DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] like Figure 1-Figure 15 As shown, a seed pretreatment device according to an embodiment of the present application includes a tank body 1, and the inner bottom of the tank body 1 is arranged in a stepped shape.

[0040] Specifically, a seed pretreatment device according to an embodiment of the present application further includes a liquid circulation mechanism 2 , which is coaxially arranged on the tank body 1 .

[0041] like Figure 3 As shown, in a specific embodiment of the present application, the liquid circulation mechanism 2 includes a guide tube 21 sealed and plugged into the tank body 1. It should be noted that the height design of the upper end surface of the guide tube 21 needs to meet the liquid level required for soaking seeds.

[0042] Among them, one end of the guide tube 21 located in the tank body 1 is sleeved with a top filter component 22 for intercepting seeds in the liquid entering the guide tube 21 to a certain extent.

[0043] A plurality of spoilers 23 are arranged on the bottom side of the top filter assembly 22, and the plurality of spoilers 23 are evenly distributed around the outer periphery of the flow guide pipe 21. Figure 3 As shown, the provision of the spoiler 23 can reduce the degree of turbulence of the liquid, and prevent the liquid flow entering the top filter assembly 22 from shaking too much, thereby affecting the interception capability of the top filter assembly 22 for seeds.

[0044] One end of the guide pipe 21 extending out of the tank body 1 is connected to a water outlet box 24, and the bottom end of the guide pipe 21 is sleeved with a water inlet box 25, which is connected to the tank body 1. Figure 3 As shown, it can be understood that the water inlet box 25 is located between the water outlet box 24 and the tank body 1.

[0045] The water inlet box 25 is connected to one end of the tank body 1 and is rotatably connected to a water inlet nozzle 26. The water inlet nozzle 26 is evenly arranged with a plurality of arc-shaped and radial water outlet channels in the circumference. It should be noted that in the specific embodiment of the present application, the flow direction in the water inlet nozzle 26 is the direction from the water inlet box 25 to the bottom of the tank body 1, and the arc-shaped and radial water outlet channels inside the water inlet nozzle 26 will drive the water inlet nozzle 26 to rotate when the liquid passes through the water inlet nozzle 26. It can be further understood that liquid is first supplied to the tank body 1 from the inner bottom of the tank body 1. Under the action of the circulation of the liquid, the seeds in the tank body 1 (in the specific embodiment of the present application, it is preferred to describe the seeds as submerged seeds) will tumble under the action of the liquid flow, which can promote the soaking effect of the seeds and avoid the accumulation of seeds inside the tank body 1, causing the seeds to accumulate. Some seeds are not in full contact with the liquid medicine, and at the same time, driven by the liquid flow, the water inlet nozzle 26 will supply liquid into the tank body 1 while rotating at the bottom of the tank body 1, so that the liquid output from the water inlet nozzle 26 will rotate at the bottom of the tank body 1. It can be understood that under the action of the continuous circulation of the liquid flow, the liquid medicine in the tank body 1 will rotate in the same direction as the water inlet nozzle 26, which will further promote the contact between the seeds and the liquid medicine in the tank body 1. At the same time, the seeds will separate due to the rolling and influence of the liquid flow rotation, and invalid seeds and light debris in the seeds will float up, causing the seeds in the tank body 1 to be stratified during the soaking process. Normal seeds are mostly located in the lower layer of the liquid medicine, and light debris and invalid seeds are mostly located in the upper layer of the liquid medicine.

[0046] Specifically, a water pump (not shown in the figure) is connected between the water inlet tank 25 and the water outlet tank 24. The liquid discharged from the water outlet tank 24 is transported to the water inlet tank 25 by the water pump, and then flows back to the bottom of the tank body 1 from the water inlet tank 25, and finally flows from the top to the water outlet tank 24 by the guide pipe 21, so as to form a liquid circuit. In this way, it can be understood that the invalid seeds and light impurities carried by the upper layer of the medicine liquid in the tank body 1 will follow the liquid flow into the top filter component 22, and finally enter from the upper end face of the guide pipe 21, so as to remove the invalid seeds and debris from the seeds soaked in the tank body 1.

