[0005] In order to improve the efficiency of nut cleaning, the present application provides a high-efficiency and energy-saving nut cleaning device.

[0006] This application provides an efficient and energy-saving nut cleaning device, which adopts the following technical solutions:

[0007] A high-efficiency and energy-saving nut cleaning device includes a frame and a vibrating screen arranged on the frame, a feed hopper and a discharge pipe are respectively provided on the frame at both ends of the vibrating screen, nuts mixed with impurities are moved to the vibrating screen through the feed hopper, and the nuts screened by the vibrating screen are discharged through the discharge pipe, the feed hopper is provided with a blowing fan for blowing air to the nuts in the feed hopper, and the discharge pipe is provided with a spray mechanism for spraying the nuts discharged from the discharge pipe.

[0008] By adopting the above technical solution, when the nuts enter the feed hopper, the blowing fan starts to blow air on the nuts. The blowing fan first blows off the impurities that are easily blown up on the nuts, and then the nuts are moved to the vibrating screen. The vibrating screen filters out the large-density impurities in the nuts. The nuts screened by the vibrating screen are moved to the discharge pipe, and the spray mechanism in the discharge pipe starts to spray the nuts to remove impurities adhering to the nuts, thereby improving the purity of the nuts finally discharged from the discharge pipe, shortening the nut cleaning process, and improving work efficiency.

[0009] Optionally, the spraying mechanism includes:

[0010] A spray pipe, the spray pipe is rotatably arranged on the discharge pipe and is connected to the water source, and a plurality of spray heads are evenly distributed along the axial direction on the spray pipe;

[0011] A rotating motor, wherein the rotating motor is arranged on the discharge pipe and the output shaft is connected to the spray pipe;

[0012] A water collecting assembly is provided on the discharge pipe and is used for collecting water sprayed from the spray pipe.

[0013] By adopting the above technical solution, water flows through the spray pipe through several spray heads to spray the nuts. At the same time, the rotating motor starts to drive the spray pipe to rotate, so that the spray pipe can spray the nuts evenly. After spraying, the water with impurities is collected by the water collection component, thereby completing the uniform spraying of the nuts.

[0014] Optionally, the water collection component includes:

[0015] A water collecting frame, which is arranged on the inner bottom wall of the discharge pipe, and the upper opening of the water collecting frame is open;

[0016] The water filter net is arranged on the water collecting frame, and water holes for only water flow are evenly distributed on the water filter net.

[0017] By adopting the above technical solution, when the spray pipe sprays the nuts, the nuts pass through the water filter and are removed, while the water generated by the spraying and the impurities washed off the nuts enter the water collection frame through the water holes for collection and treatment, thereby completing the collection of the water generated during the spraying.

[0018] Optionally, the frame is provided with a water return mechanism for recycling the water collected in the water collection frame, and the water return mechanism includes:

[0019] A return water tank, the return water tank being arranged on the frame;

[0024] By adopting the above technical solution, the water collected in the water collection frame enters the return water tank through the outlet pipe. The return water tank allows the water with impurities to stand still and uses gravity to allow the impurities to settle naturally. Then the return water pump is started to extract the upper clear water through the return water pipe and guide it back to the spray pipe, thereby completing the water reuse work and reducing the waste of water resources; at the same time, the fine-pore filter screen filters the water entering the return water pipe, thereby ensuring the purity of the water returning to the spray pipe.

[0025] Optionally, the interior of the return water tank is divided into two layers at different heights: a bottom sedimentation layer and an upper liquid extraction layer. The return water pipe is located in the upper liquid extraction layer. The outlet of the outlet pipe is arranged toward the side wall where the return water pipe is connected to the return water tank. The water discharged from the outlet pipe flows along the surface of the fine-pore filter mesh.

[0026] By adopting the above technical solution, the interior of the return water tank is divided into two layers at different heights: a bottom sedimentation layer and an upper liquid extraction layer. The bottom sedimentation layer is used to settle and collect impurities in the water body, while the clear water body in the upper liquid extraction layer can be pumped back to the spray pipe through the return water pipe for reuse; the outlet of the outlet pipe is arranged toward the side wall on the side where the return water pipe and the return water tank are connected, so that the water body can flush the surface of the fine-pore filter mesh when entering the return water tank, reducing the probability of impurities filtered out by the fine-pore filter mesh accumulating on the surface of the fine-pore filter mesh and causing it to be blocked.

Under the action of gravity, the bottom of the waste outlet door is snap-fitted with the snap-in groove to block the waste outlet hole.

[0031] By adopting the above technical solution, when it is necessary to clean the impurities deposited at the bottom of the return water tank, the waste outlet door is removed, the driving assembly is started to drive the cleaning plate to move, and the cleaning plate moves to push the impurities deposited at the bottom of the return water tank. The cleaning plate pushes the impurities out of the waste outlet hole and then moves back to the waste outlet door to block the waste outlet hole, thereby completing the cleaning of the impurities in the return water tank.

[0032] Optionally, the driving component includes:

[0033] A driving screw, the driving screw being rotatably mounted on the return water tank and being threadably connected to the cleaning plate;

[0034] A driving motor is provided on the outer side wall of the return water tank and an output shaft is connected to the driving screw.

[0035] By adopting the above technical solution, the driving motor starts to drive the driving screw to rotate, and the driving screw rotates to drive the cleaning plate to move. The movement of the cleaning plate pushes the impurities back into the water tank, thereby realizing the movement of the cleaning plate by controlling the driving motor.

[0036] Optionally, sealing strips are provided on the sides and bottom of the waste discharge door.

[0037] By adopting the above technical solution, sealing strips are installed on the sides and bottom of the waste outlet door, thereby ensuring the sealing effect of the waste outlet door on the waste outlet hole and reducing the probability of water leakage in the return water tank.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. The blower fan starts to blow air on the nuts, which first blows away impurities that are easily blown up from the nuts. The nuts are then moved to the vibrating screen, which filters out impurities with high specific gravity from the nuts. The nuts that have been screened by the vibrating screen are moved to the discharge pipe, where the spray mechanism starts to spray the nuts to remove impurities adhering to the nuts, thereby improving the purity of the nuts finally discharged from the discharge pipe, shortening the nut sorting process and improving work efficiency.

[0040] 2. When the nuts are sprayed through the spray pipe, the nuts pass through the water filter and are removed, while the water generated by the spraying and the impurities washed off the nuts enter the water collection frame through the water holes for collection and treatment, thus completing the collection of the water generated during the spraying;
