Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural film recycling technology, and in particular to an agricultural film recycling device. Background Technology
[0002] Agricultural mulch film has significant advantages in preventing pests and diseases and retaining moisture, thus it has a wide application prospect in crop cultivation. While its advantages are obvious, its drawbacks are also prominent. For example, the inconvenience of mulch film recycling is a major drawback. After one or more crop cycles, the mulch film needs to be recycled for soil regeneration, weed control, and crop root and stem treatment. Currently, most methods involve directly using a plow to regenerate the soil and then collecting the film. However, this method often leaves film residue in the soil and has low recycling efficiency. If the film is not broken up before recycling, the difficulty of recycling increases with the distance the film has traveled, and the recycled film is not easily reusable. Utility Model Content
[0003] This utility model provides an agricultural film recycling device to overcome the shortcomings of the prior art and solve the problem of inconvenient recycling of agricultural film, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:
[0005] A plastic film recycling device includes a horizontal plate with movable plates installed at both ends. A square tube is bolted to the outer end of the movable plate, and a sleeve is bolted to both ends of the square tube. A lower extension arm is provided on the sleeve, and a roller is rotatably provided at the lower end of the lower extension arm. By setting the roller, the recycling device can be moved along the path where the plastic film is laid as needed, so as to facilitate the recycling of plastic film.
[0006] Lower extension plates are bolted to both ends of the horizontal plate. Bearing seats are installed on the inner side of the lower end of the lower extension plates. A winding rod is rotatably mounted between the bearing seats. End shafts are provided at both ends of the winding rod. The winding rod facilitates the winding of the mulch film, which provides convenience for subsequent mulch film recycling.
[0007] One of the square tubes is fitted with a side plate, and one end shaft passes through the side plate. The upper end of the side plate is equipped with a rotating shaft, and the outer end of the rotating shaft is connected to a drive wheel via a key. One of the end shafts is equipped with a driven wheel, and the driven wheel and the drive wheel are driven by a belt. Through the provided transmission system, the winding rod can be rotated, thereby facilitating the winding purpose.
[0008] Furthermore, in order to expand the range of application to accommodate the recycling of plastic film of different widths, a pair of screws are threaded to both ends of the horizontal plate, and a pair of slotted holes are opened on the movable plate. The screws are inserted into the slotted holes, and the lower end of the screw cap acts on the upper wall of the movable plate.
[0009] Furthermore, in order to facilitate the rotation of the drive wheel, a handle is provided eccentrically on the drive wheel.
[0010] Furthermore, in order to ensure that the transmission system can still drive the winding rod to rotate when the position of the movable plate is adjusted, an inner spline sleeve is rotatably provided at the lower end of the side plate. A limit ring is connected to the inner spline sleeve by a pin. The limit ring is located on the inner and outer sides of the side plate. The outer end of the inner spline sleeve is installed on the driven wheel by a screw. The inner spline sleeve is sleeved on the end shaft located on the same side. The outer end of the end shaft is provided with a spline shaft, and the inner spline sleeve is sleeved on the spline shaft.
[0011] Furthermore, in order to facilitate the scraping off of residual soil on the mulch film, a pair of diagonal bracing arms are bolted to the lower extension plate. The outer ends of the diagonal bracing arms extend downward at an angle, and scrapers are welded to the outer ends of the diagonal bracing arms. The lower end of the scrapers has a blade-shaped structure.
[0012] Furthermore, to prevent soil from falling onto the mulch film, the upper wall of the scraper is formed with a baffle.
[0013] Furthermore, in order to fix the end of the mulch film to facilitate the winding operation, a V-shaped groove is provided on the winding rod, and a retaining strip is embedded in the V-shaped groove. The outer wall of the retaining strip has an arc-shaped structure, and a pair of retaining grooves are provided at both ends of the retaining strip. Multiple capped pins are provided at both ends of the winding rod, and a protruding plate is fitted on the capped pin. A retaining ring is provided at the outer end of the protruding plate. The retaining ring has a notch, and the two ends of the notch of the retaining ring are respectively engaged in the retaining groove.
[0014] Furthermore, in order to improve the fixing effect of the clips on the mulch film, multiple teeth are provided on the inner wall of the clips.
[0015] Furthermore, to facilitate the transfer of the recycling device, an upper extension rod is welded to the sleeve at one end. A sleeve is welded to the upper end of the upper extension rod, and a gripping rod is inserted inside the sleeve. A locking screw is threaded onto the sleeve, and the lower end of the locking screw is pressed against the gripping rod.
[0016] The advantages of the above technical solution are:
[0017] This invention facilitates the recycling of plastic film and reduces the difficulty of recycling. Attached Figure Description

A winding rod 51 is rotatably arranged between the bearing seats 50. End shafts are provided at both ends of the winding rod 51. A side plate 53 is installed on one of the square tubes 4. One end shaft passes through the side plate 53. A rotating shaft 54 is provided at the upper end of the side plate 53. A drive wheel 55 is connected to the outer end of the rotating shaft 54 by a key. A handle is provided eccentrically on the drive wheel 55. A driven wheel 57 is provided on one of the end shafts. The driven wheel 57 and the drive wheel 55 are driven by a belt 56.
[0023] Optionally, a pair of screws 2 are threaded to both ends of the horizontal plate 1. A pair of slotted holes 30 are provided on the movable plate 3, and the screws 2 pass through the slotted holes 30. The lower end of the screw cap acts on the upper wall of the movable plate 3. An inner spline sleeve is rotatably provided at the lower end of the side plate 53. A limit ring is connected to the inner spline sleeve by a pin. The limit ring is located on the inner and outer sides of the side plate 53. The outer end of the inner spline sleeve is installed on the driven wheel 57 by a screw. The inner spline sleeve is sleeved on the end shaft located on the same side. A spline shaft 52 is provided at the outer end of the end shaft, and the inner spline sleeve is sleeved on the spline shaft 52.
[0024] A pair of diagonal bracing arms 8 are bolted to the lower extension plate 5. The outer ends of the diagonal bracing arms 8 extend downward at an angle. A scraper 80 is welded to the outer ends of the diagonal bracing arms 8. The lower end of the scraper 80 has a blade-shaped structure, and a baffle 81 is formed on the upper wall of the scraper 80.
[0025] The winding rod 51 has a V-shaped groove, and a retaining strip 7 is embedded in the V-shaped groove. The inner wall of the retaining strip 7 has multiple retaining teeth, and the outer wall of the retaining strip 7 has an arc-shaped structure. A pair of retaining grooves are opened at both ends of the retaining strip 7. Multiple capped pins 70 are provided at both ends of the winding rod 51. A protruding plate 71 is fitted on the capped pin 70. A retaining ring 72 is provided at the outer end of the protruding plate 71.
