[0002] At present, in order to improve the yield of crops, the plastic film mulching cultivation technology is applied to the field of crop planting. The plastic film mulching cultivation technology mainly covers the ground with a transparent plastic film, sows seeds under the film and protects the growth of crop seedlings.

[0003] However, after the crops are harvested, some residual films will remain in the soil. These residual films will pollute the soil and the surrounding environment, and it is necessary to recycle the residual films. At present, the more commonly used residual film recycling equipment mainly drives the spike teeth to do circular motion through a conveyor belt. During the movement of the spike teeth, the residual films will be punctured. The punctured residual films will move along with the spike teeth, realizing the recycling of the residual films from the soil. However, the residual films hanging on the spike teeth cannot be conveniently discharged from the spike teeth for recycling, resulting in a poor residual film recycling effect.

[0004] Therefore, there is an urgent need for a residual film recycling machine with good residual film recycling effect. Summary of the Invention

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The purpose of the present invention is to provide a residual film recycling machine to solve the problems existing in the prior art. By using the cooperation of the residual film de-nailing wheel and the ring conveyor belt, the residual film can be automatically removed from the picking-up nails, improving the recycling effect of the residual film.

[0031] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Please refer to as Figures 1 to 6As shown in the figure, a residual film recycling machine is provided, which includes a frame 1, a residual film picking-up mechanism 2, and a residual film recycling mechanism 3. The residual film picking-up mechanism 2 includes a driving roller group, a residual film de-nailing wheel 7, and a plurality of annular conveyor belts 6. The driving roller group is arranged on the frame 1, and the plurality of annular conveyor belts 6 are all sleeved on the driving roller group. The annular conveyor belts 6 are driven by the driving roller group to rotate. A plurality of picking nails 8 are arranged at intervals along the conveying path of the annular conveyor belts 6. The driving roller group includes a first driving roller 4 and at least one second driving roller 5. One of the rollers serves as the driving roller, and the rest of the rollers serve as the driven rollers. The first driving roller 4 is higher than the second driving roller 5, and the first driving roller 4 is located behind the second driving roller 5 along the moving direction of the frame 1. A plurality of residual film de-nailing wheels 7 are arranged at intervals on the first driving roller 4. A de-nailing groove matching the annular conveyor belt 6 is formed between adjacent residual film de-nailing wheels 7. The depth of the de-nailing groove is not less than the total height of the annular conveyor belt 6 and the picking nails 8. The residual film recycling mechanism 3 is located behind the first driving roller 4 along the moving direction of the frame 1. When the picking nails 8 drive the residual film to the position of the residual film de-nailing wheel 7, the residual film will be blocked by the residual film de-nailing wheel 7 and gradually separated from the picking nails 8. The separated residual film can automatically enter the residual film recycling mechanism 3 under the influence of gravity, improving the recycling effect of the residual film.

[0033] When there are two or more second driving rollers 5, one of the second driving rollers 5 can be arranged below and in front of the first driving roller 4 along the moving direction of the frame 1. A plurality of auxiliary de-nailing wheels 9 are arranged at intervals along the axial direction of this driving roller. Another second driving roller 5 is located directly below the second driving roller 5 provided with the auxiliary de-nailing wheels 9 or below and in front of it along the moving direction of the frame 1. A groove body matching the annular conveyor belt 6 is formed between adjacent auxiliary de-nailing wheels 9. The depth of the groove body can be less than, equal to, or greater than the total height of the annular conveyor belt 6 and the picking nails 8, playing a role in assisting the separation of the residual film. Even if the depth of the groove body is equal to or greater than the total height of the annular conveyor belt 6 and the picking nails 8, due to the upward inclined plane between this second driving roller 5 and the first driving roller 4, the residual film will continue to move under the rotational action of the auxiliary de-nailing wheels 9 and the carrying action of the picking nails 8 between this second driving roller 5 and the first driving roller 4.

[0034] In this embodiment, the residual film recycling mechanism 3 includes a first winding conveyor belt 10 and a second winding conveyor belt 11. The first winding conveyor belt 10 and the second winding conveyor belt 11 are arranged in a V shape with the opening facing the first driving roller 4. The conveying directions of the first winding conveyor belt 10 and the second winding conveyor belt 11 are the same. A receiving bin for accommodating the residual film is formed among the first winding conveyor belt 10, the second winding conveyor belt 11, and the frame 1. When the residual film falls into the receiving bin, the two sides of the residual film are actually subjected to forces in opposite directions, thereby realizing the automatic winding and bundling of the residual film, reducing the space occupation and facilitating the subsequent transportation of the residual film; in other embodiments, the residual film recycling mechanism 3 can be a box or other containers.

[0035] Anti-slip settings can be applied to the belt bodies of the first bale conveyor belt 10 and the second bale conveyor belt 11. Anti-slip patterns can be set, or the roughness of the belt bodies can be increased. The anti-slip belt bodies can drive the residual film to wind into bales in the storage bin better.

