[0053] A method for using a base improvement device for lake ecosystem construction comprises the following steps:

[0054] S1: Connect the connecting ring 103 provided on the frame 101 to the tractor.

[0055] S2: Start the lifting motor 203. The output shaft of the lifting motor 203 drives the lead screw 202 to rotate, so that the lifting frame 201 threadedly matched with the lead screw 202 moves downward along the frame 101, and the loosening mechanism 3 moves to a suitable height.

[0056] S3: Pull out the limit pin 310 from the tightening rod 309, and manually rotate the tightening rod 309 so that the tightening rod 309 drives the edge gear 308 to rotate, so that the edge gear 308 drives the central gear 306 to rotate, thereby making the loosening rod 304 slide out of the circular shell 301 and adjust the thickness of the loosened soil by the loosening rod 304.

[0057] S4: Start the tractor and the loosening motor 212, so that the loosening rods 304 move forward to loosen the soil. At the same time, the distance between the loosening rods 304 can also change continuously to improve the loosening efficiency. At the same time, the disinfectant flows from the hopper 411 into the discharge plate 412 and falls to the ground from the discharge hole 413 on the discharge plate 412.

[0058] Working principle: firstly, the connecting ring 103 is connected to the tractor, and the tractor pulls the frame 101 and the lifting mechanism 2, the loosening mechanism 3, the disinfection mechanism 4, and the smoothing plate 5 to move.

[0059] Then, the lifting motor 203 fixedly mounted on the frame 101 is started, and the lead screw 202 is driven to rotate by the output shaft of the lifting motor 203. Since the lifting frame 201 is threadedly matched with the lead screw 202, and the short rods 206 fixedly connected on both sides of the lifting frame 201 are slidably matched with the vertical grooves 102 on the frame 101, during the rotation of the lead screw 202, the lifting frame 201 will gradually slide to the side close to the ground, so that the loosening mechanism 3 installed on the spline shaft 219 will also gradually approach the ground. Of course, during the descent of the lifting frame 201, the driving plate 215 will also descend, and the bidirectional threaded rod 208 threadedly connected on the driving plate 215 will also slide downward along the horizontal plate 213. The horizontal plate 213 is fixedly mounted on the frame 101. At the same time, since the central shaft 209 and the bidirectional threaded rod 208 are splined, the central shaft 209 will not affect the movement of the bidirectional threaded rod 208.

[0060] When the loosening mechanism 3 reaches the appropriate position, the lifting motor 203 is turned off, and the limit pin 310 on the tightening rod 309 is pulled out at the same time, and the limit pin 310 leaves the limit hole 303 on the circular shell 301, so that the tightening rod 309 will not be restricted. At this time, the staff manually rotates the tightening rod 309 to make the tightening rod 309 drive the edge gear 308 to rotate inside the circular shell 301. The edge gear 308 is meshed with the center gear 306, so the center gear 306 will also rotate. During the rotation of the center gear 306, the arc groove 307 set on the center gear 306 will push the loosening rod 30 4. Make the loosening rod 304 slide out from the outer groove 302 set on the circular shell 301, so that the loosening rod 304 gradually moves away from the center of the circular shell 301. The purpose of this is to flexibly adjust the length of the loosening rod 304 extending out of the circular shell 301, that is, the depth of loosening. After the loosening rod 304 reaches the required loosening depth, the limit pin 310 is inserted into the tightening rod 309 again, and the limit pin 310 is inserted into the limit hole 303, so that the tightening rod 309 will not rotate. In this process, the reset spring 2 305 will be compressed. The function of the reset spring 2 305 is to assist the reset of the loosening rod 304.

