[0033] Among them, a main body seat 301 with a rectangular block structure is welded on the front end face of the scraper 1, and two first guide rods 302 are welded on the top end face of the main body seat 301. The two first guide rods 302 are both cylindrical rod-shaped structures, and a mounting block 303 with a rectangular block structure is slidably connected to the two first guide rods 302; a threaded rod 304 is threadedly connected to the main body seat 301, and the upper end of the threaded rod 304 is rotatably connected to the bottom end face of the mounting block 303.
[0034] Among them, the adjustment part of the threaded rod 304 is a hexagonal structure, and an adjustment groove 305 is provided on the bottom end surface of the adjustment part of the threaded rod 304. The adjustment groove 305 is a hexagonal groove structure. When the wrench used for adjusting the threaded rod 304 is damaged or lost, an Allen wrench can also be used to insert into the adjustment groove 305 for adjustment.
[0035] Among them, two second guide rods 306 with stepped shaft-like structures are slidably connected to the mounting block 303, and the upper ends of the two second guide rods 306 are welded to the bottom end surface of the protective plate 307; two spring rods 308 are welded to the top end surface of the mounting block 303, and the upper ends of the two spring rods 308 are welded to the bottom end surface of the protective plate 307, and the top surface of the protective plate 307 is higher than the top surface of the scraper 1. During use, the protective plate 307 can replace the scraper 1 for conveying operations, and during the conveying process, when the protective plate 307 collides with a hard object, the protection of the protective plate 307 can be achieved through the contraction of the two spring rods 308.
[0036] Among them, two cylindrical tubular protective covers 309 are welded on the bottom end surface of the protective plate 307, and the two protective covers 309 are respectively sleeved on the two spring rods 308. At this time, the protruding ends of the two spring rods 308 are in a sealed state. During use, the protective covers 309 protect the protruding parts of the spring rods 308, which can prevent the spring rods 308 from bumping during transportation and reduce the probability of maintenance. Embodiment 2:
[0037] On the basis of Example 1, two sliding grooves 101 are symmetrically opened on the front end surface of the scraper 1, and the two sliding grooves 101 are both T-shaped groove structures; two sliding protrusions 310 are symmetrically welded on the rear end surface of the protective plate 307, and the two sliding protrusions 310 are both T-shaped structures.

During use, the sliding connection between the sliding protrusions 310 and the sliding grooves 101 can improve the stability of the connection between the protective plate 307 and the scraper 1, thereby avoiding excessive force on the main seat 301 during transportation, which may cause welding to open.
[0038] Working principle: When in use, the two fixing seats 2 are fixed to the chain of the scraper by four fixing screws 201. When the chain rotates, the protective plate 307 contacts the storage slot at the bottom of the scraper. When the chain drives the scraper 1 to move, the material can be transported through the protective plate 307. When the protective plate 307 collides with a hard object, the protection of the protective plate 307 can be achieved by contracting the two spring rods 308. When the position of the protective plate 307 needs to be adjusted, the threaded rod 304 can be rotated. When the threaded rod 304 is rotated, the mounting block 303 can be driven by the threaded rod 304 to move upward, and the mounting block 303 can drive the protective plate 307 to move upward.
