Abstract

The utility model relates to a spike-tooth disc combined harrow for harrowing during agricultural production, which can effectively solves the problems of low-speed and bad-effect harrowing. The utility model is structurally characterized in that: spike teeth are arranged on the front and back of a harrow frame, a rotating shaft is arranged in two ends of the harrow frame between the front and the back spike teeth, a disc with gullet is arranged on the rotating shaft, and an erector is arranged in the middle of the harrow frame. The utility model which does not need manual harrow pressing and reduces labor intensity with a novel and unique structure, fast harrowing speed, good effect as well as energy saved can surely contribute much to good harvest.

Description

Spike-tooth disk jointed harrow

One, technical field

The utility model relates to a kind of spike-tooth disk jointed harrow of the usefulness of raking the soil level in agricultural production.

Two, background technology

It is requisite in the agricultural production raking the soil level in the arable land, has many soil blocks (claiming native lump to flog again) after pine is ploughed in special soil, if soil block is not pulverized, the germination and the crop that can have a strong impact on seed grow up, and be also unfavorable in soil moisture conservation.The soil of usefulness rake generally is to adorn a few row's rake teeths (spike-tooth) on the rake frame at present, the disc type that also has that mechanization drives is harrowed, but no matter existing any rake in use all exists the speed of raking the soil level slow, weak effect, need repeatedly walking on ploughing repeatedly, when surperficial soil block is pulverized, again with the compacting of bottom, ground, be unfavorable for the plant root growth, and labour intensity is big, and is time-consuming, and the energy has also been caused very big waste.

Three, utility model content

At the needs of raking the soil level in above-mentioned situation and the agricultural production, the purpose of the utility model just provides a kind of novel spike-tooth disk jointed harrow, can effectively solve the problem of the slow weak effect of speed of raking the soil level in the agricultural production, its technical scheme is, laterally adorn the spike-tooth (being rake teeth) of the usefulness of raking the soil level in rake frame front and rear part, the rake frame is laterally arranged along spike-tooth and in a two ends turning cylinder is housed, and the slewing circle fluted disc is housed, its novel structure uniqueness of the utility model on the turning cylinder, the speed of raking the soil level is fast, usually rake the soil level and want 5 times, the utility model only needs 3 times, and does not need the artificial rake of pressing again, alleviated labour intensity greatly, owing to improved operating efficiency, reduced the number of times of raking the soil level, can save energy 20%, effective, the problem of also having avoided native surperficial bottom to be compacted effectively simultaneously, of the present utility model applying must be made positive contribution for the agricultural high yield.

Four, description of drawings

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is a structure vertical view of the present utility model.

Fig. 3 is a structure of the present utility model left side (right side) end view.

Five, tool ground embodiment

Provide by Fig. 1, Fig. 3, the utility model is to be made of rake frame, spike-tooth and disk, rake frame 1 front and rear part laterally is equipped with spike-tooth 3 respectively, in rake frame 1 two ends of 3 of front and back spike-tooths, turning cylinder 5 is housed, disk 6 (vertically for a plurality of) is housed on the turning cylinder 5, have teeth groove 8 (disk 6 peripheries are dentations) on disk 6 peripheries, crane 2 is equipped with at the middle part on the rake frame 1, spike-tooth 3 is contained on the rake frame 1 by U-shaped screw 7, and turning cylinder 5 is contained on rake frame 1 two ends through bearing 4, and disk 6 is contained between the spike-tooth of front and back.

As required, spike-tooth 3 can be many rows, disk 6 also can be many rows, but spike-tooth 3 is alternate before and after wanting with disk 6, and spike-tooth 3 also can adopt in punching on the rake frame 1 and be contained on the rake frame 3, especially as wooden rake commonly used now, adopting U-shaped screw 7 fixing general rake frames is chase, increase the rake body weight first, second be convenient to loading and unloading and change spike-tooth, firmly.Operating position has no special requirements with existing harrowing equipment, and is convenient, fast, is easy to penetration and promotion.

Claims

1, a kind of spike-tooth disk jointed harrow, be to constitute by rake frame, spike-tooth and disk, it is characterized in that harrowing frame (1) front and rear part spike-tooth (3) laterally is housed respectively, in rake frame (1) two ends between front and back spike-tooth (3) turning cylinder (5) is housed, disk (6) is housed on the turning cylinder (5), has teeth groove (8) on disk (6) periphery.

2, spike-tooth disk jointed harrow according to claim 1 is characterized in that said rake frame (1) is equipped with crane (2) in the middle part of going up.
