Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly to a combined operation machine for straw crushing and residual film recycling. Background Art

[0002] Mulch film is used for ground covering of farmland, which has the functions of increasing soil temperature, maintaining soil moisture, maintaining soil structure, preventing pests from attacking crops and diseases caused by certain microorganisms. However, the pollution of residual mulch film is a major problem that China's agricultural sustainable development needs to face and solve. Mechanical recycling is an effective, direct and quick-result treatment technology.

[0003] At present, there are many existing residual film recycling devices. However, the existing residual film recycling devices are mainly traction-type residual film recycling devices, which generally can only complete the recycling and collection and packing of residual film, and cannot simultaneously complete the harvesting and crushing of straw. When actually recycling residual film, there are often crop straws remaining in the farmland. It is only possible to first complete the straw crushing and returning to the field through a separate device before the residual film can be recycled. The operation steps are numerous, the time consumption is long, the operation cost is high, and the stubble attached and entangled in the packed and recycled residual film is difficult to separate, which is not conducive to the later recycling and treatment of residual film.

[0014] Preferably, the packing mechanism includes an open-top box body. A plurality of rotating rollers are installed at the rear of the open-top box body, arranged in a ")" shape. At the front, there is a waste discharge auger and a plurality of belt rollers, on which an annular wide belt is covered. The waste discharge auger is located at the lower part of the frame. The structure of the waste discharge auger includes two auger sections with both turning outwards. There is an annular groove between the two auger sections. The structure of the annular wide belt includes a belt body. A plurality of bumps are evenly distributed on the upper surface of the belt body. At the middle position of the lower surface, there is a longitudinally extending downward convex guide strip; the guide strip is embedded in the annular groove, so that the annular wide belt winds around the belt rollers and the waste discharge auger; The waste discharge auger and a plurality of belt rollers at the front are arranged in a convex arc shape.

The front group of rollers consists of three rollers, arranged in a convex arc shape, and the rear group of rollers consists of six rollers arranged in an oblique straight line. The upper ends of the two groups of rollers are open, forming an entrance for residual film.

[0016] Preferably, in the above packing structure, a plurality of convex strips are axially arranged on the surface of the roller, which is beneficial to increasing the friction during packing.

[0017] Preferably, the straw crushing mechanism comprises a shell, in which a crushing and throwing knife device and a straw conveying auger are arranged. The crushing and throwing knife device includes a high-speed throwing knife shaft roller and a plurality of groups of throwing knives arranged at intervals on the shaft roller. The straw conveying auger is located behind the crushing and throwing knife device.

[0018] The working principle of the present invention: In the picking mechanism I of the present invention, the film-lifting teeth are installed on the surface of the film-lifting belt and evenly distributed on the film-lifting belt. The distance between the film-lifting teeth is about 200 mm. When the film-lifting belt bypasses the film-loosening and slag-discharging roller, the tip of the film-lifting tooth is 5-30 mm higher than the radius of the film-loosening and slag-discharging roller. When the film-lifting tooth bypasses the first film-removing roller, the tip of the film-lifting tooth is lower than the surface of the first film-removing roller. When the film-lifting tooth bypasses the second film-removing roller, the tip of the film-lifting tooth is lower than the surface of the second film-removing roller. The center of the first film-removing roller is offset 8-20 mm from the axis of the first film-removing roller, forming an eccentric disc. Each group of adjacent discs rotates 180 degrees or 120 degrees and is fixed on the shaft, so as to form a balance relationship between the discs. Since the roller disc in the first film-removing roller is an eccentric circle, a reciprocating motion is formed during the rotational motion, so as to better remove the film. The second film-removing roller is located below the first film-removing roller to perform a second film removal on the film not completely removed by the first film-removing roller. The film-loosening and slag-discharging roller also adopts the design of the first film-removing roller. Because the film-lifting tooth is higher than the surface of the film-loosening and slag-discharging roller, the film-loosening and slag-discharging roller does not push the residual film on the film-lifting tooth off when forming a reciprocating motion due to rotation. However, due to the vibration generated by the reciprocating motion of the film-loosening and slag-discharging roller, the entrained soil and impurities are easily shed.

