DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The present invention will be further described in detail with reference to the accompanying drawings.

[0024] See also Figure 1 - Figure 6 The oat grass pest control sprayer provided by the utility model includes a medicine barrel 1 with universal wheels at the four corners of the bottom, a handle fixedly connected to the side wall of the medicine barrel 1, support seats 3 installed at intervals on the top of the medicine barrel 1 away from the handle, a steering wheel 2 rotatably connected to the adjacent areas of the two groups of support seats 3, a spray rod 4 installed on the outside of the steering wheel 2, and a spray head 5 installed on the top of the spray rod 4.

[0025] Among them, see Figures 1 to 3The support seat 3 includes a support plate 34 fixedly connected to the top of the medicine barrel 1, and a fixed shaft 31 is fixedly connected to the top of the support plate 34. The adjacent sides of the two groups of fixed shafts 31 are fixedly connected with the mounting shaft 32, and the lower end face of the mounting shaft 32 is fixedly connected to the limit rod 33. The steering wheel 2 includes two symmetrically arranged groups of adjusting disk bodies 21. The adjacent sides of the two groups of adjusting disk bodies 21 are fixedly connected by a connecting shaft. The two groups of adjusting disk bodies 21 are each provided with a placement groove 22 on the side facing away from each other. Several groups of wedge blocks 23 are installed at circumferential intervals in the placement groove 22. The position of the wedge block 23 corresponds to the height of the lower end of the limit rod 33. The mounting shaft 32 passes through the adjusting disk body 21 and is rotatably connected to the adjusting disk body 21.

[0026] It should be noted that a slope is provided on the top of the wedge block 23, and a avoidance groove is provided at the bottom of the inner cavity of the placement groove 22. A spring is fixedly connected to the lower end of the wedge block 23 and the adjacent area of ​​the avoidance groove. When the wedge block 23 is subjected to pressure perpendicular to the axis of the placement groove 22 by the slope, the wedge block 23 compresses the spring and moves to the inside of the receiving groove. After the pressure disappears, the spring pushes the wedge block 23 to move the upper end of the wedge block 23 out of the receiving groove.

[0027] It should be added that a water pump is provided in the medicine barrel 1, which pumps out the medicine in the medicine barrel 1. A hose is provided on the side wall of the medicine barrel 1, one end of the hose is connected to the water outlet end of the water pump, and the other end of the hose is connected to the spray rod 4 fixedly connected to the connecting shaft.

[0028] It can be understood that the water pump pumps out the medicine, which is transported to the spray rod 4 through the hose, and then transported to the nozzle 5 through the spray rod 4 for spraying. The inclination angle of the spray rod 4 can be controlled by rotating the adjustment disk 21. At the same time, the lower end of the limit rod 33 pushes the wedge block 23 to compress the spring and store it in the avoidance groove. After the adjustment is completed, the wedge block 23 pushed out of the avoidance groove by the spring is limited by the lower end of the limit rod 33, preventing the adjustment disk 21 from rotating in the direction, causing the spray rod 4 with the adjusted inclination angle to rotate.

[0029] See also Figure 4 and Figure 5The nozzle 5 includes a nozzle shell 51 and an adjusting disk 52. The nozzle shell 51 includes a sealing shell 512 fixedly connected to the spray rod 4. The sealing shell 512 is fixedly connected to the inner cavity of the end away from the spray rod 4 with a sealing column 513. The outer wall of the sealing shell 512 away from the spray rod 4 is provided with a plurality of groups of spray holes 511 at intervals. The adjusting disk 52 includes a disk body 521 slidably connected to the inner wall of the sealing shell 512. The disk body 521 is provided with a water outlet hole 522 in the middle part of the side near the spray hole 511. The upper end surface of the water outlet hole 522 is coaxially provided with an elastic component 523. The two ends of the elastic component 523 are respectively fixedly connected to the upper end surface of the disk body 521 and the top of the inner cavity of the sealing shell 512. The disk body 521 is fixedly connected to a plurality of groups of micro water spray columns 525 at intervals near the spray hole 511. The top of the micro water spray column 525 is provided with a plurality of groups of micro spray holes 524 at intervals.

[0030] It should be added that the water outlet 522 is coaxially arranged with the sealing column 513, and the outer diameter of the water outlet hole 522 is equal to the inner diameter of the sealing column 513, several groups of micro water spray columns 525 and several groups of spray holes 511 are respectively located on the same axis, and the outer diameter of the micro water spray columns 525 is equal to the inner diameter of the spray hole 511.

[0031] It can be understood that the medicine is pumped into the sealed shell 512 through the spray rod 4 by the water pump, passes through the water outlet 522 and is sprayed out through several groups of spray holes 511 to spray the oat grass. When it is necessary to adjust the water mist type, the water pump power is increased to increase the water pressure of the medicine entering the sealed shell 512. The increased water pressure pushes the disc 521 toward the top of the sealed shell 512 until the sealing column 513 extends into the water outlet 522 and closes the water outlet 522. At the same time, several groups of micro water spray columns 525 extend into the spray holes 511 respectively. The medicine in the sealed shell 512 passes through the micro water spray columns 525 and then passes through several groups of micro spray holes 524 for further atomization, thereby reducing the particle size of the atomized water droplets and achieving the purpose of adjusting the water mist type.

[0032] Principle: Rotate the adjustment disc 21 to adjust the inclination angle of the spray rod 4. During the adjustment, the lower end of the limit rod 33 moves along the inclined surface of the wedge block 23, pushing the wedge block 23 to compress the spring and move into the avoidance groove. After the adjustment is completed, the wedge block 23 pushed out by the spring limits the lower end of the limit rod 33, thereby locking the adjustment disc 21 to prevent the inclination angle of the spray rod 4 from deflecting after the adjustment. Start the water pump, and the medicine will be diverted into the sealed shell 512 through the spray rod 4, and dispersed through the water outlet 522 and the spray hole 511 to the swallow. When spraying wheat straw and needing to reduce the spraying particle size, the horsepower of the water pump is increased to increase the water pressure entering the sealed shell 512. The water pressure pushes the disc 521 to compress the elastic component 523 toward the top of the sealed shell 512, and the sealing column 513 moves into the water outlet 522 to seal the water outlet 522. Several groups of micro water spray columns 525 move into the spray hole 511 respectively. After the medicine is diverted by the micro water spray columns 525, it is further refined through the micro spray holes 524, thereby greatly reducing the water mist particle size and realizing the change of spray type.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
