Description

An adjustable leveling device for mixing raw materials Technical Field

[0001] This invention relates to the field of raw material conveying technology, specifically to an adjustable leveling device for raw material mixing. Background Technology

[0002] Raw material conveying is mainly used for horizontal and inclined conveying of bulk materials. Belt conveyors have the advantages of long conveying distance, large conveying capacity, fast conveying speed and low transportation cost. They are also easy to maintain and are energy-saving and environmentally friendly. When conveying raw materials, the raw materials need to be spread and mixed. The raw materials are sent into the equipment for further processing along the conveyor belt.

[0003] In existing technologies, the raw materials on the surface of the conveyor belt need to be leveled before being fed into the next step of the equipment. However, this is done manually, which is inefficient. When people use tools to level the raw materials on the conveyor belt, the tools are prone to colliding with the conveyor. Furthermore, the leveling thickness is uneven, resulting in poor processing of the raw materials after they are fed into the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable leveling device for mixing raw materials, so as to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0008] As a preferred embodiment of the present invention, the two ends of the stirring fork are threadedly connected to the inner wall of the rotating cylinder, and a row of flipping forks is provided in the middle of the stirring fork, and the two ends of the spreading plate are threadedly connected to the inner wall of the gear set.

[0009] As a preferred technical solution of the present invention, an adjustment structure is provided at the intersection of the upper end of the conveyor and the fixed block. The adjustment structure includes four fixed slots and four drive motors are provided at the four corners of the fixed block. Each of the two fixed slots is provided with a telescopic spring. The end of the telescopic spring is connected to a rack, and the rack is located inside the fixed slot and the reserved slot. The side wall of the reserved slot is provided with an adjustment tooth corresponding to the rack. The control structure is located on one side of one of the racks.

[0010] As a preferred embodiment of the present invention, there is a gap between the fixed groove and the reserved groove, and the gap between the fixed groove and the reserved groove is greater than the thickness of the rack, and the length of the first telescopic spring is greater than the gap between the fixed groove and the reserved groove.

[0011] In a preferred embodiment of the present invention, two of the fixed slots are slidably connected to the reserved slots, and the racks of the other two fixed slots are engaged with the adjusting teeth of the reserved slots.

[0012] As a preferred embodiment of the present invention, the control structure includes a rotating sleeve composed of an inner ring and an outer ring. The rotating sleeve is disposed between the second drive motor and the first rotating shaft. The two ends of the rotating sleeve are respectively provided with a first mating groove and a second mating groove. A mating block is welded to the end of the first rotating shaft and located inside the first mating groove. The mating block of the first rotating shaft is slidably connected to the first mating groove. The output end of the second drive motor is slidably connected to the second mating groove of the rotating sleeve.

[0013] In a preferred embodiment of the present invention, the depth of the first mating groove of the rotating sleeve is twice the depth of the second mating groove, and the depth of the first mating groove is greater than the thickness of the second mating groove.

[0014] As a preferred technical solution of the present invention, a wedge plate is slidably connected inside the fixed block and on one side of the rack, and a wedge block is welded to one side of the rotating sleeve, and the wedge block and the wedge plate are slidably connected.

The distance between the flat plate and the mixing fork of the paving structure and the conveyor belt can be adjusted, and the thickness of the raw material on the surface of the conveyor belt can be adjusted.

[0019] 3. It is equipped with a control structure. The rotating sleeve connects the second drive motor and the first rotating shaft, which can compensate for the gap between the second drive motor and the first rotating shaft and ensure that the leveling structure can operate normally.

