[0036] Further, the wastewater treatment structure further comprises a drain pipe 20 communicating between the cleaning bin 3 and the wastewater tank 8, a base plate 21 is slidably connected to the top of the wastewater tank 8, the base plate 21 is provided with a first drain opening 22 and a second drain opening 23, the inside of the base plate 21 is provided with a slot 24 at the position of the first drain opening 22 and the second drain opening 23, the inside of the base plate 21 is provided with an electric push rod 25 through the cavity, the inside of the base plate 21 is provided with a sealing plate 26 through the sliding connection to block the first drain opening 22 and the second drain opening 23, the output end of the electric push rod 25 is fixedly connected with the sealing plate 26, the top of the filter hole 14 and the inside of the wastewater tank 8 are fixedly connected with a return spring 40, and the top of the return spring 40 is fixedly connected with the bottom of the base plate 21. When filtering, the wastewater enters the filtering process through the first drain opening 22, when it is necessary to start cleaning and dredging, the electric push rod 25 is extended to drive the sealing plate 26 to insert into the slot 24, so that the first drain opening 22 is completely closed, the wastewater is gathered on the top of the base plate 21, and the weight of the wastewater gathered on the base plate 21 is increased to drive the base plate 21 to descend, so as to provide power for the subsequent linkage wall scraping structure and dredging assembly.

[0037] Next, the dredging assembly comprises an inclined chute 27 arranged on the inner wall of the wastewater tank 8, a hollow plate 28 is slidably connected to the inside of the wastewater tank 8 along the inclined chute 27, a first spring 33 is arranged in the inside of the inclined chute 27, a scraper 29 is arranged on the bottom of the hollow plate 28, a hollow cylinder 30 is arranged in the hollow of the hollow plate 28, a second spring 34 is arranged in the inside of the hollow cylinder 30 and a silica gel top block 32 is slidably connected to the inside of the hollow cylinder 30, the bottom of the second spring 34 is fixedly connected with the top of the silica gel top block 32, the dredging assembly further comprises a top plate 35 fixedly connected to the bottom of the filter plate 13, a second baffle 37 rotatably arranged at the middle position of the sealing plate 26 through a rotating shaft 36, the rotating shaft 36 is provided with a torsional spring to facilitate the second baffle 37 to reset after being opened, a discharging inclined plate 48 is fixedly arranged at the bottom of the base plate 21 in the inside of the wastewater tank 8, and the discharging inclined plate 48 is provided with a notch to facilitate water flow, and the end of the discharging inclined plate 48 is arranged at the waste outlet 18, when the base plate 21 closes the first drain opening 22 and gathers wastewater to descend and contact the top of the hollow plate 28, the electric push rod 25 is controlled to retract to open the first drain opening 22, the wastewater on the top of the base plate 21 is discharged to the space between the hollow plate 28 and the filter plate 13 through the first drain opening 22, because the filter hole 14 is blocked by the first baffle 15, the wastewater cannot fall, and then the wastewater drives the hollow plate 28 to slide along the inclined chute 27 and compresses the first spring 33, when the hollow plate 28 moves, the scraper 29 on the bottom contacts the top of the filter plate 13 to scrape the surface impurities; at the same time, the silica gel top block 32 in the hollow cylinder 30 moves to insert into the filter hole 14 to dredge the internal blockage under the action of the second spring 34.

[0038] In addition, the wall scraping structure includes a chute 38 arranged on the inner wall of the chopping tank 9, an annular scraper 39 is slidably connected to the chute 38 inside the chopping tank 9, one end of the first steel cable 12 is connected to the scraper 39 and the other end is fixedly connected to the backing plate 21, the inside of the chute 38 is provided with a third spring 41, and one end of the third spring 41 is fixedly connected to the scraper 39. When the backing plate 21 is lowered due to the accumulation of wastewater in the closed first drainage port 22, the scraper 39 is driven by the first steel cable 12 to slide along the chute 38 on the inner wall of the chopping tank 9. The scraper 39 scrapes the straw residues adhered to the inner wall of the chopping tank 9 during movement, ensuring that there is no residue on the inner wall of the chopping tank 9, and ensuring the subsequent straw chopping efficiency.

