Abstract
The utility model discloses an automatic ploughing depth control mechanism of a soil preparation machine. The automatic ploughing depth control mechanism of the soil preparation machine comprises a traction frame, a two-way bolt, a swinging rod, a machine frame, a pulling rod, an oil cylinder, a land wheel rotary arm, a limiting connecting rod, a land wheel, a guiding groove, a throttling valve and a pressing plate, wherein the traction frame is hinged to the front end of the machine frame, the middle of the swinging rod is hinged to the machine frame, one end of the two-way bolt is hinged to the traction frame, the other end of the two-way bolt is hinged to the end portion of the swinging rod, one end of the pulling rod is hinged to the swinging rod, the other end of the pulling rod is hinged to the land wheel rotary arm, one end of the limiting connecting rod is hinged to the land wheel rotary arm, the other end of the limiting connecting rod is installed in the guiding groove, the throttling valve is fixedly installed on the rear portion of the machine frame, and the positioning pressing plate is installed on the tail portion of the limiting connecting rod and behind the throttling valve. When the automatic ploughing depth control mechanism of the soil preparation machine works, the pressing plate is moved to a needed position to be fixed first, the machine frame descends under the action of gravity and the land wheel rotary arm rotates along with the descending of the machine frame, then the limiting connecting rod and the pressing plate are driven to move forward, and when the pressing plate is in contact with and presses the throttling valve, the throttling valve blocks an oil way and the machine frame is connected and fixed at a predetermined position, and thus the automatic control of the ploughing depth of the soil preparation machine is achieved.
Description
Technical field
The utility model belongs to a kind of farm working machinery, particularly relates to a kind of soil preparation machine tilling depth automatic controls.
Background technology
Different crops and soil condition require also inequality to the degree of depth on whole ground, so scarification equipment need carry out adjustment and the restriction of tilth when carrying out tillage operation in the farmland.Adjustment and control that existing scarification equipment carries out tilth are by the manual operation hydraulic jack, and the lifting of land wheel realizes thereby drive.The problem that above-mentioned tilling depth control mode exists is: tilth relies on range estimation, and relatively blindly, so precision is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of rational in infrastructure, workpiece is few, use reliable, easy to operate soil preparation machine tilling depth automatic controls.
In order to realize the foregoing invention purpose, the technical solution of the utility model realizes by following measure: a kind of soil preparation machine tilling depth automatic controls, comprise hitch frame, bidirectional screw, fork, frame, pull bar, oil cylinder, land wheel pivoted arm and land wheel, it is characterized in that: hitch frame and frame front end are hinged, the fork middle part is hinged with frame, bidirectional screw one end and hitch frame are hinged, the other end and swing link end part are hinged, pull bar one end and fork are hinged, the other end and land wheel pivoted arm are hinged, spacing connecting rod one end and land wheel pivoted arm are hinged, the other end is installed in the gathering sill, unidirectional stroke throttle valve is packed in the frame rear portion, and positioning pressuring plate is installed in spacing connecting rod afterbody, the back of unidirectional stroke throttle valve.
Above-mentioned soil preparation machine tilling depth automatic controls is characterized in that described positioning pressuring plate and spacing connecting rod for flexibly connecting, are installed with cock on it.
Last soil preparation machine tilling depth automatic controls is characterized in that the tailpiece of the piston rod of described oil cylinder and land wheel pivoted arm are hinged, the other end and frame be hinged.
The use the beneficial effects of the utility model are: the tilth of soil preparation machine can realize automatic control, and easy to adjust, the tilling depth precise control.
Description of drawings
Accompanying drawing 1 is front view of the present utility model.
Accompanying drawing 2 is the enlarged drawings at the utility model accompanying drawing 1 I place.
Being encoded in accompanying drawing 1 and the accompanying drawing 2: 1 is that hitch frame, 2 is that bidirectional screw, 3 is that fork, 4 is that frame, 5 is that pull bar, 6 is that oil cylinder, 7 is that land wheel pivoted arm, 8 is that spacing connecting rod, 9 is that land wheel, 10 is that gathering sill, 11 is that unidirectional stroke throttle valve, 12 is that pressing plate, 13 is cock.
Specific embodiments
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
In Fig. 1 and Fig. 2, soil preparation machine tilling depth automatic controls comprises hitch frame 1, bidirectional screw 2, fork 3, frame 4, pull bar 5, oil cylinder 6, land wheel pivoted arm 7, spacing connecting rod 8, land wheel 9, gathering sill 10, unidirectional stroke throttle valve 11, pressing plate 12, cock 13.Hitch frame and frame front end are hinged, the fork middle part is hinged with frame, bidirectional screw one end and hitch frame is hinged, the other end and swing link end part are hinged, pull bar one end and fork is hinged, the other end and land wheel pivoted arm are hinged, spacing connecting rod one end and the land wheel pivoted arm is hinged, the other end is installed in the gathering sill, unidirectional stroke throttle valve is packed in the frame rear portion, and positioning pressuring plate is installed in the back of spacing connecting rod afterbody, unidirectional stroke throttle valve, and cock is installed on the positioning pressuring plate.The tailpiece of the piston rod of oil cylinder and land wheel pivoted arm are hinged, the other end and frame are hinged.
The course of work of the present utility model is: when adjusting the soil preparation machine working depth, at first handle oil cylinder frame is risen, unscrew Luo Sai then, Luo Sai is tightened after pressing plate is moved to the position that needs, pressing plate is fixed on the spacing connecting rod.The handle of the operating hydraulically operated distributor of operator on the tractor is in " floating " position, this moment, frame began to descend under the effect of gravity together with the workpiece on it, because land wheel supports on the ground, force the land wheel pivoted arm to rotate thereupon, thereby drive spacing connecting rod reach, the pressing plate that is fixed on the spacing connecting rod moves forward thereupon, when pressing plate contacts and depresses unidirectional stroke throttle valve, unidirectional stroke throttle valve is blocked oil circuit, make frame be fixed on desired location together with the workpiece on it, thereby realized the automatic control of soil preparation machine tilth.When frame decline forces the rotation of land wheel pivoted arm, will make hitch frame with respect to angle of frame rotation by the effect of pull bar, fork, bidirectional screw, can make frame be parallel to ground, thereby make soil preparation machine front and back workpiece tilling depth unanimity.
