Abstract
The utility model relates to a transversal adjustment device for the towing lug of a tractor, comprising a fixed sleeving tube, a movable towing frame, a two-way hydraulic jack or a transmission screw-thread auxiliary, a fixed clamping arm and the like. The fixed sleeving tube is tightly fixed on the towing lug of the tractor by the fixed clamping arm; one side of the movable towing frame penetrates into the fixed sleeving tube and is capable of moving freely and transversely, and the middle position of the other side is welded with the towing lug same with the towing lug of the tractor; the two-way hydraulic jack is fixed on the fixed sleeving tube; a support arm is connected with the movable towing frame (the hydraulic jack can be replaced by the transmission screw-thread auxiliary). The oil pump of the tractor drives the support arm of the two-way hydraulic jack to move telescopically; and then the telescopic movement of the support arm of the hydraulic jack drives the movable towing frame to move horizontally from left to right, thus realizing the horizontal adjustment of the relative position between the towing center of the tractor and the towing lug of the movable towing frame.
Description
Affiliated technical field
But the utility model relates to a kind of tractor-drawn device of lateral adjustments distracted position, especially the traction of agricultural machinery is regulated and can be realized intensive cultivation, Precision Seeding, improves the adaptive capacity of agricultural machinery to different terrain.
Background technology
At present, known tractor-drawn device is to constitute by being fixed on towing plate on the tractor rear axle and the traction ear on the plate, bearing pin etc.When tractor carried out agricultural operation, agricultural machinery was fixed on the traction ear by bearing pin, and the horizontal relative position of agricultural machinery and tractor is fixed, but normal operation on smooth arable land.But, when running into remote land on slope, mountain region, because of traction center of effort's point of tractor not in the center of car, because of regulating stress point, cause the ridging bending to be unfavorable for the later stage farming.When carrying out the field crops management operations, cause agricultural machinery to reduce because of adjusting distracted position with the corresponding rate of precision of ridge field crops, easily injure crop.
Summary of the invention
Can not regulate the deficiency of traction center of effort's point position in order to overcome existing tractor-drawn device, the utility model provides a kind of tractor-drawn ear lateral adjustment device, this tractor-drawn ear lateral adjustment device can not only supportingly be installed in the various agricultural machinery of traction on the various tractors, and can laterally adjust distracted position easily.
The technical scheme that its technical problem that solves the utility model adopts is: set up a tractor-drawn ear lateral adjustment device between tractor and agricultural machinery.This device is made up of fixed sleeving, movable traction framework, bidirectional hydraulic oil cylinder or motion thread pair, fixing card arm etc.Fixed sleeving is fastened on the traction ear of tractor by fixing card arm; Movable traction framework one side is through in the fixed sleeving and can laterally moves freely, and opposite side is at the center welding traction ear identical with tractor; The bidirectional hydraulic oil cylinder is fixed on the fixed sleeving, and support arm is connected (the secondary bidirectional hydraulic oil cylinder that replaces of available motion thread) with movable traction framework.Drive bidirectional hydraulic oil cylinder support arm stretching motion by the oil pump on the tractor, movable traction framework is moving by bidirectional hydraulic oil cylinder or motion thread subband, with fixed sleeving relative to laterally moving, realized the horizontal adjustment of traction ear relative position on tractor-drawn center and the movable traction framework.
The beneficial effects of the utility model are, can adjust the centre of pull position easily when the traction agricultural mechanical operation, adapt to various operating conditions, save time, laborsaving, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the axle side structural map of an embodiment of the utility model.
1. fixed sleevings among the figure, 2. movable traction framework, 3. bidirectional hydraulic oil cylinder, 4. fixing card arm, 5. traction ear, 6. cylinder support, 7. oil cylinder support arm draw back plate, 8.U shape clamp.
Embodiment
In the drawings, fix two fixing card arms 4 with U-shaped clamp 8 on the fixed sleeving 1; Fixing card arm 4 is fastened on this device on the traction ear of tractor by bearing pin; Movable traction framework 2 one sides are through in the fixed sleeving and can laterally move freely, and opposite side is at the center welding traction ear 5 identical with tractor; Bidirectional hydraulic oil cylinder 3 is fixed on the cylinder support 6 on the fixed sleeving, and support arm is connected with oil cylinder support arm draw back plate 7 on the movable traction framework 2.Drive bidirectional hydraulic oil cylinder 3 support arm stretching motions by the oil pump on the tractor, the stretching motion drive activity of oil cylinder support arm traction framework 2 and fixed sleeving be relative to laterally moving, realizes that the tractor-drawn center draws the horizontal adjustment of drawing ear 5 relative positions on the framework with movable.
Claims (1)
1. tractor-drawn ear lateral adjustment device, form by fixed sleeving, movable traction framework, bidirectional hydraulic oil cylinder or motion thread pair, fixing card arm etc., it is characterized in that: fixed sleeving and tractor-drawn ear are fastenedly connected by fixing card arm, movable traction framework is moving by bidirectional hydraulic oil cylinder or motion thread subband, with fixed sleeving relative to laterally moving.
