[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: a soil-turning equipment, including a lower bracket 1, on which a threaded adjustment column 102 is rotatably installed, and a rotating disk 103 is fixedly connected to the upper end of the threaded adjustment column 102. An upper bracket 2 is arranged above the lower bracket 1, and a threaded sleeve 203 is embedded in the upper bracket 2. The threaded sleeve 203 is threadedly matched with the threaded adjustment column 102, and a connecting pin sleeve 204 is embedded in the upper bracket 2 near the front end edge. A connecting frame 3 is symmetrically fixed to the bottom of the lower bracket 1, and a soil-turning roller shaft 5 is rotatably installed between the two connecting frames 3, and a plurality of plow blades 501 are fixed on the soil-turning roller shaft 5.

[0024] In this embodiment, agricultural machinery can be connected by using a pin to pass through the threaded sleeve 203, thereby connecting the upper bracket 2 to the agricultural machinery. The rotating soil-turning roller 5 can drive the plow 501 to rotate. The rotation of the plow 501 will turn the soil over, thereby turning the soil. The threaded sleeve 203 is threadedly matched with the threaded adjustment column 102. The rotating threaded adjustment column 102 can drive the lower bracket 1 to move. The movement of the lower bracket 1 can drive the soil-turning roller 5 to move through the connecting frame 3, thereby adjusting the height of the plow 501 and the depth of the soil turning by the plow 501.

[0025] Among them, in order to achieve the purpose of driving the soil-turning roller shaft 5 to rotate, this device adopts the following technical solutions: a limit slide bar 101 is fixed on the upper side of the lower bracket 1 and on both sides of the threaded adjustment column 102, and a slide hole 202 is symmetrically opened in the upper bracket 2. The slide hole 202 slides with the limit slide bar 101. A power motor 104 is fixed on the upper side of the lower bracket 1 near the edge of one side, and a driving pulley 105 is fixed on the output end of the power motor 104. A driven pulley 504 is fixed on one end of the soil-turning roller shaft 5. The driving pulley 105 and the driven pulley 504 are linked by a transmission belt 106. A fender 107 is fixed to the back of the lower bracket 1, and a battery box 9 is fixed to the upper side of the lower bracket 1 near the rear edge.

[0026] The sliding hole 202 slides with the limiting slide bar 101 to limit the lower bracket 1 to move up and down. Starting the power motor 104 can drive the active pulley 105 to rotate. The active pulley 105 can drive the driven pulley 504 to rotate through the transmission belt 106. The rotation of the driven pulley 504 will drive the soil roller 5 to rotate, and then drive the plow 501 to rotate at high speed. The mudguard 107 prevents the plow 501 from rotating at high speed and carrying soil out from the rear. A battery pack is provided inside the battery box 9 to provide electricity for the power motor 104.

[0027] Among them, in order to facilitate the removal of the soil roller shaft 5, the present device adopts the following technical solutions: a clamping block 301 is hingedly connected to the bottom of the connecting frame 3, an upper mounting groove 302 is provided under the connecting frame 3, a lower mounting groove 303 is provided on the clamping block 301, and a limiting groove 304 is provided in both the upper mounting groove 302 and the lower mounting groove 303. A fixed protrusion 305 is fixedly connected to the top of the connecting frame 3 near the front edge, and a limiting hole 306 is provided in the fixed protrusion 305. A clamping slot 307 is provided under the connecting frame 3 near the front edge. The clamping slot 307 Cooperating with the fixed protrusion 305, the outer wall of one side of the connecting frame 3 is fixedly connected to the limiter 4, and a limiting groove 401 is provided in the limiter 4. A limiting pin 402 is slidably installed in the limiting groove 401. A spring pad 403 is fixedly connected to the limiting pin 402, and a return spring 404 is sleeved on the limiting pin 402. A displacement handle 405 is fixedly connected to one end of the limiting pin 402. The soil-turning roller 5 is rotatably installed with a bearing sleeve 502 near the edges of both ends. A limiting ring 503 is fixedly connected to the outer wall of the bearing sleeve 502, and the limiting ring 503 cooperates with the limiting groove 304.

[0028] The lower mounting groove 303 and the upper mounting groove 302 can form a circular mounting groove for fixing the bearing sleeve 502, and the upper limit ring 503 of the bearing sleeve 502 cooperates with the limit groove 304 to limit the left and right movement of the connecting frame 3 installed in the formed circular mounting groove. The return spring 404 can provide a certain thrust for the spring pad 403. After the spring pad 403 is thrust, it will drive the limit pin 402 to insert into the limit hole 306, and then fix the fixing protrusion 305 in the slot 307 to fix the block 301. Pull the displacement handle 405 to drive the limit pin 402 to move out of the limit hole 306, and the fixation of the fixing protrusion 305 can be released. At this time, the block 301 can be rotated to open. Figure 3 As shown, the bearing sleeve 502 can be easily removed at this time, making it easy to remove the soil roller shaft 5 for maintenance at a later time.

[0029] The working principle and usage process of the present invention are as follows: when in use, the device needs to be connected to agricultural machinery with a pin, and the agricultural machinery is used to drag the device to move in the field. Starting the power motor 104 can drive the soil-turning roller 5 to rotate. The rotation of the soil-turning roller 5 will drive the plow blade 501 to rotate at high speed. Then, rotating the rotating disk 103 can drive the threaded adjustment column 102 to rotate. The rotation of the threaded adjustment column 102 can drive the height of the lower bracket 1. The connecting frame 3 can be used to drive the soil-turning roller 5 to move, and then the depth of soil turning can be adjusted. The device is moved in the field by using agricultural machinery to drag the device to move in the field, and the field can be turned over. When the soil-turning roller 5 needs to be maintained in the later stage, the displacement handle 405 is pulled to drive the limit pin 402 to move out of the limit hole 306, so that the fixation of the fixed protrusion 305 can be released. At this time, the block 301 can be rotated open. At this time, the bearing sleeve 502 can be easily removed, and the soil-turning roller 5 can be removed from the device separately.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
