Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0042] Referring to Figure 1 - Figure 11 , a sorting device for gastrodia elata processing, comprising: a screening unit 3, which is set as a basic screening component.

[0043] The screening unit 3 includes: a sieve plate 311, the angle between the sieve plate 311 and the horizontal plane is 25°-35°, a plurality of sieve holes 313 are provided on the upper surface of the sieve plate 311, a chute 315 and a plurality of first jacks 318 are provided on the side surface of the sieve plate 311, the chute 315 communicates with the sieve holes 313, a baffle 314 is provided on the same side of each sieve hole 313, the baffle 314 is placed in the chute 315, one end of the baffle 314 is connected with a moving plate 316, positioning holes 319 are provided through both ends of the moving plate 316, the plurality of first jacks 318 are divided into two groups, and the two groups of first jacks 318 are symmetrically distributed along the longitudinal axis of the sieve plate 311.

[0044] The length of the sieve plate 311 needs to be long enough to ensure that there are enough sieve holes 313 on it, so as to ensure that the materials can be fully screened through the sieve holes 313 and reduce the possibility of mis-screening.

[0045] The screening unit 3 is a basic unit. Other screening components are obtained by directly using or simply modifying the screening unit 3 and are combined together to form a complete screening device. Moreover, each screening component is very close to each other. When damaged or lost, it is easy to maintain or replace, which can also improve the modification space for customers, adapt to the screening requirements in different regions, and has extremely strong flexibility.

[0046] When the angle between the sieve plate 311 and the horizontal plane is 25°, the inclination angle of the sieve plate 311 is small, the pressure on the sieve plate 311 is small, the material requirement is low, the length of the sieve plate 311 is small, and the manufacturing cost is reduced; When the angle between the sieve plate 311 and the horizontal plane is 35°, the inclination angle of the sieve plate 311 is large, the separation of the sieve plate 311 downward along the inclined plane increases, the speed of the material moving downward is accelerated, and the possibility of the material getting stuck on the sieve plate 311 is reduced. The screening efficiency is improved.

[0047] A pressing plate 321, the pressing plate 321 is located below the sieve holes 313, the pressing plate 321 is rotatably connected with a cylinder 325 through a rod 323, the angle between the pressing plate 321 and the sieve plate 311 is 40°-55°, the bottom of the cylinder 325 is connected with a support plate 327, and the upper surface of the support plate 327 is connected with a positioning plate through a spring 324. The positioning plate is arranged parallel to the support plate 327.

[0048] The angle between the pressing plate 321 and the sieve plate 311 is 40°-55°. Taking the connection line between the pressing plate 321 and the sieve plate 311 as the demarcation line, the sieve plate 311 is located above the demarcation line, the pressing plate 321 is located below the demarcation line, and the pressing plate 321 has an inclined downward slope, which is convenient for the materials screened by the sieve plate 311 to roll down from the pressing plate 321.

[0049] The baffle 314 moves along the transverse axis direction of the sieve plate 311 with the movable plate 316. By changing the volume of one end of the baffle 314 extending into the sieve hole 313, the width of the sieve hole 313 is regulated. The first socket 318 is adapted to the positioning hole 319. The first socket 318 is inserted with a first plug rod 317. One end of the first plug rod 317 passes through the positioning hole 319 and is inserted into the first socket 318. The top edges on both sides of the sieve plate 311 are connected with first side plates 312.

[0050] The width requirements for the sieve holes 313 are different in each region. Especially for the purchasers of Gastrodia elata, their requirements for Gastrodia elata are often more diverse. Therefore, it is necessary to quickly adjust the width of the sieve holes 313 according to actual needs. After simply pulling out the first plug rod 317, the movable plate 316 can drive all the baffles 314 at the same time. Each baffle 314 corresponds to a sieve hole 313. By blocking the sieve hole 313 with the baffle 314 and regulating the width of the sieve hole 313, after aligning the positioning hole 319 on the movable plate 316 with the appropriate first socket 318 and fixing it, the adjustment of the width of all sieve holes 313 can be quickly completed, which is convenient and fast.

