Description

Technical Field

[0001] The invention relates to the field of stirring and mixing, and in particular to a curing agent stirring device for asphalt road maintenance. Background Art

[0002] A stirring device is a device used to mix, stir and evenly disperse a variety of materials. It is widely used in chemical, pharmaceutical, food, building materials and other industries.

[0003] For example, road curing agents often use stirring devices to mix various raw materials during the production process. Curing agents are usually used to maintain the surface layer of asphalt pavement to extend the service life of the road and maintain the performance of the road. In order to ensure the effect of curing agents during construction, uniform stirring is necessary.

[0004] The principle of the stirring device to mix materials evenly is to promote mixing in the form of shear force mixing and rotation to promote material flow circulation. The shear force can cause turbulence near the blades and improve the degree of mixing near the stirring blades. Due to the high viscosity of the curing agent, it is difficult for ordinary stirring devices to produce effective mixing for viscous materials due to shear force. Therefore, in general, viscous materials use screw-type stirring rods to improve the circulation of materials. When stirring the curing agent, since the viscosity of the material changes during the process of adding the material, it is difficult for ordinary stirring devices to fully stir the curing agent. If the stirring is not sufficient and the materials are not mixed evenly, the quality of the curing agent will be reduced. Low-quality curing agents will not be able to effectively fill road cracks or bond to road surface materials, resulting in premature aging and damage to the road surface, or even more serious safety hazards. Summary of the invention

[0005] Based on this, it is necessary to provide a curing agent stirring device for asphalt road maintenance to address the problem that the current stirring device has poor mixing effect when stirring materials with high viscosity, resulting in low quality of the curing agent.

[0010] The auxiliary stirring mechanism comprises a plurality of stirring plates, which are evenly distributed on the periphery of the auger, are connected to the stirring auger, and rotate synchronously with the stirring auger;

[0011] The plurality of stirring plates are arranged such that, at the initial stage when the material enters the cylinder, the plurality of stirring plates are parallel to each other and to the axis of the stirring auger, and at the later stage when the material enters the cylinder, the plurality of stirring plates are tilted synchronously;

[0012] A limit assembly is used to limit the degree of inclination of the plurality of stirring plates.

[0013] Furthermore, the auxiliary stirring mechanism also includes a first connecting rod, a second connecting rod and a connecting ring sleeve, the connecting ring sleeve is sleeved on the upper end of the rotating shaft of the stirring auger, an elastic member is arranged between the upper end surface of the connecting ring sleeve and the rotating shaft of the stirring auger, one end of the first connecting rod is hinged on the outer periphery of the connecting ring sleeve, the other end of the first connecting rod is ball-connected to the upper end of the stirring plate, one end of the second connecting rod is hinged on the lower end of the rotating shaft of the stirring auger, and the other end of the second connecting rod is ball-connected to the lower end of the stirring plate.

[0015] The articulated ball on the stirring plate is a semicircular sphere. When the articulated ball is located in the ball connection groove, the spherical surface of the articulated ball contacts the inner side of the ball connection groove, the plane of the articulated ball contacts the limit ball, and the plane of the articulated ball contacts the surface of the conical tip of the limit block to limit the stirring plate from continuing to tilt.

[0016] Furthermore, the maximum inclination degree of the stirring plate is positively correlated with the taper size of the conical tip of the limiting block.

[0017] Furthermore, a plurality of telescopic rods are provided at the upper end of the rotating shaft of the stirring auger, and the plurality of telescopic rods are distributed along the circumference of the rotating shaft of the stirring auger, one end of the plurality of telescopic rods is connected to the rotating shaft, and the other end of the plurality of telescopic rods is fixed to the elastic member, and the telescopic rods are extended and retracted to push and pull the elastic member, and the force of the elastic member acts on the connecting ring sleeve;

[0018] The plurality of telescopic rods are configured such that when the telescopic rods are shortened, the connecting ring sleeve is pulled to move along the upper end of the rotating shaft to pull the upper ends of the stirring plates to gather toward the middle, and the telescopic rods are reset when they are extended.

