[0034] When using the bouncing screen to sort construction and decoration waste, in order to improve the screening effect of light materials and increase the service life of the screen plate, such as Figure 1-Figure 3 As shown, the utility model provides a spring screen, which comprises a frame 1, a plurality of screen plates 2, two sets of driving components 3 and a blast device 4.

[0035] The frame 1 has a containing cavity, the frame 1 is arranged upwardly and tilted along a first direction, a first discharge port is provided at the lower end of the frame 1, a second discharge port is provided at the upper end of the frame 1, and a feed port connected to the containing cavity is provided on the upper side of the frame 1. The sieve plate 2 is arranged in the containing cavity along the first direction, and a plurality of reinforcing plates are fixedly and spaced apart on the upper end surface of the sieve plate 2. Two groups of driving components 3 are arranged in the frame 1 at intervals along the first direction, and the driving components 3 are connected to the sieve plate 2 in a transmission manner, and the two groups of driving components 3 are used to drive the sieve plate 2 to bounce and vibrate; the blowing device 4 is connected to the containing cavity, and is used to blow air into the containing cavity along the first direction.

[0036] In the process of sorting construction and decoration waste, the frame 1 is arranged upward along the first direction, and the construction and decoration waste is poured from the feed port. The two sets of drive components 3 drive the screen plate 2 to bounce and vibrate, so as to sort. The small and heavy garbage leaks through the sieve holes on the screen plate 2, and the large and heavy garbage is discharged from the first discharge port under the action of gravity. The light garbage moves upward along the first direction under the action of the blast device 4. In this process, since a plurality of reinforcing plates are arranged at intervals on the screen plate 2, a grid is formed between adjacent reinforcing plates. The light garbage moves upward under the action of the blast device 4, and when it falls, it enters the upper grid, thereby achieving the climbing and lifting of the light garbage, and finally discharged from the second discharge port. Through the above arrangement, the screening effect of light materials can be improved. Moreover, by arranging the reinforcing plate on the screen plate 2, the strength of the screen plate 2 can be improved, so that when sorting heavy construction waste, it can withstand the impact of construction waste and improve the service life of the screen plate 2.

[0037] Further, the driving assembly 3 includes a driving member 31 and a plurality of transmission assemblies connected in series, the driving member 31 is connected to the transmission assembly located at the end, and the plurality of transmission assemblies are arranged one by one with the plurality of sieve plates 2, and the driving member 31 can drive the transmission assembly to rotate, so as to drive the sieve plates 2 to bounce and vibrate. Specifically, in the present embodiment, the driving member 31 is a motor, and the motor is fixedly mounted in the frame 1, and the output shaft of the motor rotates to drive the transmission assembly located at the end, and the transmission assembly at the end synchronously drives the transmission assembly connected in series to move, thereby driving the sieve plates 2 to lift and lower, and realize the effect of bouncing and vibrating. The use of a motor facilitates the control of the rotation speed, steering, and start and stop. In other embodiments, an engine, a hydraulic motor, etc. may also be used, and no excessive restrictions are made here.

[0038] Further, the transmission assembly includes a first rotating shaft, a fixed bearing seat 32, a second rotating shaft, a movable bearing seat 35, a first clamping block 33 and a second clamping block 34, the fixed bearing seat 32 is fixedly arranged in the frame 1, the first rotating shaft is rotatably arranged in the fixed bearing seat 32, and one end of the first rotating shaft is connected to the driving member 31 for transmission, the other end of the first rotating shaft is connected to the first clamping block 33, the other end of the first clamping block 33 is connected to one end of the second rotating shaft, the movable bearing seat 35 is rotatably sleeved on the second rotating shaft, and the movable bearing seat 35 is connected to the sieve plate 2, the second clamping block 34 is connected to the other end of the second rotating shaft, and one end of the second clamping block 34 is connected to the first rotating shaft of the adjacent transmission assembly. When the driving member 31 drives the first rotating shaft to rotate, the first rotating shaft drives the second rotating shaft to rotate around the axis of the first rotating shaft through the first clamping block 33 and the second clamping block 34, and the second rotating shaft drives the sieve plate 2 to perform a lifting and lowering circulation movement, thereby realizing the bouncing movement of the sieve plate 2. During the rotation of the second clamping block 34, the second clamping block 34 synchronously drives the rotation of the adjacent first rotating shaft, thereby realizing the movement of the adjacent transmission components, and so on, realizing the vibration of all the sieve plates 2. When one of the transmission components is worn, the corresponding transmission component can be replaced without replacing all the transmission components, which reduces the manufacturing difficulty, facilitates maintenance, and reduces maintenance costs. At the same time, since the movable bearing seat 35 is directly connected to the sieve plate 2, it can prevent the sieve plate 2 from being suspended in the air, thereby improving the carrying capacity.

