Description

Technical Field

[0001] This application relates to the field of plastic film recycling technology, specifically to a film removal machine for tobacco seedlings. Background Technology

[0002] Tobacco mulching technology is a widely used and practical agricultural technique in my country for increasing yields and income. This technology offers numerous advantages, including water conservation and drought resistance, soil warming and moisture retention, weed control, and cost reduction. However, if the mulch is not removed promptly during the seedling stage, it can hinder rainfall from entering the ridges. During periods of continuous rainfall, it can easily cause severe waterlogging, impairing soil permeability, hindering water evaporation, and ultimately affecting plant growth.

[0003] Therefore, recycling the plastic film during the tobacco seedling stage is beneficial to crop growth.

[0057] The end of the guide roller sleeve 32 away from the frame 1 is provided with a second retaining ring 35, the diameter of which is larger than the diameter of the guide roller sleeve 32.

[0058] Specifically, the first retaining ring 34 is used to prevent the guide roller sleeve 32 from falling off, and the second retaining ring 35 is used to prevent the mulch film from falling off.

[0059] In some embodiments, the active roller 42 and the passive roller 43 are fitted with a film clamping roller sleeve 41, and the outer side of the film clamping roller sleeve 41 is provided with a guide groove 47 surrounding the film clamping roller sleeve 41.

[0060] The film clamping system 4 also includes a scraper plate 46, which is located below the active roller 42 and the passive roller 43.

[0062] In some embodiments, the gear set 44 includes meshing gears respectively sleeved on the drive roller shaft 42 and the driven roller shaft 43. This enables the film clamping roller sleeve 41 to rotate in opposite directions, driving the mulch film downwards, and preventing the mulch film from sticking to the film clamping roller sleeve 41.

[0063] In some embodiments, the guide plate 51 is fence-shaped and has elongated holes extending along the width direction. The guide plate 51 has film-blocking edges 52 on its left and right sides. The guide plate 51 has a first upper pin hole 53 and a first lower pin hole 54 at its upper and lower ends, respectively. The first lower pin hole 54 of the upper guide plate 51 and the first upper pin hole 53 of the lower guide plate 51 are rotatably connected by a pin.

[0065] Specifically, the guide plate 51 is generally processed into a fence shape or a railing assembly to facilitate soil leakage. The membrane retaining edges 52 processed on both sides of the guide plate 51 are used to ensure that the mulch film falls into the collection box 6. The slider 59 drives the lower ends of the two guide plate 51 assemblies to move in a straight line, so that the mulch film is evenly spread in the collection box 6 by the movement of the guide plate 51 assemblies.

[0066] In some embodiments, a guide groove 13 is provided on the side of the frame 1 along the movement direction of the slider 59, and the pin connecting the first lower pin hole 54 of the lower end guide plate 51 and the guide plate pin hole 60 of the slider 59 passes through the guide groove 13.

The second upper pin hole 63 and the third upper pin hole 64, as well as the second lower pin hole 65 and the third lower pin hole 66, are fixedly connected by pins.

[0072] Specifically, the membrane collection box 61 is triangular in shape to facilitate membrane removal. During assembly, the second upper pin hole 63 and the third upper pin hole 64 are fixedly connected by a pin, allowing the membrane collection box cover 62 to rotate around the pin. During operation, the second lower pin hole 65 and the third lower pin hole 66 are connected by a pin. When membrane removal is required, the pin is pulled out, the box cover is opened, and the membrane is removed.

[0073] In some embodiments, a film-removing system 3, a film-clamping system 4, a film-guiding system 5, and a film-collecting box 6 are respectively provided on the left and right sides of the frame 1, which can simultaneously remove the plastic film on both sides of the frame 1. During film removal, the collection route of the plastic film is referenced... Figure 2 The gray line 'a' in the text.
