[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In one embodiment, see Figure 1-Figure 10 , a mullite sand conveying device, comprising a base 1, a material guiding mechanism 2 and a material pushing mechanism 3;

[0029] The pushing mechanism 3 includes a driven pulley 21 arranged at the ends of the fixed support beam 4 and the sliding support beam 5. The driven pulley 21 is arranged at the left end of the fixed support beam 4 and the right end of the sliding support beam 5. The left and right driven pulleys 21 are respectively connected to the left and right sides of the conveyor belt 22, that is, a conveyor belt 22 is arranged on the front and rear sides of the conveying equipment. A fixed block 24 is arranged on the outside of the conveyor belt 22. The fixed block 24 is rotated away from the side of the conveyor belt 22 to connect the end of the scraper 25. A guide assembly 26 is arranged above the left end of the fixed support beam 4. When the scraper 25 moves along the conveyor belt 22, the guide assembly 26 is arranged. When rotating clockwise, when the scraper 25 is located below the fixed support beam 4, the scraper 25 is in a vertical downward position due to the effect of gravity. After the scraper 25 moves to the left end of the fixed support beam 4 along with the conveyor belt 22, the scraper 25 will deflect along the inner wall of the guide assembly 26. At this time, the scraper 25 will deflect toward the material guide plate 11. At this time, the scraper 25 will fall on the material guide plate 11, thereby achieving the effect of scraping materials. In addition, both the front and rear scrapers 25 will fall on the material guide plate 11, and the ends of the front and rear scrapers 25 will be close to each other, thereby pushing the movement of materials through the scraper 25.

[0030] In one case of this embodiment, columns 14 are vertically arranged on both the front and rear sides of the left end of the base 1, the upper end of the column 14 is rotatably connected to the left end of the fixed support beam 4, and an inclination adjustment component 20 is arranged in the middle of the upper surface of the base 1, and the inclination adjustment component 20 can push the fixed support beam 4 to deflect around the upper end of the column 14. The inclination adjustment assembly 20 includes a fixed plate 17 arranged in the middle of the upper surface of the base 1, the fixed plate 17 is rotatably connected to the left and right sides of the deflection screw rod 18 arranged in the left and right directions, and a U-shaped push-pull frame 16 is threadedly connected to the middle part of the deflection screw rod 18, the U-shaped push-pull frame 16 is a U-shaped structure opening to the right, and can avoid the subsequent rotation drive assembly 23 through the notch in the middle, and walking wheels 15 are arranged on the front and rear sides of the lower surface of the U-shaped push-pull frame 16, the walking wheels 15 can roll on the upper surface of the base 1, so that the U-shaped push-pull frame 16 is transferred to the base 1 through the walking wheels 15, and the front and rear sides of the upper surface of the U-shaped push-pull frame 16 are rotatably connected to the lower end of the top plate 19, the upper end of the top plate 19 is rotatably connected to the middle part of the lower surface of the fixed support beam 4, and the top plate 19 is in a state facing the upper left, so when the U-shaped push-pull frame 16 moves left and right, the U-shaped push-pull frame 16 can drive the fixed support beam 4 to deflect through the top plate 19.

[0031] In one case of the present embodiment, a bearing seat 8 is arranged on the right side of the side of the sliding support beam 5, and the bearing seat 8 is rotatably connected to a transverse screw rod 7 arranged parallel to the sliding support beam 5, and the left side of the transverse screw rod 7 is threadedly connected to a threaded sleeve 6 fixedly connected to the fixed support beam 4. When the transverse screw rod 7 rotates, the transverse screw rod 7 will gradually screw in or out of the threaded sleeve 6, so the sliding support beam 5 can be driven to insert or withdraw from the fixed support beam 4 by the rotation of the transverse screw rod 7, thereby adjusting the total length of the fixed support beam 4 and the sliding support beam 5, thereby changing the conveying distance of the entire conveying equipment, and in order to maintain the tension state of the conveyor belt 22, a rotating drive assembly 23 is arranged on the right side of the upper surface of the base 1. The rotating drive assembly 23 includes a rotating seat 13 arranged at the right end of the upper surface of the base 1, the rotating seat 13 is rotatably connected to the lower end of the deflection beam 27, the deflection beam 27 is in a state facing the upper right, the upper end of the deflection beam 27 is fixedly connected to the U-shaped mounting frame 28, the U-shaped mounting frame 28 is a U-shaped structure with an opening upward, and the upper end of the U-shaped mounting frame 28 is rotatably connected to a driving rod 33 arranged in a front-to-back direction, and driving pulleys 34 are arranged at the front and rear ends of the driving rod 33, and the driving pulley 34 supports the conveyor belt 22, so that the conveyor belt 22 is driven to rotate through the driving pulley 34, and under the gravity Under the action of, the deflection beam 27 will have a tendency to rotate clockwise, so that the conveyor belt 22 remains in a tensioned state. A drive motor 29 is arranged on the U-shaped mounting frame 28. The output shaft of the drive motor 29 is fixedly connected to the first pulley 30. The first pulley 30 is connected to the second pulley 32 through a synchronous belt 31. The second pulley 32 is fixedly connected to the middle part of the drive rod 33. Therefore, the drive motor 29 rotates the drive rod 33 through the belt transmission process, thereby realizing the clockwise rotation of the conveyor belt 22, and the drive motor 29 also increases the gravity on the entire deflection beam 27.

