] Further, please refer to Figure 7 The bottom left and right sides of the outer cylinder 7 are provided with semi-circular material boxes 15, and the semi-circular material boxes 15 are placed on the top of the outer wall protrusion of the inner cylinder 2. The bottom of the inner cylinder 2 is provided with a receiving box 16, which is placed at the top center of the base 1. By setting the semi-circular material boxes 15 and the receiving box 16, the semi-circular material boxes 15 are used to collect the hollow gastrodia elata that falls between the inner cylinder 2 and the outer cylinder 7. There are two semi-circular material boxes 15, which can be closed and disassembled, making them more convenient to use. The receiving box 16 is used to collect the high-quality breeding gastrodia elata discharged from the lower pipe 13.

[0045] Example 2

[0046] Please see Figures 7-8 The exhaust assembly 4 includes: an annular exhaust port 41, installed at the bottom of the inner cylinder 2; and an air pump 42, installed on the lower part of the outer wall of the inner cylinder 2. The exhaust port of the air pump 42 is connected to the air inlet of the annular exhaust port 41 through a pipeline. By setting the annular exhaust port 41 and the air pump 42, the air pump 42 provides airflow to the annular exhaust port 41. The supplied airflow is constrained by the inner ring 3 on the inner cylinder 2 to form an upward blowing annular airflow, which provides the basic conditions for the screening of hollow Gastrodia elata.

[0047] Further, please refer to Figures 5-6 The buffer assembly 9 includes: an annular airbag 91, installed on the upper part of the inner wall of the outer cylinder 7; vertical slide bars 92, equidistantly installed on the outer side of the annular airbag 91; and vertical slide grooves 93, equidistantly annularly formed on the upper part of the inner wall of the outer cylinder 7, with the vertical slide bars 92 slidably connected within the vertical slide grooves 93. By setting the annular airbag 91, vertical slide bars 92, and vertical slide grooves 93, the annular airbag 91 installed on the upper part of the inner wall of the outer cylinder 7 can effectively buffer the impact of the hollow gastrodia elata discharged through the return assembly 11, preventing it from colliding with the outer wall of the outer cylinder 7. Furthermore, the annular airbag 91 can slide into the vertical slide grooves 93 corresponding to the vertical slide bars 92 through the multiple installed vertical slide bars 92, facilitating quick fixation of the annular airbag 91 and making installation and maintenance more efficient.

[0048] Please see Figures 1-4The recirculation assembly 11 includes: an upper cover plate 111, installed at the bottom center of the four-legged bracket 10; a lower guide umbrella 112, disposed at the bottom center of the upper cover plate 111; a frame 113, equidistantly arranged in a ring between the upper cover plate 111 and the lower guide umbrella 112, and the upper cover plate 111 and the lower guide umbrella 112 are connected by multiple frames 113; a guide column 114, one end of which is installed at the bottom center of the upper cover plate 111, and the other end extends to the center of the lower guide umbrella 112; and an annular nozzle 115, installed at the bottom of the lower guide umbrella 112, and the annular nozzle 115 is connected to the lower guide umbrella 112.

[0049] By setting up an upper cover plate 111, a lower guide umbrella 112, a frame 113, a guide column 114, and an annular air nozzle 115, the annular airflow ejected from the inner annular port 3 of the inner cylinder 2 is received by the return assembly 11. The received airflow enters the hollow space of the inwardly guiding umbrella shape composed of the upper cover plate 111, the lower guide umbrella 112, and the frame 113, and with the downward guidance of the guide column 114, the airflow enters the annular air nozzle 115 at the bottom and is exhausted outward from the annular air nozzle 115, thereby forming a transverse annular airflow. This facilitates the blowing out of the hollow Gastrodia elata suspended in the rising airflow ejected from the inner annular port 3 of the inner cylinder 2, thereby improving the screening efficiency of hollow Gastrodia elata and high-quality Gastrodia elata.

[0050] Example 3

[0051] Please see Figure 9 The discharge assembly 12 includes: a motor 121, which is installed on the outer side of the top of the support ring cover 8, and a gear 122 is fixedly installed on the output end of the motor 121; an inner ramp ring 123, which is installed on the inner side of the top of the support ring cover 8; an outer gear ring 124, which is rotatably installed on the outer side of the top of the inner ramp ring 123, and the outer gear ring 124 meshes with the gear 122; a discharge box 125, which is installed on the top of the outer gear ring 124; and a discharge port 126, which is opened in the middle of the bottom end of the discharge box 125, and the discharge port 126 is located on the top of the inner ramp ring 123.

[0052] By setting up a motor 121, a gear 122, an inner inclined ring 123, an outer gear ring 124, a discharge box 125, and a discharge port 126, the motor 121 drives the gear 122 to rotate, and the gear 122 then drives the meshing outer gear ring 124 to rotate on the inner inclined ring 123, thereby driving the discharge box 125 installed on the outer gear ring 124 to perform a circular motion, thus performing a circular discharge of Gastrodia elata, improving the discharge speed of Gastrodia elata and improving the screening efficiency of hollow Gastrodia elata. The Gastrodia elata discharged through the discharge box 125 and the discharge port 126 rolls down the slope of the inner inclined ring 123 into the upward airflow sprayed from the inner ring port 3 of the built-in cylinder 2 for subsequent screening operations.

