DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-4 This application is described in further detail.
[0034] To make premixed fluidized solidified soil, special equipment is required to take the soil out from underground, and then premix it with ground machinery to form premixed fluidized solidified soil slurry. After adding a certain proportion of curing agent and water, it is fully mixed evenly with ground machinery. Premixed fluidized solidified soil that is only stirred may have many bubbles inside, which reduces the bearing capacity of the premixed fluidized solidified soil and easily causes problems such as cracking.
[0035] The present application embodiment discloses a premixed fluidized solidified soil vertical mixing equipment. Figure 1 and Figure 2A vertical mixing device for premixed fluidized solidified soil includes a mixing barrel 1, which includes a top cover 2 and a barrel body 3. A handle is welded on the side of the top cover 2 away from the barrel body 3, and a socket block 22 is integrally arranged on the side of the top cover 2 close to the barrel body 3. A socket slot 33 is provided at the end of the barrel body 3 close to the top cover 2, and the socket block 22 is socket-inserted into the socket slot 33; a driving motor 21 is fixedly installed on the top cover 2, a rotating rod 31 is vertically installed in the barrel body 3, and one end of the rotating rod 31 passes through the top cover 2 and is coaxially connected to the output shaft of the driving motor 21, a stirring rod 32 is installed on the side wall of the rotating rod 31, and a vibration component 4 is installed on the stirring rod 32 and the inner wall of the barrel body 3.
[0036] When it is necessary to mix raw materials such as premixed fluidized solidified soil slurry, curing agent and water, the driving motor 21 is started, and the driving motor 21 drives the stirring rod 32 on the rotating rod 31 to rotate, thereby realizing disturbance and stirring of the premixed fluidized solidified soil slurry, curing agent and water and other raw materials. When the rotating rod 31 drives the stirring rod 32 to rotate, the reaction force exerted on the stirring rod 32 may cause relative rotation between the top cover 2 and the barrel body 3. Therefore, the socket block 22 is installed in the socket slot 33 to improve the stability of the connection between the top cover 2 and the barrel body 3, avoid relative rotation between the top cover 2 and the barrel body 3, thereby reducing the vibration effect when the protrusion 41 abuts against the rotating wheel 42. The vibration component 4 in this embodiment can cause the stirring rod 32 and the barrel body 3 to vibrate when the stirring rod 32 rotates, thereby reducing the amount of bubbles in the premixed fluidized solidified soil and improving the density and bearing capacity of the premixed fluidized solidified soil.
[0037] In order to fully mix the various raw materials such as premixed fluidized solidifying slurry, curing agent and water, refer to Figure 2 In this embodiment, multiple groups of stirring rods 32 are installed, and the multiple groups of stirring rods 32 are installed at intervals and staggered along the length direction of the rotating rod 31, further improving the stirring and mixing effect of the stirring rods 32 on raw materials such as premixed fluidized solidification slurry, curing agent and water. In this embodiment, the number of stirring rods 32 is four groups, which are installed on the rotating rod 31 by welding. In other embodiments, the number of stirring rods 32 can be adjusted according to actual needs, and the stirring rods 32 and the rotating rod 31 can be connected by threads, etc.
[0038] If only the premixed fluidized solidified soil slurry, curing agent and water are stirred and mixed, there may be many bubbles in the premixed fluidized solidified soil, which will reduce the density and bearing capacity of the premixed fluidized solidified soil and easily cause cracks in the premixed fluidized solidified soil. Figure 2 and Figure 3Therefore, the vibration component 4 in this embodiment includes multiple groups of protrusions 41, a rotating wheel 42 and an elastic member 43. An annular groove 44 is provided on the inner wall of the barrel body 3. Multiple groups of protrusions 41 are integrally and spaced apart in the annular groove 44. A sliding groove 45 is provided at the end of the stirring rod 32 away from the rotating rod 31 along the length direction of the stirring rod 32. A sliding block 46 is slidably installed in the sliding groove 45. A mounting rod 47 is welded and installed on the side of the sliding block 46 away from the rotating rod 31. The rotating wheel 42 is rotatably installed on the mounting rod 47, and the rotating wheel 42 moves in the annular groove 44. The elastic member 43 in this embodiment is installed in the mounting groove and on the side of the sliding block 46 close to the rotating rod 31. The rotating wheel 42 is elastically abutted against the protrusion 41 through the elastic member 43.
[0039] When the rotating rod 31 drives the stirring rod 32 to rotate, it drives the rotating wheel 42 to move in the annular groove 44. When the rotating wheel 42 abuts against the protrusion 41 in the annular groove 44, under the action of the reaction force of the protrusion 41 on the rotating wheel 42, the rotating wheel 42 moves in the direction of the rotating rod 31, and at the same time drives the sliding block 46 to move in the sliding groove 45 in the direction of the rotating rod 31, thereby realizing the compression of the elastic member 43. When the rotating wheel 42 is separated from the protrusion 41, under the action of the elastic member 43, the rotating wheel 42 moves in the direction away from the rotating rod 31. When the elastic potential energy of the elastic member 43 is released, the rotating wheel 42 continues to move in the annular groove 44. The abutment and separation of the rotating wheel 42 and the protrusion 41 realize the vibration effect on the stirring rod 32 and the barrel body 3, so that the premixed fluidized solidified soil in the barrel body 3 can be vibrated, thereby reducing the bubbles in the premixed fluidized solidified soil.
