[0021] The ice-breaking shaft 3 is horizontally slidably mounted with an auger shaft 4 through a sliding assembly, and an auger blade 5 is fixedly sleeved on the auger shaft 4. Two slide grooves 38 are provided on the ice-breaking shaft 3. The sliding assembly includes two sliding blocks 39 respectively slidably mounted in the two slide grooves 38.

The auger shaft 4 is slidably installed on the ice-breaking shaft 3 through the sliding block 39, and can move horizontally on the ice-breaking shaft 3 for a short distance. When the ice-breaking shaft 3 rotates, the auger shaft 4 can be driven to rotate together through the sliding assembly, and then the auger blades 5 are driven to rotate through the auger shaft 4. The auger blades 5 are installed in the side discharge cover 2. When the auger blades 5 come into contact with the accumulated snow and rotate, the accumulated snow will be driven to one side, thereby discharging the accumulated snow to one side of the snowplow. The continuous rotation of the auger blades 5 realizes the continuity of snow discharge and improves work efficiency.

Under the action of the elastic force of the first telescopic spring 17, the slider 15 contacts the block 16, and the baffle 8 just blocks the pipe opening of the discharge pipe 7. At this time, the industrial salt in the storage box 6 cannot be discharged. When the industrial salt needs to be discharged, the slider 15 can be driven to move in the direction of the first telescopic spring 17 to compress the first telescopic spring 17, and then the baffle 8 is driven to move by the slider 15. During the movement, the baffle 8 will slowly open the pipe opening of the discharge pipe 7. Under the action of the support rod 14 and the slider 15, the baffle 8 can only move horizontally.

[0023] A plurality of mounting holes 10 are provided on the side of the auger blade 5, and vertical rods 11 are installed in the plurality of mounting holes 10 through mounting components. The plurality of vertical rods 11 correspond to the plurality of retaining frames 9 respectively, and the corresponding vertical rods 11 and retaining frames 9 are in the same vertical plane. The mounting component includes a support frame 18 fixedly installed in the mounting hole 10, a sealing push block 19 fixedly installed at one end of the vertical rod 11, and a second telescopic spring 20 sleeved on the vertical rod 11. The vertical rod 11 is vertically slidably installed on the support frame 18, and the two ends of the second telescopic spring 20 are fixedly connected to the support frame 18 and the sealing push block 19 respectively; The sealing push block 19 is sealingly slidably installed in the mounting hole 10. Under the support of the second telescopic spring 20, the vertical rod 11 is vertically slidably installed in the mounting hole 10. The vertical rod 11 on the auger blade 5 and the corresponding baffle 8 are in the same vertical plane. When the auger blade 5 rotates, it will drive the vertical rod 11 to rotate around the auger shaft 4. When the vertical rod 11 rotates, it will contact the baffle frame 9 on the baffle 8 and drive the baffle 8 to move between the two support rods 14, thereby opening the mouth of the discharge pipe 7.

[0024] An annular cavity 23 is provided inside the auger shaft 4, and a sealing ring 21 is sealed and slidably installed inside the annular cavity 23. A plurality of movable holes connected to the annular cavity 23 are provided at one end of the auger shaft 4 close to the driving motor 13, and movable rods 22 are horizontally slidably installed in the plurality of movable holes. One end of the plurality of movable rods 22 is fixedly connected to the sealing ring 21, and one end of the movable rod 22 away from the sealing ring 21 is fixedly connected to the ice breaking rack 1. A plurality of connecting holes connected to the plurality of mounting holes 10 are provided inside the annular cavity 23; When the auger blade 5 is discharging snow at the side, the accumulated snow will also exert a reaction force on the auger blade 5. When there is more snow, the reaction force will be greater. Under the action of the reaction force, the auger shaft 4 will be driven to move in the direction of the drive motor 13. Under the action of the moving rod 22, the sealing ring 21 will move relatively in the annular cavity 23. At this time, the air pressure in the sealing ring 21 becomes greater. Under the action of the air pressure, the sealing push block 19 in the mounting hole 10 will be driven to move in the direction of the vertical rod 11. At this time, the length of the vertical rod 11 extending from the mounting hole 10 will be When the vertical rod 11 contacts the retaining frame 9, the vertical rod 11 rotates around the ice-breaking axis 3, so that the vertical rod 11 will separate from the retaining frame 9, and the contact time between the vertical rod 11 and the retaining frame 9 is related to the length of the vertical rod 11 extending from the mounting hole 10. The longer the vertical rod 11 extends from the mounting hole 10, the longer the contact time with the retaining frame 9, and thus the longer the distance the baffle 8 moves, the greater the degree of opening of the discharge pipe 7, and the more industrial salt is discharged. When there is less snow, the discharge of industrial salt will correspondingly decrease. When there is less snow, the internal pressure of the annular cavity 23 will push the auger shaft 4 on the ice-breaking shaft 3 to move away from the drive motor 13 through the sealing ring 21 and the moving rod 22 .

