Abstract
The invention discloses a coal cutter drum with wear-resistant ultrasonic cutting picks. The coal cutter drum with the wear-resistant ultrasonic cutting picks comprises a coal cutter drum body and cutting pick bodies, wherein the cutting pick bodies are mounted on the coal cutter drum body through cutting pick seats; an ultrasonic transmitting device is arranged at the rear end of each cutting pick main body; the front end of each cutting pick main body is a pick head; the pick heads are conical crowns; a plurality of convex threads with consistent screwing directions are uniformly distributed on the lower portion of each pick head; the upper ends of the convex threads are small while the lower ends of the convex threads are large; and equidistant concave threads with consistent screwing directions are formed among the convex threads. Shortcomings in the prior art are overcome, the convex threads are arranged at the upper ends of the cutting pick bodies, by the convex threads, the circumstances that a certain portion of a working face of the head of each coal cutting pick is always in contact with a rock wall and is abraded, and the coal cutting pick is broken are avoided, the concave threads can serve as channels for dissipating heat, discharging rock powder and discharging gas, moreover, the ultrasonic transmitting devices are arranged at the rear ends of the cutting pick bodies, and the cutting effect, structural stability and reliability are improved.
Description
Technical field
The present invention relates to production facility of coalmine technical field, specifically belong to a kind of coal mining machine roller being provided with corrosion-resistant ultrasonic wave pick.
Background technology
Current underground mine widely uses development machine and coal-winning machine carries out mining operations, and pick is the conventional cutting means of mining machinery.The pick that mining machinery uses all is mounted on the cylinder of coal-winning machine or development machine, drives pick to do uniform rotation together during digging operation by cylinder, by pick to the pressure of coal petrography, cut for realizing broken coal petrography.Research shows that most of power of mining machinery all consumes on the cutting action of its pick, and therefore the condition of work of pick is extremely severe, is the pole easily worn part of mining machinery.And improving constantly along with modern mining machinery power, the impact of bearing of its pick is often excessive, effectively cut cannot be carried out when particularly running into hard rock in mining work activities process, the wearing and tearing of its pick are abnormal serious, constrain reliability and the operating efficiency of the continuous service of mining machinery; The head also having mining hard alloy coal cutting teeth is cone or half ball-crown body, when cutting rock stratum in coal cutting crown incision rock stratum, tooth head is airtight by rock stratum, tooth head temperatures as high about 500 DEG C, rock dust is current cannot discharge, water spray on pick toothholder cannot spray and crown, therefore the wearing and tearing of pick crown are large, quick abrasion, and easily collapse tooth, the product operating period is short, and production efficiency is low, causes the waste of China's resources of production particularly strategic tungsten resource.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of coal mining machine roller being provided with corrosion-resistant ultrasonic wave pick, overcome the deficiencies in the prior art, in cutting pick body upper end, convex thread is set, convex thread can be avoided certain part of coal cutting teeth head work plane to contact with crag being all the time worn, causing coal cutting teeth to rupture; Recessed screw thread can as the passage of heat radiation, row's rock dust, gas-removing gas, and cutting pick body rear end is provided with ultrasonic transmitter simultaneously, increases cutting effect, structural stability and reliability.
The technical solution used in the present invention is as follows:
A kind of coal mining machine roller being provided with corrosion-resistant ultrasonic wave pick, coal mining machine roller and cutting pick body, cutting pick body is arranged on coal mining machine roller by pick box, described cutting pick body rear end is provided with ultrasonic transmission device, cutting pick body front end is tooth head, and described tooth head is circular cone hat body, and tooth head bottom is evenly equipped with the consistent convex thread of multiple rotation direction, described convex thread is big top and small bottom, forms the equidistant recessed screw thread that rotation direction is consistent between convex thread.
Described cutting pick body forms leading section by two sections and rearward end is threaded connection, and described cutting pick body leading section and rearward end junction are provided with pick box.
Described cutting pick body leading section and rear end, rearward end junction form cannelure, and form oil pocket between cannelure and pick box inside, described cutting pick body rearward end is provided with tank filler sleeve.
Described convex thread is 3 ~ 4cm apart from the distance in tooth crown portion.
Described cutting pick body rearward end is provided with anti-explosion cover, and anti-explosion cover is threaded with cutting pick body rearward end.
Described cutting pick body rearward end has outward extending part, is provided with resilient rubbber cushion between described outward extending part and pick box.
Resilient rubbber cushion is provided with between described tooth head and pick box.
Compared with the prior art, beneficial effect of the present invention is as follows:
The principle of ultrasonic amplitude transformer is incorporated in the pick design of mining machinery by the present invention, utilize hyperacoustic high frequency micro vibration smashing principle to strengthen the cut crushing efficiency of hard rock, its amplitude is unlikely to the significantly vibration causing mining machinery cantilever or rocking arm simultaneously, does not affect overall work stability and the reliability of mining machinery; Cutting pick body arranges convex thread, convex thread is when the lasting opposing being subject to rock stratum crag is impacted and extruded, whole pick threadingly rotation direction rightabout axial rotation in toothholder nest on cylinder will be driven, certain part of coal cutting teeth head work plane can be avoided to contact with crag be all the time worn, cause coal cutting teeth to rupture; Recessed screw thread can as the passage of heat radiation, row's rock dust, gas-removing gas, the dust water that Absorbable rod toothholder sprays, protection coal cutting teeth crown cutting rock stratum efficiency at low temperatures and the overall wear resistance of coal cutting teeth.
