The materials fall into the gap between the two rollers through the feeding port on the upper part of the equipment, and are brought into the gap between the two rollers by the friction force and gradually crushed, and the finished materials leak out from the bottom. When encountering materials that are too hard to be crushed, the rollers automatically give way, increasing the gap between the rollers, and the hard materials fall down. With the action of the hydraulic cylinder or spring, the rollers return to the original gap, thereby protecting the machine. By adjusting the gap between the two rollers, the maximum particle size of the product can be controlled;

DETAILED DESCRIPTION

[0045] 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 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 creative work are within the scope of protection of the present invention.

[0046] Embodiment 1

[0047] The present invention provides the following technical solution: a toothed roller crusher, comprising a casing 3, such as Figure 1 The housing 3 includes a first housing and a second housing; two gear roller assemblies 14 are rotatably connected in the housing 3; Figure 2The gear roller assembly 14 includes a main shaft 141, a first gear seat 143 and a second gear seat 145. The first gear seat 143 and the second gear seat 145 are both fixed on the surface of the main shaft 141. After the first gear seat 143 and the second gear seat 145 are arranged one-to-one on the main shaft 141, the gear roller is assembled by arranging the first gear seat 143 and the second gear seat 145 on the main shaft 141 in sequence, which is convenient for actual operation and installation, has strong flexibility, and greatly reduces the production difficulty compared to the gear roller formed by integral casting. The first tooth seat 143 and the second tooth seat 145 are fixed by welding. After the first tooth seat 143 and the second tooth seat 145 are fixed, the first tooth seat 143 and the second tooth seat 145 are connected and welded to the main shaft 141. After welding, annealing is performed by a cutting torch. The first tooth seat 143 and the second tooth seat 145 are of the same size. There are multiple first tooth seats 143 and second tooth seats 145. The multiple first tooth seats 143 and second tooth seats 145 are arranged on the main shaft 141. The first tooth seat 143 is provided with a plurality of slots 144, and the surface of the second tooth seat 145 is provided with a plurality of mounting slots 146. When the first tooth seat 143 and the second tooth seat 145 are stacked together for use, the mounting slots 146 provided on the second tooth seat 145 are blocked by the first tooth seats 143 on both sides, so that the mounting slots 146 form a space for convenient placement of the tooth tip for installation operation. The slots 144 provided on the first tooth seat 143 are provided by placing the first tooth seat 143 and The second tooth seats 145 are sequentially arranged and assembled. When the tooth tip is subsequently worn, a backing plate 1412 is placed in the mounting groove 146. After the backing plate 1412 moves to the bottom of the mounting groove 146, the backing plate 1412 fits against the inner wall of the mounting groove 146 to support the tooth tip subsequently placed in the mounting groove 146, thereby adjusting the length of the tooth tip extending in the mounting groove 146. The thickness of the backing plate 1412 can be increased or decreased according to the wear condition. A tooth tip assembly is provided in the mounting groove 146.The tooth tip assembly includes a first tooth tip 147 and a second tooth tip 1410. The first tooth tip 147 and the second tooth tip 1410 are both trapezoidal on one side of the fitting installation groove 146, which is convenient for fixing. When the first tooth tip 147 is in use, it needs to cooperate with the clamping bevel 148 to be placed in the installation groove 146. By installing a fixing bolt 149 on the clamping bevel 148, the trapezoidal clamping bevel 148 gradually approaches the inside of the installation groove 146, and pressure is generated on one side of the first tooth tip 147, thereby fixing the first tooth tip 147. The first tooth seat 143 and the second tooth seat 145 fit together, so that the two second tooth seats 145 on both sides of the first tooth seat 143 cooperate, and the slots 144 on the first tooth seat 143 and the installation slots 146 on the second tooth seat 145 are aligned, and the offset slots 144 and 146 are formed by cooperation. 11. An inclined block connecting plate 1413 is provided in the offset groove 1411. The inclined block connecting plate 1413 is provided with a threaded groove similar to that on the pressing inclined block 148. When the fixing bolt 149 is gradually tightened, the fixing bolt 149 first contacts one end of the fixing bolt 149 inserted into the installation groove 146. After the inclined block connecting plate 1413 is driven to rotate 90° by the fixing bolt 149, the offset groove 1411 is used to limit the rotation, and the fixing bolt 149 and the pressing inclined block 148 are used to press the tooth tip, and the subsequent removal of the fixing bolt 149 is convenient. When the first tooth tip 147 is installed, the pressing inclined block 148 is 5-15mm higher than the second tooth seat 145. M16×55 bolts are used for 5-10mm, and M16×60 bolts are used for 10-15mm, so as to better cooperate and use;

