The work of the servo motor drives the turntable to rotate, thereby driving the push plate to push the liquid inside the water tank, and the effect of cleaning the corn after spraying by the nozzle is avoided, so as to avoid the situation that dust and impurities remain due to lack of cleaning, which is beneficial to improve the neatness of the corn and avoid the waste of corn resources. However, in actual use, when cleaning the corn before vacuum packaging, liquid is sprayed out by the nozzle for cleaning, and the corn is transported by a conveyor belt. When the corn is transported on the conveyor belt, one side of the corn is always in contact with the conveyor belt, and only the upper part of the corn can be cleaned, and the cleaning effect of the corn cannot be guaranteed. Moreover, the corn is cleaned by liquid, and the drying of the corn is only achieved by the rotation of the fan blades. The corn cannot be guaranteed to be completely dried after cleaning, which will affect the storage effect of the vacuum packaging of the corn later, and there are certain use defects.

[0004] Therefore, we propose a corn vacuum packaging device with a cleaning structure to solve the above-mentioned problems. Summary of the invention

[0017] Preferably, a hollow tube is fixedly installed at the bottom of the movable frame, and a plurality of air outlet pipes are symmetrically opened below the hollow tube, and a connecting tube is connected to one side of the hollow tube. At the same time, a through groove is opened above one side of the fixed frame, and the end of the connecting tube away from the hollow tube is connected to the cylinder.

[0024] By adopting the above technical solution, it is possible to prevent the soft bristles from bringing dust back to the middle of the conveyor belt during movement.

[0025] Compared with the prior art, the invention has the following beneficial effects: the corn vacuum packaging device with a cleaning structure is provided with a cleaning component on one side of the top of the workbench, so that dust on the corn during transportation or storage can be cleaned by blowing air, thereby avoiding the difficulty of subsequent drying and affecting the vacuum packaging, and the corn can be rolled and turned over while being cleaned, thereby fully cleaning the corn, avoiding the existence of cleaning dead corners and avoiding affecting the cleaning effect;

[0026] 1. When vacuum packaging corn, place the corn on the conveyor belt, start the driving motor to drive the roller shaft to rotate, so that the conveyor belt rotates to transport the corn. When the roller shaft on one side rotates, it drives the first pulley to rotate. After the first pulley rotates, the second pulley can be driven to rotate through the belt, so that the rotating shaft rotates on the mounting frame, and then the engagement of the first bevel gear and the second bevel gear drives the rotating rod to rotate on the positioning frame, so as to drive the turntable to rotate. After the turntable rotates, the connecting rod can be pulled to move, and the movement of the connecting rod can drive the movable rod to slide on the fixed sleeve and the cylinder body. The rotation of the turntable allows the movable rod to move back and forth. Check valves are arranged inside the air inlet pipe and several groups of air outlet pipes. When the movable rod drives the piston to move backward in the cylinder body, the check valve inside the air inlet pipe remains closed, so that the piston moves to blow the air inside the cylinder body through the connecting pipe to the outside. The one-way valve inside the air outlet pipe is opened, so that air can be ejected through the air outlet pipe. When the air is ejected through the air outlet pipe, the cross-sectional area of ​​the flow is reduced, so that the flow rate of the air can be accelerated, and the transported corn can be cleaned by the air flow, and the dust on the surface of the corn can be blown off. When the movable rod drives the piston to move forward, the one-way valve inside the air outlet pipe is closed, and the one-way valve inside the air inlet pipe is opened, so that the cylinder can be inflated. When the movable rod reciprocates, the movable frame can be driven to reciprocate by the fixed rod, so that the hollow tube reciprocates, which can expand the blowing range and improve the cleaning effect of the corn, so that the transmission of the corn can be cleaned by the air flow, and after cleaning, it is moved to the inside of the vacuum packaging box through the conveyor belt for vacuum packaging, so that the cleaning of the corn is achieved by the air flow, avoiding the subsequent inability to effectively dry the corn.

[0027] 2. The movable frame can drive the two movable plates to move back and forth when it moves back and forth. The movable frame slides on the positioning rod to support and limit the position when it moves. The two movable plates can continuously move the corn on the conveyor belt to roll during the reciprocating movement. The corn can be cleaned by air flow while rolling, avoiding dead corners for cleaning the corn. Several groups of air outlet pipes are arranged obliquely. The air outlet pipes blow the dust down while allowing the dust to pass between the movable plate and the conveyor belt, avoiding dust accumulation in the middle of the conveyor belt and affecting the subsequent cleaning effect.

[0028] 3. The two movable plates can drive the two moving rods to move back and forth during the reciprocating movement. When the two movable plates move forward, one moving rod drives the sliding rod to slide on the sliding sleeve. Since the sliding rod and the sliding sleeve are both inclined, the sliding rod can be lowered during the movement, and then one moving rod can be lowered when it moves. During the movement, the moving rod drives the limiting sleeve to slide on the limiting rod for limiting, so that the soft bristles on the moving rod can fit tightly with the conveyor belt, and the dust on the conveyor belt can be cleaned by the soft bristles. The moving rod on the other side can rise under the action of the sliding rod and the sliding sleeve to avoid the soft bristles on the other side from fitting tightly with the conveyor belt and avoiding bringing the dust on the conveyor belt to the middle of the conveyor belt, so that the dust on the conveyor belt can be cleaned while avoiding bringing the dust into the middle of the conveyor belt when the moving rod is reset, thereby avoiding affecting the cleaning effect of the conveyor belt and improving practicality.

When the roller shaft 102 on one side rotates, it drives the first pulley 202 to rotate. After the first pulley 202 rotates, the second pulley 205 can be driven to rotate through the belt, so that the rotating shaft 204 rotates on the mounting frame 203, and then the rotating rod 207 is driven to rotate on the positioning frame 206 through the engagement of the first bevel gear 208 and the second bevel gear 209.
