Description

Technical Field

[0001] This invention relates to the field of equipment technology for straw resource utilization, specifically to a straw screening and processing device. Background Technology

[0002] Straw is an important agricultural resource, and its comprehensive utilization is closely related to agricultural ecological environment protection. On the one hand, by effectively treating crop straw generated from agricultural activities, it can be reused as fertilizer or energy in agricultural production or other areas of social production, which can greatly improve the utilization efficiency of crop straw and enhance resource utilization. On the other hand, directly burning crop straw will cause serious pollution to the local ecological environment, damage soil structure, reduce soil fertility, and greatly affect the yield and quality of subsequent agricultural production.

[0003] Currently, the utilization of straw is limited. Comprehensive straw utilization includes returning it to the field as fertilizer, producing organic feed, and converting it into fuel. However, the main focus of comprehensive straw utilization is accelerating the decomposition process to achieve fertilizer conversion, with very little involvement in feed or fuel production. This fails to improve the efficiency of comprehensive straw utilization and maximize its economic, social, and ecological value. While some practical equipment exists for utilizing straw resources as animal feed, industrial materials, and industrial fuel / energy fermentation products, this equipment has high requirements for the quality of the straw used. Straw tissue consists of leaves, pith, and bark, and the utilization methods differ depending on the part of the straw. For animal feed, there are differences in palatability between ruminants and fermented straw, and different types and growth stages of straw have varying applicability. Utilizing straw as an industrial material or industrial fuel / energy fermentation product places even higher demands on the straw, significantly increasing utilization costs. Existing straw utilization equipment is insufficient to meet diverse usage conditions.

[0004] In the prior art, there are methods for detecting natural gas sulfides. For example, US Patent US20130281578A discloses a straw pith-splitting separation device and a method for plasticizing and granulating straw pith fibers. In this patented solution, straw is placed on a working platform and fed longitudinally, allowing it to pass through a saw blade and be gradually separated from the bottom side of the straw along its longitudinal direction. Then, the straw separated by the saw blade passes through a guide, causing it to separate along the slit created by the saw blade, thus exposing the pith in the straw. Finally, a brush connected to a brush shaft is driven to rotate together with the brush shaft. The invention involves using a rotating brush to remove the exposed pith from the separated stalks, thus separating the outer skin and pith. This invention primarily utilizes the cortical fiber layer of corn stalks as animal feed, employing a simple separation of the cortical fiber and central medulla for improved stalk utilization efficiency. However, while the separation method for corn stalks in this invention is relatively simple, it requires a high level of skill, resulting in poor separation of the cortical layer and medulla, low utilization efficiency, and difficulty in separating the different nutrient structures within the stalks. Furthermore, it is difficult to separate finer stalks such as wheat, leading to even lower utilization rates. Summary of the Invention

[0005] The purpose of this invention is to provide a straw screening and processing device to solve the problems of monotonous utilization methods of crop straw, difficulty in effectively separating and selecting the fiber structure of different parts of crop straw, and poor straw processing effect due to differences in crop plant growth results in the existing technology.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A straw screening and processing device includes an installation workbench. A conveying workbench and a slitting mounting frame are fixedly connected to the upper end of the installation workbench. The slitting mounting frame is located behind the conveying workbench. A slitting switching frame is slidably connected to the slitting mounting frame. A slitting motor is fixedly connected to the lower end of the slitting switching frame. A slitting cutter disc is rotatably connected to the lower end of the slitting switching frame. The slitting motor is powered by the slitting cutter disc. A conveying mounting platform is fixedly connected to the upper end of the installation workbench. The conveying mounting platform is located behind the conveying workbench. A conveying motor is provided on the upper side of the conveying mounting platform. A conveying main shaft roller is powered by the rear end of the conveying motor. A conveying base belt is rotatably connected to the front end of the conveying main shaft roller. A pressing conveyor belt is fixedly connected to the surface of the conveying base belt.

[0008] By setting up two sets of vertically distributed pressing conveyor belts, the straw can be forcibly transported and then cut, which improves the convenience of straw transport and cutting length control, improves the accuracy of cutting and separating different nutrient tissues of straw, improves the purity of straw selection and collection of different nutrient tissues, and improves the efficiency of straw cutting, screening and processing.

[0009] Preferably, the conveying mounting platform is provided with a conveying mechanism, which includes a positioning mounting plate fixedly connected to the upper surface of the conveying mounting platform. Two left and right distributed conveying mounting seats are fixedly connected to the upper surface of the positioning mounting plate. A gap adjustment seat is fixedly connected to the front surface of the conveying mounting seat. A conveying shaft sleeve is fixedly connected to the gap adjustment seat. A conveying main shaft roller is rotatably connected inside the conveying shaft sleeve. A conveying motor is fixedly connected to the rear surface of the conveying mounting seat.

