Abstract
The utility model discloses a coal scattering and blocking prevention coal conveying and ploughing device which comprises a plough head with symmetric plough surfaces on two sides, an electric push rod, a swing frame and a door frame, wherein the door frame is arranged at the rear section of a conveying belt; the plough head is arranged over the front section of the conveying belt; coal hoppers corresponding to the plough head are arranged below two sides of the conveying belt; the plough head is mounted at the front end of the swing frame; the rear end of the swing frame is hinged to a door frame body; an electric push rod body is hinged to the top of the door frame; the front end of the electric push rod is hinged to the swing frame; horizontal diversion baffles capable of driving part of coal materials to fall into the coal hoppers are symmetrically arranged on the plough surfaces on two sides of the plough head and are perpendicular to the conveying direction; the length of each diversion baffle corresponds to the width of the conveying belt. The coal scattering and blocking prevention coal conveying and ploughing device can guide part of coal materials into the coal hoppers in advance, and the coal materials which are diverted in advance directly fall to the bottoms of the coal hoppers without colliding with the side walls of the coal hoppers, and thus the probability that coal blocks the coal hoppers or is scattered out of the coal hoppers is reduced.
Description
(1) technical field:
The utility model relates to from the equipment of belt conveyor loading and unloading material, is specially the defeated coal coal plough of a kind of anti-spillage coal anti-clogging coal.
(2) background technology:
Defeated coal coal plough, general belt plow by name, as the model electric plough type unloading apparatus that is SZC1400, applicable bandwidth 1400mm, during work, relies on the thrust of electric pushrod, triangle " colter " nutation, to belt conveyor surface, branches to coal charge in the coal breakage bucket of both sides.
During the work of described coal plough, coal stream when belt falls, can be piled up to coal breakage bucket rear portion under effect of inertia, and most of coal charge impinges upon on coal breakage bucket sidewall, and under Action of Gravity Field, turning back drops enters in the run coal bin of spiral shell coal breakage bucket bottom; In coal charge dry autumn and winter season, during transfer designs coal, work relatively normal; But in spring and summer rainy season, coal charge water ratio significantly increases, especially go up coal early stage, dump surface coal charge aqueous ingredients is very large, and free moisture, up to more than 40%, adds belt conveyor surface area water, a large amount of coal charges can be deposited in coal plough coal breakage bucket side-walls, result in blockage, when serious, spill in a large number coal outside coal breakage bucket.
In addition, due to the needs of managing, except design coal, belt conveyer is being born and is being carried other as complicated coals such as Australia coal charge, Indonesia's coal charges, and these coal viscosity are high, are also very easy to be deposited on coal breakage bucket sidewall.
For the long-pending coal of coal breakage bucket, cause and spill coaly condition, now, with artificial processing mode cleaning coal breakage bucket, to reduce obstruction, prevent from spilling coal and occur.
But no matter be that cleaning is amassed coal or spills coal, labor cleaning's work capacity is all very large.
(3) utility model content:
For the deficiencies in the prior art, the utility model proposes the defeated coal coal plough of a kind of anti-spillage coal anti-clogging coal, while mainly solving blanking, coal charge is deposited in the technical matters that coal plough coal breakage bucket side-walls results in blockage and spills coal.
The defeated coal coal plough of anti-spillage coal anti-clogging coal that can solve the problems of the technologies described above, comprise the colter with Bilateral Symmetry plough face, electric pushrod, rocker and door frame, described door frame is located at belt conveyor back segment, described colter is located at directly over belt conveyor, corresponding to colter position, in belt conveyor down either side, coal breakage bucket is set, described colter is installed on rocker front end, rocker rear end is hinged on the support body of door frame, the body of rod of described electric pushrod is hinged in door frame top, electric pushrod front end hinge rocker, on the bilateral plough face of described colter, be symmetrical arranged the shunting striker plate that can stopper divides coal charge to enter coal breakage bucket, described shunting striker plate is perpendicular to direction of transfer horizontal setting, the length of shunting striker plate is corresponding to the width of belt conveyor.
In said structure, coal charge is in coal stream mode when the colter, and part of coal stream, under the effect of shunting striker plate, falls into coal breakage bucket bottom in advance, during with coal breakage bucket sidewall collisionless, and residue coal charge normally falls into coal breakage bucket bottom.
Through observing, coal charge inertia flows distance generally at 400mm～600mm, and for this reason, described shunting striker plate is arranged on the position apart from plow tail 500mm, can meet streaming request.
The optimum position of described shunting striker plate is the 1/2 height and position place at colter.
Making adds man-hour, and described shunting striker plate can adopt 200mm angle steel to be welded on the bilateral plough face of colter.
The beneficial effects of the utility model:
1, the defeated coal coal plough of the anti-spillage coal anti-clogging coal of the utility model is under the wetter state of coal and while carrying sticky coal, the coal hopper coal blockage and spill coal probability of occurrence and significantly reduce of falling of coal plough, the long-pending coal of cleaning and spill coal work capacity and be reduced to original below 10%.
2, the utility model uses on 38 coal ploughs of applicant unit, the clearing times of coal breakage bucket is occurred 5 times～10 times by original per tour, drop to monthly 1 time～2 times, spill coal phenomenon and be substantially eliminated, greatly reduce the interval of operation and the work capacity of cleaning worker.

(5) specific embodiment:
Below in conjunction with accompanying drawing illustrated embodiment, the technical solution of the utility model is described further, the utility model mainly applies on electric plough type unloading apparatus that model is SZC1400.
The belt conveyor 5 that the defeated coal coal plough of the anti-spillage coal anti-clogging coal of the utility model is 1400mm for width (on it, coal charge stream thickness is in 300mm left and right) arranges, mainly by colter 1 (colter height 150mm), electric pushrod 2, rocker 3 and door frame 4, formed, belt conveyor 5 supports transmission (transmission direction from left to right) by carrier roller frame 8, and described carrier roller frame 8 is installed on horizontal frame 9; Along transmission direction, described door frame 4 is vertical at the back segment of belt conveyor 5, described colter 1 has bilaterally symmetric plough face (formation triangle), colter 1 (plough mouth forward) is located at directly over the leading portion of belt conveyor 5, corresponding to colter 1 position, in belt conveyor 5 down either side, coal breakage bucket 10 is set, between described colter 1 and door frame 4, rocker 3 is set, colter 1 is installed on rocker 3 front ends, rocker 3 rear ends are hinged in the support body top of door frame 4, the body of rod of described electric pushrod 2 is hinged in the top of door frame 4, electric pushrod 2 front end hinge rockers 3, as shown in Figure 1, Figure 2, Figure 3 shows.
The bilaterally symmetric plough face of described colter 1 afterbody is provided with symmetrical striker plate 7 (perpendicular to the transmission direction of belt conveyor 5 horizontally outward), and distance plough face afterbody 500mm is provided with symmetrical shunting striker plate 6, and it is highly located on 1/2 height of colter 1 plough face; Described shunting striker plate 6 selects 200mm angle steel to make, and angle steel is perpendicular to belt conveyor 5 transmission direction and be horizontally disposed with, and weld with colter 1 plough face the inner of angle steel, and the outer end of angle steel is concordant with striker plate 7, is slightly wider than belt conveyor 5, as shown in Figure 1, Figure 2, Figure 3 shows.
Operational process of the present utility model:
