Description
Technical field
The present invention relates to agricultural mechanical field, be a kind of dibbling type seeding machine for rice, relate in particular to its structural improvement.
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 because seeding unit is all rotating seeding all the time, paddy is directly discharged from tremie pipe, therefore be difficult to control sowing interval and seeding quantity, drive the rotary speed that the sprocket wheel of different size is regulated seeding unit by decelerator, in the seeding process, occur not shortcoming such as spacing of amount of seed metering heterogeneity, seeding easily.
Generally 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, must adjust the openings of sizes of feed opening one by one in the time will adjusting seeding quantity, 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 by this invention is to provide a kind of dibbling type seeding machine for rice, has the sowing interval and stablizes, and can unify the characteristics of adjustment synchronously to the seeding quantity of most feed openings of a sower.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of dibbling type seeding machine for rice, 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, each discharging opening below and tremie pipe UNICOM, the mouth of pipe of tremie pipe is by attacking a vital point mechanism opening or close, wherein
The described mechanism of attacking a vital point comprise coaxial interlock rotation cover plate and latch plate, turn over and dial dialling plate and being installed in cam on the reduction box of latch plate, wherein, cover plate is located at the tremie pipe mouth of pipe, and cover plate and latch plate are fixed, the other end of latch plate is provided with spring, and spring is fixed on the frame; An end of dialling plate is located at the latch plate place, and the other end is located in the rotating range of cam; Cam is circumferentially with most protruding pin, and protruding pin is stirred plate;
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.
The present invention has adopted the novel sowing form of attacking a vital point, owing to be provided with the cover plate that can close or open at the tremie pipe mouth of pipe, controls sowing interval and seeding quantity by cover plate, and is irrelevant with the rotary speed of seeding unit.Its principle is: reduction box drives cam and rotates, and the protruding pin of cam is replaced group plate and made its upset, and the other end of dialling plate promotes latch plate, and cover plate rotates around the axle interlock, opens tremie pipe and sows.When protruding pin and group plate break away from, under the elastic-restoring force of spring, the latch plate momentary reset, cover plate tightly is buckled in and closes tremie pipe on the mouth of pipe.
The present invention makes when driving the turning cylinder rotation by the setting of splined shaft, and splined shaft sprocket shaft relatively reaches an action drive power transmission shaft and moves to traversing, and adjusts the effect of seeding quantity synchronously, and it is extremely convenient to operate.
Because turning cylinder is longer, for easy to process, turning cylinder can be divided into two sections, two sections turning cylinders are fixed by splined shaft.
Described switch-plate shaft is located on the frame, and an end of latch plate is provided with extension spring and is pressed in the top of dialling plate one end, and this end is dialled the below of plate by the limiting plate location that is fixed on the frame.Protruding pin compresses an end of group plate downwards, dials the other end perk of plate, and an end of latch plate is dialled on the plate to be lifted, and cover plate rotates around the axle interlock, thereby makes cover plate with the mouth of pipe take place separating of moment.
On the basis of such scheme, described protruding pin circumferentially evenly distributes along cam.The cam revolution moves equal angular, and protruding pin is just replaced and dialled plate and stir once, thereby cover plate also opens once, and the control sowing at interval thus; Simultaneously, because the degree that cover plate is opened is controlled by latch plate, therefore can accurately control seeding quantity.
On the basis of such scheme, the mouth of pipe of described tremie pipe is provided with downwards, and the mouth of pipe is a diagonal cut joint.The mouth of pipe of tremie pipe is designed to diagonal cut joint, and more effective control sowing position is concentrated paddy and is fallen within a bit.
On the basis of such scheme, 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 seed wheel and optical axis, thus the size of control seeding quantity.
On the basis of such scheme, the middle part of described turning cylinder is provided with the adjusting spanner.So design is regulated the seeding quantity that spanner promptly can be adjusted to be needed so that only need move sowing the time, does not need to stop after planting to carry out single adjusting.
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, connects chain and the sprocket wheel interlock that is set on the splined shaft.Concrete, the rotation of motor-driven power transmission shaft drives cam by reduction box and rotates, and drives the sprocket rotation on it simultaneously, by chain, drives the sprocket rotation that is enclosed within on the splined shaft, rotates thereby drive turning cylinder.
The invention has the beneficial effects as follows:
The present invention is by cam control sowing, and the cam revolution moves equal angular, and protruding pin is replaced group plate and stirred once, and cover plate is opened once, and control is sowed at interval and can accurately be controlled seeding quantity, the sowing of realization dibbling type;
The present invention has adopted link gear, make most seeding units on the turning cylinder, by being connected of splined shaft and sprocket wheel keyway, make turning cylinder in by the sprocket wheel driven rotary relatively the chain crop rotation move axially, reach most purposes that seeding unit is regulated with moved further on the turning cylinder, realize the synchronous adjustment of amount of seed metering, the sowing better effects if.
