Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to an adjustable double-plow ridging device and a four-wheel riding micro-tillage machine. Background Art

[0002] A four-wheeled riding micro-tillage machine is a small tillage machine mainly used for agricultural operations, comprising two front wheels and two rear wheels. Both the front wheels or the rear wheels can be removed and replaced with tillage tools. The operator sits on the four-wheeled riding micro-tillage machine to cultivate the fields. When planting different crops, ridges of different widths need to be formed. However, the current ridging device can only form ridges of fixed width. There is an urgent need for a ridging device that can be suitable for the four-wheeled riding micro-tillage machine and can form ridges of different widths according to the needs of planting crops. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide an adjustable double-plow ridging device that can raise ridges of different widths according to the needs of growing crops.

[0004] The technical solution adopted by the present invention is as follows: an adjustable double-plow ridging device, applied to a four-wheel ride-on micro-tillage machine, including a plowing assembly for plowing the land and a leveling assembly for leveling the soil that are symmetrically arranged and can be relatively adjusted in position. The two groups of the plowing assembly and the leveling assembly are used together for ridging farmland.

[0005] Principle of the technical solution:

[0006] Since the positions of the plowing components can be adjusted relative to each other, when ridges of different widths need to be formed, the positions of the plowing components are adjusted so that the two sets of plowing components move toward or away from each other, and then the soil leveling components are used to form corresponding ridges for crops.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The two groups of plowing components of the utility model can adjust their positions relative to each other, that is, they can move toward each other or move away from each other, so that the two groups of plowing components are close to or far away from each other. When the two groups of plowing components are close to each other, with the addition of the soil leveling component, ridges with a small width can be formed. When the two groups of plowing components are far away from each other, with the addition of the soil leveling component, ridges with a large width can be formed.

[0009] As a preferred embodiment of the present invention, it also includes a connecting frame connected to the four-wheel ride-on micro-tiller, the plowing assembly includes an adjusting member and a plowing member connected to the adjusting member, the leveling assembly includes a first connecting member and a leveling member connected to the first connecting member, the first connecting member is located between the two adjusting members, and the two adjusting members and the first connecting member are respectively detachably connected to the connecting frame.

[0010] Beneficial effects: the two adjusting parts and the connecting frame are detachably connected, and the position of the plowing part can be adjusted, thereby adjusting the width of the ridge, and can be used for ridge formation for different crops.

[0011] As a preferred embodiment of the present utility model, the adjusting member includes a first connecting column, two second connecting members, and a limit plate. The first connecting column is connected to the plowing member, the first connecting column and the limit plate are respectively located on both sides of the connecting frame, the two second connecting members are respectively fitted with the upper surface of the connecting frame and the lower surface of the connecting frame, one end of the two second connecting members are respectively fixedly connected to the first connecting column, and the other end are respectively detachably connected to the limit plate.

[0012] In this solution, the two second connecting parts are held and driven to slide on the connecting frame. The second connecting parts drive the plowing part to move through the first connecting column, and then the limiting plate is connected to the second connecting part to limit the second connecting part, and the first connecting column is limited by the second connecting part, that is, the plowing part is limited.

[0013] Beneficial effects: The two second connecting members and the limiting plate are detachably connected, which can indirectly ensure the stable connection between the plowing member and the connecting frame, and can also adjust the position of the plowing member.

[0014] As a preferred embodiment of the present invention, the plowing piece includes an arc-shaped plate, a first support column, and a second support column. The inner surface of the arc-shaped plate is an outwardly convex curved surface. The arc-shaped plate is tilted. The distance between the two arc-shaped plates close to the leveling piece is smaller than the distance between the two arc-shaped plates away from the leveling piece. One end of the first support column is connected to the arc-shaped plate, and the other end is connected to the second support column. The second support column is tilted and connected to the arc-shaped plate. The connection between the second support column and the first support column is away from the connection between the first support column and the arc-shaped plate.

[0015] In this solution, the inner surface of the arc plate is an outwardly convex curved surface, the arc plate is inclined, and the distance between the two arc plates on the side close to the leveling piece is smaller than the distance between the two arc plates on the side away from the leveling piece. The two arc plates on the side away from the leveling piece can plow out more soil, and when the two arc plates pass the side close to the leveling piece, the soil is gathered together to complete the ridge formation.

[0016] As a preferred embodiment of the present invention, a deep plowing plate and a first connecting plate are provided at the lower end of the curved plate. The first connecting plate is connected to the outer surface of the curved plate and extends out of the lower end of the curved plate. The first connecting plate and the deep plowing plate are detachably connected. The first connecting plate is respectively fitted with the outer surface of the curved plate and the outer surface of the deep plowing plate, and the outer edges of the first connecting plate are away from the outer edges of the deep plowing plate.

[0017] Beneficial effects: Since the lower end of the arc-shaped plate needs to extend into the ground when forming ridges, it will come into contact with gravel and sand. Long-term contact with gravel and sand will wear off the lower end of the arc-shaped plate, affecting subsequent use. The deep plowing plate and the first connecting plate are detachably connected. When the deep plowing plate is severely worn, the deep plowing plate can be replaced to ensure effective ridge forming.

[0018] As a preferred embodiment of the present invention, the first connecting member includes a second connecting column, a first connecting tube, and a third connecting column. One end of the second connecting column is connected to the connecting frame, and the other end is connected to the first connecting tube. The third connecting column extends into the first connecting tube and is detachably connected to the first connecting tube. The lower end of the third connecting column extends out of the first connecting tube and is connected to the leveling piece.

[0019] Beneficial effect: The third connecting column and the first connecting tube are detachably connected, which makes it easy to clean the leveling piece.

[0020] As a preferred embodiment of the present invention, a plurality of first connecting holes are provided at axial intervals along the second connecting column at one end where the second connecting column is connected to the connecting frame, and a second connecting hole that can overlap with the first connecting hole is provided on the connecting frame, and the first connecting column is detachably connected to the connecting frame through the first connecting hole and the second connecting hole.

[0021] In this solution, when the soil-leveling piece needs to be moved close to the connecting frame, the second connecting column moves axially along the second connecting column, so that the first connecting hole close to the soil-leveling piece coincides with the second connecting hole.

[0022] Beneficial effect: The position between the soil-leveling piece and the connecting frame can be adjusted by cooperating with the multiple first connecting holes and the second connecting holes.

[0023] As a preferred embodiment of the present invention, the soil leveling member includes a second connecting plate and a scraping plate, one end of the second connecting plate is connected to the first connecting member, and the other end is connected to the scraping plate, and the surface of the scraping plate is an inwardly concave curved surface.

[0024] As a preferred embodiment of the present utility model, the connecting frame includes a fourth connecting column connected to the four-wheel riding micro-tiller, a fifth connecting column perpendicular to and connected to the fourth connecting column, and a second connecting tube connected to the fifth connecting column, the first connecting member extends into the second connecting tube and is detachably connected to the second connecting tube, and the adjusting member is connected to the fifth connecting column.

[0025] Beneficial effect: The first connecting member and the second connecting tube are detachably connected, which makes it easy to clean and replace parts.

[0042] like Figure 3 As shown, the soil leveling assembly includes a first connecting member 3 and a soil leveling member 4 connected to the first connecting member 3. The first connecting member 3 is located between the two adjusting members 1.
