Description

Technical Field

[0001] The invention relates to the technical field of asphalt mixing equipment, and in particular to a processing equipment for road asphalt mixture. Background Art

[0002] Asphalt mortar mixing equipment is a device for mixing cement, mortar and asphalt. After a certain proportion of the mixture is placed in its mixing drum, the motor is started to rotate the stirring shaft connected to it, so that the stirring paddle stirs the mixture. The existing asphalt mortar mixing equipment does not have a rotating mechanism that can facilitate the rapid discharge of the mixed materials, which causes inconvenience in use and has certain limitations.

[0003] In order to solve the above problems, a Chinese patent with publication number CN211993567U discloses an asphalt mortar mixing device for road engineering, including a support plate, fixed rods are fixedly connected to both sides of the top of the support plate, and a top plate is fixedly installed on the top of the fixed rod, the top of the top plate is connected to a motor 1, and the bottom of the motor 1 is connected to a connecting block 1 through a connecting shaft, and the bottom of the connecting block 1 is connected to a connecting block 2. The device can loosen its hand-tightened bolt 2, and then pull its handle, so that its support plate can rotate between the rotating shaft and the inner wall of the square plate, and the mixing drum connected to the support plate can rotate, which is convenient for the material inside the mixing drum to be quickly discharged, improves the discharge efficiency, and enhances the practicality of the device.

[0004] The above-mentioned device has the following problems during actual use: 1. The mixture contains viscous substances such as cement, mortar, asphalt, etc. When the mixture is poured into the mixing drum, a part of the viscous substances will contact the inner wall of the mixing drum. Since the viscous substances have a certain viscosity, the viscous substances will adhere to the inner wall of the mixing drum. If the inner wall of the mixing drum is not cleaned, the utilization rate of the mixture will be reduced, that is, the mixing effect of the mixture will be insufficient and incomplete; 2. If the viscous substances are not processed for a long time, the viscous substances will accumulate on the inner wall of the mixing drum to form a large volume of viscous deposits. The viscous deposits can easily block the feed port of the mixing drum. When the device is used for stirring, the feed port of the mixing drum will be directly blocked by the large volume of viscous deposits, and the mixture can no longer be stirred by the mixing drum, which reduces the working efficiency of the mixing drum in stirring and mixing the mixture. Summary of the invention

[0005] The invention provides a processing device for road asphalt mixture, so as to solve the problem that the mixture adheres to the inner wall of a mixing drum when the mixture is stirred by the existing stirring equipment.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: comprising a cylindrical barrel with an inlet and an outlet, and also comprising a cleaning mechanism arranged in the cylindrical barrel; the cleaning mechanism comprises a driving shaft, a cleaning assembly symmetrically arranged on both sides of the driving shaft along the axial direction of the driving shaft, and a driving assembly for driving the driving shaft to rotate; the driving shaft is rotatably connected to the cylindrical barrel; the cleaning assembly comprises a connecting block, a rotating shaft, a cleaning part symmetrically arranged on both sides of the rotating shaft along the axial direction of the rotating shaft, and a power part for driving the rotating shaft to rotate; the connecting block is fixedly connected to the driving shaft; the rotating shaft is rotatably connected to the connecting block; the cleaning part comprises a plurality of cleaning units equidistantly arranged along the axial direction of the rotating shaft; the cleaning unit comprises a fixed block, a rotating shaft, an elastic disk, a plurality of stirring blades, a plurality of elastic blocks, and a moving part for driving the rotating shaft to rotate forward and reverse; the fixed block is fixedly connected to the rotating shaft; the rotating shaft is rotatably connected to the fixed block; a plurality of stirring blades are equidistantly arranged along the axial direction of the rotating shaft, and the stirring blades are fixedly connected to the rotating shaft; the elastic disk is fixedly connected to the rotating shaft; a plurality of elastic blocks are all fixedly connected to the elastic disk, and one end of the elastic block away from the elastic disk is attached to the inner wall of the cylindrical barrel.

