Description

Technical Field

[0001] This utility model relates to the field of agricultural experimental technology, and in particular to a test seed collection device. Background Technology

[0002] With the vigorous development of agricultural scientific research, the scale and complexity of agricultural experiments continue to rise, and a variety of crop varieties are constantly being put into trials. The planting areas are expanding from regular small plots of land to large experimental fields with vast and varied terrains. Under this trend, the importance of collecting experimental varieties is becoming increasingly prominent. Accurate collection of experimental varieties is the basic guarantee for subsequent key scientific research links such as crop gene sequencing, variety characteristic comparison, and hybrid vigor assessment.

[0003] The agricultural experimental seed collection device mainly consists of a seed suction pipe, a power unit, a seed collection bin, and a filter assembly. When the device is started, the power unit drives the fan impeller to rotate at high speed, which creates negative pressure in the seed suction pipe. Mature experimental seeds, along with a small amount of dust and impurities, are sucked into the pipe. After being filtered by the filter screen, the impurities are intercepted, and the seeds fall into the seed collection bin for storage.

[0004] Current collection devices suffer from poor sieving performance and inability to effectively separate seeds from impurities. This makes it difficult to accurately separate experimental seeds from various impurities, resulting in substandard purity of collected seeds. Consequently, a significant amount of time is required for secondary sorting, which severely slows down the experimental progress and efficiency. Therefore, a new experimental seed collection device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a test seed collection device, which aims to improve the problems of poor screening effect and inability to effectively separate seeds and impurities in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A test species collection device includes a housing, a sieving mechanism for sieving is provided inside the housing, a cleaning mechanism for cleaning is provided inside the housing, and a collection mechanism for collecting is provided inside the housing.

[0008] The screening mechanism includes a second rotating column, which is rotatably connected to the outside of the housing. A second screen is fixedly connected to the outside of the second rotating column. A linkage rod is rotatably connected to the bottom end of the second screen. A first screen is rotatably connected to the bottom end of the linkage rod. A first rotating column is fixedly connected to the outside of the first screen. The outside of the first rotating column is rotatably connected to the inside of the housing. A transmission rod is rotatably connected to the top end of the second screen.

[0009] As a further description of the above technical solution:

[0010] The cleaning mechanism includes a motor, which is fixedly connected to the outside of the housing. A telescopic rod is fixedly connected to the drive end of the motor. A sliding rod is rotatably connected to the bottom end of the telescopic rod. Multiple telescopic scrapers are rotatably connected to the outside of the sliding rod.

[0011] As a further description of the above technical solution:

[0012] The housing has a sliding groove inside, and the sliding rod is slidably connected to the inside of the sliding groove.

[0013] As a further description of the above technical solution:

[0014] The bottom end of the telescopic scraper contacts the top end of the second screen, and the top end of the transmission rod is rotatably connected to the outside of the sliding rod;

[0015] As a further description of the above technical solution:

[0016] The collection mechanism includes a collection box one, the outside of which is slidably connected to the inside of the housing, and a collection box two is slidably connected to the inside of the housing;

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the linkage rod cleverly connects the two screens, forming a close linkage relationship. The transmission rod receives the power from the sliding rod and transmits it to one of the screens. The motor drives the telescopic rod, allowing the sliding rod to slide back and forth in the groove. The power is transmitted through the transmission rod and the linkage rod, causing the two screens to swing regularly within the shell. Compared with traditional single-screen sieving, this coordinated swing greatly improves the effect. During the swing, due to inertia and gravity, the test seeds and impurities move along different trajectories. Impurities of different sizes slide down the screen to one collection box, while qualified seeds pass through the screen holes and fall into the other collection box, preparing a purer and more accurately classified sample for subsequent experiments.

[0025] 2. In this utility model, the motor serves as the power source, driving the telescopic rod with telescopic characteristics to rotate, which in turn drives the connected sliding rod to slide smoothly in the sliding groove. The telescopic scraper connected to the sliding rod rotates and closely fits the top of the screen, sliding with the sliding rod to continuously and regularly scrape the screen. This scraping can promptly clean the impurities attached to the screen, avoid screen blockage, ensure a smooth screening process, and guarantee the stable and efficient operation of the device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a test seed collection device, comprising a housing 1, which serves as the outer shell of the entire device, protecting the internal structure and supporting other components. The housing 1 contains a sieving mechanism for effectively screening and separating the collected test seeds. The housing 1 also contains a cleaning mechanism for timely removal of impurities generated during the sieving process, maintaining the efficiency and accuracy of the sieving. Finally, the housing 1 contains a collection mechanism for classifying and collecting the sieving and cleaning test seeds.

