Description

Technical Field

[0001] This utility model relates to the technical field of seed screening devices, and in particular to a seed screening device for cultivating honeysuckle fruit varieties. Background Technology

[0002] Honeysuckle berries, a type of berry with high nutritional and economic value, are rich in various vitamins, minerals, and bioactive components, and have broad application prospects in the food, medicine, and health product industries. Therefore, the cultivation of high-quality honeysuckle berry varieties is crucial for promoting the development of related industries, and seed selection is a key initial step in the variety cultivation process.

[0003] Existing technology discloses a seed screening and drying device for forestry planting, application number 202321781481.5, including a screening device, a feeding device at the top of the screening device, and a drying device on the screening device. This utility model provides a seed screening and drying device for forestry planting. Through the feeding device, seeds for forestry planting are temporarily stored in a feeding hopper. Through the screening device, an auger continuously conveys the seeds, which are then screened through a sieve cylinder. Simultaneously, through the drying device, a hot air blower dries the seeds. This device has a simple structure and can simultaneously screen and dry seeds for forestry planting. The continuous movement of the seeds during auger conveying improves the screening and drying efficiency. However, existing technologies still lack comprehensive purification measures for pollutants such as dust, odors, and harmful microorganisms generated during the screening process of honeysuckle berry seeds. This not only pollutes the environment and endangers the health of operators but also affects seed quality. The fixed angle of the sieve cylinder makes it difficult to adjust flexibly according to the characteristics of honeysuckle berry seeds and screening requirements, thus limiting screening accuracy and efficiency. During drying, the hot airflow from the hot air blower is unidirectional and cannot be adjusted, easily causing uneven drying of seeds and reducing seed activity and germination rate. Furthermore, the purification mechanism is not rationally designed with a clean airflow direction, resulting in insufficient contact between the purified airflow and the purification plate, leading to poor purification effect and an inability to create a clean screening environment. Therefore, we propose a seed screening device for honeysuckle berry cultivation to solve the above problems. Utility Model Content

It also possesses good flexibility and applicability, meeting the seed screening needs under different conditions.

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

The servo motor is fixedly installed on one side of the base, and its output end is connected to a threaded rod. A threaded sleeve is threaded onto the threaded rod, and a fixing plate is fixedly installed at the upper end of the threaded sleeve. A connecting rod is provided between the fixing plate and the outer cylinder. The two ends of the connecting rod are respectively provided with a first hinge seat and a second hinge seat. The connecting rod is connected to the outer cylinder through the first hinge seat and to the fixing plate through the second hinge seat. Symmetrical support side plates are provided on both the front and rear sides of the middle section of the outer cylinder. The outer cylinder is connected by a support shaft; a connecting plate is fixedly installed on the lower right side of the outer cylinder, and a support column is fixedly installed on the upper end of the base. A rotating shaft is provided through the support column near the top, and the front and rear ends of the rotating shaft are movably connected to the connecting plates; the output end of the drive motor is connected to the drive shaft, and an auger blade is installed on the drive shaft; a screen cylinder is also provided inside the outer cylinder, and a discharge port is provided at the bottom of the screen cylinder. The top of the outer cylinder corresponds to the feed port; an exhaust hood is provided at the upper right end of the outer cylinder, and the exhaust hood is connected to the purification mechanism through a connecting pipe. The purification mechanism includes a purification box, and a purification plate one, a purification plate two, and a purification plate three are arranged in sequence inside the purification box; a hot air fan is provided on the left side of the outer cylinder, and the hot air fan is connected to the outer cylinder through a hot air pipe.

[0007] Furthermore, the two ends of the threaded rod are rotatably mounted on the base via bearing seats, and the threaded rod is arranged parallel to the slot on the base.

[0008] Furthermore, the fixing plate is a rectangular plate structure, and its length is adapted to the length of the sieve cylinder.

[0009] Furthermore, the sieve cylinder is a cylindrical mesh structure, and the mesh size is set according to the screening requirements of honeysuckle seeds. The sieve cylinder is open at both ends, with one end corresponding to the feed inlet and the other end corresponding to the discharge outlet.

