Abstract
The invention relates to a loading machine mechanism capable of optimizing the turnover force of a bucket. The loading machine mechanism mainly comprises a machine frame, a swing arm, a swing arm hydraulic cylinder, the bucket, a rocker arm, a cargo boom and a bucket hydraulic cylinder, wherein one end of the swing arm is connected with the machine frame and the other end of the swing arm is connected with the bucket; one end of the rocker arm is connected with the other part of the bucket and the other end of the rocker arm is connected with one end of the cargo boom; the other end of the cargo boom is connected with one part of the machine frame; the end part of a piston rod of the bucket hydraulic cylinder is connected with one part of the cargo boom; the end part of an oil cylinder of the bucket hydraulic cylinder is connected with the machine frame; the end parts of one pair of piston rods of the swing arm hydraulic cylinder are connected with the swing arm; and the end part of an oil cylinder of the swing arm hydraulic cylinder is connected with the machine frame. The loading machine mechanism has the advantages of optimizing the turnover moment of the bucket, realizing large movement range of the bucket with small driving force and reducing energy consumption.
Description
Technical field
The invention belongs to engineering machinery field, particularly a kind of loader.
Background technology
Loader is the one of engineering machinery, is widely used in the engineering fields such as building, road, mine, harbour.The Main Function of loader carries out loading operation, loading operation is by things such as sandy soil, rock, ores, pour the operation of truck, lorry, container into, certainly, loader also can realize digging operation, unloading operation, tillage operation, fill and lead up operation etc. other function a lot.Chinese patent CN1188065A discloses a kind of loader with the pivoted arm whirligig for rotating pivoted arm, effectively can prevent the upset on uneven ground of elevating conveyor traveling, but the boom that this loader controls bucket motions is connected with swing arm, the arm of force is shorter, hydraulic cylinder needs to export larger driving force could realize bucket motions, and makes bucket motions scope very limited due to the interference between swing arm and boom; Chinese patent CN 201843153 U discloses a kind of elevating conveyor reducing discharging and impact, but its boom that there is control bucket motions is equally connected with swing arm, and hydraulic cylinder needs to export the shortcoming that larger driving force could realize bucket motions.
Summary of the invention
The object of the present invention is to provide the driving force that a kind of structure is simple, energy consumption is low, use is less just can realize the mechanism of wheel loaders of the optimization scraper bowl tilting force of larger scraper bowl scope of activities.
The present invention mainly comprises frame, swing arm, swing arm hydraulic cylinder, scraper bowl, rocking arm, boom, bucket hydraulic cylinder, wherein one end of a pair swing arm is connected with frame by hinge, the other end of this swing arm is connected with a position of scraper bowl by hinge, one end of rocking arm is connected with another position of above-mentioned scraper bowl by hinge, the other end of this rocking arm is connected with one end of boom by hinge, the other end of this boom is connected with a position of frame by hinge, the end of bucket hydraulic cylinder piston rod is connected with a position below above-mentioned boom by hinge, the end of this bucket hydraulic cylinder oil cylinder is connected with the bottom of frame by hinge.The end of a pair swing arm hydraulic cylinder piston rod is connected by the middle part of hinge with above-mentioned swing arm, and the end of this swing arm hydraulic cylinder oil cylinder is connected with another position of frame by hinge.
The position that the end of the position that above-mentioned boom is connected with frame and swing arm hydraulic cylinder oil cylinder is connected with frame can exchange, and after exchanging, the end of above-mentioned bucket hydraulic cylinder piston rod is connected with a position above of above-mentioned boom by hinge.
Bucket hydraulic cylinder in the middle of above-mentioned swing arm, rocking arm, boom can change a pair bucket hydraulic cylinder be arranged symmetrically with respectively into, a pair rocking arm, a pair boom, and its annexation is identical with above-mentioned annexation.
The present invention compared with prior art tool has the following advantages:
1, the mechanical feature of loader, road obstacle clearing vehicle etc. has been merged in this mechanism, is easy to realize a tractor serves several purposes.
2, this mechanism structure is simple, has good kinematics and dynamic performance, is easy to realize real-time control.
3, can optimize the turning torque of scraper bowl, less driving force just can realize larger scraper bowl scope of activities, reduces energy consumption.
