A kind of powerful wind sent remote spraying equipment

Abstract

The invention relates to strong-air-assisted remote pesticide spraying equipment and belongs to the technical field of agricultural machinery. The equipment comprises a liquid pesticide box supported on a rack provided with traction wheels, wherein a transmission shaft powered by a traction machine is arranged at one end of the rack, and a centrifugal fan with an impeller shaft hinged to the rack is arranged at the other end of the rack; a guide air duct is mounted at an air outlet of a volute of the fan, an angle-adjustable air guide cover is mounted at the upper part of an outlet of the guide air duct, and spraying parts are mounted on the upper side and the lower side of the outer end of the air guide cover respectively; the liquid pesticide box is connected with the spraying parts through pump pressurization pipelines, and the transmission shaft is in transmission connection with the fan impeller through a coupler; an indexable hydraulic cylinder is hinged to the rack at the fan, and the outer end of a piston rod of the hydraulic cylinder is hinged to the volute of the fan. Droplets can be distributed remotely and effectively cover targeted crops in a sedimentation area, besides, the droplets have ideal penetrability, agricultural non-point source pollution is reduced, and quality safety of agricultural products is guaranteed.

Description

technical field [0001] The invention relates to crop pesticide application equipment, in particular to a powerful air-driven remote pesticide application equipment for high-stalk crops, belonging to the technical field of agricultural and forestry plant protection. Background technique [0002] According to the applicant's knowledge, for a long time, the pest control operations of high-stalk crops such as corn and sugarcane have mainly relied on knapsack-type manual (electric) sprayers, knapsack-type power spray dusters and other small machines, while rapeseed, cotton and other crops are cross-sealed in the late growth period. However, traditional spraying equipment cannot enter the field for spraying operations. Once such crops encounter explosive pests and diseases, it is often difficult to effectively control them, resulting in a large reduction in crop production, or even failure.

[0002] According to the applicant's knowledge, for a long time, the pest control operations of high-stalk crops such as corn and sugarcane have mainly relied on knapsack-type manual (electric) sprayers, knapsack-type power spray dusters and other small machines, while rapeseed, cotton and other crops are cross-sealed in the late growth period. However, traditional spraying machines cannot enter the field for spraying operations. Once such crops encounter explosive pests and diseases, it is often difficult to effectively control them, resulting in a large reduction in crop production, or even failure

[0003] In recent years, the high-stalk (elevated) boom sprayer developed to meet the needs of high-stalk crops for pest control can walk between rows of tall-stalk crops such as corn and perform spraying operations. It is difficult for the droplets of the liquid medicine to reach the middle and lower parts of the plant and the back of the leaves, so satisfactory control effects cannot be obtained, and it is easy to cause environmental pollution.
