[0028] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0029] like Figure 1 As shown, the present invention provides a combined cleaning scraper for a conveyor, and the new combined cleaning scraper for a conveyor is specifically used to clean the materials adhered to the pipeline in the powder conveying device, so as to achieve the cleaning function; the new combined cleaning scraper for a conveyor includes a scraper group and a cleaning sheet 1, the scraper group is divided into an upper scraper group 2 and a lower scraper group 3, the upper scraper group 2 and the lower scraper group 3 are detachably assembled on the outside of a fastening component 4, the cleaning sheet 1 is installed between the upper scraper group 2 and the lower scraper group 3, and the fastening component 4 is equipped with a wire rope 5. During use, the wire rope 5 is pulled by a traction machine to move axially in the pipeline, and the scraper group and the cleaning sheet 1 move in the pipeline together with the wire rope 5 through the fastening component 4, wherein the outer diameter of the cleaning sheet 1 is greater than the inner diameter of the pipeline, so as to achieve the cleaning function of the pipeline. And it should be supplemented that the scraper group 2 and the lower scraper group 3 are respectively provided with grooves matching the fastening component 4. Specifically, in this embodiment, the cleaning sheet 1 is selected as a polyurethane cleaning sheet. In actual use, the cleaning sheet 1 can be replaced with a cleaning tool made of other materials or with other shapes on the outside according to actual needs, such as a brush with a disc-shaped inside.

[0030] Furthermore, if Figure 1 , Figure 2 As shown, the upper scraper blade group 2 is composed of two first scrapers 21 with the same structure, and the lower scraper blade group 3 is composed of two second scrapers 22 with the same structure. The cross-sections of the first scraper blade 21 and the second scraper blade 22 are both semicircular, which is conducive to the upper scraper blade group 2 and the lower scraper blade group 3 being assembled and installed on the fastening component 4 or disassembled from the fastening component 4. Therefore, when the scraper blade group or the cleaning blade is damaged, the effect of quickly replacing it can be achieved, thereby improving the working efficiency of the present invention and reducing the use cost.

[0031] Furthermore, if Figure 1 , Figure 2 As shown, an annular block 6 is fixed at the bottom of the first scraper 21, and a tenon 7 is provided at the bottom of the annular block 6. The annular block 6 is used to place the cleaning sheet 1 and limit the cleaning sheet 1. In this embodiment, the tenon 7 is L-shaped.

[0032] Furthermore, if Figure 1 , Figure 2 As shown, the second scraper blade 22 is provided with a tenon groove 8 on the top thereof which matches the tenon 7 on the annular block 6, and the tenon groove 8 is arranged in an inverted L shape, and the second scraper blade 22 is mortised with the first scraper blade 21 through the tenon groove 8 and the tenon 7, thereby achieving a fixed connection between the first scraper blade 21 and the second scraper blade 22. It should be added that, in this embodiment, after the first scraper blade 21 is mortised with the second scraper blade 22, the top surface of the second scraper blade 22 is in contact with the bottom surface of the annular block 6, that is, the distance between the bottom surface of the first scraper blade 21 and the top surface of the second scraper blade 22 is equal to the thickness of the annular block 6, and the space between the bottom surface of the first scraper blade 21 and the top surface of the second scraper blade 22 is used to place the cleaning sheet 1.

[0033] Furthermore, if Figure 1 , Figure 2 As shown, an annular groove 10 for placing the clamping spring 9 is provided at the bottom of the second scraper blade 22, and the two second scrapers 22 are fixedly connected by the clamping spring 9 combination.

[0034] Furthermore, if Figure 1 , Figure 2 , Figure 3 As shown, the cleaning sheet 1 is sleeved on the annular block 6. It should be noted that the thickness of the cleaning sheet 1 is equal to or greater than the height of the annular block 6, so that after the first scraper 21 and the second scraper 22 are combined, the cleaning sheet 1 can be clamped by the first scraper 21 and the second scraper 22, thereby improving the stability of the cleaning sheet 1 when working.

