DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1-10 The present invention provides a corn straw processing device, including a processing box 1, a water removal mechanism 5 is arranged inside the processing box 1, the water removal mechanism 5 includes a first pressing roller 51 rotatably installed inside the processing box 1 and having the function of crushing the straw, and the outer surface of the first pressing roller 51 is equipped with a plurality of conical thorns for feeding, a first motor 52 is fixedly installed on the outer surface of the processing box 1, the output shaft of the first motor 52 is fixedly connected to the first pressing roller 51, and the outer surface of the first pressing roller 51 is provided with a groove for drainage.

[0040] Among them, when the straw is fed and crushed, the first thing that comes into contact is the first pressing roller 51. The first pressing roller 51 is rotated by the drive of the first motor 52. The multiple cone thorns installed on its outer surface not only play the role of feeding, that is, pushing the straw forward in the processing box 1, but also preliminarily crush and disperse the straw through the tips of the cone thorns, thereby increasing the contact area between the straw and the first pressing roller 51; at the same time, during the rotation process, the first pressing roller 51 uses its own weight and the driving force of the first motor 52 to apply pressure to the straw. This pressure acts on the straw and can effectively squeeze out the moisture contained in the straw. In addition, the outer surface of the first pressing roller 51 is specially provided with multiple grooves. These grooves not only increase the roughness of the surface of the first pressing roller 51 and increase the friction with the straw, thereby enhancing the pressurization effect, but also provide a smooth discharge channel for the squeezed out moisture; not only improves the efficiency of straw processing, but also provides a drier and easier-to-handle raw material for subsequent straw utilization, such as feed, biomass energy, etc.

[0041] In the technical solution of the embodiment of the present application, a pneumatic component 58 is provided inside the first pressure roller 51, and the pneumatic component 58 includes an air ring 581 for exhaust rotatably installed inside the first pressure roller 51, and the output shaft of the first motor 52 is fixedly installed with a third motor 587, and the output shaft of the third motor 587 is fixedly connected to the air ring 581. An air pump 585 is installed on the outer surface of the processing box 1, and the output end of the air pump 585 is connected to the first pressure roller 51 through the air ring 581. Drying rods 59 are installed between multiple air rings 581, and a through groove 584 is provided on the outer surface of the air ring 581. A plurality of exhaust holes 582 are provided on the surface of the first pressure roller groove, and a conical jet pipe 583 for pressurized jet action is installed between the through groove 584 and the exhaust hole 582.

[0042] Among them, by starting the first motor 52, the first motor 52 drives the first pressing roller 51 to rotate, and the first pressing roller 51 can continuously pressurize and feed the straw, and at the same time, the air ring 581 is driven to rotate by the third motor 587. At this time, the air pump 585 can rush the gas into the inside of the air ring 581 through the air guide pipe 586, and spray it along the conical jet pipe 583 inside the air ring 581 until it is connected through the exhaust hole 582 opened on the outer surface of the first pressing roller 51. At this time, the blocked debris in the groove is intermittently removed by the pressurized jet action, and the residual moisture in the straw is squeezed out again, which significantly improves the dehydration efficiency and ensures the stability of straw crushing. The straw after the moisture is discharged is easier to be crushed into fine particles for returning to the field; the drying rod 59 can dry the inside of the first pressing roller 51 to prevent the residual moisture in the air from corroding and damaging the air ring 581, thereby causing the air ring 581 to become stuck and affecting the straw dehydration efficiency.

[0043] In other instances, a second pressure roller 54 is provided inside the processing box 1 near the first pressure roller 51, a movable frame 55 is slidably installed at the top of the processing box 1, the second pressure roller 54 is rotatably installed on the inner wall of the movable frame 55, a second motor 53 is fixedly installed on the outer surface of the movable frame 55, the output shaft of the second motor 53 is fixedly connected to the second pressure roller 54, an electric push rod 56 is fixedly installed on the top of the processing box 1, the output end of the electric push rod 56 is fixedly connected to the movable frame 55, and a feed plate 2 is installed at one end of the processing box 1 near the first pressure roller 51 and the second pressure roller 54.