[0051] The sieve plate 311 and the support plate 327 are integrally formed and form a V-shaped plate. The distance between the centers of adjacent first sockets 318 is 0.1 - 0.5 cm. The width of the sieve hole 313 is 3 - 3.5 cm, and the length of the sieve hole 313 is not more than 12 cm.

[0052] When the distance between the centers of adjacent first sockets 318 is 0.1 cm, the distance between adjacent sockets is small, the unit distance of each movement of the baffle 314 is short, the change in the width of the sieve hole 313 is small, and it can meet the requirements of more sieve hole 313 widths. The adjustment of the width of the sieve hole 313 is more accurate. When the distance between the centers of adjacent first sockets 318 is 0.5 cm, the distance between adjacent sockets is large. After each unit distance movement of the baffle 314, the change in the width of the sieve hole 313 is large, which is convenient for quick adjustment.

[0053] Gastrodia elata is usually divided into multiple grades according to diameter and length (subsequently, the color, moisture content, and quality of Gastrodia elata will also be considered). Usually, it is divided into three or four grades. Now, taking the four grades as an example: First-grade product: The diameter is usually between 2 - 3 cm, and the length is between 7 - 9 cm.

[0054] Second-grade product: The diameter is slightly smaller, usually between 1.5 - 2 cm.

[0055] Third-grade product: The diameter is further reduced, usually between 1.5 - 1 cm.

[0056] Fourth-grade product (or lower grade): The diameter is the smallest, usually less than 1 cm.

[0057] The width and length of the sieve holes 313 need to be able to meet the requirements of different standards. Therefore, the maximum width of the sieve holes 313 is slightly greater than the maximum width of the standard, which is 3 cm, and the longest length of the sieve holes 313 is slightly greater than the longest length of the standard, which is 9 cm, increasing the adjustment space for the width and length of the sieve holes 313.

[0058] The upper screening layer is composed of the screening unit 3.

[0059] The middle screening layer 4 is used to screen the materials after being screened by the upper screening layer. The middle screening layer 4 is arranged directly below the upper screening layer, and the number of the middle screening layers 4 can be any one of 0, one, or more.

[0060] The middle screening layer 4 includes: the screening unit 3. A second jack 41 is opened at the top end of the sieve plate 311, and the second jack 41 is connected with a first arc plate 43 through a first plug plate 42.

[0061] The bottom screening layer 5 is used to screen the materials after being screened by the upper screening layer or the middle screening layer 4. The screening device is composed of the upper screening layer, the middle screening layer 4, and the bottom screening layer 5 arranged at equal intervals in the vertical direction. The bottom screening layer 5 includes: the sieve plate 311. A third jack 51 is opened at the top end of the sieve plate 311, and a second plug plate 52 is inserted into the third jack 51. The top end of the second plug plate 52 is connected with a second arc plate 53. Fourth side plates 54 are connected to the top edges on both sides of the second arc plate 53. One end of the sieve plate 311 away from the arc plate is connected with a fixing plate 55. The fixing plate 55 is integrally formed with the sieve plate 311. The fixing plate 55 is connected with a bottom plate 1. The top of the bottom plate 1 is fixedly connected with the bottom screening layer 5, the middle screening layer 4, and the upper screening layer respectively through connecting plates 2. The distances between adjacent bottom screening layers 5, middle screening layers 4, and upper screening layers are the same.

[0062] The bottom screening layer 5 is the final filtering layer. The relative height of the bottom screening layer 5 is low (compared with the upper screening layer and the middle screening layer 4), and there is no need to buffer the materials. Therefore, there is no need to install buffer devices such as pressing plates 321 and springs 324, greatly saving the manufacturing cost.

[0063] The lengths of the sieve holes 313 on the upper screening layer, the middle screening layer 4, and the bottom screening layer 5 are different, and the lengths of the sieve holes 313 on different levels are determined according to the classification of Gastrodia elata grades.

[0064] When Gastrodia elata is screened into three grades by diameter and length, in order to reduce the cost and space of the screening device, only the upper screening layer and the lower screening layer are needed. The sieve holes 313 of the upper screening layer allow second-class and third-class products to pass through, and the bottom screening layer 5 allows third-class products to pass through. There is no need for the middle screening layer 4. At this time, the number of the middle screening layers 4 is 0.

