Abstract

The invention relates to a sprayer which sprays mist (powder) from the rear direction or the rear side direction. The sprayer comprises a power unit; an output shaft of the power unit passes through a pneumatic positioning disc and is then connected with a fan blade or an eccentric fan; a butterfly disc of an eccentric spray disc is arranged in or at the front end of the fan blade or the eccentric fan; an 'L' shaped liquid medicine recovery device can be arranged at the lower end of the pneumatic positioning disc; the front end of the liquid medicine recovery device is arranged outside the eccentric spray disc and is larger and higher than an air hole. Therefore, the sprayer can spray mist (powder) from the rear direction or the rear side direction, thus solving the problem of human body contactng medicine in mist (powder) spraying process, saving labour, water and oil and greatly improving work efficiency. The sprayer is equipped with a pressure cover with an air outlet that the can resume the original functions of traditional mist (powder) sprayers. Furthermore, the sprayer has simple structure and low cost. The sprayer can be widely used in various power spraying devices, thereby bringing an end to the history that pesticide application damages human body.

Description

A kind of sprayer

Technical field

The present invention relates to the sprayer of a kind of agricultural spraying (powder).

Background technology

At present, the sprayer on the market mainly contains two big classes, and a class is the hand spraying device, and a class is self-powered power spray (powder) device.Power spray (powder) installs its structure and comprises power set, as gasoline engine, motor etc., behind the wind drum, connect fan blade or centrifugal fan on the power set output shaft, producing high-pressure blast causes the big blade of shower nozzle through pipeline and drives vanelets and smash soup and blow out the purpose that mist reaches spraying, centrifugal spraying disk mostly is monolithic, and it still is the monolithic atomizing that mist is hit by vanelets greatly in the biplate gap.The weak point of its existence be the working condition requirement height, can not released liquor, give shipwreck because the people must walk in spray process, the people is had very major injury, and nebulization efficiency is low in soup; Secondly, water consumption is big, the labour intensity height.

Summary of the invention

Its purpose of the present invention just is to provide the sprayer of a kind of spraying (powder), has the nebulization efficiency height, does not hurt sb.'s feelings, and soup is recyclable, and simple in structure, and cost is low.

The technical scheme that realizes above-mentioned purpose and take, the spraying (powder) mouth backwards to or rear side to installation, comprise power set, behind the wind-force positioning disk, connect fan blade or centrifugal fan on the power set output shaft, fan blade or centrifugal fan front end or the built-in centrifugal spraying disk butterfly sheet that is provided with, described wind-force positioning disk lower end can be provided with " L " shape soup retracting device, described soup retracting device front end is located at the centrifugal spraying disk outside, greater than being higher than the wind hole, main air inlet is positioned at the power side, and spraying (powder) mouth is positioned at the centrifugal spraying disk outside.

Compared with prior art, this device has the following advantages:

Since adopted back to or rear side to spraying (powder) people needn't be walked in soup, avoided poisoning may, and water-saving is laborsaving fuel-efficient, operating efficiency improves greatly, and is simple in structure, cost is low, is easy to install.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing.

Accompanying drawing 1 is this apparatus structure principle schematic;

Accompanying drawing 2 is a centrifugal spraying disk structural principle schematic diagram;

Accompanying drawing 3 is the vertical view of Fig. 2.

The specific embodiment

Embodiment, a kind of sprayer is sideways diffusion spraying (powder) backward after backpack is adopted, comprise power set 1, as shown in Figure 1, on power set 1 output shaft through wind-force positioning disk 2, fixed (can be with duct collar) and shaft coupling rotary type are arranged, the back connects fan blade or centrifugal fan 3, fan blade or centrifugal fan 3 front ends or the built-in butterfly dish 6 that is provided with centrifugal spraying disk 4, described wind-force positioning disk 2 lower ends can be provided with " L " shape soup retracting device 5, described soup retracting device 5 front ends are located at centrifugal spraying disk 4 outsides, greater than being higher than hole, geomantic omen 8.

Centrifugal spraying disk 4 is provided with to the butterfly dish 6 in water hole 7 in opposite directions, form superimposed by two or multi-disc center, shown in Fig. 2,3, butterfly dish 6 inside edges are provided with many ditches or hole 9 can have ditch or hole 9 by packing ring, butterfly dish 6 is provided with

filter course

10,10 can replace 9, and the butterfly dish can be plane or concave surface.

Described butterfly dish 6 is provided with 0 ^-A plurality of holes, geomantic omen 8 of crossing.

There was wind hole 8 at centrifugal spraying disk 4 centers and was located at the inboard for water hole more than 7 and were communicated with main air inlet, and centrifugal fan 3 two sides can air intake.

Employing part, fixed wind-force positioning disk blind area reduces the wind-force guide angle makes soup spray to assigned address, general direct interlock power, and air outlet is jet as far as possible.

In its use, the soup of spraying blind area or dropping liquid will be received by soup retracting device 5, and concentrate and handle, backpack is provided with the drum oil drum oil circuit breaker taps (multiple low volume hole and conventional spray holes are arranged) that adapts with it, frame, water pipe, bars such as universal adjustment mechanism are lifted formula lower curtate position of centre of gravity and are provided with the hole and the bolt of fixing act bar and can adjust spray direction up and down, fixedly wind-force positioning disk (can with duct collar) formula has the gland of taking the air port out of and can realize old-fashioned power driven sprayer original function, and the built-in centrifugal spraying disk of centrifugal spraying disk and fan blade or centrifugal fan can use separately respectively.

After backward the gasoline engine cooling air machine of side direction spraying must move and cause starting crosswind fan and can only be located on the magnet, also can import cooling fan housing or water-cooled by main fan, hot blast can not blow to that people, water pipe fixture, shock mitigation system, anhydrous reports control system, illuminator, taps are located at frame left and right sides inferior horn, oil circuit breaker is located at carburetor top, Throttle Opening Control, safety guard is provided with, battery in place, the lead location, the electric switch location, wind powder pipe connections etc., each steam drain point to that side direction spraying (powder) was required backward after main air inlet etc. was.
