DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] See also Figure 1 to Figure 10 In an embodiment of the present invention, a roadbed soft soil mixing and solidification device for adding waste fly ash for reinforcement comprises: A processing frame 1, and a mixing barrel 2 mounted on the processing frame 1, wherein the mixing barrel 2 is connected to a hopper 3 and a discharge pipe 4; Also includes: See also Figure 1-Figure 6 , a stirring mechanism is arranged in the stirring barrel 2, and a plurality of stirring blades 11 distributed equidistantly around the circumference are connected to the stirring mechanism, and a plurality of crushing grooves 1101 distributed equidistantly around the stirring blade 11 are arranged, and the stirring mechanism can drive the stirring blade 11 to rotate, and the driving mechanism includes a motor 5 installed on the processing frame 1, and a transmission rod 6 connected to the output shaft of the motor 5 is rotatably installed in the stirring barrel 2, and a driven component is arranged on the transmission rod 6, wherein the driven component includes a plurality of fixed sleeves 8 installed on the transmission rod 6 and distributed equidistantly, and a plurality of supporting sleeves 9 distributed equidistantly around the circumference are arranged on the side wall of the fixed sleeve 8, and a support rod 10 is slidably installed in the support sleeve 9, and the support rod 10 is rotatably connected with the stirring blade 11.

[0033] In detail, when stirring the soft soil, in order to increase the strength of the soft soil, it is necessary to add waste fly ash to the soft soil. Therefore, the soft soil and waste fly ash can be added into the mixing barrel 2 through the hopper 3. At this time, the motor 5 works and drives the transmission rod 6 to rotate, thereby driving the fixed sleeve 8 to move. Under the action of the fixed sleeve 8, the support sleeve 9 and the support rod 10 are driven to move, thereby driving the stirring blade 11 to rotate around the transmission rod 6. Under the action of the stirring blade 11, the soft soil and the waste fly ash are mixed and stirred.

[0034] Preferably, the motor 5 controls the rotation speed of the transmission rod 6 to be slower, thereby ensuring that the stirring blade 11 will not encounter excessive resistance due to the high viscosity of soft soil and waste fly ash during stirring, resulting in the problem of excessive load on the motor 5. A valve is provided on the discharge pipe 4. When the material is added and stirred, the valve is in a closed state. When the material stirring is completed, the valve can be opened and the material will be discharged through the discharge pipe 4.

[0035] See also Figure 3-Figure 5 , Fig. 9 , a telescopic component is arranged in the mixing barrel 2 and connected to the mixing mechanism, the telescopic component includes a rotating rod 20 rotatably installed in the mixing barrel 2 and slidably connected to the transmission rod 6, the transmission rod 6 is provided with a plurality of sliding grooves 7 equidistantly distributed, the rotating rod 20 is provided with a sliding sleeve 21 slidably connected to the sliding groove 7, the sliding sleeve 21 is slidably connected to the transmission rod 6, and a plurality of articulated rods 22 equidistantly distributed on the circumference are hinged on the sliding sleeve 21, and the articulated rod 22 is hinged to the support rod 10.

[0036] It should be noted that, in the initial state, under the action of the follow-up mechanism, the sliding sleeve 21 is located at the end of the stroke away from the fixed sleeve 8 and at the end of the stroke on one side of the slide groove 7, so that the support rod 10 is controlled by the hinge rod 22 to be located at the end of the stroke in the support sleeve 9. At this time, the distance between the stirring blade 11 and the inner wall of the stirring barrel 2 is the largest. When the transmission rod 6 rotates, the stirring blade 11 rotates around the transmission rod 6. At the same time, the transmission rod 6 will also drive the slide groove 7 to move, thereby driving the rotating rod 20 to rotate through the sliding sleeve 21. The rotating rod 20 will drive the following mechanism to move, and under the action of the following mechanism, the rotating rod 20 is controlled to slide along the length direction of the transmission rod 6. Therefore, under the action of the rotating rod 20, The sliding sleeve 21 is controlled to move along the length direction of the slide groove 7 and toward the fixed sleeve 8, so as to drive the support rod 10 to move in the direction away from the support sleeve 9 through the hinged rod 22. The support rod 10 will also drive the stirring blade 11 to move in the direction close to the inner wall of the stirring barrel 2. When the distance between the stirring blade 11 and the inner wall of the stirring barrel 2 is the smallest, under the action of the follow-up mechanism, the rotating rod 20 is controlled to move toward the initial position, so as to control the support rod 10 to move toward the support sleeve 9 again through the hinged rod 22, so that the distance between the stirring blade 11 and the inner wall of the stirring barrel 2 increases again, and the above steps are repeated, so as to realize the control of the stirring blade 11 to move around the transmission rod 6 while moving toward or away from the inner wall of the stirring barrel 2.