[0025] A plurality of conical tubes 24 are provided in the material storage box 6, and the conical tubes 24 are fixedly installed in the material storage box 6 by L-shaped rods 25. The plurality of conical tubes 24 are respectively located above the plurality of discharge holes, and a conical friction block 26 is rotatably installed in the conical tube 24, and a fixing hole is provided on the conical friction block 26, and a fixing rod 27 is vertically fixedly installed in the fixing hole, and a spur gear 28 is fixedly installed on the fixing rod 27, and a through hole is provided on the side of the material storage box 6, and a rack rod 29 is horizontally slidably installed in the through hole, and a plurality of spur gears 28 are meshed and connected with the rack rod 29, and a spring rod 30 is horizontally fixedly installed on the rack rod 29, and one end of the spring rod 30 is fixedly connected to the inner wall of the material storage box 6, and a rectangular hole is provided on the side row cover 2, and a translation rod 31 is horizontally slidably installed in the rectangular hole, and one end of the translation rod 31 is fixedly connected to the rack rod 29, and the other end is in sliding contact with the surface of the auger blade 5; One end of the translation rod 31 is in sliding contact with the surface of the auger blade 5. When the auger blade 5 is rotating, the translation rod 31 will move horizontally along the spiral surface of the auger blade 5 until the translation rod 31 moves to one end of the auger blade 5 and separates from the auger blade 5. At this time, the rack rod 29 will drive the translation rod 31 to move back under the elastic force of the spring rod 30 until the translation rod 31 contacts the surface of the auger blade 5 again. The rack rod 29 can move back and forth horizontally under the action of the translation rod 31, thereby driving the conical friction block 26 to reciprocate in the conical tube 24 through the spur gear 28. The conical tube 24 is made of metal copper. When the conical friction block 26 rotates relative to the conical tube 24, a large amount of heat is generated under the action of friction. The generated heat will be transferred to the industrial salt near the conical tube 24, so that the temperature of the industrial salt increases. When the industrial salt contacts the accumulated snow, the temperature of the industrial salt is higher than the temperature of the accumulated snow, and a certain temperature difference exists between the accumulated snow and the industrial salt. When the temperature difference is large, the melting of the accumulated snow can be accelerated, further improving the melting efficiency of the accumulated snow.

[0026] A plurality of stirring blades 32 are fixedly mounted on the fixed rod 27 , and the plurality of stirring blades 32 are all located in the discharge pipe 7 . When the conical friction block 26 rotates in the conical tube 24 , the plurality of stirring blades 32 are driven to rotate in the discharge pipe 7 through the fixed rod 27 . The rotating stirring blades 32 can prevent industrial salt from accumulating in the discharge pipe 7 and blocking the discharge pipe 7 .

[0027] An air pipe 33 is fixedly installed on the ice breaking rack 1, one end of the air pipe 33 is inserted into the motor cover 12, and the other end is inserted into the storage box 6. A plurality of air outlet pipes 34 are fixedly connected to the surface of the air pipe 33, and the plurality of air outlet pipes 34 are all located in the storage box 6. A first one-way valve that only allows gas to flow from the motor cover 12 into the storage box 6 is installed in the air pipe 33, and a second one-way valve that only allows gas to flow from the air pipe 33 into the storage box 6 is installed in the air outlet pipe 34. An L-shaped support rod 35 is fixedly installed on the rack rod 29, a push-pull rod 36 is fixedly installed on one end of the support rod 35, and a sealing plug 37 is fixedly installed on one end of the push-pull rod 36. The sealing plug 37 is sealingly slidably installed in the air pipe 33; When the driving motor 13 is operating, a large amount of heat will be generated in the motor cover 12, and the generated heat can be transported to the storage box 6 through the air pipe 33. When the push-pull rod 36 drives the sealing plug 37 to move back and forth in the air pipe 33, the hot air in the motor cover 12 will be sucked into the air pipe 33, and then the hot air in the air pipe 33 will be discharged into the storage box 6 from the air outlet pipe 34. The second one-way valve can ensure that when the hot air is sucked into the air pipe 33, the gas in the storage box 6 will not enter the air pipe 33. The first one-way valve can ensure that when the hot air is discharged from the air pipe 33 into the storage box 6, the hot air in the air pipe 33 will not be discharged from the other end of the air pipe 33.

