[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown in this embodiment, a vibrating screen for construction includes a housing 1. A first motor 2 is fixedly connected to the top of the housing 1. A drive gear 3 is fixedly sleeved on the output shaft of the first motor 2. A transmission gear 4 meshes with the bottom of the drive gear 3. A rotating rod 5 is fixedly connected to the inner wall of the transmission gear 4. A rotating seat 6 is rotatably connected to the surface of the rotating rod 5. A rotating block 7 is fixedly sleeved on the surface of the rotating rod 5. A dust-collecting plate 8 is fixedly connected to the bottom end of the rotating block 7. A collection pipe 9 is fixedly connected to the top of the dust-collecting plate 8. A dust collection box 10 is fixedly connected to the end of the collection pipe 9 away from the dust-collecting plate 8. A fan 11 is fixedly connected to the side of the dust collection box 10 away from the first motor 2.

[0024] By starting the fan 11, it rotates at high speed and creates negative pressure suction in the dust collection box 10, thereby collecting the dust generated during sand and gravel screening into the dust collection box 10 through the dust collection plate 8, reducing its adhesion to the inner wall of the box 1 and preventing dust from leaking into the air. At the same time, the first motor 2 is started, and its output shaft drives the drive gear 3 to rotate. Since the transmission gear 4 and the drive gear 3 mesh, the rotating rod 5 drives the rotating block 7 and the dust collection plate 8 to rotate, thereby adjusting the tilt angle of the dust collection plate 8 to adjust its working range and improve the dust collection effect.

[0025] The top of the housing 1 is provided with a rotating groove, the drive gear 3 and the transmission gear 4 are located inside the rotating groove, the rotating base 6 is fixedly connected to the housing 1, and the dust collection box 10 is located at the top of the housing 1.

[0026] The top of the box 1 is fixedly connected to the inlet 12, the front of the box 1 is slidably connected to the side plate 13, the left and right sides of the box 1 are provided with the discharge trough 14, and the left and right sides of the box 1 are fixedly connected to the collection box 15.

[0027] A mounting housing 16 is fixedly connected to the left side of the housing 1. A second motor 17 is fixedly connected to the side of the mounting housing 16 away from the housing 1. A drive wheel 18 is fixedly sleeved on the output shaft of the second motor 17. A belt 19 is provided on the surface of the drive wheel 18. A transmission wheel 20 is provided on the side of the belt 19 away from the drive wheel 18. A deflection assembly 21 is fixedly connected to the inner wall of the drive wheel 18 and the transmission wheel 20.

[0028] By starting the second motor 17, its output shaft drives the drive wheel 18 to rotate, and transmits the power to the transmission wheel 20 through the belt 19. This causes the drive wheel 18 and the transmission wheel 20 to drive the deflection assembly 21 to rotate. After the eccentric plate on the eccentric assembly rotates to a certain angle, it contacts the screen 25 and presses it downwards. The first spring 24 is compressed and contracted. After the eccentric plate separates from the screen 25, the screen 25 vibrates under the elastic force of the first spring 24, thereby accelerating the movement of sand and gravel and preventing irregular sand and gravel from getting stuck inside the mesh and causing blockage, which would affect the normal operation of the screen 25.

[0029] The drive wheel 18 and transmission wheel 20 are located inside the mounting housing 16. The deflection assembly 21 consists of a rotating shaft and an eccentric plate, and the rotating shaft is rotatably connected to the housing 1.

[0030] The left and right sides of the housing 1 are provided with movable slots 22. The inside of the movable slots 22 is slidably connected to the mounting plate 23. The top of the mounting plate 23 is fixedly connected to the first spring 24. The top of the first spring 24 is provided with a screen 25. The top of the mounting plate 23 is rotatably connected to the rotating plate 26. The top of the rotating plate 26 is fixedly connected to the second spring 27. The top of the second spring 27 is fixedly connected to the positioning rod 28.

[0031] By setting two screens 25 inside the box 1, with the mesh size of the upper screen 25 being larger than that of the lower screen, sand and gravel of different volumes can be screened. After screening, the side plate 13 is pulled to slide in the groove on the box 1. After being pulled up to a certain height, the mounting plate 23 is pulled outward to remove it from the moving groove 22. The positioning rod 28 is pulled upward to disengage it from the mesh of the screen 25, and the second spring 27 is stretched. The rotating plate 26 is rotated. After rotating to a certain angle, the rotating plate 26 separates from the screen 25, and the screen 25 can be taken out for cleaning or replacement.

[0032] There are two mounting plates 23, each consisting of a sliding plate and a ramp. There are four first springs 24 located at the four corners of the mounting plates 23. The screen 25 is in contact with the rotating plate 26, and the positioning rod 28 is slidably connected to the rotating plate 26.

[0033] This utility model provides a vibrating screen for construction, the specific working principle of which is as follows:

[0034] In use, sand and gravel are fed into the housing 1 through the feed inlet 12. Two inclined screens 25 inside the housing screen 1 screen the sand and gravel. The second motor 17 is started, and its output shaft drives the drive wheel 18 to rotate. Power is transmitted to the transmission wheel 20 via the belt 19, causing the drive wheel 18 and transmission wheel 20 to rotate the deflection assembly 21. After the eccentric plate on the eccentric assembly rotates to a certain angle, it contacts the screen 25 and presses it downwards. The first spring 24 is compressed and contracts. After the eccentric plate separates from the screen 25, the screen 25 vibrates under the elastic force of the first spring 24. The sand and gravel move quickly, and the screened sand and gravel are collected into the collection box 15 through the feeding chute 14, thereby classifying and collecting sand and gravel of different volumes. At the same time as the sand and gravel is screened, the fan 11 is started, which rotates at high speed and forms a negative pressure suction in the dust collection box 10, thereby collecting the dust generated during the sand and gravel screening into the dust collection box 10 through the dust suction plate 8. At the same time, the first motor 2 is started, and its output shaft drives the drive gear 3 to rotate, the transmission gear 4 rotates accordingly, and the rotating rod 5 drives the rotating block 7 and the dust suction plate 8 to rotate, thereby adjusting the tilt angle of the dust suction plate 8 and adjusting the dust suction range.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
