Abstract
The utility model belongs to agricultural machinery and relates to tall-stem crops operating machinery, in particular to a self-propelled leap-type power chassis. The self-propelled leap-type power chassis comprises a tractor body, a driving cab and a transmission system thereof, which are arranged on a machine frame equipped with wheels, wherein a direction control system and a hydraulic steering gear are arranged on the machine frame; a steering hydraulic cylinder installed on the machine frame controls steering of two wheels through a four-link mechanism; front wheels and back wheels are installed at the lower parts of a front girder and a back girder of the machine frame through supporting arms respectively; the front wheels are mainly used for supporting and steering; the back wheels are mainly used for supporting and driving; front wheel supporting arms are connected with the machine frame through a sleeve-type cross beam and are positioned by positioning and locking bolts; a hinge automatic balancing mechanism is arranged at a junction of the front cross beam and the machine frame; back wheel supporting arms are connected with a back cross beam through a U-shaped clamp; and a bidirectional tensioning mechanism is arranged on the back cross beam and can regulate bidirectional tensioning degrees in up-and-down and front-and-back directions. The self-propelled leap-type power chassis can be applied to a tall-stem crops operating machine and can be conveniently assembled into multiple kinds of operating machines.
Description
Technical field
The utility model belongs to field machine, relates to the long-stalked crop field machinery, and is particularly a kind of from walking the great-leap-forward power chassis.
Background technology
Especially indispensable job platform in corn, the contour bar crop of Chinese sorghum and woods fruit field management process of farmland from walking to cross over power machine, along with improving constantly of the continuous progress of agriculture production technology and Agricultural Mechanization Degree, the problem that original conventional high-clearance field machinery platform can not satisfy the long-stalked crop farm work is on the rise, and the intensive management in soil requires to be equipped with special-purpose large-scale Work machine.At present, field machinery commonly used to be adopted take the work tool of farm tractor vehicle frame as the basis, ground Clearance is little, facility are pulled with the many employings of trac. and are connected, overall volume is large, quality is heavy, energy consumption is high, and designing and producing all take trac. as the basis of most of work tools improved for the optimization of work tool and brought larger difficulty.At present, lack the super high-clearance that is applicable to long-stalked crop and certainly walk the great-leap-forward power chassis.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art and equipment, provides a kind of super high-clearance from walking the great-leap-forward power chassis, solves to lack practical long-stalked crop field machinery problem.
The utility model is realized by the following technical solutions: certainly walk the great-leap-forward power chassis, comprise frame, tractor body, operator's compartment, driving system, hold-down arm and the wheel etc. that travels, it is characterized in that: frame is provided with tractor body, operator's compartment, driving system, hinged autobalance and staircase.Driving system comprises sprocket wheel, chain and stretching device, front wheel supporting arm, rear wheel support arm are separately installed with front-wheel and trailing wheel, the front wheel supporting arm is connected with frame by the telescoping front cross rail, is fixed by the positioning and locking bolt, and front cross rail and frame junction are provided with hinged autobalance.Rear wheel support arm adopts the U card to be connected with after cross member, and after cross member is fixed on frame, is provided with two direction tension mechanism on after cross member, can realize the adjustment of up and down and the two-way degree of tension in front and back.Be provided with pull bar between homonymy front wheel supporting arm and rear wheel support arm, steering hardware is provided with power-assisted steering device.
Be provided with road wheel from walking the great-leap-forward power chassis, adopt the chain transmission to drive.
Be provided with hinged autobalance from walking great-leap-forward power chassis front cross rail place.
From walk on the great-leap-forward power chassis can design and installation fog system hanger bracket etc. the farmland operation parts.
Be provided with hydraulic power steering gear and operator's compartment from walking the great-leap-forward power chassis.
Can as required, staircase be set from walking the great-leap-forward power chassis.
Owing to adopting above technical scheme, the great-leap-forward power chassis of certainly walking that the utility model provides has following beneficial effect: 1, adopt and cross over from walking structure, realize automatic walking function, work tool can be installed on this chassis, be not subjected to the restriction of work tool ground Clearance, reduce the mechanical damage to long-stalked crop; 2, adopt hinged autobalance between front-wheel crossbeam and chassis, guarantee the stability of facility; 3, adopt hydraulic power steering gear, improve the direction handling quality of facility; 4, adjust before and after the stretching device on the after cross member of chassis can be realized reaching up and down, realize mechanically operated two-way tensioning.
