Detailed Description

As shown in fig. 1 to 8, the present invention mainly includes a frame 1, a spraying unit, and medicine boxes 4, and the present invention will be described in detail below with reference to the drawings.

As shown in fig. 1, the frame 1 is a main body part of the present invention, and is used for carrying the spraying unit and the medicine box, and the bottom of the frame is provided with traveling wheels 11 for facilitating the integral traveling. The walking wheel can be driven by the gasoline engine and has a steering function.

As shown in fig. 2, the spraying unit includes a support rod 2 fixed on the top of the rack, a first spraying rod 3, a second spraying rod 31 and a third spraying rod 32 arranged on the support rod, the support rod is a metal rod vertically arranged, and the support rod can be fixed on the top of the rack through bolts. The bracing piece is hollow structure, all is equipped with the mounting hole on the left side wall and the right side wall of bracing piece, and the mounting hole is including being located a first mounting hole of top, a plurality of second mounting hole in the middle of, a third mounting hole of below, and a plurality of second mounting holes are a set of, and the interval of a plurality of second mounting holes between two liang is less than the interval between first mounting hole and the second mounting hole of top, also is less than the interval between third mounting hole and the second mounting hole of below. A first spray rod 3 is fixedly arranged in the first mounting hole, a second spray rod 31 is fixedly arranged in the second mounting hole, and a third spray rod 32 is fixedly arranged in the third mounting hole. The first to third spray bars are all straight bars and are horizontally placed, as shown in fig. 3, an atomizer 33 is provided in the lower surface of the first spray bar, as shown in fig. 4, atomizers 33 are provided in the upper and lower surfaces of the second spray bar, as shown in fig. 5, and an atomizer 33 is provided in the upper surface of the third spray bar. The spray head can spray atomized chemical control agent, the first spray rod sprays downwards, the second spray rod sprays upwards and downwards, and the third spray rod sprays upwards.

A medicine box 4 is fixed at the top of the rack, a prepared chemical control agent is filled in the medicine box, a water pump is arranged in the medicine box or on the rack, the first end of the water pump is arranged in the medicine box to extract the chemical control agent in the medicine box, a multi-way valve is fixed at the second end of the water pump, and hoses 5 are arranged between the multi-way valve and the first spray rod, between the multi-way valve and the second spray rod, and between the multi-way valve and the third spray rod and used for conveying the chemical control agent.

As shown in fig. 8, the second spraying rods are round rods, a plurality of second spraying rods are located in the same vertical plane, and the distance between two adjacent second spraying rods is equal.

As shown in figure 6, in use, the entire apparatus is driven to travel in the field and is positioned between two adjacent rows of corn plants, the first spray bar is positioned above the uppermost leaf of the corn plant, the third spray bar is positioned below the lowermost leaf of the corn plant, and the second spray bar is positioned between the uppermost leaf and the lowermost leaf of the corn plant. At the moment, the first spraying rods spray the chemical control agent downwards and spray the chemical control agent on the upper surface of the uppermost leaf, the second spraying rods spray the chemical control agent upwards and spray the chemical control agent on the lower surface of the uppermost leaf, and the leaf in the middle of the corn plant is inserted between the adjacent second spraying rods. Because the maize leaf is flexible, consequently can get into between two adjacent second spray bars by oneself after the maize leaf touches the second spray bar, the second spray bar sprays chemical control agent this moment and sprays at the upper surface and the lower surface of blade. The third spray rod sprays chemical control agent and sprays on the lower surface of the blade at the bottom, and the second spray rod sprays chemical control agent and sprays on the upper surface of the blade at the bottom. The hose is provided with a valve to control the liquid pressure in the first, second and third spray bars, and the liquid pressure in the second spray bar is the smallest, and the liquid pressure in the first and third spray bars may be equal or different. Thus realizing double-sided pesticide spraying on leaf surfaces of corn plants.

As shown in fig. 7, in order to facilitate storage, the first to third spray bars can be folded, and include a fixing bar 34 and a folding bar 35, wherein the folding bar is hinged to the fixing bar through a hinge shaft 36, and a damping member is further disposed between the fixing bar and the folding bar to maintain a fixed posture therebetween, such as a right angle included angle therebetween, a collinear line therebetween, and an acute angle therebetween. At this time, the first to third spray bars are still hollow structures, but spray pipes connected with hoses need to be arranged in the first to third spray bars, and the spray pipes are connected with spray heads so as to adapt to the folding of the first to third spray bars.
