Description

Technical Field

[0001] This utility model relates to the field of belt conveyor cleaning technology, specifically to a flat-push cleaning device. Background Technology

[0002] Belt conveyors are widely used in industries such as mining, but during transportation, material residues can remain on the belt, especially at the head hopper. Existing cleaning devices have many problems, such as incomplete cleaning, complex structure, and susceptibility to dust-related failures.

[0003] Patent document CN221069912U describes a semi-automatic coal cleaning device for the head hopper of a belt conveyor. It comprises a receiving plate, a slide plate, a movable rod, a scraper, a polyurethane cleaning pad, a top plate, a power assembly, and a guide assembly. The forward and reverse rotation of a motor drives the relative movement of gears and racks, causing the scraper to reciprocate along the slide plate. This cleans the coal accumulated at the head of the conveyor belt, removing it into the head hopper. However, this device is more like a third-stage cleaner; residual material is still carried out of the hopper by the belt movement, failing to completely clean the hopper. Furthermore, it requires manual operation and does not reduce labor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flat-push cleaning device to solve the above-mentioned problems.

[0005] This utility model provides the following technical solution: A horizontal sweeping device includes: a thrust mechanism comprising an electrical control system, an electric push rod, and a connecting rod; a trolley mechanism comprising a frame, a set of wheels, and a sweeping plate; the frame is connected to the two sets of wheels on both sides; the sweeping plate is hinged to the connecting rod of the thrust mechanism at its middle part, and hinged to the frame at both ends at its upper parts, and is rotatable around the hinge point; and a device base comprising a frame and a flip plate, wherein the frame has a travel track on both sides, and the travel track has a sweeping plate lifting and lowering opening for lifting and lowering the sweeping plate.

[0006] Furthermore, two launching and landing openings are provided on each side of the walking track, including a launching opening and a landing opening; the flap is installed at the lower part of the launching opening and is hinged to the lower surface of the walking track; the hinged end of the flap is tangent to the edge of the launching opening, and the other end is supported by the bottom.

[0007] Furthermore, the sweeping plate is provided with opening rods at the lower part of both ends. The opening rods are L in length, protrude from the outside of the sweeping plate, and the length L is less than the width of the lifting and lowering opening, so that they can pass through the lifting and lowering opening of the walking track.

[0008] Furthermore, the width of the landing opening is 1.1 to 1.3L.

[0009] Furthermore, the frame is provided with a limiting protrusion on one side of the sweeping plate, the limiting protrusion being used to limit the clockwise rotation of the sweeping plate.

[0010] Furthermore, the walking track is symmetrically arranged from left to right, including a walking surface and a side surface. The width of the walking surface is W, and the position of the walking surface 0.3 to 0.6W from the center side of the frame is the walking surface of the opening rod.

[0011] Furthermore, the traveling wheel set includes support wheels and limiting wheels. The support wheels travel on the traveling track, and the limiting wheels press against the two sides of the traveling track to ensure that the trolley mechanism travels along the track direction.

[0012] Furthermore, one end of the frame extends into the funnel.

[0013] This utility model has the following beneficial technical effects: This invention utilizes the coordination of a connecting rod and a flap to achieve the lifting and lowering of the cleaning plate at the inlet, enabling the cleaning plate to avoid accumulated materials in one direction while cleaning in another. This prevents materials from accumulating on one side without being cleaned, and sweeps the residual materials brought out of the funnel area by the cleaner into the funnel. This invention achieves fully automatic cleaning and reduces manual labor.

[0014] The device of this utility model adopts a gravity-driven flap and cleaning plate design, which is not affected by on-site dust and is suitable for use in dusty environments such as mines, with high reliability. This utility model adopts a simple and compact structure, and uses a single power source to realize the operation of the entire device, which is low in cost and practical in function.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example like Figure 1-5 A horizontal sweeping device includes: a thrust mechanism 100, comprising an electrical control system, an electric push rod, and a connecting rod; a trolley mechanism 200, comprising a frame 210, a set of walking wheels 220, and a sweeping plate 230; the frame 210 is connected to the walking wheels 220 on both sides; the sweeping plate 230 is hinged to the connecting rod of the thrust mechanism 100 at its middle part, and hinged to the upper parts of both ends of the frame 210, and can rotate around the hinge point; a device base 300, comprising a frame 310 and a flip plate 320, wherein the frame 310 is provided with walking tracks 311 on both sides, and the walking tracks 311 are provided with sweeping plate lifting and lowering openings 311-1 for lifting and lowering the sweeping plate 230; one end of the frame 310 extends into a funnel.