[0036] The second bale conveyor belt 11 is located behind the first bale conveyor belt 10 along the moving direction of the frame 1. The end of the driving roller of the second bale conveyor belt 11 is rotatably arranged on the mounting plate 12. The mounting plate 12 is rotatably connected to the frame 1. The rotating shaft of the mounting plate 12 and the frame 1 is coaxially arranged with the driving roller of the second bale conveyor belt 11. Specifically, the driving roller can be set to rotate on both the mounting plate 12 and the frame 1. A first telescopic mechanism 13 is hinged on the frame 1. The end of the first telescopic mechanism 13 away from the frame 1 is hinged to the mounting plate 12. The first telescopic mechanism 13 can be an electric / pneumatic / hydraulic telescopic rod. Through the telescopic movement of the first telescopic mechanism 13, the opening or closing of the second bale conveyor belt 11 can be controlled. After opening, the residual film inside can be taken out conveniently. In this embodiment, the second bale conveyor belt 11 includes two driving rollers, one of which is a driving roller and the other is a driven roller. The driving roller is arranged above the driven roller, and the driving roller is coaxially arranged with the rotating shaft of the mounting plate 12 and the frame 1.

[0037] The residual film recycling machine further includes a straw returning knife shaft 14. The straw returning knife shaft 14 is located in front of the residual film picking-up mechanism 2 along the moving direction of the frame 1. The straw returning knife shaft 14 can first crush the straw and other sundries, reduce the influence of the straw and other sundries on the subsequent work of picking up the residual film, and at the same time break the residual film into strips and remove the soil covering and root stubbles on the surface of the residual film to facilitate the picking-up nails 8 to pick up the residual film, further improving the recycling effect of the residual film.

[0038] The residual film recycling machine further includes a first spiral conveyor shaft 15. The first spiral conveyor shaft 15 is located above the rear side of the straw returning knife shaft 14 along the moving direction of the frame 1. A conveying cylinder 16 is arranged on the outer peripheral side of the first spiral conveyor shaft 15. A baffle 17 is arranged on the frame 1. A guiding plate 18 is arranged between the first spiral conveyor shaft 15 and the straw returning knife shaft 14. A guiding channel 19 for the straw and sundries broken and lifted by the straw returning knife shaft 14 to pass through is formed between the guiding plate 18 and the baffle 17. The conveying cylinder 16 is communicated with the guiding channel 19. Both the first spiral conveyor shaft 15 and the conveying cylinder 16 extend to the outside of the working area of the annular conveyor belt 6. The straw returning knife shaft 14 rotates to crush the straw and lift the crushed straw. This part of the straw enters the guiding channel 19 and is guided into the conveying cylinder 16, and then is conveyed by the first spiral conveyor shaft 15 to the outside of the working area of the annular conveyor belt 6, further reducing the influence on the subsequent work of picking up the residual film.

[0039] An outlet can be opened at the bottom of the part where the conveying cylinder 16 extends out of the working area of the annular conveyor belt 6 for discharging the straw and sundries.

[0040] A first rolling press roller 20 is arranged behind the straw returning cutter shaft 14 along the moving direction of the frame 1 to achieve the shaping of the land.

[0041] A second spiral conveyor shaft 22 for loosening the land is arranged behind the first rolling press roller 20 along the moving direction of the frame 1 to loosen the shaped soil, facilitating the subsequent picking nails 8 to take out the residual film from the soil.

[0042] A second rolling press roller 21 is arranged behind the residual film picking mechanism 2 along the moving direction of the frame 1, which can achieve the shaping work of the soil after the residual film is recycled.

[0043] In this embodiment, a gear 23 is arranged on the frame 1, and the gear 23 is in transmission connection with the driving device. The driving device can be the rear output shaft of a tractor. The rear output shaft of the tractor is transmitted to the gear 23 through a universal joint drive shaft. The first driving roller 4 or the second driving roller 5 is in transmission connection with the gear 23 by means of a chain or a belt, etc. The movement source of other mechanisms that need to move mentioned in the text can also be the gear 23, such as the straw returning cutter shaft 14, the first spiral conveyor shaft 15, the second spiral conveyor shaft 22, the first rolling press roller 20, the second rolling press roller 21, the first bale conveyor belt 10 and the second bale conveyor belt 11.

A walking depth-limiting wheel 25 is arranged at the end of the connecting rod 24 far away from the frame 1. A second telescopic mechanism 26 for adjusting the rotation angle of the connecting rod 24 is hinged between the connecting rod 24 and the frame 1. The second telescopic mechanism 26 can be an electric / pneumatic / hydraulic telescopic rod. By controlling the telescopic of the second telescopic mechanism 26, the swing of the walking depth-limiting wheel 25 on the frame 1 can be realized, and the height of the frame 1 and the structures connected to the frame 1 can be controlled.

[0045] In this embodiment, the frame 1 includes two parallel side plates 28 and a traction frame 27. Each component is arranged between the two side plates 28. The traction frame 27 is connected to the two side plates 28, and the traction frame 27 is used for connecting with the traction device.

[0046] During the actual use process, first, the straw returning cutter shaft 14 is used to crush the straw, weeds and other sundries. The crushed and lifted straw and sundries are conveyed to one side by the first spiral conveyor shaft 15. After the soil with crushed straw and sundries passes through the shaping and loosening of the first rolling press roller 20 and the second spiral conveyor shaft 22 in sequence, it is inserted by the picking nails 8 of the residual film picking mechanism 2. The picking nails 8 take out the residual film and drop it at the residual film nail-removing wheel 7 and fall between the first bale conveyor belt 10 and the second bale conveyor belt 11 to be automatically wound into a bale.
