Abstract
The utility model relates to a digging machine, which is to solve the problems of unstable power output, weak environmental adaptation. The digging machine mainly comprises a diesel engine and a gearbox connected therewith, wherein the gearbox outputs in two circuits: one is connected with a car bridge via a transmission shaft; the other is connected with a hydraulic pump via a gear power case. The utility model has compact structure, reliable transmission, lowered manufacturing cost, reduced manufacturing period and improved service life of products.
Description
The utility model relates to excavator equipment, specially refers to a kind of mini-excavator actuating unit.
In background technology, referring to Fig. 2, the power transmission of traditional mini-excavator is by the 12 output two-way of engine belt pulley in the diesel engine, the power transmission shaft 10 that self connects of leading up to connects hydraulic pump 9, another road connects vehicle bridge 11 by negative pulley wheel 13, gearbox 12, power transmission shaft 10, extend to skid and influence the output of power because belt transmission easily produces heating, belt, make this product on the hills, the use in area, mountain area is subjected to great restriction.
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, develop a kind of mini-excavator actuating unit, solve power and export influenced problem of unstable, improve product application life, reduce cost, enlarge and adapt to the scope of application of different severe environments.
Technical solution of the present utility model is as follows:
Comprise: gearbox (2) connects vehicle bridge (11) through power transmission shaft (10), it is characterized in that: diesel engine (1) output connects gearbox (2), gearbox (2) output two-way, one the tunnel through power transmission shaft (10) connection vehicle bridge (11), another road connects hydraulic pump 9 through gear transmission case (3), and clutch lever (8) connects the gear shaft (7) in the headstock (3).
Technical solution of the present utility model also comprises: headstock (3) middle gear axle (7) is gone up assembling gear (4) and duplex bearing (6), and hydraulic pump (9) is connected with the gear shaft that gear (4) is meshed.
Advantage of the present utility model and effect are as follows:
(1) owing to replaced belt transmission structure with gear drive, so whole apparatus structure compactness, reliable transmission has overcome the problem that former transmission slip produces heating.
(2) the total compactness greatly reduces cost of production, has shortened the production cycle, has improved product application life.
(3) enlarge the scope of application of this machine, improved the functional performance under the various adverse circumstances.
Description of drawings of the present utility model is as follows: Fig. 1 is the total schematic diagram, and Fig. 2 is the background technology overall schematic, and number in the figure is described as follows: the 1-diesel engine, the 2-gearbox, 3-headstock, 4-gear, the 5-spacer, 6-duplex bearing, 7-gear shaft, the 8-control stick, the 9-hydraulic pump, 10-power transmission shaft, 11-vehicle bridge, the 12-engine belt pulley, the 13-negative pulley wheel.
Following adjoint is described in further detail: referring to Fig. 1, diesel engine 1 is as power source, export to gearbox 2, gearbox 2 output two-way, the one tunnel through power transmission shaft 10 connection vehicle bridge 11, another road connects hydraulic pump 9 through headstock 3, gear shaft 7 is housed in the headstock 3, gear 4, cover 5 and duplex bearing 6 are housed on it, control stick 8 connects the clutch that gear shaft 7 is realized power, hydraulic pump 9 is connected with the gear shaft that gear 4 is meshed, and gear 4 is passed to hydraulic pump 9 to power.Fig. 2 states, no longer statement.
Claims (2)
1, mini-excavator actuating unit, comprise: gearbox (2) connects vehicle bridge (11) through power transmission shaft (10), it is characterized in that: diesel engine (1) output connects gearbox (2), gearbox (2) output two-way, one the tunnel through power transmission shaft (10) connection vehicle bridge (11), another road connects hydraulic pump 9 through gear transmission case (3), and clutch lever (8) connects the gear shaft (7) in the headstock (3).
2, mini-excavator actuating unit according to claim 1, it is characterized in that: technical solution of the present utility model also comprises: headstock (3) middle gear axle (7) is gone up assembling gear (4) and duplex bearing (6), and hydraulic pump (9) is connected with the gear shaft that gear (4) is meshed.