[0047] It should be noted that the top filter assembly 22 adopts an annular multi-layer arrangement, and the height of the liquid flow in the top filter assembly 22 gradually decreases from the outer layer to the inner layer, and the height of the fluid flow in the inner layer of the top filter assembly 22 is greater than the height of the fluid flow at the top of the guide tube 21. It can be understood that with this design, the liquid level in the tank body 1 must reach the height corresponding to the outer layer of the top filter assembly 22 before the medicinal liquid can overflow the outer layer and enter the inner layer. As the medicinal liquid enters, the inner sealed liquid level gradually rises until it is higher than the height corresponding to the guide tube 21 before it can enter the guide tube 21. In this way, the top filter assembly 22 is used to allow the medicinal liquid to enter the guide tube 21 by overflow, and has a certain interception effect on the effective seeds in the liquid flow entering the guide tube 21 (the effective seeds will drop under the action of their own gravity and will sink after entering the top filter assembly 22 due to the weakening of the fluid kinetic energy, thereby achieving the interception effect).

[0048] In addition, a seed pretreatment device according to an embodiment of the present application also has the following additional technical features:

[0049] like Figure 1 and Figure 2 As shown, a discharge valve 11 and a support member 12 are provided on the tank body 1. The discharge valve 11 is connected to the bottom end of the tank body 1, and the support member 12 is mounted on the outer wall of the tank body 1. It can be understood that the discharge valve 11 is used to discharge the soaked seeds and the liquid medicine from the tank body 1. The specific installation position and selection are obvious to relevant technical personnel in the field and will not be repeated here.

[0050] like Figure 4-Figure 6 As shown, the two ends of the guide tube 21 are respectively provided with an inner water inlet groove 211 and a threaded end 212 . The inner water inlet groove 211 is evenly arranged at the top of the guide tube 21 circumferentially, and the threaded end 212 is arranged at the bottom of the guide tube 21 .

[0051] It can be understood that, through the design of the inner water inlet groove 211, the top of the guide tube 21 is formed into a fence shape, which further filters the incoming liquid flow, and the design of the threaded end 212 facilitates the installation and disassembly of the water outlet box 24 connected thereto, thereby facilitating the removal of debris and invalid seeds gathered in the water outlet box 24.

[0052] Among them, Figure 3 and Figure 4As shown, the top filter assembly 22 includes: a middle overflow member 221 and an outer overflow member 222. The middle overflow member 221 is fixedly sleeved on the top of the guide tube 21. The cross section of the middle overflow member 221 is U-shaped. The top of the middle overflow member 221 is evenly provided with a middle water inlet groove 223. The height of the bottom end surface of the middle water inlet groove 223 is greater than the height of the bottom end surface of the inner water inlet groove 211. It can be understood that after the liquid level in the middle overflow member 221 rises, it can and can only overflow from the inner water inlet groove 211 into the guide tube 21. , but cannot overflow reversely into the outer overflow piece 222; the outer overflow piece 222 is fixedly sleeved on the outside of the middle overflow piece 221, the cross-section of the outer overflow piece 222 is U-shaped, and the top of the outer overflow piece 222 is evenly circumferentially provided with an outer water inlet groove 224, the height of the bottom end surface of the outer water inlet groove 224 is greater than the height of the bottom end surface of the middle water inlet groove 223, similarly, after the liquid level in the outer overflow piece 222 rises, it can and can only overflow from the middle water inlet groove 223 to the middle overflow piece 221, and cannot overflow reversely into the tank body 1.

[0053] It can be further understood that the cross-sections of the middle overflow member 221 and the outer overflow member 222 are both U-shaped, so that a temporary storage space can be formed inside the two, and the tops of both are provided with fences similar to the top of the guide tube 21, which will have a multiple filtering effect on the passing liquid flow.

[0054] The bottom end surface of the U-shaped outer overflow member 222 is higher than the bottom end surface of the U-shaped middle overflow member 221. It should be noted that in the specific embodiment of the present application, the height of the side wall of the outer overflow member 222 is the same as the height of the side wall of the middle overflow member 221, and the trough body depths of the middle water inlet trough 223 and the outer water inlet trough 224 are the same, so that the net height of the temporarily stored liquid in the two is the same.

[0055] It should be noted that if Figure 3 As shown, in a specific embodiment of the present application, a plurality of spoiler holes 231 are transversely arranged on the spoiler 23. It can be understood that the plurality of transversely arranged spoiler holes 231 will further enhance the flow stabilization effect on the upper layer of the liquid inside the tank body 1, reduce its shaking amplitude, and avoid excessive shaking amplitude of the liquid flow entering the outer overflow member 222, thereby weakening the interception effect of the outer overflow member 222 and the middle overflow member 221 on the effective seeds in the liquid flow.

