A binder and additives are added, and the casting method is selected for construction during construction. Before use, the trough castable needs to be fully mixed with other binders and additives by a mixing device.

[0003] When the existing mixing device for the production of bulk trough castables is in use, the feeding port does not have the function of screening raw materials, resulting in some agglomerated raw materials being put into the inside of the mixing barrel together. And during feeding, the position of the feeding pipe opening is fixed, and the raw materials always fall at a fixed position, resulting in a low feeding uniformity.

[0004] Therefore, aiming at the problems that the existing mixing device for the production of bulk trough castables does not have the function of screening raw materials and has a low feeding uniformity during use, a mixing device for the production of bulk trough castables can be designed. When feeding, the vibration motor is started, and the vibration motor drives the filter screen to vibrate, so that the raw materials can be screened. At the same time, the driving motor is started to drive the driving gear to rotate, and the driving gear drives the driven gear meshed with it to rotate synchronously, so as to drive the guide pipe to rotate, so that the raw materials can be evenly scattered into the inside of the mixing barrel during feeding. Content of the Utility Model

[0006] The technical solution of the present utility model is as follows: A mixing device for the production of gunning bulk materials for a trough, comprising a mixing barrel; further comprising a filtering box, a support column, a filter screen, a vibration motor, a rotary connecting seat, a driven gear, a driving motor, a driving gear and a material guiding pipe; three legs distributed circumferentially are installed at a position close to the lower part of the outer surface of the mixing barrel, a discharge port is arranged on the bottom surface of the mixing barrel, a top cover is installed on the top surface of the mixing barrel, a feeding port is installed at the middle position of the upper surface of the top cover, a filtering box is arranged on the upper surface of the feeding port, one ends of support columns are installed at the corners of the bottom surface of the filtering box, and the other ends of the support columns are connected to the upper surface of the top cover. A filter screen is arranged inside the filtering box, a vibration motor is installed on the left side surface of the filtering box, a rotary connecting seat is sleeved on the outer surface of one end of the feeding port inserted into the top cover, a material guiding pipe is rotatably connected to the bottom surface of the rotary connecting seat, a driven gear is installed at a position close to the upper part of the outer surface of the material guiding pipe, a driving motor is installed at a position close to the right side of the upper surface of the top cover, the output end of the driving motor is connected with a driving gear, and the driving gear is meshed with the driven gear.

At the same time, the driving motor is started, and its output end will drive the driving gear to rotate. The driving gear drives the driven gear meshed with it to rotate synchronously, thereby driving the material guiding pipe to rotate, so that the raw materials can be evenly scattered inside the mixing barrel during feeding, improving the mixing efficiency.

By setting the scraping plate, when the stirring rod rotates, the scraping plate will move along the inner wall of the mixing barrel, thus preventing the raw materials from sticking to the inner wall of the mixing barrel.

[0012] Preferably, evenly spaced feeding rods are installed on the side surface of the stirring rod away from the inner wall of the mixing barrel. By setting the feeding rods, when the stirring rod rotates, the feeding rods will be driven to rotate synchronously. The setting of multiple stirring rods can improve the mixing rate of the device.

A control panel is installed on the outer surface of the mixing barrel below the observation port. By setting the observation port and the illuminating lamps, when feeding materials, the staff can see the height of the raw materials inside the mixing barrel through the observation port, thus preventing the raw materials from covering the bottom of the feeding pipe.

[0014] Preferably, a dust cover is installed on the bottom surface of the rotating ring, and the central opening of the dust cover is rotatably connected to the outer surface of the feeding pipe. By setting the dust cover, the dust generated during stirring can be blocked, preventing the dust from adhering to the surfaces of components such as the driving gear and the driven gear, thereby improving the service life of the equipment.

[0015] Advantages of the present utility model:

[0016] 1. By starting the driving motor, its output end will drive the driving gear to rotate. The driving gear drives the driven gear meshed with it to rotate synchronously, thereby driving the feeding pipe to rotate, enabling the raw materials to be evenly scattered inside the mixing barrel during feeding, improving the stirring efficiency, and solving the problem that in the existing mixing device for the production of bulk materials for the iron runner casting, the position of the feeding pipe opening is fixed, and the raw materials cannot be evenly fed, affecting the stirring efficiency.
