Description

Technical Field

[0001] This utility model relates to the field of seed sterilization technology, specifically a seed sterilization device. Background Technology

[0002] To prevent the growth and spread of bacteria attached to rice seeds during storage, the seeds usually need to be sterilized before being stored in the warehouse. At present, the industry generally uses the chemical soaking sterilization method. This method involves immersing the seeds in a sterilization solution to ensure that the solution is in full contact with the seed surface, thereby achieving the purpose of killing pathogens. To ensure that all seeds remain in uniform contact with the solution after the solution level drops due to seed absorption, a sufficient or even excessive amount of solution must be injected initially. Therefore, when separating the solution from the seeds after soaking, the seeds are tightly packed, resulting in poor internal pore connectivity. Furthermore, the lower layer of seeds is subjected to the pressure of gravity from the upper layer, making it difficult for the solution accumulated between the seeds to drain quickly under its own weight. This slows down the separation process and affects the overall processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a seed sterilization device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A seed sterilization device includes a soaking tank, with an inlet pipe and a drain pipe respectively provided on the top and bottom of the soaking tank, and further includes: The lid is placed on the top surface of the soaking tank; A net basket is placed inside the soaking tank; The air blowing assembly is detachably fixed to the basket. The air blowing assembly includes a hollow vertical tube that is rotatably connected to the bucket lid. Multiple hollow horizontal tubes are connected to the outer wall of the hollow vertical tube, and multiple air outlets are opened on the surface of the hollow horizontal tubes. An air pump is installed on the top surface of the bucket lid. The air pump is connected to an air delivery pipe, the end of which is rotatably connected to the top of the hollow vertical pipe.

[0005] Furthermore, the outer wall of the hollow vertical pipe is fitted with a fixing ring, and the outer wall of the fixing ring is fixedly connected with multiple strip plates at equal angles, with buckles installed on the top surface of each strip plate.

[0006] Furthermore, the inner wall of the basket is fixedly connected with multiple snap-fit ​​plates at equal angles, and the top surface of the snap-fit ​​plates has snap-fit ​​grooves that engage with the snap-fit ​​buckles.

[0007] Furthermore, a geared motor is fixedly connected to the top surface of the bucket lid, and the motor shaft of the geared motor is connected to a gear drive.

[0008] Furthermore, a gear ring is fixedly fitted onto the outer wall of the hollow vertical tube, and the gear ring meshes with a gear for transmission.

[0009] Furthermore, the outer wall of the basket is fixedly connected to multiple support frames at equal angles, and the inner top surface of each support frame is rotatably connected to a roller.

[0010] Furthermore, the inner wall of the soaking tank is fixedly connected to an annular support plate, and the top surface of the annular support plate has an annular groove that cooperates with the roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-4 In this embodiment of the present invention, a seed sterilization device includes a soaking tank 100 for holding a solution of chemicals. An inlet pipe 110 and a drain pipe 120 are respectively provided on the top and bottom of the soaking tank 100. A valve is installed on the drain pipe 120. The device also includes a lid 200, a mesh basket 300, an air blowing assembly 400, and an air pump 500. The lid 200 is detachably and closably located at the opening on the top surface of the soaking tank 100. The mesh basket 300 is located inside the soaking tank 100 and is used to hold seeds. The air blowing assembly 400 is detachably fixed to the mesh basket 300. The top of the air blowing assembly 400 passes through… The hollow vertical tube 410 is rotatably connected to the barrel lid 200 via bearings and a rotating seal. The outer wall of the hollow vertical tube 410 is radially connected to multiple hollow horizontal tubes 420. Multiple tiny air outlets are opened on the surface of the hollow horizontal tubes 420. The air pump 500 is installed on the top surface of the barrel lid 200. The air outlet of the air pump 500 is connected to an air delivery pipe 510. The end of the air delivery pipe 510 is rotatably connected to the top of the hollow vertical tube 410 via a rotary joint. The device also includes a controller, which is electrically connected to the air pump 500 and the geared motor 600 to control the rotation and air delivery of the air blowing assembly 400.

[0017] Specifically, rice seeds are placed inside a net basket 300, burying the air blowing component 400. The net basket 300 is then sent into a soaking tank 100, and liquid medicine is injected into the soaking tank 100 through the liquid inlet pipe 110 until the seeds are completely submerged for soaking and sterilization. After soaking, the liquid medicine is discharged through the drain pipe 120, and the air pump 500 is started. Compressed air is blown out through the air outlets on multiple hollow horizontal pipes 420, breaking the capillary action and water film between the seed layers. At the same time, the air blowing component 400 is controlled to drive the net basket 300 to rotate. The centrifugal force generated by the rotation throws the liquid medicine between the seeds outward, which, together with the airflow, accelerates the discharge speed of the liquid medicine and solves the problem of low efficiency of traditional static draining.

