Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an elastic floating film pressing roller for a rice transplanting and film covering integrated machine and the rice transplanting and film covering integrated machine. Background Art

[0002] The rice transplanting and mulching machine is a vital tool in modern agriculture. Combining both transplanting and mulching functions, it delivers numerous benefits to crop cultivation through efficient and accurate operations. This machine simultaneously performs two key tasks: mulching and transplanting. The mulching roller plays a crucial role in the entire process. This roller ensures that the mulch adheres tightly to the soil, ensuring a smooth and even coverage of the field.

[0003] Most of the existing rice transplanting and mulching machines are equipped with film pressing rollers that have obvious defects. Generally speaking, these film pressing rollers do not have an adjustment function. They lack flexibility when dealing with fields with different soil types, different flatness, and different hardness. Since they are often directly and rigidly connected to the machine, problems will ensue once they enter uneven fields to work. When encountering raised or depressed areas or soils of different hardness, the film pressing roller cannot adjust parameters such as height and pressure in time according to the terrain. It is easy for the film to not be pressed in place, resulting in a loose fit between the film and the soil, affecting the soil's thermal insulation and moisture retention effect; or the film can be pressed too much, damaging the film and seedlings, which in turn has many adverse effects on the growth of crops. Utility Model Content

[0004] In view of the problems that the existing film pressing roller usually does not have an adjustment function and is directly and rigidly connected to the rice transplanting and covering machine, making it difficult to adapt to different fields, the utility model provides an elastic floating film pressing roller for the rice transplanting and covering machine and the rice transplanting and covering machine. The elastic floating film pressing roller can coarsely and finely adjust the initial position of the film pressing roller so that the film pressing roller is in a suitable position, and the film pressing roller is elastically connected to the rice transplanting and covering machine, so that the film pressing roller can adapt to the uneven terrain and inconsistent hardness of the field, thereby improving the film pressing effect of the film pressing roller.

[0005] The technical solution adopted by this utility model is:

[0006] An elastic floating film pressing roller for a rice transplanting and film covering machine includes an adjusting screw, a tension spring adjusting nut, a mounting seat, a tension spring, an adjusting mechanism and a film pressing roller. The mounting seat is fixed to the rice transplanting and film covering machine, the adjusting screw passes through the mounting seat and is movably connected to the mounting seat, the adjusting nut is threadedly connected to the adjusting screw and the adjusting nut is located above the mounting seat; the upper end of the tension spring is fixed to the adjusting screw, and the lower end of the tension spring is adjustably connected to the adjusting mechanism; the film pressing roller is installed on the adjusting mechanism.

[0007] Furthermore, the adjustment mechanism is an adjustment plate, and a plurality of adjustment holes are provided on the adjustment plate for detachable connection with the tension spring.

[0019] The present invention will be further described in detail below with reference to the specific embodiments of the drawings, but the protection scope of the present invention is not limited thereto.

[0020] Example 1

[0021] Figure 1This is a structural schematic diagram of the elastic floating film pressing roller for the rice transplanting and film covering machine described in the utility model. The elastic floating film pressing roller includes an adjusting screw 1, a tension spring adjusting nut 2, a mounting seat 3, a tension spring 4, an adjusting mechanism, and a film pressing roller 7. The mounting seat 3 is fixed to the rice transplanting and film covering machine. The adjusting screw 1 passes through the mounting seat 3 and is movably connected to the mounting seat 3. The adjusting nut 2 is threadedly connected to the adjusting screw 1 and is located above the mounting seat 3. It is used to limit the downward movement of the adjusting screw 1 on the mounting seat 3. The adjusting screw 1 generates a downward force by itself and the gravity of the parts below. The adjusting nut 2 limits the downward movement of the adjusting screw 1. By twisting the adjusting nut 2, the relative position relationship between the adjusting nut 2 and the adjusting screw 1 can be adjusted, and then the downward extension length of the adjusting screw 1 can be adjusted to achieve adjustment of the position of the parts below. The upper end of the tension spring 4 is fixed on the adjusting screw 1, and the lower end of the tension spring 4 is adjustably connected to the adjusting mechanism. In a specific embodiment, the adjusting mechanism is an adjusting plate 51, and a plurality of adjusting holes 6 are provided on the adjusting plate 51 for detachable connection with the tension spring 4. By disassembling the adjusting plate 51 and the tension spring 4 and reinstalling them to the adjusting holes 6 in appropriate positions, the position relationship between the adjusting plate 51 and the tension spring 4 can be adjusted, and the initial position of the film pressing roller 7 can be adjusted. In this embodiment, the number of adjusting holes 6 is 3. The tension spring 4 and the adjusting plate 51 can be connected by a pin, in which case the adjusting hole 6 is a pin hole; or the tension spring 4 and the adjusting plate 51 can be connected by a bolt, so that the relative position relationship between the tension spring 4 and the adjusting plate 51 can be adjusted by the pin or bolt, thereby adjusting the initial position of the film pressing roller 7 on the adjusting plate 51. The connection method between the tension spring 4 and the adjusting plate 51 can also be: Figure 2 As shown, the adjustment mechanism is an adjustment rod 52 with a sliding sleeve 9 externally sleeved thereon. Bolts are provided on the sliding sleeve 9 to limit the position of the sliding sleeve 9. That is, when the bolts are tightened, the bolts press against the adjustment rod 52, allowing the sliding sleeve 9 and the adjustment rod 52 to slide relative to each other. When the bolts are loosened, the sliding sleeve 9 and the adjustment rod 52 can slide relative to each other. The tension spring 4 is connected to the sliding sleeve 9, achieving a slidable connection between the tension spring 4 and the adjustment rod 52. When the relative position of the tension spring 4 and the adjustment rod 52 needs to be adjusted, the sliding sleeve 9 is slid after loosening the bolts so that the sliding sleeve 9 is in the appropriate position on the adjustment rod 52. The bolts are then tightened again to limit the sliding sleeve 9, thereby adjusting the relative position of the sliding sleeve 9 and the adjustment rod 52, that is, adjusting the relative position of the tension spring 4 and the adjustment rod 52, and thus adjusting the initial position of the laminating roller 7 on the adjustment rod 52.

[0022] The film pressing roller 7 is installed on the adjustment mechanism. In the specific embodiment, the film pressing roller 7 is rotatably connected to the adjustment mechanism through the rotating shaft 8, that is, the film pressing roller 7 is rotatably installed on the adjustment plate 51 or the adjustment rod 52. The rotatable film pressing roller 7 can reduce the friction between it and the film, reduce the wear of the film pressing roller 7 and the film, and avoid damage to the film; the rotating film pressing roller 7 can also disperse the wear and extend the service life of itself and the film.

[0023] In the present invention, the initial position of the laminating roller 7 can be adjusted by coarsely adjusting the initial position of the laminating roller 7 by engaging a pin or bolt through the adjustment hole 6, or by adjusting the sliding sleeve 9. The initial position of the laminating roller 7 can also be fine-tuned by turning the adjustment nut 2 to ensure that the laminating roller 7 is in a suitable position. During operation, the tension spring 4 provides elastic space for the laminating roller 7, allowing the laminating roller 7 to adapt to uneven field terrain and improve the laminating effect of the laminating roller 7.
