Description

Technical Field

[0001] The utility model relates to the technical field of seed sowing, in particular to a wheat sowing device for evenly sowing seeds. Background Art

[0002] Agricultural sowing devices are needed during agricultural planting to facilitate people to use them when sowing and to carry out sowing operations more quickly.

[0003] A Chinese patent discloses an agricultural sowing device for uniform sowing, with the publication number CN213404068U, comprising a bottom plate, a universal wheel fixedly connected to the bottom surface of the bottom plate, a seed box fixedly connected to the middle of the upper surface of the bottom plate, a motor fixedly connected to the other side of the upper surface of the bottom plate, a rotating drum fixedly connected to the output end of the motor, a belt sleeved on the outer surface of the rotating drum, a groove formed on the upper surface of the belt, a discharge port formed inside the seed box, and a box cover movably connected to the top of the seed box via a hinge. The agricultural sowing device for uniform sowing, through the coordinated arrangement of the motor, the rotating drum and the belt, the motor can drive the belt to rotate, through the coordinated arrangement of the groove and the discharge port set on the belt, when the groove and the discharge port are aligned, the seeds can fall into the groove, so that the seeds fall evenly into the land, and through the coordinated arrangement of the plow and the rectangular hole, the seeds can directly fall into the land from the rear.

[0004] However, there are still the following disadvantages: the device uses the grooves on the belt to transport seeds, but the belt has a certain toughness. When there are many seeds in the seed box and the seeds are heavy, the top of the belt will bend downward, so that the top surface of the belt cannot fit the inner wall of the seed box, and the seeds fall between the seed box and the top of the belt, affecting the sowing of the device. To this end, we proposed a wheat sowing device with uniform sowing to solve this problem. Utility Model Content
