Description

Hand-held deep-loosening weeding machine

Technical Field

The utility model relates to a dark pine several and weeder especially relate to an agricultural machine that gathers dark pine, weeding as an organic whole.

Background

Subsoilers (e.g., CN 205389342U) are an agricultural implement for plowing soil and generally include a tractor attached to a frame, a furrow plow fixed to the frame for plowing the soil and rollers for supporting the furrow plow. Although the subsoiler with the structure has a simpler structure, the subsoiler does not have power, so that the subsoiler usually needs a large-scale tractor for traction, and is intelligently suitable for large-area leveling and piece-connecting land cultivation. In addition, the furrow plough of the traditional deep scarifier is of a fixed structure, and the roller supports the furrow plough, so the scarification depth is determined, and the angle and the depth of the furrow plough extending into the soil can not be adjusted; therefore, the utility model can not adapt to the cultivation of rugged mountain land. Thirdly, the traditional subsoiler can only plough and loosen the soil generally, but can not crush and smooth the ploughed soil blocks; therefore, the plowing and loosening effects of the soil with high moisture content are not ideal. Fourthly, weeds cannot be removed in the deep scarification process, and the weeds are easy to compete with crops for nutrients, so that the planting effect is influenced.

Disclosure of Invention

In order to overcome the above-mentioned defect that exists among the prior art, the utility model aims at providing a hand-held subsoiling weeder that is suitable for the use of arable land in mountain area, has soil plowing concurrently loose and weeding function, adjustable subsoiling angle and degree of depth.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the weeding machine comprises a chassis, an engine and a gearbox which are fixed on the chassis, a transmission mechanism for connecting the engine and the gearbox, a walking power machine which is fixed on the chassis and is formed by wheels driven by the gearbox, and a weeding mechanism and a subsoiling mechanism which are connected with the walking power machine; the weeding mechanism comprises knife rests fixed on two sides of the gearbox, a rotating shaft supported between the two knife rests, a driving chain wheel fixed on an output shaft of the gearbox, a driven chain wheel and a weeding hob fixed on the rotating shaft, and a chain connecting the driving chain wheel and the driven chain wheel, wherein the subsoiling mechanism comprises a subsoiling plough hinged with the gearbox through a mounting frame, a mounting plate fixed on the gearbox, and a hydraulic cylinder hinged between the mounting plate and the subsoiling plough.

The weeding hob consists of a roller fixed on a rotating shaft, a right rotary cutter distributed on the surface of the roller according to a right rotary spiral line and a left rotary cutter distributed on the surface of the roller according to a left rotary spiral line; the cutting edges of the right rotary knife and the left rotary knife are evenly distributed with arc-shaped saw teeth.

Compared with the prior art, the utility model discloses owing to adopted above-mentioned technical scheme, consequently have following advantage:

1) because the deep loosening mechanism and the weeding mechanism are directly arranged on the walking power machine (such as a walking tractor), the deep loosening plough and the weeding operation can be realized without the traction of a large tractor, and the operation is flexible and mobile; is very suitable for the farmland in mountainous areas.

2) Because the subsoiling mechanism and the weeding mechanism are installed at the same time, the subsoiling plowing and weeding process can be realized by one-time operation, and the operation efficiency is greatly improved.

3) Because the hydraulic cylinder is adopted, the soil-entering angle and the depth of the deep scarification plough can be adjusted through the hydraulic cylinder, and the deep scarification plough can completely adapt to the requirements of uneven cultivated land in mountainous areas.

4) Owing to installed weeding mechanism, consequently left and right helical blade can push the soil that the plough is loose and pile up in soil ditch both sides on the one hand and backfill in the ditch, and on the other hand can also carry out the breakage to the mud piece through setting up the circular-arc sawtooth in helical blade edge department. In addition, the arc-shaped saw teeth at the edge of the spiral blade can cut off weeds, and the grass scraps can be deeply buried in the soil ditch along with backfilled soil, so that the soil fertilizer efficiency is increased.

5) The weeding hob can also play a role of a supporting roller, so that the depth of the deep scarification plough cutting into the soil layer can be limited.