[0007] The principles and advantages of this solution are:

[0008] 1. Workers pour cement, mortar and asphalt into the cylindrical barrel along the inlet to form a mixture. After the mixture is placed, the driving shaft is driven to rotate through the driving assembly; during the rotation of the driving shaft, the connecting block rotates synchronously; during the rotation of the connecting block, the rotating shaft rotates synchronously, so the rotating shaft moves circumferentially with the driving shaft as the center and the length of the connecting block as the radius; during the movement of the rotating shaft, the fixed block moves synchronously; during the movement of the fixed block, the rotating shaft moves synchronously; during the circumferential movement of the rotating shaft, the rotating shaft is driven to rotate forward and reverse through the moving parts; therefore, while the rotating shaft moves circumferentially, it can also rotate on its own; during the movement of the rotating shaft, the elastic disk moves synchronously; during the movement of the elastic disk, the elastic block moves synchronously.

[0009] Through the above movement, since the elastic block is in contact with the inner wall of the cylindrical tube, the circumferential movement of the elastic block can clean the sticky substances on the circumferential direction of the inner wall of the cylindrical tube, thereby making the sticky substances at any position on the circumferential direction of the inner wall of the cylindrical tube be cleaned under the action of the elastic block; and, since the elastic block can also rotate while making the circumferential movement, the elastic block has a certain force, and the elastic block can clean the sticky substances adhering to the inner wall of the cylindrical tube more fully and completely, thereby ensuring that the sticky substances on the inner wall of the cylindrical tube are thoroughly cleaned; that is, through the movement of the elastic block, the sticky substances adhering to the inner wall of the cylindrical tube can be cleaned, so that the sticky substances can be mixed into the mixture again for stirring, thereby improving the utilization rate of the mixture, enhancing the stirring effect, and improving the stirring efficiency.

[0010] 2. During the movement of the rotating shaft, the rotating shaft can break up and stir the mixture in the circumferential direction of the cylindrical barrel when it revolves, so that the mixture in the circumferential direction of the cylindrical barrel has fluidity, and the mixture in the circumferential direction of the cylindrical barrel can continuously change its position, which increases the movement path of the mixture and speeds up the full mixing of the mixture, thereby shortening the mixing time and improving the mixing efficiency.

[0011] During the rotation of the rotating shaft, the stirring blades move synchronously; when the stirring blades rotate, for viscous liquids such as cement, mortar, asphalt, etc., which have poor fluidity, the stirring blades can continuously change the position of the mixture on the upper part of the rotating shaft and the mixture on the lower part of the rotating shaft when they move along the circumferential direction of the cylindrical barrel, thereby expanding the range of the mixture being stirred. Therefore, the rotation of the stirring blades can stir the mixture at any position in the height direction of the cylindrical barrel, ensuring that the mixture is stirred more completely and evenly.

[0012] In summary, with the joint action of the rotating shaft and the stirring blades, the mixture in the cylindrical barrel can be fully and evenly stirred, that is, the mixture is mixed more completely and thoroughly, which fully guarantees the quality of the mixture after stirring.

[0013] Furthermore, it also includes a linkage component arranged on the rotating shaft; the linkage component includes a disc and a linkage part symmetrically arranged on both sides of the rotating shaft along the axial direction of the rotating shaft; the disc is fixedly connected to the rotating shaft; the linkage part includes a linkage block, a plurality of linkage units equidistantly arranged along the length direction of the linkage block, a through hole opened on the disc, and a power unit for driving the linkage block to perform vertical reciprocating motion; the linkage unit includes a side block and a plurality of throwing blocks symmetrically arranged on both sides of the side block along the length direction of the side block; the linkage block is vertically slidably connected to the through hole; the side block is fixedly connected to the linkage block; the throwing block is fixedly connected to the side block.

[0014] During the circumferential motion of the rotating shaft, the disc moves synchronously; during the motion of the disc, the linkage block moves synchronously; during the circumferential motion of the linkage block, the linkage block is driven by the power unit to make vertical reciprocating motion; therefore, while the linkage block makes circumferential motion, it can also make vertical reciprocating motion; during the motion of the linkage block, the side block moves synchronously; during the motion of the side block, the throwing block moves synchronously; during the vertical reciprocating motion of the throwing block, the throwing block can drive the mixture to continuously make vertical reciprocating motion, thereby changing the position of the mixture in the height direction in the cylindrical barrel, and realizing the exchange of position between the mixture above the throwing block and the mixture below the throwing block, thereby ensuring that the mixture can be mixed more fully and completely; and, since the throwing block can also make circumferential motion, the range of action of the throwing block is expanded, so that the mixture in the cylindrical barrel can exchange positions in the height direction, thereby promoting more uniform mixing of the mixture, further ensuring more comprehensive mixing of the mixture, enhancing the stirring effect, and improving the stirring efficiency.

