[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] The embodiment of the present application discloses an auxiliary unloading device for mining trucks. Figure 1 and Figure 2 An auxiliary unloading device for a mining truck includes an auxiliary unloading belt 1, a receiving assembly 2, a scraping assembly 3, and an unfolding assembly 4. The auxiliary unloading belt 1 is installed on the inner floor of a truck compartment 100. A second chute is defined within the inner floor of the truck compartment 100. A second slider 11 is fixed to the bottom of the auxiliary unloading belt 1 and slides within the second chute. One end of the auxiliary unloading belt 1 is connected to the receiving assembly 2, and the other end is connected to the unfolding assembly 4.

[0037] Reference Figure 1 and Figure 2 The storage assembly 2 includes a first fixed plate 21, a first storage roller 22, a first extension rod 23, a first rotating handle 24 and a first limiting screw 25. Two first fixed plates 21 are provided, and the two first fixed plates 21 are fixedly connected at the discharge port of the truck compartment 100 at an interval. The first storage roller 22 is rotatably connected between the two first fixed plates 21. One end of the auxiliary unloading belt 1 is fixedly connected to the first storage roller 22, and the auxiliary unloading belt 1 is wound around the first storage roller 22. The first extension rod 23 is fixedly connected to the end of the first storage roller 22. The first rotating handle 24 is fixedly connected to the end of the first extension rod 23 away from the first storage roller 22. The first limiting screw 25 is located at the end of the first rotating handle 24 away from the first extension rod 23. The first limiting screw 25 passes through the first rotating handle 24 and is threaded into the first fixed plate 21. Removing the first limiting screw 25 of the first rotating handle 24 releases the first storage roller 22. After the first receiving roller 22 is released, the first rotating handle 24 is rotated, and the first rotating handle 24 can drive the first extension rod 23 to rotate, thereby driving the first receiving roller 22 to rotate, so that the auxiliary unloading belt 1 in the truck compartment 100 is stored in the first receiving roller 22.

[0038] Reference Figure 1 and Figure 2 The scraper assembly 3 includes a second fixed plate 31, a scraper 32, a first slider 33, a spring 34 and a telescopic rod 35. There are two second fixed plates 31, and the two second fixed plates 31 are respectively fixedly connected to the side of the two first fixed plates 21 facing away from the truck compartment 100. A first chute is provided on the inner side of the two second fixed plates 31. The scraper 32 abuts against the surface of the auxiliary unloading belt 1. There are two first sliders 33, and the two first sliders 33 are respectively slidably connected in the two first chute. One end of the spring 34 is fixed to the side of the first slider 33, and the other end of the spring 34 is fixed to the side wall of the first chute. The telescopic rod 35 is located in the spring 34, and one end of the telescopic rod 35 is fixed to the side of the first slider 33, and the other end of the telescopic rod 35 is fixed to the side wall of the first chute. As the storage assembly 2 retracts the auxiliary unloading belt 1 within the truck compartment 100 onto the first retraction roller 22, the scraper 32 abuts against the auxiliary unloading belt 1, scraping away the mineral powder on the auxiliary unloading belt 1. This reduces the amount of mineral powder remaining within the truck compartment 100 and improves the truck's transportation efficiency. Simultaneously, the spring 34 ensures that the scraper 32 abuts against the surface of the auxiliary unloading belt 1 as much as possible during the retraction process, facilitating the scraper 32's removal of mineral powder from the auxiliary unloading belt 1.

[0039] Reference Figure 1 and Figure 3 The unfolding assembly 4 includes a third fixed plate 41, a second storage roller 42, a connecting rope 43, a second extension rod 44, a second rotating handle 45, and a second limiting screw 46. Two third fixed plates 41 are provided, and the two third fixed plates 41 are fixedly connected to the side of the truck compartment 100 facing away from the unloading port of the truck compartment 100. The second storage roller 42 is rotatably connected between the two third fixed plates 41. One end of the connecting rope 43 is fixed to the second storage roller 42 and wrapped around it. The other end of the connecting rope 43 passes through the side wall of the truck compartment 100 and is fixedly connected to the side wall of the second slider 11. The second extension rod 44 is fixedly connected to the end of the second storage roller 42. The second rotating handle 45 is fixedly connected to the end surface of the second extension rod 44 facing away from the second storage roller 42. The second limiting screw 46 is located at the end of the second rotating handle 45 facing away from the second extension rod 44. The second limiting screw 46 passes through the second rotating handle 45 and is threadedly connected to the side wall of the truck compartment 100. After the mineral powder material remaining on the surface of the auxiliary unloading belt 1 is cleaned, the second rotating handle 45 is rotated. The second rotating handle 45 can drive the second extension rod 44 to rotate, so that the second storage roller 42 rotates, so that the connecting rope 43 is stored on the second storage roller 42, and then the auxiliary unloading belt 1 is laid on the bottom surface of the truck compartment 100, which is convenient for the reuse of the auxiliary unloading belt 1.

[0040] The implementation principle of the auxiliary unloading device for mining trucks in the embodiment of the present application is as follows: After the truck unloads, the first limiting screw 25 and the second limiting screw 46 are removed. After the first limiting screw 25 and the second limiting screw 46 are removed, the first receiving roller 22 is rotated to allow the auxiliary unloading belt 1 to be withdrawn from the truck compartment 100. During the withdrawal process of the auxiliary unloading belt 1, the scraper 32 can scrape off the mineral powder material on the auxiliary unloading belt 1, thereby reducing the mineral powder material remaining in the truck compartment 100 and improving the truck's transportation efficiency. After the mineral powder material remaining on the surface of the auxiliary unloading belt 1 is cleaned, the second receiving roller 42 is rotated to allow the connecting rope 43 to be stored in the second receiving roller 42, so that the auxiliary unloading belt 1 is laid on the bottom of the truck compartment 100, facilitating the reuse of the auxiliary unloading belt 1.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