[0010] Furthermore, the first purification plate is an activated carbon adsorption plate, the second purification plate is a HEPA filter plate, and the third purification plate is an ultraviolet sterilization plate.

[0011] Furthermore, the hot air duct is equipped with an airflow regulating valve.

[0012] Furthermore, the auger blades are spirally wound around the drive shaft, and the outer diameter of the auger blades is smaller than the inner diameter of the sieve cylinder. The drive shaft is installed in the outer cylinder through a bearing seat, and the drive motor drives the drive shaft and the auger blades to rotate, pushing the seeds to move and be screened inside the sieve cylinder.

[0013] Furthermore, the feed cylinder has a funnel-shaped structure with a large opening at the top and the bottom connected to the feed inlet; the discharge port is inclined downwards.

[0014] Furthermore, the diameter of the sieve holes on the sieve cylinder increases sequentially from left to right.

[0015] Furthermore, the auger blades are provided with a number of evenly distributed air vents.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. Highly Efficient and Comprehensive Purification: The purification mechanism of this invention sequentially incorporates an activated carbon adsorption plate, a HEPA filter plate, and an ultraviolet sterilization plate, effectively treating odors, impurities, fine particles, bacteria, and microorganisms. Simultaneously, through a rationally designed exhaust hood, connecting pipes, and airflow channels within the purification chamber, polluted gases are ensured to fully contact the purification plates. This ensures the direction of the purified airflow enhances the purification effect, achieving comprehensive purification of gases generated during the screening process. This provides a clean environment for honeysuckle seed screening, protecting seed quality and the health of operators.

[0018] 2. Flexible Angle Adjustment: A servo motor drives the threaded rod to rotate, causing the threaded sleeve to move up and down. This changes the connection between the fixed plate and the outer cylinder via the connecting rod, allowing for flexible adjustment of the sieve cylinder angle. The tilt angle of the sieve cylinder can be precisely adjusted according to the characteristics and screening requirements of different batches of honeysuckle berry seeds, ensuring more thorough contact between the seeds and the sieve openings, improving screening accuracy and efficiency, and meeting diverse screening needs.

[0019] 3. Controllable airflow direction: The airflow regulating valve on the hot air duct can not only adjust the hot air volume, but also, in conjunction with the structure of the outer cylinder and sieve cylinder, control the airflow direction of the hot air to a certain extent. Based on the distribution of seeds within the sieve cylinder and drying requirements, the hot air volume and airflow direction can be flexibly adjusted, ensuring that the hot air acts evenly on the seeds, achieving precise drying, guaranteeing uniform seed drying, and improving seed activity and germination rate.

[0020] 4. Optimized Purified Airflow Direction: This device features an optimized design for the direction of the purified airflow. Through a rational layout of the exhaust hood, connecting pipes, and the internal space of the purification chamber, the purified airflow is guided to pass through the purification plates in an orderly manner, ensuring full contact between the airflow and the plates, thereby improving purification efficiency and effectiveness.

[0021] In summary, the seed screening device for this honeysuckle berry cultivation variety has broad applicability, addressing the shortcomings of existing technologies mentioned in the background section. These technologies lack comprehensive purification measures for pollutants such as dust, odors, and harmful microorganisms generated during honeysuckle berry seed screening, which pollute the environment, endanger the health of operators, and affect seed quality. Furthermore, the fixed angle of the sieve cylinder makes it difficult to adjust flexibly according to the characteristics of honeysuckle berry seeds and screening requirements, resulting in limited screening accuracy and efficiency. During drying, the hot airflow from the hot air blower has a unidirectional and unadjustable direction, easily causing uneven drying of seeds, reducing seed activity and germination rate. Additionally, the purification mechanism is not rationally designed with a clean airflow direction, resulting in insufficient contact between the purified airflow and the purification plate, poor purification effect, and an inability to create a clean screening environment.
