Large-scale spraying machine
Technical field
The utility model relates to a kind of spraying machine, particularly a kind of large-scale spraying machine.
Background technology
Popularization along with mechanization of agriculture, the particularly utilization of high-power locomotive, the spraying operation of large-area farmland chemical control relies on the spraying machine of locomotive traction to finish more and more, in order to adapt with the high-power locomotive, spraying machine need carry enough medicaments, supporting spray boom, frame facility in addition, its live load weight is very big, and generally this class spraying machine generally all adopts towed.
Though but towed structure live load is big, the side underaction that seems when empty lotus is advanced.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of needs that can either adapt in the operation big load operation, again can be when empty lotus be advanced spraying machine, particularly a kind of large-scale spraying machine comparatively flexibly.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise frame (7), hanger bracket (5), medicinal cupping (4), spray frame (3) and transmission mechanism (6), it is characterized in that: be provided with road wheel (10), and described road wheel (10) is arranged on the elevating mechanism, this elevating mechanism comprises the slide block (9) in chute (8) and the chute (8), be provided with governor motion between chute (8) and the slide block (9), make and form a telescoping mechanism between chute (8) and the slide block (9), described road wheel (10) is connected on the slide block (9), and chute (8) then is connected with frame (7).
As improvement, above-mentioned chute (8) preferably is connected by crossbeam (13) with frame (7), and described crossbeam (13) is preferably the telescopic structure of adjustable in length.
Governor motion between above-mentioned chute (8) and the slide block (9) can be regulated for bolt, namely is provided with regulating tank (11) at chute (8) or slide block (9), by the fixing relative position between chute (8) and the slide block (9) of bolt (12); Also can regulate for hydraulic mechanism or screw mechanism, namely arrange between chute (8) and the slide block (9) that a hydraulic mechanism or screw mechanism are regulated or the fixing relative position between chute (8) and the slide block (9).
Can also for bolt adjusting and hydraulic mechanism or the combined mode of screw mechanism be regulated or the fixing relative position between chute (8) and the slide block (9), namely by the relative position between hydraulic mechanism (14) or screw mechanism adjusting chute (8) and the slide block (9), fix by bolt (12).
Compared with prior art, the utility model under the big situation of live load weight with the road wheel work that lands, to alleviate the pressure of hanger bracket in the work, then can complete machine be raised up by hanger bracket when light load or headland turn, improving flexibility, road advance or special occasions in then road wheel can be regained.

The specific embodiment
Embodiment 1:With reference to accompanying drawing 1~2, structural representation for the utility model embodiment 1, comprise frame 7, hanger bracket 5, medicinal cupping 4, spray frame 3 and transmission mechanism 6, be provided with road wheel 10 in frame 7, and described road wheel 10 is arranged on the elevating mechanism, this elevating mechanism comprises the slide block 9 in chute 8 and the chute 8, be provided with governor motion between chute 8 and the slide block 9, in the present embodiment, governor motion is that bolt is regulated, namely be provided with regulating tank 11 at chute 8 or slide block 9, by the fixing relative position between chute 8 and the slide block 9 of bolt 12, described road wheel 10 is connected on the slide block 9,8 of chutes pass through crossbeam 13 and are connected with frame 7, crossbeam 13 is the telescopic structure of adjustable in length, regulates the length of crossbeam 13, can adapt to the line-spacing of Different Crop.
Embodiment 2:With reference to accompanying drawing 3, structural representation for the utility model embodiment 2, compare with embodiment 1, the difference of present embodiment is: the governor motion between described chute 8 and the slide block 9 is hydraulic mechanism, namely at the relative position that arranges between chute 8 and the slide block 9 between hydraulic mechanism adjusting chute 8 and the slide block 9.
Above-mentioned hydraulic mechanism also can be replaced mutually by adjustable diameter and screw adjusting mechanism.
Embodiment 3:Compare with 2 with embodiment 1, the difference of present embodiment is: the governor motion between described chute 8 and the slide block 9 is that bolt is regulated with hydraulic mechanism combined, by the relative position that hydraulic mechanism 14 is regulated between chute 8 and the slide block 9, fix by bolt 12.