[0039] Furthermore, the end section of the first rotating shaft is a regular hexagon, and the first clamping block 33 and the second clamping block 34 are both provided with a regular hexagonal hole that matches the end of the first rotating shaft. Through the above arrangement, it is convenient for the first clamping block 33 and the second clamping block 34 to be connected to the first rotating shaft, and the transmission can be effectively realized. In other embodiments, the end section of the first rotating shaft can also be designed to be a triangle, a quadrilateral, a pentagon, etc., and no excessive restrictions are made here. Moreover, by adjusting the inclination angle of the first clamping block 33 and the second clamping block 34, the position of the second rotating shaft can be adjusted, thereby achieving the effect of adjusting the amplitude of the sieve plate 2.

[0040] Furthermore, the end section of the second rotating shaft is a regular octagon, and the first clamping block 33 and the second clamping block 34 are both provided with a regular octagonal hole that matches the end of the second rotating shaft. Through the above arrangement, it is convenient to connect the first clamping block 33 and the second clamping block 34 with the second rotating shaft, and the transmission can be effectively realized. In other embodiments, the end section of the second rotating shaft can also be designed to be a triangle, a quadrilateral, a pentagon, etc., and no excessive restrictions are made here.

[0041] Furthermore, the bouncing screen further includes an adjustment base 5, which is arranged on the lower side of the frame 1, and the adjustment base 5 is used to adjust the inclination angle of the frame 1. The inclination angle of the bouncing screen also needs to be adjusted for different types of construction waste. Therefore, by setting the adjustment base 5, the inclination angle of the frame 1 can be quickly adjusted to meet the screening of different types of construction waste.

[0042] Furthermore, if Figure 2 As shown, the adjustment base 5 includes a mounting frame 51 and an adjustment support frame 52, the mounting frame 51 is fixedly arranged on the frame 1, the adjustment support frame 52 is arranged on the mounting frame 51, and the angle between the adjustment support frame 52 and the mounting frame 51 can be adjusted. In this embodiment, the mounting frame 51 is in an inverted triangle shape, and the adjustment support frame 52 is in a triangular shape. By adjusting the angle between the mounting frame 51 and the adjustment support frame 52, the inclination angle of the frame 1 can be adjusted. The adjustment base 5 can be arranged in multiple groups on the frame 1 along the first direction at intervals, and no excessive restrictions are made here.

[0043] Furthermore, a plurality of support members 521 are arranged at intervals on the adjustment support frame 52, and the extension length of the support member 521 relative to the lower end surface of the adjustment support frame 52 can be adjusted. Specifically, the support member 521 is a bolt, and by adjusting the extension length of the support member 521 relative to the lower end surface of the adjustment support frame 52, the height of the frame 1 can be adjusted to adapt to different application occasions.

[0044] Furthermore, the air blowing device 4 includes a blower 41 and at least one air duct 42, one end of the air duct 42 is connected to the air outlet of the blower 41, and the other end of the air duct 42 is connected to the receiving chamber of the frame 1. Through the operation of the blower 41, the high-speed airflow enters the receiving chamber through the air duct 42. During the screening process, the high-speed airflow will blow up the light-weight garbage that is bounced up and move it toward the second discharge port until it is discharged from the second discharge port. In addition, in the process of arranging the air duct 42, the number of air ducts 42 is arranged according to the width of different receiving chambers, so as to effectively meet the sorting of light-weight garbage.

[0045] Furthermore, the frame 1 includes a rectangular support frame 11, a wear-resistant plate 12 is welded on the side of the support frame 11, and a channel steel is welded on the lower side of the support frame 11, and the channel steel and the wear-resistant plate 12 are surrounded to form a receiving cavity.

By providing the channel steel, the garbage with a small volume passing through the screen plate 2 can be accommodated and collected. At the same time, a canvas bag can be set at the lower end of the channel steel for collection.

[0046] The working process of this spring screen is as follows:

[0047] First, the bouncing screen is installed at an angle, and then the driving member 31 and the blower 41 are started. The construction and renovation waste is poured into the accommodating cavity of the frame 1 through the feed port, and the sieve plate 2 screens the waste. The small and heavy materials can fall through the sieve holes on the sieve plate 2, and the large and heavy materials roll off the sieve plate 2. With the assistance of the blower 41, the light materials climb up along the sieve plate 2 and are discharged from the second discharge port, thereby completing the screening of the materials.