[0044] Among them, by starting the electric push rod 56, the electric push rod 56 drives the movable frame 55 to move, and the movable frame 55 drives the second pressing roller 54 to move, so that the distance between the second pressing roller 54 and the first pressing roller 51 can be adjusted, so that when the straw is compacted, the crushing pressure can be flexibly adjusted to avoid excessive crushing and jamming of coarse or thin straw or poor squeezing and water removal effect due to excessive crushing. The adjustable distance between the second pressing roller 54 and the first pressing roller 51 allows for flexible adjustment according to the humidity, type and crushing requirements of the straw to achieve the best crushing effect.

[0045] In other instances, a pushing assembly 57 is provided on the surface of the movable plate, and the pushing assembly 57 includes a limiting plate 571 fixedly mounted inside the movable frame 55, and the limiting plate 571 slides through the top of the processing box 1, and a plurality of pushing blocks 572 are fixedly mounted on the surface of the limiting plate 571 near the second pressure roller 54, and the pushing blocks 572 are inserted into grooves on the surface of the second pressure roller 54.

[0046] Among them, when the spacing of the second pressing roller 54 is adjusted by the movable frame 55, the movement of the limiting plate 571 can increase the stability of the movement of the second pressing roller 54, ensuring that the second pressing roller 54 can pressurize and drain the straw together with the first pressing roller 51 within a certain space. At the same time, by arranging a push block 572 on the surface of the movable frame 55, the push block 572 can clean the surface of the second pressing roller 54 from debris, avoiding straw debris from being stuck on the surface of the second pressing roller 54, affecting the adjustment of the second pressing roller 54 and the variable pressure drainage effect of the second pressing roller 54.

[0047] In other instances, a filtering mechanism 6 is provided inside the processing box 1, and the filtering mechanism 6 includes a support plate 62 installed inside the processing box 1. A filter screen 61 for filtering the water source is fixedly installed on the surface of the support plate 62 close to the first pressure roller 51. One end of the filter screen 61 and the support plate 62 are connected and a mounting plate 63 is installed. A drainage cavity is provided inside the mounting plate 63 for discharging the filtered liquid.

[0048] Among them, by arranging an arc-shaped filter screen 61 at the bottom end of the first pressing roller 51, the straw and the discharged water are effectively separated, so that the straw after pressurized drainage can be stably subjected to subsequent crushing treatment, thereby avoiding secondary absorption of the straw by the pressurized discharged water; by arranging a support plate 62 at the bottom end of the filter screen 61, not only can the filter screen 61 be supported, but also the pressurized water can be discharged for subsequent treatment through the drainage cavity inside the connecting mounting plate 63, thereby avoiding secondary pollution to the environment.

[0049] In other instances, a quantitative component 64 is provided inside the processing box 1, and the quantitative component 64 includes an air cylinder 642 installed inside the processing box 1, a piston 643 is provided inside the air cylinder 642, a moving rod 644 is fixedly installed on the surface of the piston 643, the free end of the moving rod 644 is fixedly connected to the mounting plate 63, and an exhaust groove 645 is provided on the surface of the moving rod 644, a connecting pipe 641 is installed between one end of the air cylinder 642 and the air guide pipe 586, a load-bearing wheel 646 is rotatably installed at the bottom end of the filter screen 61 for monitoring the degree of debris accumulation on the surface of the filter screen 61, a slide plate 648 for connecting the connecting pipe 641 is slid through the connecting pipe 641, a top rod 647 is installed between the slide plate 648 and the load-bearing wheel 646, and a collection box 65 is installed in communication with the bottom end of the processing box 1.

[0050] Among them, when the pressurized moisture of the straw is filtered and discharged through the filter screen 61, debris will accumulate on the surface of the filter screen 61. At this time, the filter screen 61 will undergo load-bearing deformation, and the load-bearing wheel 646 at the bottom end of the filter screen 61 will be pushed to move. The load-bearing wheel 646 will drive the top rod 647 to move, and the top rod 647 will drive the slide plate 648 to move. At this time, the air flow output by the air pump 585 can be introduced into the interior of the air cylinder 642 through the connecting pipe 641, so that the moving rod 644 is pushed to move through the piston 643, and the moving rod 644 drives the mounting plate 63 to move, and the mounting plate 63 drives the filter screen 61 to move out. At this time, the debris blocking the surface of the filter screen 61 will be scraped and fall into the collection box 65, and then the filter screen 61 is manually returned to its place, so as to continuously achieve the filtering effect of the filter screen 61.

