Description

Reverse folding spray boom frame of plant protection sprayer

Technical Field

The utility model relates to a plant protection sprayer spray boom frame, more specifically say, relate to a plant protection sprayer reverse folding spray boom frame.

Background

The self-propelled spray rod type plant protection spraying machine is main equipment for spraying liquid medicine for crop plant protection, and in order to meet the requirement of wide-range efficient operation, a spray rod frame provided with a spray head is wide enough. However, the large-width spray rod frame is inconvenient to maneuver and transfer in the field, the increase of the operation width is limited, the existing folding spray rod frame mechanism is too complex in design, and the working reliability cannot meet the requirement.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists, provide a plant protection sprayer reverse folding spray lance frame that simple structure, reliability are high.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model relates to a reverse folding spray rod frame of a plant protection spraying machine, which comprises a main frame, a main frame seat, a tail frame seat, a folding oil cylinder, an upper oblique beam, a swing rod and a connecting rod, an upper oblique beam is arranged above the main frame, the upper oblique beam and the horizontal beam of the main frame form a triangular truss, the intersection end of the upper oblique beam and the horizontal beam of the main frame is provided with a main frame seat, the tail frame is designed into a rectangular frame shape, one end of the tailstock is provided with a tailstock seat, the tailstock is horizontally arranged above the main frame, the main frame seat and the tailstock seat are hinged up and down oppositely, the upper oblique beam is hinged with a folding oil cylinder along the horizontal direction, the piston rod end of the folding oil cylinder points to the direction of the main frame seat, one end of the connecting rod is hinged with the tailstock base, the other end of the connecting rod is hinged with the piston rod end of the folding oil cylinder, one end of the swing rod is hinged with the main frame seat, and the other end of the swing rod is hinged with the connecting rod at the middle position.

As the utility model discloses a preferred scheme is located this folding hydro-cylinder rear, should go up and set up spacing seat on the sloping perpendicularly, and this tailstock level supports on this spacing seat.

After the technical scheme is adopted, the utility model provides a reverse folding spray lance frame of plant protection sprayer has beneficial effect is:

the utility model discloses a folding hydro-cylinder, a pendulum rod, a connecting rod constitute a link mechanism. When the piston rod of the folding oil cylinder extends out, the swing rod begins to swing forwards and pushes the connecting rod together with the piston rod of the folding oil cylinder, the tail frame rotates reversely along the hinged point of the main frame seat and the tail frame seat under the driving of the connecting rod and is unfolded, and the tail frame is unfolded reversely for 180 degrees to a horizontal working position. Otherwise, the piston rod of the folding oil cylinder is contracted, and the tail frame is reversely folded to the original non-working position, so that the transverse width is shortened, and the walking and transferring in the field are facilitated. The connecting rod mechanism is simple, does not occupy space, saves labor in the folding process and improves the reliability. Therefore, the effect of simple structure and high reliability is obtained.

Drawings

FIG. 1 is a schematic structural view of a reverse folding spray boom frame of the plant protection sprayer of the present invention;

FIG. 2 is an expanded view of FIG. 1;

fig. 3 is a partial enlarged view of i in fig. 2.

In the figure: a main frame 1; a main frame base 2; a tailstock 3; a tailstock base 4; a folding oil cylinder 5; an upper sloping beam 6; a swing link 7; a connecting rod 8; and a limiting seat 9.

Detailed Description

The invention will be described in further detail with reference to the following drawings and detailed description:

as shown in fig. 1, fig. 2 and fig. 3, the structure schematic diagram of the reverse folding spray rod rack of the plant protection spraying machine of the present invention is provided, which comprises a main rack 1, a main rack seat 2, a tail rack 3, a tail rack seat 4, a folding oil cylinder 5, an upper oblique beam 6, a swing rod 7 and a connecting rod 8, wherein the upper oblique beam 6 is arranged above the main rack 1, the upper oblique beam 6 and the horizontal beam of the main rack 1 form a triangular truss, the intersection end of the upper oblique beam 6 and the horizontal beam of the main rack 1 is provided with the main rack seat 2, the tail rack 3 is designed into a rectangular frame shape, one end of the tail rack 3 is provided with the tail rack seat 4, the tail rack 3 is horizontally arranged above the main rack 1, at this time, the main rack seat 2 and the tail rack seat 4 are hinged relatively up and down, the folding oil cylinder 5 is hinged on the upper oblique beam 6 along the horizontal direction, the piston rod end of the folding oil cylinder 5 points to the main rack seat 2, one end of the connecting rod 8 is hinged, the other end of the connecting rod 8 is hinged with the end of the piston rod of the folding oil cylinder 5, one end of the swing rod 7 is hinged with the main frame seat 2, and the other end of the swing rod 7 is hinged with the connecting rod 8 at the middle position.