[0010] By setting a conveyor motor to drive the pressing conveyor belt to rotate, the straw stem diameter is pressed and fixed in a relative position under the squeezing and cooperation of two sets of pressing conveyor belts for forced conveying. This can improve the reliability of straw conveying in straw processing and save straw recycling and processing time.

[0011] By setting up a conveyor mounting base, a gap adjustment base, and a conveyor shaft sleeve to cooperate with the pressing conveyor belt, the gap size can be adjusted to adapt to the conveying of straws with different stem diameters, which improves the adaptability and conveying stability when switching between different stem and root diameters for pressing and fixing the relative position of the straws.

[0012] Preferably, the upper end of the installation workbench is provided with a separation mechanism, and a separation mounting frame is fixedly connected to the upper surface of the installation workbench. The separation mounting frame is located on the rear side of the conveying workbench. The separation mechanism includes a separation slide frame that is slidably connected to the upper surface of the separation mounting frame. A separation motor is fixedly connected to the upper surface of the separation mounting frame. A separation screw is powered to the front end of the separation motor. The front end of the separation screw is rotatably connected to the separation slide frame. Two left and right distributed separation plunger cylinders are fixedly connected to the lower end of the separation slide frame. A separation telescopic rod is slidably connected to the lower end of the separation plunger cylinders. A scraper mounting plate is fixedly connected to the lower end of the separation telescopic rod. Two sets of front and rear cross-distributed cleaning scrapers are fixedly connected to the lower surface of the scraper mounting plate. The cleaning scrapers are located on the upper side of the conveying workbench.

[0013] By setting up a cleaning base, a scraper mounting plate, a cleaning gap frame, and a cleaning scraper, and cooperating with the straw roots being squeezed and fixed in the gap of the pressing conveyor belt, the stems and leaves are separated from the stem body, which improves the separation efficiency of straw stem body and stem leaves. It can classify and collect different nutrient tissues on the straw stem body for use, increase the diversity of straw resource utilization pathways, and reduce the cost of straw resource utilization.

[0014] By scraping and collecting stems and leaves by inserting the scraper downwards into the straw, the hard cortical fiber of the straw is destroyed. Combined with the pre-destruction by compression during the conveying process of two sets of pressing conveyor belts, the pre-destruction effect of the cortical fiber layer of the straw stem is further improved. This provides the conditions for destruction for the subsequent utilization of the straw cortical fiber layer structure of the stem and root, reducing the input of utilization work after the selection and separation of straw stem and root tissues and the difficulty of further refining the separation operation.

[0015] Preferably, a cleaning base is fixedly connected to the upper end face of the scraper mounting plate, a cleaning gap frame is fixedly connected to the lower end face of the cleaning base, and the cleaning gap frame is slidably connected to the lower end of the scraper.

[0016] Preferably, the upper end of the installation workbench is provided with a material preparation mechanism, which includes a feeding installation track, a feeding control seat, and an alignment hopper fixedly connected to the upper end of the installation workbench. The alignment hopper has a single-sided open material cavity. An alignment auxiliary plate is slidably connected to the upper end of the alignment hopper. A docking workbench is fixedly connected to the upper end of the feeding installation track. The height of the docking workbench is matched with the conveying workbench. A docking push plate is slidably connected between the alignment hopper and the docking workbench. The position of the docking push plate is matched with the gap between the two sets of pressing conveyor belts distributed vertically.

[0017] Preferably, a docking adjustment seat is fixedly connected to the right end of both the aligning hopper and the docking worktable. A docking guide plate is rotatably connected to the right end of the docking adjustment seat, and the orientation of the two docking guide plates is coordinated with the pressing conveyor belt.

[0018] Preferably, a feeding control motor is fixedly connected to the upper end face of the feeding control seat, a control spindle is powered to the front end of the feeding control motor, an offset crank wheel is fixedly connected to the front end of the control spindle, a push rod is rotatably connected to the offset crank wheel, a push slide is rotatably connected to the other end of the push rod, a docking push plate is fixedly connected to the push slide, and a docking push plate is slidably connected to the upper end of the docking worktable.

