Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more particularly to the technical field of deep tillage and ridging blades and deep tillage and ridging devices. Background Technology

[0002] With the development of modern agriculture, the planting of various crops is now achieved through mechanization, which has improved production efficiency;

[0003] Agricultural production requires both ditching and ridging. Traditional agricultural machinery is mainly used for ditching, and the soil from the ditch needs to be removed manually or by other equipment or used for ridging; resulting in low work efficiency.

[0004] Therefore, how to provide a device that can break up the soil in a trench evenly and throw the broken soil to both sides of the trench for backfilling has become a problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a deep tillage and hilling knife and a deep tillage and hilling device are provided, which can break up the soil in the trench evenly and throw the broken soil to both sides of the trench for hilling.

[0006] This invention provides a deep tillage and hilling blade, characterized in that it includes a first blade disc, a first blade group, a second blade group, a third blade group, a first soil-throwing device, and a second soil-throwing device;

[0007] The first cutter group and the first soil-throwing device are connected to one side of the first cutter head;

[0008] The third cutter group and the second soil-throwing device are connected to the other side of the first cutter head;

[0009] The first blade assembly includes a plurality of first blades, which are arranged circumferentially;

[0010] The first soil-throwing device includes a plurality of first soil-throwing plates; the first soil-throwing plates are spaced apart from the first blades;

[0011] The third blade assembly includes a plurality of third blades, which are arranged circumferentially.

[0012] The second soil-throwing device includes a plurality of second soil-throwing plates; the second soil-throwing plates are spaced apart from the third blade;

[0013] The second blade assembly includes several second blades. The second blade assembly is connected to or near the edge of the first blade disc, and the second blades are arranged perpendicularly to the first blade disc.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by connecting the first cutter group, the first soil throwing device and one side of the first cutter disc, the soil in the trench is broken by the first cutter group; and the broken soil is thrown to both sides by the first soil throwing device.

[0015] The third cutter group and the second soil-throwing device are connected to the other side of the first cutter head, so that the soil near the inside of the trench is broken up by the third cutter group and the broken soil is thrown up by the second soil-throwing device.

[0016] This facilitates the uniform breaking up of the soil and its concentration on both sides of the ditch for backfilling.

[0017] The arrangement of several first blades and second blades around the circumference further facilitates the uniform breaking of the soil.

[0018] The first soil throwing device includes a plurality of first soil throwing plates; the first soil throwing plates and the first blades are spaced apart to enable the soil to be broken up multiple times during the throwing and falling process, thereby improving the breaking efficiency and enabling the soil to be thrown up and concentrated to both sides in a timely manner.

[0019] The second blade assembly includes several second blades. The second blade assembly is connected to or near the edge of the first cutter disc. The second blades are set perpendicular to the first cutter disc, which helps to break up the plants that the first cutter disc passes through. This avoids plants and vines in the soil from getting tangled on the first cutter disc, which would reduce the grip of the first cutter disc and cause it to deviate from the preset trajectory during the process.

[0020] Furthermore, the first cutter head is a disc; and / or,

[0021] The first cutter head has a connecting hole at its center, and the shape of the connecting hole includes one of the following: triangular, quadrilateral, pentagonal, and hexagonal.

[0022] The advantages of the previous step are that the first cutter head is a disc, which helps to reduce the travel resistance; and the shape of the connecting hole includes one of the following: triangular, quadrilateral, pentagonal, and hexagonal, which facilitates the connection between the connecting shaft and the first cutter head and avoids the phenomenon of shaft slippage during travel.

[0023] Furthermore, the disk has several tooth-like structures circumferentially arranged around its edge.

[0024] The beneficial effect of adopting the previous step is that it further improves the grip of the deep tillage and ridging device, avoids deviation from the preset trajectory during the movement, and does not significantly increase the resistance to movement.

[0025] Furthermore, the first blade includes a first blade fixing part and a first blade cutting part (B).

[0032] The beneficial effect of the previous step is that one end of the first blade cutting part A is connected to the first blade fixing part at an angle, and the other end of the first blade cutting part A is connected to the first blade cutting part B. The first blade cutting part A has an arc-shaped structure, which further facilitates the uniform crushing of the soil.

[0033] Furthermore, the first blade is connected to a vertically arranged fourth blade; the third blade is connected to a vertically arranged fourth blade;

[0034] and / or

[0035] The first blade assembly includes three first blades; or, the first blade assembly includes four first blades.

[0036] and / or

[0037] The third blade assembly includes three third blades; or, the third blade assembly includes four third blades.

[0038] Furthermore, the first blade is connected to a vertically arranged fourth blade; the third blade is connected to a vertically arranged fourth blade; the first blade assembly is connected to one side of the first blade disc through a first connector, so as to break up the grass or vegetation encountered during the soil breaking process, and avoid the vegetation or grass from getting tangled on the first blade assembly, which would prevent soil breaking or reduce soil breaking efficiency.

[0039] The first connector includes three or four first receiving cavities; the first blade fixing part is partially or entirely disposed in the first receiving cavity, and the first blade is fixed by the fixing part, and the first receiving cavity is connected to the first cutter head;

[0040] and / or

[0041] The third blade assembly is connected to the other side of the first blade disc via a second connector;

[0042] The second connector includes three or four second receiving cavities; the third blade fixing part is partially or entirely disposed in the second receiving cavity, and the third blade is fixed by the fixing part, and the second receiving cavity is connected to the first cutter head.

[0044] Furthermore, the first blade cutting portion A of the plurality of first blades is arranged in a spiral shape; the third blade cutting portion A of the plurality of third blades is arranged in a spiral shape.

[0045] The beneficial effect of the previous step is that, by setting the first blade cutting part A in a spiral shape, it is beneficial to throw up the soil clods during the crushing process, thereby facilitating multiple crushing of the soil clods, improving crushing efficiency, and crushing the soil clods evenly.

[0046] Furthermore, the first soil-throwing plate is provided with a first arc-shaped plate, the concave surface of the first arc-shaped plate facing away from the edge of the first cutterhead;

[0057] Compared with the prior art, the beneficial effects of the present invention are as follows: by using a deep tillage and hilling blade, the soil in the trench is broken up, and the soil clods are broken up with high efficiency and uniformity. At the same time, the broken soil is thrown to the side of the trench for hilling.

[0058] It also helps to improve the grip of the deep tillage and hilling device, avoiding the problem of the deep tillage and hilling device deviating from the preset track.

[0059] Furthermore, the deep tillage and hilling device also includes a plurality of rotary tillage and hilling blades connected to the connecting shaft; the plurality of rotary tillage and hilling blades are arranged between two deep tillage and hilling blades;
