[0001] This utility model relates to the field of cantaloupe cultivation, and in particular to a cantaloupe residual film recycling and tilling device. Background Technology

[0002] Mulch film is needed in the cultivation of Hami melons to retain moisture. While mulch film brings great benefits to Hami melon production, it also causes significant pollution to the soil and environment. The white pollution from the mulch film hinders crop growth, leading to reduced yields and greatly lowering farmers' income. Therefore, it is necessary to collect and clean up the mulch film left in the soil after the previous planting before sowing.

[0003] To address the problems raised in the background art, those skilled in the art have proposed a cantaloupe residual film recycling and tilling device. Utility Model Content

[0004] The purpose of this utility model is to provide a soil-turning and recycling device for cantaloupe seedlings, in order to solve the problem of white pollution caused by residual plastic film in the soil and affecting the next planting.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] like Figure 1 - Figure 6 As shown, this utility model provides a soil-plowing and soil-recycling device for cantaloupe, comprising a plow frame 10, which is fixedly mounted on a tractor. Multiple plow heads 20 are fixed on the plow frame 10 for tilling the soil. While tilling, the plow head can also uncover the plastic film buried in the soil. A film-cleaning assembly 40 is installed on the plow frame 10, including a film-scraping rod 41 rotatably connected to the plow frame 10. A film-collecting rake 30 is slidably inserted into the film-scraping rod 41. Multiple parallel hydraulic cylinders 43 are fixed on the plow frame 10. The piston rod of the hydraulic cylinder 43 is rotatably connected to the shaft of the film-collecting rake 30. The extension and retraction direction of the hydraulic cylinder 43 is set along the direction of travel of the tractor. The rotation axis of the film-scraping rod 41 is set perpendicular to the piston rod of the hydraulic cylinder 43. The extension and retraction of the piston rod of the hydraulic cylinder 43 can be used to adjust the tilt angle of the film-collecting rake 30. When a large amount of film is inserted on the film-collecting rake 30, the piston rod of the hydraulic cylinder 43 extends, and the film-scraping rod 41 rotates accordingly. The film-scraping rod 41 scrapes off the film on the film-collecting rake 30, thus completing the automatic cleaning of the film.

[0028] like Figure 2 , Figure 4 , Figure 5 As shown, the film-collecting rake 30 includes multiple straight rod-shaped rake rods 31. The film-scraping rod 41 has multiple first through holes 411 that are adapted to the rake rods 31, and the rake rods 31 are inserted into the first through holes 411.

[0029] Multiple hydraulic cylinders 43 are rotatably connected to mounting rods 44 via ear plates 442. The rake rod 31 is mounted on the mounting rod 44. Therefore, when the piston rod of the hydraulic cylinder 43 extends, the piston rod drives the ear plate 442 and the mounting rod 44 to move away from the plow head 20. At the same time, the scraping rod 41 rotates under the drive of the rake rod 31. The rake rod 31 moves upward at this time, and the distance between the lower end of the rake rod 31 and the scraping rod 41 gradually shortens. Thus, the rake rod 31 removes the plastic film that it has penetrated after passing the scraping rod 41.

[0030] After cleaning is completed, the piston rod of the hydraulic cylinder 43 retracts, causing the rake rod 31 to return to its original position.

[0031] like Figure 2 , Figure 3 , Figure 6As shown, multiple second through holes 441 adapted to the rake rod 31 are provided on the mounting rod 44. A tension spring 32 is fixedly connected to the top of the mounting rod 44 and the rake rod 31. When the rake rod 31 is inserted into the soil after being turned over, when the bottom of the rake rod 31 encounters a hard rock, the rake rod 31 moves upward under the obstruction of the rock, and the tension spring 32 is elastically stretched and generates an elastic contraction force. The rake rod 31 can slide into the second through hole 441, and with the cooperation of the tension spring 32, it can be buffered and slide upward when the rake rod 31 encounters a hard object, so as to avoid bending the rake rod 31.

[0032] like Figure 2 , Figure 3 As shown, brackets 42 are vertically slidably inserted on both sides of the plow frame 10. A locking screw 422 that abuts against the bracket 42 is threadedly connected to one side of the plow frame 10. The end of the scraping rod 41 is rotatably connected to the bracket 42 via the shaft 412. When the soil is compacted and hard, the bracket 42 is moved downward, causing the scraping rod 41 to move downward and adjusting the distance between the lower end of the rake rod 31 and the scraping rod 41 to be shorter. In this way, when the rake rod 31 moves in hard soil, the lever arm of the distance between the rake rod 31 and the scraping rod 41 is shorter, avoiding the rake rod 31 from bending.

[0033] When the soil is loose, the support 42 is adjusted upward and fixed by the locking screw 422. At this time, the distance between the rake rod 31 and the film scraping rod 41 becomes longer, thereby increasing the length of the film insertion of the rake rod 31 and reducing the number of times the film is cleaned.

[0034] It is worth noting that the harrow 31 and the plow head 20 are offset, thus avoiding interference with the plow head 20 when the harrow 31 is rotated and adjusted.

[0035] like Figure 2 As shown, by providing multiple positioning holes 421 on the bracket 42 that correspond to and are compatible with the locking screw 422, the locking screw 422 is screwed into the corresponding positioning hole 421 to improve the fixing reliability between the bracket 42 and the plow frame 10.

[0036] like Figure 4 , Figure 5 As shown, the rake handle 31 includes a handle portion 311 and a head portion 312, the head portion 312 being a frustoconical structure;

[0037] A limit switch 45 is fixedly installed on one side of the scraper rod 41. The contact of the limit switch 45 is inserted into the first through hole 411. The limit switch 45 is electrically connected to the hydraulic cylinder 43. When the rod 311 slides into the first through hole 411, the contact of the limit switch 45 is always in the pressed state. When the rod 311 is disengaged from the lower end of the first through hole 411, the contact of the limit switch 45 pops out. The limit switch 45 is mechanically triggered to convert the displacement signal into an electrical signal, which controls the solenoid valve to switch the oil circuit direction, thereby accurately starting, stopping or reversing the hydraulic cylinder 43, realizing the functions of stroke limit, automatic reciprocating or safety protection, and preventing the rod 311 from disengaging from the first through hole 411 due to excessive movement. At the same time, the head 312 facilitates the rod 311 to squeeze the contact of the limit switch 45 and facilitates the insertion and removal of the mulch film.

[0038] Working principle: Based on the soil hardness, loosen the locking screw 422 and then adjust the height of the scraping rod 41. Then, adjust the tilt angle of the rake rod 31 by extending and retracting the piston rod of the hydraulic cylinder 43 to ensure that the lower end of the rake rod 31 can be inserted into the soil after tilling.

[0039] The plow frame 10 is fixedly installed on the mounting frame of the tractor. Then, the plow head 20 is pulled by the tractor to turn the soil. After that, the multiple rakes 31 behind it are used to pick up or intercept and recycle the plastic film after turning the soil.

[0040] When the plastic film inserted on the rake bar 31 needs to be cleaned, the piston rod of the hydraulic cylinder 43 extends outward, causing the ear plate 442 and the mounting rod 44 to move accordingly, and pulling the rake bar 31 to move. At the same time, the rake bar 31 drives the scraping rod 41 to rotate around the shaft 412, and the scraping rod 41 cleans the plastic film inserted on the rake bar 31.

[0041] After cleaning is completed, the piston rod of the hydraulic cylinder 43 retracts, which allows the rake rod 31 to return to its original position.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
