Implementation

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a waterproof telescopic chute bulk loader outer bag, referring to Figure 1 and Figure 2 , including an integrally arranged wear-resistant bag 1 and a waterproof bag 2, the wear-resistant bag 1 is located on the inside, and the waterproof bag 2 is located on the outside. The wear-resistant bag 1 and the waterproof bag 2 are both woven with canvas, and a waterproof coating 3 is impregnated on the outer wall of the waterproof bag 2. Both ends of the waterproof bag 2 extend a cylindrical connecting collar 5, the end of the connecting collar 5 is folded toward the inside of the waterproof bag 2, and the waterproof coating 3 extends to one end of the connecting collar 5 folded to the inside of the waterproof bag 2 and is fixed to the inner wall of the wear-resistant bag 1 by sewing.

[0023] Reference Figure 1 and Figure 3 A clamping mechanism 4 is provided on the outer wall of the connecting collar 5. The clamping mechanism 4 includes a fixing strip 41 which is annularly wrapped around the outer wall of the connecting collar 5. The fixing strip 41 is made of stainless steel. A first connecting block 42 and a second connecting block 43 in the shape of a rectangular parallelepiped are welded on both ends of the fixing strip 41. The length direction of the first connecting block 42 and the second connecting block 43 are arranged in the length direction of the fixing strip 41. A first mounting hole 421 is coaxially penetrated on the first connecting block 42. A retaining ring 44 is integrally provided on the surface of the first connecting block 42 facing the second connecting block 43. The retaining ring 44 is coaxial with the first mounting hole 421 and is located in one end of the first mounting hole 421 facing the second mounting block 46. A second mounting hole 431 is coaxially penetrated on the second connecting block 43. A retaining ring 44 is integrally provided on the surface of the second connecting block 43 facing the first connecting block 42. The retaining ring 44 is coaxial with the second mounting hole 431 and is located in one end of the second mounting hole 431 facing the first mounting block 45.

[0024] Reference Figure 1 and Figure 3 A cylindrical first mounting block 45 is placed in the first mounting hole 421, and a second mounting block 46 is also placed in the second mounting hole 431. The opposite ends of the first mounting block 45 and the second mounting block 46 are both hemispherical. The diameter of the first mounting block 45 is smaller than the aperture of the first mounting hole 421 and larger than the inner diameter of the retaining ring 44. The diameter of the second mounting block 46 is smaller than the aperture of the second mounting hole 431 and larger than the inner diameter of the retaining ring 44. A third mounting hole 451 is coaxially formed on the first mounting block 45, and a tension bolt 47 is slidably inserted in the third mounting hole 451. One end of the tension bolt 47 coaxially penetrates the second mounting block 46 and cooperates with the second mounting expansion thread.

[0025] Reference Figure 1 and Figure 3 When the fixing strip 41 is locked by tightening the tension bolt 47, the hemispherical ends of the first mounting block 45 and the second mounting block 46 will both be pressed against the inner edge of the retaining ring 44, and then, under the push of the tension bolt 47, the first mounting block 45 and the second mounting block 46 will both rotate and adjust their positions as the two ends of the fixing strip 41 approach each other, so that the first mounting block 45 and the second mounting block 46 always remain in a coaxial state, and can apply the most appropriate tension to the two ends of the fixing strip 41. And because the tension bolt 47 is not easily subjected to radial force after being locked, the tension bolt 47 is not easy to bend, which is convenient for subsequent disassembly and installation, and at the same time improves the service life of the tension bolt 47.

[0026] Reference Figure 1 and Figure 3The ends of the first mounting block 45 and the second mounting block 46 that are away from each other extend out of the first mounting hole 421 and the second mounting hole 431 respectively, and the cross-section of the extended end of the second mounting block 46 is a regular hexagon, so it is convenient to rotate the tightening bolt 47 to tighten the fixing strip 41.

[0027] Reference Figure 1 and Figure 3 A fourth connecting hole 411 is provided on one end surface of the fixing bar 41, and a long groove 412 is provided on the inner side wall of the fixing bar 41. The long groove 412 is provided along the length direction of the fixing bar 41, and the length of the long groove 412 is the same as the depth of the fourth connecting hole 411. The long groove 412 is connected and communicated with the fourth connecting hole 411.

[0028] Reference Figure 1 and Figure 3 A connecting strip 7 is coaxially and integrally arranged on the end face of the other end of the fixing strip 41, and the connecting strip 7 is slidably matched with the fourth connecting hole 411. When the fixing strip 41 is tightened, the connecting strip 7 is slidably installed in the fourth connecting hole 411, and a tightening strip 71 is integrally arranged on a side wall of the connecting strip 7 facing the long groove 412. The tightening strip 71 is arranged along the length direction of the connecting strip 7, and the tightening strip 71 is slidably installed in the long groove 412. At the same time, a side wall of the tightening strip 71 facing away from the connecting strip 7 is flush with the inner wall of the fixing strip 41.

[0029] Reference Figure 1 and Figure 3 After the fixing strip 41 is tightened, in order to ensure that the fixing strip 41 can clamp the connecting collar 5 to the connecting port of the working equipment, the length of the fixing strip 41 will be smaller than the circumference of the connecting collar 5, so that after the fixing strip 41 is tightened, there will always be a blank part on the connecting collar 5 that is not tightened. Through the cooperation between the above-mentioned tightening strip 71, the connecting strip 7, the fourth connecting hole 411 and the long groove 412, the fixing strip 41 can tighten the connecting collar 5 to the connecting end of the working equipment while also tightening the blank part to prevent external rainwater from penetrating into the wear-resistant bag 1 from the untightened part of the connecting collar 5.

[0030] The implementation principle of the outer bag of a waterproof telescopic chute bulk loader in an embodiment of the present application is as follows: the wear-resistant bag 1 is used to correspond to the friction of the transmitted powder, and the waterproof bag 2 is used to correspond to the penetration of external rainwater, so that the present application can ensure wear resistance while external rainwater is not easy to penetrate into the wear-resistant bag 1 to cause the powder to condense into a solid.

[0031] When fixing the connecting collar 5 on the connecting port of the working equipment, first put the connecting collar 5 on the connecting port, then slide the fixing strip 41 to a suitable position, fix the second mounting block 46 with a hexagonal wrench, and then turn the tightening bolt 47 to tighten the fixing strip 41. At the same time, during the tightening process of the fixing strip 41, the connecting strip 7 needs to be aligned and slidably installed in the fourth connecting hole 411. After tightening the tightening bolt 47, the fixing of the connecting collar 5 is completed.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
