[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model is equipped with a flap. After the peanuts are washed, the flap is opened, and after the flap is disengaged from the power switch, the power switch powers on the motor, which in turn drives the filter screen to rotate, causing the brush to clean the surface of the filter screen. When the peanuts have finished discharging from the washing chamber, the flap closes under gravity. Pressing the power switch again de-energizes the motor, and the filter screen cleaning stops. The filter screen cleaning time is selected according to the time the flap opens when the peanuts are falling. The more peanuts there are, the more mud and sand they carry, so a longer time is needed to clean the filter screen. Conversely, if the number of peanuts is small, the cleaning time will be shorter, which helps to save energy and improve cleaning efficiency.

[0020] 2. This utility model is equipped with a double-pole switch. When the motor drives the large gear and the toothed gear to rotate continuously, the toothed gear can drive the cylindrical cam to rotate. The cylindrical cam drives the slide rod to move slowly. When the slide rod contacts the double-pole switch, the slide rod disengages from the slide groove of the cylindrical cam under the action of the compression spring. Then, pressing the double-pole switch realizes the forward and reverse rotation of the motor, thereby causing the motor to drive the filter screen to rotate in reverse, so that the brush cleans the filter screen in the opposite direction. When there is a lot of mud and sand, cleaning is carried out in both directions, which helps to improve the cleanliness of the filter screen.

[0021] 3. The second screen of this utility model is provided with several support legs, and the support legs are slidably fitted with sliding sleeves. When the vibration motor is working, it drives the second screen and the peanuts inside the second screen to vibrate. The vibration can make the peanuts change position continuously, so that peanuts that do not meet the specifications can fall out of the second screen. At the same time, the sliding sleeve and the support leg are fixed together by springs, and the springs can reduce the impact on the ground and also reduce noise. Attached Figure Description

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1-6 As shown, this embodiment proposes a peanut washing and screening device, including a housing 1, a washing chamber and a filtering chamber inside the housing 1, a first screen 2 fixed at the bottom of the washing chamber, a filter screen 3 rotatably connected inside the filtering chamber to intercept mud and sand, a motor 5 connected to the filter screen 3, a brush 4 for cleaning the filter screen 3, a discharge port on one side of the washing chamber connected to a flap 6, an energizer switch 7 fixed on the housing 1 to control the operation of the motor 5, the energizer switch 7 cooperating with the flap 6; and a second screen 8 for screening peanuts.

[0033] The aperture of the first screen 2 is larger than the diameter of the mud and sand, but smaller than the diameter of the peanut. The aperture of the filter screen 3 is smaller than the diameter of the mud and sand.

[0034] The flap 6 is limited to the box 1 by a limiting pin, and a sealing strip is provided between the flap 6 and the box 1 to keep the box 1 sealed.

[0035] The bottom of the box 1 is fixed with a drain outlet. After the peanuts are washed, the drain outlet is opened to drain the sewage, which can then be collected or used for secondary washing. At this time, the mud and sand are intercepted by the filter screen 3.

[0036] After the peanuts are washed in the washing chamber, the mud and sand pass through the first screen 2 to the filter screen 3 and are collected by the filter screen 3. At this time, the flap 6 is opened, and the peanuts flow out through the flap 6 under the action of gravity to the second screen 8 for screening.

[0037] After the flap 6 is opened, the flap 6 no longer presses the power switch 7. At this time, the power switch 7 powers on the motor 5, and the motor 5 drives the filter screen 3 to rotate. The filter screen 3 and the brush 4 rotate relative to each other, and the brush 4 cleans the mud and sand on the surface of the filter screen 3.

[0038] The energized switch 7 is a normally closed push-button switch or normally closed push button switch. Its characteristic is that when the button is pressed, the circuit is broken (open circuit), and when the button is released, the circuit automatically closes again (energized). The working principle of this switch is based on the elastic restoring force of the spring. When the button is pressed, the spring is compressed, the contacts separate, and the circuit is broken; when the button is released, the spring returns to its original state, the contacts close again, and the circuit is connected.

