The use method and the advantages of the invention are as follows: the accessory connecting device for the ground leveling equipment is operated as follows when in use, and comprises the following steps:

the method comprises the following steps: mounting of the connecting frame 2: the T-shaped groove 21 on the lower surface of the connecting frame 2 corresponds to the tailstock 1, and the connecting frame 2 is moved downwards to clamp the T-shaped groove 21 on the tailstock 1, the installation mode is simple and convenient to operate without welding or bolt fixation, and the connecting frame 2 and the tailstock 1 are in a wrapping connection mode, so that the connection strength is greatly improved, after the connecting frame 2 is connected on the tailstock 1, the sliding rod 11 is extruded downwards by the connecting frame 2 to move downwards along the guide through hole 20, the pull rod 7 is pulled to be close to the connecting frame 2 along the guide sleeve 9 through the connecting rod I10, the sliding sleeve 4 is further close to the connecting frame 2 and simultaneously compresses the spring I8, the spring I8 obtains a restoring force, the pressure plate 6 is synchronously close to the connecting frame 2 due to the movement of the sliding sleeve 4 and is pressed and buckled on the connecting frame 2, and the phenomenon that the connecting frame 2 jumps up and down when a fuel driver drives the accessory frame body 3 to work is avoided, ensuring the stability of the connection;

in the process that the sliding sleeve 4 approaches the connecting frame 2, the extending plate 5 synchronously approaches the connecting shaft rod 12 and enables one end of the connecting shaft rod 12, which points to the fuel driver, to pass through the through hole in the extending plate 5, after the connecting shaft rod 12 passes through the through hole in the extending plate 5, the connecting nut 15 is connected to the end of the connecting shaft rod 12 so that the connecting shaft rod 12 is firmly connected with the extending plate 5, and then the accessory frame body 3 is connected to the connecting frame 2 and the hanging bracket 18 through two connecting rods three 19 according to the mode shown in fig. 1;

step two: the fuel driver drives the accessory frame body 3 to work: after the connecting frame 2 and the accessory frame body 3 are connected, a fuel driving machine is started to work, the fuel driving machine drives the accessory frame body 3 to work through the tailstock 1 and the connecting frame 2, when the accessory frame body 3 works along with the advancing direction of the fuel driving machine, when the accessory frame body 3 meets a large reaction force transmitted by the ground, the accessory frame body 3 moves rightwards relative to the connecting frame 2, and a right pulling force is applied to the connecting shaft rod 12, so that the connecting shaft rod 12 moves rightwards and compresses the second spring 14, the second spring 14 shortens energy storage, a buffering effect is achieved on vibration transmitted by the accessory frame body 3, a protection effect is achieved on the whole equipment, and the service life of the equipment is prolonged;

because the right movement of the connecting shaft rod 12 drives the upper end of the connecting rod II 16 to rotate clockwise around the lower end of the connecting rod II 16, the connecting shaft rod 12 can only perform horizontal linear motion under the limiting action of the connecting frame 2 and the extension plate 5, and the included angle between the connecting rod II 16 and the tilting rod 17 is larger than 90 degrees, in the clockwise rotation process of the connecting rod II 16 around the lower end of the connecting rod II, the included angle between the connecting rod II 16 and the tilting rod 17 is gradually reduced, and simultaneously, the connecting rod II 16 enables the connecting rod II 16 to integrally move downwards while rotating clockwise around the lower end of the connecting rod II under the constraint action of the connecting shaft rod II 12 in the vertical direction, so that the left end of the tilting rod 17 moves downwards, according to the lever principle, the right end of the tilting rod 17 does opposite movement to the left end of the tilting rod 17, so that the accessory frame body 3 is tilted upwards at the right end of the tilting rod 17, after the accessory frame body 3 is tilted and lifted, the connecting depth of the ground is reduced, the accessory frame body 3 can work smoothly, so that the tensile stress and the shear stress of the connecting frame 2 are reduced, the damage probability is greatly reduced, the working efficiency is improved, after the accessory frame body 3 passes through a large reaction force transmitted by the ground, the restoring force of the second spring 14 enables the connecting shaft rod 12 to move leftwards and reset, the second connecting rod 16 and the tilting rod 17 reset, the accessory frame body 3 correspondingly resets to the initial height, and the work is continued;

it should be noted that when the connecting shaft rod 12 moves rightwards, the screw cap 15 drives the extending plate 5 and the sliding sleeve 4 to synchronously move rightwards, and the right movement of the sliding sleeve 4 drives the pressing plate 6 to synchronously move rightwards, so that the connecting frame 2 is better pressed and buckled on the tailstock 1, and the connecting stability of the connecting frame 2 and the tailstock 1 when the attachment frame body 3 meets strong ground reaction force can be enhanced;

step three: disassembling the connecting frame 2: after the use of the data frame body 3 is finished, the fuel driving machine stops working, firstly, the accessory frame body 3 is detached from the connecting frame 2, then the screw cap 15 is screwed down from the end part of the connecting shaft rod 12, the sliding sleeve 4 moves leftwards under the restoring force action of the first spring 8, and meanwhile, the pressing plate 6 is driven to be away from the connecting frame 2, the same extension plate 5 is also separated from the connecting shaft rod 12, the connecting rod 10 is pulled through the pull rod 7 in the process that the sliding sleeve 4 is away from the connecting frame 2, upward force is applied to the sliding rod 11 through the connecting rod 10, so that the sliding rod 11 moves upwards along the guide through hole 20 to jack the connecting frame 2, and finally, the connecting frame 2 is taken down from the tailstock 1, and the disassembly is convenient.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