[0065] When screening Gastrodia elata into four grades by diameter and length, it is impossible to complete the screening of four grades only by the upper layer and the bottom layer 5 of screening. It is necessary to add a middle layer 4 of screening. That is, on the basis of the third grade, for each additional grade, it is necessary to add a middle layer 4 of screening.

[0066] The discharge hopper 61 is arranged on one side of the middle layer 4 of screening. A drawplate 62 is connected to the side of the discharge hopper 61. The drawplate 62 is slidably connected with an insertion box 64. The height of the discharge hopper 61 is adjusted by moving the drawplate 62.

[0067] The pressing plate 321 is made of elastic material. Both sides of one end of the pressing plate 321 are connected to the rod body 323 through reinforcing plates 322. The rod body 323 is rotatably connected with the rotating cylinder. The bottom of the rotating cylinder is connected to the support plate 327 through a support foot 326. Springs 324 are arranged at both sides of the other end of the pressing plate 321. Placing grooves 328 are opened at both sides of the edge of the support plate 327 away from the rotating cylinder. The bottom of the placing groove 328 is connected to the bottom end of the spring 324. Second side plates 329 are connected to the edges of both sides of the support plate 327. The pressing plate 321 is slidably connected with the second side plates 329.

[0068] The pressing plate 321 is made of elastic material, which can reduce the damage caused by the material hitting the pressing plate 321, and at the same time reduce the damage of the pressing plate 321 itself and extend the service life of the pressing plate 321.

[0069] The second jack 41 is inserted into the first plug board 42. The bottom end of the first arc plate 43 is located above the top of the sieve plate 311. Third side plates 44 are connected to the top edges of both sides of the first arc plate 43.

[0070] A plurality of fourth jacks 63 are penetrated and opened on one side of the drawplate 62. A fifth jack 65 is penetrated and opened on the side of the top of the insertion box 64. Both the fourth jack 63 and the fifth jack 65 are composed of two round holes. The second plug rod 66 is inserted into the fourth jack 63. The second plug rod 66 is a U-shaped rod. The distance between adjacent fourth jacks 63 is the same as the distance between the bottom layer 5 of screening and the middle layer 4 of screening.

[0071] By adjusting the height of the discharge hopper 61, the discharge hopper 61 can supply materials to the upper layer of screening or the middle layer 4 of screening and the bottom layer 5 of screening respectively.

[0072] During use, the fixing plate 55 of the bottom layer 5 of screening is fixed on the bottom plate 1. The bottom layer 5 of screening can be clamped with the middle layer 4 of screening or the upper layer. The middle layer 4 of screening can be clamped with the upper layer. According to the actual screening requirements, the number of the middle layer 4 of screening is determined. The upper layer of screening, the middle layer 4 of screening and the bottom layer 5 of screening are respectively connected by threads through the connecting plate 2 to maintain the overall stability.

[0073] When it is necessary to divide gastrodia elata into three grades according to diameter and length, only the upper sieve layer and the middle sieve layer 4 need to be screened. By adjusting the width of the sieve holes 313 on the upper sieve layer and the middle sieve layer 4, after pulling out the first inserting rod 317, the moving plate 316 can drive all the baffle plates 314 at the same time. Each baffle plate 314 corresponds to a sieve hole 313. By blocking the sieve hole 313 with the baffle plate 314 and regulating the width of the sieve hole 313, align the positioning hole 319 on the moving plate 316 with the appropriate first inserting hole 318. For example, the original width of the sieve hole 313 is 3 cm, and the adjusted width of the sieve hole 313 needs to be 2.6 cm. The center distance between adjacent first inserting holes 318 is 0.1 cm. After the positioning hole 319 on the moving plate 316 moves to the adjacent first inserting hole 318 each time, the width of the sieve hole 313 decreases by 0.1 cm. Therefore, the positioning hole 319 on the moving plate 316 needs to be aligned with the fourth first inserting hole 318 (the adjacent first inserting hole 318 is the first one, and they are numbered in sequence).