[0053] Further, please refer to Figure 10The discharge assembly 12 also includes: two ramp boxes 127, installed on the left and right sides inside the discharge box 125; an inner groove 128, opened in the middle of the inward side of the ramp box 127, and a rubber blocking block 129 sliding in the inner groove 128; a spring post 1210, slidably installed in the middle of the inner groove 128, and one end of the spring post 1210 is connected to the outward end of the rubber blocking block 129, and the other end of the spring post 1210 is a magnet end; and a second motor 1211, installed on the bottom wall of the ramp box 127, and a cross magnetic head 1212 is fixedly connected to the output end of the second motor 1211.

[0054] By setting up ramp boxes 127, inner grooves 128, rubber blocking blocks 129, spring pillars 1210, motor 1211, and cross magnets 1212, the two ramp boxes 127 installed inside the discharge box 125 first allow the gastrodia elata in the discharge box 125 to be discharged through the gap between the two ramp boxes 127. During the discharge stage, the motor 1211 drives the cross magnets 1212 to rotate, and the cross magnets 1212 then magnetically attract and pull the magnet end of the spring pillar 1210 sliding on the inner groove 128 (the cross magnets 1212 are equipped with four positive magnets, and the spring pillar...). The magnet end of 1210 is a negative magnet, which causes the rubber blocking block 129 connected to the spring column 1210 to enter the inner groove 128, thereby causing the rubber blocking blocks 129 on both sides to separate (as the cross magnetic head 1212 rotates, the two rubber blocking blocks 129 are in a closed and open cycle state, so that the gastrodia can adapt to the subsequent circular movement of the discharge box 125 for discharge). The gastrodia then falls and is finally discharged from the discharge port 126, and is discharged along the circular movement state of the discharge box 125, which fully improves the utilization rate of the upward circular airflow ejected from the inner ring port 3 on the inner cylinder 2.

[0055] Example 4

[0056] Please see Figures 1-10 This embodiment also provides a method for breeding Gastrodia elata, including the following steps:

[0057] S1. Gastrodia elata discharge: First, the Gastrodia elata is fed into the discharge assembly 12, which makes it continuously discharge in a circular motion. The discharged Gastrodia elata then enters the rising airflow released by the inner cylinder 2 and begins to undergo the screening process of hollow Gastrodia elata.

[0058] S2. Screening Gastrodia elata: Continuing from step S1, the Gastrodia elata are further classified in the rising airflow released by the inner tube 2. Normal Gastrodia elata, due to its own weight, is not affected by the rising airflow and falls downwards. Hollow Gastrodia elata, because it is hollow inside, is lighter in weight and will remain in a suspended state of floating up and down in the rising airflow.

[0059] S3, Hollow Removal: The rising airflow discharged from the inner cylinder 2 is returned by the return component 11 and converted into a horizontal annular airflow. The annular airflow blows the hollow Gastrodia elata suspended in the rising airflow outward. The blown-out Gastrodia elata will fall into the space between the inner cylinder 2 and the outer cylinder 7. The buffer component 9 is used to prevent the blown-out hollow Gastrodia elata from colliding with the inner wall of the outer cylinder 7. Then the hollow Gastrodia elata will fall into the semi-circular material box 15 at the bottom of the outer cylinder 7 for collection.

[0060] S4. Good Product Collection: The fallen normal Gastrodia elata rolls into the funnel plate 5 and is cleaned and buffered by the lower drain pipe 13 equipped with flexible wool ring 14, which slows down its falling speed to reduce damage, and finally falls into the receiving box 16 at the bottom of the lower drain pipe 13 for collection.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.

The bottom of the inner cylinder (2) is provided with a receiving box (16), and the receiving box (16) is placed at the top center of the base (1).

10. A method for breeding Gastrodia elata, characterized in that, The sieving device for Gastrodia elata breeding according to any one of claims 1-9 includes the following steps: S1, Gastrodia elata discharge: First, the Gastrodia elata is fed into the discharge assembly (12) to make it continuously discharge in a circular motion. The discharged Gastrodia elata then enters the rising airflow released by the inner cylinder (2) and begins to undergo the screening process of hollow Gastrodia elata. S2. Screening Gastrodia elata: Continuing from step S1, Gastrodia elata is further classified in the rising airflow released by the inner tube (2). Normal Gastrodia elata, due to its own weight, is not affected by the rising airflow and falls downwards. Hollow Gastrodia elata, due to its hollow interior, is lighter in weight and will remain in a suspended state floating up and down in the rising airflow. S3, Hollow Removal: The rising airflow discharged from the inner cylinder (2) is returned by the reflux component (11) and converted into a horizontal annular airflow. The annular airflow blows the hollow Gastrodia elata suspended in the rising airflow outward. The blown-out Gastrodia elata will fall into the space between the inner cylinder (2) and the outer cylinder (7). The buffer component (9) is used to prevent the blown-out hollow Gastrodia elata from colliding with the inner wall of the outer cylinder (7). Subsequently, the hollow Gastrodia elata will fall into the semi-circular material box (15) at the bottom of the outer cylinder (7) for collection. S4. Good product collection: The fallen normal Gastrodia elata rolls into the funnel plate (5) and is cleaned and buffered by the lower pipe (13) equipped with flexible wool ring (14), which slows down its falling speed to reduce damage, and finally falls into the receiving box (16) at the bottom of the lower pipe (13) for collection.
