[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-4 The utility model provides a technical solution: a straw shredding machine, comprising a shell 1, a connecting shell 2 connected to one side of the surface of the shell 1, a shredding mechanism 3 provided inside the shell 1, a feed inlet 4 provided on one side of the surface of the shell 1, a discharge port 5 provided on one side of the surface of the shell 1, a supporting leg 6 connected to one side of the surface of the shell 1, and a dust collecting mechanism 7 provided inside the connecting shell 2;
[0020] The dust collection mechanism 7 includes a porous partition 701, a connecting plate 702, a through hole 703, a filter 704 and a fan 705. One side of the surface of the outer shell 1 is connected to the porous partition 701, and the surface of the connecting shell 2 is hingedly connected to the connecting plate 702. One side of the surface of the connecting shell 2 is provided with a through hole 703. The filter 704 is embedded in the interior of the connecting shell 2, and the fan 705 is embedded in the interior of the connecting shell 2. When the silk pulverizer is working, the fan 705 is started first. The rotation of the fan 705 will cause the air inside the connecting shell 2 to flow. Due to the suction effect of the fan 705, a negative pressure is formed inside the connecting shell 2. Pressure zone, at this time, the air with dust in the outer shell 1 will enter the connecting shell 2 through the porous partition 701. When the air entering the connecting shell 2 passes through the filter 704, the dust and other impurities will be intercepted by the filter 704 and fall to the bottom of the connecting shell 2, and the filtered air will be discharged to the outside through the through hole 703 on the surface of the connecting shell 2, thereby achieving the purpose of dust collection. When the dust inside the connecting shell 2 needs to be cleaned out, the connecting plate 702 can be opened, and the dust can be cleaned at this time, which effectively reduces the dust generated during the straw kneading and crushing process, avoids the spread of dust in the equipment and the surrounding environment, and prevents workers from inhaling it.
[0021] Furthermore, the fan 705 is embedded in the inside of the through hole 703, and two groups of fans 705 are provided. Through the setting of the fan 705, when in use, the fan 705 generates suction by rotating during operation, so that the air pressure inside the connecting shell 2 is lower than the air pressure inside the outer shell 1, thereby prompting the dust-laden air in the outer shell 1 to be sucked into the connecting shell 2 through the porous partition 701.
[0022] Furthermore, the filter 704 is embedded in the inside of the through hole 703, and the filter 704 is in contact with the inner wall of the connecting shell 2. Through the setting of the filter 704, when in use, the filter 704 can effectively intercept dust and other impurities and only allow clean air to pass through the through hole 703, thereby preventing dust from spreading to the outside of the device.
[0023] Furthermore, the kneading and crushing mechanism 3 includes a motor 301, a toothed plate 302, an upper roller 303, a lower roller 304, a connecting rod 305, a first pulley 306, a second pulley 307, a turntable 308, a transmission belt 309, a fixing rod 310 and a hammer 311. The motor 301 is installed on one side of the surface of the shell 1, the toothed plate 302 is connected to the inside of the shell 1, the upper roller 303 is connected to the inside of the shell 1, the lower roller 304 is connected to the inside of the shell 1, and one end of the motor 301 is connected to the connecting rod 311. The upper roller 303 is connected to the first pulley 306 at one end of the connecting rod 305, the second pulley 307 at one end of the connecting rod 305, the turntable 308 at one end of the connecting rod 305, the second pulley 307 is provided with a transmission belt 309, the surface of the turntable 308 is connected to the fixed rod 310 at one side, the hammer 311 is connected to the fixed rod 310 at one end of the fixing rod 310. The arrangement of a pulley 306, a second pulley 307, a turntable 308, a transmission belt 309, a fixed rod 310 and a hammer 311, when in use, when kneading and crushing straw, first start the motor 301, then one end of the motor 301 drives the connecting rod 305 to rotate, then the connecting rod 305 drives the turntable 308 and the second pulley 307 to rotate, then the turntable 308 drives the hammer 311 to rotate through the fixed rod 310, and the hammer 311 then continuously rotates around the turntable 308 and hits Toothed plate 302, at the same time, the second pulley 307 drives the first pulley 306 to rotate through the transmission belt 309, and then the first pulley 306 drives the upper roller 303 to rotate, and then the straw is placed in the feed port 4. At this time, the upper roller 303 cooperates with the lower roller 304 to grind the surface of the straw and cut it into filaments, and then the straw is sent into the interior of the shell 1. After that, the hammer 311 interacts with the toothed plate 302, and the straw is continuously beaten and kneaded, and finally kneaded into filaments and discharged from the discharge port 5.
[0024] Furthermore, six groups of fixed rods 310 are provided, and the fixed rods 310 are distributed in a circular shape with equal intervals. Through the setting of the fixed rods 310, when in use, the fixed rods 310 can drive the hammer pieces 311 to rotate in a circle and hit the toothed plate 302, thereby facilitating the subsequent hammer pieces 311 to continuously hit and rub the straw through interaction with the toothed plate 302.
[0025] Furthermore, the transmission belt 309 is sleeved on the surface of the first pulley 306, and one end of the motor 301 passes through the outer shell 1 and is connected to the connecting rod 305. Through the setting of the transmission belt 309, when in use, the transmission belt 309 can transmit the power of the second pulley 307 to the first pulley 306, ensuring that the upper roller 303 can obtain power to rotate.
[0026] Working principle: First, when kneading and crushing the straw, start the motor 301, and then one end of the motor 301 drives the connecting rod 305 to rotate, and then the connecting rod 305 drives the turntable 308 and the second pulley 307 to rotate, and then the turntable 308 drives the hammer 311 to rotate through the fixed rod 310, and the hammer 311 then continuously rotates around the turntable 308 and hits the toothed plate 302, and at the same time the second pulley 307 drives the first pulley 306 to rotate through the transmission belt 309, and then the first pulley 306 drives the upper roller 303 to rotate, and then the straw is put into the feed port 4, at this time the upper roller 303 cooperates with the lower roller 304 to grind the surface of the straw and cut it into filaments, and then the straw is sent into the interior of the shell 1, and then the straw is continuously hit and rubbed through the interaction between the hammer 311 and the toothed plate 302, and finally After being kneaded into filaments, it is discharged from the discharge port 5. Then, when the shredder is working, the fan 705 is started first. The rotation of the fan 705 will cause the air inside the connecting shell 2 to flow. Due to the suction effect of the fan 705, a negative pressure area is formed inside the connecting shell 2. At this time, the air with dust in the outer shell 1 will enter the connecting shell 2 through the porous partition 701. When the air entering the connecting shell 2 passes through the filter 704, dust and other impurities will be intercepted by the filter 704 and fall to the bottom of the connecting shell 2, and the filtered air will be discharged to the outside through the through holes 703 on the surface of the connecting shell 2, thereby achieving the purpose of dust collection. When the dust inside the connecting shell 2 needs to be cleaned out, the connecting plate 702 can be opened, and the dust can be cleaned at this time, which effectively reduces the dust generated during the straw shredding process, avoids the spread of dust in the equipment and the surrounding environment, and prevents workers from inhaling it.
