In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.

[0047] In view of the defects of the prior art, the utility model provides a cyperus esculentus cleaning and impurity removing device to clean cyperus esculentus and remove grass clippings, grass roots, silt, stones and other impurities. Figures 1-6 As shown in the figure, the cyperus esculentus cleaning and impurity removing device comprises a tank body 1, a rotary drive 2, a stirring paddle, a first impurity removing assembly, a second impurity removing assembly and a collection box 6.

[0048] The top of the tank body 1 is provided with a water inlet 11 and a feed inlet 12, the water inlet 11 is used to add cleaning water to the inside of the tank body 1, and the feed inlet 12 is used to add cyperus esculentus to be cleaned to the tank body. The bottom center of the tank body 1 is provided with a first discharge port 13, which is used to discharge silt, stones and other easily sinking impurities. The sidewall of the tank body 1 is provided with a second discharge port 14 and a discharge port 15, the second discharge port 14 is located near the top of the tank body 1, which is used for grass clippings and other impurities that can float on the surface of the cleaning water, and the discharge port 15 is located near the bottom of the tank body 1, which is used for the discharge of cleaned cyperus esculentus.

[0049] The stirring paddle is installed in the tank body 1 through the rotary drive 2, and the axis of the stirring paddle coincides with the axis of the tank body 1. The stirring paddle rotates under the drive of the rotary drive 2, and the rotating speed can be adjusted according to the requirement. In the rotating process of the stirring paddle, the cyperus esculentus to be cleaned is added to the tank body 1, and the cyperus esculentus is suspended and rotated in the cleaning water by the rotation of the stirring paddle, so as to clean the cyperus esculentus.

[0050] AsFigures 1-3 As shown in the figure, the first impurity removal assembly includes a collecting rod 41 fixedly combined with the stirring paddle, a scraping blade 42 fixedly combined with the collecting rod 41 near the side of the top of the tank body 1, and a discharge member 43 fixedly combined with the inner wall of the tank body 1 and the second discharge outlet 14. The side edge of the scraping blade 42 away from the collecting rod 41 is higher than the bottom edge of the discharge member 43. When the tank body 1 is filled with cleaning water for cleaning the cyperus esculentus, Figure 1 The middle dotted line represents the water level, and the bottom edge of the discharge member 43 is higher than the water level of the cleaning water. The collecting rod 41 drives the scraping blade 42 to rotate with the rotation of the stirring paddle. The scraping blade 42 can collect the impurities such as grass clippings floating on the water surface together. When it rotates to the position in contact with the discharge member 43, the impurities are discharged out of the tank body 1 along the second discharge outlet 14 under the water flow.

[0051] As shown in the figure, Figure 1 and Figure 4 The second impurity removal assembly includes a separation net 51 arranged in the tank body 1, a driver 52, and a driving rod 53 fixedly combined with the output end of the driver 52. The other end of the driving rod 53 is fixedly combined with the center of the separation net 51 through the side wall of the tank body 1. The driving rod 53 can drive the separation net 51 to rotate in the tank body 1 under the drive of the driver 52.

[0052] The separation net 51 rotates with the driving rod 53, and includes an unfolded state and a side-folded state in the tank body 1. When the separation net 51 is in the unfolded state, as shown in the figure, Figure 1 and Figure 5 The separation net 51 is located between the stirring paddle and the bottom of the tank body 1, and divides the tank body 1 into two parts; when the separation net 51 is in the side-folded state, as shown in the figure, Figure 6 The separation net 51 is vertically arranged in the tank body 1, and is curled to tightly adhere to the inner wall of the tank body 1, and at this time the inside of the tank body 1 is unobstructed.

[0053] When the separation net is in the unfolded state, the driving rod 53 is located below the separation net 51, the discharge outlet 15 is located above the upper surface of the separation net 51, and the separation net 51 and the radial cross section of the tank body 1 are arranged at an angle, and at this time the lowest point of the separation net 51 corresponds to the position of the discharge outlet 15, so that the cleaned cyperus esculentus falling on the separation net 51 can automatically enter the discharge outlet 15.