[0019] Furthermore, a driving assembly is also provided on the cylinder, and the driving assembly is used to drive the stirring auger to rotate.

[0020] Furthermore, the driving assembly includes a driving motor and a mounting plate, wherein the mounting plate is fixedly disposed on the cylinder, the driving motor is fixed by the mounting plate, and the transmission shaft of the driving motor is coaxial with and fixedly connected to the rotating shaft of the stirring auger.

At this time, the stirring plate only has a stirring function but not a conveying function, while the stirring auger only has a conveying function, thereby making up for the stirring function of the stirring auger, so that the stirring effect of the curing agent material in the cylinder is better. When there is a lot of curing agent material in the cylinder, the stirring components in the traditional stirring equipment are all subject to greater resistance, and the stirring effect is greatly reduced.

[0043] Refer to the following Figure 1-Figure 10 To describe a curing agent stirring device for asphalt road maintenance provided by the present invention.

[0044] A curing agent stirring device for asphalt road maintenance is suitable for mixing and stirring curing agents, comprising a cylinder 100, the cylinder 100 is used to accommodate curing agent materials, a feed port 110 is provided at the upper end of the cylinder 100, the curing agent materials are gradually added into the cylinder 100 from the feed port 110, a stirring auger 200 is provided inside the cylinder 100, the stirring auger 200 is coaxially arranged with the cylinder 100, the stirring auger 200 can stir and mix the curing agent materials inside the cylinder 100 when rotating, a discharge port 120 is provided at the bottom end of the cylinder 100, and the stirred and mixed curing agent materials are discharged from the discharge port 120.

[0045] An auxiliary stirring mechanism is also provided inside the cylinder 100, which is used to assist the stirring auger 200 in stirring and curing materials to improve the stirring and mixing effect. The auxiliary stirring mechanism includes a plurality of stirring plates 210, which are evenly distributed on the circumference of the stirring auger 200, and are connected to the stirring auger 200. When the stirring auger 200 rotates, the plurality of stirring plates 210 are driven to rotate together. The plurality of stirring plates 210 are specifically located on the periphery of the stirring auger 200 and are in sliding contact with the inner wall of the cylinder 100.

[0046] The plurality of stirring plates 210 are configured such that, in the initial state, the curing agent material has just entered the cylinder 100, and there is less curing agent material in the cylinder 100. The plurality of stirring plates 210 are in a state parallel to each other and to the axis of the stirring auger 200. The stirring auger 200 rotates to convey (conveying means conveying the curing agent from the bottom to the upper end or from the upper end to the lower end, so that the curing agent material surges in the cylinder 100 and has a certain mixing effect) the curing agent material, and has a certain stirring and mixing effect. At the same time, the stirring plates 210 are parallel to each other relative to the rotating shaft 201 of the stirring auger 200, and the plurality of stirring plates 210 revolve around the axis of the stirring auger 200, so that the stirring plates 210 can fully stir the curing agent material. Function: the stirring auger 200 rotates to play a certain stirring role, and the stirring plate 210 can also play a conveying role, thereby improving the stirring effect of the curing agent material; as the amount of the curing agent material inside the cylinder 100 increases, due to the high viscosity of the curing agent material, the stirring plate 210 is tilted, so that the stirring plate 210 also has a partial conveying capacity, that is, the stirring plate 210 can not only stir the curing agent material when rotating, but also push the curing agent material to move upward or downward (upward or downward depends on the rotation direction of the stirring plate 210), thereby assisting the stirring auger 200 to convey the curing agent material, thereby increasing the frequency of the curing agent material surging in the cylinder 100, and also improving the mixing uniformity of the curing agent material.

