Abstract
The invention discloses a fine adjustment device for positive and negative selecting nozzles for inserts of drip irrigation belts. An adjusting screw rod is positioned outside a coaming; the upper end of the adjusting screw rod is arranged in a via hole of a frame platform; the lower end of the adjusting screw rod is arranged in a threaded hole of a nozzle seat; a screw rod positioner is positioned on the upper surface of the frame platform, and a U-shaped opening of the screw rod positioner is clamped in a clamping groove at the periphery of the adjusting screw rod; the screw rod positioner is fixed on the upper surface of a platform of a frame 1; and the upper surface of the nozzle seat is provided with an adjusting screw rod threaded blind hole. According to the fine adjustment device, the adjusting screw rod is fixed at the upper end of the frame through a screw, and the groove on the adjusting screw rod is clamped and matched with the U-shaped groove of the screw rod positioner, so that the adjusting screw rod only can rotate but cannot move up and down, and when the adjusting screw rod rotates a circle, the nozzle seat fixedly connected with the adjusting screw rod is ascended or descended 0.5 millimeter; and therefore, the nozzles are finely adjusted. The fine adjusting device has the characteristics of high adjusting accuracy, simple and compact structure, low manufacturing cost, convenience for use, and no need of maintenance.
Description
Technical field
The present invention relates to water saving fixtures production line, specifically the positive and negative chip select valve of the centrifugal interior empiecement of a kind of drip-irrigation belt production line position regulator.
Background technology
Interior empiecement drip irrigation zone first operation when producing must be chosen to interior empiecement to face up, and reverse side just can enter down to operation downwards, and interior empiecement front is smooth and reverse side is designed to the boss of 0.2 millimeter of protrusion, by centrifugal sheet selection machine, is selected.Principle is by centrifugal force, interior empiecement to be thrown and had on the centrifugal rotation slide rail of surrounding edge, on surrounding edge, be provided with five groups of valves, the thin air-flow of every group of valve be adjusted to just allow interior empiecement front by and reverse side owing to exceeding 0.2 millimeter, be blown slide rail and enter Overlapping Areas.At present, the valve on the interior centrifugal sheet selection machine of empiecement all adopts hand to take adjustment mode both at home and abroad, and five groups of valves can not exceed the 0.2 millimeter of scope in top, interior empiecement front, and adjustment is wasted time and energy, and precision is lower, general operation personnel adjustment difficulty, and efficiency is too low.
Summary of the invention
For overcoming the adjustment difficulty existing in prior art, adjust the low and inefficient deficiency of precision, the present invention proposes the positive and negative micromatic setting that selects valve of empiecement in a kind of drip irrigation zone.
The present invention is comprised of adjusting screw(rod), screw rod locator, frame and valve nozzle boss.Adjusting screw(rod) is positioned at coaming plate outside, and upper end is arranged in the via hole on framework platform, and the lower end of adjusting screw(rod) is arranged in the screwed hole on valve nozzle boss.Screw rod locator is positioned at framework platform upper surface, and in the draw-in groove of " U " shape open card of described screw rod locator on adjusting screw(rod) circumference.Screw rod locator is fixed on to frame 1 platform upper surface.Upper surface at valve nozzle boss has the adjusting screw(rod) of installation tapped blind hole.
" U " shape opening of described screw rod locator is positioned at one end of this screw rod locator.The other end at described screw rod locator has fixed via.
There is external screw thread adjusting screw(rod) lower end.Excircle at another end ring adjusting screw(rod) of adjusting screw(rod) has the draw-in groove coordinating with screw rod locator.
In the present invention, by screw, adjusting screw(rod) is fixed on to frame upper end, because the groove on adjusting screw(rod) blocks and coordinates mutually with screw rod locator U-lag, adjusting screw(rod) can only be rotated and can not move up and down, adjusting screw(rod) often revolves and turns around, make the valve nozzle boss being connected with this adjusting screw(rod) rise or decline 0.5 millimeter, thereby realize the fine setting to valve.
By the present invention, make the adjustment of valve on the centrifugal sheet selection machine of interior empiecement simple, by past specialty adjustment personnel, nearly two hours adjustment time became common operating personnel and can complete for five minutes, efficiency improves 20 times of left and right.The present invention have adjust accurately high, compact conformation is simple, low cost of manufacture and easy to use, maintenance-free feature.

The specific embodiment
Valve mechanical fine adjustment device is comprised of adjusting screw(rod) 2, screw rod locator 4, frame 1, valve nozzle boss 5, valve 6 and interior empiecement 7.
Adjusting screw(rod) 2 is positioned at coaming plate outside, and upper end is arranged in the via hole on frame 1 platform, and the lower end of adjusting screw(rod) 2 is arranged in the screwed hole on valve nozzle boss 5.Screw rod locator 4 is positioned at frame 1 platform upper surface, and in the draw-in groove of " U " shape open card of described screw rod locator 4 on adjusting screw(rod) 2 circumference; By screw 3, screw rod locator 4 is fixed on to frame 1 platform upper surface.
Valve nozzle boss 5 is that prior art is improved and obtained.Described valve nozzle boss 5 is block.A side surface at valve nozzle boss 5 has the screwed hole being connected with coaming plate; The installation through hole that has valve 6 in valve nozzle boss 5 bottoms, and by screw, this valve 6 is fixing.Valve nozzle boss 5 is characterised in that, is processed with tapped blind hole, for adjusting screw(rod) 2 is installed at the upper surface of valve nozzle boss 5.
Adjusting screw(rod) 2 is circular rod-shaped.There is external screw thread these adjusting screw(rod) 2 lower ends, and upper end is six square toes, so that spanner adjustment.Below six square toes of adjusting screw(rod) 2, ring adjusting screw(rod) 2 excircle have the draw-in groove coordinating with screw rod locator 4.
In the present embodiment, by screw 3, adjusting screw(rod) 2 is fixed on to frame upper end, because the groove on adjusting screw(rod) 2 blocks and coordinates mutually with screw rod locator U-lag, adjusting screw(rod) 2 can only be rotated and can not move up and down, adjusting screw(rod) 2 often revolves and turns around, make the valve nozzle boss 5 being connected with this adjusting screw(rod) 2 rise or decline 0.5 millimeter, thereby realize the fine setting to valve.
