Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of straw processing, in particular to a feeding device based on crop straw processing. BACKGROUND

[0002] Crop straw is an important organic waste generated in the process of agricultural production, which refers to the stems, leaves, ear axes and other aboveground parts of grain crops, economic crops and forage crops after harvesting. It has dual attributes of "resource" and "environmental burden". Scientific and reasonable treatment and utilization of straw is of great significance to sustainable development of agriculture and ecological environment protection.

[0003] When the straw is crushed, there may be large particles of soil and other impurities in the accumulated straw, which can easily damage the crushing equipment and cause equipment failure. In addition, when the straw is crushed, it is usually crushed by continuously feeding the straw by hand. A large amount of feeding at one time can cause the crushing equipment to overload and shut down, affecting the crushing efficiency of the straw. Some crop straws are long, and the crushing equipment is difficult to completely accommodate. In addition, the pulling force of the crushing equipment on the straw during the crushing process is large, which has a certain risk.

[0022] 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.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a feeding device based on crop straw processing.

[0024] like Figures 1-9 As shown, a feeding device based on crop straw processing includes a frame 1, on which two rotating shafts 2 are mounted. Toothed rollers 3 are fixedly mounted on both sides of the two rotating shafts 2. A metal conveyor belt 4 is provided outside the two rotating shafts 2. The inner wall of the metal conveyor belt 4 has drive tooth grooves that match the toothed rollers 3. Multiple vibrating plates 5 are slidably mounted on the metal conveyor belt 4. A patterned roller 16 is fixed outside the rotating shaft 2 on the left side, matching the vibrating plate 5. A power motor 43 is mounted outside the frame 1. The drive shaft of the power motor 43 rotates through the frame 1 and is coaxially fixed to the rotating shafts 2. A shearing mechanism 6 for cutting straw is provided above the metal conveyor belt 4. A lifting mechanism for lifting the multiple vibrating plates 5 is provided inside the metal conveyor belt 4. Guide rollers 23 are mounted on the frame 1. It is clear that multiple actuating plates are installed on the outer side of the guide roller 23, and the multiple actuating plates are evenly distributed on the outer side of the guide roller 23. The guide roller 23 and the rotating shaft 2 are connected by a third transmission mechanism 40. Further, the third transmission mechanism 40 includes a third pulley 41 and a fourth pulley 42. The third pulley 41 is coaxially installed with the rotating shaft 2, and the fourth pulley 42 is coaxially installed with the guide roller 23. The third pulley 41 and the fourth pulley 42 are connected by a synchronous belt. A waste discharge trough 24 is provided below the guide roller 23. It is worth mentioning that the inner bottom of the waste discharge trough 24 is inclined. The frame 1 is provided with a notch that matches the opening of the waste discharge trough 24. The waste discharge trough 24 is fixed to the frame 1. A quantitative feeding mechanism for quantitatively feeding straw is provided on the side of the guide roller 23 away from the metal conveyor belt 4.

[0025] To avoid the danger of excessively long straw during the crushing process, a shearing mechanism 6 is provided. The shearing mechanism 6 includes a shearing box 7 mounted on the frame 1. A chainsaw 10 is installed inside the shearing box 7, and a U-shaped mounting plate 11 is installed outside the chainsaw 10. The U-shaped mounting plate 11 slides through the shearing box 7. A first crankshaft 8 is installed inside the shearing box 7. A deflection plate 9 is rotatably mounted on the protruding part of the first crankshaft 8. The lower end of the deflection plate 9 is rotatably mounted with the U-shaped mounting plate 11. One end of the first crankshaft 8 rotatably passes through the shearing box 7 and is connected to the rotating shaft 2 through a first transmission mechanism 12. It is worth mentioning that the first transmission mechanism 12 includes a first pulley 13 and a second pulley 14. The first pulley 13 is coaxially mounted with the rotating shaft 2, and the second pulley 14 is coaxially mounted with the first crankshaft 8. The first pulley 13 and the second pulley 14 are connected by a synchronous belt drive.

