Description

Technical Field

[0001] This invention relates to the field of straw processing technology, specifically a straw shredder. Background Technology

[0002] Existing chaff cutters and integrated shredders differ in their processing methods. Choppers primarily use moving and fixed blades to cut crops into segments of varying lengths, but they lack the shredding effect and require frequent blade sharpening. Integrated shredders, on the other hand, mainly use a combination of hammers and blades for shredding. However, the shredding time in the shredding chamber is short, resulting in poor shredding. When the crop is wet, the shredded straw is relatively long, and the stems and nodes are not properly crushed. If the crop is dry, the shredded straw produces a lot of debris and dust, making them inefficient. Summary of the Invention

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0057] like Figure 1 As shown, a shredder includes a feeding mechanism 1, a first shredding chamber 2, a second shredding chamber 3, an air chamber 4, several telescopic components 5, and a mounting frame 6. The feeding mechanism 1 is rotatably mounted on the first shredding chamber 2. Both the first shredding chamber 2 and the second shredding chamber 3 are mounted on the mounting frame 6. The air chamber 4 is mounted on the discharge port side of the second shredding chamber 3. The telescopic components 5 are rotatably mounted on both sides of the first shredding chamber 2, and the output shaft of the telescopic components 5 is rotatably connected to the feeding mechanism 1. The processing sequence of straw is as follows: the straw enters through the feeding mechanism 1, receiving, transmitting, and initially processing the straw to be processed; it then enters the shredding chambers, where it is crushed and shredded by the first shredding chamber 2 and the second shredding chamber 3; finally, it is conveyed out from the air chamber 4.

[0058] like Figure 2As shown, the feeding mechanism 1 includes a transmission mechanism 11, a feeding mechanism housing 12, a sliding assembly 13, a first pressing roller 14, a second pressing roller 15, a third pressing roller 16, a material support roller 17, a plurality of first elastic elements 18, and a plurality of second elastic elements 19. The transmission mechanism 11 is mounted on the feeding mechanism housing 12 and is used to transport straw. The sliding assembly 13 is slidably disposed on the feeding mechanism housing 12. The first pressing roller 14 and the second pressing roller 15 both rotate on the sliding assembly 13. The third pressing roller 16 is connected to the feeding mechanism housing. The body 12 is rotatably connected, the third straw pressing roller 16 is below the first straw pressing roller 14, and the material support roller 17 is rotatably set at the end of the transmission mechanism 11 to facilitate the conveying of straw. The first elastic element 18 is set at both ends of the feeding mechanism housing 12, and the second elastic element 19 is distributed at both ends of the feeding mechanism housing 12. One end of the first elastic element 18 is connected to the sliding component 13, and the other end is connected to the feeding mechanism housing 12. One end of the second elastic element 19 is connected to the sliding component 13, and the other end is connected to the feeding mechanism housing 12. The first pressing roller 14 and the second pressing roller 15 are driven by a sprocket, and the third pressing roller 16 is driven by a sprocket to the transmission mechanism 11 (the transmission mechanism 11 can also be a separate drive). The straw is conveyed from the transmission mechanism 11, combed by the rotation of the second pressing roller 15, and then combed between the first pressing roller 14 and the third pressing roller 16. Under the tension of the first elastic element 18 and the second elastic element 19, the first pressing roller 14 and the second pressing roller 15 flatten the crop straw, initially compressing the thicker stems and the hard nodes on the surface of the straw, and performing preliminary treatment.

[0059] like Figure 2 , Figure 3 , Figure 5 As shown, the transmission mechanism 11 includes a fixed frame 111, a chain plate 112, a tensioning mechanism 113, a first transmission roller 114, and a second transmission roller 115. A material support roller 17 is rotatably mounted at one end of the fixed frame 111. The fixed frame 111 is mounted on the feeding mechanism housing 12. A sprocket mounted on the first transmission roller 114 and a sprocket rotatably mounted on the second transmission roller 115 are driven by the chain plate 112. The first transmission roller 114 is rotatably connected to the feeding mechanism housing 12, and the second transmission roller 115 is mounted on the fixed frame 111. The upper sliding mechanism 113 is fitted onto the end of the second transmission roller 115 (both ends of the second transmission roller 115 are equipped with the tensioning mechanism 113). The third pressing roller 16 and the first transmission roller 114 are driven by a sprocket. The screw on the tensioning mechanism 113 passes through the fixing frame 111. The tensioning mechanism 113 locks and positions the second transmission roller 115 on the fixing frame 111 through the screw and nut. When the chain plate 112 is loosened, rotating the nut pulls the screw and the second transmission roller 115 to the right (relative to the right). Figure 2 (in the middle position), thereby increasing the distance between the first transmission roller 114 and the second transmission roller 115, and tightening the chain plate 112.

