Self-propelled sprinkler irrigation machine and sprinkler irrigation method for greenhouse

Abstract

The invention discloses a greenhouse self-propelled sprinkler and a sprinkling method. The sprinkler comprises a main unit, a telescopic and foldable truss type sprayer and a cable and water conveying hose bearing device. The main unit comprises a vehicle frame, a front universal wheel, a rear drive wheel, a first drive motor and a speed reducer. The telescopic and foldable truss type sprayer comprises a second drive motor, a lead screw and a telescopic and foldable truss mechanism. The cable and water conveying hose bearing device comprises a sliding rail, bearing tackles and bearing hooks. The first drive motor drives the main unit to move forwards or retreat, and the main unit drags a cable and a water conveying hose hung on the bearing tackle to move forwards along the sliding rail while moving forwards. The telescopic and foldable truss type sprayer can be unfolded when carrying out sprinkling, so that the one-time sprinkling control area is large, the sprinkling uniformity is high, and the greenhouse area occupied by the sprinkler is reduced. Meanwhile, the front universal wheel and a ground rail control the sprinkler to transfer, so that the problems that a greenhouse structure is complex and the manufacturing cost is high when a greenhouse hanging type sprinkler is used are solved well. The greenhouse self-propelled sprinkler is simple and compact in structure and high in reliability.

Description

technical field [0001] The invention relates to the field of water-saving and energy-saving irrigation in farmland, in particular to a greenhouse self-propelled sprinkler irrigation machine and a sprinkler irrigation method suitable for walking on the ground of the greenhouse. Background technique [0002] With the large-scale construction of large-scale multi-span greenhouses, more and more attention has been paid to greenhouse sprinkler irrigation machines. The currently used greenhouse sprinkler irrigation machines are installed on the upper end of the greenhouse to move and transfer suspension rails for the main engine. The driving wheels of the main engine are carried on the moving rails. The main engine is driven by the motor, and the main engine drives the spray boom to move forward while the main engine walks, and drags the cables and water hoses hanging on the load-carrying trolley to move forward along the slide rail. At the same time, the external water pump suppli...

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 makes the structural strength of the greenhouse very high, resulting in complex design of the supporting steel frame and truss structure of the greenhouse, and excessive 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