[0026] Through the above technical features: the power motor 43 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the first crankshaft 8 to rotate, the first crankshaft 8 drives the U-shaped mounting plate 11 to reciprocate up and down through the deflection plate 9, the U-shaped mounting plate 11 drives the chainsaw 10 to rise and fall, and the chainsaw 10 can intermittently cut the straw through the chainsaw 10, which has a high safety level when transporting the straw and when crushing it later.

[0027] To separate impurities such as soil clods from the straw, a lifting mechanism is provided. The lifting mechanism includes a vibrating box 15 installed inside the metal conveyor belt 4. The vibrating box 15 is fixedly installed with the frame 1. Two second crankshafts 17 are rotatably installed inside the vibrating box 15. One end of each of the two second crankshafts 17 rotatably passes through the vibrating box 15 and is connected to one of the rotating shafts 2 via a bevel gear set 22. It should be noted that the bevel gear set 22 includes a first bevel gear 20 and a second bevel gear 21 that mesh with each other. The first bevel gear 20 is coaxially installed with the rotating shaft 2, and the second bevel gear 21 is coaxially installed with the second crankshaft 17. Multiple lifting plates 19 are provided above the two second crankshafts 17. The multiple lifting plates 19 are slidably installed through the vibrating box 15. The lifting plates 19 correspond to the vibrating plates 5. Reciprocating plates 18 are rotatably installed on the protruding parts of the second crankshafts 17. The upper end of the reciprocating plates 18 is rotatably connected to the lifting plates 19.

[0028] Through the above technical features: the power motor 43 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the toothed roller 3 and the guide roller 23 to rotate, the toothed roller 3 drives the metal conveyor belt 4 and the vibrating plate 5 to drive the transmission. At the same time, the rotating shaft 2 drives the second crankshaft 17 to rotate, the second crankshaft 17 drives the lifting plate 19 to move up and down repeatedly through the reciprocating plate 18, the lifting plate 19 drives the vibrating plate 5 to move up and down repeatedly. During the conveying process, the vibrating plate 5 can frequently vibrate the straw, shaking off the soil clods and other impurities in the straw onto the metal conveyor belt 4. The metal conveyor belt 4 directly transports the impurities to the discharge trough 24 for discharge. The straw is transported to the return plate 25 through the guide roller 23, which can complete the separation of straw and impurities, and facilitate the subsequent crushing of straw.

[0029] It should be noted that the spacing between two adjacent vibrating plates 5 is approximately equal to the width of the lifting plate 19. When the vibrating plate 5 moves from the outside of the lifting plate 19 to the position of the lifting plate 19, the lifting plate 19 is at its lowest point. When the vibrating plate 5 moves to the edge of the lifting plate 19, the lifting plate 19 is also at its lowest point. The lifting and lowering of the lifting plate 19 completes one cycle. The lifting plate 19 can smoothly drive the vibrating plate 5 to rise and fall without the vibrating plate 5 colliding with the lifting plate 19.

