DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-10The 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 to move 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, increase the friction with the straw, thereby enhancing the pressurization effect, but also provide a smooth discharge channel for the squeezed 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 arranged inside the first pressure roller 51, and the pneumatic component 58 includes an air ring 581 for exhausting which is rotatably installed inside the first pressure roller 51, and a third motor 587 is fixedly installed on the output shaft of the first motor 52, and the output shaft of the third motor 587 is fixedly connected to the air ring 581, and 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, and a drying rod 59 is installed between the multiple air rings 581, and a through groove 584 is opened on the outer surface of the air ring 581, and a plurality of exhaust holes 582 are opened on the surface of the 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 third motor 587 drives the air ring 581 to rotate. At this time, the air pump 585 can rush the gas into the inside of the air ring 581 through the through groove 584, 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 water removal 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 interior of the first pressing roller 51 can be dried by the drying rod 59 to prevent the residual moisture in the air from corroding and damaging the air ring 581, thereby causing the air ring 581 to jam and affect the straw water removal 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 of coarse or thin straw, which may cause jamming, or excessive crushing of the straw, which may cause poor squeezing and water removal effect. The adjustable distance between the second pressing roller 54 and the first pressing roller 51 allows 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 installed 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 installed on the surface of the limiting plate 571 close to the second pressure roller 54, and the pushing blocks 572 are inserted in 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, a push block 572 is arranged on the surface of the movable frame 55, and the push block 572 can clean the surface of the second pressing roller 54 from debris, so as to avoid straw debris 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.

[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 support plate 62 be supported, but also the pressurized water can be discharged through the drainage cavity inside the connecting mounting plate 63 for subsequent treatment, 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 top rod 647, 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 slidably penetrated on the connecting pipe 641, a top rod 647 is installed between the slide plate 648 and the load-bearing wheel 646, and a collecting box 65 is installed at 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 of the filter screen 61 will be pushed to move, and 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 airflow 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 blocked on the surface of the filter screen 61 will be scraped and dropped 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.

[0052] Among them, after the straw is pressurized and drained, the drive motor 33 is started, the drive motor 33 drives the first gear 32 to rotate, 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, so as to realize the straw crushing process and export 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 uniformly and continuously squeezed and cut 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 a rhombus.

[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, which makes 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.
