A first electric push rod 15 is fixedly installed on the frame 14, and a first connecting rod 16 is fixedly connected to the bottom end of the telescopic rod of the first electric push rod 15, and a blocking plate 17 is fixedly connected to the bottom end of the first connecting rod 16. Two weighing boxes 18 are fixedly connected to the mixing box 2, and a fourth fixed frame 19 is fixedly connected to the weighing box 18. A second electric push rod 20 is fixedly installed on the fourth fixed frame 19, and a second connecting rod 21 is connected to the telescopic rod of the second electric push rod 20, and a propulsion plate 22 is fixedly connected to the second connecting rod 21. The propulsion plate 22 is used to push the raw materials, a weight sensor 23 is installed on the weighing box 18, the weight sensor 23 is used to detect the weight of the raw materials, two indicator lights 24 are installed on the mixing box 2, a plurality of wheels 25 are installed on the chassis 1, a plurality of hydraulic cylinders 26 are fixedly installed on the chassis 1, the bottom end of the telescopic rod of the hydraulic cylinder 26 is fixedly connected to a third connecting rod 27, the bottom end of the third connecting rod 27 is fixedly connected to a counterweight block 28, the counterweight block 28 is used to improve the stability of the chassis 1, and a distance sensor 30 is installed on the third fixed frame 14.

[0021] The controller 3 is provided with a timer.

[0022] A handle frame 29 is fixedly connected to the chassis 1 .

[0023] The counterweight 28 is provided with a buffer pad.

[0024] The working principle of the utility model is as follows: the distance sensor is provided with a first threshold value and a second threshold value, and the value of the first threshold value is smaller than the value of the second threshold value.

[0025] The first step is to inject the raw materials to be mixed into the weighing box. The weight sensor detects the weight of the raw materials. When the weight of the raw materials in the weighing box reaches the preset threshold of the weight sensor, the control indicator light will light up for a period of time and then go out. At this time, stop injecting raw materials. The weight sensor can accurately detect the weight of the raw materials, thereby ensuring that the proportion of the raw materials when mixed is accurate, thereby eliminating the step of staff using a weighing machine to weigh the raw materials before mixing.

[0026] In the second step, after the indicator light goes out, the first electric push rod will be controlled to drive the first connecting rod and the blocking plate to rise, so that the blocking plate opens the discharge channel of the weighing box. When the distance between the blocking plate and the distance sensor reaches the first threshold preset by the distance sensor, the first electric push rod will be controlled to stop working, and the first drive motor and the second drive motor will be controlled to work at the same time. The second electric push rod will be controlled to stop after working for a certain period of time. The first drive motor drives the first rotating shaft and the first agitator to rotate, and the second drive motor drives the second rotating shaft and the second agitator to rotate. The second electric push rod drives the second connecting rod and the propulsion plate to move, and the propulsion plate pushes the raw materials, so that the raw materials slide into the mixing box through the discharge channel, and the first agitator and the second agitator stir and mix the raw materials. When the first agitator and the second agitator work at the same time, the mixing efficiency of the raw materials is improved, and the mixing time of the raw materials is further shortened.

[0027] The third step is that when the time for mixing the raw materials reaches the time preset by the timer, the first drive motor and the second drive motor are controlled to stop working, and the second electric push rod is controlled to drive the second connecting rod and the pushing plate to move in the opposite direction to reset, and then the first electric push rod is controlled to drive the first connecting rod and the blocking plate to descend. When the distance between the blocking plate and the distance sensor reaches the second threshold preset by the distance sensor, the first electric push rod is controlled to stop working, so that the blocking plate blocks the discharge channel of the weighing box, and then the push handle frame is pushed, so that the wheels drive the chassis and the mixing box to move, and the mixing box stops pushing after moving to the specified position. Move the push hand frame, and then place the storage box under the discharge pipe, control the hydraulic cylinder to drive the third connecting rod and the counterweight block to descend, and after the counterweight block descends to contact the ground, the chassis, mixing box and wheels rise, thereby improving the stability of the mixing box and preventing the mixing box from shifting during discharging and causing the raw materials to spill on the ground. Control the valve to open the discharge pipe channel so that the raw materials fall into the storage box through the discharge pipe channel, thereby completing the collection work. After the raw materials are collected, control the valve to close the discharge pipe channel, and then control the hydraulic cylinder to drive the third connecting rod and the counterweight block to rise and reset, so that the wheels can contact the ground.
