Description

Device for improving operation quality of rotary cultivator

Technical Field

The utility model relates to an improve device of rotary cultivator operating quality is the improvement that the rotary cultivator operating quality improves, belongs to the agricultural machinery and equips the field.

Background

When the existing rotary cultivator works, the rear cover plate is generally an integral plane panel which has the functions of preventing soil blocks from splashing and flattening or scraping the ridge surface. Due to the fact that the soil structure conditions are inconsistent under different operation conditions, when soil blocks are still large after rotary tillage or large soil blocks are encountered, the rotary cultivator has the problems that the load is increased or the leveling effect is poor, and the rotary cultivator jolts and jumps, so that the operation effect of the rotary cultivator is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the defects of the prior art and provides a device for improving the operation quality of a rotary cultivator. The utility model discloses a through the change to the back shroud structure on current rotary cultivator operation device basis, increase broken upturned soil and cutting tool's mode, improve rotary cultivator operation effect.

The technical scheme of the utility model as follows:

a device for improving the operation quality of a rotary cultivator comprises a rear cover plate of the rotary cultivator and is characterized in that a plurality of triangular sawtooth cutters are arranged on the inner side of the rear cover plate and used for upturned soil slicing; the triangular sawtooth cutters are uniformly welded on the rear cover plate, and sawteeth on the triangular sawtooth cutters are uniformly arranged along the inclined edges of the triangular sawtooth cutters.

Preferably, the triangular sawtooth cutters are welded on the rear cover plate at intervals in a staggered mode and are not in the same straight line, and mechanical operation resistance is reduced.

Preferably, the tooth point of the sawtooth and the bevel edge of the triangular sawtooth cutter form an included angle of 45 degrees, and the tooth point faces one side of the movable end of the rear cover plate.

Preferably, the length of the saw teeth is less than 1.5 cm.

Preferably, the triangular sawtooth cutter is a right triangle, the high side of the triangular sawtooth cutter is welded on the inner side of the rear cover plate, and the bevel edge provided with sawteeth faces the operation direction of the rotary cultivator.

Preferably, the base of the triangular sawtooth cutter is less than or equal to 3cm, and the height of the triangular sawtooth cutter is less than or equal to 4 cm.

Preferably, the triangular sawtooth cutter is stainless steel material, and the material is firm, improves the smooth finish, avoids being stained with mud and increases the operating resistance.

Preferably, the adjacent triangular sawtooth cutters are spaced 15-20cm apart.

The utility model discloses a through increase the method of cutting effect annex on the back shroud, effectively solve the rotary cultivator and jolt, the load increases and rectangular pieces of land in a field not good problem of surface quality. The utility model discloses have easy operation, cost increase few, work efficiency is high, overcome the not good workload that brings of rotary cultivator rotary tillage operation and increase, machinery jolts and the not good enough of effect, can reduce the workload, practice thrift rectangular pieces of land in a field face flattening expense.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a middle triangular sawtooth cutter of the present invention;

in the figure: 1. a triangular sawtooth cutter; 2. a movable end of a rear cover plate of the rotary cultivator; 3. saw teeth of the triangular saw-tooth cutter; 4. the bottom edge of the triangular sawtooth cutter; 5. height (welding surface) of the triangular sawtooth cutter; 6. the inner side of a rear cover plate of the rotary cultivator; 7. the rotary cultivator rear cover plate and the rotary cultivator connecting piece; 8. the rotary cultivator back shroud and rotary cultivator link.

Detailed Description

As shown in the figure, the upturned soil breaking device is arranged on the rear cover plate of the rotary cultivator, namely triangular saw-tooth cutters 1 are welded in a staggered mode on the inner side of one end, playing a scraping role, of the rear cover plate of the rotary cultivator, are spaced at intervals of 15-20cm and are not welded on a straight line, and are welded in a staggered mode, so that the working resistance of the rotary cultivator is reduced.

The triangular sawtooth cutter is preferably made of stainless steel, the size of the triangle is preferably 3cm at the bottom and 4cm at the height, and the high side is welded on the inner side 6 of the rear cover plate of the rotary cultivator.

The saw teeth 3 of the triangular saw tooth cutter are arranged on the inclined plane of the triangle, the tooth direction of the saw teeth faces to one side of the movable end 2 of the rear cover plate of the rotary cultivator, and the tooth length of the saw teeth is controlled within 1.5 cm.

The main points are as follows:

1. the triangular sawtooth cutter is not too large, so that the phenomenon that the operation load of the rotary cultivator is increased too much and sundries are wound to influence the operation effect of the rotary cultivator is avoided;

2. the saw teeth of the triangular saw-tooth cutter are not too long, and the main functions are to crush upturned soil and cut sundries; the overlong sawteeth can increase the operation resistance and wind sundries;

3. the triangular sawtooth cutter should select a material with good smoothness, so as to prevent soil from being adhered and influence operation;

4. the direction of the saw teeth is required to be correct, so that the upturned soil breaking and cutting are facilitated;

5. the welding of the sawtooth cutter needs to be firm, otherwise, the sawtooth cutter is easy to loosen or fall off, and the effect is influenced.

Adopt the utility model discloses, the machinery that appears under the great condition of clod soil when can effectively overcoming the rotary cultivator operation jolts, the load increases and the operation effect is poor not enough, can effectively carry out the breakage with big clod soil through the sawtooth cutter to reduce machinery operation's resistance, the rethread apron is strickleed off, improves rectangular pieces of land in a field face and levels the effect. Can improve the rotary tillage operation quality and reduce the operation load.