[0037] Preferably, since the soft soil is relatively moist, it may clump together, and the added waste fly ash may contain a certain amount of block materials therein. If it is simply stirred, it is impossible to ensure that the soft soil and the waste fly ash are mixed evenly. Therefore, in the process of controlling the stirring blade 11 to make reciprocating motion toward or away from the inner wall of the stirring barrel 2, the present application can not only continuously adjust the stirring position of the stirring blade 11 on the material to increase the stirring range while enhancing the stirring effect on the soft soil, but also when the stirring blade 11 moves toward the inner wall of the stirring barrel 2, the crushing groove 1101 cooperates with the inner wall of the stirring barrel 2 to crush and mix the clumped or block materials to ensure that the soft soil and the waste fly ash can be evenly mixed.

[0038] See also Figure 3 , Figure 4 , Fig. 9 , Fig.10 The mixing barrel 2 is also provided with a follower mechanism connected with the telescopic assembly, and the telescopic assembly can drive the follower mechanism to move when the mixing mechanism moves, so as to control the mixing blade 11 to move toward or away from the inner wall of the mixing barrel 2, and the follower mechanism includes a limit column 23 installed on the rotating rod 20, and the side wall of the mixing barrel 2 is provided with a hollow tube 24, and the hollow tube 24 is provided with a guide assembly connected with the limit column 23, wherein the guide assembly includes an annular groove 25, a first inclined groove 26, a corrugated groove 27, and a second inclined groove 28 opened on the inner wall of the hollow tube 24, and the annular groove 25, the first inclined groove 26, the corrugated groove 27, and the second inclined groove 28 are connected to each other at their ends, and the limit column 23 is slidably engaged with the annular groove 25, the first inclined groove 26, the corrugated groove 27, and the second inclined groove 28.

[0039] Specifically, the corrugated groove 27 is arranged in a wave shape, and the annular groove 25 is located at the end of the stroke away from the mixing barrel 2. In the initial state, the limit post 23 is located at the end of the stroke on the side of the annular groove 25 and the first inclined groove 26, so as to control the sliding sleeve 21 to be located at the end of the stroke away from the fixed sleeve 8 through the rotating rod 20. Under the action of the hinged rod 22, the support rod 10 is located at the end of the stroke in the support sleeve 9, so that the distance between the stirring blade 11 and the inner wall of the mixing barrel 2 is maximized. When the transmission rod 6 rotates, the rotating rod 20 will rotate synchronously, thereby driving the limit post 23 to move. The limit post 23 will disengage from the annular groove 25 and enter the first inclined groove 26, so as to control the sliding sleeve 21 to move along the length direction of the slide groove 7 through the rotating rod 20. The sliding sleeve 21 will also drive the hinged rod 22 to move, so as to control the stirring blade 11 to move toward the inner wall of the mixing barrel 2 through the support rod 10. When the limit post 2 When the stirring blade 11 moves to the connection position between the first chute 26 and the corrugated groove 27, the distance between the stirring blade 11 and the inner wall of the stirring barrel 2 is the smallest. Under the cooperation of the crushing groove 1101 and the inner wall of the stirring barrel 2, the agglomerated and blocky materials are crushed. When the limiting column 23 moves along the trajectory of the corrugated groove 27, the sliding sleeve 21 is controlled by the rotating rod 20 to slide back and forth in a small range, so as to control the stirring blade 11 to quickly reciprocate toward or away from the inner wall of the stirring barrel 2, so as to continuously crush the materials. When the limiting column 23 is separated from the corrugated groove 27 and enters the second chute 28, the rotating rod 20 is controlled to move toward the initial position, so that the stirring blade 11 moves toward the transmission rod 6. When the limiting column 23 is separated from the second chute 28 and returns to the connection position between the annular groove 25 and the first chute 26, the stirring blade 11 returns to the initial position again, and the above steps are repeated, so as to achieve the effect of continuously crushing and stirring the materials.

[0040] Preferably, by controlling the stirring blade 11 to move back and forth quickly toward or away from the inner wall of the stirring barrel 2, the effect of manually vibrating and breaking up bulk materials can be simulated, thereby ensuring that agglomerated and bulk materials can be smoothly broken and stirred.

