Abstract
The utility model belongs to the technical field of farmland irrigation, in particular to a pointer type quantitative irrigation indicator. The indicator comprises a circular measuring needle protective cylinder with the bottom or the side wall fixed on the ground surface and the inside provided with a cavity with an opening on the top, and a floating plate arranged in the cavity of the measuring needle protective cylinder; the bottom of a measuring needle is fixed on the floating plate; the bottom of the circular measuring needle protective cylinder is communicated with the outside a hole; scales are arranged on the surface of the measuring needle. The indicator solves the problems of the prior art that the irrigation is not uniform or precise irrigation cannot be realized, and has the advantages of greatly improvement of farmland irrigation uniformity, economy, durability, water saving and yield increase after use.
Description
Affiliated technical field
The utility model belongs to the field irrigation technical field, is meant a kind of pointer quantifying irrigation indicating device especially.
Background technology
The crops quantifying irrigation has a lot of technology, concludes and gets up to have substantially three classes: the one, under certain irrigation by pumping appointed condition, determine irrigation quantity according to water supply time; The 2nd, at the water source head end water yield instrument, instrument are installed, quantifying irrigation is carried out in indication according to instrument; The 3rd, according to the crop of result of study enforcement for many years quantifying irrigation.This three types of technology can both play the water-saving effect of crop quantifying irrigation, but its relative merits are respectively arranged:
The first kind, fixing water lift equipment is determined the irrigation quantity method according to irrigation time, its advantage is to grasp than being easier to, as long as there is a time counting table just can use.But because underground water table causes that with the different of water lift time the unit interval aquifer yield is inconsistent with seasonal variations is different, this method by the time metering can not realize accurate irrigation.
Second class is installed instrument at the water source head end and is carried out the quantifying irrigation method, and this method is one of the maximum method of using at present.Its advantage is accurately to hold irrigation quantity, and remedied because water lift time, aquifer yield different restriction that season, difference caused, but since from the water source to the farmland water delivery distance difference of each irrigation district and the smooth degree in ground, farmland different, the actual amount of water difference of each irrigation district, farmland makes the irrigation uniformity difference.
The 3rd class is implemented crop quantifying irrigation method according to result of study for many years, this method than empirical irrigation more science some, but still be the blank stage of quantifying irrigation, irrigate the demand for development incompatibility with modern agriculture.
The utility model content
The purpose of this utility model is to provide a kind of pointer quantifying irrigation indicating device of installing in the field irrigation district, is not subjected to water source aquifer yield, water delivery distance, the restriction of irrigation season, can improve the field irrigation uniformity coefficient greatly and realize the accurate irrigation in farmland.
Overall technology structure of the present utility model is:
Pointer-type quantifying irrigation indicating device, comprise the bottom or sidewall be fixed in the face of land and in establish open-topped cavity ring-type gauge needle protection cylinder 4, be located at the kickboard 3 in gauge needle protection cylinder 4 internal cavities, gauge needle 2 bottoms are fixed on the kickboard 3, ring-type gauge needle protection cylinder 4 bottoms are by hole 5 and external communications, and gauge needle 2 surface marks have scale.
Concrete structure design of the present utility model also has:
For guaranteeing that gauge needle protection cylinder 4 is fixed in the face of land better, gauge needle protection cylinder 4 can select for use the bigger material of density (as metal) to make, but more preferred design proposal is: gauge needle protection cylinder 4 bottoms are provided with protection cylinder fixed bar 6, and gauge needle protection cylinder 4 is fixed in the face of land by protection cylinder fixed bar 6.To guarantee that gauge needle protection cylinder 4 is unlikely to produce unsettled situation.
For guaranteeing that the kickboard 3 that has gauge needle 2 can successfully float with the rising of water level in the gauge needle protection cylinder 4, the open top of gauge needle protection cylinder 4 is greater than the external diameter of gauge needle 2.
Shelve and reduce the interference of ground surface soil to its motion for the level that guarantees kickboard 3, the bottom of gauge needle protection cylinder 4 is provided with base plate, and kickboard 3 places plate upper surface.
For guaranteeing the structural strength of gauge needle protection cylinder 4, the water level that satisfies simultaneously in its inner chamber is consistent with the outside, and hole 5 preferred structures are designed to: hole 5 is annular spread at interval at gauge needle protection cylinder 4 sidewalls.
The obtained technical progress of the utility model is:
1, the utility model is placed on irrigation border Tanaka, is not subjected to water source aquifer yield, water delivery distance, the restriction of irrigation season, can improve the field irrigation uniformity coefficient greatly.
2, the utility model is according to the field water position-finding water yield, than in the past to measure the equipment of the water yield according to current more economical durable.
3, after testing, confirm, use the utility model can improve the field irrigation uniformity coefficient more than 10%, water saving about 20%, plant growth evenly improves output about 10%.