[0034] The screening mechanism includes a rotating column 2 3, which is externally rotatably connected to the inside of the housing 1, providing stable support and a rotating shaft for the rotation of screen 2 5. Screen 2 5 is fixedly connected to the outside of the rotating column 2 3. Screen 2 5 is one of the important components of screening. Its aperture size is moderate, which can initially screen out larger impurities and smaller test species. The bottom end of screen 2 5 is rotatably connected to a linkage rod 6, and the bottom end of linkage rod 6 is rotatably connected to screen 1 4. Linkage rod 6 serves to connect screen 2 5 and screen 1 4, enabling them to move in coordination. The aperture of screen 1 4 is smaller than that of screen 2 5, which is used to further screen out smaller impurities, ensuring that the test species entering collection box 2 15 are purer. The outside of screen 1 4 is fixedly connected to a rotating column 2, which is externally rotatably connected to the inside of the housing 1, providing support and a rotating shaft for the rotation of screen 1 4. The top end of screen 2 5 is rotatably connected to a transmission rod 7, which is used to transmit power to screen 2 5, enabling it to rotate around rotating column 2 3.

[0035] The collection mechanism includes a collection box 14, which is externally slidably connected to the inside of the housing 1 for easy collection and removal of large and small impurities. Its capacity can be designed according to actual needs. A collection box 2 15 is slidably connected inside the housing 1. The collection box 2 15 is used to collect the sieved test samples. Its material should have good sealing and corrosion resistance to ensure the quality of the test samples. Two fans 13 are fixedly connected inside the housing 1. The fans 13 are the key components for generating suction. Through the pressure difference generated by rotation, the test samples are sucked into the collection pipe 16 and fall into the inside of the housing 1. Filter screens are fixedly connected to the outside of the two fans 13. The filter screens can prevent impurities from entering the inside of the fans 13 and protect the normal operation of the fans 13. The internal aperture of the sieve 2 5 is larger than that of the sieve 1 4. This design makes the sieving more precise and can effectively separate impurities and test samples of different sizes. A collection pipe 16 is fixedly connected to the rear end of the housing 1. The collection pipe 16 is the inlet for collecting test samples. Its length and diameter can be adjusted according to the actual use scenario.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The cleaning mechanism includes a motor 8, which serves as a power source and provides power support for the entire cleaning process. The motor 8 is externally fixedly connected to the outside of the housing 1 to ensure the stability and safety of the motor 8. A telescopic rod 9 is fixedly connected to the drive end of the motor 8. The telescopic rod 9 can extend, retract, and rotate under the drive of the motor 8, thereby driving the sliding rod 10 to move. The bottom end of the telescopic rod 9 is rotatably connected to the sliding rod 10. The sliding rod 10 slides back and forth inside the sliding groove 11 under the drive of the telescopic rod 9. Multiple telescopic scrapers 12 are rotatably connected to the outside of the sliding rod 10.

[0037] The bottom end of the telescopic scraper 12 contacts the top end of the second screen 5. Through reciprocating scraping action, it can promptly scrape impurities off the surface of the second screen 5 from the filter screen, preventing impurities from embedding into the mesh and keeping the filter screen unobstructed. This ensures that seeds can pass through stably during the collection process and maintains the continuity of the collection work. The top end of the transmission rod 7 is rotatably connected to the outside of the sliding rod 10, so that the movement of the sliding rod 10 can be transmitted to the second screen 5, realizing the rotation of the second screen 5. The outer sides of the first screen 4 and the second screen 5 are slidably connected to the inside of the housing 1, ensuring the stability and sealing of the first screen 4 and the second screen 5 during the rotation process. The outer side of the telescopic rod 9 is rotatably connected to the inside of the housing 1, further ensuring the smoothness and safety of the movement of the telescopic rod 9.

[0038] Working principle: When the operator needs to collect test seeds, he / she grasps the handle at the top of the shell 1 with one hand and the collection tube 16 with the other, aligning the collection port with the test seeds. By starting the blower 13, the pressure difference generated by the rotation of the blower 13 draws the test seeds into the collection tube 16 and into the interior of the shell 1. At this time, by starting the motor 8, the motor 8 drives the telescopic rod 9 to rotate, thereby causing the sliding rod 10 to slide back and forth inside the sliding groove 11. This causes the telescopic scraper 12 to scrape the top of the screen 5 back and forth. The continuous back-and-forth movement can promptly scrape these impurities away from the filter screen. The impurities are embedded in the mesh, keeping the filter screen unobstructed and ensuring that the seeds can pass through stably during the collection process, maintaining the continuity of the collection work.

[0039] As the sliding rod 10 slides back and forth inside the sliding groove 11, it drives the transmission rod 7 to rotate, causing the second screen 5 to rotate around the second rotating column 3. Through the rotational connection of the linkage rod 6, the first screen 4 will rotate around the first rotating column 2 as the rotating axis, thus achieving the effect of multi-stage sieving. Large and small impurities will fall into the collection box 14 for collection as they swing back and forth. The test seeds will fall into the collection box 15 for collection through the apertures of the first screen 4 and the second screen 5, thus achieving the effect of pre-treatment of the test seeds and improving the purity of the seeds.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