[0060] like Figure 2 , Figure 4 As shown, the feeding mechanism housing 12 includes a housing body 121. The output shaft of the telescopic component 5 is rotatably connected to the housing body 121. A sliding groove 122 is provided on the housing body 121. A special-shaped groove 123 is opened on the housing body 121, and the special-shaped groove 123 communicates with the sliding groove 122. The sliding component 13 slides in the sliding groove 122 (sliding vertically). The fixed frame 111 is installed on the housing body 121. The third pressing roller 16 and the first transmission roller 114 are both rotatably connected to the housing body 121. A discharge port is provided on the side of the housing body 121 away from the transmission mechanism 11. A safety guard plate 124 is provided at the connection between the housing body 121 and the fixed frame 111. The safety guard plate 124 is rotatably connected to the housing body 121, which is convenient to open and clean when the grass is choked. The safety guard plate 124 is fixed to the fixed frame 111 by bolts. During operation, it prevents the operator's body from accidentally entering the feeding mechanism 1 and protects their personal safety. When opening, the bolts can be removed. A support shaft 125 is provided on the shell body 121. The support shaft 125 is used to rotatably connect the feeding mechanism 1 and the first kneading chamber 2, so as to facilitate the rotation between the two.

[0061] like Figure 2 , Figure 4 As shown, the sliding assembly 13 includes a sliding frame 131 and two connecting arms 132. The sliding frame 131 is rotatably connected to both ends of the connecting arms 132. The sliding frame 131 slides in the sliding groove 122 to limit the movement trajectory of the sliding frame 131. The first grass pressing roller 14 and the second grass pressing roller 15 are rotatably connected between the two connecting arms 132. The first grass pressing roller 14 is rotatably connected to the sliding frame 131. The first grass pressing roller 14 passes through the sliding frame 131 and is located at one end of the connecting arm 132. The second grass pressing roller 15 is located at the other end of the connecting arm 132 and is located in the irregular groove 123. One end of the first elastic element 18 is connected to the shell body 121, and the other end of the first elastic element 18 is connected to the end of the connecting arm 132 (the end where the first pressing roller 14 is provided). One end of the second elastic element 19 is connected to the shell body 121, and the other end is connected to the end of the connecting arm 132 (the end where the second pressing roller 15 is provided). The crop straw is flattened by the pulling force of the first elastic element 18 and the second elastic element 19, and the thicker stems and hard nodes on the surface of the straw are initially squeezed for preliminary treatment.

[0062] like Figure 5 , Figure 6 As shown, the first pressing roller 14, the second pressing roller 15, and the third pressing roller 16 have the same structure. Each of the three rollers has an inclined toothed plate 141 arranged in a ring. Figure 5For reference, during operation, the teeth on the toothed plate 141 of the first pressing roller 14 rotate counterclockwise, the teeth on the toothed plate 141 of the second pressing roller 15 rotate counterclockwise, and the teeth on the toothed plate 141 of the third pressing roller 16 rotate clockwise. The first pressing roller 14 and the third pressing roller 16 are connected to the drive source, ensuring that the first pressing roller 14 and the third pressing roller 16 rotate in opposite directions. This clamping operation serves as a material conveying function. Furthermore, the material can be unloaded when the material is stuck by controlling the rotation direction of the first pressing roller 14 and the third pressing roller 16.

[0063] like Figure 7 , Figure 8 As shown, the first kneading chamber 2 includes a first kneading chamber shell 21, an auger shaft 22, and a kneading assembly. The auger shaft 22 is provided with at least two bearing seat assemblies for supporting the auger shaft 22. The auger shaft 22 rotates on the bearing seat assemblies, which are mounted on the first kneading chamber shell 21. The first kneading chamber shell 21 is rotatably connected to the shell body 121 via a support shaft 125. The telescopic member 5 is rotatably connected to the first kneading chamber shell 21. The auger shaft 22 is provided with a pulley for transmission. The kneading assembly is provided on the auger shaft 22 for kneading crop straw. A linear array of first fixed blades 26 is provided at the feed inlet of the first kneading chamber shell 21 for cutting and crushing the crop straw fed by the transmission mechanism 11. During operation, the feed inlet of the first kneading chamber shell 21 is connected to the discharge outlet of the shell body 121 to ensure the normal and orderly transmission of straw.

[0064] It should be noted that, as Figure 8 As shown, the bearing housing assembly includes a bearing housing 23, a bearing 231, several oil sealing caps 24, and several oil seals 241. The bearing housing 23 is installed on the housing 21 of the first kneading chamber. The bearing housing 23 is rotatably connected to the auger shaft 22 through the bearing 231. Oil sealing caps 24 are provided on both sides of the bearing housing 23. The oil sealing caps 24 are connected to the auger shaft 22 through the oil seals 241. The oil seals 241 seal the bearing 231 to prevent dust and impurities from entering the inner cavity of the bearing 231, thereby improving the performance and lifespan of the bearing 231. An oil cup 25 is provided on the bearing assembly and is connected to the bearing 231 for oiling the bearing 231.