[0015] In summary, through the circumferential and vertical movement of the side blocks, the range of action of the throwing blocks is expanded and the effect of the throwing blocks is enhanced. That is, the throwing blocks can drive the mixture in the cylindrical barrel to interact in a comprehensive and sufficient manner, ensuring the quality after mixing and enhancing the use effect of the mixture.

[0016] Furthermore, it also includes an auxiliary part arranged on the side block; the auxiliary part includes a slider, an impact block, a side hole opened on the side block, and a driving unit for driving the slider to reciprocate along the length direction of the side block; the slider is slidably connected to the side hole; the impact block is fixedly connected to the slider; the impact block can slide in and out of the side hole, and the inner wall of the cylindrical tube is located on the movement trajectory of the impact block.

[0017] During the circumferential movement of the edge block, the driving unit drives the slider to perform reciprocating motion along the length direction of the edge block; during the movement of the slider, the impact block moves synchronously; during the movement of the impact block, the viscous material on the circumferential direction of the inner wall of the cylindrical tube can be impacted, so the viscous material at any position on the circumferential direction of the inner wall of the cylindrical tube is impacted by the impact block; similarly, when the edge block moves vertically, the viscous material at any position on the height direction of the inner wall of the cylindrical tube is also impacted by the impact block.

[0018] Through the above-mentioned movement, during the impact of the impact block, on the one hand, the amount of sticky material adhering to the inner wall of the cylindrical barrel can be reduced, and on the other hand, the adhesion force of the sticky material adhering to the inner wall of the cylindrical barrel can be weakened, that is, the sticky material becomes loose; the loosened sticky material can be mixed into the mixture again under the action of the elastic block, thereby reducing the probability of the feed port being blocked, reducing the amount of the mixture adhering to the inner wall of the cylindrical barrel, improving the utilization rate of the mixture, ensuring that the mixture can be fully collected, and improving the subsequent construction effect of the mixture.

[0019] In summary, under the joint action of the circumferential movement and vertical movement of the impact block, the sticky material on the inner wall of the cylindrical barrel can be comprehensively and thoroughly treated, that is, the sticky material on the inner wall of the cylindrical barrel can be acted upon by the impact block, so that the sticky material can be mixed into the mixture again to complete the mixing operation.

[0020] Furthermore, the impact block is a rubber block; it also includes an auxiliary unit arranged on the rubber block; the auxiliary unit includes a conical block and an auxiliary hole opened on the rubber block; the conical block is located in the auxiliary hole, and the conical block is fixedly connected to the slider.

[0021] During the movement of the impact block, the conical block moves synchronously; during the movement of the conical block, the conical block exerts a greater force on the sticky material than the impact block, and the impact effect is better. On the one hand, it can reduce the amount of sticky materials with strong viscosity adhering to the inner wall of the cylindrical tube, and on the other hand, it can further weaken the adhesion of the sticky material to the inner wall of the cylindrical tube, that is, the sticky material becomes loose; the loosened sticky material is easier to clean up under the action of the elastic block, which further improves the working efficiency of the elastic block.

[0022] The setting of the conical block in the auxiliary hole is to promote the stability of the movement of the impact block when the impact block is subjected to the reaction force of the inner wall of the cylindrical tube and moves in the opposite direction along the length direction of the side block. On the other hand, it can ensure that the impact block will not break due to excessive deformation, thereby achieving the effect of reinforcing the impact block.

[0023] Since the conical block can also make circumferential motion, it can impact the sticky substances on the circumferential direction of the inner wall of the cylindrical tube when it moves circumferentially. Therefore, the sticky substances at any position on the circumferential direction of the inner wall of the cylindrical tube are impacted by the action of the conical block. Similarly, when the conical block moves vertically, the sticky substances at any position on the height direction of the inner wall of the cylindrical tube are also impacted by the action of the conical block.