[0019] By setting up a control spindle, an offset crank wheel, a propulsion connecting rod, and a docking push plate, the efficiency of material preparation and conveying in straw recycling is improved, straw screening and processing time is saved, and the intensity of manual labor is reduced.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] See attached document Figure 1 To be continued Figure 3 As shown, the present invention provides a straw screening and processing device, including a mounting workbench 10. A conveying workbench 19 and a slitting mounting frame 15 are fixedly connected to the upper end of the mounting workbench 10. The slitting mounting frame 15 is located behind the conveying workbench 19, and its position and height are coordinated with the conveying workbench 19. A slitting switching frame 20 is slidably connected to the slitting mounting frame 15. A slitting motor 21 is fixedly connected to the lower end of the slitting switching frame 20. A slitting cutter disc 16 is rotatably connected to the lower end of the slitting switching frame 20. The slitting motor 21 is powered by the slitting cutter disc 16. The front end of the slitting mounting frame 15 slides along a guide rail. The switching frame 20 is fixed to the sliding stop position on the sliding mounting frame 15 by screw fastening. The upper end of the mounting workbench 10 is fixedly connected to the conveying mounting table 11, which is located behind the conveying workbench 19. The upper side of the conveying mounting table 11 is equipped with a conveying motor 57. The rear end of the conveying motor 57 is poweredly connected to the conveying spindle roller 56. The front end of the conveying spindle roller 56 is rotatably connected to the conveying base belt 59. The surface of the conveying base belt 59 is fixedly connected to the pressing conveyor belt 55. The pressing conveyor belt 55 can be a custom-formed conveyor belt that can be spliced ​​for easy installation of the outer structure.

[0037] When the two sets of pressing conveyor belts 55 are driven to rotate, the relative position of the straw is fixed by the squeezing action of the pressing conveyor belts 55 at the gap between the two sets of pressing conveyor belts 55 distributed vertically. The straw is then transported above the conveying worktable 19. After the straw is transported to the matching position of the slitting disc 16, the position of the slitting switching frame 20 on the slitting mounting frame 15 can be adjusted according to the slitting length. Then, the slitting motor 21 is started to drive the slitting disc 16 to rotate and slitting the transported straw. The squeezing action between the two sets of pressing conveyor belts 55 forces the straw to be transported, which can improve the convenience of straw transport and slitting length control, improve the accuracy of slitting and separating different nutrient tissues of straw, improve the purity of straw selection and collection of different nutrient tissues, and improve the efficiency of straw slitting and screening processing.

[0038] See attached document Figure 5 To be continued Figure 7 As shown, a conveying mechanism 50 is provided on the conveying mounting platform 11. The conveying mechanism 50 includes a positioning mounting plate 51 fixedly connected to the upper end face of the conveying mounting platform 11. Two left and right distributed conveying mounting seats 52 are fixedly connected to the upper end face of the positioning mounting plate 51. A gap adjustment seat 53 is fixedly connected to the front end face of the conveying mounting seat 52. A conveying shaft sleeve 54 is fixedly connected to the gap adjustment seat 53. A conveying main shaft roller 56 is rotatably connected inside the conveying shaft sleeve 54. A conveying motor 57 is fixedly connected to the rear end face of the conveying mounting seat 52.

[0039] The conveyor motor 57 drives the conveyor main shaft roller 56 to rotate, which in turn drives the conveyor base belt 59 and the pressing conveyor belt 55 to rotate. The straw stem diameter is pressed and fixed in a relative position between the two sets of pressing conveyor belts 55 for forced conveying. This can improve the reliability of straw conveying in straw processing and save straw recycling processing time.

[0040] The upper end of the conveyor mounting base 52 is provided with a hollow mounting groove. A mounting gathering block 58 is fixedly connected to the upper end face of the conveyor mounting base 52. The mounting gathering block 58 can fix the relative position of the side of the hollow groove of the conveyor mounting base 52 to improve the installation effect. The conveyor mounting base 52 is provided with mounting holes distributed on the left and right to adapt to the height adjustment of the pressing conveyor belt 55. The gap adjustment seat 53 can adjust the installation height on the conveyor mounting base 52 to adapt to the adjustment of the gap distance between the upper and lower sets of conveyor main shaft rollers 56. The pressing conveyor belt 55 can be made of a tough material to improve the pressing effect and transmission stability. According to the straw conveying guide specifications, the positions of the two conveyor mounting bases 52 are installed on the positioning mounting plate 51 to adapt to the adjustment of the tension force when the pressing conveyor belt 55 rotates. The distance between the two gap adjustment seats 53 is adjusted at the front end of the conveyor mounting base 52, thereby driving the longitudinal interval between the conveyor main shaft rollers 56 rotatably connected in the upper and lower conveyor shaft sleeves 54, thereby adjusting the gap size between the upper and lower sets of pressing conveyor belts 55.