[0065] One embodiment, such as Figure 8 , Figure 9As shown, to improve the crushing and kneading effect of crop straw in the first kneading chamber 2, the kneading assembly and the inner cavity of the first kneading chamber shell 21 are designed. Multiple sets of second fixed blades 27 (which can be ring-shaped, semi-ring-shaped, or ring-shaped at a certain angle, or set at a set interval along the material conveying direction, and can be increased or decreased according to the crushing effect during operation) are arranged on the inner wall of the first kneading chamber shell 21. Each set of second fixed blades 27 is equipped with several blade heads, and the blade heads are arranged in a linear array along the axial direction of the auger shaft 22; and there is a certain distance between the blade heads of the second fixed blades 27. The kneading assembly on the auger shaft 22 includes multiple sets of arrayed hammer claws 221 and support blocks 222. The hammer claws 221 are rotatably mounted on the support blocks 222 via connecting pins. The support blocks 222 are fixed on the auger shaft 22. Adjacent arrays of hammer claws 221 are alternately distributed. Only one hammer claw 221 exists on the outer wall of the auger shaft 22 along its axial direction. The hammer claw 221 is projected along the axial direction (as shown in the diagram). Figure 9 (Viewpoint), the projections of each hammer claw 221 do not overlap, and the hammer claw 221 bends in the direction of clockwise rotation (to... Figure 9 (Perspective) to facilitate gripping while accelerating feeding and kneading efficiency. After the hammer claw 221 and support block 222 are assembled on the auger shaft 22, dynamic balance adjustment is performed, with an imbalance of ≤6 grams. When the hammer claw 221 rotates normally, its claw tip passes through the intervals of the arrayed second fixed blades 27, forming staggered cutting. While kneading, it works in conjunction with the second fixed blades 27 to effectively cut and crush crop straw with a certain degree of toughness or hardness.

[0066] One embodiment, such as Figure 10 , Figure 11 As shown, to improve the crushing and kneading effect of crop straw in the first kneading chamber 2, the kneading assembly is designed. The kneading assembly on the auger shaft 22 includes several blade holders 223 and several hook blades 224. The hook blades 224 are installed on the blade holders 223 and can be fixed to the blade holders 223 by bolts and flange nuts for easy maintenance and replacement. They can also be fixed by welding. The bending direction of the hook blades 224 is towards the rotation direction during normal cutting. Figure 11 From a perspective of rotation, the auger shaft 22 rotates clockwise for normal cutting, and the blade head of the hook-type blade 224 also bends clockwise, facilitating the hooking, crushing, and filament-drawing of straw from the feed inlet. The hook-type blade 224 effectively reduces the amount of debris produced by dry crops, thereby reducing dust. The blade handle 223 is mounted and fixed on the surface of the auger shaft 22, and the blade handles 223 are arranged in an array on the auger shaft 22. After the blade handles 223 and hook-type blades 224 are installed on the auger shaft 22, they need to be dynamically balanced as a whole, with an imbalance of ≤4 grams. The rotation of the hook-type blade 224, in conjunction with the first fixed blade 26, produces cutting, tearing, lifting, and slicing effects, while also having a throwing function.

[0067] One embodiment, such as Figure 12 , Figure 13 As shown, to improve the crushing and kneading effect of crop straw in the first kneading chamber 2, the kneading assembly is designed. The kneading assembly on the auger shaft 22 includes several sets of roller cutters 225. Each set of roller cutters 225 is arranged in a circular array, with adjacent sets of roller cutters 225 alternating. The roller cutters 225 are inclined. Several positioning grooves are provided on the auger shaft 22, and the roller cutters 225 are fixed in the positioning grooves by bolts. Figure 13 From a normal cutting perspective, during normal operation, the auger shaft 22 rotates clockwise, and the cutting edge of the roller cutter 225 is positioned clockwise. After the roller cutter 225 is installed, dynamic balancing is required, and the imbalance should be ≤6 grams. The rotational speed of the auger shaft 22 does not exceed 1200 r / min. The rotating roller cutter 225 cuts the straw and also has a throwing function, making it effective for processing green corn stalks.

