Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, and in particular to a seed washing device for seed screening. Background Technology

[0002] Seed selection is a crucial step in agricultural production and breeding research. The cleanliness, purity, and surface cleanliness of seeds directly affect germination rate, seedling uniformity, and subsequent crop yield. This is especially true for economic crops like blue honeysuckle, which have both medicinal and edible value. Their seeds are small, easily covered with fruit pulp residue and fine hairs, and have thin seed coats that are sensitive to mechanical damage. If impurities and surface dirt are not thoroughly removed before sowing, the accuracy of sowing density will be reduced, leading to a sharp drop in blue honeysuckle seed germination rate and severely impacting seedling quality and subsequent fruit yield. Existing seed screening devices are mostly based on single-grade screening, which only classifies seeds by the difference in filter pore size. They lack the function of cleaning the seed surface. For blue honeysuckle seeds, additional manual rubbing or separate cleaning equipment is required, which is cumbersome and inefficient. Some devices that integrate rubbing function use a single rotating stirring shaft for rubbing. The stirring trajectory is fixed and the rubbing force is uneven. This can easily lead to incomplete cleaning of the fuzz and pulp residue on the surface of blue honeysuckle seeds. It may also cause seed coat damage due to rigid collision, affecting the continuity and efficiency of screening. At the same time, rubbing and screening are carried out in separate steps, with many manual interventions and high labor intensity. It is difficult to meet the needs of blue honeysuckle breeding experiments or large-scale planting for efficient and precise seed treatment.

[0003] Therefore, a seed washing device for seed screening is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-4 This utility model provides a seed washing device for seed screening, comprising: Box 1, with a detachable sealed door 2 on one side, a discharge assembly installed at the bottom, and brackets 3 installed on the two opposite inner side walls of box 1; The filter assembly includes a first filter 4 and a second filter 5. Both the first filter 4 and the second filter 5 are detachably connected to the inner wall of the housing 1. The first filter 4 is located above the second filter 5, and the pore size of the first filter 4 is larger than that of the second filter 5. The planetary stirring mechanism includes a drive assembly and two stirring shafts 6. The drive assembly is mounted on the top of the housing 1. The output end of the drive assembly is connected to a large gear 7. The two stirring shafts 6 are rotatably connected to two brackets 3 respectively. A driven gear 8 is mounted on the top of the stirring shaft 6. The driven gear 8 meshes with the large gear 7 for transmission. Several brush assemblies are mounted on the bottom of the stirring shaft 6. The bottom of the brush assemblies is in contact with the surface of the first filter screen 4. The nozzle assembly consists of two sets, which are respectively mounted on two brackets 3. The nozzle assembly is connected to a liquid supply device through a liquid supply pipe 14. With this configuration, the present invention drives the large gear 7 to rotate via the drive component, and the driven gear 8 meshing with the large gear 7 drives the two stirring shafts 6 to rotate synchronously, thereby driving the two sets of brush body components to rotate, performing a scrubbing operation on the blue honeysuckle seeds, achieving efficient removal of pulp residue, fine hairs and other dirt from the seed surface; in conjunction with two sets of symmetrically installed nozzle components, it washes away the fine impurities that fall off the surface of the blue honeysuckle seeds in real time, greatly improving the cleanliness of the seed surface and providing a clean environment for subsequent germination; This invention uses a first filter screen 4 to trap large particles of impurities in honeysuckle seeds, while simultaneously using a brush assembly to perform initial seed washing. Seeds filtered through the first filter screen 4 fall into a second filter screen 5, where smaller particles and seeds of unsuitable particle size are further separated. Seeds meeting the particle size requirements are retained at the top of the second filter screen 5 and removed through the sealed door 2. The filter assembly is detachable, facilitating later cleaning of clogged impurities or replacement with filters of different pore sizes, thus improving the device's adaptability and ease of maintenance. This utility model integrates washing, screening, and spraying functions into one unit. The liquid supply device continuously supplies liquid to the nozzle assembly, and the planetary stirring mechanism automatically completes the washing action of the blue honeysuckle seeds. The seeds can be cleaned and graded without manual intervention. The sealed door 2 facilitates the loading and unloading of seeds, and the discharge assembly at the bottom can quickly discharge impurities, simplifying the operation process, greatly improving the processing efficiency of blue honeysuckle seeds, and reducing labor intensity. It is especially suitable for fine seed processing in blue honeysuckle breeding experiments or batch seed pretreatment before large-scale planting.

