[0036] The guide assembly includes a guide slider 10 symmetrically fixedly connected to one end of the ejector rod 5, and a guide slot 11 adapted to the guide slider 10 is provided on the inner side of the discharge port 4;

[0037] Moreover, one end of the truncated cone block 6 is fixedly connected with a sealing rubber sleeve 12;

[0038] Moreover, one end of the adding bucket 3 is symmetrically fixedly connected to a positioning bracket 13, one end of the positioning bracket 13 is symmetrically provided with a positioning hole 14, a weight sensor 15 is arranged on the top of the mounting platform 2, and a positioning rod 26 adapted to the positioning hole 14 is symmetrically fixedly connected to the top of the mounting platform 2, and a controller 16 is fixedly connected to one side of the mixing box 1, and the controller 16 is electrically connected to the weight sensor 15 and the driving motor 8.

[0039] When in use, firstly, the adding bucket 3 filled with concrete admixture is installed on the top of the mounting platform 2, and the adding bucket 3 drives the positioning bracket 13 to align the positioning hole 14 with the positioning rod 26, and then the positioning hole 14 is sleeved on one end of the controller 16, and at the same time, the adding bucket 3 drives the feeding port 4 to be inserted into the mixing box 1, and under the action of gravity, the adding bucket 3 drives the positioning bracket 13 to squeeze the weight sensor 15, and at the same time, the weight sensor 15 is used to sense the gravity of the adding bucket 3, and the sensing data is transmitted to the controller 16;
