[0005] The above technical purpose of the present application is realized by the following technical scheme: a scraper conveyor capable of removing residual materials, comprising a bottom plate and a conveyor frame arranged on the upper end of the bottom plate, wherein the conveyor frame is provided with a scraper conveying part, a scraper cleaning part and a cleaning component, the scraper cleaning part comprises a cleaning support, two sliding plates, two lifting plates, two cleaning brushes, a lead screw component for sliding the cleaning support left and right, the cleaning support is arranged below the scraper conveying part, the two sliding plates are symmetrically arranged on the cleaning support, the lifting plates are fixed on the sliding plates, the cleaning brushes are connected to the upper end of the lifting plates, two spline rollers are rotatably arranged on the cleaning support, a connecting shaft is arranged on the inner side of the sliding plate and is adapted to slide with the spline roller, and a linkage component is arranged between the lead screw component and the cleaning support to drive the two spline rollers to rotate synchronously.

[0006] By adopting the above technical scheme, in the process of conveying materials by the scraper conveying part, the cleaning support is pushed forward by the lead screw component, and in the process of synchronous movement with the scraper, the two spline rollers are rotated by the linkage component, the two sliding plates are synchronously lifted by the adaptation of the connecting shaft, the cleaning brushes are slid up and down under the pushing of the lifting plates, so as to push the materials adhered to the scraper down, thereby avoiding the influence of material adhesion on the conveying efficiency of the materials.

[0007] The further arrangement of the present application is that the screw rod part comprises a baffle plate installed in the inner cavity of the conveying frame, a driving motor is installed on the baffle plate, a reciprocating screw rod adapted to the baffle plate is installed at the output end of the driving motor, and two guide rods adapted to the sliding of the cleaning support are further arranged on the baffle plate.

[0008] By adopting the above technical scheme, the reciprocating screw rod is rotated by the driving motor, and the cleaning support is pushed to slide forward and backward under the guidance and limitation of the two guide rods, so that the cleaning of the material on the scraper is realized.

[0009] The further arrangement of the present application is that two vertical columns are arranged at the front and rear ends of the inner side of the cleaning support, sliding blocks adapted to the vertical columns are installed at the two ends of the sliding plate, and connecting springs are further sleeved on the vertical columns.

[0010] By adopting the above technical scheme, the sliding blocks on the two sides slide outside the vertical columns while the sliding plate is lifted, and the lifting displacement of the sliding blocks is more stable and reliable under the extension and contraction of the connecting springs.

[0011] The further arrangement of the present application is that the cleaning brush part comprises a push frame slidingly arranged on the top of the lifting plate, a plurality of extrusion springs are equidistantly arranged between the push frame and the lifting plate, a micro motor is further arranged at the end of the push frame, and a cleaning roller is installed at the output end of the micro motor.

[0015] The further arrangement of the present application is that the telescopic rod part comprises two connecting rods and a sleeve pipe slidingly connected with the two connecting rods, and an extrusion spring is arranged between the two connecting rods.

[0016] By adopting the above technical solution, while the cleaning bracket slides left and right, the two connecting rods compress the compression spring, and its end slides inside the sleeve, making the structural design more reasonable.

[0017] A further feature of the present invention is that the connecting rod has two locking blocks at one end located inside the sleeve, and the sleeve has a locking groove for the locking blocks to slide left and right.

[0018] By adopting the above technical solution, the cooperation between the locking block and the locking slot allows the connecting rod on one side to rotate synchronously through the sleeve when the connecting rod on one side rotates.

[0019] A further embodiment of the present invention is that the cleaning component includes a cleaning frame disposed at the bottom of the inner cavity of the conveyor frame, cleaning brushes are disposed on both sides of the bottom of the cleaning frame, discharge ports are disposed on both sides of the bottom of the conveyor frame, and a driving component for driving the cleaning brushes to slide back and forth is disposed at the end of the conveyor frame.

[0020] By adopting the above technical solution, the sweeping frame is controlled by the drive component to swing back and forth to both sides, and the sweeping brush pushes the material that falls at the bottom of the conveyor frame out of the discharge port, making it convenient to remove the material.

[0021] A further configuration of the present invention is as follows: the driving component includes a rotating shaft mounted on the end of the conveyor frame and an arc-shaped gear connected to the rotating shaft; the reciprocating screw has a turntable at the end near the arc-shaped gear; the upper end of the arc-shaped gear has a limiting groove; the end face of the turntable is equipped with a protrusion inserted into the limiting groove; and the cleaning frame has a rack meshing with the arc-shaped gear at the end near the arc-shaped gear.

[0022] By adopting the above technical solution, the reciprocating screw rotates while driving the turntable at the end to rotate. The cooperation between the protrusion and the limiting groove causes the arc gear to swing back and forth around the axis of rotation, causing the rack to be meshed and slide back and forth, thereby driving the sweeping frame to move back and forth to sweep the material.

[0023] A further feature of the present invention is that the inner cavity of the conveyor frame is provided with a guide rod that is slidably connected to the cleaning frame, and the upper end of the cleaning frame is provided as a slope.

[0024] By adopting the above technical solution, the guide rod guides the cleaning frame to slide stably, and the slope surface makes the material on the scraper accumulate on both sides of the bottom of the conveyor frame when it falls, making it easy to push it out.

[0025] The beneficial effects of this invention are:

[0026] 1. This invention, through the setting of the scraper cleaning component, during the process of the scraper conveyor conveying materials, pushes the cleaning bracket forward through the lead screw component. During the synchronous movement of the bracket and the scraper, the linkage component drives the two spline rollers to rotate. Through the adaptation with the connecting shaft, the two sliding plates can be pushed to rise and fall synchronously. Under the push of the lifting plate, the cleaning component is controlled to slide up and down, thereby pushing the material adhering to the scraper off, avoiding the material adhesion affecting the material conveying efficiency, and making cleaning more convenient.

[0027] 2. In this invention, by setting the upper end of the sweeping frame as a slope, the material falling from the scraper accumulates on both sides of the bottom of the conveyor frame. The sweeping frame is controlled by the drive unit to swing back and forth to both sides, and the material falling at the bottom of the conveyor frame is pushed out from the discharge port by the sweeping brush. This can greatly save labor and make the cleaning of materials more convenient.

[0028] 3. In this invention, when the scraper cleaning component is in operation, the reciprocating screw rotates while driving the turntable at the end to rotate. Through the cooperation of the protrusion and the limiting groove, the arc gear swings back and forth around the axis of rotation, causing the rack to be meshed and slide back and forth, thereby driving the sweeping frame to move back and forth. The scraper cleaning component and the sweeping component can be operated simultaneously through one drive, making the device more energy-efficient. Attached Figure Description
