Abstract
The utility model relates to an auxiliary device of sprinklers, in particular to a velocity compensation device of a sprinkler. The velocity compensation device of the sprinkler structurally comprises a minitype stepping motor which is connected to a small gear, the small gear is meshed with the gear teeth of a sector gear, the sector gear is mounted on a governor rod of a water turbine, a single-chip microcomputer is connected with the minitype stepping motor and a calandria roller, a nylon roller is arranged at one end of the calandria roller, the nylon roller is provided with an induction component, and a bearing is arranged between the calandria roller and a supporting shaft. Compared with the prior art, the velocity compensation device of the sprinkler can directly detect the linear speed of recycling of a PE pipe, and has the advantages of being simple in structure, flexible in speed governing, good in velocity compensation performance and the like.
Description
Technical field
The utility model relates to a kind of irrigation sprinkler auxiliary equipment, especially a kind of irrigation sprinkler speed compensation device.
Background technology
Reel sprinkling irrigation machine is when irrigating recovery, the angular speed that provides due to the power source hydroturbine is constant, increase along with the PE pipe number of plies in removal process causes the recovery speed of PE pipe more and more faster, finally cause irrigating lack of homogeneity, so, just need to use speed compensation device when irrigation sprinkler is irrigated.At present, on market, speed compensation device is to respond to the PE pipe number of plies with linkage, and by the chain reaction of linkage, automatically adjusts the hydroturbine handle, to reach by adjusting the hydroturbine rotating speed, finally realizes the uniform purpose of PE pipe recovery speed.This kind mode of speed regulation complex structure, error is large, the velocity compensation poor performance.
Summary of the invention
Technical assignment of the present utility model is the weak point for above present situation, and a kind of simple in structure, a kind of irrigation sprinkler speed compensation device that error is little is provided.Adopted technical scheme to be by solving its technical problem: the utility model structure comprises that micro-step motor connects pinion, the gear teeth interlock of pinion and sector gear, and sector gear is arranged on the speed control rod of hydroturbine; Single-chip microcomputer connects micro-step motor and comb roller; One end of comb roller arranges nylon roller, and inductive means is set on nylon roller, between comb roller and back shaft, bearing is set.
A kind of irrigation sprinkler speed compensation device of the present utility model compared to the prior art, have following characteristics: the utility model is logical simple in structure, reliable, by the parts such as micro-step motor are set, realized speed governing purpose more accurately, by single-chip microcomputer and comb roller are set, make detection more direct, the speed governing compensation performance is better.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is a kind of structural representation of irrigation sprinkler speed compensation device.
In figure: 1, micro-step motor, 2, pinion, 3, sector gear, 4, the speed control rod of hydroturbine, 5, nylon roller, 6, inductive means, 7, the comb roller, 8, bearing, 9, back shaft, 10, single-chip microcomputer.
Embodiment
Be described in detail below with reference to 1 pair of a kind of irrigation sprinkler speed compensation device of Figure of description.
A kind of irrigation sprinkler speed compensation device of the present utility model, structure comprise speed adjusting device and PE pipeline speed acquisition device.
The speed adjusting device structure comprises: micro-step motor 1 connects pinion 2, the gear teeth interlock of pinion 2 and sector gear 3, and sector gear 3 is arranged on the speed control rod 4 of hydroturbine.The utility model drives pinion 2 by micro-step motor 1, and pinion 2 drives sector gears 3, more further drives the rotation of the speed control rod 4 of hydroturbine, with change, enters the discharge of hydroturbine and then realizes the speed governing of hydroturbine.
PE pipeline speed acquisition apparatus structure comprises: be connected to the single-chip microcomputer 10 of micro-step motor 1, single-chip microcomputer 10 connects comb roller 7; One end of comb roller 7 arranges nylon roller 5, and inductive means 6 is set on nylon roller 5, between comb roller 7 and back shaft 9, bearing 8 is set.
In use, back shaft 9 is arranged on the fixed pipe support of PE pipe both sides the utility model.PE manages while reclaiming and the frictional force that produces between comb roller 7 drives nylon roller 5 rollings, by the inductive means 6 on progressive inductive switching nylon roller 5, and the rolling number of turns of collection comb roller 7.Then can calculate the girth summation of rolling at the appointed time, the i.e. sliding distance of PE pipe by single-chip microcomputer 10.Just can converse the recovery speed of PE pipe, and then by data wire, to micro-step motor 1, send the open and close instruction.Carry out the adjustment of hydroturbine speed, until within actual recovered speed is in the deviation range that given recovery speed allows.
