Description

Technical Field

[0001] The utility model relates to the technical field of land preparation devices, and in particular to a combined land preparation device. Background Art

[0002] A soil preparation device is a piece of mechanical equipment used to prepare the soil for planting by loosening, breaking up and leveling the soil to improve its structure and quality.

[0003] The existing land preparation device works by breaking and mixing the soil with a rotating cutter and then leveling the soil surface with a leveling device.

[0004] Although this can loosen and level the soil, the following problems still exist: since the rotary cutter has insufficient crushing force on the deep soil, it can only loosen the surface soil and cannot break the plow bottom layer, making it difficult for the soil to drain through the plow bottom layer. Utility Model Content

[0005] The utility model provides a combined soil preparation device, which solves the problem of soil drainage difficulty after the soil preparation device works in the prior art and improves the practicability of the device.

[0006] The technical solution of the utility model is as follows:

[0007] A combined land preparation device includes a fixing frame,

[0008] The fixing frame is provided with a plurality of first deep loosening structures for deep loosening the plow bottom layer of the soil, a plurality of first soil turning structures for turning and loosening the soil in a direction away from the fixing frame, a plurality of second deep loosening structures for secondary deep loosening of the plow bottom layer of the soil, and a plurality of second soil turning structures for turning and loosening the soil in a direction away from the other side of the fixing frame. The fixing frame is also provided with a mounting structure for mounting the fixing frame on a tractor.

[0009] Furthermore, the first deep loosening structure includes a deep loosening member, which is an arc-shaped structure. A mounting groove is provided at one end of the deep loosening member, and the mounting groove is a square structure. The slot of the mounting groove is threadedly connected with a limiting bolt. A first shovel member and a second shovel member are respectively fixed on both sides of the other end of the deep loosening member. The first shovel member and the second shovel member are both obtuse-angled triangular structures. The second deep loosening structure is the same as the first deep loosening structure.

[0010] Furthermore, the first soil-turning structure includes a soil-turning piece, a first mounting piece is fixed on the fixed frame, a connecting piece is rotatably connected to the first mounting piece, the soil-turning piece is rotatably connected to the connecting piece, and a limit spring is also provided between the first mounting piece and the connecting piece, and the two ends of the limit spring are respectively fixedly connected to the first mounting piece and the connecting piece.

[0011] Further, the soil-turning member is of a disc-shaped structure, and a plurality of crushing gaps are provided on the outer periphery of the soil-turning member. The outer ends of each of the crushing gaps away from the outer periphery of the soil-turning member are of a semi-circular structure, and the ends of each of the crushing gaps close to the outer periphery of the soil-turning member are of a rectangular structure.

[0012] Further, a second mounting member and a third mounting member are slidably connected to the first mounting member. The second mounting member and the third mounting member are both of a "冂"-shaped structure. Locking bolts are threadedly connected to the ends of the second mounting member and the third mounting member, and the locking bolts abut against the first mounting member. The structures of the first soil-turning structure and the second soil-turning structure are the same.

[0013] Further, the soil-turning members of the first soil-turning structure and the second soil-turning structure are symmetrical to each other. The fixing frame includes a first mounting beam and a second mounting beam. The first mounting beam and the second mounting beam are parallel. A third mounting beam, a fourth mounting beam, a fifth mounting beam and a sixth mounting beam are fixed between the first mounting beam and the second mounting beam. The third mounting beam, the fourth mounting beam, the fifth mounting beam and the sixth mounting beam are parallel to each other. The first subsoiling structure is fixedly connected to the first mounting beam, the first soil-turning structure is fixedly connected to the second mounting beam, the second subsoiling structure is fixedly connected to the third mounting beam, and the second soil-turning structure is fixedly connected to the fourth mounting beam.

[0014] Further, the mounting structure includes a fourth mounting member. The fourth mounting member includes a first support plate, a second support plate and a mounting portion. The first support plate and the second support plate are both of a right-angled trapezoidal structure. The first support plate and the second support plate are parallel to each other.

[0016] The working process of this embodiment: First, the fourth mounting member is installed and fixed to the tractor through the mounting holes on the fourth mounting member, and then the fixing frame is moved by the movement of the tractor. At this time, the soil to be prepared is embedded by the subsoiling members on the first deep tillage structure, and the plough sole of the soil is damaged. The subsoiled soil is turned and loosened to the side away from the fixing frame by the soil-turning members of the first soil-turning structure. This soil is then deeply tilled again by the subsoiling members of the second deep tillage structure and is turned and loosened to the other side away from the fixing frame by the soil-turning members of the second soil-turning structure.

[0017] This embodiment sequentially arranges a first subsoil loosening structure, a first soil turning structure, a second subsoil loosening structure, and a second soil turning structure on a fixed frame. This allows the soil to undergo a first subsoil loosening, which drives the soil to the side away from the fixed frame for loosening, followed by a second subsoil loosening, which drives the soil to the other side away from the fixed frame for loosening. This replaces the prior art design that directly uses rotating cutters to break up and mix the soil. The present invention breaks up and loosens the plow bottom layer, improving the drainage capacity of the soil plow bottom layer and providing greater practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 2 to 5 As shown, this embodiment proposes a combined land preparation device, the structure of which includes a fixed frame 1. In this embodiment, a plurality of first deep loosening structures 2, a plurality of first soil turning structures 3, a plurality of second deep loosening structures 4, and a plurality of second soil turning structures 5 are sequentially arranged on the fixed frame 1. Among them, the first deep loosening structure 2 is used to deep loosen the plow bottom layer of the soil. The first soil turning structure 3 is used to turn and loosen the soil in a direction away from the fixed frame 1. The second deep loosening structure 4 is used to perform a secondary deep loosening on the plow bottom layer of the soil. The second soil turning structure 5 is used to turn and loosen the soil in a direction away from the other side of the fixed frame 1. The mounting structure is provided on the fixed frame 1, and is used to mount the fixed frame 1 on a tractor.

