Abstract

A sowing machine comprises a frame body (2), whereon a hopper (5) with a seed-metering machine is arranged, a storey leg (3) connected via a feeding pipeline with a funnel (4) on bottom of the hopper and arranged under the hopper (5). The utility model is characterized in that the hopper (5) is constituted of a seed-box and a fertilizer hopper, with the two arranged in a parallel and interval manner and associated via the feeding pipeline arranged on the bottom with the double-channel storey leg (3) on the frame body (2). Compared with the prior art, the utility model not only has the advantages of scientific and reasonable structure, but also is capable of carrying out sowing and fertilizing synchronously, changing the row distance via the adjustment of seed-metering rotation speed.

Description

A kind of sower

(1) technical field

The utility model relates to a kind of farm machinery, relates to a kind of sower specifically.

(2) background technology

The sower of prior art exists a common defective, i.e. its each corresponding hopper that is used to hold seed of an animal-drawn seed plough leg, and an animal-drawn seed plough leg is single cavity configuration, can not make seed and fertilizer by sower disposablely finish sowing, the operation of applying fertilizer.If stir disposable sowing with seed and fertilizer are common, not only can have influence on kind, the uniformity of fertile sowing, the accident that seedling burns also very easily takes place.

In addition, because the seeding rotating speed of seeding unit mostly is non-adjustable section type structure in the prior art, the spacing in the rows that is its plant of sowing is constant relatively, and this just makes that the accommodation of sower is limited, and the sower that for example is used to sow wheat just can not be used to sow peanut and corn.

(3) summary of the invention

The purpose of this utility model provides a kind of structure more scientific and reasonable with regard to being to overcome above-mentioned weak point of the prior art, not only has sowing, applies fertilizer and carry out function synchronously, and can realize the sower that spacing in the rows changes by the adjusting of seeding rotating speed.

The purpose of this utility model can realize by following measure:

Sower of the present utility model comprises Rack Body, be installed on the Rack Body its and be provided with the hopper of seeding unit, and an animal-drawn seed plough leg that is positioned at hopper below and is connected with the funnel of feed hopper bottom setting by feeding pipe, described hopper by side by side, the seed-box and the fertilizer can of setting at interval form; Described seed-box and fertilizer can combine with two-chamber an animal-drawn seed plough leg on being installed in Rack Body by the feeding pipe that is arranged on its bottom respectively.

For adapting to no-tillage ground requirement of seeding, the utility model is provided with a weeder at the place, centre position of Rack Body front end.

For adapting to the Different Crop requirement of seeding, the hopper described in the utility model is divided into seed-box and fertilizer can by the plug-in dividing plate.

Why the power transmission shaft that is used to drive seeding unit in the utility model adopts by driven sprocket, the chain drive-belt that is installed in its axle head, is installed in timing chain wheels (being made up of the sprocket wheel that a plurality of diameters are different) and the drive sprocket structure combining mode that is installed in away on the wheel shaft on the jackshaft, and its purpose is exactly to realize that by changing the seeding rotating speed spacing in the rows changes.

Because the entire body formula seed-box (hopper) with traditional structure in the utility model changes into side by side, mutual many body structures of isolating, and the mode (being that per two adjacent seed-box and fertilizer cans are a group) that adopts seed-box and fertilizer can be provided with at interval, and below per two adjacent seed-boxes and fertilizer can, combine with a two-chamber an animal-drawn seed plough leg (an animal-drawn seed plough leg of duplex structure) on being installed in Rack Body by seed transport tube and fertilizer carrier pipe respectively, thereby not only realized disposable kind, the fertile parallel purpose of broadcasting and not covering has mutually down also fundamentally solved in the prior art because of planting, fertilizer covers and the problem of easily generation burning seedling mutually.

Use planting with sowing machine of the present utility model need not apply seed manure and its line-spacing closeer crops---during as wheat, the plug-in dividing plate in the hopper can be extracted out, remove three two-chamber an animal-drawn seed plough legs simultaneously, change six traditional single chamber an animal-drawn seed plough legs and get final product.

(5) embodiment

The utility model is further described below with reference to embodiment (accompanying drawing):

As shown in Figure 1, sower of the present utility model comprise its rear portion have about the Rack Body 2 of two travelling wheels 13, be installed on the Rack Body 2 its and be provided with the hopper 5 of seeding unit, and an animal-drawn seed plough leg 3 that is positioned at hopper 5 belows and is connected with the funnel 4 of feed hopper bottom setting by feeding pipe; Described hopper 5 by side by side, the seed-box and the fertilizer can that are provided with at interval form; More specifically say, described hopper 5 is divided into three seed-boxes and three fertilizer cans by plug-in dividing plate 6, be that per two adjacent seed-box and fertilizer cans are one group, and below per two adjacent seed-boxes and fertilizer can, combine with a two-chamber an animal-drawn seed plough leg 3 (shown in Figure 3) on being installed in Rack Body 2 by seed transport tube and fertilizer carrier pipe respectively as Fig. 2; For adapting to no-tillage ground requirement of seeding, the utility model is provided with a weeder 1 (Fig. 4 is shown in Figure 5) at the place, centre position of Rack Body 2 front ends; Driven sprocket 11, the chain drive-belt 14 of the power transmission shaft 12 that is used to drive seeding unit in the utility model by being installed in its axle head, the timing chain wheels 9 (being made up of the sprocket wheel that a plurality of diameters are different) that are installed on the jackshaft 8 combine with drive sprocket 10 on being installed in away wheel shaft 7.

Claims

1, a kind of sower, it comprises Rack Body (2), be installed on the Rack Body (2) its and be provided with the hopper (5) of seeding unit, and be positioned at hopper (5) below and an animal-drawn seed plough leg (3) that the funnel (4) that is provided with by feeding pipe and feed hopper bottom is connected, it is characterized in that: described hopper (5) by side by side, the seed-box and the fertilizer can of setting at interval form; Described seed-box and fertilizer can combine with two-chamber an animal-drawn seed plough leg (3) on being installed in Rack Body (2) by the feeding pipe that is arranged on its bottom respectively.
