In a particular embodiment, the rotary drive 2211 includes a rotary cylinder and a rotary wheel in driving connection. The bearing plate 2212 is connected with the rotating wheel to rotate along with the rotating wheel at different angles. In a specific embodiment, the sand storage tank 100 and the liquid material device 200 are supported and disposed on the fixing base 400, the rotary driving member 2211 is installed on the fixing base 400, that is, the rotary cylinder and the rotating wheel are both installed on the fixing base, so that the bearing plate is reliably and stably disposed on the rotating wheel to rotate at different angles, and then one end of the bearing plate away from the rotating wheel can be movably abutted on the sand mixing tank. Wherein, the bearing plate 2212 has a bearing surface to hold sand, and when it rotates to a certain extent, it will abut against the feed inlet of the sand mixing tank 300, so that the sand of the sand storage tank 100 can enter the bearing plate 2212 through the feed outlet, and then be conveyed to the sand mixing tank 300. In the state shown in fig. 2 where the carrier plate 2212 is at two different positions along the rotating wheel, the sand mixing tank is in the sand mixing state in the dotted line state, and the carrier plate 2212 abuts against the sand mixing tank in the sand charging state in the solid line state.
In one embodiment, the liquid material feeding mechanism 210 includes a liquid material driving member 211 and a liquid material feeding member 212, which are drivingly connected to each other, and the liquid material feeding member 212 is connected to the liquid material spraying mechanism 220.

In this way, the liquid cylinder can control the pushing of the liquid adding member 212 to perform the piston movement, thereby facilitating the rapid pushing of the liquid from the liquid adding member 212 to the liquid spraying mechanism 220. Preferably, an infusion hose 224 is connected to the liquid adding member 212, and the infusion hose 224 is communicated with the liquid spraying mechanism 220. Thus, by providing the infusion hose 224, it is possible to overcome the inconvenience of timely replenishing the liquid material due to the liquid material introducing member 212 being far away from the liquid material spraying mechanism provided on the loading plate 2212.
Referring to fig. 3, in one embodiment, the liquid spraying mechanism 220 includes a shroud 222 and a spraying head 223, the shroud 222 is mounted on the carrying plate 2212, a sand flowing channel is formed through the shroud 222 along a direction parallel to the carrying plate 2212, and the spraying head 223 is mounted on the shroud 222 for spraying the liquid to the sand flowing in the sand flowing channel. Specifically, the shield 222 includes a bearing portion and two supporting portions disposed at two ends of the bearing portion, and the two supporting portions are disposed at two sides of the bearing plate 2212 along a direction parallel to the extending direction of the bearing plate. In this way, a sand flow channel is formed between the two supports and carriers of the shroud 222, allowing sand in the sand storage tank to enter the sand mulling tank as it passes through the carrier plate 2212. Specifically, the injection head 223 is connected with the infusion hose 224 and is fixedly arranged on the bearing part of the shield 222, and injects the liquid material towards the sand flowing channel, so that the sand flowing through the sand flowing channel is injected with the liquid material, and preliminary sand mixing is completed in the process of entering the sand mixing tank along the bearing plate, so that the sand mixing duration of the sand material in the sand mixing tank is reduced, and the sand mixing abrasion between the sand material and the sand mixing tank is reduced.
It should be noted that the installation height of the sand storage tank 100 is higher than that of the sand mixing tank 300, and when the bearing plate 2212 abuts against the feed inlet of the sand mixing tank, the bearing plate is in a downward inclined state, so as to ensure that the sand falling from the sand storage tank 100 is smoothly fed into the sand mixing tank 300 after being loaded.
In one embodiment, a first stirring blade 310 and a second stirring blade 320 which are staggered with each other are disposed in the sand mixing tank 300, one end of each of the first stirring blade 310 and the second stirring blade 320 is fixedly disposed on the inner side wall of the sand mixing tank, and the other end of each of the first stirring blade and the second stirring blade extends toward the center of the sand mixing tank. In one embodiment, the connection portion of the sand mixing tank near the first stirring blade 310 is provided with the feeding hole, and the connection portion of the sand mixing tank near the second stirring blade 320 is provided with the discharging hole. Specifically, the ends of the first stirring blade 310 and the second stirring blade 320 extending towards the center of the sand mixing tank have bent portions, which facilitates the two stirring blades to form a relatively continuous sand material channel when they are arranged in a staggered manner. In addition, in order to facilitate the sand to smoothly enter and exit the sand mixing tank, in one embodiment, the ends of the first stirring blade 310 and the second stirring blade 320 connected to the sand mixing tank are disposed at a complete angle. Thus, the sand material can form a buffer surface, and the sand material can enter or fall conveniently.

It should be noted that, because the first stirring blade 310 and the second stirring blade 320 are arranged in a staggered manner, and the sand mixing tank 300 is designed to be controlled by positive rotation, the sand material cannot be thrown out from the sand material channel, the mixed material cannot exceed half of the height of the sand mixing tank in the control of the sand material amount, or the mixed material cannot be controlled to not be thrown out in positive rotation. On the contrary, if the sand mixing tank 300 is controlled to rotate reversely, the sand will fall out through the discharge port of the sand mixing tank because the stirring motion of the sand in the two stirring vanes will not form continuous mixing along the sand passage along with the reverse rotation. This process can be understood in particular with reference to the concrete mixers used in construction sites of the prior art and will not be described in detail here.
In one embodiment, the sand mixing tank is provided with a driving wheel 330 for driving the sand mixing tank 300 to rotate forward or backward.

Wherein the mounting bracket 600 includes a tripod or a rectangular bracket. In this way, it is advantageous to carry the sand mixing tank 300 by providing the mounting bracket 600 to support so as to realize free running, and at the same time, to provide mounting support for the synchronous pulley mechanism 500.
In order to timely hold the mixed sand, in one embodiment, the sand mixer further includes a sand leaking hopper 700, and shakeout at the discharge port of the sand mixing tank 300 is held by the sand leaking hopper 700.
