The frame 1 is fixedly connected with a guide block 11. The sliding rod 10 and the guide block 11 are slidingly connected. The guide block 11 limits and guides the movement of the sliding rod 10, so that the sliding rod 10 can only move in the horizontal direction. No rotation will occur.

There is one rotating shaft in total. The rotating shaft is located at the left end of the screen 18. The rotating shaft is fixedly connected to the left end of the screen 18 and is rotationally connected to the sliding rod 10. The screen 18 is fixedly connected to a telescopic column 24, and the telescopic column 24 is slidingly connected to a sleeve. The telescopic column 24 is connected to the sleeve through a third spring 25, and the third spring 25 is located between the telescopic column 24 and the sleeve.

The upper surface of the right end of the frame 1 is provided with a slope. When the screen 18 rotates, the screen 18 rotates around the rotating shaft on the left side. When the screen 18 is reversed and reset, the screen 18 drives the telescopic column 24 on the right side to rotate. The sleeve and the frame body 1 are in contact, and under the action of the inclined plane, the third spring 25 is compressed, so that the sleeve moves into the space between the frame bodies 1. The third spring 25 is provided to keep the sleeve and the frame body 1 in contact. state, thereby facilitating support of the right end of the screen 18.

The collection box 19 and the screening box 20 are both arranged below the screen 18. The screening box 20 is located on one side of the collection box 19. The volume of the collection box 19 is larger than that of the screening box 20. The collection box 19 is used for screening. Required material collection work, the screening box 20 is used for material collection work that does not meet the screening requirements.

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

The driving mechanism includes a main shaft 26, the main shaft 26 is connected to the second gear 5 through the second one-way bearing 23, the main shaft 26 is connected to the first gear 4 through the first one-way bearing 22, the second one-way bearing 23 and the first one-way bearing 22. The bearings 22 are arranged in opposite directions.

A one-way bearing is a bearing that can rotate freely in one direction and is locked in the other direction. A one-way bearing is also called an overrunning clutch. The metal shell of a one-way bearing contains many rollers, needle rollers or balls, and the shape of its rolling seat (hole) allows it to only roll in one direction, while producing great resistance in the other direction ( So-called "one-way").

The frame 1 is rotatably connected to a third gear 6. The third gear 6 is eccentrically hinged to a connecting rod 9. The other end of the connecting rod 9 is hinged to the sliding rod 10. When the third gear 6 rotates, it can be driven by the eccentrically connected connecting rod 9. The sliding rod 10 reciprocates in the horizontal direction.

The frame body 1 is slidingly connected to a first rack 3 that moves in the horizontal direction. The first rack 3 meshes with the first gear 4 . The first rack 3 is connected to the frame 1 through a second spring 17 .

The first rack 3 is fixedly connected to the second rack 14, and the rotating shaft is fixedly connected to the fourth gear 15. The second rack 14 and the fourth gear 15 cooperate. In the initial state, the second rack 14 is located at the fourth gear 15. At this time, when the screen 18 moves to the leftmost end, the second rack 14 is still not meshed with the fourth gear 15, so the second rack 14 will not affect the normal movement of the screen 18.

When the main shaft 26 rotates, the second one-way bearing 23 is in one-way locking, so the main shaft 26 can drive the second gear 5 to rotate, and the second gear 5 drives the third gear 6 to rotate, thereby driving the screen 18 to reciprocate in the horizontal direction. , at this time, the main shaft 26 and the first gear 4 rotate relative to each other.

When the main shaft 26 reverses, the first one-way bearing 22 is in one-way locking, so the main shaft 26 can drive the first gear 4 to rotate, and the first gear 4 can drive the first rack 3 to move horizontally, thereby passing the second gear The bar 14 drives the fourth gear 15 to rotate, causing the screen 18 to rotate. At this time, the main shaft 26 and the second gear 5 rotate relative to each other.

The first rack 3 is fixedly connected to a bracket, and the second rack 14 is fixedly connected to the bracket. The bracket is also slidably connected to movable teeth 13. The movable teeth 13 are connected to the bracket through a first spring 12. One end of the first spring 12 is connected to the movable bracket. The teeth 13 are connected to each other, and the other end of the first spring 12 is connected to the bracket. The first spring 12 is used to reset the movable teeth 13. In the initial state, under the action of the first spring 12, the movable teeth 13 are located on the second teeth. Strip 14 on one side.