[0039] A rotating shaft is fixed to one end of the filter screen 3. A large gear 9 is fixed to one end of the rotating shaft that passes through the housing 1. The motor 5 is directly connected to a power wheel that meshes with the large gear 9. An opening for mud and sand to enter and exit is provided in the axial direction of the filter screen 3. The brush 4 is in contact with the water-facing surface of the filter screen 3.

[0040] Two inclined plates are also fixed inside the filter chamber to facilitate the entry of mud and sand into the filter screen 3.

[0041] A cylindrical cam 10 is rotatably connected to the housing 1, and a slider 11 is slidably connected to the housing 1. A slide rod 12 is slidably connected to the slider 11. The cylindrical cam 10 has a slide groove, and the slider 11 is slidably disposed in the slide groove.

[0042] A sliding shaft is fixedly connected to the housing 1, and the slider 11 is slidably sleeved on the sliding shaft. When the cylindrical cam 10 rotates, the slide rod 12 slides along the inclined groove, which can drive the slide rod 12 to slide.

[0043] A small gear 13 is coaxially fixed to a cylindrical cam 10, and a toothed gear 20 is fixed on a rotating shaft. The toothed gear 20 and the small gear 13 are engaged.

[0044] The toothed gear 20 rotates, causing the cylindrical cam 10 to rotate intermittently, which in turn causes the slide rod 12 to slide.

[0045] The slide bar 12 is connected to the slider 11 via the compression spring 14. The housing 1 is fixedly connected to a double-pole switch 15. The double-pole switch 15 has two toggle positions that can respectively realize the forward and reverse rotation of the motor 5. The double-pole switch 15 cooperates with the slider 11.

[0046] One end of the slide rod 12 is slidably connected to the slide groove on the cylindrical cam 10, and the other end abuts against the housing 1 under the action of the compression spring 14, which helps to keep the end of the slide rod 12 in the slide groove.

[0047] The slide bar 12 slides continuously along the groove of the cylindrical cam 10. After the slide bar 12 slides to the position of the double-pole switch 15, it will press the double-pole switch 15 under the action of the compression spring 14.

[0048] The power switch 7 is electrically connected to the double-pole switch 15.

[0049] When the power switch 7 is pressed, the motor 5 and the double-pole switch 15 can be powered on.

[0050] The double-pole switch 15 has two toggle positions that can respectively realize the forward and reverse rotation of the motor 5. The wiring principle of the double-pole switch 15 is as follows: connect the two wires (A and B) of the motor to the middle contact (common terminal) of the double-pole switch 15. The left and right sets of contacts of the double-pole switch 15 are connected to the positive terminal (VCC) and the negative terminal (GND) of the power supply, respectively. When the double-pole switch 15 is toggled to the left: wire A is connected to VCC and wire B is connected to GND, and the motor rotates forward (or reverse, depending on the motor design). When the double-pole switch 15 is toggled to the right: wire B is connected to VCC and wire A is connected to GND, and the motor rotates in reverse (or forward).

[0051] When there are many peanuts, the flap 6 remains open and the power switch 7 remains energized. At this time, the motor 5 rotates continuously in the forward direction, which in turn drives the filter screen 3 to rotate continuously in the forward direction. The cylindrical cam 10 drives the slide rod 12 to slide continuously until the slide rod 12 contacts the double-pole switch 15. Under the action of the compression spring 14, the slide rod 12 disengages from the slide groove and presses the double-pole switch 15, that is, the double-pole switch 15 is flipped, thereby changing the direction of the motor 5, causing the motor 5 to start to rotate, which in turn drives the filter screen 3 to rotate, so that the brush 4 cleans the filter screen 3 in the reverse direction.

[0052] When there is a lot of mud and sand, some of it can easily get stuck in a certain direction or angle of the filter screen. Cleaning in only one direction can easily cause the mud and sand to get stuck in the same direction as the cleaning direction. Cleaning in both directions can help remove the stuck mud and sand and improve the cleanliness of the filter screen.

[0053] When the number of peanuts is small, the amount of mud and sand they carry will also be reduced accordingly. At this time, the motor rotates for a shorter time, and the slide bar 12 will not contact the double-pole switch 15. At this time, only forward cleaning of the filter screen is performed, which can meet the cleanliness requirements of the filter screen 3.