[0048] The second tooth tip 1410 is a whole. When in use, the second tooth tip 1410 is directly placed in the installation groove 146. The width of the installation groove 146 used by the second tooth tip 1410 gradually increases from the direction close to the main shaft 141 to the direction away from the main shaft 141. The shape of the second tooth tip 1410 is the same as the shape of the installation groove 146 used by the second tooth tip 1410, so that it is convenient to install the second tooth tip 1410 when using it. By installing the fixing bolt 149 on the second tooth tip 1410, the second tooth tip 1410 is directly fixed in the installation groove 146, and subsequent crushing operations are performed, such as Figure 4A discharge port 21 is provided at the bottom of the casing 3, and a receiving hopper 24 is provided on one side of the discharge port 21; sealing structures 142 are provided at both ends of the main shaft 141, and the sealing structure 142 includes a retaining ring, a labyrinth spacer, a self-aligning bearing, a shaft end pressure cover and two labyrinth bearing covers, which are used in conjunction with the gear roller assembly 14 during crushing. A base 1 is provided at the bottom of the casing 3, and a first support plate 2 and a second support plate 4 are connected to the top of the base 1. The first support plate 2 and the second support plate 4 are respectively located on both sides of the casing 3. The first support plate 2 and the second support plate 4 provide support for the gear roller assembly 14, and the sealing structures 142 at both ends of the main shaft 141 pass through the casing 3 and are connected to the first support plate 2 and the second support plate 4 respectively; a plurality of card slots 144 provided on the first gear seat 143 and a plurality of mounting slots 146 provided on the second gear seat 145 are matched one by one, and the card slots 144 and the matching mounting slots 146 are connected, such as Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 The tooth tip assembly includes a first tooth tip 147 and a second tooth tip 1410; Figure 3 , the first support seat 5 and the second support seat 7 are connected to both sides of the base 1, the first shell and the second shell are connected to one side with the first limiting frame 6, the first shell and the second shell are respectively rotatably connected to the two first support seats 5 through the first limiting frame 6, the two second support seats 7 are rotatably connected with the first rotating block 8, the tops of the two first rotating blocks 8 are connected to the hydraulic push rods 9, the output ends of the two hydraulic push rods 9 are connected to the second rotating blocks 11, the top sides of the first shell and the second shell are connected to the second limiting frame 10, and the two second rotating blocks 11 are respectively rotatably connected to the two second limiting frames 10.

[0049] like Fig.16The mounting groove 146 on the second tooth seat 145 is inclined outward on one side at an angle of 5°, and is installed for the first tooth tip 147 inclined on the side. The first tooth tip 147 synchronously placed in the mounting groove 146 is pressed by inserting the pressing inclined block 148 into the mounting groove 146 to prevent the first tooth tip 147 from sliding out of the mounting groove 146 during the crushing process. The number D1 of the slots 144 on the first tooth seat 143 is equal to the number D2 of the mounting grooves 146 on the second tooth seat 145. The diameter R1 of the first tooth seat 143 is equal to the diameter R2 of the second tooth seat 145. 1=R2=1060mm, which can better match the first tooth seat 143 with the second tooth seat 145. The inclined block connecting plate 1413 arranged in the dislocation groove 1411 cooperates with the fixing bolt 149 for tightening operation, which is convenient for the subsequent placement of the pad 1412 for disassembly operation. When the first tooth tip 147 is worn after long-term use, the pad 1412 is placed in the installation groove 146, and the pad 1412 enters the installation groove 146 and fits against the inner wall of the installation groove 146, so that the placed pad 1412 can better support the first tooth tip 147, so that the tooth tip extends out of the installation groove 1 The portion 46 is more stable when contacting the material for crushing. The width of the side of the mounting groove 146 close to the center of the second tooth seat 145 is A1, and the width of the side of the mounting groove 146 away from the center of the second tooth seat 145 is A2, A1=146.8mm, A2=137.6mm, the number of mounting grooves 146 opened on the second tooth seat 145 is determined by the circumference of the second tooth seat 145, π*R2=Q*A2, Q is the number of mounting grooves 146 opened on the second tooth seat 145, the fewer the number of mounting grooves 146 opened, the smaller the number of the second tooth seat 145 installed on the second tooth seat 145. The number of tooth tips 147 is reduced, and the number of first tooth tips 147 installed on the second tooth seat 145 is reduced, which will lead to a reduction in the effect of crushing the material through the first tooth tips 147, resulting in incomplete crushing. A large number of installation grooves 146 will cause the distance between the two installation grooves 146 to become shorter. Therefore, when crushing, the reverse force of the material on the two first tooth tips 147 causes extrusion deformation between the two first tooth tips 147, thereby causing problems in crushing. A groove is set on the surface of the second tooth seat 145, which is 15×15mm, and 5mm is reserved at both ends without grooves.

