Description

Technical Field

[0001] This invention relates to the field of seed testing equipment technology, specifically to a device for testing the abrasion resistance of beet pellet seeds. Background Technology

[0002] Seed pelleting technology utilizes specialized equipment and a layered coating principle to coat the surface of seeds with environmentally friendly polymer materials. This alters seed shape, increases seed volume, promotes germination and plant growth, and improves sowing efficiency. It can also carry more active ingredients such as pesticides and nutrients needed for crop growth. Pelleted seeds are distinct, avoiding uneven sowing and enabling automated, easy sowing. Compared to traditional bare-seed sowing, it can save at least one-third of the seed usage. Furthermore, the pellet coating layer has water-retaining and insect-proof functions. During pelleting, the coating layer provides a favorable microenvironment for seed germination, improving seed resistance and seedling quality. However, during subsequent stages such as packaging, transportation, and sowing, the coating layer can detach due to friction and impact, affecting its effectiveness. Therefore, standardized testing of the abrasion resistance (or breakage rate) of pelleted seeds is a crucial aspect of quality control.

[0003] Currently, there is no equipment specifically designed for abrasion resistance testing of pelleted seeds. After testing the abrasion resistance of pelleted seeds with a roller, the coating powder remaining on the inner wall of the roller needs to be manually cleaned. Failure to clean it in time will affect the accuracy of subsequent tests. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-13 The present invention provides a technical solution: A device for testing the abrasion resistance of beet pelleted seeds, as per the instruction manual. Figure 1 As shown, it includes: Roller 1, roller 1 is provided with a test chamber 101; The drive assembly is used to drive the roller 1 to rotate; The collision assembly includes a protrusion mechanism and a fixing mechanism. The protrusion mechanism is used to collide with the pelletized seed during testing, and the fixing mechanism is used to fix the protrusion mechanism. The cleaning assembly includes an impact air storage mechanism, an energy storage mechanism, a storage mechanism, a jetting mechanism, and a dust collection mechanism. The impact air storage mechanism is used to compress air when the protruding mechanism and the pelletized seeds collide. The energy storage mechanism is used to convert the energy of the impact between the protruding mechanism and the pelletized seeds into electrical energy. The storage mechanism is used to store the compressed air and the electrical energy generated by the energy storage mechanism and supply it to the jetting mechanism. The jetting mechanism is used to clean the dust adhering to the side wall of the test chamber 101. The dust collection mechanism is used to collect the dust inside the test chamber 101.

[0020] The test chamber 101 is sealed by the end cap 2 during use. The end cap 2 is used to seal the test chamber 101 during abrasion resistance testing to prevent the seeds from flying out during the test. A fixed bracket 102 is provided on the outside of the roller 1. The fixed bracket 102 is used to limit the roller 1. The roller 1 is rotatably connected to the fixed bracket 102. The roller 1 is made of acrylic material.

[0021] The drive assembly includes a servo motor 3 and a flexible coupling 4. The servo motor 3 is connected to the roller 1 through the flexible coupling 4. The servo motor 3 can precisely control the rotation speed of the roller 1 to meet the requirements of seed abrasion resistance testing under different test conditions. The flexible coupling 4 plays a role in buffering and shock absorption, reducing the impact force on the roller 1 when the motor is running, and ensuring the stability of the test process.

[0022] The protrusion mechanism includes a rubber protrusion 5. The surface of the rubber protrusion 5 is specially treated to have appropriate hardness and roughness, which can realistically simulate the friction and impact encountered by the seeds in actual use when colliding with pelleted seeds, providing a strong guarantee for the accurate testing of seed abrasion resistance. The rubber protrusion 5 is connected to the inner wall of the test chamber 101, and the fixing mechanism is used to fix the rubber protrusion 5.

[0023] The test chamber 101 has several mounting holes. The fixing mechanism includes a ring magnet 6 and an electromagnet 7. A ring magnet 6 is provided on one side of the rubber protrusion 5. The ring magnet 6 is sleeved on the side of the rubber protrusion 5 near the mounting hole. Through cooperation with the electromagnet 7, the rubber protrusion 5 is firmly fixed. The electromagnet 7 is set in the mounting hole. In use, the installation and removal of the rubber protrusion 5 can be realized by controlling the energization and de-energization of the electromagnet 7. When the electromagnet 7 is energized, the electromagnet 7 and the ring magnet 6 attract each other to fix the rubber protrusion 5.

[0024] The impact-storage mechanism includes a flexible rod 8, a piston block 9, a cylinder 10, and a return spring 11. A rubber protrusion 5 connects to the flexible rod 8, which is made of plastic and can only bend axially during use, not extend. One end of the flexible rod 8 is fixedly connected to the piston block 9, which is slidably connected to the cylinder 10. The return spring 11 is fixedly connected to both ends of the cylinder 10 and the piston block 9. When the rubber protrusion 5 collides with and moves in relation to the pelletized seeds, it causes the flexible rod 8 to shift, which in turn pushes the piston block 9 within the cylinder 10. During this process, the air within the cylinder 10 is rapidly compressed, and the return spring 11 acts as a buffer and restores the piston's position. When the collision ends, the return spring 11 pushes the piston block 9 and the flexible rod 8 back to their initial positions.

