[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a stirring mechanism and a scraper. The first motor drives the stirring shaft to rotate, and the rotating scraper can scrape off the sand adhering to the inner wall of the groove, ensuring that the sand does not adhere to the inner wall of the groove. In addition, a movable disassembly mechanism is provided, which can simultaneously pull the two insert rods outward. The insert rods drive the locking block to move, and the locking block leaves the inner side of the locking slot. The locking block retracts into the inner side of the receiving slot, releasing the limitation on the insert block. Under the action of the second spring, the insert block is pushed upward, which can remove the horizontal plate and the stirring mechanism from the inner side of the sand mixing box, thereby facilitating the cleaning of the stirring mechanism. This utility model can scrape off the sand adhering to the inner wall of the groove, making it convenient to disassemble and assemble the stirring mechanism, thus facilitating the cleaning of the stirring mechanism.

[0014] 2. This utility model incorporates a striking mechanism. During the material feeding process, controlling the switch of the second motor causes the rotating shaft to rotate, which in turn causes the cam to rotate around the shaft, pushing the striking column. The striking column then swings back and forth, striking the feeding pipe at intervals. This causes the entire feeding pipe to vibrate at high frequency and low amplitude, ensuring smoother feeding of the finished sand and preventing blockage of the feeding pipe. This utility model, by incorporating the striking mechanism, can prevent blockage of the feeding pipe and ensure smooth material feeding. Attached Figure Description

A cam 804 is sleeved on the outer surface of the rotating shaft 805.

[0023] The first motor 401 is fixedly installed on the upper end face of the horizontal plate 3. The lower end face of the first motor 401 is fixedly connected to the upper end face of the stirring shaft 404 through a coupling. The outer surface of the scraper 403 is in contact with the arc surface and the inner wall of the groove 5. When the first motor 401 works, it can drive the stirring shaft 404 to rotate. The rotation of the scraper 403 can scrape off the sand attached to the inner wall of the groove 5.

[0024] The lower end face of the stirring shaft 404 is rotatably connected to the upper end face of the strip plate 405 through a bearing. The bottom surface of the groove 5 is connected to the feed pipe 11 through a guide groove. A solenoid valve is installed on the inner side of the feed pipe 11 to improve the stability of the rotation of the stirring shaft 404. When the stirring shaft 404 moves upward, it can drive the strip plate 405 to move upward.

[0025] The movable disassembly mechanism 2 includes a plug rod 202, which is installed on both sides of the outer surface of the sand mixing box 1 through a through hole 203. A first spring 201 is sleeved on the outer surface of the plug rod 202, and a storage groove 204 is provided on the inner side wall of the through hole 203.

[0026] A locking block 205 is installed on the opposite side of the outer surface of the two inserts 202, and a slot 207 is provided on the opposite side of the outer surface of the two inserts 9. The locking block 205 can be inserted into the inside of the slot 207.

Under the action of the second spring 208, the insert block 9 is pushed upwards, allowing the horizontal plate 3 and the stirring mechanism 4 to be removed from the inside of the sand mixing box 1, thus facilitating the stirring... The mixing mechanism 4 is cleaned by a striking mechanism 8. During the feeding process, the second motor 806 can be switched on and off. The second motor 806 drives the rotating shaft 805 to rotate, which in turn drives the cam 804 to rotate around the rotating shaft 805, pushing the striking column 801. The striking column 801 swings back and forth, striking the feeding pipe 11 at intervals, thereby causing the entire feeding pipe 11 to generate high-frequency, low-amplitude vibrations, making the finished sand feed more smoothly and preventing the feeding pipe 11 from getting blocked. This utility model can scrape off the sand attached to the inner wall of the groove 5, making it easier to disassemble and assemble the mixing mechanism 4, thus facilitating the cleaning of the mixing mechanism 4. Moreover, by setting the striking mechanism 8, the feeding pipe 11 can be prevented from getting blocked, ensuring smooth feeding.
