Abstract

The utility model provides a disc harrow device which is composed of a hanging frame, a beam, a mud scraping device, a disc harrow unit, a harrow frame and a notch harrow unit. The disc harrow device is characterized in that the hanging frame is installed on the beam, the mud scraping device and the disc harrow unit are installed on the lower right position of the harrow frame, the notch harrow unit is installed on the lower front-left position of the harrow frame, and an included angle between the disc harrow unit and the notch harrow unit is 30 degrees. The harrow unit is under action of a traction power during working, disc harrow blades roll and cut into soil under the action of gravity and soil counter-force at a preset harrow depth, and the harrow unit can finish the work of cutting the soil, cutting weeds and turning at the same time due to the action of a declination angle of the harrow blades. The disc harrow device is simple in structure, high in working profit rate, low in cost, safe and reliable.

Description

A kind of disk harrow device

Technical field

The utility model relates to a kind of disk harrow device, belongs to agricultural machinery technological field.

Background technology

In agricultural production, scarification equipment mainly contains mouldboard plow, rotovator, disk harrow etc.The operations such as disk harrow is raked the soil level because once completing, the crop cover chopping is buried, soil subsoiling is smooth obtain extensive use.Yet, traditional disk harrow is raked the soil level after usually can only being used for ploughing, not only transaction capabilities is single, also often too small because of the blade drift angle, additional mass is not enough, operating speed reaches the factors such as blade wearing and tearing soon, causes not enough or the inconsistent and earth's surface unequal phenomenon of the degree of depth of raking the soil level to produce.In the situation that soil is sticking heavy, the blade drift angle is excessive, clean-up scraper and blade gap too small (fix), weeds too much, operating speed is excessively slow, has also that blade stops up, resistance increases, and then cause operation quality unstable also under the degradation problem.Therefore, the design a kind of simple in structure, with low cost, Novel disc rake device that easy to adjust, transaction capabilities is stable is very necessary.

The utility model content

For addressing the above problem, the purpose of this utility model provides a kind of disk harrow device very easily just in order to solve above-mentioned the deficiencies in the prior art.

For addressing the above problem, the utility model is achieved through the following technical solutions:

a kind of disk harrow device, by hanger bracket 1, crossbeam 2, mud-scraping apparatus 3, disk harrow group 4, harrow frame 5, breach rake group 6 forms, it is characterized in that: described hanger bracket is arranged on crossbeam, mud-scraping apparatus and disk harrow group are arranged on the lower right of harrow frame, breach rake group is arranged on the left front below of harrow frame, angle between described disk harrow group and breach rake group is 30 degree, under rake the soil level the effect of unit at traction power in when work, disc is subjected to the action edge rolling limit incision soil of gravity and soil counter-force and reaches predetermined rake dark, effect due to the blade drift angle, the rake group has been completed cutting soil simultaneously, cut off weeds and the work of turning over button.

The beneficial effects of the utility model are: a kind of disk harrow device, simple in structure, work beneficial rate high, with low cost, safe and reliable.

Description of drawings

Fig. 1 is a kind of disk harrow device of the utility model schematic diagram.

Embodiment

as shown in Figure 1, a kind of disk harrow device, by hanger bracket 1, crossbeam 2, mud-scraping apparatus 3, disk harrow group 4, harrow frame 5, breach rake group 6 forms, it is characterized in that: described hanger bracket is arranged on crossbeam, mud-scraping apparatus and disk harrow group are arranged on the lower right of harrow frame, breach rake group is arranged on the left front below of harrow frame, under rake the soil level the effect of unit at traction power in when work, disc is subjected to the action edge rolling limit incision soil of gravity and soil counter-force and reaches predetermined rake dark, effect due to the blade drift angle, the rake group has been completed cutting soil simultaneously, cut off weeds and the work of turning over button.

Below disclose the utility model with better enforcement, so it is not to limit the utility model, all take to be equal to replace or technical scheme that equivalent transformation obtains, all drop in protection domain of the present utility model.

Claims

1. disk harrow device, formed by hanger bracket, crossbeam, mud-scraping apparatus, disk harrow group, harrow frame, breach rake group, it is characterized in that: described hanger bracket is arranged on crossbeam, mud-scraping apparatus and disk harrow group are arranged on the lower right of harrow frame, and breach rake group is arranged on the left front below of harrow frame.

2. a kind of disk harrow device according to claim 1 is characterized in that: the angle between described disk harrow group and breach rake group is 30 degree.
