[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a tree-planting pit digger with a soil retaining structure, which includes a pit digger body 1, a drill bit 2 is installed on the lower surface of the pit digger body 1, a mud retaining mechanism 3 is arranged on the lower surface of the pit digger body 1, and a support mechanism 4 is arranged on the lower surface of the pit digger body 1;

[0021] The mud retaining mechanism 3 includes a housing 301, a mounting hole 302, a sealing ring 303, a telescopic cover 304 and a spring 305. A housing 301 is installed on one side surface of the pit digger body 1, a mounting hole 302 is opened on the upper surface of the housing 301, a sealing ring 303 is connected to the inner surface of the mounting hole 302, a telescopic cover 304 is installed on the inner surface of the housing 301, and a spring 305 is connected to the upper surface of the telescopic cover 304. Through the settings of the housing 301, the mounting hole 302, the sealing ring 303, the telescopic cover 304 and the spring 305, during use, the sealing ring 303 is installed on the top of the drill bit 2 and connected to the pit digger body 1 through the mounting hole 302. At the same time, a spring 305 is installed on the top of the telescopic cover 304, and the whole is installed in the cavity in the housing 301. During the tree-planting pit digging work, the spring 305 will push out the telescopic cover 304 to make it fit with the ground. At the same time, the drill bit 2 digs the mud surface, and the splashed soil will be blocked by the telescopic cover 304.

[0022] Furthermore, the support mechanism 4 includes a fixed housing 401, a connecting frame 402, a grip 403, a telescopic frame 404 and a fixed frame 405. The lower surface of the pit digger body 1 is equipped with the fixed housing 401. The outer surface of the fixed housing 401 is fixedly connected to the connecting frame 402. The inner surface of the connecting frame 402 is fixedly connected to the grip 403. The telescopic frame 404 is installed on the lower surface of the connecting frame 402. The lower surface of the telescopic frame 404 is fixedly connected to the fixed frame 405. Through the settings of the fixed housing 401, the connecting frame 402, the grip 403, the telescopic frame 404 and the fixed frame 405, during use, the drill bit 2 is passed through the fixed housing 401 to be connected to the pit digger body 1. At the same time, the connecting frame 402 and the grip 403 are installed on the outside of the fixed housing 401, and the telescopic frame 404 and the fixed frame 405 are installed below the connecting frame 402. During use, the entire device is carried to the position where a pit needs to be dug through the grip 403, and at the same time, the height of the telescopic frame 404 is adjusted to make it in a predetermined position.

[0023] Furthermore, the inner wall size of the outer shell 301 matches the outer wall size of the telescopic cover 304, and the inner wall size of the mounting hole 302 matches the outer wall size of the sealing ring 303. Through the setting of the sealing ring 303, during use, the sealing ring 303 can prevent soil from leaking out through the connection between the drill bit 2 and the pit digger body 1 when digging a pit.

[0024] Furthermore, the inner wall size of the sealing ring 303 matches the outer wall size of the drill bit 2, and multiple groups of telescopic covers 304 are provided. Through the setting of the telescopic covers 304, during use, the telescopic covers 304 will gradually contract as the drill bit 2 penetrates, so that it always remains in a range that can just block the splashed soil.

[0025] Furthermore, one end surface of the spring 305 is connected to the outer shell 301, and the other end surface of the spring 305 is connected to the telescopic cover 304. Through the setting of the spring 305, during use, the spring 305 makes the telescopic cover 304 always remain in the extended state and always fit tightly with the mud surface, further preventing soil from splashing.

[0026] Furthermore, the grips 403 are symmetrically installed with respect to the length central axis of the fixed housing 401, and multiple groups of grips 403 are provided. Through the setting of the grips 403, during use, the grips 403 can always provide a stress point when carrying the entire device, effectively saving physical strength consumption during carrying.

[0027] Furthermore, the telescopic frames 404 are symmetrically installed with respect to the central axis of the connecting frame 402, and a sharp cone is provided on the lower surface of the fixed frame 405. Through the setting of the telescopic frames 404, during use, the telescopic frames 404 will also gradually contract as the drill bit 2 penetrates, so that it remains at a reasonable length. At the same time, the sharp cone at the bottom of the fixed frame 405 enables it to be stably supported on the mud surface.

[0028] Working principle: Install the sealing ring 303 on the top of the drill bit 2, connect it to the pit-digging device body 1 through the mounting hole 302. At the same time, install the spring 305 on the top of the telescopic cover 304, and install the whole into the cavity in the outer shell 301. When carrying out the work of afforestation and pit-digging, the spring 305 will push out the telescopic cover 304 to make it fit with the ground. At the same time, the drill bit 2 digs the mud surface, and the splashed soil will be blocked by the telescopic cover 304. Install the connecting frame 402 and the grip 403 on the outside of the fixed shell 401, and install the telescopic frame 404 and the fixed frame 405 below the connecting frame 402. When in use, carry the whole device to the position where pit-digging is needed through the grip 403, and at the same time adjust the height of the telescopic frame 404 to make it in a predetermined position.
