[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. It is one of the important components of the national economy. Forestry is engaged in the cultivation, protection and utilization of forest resources between humans and the biosphere through advanced science and technology and management methods, fully utilizing the multiple benefits of forests, and can sustainably manage forest resources to promote the coordinated development of population, economy, society, environment and resources.

[0031] Working principle: When the present invention is used, Figure 7As shown, first, the device is fixed on the side wall of the waterwheel through the mounting seat 1, and the mounting seat 1 can be fixed on the side wall of the waterwheel by bolts, and then the slide bar 20 is pulled through the third connecting plate 43. At this time, the two push-pull rods 11 and the guide rod 31 are pulled at the same time, and the first spring 29 and the third spring 33 are compressed by force. When the spiral part of the guide slide groove 23 on the slide bar 20 passes through the guide slide groove 23, the third connecting plate 43 is stopped. When the spiral part of the guide slide groove 23 passes through the guide slide groove 23, the slide bar 20 rotates 180° in the clockwise direction under the limiting action of the ball 22, and the roller 39 rotates synchronously with the slide bar 20. At this time, the first L-shaped connecting rod 20 is connected through the water pipe. The port of the pipe 13 is connected to the water outlet of the water tank of the waterwheel, and then the third connecting plate 43 is loosened. At this time, under the action of the first spring 29 and the third spring 33 and the water pressure in the water tank of the waterwheel, the slide bar 20 is quickly reset. During the reset process, the piston 10 sucks the water in the water tank of the waterwheel into the cylinder 7 through the first L-shaped connecting pipe 13 for storage. At this time, the waterwheel can slowly move along a row of planted trees (such as thick trees on both sides of the road). During the movement of the waterwheel, the slide bar 20 will hit the main pole of the tree. When the waterwheel continues to move, the slide bar 20 slowly swings counterclockwise with the hinge of the U-shaped plate 5 and the first connecting plate 2 as the axis. During this process, the fourth spring 26 gives The slide bar 20 thrusts in the opposite direction, making the slide bar 20 tightly attached to the main stem of the tree. As the waterwheel continues to move forward, the roller 39 will hook the main stem of the tree. At this time, the roller 39 drives the first guide cylinder 38 to move in the direction of the third limit ring 35, and the pressing plate 52 presses the open switch 54. When the open switch 54 is pressed, the electric valve 46 opens. At this time, because the roller 39 hooks the tree, as the waterwheel moves forward, the water stored in the cylinder 7 passes through the second L-shaped connecting pipe 15, the second connecting pipe 17, the third connecting pipe 18, the hose 47, and the first connecting pipe 45 in turn, and then is sprayed toward the root of the tree from the elbow port at the side end of the outlet pipe 44. When the spiral part of the guide slide groove 23 on the slide bar 20 is After passing through the guide chute 23, the slide bar 20 rotates 180° clockwise under the limiting action of the ball 22, and the roller 39 rotates synchronously with the slide bar 20, so that it no longer hooks the main pole of the tree. At this time, under the action of the first spring 29 and the third spring 33 and the water pressure in the water tank of the waterwheel, the slide bar 20 quickly resets. During the reset process, the piston 10 continues to suck the water in the water tank of the waterwheel into the cylinder 7 through the first L-shaped connecting pipe 13 for storage, preparing for watering the next tree in front. Then, by installing this device on the waterwheel, the purpose of automatic quantitative watering of trees can be achieved, without the need for manual operation by workers, saving labor and improving work efficiency. The hose 47 can be suspended on the guide rod 31 by the positioning clamp 48 and the ring 49 to prevent the hose 47 from falling to the bottom surface and avoid damage caused by friction between the hose 47 and the bottom surface.
