Abstract
Description
Technical Field
[0001] This invention relates to the field of construction equipment, and in particular to a multi-cutterhead rotary grouting and mixing head. Background Technology
[0002] With increasing environmental awareness, governments worldwide have introduced stringent environmental regulations and policies, placing higher demands on sludge treatment. These regulations require sludge treatment to meet certain environmental standards, reduce pollution, and achieve sustainable resource utilization. Traditional sludge solidification equipment suffers from relatively poor construction quality. However, with the continuous development of materials science and engineering technology, sludge solidification technology is constantly being innovated and improved. Optimization of the solidification process and improvements in construction equipment have led to continuous increases in the efficiency and quality of on-site sludge solidification.
[0003] During on-site construction, it was found that the old-style sludge solidification mixing head did not mix evenly, resulting in poor overall molding and the presence of interlayers and gaps that were not fully cured. Subsequent construction would crack and deform with the slightest disturbance, requiring rework and remixing, which increased a lot of time and economic costs. Therefore, it is necessary to use a multi-blade rotary grouting mixing head that can cut the sludge and fill the fixing material simultaneously, so as to fully mix the solidification material and the sludge. Summary of the Invention
[0004] The purpose of this invention is to overcome the defect of poor mixing effect between solidified materials and sludge by providing a multi-blade rotary grouting and mixing head.

[0007] Preferably, the grouting mechanism includes an input pipe, a universal grouting device, an internal grouting pipe, and an outlet. The universal grouting device is connected to the side wall of the bottom end of the support. The input pipe is connected to the side wall of the support. The bottom end of the input pipe is connected to the universal grouting device. The output end of the universal grouting device is rotatably connected to the internal grouting pipe. The side wall of the internal grouting pipe is connected to the side wall of the pipe hole. Multiple outlet holes are provided on the side wall of the rotating shaft and the side wall of the internal grouting pipe. The center of the outlet hole on the rotating shaft is aligned with the center of the outlet hole on the internal grouting pipe.
[0008] Preferably, the output mechanism includes a bottom tube, a first rotating groove, a first connecting rod, a first crushing roller, a first circular tube, a second circular tube, a push plate, a rotating ring, a second rotating groove, a second connecting rod, and a second crushing roller. The bottom tube is connected to the side wall of the outlet hole. The top of the bottom tube has a first rotating groove. The bottom ends of the first and second circular tubes are both connected to rotating rings. Multiple push plates are connected to the outer side walls of the first and second circular tubes. The side wall of the first rotating groove is rotatably connected to the rotating ring on the first circular tube. The top of the first circular tube has a second rotating groove. The side wall of the second rotating groove is rotatably connected to the rotating ring on the second circular tube. The inner wall of the bottom tube is connected to a first connecting rod. The side wall of the first connecting rod is connected to multiple first crushing rollers. The inner side wall of the first circular tube is connected to a second connecting rod. The side wall of the second connecting rod is connected to multiple second crushing rollers.
[0009] Preferably, the first connecting rod and the first crushing roller are both distributed inside the bottom tube and the first circular tube, and the second connecting rod and the second crushing roller are both distributed inside the first circular tube and the second circular tube.
[0010] Preferably, the outlet holes are spaced apart from the cutter head body.
[0011] Preferably, the auxiliary mechanism includes a jacking pipe, a top plate, a support rod, a support plate, a roller, and a guide plate. The top end of the second circular pipe is connected to a jacking pipe, the top end of the jacking pipe is connected to two symmetrically distributed top plates, the side wall of the top plate is connected to a support rod, the side wall of the support rod is connected to a support plate, the top end of the support plate is rotatably connected to a roller, and the bottom end of the support plate is connected to a guide plate.
[0012] Preferably, the top tube is truncated cone-shaped, and the second crushing roller at the top is located inside the top tube.
[0013] The beneficial effects of this invention are:
[0014] 1) The input pipe delivers slurry, while the hydraulic pipe provides power to the hydraulic motor. The hydraulic motor drives the rotating shaft to rotate, and the rotating shaft is connected to the slurry delivery pipe inside the shaft. Therefore, the slurry delivery pipe inside the shaft rotates synchronously, and the input pipe will input the solidified slurry into the slurry delivery pipe inside the shaft through the universal slurry feeder, and then output it into the bottom pipe through the outlet hole, thereby achieving the effect of spraying out the solidified slurry. At the same time, the rotating shaft drives the cutter head body to rotate, so that the cutter head body drives the blades to cut and tumble the sludge, so that the sludge can be simultaneously input with solidified slurry and cut and stirred, which enhances the mixing effect of solidified slurry and sludge, thereby indirectly improving the solidification effect of sludge.
[0015] 2) When the shaft rotates, it also drives the bottom tube to rotate with the shaft, which in turn causes the entire output mechanism to rotate with the shaft. The solidified slurry will flow from the outlet to the bottom tube, from the bottom tube into the first circular tube, and then into the second circular tube, and then into the sludge outside, thus achieving the effect of conveying the solidified slurry to the sludge. During the mixing, the sludge and soil lumps will collide with the push plate, which will push the first and second circular tubes to rotate. The accumulated sludge inside the first circular tube will be torn apart by the first crushing roller. Since the force pushing the push plate is different, the second circular tube will rotate relative to the first circular tube. The accumulated sludge inside the second circular tube will be torn apart by the second crushing roller, so that the solidified slurry can be sprayed out from the first and second circular tubes better.
[0016] 3) When a hard object directly hits the jacking pipe, the inclined surface of the jacking pipe can be used to make the hard object push the jacking pipe to rotate, and the jacking pipe pushes the second round pipe to rotate, thereby reducing the impact force of the hard object. When the hard object collides with the roller, it will also cause the roller to rotate, causing the hard object to change the direction of impact, thereby reducing the impact force of the hard object on the top of the second round pipe.

[0034] The connecting plate 2 and connecting rod 3 are installed on the output wall of the excavator to supply slurry to the input pipe 501.

[0036] When the rotating shaft 403 rotates, it also drives the bottom pipe 601 to rotate along with the shaft 403, thereby causing the entire output mechanism 6 to rotate with the shaft 403. The solidified slurry will flow from the outlet 504 to the bottom pipe 601, and from the bottom pipe 601 into the first circular pipe 605, and then into the second circular pipe 606, and then into the external sludge, achieving the effect of conveying the solidified slurry to the sludge.

When the first circular tube 605 and the second circular tube 606 rotate, the accumulated sludge inside the first circular tube 605 will be torn apart by the first crushing roller 604. Since the forces pushing the push plate 607 are different, the second circular tube 606 will rotate relative to the first circular tube 605. The accumulated sludge inside the second circular tube 606 will be torn apart by the second crushing roller 611, so that the solidified slurry can be better sprayed out from the first circular tube 605 and the second circular tube 606.
