Description
Technical field
The utility model relates to agricultural mechanical field, relates in particular to the structural improvement of rice seeder, is a kind of seeding quantity governor motion of rice seeder.
Background technology
Existing rice seeder has replaced the by artificial seeding, and when the driving sower travelled, the paddy in the hopper was sprinkling upon in the arable land from tremie pipe.This seeding machinery form also is applicable to other crops, and as the sowing of rape, wheat, and at home owing to the cultivated area maximum of paddy rice, therefore adopting mechanical planting is the most feasible means.
Traditional sower is to control seeding quantity by the position of regulating hopper below seeding unit, paddy is directly discharged from tremie pipe, because the hopper below is provided with feed opening, in the time that seeding quantity will be adjusted, must adjust the openings of sizes of feed opening one by one, in order to avoid seeding quantity is unbalanced, but such adjustment one by one is very inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of seeding quantity governor motion of rice seeder, can unify synchronous adjustment to the seeding quantity of most feed openings of a sower.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of seeding quantity governor motion of rice seeder, be improvement structure to the poking device of rice seeder, rice seeder is by frame, frame is provided with motor, transmission mechanism and hopper, hopper is provided with most discharging openings, the discharging opening place is provided with poking device, described poking device is provided with seeding unit, but and drive by the turning cylinder of move left and right, the intrinsic splined shaft of turning cylinder outside cover, splined shaft is provided with most bar axial bonds, the splined shaft outside is arranged with sprocket wheel, the axis hole of sprocket wheel is provided with the corresponding with it axial keyway of most bars, and sprocket wheel is set in the splined shaft outside and circumferentially locatees with it.
By the setting of splined shaft, make transmission mechanism when driving turning cylinder and rotating, splined shaft moves axially about sprocket wheel relatively, reaches to move axially about an action drive power transmission shaft and realize adjusting synchronously the effect of seeding quantity, and it is extremely convenient to operate.
Because turning cylinder is longer, for easy to process, described turning cylinder adopts the two-period form structure, the fixing splined shaft in the junction of two sections turning cylinders.
On the basis of such scheme, in order to adjust seeding quantity, described turning cylinder is provided with most seeding units, seeding unit is located at each discharging opening below of hopper and corresponding one by one, one end of this seeding unit is an optical axis, the other end is the seed wheel of surface band groove, and the two ends of seeding unit are equipped with the limited block of restriction turning cylinder move left and right.When the optical axis alignment discharging opening of seeding unit below, do not have paddy and taken out of from discharging opening, when the seed wheel of seeding unit was aimed at the discharging opening below, paddy was embedded in the groove of seed wheel and takes out of, discharges through tremie pipe.By the position of adjusting seeding unit and discharging opening, thus the size of control seeding quantity.
On the basis of such scheme, manual operation for convenience, the middle part of described turning cylinder is provided with the adjusting spanner.So design does not need to stop after planting to carry out single adjusting promptly can be adjusted to the seeding quantity that needs so that only need move the adjusting spanner in the sowing.
On the basis of such scheme, described transmission mechanism comprises power transmission shaft, reduction box, sprocket wheel and chain, and power transmission shaft is connected with reduction box, and a sprocket wheel is located on the reduction box, by chain and the sprocket wheel interlock that is set on the splined shaft.Concrete, the rotation of motor-driven power transmission shaft drives sprocket rotation on it by reduction box, and by chain drive, another sprocket wheel drives the splined shaft that keyway with it cooperates and rotates, and rotates thereby drive turning cylinder.
The beneficial effects of the utility model are:
The utility model has adopted link gear on sower, make most seeding units on the turning cylinder, by being connected of splined shaft and keyway, can also be in by the sprocket wheel driven rotary relative to chain crop rotation Y-axis to moving, reach most synchronization-moving purposes of seeding unit on the turning cylinder, realize the synchronous adjustment of amount of seed metering, the sowing better effects if.
