A micro-spray belt rapid rolling device and method suitable for field water and fertilizer integration

Abstract

The invention relates to a quick unwinding and winding device and a method of a micro-sprinkling belt suitable for the field integration of water and fertilizer. The quick unwinding and winding device comprises a rack, a screw shaft, a sleeve shaft, a belt winding wheel disc, a swing mechanism, a guide mechanism and a transmission mechanism, wherein the screw shaft is installed in a top hole of the rack by virtue of a bearing, and the end surface of the bearing of the screw shaft is overlapped with the front surface of the rack; one end with a pin shaft hole passes through the top hole of the rack and extends out for a certain distance; the sleeve shaft is installed in the top hole of the rack by virtue of another bearing; the swing mechanism comprises a fixed shaft, a swing rod, a camshaft and a cam; the belt winding wheel disc comprises an inner rotary disc, a support shaft, an outer rotary disc and a pressing rotary disc; the guide mechanism comprises a roller shaft, a roller bracket and a roller; the transmission mechanism comprises a motor, a motor base, a fixed pulley shaft, a fixed pulley, a movable pulley, a wire pulling ring, a rope, a large chain wheel, a small chain wheel, a swing chain wheel and a chain. According to the quick unwinding and winding device and the method, the unwinding quality of the micro-sprinkling belt is obviously increased, and the problem of uneven sprinkling of the belt due to uneven unwinding of the micro-sprinkling belt is greatly solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a micro-spray tape rapid roll-up device and method suitable for field water and fertilizer integration, and is especially suitable for use in micro-spray tape water-saving irrigation of field crops such as wheat, corn, and cotton. [0002] technical background [0003] Micro-spray belt is a new type of micro-irrigation equipment, also known as "porous hose". The working principle is to send water to the field through the water pipe and the micro-spray belt under pressure, and form a drizzle-like spraying effect under the action of gravity and air resistance through the water outlet holes on the micro-spray belt. Compared with sprinkler irrigation, there will be no phenomena such as soil compaction, field runoff, water and soil loss, and reduced fertilizer efficiency; compared with drip irrigation, micro-spray belts are more resistant to clogging; compared with drip ir...

Problems solved by technology

However, most of the micro-spray tape rolls used in Daejeon are manually operated, which is very time-consuming, labor-intensive, and labor-intensive, and the labor and production efficiency is low.

Manual rolling of the micro-spray belt will cause the micro-spray belt to turn over, resulting in unevenness of the micro-spray belt, reducing the uniformity of irrigation water distribution, affecting water-saving irrigation, and even leading to crop yield reduction

[0005] After searching the existing technical literature, it was found that the Chinese utility model patent "a single-arm micro-spray tape retractor", application number 2014420336575.6, provides a device for rolling up the micro-spray tape, which fixes the micro-spray tape on a simple The bracket can realize the retraction of the micro-spray tape by turning the handle, but it still cannot realize the laying of the micro-spray tape. Such an operation still requires manual intervention, low production efficiency, and a waste of labor. wear and tear

[0006] Therefore, in view of the time-consuming and labor-intensive laying of the micro-spray tape, which affects the implementation efficiency of water and fertilizer integration, it is urgent to invent a device and method for the rapid laying and rewinding of the micro-spray tape that is suitable for field water and fertilizer integration operations. Work efficiency and increasing food production have important practical significance