[0032] In one case of the present embodiment, the cross-section of the guide plate 11 is a U-shaped structure, so that when the mullite sand falls on the guide plate 11, the mullite sand will not slide off from the front and rear sides of the guide plate 11, and a front-to-rear transverse plate 41 is fixedly connected to the right end of the fixed support beam 4, and support rollers 12 are arranged on the front and rear sides of the upper surface of the transverse plate 41. The lower left surface of the right guide plate 11 will fall on the support roller 12, and the overlapping parts of the two guide plates 11 are supported by the support roller 12, so that the two guide plates 11 can better support the mullite sand, thereby effectively completing the material guiding effect of the mullite sand.

[0033] In one case of the present embodiment, a slot 35 is provided on the side of the fixed block 24 away from the conveyor belt 22, the top of the slot 35 and the side close to the guide plate 11 are open, a rotating head 36 is provided inside the slot 35, the rotating head 36 is rotatably connected to the end of the scraper 25, and the slot 35 limits the rotation angle of the scraper 25, so the scraper 25 can only rotate from a state of being in contact with the guide plate 11 to a state perpendicular to the fixed block 24.

[0034] In one case of the present embodiment, the guide assembly 26 includes an extension frame 37 arranged on the left side of the fixed support beam 4, and an arc-shaped guide plate 38 is arranged on the upper end of the extension frame 37. When the scraper 25 moves with the conveyor belt 22, when the scraper 25 contacts the arc-shaped guide plate 38, the scraper 25 deflects toward the direction close to the guide plate 11, and a triangular guide plate 39 is arranged at one end of the sliding support beam 5 away from the fixed support beam 4. When the scraper 25 moves with the conveyor belt 22, when the scraper 25 contacts the triangular guide plate 39, the scraper 25 deflects toward the direction away from the guide plate 11. That is to say, when the scraper 25 rotates clockwise with the conveyor belt 22, after the scraper 25 moves to the left end of the fixed support beam 4, the scraper 25 will rotate to fall on the guide plate 11 under the action of the arc guide plate 38, and when the scraper 25 moves to the right end of the sliding support beam 5, the scraper 25 is lifted up by the triangular guide plate 39, so that the scraper 25 rotates to a state vertical to the fixed block 24 and thus separates from the guide plate 11. And the guide plate 11 on the right side is set to extend to the right side, so that the material can be easily separated from the guide plate 11.

[0035] In one case of this embodiment, legs 40 are provided at the left and right ends of the base 1, and the entire conveying equipment can be supported by the legs 40. In addition, since the contact area can be reduced by the legs 40, the base 1 can be stably placed in some locations with uneven ground. The leveling effect can also be achieved by adjusting the angle of the legs 40.

[0036] During the implementation of this embodiment, the total length of the fixed support beam 4 and the sliding support beam 5 is first adjusted according to the height of the target position to be transported, and the relative positions of the sliding support beam 5 and the fixed support beam 4, that is, the total length of the two material guide plates 11, are adjusted by rotating the transverse screw rod 7. After the conveying length adjustment is completed, the inclination angle of the fixed support beam 4 is adjusted, and the U-shaped push-pull frame 16 drives the fixed support beam 4 to rotate through the top plate 19 by rotating the deflection screw rod 18, thereby realizing the angle adjustment of the fixed support beam 4, so that the right end of the right material guide plate 11 is above the target position where the material needs to be transported. At this time, the preparation work of the entire conveying equipment is completed.

[0037] Start the drive motor 29, which drives the drive rod 33 to rotate through the belt transmission, so that the conveyor belt 22 rotates, and the scraper 25 rotates clockwise with the conveyor belt 22. After the scraper 25 moves above the guide plate 11, it will fall on the guide plate 11. Therefore, the operator can continuously pour the mullite sand to be transported on the left guide plate 11. After the mullite sand falls on the guide plate 11, the scraper 25 will continuously push the mullite sand to move to the upper right along the guide plate 11, and finally the mullite sand will fall at the right end of the guide plate 11, thereby achieving the conveying effect of the mullite sand.

[0038] The present invention is applicable to a mullite sand conveying device, which drives a scraper 25 to move along a guide plate 11 through a conveyor belt 22, so that the conveying length and angle of the two guide plates 11 can be freely adjusted, and the scraper 25 can also complete the movement of the mullite sand along the guide plate 11 when the inclination angle is large, so that the conveying device can conveniently adjust the conveying length and conveying angle.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
