Design method for postpositional pesticide spraying machine matched with corn straw returning machine

Abstract

The invention relates to a design method for a postpositional pesticide spraying machine matched with a corn straw returning machine. The postpositional spraying machine includes the followings parts: 1) a pesticide storage box, wherein the length, the width, and the height of the pesticide storage box are 300 cm, 150 cm and 120 cm respectively, and the volume of the pesticide storage box is 500 L; 2) a diaphragm pump, wherein the displacement is 80 L / min, the revolving speed is 550 rpm, and the working pressure is 0.3 MPa, the working power is 24 V, and the diaphragm pump is directly connected to an operation panel in a cab; 3) a spraying rod, wherein the length of the spraying rod is 350 cm, six number 5 nozzles are evenly distributed on the spraying rod, and the spraying width of the spraying rod is 80 cm; and 4) the pesticide storage box and the diaphragm pump as well as the diaphragm pump and the spraying rod are connected through high pressure soft rubber pipes.

Description

technical field [0001] The invention belongs to the technical field of use of corn stalk processing machinery, and in particular relates to a method for designing a rear spraying machine matched with corn stalk returning to the field. Background technique [0002] Corn stalks are the product of plant photosynthesis and are a valuable biological resource. Due to poor utilization, a large number of stalks can be seen being burned during the harvest season in summer and autumn. The billowing smoke brings not only a waste of resources , and become the chief culprit of environmental pollution. my country is a large agricultural country. In 2012, the output of straw reached more than 700 million tons, and its nutrients were equivalent to more than 3 million tons of nitrogen fertilizer, more than 7 million tons of potassium fertilizer, and more than 700,000 tons of phosphorus fertilizer. It is a very huge treasure house of plant nutrients. According to statistics, the amount of st...

Problems solved by technology

However, the domestic situation is not optimistic. Due to agronomic technology and agricultural machinery and other reasons, straw treatment has many obstacles and the effect is poor. The current season wheat shows low seedling emergence rate, yellow seedlings, weak seedlings, and even dead seedlings, not only does not increase production. , but the phenomenon of reduced production
