Abstract
The utility model discloses a spray arm folding device of a spray boom type drug sprayer, which comprises an unfolding and folding device arranged between a left spray arm and a right spray arm. The unfolding and folding device comprises a grooved frame fixed on a spray arm support frame, the two ends of the grooved frame are respectively hinged with the left spray arm and the right spray arm, the outer bottom wall of the grooved frame is fixedly provided with a tension spring bracket, the tension spring is arranged between two hinge shafts, the inner sides of the left spray arm and the right spray arm are fixedly provided with a tension spring support block, and a tension spring is respectively arranged between the tension spring bracket and the tension spring support blocks. The utility model has the advantages of simple structure and convenient operation. The left spray arm and the right spray arm can be rapidly folded through the unfolding and folding device after drug spraying, thereby greatly reducing space occupied by the drug sprayer.
Description
Technical field
The utility model relates to a kind of spray boom formula Insecticide sprayer spray arm collecting device.
Background technology
Spray boom formula Insecticide sprayer has been applied in the spraying laxative, but is applicable to that the spray boom formula Insecticide sprayer that uses in the chipping area territory also seldom.Spray boom formula Insecticide sprayer comprises handrail, holder part, armrest portion, left spray arm, right spray arm and front-wheel governor motion etc.Holder part comprises two wheels, spray arm bracing frame and handrail installing rack.Left and right spray arm is installed in respectively on the spray arm bracing frame of holder part, and the length of spray arm has determined the fabric width length of laxative.Require spray arm that certain length is arranged during use, after spray arm trails, can cover big zone to realize the operation of large-area spray medicine.After laxative finished, the expansion of spray arm can be given to deposit and be brought a lot of inconvenience, because of it takes up room greatlyyer, therefore spray arm need be drawn in to reduce floor space.
The utility model content
The purpose of this utility model provides a kind of spray boom formula Insecticide sprayer spray arm collecting device, and this device can draw the spray arm of spray boom formula Insecticide sprayer quickly and easily in, it is taken up room reduce, deposit conveniently.
To achieve these goals, the utility model is by the following technical solutions:
A kind of spray boom formula Insecticide sprayer spray arm collecting device, it comprises: one is arranged on the expansion collecting device between the left and right spray arm.
Described expansion collecting device comprises the grooved frame that is fixed on the spray arm bracing frame, hinged left and right spray arm respectively in the groove at the both ends of grooved frame, on the diapire of this grooved frame, set firmly the extension spring support, this extension spring support is between two jointed shafts, set firmly an extension spring bearing respectively in the inboard of left and right spray arm, between extension spring support and each extension spring bearing, an extension spring is set respectively.
Described extension spring support is positioned in the middle of two jointed shafts of left and right spray arm and grooved frame, and described extension spring bearing is installed in the left and right spray arm medial end of contiguous jointed shaft.
The beneficial effects of the utility model: the resulting a kind of spray boom formula Insecticide sprayer spray arm collecting device of the utility model, it is simple in structure, easy to operate, after finishing, laxative left and right sides spray arm is drawn in fast by expansion collecting device of the present utility model, significantly reduced taking up room of Insecticide sprayer.
Description of drawings
Fig. 1 is the structural representation (left spray arm is that deployed condition, right spray arm are rounding state) of a kind of spray boom formula of the utility model Insecticide sprayer spray arm collecting device.
The specific embodiment
As shown in Figure 1, a kind of spray boom formula Insecticide sprayer spray arm collecting device, it comprises: one is arranged on the expansion collecting device between the left and right spray arm 2,3.
Launch collecting device and comprise the grooved frame 5 that is fixed on the spray arm bracing frame 9, hinged left and right spray arm 2,3 respectively in the groove at the both ends of grooved frame 5, the cross section of grooved frame 5 is spill or takes the shape of the letter U, or grooved frame 5 is a channel-section steel.Set firmly extension spring support 7 on the diapire of this grooved frame 5, the upper end of extension spring support 7 is higher than the upper side wall of grooved frame 5, and extension spring support 7 sets firmly an extension spring bearing 8 respectively in the inboard of left and right spray arm 2,3 between two jointed shafts 4.This inboard is a left and right spray arm when drawing in, the direction of its rotation.The top of this extension spring bearing 8 is roughly concordant with the top of extension spring support 7, and hook is established an extension spring 6 respectively between the upper end of the upper end of extension spring support 7 and each extension spring bearing 8.
Extension spring support 7 is positioned at the middle part of two jointed shafts 4 of left and right spray arm 2,3 and grooved frame 5, and extension spring bearing 8 is installed in the medial end of the left and right spray arm 2,3 of contiguous jointed shaft 4.
Left spray arm 2 is launched state as shown in the figure, and spring was in tensioning state and made left spray arm be subjected to power toward A and B direction this moment.B to power left spray arm is fixed near the inboard of grooved frame, by B to power make left spray arm be close to grooved frame inboard, be lock-out state.Right spray arm is a rounding state, when right spray arm 3 is point of rotation rotation with jointed shaft 4, when the spring 6 right spray arm 3 corresponding with it is positioned at same straight line, spring forms the dead point, this spray arm spend the dead point will be subjected to D to C to power right spray arm is drawn close to handrail 1, finally be fixed in the spray arm limiting plate 11 on the handrail 1.This moment right spray arm be subjected to D to C to power, D inwardly draws right spray arm in to stressed.When left side spray arm 2 and right spray arm 3 two states, because the effect of spring tension makes spray arm the situation of rocking along bolt can not occur.And when spray arm rotate to when spending the spring dead point spray arm can effect at spring tension under in-position automatically.
This device can draw the spray arm structure of launching spray boom formula Insecticide sprayer quickly and easily in.Spray boom is installed in the grooved frame, is contained in extension spring one end that the other end is contained on the spray arm on the grooved frame, is provided with by the dead point to make spray boom spring when launching and draw in all be in tensioning state.
More than be preferred embodiment of the present utility model and design graphic; above-mentioned preferred embodiment and designing graphicly only illustrates; be not to be used to limit interest field of the present utility model; all with equalization technological means or be the interest field that contained of the application's claim and the implementer does not all break away from protection domain of the present utility model.