[0056] like Figure 5 and Figure 6As shown, the water outlet box 24 and the guide pipe 21 are threadedly connected, and a drain pipe 241 is connected to the bottom of the water outlet box 24; the water inlet box 25 is located between the tank body 1 and the water outlet box 24, the water inlet box 25 is connected to the tank body 1, and an inlet pipe 251 is connected to the side wall of the water inlet box 25; the water inlet end of the water pump is connected to the drain pipe 241, and the water outlet end of the water pump is connected to the inlet pipe 251. In this way, it can be understood that under the action of the water pump, the liquid flow will return from the water outlet box 24 to the water inlet box 25 and enter the tank body 1 again. It should be noted that a filtering device is provided in the water outlet box 24 to intercept debris and invalid seeds in the liquid flow output from the tank body 1, and to purify the liquid flow returning to the tank body 1. The circulation of the liquid flow improves the utilization rate of the liquid medicine, provides kinetic energy to the soaked seeds, and enhances the soaking effect.

[0057] like Figure 3 , Figure 7 and Figure 8 As shown, the water inlet nozzle 26 includes: a bottom fixed end 261, an arc-shaped blade 262 and a top fixed end 263. The bottom fixed end 261 is sealed and rotated at the bottom of the tank body 1, as shown in FIG. Figure 3 and Figure 7 As shown, the bottom fixed end 261 is sealed and rotatably sleeved on the guide tube 21, and the upper end surface of the bottom fixed end 261 is in an arc shape that bulges upward, which is used to guide the flow while reducing the resistance to the liquid flow. The bottom fixed end 261 and the water inlet tank 25 are sealed and rotatably connected, so that the bottom fixed end 261 can rotate independently; a plurality of arc-shaped blades 262 are evenly fixed to the upper end surface of the bottom fixed end 261 in the circumferential direction, and the arc-shaped blades 262 are arranged in an arc shape; the top fixed end 263 is fixed to the plurality of arc-shaped blades 262, and the top fixed end 263 is sealed and rotatably sleeved on the guide tube 21, and the top fixed end 263 is fixed to One side of the arc blade 262 is set in an upwardly protruding arc, which guides the liquid flow while reducing the resistance to the liquid flow. The multiple arc blades 262 divide the space between the bottom fixed end 261 and the top fixed end 263 into multiple arc-shaped and radial water outlet channels. The water outlets of the multiple water outlet channels are located on the upper layer of the bottom step of the tank body 1. It can be understood that the liquid flow enters from the bottom fixed end 261, passes through the water outlet channel, and then flows out from the side of the water inlet nozzle 26. In this process, the arc-shaped water outlet channel will generate a rotational force under the action of the liquid flow, causing the water inlet nozzle 26 to rotate at the bottom of the tank body 1.

[0058] It should be noted that in the specific embodiments of the present application, Figure 3 and Fig. 9As shown, the water inlet nozzle 26 is covered with a material blocking assembly 27, and the material blocking assembly 27 includes: a material blocking cover 271, a positioning ring 272 and an elastic member 273. The material blocking cover 271 is sealingly and slidably sleeved on the guide tube 21, and the inner diameter of the material blocking cover 271 is larger than the outer diameter of the water inlet nozzle 26. It can be understood that the material blocking cover 271 will not block the water outlet end of the water inlet nozzle 26; the upper end surface of the material blocking cover 271 is arranged in an inclined shape with the inside higher and the outside lower, so as to avoid residual seeds above it; the positioning ring 272 is fixedly sleeved on the guide tube 21, preferably detachably fixed, such as by threaded connection; the elastic member 273 is sleeved on the guide tube 21, and the two ends of the elastic member 273 are respectively fixed to the inner top of the material blocking cover 271 and the positioning ring 272.

[0059] It should be noted that the elastic member 273 is used to provide a restoring pulling force to the material blocking cover 271 in the direction of the positioning ring 272 .

