[0022] The four mounting plates 201 are fixedly connected to the top of the support frame 101, and the connecting column 308 slides through the mounting plate 201. The counterweight block 309 is located above the mounting plate 201 and the counterweight block 309 and the mounting plate 201 do not fit together. The connecting column 308 is used to connect the counterweight block 309 and the circular frame 304, so that the counterweight block 309 and the piston 302 form a whole. At the same time, the height of the counterweight block 309 is increased by the connecting column 308, so that it is located above the mounting plate 201, which is convenient for replacement.

[0023] A water supply pipe 310 is fixedly connected to a position near the top of the outer surface of the fixed cylinder 301, and a water supply pipe 104 is fixedly connected to the bottom of the water tank 103. The bottom end of the water supply pipe 104 is fixedly connected to a position near the bottom of the outer surface of the fixed cylinder 301, and a one-way valve 105 is installed on the outside of the water supply pipe 104 near the fixed cylinder 301. The water supply pipe 310 is provided to connect the water tank 103 and the fixed cylinder 301, so that the water inside the water tank 103 can be supplied to the inside of the fixed cylinder 301, and the one-way valve 105 provided on the surface of the water supply pipe 310 only allows the fluid to flow from the inside of the water tank 103 to the inside of the fixed cylinder 301, thereby limiting the flow direction of the liquid.

[0024] The connecting shell 401 is fixedly connected to the bottom of the mounting plate 201 and the connecting shell 401 is provided with multiple output ports and an input port. The input port of the connecting shell 401 is connected to the water supply pipe 310. The output end of the connecting shell 401 is fixedly connected with a connecting pipe 402. The connecting pipe 402 extends upward at one end away from the connecting shell 401 and passes through the surface of the mounting plate 201. The top of the connecting pipe 402 is fixedly connected with a hose 403. A nozzle 404 is installed at the top of the hose 403. The connecting pipe 402 is a hard pipe for connecting the hose 403 and the output port of the connecting shell 401. When in use, after the water inside the fixed cylinder 301 is sent into the connecting shell 401 through the water supply pipe 310, as the water source is continuously transported, the connecting shell 401, the water supply pipe 310 and the fixed cylinder 301 will be in a full water state and supplied to the nozzle 404 through the connecting pipe 402 and the hose 403. Finally, the water is sprayed in a mist form onto the soil at the roots of the tree through the nozzle 404.

[0025] A damper 206 is fixedly connected to the center of the top of the mounting plate 201, and a connecting sleeve 208 is fixedly connected to the top of the damper 206. The bottom of the connecting sleeve 208 is provided with an opening and a first spring 207 is provided between the inner surface wall of the connecting sleeve 208 and the outer surface of the damper 206. A hollow tray 210 is fixedly connected to the top of the connecting sleeve 208, and a pad 211 is placed on the top of the hollow tray 210. The top of the hollow tray 210 is concave inward. When in use, the damper 206 cooperates with the first spring 207 to play a role in buffering and absorbing energy. The instantaneous impact force on the tree above the connecting sleeve 208 during transportation is reduced, and the first spring 207 is set to push the connecting sleeve 208 upward in the initial state. A hollow tray 210 is set on the top of the connecting sleeve 208 to increase the supporting area of the bottom of the tree. The surface of the mat 211 is covered with micropores, which increases the contact area between the hollow tray 210 and the tree roots. When there is too much water in the soil at the bottom of the tree roots, it can be discharged in time through the mat 211 to avoid the tree roots from losing vitality after being soaked.

[0026] A plurality of first rotating seats 202 are fixedly connected at equal intervals to the top of the mounting plate 201, and the plurality of first rotating seats 202 are circumferentially distributed on the outside of the damper 206. The outer surface of the first rotating seat 202 is rotatably connected to the first connecting rod 203 extending upward, and the first connecting rod 203 is arranged at an angle. The first rotating seat 202 is used to rotatably connect the bottom end of the first connecting rod 203 and the top of the mounting plate 201. In the initial state, the first connecting rod 203 is in an inclined state. When the first connecting rod 203 is pulled by the second connecting rod 205, it will further tilt, and the bottom end of the first connecting rod 203 and the first rotating seat 202 will rotate during the process.

[0027] The back sides of the plurality of first connecting rods 203 near the top are fixedly connected with a pressure rod 204, and the pressure rod 204 is arranged in an arc shape. The outside of the nozzle 404 is rotatably connected to a connecting seat 405 through a damping shaft. The connecting seat 405 is fixedly connected to the outer surface of the pressure rod 204 near the top. The pressure rod 204 is connected to the first connecting rod 203 near the top. The plurality of pressure rods 204 form a claw shape, which plays a role of pressing the soil ball when close to each other, and cooperates with the later rope binding to reinforce the tree trunk position to achieve the purpose of fixing the tree. The connecting seat 405 is used to fix the nozzle 404 at the position of the pressure rod 204 near the top. Therefore, when the end of the pressure rod 204 is pressed on the surface of the soil ball, the nozzle 404 is close to the soil ball, and the nozzle 404 is connected to the connecting seat 405 through the damping shaft, and the spraying angle of the nozzle 404 can be adjusted by rotation.

