[0033] refer to Figure 2 The continuous preparation device of the soil solidifier also includes a driving mechanism for driving the rotating column 5 to rotate, and the driving mechanism includes a full gear ring 51 and a full gear 52. The lower part of the rotating column 5 is fixedly connected to the full gear ring 51 located outside the preparation cylinder 3, and the lower outer wall of the preparation cylinder 3 is installed with a full gear 52 driven by a driving motor, and the full gear 52 is meshed with the full gear ring 51.

[0034] Initially, the material barrel 8 on the right side is filled with raw materials required for preparing the soil solidifying agent, the channel 1 101 on the connecting ball 10 is connected with the pipe 2 92, and the channel 2 102 on the connecting ball 10 is connected with the pipe 3 93. The raw materials in the material barrel 8 on the right side pass through the pipe 2 92, the channel 1 101, the channel 2 102, the pipe 3 93 and the feeding pipe 31 in turn into the preparation barrel 3; the servo motor is controlled to drive the spiral stirrer 4 to rotate forward, and the rotating spiral stirrer 4 stirs the raw materials in the preparation barrel 3 for mixing and preparation. At the same time, with the cooperation of the full gear 52 and the full gear ring 51, the driving motor is controlled to make the rotating column 5 and the stirring rod 6 rotate in the opposite direction together, and the raw materials near the inner wall of the preparation barrel 3 flow in the opposite direction through the long strip 61 of the stirring rod 6, so that the raw materials form convection, and the raw materials are fully mixed through the inclined surface 62 of the stirring rod 6, so that the preparation effect is better, and the solenoid valve can be controlled to make the soil solidifying agent prepared in the preparation barrel 3 be discharged through the discharge pipe 32.

[0035] While the raw materials in the preparation barrel 3 are being prepared, the next batch of various raw materials are added to the left barrel 8 in sequence. When the raw materials in the preparation barrel 3 are prepared, the raw materials in the left barrel 8 are added in sequence. At this time, the connecting ball 10 rotates 120 degrees clockwise to change the connection state. Channel one 101 is connected to pipe three 93, and channel two 102 is connected to pipe one 91, while the bottom end of pipe two 92 is blocked. The raw materials in the left barrel 8 pass through pipe one 91, channel two 102, channel one 101, pipe three 93 and feeding pipe 31 in sequence and enter the preparation barrel 3. Similarly, the raw materials in the preparation barrel 3 are mixed and prepared through the cooperation of the spiral agitator 4 and the stirring rod 6, and the next batch of raw materials can be added to the right barrel 8 at the same time. After the prepared soil solidifier is discharged, the connecting ball 10 rotates 120 degrees counterclockwise to reset, and the raw materials in the right barrel 8 enter the preparation barrel 3. In this way, the raw material adding process and the preparation process can be carried out simultaneously, so that the preparation of the soil solidifier is carried out continuously, thereby improving the overall preparation efficiency.

[0036] Example 2: Based on Example 1, refer to Figure 5 , Fig. 9 and Fig.10 The continuous preparation device of the soil solidifier also includes a pushing mechanism, which includes an electric push rod 111, a lifting rod 112, a fixing rod 113 and a cover plate 114. The front and rear of the upper bracket 7 are bolted with an electric push rod 111, and the telescopic rods of the two electric push rods 111 are connected with lifting rods 112. The ends of the lifting rods 112 away from the electric push rod 111 are welded with fixing rods 113, and the bottom ends of the fixing rods 113 are fixedly connected with cover plates 114. The two cover plates 114 are respectively matched with the inner walls of the two material barrels 8. Rubber rings are provided on the edges of the cover plates 114, and one-way valves are installed on the cover plates 114. The one-way valves and rubber rings are not shown in the figure. The structure and principle of the one-way valves and rubber rings are prior art.

[0037] In the process of the raw materials of the right material barrel 8 entering the preparation cylinder 3, the electric push rod 111 on the rear side is controlled to drive the lifting rod 112 on the rear side to descend, driving the fixed rod 113 on the right side and the cover plate 114 on the right side to descend together, and the cover plate 114 on the right side enters the right material barrel 8, and the rubber ring contacts the inner wall of the right material barrel 8. The raw materials in the right material barrel 8 will not flow out through the one-way valve, and the descending right cover plate 114 can accelerate the outflow speed of the raw materials in the right material barrel 8. When all the raw materials in the right material barrel 8 enter the preparation cylinder 3, the electric push rod 111 on the rear side is controlled to make the rear lifting rod 112, the right fixed rod 113 and the right cover plate 114 rise and reset, and the external air enters the right material barrel 8 through the one-way valve, so that the right cover plate 114 can smoothly rise to the initial position, and the right cover plate 114 is separated from the right material barrel 8; similarly, in the process of the raw materials of the left material barrel 8 entering the preparation cylinder 3, the outflow speed of the raw materials is accelerated by descending the cover plate 114 on the left side, thereby reducing the feeding time.

