Problems solved by technology

The nozzle of the original sprayer is only placed on the top of the cotton plant and there is no air-conveying system. It is easy to cause the liquid mist to adhere unevenly on the top and bottom of the cotton plant, and the leaves and bolls are not neatly opened. In addition, it is easy to cause the waste of medicinal liquid, the residual amount of medicinal liquid after harvesting is high, and the quality of cotton is reduced.

Embodiment 1

[0026] The power of the tractor is driven by the belt between the output pulley and the input pulley of the commutator, and reaches the commutator (1). Part of the power is transmitted to the diaphragm pump (2) through the belt drive between the pulley on the shaft and the diaphragm pump pulley, driving the diaphragm pump (2) to rotate at high speed to provide the required power for the spray system. Another part of the power output by the output shaft at the rear end of the commutator is transmitted to the centrifugal fan pulley Ⅰ (6) through the transmission shaft (5), and the power passes between the centrifugal fan pulley Ⅰ (6) and the centrifugal fan pulley Ⅱ (7). The belt transmission is transmitted to the centrifugal fan (8), which drives the centrifugal fan (8) to rotate at high speed to provide the required power for the air delivery system.

[0027]Under the action of the high-speed rotating diaphragm pump, the liquid medicine flows out from the liquid medicine tank ...

Embodiment 2

[0031] The present invention needs to be used in conjunction with a high clearance tractor suitable for cotton plant protection operations in the late stage, and the power transmission device, liquid medicine spray system, air delivery system, and hydraulic lifting mechanism are reasonably arranged and installed on the tractor. In this example, three boom profiling mechanisms are provided to tightly enclose the front shield (19) and the rear shield (22) on the front and rear sides of the perforated air duct (17) (with the forward direction of the tractor as the front). Clamp (20) fixes the three, wherein the clamp of the porous air duct is installed between the front and rear shields, and the air outlet is towards both sides. Connect the front shield to the boom connecting frame (14) with connecting square steel (21), and the boom connecting frame (14) is closely connected with the lifting connecting frame (13). A vertical drug rod (18) is respectively installed on both sides ...

Abstract

The invention relates to a pneumatic conveying type suspender profiling ripener spraying machine for cotton fields. The spraying machine is composed of a power drive device, a pesticide liquid spraying system, a pneumatic conveying system, a hydraulic lifting mechanism and a suspender profiling device. Wind outlets and a vertical pesticide rod are arranged on a multi-hole wind duct, jet stream fields are formed in the regions of the two sides of the wind duct, and then spraying fog drops are secondarily atomized, and the pesticide liquid adhesive rate is increased. The hydraulic lifting mechanism and the suspender rod profiling device are arranged, and then the suspender profiling device can meet operating requirements at different heights. Ripener can be evenly sprayed to the upper, the middle and the lower positions of cotton plants, the high defoliation rate and the high boll opening rate are achieved, and the spraying machine can be suitable for land parcels of different shapes and the cotton fields of different growth vigor.

Description

(1) Technical field [0001] The invention relates to a cotton field air-supplied boom profiling ripening agent sprayer. (2) Background technology [0002] my country is a big cotton growing and producing country, with a planting area of ​​more than 80 million mu and an output of more than 7 million tons. At present, although the domestic cotton mechanized harvesting technology is in its infancy, its development is like a broken bamboo. It is imperative to realize cotton mechanized harvesting in China, and cotton defoliation is currently a key link that restricts the promotion of mechanized cotton picking technology. The development and popularization of cotton mechanical harvesting technology has become a bottleneck problem in improving domestic cotton production efficiency. It is very important to develop a sprayer specially used for spraying liquid medicine that has high operating efficiency, uniform spraying of liquid medicine, high defoliation rate and boll opening rate,...
