[0024] 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.

[0025] Please see Figure 1-6 One embodiment provided by this utility model:

[0026] A screw conveyor for rock asphalt production, comprising:

[0027] The machine body includes a conveying trough 1, which is used to place rock asphalt and convey it. A support plate 11 is fixedly connected to the outer surface of the conveying trough 1. The support plate 11 is used to support a drive motor 12. The upper surface of the support plate 11 is fixedly connected to the drive motor 12. The drive motor 12 is used to drive the rotating shaft 27 and the spiral blade 28 to rotate, thereby conveying the rock asphalt. The drive motor 12 is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here.

[0028] The disassembly mechanism includes a mounting base 2, which is fixedly connected to the output shaft of the drive motor 12. The mounting base 2 is used to mount the rotating shaft 27 and the helical blade 28 onto the output shaft of the drive motor 12, allowing the drive motor 12 to drive the rotating shaft 27 and the helical blade 28 to rotate. A limit ring 21 is rotatably connected inside the mounting base 2, limiting the bidirectional lead screw 22 so that it can only rotate in place. The surface of the limit ring 21 is fixedly connected to the bidirectional lead screw 22, which drives two sets of moving plates 24 to move two sets of insert rods 25 away from each other, causing the two sets of insert rods 25 to detach from the first mounting block 26. This allows for the disassembly of the rotating shaft 27 and the helical blade 28, facilitating the cleaning of rock asphalt adhering to the rotating shaft 27 and the helical blade 28, as well as inside the conveying trough 1, thus benefiting the use of the screw conveyor. A rotating head 23 is fixedly connected to the surface of the bidirectional lead screw 22, which facilitates the cleaning of rock asphalt adhering to the rotating shaft 27 and the helical blade 28, as well as inside the conveying trough 1. The operator rotates the bidirectional lead screw 22, and a movable plate 24 is movably connected to the surface of the bidirectional lead screw 22. The movable plate 24 is used to drive the two sets of insert rods 25 away from each other, so that the two sets of insert rods 25 are detached from the first mounting block 26, thereby enabling the disassembly of the rotating shaft 27 and the spiral blade 28. The insert rod 25 is fixedly connected to the surface of the movable plate 24. The insert rod 25 is used to insert into the first mounting block 26, so that the rotating shaft 27 and the spiral blade 28 can be installed on the mounting base 2. The first mounting block 26 is movably connected to the surface of the insert rod 25. The first mounting block 26 is used to install the rotating shaft 27 and the spiral blade 28 on the mounting base 2. The cross-section of the first mounting block 26 is smaller than the cross-section of the rotating shaft 27, so that the rotating shaft 27 and the spiral blade 28 can be pulled out to the side when disassembling the rotating shaft 27 and the spiral blade 28. The rotating shaft 27 and the spiral blade 28 are used to transport rock asphalt.

[0029] Furthermore, the folding mechanism includes a second mounting block 3 and a second positioning plate 34. The second mounting block 3 is fixedly connected to the lower surface of the conveying trough 1 and is used to mount the support leg 31 on the conveying trough 1. The second positioning plate 34 is fixedly connected to the lower surface of the conveying trough 1. The support leg 31 is hinged to the surface of the second mounting block 3 and is used to support the conveying trough 1. The first positioning plate 32 is fixedly connected to the surface of the support leg 31. The first bolt 33 is threadedly connected to the surface of the second mounting block 3. The first positioning plate 32 and the first bolt 33 are used to position the support leg 31 when it is not folded. The second bolt 35 is threadedly connected to the surface of the second positioning plate 34. The second positioning plate 34 and the second bolt 35 are used to position the support leg 31 when it is folded, thereby realizing the folding of the support leg 31, thereby reducing the volume of the device and facilitating the storage and transportation of the device.

