Abstract
The utility model discloses a spray gun belongs to injection apparatus technical field, spray gun body including a tubular shell structure, this internal liquid inlet channel, powder channel outlet and hybrid channel of being equipped with of spray gun, liquid inlet channel's one end with the hybrid channel intercommunication, the other end and external liquid supply source intercommunication, powder channel outlet's one end with the hybrid channel intercommunication, the other end thoughtlessly communicates with external dust supply, liquid inlet channel is provided with with mixed passage junction can make the pressure boost that produces the negative pressure in powder channel outlet's exit. The utility model discloses a pressure boost section is in powder channel outlet exit production negative pressure to suck the powder and liquid mixing, reach automatic purpose of joining in marriage liquid, the disposable completion is joined in marriage the liquid operation and is sprayed the operation, saved operating sequence, improved operating efficiency, reduced operation workman's intensity of labour by a wide margin, and the suction of powder operation no longer needs power drive, has saved the energy consumption.
Description
Technical field
This utility model belongs to injection apparatus technical field, is specifically related to a kind of spray that directly liquid and powder can be carried out and mixing
Rifle.
Background technology
The situation needing to carry out by a certain percentage solid-liquid married operation during use is more universal, such as the preparation of insecticide, husky oar
Preparations etc., the use of prior art solidliquid mixture includes that dosing operation and two independent steps of spraying are gathered, carries out dosing behaviour
As time cannot be carried out spraying, carry out cannot be carried out during spraying dosing operation, and basic by being accomplished manually, need to expend
A large amount of human and material resources, financial resources, labor intensity is big, efficiency is low.
If a kind of apparatus and method that can carry out dosing operation and spraying can be proposed seem and be even more important simultaneously.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of spray gun with dosing function, to solve prior art existence
Cannot perform to cause running cost problem high, inefficient due to dosing operation and spraying simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
Spray gun, including the gun body of a tubular casing structure, is provided with feed pathway, powder channel and mixes in described gun body
Closing passage, one end of described feed pathway connects with described hybrid channel, and the other end connects with environmental liquids source of supply, described powder
One end of end passage connects with described hybrid channel, and the other end leads to external dust supply mixed connection, and described feed pathway is led to mixing
Junction, road is provided with the boost section that can make to produce negative pressure in the exit of powder channel.
Further, described boost section is a tapered section, and the size of described feed pathway is identical with the big end of described tapered section, described
The size of hybrid channel is identical with the small end of described tapered section.
Further, the tapering of described tapered section is 10-40 °.
The beneficial effects of the utility model are:
This utility model is by arranging feed pathway, powder channel and hybrid channel, and sets between feed pathway and hybrid channel
Put boost section, make to produce in powder channel exit negative pressure, thus powder is sucked and liquid mixing, reach the mesh of automatic liquid matching
, disposably complete dosing operation and spraying, save operation sequence, improve operating efficiency, operative employee is greatly reduced
The labor intensity of people, and powder suction operation be no longer necessary to power drive, save energy consumption.
Other advantages of the present utility model, target and feature will be illustrated to a certain extent in the following description,
And to a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or
Person can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be by following
Description realizes and obtains.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, this utility model provides drawings described below to enter
Row explanation:
Fig. 1 is the structural representation of this utility model spray gun.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As it is shown in figure 1, the spray gun 1 of the present embodiment, including the gun body of a tubular casing structure, set in described gun body
Having feed pathway 2, powder channel 3 and hybrid channel 4, one end of feed pathway 2 connects with hybrid channel 4, and the other end is with outer
Boundary's liquid source of supply connection, one end of powder channel 3 connects with hybrid channel 4, and the other end leads to external dust supply mixed connection,
Feed pathway 2 and junction, hybrid channel 4 are provided with the boost section 5 that can make to produce negative pressure in the exit of powder channel, specifically
, boost section 5 is a tapered section, and its tapering α is 10-40 °, can reach optimal suction effect, the feed liquor of the present embodiment
The size of passage 2 is identical with the big end of tapered section, and the size of hybrid channel is identical with the small end of tapered section, makes hybrid channel keep
Stable pressure-reduction level, is beneficial to the lasting suction to powder, saves energy consumption.
The present embodiment is by arranging feed pathway, powder channel and hybrid channel, and arranges between feed pathway and hybrid channel
Boost section, makes to produce in powder channel exit negative pressure, thus is sucked and liquid mixing by powder, reach the purpose of automatic liquid matching,
Disposably complete dosing operation and spraying, save operation sequence, improve operating efficiency, be greatly reduced operator's
Labor intensity, and powder suction operation be no longer necessary to power drive, save energy consumption.
It addition, the gun body of the present embodiment can take overall structure or combinative structure as required.
Finally illustrating, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, although passing through
This utility model is described in detail by above preferred embodiment, it is to be understood by those skilled in the art that can be
In form and it is made various change, without departing from this utility model claims limited range in details.
