Description

Technical Field

[0001] The present application relates to the technical field of engineering material detection, and in particular to an accelerated polishing device. Background Art

[0002] The accelerated polishing equipment is used to simulate the polishing effect of automobile tires on highway asphalt pavement indoors. The anti-wear performance of the aggregate is evaluated by accelerating the polishing of the aggregate used in the pavement and measuring the polishing value of the aggregate.

[0003] The accelerated polishing equipment usually includes a machine body, and a polishing device and a sand sliding device installed on the machine body. The test piece is installed on the polishing device. The sand sliding device is used to transport sand to the test piece of the polishing device. The polishing device has a feed port for sand to enter. Friction is generated between the sand and the rotating test piece to simulate the wear of the actual road surface in use.

[0004] The existing sand chute device includes a hopper and a conveyor belt, one end of the conveyor belt is opposite to the discharge port of the hopper, and the other end of the conveyor belt is opposite to the feed port of the polishing device, so as to convey the sand material to the polishing device. However, when conveying sand with a larger particle size, the sand is easy to be blocked at the discharge port of the hopper, affecting the conveying of the sand material, which has an adverse effect on the test. Utility Model Content

[0005] In order to reduce the impact of adverse factors in the test, the present application provides an accelerated polishing device.

[0006] The present application provides an accelerated polishing device, which adopts the following technical solution:

[0007] An accelerated polishing device comprises a machine body, a sand-sliding device and a polishing device, wherein the sand-sliding device and the polishing device are both mounted on the machine body, the polishing device has a feed channel, and the sand-sliding device comprises

[0008] A mounting frame, mounted on the machine body;

[0009] A conveyor belt is conveyed on the mounting frame, one end of which is opposite to the feed channel;

[0010] A storage hopper, mounted on the mounting frame, having a discharge port opposite to the conveyor belt;

[0011] a disturbing member rotating in the storage hopper; and

[0012] The driving mechanism cooperates with the conveyor belt and the disturbance member to drive the conveyor belt to transport and the disturbance member to rotate at the same time.

[0013] By adopting the above technical solution, the driving mechanism drives the conveyor belt to transmit and drives the disturbance member to rotate at the same time, so that the disturbance member stirs the sand material in the storage hopper, so that the sand material can be more active during discharge, so that the sand material is not easy to be blocked at the discharge port of the storage hopper, thereby reducing the impact of adverse factors in the test.

[0014] Optionally, the conveyor belt is inclined upward in a direction close to the feed channel.

[0015] By adopting the above technical solution, when the feeding stops, the conveyor belt tends to tilt upward in the direction close to the feed channel, which can make the sand on the conveyor belt tend to move away from the feed channel, so that the sand is not easy to fall excessively.

[0016] Optionally, a feeding gap is formed between a side of the storage hopper close to the feeding channel and the feeding belt, and a side of the storage hopper away from the feeding channel abuts against the feeding belt.

[0017] By adopting the above technical solution, the sand material is completely moved out of the storage hopper from the feeding gap, and the storage hopper is in contact with the conveyor belt on the side away from the feeding channel, so that the sand material is not easily moved out from the storage hopper on the side away from the conveyor belt, thereby improving the stability of the sand material.

[0018] Optionally, the mounting frame includes

[0019] A base, mounted on the body;

[0020] A bearing seat, used for mounting the conveyor belt and the storage hopper;

[0021] an adjusting member connected to the bearing seat and rotatable on the base; and

[0022] The locking member is threadedly moved on the base toward or away from the adjusting member, and is used to abut against the adjusting member to limit the position of the adjusting member.

[0023] By adopting the above technical solution, when the adjusting member rotates relative to the base, it can drive the conveyor belt and the storage hopper to move together, so that the conveyor belt and the storage hopper can be driven to shake by reciprocatingly rotating the adjusting member, so as to further improve the smoothness of sand material discharge.

[0024] Optionally, the adjusting member is detachably connected to the base.

[0025] By adopting the above technical solution, the adjusting member is detachably connected to the base, so that the adjusting member, the bearing seat and the components on the bearing seat can be removed for maintenance.

[0026] Optionally, the adjusting member is provided with a travel groove along the circumference of its own rotation axis for the locking member to abut against.

[0027] By adopting the above technical solution, the travel groove can guide the relative matching position between the locking member and the adjusting member, so as to improve the stability of the adjusting member.

[0028] Optionally, the storage hopper gradually expands in a direction away from the conveyor belt.

[0029] By adopting the above technical solution, the storage hopper that expands away from the conveyor belt can facilitate the feeding of sand material.

[0030] Optionally, the storage hopper is detachably connected to the mounting frame.

[0031] By adopting the above technical solution, the storage hopper is detachably connected so that the storage hopper can be removed for cleaning.