[0039] Exemplarily, the inside of the partition plate 2 is provided with an opening and closing structure for the cleaned straw in the cleaning bin 3 to enter the inside of the cooking bin 4. The opening and closing structure includes a third baffle 42 slidably connected to the inside of the partition plate 2, a fourth spring 43 fixedly arranged in the inside of the partition plate 2, a second steel cable 44 connected to one end of the third baffle 42, and the other end of the second steel cable 44 connected to the hollow plate 28. When the wastewater is discharged through the first drainage port 22 and pushes the hollow plate 28 to move along the chute 27, the hollow plate 28 pulls the second steel cable 44, so that the third baffle 42 is retracted into the inside of the partition plate 2 and the fourth spring 43 is compressed. Then the partition plate 2 is opened. Because the wastewater in the cleaning bin 3 has been discharged through the drainage pipe 20 and the first drainage port 22, only the cleaned straw remains. The straw falls into the cooking bin 4 through the opening of the partition plate 2.

[0040] Working principle: the straw enters the inside of the chopping tank 9 from the feed inlet 11, and then the straw in the tank body is chopped by the rotation of the chopping blade 10, and then reaches the inside of the cleaning bin 3 through the discharge port 47. Then the water pump 45 is started to inject the water in the first water tank 6 into the cleaning bin 3 through the pipeline 46. After cleaning, the drainage pipe 20 is opened. The screen arranged on the drainage pipe 20 can block the straw to prevent the straw from entering the drainage pipe 20. The wastewater discharged through the drainage pipe 20 reaches the top of the backing plate 21.

[0041] When the cleaned wastewater is filtered, that is, in the normal state, the output end of the electric push rod 25 is in the retracted state and the long sealing plate 26 moves out of the slot 24, so that the second drainage port 23 in the normal state is opened. Therefore, the wastewater on the top of the backing plate 21 falls to the top of the filter plate 13 through the second drainage port 23, and then the impurities in the wastewater are intercepted and filtered through the filter hole 14. Then the water falls through the filter plate 13 and reaches the inside of the first water tank 6 through the discharge chute 48, thereby storing the filtered wastewater. When the straw is cleaned next time, the water pump 45 is started to re-inject the filtered water into the cleaning bin 3 through the pipeline 46, thereby realizing comprehensive recycling of the wastewater.

[0042] But long-term filtering, the surface of the filter plate 13 will adhere to a layer of impurities, and the filter hole 14 also exists the risk of blockage, for the removal of the filter plate 13 surface impurities filter hole 14 dredging can be completed in the cleaning of straw drainage, as follows:

[0043] The conventional filter state of the baffle 15 and the filter hole 14 is staggered, when the above purpose is needed, the motor 19 with the threaded rod 17 rotates, then through the support block 16 with the first baffle 15 moves, through the first baffle 15 to block the filter hole 14, as shown, then the electric push rod 25 extends with the longer sealing plate 26 moves and inserts into the slot 24, and then closes the second drainage port 23, at this time the pad 21 is in a completely closed state; Figure 9

[0044] The waste water in the cleaning bin 3 is normally discharged to the inside of the waste water tank 8 through the drain pipe 20, but because the pad 21 is closed, at this time the waste water will accumulate on the top of the pad 21 but will not fall down, as the weight of the waste water on the pad 21 increases, the pad 21 slides down and compresses the return spring 40, the pad 21 descends through the first steel cable 12 with the scraper 39 in the crushing tank 9 moves, the scraper 39 moves along the chute 38 and compresses the third spring 41, through the movement of the scraper 39 to scrape off the straw impurities adhering to the inner wall of the crushing tank 9, which is helpful to solve the shortcomings raised in the background art;

[0045] When the bottom of the pad 21 cannot descend to contact the top of the hollow plate 28, at this time the first drainage port 22 is opened by the electric push rod 25, the opening width of the first drainage port 22 is proportional to the length of the output end of the electric push rod 25, after opening, the waste water accumulated on the top of the pad 21 is discharged to the space between the hollow plate 28 and the filter plate 13, because the filter hole 14 is completely blocked by the first baffle 15 at this time, so the water will not fall from the filter plate 13;

