DETAILED DESCRIPTION

[0019] Embodiment 1

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a transmission mechanism of a ground film recovery machine is applied to a film collecting roller 7 and a film separating roller 8, and includes a bevel gear box 1 and a universal coupling 2. The bevel gear box 1 includes a power input end 11 and a power output end 12. The power output end 12 is respectively connected with a first transmission component 3 for driving the film separating roller 8 to rotate, and a second transmission component 4 for driving the film collecting roller 7 to rotate. The power input end 11 is connected to one end of the universal coupling 2, and the other end of the universal coupling 2 is connected to the power source 5 of the ground film recovery machine 9.

[0021] The power is transmitted to the film separating roller 8 and the film collecting roller 7 respectively through the first transmission assembly 3 and the second transmission assembly 4 on the power output end 12 of the bevel gear box 1. Since the first transmission assembly 3 and the second transmission assembly 4 are installed at the power output end 12 of the bevel gear box 1 at the same time, the entire transmission mechanism driving the film separating roller 8 and the film collecting roller 7 is located on the same side, which reduces the installation space of the entire transmission mechanism on the ground film recovery machine, avoids the problem of overcrowding caused by insufficient transmission space, and ensures the uniform distribution of power of the first transmission assembly 3 and the second transmission assembly 4, improves the transmission efficiency, improves the agricultural production efficiency and machine life, and reduces the agricultural production cost. At the same time, it can also prevent the mold collecting roller from slipping in more extreme cases, and avoid damage to the transmission mechanism when it is subjected to excessive impact. Secondly, the transmission connection between the power source 5 of the ground film recovery machine and the power input end 11 of the bevel gear box 1 is realized through the universal coupling 2. With the help of the power source 5 of the ground film recovery machine, there is no need to install other power sources 5, which simplifies the overall structure. In addition, the universal coupling 2 can realize long-distance transmission and change of direction of power, which improves the quality of power transmission.

[0022] The other end of the universal coupling 2 is connected to the power source 5 of the ground film recovery machine through a third transmission assembly 6. The third transmission assembly 6 includes a driving pulley 61, a driven pulley and a transmission belt 63 arranged on the driving pulley 61 and the driven pulley. The driven pulley is arranged on the other end of the universal coupling 2, and the driving pulley 61 is arranged on the power source 5 of the ground film recovery machine. The third transmission assembly 6 is used to achieve smooth transmission of power between the power source 5 and the universal coupling 2. The third transmission assembly 6 is arranged to include a driving pulley 61, a driven pulley and a transmission belt 63, which is easy to install and disassemble and has a good transmission effect.

[0023] The first transmission component 3 includes a first sprocket 31, a second sprocket 32 ​​and a first transmission chain 33. The first sprocket 31 is arranged on the power output end 12, and the second sprocket 32 ​​is installed on the film separating roller 8. The first transmission chain 33 is arranged on the first sprocket 31 and the second sprocket. The second transmission component 4 includes a third sprocket 41, a fourth sprocket 42 and a second transmission chain 43. The third sprocket 41 is arranged on the power output end 12, and the fourth sprocket 42 is arranged on the film collecting roller 7. The second transmission chain 43 is arranged on the third sprocket 41 and the fourth sprocket 42. The first transmission component 3 and the second transmission component 4 are both arranged into a sprocket transmission structure to ensure the stability of the transmission. In addition, the rotation speed of the mold collecting roller and the film separating roller can be controlled by setting the transmission ratio between the first transmission component and the second transmission component to achieve the optimal efficiency of ground film recovery. When the traveling speed of the ground film recovery machine is 7-12km, the rotation speed of the mold collecting roller is 40r / min, and the transmission ratio i is 14, the ground film recovery efficiency is optimal.

[0024] The power output end 12 includes an output shaft 13, and the first sprocket 31 and the third sprocket 41 are both arranged on the output shaft 13, and a spacer sleeve 14 is provided on the output shaft 13, and the spacer sleeve 14 is arranged between the first sprocket 31 and the third sprocket 41. The output cycle can realize the quick installation of the first sprocket 31 and the third sprocket 41, and the first sprocket 31 and the third sprocket 41 are separated by the spacer sleeve 14, thereby reducing the relative independence of the first sprocket 31 and the third sprocket 41 during rotation, thereby improving the transmission efficiency. A fixed retaining spring 15 is also provided on the output shaft 13, which can prevent the axial movement of the first sprocket 31 and the third sprocket 41, thereby improving the rotation efficiency of the first sprocket 31 and the third sprocket 41. The diameter of the first sprocket 31 is larger than the diameter of the third sprocket 41, which can not only control the film separating roller 8 and the film collecting roller 7 to be under different rotation speeds, but also can be distinguished by the diameter of the sprocket during installation, thereby improving the installation efficiency. When in use, sprockets of different diameters can be set according to actual working needs to meet different needs.

[0025] Embodiment 2

[0026] like Figure 1 As shown, the present embodiment further discloses a ground film recovery machine, comprising a film collecting roller 7, a film separating roller 8 and a transmission mechanism arranged between the film collecting roller 7 and the film separating roller 8, wherein the transmission mechanism is the transmission mechanism described in the first embodiment. Since the entire transmission mechanism can be located on the same side of the ground film recovery machine, the transmission mechanism for driving the blade roller mechanism and the auger roller on the ground film recovery machine can be installed on the other side, thereby evenly distributing the transmission power on each side and improving the overall transmission efficiency.

[0027] In addition to the above preferred embodiments, the present invention has other implementation modes. Those skilled in the art may make various changes and modifications based on the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined by the claims attached to the present invention.
