Embodiment Construction

[0022] The present invention is described in further detail now in conjunction with accompanying drawing.

[0023] Such as figure 1 As shown, the device for automatically measuring the droplet flow rate of agricultural sprinklers includes a mobile platform 1 and a droplet collection funnel 2 installed on the mobile platform 1 , a liquid pipeline 3 , a liquid level measuring cylinder 4 , and a flow calculation system 5 . The droplet collecting funnel 2 is provided with such as figure 2 The circular double-layer hollowed-out plate 21 shown in the figure prevents the liquid flow from being too impacted, resulting in large fluctuations in the liquid level in the liquid level measuring cylinder 4 . The outlet of the droplet collecting funnel 2 is connected to the inlet of the liquid pipeline 3, the bottom of the liquid level measuring cylinder 4 is provided with a liquid inlet, the outlet of the liquid pipeline 3 is connected to the inlet of the liquid level measuring cylinder 4,...

Description

technical field [0001] The invention belongs to the field of metering, in particular to a device and method for automatically measuring the droplet flow rate of an agricultural sprinkler head. Background technique [0002] Agricultural sprinklers need to conduct accurate droplet flow tests before pesticide spraying operations to detect their spraying performance. At present, the test method of droplet flow test of agricultural nozzles is often completed by measuring cylinder and stopwatch. This measurement method has large errors, low degree of automation, and high labor intensity for test personnel. At the same time, agricultural nozzles may have pesticide residues, which will endanger test personnel. personal safety. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a device and method for automatically measuring the droplet flow rate of an agricultural sprinkler head. [0004] To achieve the above object, th...