[0028] In the present invention, when snow is removed, the driving motor 13 is started to drive the ice breaking shaft 3 to rotate, and then the auger blade 5 is driven to rotate through the auger shaft 4. When the auger blade 5 contacts the accumulated snow, it will drive the accumulated snow to move to one side during the rotation process. When the auger blade 5 continues to rotate, the continuity of snow removal is achieved, thereby improving the working efficiency. When the auger blades 5 rotate, they will drive the multiple vertical rods 11 on the auger blades 5 to rotate around the ice-breaking shaft 3. When the vertical rods 11 rotate to the bottom of the storage box 6, they will contact the baffle frame 9 on the baffle plate 8 and drive the baffle plate 8 to move horizontally through the baffle frame 9, thereby opening the nozzle of the discharge pipe 7. At this time, the industrial salt in the storage box 6 will pass through the discharge pipe 7 and be discharged from the storage box 6 until the baffle frame 9 is separated from the vertical rods 11. At this time, the baffle plate 8 will block the nozzle of the discharge pipe 7 again under the action of the elastic force of the first telescopic spring 17, and the discharged industrial salt will fall onto the snow on the auger blades 5 and mix with the snow. When the industrial salt is mixed with the snow, the industrial salt will dissolve and release heat to melt the snow, thereby preventing the snow from freezing on the auger blades 5, preventing the snow discharge from affecting the spiral side discharge structure, and ensuring the snow discharge efficiency; At the same time, the snow cleared by the spiral side discharge structure will accumulate on one side of the road, and during the cleaning process, an appropriate amount of industrial salt is mixed into the snow. The industrial salt can effectively promote the melting of the snow accumulated on one side of the road.

[0029] When the auger blade 5 accumulates snow on the side, the accumulated snow will also exert a reaction force on the auger blade 5. Under the action of the reaction force, the auger shaft 4 and the auger blade 5 will be driven to move horizontally on the ice-breaking shaft 3 toward the driving motor 13. When there is more snow, the reaction force will be greater, and the distance moved by the auger shaft 4 and the auger blade 5 will be greater. When the auger shaft 4 moves horizontally on the ice-breaking shaft 3, under the action of the moving rod 22, the sealing ring 21 will be pushed to move horizontally in the annular cavity 23. When the sealing ring 21 moves, the pressure in the annular cavity 23 will increase, and the annular cavity 23 is connected with the mounting hole 10 through the connecting hole, so that the pressure in the mounting hole 10 increases. Under the action of the pressure chamber, the sealing push block 19 will be driven to move in the direction of the second telescopic spring 20. As the auger shaft 4 moves more, the sealing push block 19 moves more, and the second telescopic spring 20 is compressed more. As a result, the length of the vertical rod 11 extending from the mounting hole 10 will be longer. When the vertical rod 11 contacts the retaining frame 9, the length of the vertical rod 11 extending from the mounting hole 10 is longer, and the contact time with the retaining frame 9 is longer, so that the distance moved by the baffle 8 will be longer, and the opening time of the nozzle of the discharge pipe 7 will be longer, so that more industrial salt will be discharged from the discharge pipe 7. When the amount of snow processed by the auger blades 5 is less, the distance that the auger shaft 4 moves on the ice-breaking shaft 3 will also be shorter, so that the length of the vertical rod 11 extending from the mounting hole 10 will be shorter, that is, the amount of industrial salt discharged from the discharge pipe 7 will also be less. The length of the vertical rod 11 when in contact with the retaining frame 9 can be controlled according to the amount of snow accumulation, thereby controlling the size of the opening of the discharge pipe 7, and further controlling the amount of industrial salt discharged from the discharge pipe 7. The discharge of industrial salt can be controlled according to the amount of snow accumulated during snow removal, thereby avoiding waste of industrial salt and effectively saving costs.

[0030] When the auger blade 5 rotates, it drives the rack rod 29 to reciprocate in the storage box 6 through the translation rod 31. During the movement of the rack rod 29, it drives the conical friction block 26 to rotate in the conical tube 24 through the spur gear 28. Heat is generated by the friction between the two, and the generated heat is transferred to the industrial salt near the conical tube 24, so that the temperature of the industrial salt is increased, thereby ensuring that when the industrial salt is added to the snow, there is a certain temperature difference between the snow and the industrial salt. In the case of a large temperature difference, the melting of the snow can be accelerated, and the snow melting efficiency is further improved; When the conical friction block 26 rotates, it will drive multiple stirring blades 32 to rotate in the discharge pipe 7 through the fixed rod 27. During the rotation process, the stirring blades 32 will continuously drive the industrial salt in the discharge pipe 7 to rotate, thereby preventing the industrial salt from accumulating in the discharge pipe 7 and blocking the discharge pipe 7, ensuring that the industrial salt can be discharged from the discharge pipe 7 smoothly.

[0031] When the rack rod 29 reciprocates in the storage box 6, it will drive the sealing plug 37 to reciprocate horizontally in the air pipe 33 through the support rod 35 and the push-pull rod 36. During the reciprocating movement of the sealing plug 37, the heat generated in the motor cover 12 will be absorbed into the air pipe 33, and then discharged into the storage box 6 through the outlet pipe 34, thereby recycling the heat generated by the drive motor 13 and further heating the industrial salt to achieve a better heating effect.
