DETAILED DESCRIPTION

[0026] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0027] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0028] The following is a description of the preferred embodiments of the present application in conjunction with the accompanying drawings.

[0029] As Figure 1 shown, the present application provides a garden pesticide spraying machine, which comprises a frame 1, a rotating wheel 11 is installed at the bottom of the frame 1, and the pesticide spraying machine can be moved by the rotating wheel 11. It should be noted that the rotating wheel 11 here can be turned, which belongs to the conventional prior art, and since it is not the key point of the present application, the drawing method is omitted, and will not be described in detail here.

[0030] The middle part of the frame 1 is concave downward, in the shape of "U", a medicament tank 2 is fixedly installed in the concave part of the middle part of the frame 1, and a sprayer 4 which can be driven to rotate up and down and left and right by a driving mechanism is installed at the front end of the frame 1. A water pump 3 is also fixedly installed in the middle part of the frame 1, the water inlet end of the water pump 3 is fixedly connected and communicated with the first hose 31 which is fixedly connected and communicated with the medicament tank 2, and the water outlet end of the water pump 3 is fixedly connected and communicated with the second hose 32 which is fixedly connected and communicated with the sprayer, wherein the length of the second hose 32 is in excess, that is, it will not affect the rotation of the sprayer 4.

[0031] A push handle 12 is fixedly connected to the rear end of the frame 1, and an anti-skid sleeve 13 is fixedly sleeved to the middle of the top of the push handle 12. The anti-skid sleeve 13 is provided with a plurality of transverse anti-skid lines. A user can easily push the device by holding the anti-skid sleeve 13, so that the device reaches the area to be sprayed.

[0032] As shown in Figure 1 , Figure 2 , Figure 3 The structure for driving the nozzle 4 to rotate left and right to adjust the position mainly includes a cylindrical rotating sleeve 47 that can be driven to rotate by the second motor 50, and the rotating sleeve 47 is rotatably installed inside the front end of the frame 1. The rotating sleeve 47 is arranged in the vertical direction, and the top end of the rotating sleeve 47 extends upward and is fixedly connected with the mounting seat 41 through the top wall of the frame 1. The nozzle 4 can rotate synchronously with the rotating sleeve 47.

[0033] There are many ways for the second motor 50 to drive the rotating sleeve 47 to rotate, for example, the output shaft of the second motor 50 is fixedly connected with a first gear, and a second gear is fixedly connected coaxially on the rotating sleeve 47, and the second gear is engaged with the first gear. In this embodiment, a worm gear cooperation mode is adopted. Specifically, the second motor 50 is fixedly installed inside the frame 1, the output shaft of the second motor 50 is fixedly connected coaxially with a first worm 49, and the bottom of the rotating sleeve 47 is fixedly connected coaxially with a first worm gear 48, and the first worm gear 48 is engaged with the first worm 49. Through the transmission mode of the worm gear, the nozzle 4 can also be self-locked when it stops rotating left and right, so that the structure of the device is more stable.

[0034] The main structure for driving the nozzle 4 to rotate up and down to adjust the position includes an installation shaft 42 that can be driven to rotate by the third motor 55, and the front view of the mounting seat 41 is in the shape of “U”. The two ends of the installation shaft 42 are rotatably connected with the two side walls of the mounting seat 41, respectively, and the installation shaft 42 is fixedly installed with an installation rod 43, and the top end of the installation rod 43 is fixedly connected with the nozzle 4.

[0035] The third motor 55 drives the mounting shaft 42 to rotate in many ways, for example, the third motor 55 is directly mounted on the side wall of the mounting seat 41, and the output shaft of the third motor 55 is directly fixedly connected with the mounting shaft 42. Although this driving mode is feasible, the structure is unreliable. In the embodiment, the driving mechanism still adopts the worm and gear mode to drive the nozzle 4 to rotate up and down; specifically, the third motor 55 is fixedly installed in the inner side of the front end of the rack 1, and the output shaft of the third motor 55 is coaxially fixedly connected with the second worm 54. The second worm 52 is rotatably installed on the bottom of the inner side of the rack 1, and the second worm 52 is engaged with the second worm 54. The second worm 52 is coaxially fixedly connected with the rotating shaft 46, and the top of the rotating shaft 46 is coaxially fixedly connected with the second bevel gear 45 through the bottom of the mounting seat 41. The top of the rotating shaft 46 is rotatably connected with the mounting seat 41. The mounting shaft 42 is coaxially fixedly connected with the first bevel gear 44, and the first bevel gear 44 is engaged with the second bevel gear 45. The rotating shaft 46 is rotatably connected with the rotating sleeve 47.

