Tiller hitch with adjustable plowshare angle

Abstract

The invention discloses a mini-tiller coupler capable of achieving plough share angle adjustment and belongs to the field of agricultural machinery.A connecting sleeve (6) is movably arranged on a coupling base (4) through a connecting hinge, and an angle positioning piece (8) is arranged on the connecting sleeve (6).The mini-tiller coupler is characterized in that two connecting screw holes (11) are formed in the left side and right side of the lower end of the coupling base (4) respectively, an angle adjustment screw rod (7) is movably arranged in each connecting screw hole (11), a compression spring (12) is arranged on each angle adjustment screw rod (7), and two round screw positioning holes (9) are formed in the positions, corresponds to the two angle adjustment screw rods (7), of the angle positioning piece (8).

Description

technical field [0001] The invention relates to an agricultural implement, in particular to a micro-tiller hooker with adjustable plowshare angle. Background technique [0002] My previous utility model patent: multi-function hitch for cultivator, patent number: 2015208973911, the disclosed connector, which is welded with two angle adjustment screws 7 on the hook seat 4, because the two angle adjustment screws 7 It is welded on the hanger seat 4. When the connecting sleeve 6 is adjusted in angle, the tops of the two angle adjusting screws 7 are not at one point relative to the screw positioning hole 9, so the shape of the screw positioning hole 9 is rounded. Long groove shape, in actual use, it is found that this kind of long groove hole is easy to make the nut slip off, and second, it is not as simple to process as a round hole. In addition, when adjusting, it is necessary to adjust the end of each angle adjustment screw 7. Two fixing nuts 10 are screwed on respectively. I...

Problems solved by technology

[0002] My previous utility model patent: multifunctional hitch for cultivator, patent number: 2015208973911, the disclosed connector has two angle-adjusting screw rods 7 welded on the hitch mount 4, because these two angle-adjusting screw rods 7 It is welded on the articulated seat 4. When the connecting sleeve 6 adjusts the angle, the tops of the two angle-adjusting screw rods 7 are not at a point relative to the screw rod positioning holes 9. Therefore, the shape of the screw rod positioning holes 9 is rounded. The long groove shape, found in actual use, this kind of long groove shape hole is easy to make the nut slip off, and the second is that it is not as easy to process as a round hole. Two fixed nuts 10 are screwed on respectively. During actual adjustment, the two angle-adjusting screw rods 7 need to adjust four fixed nuts 10 at the same time. No matter it is processing or adjustment, it is time-consuming and labor-intensive.
