And the extreme position of the downward movement of the adjusting pipe 4 is a position flush with the lower end surface of the discharging pipe 3, and the lower end surface of the discharging pipe 3 is not contacted with the lower lining plate 24.
In combination with the embodiment, when the adjusting pipe 4 is adjusted downward, the discharge holes 31 (the discharge holes 31 with larger apertures) above the lower end surface of the adjusting pipe 4 are blocked, the discharge height h is reduced, the range of the materials which can be collected by the discharge pipe 3 is reduced, and the particle size of the discharged materials is reduced; on the other hand, because the aperture of the discharge hole 31 of the upper and lower sides of the discharge pipe 3 is lower, the granularity of the material which can pass through the discharge hole 31 is also reduced, the discharge hole 31 plays a role in grading, so that a part of the material with smaller particle size can enter from the side part of the discharge pipe 3, and the efficiency of discharging can be improved under the condition of ensuring the requirement of the fineness of the discharged material. When the adjusting pipe 4 is adjusted upwards, the discharge height h is increased, the range of the materials which can be collected by the discharge pipe 3 is increased, and the granularity of the discharged materials is increased; meanwhile, a large number of discharge holes 31 with large aperture are communicated with the discharge pipe 3, and the other part of the material can enter the discharge pipe 3 through the discharge holes 31 and is finally discharged.
In this embodiment, a part of the material enters from the lower port of the discharge pipe 3 and is discharged outside through the adjusting pipe 4, and the other part of the material is discharged from the discharge hole 31 through the discharge pipe 3 and is discharged outside through the adjusting pipe 4, so that the adjusting requirement of the fineness of the discharged material can be met, and the discharging efficiency can be improved.
In a preferred embodiment, the tapping pipe 3 is fastened to the upper cover 22 by means of a mounting sleeve 7, and the control pipe 4 is screwed to the inner wall of the tapping pipe 3. The height of the adjusting pipe 4 inserted into the discharging pipe 3 can be changed by rotating the adjusting pipe 4, so that the discharging height h can be adjusted.
In a further preferred embodiment, a flange plate 40 is fixedly connected to the upper end of the adjusting pipe 4, a plurality of first jackscrews 41 are connected to the flange plate 40 in a threaded manner, and the lower ends of the first jackscrews 41 are used for being pressed against the upper end surface of the mounting sleeve 7; the upper end face of the mounting sleeve 7 is fixedly connected with a mounting support 70, a plurality of second jackscrews 71 are connected to the mounting support 70 in a threaded manner, and the lower ends of the second jackscrews 71 are used for jacking against the upper end face of the flange plate 40.
