Description
Technical field
The utility model relates to a kind of positive backhoe switching mechanism, belongs to engineering machinery field.
Background technology
Excavator is one of topmost plant equipment in all kinds of engineer operation, can be divided into backacter and face shovel according to its shoveling mode.The feature of backacter is: " retreat downwards, force to cut soil ", is applicable to excavate the large sandy soil of water content or clay, is mainly used in shutting down the foundation ditch (groove) of below the scope of operation or the excavation of pipe trench, independent foundation ditch and side slope; The feature of face shovel is " advance upwards, force to cut soil ", and crowd shovel digging force is large, can excavate the soil in more than shutdown face, should be used for the dry foundation ditch that excavation height is greater than 2m, but must arrange up and down ramp.Two kinds of excavators respectively have feature, use all possibly according to different job requirements two kinds of excavators, therefore many engineerings excavator of all needing outfit two kinds multi-form, the wasting of resources is large, and more exchange device is often also needed in operation, very inconvenient, and some little engineerings are because of resource-constrained, are usually all only equipped with backacter, and face shovel cannot be equipped with in advance, then need when face shovel used by needs to call, not only inconvenience, also have impact on programming temporarily; If by crowd shovel and backhoe two kinds of functions based on body, then can effectively can solve the problem.
Utility model content
For solving the problem, the utility model proposes a kind of rational in infrastructure, simple operation, the positive backhoe switching mechanism that face shovel and backacter function can be integrated in one, effectively can improve resource utilization and speed up the work.
The technical scheme that the utility model adopts is: a kind of positive backhoe switching mechanism, comprise the first horn be hinged on body, and be hinged on the second horn of the first horn front end, and be hinged on the scraper bowl of the second horn front end, hydraulic stem one is connected with between the first horn and body, hydraulic stem two is connected with between second horn and the first horn, hydraulic stem three is connected with between scraper bowl and the second horn, described second horn is made up of fixed arm and the rotatable lever arm being arranged on fixed arm front end, the motor for driving lever arm 360 degree to rotate is provided with in the inside of fixed arm, described hydraulic stem three is provided with two groups, be arranged on the two ends up and down of the second horn respectively, two groups of hydraulic stems three are detachably hinged with scraper bowl.
Further, described hydraulic stem three by two main rod body and two the flexible bodies of rod being movably arranged on two main rod body front ends, and is horizontally installed on two flexible lever front ends and the telescopic cross bar that can mutually dock.
Further, the medium position at the described second upper and lower two ends of horn is equipped with the hydraulic pressure tong for fixing two groups of hydraulic stems three.
Further, described motor hydraulic motor.
Compared with prior art, it has following beneficial effect to the utility model:
Positive backhoe switching mechanism of the present utility model can change arbitrarily the direction of scraper bowl, thus make equipment be provided with the function of face shovel and backacter simultaneously, in engineer operation, effectively improve resource utilization and speed up the work, and transfer process is completed by machinery, without the need to manually dismantling, very convenient.

Detailed description of the invention
The positive backhoe switching mechanism of one as depicted in figs. 1 and 2, comprise the first horn 1 be hinged on body, and be hinged on the second horn 2 of the first horn 1 front end, and be hinged on the scraper bowl 3 of the second horn 2 front end, hydraulic stem 1 is connected with between the first horn 1 and body, hydraulic stem 25 is connected with between second horn 2 and the first horn 1, hydraulic stem 36 is connected with between scraper bowl 3 and the second horn 2, described second horn 2 is made up of fixed arm 21 and the rotatable lever arm 22 being arranged on fixed arm 21 front end, be provided with in the inside of fixed arm 21 for drive lever arm 22 can 360 degree rotate motors 23, and this motor 23 hydraulic motor, described hydraulic stem 36 is provided with two groups, is arranged on the two ends up and down of the second horn 2 respectively, and two groups of hydraulic stems 36 are detachably hinged with scraper bowl 3, described hydraulic stem 36 is by two main rod body 61 and two the flexible bodies of rod 62 being movably arranged on two main rod body 61 front ends, and be horizontally installed on two the flexible body of rod 62 front ends and the telescopic cross bar 63 that can mutually dock, hinged with it through the perforation realization at scraper bowl 3 back by two telescopic cross bar 63, this mechanism only just need can realize the power and energy of crowd shovel and backhoe by the direction of changing scraper bowl, during conversion direction, first the telescopic cross bar 63 of the hydraulic stem 36 be hinged on scraper bowl is retracted, two of this group flexible bodies of rod 62 are being retracted, scraper bowl 3 rotated to oppositely by lever arm 22 subsequently, then can conversion be completed by reverse hydraulic stem 36 with scraper bowl 3 is hinged, the medium position at described second horn about 2 two ends is equipped with the hydraulic pressure tong 7 for fixing two groups of hydraulic stems 36, and the fixing group of hydraulic stem 36 that can will retract, operates to prevent impact.
Use novel another kind of embodiment as this, described telescopic cross bar 63 can be set to fixed cross bar, by manually installing.
Positive backhoe switching mechanism of the present utility model can change arbitrarily the direction of scraper bowl, thus make equipment be provided with the function of face shovel and backacter simultaneously, in engineer operation, effectively improve resource utilization and speed up the work, and transfer process is completed by machinery, without the need to manually dismantling, very convenient.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
