Abstract

The utility model relates to the technical field of agricultural machinery, and particularly relates to a seed distribution device capable of sowing various crops. Most of the existing agricultural machines for sowing have the problems of few functions, simple sowing crop, complex structural design, incomplete functions and the like. The seed distribution device capable of sowing various crops disclosed by the utility model is composed of a fixed frame, a seed box, a seed material box, a seed distribution wheel, a transmission wheel and a transmission shaft; the transmission shaft is assembled on the fixed frame, and the transmission wheel and the seed distribution wheel are installed at the both ends of the transmission shaft respectively; the seed box is installed on a fixed plate on the side surface of the fixed frame; the seed box is connected with the seed material box, and a discharge port below the seed box is matched with the outer circumferential arc surface of the seed distribution wheel; concave pits are uniformly distributed on the outer arc surface of the seed distribution wheel; and a plant distance standard hole-sowing protection belt is wrapped on the outer circumferential surface of the seed distribution wheel. The seed distribution device capable of sowing various crops disclosed by the utility model is simple and convenient to operate; and the concave pits corresponding to different crop plant distances are formed on each seed distribution wheel, and an operator can achieve the purpose of adjusting the plant distances only by replacing the seed distribution wheel, thus realizing multiple purposes.

Description

Can broadcast the seed-distributing device of various crop

Technical field

The utility model relates to the farm machinery technical field, specifically a kind of seed-distributing device of broadcasting various crop.

Background technology

The problems such as existing sowing class farm machinery exists function less mostly on the market, and the sowing crop is single, because the to some extent difference such as the spacing in the rows of different crops, a general sowing farm implements can only be sowed a kind of crops, has the defectives such as the unit availability is lower.Patent No. ZL 200920268856.1 disclosed a kind of sowers of broadcasting various crop can be sowed multiple kinds of crops although solved same sower, complex structural designs, and the operation more complicated, function is still incomplete.

Summary of the invention

The purpose of this utility model provides a kind of seed-distributing device of broadcasting various crop, has overcome the defective of prior art, and is easy and simple to handle, a tractor serves several purposes.

The technical solution of the utility model is: divide thumb wheel, drive, power transmission shaft to form by fixed mount, seed box, kind hopper, seed kind; On fixed mount, power transmission shaft passes fixed mount to power transmission shaft by one group of bearing assemble, and drive is housed respectively at two ends and the seed kind is divided thumb wheel, and fastening by locking nut; The fixed mount side is provided with one group of fixed head, and seed box on fixed head, between fixed head, is set with back-moving spring by bolts assemblies on the bolt; Seed box is communicated with the kind magazine by the conveying flexible pipe, and the discharging opening of seed box below divides the excircle cambered surface of thumb wheel to cooperate with the seed kind; The seed kind is divided on the thumb wheel exterior arc surface and is evenly equipped with pit; Spacing in the rows standard bunch planting protecting band is equipped with at seed box discharging opening place, and spacing in the rows standard bunch planting protecting band is wrapped in the seed kind and divides on the outer circumference surface of thumb wheel; Spacing in the rows standard bunch planting protecting band below has kind of a material outlet.

The utility model has the advantages that: easy and simple to handle, the pit that each seed kind divides thumb wheel to be provided with corresponding Different Crop spacing in the rows, the operator only needs to divide thumb wheel by changing the seed kind, can reach the purpose of adjusting spacing in the rows, realize a tractor serves several purposes, significantly improved the availability of sower.The utility model both can use separately, also can organize the unit more and assemble and be installed on the sower, carried out the large tracts of land sowing.

Embodiment

Among the figure: 1, fixed mount, 2, seed box, 3, plant hopper, 4, the conveying flexible pipe, 5, the seed kind divides thumb wheel, 6, fixed head, 7, spacing in the rows standard bunch planting protecting band, 8, power transmission shaft, 9, drive.

Embodiment 1

From Fig. 1---Fig. 2 as can be known, the utility model by fixed mount 1, seed box 2, plant hopper 3, the seed kind divides thumb wheel 5, power transmission shaft 8, drive 9 to form; Fixed mount 1 and kind hopper 3 are assemblied on the sower, and fixed mount 1 is positioned at the furrow plough rear; On fixed mount 1, power transmission shaft 8 passes fixed mount 1 to power transmission shaft 8 by two bearing assembles, and drive 9 is housed respectively at two ends and the seed kind is divided thumb wheel 5, and fastening by locking nut; Drive 9 is connected with the running gear of sower by chain or driving-belt; Fixed mount 1 side is provided with two fixed heads 6, and seed box 2 passes through two parallel bolts assemblies on fixed head 6, and between fixed head 6, is set with back-moving spring on the bolt, and seed box 2 can move along two bolts; Seed box 2 is communicated with kind magazine 3 by conveying flexible pipe 4, and the discharging opening of seed box 2 belows divides the excircle cambered surface of thumb wheel 5 to cooperate with the seed kind; Under the effect of back-moving spring, seed box 2 is close to the seed kind and divides on the thumb wheel 5; The seed kind divides thumb wheel 5 to be divided into a plurality of models, and the seed kind of each model is divided on thumb wheel 5 exterior arc surfaces, according to the Plants of institute's cloth kind apart from being evenly equipped with a plurality of pits; Seed box 2 discharging opening places have mounted spacing in the rows standard bunch planting protecting band 7, and spacing in the rows standard bunch planting protecting band 7 is wrapped in the seed kind and divides on the outer circumference surface of thumb wheel 5; Spacing in the rows standard bunch planting protecting band 7 belows have kind of a material outlet.

During the utility model work, the seed kind of broadcasting is placed in kind of the hopper 3; Because the spacing in the rows that different crops require is different, selects and assemble corresponding seed kind and divide thumb wheel 5.The seed kind enters seed box 2 through conveying flexible pipe 4, drives drive 9, power transmission shaft 8 and seed kind by chain or conveyer belt when sower is advanced and divides thumb wheel 5 to rotate, and enters the seed kind and divides thumb wheel 5 pits interior seed kind, divides thumb wheel 5 to rotate with the seed kind and is taken out of seed box 2; Spacing in the rows standard bunch planting protecting band 7 can prevent that the seed kind from dividing thumb wheel 5 to plant material in rotation process and dropping in advance, when the seed kind is divided the kind material outlet that the pit of thumb wheel 5 turns to spacing in the rows standard bunch planting protecting band 7 belows, plants material and falls into soil, guarantees the crops spacing in the rows.

The utility model both can assemble separately use, also can be installed on the sower organizing the line-spacing of unit according to crop more, carried out the large tracts of land sowing.