[0024] In summary, through the circumferential and vertical movements of the conical block, the viscous matter on the inner wall of the cylindrical barrel can be comprehensively and thoroughly processed, that is, the viscous matter on the inner wall of the cylindrical barrel can be impacted by the conical block, which further ensures that the viscous matter can be completely mixed into the mixture, thereby improving the utilization rate of the mixture.

[0025] Furthermore, it also includes a plurality of auxiliary blocks equidistantly arranged along the length direction of the linkage block; a top hole is opened on the auxiliary block for the linkage block to make vertical reciprocating motion; the auxiliary block is fixedly connected to the rotating shaft; and the linkage block is located in the top hole.

[0026] During the circumferential motion of the rotating shaft, the auxiliary block moves synchronously; during the rotation of the auxiliary block, the auxiliary block has a greater force than the rotating shaft and a better stirring effect, so that when the auxiliary block further stirs the mixture in the cylindrical barrel, the auxiliary block can break up the clumped mixture; after the mixture is broken up, the mixture can be more fully and comprehensively stirred and mixed under the joint action of the throwing block and the stirring blade, thereby improving the stirring efficiency.

[0027] Furthermore, it also includes a cutting part arranged on the auxiliary block; the cutting part includes a first wedge block, a linkage hole opened on the auxiliary block, and cutting units symmetrically arranged on both sides of the first wedge block along the length direction of the first wedge block; the first wedge block is fixedly connected to the top of the side block, and the first wedge block can make vertical reciprocating motion in the linkage hole; the cutting unit includes a second wedge block, a cutting knife, a first spring, and a guide groove opened on the auxiliary block; the guide groove is connected to the linkage hole; the second wedge block is slidably connected to the guide groove, and the second wedge block is located on the movement trajectory of the first wedge block; the cutting knife is fixedly connected to the second wedge block, and the cutting knife can slide in and out of the guide groove; the two ends of the first spring are respectively connected to the second wedge block and the guide groove.

[0028] During the vertical reciprocating motion of the edge block, the first wedge block moves synchronously; during the motion of the first wedge block, since the second wedge block is located on the motion trajectory of the first wedge block, when the first wedge block abuts against the second wedge block, the first wedge block can drive the two second wedge blocks to move away from each other along the width direction of the auxiliary block, and the first spring is compressed. When the first wedge block no longer abuts against the second wedge block, the second wedge block is reset under the action of the first spring, and the two second wedge blocks approach each other along the width direction of the auxiliary block; therefore, the two second wedge blocks can approach or move away from each other; during the motion of the second wedge block, the cutting knife moves synchronously.

[0029] During the movement of the cutting knife, the cutting tool has a certain force. The cutting knife can cut and break up the relatively viscous and clumped mixture, so that the viscous mixture is dispersed and mixed again with other mixtures in the cylindrical barrel, thereby enhancing the stirring effect of the mixture and further ensuring the quality of the mixed mixture; and, since the cutting knife can also move in a circumferential direction, the range of action of the cutting knife is expanded, the effect of the cutting knife is enhanced, and it is ensured that the viscous mixture in the cylindrical barrel can be dispersed under the action of the cutting knife, that is, the mixture is mixed more evenly and thoroughly.

[0030] Furthermore, it also includes an annular rack; the annular rack is fixedly connected to the cylindrical tube; the power part is a first gear; the first gear is fixedly connected to the rotating shaft, and the first gear is meshed with the annular rack.

[0031] During the circumferential motion of the rotating shaft, the first gear moves synchronously; during the motion of the first gear, the first gear is engaged with the annular rack, thereby rotating the first gear; during the rotation of the first gear, the rotating shaft moves synchronously, so the rotating shaft can rotate while performing circumferential motion.

[0032] Furthermore, the moving parts are a second gear and a rack; the second gear is fixedly connected to the rotating shaft; the rack is fixedly connected to the linkage block, and the rack is meshed with the second gear.

