The top of the support frame 1 is fixedly connected to the outer shell 2, and the inner wall of the outer shell 2 is fixedly connected to the partition 3; the protective component includes a first fixed block 4, a first connecting rod 5, a second connecting rod 6, a third connecting rod 7, a second fixed block 8, a first protective cover 9, a hand lever 10, a rotating shaft 11 and a second protective cover 12, one end of the partition 3 is fixedly connected to the first fixed block 4, one end of the first fixed block 4 is rotatably connected to the first connecting rod 5, the outer wall of the first connecting rod 5 is rotatably connected to the second connecting rod 6, the outer wall of the second connecting rod 6 is rotatably connected to the third connecting rod 7, the end of the third connecting rod 7 away from the first connecting rod 5 is provided with a second fixed block 8, one end of the second fixed block 8 is fixedly connected to the first protective cover 9, the inner wall of the first protective cover 9 is penetrated by a hand lever 10, the inner wall of the outer shell 2 is penetrated by a rotating shaft 11, and the outer wall of the outer shell 2 is provided with a second protective cover 12.

[0022] Among them, Figure 3 As shown, the first protective cover 9 forms a rotating structure with the outer shell 2 through the rotating shaft 11, which is beneficial for shielding the internal dust through the protective cover when the scraper is operating, preventing the operator from excessively inhaling dust and causing damage to the body. The design of the protective cover has a certain protective effect on blocking dust.

[0023] Among them, Figure 3 As shown, the surfaces of the first protective cover 9 and the second protective cover 12 fit closely together, which is beneficial for effectively preventing dust from overflowing when the first protective cover 9 and the second protective cover 12 are closed and shielded.

[0024] Among them, Figure 2 As shown, two groups of hand levers 10 are provided, and the position relationship of the two groups of hand levers 10 is symmetrical about the midpoint of the partition 3, which is conducive to opening and closing the first protective cover 9 and the second protective cover 12 through the two groups of hand levers 10. Opening is convenient for checking whether the internal parts can operate normally. Under normal circumstances, the protective cover can be closed for protective operation when transporting materials. Example 2

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, the inner wall of the outer shell 2 is rotatably connected to the fourth connecting rod 13, the inner wall of the outer shell 2 is rotatably connected to the fifth connecting rod 14, the inner wall of the fifth connecting rod 14 is fixedly connected to the support rod 15, one end of the fifth connecting rod 14 is provided with a door panel 16, the outer wall of the door panel 16 is provided with a door handle 17, the top end of the outer shell 2 is provided with a feed port 18, and the bottom end of the outer shell 2 is provided with a discharge port 19.

[0026] Among them, Figure 4 As shown, the door panel 16 forms a door opening structure with the outer shell 2 through the fourth connecting rod 13 and the fifth connecting rod 14, which is conducive to moving the door panel 16 by pulling the door handle 17. At this time, the fourth connecting rod 13 and the fifth connecting rod 14 play a connecting role between the door panel 16 and the outer shell 2, thereby realizing the opening operation of the door panel 16, and facilitating the maintenance operation of the internal parts of the scraper by the operating personnel.

[0027] Among them, Figure 1 As shown, two groups of the fourth link 13 and the fifth link 14 are provided, and the positional relationship of the two groups of the fourth link 13 and the fifth link 14 is symmetrical about the center of the door panel 16, which is beneficial for the two groups of the fourth link 13 and the fifth link 14 to more stably drive the door panel 16 to open and close.

[0028] During use: first, the user rotates the two sets of hand levers 10 to drive the first protective cover 9 and the second protective cover 12 to open and close through the rotating shaft 11. The rotation of the first protective cover 9 and the second protective cover 12 drives the second connecting rod 6 and the third connecting rod 7 to rotate, thereby driving the first connecting rod 5 to rotate. The movement of the connecting rod makes the first protective cover 9 and the second protective cover 12 have a more stable opening and closing operation. Opening the first protective cover 9 and the second protective cover 12 is convenient for checking whether the internal parts can operate normally. Under normal circumstances, the protective cover can be closed for protective operations when transporting materials to prevent operators from excessive inhalation of dust and causing damage to the body. The design of the protective cover has a certain protective effect on blocking dust.

[0029] Finally, the door panel 16 is driven to move by pulling the door handle 17. At this time, the fourth connecting rod 13 and the fifth connecting rod 14 connect the door panel 16 with the outer shell 2. There are two groups of the fourth connecting rod 13 and the fifth connecting rod 14. The two groups of the fifth connecting rod 14 are connected by the support rod 15, which can more stably realize the opening operation of the door panel 16, and is convenient for the operator to perform maintenance operations on the internal parts of the scraper. After maintenance, the door panel 16 is closed to realize the protection operation of the side outer shell 2 of the scraper.
