In the present embodiment, the number of feeding equipment 1 is two, which is filled with solidifying agent and soil respectively, the number of water adding equipment 2 is one, which is fixedly arranged at the upper part of the protective barrel, and the mixing equipment 4 is arranged at the bottom of the protective barrel.

[0034] It also includes a control system 3. It should be noted that the control system 3 in the present example adopts existing technology, which can control the feeding equipment 1 and the water adding equipment 2 to work in turn according to the amount of feeding and water adding input in advance, i.e. the ratio, so as to control the mixing equipment 4 to work after the feeding and water adding work is completed, thereby realizing the automatic preparation of flow state solidified soil. In the present embodiment, no improvement is made to the control system 3 itself, and such control system is relatively common, such as that used in commercial concrete production line.

[0035] As shown in the figure, Figures 3-5 The feeding equipment 1 includes a hollow barrel 101, which is composed of a large cylindrical segment, a frustum segment and a small cylindrical segment, which are fixedly connected in sequence; a weighing device is arranged between the large cylindrical segment and the protective barrel. The weighing device includes a weighing support 104 fixedly sleeved on the large cylindrical segment and a pressure sensor 102 fixedly arranged on the protective barrel.

[0036] The weighing support 104 comprises an annular support to which a linear support is fixedly connected. It can be understood that the diameter of the large cylindrical segment is consistent with the inner diameter of the annular support. The linear support of the weighing support 104 is connected to the support shaft 103 through a rotating shaft. Figure 1 、 Figure 2 、 Figure 3 As shown in the figure, the two ends of the support shaft 103 are fixedly connected to the inner wall of the protective cylinder. A plurality of pressure sensors 102 are fixedly arranged on the inner wall of the protective cylinder. The pressure sensors 102 are connected to the control system 3. The other end of the linear support is close to the lower side of the pressure sensor 102.

[0037] Through the principle of the lever, the weight of the feeding device and the internal material can be measured by the pressure sensor 102 fixedly arranged on the inner wall of the protective cylinder. The change in pressure can be converted into the feeding amount. When feeding, the material in the cylinder 101 is reduced, and the pressure sensed by the pressure sensor 102 is reduced. The feeding amount is converted by the reduced pressure. The conversion ratio of pressure and weight is set according to the actual situation. The pressure sensor can transmit the pressure change of the feeding device to the control system in real time. The control system converts the pressure change into the actual material feeding weight. The feeding port is located above the mixing device.

The powder solidifying agent and the soil enter the mixing device 4. When the feeding amount reaches the preset value, the control system 3 controls the electromagnet 106 to be powered on and attracts the strong magnet 108 to close the cover plate 107, so as to realize accurate control of the feeding amount.

It can be understood that the second stirring shaft 406 is internally hollow, and the inner wall of the second stirring shaft 406 is larger than the outer wall of the first stirring shaft 404, and the inner walls at both ends of the second stirring shaft are rotatably connected with the first stirring shaft 404 through bearings.

[0044] As Figure 7 shown, one end of the second stirring shaft 406 located outside the stirring bin is fixedly connected with a third bevel gear 405, and the other end located inside the stirring bin is fixedly connected with a second stirring shaft blade group 408. The second stirring shaft blade group 408 includes a cylindrical framework, and a plurality of second stirring shaft blades are fixedly arranged on the cylindrical framework. The second stirring shaft blades are uniformly arranged along the circumferential direction of the cylindrical framework, and the plurality of second stirring shaft blade groups are uniformly arranged along the axial direction of the cylindrical framework.
