Abstract

The invention relates to the field of farm machines and in particular relates to a traction type dibbler. The traction type dibbler comprises a rotation shaft, a plurality of rotary shifting components connected onto the rotary shaft side by side, hoppers connected to the rotary shifting components and travelling wheels for driving the rotation shaft to rotate, wherein a rotary shifting cavity is of a non-sealed cavity structure formed by a side baffle and a barrier plate and used for accommodating a rotary shifting part; the rotary shifting part is arranged in the rotary shifting cavity and is driven to rotate by the rotation shaft so as to shift seeds entering the rotary shifting cavity via a seed inlet out of a seed outlet; the rotary shifting part comprises a rotation body and a plurality of shifting sheets which are evenly distributed at the periphery of the rotation body; the seed inlet and the seed outlet are respectively formed in two sides of the rotation shaft; the seed outlet is formed in one side in a direction of forward motion of the rotary shifting components and is located near the lower parts of the rotary shifting components. The traction type dibbler is capable of preventing the seeds from being stuck and damaged and enabling the seeds to be complete and damage-free in the rotary shifting process; the rotary shifting part rotates smoothly and flexibly, so that the effect of dibbling the seeds is effectively improved.

Description

A kind of towed planter

Technical field

The present invention relates to field of agricultural machinery, particularly relate to a kind of towed planter.

Background technology

Planter is indispensable agricultural machinery in agricultural production, needs single seed of program request in the plantation for part crop, and one is that quantitatively sowing is prone to growth, and two is save crop resource. The point multicast function imperfection of existing planter, often occurs disseminating, uneven sowing, does not sow and damage the phenomenon of seed, and the program request structure excessively complexity of existing planter causes that seeder structure is excessively huge and is not suitable for the sowing of little area.

Summary of the invention

It is an object of the invention to overcome the problems referred to above to provide a kind of towed planter realizing a multicast function.

The above-mentioned technical purpose of the present invention has the technical scheme that a kind of towed planter, dial assembly including rotating shaft, several rotations being connected to side by side in rotating shaft, be connected to the road wheel revolving the hopper dialled on assembly and drive shaft rotation, the non-enclosed cavity body structure that chamber is cooperatively formed is dialled in described rotation by side shield and barrier plate, for accommodating rotation pulling part; Described rotation pulling part is arranged on described rotation and dials in chamber, utilizes rotating shaft to drive it to rotate and dials the seed in chamber from seed export dial-out by entering rotation by seed entrance, including rotary body and a number of plectrum being evenly arranged on described rotary body side face; Seed entrance, is formed by left and right sides baffle fit, and section start is dialled in the rotation being arranged on rotation group chamber; Seed export, is formed by left and right sides baffle fit, and termination place is dialled in the rotation being arranged on rotation group chamber; Described seed entrance and seed export set up the both sides in rotating shaft separately, and described seed export is arranged on rotation and dials the side of assembly direction of advance and dial the lower section of assembly close to rotation.

As preferably, section start is dialled in described rotation, is arranged on described rotation and dials the non-highest order point in chamber, and the rotation seed adjustment period of the day from 11 p.m. to 1 a.m has the moment of resistance; Termination place is dialled in described rotation, freely revolves, according to unrestriced, the mode of dialling, and starting point is arranged on seed when starting to fall.

Described rotation is dialled section start and is referred to that plectrum leaves rotation and dials the position of chamber initial contact seed after completing seed adjustment;Section start is dialled in rotation, action of gravity suffered by seed is on plectrum, with rotation pulling part be centrally formed the moment of resistance, act on rotation of seed rotation being dragged on after the moment of torsion on rotation pulling part overcomes this moment of resistance and dial intracavity, when plectrum turns to peak, it is positioned at the seed on plectrum to depart from successively from plectrum under gravity, along with being rotated further, seed is fallen the non-rotation of rotary body and previous plectrum and is dialled on face after completely disengaging from, seed is under gravity with rotary body and previous plectrum, namely move to seed export in the unrestriced mode of dialling of freely revolving, termination place is dialled in rotation, the all seeds stirred by same plectrum, under gravity to drop out from seed export with the freely falling body mode of rotator inertia simultaneously, complete seed program request, but not be that sequencing drops out successively with the form of disseminating. from sowing effect, all seeds that same plectrum is stirred can be intensively stacked upon by program request, the seed that previous plectrum and later plectrum are stirred has certain spacing, disseminate, be that all seeds stirred by same plectrum are with the seed of not determined number for one group, and often group seed is linearly sowed at certain intervals, what make the seed that previous plectrum and later plectrum stir does not have certain spacing, presents rambling effect.

As preferably, the corresponding central angle of described seed export is ��, and respective radius is R, then �� R >=180a; A is critical constant, is based on unrestriced freely revolving the mode of dialling, the theoretical arc length corresponding to seed export when seed has just fallen.

As preferably, the rotation that includes preventing being dished out by seed when rotation is dialled of described barrier plate is dialled the upper stop part in chamber and prevents from seed from dialling mode with non-rotation entering rotation and dial the lower stop part of intracavity, and the gap that the inward flange of described upper stop part and lower stop part and the end of plectrum are formed is less than seed size.

As preferably, described seed entrance is provided with and prevents from plectrum from being dragged on when intracavity is dialled in rotation from seed entrance by seed with the end of upper stop part the anti-nip of folder kind occurring, and the end of the base of described anti-nip and plectrum forms the gap more than or equal to seed size.

As preferably, described hopper forms with the flitch being connected on side shield, is formed for depositing seed and the storage cavity connected with seed entrance.

As preferably, described seed porch is provided with the feeding zone of rotation pulling part one or both sides, and the connected side shield inwall of flitch inwall being positioned at feeding zone forms difference in height.

As preferably, described rotation pulling part is provided with and protrudes outside side shield and for connection rotating shaft aixs cylinder portion to both sides, and described aixs cylinder portion is provided with the trepanning for being socketed rotating shaft, and described side shield is provided with and makes aixs cylinder portion stretch out to turn hole outside side shield.

As preferably, described aixs cylinder portion is connected to bearing, and described side shield is provided with the bearing installation room for installing bearing.

As preferably, described bogie being additionally provided with the pull bar pulling it to move.

Beneficial effects of the present invention: the present invention can be effectively improved the program request effect of seed, it is to avoid the situation such as broadcast leakage occurs, disseminate, and be prevented from card type and damage seed.
