Embodiment Construction

[0012] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0013] figure 1 The joint-connected spray rod of the manual sprayer shown is a two-section rod, which includes an outer nozzle 1, a main nozzle 2, a middle nozzle 3, an inner nozzle 4, a joint 5 and an auxiliary nozzle 6. The outer spray head 1 is a two-way structure, that is, the interface directly communicates with the downwardly inclined nozzle. The middle nozzle 3 and the inner nozzle 4 are of three-way structure, and the connections at both ends are straight-through pipes, and the straight-through pipe communicates with the downwardly inclined nozzle. The two main connecting pipes 2 are installed coaxially in series from two directions and are sealed to connect the middle nozzle 3 , the other ends of the two main connecting pipes 2 are respectively sealed and connected to the outer nozzle 1 and the inner nozzle 4 to form a main ro...

Abstract

The invention discloses a section-type spray rod of a manual sprayer, and the section-type spray rod comprises an outer spray head, main connection pipes, a middle spray head, inner spray heads, a connector and an auxiliary connection pipe. The outer spray head is a two-way structure, the middle spray head and the inner spray head are respectively of a three-way structure, two main connection pipes are respectively installed in serial in the axial direction from two directions and in sealing connection with the middle spray head, and the other ends of the two main connection pipes are respectively connected with the outer spray head and the inner spray head in a sealing way to form a main rod. Two ends of the auxiliary connection pipe are respectively connected with the connector and another inner spray head in a sealing way to form an auxiliary rod to be reserved. An interface of one end of the inner spray head, facing outwards, is an inner threaded hole, and the threaded hole is matched with outer threads of the connector on an outlet of the manual sprayer or on the auxiliary rod. The distance among the outer spray head, the middle spray head and the inner spray head is 250mm to 320mm, and nozzles of all spray heads are inclined downwards. Due to the adoption of the section-type structure, the spray rod can be assembled or disassembled by different users according to the real situation, and the pest control efficiency can be increased.

Description

technical field [0001] The invention relates to an agricultural implement, in particular to a joint-type spray rod of a manual sprayer. Background technique [0002] A hand sprayer is a small device that sprays pesticides manually. The prepared liquid pesticide is manually pressurized by the sprayer and sprayed out from the nozzle on the spray rod held by the farmer. Whether the structure of the spray rod is reasonable or not is related to the efficiency and effect of pesticide spraying. Commercial spray rods on the market are of an integral tube structure, with 2 to 3 downward-facing nozzles centrally fixed at the end of the rod. When spraying pesticides, the farmer swings the spray rod left and right while walking, and all plants within the range covered by the spray rod can be harvested. Mist pesticide spraying. Because the commercial spray rods on the market have a fixed structure and the nozzles are concentrated, the pesticide coverage area sprayed by each swing is sm...
