Abstract

The utility model relates to an arc rotary drilling knife for paddy field cultivator, characterized in that the arc rotary drilling knife comprises a shaft sleeve with a mounting element, wherein the shaft sleeve is provided with a plurality of arc blades. Through employing said technical proposal, the arc rotary drilling knife for paddy field cultivator of the utility model has the advantages of simple structure, less load and reliable performance, which is capable of reliably cultivating in deep soil paddy field, avoiding the paddy field cultivator from sinking or bogging down. The rotary drilling knife drills the soil into small pieces, without destroying soil, and takes great protective function to soil.

Description

Paddyfield plough revolves with arc and digs cutter

Affiliated technical field

The utility model relates to the apparatus on a kind of farm machine, the cutter on particularly a kind of paddyfield plough.

Technical background

People are behind paddy rice harvesting, the rice field is also become the Tian Houzai retaining, the somebody burns the back with grass stalk to go back field or direct returning to farmland before going back the field, not only polluted atmosphere and grass stalk burnt, simultaneously fertilizer also is wasted, direct returning to farmland generally is to go back the field with the mode that Niu Li or people dig at present, and this also field mode farming efficient is low, and labour intensity is big.Also useful now rotovator carries out direct returning to farmland, because directly with field also, rice field, have a lot of grass stalks in the rice field, when rotary tillage, grass stalk will twist to be ploughed on the cutter, can not realize tractor-ploughing straw and the double action of going back the field, and this rotovator only is fit to the more shallow rice field farming of muddy water, and during to the darker rice field farming of muddy water, rotovator can sink or sink, can not carry out farming to the rice field, not reach the purpose of farming.

Summary of the invention

The purpose of this utility model just provides a kind of paddyfield plough simple in structure, dependable performance and revolves with arc and dig cutter, and it can be in dark muddy water Tanaka's reliable farming, avoid paddyfield plough to sink or sink.

The purpose of this utility model is to realize by such technical scheme, it is characterized in that: it includes the axle sleeve of band installed part, and wherein axle sleeve is provided with a plurality of arcuate blades.The utility model is work like this: in the time will carrying out farming to the deep water field, the utility model is installed on the paddyfield plough by installed part, driving axle sleeve by engine rotates, cambered blade also rotates farming earth thereupon simultaneously, curved knife scrapes out little bulk with the earth piece, the contact area of cambered blade and earth obviously increases, and curved knife is reduced the pressure of earth, thereby has prevented paddyfield plough sinking or sagging.

Owing to adopted technique scheme; the utlity model has following simple in structure, the advantage little, dependable performance of loading; it can be in dark muddy water Tanaka's reliable farming; avoid paddyfield plough sinking or sagging; arc digs cutter earth is scraped out little bulk; do not destroy soil, soil has been played good protective action.

Description of drawings

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cutaway view Amplified image of A-A among Fig. 1.

Among the figure: 1. installed part; 2. axle sleeve; 3. cambered blade; 4. reinforcement; 5. stiffener; 6. crimping.

Embodiment

Below in conjunction with drawings and Examples the utility model is done further non-limiting explanation:

Shown in Fig. 1 or 2, of the present utility model being characterised in that: it includes the axle sleeve 2 of band installed part 1, and wherein axle sleeve 2 is provided with a plurality of cambered blades 3.The utility model is work like this: in the time will carrying out farming to the deep water field, the utility model is installed on the paddyfield plough by installed part 1, driving axle sleeve 2 by engine rotates, cambered blade 3 also rotates farming earth thereupon simultaneously, curved knife 3 scrapes out little bulk with the earth piece, cambered blade 3 obviously increases with the contact area of earth, and the pressure of 3 pairs of earth of curved knife is reduced, thereby has prevented paddyfield plough sinking or sagging.

As shown in Figure 1, a plurality of cambered blades 3 are to be provided with like this: axially being provided with of axle sleeve 2 organized the cambered blades 3 that are dislocation arranged side by side more, and each is organized a plurality of cambered blades 3 in the cambered blade 3.

As shown in Figure 1, in order to reach better farming effect, organize cambered blade 3 is to be provided with so more: four groups of cambered blades 3 are arranged on the axle sleeve, and each is organized three cambered blades 3 in the cambered blade.

Shown in Fig. 1 or 2, in order to strengthen the intensity of curved knife, crimping 6 is arranged in the both sides of curved knife 3.

As shown in Figure 2,, improve the intensity of cambered blade 3 when work, be connected with reinforcement 4 between cambered blade 3 and the axle sleeve 2 in order to prevent cambered blade 3 distortion.

As shown in Figure 2, in order to strengthen the utility model globality intensity, each is organized and is connected with stiffener 5 between the cambered blade 3.Stiffener 5 can be curved, and stiffener also can form other shape as required.
