Detailed Description

In order to make the above objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the invention.

As shown in fig. 1-3, the utility model discloses a feeding mechanism of concrete mixing tank, it includes: the feeder 101 is provided with an open cavity 102, and the bottom of the open cavity 102 is provided with at least two discharge ports 104; a fan blade 103, the radius of the fan blade 103 is equal to or smaller than the radius of the open cavity 102, and the fan blade 103 is rotatably installed in the open cavity 102; a sieving piece 105, wherein a sieving groove 106 or a sieving hole is arranged on the sieving piece 105, and the sieving piece 105 is installed on the discharge hole 104; the conveying pipeline 111 is internally provided with a through hole, and the conveying pipeline 111 is installed at the bottom of the discharge hole 104; a bracket 112, wherein the bracket 112 is arranged at the bottom of the feeder 101. It should be noted that: the shape and size of the sieving piece 105 are the same as those of the discharge ports 104, the sieving piece 105 is installed at the top of the discharge ports 104 in a clamping manner, and generally only one sieving piece 105 is arranged at one discharge port 104.

It should be noted that: the raw materials are conveyed to the side, where the discharge hole 104 is not formed, of the open cavity 102 through the conveying pipeline 111, the fan blades 103 rotate to stir the raw materials and simultaneously stir the blocky raw materials, when the fan blades 103 pass through the discharge hole 104 provided with the sieving piece 105, the raw materials can be sieved, finely crushed powdery raw materials can pass through the sieving piece 105 and enter a stirring barrel, meanwhile, the sieving piece 105 and the fan blades 103 can also be matched with one another to crush part of granular raw materials, and the raw materials which do not pass through the sieving piece 105 are brought to the other discharge hole 104 for recycling. It should be noted that, in order to facilitate the feeding of the open cavity 102, a notch 120 may be provided on the side wall of the open cavity 102, and one end of the transfer pipe 111 is butted to convey the raw material; similarly, for facilitating discharging, the discharging pipe 109 can be installed on the discharging port 104, so that the sieved raw materials can be conveniently guided to the stirring barrel.
