Description

Technical Field

[0001] The invention relates to the technical field of agricultural crop straw crushing, and in particular to environmentally friendly processing equipment for agricultural solid waste. Background Art

[0002] Solid waste from the planting industry is the main component of agricultural solid waste, including various crop straws, residues, husks, rice husks, etc. Among them, straw, as a renewable resource, can be used for many purposes after crushing, such as returning to the fields, making it into feed, and turning it into energy, thus avoiding the waste of resources. Crushing crop straw can effectively reduce straw burning, making an outstanding contribution to environmental protection.

[0003] Announcement No.: CN218042583U discloses a straw crusher. By starting the exhaust fan, the dust generated during the crushing is sucked into the air inlet of the exhaust fan, and then sprayed out from the dust removal pipe through the air outlet of the exhaust fan. At this time, the water pump is started, and the water pump pumps the water flow in the water tank into the nozzle, and sprays it out through the nozzle, thereby reducing the dust sprayed out from the dust cover and making it difficult for the dust to float away. This device makes the dust after the straw is crushed difficult to be inhaled by the human body, which is not easy to cause harm to the human body and is not easy to pollute the environment.

[0004] Announcement No.: CN109263129A discloses a straw briquetting machine for biomass power generation. A motor drives a plurality of combined crushing knives to rotate at high speed, and the straw is cut and crushed in the crushing barrel to facilitate the full combustion of the straw during power generation. The crushed straw flows into a forming frame and is squeezed into blocks by a cylinder-driven pressing plate, which is convenient for storage and transportation, thereby improving the utilization rate of the straw and saving energy.

[0005] In the related art, when crop straw is used as animal feed or for biomass power generation, it is necessary to crush the straw. Crop straw is roughly divided into two categories, one is high in fiber content and high in lignification, such as corn straw, and the other is relatively thin and soft with low fiber content, such as wheat straw. When the existing agricultural crop straw is crushed, it is not convenient to quickly crush the two types of straw efficiently. When the two types of straw are crushed at the same time, because one of the straws has a high degree of lignification, the particle sizes of the two types of straws after being crushed at the same time are often different.

[0006] Therefore, it is necessary to provide an environmentally friendly treatment device for agricultural solid waste to solve the above technical problems. Summary of the invention

The rotation of the first synchronous wheel 33 drives the second synchronous wheel 34 to rotate through the synchronous belt 35. The rotation of the second synchronous wheel 34 drives the cutting roller 31 to rotate. The cutting roller 31 drives the cutting knife group 32 to cut the straw with a high degree of lignification; Furthermore, when the cutting roller 31 rotates, it will simultaneously drive the fourth pulley 39 to rotate, and the fourth pulley 39 rotates through the second belt 310 to drive the third pulley 38 to rotate, and the third pulley 38 rotates to drive the squeezing roller 36 on the left to rotate, and the squeezing roller 36 on the right to rotate with the cooperation of the rotating gear 37, and the rotation of the two squeezing rollers 36 squeezes and crushes the straw with a high degree of lignification, destroying the fiber of the straw, so as to facilitate subsequent cutting and crushing; The feeding mechanism 4 comprises two mounting frames 41 fixedly mounted on the right side surface of the crushing drum 21, two conveying rollers 42 are rotatably connected to the opposite sides of the two mounting frames 41, and conveying belts 43 are sleeved on the surfaces of the two conveying rollers 42.

The conveying belt 43 moves so that the straw with a low degree of lignification can be transported, and the straw with a low degree of lignification can be transported into the crushing cylinder 21 through the first feed port opened on the right side of the crushing cylinder 21.

[0025] The inner sides of the crushing barrel 21 correspond to the crushing knife group 23 and the cutting knife group 32 respectively, and are provided with a crushing cavity and a cutting cavity.

[0026] A filter cover 5 is fixedly provided on the inner wall of the crushing cylinder 21 and at the bottom of the crushing knife group 23. The filter cover 5 can be replaced according to the crushing requirements. A through groove used in conjunction with the crushing cylinder 21 is provided on the inner side of the base 1 to facilitate the falling of materials.

[0027] Preferably, in this case, when crushing the straw, there are three schemes that can be implemented according to the use requirements: The first method is that when only straw with a low degree of lignification needs to be crushed, the synchronous belt 35 is removed, and then the drive motor 24 and the feeding motor 44 are started at the same time. The first pulley 25 is driven to rotate by the rotation of the drive motor 24, and the first pulley 25 drives the second pulley 26 to rotate through the first belt 27. The second pulley 26 drives the crushing roller 22 and the crushing knife group 23 to rotate through the rotation of the second pulley 26. The straw with a low degree of lignification is transported to the crushing cylinder 21 by the conveyor belt 43 through the rotation of the feeding motor 44, and then crushed by the crushing knife group 23; The second method is to start the driving motor 24 when only the straw with a high degree of lignification needs to be crushed. The driving motor 24 is rotated to drive the first pulley 25 to rotate. The first pulley 25 drives the second pulley 26 to rotate through the first belt 27. The second pulley 26 drives the crushing roller 22 and the crushing knife group 23 to rotate. When the crushing roller 22 rotates, it drives the first synchronous wheel 33 to rotate. The rotation of the first synchronous wheel 33 drives the second synchronous wheel 34 to rotate through the synchronous belt 35. 4 rotates, thereby driving the cutting roller 31 and the cutting knife group 32 to rotate. When the cutting roller 31 rotates, it will also drive the fourth pulley 39 to rotate. The fourth pulley 39 rotates through the second belt 310 to drive the third pulley 38 to rotate. The third pulley 38 rotates in cooperation with the two rotating gears 37 to drive the two squeezing rollers 36 to rotate. After the straw with a high degree of lignification is put into the second feeding port, the straw can be squeezed, cut and crushed in turn, thereby improving the crushing efficiency of the straw with a high degree of lignification; The third method: when it is necessary to crush straws with a high degree of lignification and straws with a low degree of lignification at the same time, start the drive motor 24 and the feeding motor 44, and then feed the two types of straws through the first feed port and the second feed port respectively, use the squeezing roller 36 to squeeze the straws with a high degree of lignification, use the cutting knife group 32 to cut them, and then use the crushing knife group 23 to crush the two types of straws at the same time, thereby improving the straw crushing efficiency and the uniformity of the particles after the two types of straws are crushed.

