Furrow plough main plough body with soil breaking sheet
Technical Field
The utility model relates to the technical field of agricultural machinery design and manufacture, in particular to a main plow body of a furrow plow with a soil breaking sheet.
Background
The main plough body of the furrow plough is a farming implement for turning upturned soil, breaking soil blocks and ploughing grooves to prepare for sowing, and mainly comprises a plough share, a plough wall, a plough side plate, a plough support, a plough column and the like, wherein the plough wall and the plough share form a plough body curved surface. The curved surface of the plough body is a streamline curved surface, and the effects of smooth upturned soil turning, thorough soil turning and light and quick ploughing are achieved. In practical application, the field soil slides over the smooth curved surface and falls on one side of the streamline curved surface. However, when the soil with high viscosity is encountered, the turned soil blocks are dry-accumulated into blocks and are not easy to break under the insolation of sunlight, which brings great difficulty to subsequent soil breaking and field leveling, and not only takes labor but also has mistaking farming season; if not thoroughly addressed, it will also result in uniformity of planting and direct impact on crop yield.
Disclosure of Invention
In order to solve the problem that the sticky clod-plowing field soil can be accumulated into blocks and is not easy to be broken, the utility model provides a main plow body of a furrow plow, which is provided with a soil breaking piece.
The utility model discloses a following technical scheme implements: the utility model provides a share plough main plough body with piece breaks ground, includes the moldboard and the piece breaks ground, the moldboard on be equipped with streamline curved surface, its characterized in that:
and a soil breaking piece is arranged in the middle of the streamline curved surface on the plough wall, and the bottom edge of the soil breaking piece is fixedly connected with the streamline curved surface.
Furthermore, the ground breaking piece is erected on the streamline curved surface.
Furthermore, the one side of each ground breaking piece is arranged along the sliding track direction of the soil on the streamline curved surface.
Furthermore, the upper end of the soil breaking opening of the soil breaking piece is inclined backwards relative to the lower end, and the inclination angle is larger than or equal to 60 degrees.
The utility model discloses, set up the piece that breaks ground on the diapire curved surface of main plough body, when the field soil is by the diapire upturned soil and the gliding of flow line shape curved surface, its glide plane is crossed by the piece that breaks ground and flows down a broken soil groove. When the soil of upturned soil is exposed to the sun under the sunlight and is deformed, the soil breaking groove can generate breaking stress concentration, so that the large soil blocks formed by dry accumulation are cracked and broken in the depth direction along the soil breaking groove, and convenience is brought to subsequent soil crushing and field leveling.
The utility model has the advantages of reasonable design, simple structure, good ground breaking effect and strong practicability.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the attached fig. 1: 1 is a plough wall and 2 is a soil breaking sheet.
Detailed Description
The invention will be further explained with reference to the following drawings:
as shown in attached figure 1, a streamline curved surface is arranged on the plough wall 1, a ground breaking piece 2 is arranged in the middle of the streamline curved surface, and the bottom edge of the ground breaking piece 2 is fixedly connected with the streamline curved surface on the plough wall 1; the ground breaking pieces 2 are erected on the streamline curved surface; the surface of the soil breaking piece 2 is arranged along the track direction of the soil sliding on the streamline curved surface; the upper end of the soil breaking opening of the soil breaking piece is inclined backwards relative to the lower end, and the inclination angle is equal to 60 degrees.
When the utility model works, the soil is ploughed by the plough wall 1 and slides along the linear curved surface of the edge, and the sliding surface of the soil is scratched by the soil breaking piece 2 to flow the next soil breaking groove. When the upturned soil is exposed under sunlight to deform, the breaking groove can generate breaking stress concentration, so that large blocks of dry and agglomerated soil can be cracked and broken in the depth direction along the breaking groove, and convenience is brought to subsequent soil crushing and field leveling.
