Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to an anti-piling and ridging device suitable for clay soil. Background Technology

[0002] In mechanized agricultural operations, ridging devices are the core working components of land preparation machinery, and their performance directly affects the quality of ridging formation and subsequent agronomic effects such as sowing and irrigation. A reasonable ridging structure should have a stable trapezoidal cross-sectional shape, and the topsoil should have an appropriate density to support crop root development. However, existing ridging devices still have the following technical defects in practical applications: the retaining plates equipped with traditional devices generally have insufficient range of action, and the soil-retaining effect of the retaining plates is not ideal, causing soil to be splashed back into the formed furrows, resulting in soil accumulation in the furrows and requiring secondary furrow cleaning, increasing the workload; the ridging surface is relatively loose after ridging, and existing furrow cleaners lack the ability to compact the soil, resulting in a loose ridge surface with insufficient bonding between soil particles, making it prone to slope slippage and ridge collapse under the action of gravity and natural rainfall. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tillage device with adjustable plow frame height.

[0004] The technical solution of this utility model is:

[0005] A ridge-forming device for preventing soil accumulation in clay soils includes a frame, a connecting frame, a ditching disc, a ditch cleaner, and graded retaining components. The frame is characterized by having a connecting frame for connection to a traction device, a ditch cleaner at the rear end of the frame, and ditching discs symmetrically arranged on the frame. A main drive shaft for connection to the traction device is also provided on the frame, with baffles fixedly connected at an angle to the main drive shaft. Graded retaining components are symmetrically arranged on the frame, each comprising retaining plate I, retaining plate II, and retaining plate III. Retaining plate I is fixedly connected to the frame, and retaining plate II is fixedly connected to retaining plate II. Retaining plate II and retaining plate III are movably connected. A ridge-shaping plate is fixedly connected to the ditch cleaner.

[0011] Furthermore, the main drive shaft is connected to the transmission assembly 12 via a universal joint. The rotating assembly is mounted on the frame and has an output shaft connected to a bevel gear I. The grooved disc is connected to the drive shaft, and a bevel gear II is provided at the end of the drive shaft away from the grooved disc.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, a ridge-forming device for preventing soil accumulation in clay soil includes a frame 1, a connecting frame 2, a ditching disc 3, a ditch cleaner 4, and graded retaining components 5. The frame 1 is equipped with a connecting frame 2 connected to a traction device; the rear end of the frame 1 is equipped with a ditch cleaner 4; the ditching discs 3 are symmetrically arranged on the frame 1; a main drive shaft 6 connected to the traction device is provided on the frame 1, and a baffle 8 is obliquely fixedly connected to the main drive shaft 6; graded retaining components 5 are symmetrically arranged on the frame 1, each graded retaining component 5 including retaining plate I 5-1, retaining plate II 5-2, and retaining plate III 5-3; retaining plate I 5-1 is fixedly connected to the frame 1, retaining plate I 5-1 is fixedly connected to retaining plate II 5-2, retaining plate II 5-2 is movably connected to retaining plate III 5-3; and a ridge-shaping plate 7 is fixedly connected to the ditch cleaner 4.

[0027] The three-stage progressive retaining structure effectively constrains the trajectory of soil particles thrown by the trenching disc 3, significantly enhancing the interception capability of splashed soil and fundamentally solving the problem of soil falling back into the formed furrow due to insufficient retaining range in traditional devices. The movable connection design allows the retaining plates II5-2 and III5-3 to be adjusted as needed, further improving the adaptability to trenching of soils with different viscosity. While cleaning the residual soil in the trench, the trench cleaner 4 compacts and shapes the soil on the side of the ridge through the fixedly connected ridge shaping plate 7, solving the problem of loose ridge surface easily collapsing in traditional devices.

[0028] In a preferred embodiment of this utility model, the front end of retaining plate Ⅲ5-3 is hinged to retaining plate Ⅱ5-2; a cavity 5-21 corresponding to the size of retaining plate Ⅲ5-3 is opened inside retaining plate Ⅱ5-2, a groove 5-22 is opened in the cavity 5-21, a slide rail 5-31 corresponding to the groove 5-22 is fixed at the rear end of retaining plate Ⅲ5-3, and a positioning block 5-32 is fixed on retaining plate Ⅲ5-3; an elastic inlet plug 5-23 is provided around the opening of the cavity 5-21.

[0029] Specifically, the material of the inlet plug 5-23 is rubber.