The length of the second rack 14 enables the fourth gear 15 to rotate within 90°. The movable teeth 13 are used to prevent the first rack 3 from moving an excessive distance. When the first rack 3 moves an excessive distance, the fourth gear 15 rotates within 90°. After the gear 15 comes into contact with the movable teeth 13, the movable teeth 13 will be driven to slide along the bracket, and at this time, the fourth gear 15 will no longer rotate.

The frame 1 is fixedly connected with a guide rail 2 arranged in the horizontal direction. The first rack 3 and the guide rail 2 are slidingly connected. The friction between the first rack 3 and the guide rail 2 is suitable enough. This friction makes it possible for the main shaft 26 to drive the second rack 2 when the main shaft 26 drives the second rack 2. When the gear 5 rotates, due to the existence of friction, the main shaft 26 and the first gear 4 rotate relative to each other, and the first gear 4 will not be driven to rotate simultaneously.

The bracket is fixedly connected with a guide rod 16 arranged in a horizontal direction, and a second spring 17 is sleeved on the guide rod 16. One end of the second spring 17 is connected to the guide rod 16, and the other end of the second spring 17 is connected to the frame body 1. 17 is used for the reset work of the guide rod 16.

Since the main shaft 26 will rotate, the rotation direction can drive the second gear 5 to rotate. Therefore, when the second spring 17 drives the first rack 3 to return, the first gear 4 will reverse and the first gear 4 will not get stuck. The second spring 17 can be used to realize the reset of the first rack 3 .

The sliding rod 10 can rotate freely around the sliding shaft. The sliding shaft is threadedly connected with a nut. The nut is located at the third gear. One side of three gears 6.

Since the movement length of the screen 18 changes after adjustment, the screen 18 can be flipped to a suitable angle by adjusting the working time of the motor 21 each time, or the working time of the motor 21 can be adjusted without changing the working time of the motor 21. Teeth 13, using the movable teeth 13, when the second rack 14 moves to the right, after the fourth gear 15 and the right end of the second rack 14 are disconnected, as the second rack 14 continues to move to the right, It will drive the movable teeth 13 to move relative to the bracket, so it will not drive the fourth gear 15 to rotate too far.

By tightening the nut, the nut can be brought into contact with the third gear 6. At this time, the slider can no longer slide in the guide groove 8. When the nut is loosened, there is a gap between the nut and the third gear 6. At this time, the nut cannot It will affect the normal movement of the sliding shaft. The sliding shaft can slide in the guide groove 8, so that the distance between the sliding shaft and the center of the third gear 6 can be adjusted to realize the adjustment of the movement length of the screen 18.

The specific working process is as follows: in the initial state, the fourth gear 15 is located on one side of the second rack 14. When the screen 18 moves to the leftmost end, the fourth gear 15 still does not mesh with the second rack 14, so The second rack 14 will not affect the normal movement of the fourth gear 15 .

Start the motor 21 and put the crushed asphalt old material into the screen 18 at the same time. The motor 21 drives the main shaft 26 to rotate. The main shaft 26 drives the second gear 5 to rotate through the second one-way bearing 23. The second gear 5 drives the third gear. 6 rotates, and the third gear 6 drives the sliding rod 10 to reciprocate in the horizontal direction through the connecting rod 9, thereby driving the screen 18 to reciprocate in the horizontal direction, realizing the screening of the crushed asphalt old materials, so that the asphalt old materials that meet the requirements can pass through the screen. The particles fall into the collection box 19. During this process, the main shaft 26 and the first gear 4 rotate relative to each other, and the first gear 4 does not rotate.

After screening for a certain period of time, the motor 21 drives the main shaft 26 to reversely rotate. The main shaft 26 drives the first gear 4 to rotate through the first one-way bearing 22. The first gear 4 drives the first rack 3 to move to the left, and the first rack 3 drives the The second rack 14 moves to the left, and the second rack 14 drives the fourth gear 15 to rotate, thereby driving the screen 18 to rotate, so that the unscreened materials are dumped into the screening box 20, thereby facilitating the subsequent recycling of old asphalt materials.
