Abstract
The utility model relates to a heading machine. The heading machine is characterized in that a cutting head and a cutting speed reducer are hinged at two ends of a telescopic tube by virtue of high-strength bolts, a cutting motor is hinged behind the cutting speed reducer, a cutting part is connected to a body frame by virtue of connecting pins, a telescopic cylinder pushes the cutting head to move forward along the telescopic tube, a shovel plate and a primary conveying device are connected with a shovel plate telescopic frame by virtue of pins, the shovel plate telescopic frame slides along a sliding box on the body frame, and a secondary conveying connecting frame is hinged on a primary conveying rear slot by virtue of the high-strength bolts. The heading machine provided by the utility model has the advantages that the stroke of the cutting part and the dinting amount of the cutting part are increased to improve the cutting rate, telescopic motion of a shovel plate part is realized, delivery quantity is increased along with increase of the telescopic amount of the cutting part, and synchronous telescopic motion of the primary conveying device and the secondary conveying device along with the shovel plate is realized, so that delivery condition of the primary conveying device is obviously improved.
Description
Technical field
The utility model relates to the mining engineering technical field, particularly a kind of development machine for coal road, coal rock tunnel and stone drifting operation.
Background technology
At present in the mine laneway excavation work, in order to alleviate the base sheet stresses concentration status, generally adopt roadway floor backfill excavated technology in circular section to replace Yuanping City's base plate tunnel excavated technology, and the development machine of existing various models and be not suitable for the excavated technology in tunnel, circular section, being mainly reflected in cutting units stroke and planted agent measures not, the shovel board width is measured not for circular arc base plate planted agent, causes shipment amount to reduce, and increases artificial shipment labour.Between first conveyor (hereinafter to be referred as a fortune) and the second conveyor (hereinafter to be referred as two fortune) owing to connectivity problem, cause falling goods, connect goods and be not in good state, one transports goods often goes out the ground situation that drops on from stock, need additionally manually to carry out secondary filling shipment, increased the danger of digging labour intensity and work.
Summary of the invention
The purpose of this utility model provides a kind of raising cutting units stroke and planted agent's amount, the development machine that anti-falling stop goods falls earthward.
The utility model is to realize like this, it comprises cutting units, shovel board section, body, Department of Transportation, cutting units is by cutterhead, extension sleeve, telescopic oil cylinder, cut reductor and cutting motor form, shovel board section is by the master, the side shovel board, star-wheel and shovel board hoist cylinder form, body is comprised of body frame and shovel board expansion bracket, Department of Transportation is by the front groove of a fortune, one fortune pit and two fortune links form, it is characterized in that: cutterhead and cut reductor are hinged on the extension sleeve two ends by high-strength bolt, cutting motor is hinged on cut reductor back, cutting units is connected on the body frame by connecting pin, telescopic oil cylinder promotes cutterhead and travels forward along extension sleeve, shovel board is connected with the shovel board expansion bracket by pin with being connected to transport, and the shovel board expansion bracket slides along the sliding case on the body frame, and two fortune links are hinged on the fortune pit by high-strength bolt.
The utility model has the advantages that cutting units stroke and cutting units planted agent amount by strengthening development machine, improve the cut rate, realized the flexible of shovel board section, cooperate the increase of cutting units stroke, improve shipment amount, realized that a fortune and two fortune follow shovel board and carry out synchronously stretching motion, thus make one transport fall the goods situation be improved significantly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described;
Fig. 1 is the structural representation of development machine,
The structural representation of Fig. 2 cut pars contractilis,
The structural representation of Fig. 3 shovel board pars contractilis,
The structural representation that Fig. 4 one fortune is connected with two fortune.
The specific embodiment
Shown in Fig. 1-4, this development machine comprises cutting units 1, shovel board section 2, body 3, Department of Transportation 4, cutterhead 5, extension sleeve 6, telescopic oil cylinder 7, cut reductor 8, cutting motor 9, main shovel board 10, side shovel board 11, star-wheel 12, shovel board hoist cylinder 13, body frame 14, shovel board expansion bracket 15, groove 16 before one fortune, one fortune pit 17, two fortune links 18, cutting units 1 is by cutterhead 5, extension sleeve 6, telescopic oil cylinder 7, cut reductor 8 and cutting motor 9 form, shovel board section 2 is by main shovel board 10, side shovel board 11, star-wheel 12 and shovel board hoist cylinder 13 form, body 3 is comprised of body frame and shovel board expansion bracket, Department of Transportation 4 is by the front groove 16 of a fortune, one fortune pit 17 and two fortune links 18 form, cutterhead 5 and cut reductor 8 are hinged on extension sleeve 6 two ends by high-strength bolt, cutting motor 9 is hinged on cut reductor 8 back, more than four parts consisted of cutting units 1, cutting units 1 is connected on the body frame 14 by connecting pin, when cutting motor 9 drives cutterhead 5 circumgyration incision operation, telescopic oil cylinder 7 can promote cutterhead 5 and travel forward along extension sleeve 6, thereby cut scope and planted agent's degree of depth of development machine have been strengthened, main shovel board 10 is connected with shovel board expansion bracket 15 by pin with being connected to transport, shovel board expansion bracket 15 slides along the sliding case on the body frame 14, realize shovel board and the synchronous elastic movement of transporter, thereby can cooperate the flexible of cut, finish smoothly completely shipment after the fragmentation, can not affect because of the cut stock operating efficiency of development machine, two fortune links 18 are broken previous design fully, with high-strength bolt be hinged on one fortune pit on 17, realized that two fortune are synchronous with stretching of a fortune, and greatly shortened one on the structure design and transported goods point and two distances of transporting the link centres of gyration, thereby reduced a goods circumference range that falls of transporting goods point, better solved the stability problem of the goods that falls.