[0032] In summary, the present application includes at least one of the following beneficial effects:

[0033] 1. The conveyor belt is driven by the driving mechanism to transmit and the disturbance piece is driven to rotate at the same time, so as to improve the smoothness of the conveyor belt transmitting sand material and the material discharge from the storage hopper. The conveyor belt transmission and the rotation of the disturbance piece are synchronously controlled, which is conducive to simplifying the operation process and improving the convenience of operation.

[0034] 2. The adjusting member is rotated relative to the base to drive the bearing seat and the storage hopper to shake, and the sand in the storage hopper is moved, so as to assist in improving the smoothness of the sand output from the storage hopper to the conveyor belt when the sand is blocked.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-3 This application is described in further detail.

[0040] The present application embodiment discloses an accelerated polishing device. Figure 1 The accelerated polishing device includes a machine body 1, a sand sliding device 2 and a polishing device 3, and the sand sliding device 2 and the polishing device 3 are both installed on the machine body 1.

[0041] The polishing device 3 includes a road wheel assembly 31 and a rubber wheel assembly 32. The road wheel assembly 31 is mounted on the machine body 1 for mounting the test piece, and the machine body 1 has a rotating mechanism for driving the road wheel assembly 31 to rotate, and the rotating mechanism can be composed of power parts such as a motor and a reducer. The rubber wheel assembly 32 is used to abut against the test piece on the road wheel assembly 31, and the rubber wheel assembly 32 has a counterweight for pressing downward to adjust the pressure of the rubber wheel assembly 32 on the road wheel assembly 31. The outer shell of the rubber wheel assembly 32 has a feed channel 4 corresponding to the sand chute device 2, and the inlet of the feed channel 4 faces the road wheel assembly 31 relative to the outlet of the sand chute device 2, so that the sand material of the sand chute device 2 can fall onto the test piece of the rubber wheel assembly 32 through the feed channel 4.

[0042] Reference Figure 2 The sand sliding device 2 includes a mounting frame 5, a conveyor belt 6, a storage hopper 7, a disturbance member 8 and a driving mechanism 9. The mounting frame 5 is mounted on the machine body 1, and the conveyor belt 6 is conveyed on the mounting frame 5 and the discharge end along the conveying direction is located above the entrance of the feed channel 4. The storage hopper 7 is mounted on the mounting frame 5 and located above the middle of the conveyor belt 6. The bottom end of the storage hopper 7 forms a discharge port facing the conveyor belt 6, and the disturbance member 8 is rotatably connected to the inner cavity of the storage hopper 7. The driving mechanism 9 drives the conveyor belt 6 and the disturbance member 8 to move.

[0043] The sand material is loaded into the storage hopper 7 , and the sand material falls from the discharge port onto the conveyor belt 6 , and then the conveyor belt 6 transports the sand material to the feed channel 4 .

[0044] The mounting frame 5 includes a base 51, a bearing seat 52, an adjusting member 53 and a locking member 54. The bearing seat 52 includes a mounting plate 521 and a rotating roller 522. The mounting plates 521 have two and are opposite to each other. The rotating rollers 522 have two. The two rotating rollers 522 are both rotatably connected between the two mounting plates 521 and are respectively located at two ends of the mounting plates 521 that are away from each other. The axes of the two rotating rollers 522 are parallel. A connecting plate 12 is fixed to the side of the storage hopper 7. The connecting plate 12 is detachably connected to the mounting plate 521 by bolts to install the storage hopper 7.

[0045] The conveyor belt 6 is sleeved on the rotating roller 522 , and the rotating roller 522 rotates to drive the conveyor belt 6 to transport; in this embodiment, the conveyor belt 6 is preferably a rack conveyor belt, and the rotating roller 522 has teeth that cooperate with the conveyor belt 6 .

[0046] The base 51 is fixedly mounted on the machine body 1, and the adjusting member 53 is in the shape of a round rod with an axis parallel to the axis of the rotating roller 522, and one end of the adjusting member 53 is fixed on the mounting plate 521 and is opposite to the middle of the conveyor belt 6, and the end of the adjusting member 53 away from the mounting plate 521 is slidably penetrated on the base 51 along its own axis, and the adjusting member 53 is slid off the base 51 to separate the hopper 7 and the conveyor belt 6 from the machine body 1 for easy maintenance and cleaning. In addition, the adjusting member 53 can be rotated in the base 51 to drive the conveyor belt 6 and the hopper 7 to move together, so that when the hopper 7 is blocked from dropping materials to the conveyor belt 6, the conveyor belt 6 and the hopper 7 can be driven to shake by repeatedly rotating the adjusting member 53 to clear the material feeding path.

[0047] Reference Figure 2 and Figure 3 The locking member 54 is a rod with a thread, preferably a bolt in this embodiment, and the locking member 54 is threadedly moved on the base 51 along the axial direction of the vertical adjustment member 53. The base 51 has at least one locking member 54, and preferably two locking members 54 on the base 51 in this embodiment.