[0033] During the vertical reciprocating motion of the linkage block, the rack moves synchronously; during the vertical downward motion of the rack, the rack is engaged with the second gear, so that the second gear can rotate forward; similarly, during the vertical upward motion of the rack, the second gear reverses; therefore, the second gear can rotate forward and reverse; during the rotation of the second gear, the rotating shaft rotates synchronously.

[0034] Furthermore, it also includes a power member symmetrically arranged on both sides of the driving shaft along the axial direction of the driving shaft; the power member includes a vertical block, a short shaft, a cam, a worm gear, a hollow block, and a second spring; the vertical block is fixedly connected to the connecting block; the short shaft is rotatably connected to the vertical block; the cam and the worm gear are both fixedly connected to the short shaft; the hollow block is vertically slidably connected to the vertical block; the cam is abutted against the hollow block; the two ends of the second spring are respectively connected to the hollow block and the vertical block; the rotating shaft includes a rotating shaft body and a worm; the worm gear is meshed with the worm; the power unit is a third spring; the two ends of the third spring are respectively connected to the linkage block and the disc; the linkage block is abutted against the hollow block.

[0035] During the rotation of the worm, the worm wheel rotates due to the meshing of the worm wheel and the worm; during the rotation of the worm wheel, the short shaft rotates synchronously; during the rotation of the short shaft, the cam rotates synchronously; during the rotation of the cam, when the raised portion of the cam abuts against the hollow block, the second spring is compressed during the vertical downward movement of the hollow block, and when the raised portion of the cam no longer abuts against the hollow block, the hollow block is reset under the action of the second spring, and the hollow block moves vertically upward; therefore, the hollow block can perform vertical reciprocating motion.

[0036] The hollow block moves vertically downward, the linkage block moves synchronously, and the third spring is compressed; during the vertical upward movement of the hollow block, the linkage block is reset under the action of the third spring, and the linkage block moves vertically upward; therefore, the linkage block can perform vertical reciprocating motion.

[0037] Furthermore, it also includes an auxiliary part arranged on the linkage block; the auxiliary part includes a plurality of arc-shaped protrusions, a linkage rod, a fourth spring, and a vertical groove opened on the linkage block; two adjacent arc-shaped protrusions are fixedly connected to form an arc-shaped block; the arc-shaped block is vertically slidably connected to the vertical groove; the linkage rod is fixedly connected to the arc-shaped block, the linkage rod can slide in and out of the vertical groove, and the linkage rod is abutted against the bottom of the cylindrical tube; the two ends of the fourth spring are respectively connected to the vertical groove and the linkage rod; the driving unit includes a spherical wedge block and a fifth spring; the side hole is connected to the vertical groove, the spherical wedge block is fixedly connected to the slider, the spherical wedge block extends into the vertical groove, the spherical wedge block is abutted against the arc-shaped protrusion, and the spherical wedge block is located on the movement trajectory of the arc-shaped protrusion; the two ends of the fifth spring are respectively connected to the spherical wedge block and the side hole.

[0038] During the vertical downward movement of the linkage block, the linkage rod moves synchronously; during the vertical downward movement of the linkage rod, the linkage rod is subjected to the reaction force of the inner wall of the cylindrical tube, thereby causing the linkage rod to move vertically upward relative to the vertical groove, and the fourth spring is stretched; during the vertical upward movement of the linkage rod, the arc-shaped protrusion moves synchronously; during the movement of the arc-shaped protrusion, since the spherical wedge block is abutted against the arc-shaped protrusion, the spherical wedge block moves to a position close to the inner wall of the cylindrical tube under the drive of the arc-shaped protrusion, the fifth spring is compressed, and the slider moves synchronously; similarly, during the vertical upward movement of the linkage block, the linkage rod is reset under the action of the fourth spring, and the spherical wedge block is reset under the action of the fifth spring; therefore, the slider can reciprocate along the length direction of the side hole.

[0062] The specific implementation process is as follows:

[0063] Workers pour cement, mortar and asphalt into the cylindrical tube 1 along the inlet to form a mixture. After the mixture is placed, the motor 41 is started to drive the drive shaft 4 to rotate; during the rotation of the drive shaft 4, the connecting block 5 rotates synchronously; during the rotation of the connecting block 5, the rotating shaft rotates synchronously, so the rotating shaft moves circumferentially with the drive shaft 4 as the center and the length of the connecting block 5 as the radius; during the circumferential movement of the rotating shaft, the first gear 25 moves synchronously; during the movement of the first gear 25, since the first gear 25 is meshed with the annular rack 24, the first gear 25 rotates; during the rotation of the first gear 25, the rotating shaft moves synchronously, so the rotating shaft can rotate while making circumferential movement.

