[0032] For those skilled in the art, it is understandable that some well-known structures in the drawings and their descriptions may be omitted. The technical solutions of the utility model are further described below in combination with the drawings and embodiments.

[0033] As Figures 1-6The utility model provides a kind of slurry stirring device for dredging of coal mine sump shown in the middle, including hopper 1, driving mechanism 2 and feeding mechanism 3.Hopper 1 is equipped with stirring mechanism 11 in the inside, and one side of hopper 1 is open end 15, and part of stirring mechanism 11 is exposed outside hopper 1 through open end 15.Driving mechanism 2 is fixedly connected with hopper 1, and driving mechanism 2 is drivingly connected with stirring mechanism 11.Driving mechanism 2 drives stirring mechanism 11 in hopper 1 to continue to operate, and hopper 1 provides the space of stirring sludge.Feeding mechanism 3 is arranged on the side of hopper 1 away from open end 15, and feeding mechanism 3 is communicated with the inside of hopper 1.Under the action of feeding mechanism 3, sludge in hopper 1 continues to operate out of coal mine sump.In working process, driving mechanism 2 drives stirring mechanism 11 to rotate in hopper 1, and sludge in the bottom of coal mine sump is continuously transported to the inside of hopper 1.Because one side of hopper 1 is open end 15, sludge is smoothly entered into the inside of hopper 1 under the impulsion of stirring blade 114.Stirring mechanism 11 not only plays the role of conveying, but also can fully stir sludge, prevent it from depositing and caking, and ensure slurry fluidity.Closed side of hopper 1 is connected with feeding mechanism 3, and feeding mechanism 3 can adopt screw conveyor, pumping system or belt conveying device, and sludge after stirring is continuously operated out of sump, to realize efficient dredging.

[0034] Stirring mechanism 11 includes stirring blade 114 and stirring shaft 111, and stirring blade 114 is located in the inside of hopper 1, and the rotation center of stirring blade 114 is equipped with stirring shaft 111.Both ends of stirring shaft 111 pass through hopper 1, and are equipped with driven wheel 112 drivingly connected with driving mechanism 2.From driven wheel 112 can be drivingly connected with transmission mechanism through belt or chain.Driving mechanism 2 drives stirring mechanism 11 to rotate, and stirring blade 114 is stirred in the process of rotation, on the one hand, sludge in hopper 1 is stirred, to prevent it from depositing and caking, and on the other hand, since blade is arranged in spiral or inclination, sludge can be pushed to the open end 15 of hopper 1, to smoothly enter into the inside of hopper 1.With the continuous operation of stirring mechanism 11, sludge is fully mixed in hopper 1, and is discharged from coal mine sump through feeding mechanism 3, to complete dredging work.

[0035] The driving mechanism 2 comprises a stirring motor 21 and a transmission rod 22. The stirring motor 21 is in transmission connection with the transmission rod 22. The output end of the stirring motor 21 is provided with a gear box 211, and the gear box 211 is provided with a shaft sleeve 212 matched with the transmission rod 22. The output shaft of the stirring motor 21 is provided with a second bevel gear at one end of the gear box 211, and the transmission rod 22 is provided with a first bevel gear 221 matched with the second bevel gear. The stirring motor 21 and the transmission rod 22 form a stable transmission relationship through the cooperation of the first bevel gear 221 and the second bevel gear. The first bevel gear 221 is located in the middle of the transmission rod 22, and the two ends of the transmission rod 22 are provided with driving wheels 222 corresponding to the two sides of the stirring mechanism 11. The driving wheels 222 are provided with transmission chains 113, and the driving wheels 222 are in transmission connection with the driven wheels 112 of the stirring mechanism 11 through the transmission chains 113.

Through the adoption of double-side chain transmission, the stress of the stirring mechanism 11 is more balanced, and the problems of unbalanced load or jamming caused by single-side driving are avoided, so that the stirring process is stable and efficient. At the same time, the double-side chain transmission can make the two sides of the stirring mechanism 11 bear the force evenly, reduce the eccentric wear of the stirring shaft 111, and prolong the service life of the equipment; the double-side transmission can share the load, reduce the risk of single-side motor overload, and save energy.

[0036] The driving mechanism 2 is provided with a support plate 13 on the side close to the open end 15. The support plate 13 is integrated with the hopper 1, and the driving mechanism 2 is fixedly connected with the support plate 13. The support plate 13 provides a fixing point for the driving mechanism 2 on the hopper 1, and improves the stability of the driving mechanism 2 on the hopper 1. The sludge flow frequency of the open end 15 is high, and the support plate 13 forms an isolation protection on one side of the driving mechanism 2 to prevent the driving mechanism 2 from being in contact with the sludge and causing abnormal work of the driving mechanism 2 during the process of the sludge entering the open end 15.

[0037] The part of the open end 15 corresponding to the stirring mechanism 11 exposed to the outside of the hopper 1 is provided with a protective fence 12. A part of the stirring blades 114 of the stirring mechanism 11 passes through the open end 15 and is exposed to the outside of the hopper 1 to directly contact with the sludge. The protective fence 12 can block large stones in the sludge from approaching the open end 15, prevent the large stones from damaging the running stirring blades 114, and also prevent the stones from entering the hopper 1 to cause material blockage, which is beneficial to maintaining the fluidity of the sludge in the hopper 1. The edge of the protective fence 12 is fixedly connected with the edge of the open end 15 through fasteners. By installing or dismounting the fasteners, the protective fence 12 can be installed or dismounted, which is convenient for equipment maintenance or component replacement.

The barrel 31 is provided with a discharge port 311 at the end close to the feeding motor 32, and the discharge port 311 communicates the inside of the barrel 31 and the outside pipeline. The output end of the feeding motor 32 is provided with a feeding shaft 33, the feeding shaft 33 is located in the inside of the barrel 31 and is distributed along the length direction of the barrel 31, and the circumferential direction of the feeding shaft 33 is provided with spiral blades 331, and the spiral blades 331 are distributed along the length direction of the feeding shaft 33. The feeding motor 32 drives the feeding shaft 33 to rotate, the feeding shaft 33 drives the spiral blades 331 to rotate, and the sludge in the hopper is transported along the length direction of the barrel 31 under the action of the spiral blades 331, and is transferred from the hopper to the discharge port 311, so that the sludge transfer and transportation are completed. The spiral blades 331 are provided with a plurality of second permeation holes 332 which are arrayed and distributed, the bottom of the hopper 1 is provided with a plurality of first permeation holes 14 which are arrayed and distributed, and the first permeation holes 14 communicate the inside of the hopper 1 and the outside. The sludge moves along the length direction of the barrel 31 under the extrusion action of the spiral blades 331, and the water in the sludge is permeated through the second permeation holes 332, so that the working load of the feeding mechanism 3 is reduced. The permeated water flows back into the hopper 1 along the barrel 31, and flows out of the hopper 1 through the first permeation holes 14.

[0039] The working principle of the utility model is: the hopper 1 is inserted into the coal mine water warehouse, the stirring motor 21 is driven, and the stirring mechanism 11 in the hopper 1 rotates under the driving of the stirring motor 21. The rotating stirring blades 114 continuously pass through the open end 15 in the sludge in the coal mine water warehouse, and the sludge enters the hopper 1. The feeding motor 32 drives the feeding shaft 33 to rotate, the feeding shaft 33 drives the spiral blades 331 to rotate, and the sludge in the hopper 1 continuously moves along the length direction of the barrel 31 under the action of the spiral blades 331 and finally flows out of the discharge port 311.
