Description

Technical Field

[0001] This utility model belongs to the field of Chinese medicinal herb cultivation technology, specifically relating to a seed screening device for Chinese medicinal herb cultivation. Background Technology

[0002] Currently, many Chinese herbal medicine varieties have been developed for artificial cultivation. When cultivating Chinese herbal medicine, it is important to pay attention to these points: selecting high-quality seeds can improve the germination rate. Existing seeds used for Chinese herbal medicine cultivation need to be screened by a sieving device to separate the seeds by size.

[0003] However, existing screening devices can only classify seeds according to their shape and size, but large, shriveled seeds will still be mixed in after screening. These seeds are light and not plump enough, which affects the planting quality. The screen of the screening device alone cannot screen the seeds according to their weight and plumpness. In addition, the existing screening devices have low production continuity. Utility Model Content

[0004] To overcome the problem that existing seed screening devices can only classify seeds based on shape and size, and cannot effectively separate them based on weight and plumpness, this invention provides a seed screening device for Chinese herbal medicine cultivation. This device combines air separation and vibration screening to perform multi-stage sorting of seeds, effectively removing large, shriveled seeds and other impurities, while also enabling continuous operation and improving screening efficiency and quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A seed screening device for planting Chinese herbal medicines mainly includes a frame, an air separator, a feed hopper, a diverter plate, an air separator mechanism, a discharge trough, a slag discharge component, and a vibrating screening mechanism. The air separator is fixedly installed on the top of the frame, and the interior of the air separator is set as a cavity structure. The feed hopper is fixedly installed on the top of the air separator and communicates with the interior of its cavity structure. The diverter plate is installed obliquely inside the air separator and located directly below the feed hopper. The air separator mechanism is fixedly installed on the top of the air separator and communicates with the interior of the air separator through a pipe.

The air separation mechanism includes fans, air supply hoses, and an air collection hood. Two fans are fixedly installed at the top of the air separation box, and the air collection hood is fixedly installed inside the air separation box at the end of the diverter plate. One end of the air supply hose is connected to the air outlet of the fan, and the other end passes through the bottom of the air separation box and connects to the air collection hood. The airflow generated by the fans is delivered to the air collection hood through the air supply hoses, forming a directional airflow that blows lighter, shriveled seeds and impurities into the slag discharge assembly. The slag discharge assembly includes a guide plate, a slag discharge plate, and a slag discharge trough. The guide plate is fixedly installed inside the air classifier and is configured as an inverted V-shape. The slag discharge plate is installed at an angle at the end of the guide plate. A slag discharge port is opened on the side wall of the air classifier, and the slag discharge trough is fixedly installed at the slag discharge port. Lighter, shriveled seeds and impurities slide down the guide plate to the slag discharge plate and are discharged from the air classifier through the slag discharge trough. The vibrating screening mechanism includes a support frame, a screening box, springs, a screen, a vibrating motor, and a discharge chute. The support frame is fixedly installed below the air-separating box. The screening box is mounted on top of the support frame via springs. The screen is fixedly installed inside the screening box, dividing it into upper and lower layers. The vibrating motor is fixedly installed at the bottom of the screening box, and the discharge chute is fixedly installed at the end of the screening box.

