DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example:

[0028] Reference Figure 1-Figure 4 A pea impurity removal device comprises a working box 1, a vibrating screen bucket 2 is connected to the inner wall of the working box 1 through a flexible connector, a feeding pipe is arranged on the working box 1, and is arranged above the opening end of the vibrating screen bucket 2. The flexible connector can be a rubber strip or a vibration spring. A vibration motor is also arranged on the side wall of the vibrating screen bucket 2, and the cross-section of the vibrating screen bucket 2 is U-shaped, with an opening end at the top and a filter net at the bottom, which is used to clean impurities in the peas. The vibrating screen bucket 2 can generate high-frequency vibration through the vibration of the vibration motor, thereby separating and intercepting impurities. A guide net is also arranged below the vibrating screen bucket 2 for guiding and collecting the peas, and a through hole matching the guide net is opened on the working box 1 for moving the peas.

[0029] In addition, an installation box 4 is fixedly connected in the working box 1, and a reciprocating screw 401 is rotatably connected in the installation box 4. The reciprocating screw 401 is driven by a driving machine, which can be a driving motor or an electric motor. A movable block is also threadedly connected to the reciprocating screw 401, and the movable block fits against the inner wall of the installation box 4, and then the negative pressure suction plate 3 is fixedly connected to the movable block.

[0030] When the reciprocating screw rod 401 rotates, the movable block can be displaced on the mounting box 4. A negative pressure suction hole 301 is also provided at the bottom of the negative pressure suction plate 3, and the adsorption end of the negative pressure suction hole 301 faces the vibrating screen bucket 2, so as to adsorb impurities in the vibrating screen bucket 2.

[0031] At the same time, a connecting plate is fixedly connected to the inner wall of the working box 1, a guide cylinder 7 is fixedly connected to the connecting plate, a guide rod 701 is slidably connected to the guide cylinder 7, an injection plate 6 is fixedly connected to the guide rod 701, and an injection hole is opened on the injection plate 6.

[0032] A boosting cylinder 5 is fixedly connected to the inner wall of the working box 1, and a boosting rod 501 is slidably connected to the boosting cylinder 5. A piston is arranged on the boosting rod 501, and the piston fits the inner wall of the boosting cylinder 5. The boosting cylinder 5 is connected to the guide cylinder 7, and a spring is arranged in the boosting cylinder 5, and both ends of the spring are fixedly connected to the boosting cylinder 5 and the piston respectively.

[0033] It needs to be explained that a collecting box 8 is fixedly connected to the top of the working box 1, an intercepting net 801 is arranged in the collecting box 8, and the negative pressure suction plate 3 is connected with the cavity below the intercepting net 801 through a pipeline, and a negative pressure pump is arranged in the collecting box 8, the input end of the negative pressure pump is arranged above the intercepting net 801 through a pipeline, and the output end of the negative pressure pump is fixedly connected to the jet plate 6 through a pipeline. When impurities enter the collecting box 8, the intercepting net 801 can intercept the impurities.

[0034] When it is necessary to adsorb and collect impurities in the vibrating screen bucket 2, the switch of the driving machine can be started to drive the reciprocating screw 401 to rotate, thereby moving the negative pressure suction plate 3 to the opening end of the vibrating screen bucket 2. At this time, the suction end of the negative pressure suction plate 3 can extend above the opening end of the vibrating screen bucket 2.

[0035] During this process, the negative pressure suction plate 3 will contact the boosting rod 501 and move the boosting rod 501, and the boosting rod 501 will compress the internal spring, and then the gas in the boosting cylinder 5 will be transported to the guide cylinder 7. At this time, the gas transported to the guide cylinder 7 will push the guide rod 701 to move outward, and the guide rod 701 will drive the jet plate 6 to move to the bottom of the vibrating screen bucket 2. At this time, the jet end of the jet plate 6 can extend to the unloading end of the vibrating screen bucket 2, that is, below the filter screen.

[0036] At this time, the switch of the negative pressure pump is turned on, and negative pressure is generated in the collecting box 8, so that the negative pressure suction plate 3 can adsorb impurities on the surface of the vibrating screen bucket 2, and the impurities are concentrated in the collecting box 8, thereby reducing the amount of impurity accumulation inside the vibrating screen bucket 2. In this way, the interference of impurities on the screening of the vibrating screen bucket 2 during the vibration screening process can be reduced, thereby improving the screening efficiency.

[0037] In addition, the filter holes of the vibrating screen bucket 2 can be sprayed with air through the jet plate 6 to eject impurities stuck in the holes, which can reduce the frequency and workload of manual cleaning of the filter holes, restore the smoothness of the filter holes on the vibrating screen bucket 2, and improve the impurity removal efficiency.

[0038] In addition, a cleaning plate 9 is slidably connected in the collecting box 8, an extension rod 901 is fixedly connected to the cleaning plate 9, a discharge port is opened on the collecting box 8, a sealing plate 802 is slidably connected to the discharge port, and the sealing plate 802 cooperates with the cleaning plate 9.

[0039] When the impurities are adsorbed into the collecting box 8, the filtered air will be re-delivered to the jet plate 6 through the negative pressure pump to form a circulation effect. After the impurities in the vibrating screen bucket 2 are adsorbed, the switch of the driving machine can be started to reset the negative pressure suction plate 3. At this time, the negative pressure suction plate 3 moves out from above the opening end of the vibrating screen bucket 2, and the spring in the booster cylinder 5 resets to generate negative pressure, so that the gas in the guide cylinder 7 is adsorbed into the booster cylinder 5. At this time, the jet plate 6 is reset, and the jet plate 6 moves out from below the discharge end of the vibrating screen bucket 2.

[0040] By opening the sealing plate 802 and then pulling the extension rod 901, the extension rod 901 drives the cleaning plate 9 to move outward, and then the collected impurities can be pulled out to the outside for centralized collection, thereby improving the convenience of impurity removal of the device.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
