Pesticide sprayer nozzle

Abstract

The utility model discloses a pesticide sprayer nozzle, which relates to the technical field of pesticide and comprises a connecting rod, one end of the connecting rod is connected with a liquid storage box, and the other end of the connecting rod is connected with a handle, so that the two nozzles are driven to slide, and the distance between the two nozzles can be adjusted. The agricultural pesticide spraying device is suitable for spraying pesticides to crops at different intervals, workers do not need to shake the device left and right, and therefore the problems that a lot of pesticides are wasted when an existing device sprays the crops with the large line spacing, and especially when plants and leaves of the crops are small in the early growth stage, pesticide spraying is not needed are solved. A left-right shaking spraying mode can spray a large amount of pesticide on the ground to cause waste of the pesticide, left-right shaking increases the working intensity of operators, however, if the left-right shaking spraying mode is not adopted for spraying the pesticide, a traditional spray head can only spray the pesticide on crops in a single row, the efficiency is low, and the labor intensity is high. And the pesticide spraying speed is severely reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of pesticides, in particular to a pesticide sprayer nozzle. Background Art

[0002] Pesticide sprayers play an extremely important role in agricultural planting, especially shoulder-type manual pesticide sprayers. Farmers can directly carry the sprayer on their backs and then spray the crops. It is simple to operate and easy to use.

[0003] When spraying pesticides with existing pesticide sprayers, operators hold spray rods to spray crops. Because different crops have different plant spacing and row spacing, only reasonable dense planting can increase yield. For example, the row spacing required for corn planting is larger than the row spacing required for wheat planting. When spraying pesticides on some crops with larger row spacing, the traditional spraying method is to use operators to hold the spray rod and swing it left and right to spray the crops. However, this method will waste a lot of pesticides for spraying crops with larger row spacing, especially for crops in the early growth stage when the plants and leaves are small. The left-right swinging spraying method will spray a large amount of pesticides on the ground, resulting in a waste of pesticides, and the left-right swinging increases the work intensity of the operators. However, if the left-right swinging method is not used to spray pesticides, the traditional nozzle can only spray pesticides on a single row of crops, which is inefficient and seriously reduces the speed of pesticide spraying. For this reason, we propose a pesticide sprayer nozzle. Utility Model Content

Spraying pesticides, the two sliding plates 3 slide on the inner side of the through groove 4, thereby driving the two connecting heads 5 to slide, and then driving the two nozzles 6 to slide, so that the distance between the two nozzles 6 can be adjusted, so as to adapt to spraying pesticides on crops with different spacings. There is no need for workers to shake the device left and right to spray pesticides on the crops, which wastes physical strength and pesticides. This solves the problem that the existing device will waste a lot of pesticides when spraying crops with a large row spacing, especially when the plants and leaves are small in the early stage of crop growth, the left and right shaking spraying method will spray a large amount of pesticides on the ground, resulting in a waste of pesticides, and the left and right shaking increases the work intensity of the operators. However, if the left and right shaking method is not used to spray pesticides, the traditional nozzles can only spray pesticides on a single row of crops, which is inefficient and seriously reduces the speed of pesticide spraying.

[0023] like Figure 1 , Figure 2 As shown, in some embodiments, two symmetrically distributed grooves 21 are provided on the inner side of the through slot 4, and two symmetrically distributed L-shaped blocks 17 are connected to the sliding plate 3, and the end of the L-shaped block 17 away from the sliding plate 3 is slidably connected to the inner side of the groove 21, and a spring 20 is also connected to the inner side of the groove 21, and the end of the spring 20 close to the L-shaped block 17 is connected to the L-shaped block 17, and the sliding plate 3 slides on the inner side of the through slot 4, thereby causing the L-shaped block 17 to slide on the inner side of the groove 21, thereby stretching the spring 20, and under the action of the spring 20, the L-shaped block 17 can be driven to slide in the opposite direction on the inner side of the groove 21, thereby driving the sliding plate 3 to slide in the opposite direction on the inner side of the through slot 4, thereby causing the sliding plate 3 to slide left and right on the inner side of the through slot 4.

[0024] like Figure 1 , Figure 2As shown, in some embodiments, the liquid storage box 2 is rotatably connected to two symmetrically distributed rotating shafts 7 between the two connecting heads 5, the connecting rod 1 is slidably connected to a T-shaped slider 11, the T-shaped slider 11 is connected to a fixed column 10, a pull rope 8 is connected between the two connecting heads 5, the outer side of the pull rope 8 passes around the two rotating shafts 7, and the closed end of the pull rope 8 is sleeved on the fixed column 10, the T-shaped slider 11 slides on the connecting rod 1, thereby driving the fixed column 10 to slide, and then stretching the pull rope 8. Under the action of the two rotating shafts 7, the pull rope 8 plays a guiding role when moving, thereby pulling the two connecting heads 5 to slide relative to each other, thereby driving the two sliding plates 3 to slide relative to each other on the inner sides of the two through grooves 4, and then stretching the spring 20. When the spring 20 releases energy, it drives the two sliding plates 3 to slide away from each other on the inner sides of the two through grooves 4, thereby being able to adjust the distance between the two nozzles 6.

The screw 12 is threadedly connected to the inner side of the thread groove 16 at one end close to the T-shaped groove 9. The T-shaped slider 11 slides on the inner side of the T-shaped groove 9, thereby causing the two nozzles 6 to slide relative to or away from each other. The screw 12 is threadedly connected to the inner side of the thread groove 16, thereby limiting the T-shaped slider 11 and adjusting the distance between the two nozzles 6.

[0026] like Figure 3 , Figure 4 As shown, in some embodiments, a partition 15 is connected to the inner side of the liquid storage box 2, and the partition 15 divides the inner side of the liquid storage box 2 into a first chamber 18 and a second chamber 19.

The clamping rings are used to limit the pull rope 8 to prevent the pull rope 8 from slipping off the fixed column 10 and the rotating shaft 7.

[0028] like Figure 1-Figure 4 As shown, in some embodiments, the handle 13 is provided with anti-skid patterns, which can play an anti-skid role.