[0060] It can be understood that in the initial state, under the action of the elastic member 273, the bottom end of the material blocking cover 271 abuts against the bottom of the tank body 1, completely covering the water inlet nozzle 26 therein. When the water pump is started and the liquid flow begins to circulate, liquid flows out from the surrounding side of the water inlet nozzle 26, and the liquid flows converge in the material blocking cover 271, which will increase the pressure inside the material blocking cover 271. When the pressure is greater than the pulling force of the elastic member 273, the deadweight of the material blocking cover 271, and the pressure on the outer side of the material blocking cover 271 inside the tank body 1, the blocking cover 271 is The material cover 271 will drag the elastic member 273 to move upward along the guide tube 21, causing the liquid to flow from the bottom end of the material cover 271 to flow into the tank body 1. When the water pump stops operating, the internal pressure of the material cover 271 decreases, and the material cover 271 will move downward along the guide tube 21 under the pressure exerted by the elastic member 273 and the liquid in the tank body 1 until the water inlet nozzle 26 is completely covered. At this time, the material cover 271 can protect the water outlet channel in the water inlet nozzle 26 to prevent the deposited seeds from causing blockage of the initial channel.

[0061] like Figure 3 , Fig. 9 and Fig.10As shown, a rotary joint 28 is connected between the water inlet nozzle 26 and the water inlet box 25, and the rotary joint 28 enables the water inlet nozzle 26 to rotate in the tank body 1. The rotary joint 28 includes a bottom connecting tube 281, a top connecting tube 282, an inner swivel 283 and an outer swivel 284. The bottom connecting tube 281 is fixedly connected to the lower layer of the bottom step in the tank body 1, and the bottom connecting tube 281 is sealed and sleeved on the guide pipe 21. The bottom connecting tube 281 and the water inlet box 25 are fixedly connected; the top connecting tube 282 is sealed and rotatably connected to the lower layer of the bottom step in the tank body 1, and the top connecting tube 282 is sealed and rotatably sleeved on the guide pipe 21, and the top connecting tube 282 is connected to the water inlet nozzle 26; the inner swivel 283 is respectively connected to the bottom connecting tube 281 and the top connecting tube 2 82 are sealed and rotatably connected, and the bottom connecting tube 281 and the top connecting tube 282 are axially limited by the inner rotating ring 283; the outer rotating ring 284 is sealed and rotatably connected to the bottom connecting tube 281 and the top connecting tube 282 respectively, and the bottom connecting tube 281 and the top connecting tube 282 are axially limited by the outer rotating ring 284; the bottom connecting tube 281 and the top connecting tube 282 are sealed and rotatably connected, it can be seen that the top connecting tube 282 can rotate in the tank body 1, while the bottom connecting tube 281 is in a fixed state, so that the water inlet nozzle 26 will be able to rotate in the tank body 1. It should be noted that the bottom connecting tube 281 and the top connecting tube 282 are both in a double-layer annular setting that is fixedly connected, and a channel for liquid circulation is provided in the axial direction.

[0062] The following describes the use process of a seed pretreatment device according to an embodiment of the present application with reference to the accompanying drawings:

[0063] After the seeds are put in, the tank body 1, the guide pipe 21, the water outlet box 24, and the water inlet box 25 are all filled with liquid medicine. At this time, the height of the liquid medicine is not lower than the height of the outer water inlet groove 224, so as to ensure that the liquid can form a circulation flow path after the water pump is started. The water pump is started to introduce the water in the tank body 1 from the top of the guide pipe 21, and after entering the water outlet box 24, it is transported to the water inlet box 25 by the water pump, and then transported to the material blocking cover 271 through the water inlet nozzle 26. The water inlet nozzle 26 rotates under the action of the liquid flow, and the material blocking cover 271 rises under the action of the gradually converging liquid flow. At this time, the rotating water inlet nozzle 26 transports the liquid flow to the seeds at the bottom of the tank body 1, so that the seeds roll in the tank body 1 and the fluid is transported due to the rotation of the water inlet nozzle 26, so that the liquid medicine in the tank body 1 gradually rotates, thereby further improving the soaking effect of the seeds, and at the same time improving the dispersion effect of the seeds, so that the debris and invalid seeds in it are fully mixed with the liquid flow, and gradually mixed with the seeds in the tank The outer overflow piece 222 and the middle overflow piece 221 as well as the top of the guide tube 21 will gradually enter the interior of the guide tube 21 along with the fluid, and finally converge in the water outlet box 24. Among them, the outer overflow piece 222 and the middle overflow piece 221 as well as the guide tube 21 will intercept the effective seeds passing through the fluid, and reduce the probability of the effective seeds entering the water outlet box 24 along with the fluid. The design of the spoiler 23 will slow down the liquid flow at the liquid surface of the tank body 1, reduce the shaking amplitude of the liquid flow, and enhance the interception effect of the effective seeds. In this way, the invalid seeds and light debris in the seeds can be removed when the seeds are soaked, thereby enhancing the soaking effect and reducing the pretreatment cost. When the equipment is shut down, the material blocking cover 271 can also protect the water outlet end of the water inlet nozzle 26 to prevent the deposited seeds from clogging the water inlet nozzle 26.