[0018] like Figure 2 As shown, in this embodiment, a geared motor 600 is fixedly connected to the top surface of the bucket lid 200, and a gear 610 is driven to the motor shaft of the geared motor 600. A gear ring 450 is fixedly fitted to the outer wall of the hollow vertical tube 410, and the gear ring 450 meshes with the gear 610 for transmission. A protective cover is provided on the outside of the gear ring 450 and the gear 610 at the top surface of the bucket lid 200.

[0019] In this embodiment, during use, the lid 200 is opened, the net basket 300 is removed from the soaking tank 100, and rice seeds are poured into the net basket 300 until the seeds cover the hollow horizontal tube 420 on the air blowing assembly 400. The lid 200 is then closed, and the net basket 300 containing the seeds is placed back into the soaking tank 100. Liquid solution is injected through the inlet pipe 110 until the liquid level completely covers the seeds. The seeds are then allowed to soak. After soaking, the valve of the drain pipe 120 is opened to drain the liquid solution from the soaking tank 100. Simultaneously, the geared motor 600 and the air pump 500 are started. The motor shaft of the geared motor 600 is driven by the gear 610, which meshes with the gear ring 450, thereby driving the entire air blowing assembly 400 and its components. The fixed net basket 300 rotates synchronously. At the same time, the compressed air generated by the air pump 500 enters the hollow vertical pipe 410 through the air supply pipe 510, and then enters multiple hollow horizontal pipes 420 through the hollow vertical pipe 410. Finally, it is sprayed out from each air outlet, increasing the pore connectivity between the seeds and creating a smooth channel for the discharge of the liquid. This accelerates the discharge speed of the liquid from the seed pores. When the net basket 300 rotates, the centrifugal force throws the liquid in the seed gaps toward the side wall of the net basket 300, passes through the water-permeable holes on the net basket 300, and enters the soaking tank 100 for discharge, accelerating the discharge speed of the liquid. After the discharge is completed, the geared motor 600 and the air pump 500 are turned off, and the tank lid 200 is opened to remove the net basket 300 and the seeds.

[0020] like Figure 2-3 As shown, in this embodiment, a fixing ring 430 is fixedly sleeved on the outer wall of the hollow vertical tube 410, and multiple strip plates 440 are fixedly connected at equal angles on the outer wall of the fixing ring 430. Each strip plate 440 has a buckle 441 installed on its top surface. Multiple snap-fit ​​plates 330 are fixedly connected at equal angles on the inner wall of the basket 300. The top surface of the snap-fit ​​plate 330 has a snap-fit ​​groove that engages with the buckle 441.

[0021] In practice, during installation, the operator places the air blowing assembly 400 into the center of the basket 300. The inner bottom surface of the basket 300 has a groove that contacts the bottom end of the hollow vertical tube 410. After the hollow vertical tube 410 is fully inserted into the groove, the strip plate 440 is located below the snap-fit ​​plate 330. The net basket 300 and the air blowing assembly 400 are rotated relative to each other, so that the strip plate 440 moves to the bottom surface of the corresponding snap-fit ​​plate 330 and the buckle 441 is pressed down until the buckle 441 on the top surface of the strip plate 440 is aligned with the snap-fit ​​groove on the snap-fit ​​plate 330. After releasing the buckle 441, the buckle 441 is locked with the snap-fit ​​groove on the snap-fit ​​plate 330, realizing the quick connection and separation of the air blowing assembly 400 and the basket 300. This ensures that the two can rotate synchronously during operation and makes it easy to separate them when filling seeds or cleaning and maintenance, improving the convenience of use.

[0022] like Figure 3-4 As shown, in this embodiment, multiple support frames 310 are fixedly connected to the outer wall of the basket 300 at equal angles. Rollers 320 are rotatably connected to the inner top surface of each of the multiple support frames 310. An annular support plate 130 is fixedly connected to the inner wall of the soaking tank 100. An annular groove 131 is opened on the top surface of the annular support plate 130, and the annular groove 131 cooperates with the rollers 320.

[0023] In practice, when the basket 300 is placed into the soaking tub 100, the inner top surface of the support frame 310 fixed to the outer wall of the basket 300 will be in contact with the top surface of the annular support plate 130, limiting and supporting the position of the basket 300. At this time, the roller 320 on the support frame 310 falls into the annular groove 131 on the top surface of the annular support plate 130. When the air blowing assembly 400 drives the basket 300 to rotate, the roller 320 rolls in the annular groove 131, providing relatively stable and reliable radial support for the basket 300, effectively preventing the basket 300 from shaking and swaying during rotation, and ensuring the smoothness of operation.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
