The design of the first hook and the second hook makes the movement of the striking hammer head more precise and controllable. When the hammer head is separated from the magnet, the compression spring releases energy, causing the hammer head to fall at high speed, thereby enhancing the striking effect. The device has a simple structure and low production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1 See also Figure 1-Figure 11 , a pile driver for tree planting, comprising a casing 1 and a striking mechanism 2, wherein a spraying mechanism 3 is arranged on a side end surface of the casing 1; A filling cylinder 102 is provided at the front end of the casing 1, a discharge port 104 is provided at the bottom of the casing 1, a magnet 101 is provided at the top of the casing 1, and handles 103 are provided on the left and right sides of the casing 1. A switch electrically connected to the motor 201 is provided on the handles 103; The striking mechanism 2 includes a motor 201, a first conveyor belt 202, a second conveyor belt 203 and a striking hammer 204. A first hook 2041 and a second hook 2042 are provided on the side of the striking hammer 204. A lifting rod 205 cooperating with the first hook 2041 is provided on the first conveyor belt 202. A tensioning wire 206 cooperating with the second hook 2042 is provided on the second conveyor belt 203. The spray mechanism 3 includes a liquid storage tank 301 , a filter plate 302 , a slide plate 303 , a compression spring 304 and a cam 305 . The inner end surface of the housing 1 is provided with a spray hole 1041 , and the side wall of the liquid storage tank 301 is provided with a liquid supply pipe 3011 which is connected to the spray hole 1041 .

[0022] Furthermore, the casing 1 includes an equipment room 105 and a guide cylinder 106, the motor 201, the first conveyor belt 202 and the second conveyor belt 203 are installed in the equipment room 105, the striking hammer head 204 is installed in the guide cylinder 106 and is slidably connected to the casing 1, the magnet 101 is fixedly installed on the top of the guide cylinder 106, a limiting groove 2043 is provided on the side of the striking hammer head 204, and a limiting strip 1061 that cooperates with the limiting groove 2043 is provided on the side of the guide cylinder 106.

[0023] The motor 201 drives the first conveyor belt 202 and the second conveyor belt 203 to rotate, so that the lifting rod 205 and the tensioning wire 206 drive the striking hammer 204 to reciprocate up and down, and under the action of inertia, the wooden stakes at the discharge port 104 are struck and knocked into the soil. The striking hammer 204 is prevented from rotating through the cooperation of the limiting groove 2043 and the limiting strip 1061, so that the first hook 2041, the lifting rod 205, the second hook 2042 and the tensioning wire 206 can cooperate accurately.

[0024] Furthermore, the first hook 2041 is inclined upward, the second hook 2042 is inclined downward, and the height of the second hook 2042 is lower than that of the first hook 2041. A fixed bracket 2023 is provided on the first conveyor belt 202, and the lifting rod 205 is fixedly installed on the fixed bracket 2023. A winding bracket 208 is provided on the second conveyor belt 203, and the tensioning wire 206 is slidably installed on the tensioning wire 206.

[0025] The first conveyor belt 202 drives the fixed bracket 2023 to rotate clockwise, and the second conveyor belt 203 drives the winding bracket 208 to rotate counterclockwise, and the upper end surface of the second hook 2042 is hung by the tensioning wire 206, and the striking hammer head 204 is pushed downward. When the striking hammer head 204 reaches the bottom, the tensioning wire 206 slips off the upper end surface of the second hook 2042. At this time, the lifting rod 205 pulls the first hook 2041 upward, thereby driving the striking hammer head 204 to move upward. When the striking hammer head 204 is close to the magnet 101, it is adsorbed by the magnet 101 on the top inner end surface of the casing 1.

[0026] Furthermore, the winding support 208 includes a support frame 2081 , a winding roller 2082 and a torsion spring 2083 . The winding roller 2082 is elastically rotatably connected to the support frame 2081 via the torsion spring 2083 . The left and right ends of the tensioning wire 206 are fixedly mounted on the winding roller 2082 .

[0027] When the tensioning wire 206 is hung on the downwardly pulled striking hammer 204, the tensioning wire 206 is stretched outward by the winding roller 2082, and the torsion springs 2083 at both ends undergo elastic deformation. When the elastic force of the torsion spring 2083 is greater than the suction force of the magnet 101, the elastic potential energy of the torsion spring 2083 is quickly converted into the kinetic energy of the striking hammer 204, causing the striking hammer 204 to fall at a high speed and strike the wooden pile, thereby improving the piling effect.

[0028] Furthermore, a first driving shaft 2021 keyed to the motor 201 is provided in the first conveyor belt 202, a second driving shaft 2031 is provided in the second conveyor belt 203, a rotatably connected transmission shaft 207 is provided in the housing 1, a first toothed umbrella 2022 is provided on the first driving shaft 2021, a second toothed umbrella 2032 is provided on the second driving shaft 2031, and a third toothed umbrella 2071 meshing with the first toothed umbrella 2022 and the second toothed umbrella 2032 is provided on the transmission shaft 207.