[0025] The energy storage mechanism includes a connecting rod 12, a pressing block 13, a housing 14, and a piezoelectric ceramic block 15. The connecting rod is inserted into the cylinder 10. The two ends of the connecting rod 12 are respectively connected to the piston block 9 and the pressing block 13. The pressing block 13 is movably connected to the housing 14. The housing 14 is designed to protect the internal piezoelectric ceramic block 15 from damage and to restrict the movement direction of the pressing block 13. The piezoelectric ceramic block 15 is connected inside the housing 14. When the connecting rod 12 drives the pressing block 13 to move, the pressing block 13 will continuously press the piezoelectric ceramic block 15. After being pressed, the piezoelectric ceramic block 15 will generate an electrical signal, thereby converting mechanical energy into electrical energy. The battery 17, as an electrical energy storage unit, is electrically connected to the piezoelectric ceramic block 15 and can receive and store the electrical energy converted by the energy storage mechanism.

[0026] The storage mechanism includes an annular air pipe 16 and a battery 17. The annular air pipe 16 is connected to several cylinders 10. The design of the annular air pipe 16 allows the compressed air from each cylinder 10 to converge and be stored, forming a unified air supply system. The annular air pipe 16 is equipped with a safety valve. During pressure testing, if the pressure inside the annular air pipe 16 exceeds the set value, the safety valve will automatically open to release excess gas and prevent equipment damage due to excessive pressure. The battery 17 is electrically connected to the piezoelectric ceramic block 15. The battery 17 is equipped with a rectifier, which can rectify and store the electrical energy generated by the piezoelectric ceramic block.

[0027] The injection mechanism includes a solenoid valve 18, an injection pipe 19, a nozzle 20, and a return spring 21. The solenoid valve 18 is connected to the side wall of the test chamber 101. As a control element, the solenoid valve 18 can precisely control the flow of compressed air. When the solenoid valve 18 is open, compressed air is allowed to be transmitted to the nozzle 20 through the injection pipe 19. The battery 17 is used to power the solenoid valve 18. The injection pipe 19 is connected to the solenoid valve 18, and the nozzle 20 is movably connected to the injection pipe 19. Compressed air is introduced into the injection pipe 19 to cause the nozzle 20 to extend out of the injection pipe. 19. The nozzle 20 has multiple spray holes at different angles, which can spray compressed air or high-pressure airflow at different angles after the solenoid valve 18 is opened, to clean the side wall of the test chamber 101 and the adjacent rubber protrusions 5. The reset spring 21 is used to drive the nozzle 20 to reset. The reset spring 21 is installed at the connection between the nozzle 20 and the spray pipe 19. When the solenoid valve 18 is closed and the spraying action is over, the reset spring 21 will pull the nozzle 20 back to the initial position by its own elastic force, preparing for the next spray.

[0028] The dust collection mechanism includes a negative pressure generator 22, a dust collection rod 23, a dust collection box 24, and a dust collection screen 25. During dust collection, the dust collection rod 23 is inserted into the test chamber 101 and connected to the dust collection box 24. The dust collection box 24 is equipped with a dust collection screen 25, which is used to prevent dust from entering the negative pressure generator 22. The negative pressure generator 22 is used to generate negative pressure inside the dust collection box 24. After the negative pressure generator 22 is started, it can form a stable negative pressure environment inside the dust collection box 24, so that the dust in the test chamber 101 is quickly sucked into the dust collection rod 23 under the action of negative pressure.

[0029] Working principle: When conducting seed abrasion resistance testing, the pelleted seeds to be tested are first placed into the test chamber 101 of the roller 1, and then the test chamber 101 is sealed by the end cap 2. The drive assembly is activated, and the servo motor 3 drives the roller 1 to rotate via the flexible coupling 4, causing the pelleted seeds to roll within the test chamber 101. In this embodiment, during each test, the servo motor 3 drives the roller 1 to rotate around a common axis at a speed of 500 revolutions per minute, and the rotation is performed according to a set time. As the roller 1 rotates, the pelleted seeds collide with the protruding mechanism (i.e., rubber protrusions 5) in the collision assembly, realistically simulating the friction and impact encountered by seeds during actual use. During the collision, the rubber protrusions 5 are connected to a flexible rod 8, which drives the piston block 9 to move within the cylinder 10, rapidly compressing the air within the cylinder 10 to achieve the impact-storage function. When the piston block 9 moves, it drives the connecting rod 12 to move, thereby causing the pressing block 13 to press the piezoelectric ceramic block 15. The piezoelectric ceramic block 15 generates an electrical signal, converting mechanical energy into electrical energy. The annular air pipe 16 in the storage mechanism gathers and stores the compressed air from each cylinder 10, while the battery 17 receives and stores the electrical energy converted by the energy storage mechanism.

[0030] When cleaning is required, the solenoid valve 18 is opened, and compressed air is sprayed out from multiple spray holes at different angles of the nozzle 20 through the spray pipe 19 to thoroughly clean the side wall of the test chamber 101. During the cleaning process, the dust collector is inserted into the test chamber 101, and the negative pressure generator 22 generates negative pressure inside the dust collection box 24. The dust blown up by the nozzle 20 in the test chamber 101 is quickly sucked into the dust collection rod 23 under the action of negative pressure, and then enters the dust collection box 24.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