[0035] Furthermore, if Figure 3 , Figure 4 As shown, the fastening assembly 4 and the steel wire rope 5 are fixedly connected or detachably connected.

[0036] In the first embodiment of the present invention, the fastening assembly 4 and the steel wire rope 5 are fixedly connected. Specifically, the fastening assembly 4 uses a metal block to be fixedly mounted on the steel wire rope 5 in the form of welding, so that the connection between the fastening assembly 4 and the steel wire rope 5 is more stable, so that the scraper assembly and the cleaning sheet 1 can be applied to pipes whose inner walls are difficult to clean. It should be noted that the pitch between the fastening assemblies 4 is set according to actual conditions.

[0037] Furthermore, if Figure 4 , Figure 5As shown, in the second embodiment of the present invention, the fastening assembly 4 includes a rotatably connected male connector 41 and a female connector 42, and the male connector 41 and the female connector 42 are both provided with fixing holes for the steel wire rope 5 to pass through, and one side of the outer wall of the male connector 41 and the female connector 42 are both provided with a plurality of connecting holes 43 that penetrate through the fixing holes, and a top screw 44 is screwed into the connecting hole 43 so that the steel wire rope 5 is fixed in the male connector 41 or the female connector 42.

[0038] Furthermore, if Figure 4 , Figure 5 , Figure 6 As shown, one end of the female connector 42 is provided with a fixing groove 45, and one end of the male connector 41 is inserted into the fixing groove 45 and is detachably connected to the female connector 42 through a second retaining ring 46. Specifically, the fixing groove 45 is provided at the bottom end of the female connector 42, and a second annular retaining groove 451 is provided on the side wall of the fixing groove 45, and a connecting hole 43 is provided on the top of the female connector 42. The male connector 41 includes a fixing end 411 and a connecting end 412, and the fixing end 411 is inserted into the fixing groove 45, and a connecting hole 43 is provided on the connecting end 412. When the fixing end 411 is inserted into the fixing groove 45, the top surface of the second annular retaining groove 451 and the bottom surface of the fixing end 411 are in the same plane, and at this time, the second retaining ring 46 is fixed in the fixing groove 45, so that the fixing end 411 can be fixed in the fixing groove 45, that is, the male connector 41 and the female connector 42 are fixedly connected. Thus, the male connector 41 and the female connector 42 can rotate freely 360° relative to each other, effectively preventing the wire rope 5 from twisting and winding during use, thereby affecting the strength of the wire rope 5. In addition, the fixed end 411 is columnar, and the outer diameter of the fixed end 411 matches the inner diameter of the fixed groove 45. The columnar design of the fixed end 411 allows the male connector 41 and the female connector 42 to rotate freely in the horizontal direction.

[0039] In addition, it should be noted that the depth of the fixing groove 45 is greater than the thickness of the fixing end 411, and the outer diameter of the connecting end 412 is smaller than the outer diameter of the fixing end 411, so that there is a free space between the connecting end 412 and the side wall of the fixing groove 45 for the second clamping spring 46 to be installed or removed. At the same time, the fixing holes of the connecting male head 41 and the connecting female head 42 are coaxially arranged. This ensures that the force between the connecting male head 41 and the connecting female head 42 is more uniform when there is a tensile force, that is, the connection is more stable.

