[0037] The inside of the screen box 12 is provided with a scraper 25, which can be in contact with the inner wall of the screen box 12, and the scraper 25 is fixedly installed with a pull rod 26, which can pass through one side of the screen box 12, and the end of the pull rod 26 can be held, so that the pull rod 26 can be pulled, and the scraper 25 can move in the inside of the screen box 12, so that the remaining sand in the inside of the screen box 12 can be concentrated and scraped, and the inside of the screen box 12 can be kept clean.
[0038] Meanwhile, the inner wall of the screen box 12 is fixedly installed with an inclined plate 28, which can be located above the scraper 25, so that when the scraper 25 is at the inner end of the screen box 12, the scraper 25 can be blocked by the inclined plate 28, so that the sand can be prevented from falling on the scraper 25 when being screened, and the sand can also be prevented from falling on one side of the scraper 25.
[0039] And the inner wall of the screen box 12 is fixedly installed with side plates 29 on both sides, which are located above the scraper 25, so that the scraper 25 will be in contact with the bottom of the side plate 29 when moving, so that the side plate 29 can limit the scraper 25, thereby preventing the scraper 25 from moving deviation.
[0040] Finally, the pull rod 26 is fixedly installed with a threaded block 210 near the scraper 25, and the scraper 25 is provided with a threaded hole matched with the threaded block 210, so that the pull rod 26 can be separated from the scraper 25 through the cooperation between the threaded block 210 and the threaded hole, so that the scraper 25 can be disassembled in the inside of the screen box 12, thereby facilitating the later maintenance of the scraper 25.