[0029] The first drive shaft 2021 and the second drive shaft 2031 cooperate with the first gear umbrella 2022, the second gear umbrella 2032 and the third gear umbrella 2071 to achieve synchronous reverse rotation, so that the striking hammer head 204 can achieve stable periodic up and down reciprocating motion, thereby striking the wooden pile.

[0030] Furthermore, the diameter of the discharge port 104 is smaller than the diameter of the guide tube 106 , a limiting ring 107 is disposed in the discharge port 104 , and a limiting spring 1071 is disposed at the bottom edge of the limiting ring 107 .

[0031] The retractable discharge port 104 limits the movement range of the striking hammer 204 to prevent the striking hammer 204 from falling from the discharge port 104. The limiting spring 1071 at the bottom of the limiting ring 107 grasps the side of the wooden pile, thereby increasing the friction between the wooden pile and the casing 1, thereby preventing the wooden pile in the guide cylinder 106 from falling under its own gravity during the movement of the equipment, thereby improving the convenience of operation.

[0032] Furthermore, the filter plate 302 is fixedly mounted on the inner end surface of the liquid storage tank 301, the slide plate 303 is installed in the liquid storage tank 301 and is slidingly sealed therewith, the compression spring 304 is installed between the slide plate 303 and the filter plate 302, the cam 305 is installed at the bottom of the slide plate 303 and is slidingly contacted therewith, a one-way valve 307 is provided at the top of the liquid storage tank 301, and a driven shaft 2036 is provided at the bottom of the second conveyor belt 203, and the driven shaft 2036 is connected to the cam 305 through a reducer transmission.

[0033] When the cam 305 rotates, the protrusion of the cam 305 squeezes the slide plate 303, causing the slide plate 303 to slide upward, thereby pressing out the liquid in the liquid storage tank 301, so that the liquid in the liquid storage tank 301 flows to the jet through the liquid supply pipe 3011 to spray the bottom of the wooden pile. The wooden pile can be sprayed with antiseptic or insect repellent agents, or with clean water. The excess liquid flows to the ground to keep the ground soft, thereby reducing the resistance to piling.

[0034] Furthermore, a threaded screw rod 306 is provided at the bottom of the liquid storage tank 301 , the top of the screw rod 306 is a ball-top structure, and a knob is provided at the bottom of the screw rod 306 .

[0035] By rotating the screw rod 306, the screw rod 306 pushes the slide plate 303 upward, thereby limiting the initial position of the slide plate 303, thereby adjusting the drainage volume of the liquid storage tank 301 when the cam 305 rotates one circle, thereby adapting to the soil with different humidity.

[0036] Furthermore, the bottom of the filling cylinder 102 is connected to the bottom of the guide cylinder 106 , and an inspection seam 1021 is provided at the center of the filling cylinder 102 .

[0037] A plurality of wood piles can be loaded at one time through the filling tube 102, so that rapid piling is achieved, which greatly improves the continuity of piling and thus the efficiency of piling. An inspection seam 1021 is provided at the center of the filling tube 102 to facilitate position adjustment of stuck wood piles.

[0038] Example 2 See also Figure 1-Figure 11 , a method for using a pile driver for tree planting, comprising the following steps: Step 1, filling materials. According to the needs, add an appropriate amount of pesticides, preservatives or clean water into the liquid storage tank 301, fill the wooden stakes of the seedling support frame into the filling tube 102 from top to bottom until the wooden stakes fill the filling tube 102. According to the hardness of the soil and the size of the wooden stakes, properly adjust the screw 306 to control the amount of liquid sprayed each time. If the soil is hard, the spraying amount can be increased to soften the soil; if the soil is wet, reduce the spraying amount; Step 2, spraying liquid, grasp the handle 103 with both hands, make the guide cylinder 106 vertically downward, connect the equipment to the external generator 201, mobile power supply or power strip through the wire, turn on the power, the motor 201 starts to work, and the lifting rod 205 on the first conveyor belt 202 cooperates with the first hook 2041 to make the striking hammer head 204 move upward, increase the gravitational potential energy of the striking hammer head 204, and at the same time, the transmission shaft 207 drives the cam 305 to rotate, and its protruding part squeezes the slide plate 303, so that the slide plate 303 slides upward, presses out the liquid in the liquid storage tank 301, and the liquid flows to the spray hole 1041 through the liquid supply pipe 3011, and is sprayed on the pile and the surrounding ground, thereby enhancing the anti-corrosion performance of the pile and softening the ground at the same time; Step 3, start piling, driving the first conveyor belt 202 and the second conveyor belt 203 to rotate, and the tensioning wire 206 on the second conveyor belt 203 cooperates with the second hook 2042 to make the striking hammer head 204 slide downward at high speed under the action of elastic potential energy and gravitational potential energy, striking the bottom wooden pile and knocking the wooden pile into the soil.

[0039] After completing the piling at one location, carefully move the equipment to the next location, making sure that the wooden pile can be aligned with the next piling point. During use, ensure that the equipment is placed stably to prevent the wooden pile from tilting during the hammering process. Repeat the above steps to perform continuous piling around the sapling.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
