Description

A kind of towed planter

Technical field

The present invention relates to field of agricultural machinery more particularly to a kind of towed planters.

Background technique

Planter is indispensable agricultural machinery in agricultural production, for needing program request single in the plantation of part crop Seed, first is that quantitative sowing is easy to grow, second is that saving crop resource.The point multicast function of existing planter is not perfect, often Appearance disseminates, uneven sowing, the phenomenon that not sowing and damaging seed, and the program request structure excessively complexity of existing planter is led Cause the excessively huge unsuitable small area sowing of seeder structure.

Summary of the invention

One purpose of the utility model is that the above problem is overcome to provide a kind of towed planter for realizing some multicast functions.

Above-mentioned technical purpose of the invention has the technical scheme that a kind of towed planter, packet Include shaft, component, the hopper being connected on rotation group component and drive shaft rotation are dialled in several rotations being connected in shaft side by side Traveling wheel, a non-enclosed cavity body structure being cooperatively formed by side baffle and barrier plate of chamber is dialled in the rotation, for accommodating rotation Pulling part；The rotation pulling part setting is dialled in chamber in the rotation, is driven its rotation that will enter rotation by seed entrance using shaft and is dialled chamber Seed from seed export transfer to, including rotary body and a number of plectrum being evenly arranged on the rotary body circumferential surface； Seed entrance is formed by left and right sides baffle fit, and the rotation group section start that chamber is dialled in rotation is arranged in；Seed export, by left and right side baffle It cooperatively forms, rotation is set and is dialled at the rotation group termination of chamber；The seed entrance and seed export set up separately in the two sides of shaft, described The lower section that rotation dials the side of component direction of advance and dials component close to rotation is arranged in seed export.

Preferably, section start is dialled in the rotation, the rotation is set and dials the non-highest site of chamber, and revolves the seed adjustment period of the day from 11 p.m. to 1 a.m to have The moment of resistance；The rotation is dialled at termination, freely revolves the mode of dialling according to unrestricted, starting point setting is when seed starts to fall.

The rotation dials after section start refers to plectrum completion seed adjustment and leaves the position that chamber initial contact seed is dialled in rotation；It is dialled in rotation Section start, the torsion that is centrally formed the moment of resistance, acts on rotation pulling part on of the gravity suffered by seed on plectrum, with rotation pulling part Square overcomes to be dialled intracavitary after this moment of resistance by seed rotation rotation of dragging on, and when plectrum turns to highest point, the seed on plectrum exists It is detached from successively from plectrum under gravity, with continuing to rotate, seed falls on rotary body and previous plectrum after completely disengaging Non- rotation dial on face, seed under the effect of gravity with rotary body and previous plectrum, i.e., in a manner of unrestricted freely revolve group to Seed export is mobile, dials at termination in rotation, all seeds stirred by the same plectrum, under the effect of gravity with rotation The freely falling body mode of inertia is dropped out from seed export simultaneously, completes seed program request, rather than in the form of disseminating in sequencing according to It is secondary to drop out.For sowing effect, all seeds that program request can be stirred the same plectrum are intensively stacked upon, preceding The seed that one plectrum and the latter plectrum are stirred has certain spacing, and disseminates, and is to be stirred the same plectrum All seeds are with the seed of indefinite quantity for one group, and every group of seed is linearly sowed at certain intervals, so that previous The not certain spacing for the seed that a plectrum and the latter plectrum are stirred, is presented rambling effect.

Preferably, the correspondence central angle of the seed export is θ, respective radius R, then θ π R >=180a；A is critical Constant is freely to revolve the mode of dialling according to unrestricted, the theoretical arc length corresponding to seed export when seed just falls completion.

Preferably, the barrier plate includes preventing from that seed is dished out when rotation is dialled to revolve to dial the upper blocking portion of chamber and prevent from planting Son enters rotation in such a way that non-rotation is dialled and dials intracavitary lower blocking portion, the end of the inward flange and plectrum of the upper blocking portion and lower blocking portion The gap that portion is formed is less than seed size.

Preferably, the seed entrance be equipped with prevent plectrum by seed from seed entrance drag on rotation dial it is intracavitary when with upper resistance The anti-clip area of folder kind occurs for the end of stopper, and the bottom edge of the anti-clip area and the end of plectrum form and be greater than or equal to seed size Gap.

Preferably, the hopper by the flitch that is connected on side baffle with being combined into, formed for store seed and with The storage cavity of seed entrance connection.

Preferably, the seed inlet is equipped with the feeding zone for being located at rotation pulling part one or both sides, it is located in feeding zone Flitch inner wall side baffle inner wall connected to it form difference in height.

Preferably, the rotation pulling part is equipped with to aixs cylinder on the outside of the protrusion side baffle of two sides and for connecting shaft Portion, the aixs cylinder portion are equipped with the sets of holes for being socketed shaft, and the side baffle, which is equipped with, stretches out aixs cylinder portion on the outside of side baffle Turn hole.

Preferably, the aixs cylinder portion is connected with bearing, the side baffle is equipped with the bearing for installing bearing and installs Room.

Preferably, being additionally provided with the pull rod for pulling its movement on the bogie.

Beneficial effects of the present invention: the present invention can effectively improve the program request effect of seed, avoid the occurrence of broadcast leakage, disseminate Situations such as, and card type and damage seed can be prevented.
