Description

Technical Field

[0001] This utility model relates to the field of Chinese herbal medicine cultivation, and in particular to a seed screening device for Chinese herbal medicine cultivation. Background Technology

[0002] Herbal medicine is made from plant extracts, primarily utilizing their therapeutic value. Because most plants contain chemical elements, they possess physical therapeutic properties such as healing. Herbal medicine is one of the oldest forms of health maintenance, playing a vital role in ancient times. What was once unheard of in modern medicine is now unthinkable. Primitive humans, utilizing the vast flora and fauna around them, observed plants, animals, and their components to the fullest extent, leading to the birth of herbal medicine. Advances in science and technology have created chemical and new biological drugs. The entire field of pharmacy, from research and production techniques to professional management, has made significant progress. Simultaneously, herbal medicine, which had long been relatively stagnant, has also experienced new development thanks to advancements in science and management. Herbal medicine preparations have gone through three stages of development. The first stage was the traditional pills, powders, ointments, and pastes. The second stage involved combining extraction and coarse processing techniques, primarily using water-alcohol or alcohol-water methods, with modern industrial formulation techniques to produce prepared Chinese medicines. The third stage is the modern stage of refined and quantified herbal medicines using modern separation and detection technologies. Currently, most seed screening devices for Chinese herbal medicine cultivation have simple structures and low screening efficiency. Furthermore, the fine particles such as dust mixed in with the herbs during the screening process can pose a certain health hazard to operators.

[0003] To address the aforementioned problems, a seed screening device has emerged. For example, Chinese Utility Model Patent CN221734044U discloses a seed screening device for planting traditional Chinese medicinal herbs, comprising a screening box, a vibrating sieve assembly, a screening basket, and a vacuum cleaner. The screening box has a protective door at its front end. The vibrating sieve assembly is located on the top of the screening box and extends into the box from the bottom. The screening basket is mounted on the vibrating sieve assembly and located inside the screening box. The vacuum cleaners are symmetrically arranged on both sides of the screening box. The vibrating sieve assembly includes a rotary motor, a rotating shaft, and a lifting frame. A support frame is provided on the top wall of the screening box. The rotary motor is located on one side of the support frame, and the rotating shaft is rotatably mounted within the support frame. The output shaft of the rotary motor is connected to one end of the rotating shaft. Guide grooves are symmetrically provided at both ends of the top wall of the screening box, and the lifting frame slides within the guide grooves. This utility model relates to the technical field of equipment for planting traditional Chinese medicinal herbs, specifically a seed screening device for planting traditional Chinese medicinal herbs with good screening effect and capable of collecting dust particles. However, the sieving and vibrating components of the above-mentioned device drive the lifting frame to move up and down through the eccentric wheel. The vibration amplitude is limited by the size of the eccentric wheel, which may lead to uneven sieving. In particular, the separation effect is not good for small seeds or highly viscous impurities. In addition, the above-mentioned device uses a hand-tightened screw to fix the sieving tube, which requires manual operation. Frequent replacement is inefficient, and the threads are easy to wear and may loosen after long-term use. Therefore, a seed sieving device for Chinese herbal medicine planting is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a seed screening device for planting Chinese herbal medicines.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a seed screening device for planting Chinese herbal medicines, including a screening box with a notch and a hinged door.

The device also includes a multi-stage amplitude adjustment mechanism, which is located on the screening box and has its vibration end connected to multiple vertical rods to drive the vertical rods to swing up and down. The lower ends of the vertical rods extend into the screening box and are magnetically connected to the screening frame via magnetic suction components.

[0007] As a preferred embodiment of this utility model, the multi-stage amplitude adjustment mechanism includes a drive motor, a rotating shaft, a mounting plate, a top plate, a spring, a sliding sleeve, and at least two sets of eccentric block groups. The drive motor is mounted on the upper end of the screening box via a mounting base, and its output shaft is horizontally arranged and coaxially connected to the rotating shaft. The other end of the rotating shaft is rotatably connected to the mounting plate. The eccentric block groups are fixedly sleeved on the rotating shaft. The lower end of the top plate is fixedly connected to multiple vertical rods. Multiple sliding sleeves are fixed on the upper end of the screening box. The vertical rods pass through the corresponding sliding sleeves and are slidably connected to them. The protrusions of the eccentric block groups can lift the top plate upwards. The spring is sleeved on the vertical rod, and one end of it is connected to the magnetic suction element, and the other end is connected to the top wall of the screening box.

[0008] As a preferred technical solution of this utility model, the eccentric block group includes a first eccentric block, a second eccentric block, and a fixing bolt. The first eccentric block has through holes at equal intervals, and the second eccentric block has threaded holes at equal intervals. The fixing bolt passes through the through holes and extends into the threaded holes to be threadedly connected to them.

[0009] As a preferred embodiment of this utility model, the magnetic attracting component includes an electromagnet and a permanent magnet. The screening frame has a groove adapted to the permanent magnet, and the electromagnet is placed in the groove. The permanent magnet is located at the lower end of the vertical rod and is magnetically attracted to the electromagnet.