[0047] It can be understood that by changing the posture of the stirring plate 210, the stirring plate 210 is initially in a vertical state (the vertical state refers to the stirring plate 210 being parallel to the axis of the stirring auger 200). At this time, the stirring plate 210 only has a stirring function but does not have a conveying function, thereby making up for the defect that the stirring auger 200 only has a conveying function but not a stirring function, so that the stirring effect of the curing agent material in the cylinder 100 is better. When there is a lot of curing agent material in the cylinder 100, the stirring components in the traditional stirring equipment are all subject to greater resistance, and the stirring effect is greatly reduced. The present invention adopts a combination of the stirring auger 200 and the stirring plate 210, so that in the curing agent material with higher viscosity, the stirring function is converted into conveying, so that the frequency of the curing agent material with higher viscosity surging in the cylinder 100 is increased, and the mixing uniformity is improved, that is, the stirring plate 210 has both stirring and conveying functions after being tilted, so that the curing agent material in the cylinder 100 is evenly mixed.

[0048] A limit assembly is also provided in the cylinder 100, and the limit assembly is used to limit the inclination degree of the stirring plate 210. The inclination degree of the stirring plate 210 can be adjusted according to different types or brands of curing agent materials to prevent the stirring plate 210 from tilting too little or too much, thereby reducing the stirring and mixing effect of the curing agent material in the cylinder 100.

[0049] Specifically, the auxiliary stirring mechanism also includes a first connecting rod 220, a second connecting rod 230 and a connecting ring sleeve 250. The connecting ring sleeve 250 is rotatably connected to the upper end of the rotating shaft 201 of the stirring auger 200. An elastic member 260 is arranged on the upper end surface of the connecting ring sleeve 250. The elastic member 260 is also sleeved on the rotating shaft 201 of the stirring auger 200. One end of the elastic member 260 is connected to the rotating shaft 201 of the stirring auger 200, and the other end of the elastic member 260 is fixedly connected to the connecting ring sleeve 250, so that the connecting ring sleeve 250 has the function of maintaining or restoring the initial position on the rotating shaft 201 of the stirring auger 200. There are a plurality of first connecting rods 220, which are evenly distributed on the outer periphery of the connecting ring sleeve 250, and are arranged radially along the connecting ring sleeve 250, one end of a plurality of first connecting rods 220 is hinged to the connecting ring sleeve 250, and the other ends of a plurality of first connecting rods 220 are respectively ball-jointed with the upper ends of a plurality of stirring plates 210, and a plurality of second connecting rods 230 are evenly distributed on the outer periphery of the lower end of the rotating shaft 201 of the stirring auger 200, and are arranged radially along the stirring auger 200, one end of a plurality of second connecting rods 230 is hinged to the lower end of the rotating shaft 201 of the stirring auger 200, and the other ends of a plurality of second connecting rods 230 are respectively ball-jointed with the lower ends of a plurality of stirring plates 210, forming Figure 3 In the state shown, the stirring plate 210 is slidably fitted on the inner wall of the cylinder 100 , and the first connecting rod 220 and the second connecting rod 230 are respectively connected to the stirring plate 210 .

[0050] When the stirring auger 200 rotates, the stirring plate 210 is driven to rotate by the second connecting rod 230 hinged at the lower end. When the curing agent material in the cylinder 100 is less, the curing agent material has a smaller force on the stirring plate 210, so that the elastic member 260 maintains its original state, so that the connecting ring sleeve 250 does not move axially relative to the stirring auger 200, so that the connecting ring sleeve 250 can rotate synchronously with the stirring auger 200, and the stirring plate 210 maintains its initial vertical state. When the curing agent material in the cylinder 100 increases more, the viscosity increases, and the force on the stirring plate 210 gradually increases. When the force exceeds the force of the elastic member 260, the stirring plate 210 no longer maintains a vertical state, but gradually tilts, thereby stretching the elastic member 260, so that the connecting ring sleeve 250 rotates relative to the stirring auger 200, forming a Fig. 9 The more curing agent material there is in the cylinder 100, the greater the force applied to the stirring plate 210, and the degree of inclination of the stirring plate 210 gradually increases until it reaches the degree of inclination limited by the limit assembly and stops inclining further.

