[0025] 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 scope of protection of the present utility model.

[0026] This utility model provides a scraper conveyor for transporting gangue, such as... Figure 1 and Figure 2 As shown, the device includes a housing 1, a base plate 5, and a vibrating motor 6. Support seats 11 are fixedly connected to the bottom of both ends of the housing 1. Both the upper and lower surfaces of the housing 1 are open. The base plate 5 is rotatably connected to the lower opening of the housing 1 via a rotating shaft. The upper opening is used for material feeding, while the lower opening mates with the base plate 5. The rotating shaft of the base plate 5 is located at one end of the housing 1 and is perpendicular to the length direction of the housing 1. This allows for flexible rotation of the base plate 5, creating conditions for vibratory material cleaning. Figure 6As shown, a discharge port 52 is provided through the surface of the base plate 5 away from the rotating shaft. Multiple slides 12 are linearly and evenly distributed on both sides of the housing 1. A sliding groove 121 is provided through the side of the slide 12. The sliding groove 121 is arc-shaped. The center of the multiple sliding grooves 121 is coaxial with the center of the rotating shaft of the base plate 5. The sliding groove 121 of the slide 12 closest to the rotating shaft of the base plate 5 has the shortest arc length. The arc length of the sliding groove 121 of the slide 12 increases proportionally in the direction away from the rotating shaft of the base plate 5. Multiple side rods 51 are linearly and evenly distributed on both sides of the base plate 5. The multiple side rods 51 correspond one-to-one with the slides 12 on both sides of the housing 1, and the end of each side rod 51 is slidably connected in the sliding groove 121 of the corresponding slide 12.

[0027] The slide blocks 12 are linearly and evenly distributed on both sides of the housing 1. The sliding grooves 121 on their sides adopt an arc-shaped structure, and the center of all the sliding grooves 121 is coaxial with the center of the rotation axis of the base plate 5. This coaxial design constructs a rotational coordinate system with the rotation axis as the center, so that when the base plate 5 rotates, the sliding trajectory of the side rods 51 always follows the law of circular motion. The closer the slide block 12 is to the rotation axis, the shorter the arc length of its sliding groove 121, while the arc length of the sliding groove 121 of the slide block 12 further away from the rotation axis increases proportionally. This design is essentially based on the geometric principle of "the longer the radius, the longer the arc length" in circular motion, ensuring that when the base plate 5 rotates, the sliding distance of each side rod 51 in the corresponding sliding groove 121 forms a precise mathematical match with the rotation angle of the base plate 5. For example, when the base plate 5 rotates by an angle θ, the corresponding arc length of the slide groove 121 with radius r is r×θ. By increasing the arc length proportionally, the side rods 51 at different positions can complete the corresponding displacement synchronously, thus preventing the base plate 5 from twisting due to uneven force.

[0028] like Figure 2 and Figure 3 As shown, a limiting seat 13 is provided between every two adjacent slides 12. A threaded rod 7 is inserted into the limiting seat 13. The threaded rod 7 is located at the lower end of the base plate 5. The vibration motor 6 is fixed on the lower surface of the base plate 5. The vibration direction of the vibration motor 6 is perpendicular to the rotation plane of the base plate 5.

[0029] like Figure 4 and Figure 5As shown, a through circular hole is provided on the limiting seat 13. The threaded rod 7 passes through the circular hole of one limiting seat 13 and extends into the circular hole of the other limiting seat 13. The outer peripheral side of the threaded rod 7 abuts against the lower surface of the base plate 5. When the base plate 5 is in a horizontal transport position, the side rod 51 is located at the upper starting end of the slide groove 121. A fixing nut is threaded onto the side rod 51. By tightening the fixing nuts on the side rods 51 on both sides of the base plate 5, the side rods 51 can be clamped and fixed to the box body 1. The fixing nuts on both sides are clamped on both sides of the box body 1. At this time, the slide 12 provides multi-point support to the base plate 5 through the side rods 51. At the same time, the threaded rod 7 is inserted into the circular hole of the limiting seat 13 on both sides. The threaded rod 7 reinforces and supports the base plate 5 to prevent it from deforming under load. After the threaded rod 7 is inserted, the nut is screwed in to prevent the threaded rod 7 from slipping off.

[0030] like Figure 3 and Figure 7 As shown, when it is necessary to clean up residual materials, take out the threaded rod 7, the base plate 5 rotates around the pivot, and each side rod 51 slides to the bottom in the corresponding slide groove 121. Tighten the fixing nut on the side rod 51 to fix the base plate 5. At this time, the base plate 5 is in an inclined state. The end of the base plate 5 with the discharge port 52 is lower than the end of the pivot of the base plate 5, so that the residual gangue inside the box 1 slides down from the base plate 5, which plays the role of slag discharge. The vibration motor 6 can speed up the slag discharge and also ensure that the gangue is completely removed.

[0031] like Figure 1 and Figure 2 As shown, drive assemblies are provided on both sides of the interior of the housing 1. The two sets of drive assemblies are symmetrically arranged. Each drive assembly includes a set of rotating wheels 2 and a drive chain 3. The set of rotating wheels 2 includes a driving wheel 21 and a driven wheel 22. The driving wheel 21 and the driven wheel 22 are rotatably connected to both ends of the housing 1, and the drive chain 3 is sleeved on the driving wheel 21 and the driven wheel 22. Annular grooves are formed on the outer circumferential surfaces of the driving wheel 21 and the driven wheel 22, and the drive chain 3 is embedded in the annular grooves. Multiple scrapers 31 are fixedly connected to the drive chain 3 located between the two sets of drive assemblies on both sides of the interior of the housing 1. The two ends of the scrapers 31 are fixed to the two drive chains 3, and the multiple scrapers 31 are evenly distributed along the drive chain 3. A drive motor 4 is fixedly connected to the outer surface of the housing 1. The drive shaft of the drive motor 4 is coaxial with the axis of the two symmetrically arranged driving wheels 21 at one end of the housing 1, and both driving wheels 21 are fixed on the drive shaft of the drive motor 4. When the device is in transport, the base plate 5 is in a horizontal position. Starting the drive motor 4 can drive the two symmetrically arranged active rotating wheels 21 to rotate synchronously, so that the drive chain 3 runs. Multiple scrapers 31 are fixed at equal intervals between the two drive chains 3 to form a continuous material pushing array. The scrapers 31 move horizontally and linearly with the chain, and their plate surfaces perpendicular to the direction of movement push the material forward and transport it to the discharge port 52 for discharge.

[0032] Using this utility model, such as Figure 1 and Figure 2 As shown, when the device is being transported, the base plate 5 is in a horizontal position. Starting the drive motor 4 can drive the two symmetrically arranged active rotating wheels 21 to rotate synchronously, causing the drive chain 3 to run. The scraper 31 moves horizontally in a straight line with the chain, pushing the material forward. When it is necessary to clean up the residual material, the threaded insert 7 is taken out, the base plate 5 rotates around the rotating shaft, and each side rod 51 slides to the bottom in the corresponding sliding groove 121. The fixing nuts on the side rods 51 are tightened to fix the base plate 5. At this time, the base plate 5 is in an inclined state, and the end of the base plate 5 with the discharge port 52 is lower than the end of the rotating shaft of the base plate 5, so that the residual gangue inside the box 1 slides down from the base plate 5, which plays the role of slag discharge. The vibration motor 6 can speed up the slag discharge and also ensure that the gangue is completely removed.

[0033] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
