Description

Chain is split the formula digger

The utility model belongs to plant equipment, is specifically related to a kind of chain and splits the formula digger.

Existing engineering digging is generally adopted and is bored quick-fried, shield structure, machine is adopted three kinds of methods.The moving destructive power of brill pinking is strong, and the work plane dust is excessive, and operation is difficult to guarantee safety and continuous.The shield method operation is slow, does not have speed and effectiveness, lavishes labor on.Existing machine is adopted development machine, because pick contacts excessive with broach (or planing tool) with the work ore faces, problems such as it is strong to form the body vibrations, and it is excessive to consume energy, and dust is excessive, thereby have to make body to increase power, increase volume, increase optional equipment, as dust suppression device, electromechanical equipment etc., this has just increased investment and efficient is not high, and speed is also very slow.

The purpose of this utility model solves above existing in prior technology problem with regard to being, a kind of structure uniqueness, rationally is provided, and in light weight, cost is low, effect height, but continuous operation, be convenient to control automatically and steadily, the chain of safety, cleaning splits the formula digger.

The technical solution of the utility model is to realize like this.Chain split the formula digger comprise driving part, rocking arm cutting power, rocking arm, water spray partly, a door shape cuts chain, interior water spray convex guide plate, grillage, roll and split and chain cuts the formula shovel board; vertically be connected with several grillages on the rocking arm, water spray convex guide plate in being equipped with respectively on each grillage.Door shape is cut chain and is contained on the grillage around interior water spray convex guide plate and guide wheel, and a door shape is cut chain and is made up of gate-type tingia chain sheet, intermediary's chain sheet, bearing pin and alloy knife, and gate-type tingia chain sheet links to each other with intermediary chain sheet by bearing pin, and alloy knife is located on the gate-type tingia chain sheet.The rocking arm cutting power is housed on the rocking arm, and is connected with guide wheel by the driving section.Roll that splitting distributes and be embedded in the centre position of grillage, form by two balls and the water channel that are contained in the housing.Chain cuts the formula shovel board and links to each other with driving part, chain cut the formula shovel board by output band, guide wheel, gear, cut chain and C shape plate cutting edge of a knife or a sword is formed, guide wheel partly links to each other with power through gear, cut chain and be symmetrically distributed in the front end that chain cuts the formula shovel board, C shape plate cutting edge of a knife or a sword is fixed in the front end of shovel board, and inserts door shape and cut in the slot of chain bottom.

Below in conjunction with accompanying drawing concrete structure of the present utility model is further described.

As shown in Figure 1, chain is split the formula digger and is cut chain 1, interior water spray convex guide plate 2, grillage 3 by door shape, rolls and splits 18, chain cuts compositions such as formula shovel board 10, rocking arm 7 and rocking arm cutting power 6.Vertically be connected with several grillages 3 on the rocking arm 7, water spray convex guide plate 2 in being equipped with respectively on each grillage 3, door shape is cut chain 1 and is contained on the grillage 3 around interior water spray convex guide plate 2 and guide wheel 4.Door shape is cut chain 1 and is formed (as shown in Figure 2) by gate-type tingia chain sheet 19, intermediary's chain sheet 24, bearing pin 21, alloy knife 22, and gate-type tingia chain sheet 19 links to each other with intermediary chain sheet 24 by bearing pin 21, and alloy knife 22 intervals are located on the gate-type tingia chain sheet 19.As soft loose ore bed, can increase gate-type tingia chain sheet 19 between the left and right sides blade of alloy knife 22 again, blade the forward suitably increase.The hard ore bed is then opposite, also needs to set up on blank gate-type tingia chain sheet limit material fritter, makes the blade cutting depth be no more than limit, and one protect blade, and the two reduces resistance when chain cuts operation, evenly painstaking.The bottom 23 of the bottom 20 of intermediary's chain sheet 24 and gate-type tingia chain sheet 19 will touch the last rail level 27 and the following rail level 28 of convex guide plate 2 protruding rails, gate-type tingia chain sheet 19 inboards are adjacent to the outer wall of the protruding rail of interior water spray convex guide plate 2, convex guide plate 2 is provided with high pressure water channel 25, and several spray eyes 26 (as shown in Figure 3) distribute on it.During work, the protruding rail of convex guide plate 2 is easy to scarfing cinder, in the rail level water spray make that chain cuts cooling, lubricates, cleaning and dedusting.Adopt that gate-type cuts that chain can make that cutting is stable, welding-on, accent sword have nargin, the cleaning of protection bearing pin 21.

Rocking arm cutting power 6 is contained on the rocking arm 7, and links to each other with guide wheel 4 by driving section 5.Roll and split 18 and distribute and to be embedded in the centre position of grillage 3, form by two balls 29 and the water channel 31 that are contained in the housing 30.Ball 29 can be close in the housing 30 by two onesize stainless shots and roll, and evagination 1/3 spheroid squeezes and splits (as shown in Figure 4).Split 18 centers that place grillage 3 owing to roll, stressed evenly joint-cutting two walls apply the reaction force symmetry of two steel balls simultaneously for grillage 3 when working like this, and the ball 29 that is close together rolls each other, has greatly alleviated resistance.Housing 30 includes water channel 31, and watercourse port is located between two balls 29, and by the water outlet of pearl seam, water spray is decided on the wet feelings in ore deposit, play ooze separate, lubricate, the dedusting effect.

As shown in Figure 5, grillage 3 vertically equates (being generally odd number) in groups at interval, and two row equidistant arranged evenly roll and split 18, the ball radius R on each grillage 3 ₁, R ₂, R ₃, R ₄Be and increase progressively.During work, the mineral deposit is cut chain by door shape and is cut for 1 group and be several piece, rolls to split 18 and squeeze to split in slot and roll.Because roll and split 18 being equally spaced on grillage 3, and the asynchronous distribution between the odd even grillage, make chain cut off piece except that the residual post in bottom, all pulverize and squeeze.

Chain cuts formula shovel board 10 and is with 9, guide wheel 11, gear 12, is cut chain 13 and C shape plate cutting edge of a knife or a sword 14 is formed (as shown in Figure 6) by output, and chain cuts formula shovel board 10 and can cut to sweep to roll and split 18 and squeeze broken bottom relics, and the body stable and continuous is advanced.Two arms of shovel board 10 are connected in and drive on the front axle 16, and output is located on the shovel board arm with 9 front axle 15, and output is with 9 to walk around driving front axle 16.Guide wheel 11 links to each other with power part 17 through gear 12; cut chain 13 and be symmetrically distributed in the front end that chain cuts formula shovel board 10; C shape plate cutting edge of a knife or a sword 14 is fixed in the front end of shovel board 10; and insert door shape and cut in the slot of chain 1 bottom; contact with the seam pin; can not only lift holder shovel board 10, regulate the depth of shovel board 10, and play a part to lead, protect and cut chain 13.

In addition, on power part 17, also the rocking arm lifting gear can be set.

Use this digging chain to cut the mineral deposit, it is minimum that the cutting ore faces is narrowed down to, and vibrations also drop to minimum with using power.When one group of chain cuts when cutting ore faces to several stick, roll to split and in slot, split crowdedly, the crush force that it produced is huge.In low vibrations, low power state, bring into play huge ability to work like this.

Its apparent advantage is: structure uniqueness, reasonable, in light weight, cost is low, merit Effect is high, but continuous operation, be convenient to automatically control and steadily, safety, cleaning owing to save A lot of digging optional equipments, saved a large sum of investment. The utility model is practical, and is suitable Wide with scope, be specially adapted to middle-size and small-size ore deposit and use.