[0028] A plurality of second rotating seats 209 are fixedly connected at equal intervals near the top of the outer surface of the connecting sleeve 208. The number of the second rotating seats 209 and the first rotating seat 202 are the same and the positions are corresponding. A second connecting rod 205 is rotatably connected between the inner surface walls of the second rotating seat 209. The end of the second connecting rod 205 away from the second rotating seat 209 is rotatably connected to the top of the first connecting rod 203. The second rotating seat 209 is used to rotatably connect the second connecting rod 205 and the connecting sleeve 208, and the adjacent ends of the second connecting rod 205 and the first connecting rod 203 are rotatably connected. When in use, the downward movement of the connecting sleeve 208 will drive the second rotating seat 209 to descend synchronously. At this time, the second rotating seat 209 pulls down the inner end of the second connecting rod 205 to descend, and the second connecting rod 205 tilts as a whole, and the outer end will pull the first connecting rod 203 inward to retract, thereby driving the pressure rod 204 to retract and press the soil lump to limit it.

[0029] The effect and working principle achieved by the entire mechanism are as follows: the support frame 101 is fixed in the carriage of the transport vehicle, and the water in the water tank 103 is filled. In the initial state of the device, the elastic force generated by the first spring 207 in the fixing component 2 will push the connecting sleeve 208 upward to move to the maximum height. At this time, the second connecting rod 205 is in a horizontal state, and the multiple pressure rods 204 are in an open state. When in use, after the roots of the transplanted trees are connected to the soil for fixing, the bottom of the tree is placed on the pad 211 of the fixing component 2. At this time, the weight of the tree acts on the hollow tray 210. After the hollow tray 210 presses the connecting sleeve 208 downward, it squeezes the first spring 207 and the damper 206 to contract. During the process, the downward movement of the connecting sleeve 208 will drive the second rotating seat 209 to synchronously descend. At this time, the second rotating seat 209 pulls down the inner end of the second connecting rod 205, and the second connecting rod 205 descends. The whole structure tilts, and one end outside pulls the first connecting rod 203 inwardly to retract. Therefore, when the tree is placed on the mat 211 of the fixing assembly 2, all the first connecting rods 203 will move together synchronously without the need for driving, and the pressure rods 204 on the surface of the first connecting rod 203 will move synchronously and press on the soil at the root of the tree to fix it. Then, the tree trunk is wrapped with a binding rope and then fixed to the hook on the side of the transport vehicle. At this time, the root of the tree is supported and limited by the fixing assembly 2, and the tree trunk is fixed with a pull rope to ensure stability during long-distance transportation. Moreover, during unloading, as the tree is lifted and separated from the fixing assembly 2, the first spring 207 loses its squeezing force and rebounds, prompting the fixing assembly 2 to recover. No additional operation is required. This design ensures the stability of the tree while simplifying its fixing and disassembly methods, reducing labor costs and improving overall transplanting efficiency. When the tree is fixed on the transport vehicle for long-distance transportation by using the fixing assembly 2 in conjunction with the pull rope, as the vehicle bumps, the damper 206 and the first spring 207 can buffer and absorb energy, reducing the instantaneous impact force and shaking amplitude of the tree, and the counterweight 309 will shake up and down when it is bumped. When the counterweight 309 moves downward, the connecting column 308 drives the piston 302 to move downward in the fixing cylinder 301 through the circular frame 304. At this time, the third spring 307 contracts to store energy, and the counterweight 309 moves upward. When the piston 302 moves upward, the third spring 307 will release energy to assist, thereby increasing the vibration amplitude of the counterweight 309. During the descent of the piston 302, the space below the fixed cylinder 301 is reduced and the pressure is increased. The second spring 305 has a small elasticity and the rubber plate 306 is pushed upward under the action of the pressure. At this time, the internal space of the fixed cylinder 301 is in a connected state under the action of the connecting port 303. During the upward movement of the piston 302, the space below is increased and the pressure is reduced. At this time, under the negative pressure Under the action of the rubber plate 306, the rubber plate 306 will be adsorbed on the top of the piston 302 and block the communication port 303. At the same time, the suction force generated when the negative pressure is formed inside the fixed cylinder 301 will draw the water in the water tank 103 into the fixed cylinder 301 through the one-way valve 105 and the water supply pipe 104. During the reciprocating movement of the piston 302, the water in the water tank 103 will continue to enter the fixed cylinder 301 and fill the fixed cylinder 301. As the piston 302 moves upward in a closed state, the water will be pressed out from the water supply pipe 310 and enter the communication shell 4 01. With the continuous delivery of water, the connecting shell 401, the water supply pipe 310 and the fixed cylinder 301 will be full of water and supplied to the nozzle 404 through the connecting pipe 402 and the hose 403. Finally, the water is sprayed in the form of mist onto the soil at the roots of the tree through the nozzle 404. This design utilizes the vibration generated during the transportation of trees by the vehicle, and can continuously supply water to the nozzle 404 at a small flow rate, and then gently spray it on the soil at the bottom of the tree roots to moisturize. It has a simple structure and low cost, which solves the workload caused by manual water replenishment.
