Technical Field

[0001] This technology belongs to the field of agricultural devices, especially a combined rotary tillage device. Background Art

[0002] The traditional rotary tillage device is just a rotary tillage roller, with a single function and unable to lift. Summary of the Invention

[0003] To solve the above problems, the present invention proposes a combined rotary tillage device.

[0004] This combined rotary tillage device is installed on the upper crossbeam of the rear axle of an agricultural crawler. It is characterized in that first vertical hydraulic cylinders are fixed on both sides of the upper crossbeam. A channel steel is horizontally welded on the left side of the upper crossbeam. The first vertical hydraulic cylinders are connected to a lower crossbeam through inverted L-shaped rods. Plows are connected to the front and rear sides of the lower crossbeam. Horizontal support rods are installed on the front and rear sides of the lower crossbeam. A first rotating shaft is installed between the horizontal support rods on the right side of the lower crossbeam. Several first discs are installed on the first rotating shaft. Several rotary tillage blades are evenly distributed along the center of the first discs. There is a protective cover on the right side of the first rotating shaft. The two sides of the top of the protective cover are hinged to the lower crossbeam through first arc-shaped rods. A cage is installed between the horizontal support rods on the right side of the protective cover. The rear end of the cage is connected to the rear end of the first rotating shaft through a first sprocket set. The cage and the first rotating shaft move in opposite directions. There is an iron wall between the horizontal support rods on the right side of the cage. Second vertical hydraulic cylinders are fixed on the horizontal support rods on both sides of the iron wall. The second vertical hydraulic cylinders are connected to the iron wall. An arc-shaped cover is welded on the top of the iron wall. The front and rear sides of the arc-shaped cover are hinged to the lower crossbeam through second arc-shaped rods. Conical teeth are evenly distributed under the iron wall. A winnowing roller is installed between the horizontal support rods on the right side of the arc-shaped cover. The winnowing roller includes a second rotating shaft. Pairs of second discs are evenly distributed on the second rotating shaft. Several transverse iron sheets are evenly distributed on the circumference between each pair of second discs. There is an arc-shaped iron plate between the horizontal support rods on the right side of the winnowing roller. Support seats are located on the horizontal support rods on both sides of the arc-shaped iron plate. A third hydraulic cylinder is obliquely fixed on the horizontal support rods. The left end of the arc-shaped iron plate is hinged to the lower part of the support seat. The right end of the arc-shaped iron plate is connected to the third hydraulic cylinder.

[0005] Furthermore, the vertical part of the inverted L-shaped rod passes through the channel steel, and a limit block is fixedly connected to the inverted L-shaped rod above the channel steel.

[0006] Furthermore, there are two left and right blades on the plow. The length of the right blade is greater than that of the left blade. A rotary grass cutting blade is installed on the left blade. The rotary grass cutting blade is connected to the front part of the first rotating shaft through a second sprocket set. When sowing rapeseed, the right blade is installed, and the right blade is removed at other times.

[0007] Preferably, there is a vertical rotating shaft on the front side of the first rotating shaft. The first rotating shaft is connected to the vertical rotating shaft through a bevel gear pair.

[0008] Preferably, arc-shaped teeth are evenly distributed at the lower part of the protective cover, with the arc tops of the arc-shaped teeth facing the direction of the rotary tillage blades, and the arc-shaped teeth break up the mud brought by the rotary tillage blades.

[0009] Preferably, several circular blades are evenly distributed at the center of the auger, and the rotation directions of the feeding blades on both sides of the circular blades cause the materials coming from both sides to gather towards the middle.

[0010] Preferably, the rotation direction of the feeding blades of the auger causes the materials in the middle to spread out towards both sides.

[0011] The beneficial effects of the present invention are as follows: First, the lifting of the entire rear combined rotary tillage device can be achieved through the first hydraulic cylinder; second, when deep ditches need to be plowed during the conversion of fields, the plow can be equipped with longer right-side blades for tillage; at this time, the auger twists from both sides to the center. When converting fields into farmland, the right-side blades that can be removed from the plow are used for tillage. When plowing the first pass of the farmland, the auger twists from the center to both sides, and the auger is removed when plowing the second pass. BRIEF DESCRIPTION OF THE DRAWINGS

The screw conveyor 12 and the first rotating shaft 7 move in opposite directions. There is an iron wall 14 between the horizontal support rods 6 on the right side of the screw conveyor 12. Second vertical hydraulic cylinders 15 are fixed on the horizontal support rods 6 on both sides of the iron wall 14. The second vertical hydraulic cylinders 15 are connected to the iron wall 14. An arc-shaped cover 16 is welded on the top of the iron wall 14. The front and rear sides of the arc-shaped cover 16 are hinged to the lower crossbeam 4 through second arc-shaped rods 24. Conical teeth 14.1 are evenly distributed below the iron wall 14. A winnowing roller 17 is installed between the horizontal support rods 6 on the right side of the arc-shaped cover 16. The winnowing roller 17 includes a second rotating shaft 17.1. Pairs of second discs 17.2 are evenly distributed on the second rotating shaft 17.1. Several cross iron sheets 17.3 are evenly distributed on the circumference between each pair of second discs 17.2. There is an arc-shaped iron plate 18 between the horizontal support rods 6 on the right side of the winnowing roller 17. Support seats 19 are located on the horizontal support rods 6 on both sides of the arc-shaped iron plate 18. A third hydraulic cylinder 20 is obliquely fixed on the horizontal support rods 6. The left end of the arc-shaped iron plate 18 is hinged to the lower part of the support seat 19.