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0013] This utility model discloses a seed screening device for planting traditional Chinese medicinal herbs. The device mainly includes a frame 1, an air separator 2, a feed hopper 3, a diverter plate 4, an air separation mechanism 5, a discharge trough 6, a slag discharge assembly 7, and a vibrating screening mechanism 8. The frame 1 serves as the main support for the entire device and is made of metal, providing strong stability and load-bearing capacity. The air separator 2 is fixedly installed at the top of the frame 1 and has a hollow internal structure for initial seed separation. A transparent observation window 21, made of tempered glass, is provided on the side wall of the air separator 2, allowing operators to observe the internal workings of the chamber in real time. The feed hopper 3 is fixedly installed at the top of the air separator 2 and communicates with the hollow structure of the air separator 2, guiding the seeds to be screened into the air separator 2. A first baffle 31 is installed at an angle below the feed hopper 3, guiding the seeds to slide down to the diverter plate 4 in a designated direction. Diverter plate 4 is installed at an angle inside air separator 2, directly below feed hopper 3. The lower end of diverter plate 4 is flush with second baffle 32. Second baffle 32 is fixedly installed inside air separator 2 to prevent seeds from scattering and ensure that seeds can enter the subsequent sorting process smoothly. The air separation mechanism 5 includes a blower 51, a flexible air supply hose 52, and an air collection hood 53. Two blowers 51 are fixedly installed at the top of the air separation box 2. The air outlets of the blowers 51 are connected to the air collection hood 53 via the flexible air supply hose 52. The air collection hood 53 is fixedly installed inside the air separation box 2, located at the end of the diverter plate 4. The airflow generated by the blowers 51 is delivered to the air collection hood 53 through the flexible air supply hose 52, forming a directional airflow. When the seeds slide down the diverter plate 4, the directional airflow blows the seeds away, and lighter, shriveled seeds and impurities are blown away by the airflow and slide down the guide plate 71 to the slag discharge assembly 7. The slag discharge assembly 7 includes a guide plate 71, a slag discharge plate 72, and a slag discharge trough 73. The guide plate 71 is fixedly installed inside the air separation box 2 and has an inverted V-shaped structure, used to guide the lighter seeds and impurities blown away by the airflow to slide down to the slag discharge plate 72. The slag discharge plate 72 is installed at an angle at the end of the guide plate 71. A slag discharge port is provided on the side wall of the air classifier 2. The slag discharge trough 73 is fixedly installed at the slag discharge port to discharge light seeds and impurities from the air classifier 2. The air separator 2 has a feeding port at its bottom, and a feeding trough 6 is fixedly installed at the feeding port to guide the air-separated seeds into the vibrating screening mechanism 8. The vibrating screening mechanism 8 is installed at the bottom of the air separator 2, directly below the feeding trough 6. The vibrating screening mechanism 8 includes a support frame 81, a screening box 82, a spring 83, a screen 84, a vibrating motor 85, and a discharge trough 86. The support frame 81 is fixedly installed directly below the air separator 2 to support the entire vibrating screening mechanism 8. The screening box 82 is installed on top of the support frame 81 by the spring 83, which ensures the stability of the screening box 82 during vibration. The screen 84 is fixedly installed inside the screening box 82, dividing the screening box 82 into upper and lower layers. The vibrating motor 85 is fixedly installed at the bottom of the screening box 82 to drive the screening box 82 to vibrate. When the seeds enter the screening box 82, they are graded on the screen 84 under the action of the vibrating motor 85. Smaller seeds fall through screen 84 into the lower layer of screening box 82 and are discharged through the second discharge chute 862; larger seeds remain in the upper layer of screening box 82 and are discharged through the first discharge chute 861. The first discharge chute 861 and the second discharge chute 862 are respectively connected to the upper and lower layers of screening box 82 for classifying and collecting seeds of different sizes. Work process: In practical applications, the operator first pours the seeds to be screened into the feed hopper 3. The seeds slide down the first baffle 31 to the diversion plate 4 and are evenly distributed on the diversion plate 4. The design of the diversion plate 4 prevents the seeds from accumulating during the sliding process, while the second baffle 32 prevents the seeds from scattering, ensuring that the seeds smoothly enter the air separation area of ​​the air separator 2. At this time, the blower 51 starts and delivers airflow to the air collecting hood 53 through the air supply hose 52. The directional airflow released by the air collecting hood 53 blows the seeds. Because the plump seeds have a larger mass, they are less affected by the airflow and will slide down through the discharge port to the discharge trough 6; while the lighter, shriveled seeds and impurities are blown away by the airflow, slide down the guide plate 71 to the slag discharge plate 72, and are discharged from the air separator 2 through the slag discharge trough 73.

[0014] After air separation, the seeds enter the screening box 82 of the vibrating screening mechanism 8 through the feeding chute 6. At this time, the vibration motor 85 starts, driving the screening box 82 to generate high-frequency vibration. The seeds are graded on the screen 84. Smaller seeds fall through the screen 84 into the lower layer of the screening box 82 and are discharged through the second discharge chute 862; larger seeds remain in the upper layer of the screening box 82 and are discharged through the first discharge chute 861. Through the above process, the seeds are sorted in multiple stages according to weight, plumpness, and size.

[0015] The transparent observation window 21 allows operators to observe the working conditions inside the air separator 2 in real time. Through the transparent observation window 21, operators can intuitively judge the flow state and sorting effect of the seeds, and thus adjust the power of the blower 51 or the frequency of the vibrating motor 85 in a timely manner to optimize the screening effect. In addition, the cooperative design of the first baffle 31 and the second baffle 32 further improves the stability of seed flow and avoids the problem of seed accumulation or scattering on the diverter plate 4.

[0016] Through the above steps, this invention achieves multi-stage seed sorting. The air-separating mechanism 5 uses airflow to separate lighter, shriveled seeds and impurities, while the vibrating screening mechanism 8 uses a sieve 84 to grade the seeds by size, ultimately ensuring that the sorted seeds have high plumpness and uniformity. The installation methods and connections between the components are clearly defined, the overall structure is compact, and the operation is simple, significantly improving screening efficiency and quality, and meeting the demand for high-quality seeds in the cultivation of traditional Chinese medicinal herbs.

[0017] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
