Efficient spraying machine suitable for cotton fields

Abstract

The invention provides an efficient spraying machine suitable for cotton fields and relates to farm machinery. The efficient spraying machine comprises a bracket, a draught fan, a draught fan power system, a pesticide box and a pesticide pump, wherein the draught fan, the pesticide box and the draught fan power system are respectively and fixedly arranged on the bracket; the outlet of the pesticide box is connected with the inlet end of the pesticide pump through a pipeline; the draught fan power system is in drive connection with the draught fan through a belt wheel rotation mechanism; the bracket is provided with a nozzle mounting bracket; the nozzle mounting bracket is provided with a plurality of row dividing devices, straight spraying barrels and inclined spraying barrels; air outlets of the direct spraying barrels and the inclined spraying barrels are provided with medicine feeding nozzles; wind screens are arranged between the draught fan and the straight spraying barrels and between the draught fan and the inclined spraying barrels; air inlets of the wind screens are connected with an air outlet of the draught fan; air outlets of the wind screens are respectively connected with the straight spraying barrels and the inclined spraying barrels. The spraying machine can uniformly apply pesticides and has strong penetrating power; the pesticide utilization amount per unit area is little.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a high-efficiency sprayer suitable for spraying pesticides in cotton fields. Background technique [0002] For the application of cotton fields, pure pressure atomizing sprayers are used in China to apply pesticides. In order to achieve fully automatic mechanization in cotton field production, defoliants need to be applied before cotton harvesting. Due to the high price of defoliants, the dosage needs to be strictly controlled. , the dosage of 30~35KG per mu of cotton field is controlled as needed, while the existing pure pressure atomization spraying is difficult to achieve the control of dosage; now the diluted medicinal solution is used to control the dosage of pesticide per mu, after dilution High-quality defoliants seriously affect the defoliation effect, and the final defoliation is not clean, resulting in more impurities in cotton after harvesting. Large-scale cotton fields lose ...