[0051] Specifically, the limiting assembly includes a limiting block 300 and a limiting ball 320. The limiting block 300 is arranged at the ball connection position between the first connecting rod 220 and the stirring plate 210. The first connecting rod 220 is provided with a ball connection groove 240, and the limiting block 300 is arranged in the ball connection groove 240. The limiting ball 320 is arranged on the limiting block 300. Figure 8 As shown, a hinge ball 211 is provided at the upper end of the stirring plate 210, and the shape of the hinge ball 211 is a semi-sphere, and the semi-sphere has a semi-spherical surface 212 and a plane 213. The hinge ball 211 on the stirring plate 210 is located in the ball connection groove 240 on the first connecting rod 220, and the semi-spherical surface 212 of the hinge ball 211 contacts the inner side of the ball connection groove 240, and the plane 213 of the hinge ball 211 is ball-connected with the limiting ball 320 on the limiting block 300, that is, a ball groove 214 is opened on the plane 213 of the hinge ball 211 (the ball groove 214 is specifically located at the center of the hinge ball 211), and the limiting ball 320 is ball-connected in the ball groove 214, so that the first connecting rod 220 and the stirring plate 210 are ball-connected.

[0052] It should be noted that, in the embodiment of the present invention, the ball joint structure between the second connecting rod 230 and the lower end of the stirring plate 210 is the same as the above-mentioned structure, and the limit block 300 has a conical tip 310, and the limit ball 320 is fixedly arranged at the tip of the conical tip 310. When the stirring plate 210 is tilted, the plane 213 of the hinged ball 211 will gradually approach the surface of the conical tip 310. When the plane 213 of the hinged ball 211 contacts the surface of the conical tip 310 of the limit block 300, it cannot continue to tilt, thereby limiting the stirring plate 210 from continuing to tilt, so that the stirring plate 210 has a maximum degree of inclination.

[0053] At the same time, the maximum inclination degree of the stirring plate 210 can be changed by changing the taper of the conical tip 310 on the limit block 300, that is, the maximum inclination degree of the stirring plate 210 is positively correlated with the taper of the conical tip 310 of the limit block 300. When the taper of the conical tip 310 on the limit block is larger, the conical tip 310 is sharper, and the side inclination angle of the conical tip 310 is larger, so that the stirring plate 210 is limited by the limit block 300 only after it is tilted to a greater extent, thereby increasing the maximum inclination degree of the stirring plate 210; when the taper of the conical tip 310 on the limit block 300 is smaller, the side of the conical tip 310 is smoother, and the side inclination angle is smaller, and the stirring plate 210 is limited after it is tilted to a smaller extent, thereby reducing the maximum inclination degree of the stirring plate 210.

[0054] It can be understood that the degree of inclination of the stirring plate 210 is adjusted by changing the taper of the conical tip 310 on the limit block 300 to achieve the effect of regulating the degree of stirring and mixing of the curing agent material, that is, when the inclination of the stirring plate 210 is greater, its stirring effect is weaker than the conveying effect, and when the inclination of the stirring plate 210 is smaller, its stirring effect is stronger than the conveying effect. Based on this, the user can replace different limit blocks 300 according to actual conditions.

[0055] In a further embodiment, the present invention provides a first connecting rod 220, a second connecting rod 230 and a connecting ring sleeve 250, and an elastic member 260 is provided on the connecting ring sleeve 250. When the mixed curing agent materials in the cylinder 100 are all discharged from the cylinder 100, the stirring plate 210 returns to a vertical state, and the stirring plate 210 slides against the inner wall of the cylinder 100, and continues to drive the stirring auger 200 to rotate so that the stirring plate 210 scrapes the residual curing agent materials on the inner wall of the cylinder 100. If there are depressions or protrusions on the same vertical plane 213 on the inner wall of the cylinder 100, the stirring plate 210 can always fit the inner wall of the cylinder 100 under the action of the elastic member 260, thereby cleaning the residual curing agent materials remaining in the depressions or protrusions.

