Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a watermelon seed planter. Background technique [0002] During the sowing process of watermelon, the sower needs to use a hoe to dig a hole in the land, and then sprinkle a few watermelon seeds in the dug hole, and then backfill the soil dug out of the hole into the hole to bury the seeds ; During the whole sowing process, the sower needs to bend over constantly, and the sower will feel backache after finishing the sowing, and the labor intensity is high during the whole process. [0003] In order to solve the above problems, the patent document with the application number CN201510452967.8 discloses a planter, including a frame, a push handle and a pair of wheels are installed on the frame, and a material cylinder is arranged between the two wheels, and the material cylinder is a circle. Cylindrical, the barrel is fixedly connected to two wheels and coaxially arranged, and...
