Description

Technical Field

[0001] The utility model belongs to the technical field of crop pest control equipment, in particular to a crop pest spraying device. Background Art

[0002] Pest control by spraying pesticides is an artificial means of reducing or preventing pathogenic microorganisms and pests from harming crops or humans and livestock. It can generally be divided into chemical control using chemical substances such as pesticides and physical control using physical energy such as light or rays or building barriers.

[0003] Some crops grown on small areas require manual spraying to eliminate pests, and conventional sprayers require the arms to be raised to spray most crops. When the arms are raised high, the arms themselves bear a relatively large weight, and the shoulders and arms are prone to soreness, which causes fatigue during the operation of conventional sprayers.

[0004] For this reason, we propose a crop disease and insect pest spraying device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of easy fatigue during the operation of conventional sprayers and proposes a crop pest spraying device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A crop pest spraying device includes a Z-shaped liquid guide tube, the upper portion of which is covered with a Velcro hook, which is attached to a Velcro elastic band. A nozzle is slidably and sealingly mounted on the upper portion of the Z-shaped liquid guide tube. A limited rotation groove is defined at the rear portion of the nozzle, and the interior of the Z-shaped liquid guide tube slides and engages within the limited rotation groove. A threaded button is rotatably mounted on the front portion of the Z-shaped liquid guide tube, and the button is threadedly mounted on the exterior of the nozzle. By tying the Velcro elastic band to the forearm, then grasping the lower portion of the Z-shaped liquid guide tube with the hand, and then attaching the Velcro hook to the exterior of the Velcro elastic band, the Z-shaped liquid guide tube and nozzle are sprayed at a higher height, eliminating the need to lift the arm, and reducing arm labor.

[0008] Preferably, the Z-shaped catheter comprises a first tube body and a guide ring, wherein the guide ring is fixedly connected to the upper portion of the first tube body, and the guide ring facilitates the rotation of the threaded button.

[0009] Preferably, the lower portion of the first tube is covered with a leather case, so as to increase the comfort of gripping the lower portion of the first tube.

[0010] Preferably, the Velcro elastic band includes an elastic band and a Velcro hook surface, and the side of the elastic band facing away from the Velcro hook surface is a Velcro fleece surface. The elastic band is wrapped around the forearm, and the Velcro hook surface is attached to the elastic band, making it convenient to wear the Velcro elastic band on the forearm.

[0011] Preferably, the Velcro hook includes a pattern hook surface and an elastic sleeve, wherein the elastic sleeve is fixedly connected to the outside of the pattern hook surface. The height of the elastic sleeve is adjusted to facilitate the height matching of the pattern hook surface with the Velcro elastic band on the forearm.

[0012] Preferably, the spray pipe includes a second tube body, a nozzle, and a sealing ring. The rear portion of the second tube body defines a limited rotation groove. The sealing ring is fixedly connected to the exterior of the second tube body. The nozzle is fixedly connected to an end of the second tube body facing away from the Z-shaped liquid guide tube. After the liquid medicine enters the second tube body, it is sprayed outward through the nozzle.

[0013] Preferably, the threaded button comprises a rotating knob and a nut, wherein the rotating knob and the nut are fixedly connected as a whole. Rotating the nut drives the nozzle to extend or retract.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. Tie the Velcro elastic band around your forearm, then hold your hand at the bottom of the Z-shaped catheter, and then stick the Velcro hook to the outside of the Velcro elastic band to increase the height of the Z-shaped catheter and nozzle spraying, avoid the operation of lifting your arm, and reduce the labor intensity of your arm.

[0016] 2. Wrap the elastic band around your forearm, and then stick the hook surface of the Velcro on the elastic band to make it easier to wear the Velcro elastic band on your forearm.

[0017] 3. Adjust the height of the elastic sleeve to make the hook surface of the pattern match the height of the Velcro elastic band on the forearm. BRIEF DESCRIPTION OF THE DRAWINGS
