Abstract
The utility model provides a wheel tread adjustable crop spraying machine in order to solve the problem that the conventional three-wheel crop spraying machine easily runs over plants. The spraying machine comprises a three-wheel tractor, wherein a rear axle of the three-wheel tractor consists of three sections, namely a left section and a right section which are fixed shafts, and a middle section which is a variable shaft; one ends of the fixed shafts are fixed with wheels, and the other ends of the fixed shafts are provided with external threads; two ends of the variable shaft are respectively provided with internal threads which are matched with the external threads on the fixed shafts; operating pieces for rotating are arranged on the surfaces of the fixed shafts or the variable shaft; and an oil filling port is formed on a shell where the internal threads of the fixed shafts are positioned. The middle variable shaft is a shaft having different effective lengths and can be replaced according to the row spacing; and therefore, the wheel base of the rear axle is changed. By the crop spraying machine, the wheel base of the rear axle can be adjusted to adapt to the planting row spacing of different crops.
Description
Technical field
The utility model relates to the sprayer unit that makes in a kind of agricultural plant protection, particularly a kind of three-wheel crops sprayer.
Background technology
Three-wheel crops sprayer is by three-wheel tractor and be fixed on sprayer unit on the three-wheel tractor etc. and form, and the rear tread of existing three-wheel crops sprayer is fixed.But different crops needs different line-spacings because habit of growth is different during plantation; Line-spacing like wheat is about 16cm, and the line-spacing of castor-oil plant is 100-120cm, and the line-spacing of corn is 40-60cm; Efficient plantation of cover and wide-narrow row planting between the development solid, line space changes also greatly.The fixing sprayer of existing wheelspan as adopting overwhelms plant easily in operating process.
Summary of the invention
The utility model provides a kind of wheelspan adjustable crops sprayer in order to solve the problem that existing three-wheel crops sprayer damages plant easily by pressure.
The technical scheme that the utility model adopts is: the crops sprayer that a kind of wheelspan is adjustable; Comprise three-wheel tractor, the hind axle of three-wheel tractor is formed by three sections, and left side section is a fixed axis with right section; Interlude is a flexible shaft; One end and the wheel of fixed axis are fixed, and the other end is provided with internal thread, the flexible shaft two ends be respectively equipped with fixed axis on the external screw thread of screw-internal thread fit.
Middle flexible shaft is the axle with different length effective length, can change according to line-spacing, thereby change the wheelbase of hind axle.
The crops sprayer that the described wheelspan of the utility model is adjustable, hind axle be apart from can regulating, can adapt to different crops the plantation line-spacing.
