Abstract

The utility model relates to sprayers and particularly provides a multi-section and multi-nozzle sprayer which is mainly characterized by adopting a multi-section and multi-nozzle spray beam, wherein small-size nozzles are formed on the tubular wall of the spray beam; a fixing sleeve is sleeved on the beam body; a one-way sealing valve cup is arranged at the near end of the spray beam; the near end of the spray beam is sleeved in an outer beam; the fixing sleeve is in sealing and fastening connection with the opening of the outer beam which serves as the spray beam, and the like; and the outmost beam is connected with the hose of the sprayer. The multi-section and multi-nozzle sprayer has the advantages of high portability and wide applicable range and improves the operating efficiency, and therefore, the multi-section and multi-nozzle sprayer is applicable in spraying in a two-dimensional, three-dimensional and interlaced manner.

Description

The many nozzle sprayers of more piece bar

Technical field

The utility model belongs to field of work machines, relates to sprayer, is specifically related to the many nozzle sprayers of a kind of more piece bar.

Background technology

Existing sprayer is by the shower nozzle of spray tank by flexible pipe connection spray boom and far-end.Because be subjected to the restriction of spray bar length and shower nozzle quantity, position, it is low to exist spraying efficiency, the defective that spraying swath can not be regulated.

The utility model content

The inventor finds that existing sprayer exists above-mentioned defective in social practice, through investigation and research, purpose is to provide a kind of more piece bar many nozzle sprayers, can improve spraying operation efficient, and can also regulate the sprinkling amplitude.

Technical solution adopted in the utility model is the many nozzle sprayers of a kind of more piece bar of design, its structure comprises: the sprayer staving, the connection flexible pipe that staving is drawn, the shower nozzle of spray boom and spray boom far-end, its spray boom adopts many shower nozzles of more piece bar spray boom, on the tube wall of spray boom, offer at least one small-sized shower nozzle, connect at the near-end of spray boom and to establish the one-way sealing valve, the near-end of spray boom is gone in the outer bar together with the one-way sealing valve pocket, a sheathed fixed cover on the shaft of spray boom, fixed cover on the spray boom shaft is fastened and connected by gasket seal with the mouth of pipe of outer bar, constitutes two many shower nozzles of pole spray booms; By that analogy, should be connected with the outermost bar as spray boom by outer bar again, constitute many shower nozzles of more piece bar spray boom, the outermost bar is connected with the sprayer flexible pipe, constitutes the many nozzle sprayers of more piece bar.

In order to prevent that spray boom from freely rotating in the bar outside, faying face between one-way sealing valve and the outer bar inwall is many prismatics, add cushion cover between fixed cover and the spray boom outer wall,, and do not influence artificial rotation or pull telescopic slide with the anti-rotation resistance between the increase faying face.

For the ease of grasping spray boom pull telescopic level, the bit line of also on described spray boom, limiting.

During use, if closely spray among a small circle, a certain spray boom outside sending into accordingly, the fixed cover cunning in the bar, can be able to be used a small amount of shower nozzle as required, the soup of returning this moment in the outer bar that other small-sized shower nozzle sprayed refluxes through the check valve bowl, and the unlikely consumption of soup and pressure is lost; If spray at a distance in a big way, a certain spray boom can be pulled out outer bar, in the process of pulling out, sap cavity volume between the inside and outside bar dwindles gradually, and pressure raises, when pressure is higher than the boom pipe internal pressure, soup can reflux through the check valve bowl, sprays amplitude range thereby regulate, and improves spraying operation efficient.Be applicable to that the plane sprays, the three-dimensional sprinkling, interlacing is sprayed, have easy to carry, applied widely, the remarkable advantage that operating efficiency improves.

Description of drawings

Fig. 1 represents many shower nozzles of more piece bar spray boom structure partial cross-sectional schematic of the many nozzle sprayers of the utility model more piece bar.

The specific embodiment

Reach embodiment in conjunction with the accompanying drawings, further specify the concrete structure of the many nozzle sprayers of the utility model more piece bar, its feature and advantage are clearer.

The embodiment 1 of the many nozzle sprayers of the utility model more piece bar, referring to Fig. 1, its structure comprises: sprayer staving (not shown), the flexible pipe (not shown) that staving is drawn, the shower nozzle 1 of spray boom 2 and spray boom 2 far-ends (right-hand member), on the tube wall of spray boom 2, offer 2 small-sized

shower nozzles

7,8, connect at the near-end (left end) of spray boom 1 and to establish unidirectional flapper-type seal valve bowl 4, the left end of spray boom 1 inserts in the outer bar 5 together with unidirectional flapper-type seal valve bowl 4, a sheathed fixed cover 3 on the shaft of spray boom 1, fixed cover 3 is fastened by screw thread and gasket seal with the outer bar 5 right-hand member mouths of pipe and is tightly connected, the outer bar 5 left end mouths of pipe are connected with the flexible pipe (not shown) that staving is drawn, and constitute the sprayer of a kind of two poles of the utility model three shower nozzles; By that analogy, as spray boom, outermost bar and staving flexible pipe connect and compose the many nozzle sprayers of more piece bar with outer bar 5.

The embodiment 2 of the many nozzle sprayers of the utility model more piece bar, referring to Fig. 1, its structure comprises: in the structure of embodiment 1, described unidirectional flapper-type seal valve bowl 4 is many prismatics with the faying face that contacts between outer bar 5 inwalls, lining is established cushion cover between fixed cover 3 and spray boom 1 outer wall, in order to preventing that spray boom from freely rotating, and do not influence artificial rotation or pull telescopic slide.

The embodiment 3 of the many nozzle sprayers of the utility model more piece bar, referring to Fig. 1, its structure comprises: in the structure of embodiment 1, also carve the bit line 6 of limiting respectively at the both ends of described spray boom.

Claims

1. many nozzle sprayers of more piece bar, comprise the sprayer staving, the connection flexible pipe that staving is drawn, the shower nozzle of spray boom and spray boom far-end, it is characterized in that spray boom adopts many shower nozzles of more piece bar spray boom, on the tube wall of spray boom, offer at least one little shower nozzle, connect at the near-end of spray boom and to establish the one-way sealing valve, the near-end of spray boom is inserted in the outer bar together with one-way sealing valve bowl, a sheathed fixed cover on the shaft of spray boom, fixed cover on the spray boom shaft and outer rod tube mouth are fastened and connected by gasket seal, and outer bar is connected with the outermost bar as spray boom again, by that analogy, the outermost bar is connected with the sprayer flexible pipe.