[0020] 4. The adjustment and control structures work together. When the two racks are brought closer to the middle of the fixed block, the wedge plate and wedge block can slide. When the fixed block is lifted, the leveling structure will stop rotating. When adjusting the height of the leveling structure, the material on the conveyor belt surface will not be disturbed. The fixed block will not affect the operation of the leveling structure after it is in place. Attached Figure Description

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please refer to Figures 1-4. An adjustable leveling device for raw material mixing includes a conveyor 1, a conveyor belt 2, and a drive motor 3. The conveyor belt 2 is located in the middle of the conveyor 1, and the drive motor 3 is located on one side of the conveyor 1. Both ends of the conveyor belt 2 are equipped with rollers, and the output end of the drive motor 3 is connected to the rollers, so that the drive motor 3 can drive the conveyor belt 2 to rotate, thereby mixing the raw materials on the surface of the conveyor belt 2. Reserved slots 4 are opened on the upper sides of both sides of the conveyor 1. A fixing block 5 is installed inside the reserved slot 4 and above the conveyor belt 2. The fixing block 5 is clamped in the reserved slot 4 of the conveyor 1. A leveling structure 6 is provided inside the fixing block 5 and near the conveyor belt 2. The leveling structure 6 includes a drive motor 61, which is located on one side of the fixing block 5 and fixed to the side wall of the fixing block 5. The fixing block 5 is equipped with a rotating shaft 62 and a rotating shaft 66. The output end of the drive motor 61 is connected to the rotating shaft 66 through a control structure 8. A rotating shaft 62 is connected to a drive motor 61, the output end of which is connected to the rotating shaft 62. A gear set 64, meshing sequentially, is provided between the same ends of the rotating shaft 62 and the rotating shaft 66. The rotating shaft 62 is driven by the gear set 64 to drive the rotating shaft 66. A rotating cylinder 63 and a rotating cylinder 65 are respectively fitted onto the rotating shaft 62 and the rotating shaft 66. The rotating cylinders 63 and 65 rotate synchronously. The rotating shaft 62 drives the rotating cylinder 63 to rotate, and the rotating shaft 66 drives the rotating cylinder... The first rotating cylinder 63 and the second rotating cylinder 65 are respectively equipped with a stirring fork 68 and a spreading plate 67, and the spreading plate 67 and the stirring fork 68 are located directly above the conveyor belt 2. The first rotating cylinder 63 rotates with the stirring fork 68, and the second rotating cylinder 65 drives the spreading plate 67 to rotate. First, the stirring fork 68 turns and stirs the raw material on the conveyor belt 2, and then the spreading plate 67 of the second rotating cylinder 65 spreads the stirred raw material flat. The flattened raw material is then transported by the conveyor belt 2 to the next process.

[0035] Please refer to Figures 4 and 5. The gear set 64 consists of three gears, which mesh sequentially. The first rotating cylinder 63 and the second rotating cylinder 65 rotate in the same direction. The first rotating shaft 62 drives the second rotating shaft 66 to rotate through the gear set 64, so that both the first rotating cylinder 63 and the second rotating cylinder 65 can rotate. The stirring fork 68 of the first rotating cylinder 63 and the spreading plate 67 of the second rotating cylinder 65 spread the raw material evenly, thereby spreading and transporting the material on the conveyor belt 2 to the designated position. The spreading plate 67 and the stirring fork 68 are in continuous contact with the surface of the conveyor belt 2, which can evenly spread the raw material on the surface of the conveyor belt 2.

[0036] Please refer to Figures 4-6. The two ends of the stirring fork 68 are threaded to the inner wall of the rotating cylinder 63, and a row of flipping forks is provided in the middle of the stirring fork 68. The two ends of the spreading plate 67 are threaded to the inner wall of the gear set 64. By connecting the stirring fork 68 and the spreading plate 67 through threads, the angle of the spreading plate 67 and the stirring fork 68 can be adjusted, so that the spreading plate 67 and the stirring fork 68 can come into contact with the surface material of the conveyor belt 2.

[0037] Example 2:

[0038] Please refer to Figures 3 and 7. An adjustment structure 7 is provided at the intersection of the upper end of the conveyor 1 and the fixed block 5. The adjustment structure 7 includes four fixed slots 71, and four drive motors 61 are located at the four corners of the fixed block 5. A reserved slot 4 can be slidably connected to the drive motors 61, allowing the fixed block 5 to be placed in the reserved slot 4. Two of the fixed slots 71 are equipped with telescopic springs 74, and the ends of the telescopic springs 74 are connected to racks 73. The racks 73 are located between the fixed slots 71 and the reserved slots 4. Inside, the side wall of the reserved groove 4 is provided with an adjusting tooth 72 corresponding to the rack 73. The control structure 8 is located on one side of one of the racks 73. By moving two racks 73 closer to the middle, the racks 73 can be put into the reserved groove 4. Under the action of the telescopic spring 74, the racks 73 and the adjusting tooth 72 are locked together. The positions of the racks 73 and the adjusting tooth 72 can also be adjusted, thereby moving the leveling structure 6 of the fixing block 5 up and down. Adjusting the height of the leveling structure 6 can adjust the thickness of the raw material on the conveyor belt 2.

