FIELD: agricultural engineering. SUBSTANCE: drill has hopper-feeder 1, housing 2, conveyor 3 in form of two cylindrical drums inclined relative to horizon, drum angle adjuster 4, seed tube funnel 5 and hinge support 6. Drums 3 are made in form of screws with thread 7 of definite pitch and size. Right-hand thread is cut on one of drums and left-hand thread, on the other. Hopper-feeder 1 is located at the bottom, and intake funnel 5 of seed tube, at top of drill. Drums 3 are mounted on parallel axes lying in one plane. Drive 7 is made for rotating the drums in opposite directions. Drums 3 are installed with inclination relative to horizon which can be changed by means of drum angle adjuster 4. Threaded grooves 8 of drums in static (initial) positions of drill are aligned to form cells at place of their mating over entire mouth of inter drum space. Distance between cells is equal to pitch of threaded groove. EFFECT: enlarged operating capabilities. 1 dwg |
