Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery technical field especially relates to a kind of soil turning equipment for agricultural planting. BACKGROUND

[0002] In the modernization agricultural production process, soil turning operation is the key basic link to ensure the good growth of crops, and its operation quality has far-reaching influence on the yield and quality of crops. Deep plowing as an efficient and sustainable agricultural cultivation method is increasingly widely used in agricultural production, which aims to reduce unnecessary soil turning, reduce energy consumption, and maintain the ecological structure of soil.

[0003] However, the existing soil turning equipment in the market has deficiencies when performing deep plowing operation. In actual soil turning process, especially in some soil environments with high viscosity or land that has not been deep plowed for a long time, a large number of clumped soil blocks of different sizes are often produced after soil turning. These clumped soil blocks not only hinder the circulation of air in the soil, reducing soil permeability, but also seriously interfere with the uniform infiltration and distribution of water in the soil, causing some soil to be too dry and unable to provide sufficient water for crops, affecting crop growth. SUMMARY

[0004] This section aims to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the utility model name to avoid obscuring the purpose of this section, the abstract of the specification and the utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the above problems of the soil turning equipment for agricultural planting, the utility model is proposed.

[0006] To solve the above technical problems, the utility model provides the following technical scheme: a soil turning equipment for agricultural planting, comprising a support, two rotating shafts are symmetrically arranged on the support, at least three mounting frames are equidistantly arranged on the rotating shafts, a plow is mounted on the mounting frame, and a rotating disc is rotatably connected to the mounting frame.

[0007] The outer edge of the rotating disc is provided with a bent portion, and when the rotating disc is rotated to any angle, the bent portion segment in the lower half area faces the inclined surface of the plow. A plurality of notches are uniformly formed on the rotating disc and the bent portion in the circumferential direction, and the inner contour of the plurality of notches and the outer contour of the bent portion jointly form a continuous cutting edge.

[0008] As a preferred scheme of the soil turning equipment for agricultural planting, the notch is in the shape of a "V", and the opening angle is 30-60°.

[0009] As a preferred embodiment of the agricultural tillage equipment described in this utility model, a plurality of breaking teeth are evenly arranged circumferentially on the side of the bending part away from the plow blade.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Reference Figures 1-3 This invention provides an agricultural soil-turning device, comprising a support 1, two symmetrically arranged rotating shafts 2 on the support 1, at least three mounting frames 3 equidistantly arranged on the rotating shafts 2, plow blades 4 mounted on the mounting frames 3, and a turntable 5 rotatably connected to the mounting frames 3. The turntable 5 is coaxial with the rotating shafts 2, and the bottom of the turntable 5 is higher than the bottom of the plow blades 4, ensuring that the soil clods turned out by the plow blades 4 can contact the turntable 5 when turning along its inclined surface, thereby compressing the clods of soil.

[0027] Land that hasn't undergone deep tillage for a long time will gradually become compacted, with an even higher density in the plow pan. When the plow blades (4) perform deep tillage, breaking up the compacted plow pan subjects the soil clods to significant pressure and shear forces. After the clods are turned over, due to their long-term compaction and tight bonding between soil particles, the newly formed clods exhibit strong mutual attraction, making them prone to clumping. Clumping not only hinders air circulation within the soil, reducing soil permeability and negatively impacting crop growth, but also...

[0028] The outer edge of the turntable 5 is provided with a bending section 51. When the turntable 5 rotates to any angle, the bending section 51 in the lower half faces the inclined surface of the plow blade 4. Several notches 52 are evenly opened along the circumference of the turntable 5 and the bending section 51. A single notch 52 is distributed on the turntable 5 and the bending section 51 and remains connected. The notch 52 is V-shaped with an opening angle of 30 to 60°. The inner contours of multiple notches 52 and the outer contours of the bending section 51 together form a continuous cutting edge 53. After the soil clods are turned over by the plow blade 4, they will move along the inclined surface of the plow blade 4 towards the turntable 5 until they come into contact with the bending section 51. Then, the cutting edge 53 will break the soil clods into fragments, thereby improving the soil turning effect.

[0029] Furthermore, during deep tillage operations, the turntable 5 experiences a force exerted by the soil clods upon contact, causing it to rotate. As the turntable 5 rotates, it drives the cutting edge 53 mounted on it to rotate as well. The rotating cutting edge 53, with its sharp cutting edge and the kinetic energy generated by its rotation, cuts and impacts the soil clods, enhancing the soil breaking effect and thoroughly breaking down and refining the originally compacted, large clods of soil.

[0030] A plurality of breaking teeth 54 are evenly arranged circumferentially on the side of the bending part 51 away from the plow blade 4. The outer ends of the breaking teeth 54 extend out of the notch 52 and the outer ends of the breaking teeth 54 are sharp. The sharp ends are at the same angle as the cutting edge 53 on the outer contour of the bending part 51 and are smoothly transitioned. The breaking teeth 54 can increase the collision area when the outside of the bending part 51 comes into contact with the soil clods, and the breaking teeth 54 have the ability to break after rotation, thereby improving the breaking effect on the soil clods.

[0031] like Figures 2-4 As shown, a connecting plate 6 is provided on the mounting frame 3, and a scraper 61 is provided at the bottom of the connecting plate 6. The scraper 61 is in the shape of a "T", and its bottom surface is parallel to the inner wall surface of the bending part 51. The gap between the bottom surface of the scraper 61 and the inner wall surface of the bending part 51 is 3-5mm. Both ends of the scraper 61 are provided with arc surfaces. The scraper 61 can quickly scrape off the soil clods attached to the surface of the bending part 51 after the turntable 5 rotates for one cycle, ensuring the smooth flow of the soil clod crushing area and preventing the accumulated soil clods from interfering with the subsequent crushing process of newly turned soil clods, thereby continuously ensuring the efficient crushing effect of soil clods.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
