Abstract
The utility model provides a spiral coaling device of a cutting head type shortwall coal mining machine. The spiral coaling device mainly comprises a rear supporting leg, a motor, a shroud cylinder, a left seal receptacle, a floating seal, a right seal receptacle, a drum cover, a motor sleeve pipe, a motor sleeve pipe cover, an isolation sleeve, a splined shaft, a bearing, a shroud cylinder cover, a drum, a spline cover, a shaft end cover and bolts; the drum is provided with spiral blades; the spiral coaling device is mounted at the rear part of the cutting head type shortwall coal mining machine; the power is provided by the motor of the spiral coaling device, so that equipment traction can not be influenced, and meanwhile, the conveying efficiency that coal is pushed to a scrapping plate conveyor of the working face is further improved.
Description
Technical field
The utility model belongs to mining equipment under the coal mine, is a kind of spiral coaling gear that is specially adapted to medium and small colliery cutting hair style short-wall coal-winning machine.
Background technology
At present, under the coal mine of large and medium-sized colliery in the mining equipment cutting hair style short-wall coal-winning machine development and Design a kind of moldboard formula coaling gear.Use through actual tests; Its deficiency is: this coaling gear will cut the coal at hair style short-wall coal-winning machine rear portion; Push coal on the drag conveyor of work plane through moldboard,, will influence the equipment traction like this because thrust is the tractive force that relies on the wall coal-winning machine; The thrust that pushes away simultaneously on the drag conveyor of coal to work plane is also not enough, directly influences the coal mining transfer efficiency of coal-winning machine.
Summary of the invention
The purpose of the utility model provides a kind of compact conformation, the spiral coaling gear of the cutting hair style short-wall coal-winning machine that transfer efficiency is high to the existing problem of coaling gear of the existing cutting in medium and small colliery hair style short-wall coal-winning machine.
The technical scheme of the utility model is to achieve these goals:
A kind of spiral coaling gear that cuts the hair style short-wall coal-winning machine is characterized in that: comprise rear support leg, motor, cover tube, left seal receptacle, floating seal, right seal receptacle, drum cover, motor sleeve, motor socket cover, separation sleeve, splined shaft, bearing, cover cover, cylinder, spline lid, hubcap and bolt; Described cover tube is connected with rear support leg through bolt; Fixedly mount motor with screw bolt and nut in the cover tube; Through screw bolt and nut motor sleeve, motor socket cover are connected with motor, the motor socket cover is connected with an end of splined shaft through key, and an end of splined shaft is connected with the spline lid through spline; Through bolt drum cover is loaded on the cylinder, two dish bearings are installed between cover tube and cylinder, adorning separation sleeve between the two dish bearings, the spline lid is connected with inner flange in the cylinder through bolt; So just cylinder is contained in outside the cover tube; Described left seal receptacle is loaded on the cover tube through bolt, and right seal receptacle is loaded on drum cover through bolt, and floating seal is loaded in the left and right seal receptacle; Described axle head cover bolt is contained on the spline lid; Described cylinder is the cylinder with three helical blades, and diameter of cylinder is 540mm.
The utlity model has following advantage:
Because the spiral coaling gear has been installed at cutting hair style short-wall coal-winning machine rear portion, power is provided by self motor, so just can not influence the equipment traction, and the while has also been improved the transfer efficiency on the drag conveyor that pushes away coal to work plane.And directly improve the coal mining efficient of coal-winning machine.
The utility model is the colliery underground mining, especially realizes comprehensive mechanical coal mining for middle and small scale coal mine complete coal mining equipment is provided.
Description of drawings
Fig. 1 is the front view of spiral coaling gear;
Fig. 2 is the cylinder front view of band helical blade;
Fig. 3 is the cylinder lateral view of band helical blade.
The specific embodiment
The specific embodiment of carrying out the utility model below in conjunction with accompanying drawing specifies:
The utility model spiral coaling gear is installed on the position, the fuselage work plane side lower right corner of cutting hair style short-wall coal-winning machine, and both coal-face one side fuselage right lower quadrant was arranged with fuselage in vertical direction.
To shown in Figure 3, the spiral coaling gear comprises rear support leg 1, motor 2, cover tube 3, left seal receptacle 4, floating seal 5, right seal receptacle 6, drum cover 7, motor sleeve 8, motor socket cover 9, separation sleeve 10, splined shaft 11, bearing 12, cover cover 13, cylinder 14, spline lid 15, hubcap 16 and bolt etc. like Fig. 1.Described cover tube is connected with rear support leg through bolt; Fixedly mount motor with screw bolt and nut in the cover tube; Through screw bolt and nut motor sleeve, motor socket cover are connected with motor, the motor socket cover is connected with an end of splined shaft through key, and an end of splined shaft is connected with the spline lid through spline; Through bolt drum cover is loaded on the cylinder, two dish bearings are installed between cover tube and cylinder, adorning separation sleeve between the two dish bearings, the spline lid is connected with inner flange in the cylinder through bolt; So just cylinder is contained in outside the cover tube; Described left seal receptacle is loaded on the cover tube through bolt, and right seal receptacle is loaded on drum cover through bolt, and floating seal is loaded in the left and right seal receptacle; Described hubcap 16 usefulness bolts are contained on the spline lid 15.Cylinder is the cylinder with three helical blades, and diameter of cylinder is 540mm.
The continuous rotation through helical blade on the cylinder of coalingging in the coal cutting process of cutting hair style short-wall coal-winning machine is packed the coal under the cutterhead cut on the work plane drag conveyor into; Cutting hair style short-wall coal-winning machine is in moving back the machine process; The float coal that the spiral coaling gear will cut hair style short-wall coal-winning machine rear portion is simultaneously packed on the work plane drag conveyor, for next step pushing and sliding operation ready.