[0054] The separation net 51 includes a circular ring-shaped outer frame 511 and a filter plate 512 fixedly combined in the circular ring-shaped net frame 511. The filter plate is made of elastic material, and the outer frame 511 is made of relatively hard elastic material, so that the separation net 51 can automatically adjust its shape with the change of position when it is converted between the unfolded state and the side-folded state, avoiding brittle deformation and damage of the separation net 51, and at the same time maintaining its own shape in the unfolded state and the side-folded state.

[0055] The collecting box 6 and the discharge port 15 are communicated, and a valve 150 is arranged at the discharge port 15. During the cleaning operation, the discharge port 15 and the inside of the tank body 1 are not communicated. When the cleaning of the Cyperus esculentus is completed and the discharge is performed, the valve is opened, so that the cleaned Cyperus esculentus enters the collecting box.

[0056] In a specific embodiment, as shown in the figure, the discharge port 15 and the driver 52 are respectively located on two opposite sides of the central axis of the tank body 1. When the separation net 51 is in the unfolded state, the center of the separation net 51 is located on the central axis of the tank body 1, and the angle α between the radial section of the separation net 51 and the tank body 1 is 5-15°. Specifically, the separation net 51 is arranged to be inclined downward from the side close to the driver 52 to the side close to the discharge port 15, so that the Cyperus esculentus on the separation net 51 can automatically enter the discharge port 15 under the action of gravity and water flow. Figure 1 In an embodiment, the driving rod 53 comprises a first rod part 531 and a second rod part 532 arranged perpendicularly to each other. The first rod part 531 is arranged parallel to the horizontal plane, one end of which is fixedly combined with the output end of the driver 52, and the other end is fixedly combined with the second rod part 532.

[0057] The second rod part 532 is fixedly combined with the separation net 51 at the end away from the first rod part 531. When the second rod part 532 is rotated to the position perpendicular to the horizontal plane, the separation net 51 is in the unfolded state. In the unfolded state of the separation net 51, the driving rod 53 is rotated by 90° clockwise or counterclockwise, and the separation net 51 is changed to the side-retracted state. The combined surface of the second rod part 532 and the separation net 51 is a bevel, and the inclination of the bevel is 5-15°, so that when the separation net 51 is in the unfolded state, the radial section of the separation net 51 and the tank body 1 can be arranged at an angle, facilitating the automatic discharge of the Cyperus esculentus.

[0058] In a specific embodiment, the combined part of the first rod part 531 and the second rod part 532 coincides with the central axis of the tank body 1, and the length of the second rod part 532 is equal to the inner diameter of the tank body 1, so that when the separation net 51 is in the side-retracted state, the separation net 51 can tightly adhere to the inner wall of the tank body 1. Since the separation net 51 is made of elastic material, when the separation net 51 is in the side-retracted state, the surface opposite to the connecting surface of the separation net 51 and the driving rod 53 can tightly adhere to the inner wall of the tank body 1 according to the curvature of the inner wall of the tank body 1.

[0059]

[0060] ​In one embodiment, the inner wall of the tank body 1 is provided with a groove track 16, and the outer frame of the separating net 51 is fitted in the groove track 16. The separating net 51 moves along the groove track 16 to switch between the expanded state and the side-retracted state with the rotation of the driving rod 53. When the separating net 51 is in the expanded state, the outer frame of the separating net 51 is fitted in the corresponding position of the groove track 16 to prevent the chufa from entering the first discharge outlet 13 at the bottom of the tank body 1 during the cleaning process. When the separating net 51 is in the side-retracted state, the separating net 51 is entirely fitted in the groove track 16 to retract the separating net 51.