[0030] Furthermore, the mounting base 2 is rotatably connected to the conveying trough 1 via the drive motor 12. The mounting base 2 is used to mount the rotating shaft 27 and the spiral blade 28 on the output shaft of the drive motor 12, so that the drive motor 12 can drive the rotating shaft 27 and the spiral blade 28 to rotate. The limiting ring 21 is circular and is used to limit the bidirectional screw 22, so that the bidirectional screw 22 can only rotate in place. The bidirectional screw 22 is rotatably connected to the mounting base 2 via the limiting ring 21. The bidirectional screw 22 is used to drive the two sets of moving plates 24 to move the two sets of insert rods 25 away from each other, so that the two sets of insert rods 25 are separated from the first mounting block 26, thereby enabling the disassembly of the rotating shaft 27 and the spiral blade 28. This facilitates the cleaning of rock asphalt adhering to the rotating shaft 27 and the spiral blade 28 and inside the conveying trough 1 by the staff, which is beneficial to the use of the screw conveyor.

[0031] Furthermore, the rotating head 23 is used to facilitate the rotation of the bidirectional lead screw 22 by the operator. The moving plate 24 is distributed in two groups on the surface of the bidirectional lead screw 22. The moving plate 24 is slidably connected to the mounting base 2 through the bidirectional lead screw 22. The moving plate 24 is used to drive the two sets of insert rods 25 away from each other, so that the two sets of insert rods 25 are detached from the first mounting block 26, thereby enabling the disassembly of the rotating shaft 27 and the spiral blade 28. The insert rod 25 is connected to the first mounting block 26 through the moving plate 24. The insert rod 25 is used to insert into the first mounting block 26, thereby enabling the rotating shaft 27 and the spiral blade 28 to be mounted on the mounting base 2.

[0032] Furthermore, the first mounting block 26 is movably connected to the mounting base 2 via the insertion rod 25, and the rotating shaft 27 is movably connected to the mounting base 2 via the first mounting block 26. The cross-section of the first mounting block 26 is smaller than the cross-section of the rotating shaft 27. The first mounting block 26 is used to mount the rotating shaft 27 and the spiral blade 28 on the mounting base 2. The cross-section of the first mounting block 26 is smaller than the cross-section of the rotating shaft 27, so that the rotating shaft 27 and the spiral blade 28 can be pulled out to the side when disassembling them. The rotating shaft 27 and the spiral blade 28 are rotatably connected to the conveying trough 1 via the mounting base 2. The rotating shaft 27 and the spiral blade 28 are used to convey rock asphalt.

[0033] Furthermore, the second mounting blocks 3 are symmetrically distributed in four groups on the lower surface of the conveying trough 1. The second mounting blocks 3 are used to mount the support legs 31 on the conveying trough 1. The support legs 31 are used to support the conveying trough 1. The first positioning plate 32 is movably connected through the support legs 31 and the second mounting blocks 3.

[0034] Furthermore, the first bolt 33 penetrates the first positioning plate 32. The first positioning plate 32 and the first bolt 33 are used to position the support leg 31 when it is not folded. The second positioning plate 34 is symmetrically distributed in four groups on the lower surface of the conveying trough 1. The second positioning plate 34 and the second bolt 35 are used to position the support leg 31 when it is folded, thereby realizing the folding of the support leg 31, which reduces the volume of the device and makes it easier to store and transport the device.

[0035] Working principle: Rotating the rotating head 23 drives the bidirectional lead screw 22 to rotate, which in turn drives the two sets of moving plates 24 to move the two sets of insert rods 25 away from each other, so that the two sets of insert rods 25 are separated from the first mounting block 26. This allows the shaft 27 and the spiral blade 28 to be disassembled, which in turn makes it easier for workers to clean the rock asphalt adhering to the shaft 27 and the spiral blade 28 as well as the conveying trough 1, which is beneficial to the use of the screw conveyor.

[0036] Rotating the first bolt 33 to disengage it from the first positioning plate 32 allows the support leg 31 to be folded up. Then, rotating the second bolt 35 to insert it into the support leg 31 allows the support leg 31 to be positioned, thus achieving the folding of the support leg 31. This reduces the size of the device and makes it easier to store and transport.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