[0041] Furthermore, when 57 drives 56 to rotate the two 59s located below, the root of the straw stem that enters the gap between the upper and lower sets of 55 is squeezed by the two 55s, thereby fixing the relative position of the straw stem and the contact point of the 55s. When 59 drives 55 to rotate, 55 drives the straw stem to move at the same linear speed. The two 55s and 59s located on the upper side drive the two 56s above to rotate in coordination to complete the straw conveying. This can adapt to the conveying of straw with different stem diameters due to different growth conditions, improves the adaptability and conveying stability of conveying straw with different stem root diameters by squeezing and fixing the relative position, and improves the efficiency of straw utilization and processing.

[0042] See attached document Figure 8 and attached Figure 9 As shown, the upper end of the installation workbench 10 is provided with a separation mechanism 70. A separation mounting frame 14 is fixedly connected to the upper end face of the installation workbench 10. The separation mounting frame 14 is located behind the conveying workbench 19. The separation mechanism 70 includes a separation slide frame 71 that is slidably connected to the upper end face of the separation mounting frame 14. A separation motor 72 is fixedly connected to the upper end face of the separation mounting frame 14. A separation screw 73 is powered to the front end of the separation motor 72. The front end of the separation screw 73 is rotatably connected to the separation slide frame 71. Two left and right distributed separation plunger cylinders 74 are fixedly connected to the lower end of the separation slide frame 71. A separation telescopic rod 75 is slidably connected to the lower end of the separation plunger cylinders 74. A scraper mounting plate 77 is fixedly connected to the lower end of the separation telescopic rod 75. Two sets of front and rear cross-distributed cleaning scrapers 80 are fixedly connected to the lower end face of the scraper mounting plate 77. The 80 is located on the upper side of 19.

[0043] The separating telescopic rod 75 is pneumatically or hydraulically extended within the separating plunger cylinder 74, causing the scraper mounting plate 77 and the cleaning scraper 80 to descend to a height position that aligns with the straw on the conveying table 19. The separating motor 72 drives the separating screw 73 to rotate, moving the motor 72 and the separating plunger cylinder 74 forward. This causes the cleaning scraper 80 to scrape and gather the stems and leaves from the straw stalks until the separating screw 73 drives the separating plunger cylinder 74, moving the cleaning scraper 80 to the top of the straw stalks on the conveying table 19. Then, the separating telescopic rod 75 is driven to further extend the separating rod. The piston cylinder 74 retracts, causing the scraper claw 80 to rise in height. Then, the separation motor 72 drives the separation screw 73 to reverse, causing the separation slide frame 71 and the scraper claw 80 to slide backward to the root of the straw stem for the next round of stem and leaf scraping. As the scraper claw 80 moves along the top of the straw stem, it works in conjunction with the straw root being squeezed and fixed in the gap of the pressing conveyor belt 55, separating the stem and leaves from the stem. This improves the efficiency and stability of the separation of the straw stem and leaves, and further enhances the convenience of separating and selecting different nutrient tissues of the straw stem and leaves for recycling.

[0044] See attached document Figure 9As shown, a cleaning base 76 is fixedly connected to the upper end face of the scraper mounting plate 77, and a cleaning gap frame 79 is fixedly connected to the lower end face of the cleaning base 76. The cleaning scraper 80 is slidably connected to the cleaning gap frame 79 at its lower end. The cleaning gap frame 79 is composed of a connecting frame fixing structure with a width smaller than the internal gap of the cleaning scraper 80, which is evenly arranged between two base frames with a spacing greater than the length of the scraper mounting plate 77 and which are matched thereto. After assembly, the internal connecting frame of the cleaning gap frame 79 slides up and down between the scraping gaps of the internal nail teeth of the cleaning scraper 80. It can slide up and down in the scraping gap channel inside the cleaning scraper 80, so that when the cleaning gap frame 79 moves downward, it pushes the straw material attached to the scraping gap of the cleaning scraper 80 away from the cleaning scraper 80.

[0045] Under the elastic force of the clearing spring 78, the clearing gap frame 79 slides to the lowest position between the gaps of the clearing scraper 80. When the clearing scraper 80 is inserted into the gap of the pressing conveyor belt 55 to squeeze the straw in a fixed position and perform the longitudinal movement of the straw stem to scrape the stem and leaves, the clearing gap frame 79 squeezes the clearing spring 78 under the reaction thrust of the straw and slides upward along the gap of the clearing scraper 80, without interfering with the work of the clearing scraper 80 inserting into the straw to perform the longitudinal movement and scraping of the stem and leaves.