[0064] During the rotation of the worm 34, the worm wheel 31 is engaged with the worm 34, thereby rotating the worm wheel 31; during the rotation of the worm wheel 31, the short shaft 29 rotates synchronously; during the rotation of the short shaft 29, the cam 30 rotates synchronously; during the rotation of the cam 30, when the raised portion of the cam 30 abuts against the hollow block 32, the second spring 33 is compressed during the vertical downward movement of the hollow block 32, and when the raised portion of the cam 30 no longer abuts against the hollow block 32, the hollow block 32 is reset under the action of the second spring 33, and the hollow block 32 moves vertically upward; therefore, the hollow block 32 can perform vertical reciprocating motion.

[0065] The hollow block 32 moves vertically downward, the linkage block 13 moves synchronously, and the third spring 35 is compressed; during the vertical upward movement of the hollow block 32, the linkage block 13 is reset under the action of the third spring 35, and the linkage block 13 moves vertically upward; therefore, the linkage block 13 can perform vertical reciprocating motion.

[0066] During the vertical reciprocating motion of the linkage block 13, the rack 27 moves synchronously; during the vertical downward motion of the rack 27, since the rack 27 is meshed with the second gear 26, the second gear 26 can rotate forward; similarly, during the vertical upward motion of the rack 27, the second gear 26 rotates reversely; therefore, the second gear 26 can rotate forward and reversely; during the rotation of the second gear 26, the rotating shaft 8 rotates synchronously.

[0067] During the rotation of the shaft, the fixed block 7 moves synchronously; during the movement of the fixed block 7, the rotating shaft 8 moves synchronously; therefore, while the rotating shaft 8 makes circumferential motion, the rotating shaft 8 can also rotate; during the movement of the rotating shaft 8, the elastic disk 9 moves synchronously; during the movement of the elastic disk 9, the elastic block 11 moves synchronously.

[0068] Through the above movement, since the elastic block 11 is in contact with the inner wall of the cylindrical tube 1, the circumferential movement of the elastic block 11 can clean the sticky substances on the inner wall of the cylindrical tube 1 in the circumferential direction, thereby making the sticky substances at any position on the inner wall of the cylindrical tube 1 in the circumferential direction be cleaned under the action of the elastic block 11; and, since the elastic block 11 can also rotate while making the circumferential movement, the elastic block 11 has a certain force, and the elastic block 11 can clean the sticky substances adhering to the inner wall of the cylindrical tube 1 more fully and completely, thereby ensuring that the sticky substances on the inner wall of the cylindrical tube 1 are thoroughly cleaned; that is, through the movement of the elastic block 11, the sticky substances adhering to the inner wall of the cylindrical tube 1 can be cleaned, so that the sticky substances can be mixed into the mixture again for stirring, thereby improving the utilization rate of the mixture, enhancing the stirring effect, and improving the stirring efficiency.

[0069] During the movement of the rotating shaft 8, the rotating shaft 8 can break up and stir the mixture in the circumferential direction of the cylindrical barrel 1 when it revolves, so that the mixture in the circumferential direction of the cylindrical barrel 1 has fluidity, and the mixture in the circumferential direction of the cylindrical barrel 1 can continuously change its position, thereby increasing the movement path of the mixture, accelerating the speed of fully mixing the mixture, thereby shortening the mixing time and improving the mixing efficiency.

[0070] During the rotation of the rotating shaft 8, the stirring blade 42 moves synchronously; when the stirring blade 42 rotates, for viscous liquids such as cement, mortar, asphalt and other mixtures, which have poor fluidity, the stirring blade 42 can continuously change the position of the mixture on the upper part of the rotating shaft 8 and the mixture on the lower part of the rotating shaft 8 when it moves in the circumferential direction of the cylindrical tube 1, thereby expanding the range of the mixture being stirred. Therefore, the rotation of the stirring blade 42 can stir the mixture at any position in the height direction of the cylindrical tube 1, ensuring that the mixture is stirred more completely and evenly.