[0050] Embodiment 2

[0051] Based on Example 1,

[0052] Specifically, Figure 5 A first placement groove 22 is provided on one side of the discharge port 21, and a second placement groove 23 is provided on the side of the first placement groove 22 away from the discharge port 21. Figure 7A receiving hopper 24 is connected to the first placement slot 22. The side of the receiving hopper 24 close to the discharge port 21 is a collecting end. A filter screen 25 is provided at the collecting end. The collected dust first contacts the filter screen 25. The filter screen 25 filters the dust and blocks some larger materials during crushing to prevent the materials from entering the receiving hopper 24, thereby causing the receiving hopper 24 to be blocked. When the materials are crushed, the materials will impact the receiving hopper 24 due to splashing. At this time, the filter screen 25 can protect the receiving hopper 24. Figure 6 The other side of the receiving hopper 24 is connected to a first conveying pipe 26, the other end of the first conveying pipe 26 is connected to a second conveying pipe 27, the second conveying pipe 27 is located in the second placement groove 23, the other end of the second conveying pipe 27 is connected to a chip discharge port 28, the chip discharge port 28 is located on the side of the second placement groove 23 away from the discharge port 21, and the inner wall of the second conveying pipe 27 is provided with a spraying assembly 31, such as Figure 8 and Fig. 9The spray assembly 31 includes a nozzle seat 311. The nozzle seat 311 is square. A diamond-shaped groove 312 is provided on one side of the nozzle seat 311 away from the discharge port 21. The diamond-shaped groove 312 provided on one side of the nozzle seat 311 enables the first nozzle 313 and the second nozzle 314 provided inside to be better used in coordination. The high-pressure gas sprayed by the first nozzle 313 is sprayed toward the chip discharge port 28, so that the air pressure in the second conveying pipe 27 is gradually reduced, thereby gradually reducing the air pressure in the first conveying pipe 26, driving the receiving hopper 24, the first conveying pipe 26 and the second conveying pipe 27 to be in a negative pressure state. This is because one end of the receiving hopper 24 is equipped with the filter screen 25, which generates suction to extract the dust generated by the material crushing, so that the dust passes through the first conveying pipe 26. The first conveying pipe 26 and the second conveying pipe 27 perform a discharge operation at the chip discharge port 28, and the dust in the second conveying pipe 27 is guided by the guide plate 315 for better use. The diamond groove 312 is connected with a first nozzle 313 and a second nozzle 314. There are two second nozzles 314. The first nozzle 313 is located between the two second nozzles 314. The nozzle seat 311 is connected to the guide plate 315 on the side close to the receiving hopper 24. By connecting the water flow in the annular water pipe 29, the water flow passes through the annular water pipe 29 and is sprayed at the two second nozzles 314. The spray direction of the second nozzle 314 is toward the spray trajectory of the first nozzle 313. The water flow sprayed by the first nozzle 313 first contacts the high pressure sprayed by the first nozzle 313. The gas is compressed, and the water flow is turned into water mist after being blown by the gas. While reducing the air pressure in the second conveying pipe 27, the extracted dust is processed, and the extracted dust is adsorbed by the sprayed water mist, so that the dust processing effect is better, and the adsorbed dust and the water mist adsorbing the dust are discharged through the chip discharge port 28. An observation window 12 and an inspection port 13 are arranged on one side of the top of the casing 3. Through the observation window 12, it is convenient for the staff to observe the gear roller assembly 14 inside the casing 3. A feed port 15 is arranged on the top of the casing 3. A bottom plate 18 is connected to one side of the base 1. Two drive motors 20 are connected to the top of the bottom plate 18. The output ends of the two drive motors 20 are connected to a linear hydraulic coupler 19. The two linear hydraulic couplers The output ends of the reducers 19 are connected to the reducers 17, and the output ends of the two reducers 17 are connected to the two main shafts 141 through the elastic pin coupling 16. The gap between the first gear seat 143 and the second gear seat 145 installed on the main shaft 141 is set to 13°. The second delivery pipe 27 is sleeved with an annular water pipe 29 and an annular air duct 30. The annular water pipe 29 is connected to the second nozzle 314, and the annular air duct 30 is connected to the first nozzle 313. The diameter of the second delivery pipe 27 is smaller than the diameter of the first delivery pipe 26. The inner diameter of one end of the first delivery pipe 26 gradually shrinks when it approaches the second delivery pipe 27. The spraying direction of the first nozzle 313 is toward the chip removal port 28, and the two second nozzles 314 are both inclined 45° toward the center position of the second delivery pipe 27.

