Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device for branch wounds in the rescue of ancient trees. Background Technology

[0002] Ancient trees, generally referring to trees over a hundred years old, are "living relics" of nature and human history, carrying unique ecological value, cultural memory, and scientific research significance. Having weathered countless storms, their trunks are thick and mottled, their branches gnarled and vigorous. While possessing strong vitality and resilience, their cellular activity decreases and metabolic functions decline with age, making their self-repair capabilities far less than those of younger plants. Any minor damage to a branch can become a threat to their survival. In the field of ancient tree rescue, effective treatment of branch wounds is a crucial step in preventing pest and disease infestations and promoting healing.

[0003] A search revealed a fruit tree sprayer with publication number CN220557259U, comprising a mobile trolley, a pesticide tank mounted on the trolley, a detachable top cover mounted on the pesticide tank, a rotating sleeve vertically rotatable on the trolley, a connecting hose fixedly connected between the rotating sleeve and the pesticide tank, a connecting bend fixedly mounted on the upper end of the rotating sleeve, a spray head slidably mounted on the free end of the connecting bend, multiple sets of stirring rods fixedly mounted on the outer circumference of the rotating rod, and a transmission mechanism between the top cover and the rotating sleeve. The retractable column drives the spray heads forward via a slider, distributing them between two trees. The left-right swinging spray heads then spray the gaps between the fruit trees, achieving convenient spraying between adjacent trees and improving the comprehensiveness of fruit tree spraying.

[0004] When using the device disclosed in this patent, the random spraying of large quantities of medicine can easily increase the cost of rescuing ancient trees. Furthermore, since ancient trees are usually tall and their branches are located high up, relying on manual climbing and handheld spraying equipment to spray medicine is not only inefficient, but may also damage the bark or branches of ancient trees due to external force. Utility Model Content

[0005] In response to the problems in existing patents, such as the increased cost of rescuing ancient trees due to the large amount of random spraying of medicine, and the inefficiency and potential damage to the bark or branches of ancient trees caused by manual climbing and handheld spraying equipment due to their height and high branches, this utility model provides a branch wound spraying device for ancient tree rescue.

[0006] The technical solution adopted in this utility model is: a spraying device for treating branch wounds in the rescue of ancient trees, comprising:

[0007] Flatbed cart, the flatbed cart being equipped with a drug supply mechanism on its upper side;

[0008] The spraying mechanism includes a base fixed to the upper side of the flatbed cart, a U-shaped seat rotatably fitted to the upper side of the base, a rotating shaft fixed inside the U-shaped seat, two positioning discs fixedly sleeved on the rotating shaft, a U-shaped operating handle rotatably fitted to the rotating shaft, a U-shaped limiting handle elastically slidingly fitted to the U-shaped operating handle, multiple positioning grooves circumferentially arrayed on the side of the positioning discs, a spray gun fixed inside the U-shaped operating handle, and a laser sight mounted on the spray gun. The U-shaped limiting handle corresponds to the positioning grooves, and the drug supply mechanism is connected to the spray gun.

[0009] Furthermore, bearings are embedded on both sides of the U-shaped operating handle, and the bearings are fixedly sleeved on the rotating shaft.

[0010] Furthermore, the U-shaped operating handle is provided with guide channels on both sides, and the U-shaped limiting handle is slidably engaged in the two guide channels. The guide channels are provided with guide slides on their inner sides, and the U-shaped limiting handle is provided with guide protrusions on its side corresponding to the guide slides. The guide protrusions are slidably engaged in the guide protrusions.

[0011] Furthermore, a spring damper is provided inside the guide slide, and the spring damper is fixedly connected to the U-shaped limit handle.

[0012] Furthermore, a spring ball is embedded at the bottom of the U-shaped base, and multiple limiting grooves are arranged in a circular array on the upper side of the base, with the spring ball corresponding to the limiting groove.

[0013] Furthermore, the drug supply mechanism includes a drug tank fixed on the upper side of the flatbed cart, a feed valve connected to the upper side of the drug tank, a high-pressure metering pump connected to the side of the drug tank, and a connecting pipe connected between the high-pressure metering pump and the spray gun.

[0014] The beneficial effects of this utility model are:

[0015] By setting a U-shaped operating handle to drive the spray gun and laser sight to rotate vertically and horizontally for positioning, it is easy to control the horizontal and vertical orientation of the spray gun through the U-shaped operating handle, which improves the convenience of adjusting the spray gun orientation.