[0039] In this embodiment, there is a gap between the fixed groove 71 and the reserved groove 4, and the gap between the fixed groove 71 and the reserved groove 4 is greater than the thickness of the rack 73. The length of the telescopic spring 74 is greater than the gap between the fixed groove 71 and the reserved groove 4. The rack 73 is inside the reserved groove 4. Two of the fixed grooves 71 are slidably connected to the reserved groove 4. The racks 73 of the other two fixed grooves 71 are engaged with the adjusting teeth 72 of the reserved groove 4, thereby moving the fixed block 5 up and down along the reserved groove 4. After the adjusting teeth 72 and the racks 73 are engaged, the fixed block 5 can be fixed. After adjusting the position of the leveling structure 6, the raw material on the upper surface of the conveyor belt 2 can be leveled. The distance between the spreading plate 67 and the stirring fork 68 of the leveling structure 6 and the conveyor belt 2 can be adjusted, and the thickness of the raw material on the surface of the conveyor belt 2 can be adjusted.

[0040] Example 3:

[0041] Please refer to Figures 3 and 8. The control structure 8 includes a rotating sleeve 83 composed of an inner ring and an outer ring. The rotating sleeve 83 is disposed between the second drive motor 61 and the first rotating shaft 62. The wedge plate 81 drives the rotating sleeve 83 and the wedge block 82 to rotate. The two ends of the rotating sleeve 83 are respectively provided with a first mating groove 86 and a second mating groove 88. The end of the first rotating shaft 62 and the interior of the first mating groove 86 are welded with a mating block 87. The mating block 87 of the first rotating shaft 62 and the first mating groove 86 are slidably connected. The output end of the second drive motor 61 is slidably connected with the second mating groove 88 of the rotating sleeve 83. The end of the second drive motor 61 and the mating block 87 are located inside the stirring fork 68 and the second rotating shaft 66. When the second drive motor 61 rotates, it can rotate the first rotating shaft 62.

[0042] Please refer to Figures 8 and 9. The depth of the first mating groove 86 of the rotating sleeve 83 is twice the depth of the second mating groove 88, and the depth of the first mating groove 86 is greater than the thickness of the second mating groove 88. The rotating sleeve 83 can be slid along the direction of the first rotating shaft 62 and disengage from the second mating groove 88.

[0043] In this embodiment, a wedge plate 81 is slidably connected inside the fixed block 5 and on one side of the rack 73. A wedge block 82 is welded to one side of the rotating sleeve 83, and the wedge block 82 and the wedge plate 81 are slidably connected. A guide pin 84 and a telescopic spring 85 are provided inside the fixed block 5 and at the wedge block 82. The telescopic spring 85 is sleeved on the outside of the guide pin 84, and the guide pin 84 is slidably connected to the wedge block 82. Each time the fixed block 5 is lifted or lowered, the wedge plate 81 can be moved toward the wedge block 82, and the rotating sleeve 83 can be moved toward the rotating shaft 62. The mating groove 88 of the rotating sleeve 83 can be disengaged from the end of the drive motor 61.

[0044] Please refer to Figure 9. The direction of the guide pin 84 is parallel to the direction of the rotating shaft 62, and the sliding distance of the wedge block 82 is greater than the depth of the mating groove 88. The extension spring 85 can move the wedge block 82, so that the wedge plate 81 and the wedge block 82 can be reset when the rack 73 is released. When the two racks 73 are brought closer to the middle of the fixed block 5, the wedge plate 81 and the wedge block 82 can be slid. When the fixed block 5 is lifted, it will ensure that the leveling structure 6 stops rotating. When adjusting the height of the leveling structure 6, the material on the surface of the conveyor belt 2 will not be disturbed. After the fixed block 5 is placed, it will not affect the operation of the leveling structure 6.