[0064] Furthermore, in this seed pretreatment device, when the liquid circulates, debris and invalid seeds may gradually accumulate in the water outlet box 24 as the liquid circulates. If it is only a simple filtration, it will cause blockage inside the water outlet box 24 as the use time increases, affecting the flow rate of the liquid, and then affecting the immersion of the seeds in the tank body 1 and the effect of removing invalid seeds. At the same time, the guide tube 21 is a straight tube. If the liquid flow in it cannot achieve a full tube phenomenon, the liquid flow will produce abnormal noise when passing through the guide tube 21 due to the airflow.

[0065] According to some embodiments of the present application, Fig.11 and Fig.12As shown, a debris handling mechanism 3 is coaxially arranged in the liquid circulation mechanism 2, and the debris handling mechanism 3 includes: a silencer assembly 31, a fixed shaft 32, a plurality of external overflow filters 33 and a plurality of internal overflow filters 34. The silencer assembly 31 is coaxially rotatably arranged in the guide pipe 21. The liquid in the guide pipe 21 is spirally guided by the silencer assembly 31, so that the liquid flows downward in a spiral shape inside the guide pipe 21, thereby avoiding the generation of air when the fluid flows directly downward in the guide pipe 21. noise; the fixed shaft 32 is coaxially fixed to the water outlet box 24 and abuts against the silencer assembly 31, supporting the silencer assembly 31; multiple external overflow filters 33 are dampingly slidably sleeved on the fixed shaft 32; multiple internal overflow filters 34 are dampingly slidably inserted into the water outlet box 24; multiple internal overflow filters 34 and multiple external overflow filters 33 are arranged at intervals, and the external overflow filter 33 is located at the top end of the fixed shaft 32, and the internal overflow filter 34 is located at the bottom end of the fixed shaft 32.

[0066] It can be understood that the design of the damping sliding sleeve facilitates the installation and removal of the external overflow filter 33 and the internal overflow filter 34, as well as the position fixation. Preferably, the damping force design is sufficient to fix the external overflow filter 33 and the internal overflow filter 34 on the fixed shaft 32.

[0067] Among them, the silencer component 31 includes: a rotating shaft 311 and a spiral blade 312, the rotating shaft 311 is coaxially arranged inside the guide tube 21 and abuts against the fixed shaft 32; the spiral blade 312 is fixed to the circumferential side of the rotating shaft 311, and the spiral blade 312 and the inner wall clearance of the guide tube 21 are matched. It can be understood that after the fluid enters the guide tube 21, it flows in the spiral channel formed between the spiral blade 312, the rotating shaft 311 and the guide tube 21, firstly reducing the noise generated when the fluid flows directly in the guide tube 21. At the same time, under the impact of the fluid, the spiral blade 312 and the rotating shaft 311 can be driven to rotate in the guide tube 21. In this way, the impact of the fluid and the rotation of the spiral blade 312 will achieve a flushing and scraping effect on the inside of the guide tube 21, avoiding the blockage of the guide tube 21 by debris and invalid seeds.

[0068] Specifically, Fig.12 As shown, the external overflow filter element 33 includes: a filter plate 331 and an external overflow enclosure 332 , the filter plate 331 is dampingly slidably sleeved on the fixed shaft 32 , and a distance is left between the filter plate 331 and the inner wall of the water outlet box 24 ; the external overflow enclosure 332 is fixedly connected to the side wall of the filter plate 331 .

[0069] The inner overflow filter element 34 includes: a filter ring 341 and an inner overflow enclosure 342. The filter ring 341 is inserted into the water outlet box 24 in a damping sliding manner. A radial spacing is left between the filter ring 341 and the fixed shaft 32. The inner overflow enclosure 342 is fixed to the inner wall of the filter ring 341. An axial spacing is left between the inner overflow enclosure 342 and the filter plate 331. An axial spacing is left between the filter ring 341 and the outer overflow enclosure 332.