[0028] The first soil-turning structure 3 in this embodiment includes a soil-turning member 33, a first mounting member 31 fixedly mounted on the fixing frame 1, a connecting member 32 rotatably mounted on the first mounting member 31, and the soil-turning member 33 is rotatably connected to the connecting member 32. This design allows the soil-turning member 33 to rotate against the soil when the tractor drives the land preparation device to move, thereby turning the soil. A limit spring 34 is disposed between the first mounting member 31 and the connecting member 32, with the two ends of the limit spring 34 fixedly connected to the first mounting member 31 and the connecting member 32, respectively. The design of the limit spring 34 allows the soil-turning member 33 to turn the soil closely against the soil, thereby improving the soil-turning efficiency. The rotation direction of the soil-turning member 33 used in this embodiment is at an acute angle to the movement direction of the fixing frame 1, ensuring that the soil can flow into the soil-turning member 33 and turn over during the movement of the fixing frame 1.

[0029] The soil turning member 33 in this embodiment is a disc-shaped structure, and a plurality of crushing notches 331 are arranged on the periphery of the soil turning member 33. The outer peripheral end of each crushing notch 331 away from the soil turning member 33 is a semicircular structure, which is used to increase the amount of soil entering the crushing notch 331. The outer peripheral end of each crushing notch 331 close to the soil turning member 33 is a rectangular structure, which not only increases the amount of soil entering the crushing notch 331, but also the smooth arc surface can effectively reduce soil resistance. Such a crushing notch 331 design not only allows the notch to cut into the soil, pry and cut large pieces of soil, and break it into smaller particles, but also increases its contact area with the soil, improves the crushing effect, makes the crushed soil more uniform, and helps to improve the structure of the soil to adapt to subsequent tillage or sowing.

[0030] In this embodiment, the second mounting member 35 and the third mounting member 36 are slidably arranged on the first mounting member 31. Both the second mounting member 35 and the third mounting member 36 are of a "冂" - shaped structure. The locking bolt 351 is arranged at the ends of the second mounting member 35 and the third mounting member 36 through threaded connection. The locking bolt 351 abuts against the first mounting member 31. The structure of the first soil - turning structure 3 is the same as that of the second soil - turning structure 5. Such a design enables quick installation or disassembly of the first mounting member 31 on the fixed frame 1 by simply rotating the locking bolt 351, which is convenient for repairing and replacing the soil - turning member 33 when it is damaged.

[0031] The mounting structure in this embodiment includes a fourth mounting member 6. The fourth mounting member 6 includes a first support plate 61, a second support plate 62 and a mounting portion 63. Both the first support plate 61 and the second support plate 62 are of a right - angled trapezoid structure. The first support plate 61 and the second support plate 62 are parallel to each other. The mounting portion 63 is of a "7" - shaped structure. A number of mounting holes 631 are arranged on the mounting portion 63. The design of multiple mounting holes 631 enables the fourth mounting member 6 to adapt to different tractors, facilitating traction by various types of tractors and improving its scope of application. The two ends of the first support plate 61 are fixedly connected to the mounting portion 63 and the fixed frame 1 respectively. The two ends of the second support plate 62 are fixedly connected to the mounting portion 63 and the fixed frame 1 respectively. The first support plate 61 and the second support plate 62 adopted in this embodiment make the fourth mounting member 6 more stable and reliable. [[ID=​​​The first deep loosening structure 2 in this embodiment includes a deep loosening member 21, which is an arc-shaped structure. The mounting groove 22 is provided at one end of the deep loosening member 21. The mounting groove 22 is a square structure. The limit bolt 221 is threadedly connected to the notch of the mounting groove 22 to facilitate the installation and fixation of the deep loosening member 21 and the fixing frame 1. The first shovel member 211 and the second shovel member 212 are fixedly provided at the other end of the deep loosening member 21. The first shovel member 211 and the second shovel member 212 are both obtuse-angled triangular structures to expand the deep loosening range of the deep loosening member 21 so that more soil can be deep loosened. The second deep loosening structure 4 has the same structure as the first deep loosening structure 2. Such a design of the deep loosening member 21 enables the deep loosening member 21 to be embedded in the plow bottom layer deep in the soil and destroy the plow bottom layer, so that more gaps are generated between the soil in the plow bottom layer, which is convenient for drainage and water storage.

[0034] The working process of this embodiment is as follows: first, the fourth mounting member 6 is mounted and fixed to the tractor through the mounting hole 631 on the fourth mounting member 6. Then, the movement of the tractor drives the fixed frame 1 to move. At this time, the soil to be tilled is embedded by the deep tillage members of the first deep tillage structure, the plow bottom layer of the soil is destroyed, and the deep loosened soil is driven by the tillage members 33 of the first tillage structure 3 and pried to the side away from the fixed frame 1 for flipping and loosening. The soil is then deep-tilled again by the deep tillage members of the second deep tillage structure and, driven by the tillage members 33 of the second tillage structure 5, is flipped and loosened to the other side away from the fixed frame 1.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
