Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a film-laying and soil-covering device. Background Technology

[0002] Agricultural machinery refers to all kinds of mechanical equipment used in agricultural production, including large and small tractors, land leveling machinery, etc. In planting operations, these machines are often used to lay mulch and cover the soil to improve the soil environment and promote crop growth.

[0003] In existing membrane laying and soil covering operations, especially during the soil covering process, the unstable shape of the soil storage space inside the excavator bucket often leads to the soil scattering and uneven distribution during the throwing process, which in turn affects the efficiency and accuracy of the operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a membrane laying and soil covering device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A membrane laying and soil covering device, comprising:

[0007] The baffle has guide grooves on its inner curved surface along the curvature direction;

[0008] A pair of buckets are rotatably mounted at the bottom of a baffle, with a gap between the rotating end of the bucket and the inner curved surface of the baffle;

[0009] An arc-shaped elastic plate, the sliding end of which slides along the length of the guide groove, the inner curved surface of the elastic plate always dynamically fits the opening side of the bucket rotating in the gap to form a soil storage space.

[0010] As the bucket pushes the elastic plate along the rotation trajectory to slide to the end in the guide groove, the bucket continues to rotate, forcing the inner surface of the elastic plate to deform in the opposite direction, changing the curvature from positive to negative, instantly opening the soil storage space and directionally throwing the soil to the original excavation position of the bucket.

[0011] Preferably, the soil storage space formed by the inner wall of the bucket opening and the inner curved surface of the elastic plate is a dynamic wedge-shaped cavity, and its radial cross section is a triangular shape with a closed base.

[0012] Preferably, the extended end of the elastic plate is arranged parallel to the inner wall of the bucket opening side.

[0013] Preferably, the arc-shaped elastic plate is made of carbon fiber reinforced shape memory polymer composite laminate, and the curvature of the inner surface of the elastic plate changes from negative to positive after the bucket is detached from the bucket.

[0014] Preferably, a reset member is provided in the initial end of the guide groove. The two ends of the reset member are respectively connected to the inner wall of the baffle and the sliding end of the elastic plate. After the bucket is disengaged from the elastic plate, it is pulled back to the initial end.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention utilizes the combination of a bucket and an elastic plate to ensure effective storage and directional throwing of soil within the storage space. By gradually compressing the soil and reducing the volume of the storage space, it ensures the compactness and stability of the soil during storage, thereby preventing soil scattering during release and making soil release more precise and efficient.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model. Example

[0023] like Figure 1-Figure 3 As shown, a membrane laying and soil covering device includes:

[0024] The baffle 1 has a guide groove 11 formed on its inner curved surface along the curvature direction;

[0025] A pair of buckets 2 are rotatably mounted at the bottom of the baffle 1, and a gap is left between the rotating end of the buckets 2 and the inner curved surface of the baffle 1;

[0026] The arc-shaped elastic plate 3 slides along the length of the guide groove 11 at its sliding end. The inner curved surface of the elastic plate 3 is always dynamically in contact with the opening side of the bucket 2 rotating in the gap to form a soil storage space.

[0027] As the bucket 2 pushes the elastic plate 3 along the rotation trajectory to slide to the end in the guide groove 11, the bucket 2 continues to rotate, forcing the inner curved surface of the elastic plate 3 to deform in the opposite direction, changing the curvature from positive to negative, and instantly opening the soil storage space to directionally throw the soil to the original excavation position of the bucket 2.

[0028] When bucket 2 is driven to rotate by an external power source, and a pair of buckets 2 alternately dig and dump soil, after digging, when bucket 2 rotates into the gap, the inner curved surface of elastic plate 3 dynamically fits against the opening side of bucket 2 to form a soil storage space. As bucket 2 pushes elastic plate 3 to slide along its rotation trajectory, the inner curved surface of elastic plate 3 remains dynamically fitted against the opening side of bucket 2. As bucket 2 continues to rotate, elastic plate 3 slides to the end of guide groove 11. At this time, the rotational speed and direction of bucket 2 push elastic plate 3 to slide, forcing the inner curved surface of elastic plate 3 to deform in the opposite direction. The instant the curvature changes from positive to negative, the soil storage space is opened, the stored soil is rapidly released, and the soil is directionally thrown back to the original digging position of bucket 2.

[0029] The soil storage space formed by the inner wall of the opening side of bucket 2 and the inner curved surface of elastic plate 3 is a dynamic wedge-shaped cavity, with a radial cross-section that is a near-triangular shape with a closed base. The extended end of elastic plate 3 is set parallel to the inner wall of the opening side of bucket 2. As bucket 2 rotates and elastic plate 3 slides, the shape of the dynamic wedge-shaped cavity changes. The rotation of bucket 2 not only pushes elastic plate 3 to slide within guide groove 11, but also gradually changes the shape and size of the soil storage space. Due to the contact between elastic plate 3 and the inner wall of the opening side of bucket 2, the soil storage space gradually becomes narrower, forming a wedge-shaped area. As the rotation occurs, the volume of the wedge-shaped cavity decreases, the soil is further compressed within the cavity, the soil density increases, and the interaction force between soil particles strengthens, thus preventing the soil from scattering during release. When the soil storage space suddenly opens, the stored soil will not immediately scatter over a large area, but will be directionally thrown along a specific path to the original digging position of bucket 2.

[0030] The elastic plate 3 is made of carbon fiber reinforced shape memory polymer composite laminate. After the bucket 2 is detached, the curvature of the inner surface of the elastic plate 3 changes from negative to positive. When the bucket 2 is detached, the elastic plate 3 is no longer subjected to continuous external force, and the effect of the shape memory polymer comes into play. Due to the shape memory effect of its inner surface, the elastic plate 3 will return to its original predetermined shape, and the curvature of the inner surface will gradually change from negative to positive.

[0031] A reset member 4 is provided in the initial end of the guide groove 11. The two ends of the reset member 4 are respectively connected to the inner wall of the baffle 1 and the sliding end of the elastic plate 3. After the bucket 2 is disengaged from the elastic plate 3, it is pulled back to the initial end. The reset member 4 includes a wire roller 41 disposed in the guide groove 11 through an elastic rotating shaft. A torsion spring is sleeved on the rotating shaft. The free end of the wire wound on the surface of the wire roller 41 is connected to the sliding end of the elastic plate 3. The wire is limited and stretched in the guide groove 11, not exceeding the range of the guide groove 11. After the elastic plate 3 is disengaged from the bucket 2, it is pulled back to the initial position.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