[0019] In the picking mechanism II of the present invention, the film-lifting roller rotates close to the ground. When the film-picking belt rotates clockwise, it picks up the residual film on the ground surface. When the residual film turns to the film-lifting deep groove belt roller along with the film-picking belt, the row of film-removing belts rotating together will carry the residual film backward. When the residual film turns to the film-removing deep groove belt roller along with the film-removing belt, it will fall off backward on the film-removing deep groove belt roller and fall into the packing mechanism arranged behind for packing operation. When the film-removing belt bypasses the secondary film-removing roller located below the film-removing deep groove belt roller, the structure of the secondary film-removing roller is the same as that of the film-removing deep groove belt roller, and the residual film will further fall off twice.

[0020] The film picking belt and the film stripping belt are arranged alternately on the film picking deep groove belt roller, and the rotation directions of the film picking deep groove belt roller, the film stripping deep groove belt roller, the secondary film stripping roller, and the film picking roller are consistent. The film stripping belt can pass through the annular grooves of the film picking deep groove belt roller, the film stripping deep groove belt roller, and the secondary film stripping roller, and is supported by the film picking deep groove belt pulley roller, the film stripping deep groove belt pulley roller, and the secondary film stripping roller to perform a circumferential motion. The film picking belt is provided with film picking trapezoidal teeth on its surface, and when it performs a circumferential motion supported by the film picking deep groove belt roller and the film picking roller, the residual film can be conveniently picked up.

[0021] The slag removing brush is close to the film picking trapezoidal teeth on the film picking belt to shake off the soil and other impurities entrained by the residual film and enter the slag discharge auger. The slag removing brush makes it easy for the entrained soil and impurities to fall off and then be discharged through the slag discharge auger.

[0022] The film picking trapezoidal teeth are installed on the surface of the film picking belt and are evenly distributed on the film picking belt. The secondary film stripping roller is located below the film stripping deep groove belt roller to perform a second film stripping on the residual film that has not been completely stripped off in the film stripping deep groove belt roller.

[0023] In the picking mechanism III of the present invention, the picking roller rotates close to the ground, and when the conveyor belt rotates clockwise therewith, the residual film on the surface of the ground is picked up. When the residual film is transferred to the film stripping wheel along with the conveyor belt, the slag removal brush roller located on the front side uses the rotating brush plate to shake off the entrained mud and dust. The mud and dust will fall into the slag discharge auger below and be discharged to the outside of the main frame through the slag discharge auger. The residual film on the top will bypass the conveyor belt groove of the film stripping wheel along with the rows of conveyor belts rotating together, and the residual film will fall off to the rear. The high-pressure strong wind film stripping nozzle shoots strong wind directly at the conveyor belt to help blow the residual film to the rear, and the fallen residual film can be packaged at the back.

[0024] The film picking teeth are installed on the surface of the conveyor belt and are evenly distributed on the conveyor belt. The slag removing brush roller is close to the film picking teeth on the conveyor belt to shake off the soil and other impurities entrained by the residual film and enter the slag discharge auger. The slag removing brush roller makes it easy for the entrained soil and impurities to fall off, and then it is discharged to the outside of the main frame through the slag discharge auger.

[0025] In the packaging mechanism, the residual film that falls off to the rear side enters the open box, and the front wide annular belt passes over the debris removal auger at the bottom of the frame, and is embedded in the annular groove of the debris removal auger through the guide strips on the lower surface, so that it rotates stably, and the belt will not shift to one side of the debris removal auger; the structure of the debris removal auger consists of two auger sections that turn outward, and the wide annular belt rotates synchronously with the debris removal auger, and the separated small clods of soil, grass roots and other debris enter the interior of the auger, and the two auger sections transport the impurities to both sides respectively, and then throw the impurities into the field from the debris removal ports at the bottom or both sides of the main frame.

