Specifically, the alternating stirring assembly 200 includes an electric shaft 210 arranged on the inner side of the supporting mounting frame 110, a U-shaped mounting frame 220 connected to the electric shaft 210, a first stirring barrel 230 connected to one side end of the U-shaped mounting frame 220, a second stirring barrel 240 connected to the other side end of the U-shaped mounting frame 220, and a round cover 250 connected to the first stirring barrel 230; the driving assembly 300 includes a hydraulic rod 310 on the outer side wall of the supporting mounting frame 110, a round plate 320 fixed to the top end of the hydraulic rod 310, a rotating motor 340 arranged on the surface of the round plate 320, a square plate 330 connected to the output end of the rotating motor 340, and a square hole 350 opened on the surface of the round cover 250;
[0038] During specific use, the user puts the soil and chemicals to be mixed into the first mixing barrel 230 and the second mixing barrel 240, and closes the corresponding round covers 250. At this time, the hydraulic rod 310 drives the circular plate 320 to move downward, and the circular plate 320 drives the rotating motor 340 to move. At this time, the square plate 330 and the square hole 350 fit each other, so that when the output end of the rotating motor 340 drives the square plate 330 to rotate, the square plate 330 drives one end of the first mixing barrel 230 to rotate, and at this time, the other end of the first mixing barrel 230 rotates through the rotating shaft 410. When the mixing is completed, the hydraulic rod 310 drives the rotating motor 340 to move, so that the square plate 330 is separated from the square hole 350. After the separation is completed, the electric rotating shaft 210 drives the entire U-shaped mounting frame 220 to rotate, and the positions of the first mixing barrel 230 and the second mixing barrel 240 are exchanged. The hydraulic rod 310 drives the rotating motor 340 to move, so that the rotating motor 340 drives the second mixing barrel 240 to rotate.
[0039] The adjustment assembly 400 is used to facilitate vertical unloading. Specifically, the adjustment assembly 400 includes a rectangular opening 420 opened at the front end of the U-shaped mounting frame 220, a rotating shaft 410 connected to the side end of the first mixing barrel 230, a first circular hole 430 opened at the frame position of the U-shaped mounting frame 220, a second circular hole 440 opened at the frame position of the U-shaped mounting frame 220, a first threaded rod 450 and a second threaded rod 460 arranged on the side of the U-shaped mounting frame 220, and a mounting seat 470 connected to the end of the rotating shaft 410;
[0040] The mounting seat 470 is rotatably connected to the rotating shaft 410;
[0041] During specific use, when the second mixing barrel 240 is in the process of mixing and stirring, the user removes the first threaded rod 450, at which time the mounting seat 470 rotates downward around the single second threaded rod 460, and the first mixing barrel 230 tilts downward until it is perpendicular to the base plate 120. The user unscrews the round cover 250, and the mixed soil inside the first mixing barrel 230 falls directly into the storage bin 130. The user pulls the storage bin 130, the storage bin 130 is stressed, and the slide bar 140 slides in the slide groove 150, and the storage bin 130 can be removed. After the first mixing barrel 230 has completely taken the material, the user pushes the first mixing barrel 230 upward. 30, until the first mixing barrel 230 is parallel to the base plate 120, at this time the user passes the first threaded rod 450 through the U-shaped mounting frame 220 and the mounting seat 470, and connects them with a nut, at this time the mounting seat 470 is supported and installed by the first threaded rod 450 and the second threaded rod 460, the user continues to inject the soil to be mixed into the first mixing barrel 230, so that when the second mixing barrel 240 is mixed, the square plate 330 is disengaged from the square hole 350, and the electric shaft 210 is rotated again to achieve switching, so that alternating mixing can be performed, and the next mixing can be performed without waiting for the mixed soil to be taken out, so that the mixing equipment has a higher use efficiency.
