[0001] The utility model relates to the technical field of double-layer film covering of cotton, in particular to a thickened and degradable double-film sowing device. Background Art

[0002] In recent years, during the cotton planting process, the complex and changeable climate in late March and early April has caused the cotton to be affected by frost, rain, strong winds and other low-temperature weather during the seedling stage, reducing the number of seedlings and causing a reduction in cotton production. In order to increase the yield of seed cotton, farmers will choose to use sowing devices with environmentally friendly degradable films and thickened films that are easy to recycle to carry out double-film sowing operations, laying the foundation for the later maturity of cotton and increased production and income.

[0003] When the thickened and degradable double-film sowing device in the prior art uses a double-film method to achieve cotton seed sowing operations, it is generally covered with a degradable film layer first, then precision sowing is performed, and finally covered with a thickened film. However, considering some special cases, the film layer may have wrinkled edges when covering the ground film. The wrinkled film layer may easily have uneven and uneven covering in subsequent covering operations, which will directly affect the work quality of the device using a double film to efficiently plant cotton. Therefore, a thickened and degradable double-film sowing device is proposed to address the above problems. Utility Model Content

[0020] like Figure 1As shown, the lower film roll 3 and the upper film roll 5 are sleeved on the clamping roller bracket provided at the bottom of the frame body 1, and the film layers provided on the outside of the lower film roll 3 and the upper film roll 5 are respectively pressed and connected with a group of auxiliary pressure rollers 8. By respectively setting the lower film roll 3 and the upper film roll 5, the two can respectively lay the degradable film layer and the thickened film layer on the surface of the planting ground when the device is started, so that the cotton seeds can grow normally; the soil covering turntable 4 and the traction bracket provided at the bottom of the frame body 1 are rotatably connected, and the top of the frame body 1 is provided with a connecting frame 18 and a hopper 17 from left to right in sequence, and the connecting machine The frame 18 has a "V"-shaped structure. The "V"-shaped connecting frame 18 mainly serves to quickly connect the auxiliary device to the driving body. The discharge end of the hopper 17 passes through the interior of the frame body 1 and is connected to the feed end of the sowing turntable body 6. The outside of the sowing turntable body 6 is connected to the sowing discharge hopper 19. The sowing discharge hopper 19 is distributed in a circular array structure along the center point of the sowing turntable body 6. Under the mutual conduction setting, the cotton seeds in the hopper 17 can be accurately delivered to the interior of the sowing turntable body 6 for subsequent sowing operations.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a front and rear group of suction fans 15 are respectively fixedly installed on the vertical bracket 7, the outer shape of the limiting bracket 9 is set in an "H"-shaped structure, the air outlet of the exhaust hood 10 is set opposite to the edge of the film layer, the exhaust hood 10 is set in an inclined structure, the upper guide roller 11 and the lower guide roller 12 are respectively rotatably set at the upper and lower positions of the limiting bracket 9 through the short rotating shaft 16, the upper guide roller 11 and the lower guide roller 12 are respectively connected to the film layer winding to form a staggered structure, because the upper guide roller 11 and the lower guide roller 12 are respectively connected to the film layer winding, when the film layers are released from the film roll and unfolded, the setting of the upper guide roller 11 and the lower guide roller 12 will play a role in guiding the auxiliary film layer to achieve flat spreading.

[0022] Working process: When the device in the utility model starts running, the electric energy required comes from the power module on the driving vehicle body, and before using the entire sowing device, the device and the traction end of the driving vehicle body can be connected together through the connecting frame 18. When the thickened degradable double-film sowing device is needed, the farmer can first lay the film layers on the upper film roll 5 and the lower film roll 3 in an up-and-down stacking manner to the head end of the planting field. After the entire device is towed by the driving vehicle body, it is regularly driven in the cotton planting field through the walking roller 2. The degradable film layer on the lower film roll 3 will be neatly laid on the surface of the planting field after being released. At the same time, under the action of traction, the entire device will generate a throwing force when the sowing turntable body 6 rotates synchronously with the vehicle, and the sowing hopper 19 is used to dig a planting hole in the lower degradable film layer, so that the cotton seeds inside the sowing turntable body 6 can be accurately planted into the soil. Then, after a proper amount of soil is pushed onto the lower degradable film layer by the soil covering turntable 4, the device will cover the upper thickened film layer onto the lower degradable film layer by releasing and rotating the upper film roll 5, so that a double film structure is formed between the two film layers, which is conducive to the normal growth of cotton seeds. The above double film sowing technology is a disclosed prior art, and when the degradable film layer and the thickened film layer are released and unfolded from the lower film roll 3 and the upper film roll 5 respectively, under the limiting action of the limiting bracket 9 and, the device will use the upper guide roller 11 and the lower guide roller 12 to guide and assist the film layer released and unfolded to achieve the laying operation. At the same time, the suction fan 15 after starting will accurately suck both sides of the edge of the film layer through the suction pipe 14, the suction joint 13 and the exhaust hood 10, so that the device can suck and smooth the film layer with wrinkles on the edge, so as to avoid the problem of wrinkled edges causing uneven and uneven film layers after laying.
