Example 2

As shown in fig. 1-6, on the basis of embodiment 1, the present utility model provides a technical solution: preferably, one side fixedly connected with connecting strip 12 of baffle 4, the part sliding connection that connecting strip 12 was not connected with baffle 4 has fixed slot 13, the inner wall and the connecting strip 12 sliding connection of fixed slot 13, the both sides fixed connection of fixed slot 13 is on the inner wall of fuselage 1, fixed mounting has motor case 9 on the inner wall of fuselage 1, the inside fixed mounting of motor case 9 has the motor, the output of motor passes through shaft coupling fixedly connected with pivot, pivot fixedly connected with rocker 10, the one end that rocker 10 kept away from motor case 9 is articulated through the bull stick has ejector pad 11, the one end that ejector pad 11 kept away from rocker 10 is articulated with connecting strip 12. The fixing groove 13 is provided, so that the connecting bar 12 is restricted to a horizontal line for reciprocating rectilinear motion.

The end of the rotating plate 5 which is not contacted with the material conveying pipe 3 is fixedly connected with a right-angle barb 6, and the barb position of the right-angle barb 6 is slidingly connected with the lower surface of the rotating plate 7. Through setting up right angle barb 6, because of the lower surface of its barb department is oblique landslide form for when the rotor 7 resets, its one end can slide on the landslide and push away right angle barb 6, treat when rotor 7 resets completely, the barb can reset and detain it, like this, when the potato of size less passes through, can not drop.

The inner wall of the cylindrical part of the rotating plate 5 is fixedly provided with a rotating rod, the rotating rod is rotationally connected to the inner wall of the machine body 1 through a bearing, the inner wall of the cylindrical part of the rotating plate 7 is fixedly provided with a rotating roller, and the rotating roller is rotationally connected to the inner wall of the machine body 1 through a bearing. All contact has the torsional spring on the outer wall of commentaries on classics stick and commentaries on classics roller, and the torsional spring then can be when commentaries on classics board 5 and commentaries on classics piece 7 are promoted by the potato, can produce the moment of torsion for the torsional spring produces pulling force, and when commentaries on classics board 5 and commentaries on classics piece 7 do not receive the power, the torsional spring of taking place deformation will drive commentaries on classics board 5 and commentaries on classics piece 7 and reset.

In this embodiment, by arranging the motor case 9, the rocker 10 and the push block 11, the motor in the motor case 9 can drive the rocker 10 to rotate, the rocker 10 can then drive the push block 11 to reciprocate, and the push block 11 can then drive the connecting bar 12 to reciprocate, so as to assist in the screening work of the equipment.

The working principle of the hierarchical screening device with the cleaning structure is specifically described below.

When the potato screening machine is used, as shown in fig. 1-6, potatoes to be screened are placed into the feed inlet 2, at the moment, the potatoes are blocked by the baffle plate 4 and cannot fall, a motor in the motor box 9 is started, the motor drives the rocker 10 to rotate through the rotating shaft, the rocker 10 drives the push block 11 to reciprocate, the push block 11 drives the connecting strip 12 to reciprocate, the connecting strip 12 slides back and forth with the fixed groove 13, the connecting strip 12 drives the upper baffle plate 4 and the lower baffle plate 4 to reciprocate, when the upper baffle plate 4 is driven by the connecting strip 12 to completely leave the conveying pipe 3, only one potato can fall and can be blocked by the lower baffle plate 4, when the lower baffle plate 4 is driven by the connecting strip 12 and completely leave the conveying pipe 3, the potato can fall, and the upper baffle plate 4 can enter the conveying pipe 3 to block the potatoes above the conveying pipe, at this time, the potato which falls off before can move along the conveying pipe 3 to the discharge hole 8, when the potato reaches the rotating plate 5, if the potato is large in size, the potato can touch the rotating plate 5, at this time, the rotating plate 5 can rotate upwards under the collision of the potato, meanwhile, the rotating plate 5 can drive the right-angle barb 6 to lift upwards, the barb part of the potato leaves the rotating plate 7, the rotating plate 7 can not be blocked and can rotate downwards, at this time, the potato can pass through the upper surface of the rotating plate 7, under the action of gravity, thrust is applied to the rotating plate 7, the rotating plate 7 rotates downwards, at the same time, the potato can fall from the rotating plate 7, after falling, the rotating plate 7 can automatically reset and rotate to the original position, at the same time, the rotating plate 5 can drive the right-angle barb 6 to reset to the original position, and because the lower surface of the barb part of the right-angle barb 6 is in a slope shape, when the rotating plate 7 resets, the potato can slide on a sliding slope and push away the barb, returning to the original position, the right-angle barb 6 is reset under the action of the rotating plate 5, so that the rotating piece 7 is buckled. If the potato size is small, it will not touch the rotating plate 5 when it reaches the rotating plate 5, and will follow the path of the conveying pipe 3 until it reaches the discharge opening 8. When the equipment needs cleaning, the atomizing nozzle 14 is rotated to be opposite to the feed inlet 2, the switch 302 is turned on, water in the water tank 301 can reach the water outlet pipe 304 through the water pipe 303 and finally be sprayed out through the atomizing nozzle 14, and the water can enter from the feed inlet 2 and flow along the inner wall of the material conveying pipe 3 to the discharge port 8, so that the cleaning effect on the equipment is achieved.