[0061] Further, as shown in Figure 1 , the bottom 17 of the tank body 1 is designed as a spherical bottom with a radius equal to that of the separating net 51. The spherical bottom can make the impurities such as stones and sand more easily enter the first discharge outlet 13, and can sweep the impurities at the bottom of the inner wall of the tank body 1 into the first discharge outlet 13 with the rotation of the separating net 51. Specifically, the bottom 17 of the tank body 1 is detachably connected to the tank body 1 through a flange to facilitate the cleaning or replacement of the separating net 51.

[0062] In one specific embodiment, as shown in Figures 2-3 , the length of the discharge member 43 is less than the inner diameter of the tank body 1. The discharge member 43 is in an L-shaped structure, including a first structure part 431 and a second structure part 432 arranged perpendicular to each other, and the first structure part 431 is arranged in the radial direction of the tank body 1. The first structure part 431 is arranged parallel to the horizontal plane, and the second structure part 432 is combined and fixed to one long side of the first structure part 431 and is located on the upper surface of the first structure part 431. The bottom surface of the first structure part 431, i.e. the bottom surface of the discharge member 43, should be controlled below the water surface when the cleaning water is injected into the tank body 1.

[0063] In one specific embodiment, the collecting rod 41 is in abutment with the inner wall of the tank body 1 away from the end of the stirring paddle, and the collecting rod is arranged in the radial direction of the stirring paddle. The collecting rod 41 is located below the first structure part 431, and the scraper 42 is at least partially located above the first structure part 431, and the upper edge of the scraper 42 does not exceed the upper edge of the second structure part 432. When the collecting rod 41 rotates with the stirring paddle, the scraper will collect the floating debris such as grass clippings, and due to the action of centrifugal force, the debris is generally accumulated on the side edge of the scraper 42 close to the inner wall of the tank body 1, as shown in Figure 3 , when the scraper 42 contacts the first structure part 431, the debris will be left on the first structure part 431, and then enter the second discharge outlet 14 with the water flow.

[0064] In one embodiment, the blade 42 is made of elastic material, and the thickness of the blade 42 gradually decreases away from the end of the collecting rod 41. The bottom of the contact side of the first structure part 431 is processed as a bevel. Since the blade 42 is made of elastic material, when the blade rotates to the discharge member 43, as shown in Figure 3 the blade 42 can smoothly pass through the block of the first structure part 431 by elastic deformation, while the impurities collected by the blade 42 are blocked by the first structure part 431 and enter the second discharge outlet 14 with the water flow.

[0065] In one embodiment, the side wall of the tank body 1 is further provided with an observation window (not shown in the figure), through which the water level and the cleaning state of the chufa in the tank body 1 can be observed.

[0066] In one embodiment, the cleaning and impurity removing device further comprises a clean water circulating assembly 7, which comprises a first filter screen 71, a second filter screen 72, an activated carbon layer 73 and a clean water tank layer 74 stacked in sequence from top to bottom. The mesh number of the first filter screen 71 is smaller than that of the second filter screen 72. Through the layer-by-layer filtration of the first filter screen 71, the second filter screen 72, the activated carbon layer 73 and the clean water tank layer 74, impurities are completely removed.

[0067] The first discharge outlet 13 is connected to the inlet of the clean water circulating assembly 7 through a first discharge pipe 81, the second discharge outlet 14 is connected to the inlet of the clean water circulating assembly 7 through a second discharge pipe 82, and the collecting tank 6 is connected to the inlet of the clean water circulating assembly 7 through a third discharge pipe 83. A gate 130 is provided at the first discharge outlet 13. The gate 130 is in a closed state during cleaning. When it is necessary to discharge impurities such as mud and stones, the gate 130 is opened to allow the impurities to enter the first discharge pipe 81.

[0068] The water outlet of the clean water circulating assembly 7 is connected to the water inlet 11 of the tank body 1 through a backwater pipe 84. The backwater pipe 84 is provided with a circulating pump 85. The waste water discharged through the first discharge outlet 13, the second discharge outlet 14 and the collecting tank 6 is filtered through the clean water circulating assembly 7 and then pumped into the tank body 1 through the circulating pump 85 to realize recycling.
