Technical Field

[0001] This utility model relates to the field of concrete production equipment technology, and in particular to a sand and soil sorting device for concrete processing. Background Technology

[0002] Concrete is an artificial stone material made by mixing cement as a binder, sand and stone as aggregates, and water in a certain proportion, then uniformly mixing, compacting, curing and hardening it. It is one of the most important civil engineering materials in modern times.

[0003] The volume of sand and soil affects the quality of concrete to a certain extent. Therefore, the sand and soil used to prepare concrete need to be screened by a screening mechanism. For example, CN210474613U discloses a sand and gravel vibrating screen, which uses a motor to drive the screen box to vibrate and screen the sand and gravel. The sand and gravel are sent out from the discharge port, and the two sides of the screen are connected to side plates.

[0004] Although the above technical methods can achieve the screening of sand and gravel, they still have the following disadvantages: 1. In order to improve the screening effect of sand and gravel, the screen is set to be relatively long and occupies a large area; 2. The dust generated during screening is directly dispersed into the air, causing environmental pollution. Utility Model Content

[0005] Therefore, this utility model proposes a sand and soil sorting device for concrete processing, which can extend the sand and soil screening stroke, improve the screening effect, and at the same time, can treat the dust generated in the screening box to reduce the environmental pollution caused by dust.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A sand and soil sorting device for concrete processing includes a spiral screen, a spiral guide plate, a screening box, a vibrating frame, a dust suppression component, and a vibration mechanism. The vibrating frame is installed inside the screening box, and the vibration mechanism drives the vibrating frame to vibrate. The spiral screen and the spiral guide plate are fixed on the vibrating frame, with the spiral guide plate positioned below the spiral screen. A feed hopper is fixed on the screening box, with the output end of the feed hopper located above the input end of the spiral screen. The output ends of the spiral screen and the spiral guide plate extend to the outside of the screening box. The dust suppression component is connected to the screening box, and its suction end is located inside the screening box to remove dust generated during screening.

[0008] Furthermore, the vibrating frame includes a vibrating base plate, a vibrating cylinder, and several pressure springs. The vibrating base plate is fixed to the bottom of the screening box by several pressure springs, and the vibrating cylinder is fixed to the vibrating base plate. The vibrating cylinder is located outside the spiral screen and the spiral guide plate.

[0009] Furthermore, baffles are provided on the inner sides of the spiral screen and the spiral guide plate respectively.

[0010] Furthermore, the screening box is provided with a discharge port, and the output ends of the spiral screen and the spiral guide plate extend to the outside of the screening box through the discharge port.

[0011] Furthermore, the screening box includes a box body, a box cover, and several supporting legs, with the supporting legs fixed to the bottom of the box body and the box cover covering the top of the box body.

[0012] Furthermore, the dust suppression assembly includes a suction pipe and a dust suppression box. One end of the suction pipe extends into the screening box, and the other end of the suction pipe is connected to the dust suppression box through a connecting pipe. The suction pipe has several suction holes on its wall.

[0013] Furthermore, the dust suction pipe is provided with an installation plate, the screening box is provided with an installation groove, and the installation plate is disposed in the installation groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The spiral screen is fixed on the vibrating frame, which can drive the spiral screen to vibrate. Sand and soil are screened through the spiral screen, which extends the path of sand and soil on the spiral screen and improves the screening effect.

[0016] 2. The dust collection end of the dust suppression component is located inside the screening box. When dust is generated during the screening of sand and soil, the dust suppression component can extract the dust from the screening box and discharge the extracted dust after dust suppression treatment, which can reduce the environmental pollution caused by dust.

[0017] 3. The output port of the feed hopper has a rectangular cross-section, which allows material to be fed along the width of the spiral screen, effectively preventing the accumulation of sand and soil. Attached Figure Description

The vibration mechanism 15 is used to drive the vibrating frame 7 to vibrate. The vibration mechanism 15 is prior art and will not be described in detail here. The spiral screen 1 and the spiral guide plate 2 are fixed on the vibrating frame 7. The spiral screen 1 can extend the sand and soil screening stroke, reduce the footprint of the spiral screen 1, and improve the sand and soil screening effect. The spiral guide plate 2 is set below the spiral screen 1. The sand and soil screened by the spiral screen 1 falls onto the spiral guide plate 2 below. The screening box... A feed hopper 16 is fixed on the screen 3. The output end of the feed hopper 16 is located above the input end of the spiral screen 1. The cross-section of the output port of the feed hopper 16 is rectangular, which can discharge material along the width direction of the spiral screen 1, effectively avoiding the accumulation of sand and soil.
