Embodiment Construction

[0008] The meter body 1 of the present invention is composed of two parts: a tubular flow channel 2 and a counting chamber 9, and a sealing partition 8 is arranged on the upper wall of the tubular flow channel between the tubular flow channel and the counting chamber. A rotating shaft 4 is installed between the lower walls of the tubular flow channel, and three cup wheels 5 are symmetrically installed on the center line of the water flow on the rotating shaft. A bracket 6 is fixed on the rotating shaft at the same height as the upper wall of the tubular flow channel. There is a certain gap between the two ends of the bracket and the partition to install permanent magnets. A magnetic induction receiver 10 is installed in the counting chamber corresponding to the permanent magnet. The magnetic induction receiver is passed through a wire Connect with an electronic counting display device 11. The above-mentioned induction receiver can also be connected with a mechanical counting d...

Abstract

The invention discloses a spiral cup water meter for agriculture, and it includes a meter body composed of tube-type flow passage and count cavity, a sealed dummy plate was set between the tube-type flow passage and the count cavity above the upper wall of the pipeline, below the dummy plate between with lower wall of tube-type flow passage was a rotating shaft, and cup wheels were symmetrically installed in the center line of on the shaft, in the front of the cup wheels was a streamlined guide plate, a supporting frame was fixed of equal altitude between the shaft and upper wall of tube-type flow passage, between the two ends of the frame and the dummy plate, space was set aside for the installation of permanent magnet, in the count cavity installed with magnetic induction receiver corresponding with the permanent magnet, magnetic induction receiver connected a counting display device. The said counting display device can be electronic counting device or mechanical counting device. The invention use streamlined guide plate and cup wheel, it is uneasy to plug, and can achieve a small headwater loss purpose.

Description

Technical field: [0001] The invention relates to a measuring instrument, in particular to a rotary cup agricultural water meter suitable for farmland irrigation. Background technique: [0002] The existing commonly used irrigation pipe-type metering water meter, the impeller blade is mainly a turbine-type structure, its disadvantages are: large head loss, easy to block, and it is difficult to meet the metering of large-diameter water delivery, and it is not suitable for farmland irrigation with large water flow and poor water quality. Poor usage conditions. Invention content: [0003] The purpose of the present invention is to provide a rotary cup agricultural water meter with small water head loss, long service life and adaptable to the requirement of large-diameter water delivery. [0004] The technical solution of the present invention is accomplished in the following manner, it includes a surface body composed of a tubular flow channel and a counting cavity, and is ch...
