Sprinkling speed detection device and detection method for reel-type sprinkling machine

Abstract

The invention discloses a sprinkling speed detection device and a detection method for a reel-type sprinkling machine. The device comprises a suspension rod arranged on a reel frame. The suspension rod is internally provided with a pre-tensioning spring. Outside the suspension rod, a built-in bearing and a hollow shaft encoder are arranged below the pre-tensioning spring. A compaction rod and a detection wheel are arranged within the interval of the suspension rod. The two ends of the compaction rod pass through the suspension rod to be connected with the lower end of the pre-tensioning spring. A compaction wheel is sleeved onto the compaction rod. One end of the detection wheel is connected with the hollow shaft encoder, and the other end of the detection wheel is connected with the built-in bearing. The hollow shaft encoder is connected with a controller via a signal line. The controller is arranged inside an electric control box. A water outlet pipe is arranged between the compaction wheel and the detection wheel. Based on the device and the method, the sprinkling speed is ensured to be constant, so that the sprinkling uniformity is improved. Therefore, the efficient sprinkling of the sprinkling machine is realized.

Description

technical field [0001] The invention relates to a detection device for farmland irrigation machinery, in particular to a detection device and a detection method for the sprinkling speed of a reel type sprinkler irrigation machine. Background technique [0002] With the rapid development of modern agricultural technology, the reel sprinkler has become a widely used farmland irrigation and drainage equipment. The existing reel sprinkler mainly uses the water pump to generate pressure water to drive the water turbine to generate power, and then drives the The reel is running. [0003] The speed control system of the existing reel type sprinkler irrigation machine is a set of connecting rod mechanism, through which the opening degree of the tongue of the water turbine is controlled to control the speed of the water turbine, and finally control the sprinkling speed of the reel type sprinkler irrigation machine, but the existing There is no device on the sprinkling irrigation mac...

Problems solved by technology

[0003] The speed control system of the existing reel type sprinkler irrigation machine is a set of connecting rod mechanism, through which the opening degree of the tongue of the water turbine is controlled to control the speed of the water turbine, and finally control the sprinkling speed of the reel type sprinkler irrigation machine, but the existing There is no device on the sprinkling irrigation machine to detect the sprinkling speed of the sprinkling machine, that is, the actual sprinkling speed is unknown during operation, and when the sprinkling machine is working, changes in the number of layers of coiled pipes and changes in the working conditions of the sprinkling machine will lead to changes in the sprinkling speed. The sprinkling speed cannot be adjusted in real time, and it is difficult to achieve uniform, uniform and high-efficiency sprinkling irrigation
