Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery, and in particular to the technical field of a deep tillage and ridging blade assembly and a deep tillage and ridging device. 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 mainly focuses on ditching, and the soil from the ditch needs to be removed manually or by other equipment or used for ridging. This results in low work efficiency. In addition, the soil discharge device is generally large. Smaller soil discharge devices may deviate from the preset trajectory when moving in the ditch, thus failing to effectively and orderly throw the soil onto the ridge and easily damaging crops.
[0004] Therefore, how to provide a device that is small in size, can break up the soil in the trench evenly, and will not deviate from the preset trajectory during the process, and throw the broken soil to both sides of the trench for backfilling, without damaging crops, has become an urgent problem to be solved in this field. Utility Model Content
[0005] To solve the above-mentioned technical problems, a deep tillage and hilling knife set and a deep tillage and hilling device are provided. The device is small in size and can break up the soil in the trench evenly. It will not deviate from the preset trajectory during the movement and will throw the broken soil to both sides of the trench for hilling without damaging the crops.
[0006] This utility model provides a deep tillage and hilling blade assembly, which includes a connecting shaft, and the connecting shaft is sequentially connected to a first blade disc, a second blade disc, a plurality of fourth blade sets, a second blade disc, and a first blade disc;
[0007] The diameter of the first cutter head is larger than the diameter of the second cutter head; the first cutter head and the second cutter head are arranged opposite to each other;
[0008] The first cutter head is connected to a first cutter group, a second cutter group, and a third cutter group;
[0009] The second cutterhead is connected to the first cutter group, the second cutter group, and the soil throwing device;
[0010] One side of the first cutter head is connected to the first cutter group, and the other side of the first cutter head is connected to the third cutter group; the first cutter head or a position near its edge is connected to the second cutter group.
[0011] The second cutterhead is connected to the first cutter group and the soil-throwing device on the side away from the first cutterhead, and the second cutter group is connected to the second cutterhead or near its edge; preferably, the second cutter group is connected to the side of the second cutterhead closer to the first cutterhead.
[0012] Compared with the prior art, the advantages of this utility model are as follows: the first cutter disc, the second cutter disc, several fourth cutter groups, the second cutter disc, and the first cutter disc are connected in sequence through the connecting shaft. The first cutter disc is connected to the first cutter group, the second cutter group, and the third cutter group. The first cutter disc is located on both sides of the connecting shaft. The first cutter disc helps to guide the deep tillage and hilling cutter group and prevents the deep tillage and hilling cutter group from deviating from the preset track during the movement. At the same time, it breaks up the soil that the first cutter disc passes through and throws the broken soil up.
[0013] The second blade assembly is connected to the edge of the first blade disc to break up the vegetation encountered by the first blade disc during its movement, thus avoiding the problem of plants getting tangled on the surface of the first blade disc. This further avoids the problem of the deep tillage and hilling blade assembly deviating from the preset track or slipping during its movement, which reduces the efficiency of breaking up the soil.
[0014] The second cutter head is connected to the first cutter group, the second cutter group, and the soil throwing device, which further improves the soil breaking efficiency and facilitates the throwing of the broken soil to both sides for backfilling.
[0015] By using a first cutter head with a diameter larger than the second cutter head, and by setting the first and second cutter heads opposite each other, the efficiency and uniformity of soil crushing are improved while reducing the resistance to movement.
[0016] The aforementioned sets of fourth blades ensure strong grip on the soil during deep tillage and hilling.
[0017] Furthermore, the first cutter head has a plurality of toothed structures circumferentially arranged on its edge; the second cutter head has a toothed structure circumferentially arranged on its edge.
[0018] and / or
[0019] The radial cross-section of the connecting shaft includes one of the following: triangular, quadrilateral, pentagonal, and hexagonal.
[0020] The first cutter head has a connecting hole at its center that is adapted to the connecting shaft, and the second cutter head has a connecting hole at its center that is adapted to the connecting shaft. The shape of the connecting hole includes one of the following: triangular, quadrilateral, pentagonal, and hexagonal.
[0021] The beneficial effect of the previous step is that by having several toothed structures circumferentially arranged on the edge of the first cutter head and the edge of the second cutter head circumferentially arranged with toothed structures, the grip of the deep tillage and ridging blade assembly is further improved, avoiding the phenomenon of the deep tillage and ridging blade assembly deviating from the preset trajectory during the movement, and without significantly increasing the resistance to movement.
[0022] The radial cross-section of the connecting shaft includes one of the following: triangular, quadrilateral, pentagonal, or hexagonal. This prevents slippage between the first and second cutter discs and the connecting shaft during the deep tillage and hilling blade assembly's operation.
[0023] Furthermore, the side of the first cutterhead closest to the second cutterhead is connected to a soil-throwing device;
[0024] Alternatively, both sides of the first cutterhead are connected to a soil-throwing device.