[0048] The locking member 54 extends into the inner cavity of the base 51 and abuts against the adjusting member 53. The outer wall of the adjusting member 53 is provided with a travel groove 11 along its circumference for the locking member 54 to abut against. The travel groove 11 corresponds to the locking member 54 one by one. The locking member 54 abuts against the travel groove 11 to limit the displacement of the adjusting member 53 in the axial direction. The friction between the locking member 54 and the adjusting member 53 makes it difficult for the adjusting member 53 to rotate without other external forces, so as to improve the stability of the adjusting member 53 when the feeding path is unblocked.

[0049] In addition, the locking member 54 can move in the stroke groove 11 at a central angle less than 45° relative to the adjusting member 53, and when the adjusting member 53 rotates, the discharge end of the conveyor belt 6 is always opposite to the feeding channel 4, so as to limit the excessive rotation of the adjusting member 53 and cause the sand in the storage hopper 7 to pour out.

[0050] Reference Figure 3 The disturbance member 8 includes a rotating shaft 81 and a stirring rod 82. The rotating shaft 81 rotates in the storage hopper 7 and the axis of the rotating shaft 81 is parallel to the axis of the rotating roller 522. The stirring rods 82 are distributed on the rotating shaft 81 along the circumference of the rotating shaft 81, and all the stirring rods 82 are located in the storage hopper 7. The rotating shaft 81 drives the stirring rods 82 to rotate so as to stir the sand in the storage hopper 7 and improve the smoothness of the sand feeding.

[0051] Reference Figure 2 and Figure 3In this embodiment, the driving mechanism 9 includes a sprocket 91, a chain 92 and a rotation source 93. There are two sprockets 91, one end of which is a rotating roller 522 passing through the outside of the mounting plate 521, and one end of the rotating shaft 81 passing through the outside of the storage hopper 7. The two sprockets 91 are respectively fixed and sleeved on the rotating roller 522 and the end of the rotating shaft 81 located outside, and the chain 92 is engaged with the two sprockets 91. The rotation source 93 is preferably a reduction motor, and the output end of the rotation source 93 is coaxially connected to the rotating roller 522 connected to the sprocket 91. In other embodiments, the driving mechanism 9 can also be a conveyor belt that is matched with the rotating roller 522 and the rotating shaft 81, and a rotation source 93 that drives the rotating roller 522 to rotate.

[0052] When the rotating source 93 drives the rotating roller 522 to rotate, the rotating roller 522 drives the conveyor belt 6 to transmit, and at the same time drives the rotating shaft 81 to rotate synchronously through the sprocket 91 and the chain 92, so that the stirring rod 82 stirs the sand material in the storage hopper 7, so that the sand material is not easily blocked in the storage hopper 7.

[0053] Reference Figure 2 Furthermore, the rotation source 93 is connected to the rotation roller 522 of the two rotation rollers 522 that is away from the feed channel 4. When conveying abrasive materials, the gravity of the rotation source 93 causes the rotation source 93 to abut against the machine body 1, so that the rotation roller 522 away from the feed channel 4 is lower than the rotation roller 522 close to the feed channel 4, so that the conveyor belt 6 is tilted upward along the conveying direction, so that the abrasive materials tend to move away from the feed channel 4 when the conveying stops, so as to more accurately control the measurement of the abrasive materials entering the feed channel 4. The rotation source 93 is lifted upward to drive the position adjustment member to rotate.

[0054] Reference Figure 2 and Figure 3 In order to improve the stability of the sand material, a feeding gap 10 is formed between the side of the hopper 7 close to the feed channel 4 along the conveying direction of the conveyor belt 6 and the surface of the conveyor belt 6, and the sand material dropped from the hopper 7 onto the conveyor belt 6 is moved out from the feeding gap 10. The side of the hopper 7 away from the feed channel 4 along the conveying direction of the conveyor belt 6, and the two opposite sides of the hopper 7 perpendicular to the conveying direction of the conveyor belt 6 are against the surface of the conveyor belt 6 to limit the sand material from falling out from the end of the conveyor belt away from the feed channel 4. Furthermore, the hopper 7 gradually expands in the direction away from the conveyor belt 6 to facilitate the addition of materials into the hopper 7.

[0055] The implementation principle of the accelerated polishing device of the embodiment of the present application is as follows: the abrasive material is placed in the storage hopper 7, and then the rotating source 93 is started, and the rotating source 93 drives the rotating roller 522 to rotate, so that the feeding conveyor moves. The sprocket 91 and the chain 92 cooperate to drive the rotating shaft 81 to rotate when the conveyor belt 6 is conveyed, so that the stirring rod 82 stirs in the storage hopper 7. The abrasive material falls onto the conveyor belt 6 under the stirring of the stirring rod 82 and leaves the storage hopper 7 from the feeding gap 10, and then the conveyor belt 6 drives the abrasive material to move and fall out from one end of the conveyor belt 6 close to the feeding channel 4, so that the abrasive material falls onto the test piece for polishing inspection through the feeding channel 4.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
