Adopt above-mentioned technical scheme to have following beneficial effect:
the utility model discloses drag the simple structure of the body of hanging, the U type mounting panel that the body of hanging cooperatees through U type backup pad and link has increased area of contact between them, and the round pin axle sleeve that inserts U type backup pad through the round pin axle is fixed on with the link. The structure ensures that the connection between the connecting frame and the towing body is firmer, prevents the pin shaft of the mini-tiller from loosening and the connecting frame and the towing body from shaking when the mini-tiller works, and prolongs the service life of the mini-tiller.
Three first pin shaft holes are respectively formed in the upper side plate and the lower side plate of the U-shaped supporting plate, and the connecting frame is connected with the towing body more firmly through the three pin shafts.
The following description is further described in conjunction with the accompanying drawings and the detailed description.
Drawings
Fig. 1 is a schematic structural view of the utility model;
FIG. 2 is a front view of the utility model;
FIG. 3 is a top view of FIG. 2;
fig. 4 is a schematic structural view of the connection between the trailer and the connecting frame.
In the attached drawing, 1 is a towing body, 1-1 is a connecting arm, 1-2 is a U-shaped supporting plate, 1-3 is a resistance bar fixing seat, 1-4 is a threaded hole, 1-5 is a first pin shaft hole, 1-6 is a second pin shaft hole, 2 is a connecting frame, 3 is a pin shaft sleeve, 4 is a pin shaft, and 5 is a triangular reinforcing plate.
Detailed Description
Referring to fig. 1 to 4, a trailing body of a mini-tiller is provided, which includes a connecting arm 1-1, one end of the connecting arm 1-1 is provided with a resistance rod fixing seat 1-3, the other end of the connecting arm 1-1 is provided with a U-shaped support plate 1-2 for matching with a U-shaped mounting plate of a connecting frame, the thickness of the U-shaped support plate 1-2 is greater than or equal to 6mm and less than or equal to 10mm, and in this embodiment, the thickness of the U-shaped support plate 1-2 is 6 mm. This thickness enhances the strength of the U-shaped support plate 1-2. The U-shaped supporting plate 1-2 is used for being matched with the U-shaped mounting plate of the connecting frame, a pin shaft sleeve 3 is arranged between an upper side plate and a lower side plate of the U-shaped supporting plate 1-2, at least one first pin shaft hole 1-5 is formed in the upper side plate and the lower side plate of the U-shaped supporting plate 1-2 respectively, and one first pin shaft hole 1-5 is communicated with the pin shaft sleeve 3. In the embodiment, the U-shaped supporting plate 1-2 is welded on the connecting arm 1-1 of the dragging and hanging body 1, the upper side plate and the lower side plate of the U-shaped supporting plate 1-2 are respectively provided with three first pin shaft holes 1-5, and the dragging and hanging body 1 is respectively inserted into the first pin shaft holes of the U-shaped supporting plate 1-2 through three pin shafts 4 and is connected with the connecting frame.
