Abstract
Description
Technical Field
[0001] This utility model belongs to the field of spraying machine technology, specifically a spraying machine with adjustable spraying range. Background Technology
[0002] A sprayer is an agricultural machine that sprays liquid pesticides and other agents onto crops, soil, or other target areas. Compared with traditional manual spraying, sprayers can complete large-area spraying operations in a short time. With the development of agricultural modernization and the continuous expansion of farmland, manual spraying can no longer meet the needs of large-scale planting. The emergence of sprayers has made pest and disease control and fertilization operations in large-scale farmland more efficient and convenient.
[0003] Utility model patent application publication number 201820001665.8 discloses a sprayer, relating to the field of garden machinery technology, which solves the problem of uneven mixing of pesticide solution. It includes a frame with wheels mounted at the bottom. A drive device for driving the wheels is located on the side of the frame away from the wheels. A storage tank is mounted on the side of the frame away from the wheels. The storage tank has an injection port and a lid covering the injection port. A suction pipe for connecting a spray gun is installed on the storage tank. A circulation device for uniformly mixing the pesticide solution is also installed on the storage tank. The circulation device includes an inlet pipe, a circulation pump, and an outlet pipe connected in sequence to form a circulation loop. The inlet pipe extends into the storage tank and is located at the bottom, while the outlet pipe is located at the top and extends into the storage tank. By setting up the circulation device, the pesticide solution is circulated, promoting the dissolution of powdered pesticides or uniformly mixing liquid pesticides with water, thus reducing the operator's labor intensity.
[0004] As can be seen from the above patent, there is a sprayer with an adjustable spray range, but it still has shortcomings in actual use. The most obvious one is that current sprayers generally use flat nozzles for spraying, and the angle of the flat nozzle is usually fixed, resulting in a limited coverage area. It can usually only spray the area within a specific angle and distance directly in front of the nozzle, which reduces the spray range of the sprayer. Therefore, we propose a sprayer with an adjustable spray range. Utility Model Content
[0005] The purpose of this invention is to provide a sprayer with an adjustable spraying range to solve the problems mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In the scheme of this application:
[0016] 1. By driving the rotating disk to rotate, the rotating disk drives the drive rod at the eccentric position to rotate. Since the drive rod is slidably set in the groove on the connecting rod, when the rotating disk rotates, it can drive the connecting rod to move horizontally back and forth through the drive rod. The connecting rod drives the toothed plates at both ends to slide horizontally. The toothed plates drive the gears and rotating shaft to rotate back and forth. The rotating shaft drives the rotating plate and the fixed frame to rotate. The fixed frame drives the rotating rod and the flat nozzle to swing back and forth, thereby increasing the spraying range of the sprayer.
[0017] 2. By installing a worm gear inside the protective frame, the worm gear meshes with a worm wheel at one end of the rotating rod, so that when the worm gear rotates, it can drive the worm wheel and the rotating rod to rotate. The rotating rod drives the flat nozzle to rotate, which can adjust the tilt angle of the flat nozzle, thereby adjusting the spraying range of the medicine machine. Attached Figure Description
