Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a coal chute device with a coal material dredging mechanism, the coal chute device includes a coal breaker 100, a funnel-shaped coal chute 110, a down pipe 130 and a stirring mechanism 140, along the up-down direction, the coal chute 110 is located between the coal breaker 100 and the down pipe 130 and respectively communicates with the coal breaker 100 and the down pipe 130, the stirring mechanism 140 is connected with the down pipe 130, and at least a part of the stirring mechanism 140 is disposed at one end of the down pipe 130 close to the coal chute 110.

The inventor finds that the dropping speed of the coal material is reduced due to the fact that the cross section area of the funnel-shaped coal dropping hopper 110 is gradually reduced, when the coal material enters the descending pipe 130, the coal material is easily accumulated at the joint of the descending pipe 130 and the coal dropping hopper 110, and through the technical scheme, the stirring mechanism 140 is arranged inside one end, close to the coal dropping hopper 110, of the descending pipe 130, the falling coal material or the accumulated coal material can be scattered through the stirring mechanism 140, the coal material is effectively prevented from being accumulated at the joint of the descending pipe 130 and the coal dropping hopper 110, and therefore smooth production is guaranteed.

It should be noted that the operation cycle of the stirring mechanism 140 can be intermittent, i.e. the stirring mechanism is operated at regular time for a period of time, so that the accumulated coal can be scattered, and the connection between the downcomer 130 and the coal hopper 110 can be dredged.

Further, the number of the stirring mechanisms 140 is at least two, the at least two stirring mechanisms 140 are uniformly distributed along the circumferential direction of the downcomer 130, and the arrangement of the at least two stirring mechanisms 140 is beneficial to more widely stirring the coal entering the downcomer 130, so that the downcomer 130 is prevented from being blocked.

Referring to fig. 1 and 2, alternatively, the stirring mechanism 140 includes a driving motor 141, a first bevel gear 142, a second bevel gear 143, a stirring shaft 144, a stirring blade 145, and two supporting bearings 146, the driving motor 141 is fixedly disposed on the outer wall of the down pipe 130 and the motor shaft of the driving motor 141 extends into the down pipe 130, wherein, in order to make the driving motor 141 more stably fixed on the outer wall of the down pipe 130, the motor shaft of the driving motor 141 is perpendicular to the down pipe 130, the driving motor 141 can be fixed on the outer wall of the down pipe 130 by bolts, the two supporting bearings 146 are fixed on the inner wall of the down pipe 130 and distributed in the up-and-down direction, the stirring shaft 144 is disposed through the supporting bearings 146, the stirring shaft 144 extends in the vertical direction, the stirring blade 145 is spirally disposed and sleeved on the stirring shaft 144, the first bevel gear 142 is sleeved on the motor shaft of the driving motor 141, the second bevel gear 143 is sleeved on the stirring, therefore, when the driving motor 141 works, the driving motor 141 can drive the first bevel gear 142 to rotate, and further drive the stirring blade 145 to rotate through the second bevel gear 143, so as to break up the falling coal, thereby avoiding the blockage in the downcomer 130.

It will be appreciated that the distance between the stirring shaft 144 and the inner wall of the downcomer 130 is greater than the radius of the stirring blade 145 to avoid friction with the inner wall of the downcomer 130 when the stirring blade 145 rotates.

Further, in the radial direction of the stirring shaft 144 and the direction gradually far away from the axis of the stirring shaft 144, the thickness of the stirring blade 145 is gradually reduced, so that the outer edge of the stirring blade 145 can be formed into a blade shape, which is beneficial to crushing coal, so that the downcomer 130 is dredged and the blockage is avoided.

Further, a first inner lining plate (not shown) is disposed on the inner wall of the downcomer 130, and the support bearing 146 is fixedly mounted on the first inner lining plate, which is beneficial to enhancing the structural strength of the connection portion 120 between the downcomer 130 and the stirring mechanism 140, so as to prolong the service life of the downcomer 130. Wherein, the first lining plate can be a stainless steel plate or a wear-resistant metal plate.

Furthermore, the material receiving surface 131 of the downcomer 130 is provided with a second lining plate (not shown), and the second lining plate is provided on the material receiving surface 131 of the downcomer 130, which is beneficial for enhancing the structural strength of the downcomer 130, and the material receiving surface 131 refers to the surface on which the coal falls and can directly impact on the downcomer 130. Correspondingly, the second inner lining plate may also be a stainless steel plate or a wear-resistant metal plate. The shape of the second liner plate is adapted to the shape of the receiving surface 131 so that the second liner plate can be attached to the receiving surface 131. The second lining plate and the receiving surface 131 may be connected by welding.

further, the pitch of the stirring blade 145 gradually decreases from large to small in the falling direction of the coal. This facilitates the crushing of the coal above the stirring vanes 145, thereby enhancing the dredging effect.

Optionally, the blade width of the stirring blade 145 is 1.5-2 times the diameter of the stirring shaft 144, the blade width is too small to achieve the effect of dredging the coal material, and the blade width is too large and is easily damaged by too large impact of the coal material, so that the suitable blade width is beneficial to enhancing the dredging effect and prolonging the service life of the stirring blade 145.

Referring to fig. 1, optionally, the downcomer 130 includes a first pipe and a second pipe bent to each other, the first pipe is communicated with the coal hopper 110, the first pipe extends along a vertical direction, the second pipe extends obliquely downward, the number of the stirring mechanisms 140 includes at least two, at least one stirring mechanism 140 is disposed in the first pipe, that is, the extending direction of the at least one stirring mechanism 140 is parallel to the first pipe, the at least one stirring mechanism 140 is disposed at an end of the second pipe close to the first pipe and corresponds to the receiving surface 131 of the downcomer 130, that is, the extending direction of the at least one stirring mechanism 140 is parallel to the second pipe; the stirring mechanism 140 provided at the end of the second pipe close to the first pipe corresponds to the receiving surface 131, and this means that the stirring mechanism 140 is used to dredge the coal material deposited on the receiving surface 131. Since coal is easily accumulated in the bent portion of the downcomer 130, the dredging effect can be enhanced by providing the stirring mechanism 140.

Referring to fig. 1, further, the coal dropping pipe device with the coal dredging mechanism further includes a connecting portion 120, the connecting portion 120 is disposed between the downcomer 130 and the coal dropping funnel 110 and is respectively communicated with the downcomer 130 and the coal dropping funnel 110, and the connecting portion 120 may be a connecting flange made of polyurethane material. Thereby improving structural strength and wear resistance.
