A solenoid valve 7 is fixedly connected to the lower end of the weighing bin 1. The solenoid valve 7 is used to discharge the concrete and the cleaning water.

[0025] During operation, after each weighing, at this time the solenoid valve 7 is in an open state, then the water pipe 402 is connected to an external water pipe, and external clean water begins to be poured into the inside of the water tank 401, and then sprayed out through each cleaning nozzle 403, starting from the uppermost end inside the weighing bin 1 to clean the remaining sticky concrete on the inner wall of the weighing bin 1, and then discharged through the lower end of the weighing bin 1.

[0026] Embodiment 2:

[0027] On the basis of Embodiment 1, a limiting mechanism 8 is provided on both sides of the weighing chamber 1.

The upper end of the fixed column 801 is fixedly connected to the lower surface of the weighing chamber fixing seat 2. A sliding groove 802 is formed on one side of the fixed column 801. A sliding block 803 is slidably arranged inside the sliding groove 802. The sliding block 803 drives the weighing chamber 1 to slide, and at the same time limits the weighing chamber 1 to prevent the weighing chamber 1 from detaching, improving the weighing effect. The other end of the sliding block 803 is fixedly connected to one side of the weighing chamber 1. The weighing mechanism 3 includes a weighing device 301, a fixed block 302 and a pressing plate 303.

The pressing plate 303 is fixedly connected to the lower surface of the fixed block 302. After the weighing chamber 1 bears the concrete, the fixed block 302 descends to press the weighing device 301, and then the weighing device 301 weighs. The stirring mechanism 5 includes a stirring tank 501, a transmission pipe 502 and a stirring tank fixing seat 503. The stirring tank fixing seat 503 is fixedly connected to the middle of the stirring tank 501. The transmission pipe 502 is fixedly connected to the lower end of the stirring tank 501. The lower end of the transmission pipe 502 is arranged directly above the weighing chamber 1.

A plurality of support legs 506 are fixedly connected to the lower surfaces of the weighing chamber fixing seat 2 and the stirring tank fixing seat 503;

[0028] After the stirring tank 501 stirs the concrete, it is transmitted to the inside of the weighing chamber 1 through the transmission pipe 502. Subsequently, the weighing chamber 1 is weighed and then descends, and the gravity is transmitted to the weighing device 301 through the fixed block 302. The weighing device 301 evenly distributes the gravity on both sides of the weighing chamber 1 and then detects the weight of the concrete. After the weighing is completed, the solenoid valve 7 is opened to transmit the concrete out.

[0029] The above is only the preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the application shall be included in the protection scope of the present application.
