A tongue plate is connected to the front end of the bottom steel plate, and lateral U-shaped clamping plates composed of two lateral mother plates are connected on one lateral vertical baffle outward. The top of a piston of the jack is fixedly connected with the lateral U-shaped clamping plates to form auto-moving chutes. The adjacent two auto-moving chutes are in head-to-tail connection by the vertical baffles on two sides through the tail U-shaped clamping plates and bolts. A plurality of auto-moving chutes can be selected to be connected through bolts according to change of length of the fully-mechanized coal mining working face, and the working face is used with a working face scraper conveyer to form a coal flow system, and according the coal flow system of the working face is guaranteed to be smooth, and guarantee is provided for safe and efficient production of the fully-mechanized coal mining working face.
Description
Technical field
The utility model relates to a kind of overlap joint chute in the not isometric coal flow system on the down-hole combined mining working of colliery that is applied in.
Background technology
For the Inclined Full-mechanized Mining Face under the coal mine, because the work plane part is not isometric, cause can not rationally overlapping between Scraper Conveyor in Mining Face and the elevating conveyor, the work plane coal flow system has some setbacks.After work plane was elongated, Scraper Conveyor in Mining Face and lower stage loader can not directly overlap, and coal stream easily is deposited in head, and producing coal has some setbacks, and Scraper Conveyor in Mining Face easily is with later coal, and therefore damaged drag conveyor.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of fully-mechanized mining working automatic moving type chute is provided, it is applied under the coal mine, cooperating face drag conveyor forms coal flow system, smooth and easy to guarantee the work plane coal flow system, reduce staff's risk factor, the labour intensity that reduces a staff is for fully-mechanized mining working safety, High-efficient Production provide safeguard.
The utility model is that the technical solution problem adopts following technical scheme:
The design feature of the utility model fully-mechanized mining working automatic moving type chute is that a bottom steel plate is set, and is welded with respectively vertical baffle plate in the both sides of described bottom steel plate, and the afterbody of described vertical baffle plate consists of afterbody " U " clevis plate with two afterbody motherboards; Front end at the bottom steel plate connects a hyoplastron, on the vertical baffle plate of a side, is connected with toward the outer side two sidepiece motherboards and consists of sidepiece " U " clevis plate; One jack is set, and the plug of described jack masthead end alive is fixedly connected with described sidepiece " U " clevis plate, consists of the automatic moving type chute; To carry out head and the tail with the vertical baffle plate of both sides with bolt by afterbody " U " clevis plate to connect between two adjacent automatic moving type chutes.
The design feature of the utility model fully-mechanized mining working automatic moving type chute also be the vertical baffle plate of described bottom steel plate and both sides and between be welded with respectively tilt prop.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model can select polylith automatic moving type chute to connect by bolt according to the fully-mechanized mining working change in length, form coal flow system with Scraper Conveyor in Mining Face, guarantee that the work plane coal flow system is smooth and easy, for fully-mechanized mining working safety, High-efficient Production provide safeguard.
Description of drawings
Fig. 1 is the utility model structural representation;

The specific embodiment
Referring to Fig. 1, the form of structure of fully-mechanized mining working automatic moving type chute is in the present embodiment: a bottom steel plate 1 is set, is welded with respectively vertical baffle plate 2 in the both sides of bottom steel plate 1, the afterbody of vertical baffle plate 2 consists of afterbody " U " clevis plate with two afterbody motherboard 2a; Front end at bottom steel plate 1 connects a hyoplastron 3, on the vertical baffle plate 2 of a side, is connected with toward the outer side two sidepiece motherboards 4 and consists of sidepiece " U " clevis plate; One jack 5 is set, and the plug of jack 5 masthead end alive is fixedly connected with sidepiece " U " clevis plate, consists of the automatic moving type chute; To carry out head and the tail with the vertical baffle plate 2 of both sides with bolt by afterbody " U " clevis plate to connect between two adjacent automatic moving type chutes.
In the implementation, the vertical baffle plate 2 of bottom steel plate 1 and both sides and between be welded with respectively tilt prop 6.
According to the physical dimension of Scraper Conveyor in Mining Face, size length * wide * thick 1400 * 780 * 3mm of being of bottom steel plate 1 can be set; The front end of vertical baffle plate 2 is slit into circular-arc, and is slit into front end through hole 7 (as shown in Figure 2) at the front end of two risers with gas cutting respectively, so that the connection between the adjacent automatic moving type chute; Hyoplastron 3 is steel plate, and the front end of hyoplastron 3 is slit into circular-arc, and hyoplastron 3 is to form overlap joint between two adjacent automatic moving type chutes; Tilt prop 6 is steel plate, its size is long * wide * thick be 1300 * 120 * 3mm, become 30 ° of angles between tilt prop 6 and the bottom steel plate 1, its effect one is the welding of reinforcing between bottom steel plate 1 and the vertical baffle plate 2, be difficult for being smashed by large spoil, the 2nd, so that the chute that is made of bottom steel plate 1 and tilt prop 6 is a funnel type wide at the top and narrow at the bottom, make the slide coal more smooth and easy; The afterbody of four afterbody motherboard 2a is slit into circular-arc, and is slit into an afterbody through hole 8 (as shown in Figure 3) at the middle part of every afterbody motherboard with gas cutting respectively, so that the connection between the adjacent automatic moving type chute; Sidepiece motherboard 4 is of similar shape with afterbody motherboard 2a, and its afterbody is slit into circular-arc, and respectively in every sidepiece motherboard 4 to be slit into a through hole with gas cutting, the plug work masthead end that is used for being connected with jack connects; The jack cylinder body is connected with the down-hole support single, utilizes the work plane hydraulic system to realize certainly moving of chute.
Select polylith automatic moving type chute to connect by bolt according to the fully-mechanized mining working change in length, utilize the front end through hole of first chute both sides riser to be connected by the 8# iron wire with through hole on the Scraper Conveyor in Mining Face head shell, last piece chute slips along 0.2 meter apart from elevating conveyor top bottom, solve the problem that causes stagnant coal between the elongated rear Scraper Conveyor in Mining Face of fully-mechanized mining working and the elevating conveyor in the elongated zone without conveying coal equipment, and last piece chute bed hedgehopping, be higher than 0.4 meter of elevating conveyor, be convenient to coal stream and be offloaded to elevating conveyor, finish the work overlap joint between face drag conveyor and the elevating conveyor forms unobstructed coal flow system.