[0045] In use, the raw materials to be conveyed by the conveyor 1 are placed on the surface of the conveyor belt 2, and the conveyor belt 2 is rotated by the drive motor 3 and the roller, so that the raw materials are conveyed to the designated place. During this process, the raw materials on the conveyor belt 2 need to be flattened. At this time, the flattening structure 6 inside the fixed block 5 operates to flatten the raw materials. Specifically, the drive motor 61 is started, which drives the rotating sleeve 83 and the rotating shaft 62 to rotate. The gear set 64 between the ends of the rotating shaft 62 and the rotating shaft 66 meshes with each other, so that the rotating shaft 62 and the rotating shaft 66 rotate synchronously. The rotating cylinder 63 and the rotating cylinder 65 also rotate simultaneously. At this time, the stirring fork 68 of the rotating cylinder 63 stirs and turns the raw materials, and the rotating cylinder 65 of the rotating shaft 66 flattens the stirred and turned raw materials, so that the raw materials on the surface of the conveyor belt 2 are turned and flattened, thus ensuring that the raw materials on the surface of the conveyor belt 2 can be evenly covered. There is no need for manual flattening of the raw materials on the surface of the conveyor belt 2, which is more convenient and efficient.

[0046] Because different raw materials will result in different thicknesses of raw materials laid on the surface of conveyor belt 2, it is necessary to change the distance between the mixing fork 68 and the spreading plate 67 and the conveyor belt 2. Specifically, the fixing block 5 is moved up and down along the inside of the reserved groove 4, so that the fixing grooves 71 at the two corners of the fixing block 5 are slidably connected to the reserved groove 4. The other two racks 73 are locked with the adjusting teeth 72, so that the racks 73 and the adjusting teeth 72 fix the fixing block 5 at the reserved groove 4. At this time, the distance between the mixing fork 68 and the spreading plate 67 of the spreading structure 6 and the conveyor belt 2 is adjusted to a suitable height. At this time, the mixing fork 68 and the spreading plate 67 can spread the raw materials to a suitable thickness.

[0047] When the leveling structure 6 inside the fixed block 5 is raised or lowered, the stirring fork 68 and the spreading plate 67 need to be stopped from rotating. At this time, the drive motor 61 and the rotating shaft 62 can be controlled by the control structure 8. Specifically, the two racks 73 are moved closer to the middle of the fixed block 5, so that the racks 73 push the wedge plate 81 to move. The wedge plate 81 and the wedge block 82 are slidably connected. The wedge block 82 moves along the guide pin 84. The mating groove 86 of the rotating sleeve 83 is slidably connected to the mating block 87, so that the mating block 87 disengages from the rotating sleeve 83 and the mating groove 86. Thus, when the fixed block 5 is raised or lowered, the rotating sleeve 83 disengages from the end of the drive motor 61, so that the rotating cylinder 63 and the rotating cylinder 65 stop rotating. When the fixed block 5 is lifted, the leveling structure 6 will not... As the rotation continues, when the rack 73 of the fixing block 5 is placed inside the reserved slot 4 again, the rack 73 moves at the fixing slot 71 under the action of the first telescopic spring 74. The wedge plate 81 will not be pressed against by the rack 73, and under the action of the second telescopic spring 85 of the guide pin 84, the wedge block 82 will be pushed to move. The wedge block 82 will push the wedge plate 81 to move, so that the wedge plate 81 moves away from the rotating sleeve 83. Thus, the second mating slot 88 of the rotating sleeve 83 will re-mate with the end of the second drive motor 61, so that the inner ring of the rotating sleeve 83 drives the mating block 87 to rotate. The wedge block 82 moves along the guide pin 84, so that the inner and outer rings of the rotating sleeve 83 rotate relative to each other, so that the second drive motor 61 can drive the first rotating shaft 62 to rotate again.

[0048] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
