Abstract
Description
Technical Field
[0001] The utility model relates to a sowing device, in particular to an agricultural sowing device. Background Art
[0002] Most of the existing seed drills are large-scale seed drills, which are suitable for sowing large areas of land. However, for non-plain areas such as mountains, large seed drills are often difficult to enter the fields, so they are not feasible. Therefore, small handheld seed drills are needed.
[0003] After searching, the patent with announcement number CN219478504U discloses a seeder, which rotates the discharge wheel and drives the feed wheel to rotate through the transmission mechanism. The seeds leaked from the bottom of the hopper fall into the discharge groove of the discharge wheel after the feed groove of the feed wheel rotates. The discharge wheel then sprinkles the seeds from the discharge groove to the ground. As the discharge wheel continues to rotate, multiple seeds are sprinkled on the ground at equal intervals; if the seed type is changed, the transmission mechanism is disassembled and replaced with another transmission mechanism with a different transmission ratio, so that the transmission ratio of the discharge wheel and the feed wheel is changed. When the discharge wheel keeps rotating at the original speed, the rotation speed of the feed wheel changes, and the number of seeds falling from the feed wheel to the discharge wheel changes, thereby changing the spacing of the seeds sprinkled to the ground by the discharge wheel.
[0004] Although the above scheme can change the transmission ratio of the discharge wheel and the feed wheel by replacing the transmission mechanism with a different transmission ratio to change the seed spacing during sowing, replacing the transmission mechanism is relatively cumbersome, and a single gear set, pulley set and sprocket set often only has one transmission ratio, which cannot meet the needs of users and needs to be improved.

[0009] As a further solution of the present invention: a plurality of second belt grooves are formed on the outer peripheral wall of the tensioning pulley, and the second belt grooves are aligned one by one with the first belt grooves on the first pagoda pulley.
