Technical Field

The invention relates to the technical field of agricultural mechanical equipment, in particular to a connecting spray head with double connecting joints.

Background

In the existing agricultural machinery, a spray head used in a spray or liquid spray pipe is generally a common spray head, and the spray head is provided with only one spray hole, so that the spray is concentrated, the spray range is small, and the spray head is not ideal.

Meanwhile, the existing spray head has only one spray hole with a larger diameter ratio, so that impurities can easily enter the spray head to block the spray hole, thereby influencing the spraying effect.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a connecting spray head with double connecting joints, which is provided with two sub connecting joints, realizes multi-angle spraying and increases the spraying range, and simultaneously, an inserting spray pipe can move up and down along a central through hole, can extrude sundries blocked at the upper end of the central through hole, is not easy to make large-particle sundries enter the sub connecting joints, and has good spraying effect.

The scheme for solving the technical problems is as follows:

a connecting spray head with double connecting joints comprises a main connecting screw pipe, extension screw connecting sleeves are formed on the left side and the right side of the top end of the main connecting screw pipe, branch connecting joints are screwed on the extension screw connecting sleeves, a central through hole is formed in the middle of a top plate of each branch connecting joint, a lifting plate is inserted in each branch connecting joint, an inserting spray pipe is formed in the middle of the top surface of each lifting plate, and the inserting spray pipes are inserted in the central through holes;

the inserting spray pipe is inserted and sleeved with a buffer spring, the top end of the buffer spring is stressed on the bottom surface of the top plate of the branch connector, and the bottom end of the buffer spring is stressed on the top surface of the lifting plate;

and a plurality of water spraying through holes are formed in the top plate of the inserting spray pipe.

And a radial extension edge is formed on the outer side wall of the middle part of the sub-connector, and the bottom surface of the radial extension edge is pressed against the top surface of the extension screw sleeve.

Be fixed with wear-resisting self-lubricating cover on the inside wall of branch connector, wear-resisting self-lubricating cover's inside wall is hugged closely to the lateral wall of lifter plate.

A plurality of guide rods are formed on the bottom surface of the top plate of the sub-connector, and the guide rods are inserted in guide through holes formed in the lifting plate.

And a self-lubricating sleeve is fixed on the inner side wall of the guide through hole, and the guide rod is inserted in the self-lubricating sleeve.

The inserting spray pipe is communicated with a liquid inlet through hole formed in the middle of the lifting plate.

And a middle radial extending edge is formed on the outer side wall of the middle part of the main connecting spiral pipe.

The middle part of the main connecting solenoid is nested with a sealing ring, and the top surface of the sealing ring is pressed against the bottom surface of the middle part radial extension edge.

The invention has the following outstanding effects: compared with the prior art, it has two branch connectors, realizes the multi-angle and sprays, increases the spray regime, and simultaneously, its grafting spray tube that has can reciprocate along central through-hole, can extrude the debris of stifled upper end department at central through-hole, also is difficult for making large granule debris get into in the branch connector in addition, and it sprays effectually.