[0019] like Figure 4 As shown in Figure 8, two starting and ending openings 311-1 are provided on each side of the walking track 311, including a starting opening and an ending opening; the starting opening is located near the starting point, and the ending opening is located near the ending point; the flap 320 is installed at the lower part of the starting opening and is hinged to the lower surface of the walking track 311; the hinged end of the flap 320 is tangent to the edge of the starting opening, and the other end is supported by the bottom.

[0020] like Figure 3 As shown in Figure 6, the sweeping plate 230 has opening rods 231 at the lower part of both ends. The opening rods 231 are L in length, protrude from the outside of the sweeping plate, and the length L is less than the width of the lifting opening 311-1, so that they can pass through the lifting opening 311-1 of the walking track 311. The width of the lifting opening 311-1 is 1.1 to 1.3L.

[0021] like Figure 3 As shown in Figure 7, the frame 210 has a limiting protrusion 211 on one side of the sweeping plate 230, which is used to limit the clockwise rotation of the sweeping plate 230.

[0022] like Figure 4 As shown, the walking track 311 is symmetrically arranged on the left and right sides, including a walking surface and a side surface. The width of the walking surface is W, and the position of the walking surface 0.3 to 0.6W from the center side of the frame is the walking surface of the opening rod.

[0023] like Figure 5 As shown, the traveling wheel assembly 220 includes a support wheel 221 and a limiting wheel 222. The support wheel 221 travels on the traveling track 311, and the limiting wheel 222 presses against the two sides of the traveling track 211 to ensure that the trolley mechanism 200 travels along the track direction.

[0024] The working principle of this utility model is as follows: the movement of the trolley mechanism 200 is divided into two processes: the outward journey (starting point → ending point) and the return journey (ending point → starting point). Figure 1 (Illustration). During movement, restricted by the limiting wheel 222, the trolley's traveling wheel set 220 moves along the track direction. On the outward journey, the sweeping plate 230 rotates counterclockwise along the inclined surface of the flip plate 320 and is lifted after passing the starting point, and the trolley moves towards the end of the track; the sweeping plate 230 falls down at the dropping point due to gravity; on the return journey, the sweeping plate 230 has fallen down, and the trolley moves towards the starting point of the track.

[0025] Outward movement: The thrust mechanism 100 drives the sweeping plate 230 to move along the travel track 311 towards the end of the track via a connecting rod. As the flap 320 falls freely under gravity, one end of it abuts against the bottom, forming an inclined surface. The opening rod 231 contacts the bottom end of the inclined surface of the flap 320 and moves upward along the inclined surface. The opening rod 231 enters the opening rod travel surface of the track through the opening, thereby causing the sweeping plate 230 to rotate counterclockwise around the upper hinge point (from...). Figure 1 (Viewed from the side) Lift up to avoid the material to be cleaned; when the trolley moves close to the end of the track, the opening rod 231 of the cleaning plate falls through the track opening, and the cleaning plate 230 returns to the vertical state under the action of gravity. Return stroke: The thrust mechanism 100 drives the cleaning plate 230 to move towards the funnel via the connecting rod. The cleaning plate 230 contacts the material and is in a vertical position, sweeping the accumulated material back to the funnel. During the cleaning process, the opening rod at the bottom of the cleaning plate lifts the flap 320 and passes through it, returning to the initial point.

[0026] During the return stroke, if the material is highly viscous or accumulates excessively, the cleaning plate will rotate clockwise (from...). Figure 1 (Viewed from the side) The rotation trend will be blocked by the single-sided movement restriction boss 211 of the frame, which will use greater thrust to sweep away the accumulated material.

[0027] When this device is working, it continuously repeats the outward and inward journeys, pushing the scattered material into the funnel.

[0028] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
