[0007] According to the above technical solution, the triangle plate contacts the positioning groove, and a sliding groove is provided on the side of the digging claw away from the rotating rod. When the rotating rod rotates clockwise, the triangle plate will be flipped in the clockwise direction due to the limitation of the positioning groove.

[0008] According to the above technical solution, a second slide groove is provided on one side of the digging claw close to the rotating rod, and the push plate is slidably installed in the second slide groove. When the push plate moves, the soil on the inner wall of the digging claw will be scraped off.

[0013] According to the above technical solution, the trapezoidal block contacts the semi-cylinder, and the bottom of the wide plate contacts the top of the telescopic mechanism. When the trapezoidal block contacts the semi-cylinder, vibration will occur, and when the telescopic mechanism moves upward, it will deviate due to the obstruction of the wide plate.

[0014] The present invention provides a soil digging device for landscaping, which has the following beneficial effects: (1) In the present invention, when the telescopic column moves, it drives the spiral rod to rotate, and when the spiral rod rotates, it drives the straight plate to move, and when the straight plate moves, it drives the push plate to move, so that the soil on the digging claws can be pushed away and cleaned, thereby preventing the soil from sticking to the digging claws and affecting the subsequent digging. When the spiral rod rotates, it drives the rotating rod to move, and when the rotating rod moves, it drives the dispersing column to move, thereby breaking up the soil in the digging claws and the weeds inside, thereby preventing the soil from affecting the subsequent growth of plants and preventing the seeds from being buried by the lumps of soil.

[0015] (2) In this invention, when the push column moves, it will drive the push plate to move, and when the push plate moves, it will drive the telescopic plate to move, which can effectively control the number of seeds sown and prevent the staff from forgetting to water. When the digging claw moves, it will drive the receiving column to move, and when the receiving column moves, it will drive the hook plate to move, so that the cover plate is opened, which can match the speed of the digging claw. At the same time, it can greatly increase the sowing speed and reduce the time required for manual sowing, thereby improving the overall work efficiency. At the same time, it can achieve precise sowing depth and spacing, ensure the best growth conditions for seeds, and thus improve the germination rate and yield of crops.

[0016] (3) In this invention, when the telescopic mechanism moves, it will drive the sieve claws to move, so that the stones in the soil in front can be removed in advance to prevent the growth of plants from being affected. When the trapezoidal block moves, it will contact the semi-cylinder on the baffle plate. When the trapezoidal block contacts the semi-cylinder, it will vibrate. When the trapezoidal block vibrates, it will drive the sieve claws to vibrate, causing the stones above to fall. It can also clean up some stones stuck in the gaps of the sieve claws to prevent them from being blocked in subsequent screening. At the same time, it can make the materials more evenly distributed when they fall on the ground, reduce material accumulation and adhesion, ensure better fluidity, and reduce jams.