[0041] See also Figure 3-Figure 8, an angle control mechanism is arranged on the stirring mechanism and connected to the stirring blade 11, the angle control mechanism can be activated when the stirring blade 11 moves to adjust the swing angle of the stirring blade 11, the angle control mechanism includes a limit ring 17 installed in the support sleeve 9, the circumferential outer wall of the support sleeve 9 is provided with a card slot 12, and a sliding component connected to the card slot 12 is arranged in the support sleeve 9, wherein the sliding component includes a movable ring 16 that is installed in the support sleeve 9 and is slidably connected to the card slot 12, and the movable ring 16 is in conflict with the limit ring 17 In cooperation, the movable ring 16 is provided with a movable sleeve 18 which is slidably connected to the support sleeve 9, and the movable sleeve 18 is hinged with a connecting rod 19 which is hinged to the stirring blade 11. The support rod 10 is provided with an elastic structure connected to the movable ring 16. The elastic structure mentioned above includes a support column 13 which is installed on the support rod 10 and passes through the movable ring 16. The support column 13 is provided with a spring 15, and the two ends of the spring 15 are respectively abutted against the support rod 10 and the movable ring 16. The end of the support column 13 is provided with a fixed ring 14 which abuts against the movable ring 16.

[0042] To go further, in the initial state, the limiting column 23 is located at the connection position between the annular groove 25 and the first inclined groove 26, so that the support rod 10 is located at the end of the stroke toward the support sleeve 9, so that the support column 13 and the fixed ring 14 pass through the limiting ring 17, the fixed ring 14 and the movable ring 16 are in a separated state, and the spring 15 is in a compressed state, so that the movable ring 16 abuts against the limiting ring 17. At this time, the distance between the movable sleeve 18 and the fixed sleeve 8 is the smallest. Under the action of the connecting rod 19, the angle between the stirring blade 11 and the support rod 10 is minimized. Therefore, the contact area between the stirring blade 11 and the material is maximized. When the transmission rod 6 rotates, under the action of the stirring blade 11, the soft soil and the waste fly ash are stirred and mixed. The transmission rod 6 also drives the rotating rod 20 to rotate synchronously, thereby driving the sliding sleeve 21 to move, so as to control the support rod 10 to move in the direction away from the support sleeve 9 through the hinge rod 22. , causing the stirring blade 11 to move. Since the fixed ring 14 and the movable ring 16 are in a separated state, and the spring 15 is in a compressed state, the positions of the movable ring 16 and the movable sleeve 18 will not change. Under the action of the connecting rod 19, the angle of the stirring blade 11 changes, and the support rod 10 will also drive the support column 13 to move, and drive the fixed ring 14 to move toward the movable ring 16. At this time, the spring 15 is elastically released. When the fixed ring 14 moves to the position abutting against the movable ring 16, it drives the movable ring 16 to follow the fixed ring 14 and move along the length direction of the slot 12, thereby driving the movable sleeve 18 to move. The movable sleeve 18 moves synchronously with the stirring blade 11. Therefore, the connecting rod 19 no longer controls the rotation of the stirring blade 11. At this time, the stirring blade 11 and the support rod 10 are in a vertical state, and the support rod 10 continues to move to crush the agglomerated and blocky materials through the crushing groove 1101.

[0043] Preferably, when the limiting column 23 is in the corrugated groove 27, since the fixed ring 14 and the movable ring 16 are in a fitted state, when the fixed ring 14 moves toward the limiting ring 17, it is always in fit with the movable ring 16 to ensure that the angle of the stirring blade 11 does not change. When the limiting column 23 moves into the second inclined groove 28, the support column 13 moves toward the initial position and drives the fixed ring 14 to move. Under the action of the spring 15, the movable ring 16 moves synchronously, thereby driving the movable sleeve 18 to move. At this time, the angle of the stirring blade 11 does not change. When the movable ring 16 moves to the position abutting the limiting ring 17, the movable ring 16 no longer moves, the fixed ring 14 continues to move and compresses the spring 15. When the stirring blade 11 moves, under the action of the connecting rod 19, the stirring blade 11 is controlled to swing toward the support rod 10 again to increase the contact area with the material, thereby increasing the stirring effect on the material after crushing.

[0044] A method for using a roadbed soft soil mixing and solidification device reinforced with waste fly ash, comprising the following steps: Step 1: The material to be stirred is transported into the stirring barrel 2 through the hopper 3, and the material is stirred by the stirring blades 11 under the action of the stirring mechanism; Step 2: The stirring mechanism also drives the telescopic assembly to move, and under the action of the follower mechanism, controls the stirring mechanism to move, so as to drive the stirring blade 11 to reciprocate toward or away from the inner wall of the stirring barrel 2, thereby crushing the block material through the crushing groove 1101; Step 3: When the driving mechanism moves, it also drives the angle control mechanism to move, so as to adjust the swing angle of the stirring blade 11; Step 4: After the stirring is completed, the material can be discharged through the discharge pipe 4.
