[0030] Reference Figures 1-4 , is an embodiment of the present invention, which provides a coal drop pipe with adjustable coal drop direction, comprising:

[0031] The main body 100 includes a regulating chamber 101 and inclined chutes 102. Four groups of inclined chutes 102 are provided. The four groups of inclined chutes 102 are fixedly connected to the bottom of the regulating chamber 101. A coal inlet 101a is opened on the side wall of the regulating chamber 101.

[0032] The guide assembly 200 includes a bucket body 201, a collar 202, a guide cylinder 203, and a positioning bead 204. The bucket body 201 is disposed inside the regulating chamber 101 and is fixedly connected to the regulating chamber 101. The collar 202 is rotatably sleeved on the outside of the bucket body 201. The guide cylinder 203 is disposed below the bucket body 201 and is fixedly connected to the collar 202. The guide cylinder 203 is inclined and its bottom nozzle faces one of the groups of oblique chute pipes 102. The positioning bead 204 is disposed horizontally and is fixedly connected to the side wall of the guide cylinder 203. Four groups of positioning grooves 101b are provided inside the regulating chamber 101 to cooperate with the positioning bead 204. The positioning bead 204 is inserted into one of the groups of positioning grooves 101b.

[0033] An adjustment mechanism 300 is fixedly connected to the collar 202 and is used to adjust the rotation of the collar 202. The adjustment mechanism 300 includes a worm wheel 301 and a worm 302. The worm wheel 301 is fixedly sleeved on the outside of the collar 202. The worm 302 has a rotating shaft that passes through the adjustment chamber 101 and is rotationally connected to the adjustment chamber 101. The worm 302 and the worm wheel 301 are meshed with each other.

[0034] The bucket body 201 is located below the coal inlet 101 a , and when the positioning beads 204 are respectively inserted into the four groups of positioning grooves 101 b , the bottom pipe openings of the guide cylinder 203 are respectively facing the four groups of inclined chute pipes 102 .

[0035] In addition, the adjustment mechanism 300 further includes a handle 303 , which is disposed outside the adjustment chamber 101 and fixedly connected to the end of the rotating shaft of the worm 302 . The handle 303 is used to facilitate the rotation of the worm 302 .

[0036] It should be noted that the worm wheel 301 and the axis of the collar 202 are arranged to coincide with each other, and the handle 303 and the axis of the worm 302 are arranged to coincide with each other, to ensure the stability of the device structure, and the bottom of the guide cylinder 203 can fit with the inner wall of the bottom of the regulating bin 101, to prevent the coal from falling into other inclined chutes 102 through the gap between the guide cylinder 203 and the regulating bin 101 during transportation. The collar 202 and the guide cylinder 203 are both made of stainless steel and integrally formed. Stainless steel is corrosion-resistant, and integral forming is conducive to ensuring structural strength. The surfaces of the regulating bin 101 and the inclined chute 102 are coated with anti-corrosion paint, which is used to prevent rust. The inner walls of the regulating bin 101 and the inclined chute 102 are smooth, and the smooth inner walls are conducive to coal transportation.

[0037] Working principle: Coal enters the regulating bin 101 through the coal inlet 101a, passes through the hopper 201 and the guide cylinder 203, and then falls into a set of inclined chutes 102 facing the bottom pipe opening of the guide cylinder 203. The coal is transported through the inclined chutes 102;

[0038] When adjusting the coal conveying direction, the worm 302 is rotated by the handle 303, and the worm 302 drives the worm wheel 301 to rotate. When the worm wheel 301 rotates, it drives the collar 202 to rotate, and the collar 202 drives the guide cylinder 203 to rotate. When the guide cylinder 203 rotates, it drives the positioning bead 204 to rotate synchronously. The positioning bead 204 disengages from the corresponding positioning groove 101b. When the positioning bead 204 is facing the other set of positioning grooves 101b, the bead is stuck in the positioning groove 101b. At this time, a clicking sound can be heard and the rotation resistance of the handle 303 increases significantly. Stop rotating the handle 303. At this time, the bottom pipe mouth of the guide cylinder 203 is facing the other set of inclined chute pipes 102, and the coal conveying direction adjustment is completed.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