[0074] After aligning and fixing the positioning hole 319 on the moving plate 316 with the appropriate first inserting hole 318, the adjustment of the width of all the sieve holes 313 can be quickly completed, so that the sieve holes 313 on the upper sieve layer only allow second-grade and third-grade materials (including gastrodia elata) to pass through, and the sieve holes 313 on the bottom sieve layer 5 only allow third-grade materials to pass through.

[0075] Insert the second inserting plate 52 into the third inserting hole 51 so that one end of the second arc plate 53 abuts against the sieve plate 311 of the lower sieve layer. The second arc plate 53 is an arc plate that bends upward, which is equivalent to extending the length and height of the sieve plate 311 to prevent materials from rolling out from the top end of the sieve plate 311.

[0076] Adjust the height of the discharge hopper 61 so that the discharge port of the discharge hopper 61 is directly above the top end of the sieve plate 311 of the upper sieve layer. Pour the material to be screened into the discharge hopper 61. The material falls from the discharge port onto the sieve plate 311 of the upper sieve layer. The first-grade materials have a large diameter and a long length and can only roll onto the collection box from the sieve plate 311. The second-grade and third-grade materials fall through the sieve holes 313, thus separating the first-grade materials from the second-grade and third-grade materials.

[0077] The falling material contacts and impacts the pressing plate 321. The pressing plate 321 is made of elastic material to reduce the impact force between the pressing plate 321 and the material. When the pressing plate 321 is impacted, the pressing plate 321 receives a downward pressure. The pressing plate 321 rotates in the rotating cylinder along with the rod body 323, and the pressing plate 321 squeezes the spring 324. The spring 324 compresses, and the bearing capacity of the pressing plate 321 is increased through the elastic action of the spring 324. The included angle between the pressing plate 321 and the sieve plate 311 is 40° - 55°. Taking the connection line between the pressing plate 321 and the sieve plate 311 as the demarcation line, the sieve plate 311 is located above the demarcation line, and the pressing plate 321 is located below the demarcation line. The pressing plate 321 has a downward slope to facilitate the second-grade or third-grade materials to roll off from the pressing plate 321.

[0078] The sieve holes 313 of the bottom sieve layer 5 only allow materials of the third grade to pass through, thereby separating the materials of the second grade from those of the third grade.

[0079] Before screening, the materials can be observed first to judge the quantity of the materials in different grades and determine which grade of materials is the most. For example, if the materials of the second grade are the most, those of the third grade are the second most, and those of the first grade are the least, the separation of the second grade and the third grade can be completed first. Adjust the height of the discharge hopper 61 so that the discharge port of the discharge hopper 61 is directly above the second arc plate 53 of the bottom sieve layer 5, thereby completing the separation of the materials of the second grade and the third grade. Then, adjust the height of the discharge hopper 61 again so that the discharge port of the discharge hopper 61 is directly above the upper sieve layer, thereby completing the separation of the materials of the first grade and the second grade.

[0080] The discharge hopper 61 is not fixed. By adjusting the height and position of the discharge hopper 61, the position of the discharge port can be changed, and the discharge position can be selected. The adjustment is flexible, which is convenient for screening away the materials of the grade with a large quantity first, reducing the total weight of the materials to be screened by the sieve plate 311 subsequently, reducing the pressure on the sieve plate 311, and improving the screening efficiency.

[0081] When it is necessary to divide gastrodia elata into four or more grades according to the diameter and length, only relying on the upper sieve layer and the bottom sieve layer 5 cannot complete the screening of four grades, and a middle sieve layer 4 needs to be added. That is, on the basis of the third grade, for each additional grade of materials, a middle sieve layer 4 needs to be added. For example, when dividing gastrodia elata into 5 grades according to the diameter and length, two middle sieve layers 4 need to be added. Based on the screening unit 3, by assembling the upper sieve layer, the bottom sieve layer 5 or the middle sieve layer 4, a screening device that meets the screening requirements is constructed, which has strong adaptability and is convenient for installation, disassembly and replacement.

[0083] The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