[0054] The brush 4 is slidably connected to the housing 1. The filter screen 3 is fixed with an end face cam 16. One end of the brush 4 is fixed to the housing 1 by a tension spring 17, and the other end abuts against the end face cam 16.

[0055] The end face of the end cam 16 has protrusions and grooves. When the filter screen 3 rotates, the end face cam 16 drives the brush 4 to slide. At the same time, under the action of the tension spring 17, the brush slides back and forth in the axial direction, which can further improve the cleaning efficiency of the filter screen 3.

[0056] A mud and sand box 18 is placed below the filter screen 3, and a window is provided on the box body 1 for easy access to the mud and sand box 18.

[0057] As the filter screen 3 rotates, the opening of the filter screen 3 rotates downwards, and the mud and sand cleaned by the brush 4 will fall into the mud and sand box 18 for collection. The mud and sand box 18 can be pulled out through the window for cleaning later.

[0058] A vibration motor is fixed on the second screen 8. Several support legs are fixed on the second screen 8. The support legs are slidably fitted with sliding sleeves 19. The sliding sleeves 19 are placed on the ground. The sliding sleeves 19 and the support legs are fixed together by springs.

[0059] Below the second screen 8, there is a waste box 22, and on one side, there is a collection box 23. Peanuts that do not meet the specifications are screened and fall into the waste box 22, while those that meet the specifications will fall into the collection box 23 and be collected.

[0060] When the vibration motor is working, it drives the second screen 8 and the peanuts inside the second screen 8 to vibrate. The vibration can make the peanuts change position continuously, causing peanuts that do not meet the specifications to fall out of the second screen 8. At the same time, the sliding sleeve 19 is fixed to the support leg by a spring. The spring can reduce the impact on the ground and also reduce noise.

[0061] A stirring rod 21 is rotatably connected inside the cleaning chamber, and a motor is directly connected to one end of the stirring rod 21.

[0062] During cleaning, the motor drives the agitator 21 to rotate, and the agitator rod 21 stirs the peanuts in the cleaning chamber, causing the peanuts to tumble and making it easier for the mud and sand to fall off quickly.

[0063] When peanuts are discharged from the flap plate 6, the stirring rod 21 continues to rotate, which can reduce the accumulation of peanuts. When there are only a few peanuts left, the stirring rod 21 can also push the remaining peanuts to move, preventing the flap plate 6 from being stuck by peanuts and unable to reset in time.

[0064] Specific work process:

[0065] S1: Pour the peanuts into the washing chamber inside the box 1, then inject water into the box 1, turn on the motor, and drive the agitator 21 to wash the peanuts in the washing chamber.

[0066] S2: After cleaning to a certain extent, drain the water in the box 1, and then open the limiting pin between the flap 6 and the box 1 to open the flap 6. At this time, the power switch 7 is no longer squeezed, the motor 5 is powered on, and the filter screen 3 is rotated so that the brush cleans the filter screen 3.

[0067] S3: Peanuts fall from the opening at position 6 onto the second screen 8. Under the action of the vibrating motor, the second screen 8 causes the peanuts to vibrate, thus screening the peanuts. Peanuts that do not meet the specifications fall into the waste box 22 below the second screen 8, while peanuts that meet the specifications fall into the collection box 23 and are collected.

[0068] S4: After the peanuts have finished flowing out of the washing chamber, the flap 6 is reset under the action of gravity. Press the power switch 7 again to turn off the power to the motor 5. At this time, open the window on the box 1, pull out the mud and sand box 18, clean the mud and sand inside, and at the same time, the staff observe whether there are any peanuts left in the box 1.

[0069] In S3, when the number of peanuts is small, the motor 5 rotates for a short time. At this time, the slide rod 12 remains in the groove inside the cylindrical cam 10. When the number of peanuts is large, as the motor 5 continues to rotate, the slide rod 12 contacts the double-pole switch 15, and the double-pole switch 15 is activated, causing the motor 5 to reverse and the filter screen 3 and brush 4 to move in the opposite direction, thus achieving multi-angle cleaning.

[0070] In S4, when pulling out the mud and sand box 18, observe the angle of the filter screen 3. If the angle is misaligned, move the filter screen 3 to reset it so that the opening of the filter screen 3 faces upward.

[0071] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