[0026] The multiple rollers at the rear are arranged in an oblique straight line or in a ")" shape, and cooperate with the ring-shaped wide belt at the front to pack the incoming residual film. As the residual film packing increases from small to large, the ring-shaped wide belt will become tighter. This packaging combination structure combining a ring-shaped wide belt with multiple groups of rollers is very suitable for the residual film packaging operation environment, and the structure is simple and practical.

[0027] Compared with the prior art, the combined operation machine for straw crushing and residual film recovery of the present invention has the following advantages: by utilizing the straw conveying auger in the front straw crushing mechanism, the ground can be cleaned relatively cleanly after the straw is crushed, thus providing a relatively clean ground foundation for the subsequent residual film picking operation; in the operation of the picking mechanism, the residual film can be effectively picked up, and the film can be removed once or twice by utilizing the film stripping roller, and the film stripping is clean and efficient; by utilizing the residual film slag removal mechanism, slag removal is performed before film stripping, so that most of the soil or straw fragments mixed in the residual film can be shaken off before film stripping, and the film stripping and slag removal are completed at one time, without the need to design an accompanying anti-blocking mechanism, and is particularly suitable for residual film recovery operations during the crop harvest season in Xinjiang, with good use effect, and can effectively reduce the impurities in the film stripping roller and the residual film, thereby achieving efficient residual film picking and recovery. The present invention performs the packing operation while picking up. During the operation of the packing circular wide belt, the sticky materials on the belt are not easy to stick to the outer surface of the belt roller, which effectively prevents the belt from sliding to one side and is not easy to be damaged. When applied to the process of packing residual film, the belt can effectively separate the debris entrained in the residual film, and then use the impurity removal auger to effectively discharge the impurities. This packaging combination structure combining the circular wide belt with multiple groups of rollers is very suitable for the residual film packing operation environment, and the structure is simple and practical. At the same time, the combined operation machine with the above-mentioned picking and packing mechanism is more suitable for the residual film packing operation environment, and has good baling and impurity removal effect, simple structure, and is economical and practical.

[0081] The film-forming bottom roller 3-1 is a smooth roller. The film-loosening slag-discharging roller 3-6 has the same structure as the first film-removing roller 3-3. Its structure includes a roller shaft 3-7, an eccentric roller I 3-8, and an eccentric roller II 3-10. The shaft holes of the eccentric roller I 3-8 and the eccentric roller II 3-10 are not at their central positions. The axial width of the eccentric roller II 3-10 is greater than that of the eccentric roller I 3-8. A plurality of the eccentric roller I 3-8 and the eccentric roller II 3-10 are fixedly arranged on the roller shaft, and the radial heights of adjacent rollers are arranged in a staggered manner. An annular groove I 3-9 is formed between the eccentric roller I 3-8 and the eccentric roller I 3-8 or between the eccentric roller I 3-8 and the eccentric roller II 3-10. The film-forming belt 3-4 is embedded in the annular groove I 3-9 and winds around. The structure of the second film-removing roller 3-2 is composed of a plurality of annular grooves II 3-11 arranged at intervals on a smooth roller. The axial widths of the annular grooves II 3-11 are set to be the same or different according to needs.

[0082] The depth of the annular groove I 3-9 on the film-loosening slag-discharging roller 3-6 is relatively shallow, and the film-forming teeth on the film-forming belt 3-4 should protrude from the annular groove I 3-9 on the film-loosening slag-discharging roller 3-6; the depth of the annular groove I 3-9 on the first film-removing roller 3-3 is relatively deep, and the tip height of the film-forming teeth on the film-forming belt 3-4 is lower than the upper surface of the annular groove I 3-9 on the first film-removing roller; the depth of the annular groove II 3-11 on the second film-removing roller 3-2 is relatively deep, and the tip height of the film-forming teeth on the film-forming belt 3-4 is lower than the upper surface of the annular groove II 3-11 on the second film-removing roller 3-2; The residual film slag-removing mechanism 11 mainly includes a slag-removing brush 8-2 and a slag-discharging auger 8-1. The slag-removing brush 8-2 is close to the film-loosening slag-discharging roller 3-6 and is used to shake off the soil in the residual film. The slag-discharging auger 8-1 is located below the slag-removing brush 8-2 and is used to transport the soil in the shaken-off residual film to one side of the main frame.

