Strip-shaped composite planting high-ground-clearance zoning boom sprayer

Abstract

The invention relates to the technical field of agricultural mechanical equipment, in particular to a strip-shaped composite planting high-ground-clearance zoning boom sprayer. The sprayer comprises a rack, a parallel four-bar mechanism, a hydraulic lifting steering mechanism, a boom mechanism and an anti-interference mechanism are arranged at the front end of the rack, and a wheel track adjusting mechanism and a hydraulic steering mechanism are arranged below the rack. A variable spraying mechanism is arranged on the rack, operation is convenient, under the action of the anti-interference mechanism, when sprayers spray pesticide, an anti-interference plate can partition the sprayers, sprayed pesticide is prevented from interfering with one another, pesticide damage caused by mutual interference of different kinds of pesticide is avoided, the variable spraying mechanism can adjust the spraying pressure and the spraying flow according to the vehicle speed under the action of a speed sensor, the spraying distribution uniformity is improved, and spraying is uniform.

Description

Technical field: [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a belt-shaped compound planting high-gap zone-spray boom sprayer. Background technique: [0002] With the rapid development of rural revitalization, the traditional planting mode of small farmers is gradually replaced by planting cooperatives. The change of planting mode has promoted the progress and development of agricultural machinery and equipment. At present, in the field management link of agricultural production, weeding in the field is still Mainly chemical weeding, the existing chemical weeding equipment is rich in types, among which the high clearance self-propelled boom sprayer is recognized by the majority of growers for its advantages of high operating efficiency, easy operation, and uniform spray distribution. In production, the intercropping planting mode among crops has been promoted by experts on a large scale because it improves the...

[0002] With the rapid development of rural revitalization, the traditional planting mode of small farmers is gradually replaced by planting cooperatives. The change of planting mode has promoted the progress and development of agricultural machinery and equipment. At present, in the field management link of agricultural production, weeding in the field is still Mainly chemical weeding, the existing chemical weeding equipment is rich in types, among which the high clearance self-propelled boom sprayer is recognized by the majority of growers for its advantages of high operating efficiency, easy operation, and uniform spray distribution. In production, the intercropping planting mode among crops has been promoted by experts on a large scale because it improves the utilization rate of land resources, makes full use of the nutrient complementarity among crops and suppresses diseases and insect pests. However, the chemical herbicides of different crops are quite different, and even mutually exclusive. The interference is serious, resulting in phytotoxicity, resulting in a substantial reduction in crop yields, and although the use of high-gap self-propelled boom sprayers can chemically weed better, reduce the use of pesticides, improve the utilization of pesticides, and reduce the damage, but the high-gap self-propelled Whether the spray sprayed by the walking boom sprayer is uniform is affected by the operator. When the sprayer moves fast, the relative amount of spraying is small, which will lead to incomplete removal of weeds, and the walking speed of the sprayer is slow. If the amount is too large, it will cause phytotoxicity and affect crops