[0046] After the stems and leaves are scraped, during the lifting process of the scraper 80, the elastic force of the scraper 78 causes the scraper gap frame 79 to move downward along the gap of the scraper 80, thereby pushing away the remaining attached stems and leaves inside the scraper 80. Then, the scraped and collected stems and leaves are piled up at the top of the straw. After being cut by the cutting disc 16, the top of the straw and the piled stems and leaves are collected by sliding down the second collection plate 18, which is fixedly connected to the front end of the conveyor table 19. The remaining stems at the root of the straw are collected by sliding down the first collection plate 17, which is fixedly connected to the right end of the conveyor table 19 and cooperates with the cutting disc 16, after being cut by the cutting disc 16.

[0047] It improves the separation effect of straw stems and leaves, enhances the smoothness and efficiency of straw stem and leaf separation and stacking, further improves the selection efficiency and separation effect of different nutrient tissues of straw stems and leaves, enables the classification and collection of different nutrient tissues on straw stems, increases the diversity of straw resource utilization pathways, and reduces the cost of straw resource utilization.

[0048] See attached document Figure 1 Appendix Figure 4 and appendix Figure 10As shown, the upper end of the installation workbench 10 is provided with a material preparation mechanism 30. The material preparation mechanism 30 includes a feeding installation rail 12, a feeding control seat 13, and an alignment hopper 31, which are fixedly connected to the upper surface of the installation workbench 10. The alignment hopper 31 has a single-sided open material cavity 37. An alignment auxiliary plate 32 is slidably connected to the upper end of the alignment hopper 31. A docking workbench 33 is fixedly connected to the upper end of the feeding installation rail 12. The height of the docking workbench 33 is matched with that of the conveying workbench 19. A docking push plate 34 is slidably connected between the alignment hopper 31 and the docking workbench 33. The position of the docking push plate 34 is related to the two sets of vertically distributed... The gaps between the pressing conveyor belts 55 are mutually coordinated; the alignment auxiliary plate 32 can collect the straw stems and roots evenly into the aligning hopper 31 for material preparation. Under the push of the push plate 34 at the bottom opening of the single-sided opening material cavity 37, the even stems in the single-sided opening material cavity 37 are pushed to slide on the docking worktable 33, and then squeezed and fixed in position at the gap between the pressing conveyor belts 55 before being conveyed. This improves the convenience of straw stem screening and cutting filling and the stability of material preparation, improves the efficiency of material preparation and conveying in straw recycling, and saves straw screening and processing time.

[0049] Both the aligning hopper 31 and the docking worktable 33 are fixedly connected to a docking adjustment seat 35 on their right ends. The docking adjustment seat 35 is rotatably connected to a docking guide plate 36 on its right end. The orientation of the two docking guide plates 36 is matched with that of the pressing conveyor belt 55. Adjusting the deflection angle of the docking guide plates 36 on the docking adjustment seat 35 can adapt to the gap width between the two pressing conveyor belts 55, which can improve the reliability of the straw being pushed into the pressing conveyor belt 55 by the docking push plate 34 in the single-sided open material cavity 37 and then docked in the channel, further improving the reliability of straw transmission.

[0050] A feeding control motor 91 is fixedly connected to the upper end of the feeding control seat 13. The front end of the feeding control motor 91 is powered by a control spindle 92. An offset crank wheel 93 is fixedly connected to the front end of the control spindle 92. A push rod 94 is rotatably connected to the offset crank wheel 93. The other end of the push rod 94 is rotatably connected to a push slide 95. The push slide 95 is fixedly connected to a docking push plate 34. The docking push plate 34 is slidably connected to the upper end of the docking worktable 33. When the feeding control motor 91 drives the control spindle 92 and the offset crank wheel 93 to rotate, the push rod 94 rotates periodically following the rotation of the offset crank wheel 93. This converts the rotation of the offset crank wheel 93 into the sliding of the push slide 95 on the docking worktable 33, which drives the docking push plate 34 to slide back and forth to push the straw for material preparation. This improves the reliability of straw material preparation and reduces the intensity of manual labor.

[0051] Example 2

[0052] Furthermore, during the utilization of the straw tissue after separation and selection of the stem and root structure, the scraper 80, when inserted downwards into the straw to scrape and collect the stems and leaves, has a destructive effect on the hard cortical fiber of the straw. Combined with the pre-destructive compression during the conveying process of the two sets of pressing conveyor belts 55, the pre-destructive effect of the straw stem cortical fiber layer is further improved. This provides the destructive conditions for the subsequent utilization of the straw cortical fiber layer structure of the stem and root, reducing the input of utilization work after the selection and separation of the straw stem and root tissue and the difficulty of further refining the separation operation.