[0061] After the extension length of the loosening rod 304 is adjusted, the tractor is started to move forward, and the loosening motor 212 is started at the same time. The output shaft of the loosening motor 212 drives the active bevel gear 211 and the belt assembly 214 to rotate; since the active bevel gear 211 is meshed with the driven bevel gear 210, the active bevel gear 211 will drive the driven bevel gear 210 to rotate, and the central shaft 209 fixedly connected to the driven bevel gear 210 will rotate on the frame 101, and the central shaft 209 is meshed with the bidirectional threaded rod 208, so the bidirectional threaded rod 208 will rotate relative to the horizontal plate 213, so that the driving plate 215 that forms a threaded fit with the bidirectional threaded rod 208 will slide along the guide rail 207, then the driving plate 215 will rotate relative to the horizontal plate 213, and the driving plate 215 that forms a threaded fit with the bidirectional threaded rod 208 will slide along the guide rail 207, and then the driving plate 215 will rotate relative to the horizontal plate 213. The inclined guide groove 217 arranged on the plate 215 will push the moving block 216 to slide on the horizontal guide rod 204, and the sliding moving block 216 will move with the lever 218, and the lever 218 is rotated in cooperation with the circular shell 301, so at this time the circular shell 301 will slide along the spline shaft 219 under the action of the lever 218, and the deformed return spring 205 in this process plays a role in resetting the moving block 216; when the belt assembly 214 rotates, the spline shaft 219 connected to the belt assembly 214 will rotate, and then the circular shell 301 that forms a spline cooperation with the spline shaft 219 will rotate, so that the loosening rod 304 in the circular shell 301 will rotate on the ground, thereby completing the loosening of the soil. Since the two-way threaded rod 208 is a two-way thread, the driving plate 215 can move up and down reciprocatingly, thereby constantly adjusting the position between the moving blocks 216, and the purpose of doing so is to adjust the distance between the lever 218 by the moving block 216, so that the lever 218 adjusts the distance between the circular shell 301, so that the loosening position of the loosening rod 304 can be adjusted, so that the loosening is more thorough, and dead angles are prevented, and in this process, the loosening rod 304, in addition to rotating, also includes movement along the forward direction of the tractor, and also includes movement along the axial direction of the spline shaft 219, so that the loosening rod 304 can also break the soil in the soil during the loosening process. It should be noted that the belt assembly 214 includes two pulleys and a belt, one pulley is installed on the output shaft of the loosening motor 212, and the other pulley is installed on the spline shaft 219, and the two pulleys are connected by a belt, which is conceivable for those skilled in the art.

[0062] When the moving block 216 slides along the horizontal guide rod 204, the rotating arm 402 connected to the moving block 216 will also move, and the moving rotating arm 402 will reciprocate to push the long rod 403, so that the long rod 403 slides on the disinfection mounting frame 401, and then the wedge block 405 on the long rod 403 will slide with the ball head rod 406. Since the shape of the wedge block 405 is high at one end and low at the other end, when the higher end of the wedge block 405 contacts the ball head rod 406 during the movement of the wedge block 405, the end of the ball head rod 406 close to the wedge block 405 is lifted, so that the ball head rod 406 is close to the lower One end of the material rod 410 will lower. On the contrary, when the lower end of the wedge block 405 contacts the ball head rod 406, the end of the ball head rod 406 close to the wedge block 405 will lower, so that the end of the ball head rod 406 close to the discharge rod 410 will rise. The purpose of this is to make the discharge rod 410 move up and down intermittently along the inside of the hopper 411. On the one hand, it is to stir the medicine in the hopper 411 to prevent the inside of the hopper 411 from being blocked. On the other hand, when disinfection is not performed, the lower end of the discharge rod 410 can block the lower end of the hopper 411 to prevent the disinfectant from falling into the discharge plate 412. During the continuous stirring process of the lower material rod 410, the disinfectant powder in the hopper 411 falls into the discharge plate 412, and then falls from the discharge hole 413 set on the discharge plate 412 to the soil just loosened by the loosening rod 304, thereby disinfecting and sterilizing the soil. The smoothing plate 5 located behind the frame 101 is used to level the loosened soil and the soil sprinkled with disinfectants. Since there will still be a large number of clods of soil after the soil is turned over by the loosening rod 304, a plurality of conical rods can be set on the side of the smoothing plate 5 close to the ground, so that the conical rods can be used to break the clods of soil when the smoothing plate 5 moves forward.