[0040] Reference Figure 2 and Figure 3 , multiple groups of protrusions 41 can effectively increase the contact frequency between the rotating wheel 42 and the protrusions 41, thereby improving the vibration effect on the premixed fluidized solidified soil in the barrel body 3, and further reducing the amount of bubbles in the premixed fluidized solidified soil. In this embodiment, the protrusions 41 are arranged in eight groups, and eight groups are a preferred method of this embodiment. In other embodiments, the number of protrusions 41 can be adjusted according to actual needs. In this embodiment, the elastic member 43 is a spring, and a shaping rod 48 is welded and installed on the sliding block 46. A telescopic hole 49 for the shaping rod 48 to be telescoped is provided in the stirring rod 32. The spring is sleeved and installed on the shaping rod 48. The shaping rod 48 can support the spring to prevent the spring from being greatly deformed and affecting its use. The spring is a preferred method of this embodiment. In other embodiments, a micro gas rod can be used.
[0041] When various raw materials are added into the barrel 3, some raw materials with higher density may settle at the bottom of the barrel 3. Figure 2Therefore, the spiral blades 5 are welded and installed on the side walls of the rotating rod 31 in this embodiment. When the rotating rod 31 rotates, the spiral blades 5 can drive the raw materials at the bottom to move upward, thereby further improving the mixing effect of various raw materials. In addition, the width of the spiral blades 5 in this embodiment is smaller than the radius setting of the barrel body 3, which can drive the bottom raw materials to move upward while ensuring the discharge speed of the barrel body 3.
[0042] The connection between the output shaft of the driving motor 21 and the rotating rod 31 is relatively unstable, and the output shaft of the driving motor 21 may be damaged after long-term use. Figure 2 and Figure 4 Therefore, in this embodiment, a support rod 6 is welded and installed on the inner wall of the barrel body 3, and a support plate 7 is welded and installed on the end of the support rod 6 away from the inner wall of the barrel body 3. The support plate 7 is coaxially arranged with the rotating rod 31, and a rotating groove 8 is provided on the support plate 7. The end of the rotating rod 31 away from the driving motor 21 is rotatably installed in the rotating groove 8. The support plate 7 in this embodiment can support the rotating rod 31, and the rotating groove 8 can limit the end of the rotating rod 31 away from the driving motor 21 to avoid the deviation of the end of the rotating rod 31. In this embodiment, the number of support rods 6 is four, which are welded and installed on the inner wall of the barrel body 3 at intervals. Four support rods 6 are a preferred method of this embodiment. In other embodiments, the number of support rods 6 can be adjusted according to actual needs.
[0043] Reference Figure 2 and Figure 4 In this embodiment, a bearing 9 is further installed in the rotating groove 8. The outer ring of the bearing 9 is welded to the inner wall of the rotating groove 8. A clamping groove 91 is opened on the inner ring of the bearing 9. A clamping block 311 is integrally provided at the end of the rotating rod 31 away from the driving motor 21. The clamping block 311 is installed in the clamping groove 91 to realize the clamping of the rotating rod 31 and the inner ring of the bearing 9. The bearing 9 can effectively reduce the friction between the rotating rod 31 and the rotating groove 8, thereby reducing the load of the driving motor 21 and improving the service life of the driving motor 21.
[0044] The implementation principle of a vertical mixing device for premixed fluidized solidified soil in the embodiment of the present application is as follows:
[0045] The driving motor 21 is started, and the driving motor 21 drives the rotating rod 31 and the stirring rod 32 welded on the rotating rod 31 to rotate. When the stirring rod 32 rotates, the rotating wheel 42 at the end of the stirring rod 32 away from the rotating rod 31 abuts against the protrusion 41 in the annular groove 44, so that the rotating wheel 42 moves toward the side of the mounting groove close to the stirring rod 32, and the elastic member 43 is compressed by the sliding block 46. When the rotating wheel 42 is separated from the protrusion 41, under the action of the elastic member 43, the rotating wheel 42 moves to the side of the mounting groove away from the stirring rod 32. When the elastic potential energy of the elastic member 43 is released, the rotating wheel 42 continues to move in the annular groove 44. The abutment and separation of the rotating wheel 42 and the protrusion 41 realize the vibration effect on the stirring rod 32 and the barrel body 3, so that the premixed fluidized solidified soil in the barrel body 3 can be vibrated, thereby reducing the bubbles in the premixed fluidized solidified soil.
