Special spraying device suitable for sorghum planting

Abstract

The invention relates to the field of sorghum planting, in particular to a special spraying device suitable for sorghum planting. The device comprises a vertically arranged support mounting cylinder,a water inlet pipe is arranged at the right upper end of the support mounting cylinder, a plurality of support mounting plates are horizontally arranged at the upper end of the support mounting cylinder at equal angles, and fixed mounting holes are formed in the support mounting plates. A driving flow guide cylinder is vertically arranged in the middle of the lower end of the support mounting cylinder, a transmission mounting cover is vertically arranged at the lower end of the driving flow guide cylinder, and a rotating flow guide cylinder is vertically arranged in the middle of the transmission mounting cover; through pressurized flow guide, accompanying with a uniform pesticide adding structure, pesticide liquid of the device can be mixed evenly, spraying pesticide liquid can be generated immediately, continuous rotation of the device is achieved through gear and gear ring transmission, the spraying uniformity and range of the device are remarkably improved, the distance and angle between the device and sorghum are controlled through uniform flow guide and in cooperation with swing and telescopic adjustment, and the adaptive adjustment capacity of the device is remarkably improved.

Description

Technical field[0001]The invention relates to the field of sorghum planting, in particular to a special spraying device suitable for sorghum planting.Background technique[0002]Sorghum is an annual herbaceous plant in the Gramineae family. The culm is thick and upright, with supporting roots on the base nodes. The leaf sheath is glabrous or slightly powdery; the leaf tongue is dura mater, rounded at the apex, and ciliated at the edge. The panicles are loose, the main axis is exposed, and the total peduncle is erect or slightly curved; 3 stamens, anthers about 3 mm; ovary obovate; styles separated, stigmas are scrambled. The caryopsis are flat convex on both sides, light red to reddish brown, 2.5-3 mm wide when ripe, and slightly exposed at the top. The stalk of the stalked spikelet is about 2.5 mm long, the spikelet is linear to lanceolate, and the flowering and fruit period is from June to September. Sorghum likes temperature and light, and has certain high temperature resistance ch...

AI Technical Summary

Problems solved by technology

[0003] The use of pesticide spraying in the prior art has a very important effect on the growth of crops. It can make the growth of sorghum more high-quality, prevent insect damage, and improve the disease resistance of crops. However, the existing spraying devices rely on manual spraying. The operation is labor-intensive, and the height is not enough to completely cover the sorghum, the efficiency is low, and the two rows of sorghum cannot be sprayed at the same time, which greatly reduces the use efficiency of the device, so it cannot meet the needs of the existing technology

[0004] Chinese patent (notification number CN210630491U) discloses a spraying device for sorghum planting. Although it can be improved for the above problems, there are deficiencies in the design of the dosing structure and the adaptability adjustment, resulting in unsatisfactory spraying effect.