[0010] As a preferred embodiment of the present invention, the dust collection mechanism includes a vacuum cleaner and an annular dust collection pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention relates to a seed screening device for planting Chinese herbal medicines. Upon opening the box door, an electromagnet is energized. Through magnetic attraction between the permanent magnet and the electromagnet, the screening frame containing the seeds to be processed is attracted to the vertical rod. The drive motor is started, and its output torque is transmitted to the rotating shaft via a coupling. The rotating shaft drives the eccentric block assembly to rotate. The protrusions of the eccentric block assembly lift the top plate upwards. Under the action of a spring, the rotation of the eccentric block assembly causes the top plate and vertical rod to reciprocate up and down. This reciprocating motion of the vertical rod causes the screening frame to sway up and down. Under the action of the filter screen, the seeds in the screening frame can be screened, shaking off unsuitable seeds, mixed dust, and fine particles, which are then discharged from the slag outlet.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Figure 1-2 This utility model provides a seed screening device for planting Chinese herbal medicines, including a screening box 1 with a notch and a door 2 hinged to the notch. A screening frame 6 is located inside the screening box 1 and has an opening at its lower end. A filter screen 3 is installed at the opening. A dust collection mechanism is located on the screening box 1 and its dust collection end extends into the screening box 1. A slag discharge port 4 is located at the lower end of the screening box 1. The device also includes a multi-stage amplitude adjustment mechanism, which is located on the screening box 1 and its vibration end is connected to multiple vertical rods 5 to drive the vertical rods 5 to swing up and down. The lower end of the vertical rods 5 extends into the screening box 1 and is magnetically connected to the screening frame 6 through a magnetic suction component.

[0028] In this embodiment, the door 2 is opened, and the screening frame 6 containing the seeds to be processed is magnetically attached to the vertical rod 5. The vibration end of the multi-stage amplitude adjustment mechanism drives the vertical rod 5 to swing up and down repeatedly, so that the vertical rod 5 drives the screening frame 6 to swing up and down repeatedly. Under the action of the filter screen 3, the seeds in the screening frame 6 can be screened, and unqualified seeds, mixed dust and fine particles can be shaken off and discharged from the slag discharge port 4.

[0029] Specifically, the multi-stage amplitude adjustment mechanism includes a drive motor 71, a rotating shaft 72, a mounting plate 73, a top plate 74, a spring 75, a sliding sleeve 77, and at least two sets of eccentric block groups. The drive motor 71 is mounted on the upper end of the screening box 1 via a mounting base, and its output shaft is horizontally set and coaxially connected to the rotating shaft 72. The other end of the rotating shaft 72 is rotatably connected to the mounting plate 73. The eccentric block groups are fixedly sleeved on the rotating shaft 72. The lower end of the top plate 74 is fixedly connected to multiple vertical rods 5. Multiple sliding sleeves 77 are fixed on the upper end of the screening box 1. The vertical rods 5 pass through the corresponding sliding sleeves 77 and are slidably connected to them. The protrusions of the eccentric block groups can push the top plate 74 upward. The spring 75 is sleeved on the vertical rods 5, and one end of it is connected to a magnetic suction device, and the other end is connected to the top wall of the screening box 1.

[0030] The drive motor 71 is started, and its output torque is transmitted to the rotating shaft 72 through the coupling. The rotation of the rotating shaft 72 drives the eccentric block assembly to rotate. Since the protrusion of the eccentric block assembly can lift the top plate 74 upward, under the action of the spring 75, the rotation of the eccentric block assembly can cause the top plate 74 and the vertical rod 5 to move up and down reciprocally. The up and down reciprocating motion of the vertical rod 5 can cause the screening frame 6 to sway up and down. The sliding sleeve 77 can make the vertical rod 5 more stable when moving up and down.

[0031] More specifically, the eccentric block assembly includes a first eccentric block 761, a second eccentric block 762, and a fixing bolt 763. The first eccentric block 761 has through holes at equal intervals, and the second eccentric block 762 has threaded holes at equal intervals. The fixing bolt 763 passes through the through holes and extends into the threaded holes to be threadedly connected to them.

[0032] Different through holes are aligned with different threaded holes and fixed by fixing bolts 763, so that the radial direction of the first eccentric block 761 or the second eccentric block 762 is changed, thereby changing the eccentricity and adjusting the vibration amplitude.

[0033] Specifically, the magnetic attraction component includes an electromagnet 81 and a permanent magnet 82. The screening frame 6 has a groove that matches the permanent magnet 82. The electromagnet 81 is placed in the groove. The permanent magnet 82 is located at the lower end of the vertical rod 5 and is magnetically attracted to the electromagnet 81.

[0034] When electromagnet 81 is energized, the permanent magnet 82 attracts the electromagnet 81, thus fixing the screening frame 6 to the lower end of the vertical rod 5. A one-button unlocking function is added to automatically release the screening frame 6 when the power is off.

[0035] Specifically, the dust collection mechanism includes a vacuum cleaner 91 and an annular dust collection pipe 92. The vacuum cleaner 91 is connected to the annular dust collection pipe 92. The annular dust collection pipe 92 is horizontally installed on the inner side wall of the screening box 1 through a mounting bracket. The annular dust collection pipe 92 has multiple dust collection holes 93 facing the filter screen 3.

[0036] When the vacuum cleaner 91 is turned on, dust and fine particles in the screening box 1 are sucked in through the suction hole 93 and then into the vacuum cleaner 91 through the annular suction pipe 92. The annular suction pipe 92 forms an enveloping adsorption, which greatly improves the adsorption efficiency of dust and fine particles.

[0037] The working principle of this utility model:

[0038] Open the box door 2, energize the electromagnet 81, and the permanent magnet 82 magnetically attracts the electromagnet 81, attracting the screening frame 6 containing the seeds to be processed onto the vertical rod 5. Start the drive motor 71, and the output torque of the drive motor 71 is transmitted to the rotating shaft 72 through the coupling. The rotating shaft 72 rotates, causing the eccentric block group to rotate. Because the protrusion of the eccentric block group can lift the top plate 74 upward, under the action of the spring 75, the rotation of the eccentric block group can make the top plate 74 and the vertical rod 5 move up and down. The up and down movement of the vertical rod 5 can make the screening frame 6 sway up and down. Under the action of the filter screen 3, the seeds in the screening frame 6 can be screened, and unqualified seeds, mixed dust and fine particles can be shaken off and discharged from the slag discharge port 4.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
