Cylindrical indent adjustable forced seed discharging device

Abstract

The invention discloses a cylindrical indent adjustable forced seed discharging device and belongs to agricultural machinery. A seed box, a driving motor, a seed guide pipe, rail rods and lead screws are respectively arranged on a device frame, a plate seat is mounted on the rail rods and the lead screws in a sleeving mode, a bottom plate is fixedly arranged on the plate seat, a driving shaft with a supporting driving wheel and a driving gear and a supporting shaft with a supporting follower wheel are respectively and rotatably arranged on the bottom plate through a shaft seat A and a shaft seat B, a cylindrical indent seed filling and discharging wheel with N annular grooves is rotatably supported and mounted on the supporting driving wheel and the supporting follower wheel, indent holes with different hole diameters are formed in the wheel wall of the cylindrical indent seed filling and discharging wheel, a forced seed discharging roller and a driven gear are rotatably mounted on the bottom plate through a bracket, a driving belt is mounted on the driving gear and the driven gear in a sleeving mode, and an arc-shaped seed protecting plate is fixedly arranged on the bottom plate and outside the lower side of the cylindrical indent seed filling and discharging wheel. The same device can be used for sowing seeds with different sizes, and the device is unique in structure, high in generalization degree and wide in application range.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a seed arrangement device. Background technique [0002] The size of the filling sockets on the existing socket roller type seed metering device and the scooping spoon on the spoon wheel type seed metering device cannot be adjusted and changed on a single seed metering device, so the adaptability to seeds is poor, and the seed grains If the size is large, it cannot be filled into the socket, or the seed spoon cannot be scooped in, resulting in missed sowing holes; the seed size is small, and the number of seeds filled in the socket or scooped by the seed spoon will increase, resulting in reseeding and seed waste. Sowing accuracy decreased. The above-mentioned problems have also caused that the same socket-hole roller type seed meter or spoon wheel type seed meter cannot be used for the sowing operation of different varieties of crop seeds, and the use range is narrow and the use ef...

Problems solved by technology

[0002] The size of the filling sockets on the existing socket roller type seed metering device and the scooping spoon on the spoon wheel type seed metering device cannot be adjusted and changed on a single seed metering device, so the adaptability to seeds is poor, and the seed grains If the size is large, it cannot be filled into the socket, or the seed spoon cannot be scooped in, resulting in missed sowing holes; the seed size is small, and the number of seeds filled in the socket or scooped by the seed spoon will increase, resulting in reseeding and seed waste. Sowing accuracy drops

The above problems have also resulted in the fact that the same socket-hole roller seed meter or spoon wheel seed meter cannot be used for sowing seeds of different varieties of crops, and the use range is narrow and the use efficiency is low.

In addition, the seed metering method of the current seed metering device mostly uses the self-weight and centrifugal force of the seeds as the power to complete the seed discharge from the socket or the seed spoon, which is easy to cause the seeds to be stuck and cause the failure of the seeds to be discharged.
