Abstract
The utility model discloses a crushing pickaxe which comprises a power unit, a transmission speed change mechanism (2), an eccentric wheel (3), a piston (4), an air cylinder (5) and a pickaxe head (6). The crushing pickaxe is characterized in that the power unit is arranged as a gasoline engine (1). A power transmission connecting device is arranged between a rotating shaft of the gasoline engine (1) and the transmission speed change mechanism. The power transmission connecting device is mainly formed by an expansion block and an expansion disc. The transmission speed change mechanism is provided with a secondary speed change mechanism which is mainly formed by a first variable gear, a second variable gear and a third variable gear. The crushing pickaxe has the advantages of overcoming the defect in the prior art that the crushing pickaxe depends on a power supply, and being convenient to carry and suitable for being used in a workplace where the project amount is small, the work quantity is small and the power supply is far.
Description
Technical field
The utility model relates to a kind of broken field of tool for barrier-breaking in the engineering construction, relates in particular to a kind of breakup pick.
Background technology
The house tear down and build or the engineering construction such as road repair in, often to use breakup pick, to remove the obstruction that overslaugh is newly-built or repair.The breakup pick of prior art mainly is made of motor, transmission shifting mechanism, eccentric wheel, piston, cylinder and pick.Because what its actuating unit adopted is motor, so in use, must depend on power line and be connected with power supply.But many times, such as the building or keeping in repair of, highway, majority all is away from areas such as the outlying hills of power supply, mountain region, husky films, and at this moment, adopting power supply is that the breakup pick of power source just is difficult to use.If use, must carry the auxiliary equipment such as generator, air compressor machine.If engineering quantity is large, long in time limit, carry that so many auxiliary equipment still calculate than effect, if engineering quantity is little, service time is short, its cost must increase, and very calculates.Therefore, existing breakup pick is the defective of Portable belt not, caused existing breakup pick not to be suitable for away from power supply very much, and engineering quantity is little, and service time, short engineering was used.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of breakup pick, with the breakup pick that overcomes prior art Portable belt not, is not suitable for the defective of using in the engineering little away from power supply and workload.
(2) technical scheme
For achieving the above object, the utility model provides a kind of breakup pick, this breakup pick comprises power set, transmission shifting mechanism, eccentric wheel, piston, cylinder and pick, it is characterized in that, described power set are set to petrol engine, are provided with the transmission of power linkage between described petrolic rotating shaft and the transmission shifting mechanism.
As technique scheme replenish and perfect, this practical product type also has following feature:
Described transmission of power linkage master is made of expanding block and swelling dish.
Described transmission shifting mechanism is provided with two stage speed change mechanism, and described two stage speed change mechanism mainly is made of first stud gear, second stud gear and the 3rd change-speed gearing.
(3) beneficial effect
Compared with prior art, replace motor as power because the utility model is provided with take petrol engine, have easy to carryly, it is little to be more suitable for engineering quantity, and workload is little, uses away from the workplace of power supply.
Description of drawings
Fig. 1 is a kind of breakup pick structural representation of the utility model.
Shown in the figure: 1, petrol engine, 2, transmission shifting mechanism, 21, first stud gear, 22, second stud gear, the 23, the 3rd change-speed gearing, 3, eccentric wheel, 4, piston, 5, cylinder, 6, pick, 7, expanding block, 8, the swelling dish.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of breakup pick, this breakup pick mainly are made of petrol engine 1, transmission shifting mechanism 2, eccentric wheel 3, piston 4, cylinder 5 and pick 6.Be provided with the transmission of power linkage between the rotating shaft of described petrol engine 1 and the transmission shifting mechanism 2.Described transmission of power linkage master is made of expanding block 7 and swelling dish 8.Described transmission shifting mechanism 2 is provided with two stage speed change mechanism, and described two stage speed change mechanism mainly is made of first stud gear 21, second stud gear 22 and the 3rd change-speed gearing 23.
Operating principle is, the output of motor 1 is with after expanding block 7 is connected, and after the output speed of motor 1 reached certain rotating speed, under the effect of centrifugal force, expanding block 7 drove 8 rotations of swelling dishes.Swelling dish 8 orders about 21 rotations of the first gear, band movable eccentric wheel 3 rotations after the second gear 22 and the 3rd gear 23 deceleration transmission, the biasing post drivening rod of eccentric wheel 3 and piston 4 are interior reciprocating at cylinder 5, and the gas repeated stock pick under the effect of piston 4 in the cylinder 5 makes the pick work done.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
