DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: Example: Reference Figure 1 , the present embodiment provides a porous spray device suitable for tobacco planting; it includes a shoulder-type water tank 1 for storing pesticide solution; a water pump is installed on the water tank 1; the water pump is powered by a power supply built in the water tank 1, and a hose 3 is provided at the discharge end of the water pump; the other end of the hose 3 is connected with the discharge pipe 5 through a guide pipe 4; a plurality of atomizing nozzles 6 are provided on the discharge pipe 5; a connecting block 7 is provided in the middle of the discharge pipe 5; the connecting block 7 is installed on the top of a telescopic support 8; the telescopic support 8 is arranged vertically, and its lower end is installed on an auxiliary bracket 9; a roller 10 is installed at the bottom of the auxiliary bracket 9; a telescopic rod 11 is also hingedly installed on the auxiliary bracket 9; the telescopic rod 11 is located below the guide pipe 4, and a hand-push handle 12 is provided at the other end of the telescopic rod 11; a clamp 13 capable of clamping the guide pipe 4 is provided on the hand-push handle 12.

[0016] The number of the atomizing nozzles 6 is an even number, and the atomizing nozzles 6 are symmetrically arranged on the left and right sides of the discharge pipe 5. The symmetrical arrangement of the atomizing nozzles is mainly to ensure the balance of the working state.

[0017] refer to Figure 3 A groove having a size matching that of the discharge pipe 5 is provided on the top of the telescopic support 8, and the connecting block 7 is a structure similar to a clamp; through holes are provided on the side surfaces of the opposite ends of the connecting block 7 and the telescopic support 8, and the discharge pipe 5 is detachably clamped between the connecting block 7 and the telescopic support 8 by a bolt and nut assembly. The telescopic support is used in this embodiment to adjust the height of the atomizing nozzle according to the height of crops at different growth stages, thereby enhancing the spraying effect.

[0018] refer to Figure 4 A pair of ear plates 14 are provided on the auxiliary bracket 9; one end of the telescopic rod 11 is mounted on the ear plate 14. A pair of flanges are provided on one end side of the telescopic rod 11; the flange is arranged opposite to the end surface of the ear plate 14, and a number of positioning holes are provided on the flange and the ear plate 14; the positioning holes are distributed with the axis of the flange as the symmetrical center; the telescopic rod 11 is detachably connected to the ear plate 14 at the positioning holes through a bolt assembly. There are 8 positioning holes on a single ear plate in this embodiment. The ear plate and flange are provided to adjust the lifting angle of the telescopic rod according to the use requirements, so as to provide effective support effect for the discharge pipe and the guide pipe limited by different telescopic support platform heights.

[0019] An over-the-shoulder strap 2 is also provided on the water tank 1; a buckle is provided on the telescopic rod 11 at a position close to the telescopic support platform 8; one end of the over-the-shoulder strap 2 is detachably connected to the buckle.

[0020] The auxiliary bracket 9 is a box structure with a hollow interior; the size of the cavity inside the box is consistent with the size of the water tank 1; and a through hole is also left on the auxiliary bracket 9 for the hose to pass through.

[0021] The hose 3 and the discharge pipe 5 are both detachably connected to the two ends of the guide pipe 4, and the hose 3 can be directly connected to the discharge pipe 5. By designing the two ends of the guide pipe to be detachable, it is possible to directly connect the hose to the discharge pipe when the water tank needs to be placed in the auxiliary bracket, so that the guide pipe can be put away and the hose can be directly connected to the discharge pipe. The discharge pipe 5 is a segmented straight pipe structure formed by splicing a plurality of unit pipes. By setting the discharge pipe as a spliced ​​segmented structure, it is convenient to adjust the length of the discharge pipe according to actual needs, so as to adjust the output position of the atomizing nozzle, thereby meeting the corresponding spraying needs on ridges of different widths.

After that, the operator carries the water tank, connects the hose to the guide pipe and starts the spraying operation. The operator can push the hand push handle to drive the auxiliary bracket forward to achieve continuous spraying, thereby reducing the operator's work intensity.