[0083] The shaft holes of the eccentric roller I 3-8 and the eccentric roller II 3-10 on the first film-removing roller 3-3 or the film-loosening slag-discharging roller 3-6 in the pick-up mechanism type I 3 are not at their central positions. They are eccentric roller discs, and the offset distance between the center of the shaft hole and the center of the roller disc is 8-20 mm.

[0084] When the eccentric roller I 3-8 and the eccentric roller II 3-10 on the first film-removing roller 3-3 or the film-loosening slag-discharging roller 3-6 in the pick-up mechanism type I 3 are installed and arranged, each group of adjacent roller discs is fixed on the roller shaft by rotating 180 degrees or 120 degrees, so as to form a balance relationship between the roller discs.

[0085] In the pick-up mechanism type I 3, the structures of the multiple film-lifting belts 3-4 arranged side by side are the same. The distance between adjacent film-lifting belts is adapted to the distance between adjacent corresponding annular grooves I 3-9 or the distance between adjacent annular grooves II 3-11 during winding; the shape of the film-lifting teeth 3-5 is a frustum shape. The tips of the film-lifting teeth 3-4 are 5-30 mm higher than the upper surface of the film-loosening and slag-discharging disc 3-6.

[0086] The packing mechanism 4 has a structure including an open-top box body 4-1. At the rear of the open-top box body 4-1, multiple rotating rollers 4-2 are installed, arranged in an inclined straight line. At the front, there is a waste-discharging auger 4-4 and multiple belt rollers 4-5, and an annular wide belt 4-3 is covered thereon. The waste-discharging auger 4-4 is located at the lower part of the frame. The structure of the waste-discharging auger 4-4 includes two auger sections with both turning directions facing outwards. There is an annular groove 4-7 between the two auger sections. The structure of the annular wide belt 4-3 includes a belt body. On the upper surface of the belt body, multiple bumps 4-8 are evenly distributed. At the middle position of the lower surface, there is a longitudinally extending downward convex guide strip 4-9; the guide strip 4-9 is embedded in the annular groove 4-7, so that the annular wide belt 4-3 winds around the belt rollers 4-5 and the waste-discharging auger 4-4.

[0087] The front waste-discharging auger 4-4 and multiple belt rollers 4-5 are arranged in a convex arc shape. The upper end of the open-top box body 4-1 is an open opening, forming a waste film inlet; the front waste-discharging auger 4-4 and multiple belt rollers 4-5 drive the annular wide belt 4-3 to rotate clockwise, and the multiple rotating rollers 4-2 arranged in an inclined straight line at the rear rotate clockwise driven by a chain.

[0088] On the surface of the rotating roller 3-2, multiple convex strips are axially provided, and the provided convex strips can increase the friction force during packing.