[0071] In summary, under the joint action of the rotating shaft 8 and the stirring blades 42, the mixed material in the cylindrical barrel 1 can be fully and evenly stirred, that is, the mixed material is mixed more completely and thoroughly, and the quality of the mixed material after stirring is fully guaranteed.

[0072] During the circumferential motion of the rotating shaft, the disc 12 moves synchronously; during the motion of the disc 12, the linkage block 13 moves synchronously; therefore, while the linkage block 13 makes circumferential motion, the linkage block 13 can also make vertical reciprocating motion; during the motion of the linkage block 13, the side block 14 moves synchronously; during the motion of the side block 14, the throwing block 15 moves synchronously; during the vertical reciprocating motion of the throwing block 15, the throwing block 15 can drive the mixture to continuously make vertical reciprocating motion, thereby changing the position of the mixture in the height direction in the cylindrical barrel 1, and realizing the exchange of positions of the mixture above the throwing block 15 and the mixture below the throwing block 15, thereby ensuring that the mixture can be mixed more fully and more completely; and, since the throwing block 15 can also make circumferential motion, thereby expanding the scope of action of the throwing block 15, the mixture in the cylindrical barrel 1 can all exchange positions in the height direction, thereby promoting more uniform mixing of the mixture, further ensuring more comprehensive mixing of the mixture, enhancing the stirring effect, and improving the stirring efficiency.

[0073] In summary, through the circumferential movement and vertical movement of the side block 14, the range of action of the throwing block 15 is expanded and the effect of the throwing block 15 is enhanced, that is, the throwing block 15 can drive the mixture in the cylindrical barrel 1 to interact with each other comprehensively and fully, thereby ensuring the quality after mixing and enhancing the use effect of the mixture.

[0074] During the circumferential movement of the side block 14, when the linkage block 13 moves vertically downward, the linkage rod 37 moves synchronously; during the vertical downward movement of the linkage rod 37, the linkage rod 37 is subjected to the reaction force of the inner wall of the cylindrical tube 1, thereby causing the linkage rod 37 to move vertically upward relative to the vertical groove, and the fourth spring 38 is stretched; during the vertical upward movement of the linkage rod 37, the arcuate protrusion 36 moves synchronously; during the movement of the arcuate protrusion 36, since the spherical wedge block 39 is against the arcuate protrusion 36, the spherical wedge block 39 moves to a position close to the inner wall of the cylindrical tube 1 under the drive of the arcuate protrusion 36, the fifth spring 40 is compressed, and the slider 16 moves synchronously; similarly, during the vertical upward movement of the linkage block 13, the linkage rod 37 is reset under the action of the fourth spring 38, and the spherical wedge block 39 is reset under the action of the fifth spring 40; therefore, the slider 16 can make reciprocating motion along the length direction of the side hole.

[0075] The slider 16 reciprocates along the length direction of the side block 14; during the movement of the slider 16, the impact block 17 moves synchronously; during the movement of the impact block 17, it can impact the viscous material on the circumferential direction of the inner wall of the cylindrical tube 1, so that the viscous material at any position on the circumferential direction of the inner wall of the cylindrical tube 1 is impacted by the impact block 17; similarly, when the side block 14 moves vertically, the viscous material at any position on the height direction of the inner wall of the cylindrical tube 1 is also impacted by the impact block 17.

[0076] Through the above-mentioned movement, during the impact of the impact block 17, on the one hand, the amount of viscous material adhering to the inner wall of the cylindrical tube 1 can be reduced, and on the other hand, the adhesion force of the viscous material adhering to the inner wall of the cylindrical tube 1 can be weakened, that is, the viscous material becomes loose; the loosened viscous material can be mixed into the mixture again under the action of the elastic block 11, thereby reducing the probability of the feed port being blocked, reducing the amount of the mixture adhering to the inner wall of the cylindrical tube 1, improving the utilization rate of the mixture, ensuring that the mixture can be fully collected, and improving the subsequent construction effect of the mixture.

