Automatic guide type spray irrigating machine and spray irrigating method for greenhouse

Abstract

The invention discloses an automatic guide type spray irrigating machine and a spray irrigating method for a greenhouse. The spray irrigating machine comprises a differential steering chassis, a micro control system, a water supply system and a storage battery, wherein the differential steering chassis includes a vehicle frame, a left driving system, a right driving system and omnidirectional wheels, power is supplied to the left driving system and the right driving system through the storage battery to drive the spray irrigating machine to travel. As the differential steering chassis is employed, the spray irrigating machine can travel and steer automatically along with a guide line under the control of the micro control system, without needing manual removal or special rail-based transfer; and during the travelling, water in a water tank is pumped by a water pump and is sprayed through a nozzle to realize spray irrigation; a master controller is configured to calculate amount of deviation of the spray irrigating machine from the guide line during the travelling process and give a control command to control revolving speeds of a left electric motor and a right electric motor, so as to enable the spray irrigating machine to travel along the guide line all the time. The spray irrigating machine disclosed by the invention has the advantages that the labor intensity is reduced, the cost for greenhouse construction and spray irrigating machine investment is lowered, the running distance of a single spray irrigating machine is not limited, the spray irrigating area for the greenhouse is large, the structure is simple, the automation degree is high and the practicality is strong.

Description

technical field [0001] The invention relates to the field of water-saving and energy-saving irrigation in farmland, in particular to a greenhouse automatic guided sprinkler irrigation machine and a sprinkler irrigation method suitable for walking on the ground in a greenhouse. Background technique [0002] With the large-scale construction of large-scale modern multi-span greenhouses, the development of greenhouse sprinkler irrigation machinery has received more and more attention. The greenhouse suspension sprinkler irrigation machines currently used are installed on the upper end of the greenhouse. Undertaken on the moving track, the main engine is driven by the motor to move, and the main engine drives the spray boom to move forward while driving, and drags the cables and water delivery hoses hanging on the carrying pulley to move forward along the slide rail, while the external water pump supplies water, pressurized water Finally, it is sprayed through spray bars and noz...

AI Technical Summary

Problems solved by technology

However, in the actual application process, because of the need to install a special suspension track for the movement of the sprinkler, this requires high structural strength requirements for the greenhouse, resulting in complex design of the supporting steel frame and truss structure of the greenhouse, and high infrastructure investment.

At the same time, the transfer of the sprinkler from the greenhouse building to the building requires a special transfer device and a transfer track. The design of the structure is complex, and the transfer of the sprinkler is inconvenient, which makes the sprinkler low in efficiency, reliability, and automation. It is difficult to apply on a large scale. modern greenhouse irrigation
