[0025] In order to solve the technical problems in the prior art that the stirring mechanism is a single set of stirring blades, the stirring efficiency is low, and the sand is easy to adhere to the inner wall of the equipment, which makes it inconvenient to clean the equipment, please refer to Figure 1-4 , providing the following technical solutions:

[0026] In the present embodiment, a mixing and stirring structure for a sand screening and drying device for mortar production includes a main transmission shaft 1 and a fixed rod 602. A turntable 2 is fixedly arranged on the outer wall of the main transmission shaft 1, and a contact plate 3 is arranged below the turntable 2.

A water inlet pipe 5 is arranged at the front end of the main transmission shaft 1, and a scraper plate 6 is arranged at the rear end of the main transmission shaft 1. The main transmission shaft 1 is driven by a motor so that the main transmission shaft 1 drives the turntable 2 and the contact plate 3 to rotate together when it rotates. The rotation of the turntable 2 drives the water inlet pipe 5 and the scraper plate 6 to rotate together. The scraper plate 6 fits the inner wall of the equipment to scrape off the material adhered to the inner wall. In conjunction with the water inlet pipe 5 spraying water, the inner wall of the equipment can be cleaned in time to avoid the difficulty in cleaning caused by the material adhering to the inner wall of the equipment for a long time.

[0027] A driving wheel 102 is provided above the turntable 2, and the driving wheel 102 is fixedly connected to the main transmission shaft 1, and synchronous wheels 103 are respectively meshed on both sides of the driving wheel 102, and a slave transmission shaft 101 is fixedly provided inside the synchronous wheel 103, and the slave transmission shaft 101 is rotatably connected to the turntable 2 through a bearing. The rotation of the driving wheel 102 can drive the driving wheel 102 to rotate together, and the driving wheel 102 is meshed with the synchronous wheels 103 on both sides, thereby driving the slave transmission shaft 101 to rotate.

The rotating shaft 402 is fixedly connected to the slave transmission shaft 101 through the coupling 401, and the stirring blade 403 is fixedly arranged on the outer wall of the rotating shaft 402. Since the rotating shaft 402 of the stirring mechanism 4 is fixed to the slave transmission shaft 101 through the coupling 401, the rotation of the slave transmission shaft 101 drives the stirring mechanism 4 to rotate together, so that the stirring blade 403 fully stirs the material. The number of stirring mechanisms 4 can be set according to actual needs. The simultaneous rotation of multiple groups of stirring mechanisms 4 improves the stirring efficiency and improves the material drying efficiency.
