The collecting box 19 and the screening box 20, the collecting box 19 and the screening box 20 are arranged below the screen 18, the screening box 20 is located on one side of the collecting box 19, the volume of the collecting box 19 is larger than that of the screening box 20, the collecting box 19 is used for collecting materials meeting screening requirements, and the screening box 20 is used for collecting materials not meeting the screening requirements.

The driving mechanism respectively drives the sliding rod 10 to move horizontally and the rotating shaft to rotate around the sliding rod 10, so that the materials on the screen 18 fall into the collecting box 19 after being screened or the materials on the screen 18 are poured into the screening box 20.

The driving mechanism comprises a main shaft 26, the main shaft 26 is connected with a second gear 5 through a second one-way bearing 23, the main shaft 26 is connected with a first gear 4 through a first one-way bearing 22, and the setting directions of the second one-way bearing 23 and the first one-way bearing 22 are opposite.

The one-way bearing is a bearing which can rotate freely in one direction and is locked in the other direction, and the one-way bearing is also called an overrunning clutch. The metal housing of the one-way bearing contains a plurality of rollers, needles or balls, and its rolling seat (pockets) is shaped so that it can roll only in one direction and a large resistance in the other direction (so-called "one-way").

The frame body 1 is rotationally connected with a third gear 6, the third gear 6 is eccentrically hinged with a connecting rod 9, the other end of the connecting rod 9 is hinged with a slide rod 10, and when the third gear 6 rotates, the connecting rod 9 which is eccentrically connected can drive the slide rod 10 to reciprocate in the horizontal direction.

The frame body 1 is connected with a first rack 3 which moves in the horizontal direction in a sliding manner, the first rack 3 is meshed with a first gear 4, and the first rack 3 is connected with the frame body 1 through a second spring 17.

The first rack 3 is fixedly connected with the second rack 14, the rotating shaft is fixedly connected with the fourth gear 15, the second rack 14 is matched with the fourth gear 15, in an initial state, the second rack 14 is positioned on one side of the fourth gear 15, and at the moment, when the screen 18 moves to the leftmost end, the second rack 14 is still not meshed with the fourth gear 15, so that the second rack 14 cannot influence the normal movement of the screen 18.

When the main shaft 26 rotates, the second unidirectional bearing 23 is in unidirectional locking, so that the main shaft 26 can drive the second gear 5 to rotate, the second gear 5 can drive the third gear 6 to rotate, and the screen 18 can be driven to reciprocate in the horizontal direction, and the main shaft 26 and the first gear 4 rotate relatively.

When the main shaft 26 rotates reversely, the first one-way bearing 22 is in one-way locking, so that the main shaft 26 can drive the first gear 4 to rotate, the first gear 4 can drive the first rack 3 to move horizontally, and the second rack 14 can drive the fourth gear 15 to rotate, so that the screen 18 rotates, and the main shaft 26 and the second gear 5 rotate relatively.

The first rack 3 is fixedly connected with a support, the second rack 14 is fixedly connected with the support, the support is further connected with a movable tooth 13 in a sliding mode, the movable tooth 13 is connected with the support through a first spring 12, one end of the first spring 12 is connected with the movable tooth 13, the other end of the first spring 12 is connected with the support, the first spring 12 is used for resetting the movable tooth 13, and in an initial state, the movable tooth 13 is located on one side of the second rack 14 under the action of the first spring 12.

The length of the second rack 14 makes the fourth gear 15 rotate within 90 degrees, the movable tooth 13 is used for preventing the first rack 3 from moving too much distance, when the first rack 3 moves too much distance, the fourth gear 15 contacts with the movable tooth 13 and then drives the movable tooth 13 to slide along the bracket, and at the moment, the fourth gear 15 does not rotate any more.

The frame body 1 is fixedly connected with the guide rail 2 that the horizontal direction set up, and first rack 3 and guide rail 2 sliding connection, frictional force between first rack 3 and the guide rail 2 is enough suitable, and this frictional force makes when main shaft 26 drives second gear 5 and rotates, because frictional force's existence, main shaft 26 and first gear 4 take place relative rotation this moment, and can not drive first gear 4 and rotate simultaneously.

The support fixedly connected with guide bar 16 that the horizontal direction set up, second spring 17 cover are established on guide bar 16, and second spring 17 one end links to each other with guide bar 16, and the second spring 17 other end links to each other with support body 1, and second spring 17 is used for the reset work of guide bar 16.

Because the spindle 26 can rotate, the second gear 5 can be driven to rotate in the rotating direction, when the second spring 17 drives the first rack 3 to reset, the first gear 4 is reversed, the first gear 4 cannot be blocked, and the second spring 17 can be used for resetting the first rack 3.

Example two