[0056] In a further embodiment, a plurality of telescopic rods 270 are arranged at the upper end of the rotating shaft 201 of the stirring auger 200, and the plurality of telescopic rods 270 are evenly distributed on the outer periphery of the rotating shaft 201 of the stirring auger 200. The axes of the plurality of telescopic rods 270 are parallel to the axis of the stirring auger 200, and one end of the plurality of telescopic rods 270 is connected to the upper end of the rotating shaft 201 of the stirring auger 200. Specifically, a rotating ring sleeve 290 is sleeved on the rotating shaft 201 of the stirring auger 200, and the rotating ring sleeve 290 can only rotate relative to the stirring auger 200 but cannot rotate relative to the stirring auger 200. The stirring auger 200 moves axially, and one end of a plurality of telescopic rods 270 is fixedly connected to the rotating ring sleeve 290, and the other end of the plurality of telescopic rods 270 is connected to the elastic member 260. For the convenience of connection, a sliding ring 280 is provided between the elastic member 260 and the plurality of telescopic rods 270. The sliding ring 280 is sleeved on the rotating shaft 201 of the stirring auger 200. When the telescopic rod 270 is extended or shortened, the elastic member 260 can be pushed and pulled, and the connecting ring sleeve 250 is pushed or pulled by the elastic member 260 to change the state of the stirring plate 210.

[0057] It should be noted that as the stirring and mixing time inside the cylinder 100 increases, most of the curing agent materials in the cylinder 100 form a relatively stable state under the conveying action of the stirring auger 200. At this time, the stirring and mixing effect of the curing agent materials will be weakened. Therefore, it is necessary to break the stable state of the curing agent materials to improve the stirring and mixing effect of the curing agent materials. At this time, the lengths of the several telescopic rods 270 are shortened, and the several telescopic rods 270 pull the elastic member 260 to move upward, and the elastic member 260 then pulls the connecting ring sleeve 250 to move upward, and the connecting ring sleeve 250 pulls the upper ends of the several stirring plates 210 through the first connecting rod 220, so that the upper ends of the stirring plates 210 move toward the axis direction of the stirring auger 200, that is, the upper ends of the several stirring plates 210 gather toward the middle, so that the stirring plates 210 are further tilted toward the middle on the basis of the original tilt. Fig.10 As shown, the upper end of the stirring plate 210 is close to the stirring auger 200, and the lower end of the stirring plate 210 is close to the edge of the cylinder 100, so that the stirring plate 210 can break the stable state in the cylinder 100. After the upper end of the stirring plate 210 is tilted inward, it can promote the mixing of the curing agent material near the side wall of the cylinder 100 and the stirring auger 200, which is equivalent to the stirring plate 210 changing the direction of the surging flow of the curing agent material in the cylinder 100, further improving the mixing uniformity of the curing agent material, and the telescopic rod 270 is reset when extended to restore the original state.

[0058] More specifically, the length of the telescopic rod 270 can be changed by setting an interval time so as to constantly change the direction of the surging flow of the curing agent material in the cylinder 100.

[0059] In a further embodiment, a driving assembly is further provided on the cylinder 100 , and the driving assembly is used to drive the stirring auger 200 to rotate. The driving assembly is used to drive the stirring auger 200 to rotate.

[0060] Specifically, the driving assembly includes a driving motor 150 and a mounting plate 140. A cover plate 130 is provided at the upper end of the cylinder 100. The mounting plate 140 is fixedly mounted on the cover plate 130, and the driving motor 150 is fixedly mounted on the cover plate 130 through the mounting plate 140. The transmission shaft of the driving motor 150 is coaxial with and fixedly connected to the rotating shaft 201 of the stirring auger 200. When the driving motor 150 rotates, it drives the stirring auger 200 to rotate to stir and transport the curing agent material in the cylinder 100.

