Abstract

The invention relates to a delivery mechanism of a seeder, in particular to a hole digging device with adjustable hole depth. The hole digging device comprises a fixed rack, a drive mechanism, a transmission cam group, an adjusting propping block and a driven slide bar, wherein the drive mechanism comprises a fixed gear, a sliding gear and a slider, the fixed gear is rotationally connected onto the fixed rack and meshed with the sliding gear, and the sliding gear is rotationally connected to the slider which is glidingly connected to the fixed rack; the transmission cam group comprises a camshaft, a transmission cam and an adjusting cam, the camshaft is fixedly connected with a shaft of the sliding gear, the transmission cam and the adjusting cam are both fixed on the camshaft, the transmission cam is propped against the driven slide bar above the transmission cam, the driven slide bar is glidingly connected to the fixed rack, the adjusting cam is propped against the adjusting propping block below the adjusting cam, and the adjusting cam is fixed on the fixed rack. The hole digging device capable of changing the hole digging depth is provided to solve the problems that a transmission mechanism of the conventional hole digging mechanism cannot change the maximum travel and the hole depth cannot be adjusted.

Description

technical field [0001] The invention relates to a transmission mechanism of a seeder, in particular to a punching device with adjustable hole depth. Background technique [0002] Seeder is a planting machine that takes crop seeds as the sowing object. The seeder used for a certain type or a certain crop is often named after the type of crop, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. [0003] The planter includes a hole-sowing type, and the hole-sowing type is a planting machine that sows seeds in holes according to a certain row spacing and hole spacing. Each hole can sow one or several seeds, which are called single-seed precision sowing or multi-seed hole sowing. It is mainly used for row crops such as corn, cotton, sugar beet, sunflower, beans, etc. It is also called row crop seeder. Each planter unit can complete the entire operation process of ditching, seeding, soil covering, and suppression. [0004] The hole sowing type seeder ne...