[0046] Because of the increase of the waste water on the top of the filter plate 13 and the top of the hollow plate 28, at this time the waste water will push the hollow plate 28 to move along the chute 27 and compress the first spring 33, when the hollow plate 28 moves, the scraper 29 at the bottom of the hollow plate 28 contacts the top of the filter plate 13, then the top of the scraper 29 scrapes off the impurities on the top of the filter plate 13, and by controlling the size of the opening of the first drainage port 22, the waste water flows evenly over the top of the filter plate 13, by controlling the water quantity, the hollow plate 28 can move slowly along the chute 27;

[0047] ​At the same time, the hollow plate 28 moves obliquely downward under the action of water. When the silica gel top block 32 contacts the solid part of the filter plate 13, the second spring 34 is compressed at this time. With the movement of the hollow plate 28 to the position of the filter hole 14, the second spring 34 resets with the silica gel top block 32 inserted into the inside of the filter hole 14, and then the silica gel top block 32 pushes the block-shaped object clogging in the filter hole 14 into the inside of the first baffle 15. Since the silica gel top block 32 has elasticity, with the movement of the hollow plate 28, the previously inserted silica gel top block 32 will bend and pull out, and then be inserted into the next group of filter holes 14 with the movement of the hollow plate 28. The operation is repeated to clean the surface of the filter plate 13 and also to dredge the filter holes 14. The force exerted on the hollow plate 28 by the wastewater is realized throughout the process, and manual cleaning is not required. The automatic cleaning and dredging can be realized, thereby solving the shortcomings in the background art.

[0048] Then, the first baffle 15 is slightly moved by the rotation of the motor 19, and the filter hole 14 is opened by the slight movement of the first baffle 15. However, it is ensured that the first baffle 15 does not disengage from the top plate 35, so as to prevent the impurities in the first baffle 15 from re-entering the wastewater. When the wastewater is discharged from the filter plate 13, the discharge port 18 is closed.

[0049] When the wastewater is discharged, the motor 19 moves the first baffle 15 again and hits the top plate 35. Then, the blocking effect of the top plate 35 makes the rotating shaft 36 and the second baffle 37 rotate, so as to open the first baffle 15. Then, the impurities in the first baffle 15 are discharged from the position opened by the second baffle 37 together with the water in the first baffle 15. The small amount of water discharged will come to the inside of the first water tank 6 through the discharging inclined plate 48, and the discharged impurities will fall into the opened discharge port 18 along the slope of the discharging inclined plate 48, and then be discharged through the discharge port 18, thereby realizing the cleaning and dredging process of the entire filter plate 13.

[0050] Since the cleaned straw needs to come to the inside of the steaming bin 4, the partition plate 2 needs to be opened, at this time, the opening of the partition plate 2 still needs to be completed by the help of the discharged waste water, and the waste water is discharged to the top of the cushion plate 21, at this time, the first drain port 22 is opened, by the above-mentioned operation, at this time, the hollow plate 28 is inclined to move downward to pull the second steel cable 44, at this time, the waste water on the top of the partition plate 2 has been completely discharged, only the cleaned straw, the second steel cable 44 is pulled to retract the third baffle 42 into the inside of the partition plate 2 and compress the fourth spring 43, by the retraction of the third baffle 42, the partition plate 2 is opened, and the side of the partition plate 2 away from the third baffle 42 is designed to be inclined, then the straw on the top of the partition plate 2 falls into the inside of the steaming bin 4 along the inclination and the opened port, the operation of the whole device greatly reduces the manual intervention, the whole is completed by the help of the waste water to complete a series of operations, the device has remarkable creativity in the use of waste water, and the device separates the crushing, cleaning and cooking into separate designs to solve the shortcomings in the background technology.

[0051] The following proposes an alternative, since in actual use, the above-mentioned operations such as the dredging and cleaning of the filter plate 13, the opening of the partition plate 2 are completed by the help of the drainage from the first drain port 22, therefore, the role of the second drain port 23 is rarely used in actual use, the purpose of the design of the second drain port 23 is only to improve the drainage speed when simply filtering, that is, no dredging and cleaning is needed, because the second drain port 23 is designed to have a larger opening, therefore, the second drain port 23 can be deleted and only the first drain port 22 is retained.

[0052] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