[0036] As shown in Figure 3 , Figure 5 , the rotating shaft 46 and the rotating sleeve 47 are rotatably connected, that is, the side wall of the rotating shaft 46 is provided with a plurality of annular grooves 56, and the inner wall of the rotating sleeve 47 is annularly provided with a plurality of protrusions 57 matched with the grooves 56. The protrusions 57 are located in the grooves 56 and are rotatably connected with the grooves 56.

[0037] Through the cooperation of the protrusions 57 and the grooves 56, the rotating shaft 46 and the rotating sleeve 47 can only rotate relative to each other, and cannot move up and down.

[0038] As a further illustration of the present example, the first worm 48 is located above the second worm 52, and the first worm 48, the second worm 52, the rotating shaft 46, the rotating sleeve 47 and the second bevel gear 45 are coaxial. The second fixed seat 53 is fixedly connected to the bottom of the inner side of the rack 1, and the bottom of the rotating shaft 46 is rotatably connected with the second fixed seat 53 through the second worm 52. The first fixed seat 51 is also fixedly connected to the bottom of the inner side of the rack 1, and the second motor 50 is fixedly installed on the first fixed seat 51.

[0039] As shown in Figure 1 , Figure 4 , the top of the medicament tank 2 is fixedly connected with the first motor 21, the output end of the first motor 21 is fixedly connected with the stirring shaft 25 through the top wall of the medicament tank 2, the bottom end of the stirring shaft 25 is fixedly connected with the stirring fan 26, and the stirring fan 26 is located in the medicament tank 2. The top of the medicament tank 2 is provided with a water inlet 23, and the rear end of the top of the medicament tank 2 is provided with a medicine filling port 22.

[0040] The medicine filling port 22 is separated from the water filling port 23 mainly because the water filling port 23 is generally designed as a small cylinder for connecting a water pipe, and at this time, it is inconvenient to add the medicine, therefore, the two are separated, and the medicine filling port 22 is designed as a separate square opening, which is more convenient for adding the medicine. After the medicine and water are added into the medicine tank 2 in proportion, the rotation of the stirring fan 26 can be driven by starting the first motor 21, so that the two are fully mixed, and after the medicine in the medicine tank 2 is used for a period of time, the first motor 21 can be started again to prevent the medicine in the medicine tank 2 from precipitating or being uneven.

[0041] As a further illustration of the present example, in order to make the installation of the medicine tank 2 more stable, the fixed sleeve 24 is fixedly installed in the recess in the middle of the rack 1, the fixed sleeve 24 is sleeved on the bottom of the medicine tank 2, so that the installation of the medicine tank 2 in the device is more stable, and the stability of the device is further increased.

[0042] As a further illustration of the present example, the second motor 50 and the third motor 55 in the above are motors capable of forward and reverse rotation; the first motor 21, the second motor 50, the third motor 55 and the water pump 3 can be remotely controlled by the controller, and the two functions belong to mature prior art and are not the main points of the present application, and will not be described in detail here.

[0043] The use and principle of the device are as follows: when it is necessary to spray medicine on garden plants, first, water is added to the medicine tank 2 and medicine is added, and the first motor 21 is started, so that the medicine and water are fully mixed, and then the user can push the device to the area to be sprayed to spray the medicine. When reaching the area to be sprayed, the angle of the spray head is adjusted by the second motor 50 and the third motor 55 to spray the medicine. If high trees are encountered, the third motor 55 can be started during the spraying process to spray the trees from top to bottom, so that the spraying process is more comprehensive.

[0044] In summary, the garden medicine spraying machine of the present application drives the rotation of the first worm 49 and the first worm wheel 48 through the second motor 50, so that the mounting seat 41 can rotate left and right along the horizontal direction to adjust the position, so that the user does not need to move the spraying machine as a whole during the garden spraying process, and can spray the plants on both sides of the road, which is more convenient and efficient. The rotation of the second worm 54 and the second worm wheel 52 is driven by the third motor 55, and then the first bevel gear 44 and the second bevel gear 45 are driven, so that the spray head 4 is adjusted up and down along the vertical direction to adjust the spraying angle, so that the coverage of the spraying is wider and more comprehensive, and the applicability of the device is increased. In addition, the transmission mode of the worm wheel and the worm has a self-locking function, so that the device can be more stable during use.

[0045] The above merely is the preferred implementation form of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
