Description

Technical Field

[0001] The utility model belongs to the technical field of gardening and greening, and more specifically, particularly relates to a maintenance device. Background Art

[0002] In the garden landscape, lush plant communities form a harmonious picture of nature and beauty. In order to ensure the vigor and health of these plants, pesticides, nutrient solutions and other solutions need to be sprayed for maintenance at fixed times each year. Manual sprayers are low-cost and high-efficiency, and are commonly used solution spraying tools for garden maintenance personnel. Existing manual sprayers are generally composed of a sprayer body, a carrying strap, a pressure rod, a spray tube and other components.

[0003] Existing application number: CN202122944237.3, the utility model discloses a manual reciprocating sprayer, including a sprayer body, the bottom of the sprayer body is connected to a spray rod through a transmission water pipe, a pressure cylinder is installed on the side of the sprayer body away from the spray rod, a hand-cranked air rod is connected to the pressure cylinder, a hand crank is rotatably connected to the side of the sprayer body close to the pressure cylinder, an end of the hand cranked air rod away from the pressure cylinder is rotatably connected to the hand crank, an adjustment groove is provided on the end of the hand cranked air rod close to the hand crank, and a movable sleeve is provided on the end of the hand cranked air rod close to the adjustment groove. This kind of manual reciprocating sprayer can adjust the length of the pressure cylinder and the hand cranked air rod by arranging an adjustable length hand cranked air rod on the sprayer body, so as to facilitate the use of people of different body shapes, and to facilitate the adjustment of the lifting height of the hand cranked air rod and the amplitude of manual reciprocation according to personal usage habits.

[0004] Based on the above, although manual sprayers are low-cost and affordable, they not only require frequent pressing of the pressure lever during operation, but also require carrying and moving, which is quite laborious. In addition, the capacity of the sprayer is relatively limited. When spraying solutions for maintenance operations in some larger gardens, workers need to go back and forth to the water collection point many times. This process is not only time-consuming and labor-intensive, but also reduces overall work efficiency. Utility Model Content

[0060] A water tank 4, which is fixedly connected to the chassis 1;

[0061] A placement box 5 is fixedly connected to the chassis 1;

[0062] Push the handle 6, which is fixedly connected to the right side of the chassis 1;

[0063] A fixed bin 12, the fixed bin 12 is fixedly connected to the front of the chassis 1;

[0064] A fixing member 15, the bottom of which is rotatably connected to the top of the placement box 5;

[0065] A fixing groove 1501, the fixing groove 1501 is provided inside the fixing member 15;

[0066] The driven operating component is arranged inside the chassis 1 .

[0067] Among them, the slave operation components include:

[0068] A driving pulley 7, which is coaxially fixedly connected to the outer side of the roller 101 on the right side;

[0069] A connecting shaft 8, wherein the connecting shaft 8 is rotatably connected to the inside of the chassis 1;

[0070] A driven pulley 801, which is coaxially fixedly connected to the rear end of the connecting shaft 8;

[0071] The transmission belt 9 is connected to the outside of the driving pulley 7 and the driven pulley 801. The function of the transmission belt 9 is to push the handle 6 to push the chassis 1 to move left and right, and the roller 101 and the roller 2 to rotate, and the connecting shaft 8 can be driven to rotate through the transmission mechanism composed of the driving pulley 7, the driven pulley 801 and the transmission belt 9.

[0072] The slave operation component also includes:

[0073] A transmission turntable 802, which is coaxially fixedly connected to the front end of the connecting shaft 8;

[0074] The first connecting column 10 is fixedly connected in front of the transmission turntable 802, so that the connecting shaft 8 drives the first connecting column 10 to make a circular motion with the connecting shaft 8 as the axis through the transmission turntable 802.

[0075] The slave operation component also includes:

[0076] A connecting member 11, the bottom of the connecting member 11 is hingedly connected to the outside of the first connecting column 10;

[0077] The second connecting column 1101 is fixedly connected to the top of the connecting piece 11. The second connecting column 1101 is arranged inside the right end of the operating pressure rod 301. The effect brought about is that the second connecting column 1101 is both slidably connected and rotatably connected to the right end of the operating pressure rod 301 through its own cylindrical structure. The first connecting column 10 drives the operating pressure rod 301 to reciprocate through the connecting piece 11 and the second connecting column 1101, so that the end of the spray tube 302 can spray medicines and other solutions outward.

[0078] The specific usage and function of this embodiment are as follows:
