Abstract
Description
Technical Field
[0001] The invention 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 film covering machine is an important tool in the development of modern agriculture. It integrates the functions of rice transplanting and film covering, and brings many benefits to crop planting with efficient and accurate operation. When this machine is in operation, it can simultaneously perform two key tasks, film covering and rice transplanting. The film pressing roller of the film covering part plays a vital role in the whole process. Through the film pressing roller, the ground film can be closely attached to the soil to ensure that the ground film is flat and evenly covered on the farmland soil.
[0003] Most of the existing film pressing rollers equipped with rice transplanting and film covering machines have obvious defects. Usually, these film pressing rollers do not have an adjustment function. They lack flexibility when facing fields with different soil types, different flatness, and different hardness. Since they are often directly and rigidly connected to the machine, once they enter the uneven field to work, problems will ensue. 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 heat preservation and moisture retention effect; or the film is pressed too much, damaging the film and seedlings, which in turn has many adverse effects on the growth of crops. Summary of the invention
[0004] In view of the problem that the existing film pressing roller usually has no adjustment function and is directly and rigidly connected to the rice transplanting and film covering machine, making it difficult to adapt to different fields, the present invention provides an elastic floating film pressing roller for the rice transplanting and film covering machine and the rice transplanting and film 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 film covering machine, so that the film pressing roller can adapt to the uneven terrain and soil with inconsistent hardness in the field, thereby improving the film pressing effect of the film pressing roller.

[0019] The present invention will be further described in detail below with reference to the specific implementation modes of the accompanying drawings, but the protection scope of the present invention is not limited thereto.
[0020] Embodiment 1
[0021] Figure 1This is a structural schematic diagram of the elastic floating film pressing roller for the rice transplanting and film covering integrated machine of the present invention, the elastic floating film pressing roller comprises 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 on the rice transplanting and film covering integrated 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 the adjusting nut 2 is located above the mounting seat 3, which 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, and 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 length of the adjusting screw 1 extending downward can be adjusted to achieve the 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 at 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 latch, 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 a latch or a 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 sleeve 9 on the outside, and a bolt is set on the sleeve 9 to limit the sleeve 9, that is, when the bolt is tightened, the bolt presses against the adjustment rod 52 so that the sleeve 9 and the adjustment rod 52 slide relative to each other, and when the bolt is loosened, the sleeve 9 and the adjustment rod 52 can slide relative to each other, and the tension spring 4 is connected to the sleeve 9 to achieve a slidable connection between the tension spring 4 and the adjustment rod 52. When the relative position relationship between the tension spring 4 and the adjustment rod 52 needs to be adjusted, the sleeve 9 is slid after the bolt is loosened so that the sleeve 9 is in a suitable position on the adjustment rod 52, and then the bolt is tightened to limit the sleeve 9, thereby adjusting the relative position of the sleeve 9 and the adjustment rod 52, that is, adjusting the relative position relationship between the tension spring 4 and the adjustment rod 52, and then adjusting the initial position of the film pressing roller 7 on the adjustment rod 52.
[0022] The film pressing roller 7 is installed on the adjusting mechanism. In the specific embodiment, the film pressing roller 7 is rotatably connected to the adjusting mechanism via a rotating shaft 8, that is, the film pressing roller 7 is rotatably installed on the adjusting plate 51 or the adjusting 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 film pressing roller 7 can be adjusted by adjusting the adjustment hole 6 in conjunction with the pin or bolt, or by adjusting the sliding sleeve 9, that is, the initial position of the film pressing roller 7 can be roughly adjusted; the initial position of the film pressing roller 7 can also be fine-tuned by screwing the adjustment nut 2, so that the film pressing roller 7 is in a suitable position. During the working process of the film pressing roller 7, the tension spring 4 can provide elastic space for the film pressing roller 7, so that the film pressing roller 7 can adapt to the uneven terrain in the field, and improve the film pressing effect of the film pressing roller 7.
