Abstract
The invention relates to a multifunctional connecting frame for hand tractor, comprising a connecting board, a locating frame for farm tools, a bridging beam, a lifting lever, an adjusting device for frame height, a seat for drivers and attachments. Earth-pronging plows, cultivating plows, prongs and seed planters can be connected with the hand tractor via the connecting frame to finish various field operation. The lifting lever makes the farm tools rising and falling convenient and the adjustable machine frame makes the farm tool in best working state, therefore the utility model can increase the work efficiency and quality. The bridging beam is provided with the seat for drivers, reducing the labor strength of operators.
Description
Affiliated technical field
Agricultural machinery relates to a kind of device that uses to walking tractor matching.
Background technology
At present, China's rural area hand tractor still has certain recoverable amount, how to articulate various farm machinery, gives full play to the effect of hand tractor, remains an important problem.Known hitching frame function singleness, make existing many farm implements, all very difficult as farm machinery such as uncovering plough, intertillage plough, rake, sower and walking tractor matching, the peasant is badly in need of a kind of multi-functional hanging device, above-mentioned farm machinery can be used with walking tractor matching, and require hitching frame to control and to adjust, as the adjusting of the farm implements that rise and fall, bracket height etc., to satisfy the various requirement of agricultural production.Secondly, become and then hand tractor and walk operation and be the riding type operation, can alleviate operator's labour intensity.This project is exactly the multi-functional hitching frame for a kind of and walking tractor matching that addresses the above problem research and design.
Summary of the invention
Existing hitching frame can not articulate multiple farm implements and the deficiency of the farm implements that rise and fall in order to solve, the utility model provides a kind of multi-functional hitching frame, this hitching frame can not only articulate farm implements, and has a multiple function, utilize this hitching frame can articulate various farm implements, the farm implements that rise and fall easily, adjust the height of frame, also design the seat that the driver is arranged, the operator can handle hand tractor and farm implements easily.
The technical scheme that its technical problem that solves the utility model adopts is: a connecting plate is set in the front portion of hitching frame, the one side of this connecting plate is connected with the towing plate of bolt and hand tractor, another side is a dismountable bearing pin, connect a farm implements card frame with this bearing pin, in order to connect farm implements.Crossbeam is the member that is welded into 100 * 100 square hollow sections and steel plate.Crossbeam is provided with the lever that rises and falls, connecting rod and linking arm, and lever, connecting rod and linking arm are finished rising and falling of farm implements with rising and falling.Arc tooth plate passes from the slit of the lever that rises and falls, and is welded on the crossbeam.Rise and fall the position of lever with bayonet lock, spring, and arc tooth plate location.The bracket height guiding mechanism is connected with tail wheel, and is fixed by bolts on the crossbeam.The adjustment of the height of frame is to realize by the distance of adjusting tail wheel and frame, the principle of its guiding mechanism is as follows: the handle that rotates the tail wheel top, handle drives leading screw and rotates, nut is moved up and down, nut is welded on the quill, nut drives quill and does in sleeve and move up and down, and quill drives tail wheel again and does and move up and down, thereby has changed the distance of tail wheel and frame.Rear portion in frame is provided with operating seat, makes operating personnel can take operation.This multi-functional hitching frame is provided with the annex that connects sower, when articulating sower, can change standby annex, changes the card frame that connects farm implements, utilizes this annex can connect sower easily.
The beneficial effects of the utility model are, have solved the difficult problem that articulates of hand tractor and farm implements, and this multi-functional link can articulate multiple farm implements, finishes multiple farmland operation, and a tractor serves several purposes has been given full play to the effect of hand tractor.During farmland operation, the operator can be sitting on the seat of multi-functional hitching frame, adjusts farm implements, the farm implements that rise and fall, and has alleviated operator's manual labor.Bracket height can be adjusted, and makes farm implements be in best duty, has improved operating efficiency and operation quality.
