Description
Technical field
The utility model belongs to agricultural vehicle technology field, specifically, and the particularly top cover closing device on agricultural unmanned vehicle.
Background technology
Along with social development, the progress of science and technology, the work such as spray insecticide on a large scale in farmland, fertilising are progressively completed by unmanned vehicle.Top cover is the vitals on agricultural unmanned vehicle, plays closed fuselage upper port.Existing top cover is convertible structure, and locks by lockset.In use, top cover not only weight greatly, easily damage; And very inconvenience of folding, not only complex operation, and waste time and energy, the convenience that very impact is used.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of agricultural unmanned vehicle top cover closing device of folding with convenience.
The technical solution of the utility model is as follows: a kind of agricultural unmanned vehicle top cover closing device, be provided with the top cover (1) adapting with it at the opening part at fuselage (7) top, be fixed with a fixture block (2) and two positioning seats (3) at described top cover (1) the bottom surface place of keeping to the side, described fixture block (2) is connected to the open-topped edge of fuselage (7), and fixture block (2) and two positioning seats (3) are uniformly distributed at circumferencial direction, interior outer end in each positioning seat (3) bottom is respectively arranged with interior journal stirrup (3a) and outer journal stirrup (3b), in same positioning seat (3), on outer journal stirrup, jointly wear latch (4), the outer end of this latch (4) exceeds the outer of top cover (1), and the inwall of the outer end of latch (4) and fuselage (7) top ports connects, at the upper vertical fixing driving lever (5) of described latch (4), the upper end of this driving lever (5) is through positioning seat (3) and the corresponding bar shaped via hole arranging of top cover (1), on described latch (4), be set with spring (6), one end of this spring (6) and interior journal stirrup (3a) connect, the other end of spring (6) and driving lever (5) connect.
The utility model is in closing top cover, first the gap between crosspiece under fixture block and top cover is snapped in to the edge of fuselage top end opening, top cover is carried out on fuselage to Primary Location, then stir two driving levers simultaneously, make the direction motion of two driving levers to top cover center, now spring is compressed, when driving lever motion, together with the latch that drive is fixedly connected with driving lever, move, make in the retraction top cover edge, outer end of latch, like this top cover completely spiral-lock at the opening part on fuselage top, and fuselage top end opening is sealed, finally unclamp driving lever, under the effect of recoil of spring power, driving lever and latch reset, the inwall of the outer end of latch and fuselage top end opening pushes against, under the combined action of two latches and a fixture block, top cover tightly spiral-lock at fuselage top, can not occur loosening or come off.In the time that top cover need to be opened, only need stir driving lever according to above operating mode, make latch retract, then around upwards flip top cover of fixture block.
Described fuselage (7) is made up of carbon fiber composite material, and fuselage is lightweight like this, and structural strength is good, can not deform or damage, and long service life.
Described fixture block (2) is " Z " shape, and the bottom surface of the upper crosspiece of fixture block (2) and top cover (1) fits, and fixes by bonding or screw, between the lower crosspiece of fixture block (2) and the bottom surface of top cover (1), forms bayonet socket, this bayonet socket and fuselage (7) phase clamping.Above structure on the one hand between fixture block and top cover area of contact large, connect not only firmly but also reliable; On the other hand, the bayonet socket under fixture block between crosspiece and top cover bottom surface can conveniently be located, and is conducive to top cover and fuselage clamping is firm.
For the end face of positioning seat is firmly connected with the bottom surface of top cover, the end face of described positioning seat (3) fits fixing by bottom surface bonding or screw and top cover (1).
For simplified structure, facilitate processing and fabricating, prevent that latch from coming off, the inner of described latch (4) is bulb, this bulb is spacing by interior journal stirrup (3a).
Beneficial effect: the utility model is by arranging a fixture block and two telescopic latches at the edge of top cover bottom surface, and closely cooperate by mode and the fuselage of clamping and butt respectively, folding top cover quickly and easily, features such as thering is modern design, simple in structure, processing ease, be easy to transformation, improvement cost is low.