[0030] To avoid feeding too much straw to the subsequent crushing equipment at once, a quantitative feeding mechanism is set up. This mechanism includes a molded plate 25 fixedly mounted on a frame 1. Two main shafts 28 are rotatably mounted inside the molded plate 25. Flip plates 26 are fixed to the outside of each main shaft 28, and both flip plates 26 are matched with the molded plate 25. A transmission cavity 27 is provided inside the molded plate 25. Both main shafts 28 rotatably pass through the molded plate 25 and extend into the transmission cavity 27. A transmission shaft 29 is rotatably mounted inside the transmission cavity 27. The transmission shaft 29 is connected to the two main shafts 28 via a drive mechanism 30. It should be noted that the drive mechanism 30 includes meshing worm gears 32 and worm wheels 33. The worm gears 32 are coaxially mounted with the transmission shafts 29, and the worm wheels 33 are coaxially mounted with the main shafts 28. It is important to note that the two worm gears 32... The spiral directions are opposite. A drive motor 31 is installed outside the molded plate 25. The drive shaft of the drive motor 31 rotates through the molded plate 25 and is coaxially installed with the transmission shaft 29. A pocket frame 34 is provided below the molded plate 25. A rotating shaft 35 is fixedly installed on the pocket frame 34. The rotating shaft 35 is rotatably installed with the frame 1. A rotating motor 36 is installed outside the frame 1. The drive shaft of the rotating motor 36 rotates through the frame 1 and is coaxially installed with the rotating shaft 35. The pocket frame 34 is rotatably installed with the frame 1. A buffer plate 38 is slidably installed inside the pocket frame 34. The buffer plate 38 is connected to the bottom of the pocket frame 34 by a return spring 39. A trigger 37 is installed inside the pocket frame 34. The trigger 37 corresponds to the buffer plate 38. It should be noted that a sensor is embedded in the flip plate 26 and the sensor is electrically connected to the drive motor 31.

[0031] Through the above technical features: the drive motor 31 drives the transmission shaft 29 to rotate, the transmission shaft 29 drives the two main shafts 28 to rotate relative to each other, and the main shafts 28 drive the flap 26 to rotate relative to each other. When the sensor senses that straw has accumulated on the flap 26, the drive motor 31 drives the flap 26 to open, so that the straw falls onto the buffer plate 38. Then the flap 26 closes. At this time, when the buffer plate 38 has accumulated a certain weight of straw, the straw will press down on the buffer plate 38 until the buffer plate 38 contacts the trigger 37. At this time, the rotating motor 36 drives the rotating shaft 35 to rotate, and the rotating shaft 35 drives the hopper 34 and the buffer plate 38 to rotate, so that the current weight of straw can be dumped and quantitatively fed to the crushing equipment for crushing, avoiding equipment shutdown due to overload crushing, and scientifically crushing straw.

[0032] Working principle: 1) Straw cutting: The power motor 43 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the first crankshaft 8 to rotate, the first crankshaft 8 drives the U-shaped mounting plate 11 to move up and down through the deflection plate 9, the U-shaped mounting plate 11 drives the chainsaw 10 to move up and down, and the chainsaw 10 can intermittently cut the straw. 2) Separation of straw impurities: The power motor 43 drives the rotating shaft 2 to rotate, which in turn drives the toothed roller 3 and the guide roller 23 to rotate. The toothed roller 3 drives the metal conveyor belt 4 and the vibrating plate 5 to drive the transmission. At the same time, the rotating shaft 2 drives the second crankshaft 17 to rotate. The second crankshaft 17 drives the lifting plate 19 to move up and down repeatedly through the reciprocating plate 18. The lifting plate 19 drives the vibrating plate 5 to move up and down repeatedly. During the conveying process, the vibrating plate 5 can frequently vibrate the straw, shaking off the soil clods and other impurities in the straw onto the metal conveyor belt 4. The metal conveyor belt 4 directly transports the impurities to the discharge trough 24 for discharge. The straw is then transported to the return plate 25 through the guide roller 23, thus completing the separation of straw and impurities. 3) Quantitative supply of straw: The drive motor 31 drives the transmission shaft 29 to rotate, which in turn drives the two main shafts 28 to rotate relative to each other. The main shafts 28 drive the flaps 26 to rotate relative to each other. When the sensor detects that straw has accumulated on the flaps 26, the drive motor 31 drives the flaps 26 to open, allowing the straw to fall onto the buffer plate 38. Then the flaps 26 close. When the buffer plate 38 has accumulated a certain weight of straw, the straw will press down on the buffer plate 38 until the buffer plate 38 contacts the trigger 37. At this time, the drive motor 36 drives the drive shaft 35 to rotate, which in turn drives the hopper 34 and the buffer plate 38 to rotate, thus dumping the current weight of straw and quantitatively supplying it to the crushing equipment for crushing.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