[0053] Working principle and use process of the present invention: When the present invention is used, according to the use requirements, a plurality of first tooth seats 143 and second tooth seats 145 are sleeved on the main shaft 141, and the first tooth seats 143 and the second tooth seats 145 are inserted and arranged one by one, and the slots 144 on the first tooth seat 143 and the mounting slots 146 on the second tooth seat 145 correspond one by one. After the first tooth seat 143 and the second tooth seat 145 are fully spread on the main shaft 141, the staff connects and fixes the first tooth seat 143 and the second tooth seat 145 by welding. After welding, the welding seam is locally heated with a cutting torch for annealing treatment to make the connection between the first tooth seat 143 and the second tooth seat 145 more tightly, and the staff places the first tooth tip 147 to be used on the second tooth seat 1 45, the first tooth tip 147 is placed in one side of the mounting groove 146, and contacts one side of the inner wall of the mounting groove 146. The first tooth tip 147 is located in the mounting groove 146 formed by the two first tooth seats 143 and the second tooth seat 145. There is still space in the mounting groove 146 after the first tooth tip 147 is placed. When the clamping bevel 148 is placed, the clamping bevel 148 is diamond-shaped, and the narrower side is first inserted into the mounting groove 146. By installing the fixing bolt 149 on the clamping bevel 148, the clamping bevel 148 is pressed into the mounting groove 146. By setting the special shape of the clamping bevel 148, when the clamping bevel 148 gradually enters the mounting groove 146, the clamping bevel 148 applies pressure to the first tooth tip 147 on one side, thereby fixing As the fixed bolt 149 gradually enters the installation groove 146, it first contacts the inclined block connecting plate 1413. Through the continuous rotation of the fixing bolt 149 during the tightening process, the inclined block connecting plate 1413 is driven to rotate 90 degrees, so that the inclined block connecting plate 1413 completely enters the offset groove 1411, and the offset groove 1411 limits the inclined block connecting plate 1413, thereby blocking the inclined block connecting plate 1413 and preventing it from continuing to rotate, thereby cooperating with the pressing inclined block 148 to press the tooth tip on one side, so as to facilitate the subsequent disassembly operation of the fixing bolt 149, and through the cooperation of the installation groove 146, the first tooth tip 147 placed in the installation groove 146 is fixed, and the installation groove on the second tooth seat 145 on the main shaft 141 is fixed. After all the first tooth tips 147 are installed in 146, the main shaft 141 on which the first tooth seat 143 and the second tooth seat 145 are installed is placed in the casing 3. Both ends of the two main shafts 141 are respectively connected to the first support plate 2 and the second support plate 4 through the sealing structure 142. The sealing structure 142 includes a retaining ring, a labyrinth spacer, a self-aligning bearing, a shaft end pressure cover and two labyrinth bearing covers, so as to limit the first support plate 2 and the second support plate 4. In the process of crushing the material, when encountering a material that is too hard to be crushed, the two tooth roller assemblies 14 are moved to both sides under the action of the sealing structure 142, so that the gap between the two tooth roller assemblies 14 becomes larger, so that the material that cannot be crushed falls smoothly, thereby protecting the tooth roller assembly 14.

