Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, and more particularly to a medicine spraying device for preventing pear trees from freezing when they are in bloom. Background Art

[0002] Pear tree is a perennial deciduous fruit tree of the genus Pyrus in the Rosaceae family. It is a tree that is widely distributed around the world. The fruit of the pear tree is edible and has high nutritional and medicinal value. During the flowering period, the pear tree needs to be sprayed with antifreeze solution, so a spraying device is needed.

[0003] However, at present, most people inject water and an appropriate amount of the required antifreeze agent into other containers in advance, then mix them evenly, and finally put them into the spraying device for spraying; or directly put the water and the agent into the liquid storage tank of the spraying device, shake the box or directly spray. During this period, it is impossible to fully mix the water and the agent in the spraying device, which reduces the work efficiency of the personnel. At the same time, the operation steps are relatively cumbersome. For this reason, this scheme proposes a drug spraying device for antifreeze of pear tree blossoms. Utility Model Content

[0028] Example:

[0029] See also Figure 1-3 A device for spraying a medicine for preventing pear trees from freezing during flowering comprises a liquid storage tank 1, a cover plate 2 being installed on the upper end of the liquid storage tank 1, a mixing assembly 4 being installed inside the liquid storage tank 1, one end of the mixing assembly 4 passing through the center end of the top side of the cover plate 2, two symmetrically distributed quantitative assemblies 3 being installed on the upper end of the cover plate 2, a water pipe 5 being installed on the right end of the liquid storage tank 1, a spraying rod 6 being installed on the other end of the water pipe 5, and a shoulder strap 7 being provided between the side end of the liquid storage tank 1 and the cover plate 2.

[0030] More specifically, a pressure valve is movably installed at the left end of the liquid storage tank 1 , a pressure pump is installed at the inner bottom end of the liquid storage tank 1 , and one end of the pressure pump is connected to the water pipe 5 .

[0031] During use of this solution, in order to enable personnel to spray antifreeze agents on pear trees in the existing method, they can first release the multiple antifreeze agents required for spraying in two quantitative components 3 into the liquid storage tank 1 in a quantitative manner, and then the personnel can repeatedly pull the mixing component 4 up and down to promote the sufficient mixing and stirring of the released agents inside the liquid storage tank 1, so as to promote the subsequent spraying of the agents to be more effective. At the same time, it eliminates the need for personnel to mix and stir the agents in other containers in advance and quantify them before adding them into the liquid storage tank 1 for spraying, thereby greatly improving the work efficiency of personnel and reducing their labor burden. Subsequently, the personnel only need to carry the liquid storage tank 1 as a whole under the action of the shoulder strap 7, and at the same time, press the pressure valve of the liquid storage tank 1 up and down with the left hand to increase the pressure in the tank, and hold the spray rod 6 with the right hand to spray the pear tree crops. When spraying, keep the nozzle 0.5-1 meter away from the top of the crop, adjust the walking speed according to the wind speed and the amount of liquid, and thus complete the antifreeze agent spraying operation on the pear trees.

[0032] See also Figure 1-3 The quantitative component 3 includes two positioning sleeves 31 fixedly connected to the upper end of the cover plate 2. The upper end of the cover plate 2 is provided with two groups of symmetrically distributed seepage holes 32. There are two groups of seepage holes 32 in each group, and they are located between the inner walls of the positioning sleeves 31. A quantitative cylinder 33 is movably connected between the inner walls of the positioning sleeves 31.

[0033] More specifically, the metering cylinder 33 includes a cylinder 331 movably connected between the inner walls of the positioning sleeve 31, the upper end of the cylinder 331 is threadedly connected to a sealing cover 332, and two symmetrically distributed sealing plates 333 are fixedly connected to the inner bottom wall of the cylinder 331. The sealing plates 333 are located on the upper side of the seepage hole 32, and the outer end of the cylinder 331 is provided with a scale mark 334.

[0034] During the use of this solution, the personnel can first inject an appropriate amount of water into the liquid storage tank 1, and then cover and install the cover plate 2. Later, when adding the medicine, the personnel only needs to distribute two or more medicines into the cylinder 331. At this time, the personnel need to rotate the cylinder 331 to prompt the blocking plate 333 to be located above the seepage hole 32 to block it and prevent the direct flow of the medicine. After the cylinder 331 is filled with medicine, the personnel rotate the cylinder 331 to prompt the seepage hole 32 to open and close. The personnel can observe the decreasing liquid level of the medicine liquid inside the cylinder 331 and compare it with the scale mark 334. After reaching the appropriate dosage, the personnel rotate the cylinder 331 to prompt the blocking plate 333 to block the leakage hole 32, so that the medicine cannot continue to leak, and the quantitative dosage of the medicine is completed to ensure the accuracy of the antifreeze liquid dosage. Finally, after the mixed antifreeze liquid is sprayed, the personnel inject water into the liquid storage tank 1 and add medicine again according to the above steps to mix the antifreeze liquid.

[0035] In this embodiment, the contact surface of the cylinder 331 and the positioning sleeve 31 is a rough surface, which has a large friction force, thereby forming a torsion shaft structure, preventing the cylinder 331 from moving freely on the inner wall of the positioning sleeve 31, and ensuring the sealing performance of the sealing plate 333.

[0036] See also Figure 1-2 The mixing assembly 4 includes a through hole 41 opened at the center end of the upper side of the cover plate 2, and a connecting rod 42 is inserted between the inner walls of the through hole 41. The lower end of the connecting rod 42 is fixedly connected to a positioning seat 43, and the outer end of the positioning seat 43 is installed with a bearing sleeve 44. The lower end of the bearing sleeve 44 is movably connected to a sleeve 45, and the side end of the sleeve 45 is fixedly connected to a plurality of stirring rods 46. The center end of the inner bottom side of the liquid storage tank 1 is fixedly connected to a screw rod 47, which is movably connected to the sleeve 45, and the upper end of the connecting rod 42 is fixedly connected to an armrest 48.

[0037] In this embodiment, the outer diameter of the screw 47 matches the inner diameter of the sleeve 45, and the diameter of the stirring rod 46 is smaller than the distance between the sleeve 45 and the inner wall of the liquid storage tank 1. The sleeve 45 and the stirring rod 46 act as a quick and uniform mixing between the liquids, and the screw 47 acts as the sleeve 45 and the rotating stirring rod 46. The inner diameter of the bearing sleeve 44 matches the outer diameter of the positioning seat 43, and the sleeve 45 is rotatably connected to the screw 47 through the bearing sleeve 44.

[0038] During use, after the water and the medicine are put into the liquid storage tank 1, the personnel pulls the handrail 48 to cause the connecting rod 42 to move up and down, wherein the sleeve 45 forms self-rotation when moving up and down the outer wall of the screw rod 47 through the transmission operation of the bearing sleeve 44, and at the same time drives the stirring rod 46 to rotate to achieve rapid and uniform mixing of the medicine liquid. When the medicine liquid is mixed, the personnel restores the handrail 48 to its initial state and fits it with the top surface of the cover plate 2 for storage, which is convenient for the overall use of the personnel.

[0039] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