[0020] The design has been further optimized by installing a vibration motor 9 at the bottom of the second filter screen 5; The vibration motor 9 is connected to the control system (not shown in the figure). The control system uses a microcontroller or PLV. After the vibration motor 9 is started, it generates high-frequency micro-vibration. The vibration energy is transmitted to the second filter screen 5 through the connector. The vibration of the vibration motor 9 can make the second filter screen 5 shake slightly up and down or left and right. On the one hand, it can shake off the blue honeysuckle seeds or impurities stuck in the filter screen pores, avoid clogging of the second filter screen 5, and ensure that the seeds that meet the requirements are stably retained on the top of the second filter screen 5. Small particles of impurities can pass through the second filter screen 5 smoothly and fall into the bottom of the box 1. On the other hand, the vibration can accelerate the flattening of seeds on the surface of the second filter screen 5, prevent local accumulation of seeds, make the screening more uniform, and avoid the interruption of the experiment caused by manual cleaning of the filter screen, thus improving the continuity of batch processing of blue honeysuckle seeds.

[0021] Further optimization of the scheme: the drive component includes two motors 10 arranged side by side. The motors 10 are mounted on the top of the housing 1. The output shaft of the motors 10 extends into the housing 1. The output shaft of the motors 10 is equipped with drive wheels 11. The large gear 7 is rotatably connected to the inner top wall of the housing 1 through a central rotating shaft. An intermediate gear is mounted on the central rotating shaft. The intermediate gear is located above the large gear 7. Both drive wheels 11 mesh with the intermediate gear for transmission.

[0022] The solution is further optimized. The nozzle assembly includes a water collection plate 12, which is mounted on a bracket 3. Several nozzles 13 are mounted on the water collection plate 12, and the nozzles 13 are connected to the water collection plate 12. The water collection plate 12 is connected to the liquid supply equipment through a liquid supply pipe 14. The liquid supply device delivers rinsing water to the water collection plate 12 through the liquid supply pipe 14. The water collection plate 12 has a hollow structure, which can evenly distribute the water flow to several nozzles 13 on the plate. In view of the characteristic that fine hairs and pulp residues are easily attached to the surface of honeysuckle seeds, multiple nozzles 13 are evenly arranged along the water collection plate 12, which can reduce the spray blind area, effectively wash away impurities that fall off the seed surface, and improve the cleaning effect.

[0023] Further optimization of the design: the brush body assembly includes a connecting rod 15, which is installed at the bottom of the stirring shaft 6. A connecting seat 16 is installed at the end of the connecting rod 15 away from the stirring shaft 6. A stirring rod 17 is detachably connected to the connecting seat 16. The stirring rod 17 is inclined. Two wing plates 18 are installed at the end of the stirring rod 17 away from the connecting seat 16. A brush body 19 is detachably connected between the two wing plates 18. The brush body 19 contacts the upper surface of the first filter screen 4. The inclined stirring rod 17 can increase the contact area with the blue honeysuckle seeds. The brush body 19 between the two wing plates 18 is made of flexible material and makes gentle contact with the upper surface of the first filter screen 4. When the stirring shaft 6 rotates, the brush body 19 can not only peel off the pulp residue and hair on the seed surface, but also avoid rigid friction damage to the seed coat.

[0024] The design has been further optimized by providing a protective cover 20 around the large gear 7 and the two driven gears 8. This can prevent impurities from entering the gear area, ensuring smooth gear transmission and extending the service life of the transmission components.

[0025] The scheme is further optimized. The discharge component includes a discharge pipe 21 installed at the bottom of the box 1, and a valve is installed on the discharge pipe 21. When the screening is completed or the impurities at the bottom of the box 1 accumulate to a certain amount, the valve is opened and the impurities and wastewater are discharged in a concentrated manner through the discharge pipe 21. There is no need to disassemble the box 1 for cleaning, which simplifies the operation process.

[0026] The design has been further optimized by installing a handle 22 and a viewing window 23 on the sealed door 2 to improve ease of operation.