[0051] In other instances, a crushing mechanism 3 is provided inside the processing box 1, and the crushing mechanism 3 includes a first crushing roller 37 and a second crushing roller 35 rotatably installed inside the processing box 1, and a first gear 32 and a second gear 34 are rotatably installed on the outer surface of the processing box 1, and the first gear 32 and the second gear 34 are engaged, and the first gear 32 is fixedly connected to one end of the first crushing roller 37, and the second gear 34 is fixedly connected to one end of the second crushing roller 35, and a driving motor 33 is fixedly installed on the outer surface of the processing box 1, and the output shaft of the driving motor 33 is fixedly connected to the first gear 32, and a protective box 31 is fixedly installed on the outer surface of the processing box 1, and the first gear 32 and the second gear 34 are both located inside the protective box 31.

[0052] Among them, after the straw is pressurized and drained, the drive motor 33 is started, and the drive motor 33 drives the first gear 32 to rotate, and the first gear 32 drives the second gear 34 to rotate, thereby synchronously driving the first crushing roller 37 and the second crushing roller 35 to rotate, thereby realizing the straw crushing process and exporting the crushed straw. Due to the synchronous rotation and mutual cooperation of the first crushing roller 37 and the second crushing roller 35, the straw can be subjected to uniform and continuous squeezing and cutting when passing through the crushing mechanism 3, which not only ensures that the particle size of the crushed straw is uniform, but also improves the crushing quality.

[0053] In some other examples, a guide plate 36 is fixedly installed inside the processing box 1. The guide plate 36 is located between the first crushing roller 37 and the second crushing roller 35. The cross section of the guide plate 36 is diamond-shaped.

[0054] Among them, by providing a guide plate 36, the guide plate 36 guides the flow direction of the crushed straw, which not only avoids blockage between the first crushing roller 37 and the second crushing roller 35, making it difficult to transport and crush the straw, but also can separate the straw, thereby reducing the crushing pressure between the first crushing roller 37 and the second crushing roller 35 and increasing the crushing effect.

[0055] In other instances, a baffle 38 is fixedly installed on the inner wall of the processing box 1 near the first crushing roller 37 and the second crushing roller 35. The first crushing roller 37 and the second crushing roller 35 include spiral blades installed on their outer surfaces, and the cross-section of the spiral blade is a triangular blade 372 with a triangular shape. A grinding block 371 is fixedly installed on the surface of the baffle 38 near the triangular blade 372, and the triangular blade 372 slides inside the grinding block 371.

[0056] Among them, the first crushing roller 37 and the second crushing roller 35 and the spiral blades on their surfaces realize efficient crushing of straw. At the same time, the spiral blades used can also discharge the crushed debris along the spiral groove to reduce the accumulation of debris. The blades are also continuously polished by the grinding block 371, so that the spiral blades are always kept sharp, the crushing effect is improved, and the service life of the equipment is extended.

[0057] In other examples, a backfill mechanism 4 is provided at one end of the processing box 1 away from the crushing mechanism 3 . The backfill mechanism 4 includes a flip auger rotatably installed at the rear end of the processing box 1 .

[0058] Among them, the setting of the flip auger allows the crushed straw to be stably backfilled into the field, realizing the recycling of straw, which not only reduces straw waste but also improves soil fertility.

[0063] Step 4: The compacted straw continues to move to the filter 61, where the filter 61 separates the straw from the water, and the filtered water is discharged from the processing box 1 through the drainage cavity;

[0064] Step 5: After the water is removed, the straw is fed between the first crushing roller 37 and the second crushing roller 35, crushed by the spiral blades, and guided by the guide plate 36 to the next processing link;

[0065] Step 6: The crushed straw continues to move to the tail of the processing box 1, and the turning auger is started to backfill the straw into the field.