[0025] The beneficial effects of the previous step further facilitate the throwing of the broken soil to both sides, thereby further facilitating the backfilling process.
[0026] Furthermore, the first blade assembly includes three or four first blades;
[0027] The second blade assembly includes three or four second blades;
[0028] The third blade assembly includes three or four third blades;
[0029] The soil-throwing device includes three or four soil-throwing plates;
[0030] and / or
[0031] The fourth blade assembly includes a fifth blade connected to the connecting shaft and a sixth blade vertically connected to the fifth blade.
[0032] The beneficial effect of the previous step is that, by connecting the first cutter group, the first soil throwing device, and one surface 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.
[0033] The third cutter group and the second soil-throwing device are connected to another surface of the first cutter disc, 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.
[0034] This facilitates the uniform breaking up of the soil and its concentration on both sides of the ditch for backfilling.
[0035] The arrangement of several first blades and second blades around the circumference further facilitates the uniform breaking of the soil.
[0036] 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.
[0037] The second blade assembly includes several second blades. The second blade assembly is connected to the edge of the first blade disc. The second blades are set perpendicular to the first blade disc, which helps to break up the plants that the first blade disc passes through. This avoids plants and vines in the soil from getting tangled on the first blade disc, which would reduce the grip of the first blade disc and cause it to deviate from the preset trajectory during the process.
[0038] Furthermore, the three or four first blades are arranged circumferentially; the three or four third blades are arranged circumferentially.
[0039] The soil-throwing plate is spaced apart from the first blade; the soil-throwing plate is spaced apart from the second blade;
[0040] The second blade is perpendicular to the first cutter head; the second blade is perpendicular to the second cutter head;
[0041] and / or
[0042] The first blade is connected to a vertically arranged fourth blade; the third blade is connected to a vertically arranged fourth blade.
[0043] The beneficial effect of the previous step is that, by setting the soil-throwing plate and the first blade at intervals, and setting the soil-throwing plate and the second blade at intervals, it is also beneficial to improve the soil crushing efficiency and the degree of crushing uniformity.
[0044] By setting the second blade perpendicular to the first cutter disc and the second cutter disc perpendicular to the second cutter disc, the vegetation passing by the first and second cutter discs is crushed, avoiding the problem of vegetation getting entangled on the surface of the first and second cutter discs, which reduces the crushing efficiency. At the same time, it also avoids the problem of the deep tillage and hilling blade assembly deviating from the preset travel track.
[0045] The first blade is connected to a vertically arranged fourth blade, and the third blade is connected to a vertically arranged fourth blade, so that the vegetation can be broken up by the fourth blade, avoiding the problem of reduced breaking efficiency caused by the vegetation getting tangled on the surface of the first and third blades.
[0046] Furthermore, the first blade includes a first blade fixing part and a first blade cutting part (B).
[0047] The first blade fixing part is connected to the first cutter head, 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.
[0048] The first blade cutting section A has an arc-shaped structure;

[0051] The third blade fixing part is connected to the first cutter head, one end of the third blade cutting part A is connected to the third blade fixing part at an angle, and the other end of the third blade cutting part A is connected to the third blade cutting part B;
[0052] The third blade cutting section A has an arc-shaped structure.
[0053] 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.
[0054] Furthermore, the three or four first blade cutting sections A are arranged in a spiral shape;
[0055] The third blade cutting section A of the three or four third blades is arranged in a spiral shape.
[0056] The beneficial effect of the previous step is that by arranging multiple first blade cutting sections A in a spiral shape and multiple third blade cutting sections A in a spiral shape, it is beneficial to throw up the soil blocks during the crushing process, thereby facilitating multiple crushing of the soil blocks, improving crushing efficiency, and crushing the soil blocks evenly.
[0057] Furthermore, the soil-throwing plate is provided with an arc-shaped plate, the concave surface of which faces away from the edge of the first cutterhead; the concave surface of which faces away from the edge of the second cutterhead.
[0058] Three or four of the aforementioned arc-shaped plates are arranged in a spiral shape;
[0059] The spiral direction of the three or four said arc-shaped plates is opposite to the spiral direction of the three or four first blade cutting sections A;
[0060] The spiral direction of the three or four said arc plates is opposite to the spiral direction of the three or four third blade cutting sections A.
[0061] The beneficial effect of the previous step is that, since the spiral direction of the three or four arc-shaped plates is opposite to the spiral direction of the three or four first blade cutting parts A, it is beneficial to break the soil multiple times in the air, thereby further improving the uniformity and efficiency of soil clod breaking, which is conducive to backfilling the broken soil to the side of the ditch.
[0062] Furthermore, the first tool set is connected to one side of the first tool disc via a first connector;