[0054] When the material needs to be crushed, the material is put into the casing 3 at the feed port 15, and the driving motor 20 is used to drive the two main shafts 141 to rotate in the casing 3, thereby driving the two gear roller assemblies 14 to rotate in opposite directions, and the put material is crushed. The crushed material falls and moves out at the discharge port 21 for subsequent operations. By introducing high-pressure gas into the annular air duct 30, the high-pressure gas passes through the annular air duct 30 and is sprayed at the first nozzle 313 toward the chip discharge port 28, so that the second conveying pipe 27 is in a negative pressure state. During the continuous spraying process of the first nozzle 313, the air pressure at the receiving hopper 24 is gradually reduced to a negative pressure state, so that suction is generated at the feed end of the receiving hopper 24, and dust is sucked into the receiving hopper 24 at the filter screen 25. The filter screen 25 first blocks larger materials to prevent the materials from entering the receiving hopper 2 4, affecting the dust removal effect, and blocking the impact of the broken materials, protecting the receiving hopper 24, the dust enters the second conveying pipe 27 through the first conveying pipe 26, and is guided by the guide plate 315 on one side of the nozzle seat 311 to prevent the nozzle seat 311 from blocking the dust entering the second conveying pipe 27, and the chip discharge port 28 at the other end of the second conveying pipe 27 is discharged, and the water flow is connected to the annular water pipe 29, so that the water flow passes through the annular water pipe 29 and is sprayed out of the second nozzle 314, and the spraying direction of the second nozzle 314 is toward the spraying trajectory of the first nozzle 313, so that the sprayed water flow contacts the gas sprayed by the first nozzle 313, and the water flow is dispersed and atomized. While reducing the air pressure in the second conveying pipe 27, the dust sucked in is adsorbed and processed by the water mist, and the dust processing effect is better;

[0055] After crushing, the staff can observe the condition of the tooth roller assembly 14 inside the casing 3 through the observation window 12. When a single tooth tip is broken or damaged, the two hydraulic push rods 9 work, the two hydraulic push rods 9 shorten, drive the second limit frame 10 to move, and the first rotating block 8 and the second rotating block 11 rotate and cooperate, thereby driving the first shell and the second shell to rotate synchronously to both sides, exposing the tooth roller assembly 14 located in the casing 3. The staff removes the fixing bolt 149 on the clamping bevel 148 on the side of the damaged tooth tip, and takes out the clamping bevel 148 from the mounting groove 146, so that the damaged first tooth tip 147 can be taken out from the mounting groove 146, so as to replace the new first tooth tip 147. After replacement, the clamping bevel 148 is placed in the mounting groove 146 in accordance with the first tooth tip 147, and fixed by the fixing bolt 149, which is convenient for subsequent use, and can better carry out accurate repairs on the damaged parts, greatly saving the repair costs. When the material is crushed for a long time, the tooth tip will be worn, which will lead to a worse crushing effect. The staff can take out the tooth tip and the clamping bevel 148 in the installation groove 146, and put the matching pad 1412 into the installation groove 146. By pushing the pad 1412 to the bottom of the installation groove 146, after the pad 1412 is put in, the first tooth tip 147 to be used is put into the installation groove 146. At this time, the first tooth tip 147 cannot be inserted into the installation groove 146 further due to the pad 1412 placed in the installation groove 146, so that the extended length of the first tooth tip 147 becomes longer, so that the tooth tip height can be adjusted for the worn tooth tip for crushing, effectively avoiding the situation that the worn tooth tip cannot be used, and greatly reducing the cost of wear. After maintenance, the hydraulic push rod 9 is extended to drive the first shell and the second shell to rotate close on the base 1, thereby forming a complete shell for subsequent crushing operations.