[0038] Embodiment 3: Based on Embodiment 2, refer to Figure 5 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 The continuous preparation device of the soil solidifying agent also includes a control mechanism for controlling the rotation of the connecting ball 10, the control mechanism includes a connecting plate 121, a sliding rod 122, a contact rod 123, a contact plate 124, a ratchet bar 125, a ratchet bar 2 126, a ratchet gear 127 and a ratchet gear 2 128. A connecting plate 121 is welded to the middle of the upper bracket 7, and two sliding rods 122 that slide up and down are provided on the connecting plate 121. Damping can be set at the sliding connection between the sliding rod 122 and the connecting plate 121 to prevent the lifting rod 112 from sliding randomly under the gravity factor. The top of the sliding rod 122 is fixedly connected to the contact rod 123, and the fixed The middle part of the rod 113 is fixedly connected with a contact plate 124 whose top contacts the contact rod 123. The downward movement of the contact plate 124 will push the contact rod 123 to move downward. The bottom end of the left sliding rod 122 is fixedly connected with a ratchet bar 125, and the bottom end of the right sliding rod 122 is fixedly connected with a ratchet bar 2 126. The end of the connecting rod 100 located outside the three-way pipe 9 is connected with a ratchet gear 127 and a ratchet gear 2 128 through a one-way clutch. The structure and principle of the one-way clutch are the existing technology. The ratchet bar 125 moves downward to engage with the ratchet gear 2 128, and the ratchet bar 2 126 moves downward to engage with the ratchet gear 1 127.

[0039] When the right fixed rod 113 and the right cover plate 114 descend, the right contact plate 124 is driven to descend together, and the right contact plate 124 contacts the right contact rod 123. When all the raw materials in the right barrel 8 flow into the preparation cylinder 3, the right contact plate 124 continues to descend and pushes the right contact rod 123 to descend, driving the right sliding rod 122 and the ratchet bar 2 126 to descend. The descending ratchet bar 2 126 will mesh with the ratchet gear 127 and make the ratchet gear 127 rotate 120 degrees clockwise. The ratchet gear 127 makes the connecting rod 100 and the connecting ball 10 rotate 120 degrees clockwise together through the one-way clutch. The connecting ball 10 becomes connected to the pipe 191, and the left barrel 8 performs the feeding work. Then the right contact plate 124 and the right cover plate 114 rise, and the right cover plate 114 pushes the right contact rod 123, so that the right contact rod 123, the right sliding bar 122 and the ratchet bar 126 rise and reset, and the ratchet gear 127 rotates counterclockwise to reset. Under the action of the one-way clutch, the connecting rod 100 and the connecting ball 10 will not rotate; similarly, when the left fixed rod 113, the left cover plate 114 and the left contact plate 124 descend, the left contact plate 124 pushes the left contact rod 123, causing the ratchet bar 125 to descend, thereby causing the ratchet gear 2 128, the connecting rod 100 and the connecting ball 10 to rotate 120 degrees counterclockwise, and the connecting ball 10 becomes connected with the pipe 2 92. When the left cover plate 114 and the left contact plate 124 rise and reset, the left contact rod 123 and the ratchet bar 125 rise and reset, and the ratchet gear 2 128 rotates clockwise alone. In summary, the connection state of the connecting ball 10 can be automatically converted after the raw material addition is completed, with high synchronization and strong process continuity.

[0040] refer to Figure 1 , Figure 2 and Fig.12 The continuous preparation device of the soil solidifier also includes a cleaning pipe 131, an electric push rod 132 and a valve stem 133. The upper part of the preparation cylinder 3 is connected with the cleaning pipe 131, and the middle part of the cleaning pipe 131 has a water inlet end 1310. The left side of the outer frame 1 is bolted with the electric push rod 132, and the telescopic rod of the electric push rod 132 is connected with the valve stem 133. The valve stem 133 is sealed and slidably connected with the cleaning pipe 131.

[0041] When there is no need to prepare soil solidifier, the water pipe is connected to the water inlet end 1310 to control the electric push rod 132 to drive the valve stem 133 to move forward, so that the valve stem 133 no longer blocks the water inlet end 1310, and water enters the preparation tube 3 through the cleaning pipe 131, so as to facilitate the cleaning of the inner wall of the preparation tube 3 to prepare the soil solidifier next time. After cleaning, the electric push rod 132 is controlled to drive the valve stem 133 to move backward and reset until the rear end face of the valve stem 133 is flush with the inner wall of the preparation tube 3 to prevent the raw materials from entering the cleaning pipe 131.

[0042] A continuous preparation method of a soil solidifying agent specifically comprises the following steps: S1: The raw materials in the right material barrel 8 enter the preparation tube 3, the servo motor is controlled to drive the spiral stirrer 4 to rotate forward, and the driving motor is controlled to make the rotating column 5 and the stirring rod 6 rotate in the opposite direction. The stirring rod 6 forms convection of the raw materials through the long strip 61 and the inclined surface 62, and the soil solidifying agent prepared in the preparation tube 3 is discharged through the discharge pipe 32; S2: While the raw materials in the preparation cylinder 3 are being prepared, the next batch of various raw materials are added sequentially into the material barrel 8 on the left; S3: When the preparation of raw materials in the preparation barrel 3 is completed, the addition of raw materials to the left barrel 8 is completed, the connecting ball 10 rotates 120 degrees clockwise, and the raw materials in the left barrel 8 enter the preparation barrel 3 for preparation. At the same time, the next batch of raw materials is added to the right barrel 8. The raw material adding process and the preparation process are carried out simultaneously.
