DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment 1: Reference Figure 1-Figure 4 , a crop straw conveying device, comprising: a conveying component, a dust collecting component and a scattering component; The conveying assembly is used for continuously conveying straw in batches, and the conveying assembly includes a fixed base 1 and a scattering box 2 fixedly connected to the top of the fixed base 1; The dust collecting assembly is used to discharge and collect the dust and straw debris inside the scattering box 2. The dust collecting assembly includes a bellows 8 fixedly connected to one side of the scattering box 2 and a filter 12 fixedly arranged inside the bellows 8 and fixedly connected to the side wall of the scattering box 2; In addition, a second motor 13 is fixedly connected to the interior of the bellows 8, a driving end of the second motor 13 is fixedly connected to a rotating shaft 14, an exhaust fan 15 is fixedly connected to the rotating shaft 14, a dust delivery pipe 16 is fixedly connected to the side of the bellows 8 away from the scattering box 2, and a dust collection bag 17 is fixedly connected to the side of the ash delivery pipe 16 away from the bellows 8; The top of the bellows 8 is fixedly connected with a second fixing box 11, and the second fixing box 11 and the inside of the scattering box 2 are jointly provided with a buffer component for buffering the straw and vibrating and screening out dust; The dispersing assembly is used to disperse and transport the mixed and entangled straw bales, and the dispersing assembly includes two first reciprocating screws 26 rotatably connected to the inner walls of both sides of the dispersing box 2 and two second reciprocating screws 27 rotatably connected to the inner walls of both sides of the dispersing box 2 and adjacent to one side of the two first reciprocating screws 26; The dust collecting component and the scattering component are connected to each other through a transmission component; In this embodiment, the second motor 13 is started first, and the driving end of the second motor 13 drives the rotating shaft 14 to rotate, and the exhaust fan 15 fixedly connected to the rotating shaft 14 starts to rotate at high speed. At this time, a suction force will be formed inside the bellows 8, and the air containing dust and straw debris in the scattering box 2 will flow toward the bellows 8 under the action of the suction force. When the air enters the bellows 8 with dust and debris, it will first pass through the filter 12 fixedly connected to the inside of the bellows 8 and fixedly connected to the side wall of the scattering box 2. The filter 12 can effectively intercept the straw and only allow dust and fine debris to pass through, thereby achieving preliminary separation and screening. The dust and debris filtered by the filter 12 will continue to flow with the airflow and enter the dust bag 17 fixedly connected to the other side of the ash delivery pipe 16 through the ash delivery pipe 16. The dust bag 17, with its own good containment and filtering performance, firmly collects the dust inside to prevent it from escaping again; Furthermore, the filter 12 can effectively block the straw, allowing only dust and small debris to pass through, thus preventing the straw from being mistakenly sucked into the dust collection system and causing waste or blockage. The dust and debris filtered by the filter 12 will enter the dust collecting bag 17 through the ash delivery pipe 16 along with the airflow. The dust collecting bag 17 has good containment and filtering performance, and can firmly collect the dust inside to prevent it from escaping again, thereby achieving efficient discharge and collection of dust and straw debris. In this way, the air environment of the entire working area can be kept clean, reducing the harm of dust to the respiratory tract of operators, etc., and also making the subsequent straw purer. Whether it is used for biomass power generation, papermaking or other processing purposes, it can provide better quality raw materials, which guarantees the efficient development of subsequent production links from the source.

[0019] Embodiment 2: Reference Figure 3-Figure 7 and Fig. 9 and Fig.10 Compared with the first embodiment, the transmission assembly in this embodiment includes two first fixed boxes 9 fixedly connected to both sides of the bellows 8, and the two sides of the two first fixed boxes 9 are respectively fixedly connected with a transmission box 10, the first fixed box 9 is internally rotatably connected with a first bevel gear 18, the first bevel gear 18 is connected to the rotating shaft 14 through a first synchronous belt 19, the first fixed box 9 is internally rotatably connected to a side adjacent to the first bevel gear 18 with a second bevel gear 20, the transmission box 10 is internally rotatably connected with a first gear 21 fixedly connected to a first reciprocating screw 26, the transmission box 10 is internally rotatably connected with a synchronous shaft 22 fixedly connected to a second reciprocating screw 27, the transmission box 10 is internally rotatably connected with a second gear 23 on one side adjacent to the first gear 21, the second bevel gear 20 is connected to the first gear 21 through a second synchronous belt 24, and the second gear 23 is connected to the synchronous shaft 22 through a third synchronous belt 25.

[0020] Two breaking plates 28 are fixedly connected inside the breaking box 2 and located above the two first reciprocating screws 26 and the two second reciprocating screws 27. A number of slide grooves 29 are provided on the two breaking plates 28. Slide blocks 30 are threadedly sleeved on the two first reciprocating screws 26 and the two second reciprocating screws 27. The tops of the four slide blocks 30 are fixedly connected to fixed plates 31. The four fixed plates 31 are slidably connected to four first slide bars 32. The four first slide bars 32 are arranged as a group of four groups in total. The tops of the four groups of first slide bars 32 are fixedly connected to inclined plates 33. Four first springs 34 are fixedly connected between the four inclined plates 33 and the four fixed plates 31. A number of breaking forks 35 matching the slide grooves 29 are fixedly connected to the tops of the four inclined plates 33.

