Description

Seed sower

Technical field

The present invention relates to field of agricultural machinery, particularly relate to a kind of seed sower rotating program request.

Background technology

Seed sower is agricultural machine indispensable in agriculture production, needs program request single seed in the plantation for part crop, and one is that quantitatively sowing is easy to growth, and two is save crop resource. The point multicast function of existing seed sower is imperfect, often occurs disseminating, uneven sowing, the phenomenon of not sowing and damage seed, and the program request structure of existing seed sower too complexity cause that seed sower structure is too huge is not suitable for small area sowing.

Summary of the invention

It is an object of the invention to overcome the problems referred to above and a kind of seed sower realizing a multicast function is provided.

The above-mentioned technical purpose of the present invention is achieved by the following technical programs: seed sower, comprise revolve dial assembly, described in revolve dial assembly comprise

Described revolving dials termination place, freely revolves, according to unrestricted, the mode of dialling, and starting point is arranged on seed when starting to fall.

Described revolving lifts beginning place and refers to the position left after plectrum completes seed adjustment and revolve and dial chamber initial contact seed, revolve lift the beginning place, action of gravity suffered by seed is on plectrum, with revolving, pulling part is formed centrally moment of resistance, act on that being revolved by seed after the moment of torsion revolving on pulling part overcomes this moment of resistance drags on and revolve and dial in chamber, when plectrum turns to vertex, the seed being positioned on plectrum departs from successively under gravity from plectrum, along with being rotated further, seed falls rotator after departing from completely and the non-of a front plectrum is revolved on the face of dialling, seed is under gravity with rotator and a front plectrum, namely move to seed export in the unrestricted mode of dialling of freely revolving, revolving group termination place, the all seeds stirred by same plectrum, under gravity to fall out from seed export with the freely falling body mode of rotator inertia simultaneously, complete seed program request, but not be that sequencing falls out successively with the form of disseminating. from sowing effect, all seeds that same plectrum is stirred can be intensively deposited in together by program request, the seed that a front plectrum and a rear plectrum are stirred has certain spacing, disseminate, it is that all seeds stirred by same plectrum are taking the seed of not determined number as one group, and often organize seed and linearly sow at certain intervals, what make the seed that a front plectrum and a rear plectrum stir does not have certain spacing, presents rambling effect.

As preferably, the corresponding central angle of described seed export is ��, respective radius is R, then �� R >=180a; A is critical constants, is freely revolve, according to unrestricted, the mode of dialling, the theoretical arc length corresponding to seed export when seed has just fallen.

As preferably, the corresponding central angle �� size of described seed export is 5 ��ܦ� < 90 ��.

As preferably, the preglabellar field of described barrier plate and plectrum end form the gap being less than seed size, and described barrier plate comprises that preventing dishes out seed when revolving and dial revolves the upper stop part dialling chamber and prevent seed from entering, in the non-mode of dialling of revolving, the lower stop part revolving and dialling in chamber.

As preferably, described in revolve the anti-pinch district dialled and be provided with in chamber and prevent plectrum from being dragged on from seed entrance by seed and revolving and occur folder to plant with the end of upper stop part when dialling in chamber.

As preferably, the zero position in described anti-pinch district is seed ingress, the position at place when its stop bit is set to the most significant digit point revolving group chamber or seed departs from from plectrum or departs from completely.

As preferably, described in revolve the gap that the two sides of pulling part are formed with left and right side shield respectively and be less than seed size.

As preferably, the front of described seed entrance is provided with the gate that control seed enters seed entry number.

As preferably, described seed entrance is connected with the material storing cavity depositing seed, it is provided with feeding zone revolving of seed ingress between face, pulling part one or both sides and material storing cavity.

The useful effect of the present invention: the present invention can improve the program request effect of seed effectively, avoids situations such as broadcast leakage occurring, disseminate, and card kind can be prevented and damage seed.