[0028] In this embodiment, unlike the existing agricultural crop straw crushing device, in this case, when working, straw with a high degree of lignification is fed from the second feed port, and straw with a low degree of lignification is fed from the first feed port. The straw with a high degree of lignification is squeezed by the rotation of the squeezing roller 36 to destroy the straw fiber, and then the squeezed straw is cut into small sections by the cutting knife group 32. The crushing roller 22 drives the crushing knife group 23 to crush the straw with a high degree of lignification and the straw with a low degree of lignification at the same time. While improving the straw crushing efficiency, the uniformity of the crushed particles of the two types of straws with different degrees of lignification can also be improved.

The hydraulic cylinder 65 will reciprocate and extend, thereby driving the extrusion template 66 to extrude the crushed materials and squeeze the crushed straw into blocks; Furthermore, when the hydraulic cylinder 65 drives the extrusion template 66 to reciprocate and extrude the falling material, the extrusion template 66 reaches the final position on the left side, which is located at the left side of the material discharge chute opened inside the material guide box 61 .

[0030] The material guide box 61 is connected to the extrusion box 63, and the two adjustment plates 68 are used in conjunction with the two limit frames 69 respectively; Preferably, the two adjustment plates 68 are rotated toward each other, thereby canceling the limit on the rotating plate 67, and then the rotating plate 67 can be opened. A through groove is provided on the inner side of the top of the extrusion box 63 for use with the extrusion template 66, which can provide the extrusion template 66 to slide left and right. The cross-section of the guide plate 62 is arc-shaped, which is convenient for unloading the crushed straw.

The movement of the two pulling frames 75 drives the two rotating brackets 74 to rotate counterclockwise in the rotating seat 73 under the action of the pull rod 76. The rotation of the two rotating brackets 74 drives the rotating plate 67 to rotate. Under the continuous extension of the hydraulic cylinder 65, the extruded block material is gradually pushed out of the extrusion box 63, and the block material finally slides to the ground through the rotating plate 67, thereby completing the briquetting and discharging of the crushed straw; Furthermore, after the discharging of the crushed straw briquette is completed, the hydraulic cylinder 65 is controlled to retract, and the retraction of the hydraulic cylinder 65 drives the extrusion template 66 and the two sealing plates 710 to move to the right. The movement of the bottom sealing plate 710 drives the driving gear 78 to rotate in the opposite direction under the action of the first gear plate 711, and the driving gear 78 drives the passive gear 79 to rotate in the opposite direction through the rotating rod 77, and the rotation of the passive gear 79 drives the second gear plate 712 to move to the left, and the second gear plate 712 drives the moving plate 72 and the two pulling frames 75 to move to the left. The two pulling frames 75 drive the rotating bracket 74 to rotate clockwise under the action of the pull rod 76, and the rotating plate 67 is driven to rotate through the rotation of the rotating bracket 74, and the rotating plate 67 is reset. After resetting, the rotating plate 67 can be re-limited by the adjusting plate 68.

[0032] The inner sides of the rotating seat 73 and the rotating bracket 74 are provided with sliding grooves for use with the pull rod 76, which can allow the pull rod 76 to move left and right. The top and bottom of the baffle 64 are provided with grooves for use with the sealing plate 710, which can allow the sealing plate 710 to slide left and right. The sealing plate 710 on the top is used to block the discharge port of the material guide box 61 when the extrusion template 66 moves to the left.

[0033] In this embodiment, the reciprocating extension of the hydraulic cylinder 65 drives the extrusion template 66 to extrude the crushed material and squeeze the crushed material into blocks. When the hydraulic cylinder 65 continues to extend, it drives the extrusion template 66 and the two sealing plates 710 to move to the left, and the block material is pushed to the left by the extrusion template 66. When the bottom sealing plate 710 moves, it drives the first gear plate 711 to move synchronously, thereby causing the driving gear 78 to rotate, and under the action of the rotating rod 77, it drives the driven gear 79 to rotate, and the driven gear 79 drives the second gear plate 712 and the moving plate 72 and the pulling frame 75 move to the right, and under the action of the pull rod 76, the two rotating brackets 74 are driven to rotate counterclockwise in the rotating seat 73, and the rotating plate 67 is driven to rotate through the rotation of the two rotating brackets 74. Under the continuous extension of the hydraulic cylinder 65, the material extruded into blocks is gradually pushed out of the extrusion box 63, which is very convenient for extruding the crushed straw into blocks and discharging the material at one time, and is convenient for the subsequent transportation of the crushed straw.