[0042] Combination Figure 1-Figure 4In the present embodiment, a stirring device for in-situ solidification treatment of soil is used. When the user puts the soil and chemical agents to be mixed into the first stirring barrel 230 and the second stirring barrel 240, and closes the corresponding round covers 250, the hydraulic rod 310 drives the round plate 320 to move downward, the round plate 320 drives the rotating motor 340 to move, and the square plate 330 and the square hole 350 fit each other. In this way, when the output end of the rotating motor 340 drives the square plate 330 to rotate, the square plate 330 drives one end of the first stirring barrel 230 to rotate. At this time, the first stirring barrel 2 The other end of the U-shaped mounting frame 220 is rotated by the rotating shaft 410. When the mixing is completed, the hydraulic rod 310 drives the rotating motor 340 to move, so that the square plate 330 is separated from the square hole 350. After the separation is completed, the electric rotating shaft 210 drives the entire U-shaped mounting frame 220 to rotate, and the positions of the first mixing barrel 230 and the second mixing barrel 240 are exchanged. The hydraulic rod 310 drives the rotating motor 340 to move, so that the rotating motor 340 drives the second mixing barrel 240 to rotate. In this way, when the second mixing barrel 240 is in the process of mixing and stirring, the user removes the first threaded rod 450. At this time, the mounting frame 220 is installed. The mounting seat 470 rotates downward around the single second threaded rod 460, and the first mixing barrel 230 tilts downward until it is perpendicular to the base plate 120. The user unscrews the round cover 250, and the mixed soil inside the first mixing barrel 230 falls directly into the storage bin 130. The user pulls the storage bin 130, and the storage bin 130 is stressed, and the slide bar 140 slides in the slide groove 150, so that the storage bin 130 can be removed. After the first mixing barrel 230 has completely taken the material, the user pushes the first mixing barrel 230 upward until the first mixing barrel 230 is parallel to the base plate 120. At this time, the user passes the first threaded rod 450 through the U-shaped mounting frame 220 and the mounting seat 470, and connects them with a nut. At this time, the mounting seat 470 is supported and installed by the first threaded rod 450 and the second threaded rod 460. The user continues to inject the soil to be mixed into the first mixing barrel 230. In this way, when the second mixing barrel 240 has completed mixing, the square plate 330 is disengaged from the square hole 350, and the electric shaft 210 rotates again to achieve switching, so that alternating mixing can be performed, and the next mixing can be performed without waiting for the mixed soil to be taken out, so that the mixing equipment has a higher use efficiency.
[0043] Furthermore, by setting the operation switching assembly 500, when the electric shaft 210 is damaged and cannot rotate, manual switching is achieved. Specifically, the operation switching assembly 500 includes a first disc 510 fixed to the top of the electric shaft 210, a round rod 520 fixed to the surface of the first disc 510, and a second disc 530 fixed to the top of the round rod 520.
[0044] The operation switching assembly 500 further includes a limiting hole 540 formed on the surface of the second disk 530 and a threaded long rod 550 penetrating the limiting hole 540;
[0045] During actual use, the user unscrews the nut that locks the threaded long rod 550, and then pulls out the threaded long rod 550. At this time, the limit between the round rod 520 and the U-shaped mounting frame 220 is lost. The operator manually moves the U-shaped mounting frame 220. At this time, the frame of the U-shaped mounting frame 220 rotates along the surface of the round rod 520. When it rotates to the required position, the user uses the threaded long rod 550 to penetrate the first disk 510 and the second disk 530 for limiting.
[0046] Furthermore, by setting up the sealing component 600, the discharge port of the mixing barrel is sealed for the second time to avoid the problem of soil leakage during the mixing process. Specifically, it also includes a sealing component 600, which includes a threaded column 610 fixed on the inner side of the round cover 250, an internal thread 620 opened on the inner side of the first mixing barrel 230, an annular raised plate 630 fixed on the bottom surface of the round cover 250, and an annular notch 640 opened on the top of the first mixing barrel 230. During specific use, the user rotates the round cover 250, and the round cover 250 drives the threaded column 610 to advance the thread inside the internal thread 620 until the annular raised plate 630 and the annular notch 640 are fitted with each other. In this way, the round cover 250 is cooperated to form a secondary seal to avoid soil leakage. When the rotating motor 340 drives the square plate 330 to rotate, the rotation direction of the square plate 330 is the same as the rotation direction of the round cover 250 when it is locked.

In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