[0030] The retaining plate Ⅲ5-3 is adjusted by the cooperation of the slide rail 5-31, the slide groove 5-22 and the hinge structure. The elastic inlet plug 5-23 forms a dynamic seal during the sliding process, preventing dust from entering the cavity 5-21. At the same time, its deformation characteristics can clean the dust stuck on the retaining plate Ⅲ5-3, preventing the components from getting stuck. The inlet plug 5-23 can also fix the retaining plate Ⅲ5-3. The cooperation and constraint between the slide groove 5-22 and the positioning block 5-32 ensure that the retaining plate Ⅲ5-3 will not move out of the cavity 5-21. The inlet plug 5-23 is made of rubber, which has a low production cost.

[0031] As a preferred embodiment of the present invention, the ditch cleaner 4 includes a main board (not shown in the figure, the rest are the same) and two side plates (not shown in the figure, the rest are the same), and the ridge shaping plate 7 is fixed on the side plates.

[0032] As a preferred embodiment of the present invention, small protrusions 15 are provided on the surfaces of the ditch clearer 4 and the ridge shaping plate 7; the addition of small protrusions 15 on the surface can reduce the amount of sticky soil adhering to the surface of the ditch clearer and the ridge shaping plate during the forward movement of the ridging device.

[0033] In a preferred embodiment of this utility model, trenching blades 11 are provided alternately on both sides of the trenching disc 3. The trenching blades 11 are divided into large trenching blades and small trenching blades. The trenching resistance is reduced by the coordinated operation of the large trenching blades and the small trenching blades.

[0034] like Figures 6 to 7As shown, the main drive shaft 6 is connected to the transmission assembly 12 via the universal joint 13. The transmission assembly 12 is mounted on the frame 1 and has an output shaft (not shown in the figure, but the rest are the same). The output shaft is connected to a bevel gear I 12-1. The grooved disc 3 is connected to the drive shaft 3-1. The end of the drive shaft 3-1 away from the grooved disc 3 is provided with a bevel gear II 3-2. The bevel gear I 12-1 of the output shaft of the transmission assembly 12 meshes with the bevel gear II 3-2 of the drive shaft 3-1.

[0035] The main drive shaft 6 is connected to the universal joint 13, which is connected to the drive gear shaft in the transmission assembly 12. Then, it cooperates with the meshing transmission of various bevel gears to realize the power transmission of the ridging device and unify the operating speed of the furrowing disc 3, thereby enhancing the operational stability of the equipment, significantly reducing the system failure rate, extending the maintenance cycle, and providing a reliable guarantee for efficient and stable tillage operations.

[0036] As a preferred embodiment of this utility model, an arc-shaped protective shell 10 is provided above the universal joint 13 and the transmission assembly 12. The arc-shaped protective shell 10 is fixedly connected to the retaining plate II 5-2. The arc-shaped protective shell 10 has an opening 10-1 above the universal joint 13. The arc-shaped protective shell 10 can prevent the dust raised from falling and accumulating above the universal joint 13 and the transmission assembly 12, causing the machine to overheat and affect its performance. The opening 10-1 on the arc-shaped protective shell 10 is to avoid affecting the connection and control between the main drive shaft 6 and the universal joint 13.

[0037] In a preferred embodiment of the present invention, a support rod 9 is movably connected to the frame 1, and the support rod 9 is fixed to the frame 1 by bolts 14. The support rod 9 can support the ridging device when it is not working, preventing the furrowing knife 11 and other parts from directly contacting the ground and being damaged. When the ridging device is working, the support rod 9 can be disassembled so as not to affect the operation of the ridging device.

[0038] The working process of this utility model is as follows: the ridging device is moved to the plot where ditching is required, and connected to traction equipment such as a tractor through the connecting frame 2 and the main drive shaft 6. Then the traction equipment starts to move forward, and the ridging device moves forward together. The power is transmitted to the transmission component 12 through the main drive shaft 6. Through the meshing and rotation of each bevel gear, the ditching disc 3 starts to drive and carry out the ditching work. During the forward movement, the ditch cleaner 4 cleans the soil in the ditch, and the ridge shaping plate 7 compacts and plasticizes the ridge surface. The graded soil retaining component 5 blocks the splashed soil. The soil retaining plate Ⅲ5-3 can be adjusted according to the soil splashing situation to prevent soil from splashing into the formed ridge. After the ditching work is completed, the support rod 9 of the ridging device is installed on the ridging device with bolts 14 to support the ridging device.

[0039] The above description is merely a preferred embodiment of this utility model. However, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, are all covered within the protection scope of this utility model.