[0070] As a result, the outer overflow filter 33 and the inner overflow filter 34 make the fluid form multiple turns in the water outlet box 24, and form a step-by-step filtering effect. It can be understood that when the outer overflow filter 33 at the top is blocked by the filter, the fluid will carry debris and invalid seeds into the inner overflow filter 34 below for filtration. When the inner overflow filter 34 begins to block water due to the filter, the fluid will continue to carry debris and invalid seeds into the outer overflow filter 33 below the air to continue filtering. In this way, the efficiency of the entire water outlet box is improved. The utilization rate of the internal and external overflow filters 33 and the internal overflow filter 34 of 24 is improved, and the filtering capacity of the water outlet box 24 is improved, which fully ensures the cleanliness of the fluid flowing from the water outlet box 24 to the water inlet box 25, makes full use of the liquid medicine, improves the effect of soaking the seeds in the tank body 1 and removing invalid seeds, and at the same time, the water outlet box 24 threadedly connected to the guide pipe 21 is convenient for installation and removal, and the damping sliding sleeve of the multiple external overflow filters 33 and the internal overflow filters 34 therein on the fixed shaft 32 is also convenient for installation and removal, and is easy to clean.

[0071] In the related art, during the use of this seed pretreatment device, the effective seeds and other sediments intercepted in the top filter component 22 may increase with the passage of time. If it is not cleaned in time, the interception effect of the top filter component 22 will be reduced, causing the subsequent incoming fluid to carry the effective seeds and other sediments to flow into the water outlet tank 24, which will burden the purification capacity of the water outlet tank 24.

[0072] According to some embodiments of the present application, Figure 13-Figure 15 As shown, an auxiliary mechanism 4 is arranged in the top filter assembly 22, and the auxiliary mechanism 4 includes: a top bracket 41, an outer guide ring 42, an inner guide ring 43 and a plurality of limit blocks 44, the outer guide ring 42 is sealingly slid in the U-shaped outer overflow piece 222, and is sealingly slidably connected to the outer wall of the U-shaped middle overflow piece 221, and the outer guide ring 42 is fixedly connected to the top bracket 41; the inner guide ring 43 is sealingly slid in the U-shaped middle overflow piece 221, and the inner guide ring 43 is sealingly slidably connected to the outer wall of the guide tube 21, and the inner guide ring 43 is fixedly connected to the top bracket 41; a plurality of limit blocks 44 are circumferentially and evenly fixedly connected to the inner wall of the outer overflow piece 222.

[0073] It can be understood that the top bracket 41 can synchronously drive the outer guide ring 42 and the inner guide ring 43 to perform a certain lifting and lowering movement in the outer overflow member 222 and the middle overflow member 221 .

[0074] Furthermore, the upper end surfaces of the outer guide ring 42 and the inner guide ring 43 are both arranged in an inclined shape with the outer side higher and the inner side lower. Because the side wall height of the outer overflow member 222 is the same as the side wall height of the middle overflow member 221, the middle water inlet trough 223 and the outer water inlet trough 224 have the same trough depth, and the net height of the liquid temporarily stored in the two is the same, Fig.15 As shown, when the outer guide ring 42 and the inner guide ring 43 are displaced to the top, the sediment thereon will slide down along the inclined surface and eventually enter the interior of the guide pipe 21 .

[0075] Therefore, when it is used in practice, an observation window can be set on the top of the tank body 1 or on the water outlet box 24, so as to know whether the sediment intercepted on the upper end surface of the outer guide ring 42 and the inner guide ring 43 needs to be cleaned. When cleaning is needed, the water pump can be paused to stop the flow of liquid, the top cover of the tank body 1 can be opened, the top bracket 41 can be pulled, and moved up and down reciprocatingly, so that the outer guide ring 42 and the inner guide ring 43 connected thereto can be reciprocated and lifted. In this way, the sediment on them will be rushed into the guide pipe 21 under the action of shaking, and fall into the water outlet box 24, and then the external overflow filter 33 and the inner overflow filter 33 in the water outlet box 24 will be cleaned. The overflow filter 34 can be cleaned. This design can maintain the interception effect of the top filter component 22 on effective seeds and other sediments, and can improve the seed removal effect in the tank body 1, and can collect effective seeds from the cleaning process of the external overflow filter 33 and the internal overflow filter 34 (after stopping the pump, the debris on the external overflow filter 33 and the internal overflow filter 34 can be removed, and then the top bracket 41 can be dragged. In this way, the effective seeds can be intercepted on the external overflow filter 33 and the internal overflow filter 34, reducing the difficulty of screening effective seeds from the external overflow filter 33 and the internal overflow filter 34).

[0076] It should be noted that the specific models and specifications of the discharge valve 11, the elastic member 273 and the spiral blade 312 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0077] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