[0068] like Figure 7 As shown, the second kneading chamber 3 includes a second kneading chamber shell 31 (tubular), a conveying chamber 32, a rotating shaft 33, and several fixed blade assemblies 34. The conveying chamber 32 is installed on the discharge port side of the first kneading chamber shell 21 and is fixed on the mounting bracket 6. The inlet of the conveying chamber 32 is connected to the discharge port of the first kneading chamber shell 21. The second kneading chamber shell 31 is installed at the discharge port of the conveying chamber 32, and its inlet is connected to the discharge port of the conveying chamber 32. A drain hole 35 is provided on the conveying chamber 32 for draining water. The straw contains mixed slag. Fixed blade assemblies 34 are arranged in a ring array on the second kneading chamber shell 31. Each fixed blade assembly 34 includes several third fixed blades 341. The blades of the third fixed blades 341 pass through the second kneading chamber shell 31 and are simultaneously limited, forming a linear array. The linear array of third fixed blades 341 is traversed by a connecting shaft. The connecting shaft is slidably mounted on a bracket of the second kneading chamber shell 31 and is fixed by limiting pins. A rotating shaft 33 is rotatably mounted on the conveying chamber 32 via a bearing seat assembly. Figure 14 As shown, a spiral blade 36 is provided on the rotating shaft 33. The spiral blade 36 is inside the conveying chamber 32, which feeds the straw in the conveying chamber 32 into the second rubbing chamber shell 31. Several moving blade seats 37 and several moving blades 38 are provided on the rotating shaft 33. The moving blade seats 37 are arranged in an array on the rotating shaft 33 and fixed. Both the moving blade seats 37 and the moving blades 38 are inside the second rubbing chamber shell 31. Each moving blade seat 37 is provided with at least two moving blades 38. There is a gap between the two moving blades 38. When the moving blades 38 rotate, the blade head of the third fixed blade 341 passes through the gap of the moving blades 38 (that is, there is a misalignment and overlap between the moving blades 38 and the third fixed blade 341 during operation), forming an interlaced cutting, which can complete the function of cutting the crop. When the crop is wet, when the third fixed blade 341 and the moving blades 38 work together to cut each other, the longer rubbing straw can be cut into shorter straw, which is easier for livestock to chew and digest.

[0069] like Figure 7 , Figure 15 As shown, the air chamber 4 includes an air chamber housing 41 and several impellers 42. The rotating shaft 33 is rotatably mounted on the air chamber housing 41 through a bearing housing assembly. The impellers 42 are inclined and arrayed on the rotating shaft 33. The impellers 42 are inside the air chamber housing 41. The air chamber housing 41 is installed on the discharge port side of the second kneading chamber housing 31. The inlet of the air chamber housing 41 is connected to the discharge port of the second kneading chamber housing 31. After the spiral blades 36, the moving knife seat 37, the moving knife 38 and the impellers 42 are mounted on the rotating shaft 33, dynamic balancing is performed. The imbalance is ≤6 grams. The impeller 42 rotates, and the straw inside is thrown out from the discharge port of the wind chamber shell 41. The impeller 42 rotates at high speed and transports the processed straw. The straw and the inside of the wind chamber shell 41 generate a large friction force. Removable wear-resistant plates can be installed at the friction points of the wind chamber shell 41 to increase its service life and facilitate replacement. Removable wear-resistant plates can also be installed on the inner walls of the second kneading chamber shell 31, the conveying chamber 32 and the first kneading chamber shell 21 that are in contact with the straw to increase their service life and facilitate replacement.

[0070] like Figure 1 As shown, the auger shaft 22 and the rotating shaft 33 are driven by pulleys. The shredder also includes a drive unit to provide power, which is also driven by pulleys to the auger shaft 22. Figure 4 As shown, both the first pressing roller 14 and the third pressing roller 16 are equipped with driving components, and the first pressing roller 14 and the third pressing roller 16 rotate in opposite directions.

[0071] Working principle:

[0072] The drive source drives the rotating shaft 33 to rotate via a belt pulley drive. The rotating shaft 33 drives the auger shaft 22 to rotate via a belt pulley drive. The drive source drives the first pressing roller 14 and the third pressing roller 16 to rotate. The first pressing roller 14 and the third pressing roller 16 rotate in opposite directions. The third pressing roller 16 drives the first transmission roller 114 to rotate via a sprocket drive, which in turn drives the transmission mechanism 11 to run. The first pressing roller 14 drives the second pressing roller 15 to rotate via a sprocket drive. The straw is put into the transmission mechanism 11 and conveyed into the first kneading chamber 2 via the chain plate 112. The straw is pre-treated by the action of the first fixed blade 26, the kneading component on the auger shaft 22 and the second fixed blade 27. The pre-treated straw enters the second kneading chamber 3. The straw is conveyed into the shell 31 of the second kneading chamber by the rotation of the spiral blade 36. After being cut by the moving blade 38 and the third fixed blade 341, the straw enters the air chamber 4. The processed straw is sent out by the rotation of the impeller 42 in the air chamber 4.
