Problems solved by technology

The problem is that these optical speed measuring devices cannot measure the uniformity of the rotation of the nozzle within a week
The problem is that once the arrangement of the reed switch or the proximity switch is fixed, it is difficult to change it, and the overall layout needs to be modified when it is changed.

Embodiment Construction

[0012] see figure 1 and figure 2 , the present embodiment provides a measuring device for the rotational characteristics and rotating speed of a rotary spray head for sprinkling irrigation, including a rocker spray head 5, and a number of reflective materials with the same width are evenly adhered to the outer wall of the spray head body of the rocker spray head 5 4. There is a disk 1 on the nozzle base of the rocker nozzle 5, and a laser 3 is fixed on the disk 1. The reflective material 4 and the laser emission port of the laser 3 are on the same level. The laser 3 passes through the counter 6 and the pulse signal. The detection device 7 is connected, and the laser 3 , the counter 6 and the pulse signal detection device 7 are powered by a power supply 8 .

[0013] In this embodiment, the laser 3 adopts an element integrating laser emission and laser reception to perform laser emission and reception.

[0014] The number of reflective materials 4 is 8~12

[0015] The light ...

Abstract

The invention discloses a device for measuring rotating property and rotating speed of a rotating sprinkler for sprinkling irrigation. The device comprises an impact drive sprinkler, and a plurality of reflective materials with the same width are uniformly stuck to the outer wall of a sprinkler body of the impact drive sprinkler; and a disc is arranged on a sprinkler pedestal of the impact drive sprinkler, a laser device is fixed on the disc, the reflective materials and the laser emitting port of the laser device are positioned on the same horizontal plane, and the laser device is connected with a pulse signal detecting device through a counter. The device is simple in structure, and overcomes the defect that the conventional rotating speed measuring device cannot measure the rotating speed change of the sprinkler rotating in one cycle. The device for measuring the rotating property and the rotating speed of the sprinkler can be applied to test of the sprinkler for the sprinkling irrigation.

Description

technical field [0001] The invention belongs to an improvement of the existing rotary sprinkler head rotational speed measuring device, in particular to a measuring device for the rotational characteristics and rotational speed of the rotary sprinkler head for sprinkling irrigation. Background technique [0002] In agricultural irrigation and industrial production, the rotary nozzle is one of the most widely used nozzles in the current sprinkler irrigation technology, and its motion characteristics and speed are the main factors affecting its performance. The speed of the nozzle has a great influence on the uniformity of spraying. If the speed of the nozzle is small in a certain position during the rotation of the nozzle, the spraying time will be long and the spraying amount will be large; Therefore, the measurement of the motion characteristics and rotational speed of the nozzle has become one of the main tasks in the research of the nozzle performance test. [0003] The ...
