Deep tillage combined machine

Abstract

The present invention relates to an agricultural machine, specifically a deep tillage combined machine. The machine is composed of a frame, a deep tillage shovel mechanism and a soil crushing and suppressing mechanism. The deep tillage shovel mechanism of the present invention adopts two deep tillage shovels, which are arranged front to back and the shovel bodies are alternately offset outwards. After the operation, the soil under the seedlings is loosened, which is more conducive to the growth of crops. The soil crushing and suppressing mechanism adopts a slice with a notch and a movable pressure roller disc structure. The large soil blocks that appear during the operation are chopped by the slices on the soil crushing and suppressing mechanism, and the small soil blocks are crushed by the spikes on the pressure roller disc, while the surface soil is compacted. The movable pressure roller disc also serves the purpose of cleaning the soil sandwiched between and stuck on the slices at any time. The structure of the equipment is simple and reasonable. After the operation, the depth and width of the soil loosened by a single shovel reach more than 30 cm, so that the surface soil is flat, finely broken and compacted, and reaches a state ready for sowing.

Description

Technical Field

[0001] The present invention relates to agricultural machinery, in particular to a deep tillage and land preparation combined operation machine. Background Art

[0002] Currently, conservation tillage on my country's black soil is progressing from pilot demonstrations to standardized, large-scale promotion. The fundamental requirement of conservation tillage is to cover the ground with straw, minimize or eliminate all tillage activities, and instead use deep plowing to address soil compaction.

[0003] Most of the original deep plowing machines use a straight shovel deep plowing shovel structure, and the deep plowing area is between the rows of crops. The disadvantage is that it has no beneficial effect on the growth of crops, and the areas that need deep plowing are not loosened in place. In addition, the original deep plowing machines only focus on the depth of deep plowing, but do not pay attention to the width of the loose soil layer and the effect of topsoil treatment. The width of the loose soil layer and the topsoil treatment of the deep plowing belt do not meet the standards. When the surface is covered with straw, piles of straw are often dragged, and operations are even impossible. Summary of the Invention

[0004] The purpose of the present invention is to provide a deep loosening and land leveling combined operation machine. The equipment has a simple and reasonable structure. After the operation, the depth and width of the loose soil layer with a single shovel can reach more than 30 cm. In particular, it can make the surface soil flat, finely broken and compacted, and reach a state ready for sowing.

[0005] The object of the present invention is achieved in this way: a deep loosening and land leveling combined operation machine includes a frame, at least one deep loosening mechanism and at least one soil crushing and pressing mechanism.

[0006] Furthermore, the frame includes side beams on both sides, a suspension beam, a front deep sowing shovel fixed beam, a rear deep sowing shovel fixed beam and a rear beam arranged in sequence between the two side beams, an upper suspension frame and a lower suspension frame are provided on the suspension beam, and transverse adjustment holes are processed on the two side beams.

[0007] Furthermore, the deep plowing mechanism includes two deep plowing shovel fixing seats, a front deep plowing shovel and a rear deep plowing shovel. The front deep plowing shovel is set on the front deep plowing shovel fixing beam through the deep plowing shovel fixing seat, and the rear deep plowing shovel is set on the rear deep plowing shovel fixing beam through the deep plowing shovel fixing seat. The lower shovel tips of the front and rear installed deep plowing shovels are offset outward relative to the shovel arms, and the outward offset directions of the front and rear deep plowing shovels are opposite.

[0008] Furthermore, the soil crushing and pressing mechanism includes a soil crushing and pressing roller adjustment arm, a rotating shaft, a slice, a pressure roller disc and a core sleeve. The two soil crushing and pressing roller adjustment arms are arranged at the ends of the rotating shaft. The soil crushing and pressing roller adjustment arms are connected to the transverse adjustment holes on the side beam through the vertical adjustment holes thereon. The multiple slices and pressure roller discs are alternately mounted on the rotating shaft in sequence. A core sleeve is fixed between each pressure roller disc and the rotating shaft. There is a radial movable gap between the pressure roller disc and the core sleeve, and there is an axial gap between the pressure roller disc and each slice.

[0009] The present invention has the following advantages and positive effects due to the adoption of the above structure:

[0010] 1. The deep tillage machine of the present invention can ensure deep tillage to a depth of more than 30 cm and does not drag piles. At the same time, the loose soil layer with a single shovel reaches a width of 30 cm, and the surface of the ground is flat, finely broken and compacted, reaching a state ready for sowing. It meets the needs of conservation tillage of black soil in different regions and is an essential machine for the standardized implementation of conservation tillage.

[0011] 2. The deep tillage mechanism of the present invention adopts at least two deep tillage shovels, which are arranged front to back and alternately offset to the outside. After the operation, the soil under the seedlings is loosened, which is more conducive to the growth of crops.

[0012] 3. The soil crushing and suppressing mechanism of the present invention adopts a slice with a notch and a movable pressure roller disc structure. Large soil clods appearing during operation are chopped by the slices on the soil crushing and suppressing mechanism, and small soil clods are crushed by the spikes on the pressure roller disc. At the same time, the loose surface soil is compacted. The movable pressure roller disc also serves the purpose of cleaning the soil sandwiched between and stuck on the slices at any time.