[0061] In a further embodiment, the number of the stirring plates 210 is at least four, and may also be five, six, etc. The number of the stirring plates 210 may be adjusted according to actual needs. In this embodiment, only four are taken as an example.

[0062] Specifically, a support leg 160 is disposed at the bottom of the cylinder 100 , and the support leg 160 is used to support the cylinder 100 , so that the cylinder 100 is more stable.

[0063] More specifically, the discharge port 120 at the bottom of the cylinder 100 is provided with a discharge pipe 121 , and the length of the discharge pipe 121 is not limited, so as to facilitate the discharge of the evenly mixed curing agent material.

[0064] The specific working process of the curing agent stirring device for asphalt road maintenance provided by the present invention is described in combination with the above embodiments:

[0065] start up:

[0066] Start the drive motor 150, the drive motor 150 rotates to drive the stirring auger 200 to rotate, the stirring auger 200 rotates to drive several second connecting rods 230 to rotate synchronously, the stirring plate 210 slides against the inner wall of the cylinder 100, and an elastic member 260 is provided on the connecting ring sleeve 250. When the connecting ring sleeve 250 does not move axially relative to the rotating shaft 201 of the stirring auger 200, the second connecting rod 230 drives the stirring plate 210 to rotate, so that the connecting ring sleeve 250 and the stirring auger 200 rotate synchronously, so that the stirring plates 210 are initially parallel to each other and parallel to the axis of the stirring auger 200.

[0067] mix:

[0068] The curing agent material is added into the barrel 100 through the feed port 110. When the curing agent material is first added, there is less curing agent material in the barrel 100, and the force exerted by the curing agent material on the stirring plate 210 when the stirring plate 210 is in a vertical state and rotates is smaller. At this time, the stirring effect of the curing agent material is better. As more curing agent material is added into the barrel 100, due to the greater viscosity of the curing agent material, the force exerted by more curing agent material on the stirring plate 210 increases. When the force increases to push the stirring plate 210 to tilt, the stirring plate 210 pulls the first connecting rod 220, and the first connecting rod 220 pulls the elastic member 260 to extend. As the stirring plate 210 gradually tilts, the stirring effect of the stirring plate 210 weakens, while the conveying effect strengthens, so that more curing agent material in the barrel 100 surges in the barrel 100 more frequently, so that more curing agent material in the barrel 100 can also be mixed evenly.

[0069] After mixing for a period of time, the telescopic rod 270 on the rotating shaft 201 of the stirring auger 200 is shortened, the telescopic rod 270 pulls the elastic member 260, the elastic member 260 pulls the connecting ring sleeve 250, the connecting ring sleeve 250 pulls the first connecting rod 220, and the first connecting rod 220 pulls the upper end of the stirring plate 210 toward the stirring auger 200, so that the stirring plate 210 is tilted toward the stirring auger 200 on the basis of the original inclination of the stirring plate 210, thereby changing the surging flow direction of the curing agent material in the cylinder 100, thereby breaking the stable state in the cylinder 100, and further evenly mixing the curing agent material in the cylinder 100.

[0070] Nesting:

[0071] The curing agent material that is evenly mixed after stirring enters the discharge pipe 121 through the discharge port 120 , and the user simply places the pipe opening of the discharge pipe 121 at a designated position.

[0072] clean:

[0073] When all the curing agent materials in the cylinder 100 are discharged, the stirring plate 210 is no longer affected by the curing agent materials, and the elastic member 260 is reset to pull the stirring plate 210 back to a vertical state. The stirring plate 210 slides in contact with the inner wall of the cylinder 100 to scrape off the curing agent materials remaining on the inner wall to prevent the curing agent materials from adhering to the inner wall of the cylinder 100.

[0074] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