[0021] In this embodiment, when the second motor 13 in the bellows 8 is started and the rotating shaft 14 rotates, the rotating shaft 14 drives the first bevel gear 18 to rotate through the first synchronous belt 19, and the first bevel gear 18 is meshed with the second bevel gear 20, so that the power is transmitted to the second bevel gear 20. The second bevel gear 20 drives the first gear 21 fixedly connected to the first reciprocating screw 26 in the transmission box 10 to rotate through the second synchronous belt 24, thereby causing the first reciprocating screw 26 to start reciprocating motion; at the same time, the rotation of the second bevel gear 20 drives the second gear 23 fixedly connected to the synchronous shaft 22 in the transmission box 10 to rotate through the third synchronous belt 25, thereby causing the second reciprocating screw 27 adjacent to the first reciprocating screw 26 to also reciprocate.

[0022] Furthermore, the two first reciprocating screws 26 and the two second reciprocating screws 27 rotate back and forth in opposite directions, and the slider 30 threadedly sleeved on them will move back and forth in opposite directions along the screw. The fixed plate 31 fixedly connected to the top of the slider 30, the first slide bar 32 slidably connected to the fixed plate 31, the inclined plate 33 connected to the fixed plate 31 through the first spring 34, and the scattering fork 35 fixedly connected to the top of the inclined plate 33 will move synchronously. During the movement, the scattering fork 35 will impact and comb the mixed and entangled straw bales located below in different directions and strengths, and under the guidance and limiting action of the two scattering plates 28 and their slide grooves 29, the straw bales are repeatedly scattered, so that the straw is gradually dispersed, and the mixed and entangled straw bales can be fully scattered and dispersed, so that the straw can be more evenly distributed on the conveyor belt, which is convenient for subsequent transportation and processing, effectively avoiding the blockage problem caused by straw entanglement, achieving the beneficial effect of good scattering effect, and improving the working efficiency of the entire conveying device.

[0023] Embodiment three: Reference Figure 5 and Figure 8Compared with the first and second embodiments, the buffer assembly in this embodiment includes a cross beam 36 fixedly connected to the inside of the scattering box 2, four second sliding rods 37 are slidably connected to the cross beam 36, a vibration plate 38 is fixedly connected to the top of the four second sliding rods 37, four second springs 39 are fixedly connected between the vibration plate 38 and the cross beam 36, a bottom plate 40 is fixedly connected to the bottom of the four second sliding rods 37 and located inside the cross beam 36, a synchronization rod 41 slidably connected to the scattering box 2 is fixedly connected to the side of the bottom plate 40 close to the second fixed box 11, the synchronization rod 41 extends to the inside of the second fixed box 11, a rotating ring 42 is rotatably connected to the side of the second fixed box 11 close to the synchronization rod 41, the rotating ring 42 is connected to the rotating shaft 14 through a fourth synchronous belt 43, and four pressing plates 44 are fixedly connected to the rotating ring 42.

[0024] A feed port 3 is fixedly connected to the top of the scattering box 2, two support frames 4 are fixedly connected to both sides of the fixed base 1, a discharge port 5 is provided at the bottom of the fixed base 1, a conveyor belt 6 is arranged between the four support frames 4, a first motor 7 is fixedly connected to one side of a support frame 4, and a driving end of the first motor 7 is fixedly connected to a transmission shaft of the conveyor belt 6.

[0025] In addition, a buffer plate 45 is fixedly connected to the inside of the scattering box 2, and a plurality of through holes are provided on the buffer plate 45 and the vibration plate 38 for facilitating the passage of unwound straw.

[0026] In this embodiment, when the second motor 13 in the bellows 8 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the rotating ring 42 rotatably connected to the side of the synchronization rod 41 inside the second fixed box 11 to rotate through the fourth synchronous belt 43, and the four pressure plates 44 fixedly connected to the rotating ring 42 will make a circular motion with the rotating ring 42. The pressure plate 44 will periodically apply pressure to the synchronization rod 41 during the rotation process. The synchronization rod 41 extends to the inside of the second fixed box 11 and is fixedly connected to a bottom plate 40 at its bottom. The bottom plate 40 is connected to four second sliding rods 37 fixedly connected to the cross beam 36. The top of the second sliding rod 37 is fixedly connected to the vibration plate 38. Therefore, the pressure of the pressure plate 44 will be transmitted to the vibration plate 38 through the synchronization rod 41, the bottom plate 40, and the second sliding rod 37, so that the vibration plate 38 vibrates up and down on the cross beam 36, and the four second springs 39 connected between the vibration plate 38 and the cross beam 36 will expand and contract accordingly according to the vibration conditions.

[0027] At the same time, when the straw enters the breaking box 2 from the feed port 3 and falls on the vibration plate 38, on the one hand, the vibration of the vibration plate 38 can make the straw continuously jump and roll on its surface. In this process, the dust will gradually fall through the through holes on the vibration plate 38, waiting to be further collected by the dust collecting assembly; on the other hand, the vibration plate 38, under the action of the second spring 39, can buffer the impact force generated when the straw falls, thereby reducing the impact on the internal structure of the device.

[0028] Furthermore, the above operation not only achieves effective buffering of the straw entering the breaking box 2, reduces the impact of the straw on the device, and extends the service life of the device, but also can screen out dust through vibration, further improves the separation effect of straw and dust, optimizes the quality of straw, and achieves the beneficial effect of buffering and screening functions.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