[0040] In the second embodiment of the present invention, the fastening assembly 4 and the steel wire rope 5 are detachably connected, and the fastening assembly 4 can be used to connect the joints of the two steel wire ropes 5, thereby extending the length of the overall conveying chain of the steel wire rope 5. Specifically, during use, the first steel wire rope joint is fixed in the fixing hole of the connecting female head 42 through the top wire 44, and the second steel wire rope joint is fixed in the fixing hole of the connecting male head 41 through the top wire 44, and then the connecting female head 42 and the connecting male head 41 are connected through the second retaining spring 46, so as to realize the fixed connection between the first steel wire rope and the second steel wire rope. In this embodiment, the connecting male head 41 and the connecting female head 42 are each provided with two connecting holes 43, and the axes of the two connecting holes 43 are parallel to each other, so as to facilitate the installation and disassembly of the staff. In this embodiment, the fastening assembly 4 can also act on a single steel wire rope 5, that is, the connecting female head 42 and the connecting male head 41 can be directly mounted on the same steel wire rope 5 in sequence or assembled, and then moved to a designated position and fixed by the top wire 44. Since the fastening assembly 4 and the steel wire rope 5 are detachably connected, when the fastening assembly 4 acts on the single steel wire rope 5, the distance between adjacent fastening assemblies 4 can be adjusted according to actual conditions, that is, the distance between adjacent cleaning sheets 1 can be adjusted, so that the present invention can be applied to the cleaning needs of various pipelines, thereby improving the applicability of the present invention.

[0041] Furthermore, if Figure 3 , Figure 4 As shown, the fastening assembly 4 is provided with an I-shaped structure for preventing the scraper assembly from axially moving.

[0042] Specifically, in the first embodiment of the present invention, the fastening assembly 4 is an I-shaped metal block, the outer diameters of the top and bottom ends of the I-shaped metal block are larger than the outer diameter of the middle part, and the scraper assembly is sleeved in the middle part of the I-shaped metal block, so that the top and bottom ends of the I-shaped metal block limit the scraper assembly to prevent it from axially moving relative to the I-shaped metal block. It should be added that after the scraper assembly is assembled, the thickness at the axis is equal to the distance from the bottom surface of the top end of the I-shaped metal block to the top surface of the bottom end, and the inner diameter of the annular clamping block 6 and the inner diameter of the cleaning sheet 1 are larger than the outer diameters of the top and bottom ends of the I-shaped metal block, thereby ensuring that the cleaning sheet 1 can move normally on the steel wire rope 5 sleeved with the I-shaped metal block.

[0043] In the second embodiment of the present invention, the female connector 42 is an I-shaped connector. Specifically, an end cap is fixed above the top of the female connector 42. The outer diameter of the end cap and the outer diameter of the bottom of the female connector 42 are both larger than the outer diameter of the top of the female connector 42. The top of the female connector 42 is the belly column part of the I-shaped structure. The upper scraper group 2 is assembled and mounted on the top of the female connector 42 and partially mounted on one end of the bottom of the female connector 42. The upper scraper group 2 is provided with a groove that matches the female connector 42. The lower scraper group 3 is assembled and mounted on the connection end 412 of the male connector 41 and partially mounted on the other end of the bottom of the female connector 42. The lower scraper group 3 is provided with a groove that matches the female connector 42 and the male connector 41. Based on the restrictions of the upper end cap and the bottom of the female connector 42, the scraper group cannot have relative axial movement with the female connector 42 or the male connector 41, thereby realizing the limiting function of the fastening assembly 4.

[0044] The installation process of the present invention is as follows:

[0045] First, the fastening assembly 4 is fixed on the steel wire 5, and then the first scraper 21 is assembled and mounted on the fastening assembly 4, and then the cleaning sheet 1 is mounted on the annular block 6 of the first scraper 21, and then the two second scrapers 22 are respectively mortised with the first scraper 21 in sequence to form a complete scraper shape, and finally the clamping spring 9 is clamped in the annular clamping groove 10 on the second scraper 22 to achieve fixed connection between the second scrapers 22, between the second scraper 22 and the first scraper 21, and between the first scrapers 21. When the cleaning sheet 1 is damaged, the cleaning sheet 1 can be disassembled and assembled by simply removing the clamping spring 9 and the second scraper 22, thereby effectively improving work efficiency.

[0046] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