[0089] In this embodiment, in the straw crushing and residual film recycling combined operation machine provided by the present invention, for the picking-up mechanism I 3, the film-lifting teeth 3-5 are installed on the surface of the film-lifting belt 3-4 and are evenly distributed on the film-lifting belt 3-4. The distance between the film-lifting teeth 3-5 and the film-lifting teeth 3-5 is about 200 mm. When the film-lifting belt 3-4 bypasses the film-loosening slag-discharging disc 3-6, the tip of the film-lifting tooth 3-5 is 5-30 mm higher than the radius surface of the film-loosening slag-discharging disc 3-6. When the film-lifting belt 3-4 bypasses the first film-removing disc 3-3, the tip of the film-lifting tooth 3-5 should be lower than the surface of the first film-removing roller. When the film-lifting tooth bypasses the second film-removing disc 3-2, the tip of the film-lifting tooth should be lower than the surface of the second film-removing roller 3-2. The center of the first film-removing roller 3-3 is offset by 10 mm from the axis of the first film-removing roller, forming an eccentric disc. Each group of adjacent discs rotates 180 degrees or 120 degrees and is fixed on the shaft, so as to form a balance relationship between the discs. Since the roller disc in the first film-removing roller 3-3 is an eccentric circle, a reciprocating motion is formed during the rotation motion, so as to better remove the film. The second film-removing roller 3-2 is located below the first film-removing roller 3-3 and performs a second film removal on the film not completely removed by the first film-removing roller 3-3. The film-loosening slag-discharging roller 3-6 also adopts the design of the first film-removing roller. Because the film-lifting tooth is higher than the surface of the film-loosening slag-discharging roller 3-6, when the film-loosening slag-discharging roller 3-6 forms a reciprocating motion due to rotation, the residual film on the film-lifting tooth is not pushed off, but due to the shaking generated by the reciprocating motion of the film-loosening slag-discharging roller 3-6, the entrained soil impurities are easily shed. The structure of this embodiment is reasonable, economical and practical, and has a good use effect. The two-stage film removal is realized by using the picking-up structure type I 3, the film removal is clean and efficient, the film removal and slag discharge are completed in a flowing water manner at one time, there is no need to design an additional anti-blocking mechanism, the impurity content in the film-removing roller and the residual film can be effectively reduced, and the efficient picking-up and recycling of the residual film can be realized.

[0090] The residual film that falls backward from the picking-up mechanism enters the packing mechanism 4 at the rear for packing operation. In the packing mechanism 4, the front annular wide belt 4-3 bypasses the impurity-removing auger 4-4 at the lower part of the frame, and is embedded in the annular groove 4-7 of the impurity-removing auger 4-4 through the guide strip 4-9 on the lower surface, and rotates stably, and the belt will not shift and deviate to the side of the impurity-removing auger 4-4; the structure of the impurity-removing auger 4-4 is two auger sections with the turning directions both facing outwards. The annular wide belt 4-3 rotates synchronously with the impurity-removing auger 4-4, and the separated small soil blocks, grass roots and other sundries enter the inside of the auger. The two auger sections transport the impurities to both sides respectively, and then throw the impurities into the field from the impurity-removing ports arranged at the bottom or both sides of the main frame.

[0091] The multiple rear rollers 4-2 arranged in an oblique straight line cooperate with the front annular wide belt 4-3 to pack the incoming residual film. As the size of the residual film packing increases from small to large, the annular wide belt 4-3 will change from loose to tight. This packing combination structure of the annular wide belt 4-3 and multiple groups of rollers 4-2 is very suitable for the residual film packing operation environment, and the structure is simple and practical.

[0092] In the straw crushing and residual film recycling combined operation machine in this embodiment, the straw conveying auger in the front-mounted straw crushing mechanism is used. After the straw is crushed, the ground is relatively clean, providing a relatively clean ground basis for the subsequent residual film picking operation; during the operation of the picking mechanism, the residual film can be effectively picked up, and the stripping roller is used for secondary stripping, with high stripping efficiency and cleanliness; the residual film slag removal mechanism is used to remove slag before stripping, so that most of the soil or straw fragments mixed in the residual film can be shaken off before stripping, and the stripping and slag removal are completed in a flowing water manner at one time, which can effectively reduce the impurity content in the residual film and achieve efficient residual film picking and recycling. In the present invention, the packing operation is carried out while the picking operation is in progress. During the operation of the packing annular wide belt, the sticky materials on the belt are not easily adhered to the outer surface of the belt roller, effectively preventing the belt from sliding to one side and the belt from being easily damaged. When applied to the process of bundling residual film, the belt can effectively separate the impurities entrained in the residual film, and then the impurity discharge auger is used to effectively discharge the impurities. This packing combination structure of the annular wide belt and multiple groups of rollers is very suitable for the residual film packing operation environment, with a simple and practical structure.
