Description

A kind of towed planter

Technical field

This utility model relates to field of agricultural machinery, particularly relates 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 to save crop resource.The point multicast function imperfection of existing planter, often occurs disseminating, uneven sowing, does not sows and damage the phenomenon of seed, and the program request structure excessively complexity of existing planter causes, and seeder structure is the hugest is not suitable for the sowing of little area.

Utility model content

A purpose of the present utility model is to overcome the problems referred to above to provide a kind of towed planter realizing a multicast function.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of towed planter, dial assemblies including rotating shaft, several rotations being connected to side by side in rotating shaft, be connected to the road wheel that the hopper on assembly is dialled in rotation and drive shaft rotates and the bogie dialling assembly for installing rotation, described rotation dial assembly include rotation dial chamber and rotation pulling part ( 13 ), described rotation is dialled chamber and by barrier plate and is positioned at the non-enclosed cavity body structure that the side shield of barrier plate both sides cooperatively forms, 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 is transferred to from seed export by the seed being dialled chamber by the entrance rotation of seed entrance, and 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 the rotation being arranged on rotation group chamber is dialled at termination, and 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；Described rotation is dialled at termination, 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, the seed being positioned on plectrum departs under gravity from plectrum successively, 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, i.e. move to seed export in the unrestriced mode of dialling of freely revolving, dial at termination 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, rather than be that sequencing drops out successively with the form of disseminating.For 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 all seeds that same plectrum is stirred be one group with the seed of not determined number, and often group seed is the most linearly sowed, make the seed that previous plectrum and later plectrum stirred does not has certain spacing, presents rambling effect.

As preferably, the corresponding central angle of described seed export is θ, and respective radius is R , then θ π R ≥ 180a ； a It 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 inward flange of described upper stop part and lower stop part forms the gap less than seed size with the end of plectrum.

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 occurs, and the base of described anti-nip forms the gap more than or equal to seed size with the end of plectrum.

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 being positioned at rotation pulling part one or both sides, and the flitch inwall connected side shield 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 to turn hole outside aixs cylinder portion protruding side baffle plate.

As preferably, described aixs cylinder portion connects has bearing, described side shield to be provided with the bearing installation room for installing bearing.

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

The beneficial effects of the utility model: this utility model can be effectively improved the program request effect of seed, it is to avoid broadcast leakage occurs, the situation such as disseminates, and be prevented from card type and damage seed.