[0016] By setting up a laser sight and a high-pressure metering pump, the spray gun, in conjunction with the laser sight, can accurately spray the medicine at the location of the branch wound. The high-pressure metering pump can also spray a fixed amount of medicine at the location of the branch wound, which facilitates precise spraying and avoids excessive scattering that increases spraying costs. Climbing trees to high places affects spraying, which is not only inefficient but also easily damages ancient trees. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0026] To address the problems existing in the background art, this application proposes the following technical solution:

[0027] A spraying device for treating branch wounds in ancient tree rescue, comprising:

[0028] Flatbed cart 1, with a medicine supply mechanism 2 installed on the upper side of flatbed cart 1;

[0029] The spraying mechanism 3 includes a base 300 fixed on the upper side of the flatbed trolley 1, a U-shaped seat 301 rotatably fitted on the upper side of the base 300, a rotating shaft 302 fixed inside the U-shaped seat 301, two positioning discs 303 fixedly fitted on the rotating shaft 302, a U-shaped operating handle 304 rotatably fitted on the rotating shaft 302, a U-shaped limiting handle 305 elastically slidably fitted on the U-shaped operating handle 304, a plurality of positioning grooves 306 circumferentially arrayed on the side of the positioning discs 303, a spray gun 307 fixed inside the U-shaped operating handle 304, and a laser sight 308 provided on the spray gun 307. The U-shaped limiting handle 305 corresponds to the positioning grooves 306, and the drug supply mechanism 2 is connected to the spray gun 307.

[0030] Furthermore, bearings 309 are embedded on both sides of the U-shaped operating handle 304. The bearings 309 are fixedly sleeved on the rotating shaft 302, which helps to improve the stability of the U-shaped operating handle 304 rotating on the rotating shaft 302.

[0031] Furthermore, the U-shaped operating handle 304 has guide channels 310 on both sides, and the U-shaped limiting handle 305 is slidably engaged in the two guide channels 310. The guide channels 310 are provided with guide slides 311 on their inner sides. The U-shaped limiting handle 305 has guide protrusions 312 on its side corresponding to the guide slides 311. The guide protrusions 312 are slidably engaged in the guide protrusions 312. The guide slides 311 are provided with spring dampers 313. The spring dampers 313 are fixedly connected to the U-shaped limiting handle 305, which facilitates the improvement of the stability of the U-shaped limiting handle 305 sliding on the U-shaped operating handle 304.

[0032] Furthermore, a spring ball 314 is embedded at the bottom of the U-shaped seat 301, and multiple limiting grooves 315 are arranged in a circular array on the upper side of the base 300. The spring ball 314 corresponds to the limiting grooves 315, which facilitates automatic positioning of the position of the U-shaped seat 301 after rotation.

[0033] Furthermore, the drug supply mechanism 2 includes a drug tank 201 fixed on the upper side of the flatbed trolley 1, a feed valve 202 connected to the upper side of the drug tank 201, a high-pressure metering pump 203 connected to the side of the drug tank 201, and a connecting pipe 204 connected between the high-pressure metering pump 203 and the spray gun 307.

[0034] Working principle: Move the device to the side of the ancient tree, turn on the laser sight 308, and rotate the U-shaped base 301, spray gun 307, and laser sight 308 horizontally via the U-shaped operating handle 304. Adjust the horizontal orientation of the spray gun 307 and laser sight 308. The spring ball 314 engages with the limiting groove 315, positioning the U-shaped base 301 and thus the horizontal orientation of the spray gun 307. Pull the U-shaped limiting handle 305 in the U-shaped operating handle 304 to slide out of the positioning groove 306, causing the spray gun 307 and laser sight 308 to rotate vertically via the U-shaped operating handle 304. Release the U-shaped limiting handle 305, and through the spring damper 313, move the U-shaped limiting handle 305 into the positioning groove 306, positioning the spray gun 307 and laser sight 308. The vertically rotated position of the aiming device 308 facilitates the control of the horizontal and vertical orientation of the spray gun 307 via the U-shaped operating handle 304, improving the convenience of adjusting the spray gun 307. Combined with the laser aiming device 308, it allows for precise spraying of the pesticide at the branch wound location. The high-pressure metering pump 203 sprays a metered amount of pesticide onto the branch wound, ensuring precise and quantitative pesticide application and avoiding excessive scattering that increases spraying costs. The problem of climbing trees affecting spraying is not only inefficient but also prone to damaging ancient trees. By setting the horizontal and vertical adjustment positions of the spray gun 307, it is easier to reduce the vertical rotation of the spray gun 307 when adjusting the horizontal rotation, and to improve the efficiency of the horizontal rotation of the spray gun 307 when adjusting the vertical rotation, thus improving the adjustment efficiency of the spray gun 307.
