Agricultural spraying machine

Abstract

The invention relates to an agricultural spraying machine which comprises a frame, a hopper, a spraying mechanism, a power mechanism, wheels and a material quantification control device. The agricultural spraying machine is characterized in that the wheels are mounted on two sides of the frame, the hopper is supported on the upper side of the frame, the spraying mechanism is arranged below the hopper and is fixed onto the frame, and the frame is of a truss structure. The agricultural spraying machine has the advantages that the weight of a machine body can be reduced, damage to crops can be prevented, the spraying quantity can be accurately controlled, and the agricultural spraying machine is flexible in use.

Description

technical field [0001] The invention relates to the technical field of plant protection machinery, in particular to an agricultural spreading machine. Background technique [0002] Spraying plants is one of the economical and effective means of plant protection. The purpose is to eliminate diseases, insects, weeds and other harmful organisms before they are harmed and prevent them from causing disasters. Throwing machinery is currently being used more in plant protection. The current spreader still has the following defects: one is that the fuselage is welded with steel plates, which leads to its own weight, especially the overall comparison with the tractor. In addition, ordinary tires are used, the pressure is high, the appearance is hard, and there are deep grooves Patterns are more harmful to crops. In some places, in order to facilitate the operation of large and medium-sized sprayers, special tire passages need to be reserved in the field, resulting in waste of land r...

AI Technical Summary

Problems solved by technology

The current spreader still has the following defects: one is that the fuselage is welded with steel plates, which leads to its own weight, especially the overall cumbersome type matched with the tractor. In addition, ordinary tires are used, which have high pressure, hard appearance, and deep grooves Patterns are more harmful to crops. In some places, in order to facilitate the operation of large and medium-sized sprayers, special tire passages need to be reserved in the field, resulting in waste of land resources; Reasonable and wasteful; the third is that the flat-type spraying plate has insufficient spraying range; the fourth is that the power mechanism adopts a structure such as an integrated casting gearbox, which is not only heavy, but also inconvenient to connect with the tractor, and the connection structure cannot be flexibly adapted to on-site turning and other operations