[0077] In summary, under the combined action of the circumferential movement and the vertical movement of the impact block 17, the viscous material on the inner wall of the cylindrical barrel 1 can be comprehensively and thoroughly processed, that is, the viscous material on the inner wall of the cylindrical barrel 1 can be acted upon by the impact block 17, so that the viscous material can be mixed into the mixture again to complete the mixing operation.

[0078] During the movement of the impact block 17, the conical block 18 moves synchronously; during the movement of the conical block 18, the force exerted by the conical block 18 on the viscous material is greater than that of the impact block 17, and the impact effect is better. On the one hand, it can reduce the amount of viscous materials with strong viscosity adhering to the inner wall of the cylindrical tube 1, and on the other hand, it can further weaken the adhesion of the viscous materials to the inner wall of the cylindrical tube 1, that is, the viscous materials become loose; the loosened viscous materials are easier to clean up under the action of the elastic block 11, which further improves the working efficiency of the elastic block 11.

[0079] The conical block 18 is arranged in the auxiliary hole so that when the impact block 17 is subjected to the reaction force of the inner wall of the cylindrical tube 1, the impact block 17 moves in the opposite direction along the length direction of the side block 14. On the one hand, it can promote the stability of the movement of the impact block 17, and on the other hand, it can ensure that the impact block 17 will not break due to excessive deformation, that is, the impact block 17 is reinforced.

[0080] Since the conical block 18 can also make circumferential motion, the conical block 18 can impact the sticky substances on the circumferential direction of the inner wall of the cylindrical tube 1 when it moves circumferentially. Therefore, the sticky substances at any position on the circumferential direction of the inner wall of the cylindrical tube 1 are all impacted by the conical block 18; similarly, when the conical block 18 moves vertically, the sticky substances at any position on the height direction of the inner wall of the cylindrical tube 1 are also impacted by the conical block 18.

[0081] In summary, through the circumferential movement and vertical movement of the conical block 18, the viscous material on the inner wall of the cylindrical barrel 1 can be comprehensively and thoroughly processed, that is, the viscous material on the inner wall of the cylindrical barrel 1 can be impacted by the conical block 18, further ensuring that the viscous material can be completely mixed into the mixture, thereby improving the utilization rate of the mixture.

[0082] During the circumferential motion of the rotating shaft, the auxiliary block 19 moves synchronously; during the rotation of the auxiliary block 19, the auxiliary block 19 has a greater force than the rotating shaft 8 and a better stirring effect, so that when the auxiliary block 19 further stirs the mixture in the cylindrical barrel 1, the auxiliary block 19 can break up the clumped mixture; after the mixture is broken up, the mixture can be more fully and comprehensively stirred and mixed under the joint action of the throwing block 15 and the stirring blade 42, thereby improving the stirring efficiency.

[0083] During the vertical reciprocating motion of the edge block 14, the first wedge block 20 moves synchronously; during the movement of the first wedge block 20, since the second wedge block 21 is located on the movement trajectory of the first wedge block 20, when the first wedge block 20 and the second wedge block 21 are in contact with each other, the first wedge block 20 can drive the two second wedge blocks 21 to move away from each other along the width direction of the auxiliary block 19, and the first spring 23 is compressed. When the first wedge block 20 no longer contacts the second wedge block 21, the second wedge block 21 is reset under the action of the first spring 23, and the two second wedge blocks 21 approach each other along the width direction of the auxiliary block 19; therefore, the two second wedge blocks 21 can approach or move away from each other; during the movement of the second wedge block 21, the cutting knife 22 moves synchronously.

[0084] During the movement of the cutting blade 22, the cutting blade 22 has a certain force. The cutting blade 22 can cut and break up the relatively viscous and clumped mixture, so that the viscous mixture is dispersed, and then mixed again with other mixtures in the cylindrical tube 1, thereby enhancing the stirring effect of the mixture and further ensuring the quality of the mixed mixture; and, since the cutting blade 22 can also make circumferential motion, the action range of the cutting blade 22 is expanded, the effect of the cutting blade 22 is enhanced, and it is ensured that the viscous mixture in the cylindrical tube 1 can be dispersed under the action of the cutting blade 22, that is, the mixture is mixed more evenly and thoroughly.

[0085] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
