Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to a construction material conveying device. Background Art

[0002] During the production and construction of construction materials, conveying devices are required to transport the materials. For example, during the production and paving of asphalt, a conveying device is required to transport the asphalt. In related technologies, the conveying devices used to transport asphalt are mostly screw loaders. During the production of asphalt, the conveying device can transport the asphalt mixture to the mixing equipment or reaction tank; it can also serve as an auxiliary equipment for the paver during paving, transporting asphalt from the storage container to the transport vehicle or the paver hopper. When the conveying device transports asphalt, in order to adapt to the height of different equipment or hoppers, the loading height needs to be flexibly adjusted during the transportation process.

[0003] The patent document with the authorization announcement number CN117023015B discloses a spiral feeding device for asphalt, including a feeding barrel, a support seat, an adjusting mechanism, a feeding hopper and a discharging mechanism. A feeding screw is rotatably installed in the feeding barrel, and the feeding screw is driven to rotate by a motor. The starting end of the feeding barrel is rotatably installed on the support seat, and the adjusting mechanism includes an electric telescopic rod, which pushes the feeding barrel to rotate with the connection between the feeding barrel and the support seat as the axis. The feeding hopper is fixed to the starting end of the feeding barrel and the bottom is connected to the feeding barrel. The mechanism includes a material distribution box, a material receiving box, a push rod and multiple flaps. The material distribution box is fixed to the end of the feeding barrel through a pipe and is connected to the feeding barrel. The bottom of the material distribution box is provided with an opening. Multiple flaps are installed side by side in the material distribution box to cover the opening. One side of each flap is rotatably connected to the material distribution box. The material receiving box is slidably installed in the opening. The material receiving box is connected up and down. The push rod is fixed to the upper part of the material receiving box and can abut against the flap located directly above the material receiving box. The material receiving box is driven by an electric adjustment screw to move along the length direction of the opening.

[0004] The spiral feeding device of the patent document is provided with an adjusting mechanism and a discharging mechanism. The height of the end of the feeding barrel is adjusted by the adjusting mechanism so that the feeding barrel can adapt to the asphalt conveying needs at different heights. The discharging box, the flap and the receiving box of the discharging mechanism cooperate to change the discharge position of the asphalt without stopping the asphalt conveying, and the asphalt can be discharged into different containers in the asphalt conveying state.

[0005] The spiral feeding device of the above patent document uses several independent flaps to cover the outlet to block the discharge of asphalt during the operation of discharging at different positions. The asphalt will not be discharged until the flap is opened. During long-term use, asphalt is easy to accumulate inside the discharge mechanism, especially when the asphalt is discharged through the discharge pipe far away from the end. The flow distance of the asphalt in the distribution box is long. Since the fluidity of the asphalt is poor and it has a certain viscosity, the asphalt is more likely to accumulate and solidify during the flow of the distribution box. The asphalt with a lot of accumulated asphalt in the internal structure of the discharge mechanism is not easy to clean, and since there is asphalt on the top of the flap, the asphalt blocking the flap when opening may cause the opening to be small, resulting in a small asphalt discharge volume, affecting the asphalt feeding speed.

[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] like Figures 1 to 7 As shown, the construction material conveying device of the present invention includes a loading barrel 1 and a loading mechanism and an adjusting mechanism arranged inside the loading barrel 1. The loading end of the loading barrel 1 is provided with a feeding port 11 for adding materials, and the discharging end of the loading barrel 1 is provided with a discharging trough 12 for discharging materials. The loading mechanism includes a rotating shaft 3 rotatably installed inside the loading barrel 1 and a spiral blade 1 31 fixed to the rotating shaft 3. When the rotating shaft 3 rotates, the spiral blade 1 31 is driven to rotate synchronously and the material in the loading barrel 1 is conveyed from the loading end to the discharging end. The adjusting mechanism includes a spiral blade 2 32 that is slidably matched with the rotating shaft 3, an adjusting member 4 that is rotatably assembled with the spiral blade 2 32, a limiting component that limits the relative state of the spiral blade 2 32 and the rotating shaft 3, and a moving component that pushes the spiral blade to slide along the rotating shaft 3. The adjusting member 4 is connected to one end of the spiral blade 2 32. The end of the adjusting member 4 fixed to the spiral blade 2 32 is in contact with the inner wall of the upper barrel 1. The adjusting member 4 slides along the discharge trough 12. The adjusting member 4 is provided with a discharge port 421, which slides along the discharge trough 12. When the adjusting member 4 slides inside the upper barrel 1, the position of the discharge port 421 and the discharge trough 12 is adjusted, thereby changing the actual discharge position of the upper barrel 1.

[0042] The feeding cylinder 1 is further provided with a driving structure for driving the rotation of the rotating shaft 3, the driving structure comprising a driving source 2, a driving gear 21 and a connecting gear 22, the driving source 2 being installed outside the feeding cylinder 1, the driving source 2 can be a motor, the driving end of the driving source 2 being connected with the driving gear 21, the connecting gear 22 being fixed to one end of the rotating shaft 3, the connecting gear 22 being engaged with the driving gear 21, the driving source 2 driving the driving gear 21 to rotate when working, the connecting gear 22 rotating under the engagement with the driving gear 21 and driving the rotating shaft 3 to rotate.

[0043] The driving structure is used to drive the rotating shaft 3 to rotate according to the feeding requirement. In other embodiments, the driving structure can only comprise the driving source 2, the driving source 2 being installed outside the feeding cylinder 1, the driving end of the driving source 2 being directly connected with one end of the rotating shaft 3. In other embodiments, the driving structure can further comprise the driving source 2 and two transmission wheels, the driving source 2 being installed outside the feeding cylinder 1, one transmission wheel being fixed to one end of the rotating shaft 3, the other transmission wheel being fixed to the driving end of the driving source 2, the two transmission wheels being sleeved with a transmission belt outside, the driving source 2 driving the transmission wheel directly connected therewith to rotate when working, the other transmission wheel rotating under the transmission of the transmission belt.

[0044] As shown in Figures 3 to 5 , the rear side of the spiral blade two 32 is fixed with a connecting plate 33, a circular hole being formed in the center of the connecting plate 33, the connecting plate 33 being sleeved on the rotating shaft 3 through the circular hole in the center. The adjusting part 4 comprises a connecting part 41 and an adjusting part 42, the connecting part 41 being a plate-shaped part consistent with the cross-sectional shape of the feeding cylinder 1, the connecting part 41 being in sliding fit with the feeding cylinder 1, the connecting plate 33 being rotatable in abutment with the connecting part 41, the adjusting part 42 being an arc-shaped plate, a discharge port 421 being formed on the adjusting part 42.

[0045] As shown in Figure 6 , the limiting assembly comprises a magnetic attraction part 35, a limiting plug rod 36 and a return spring 362, a limiting sliding groove 34 being formed on the surface of the rotating shaft 3, the limiting sliding groove 34 being parallel to the axis of the rotating shaft 3. The limiting plug rod 36 is in sliding connection with the connecting plate 33 along the radial direction of the connecting plate 33, specifically, the connecting plate 33 is fixed with a connecting block 331, one end of the limiting plug rod 36 being in sliding connection with the connecting block 331, the other end of the limiting plug rod 36 being fixed with a plug-in block 361, the plug-in block 361 being in movable plug-in connection with the limiting sliding groove 34, the return spring 362 being sleeved between the plug-in block 361 and the connecting block 331.

[0046] The magnetic element 35 is an electromagnetic component that generates a magnetic force when powered. The magnetic element 35 can be an electromagnet and is annular in shape. The magnetic element 35 is coaxially arranged with the rotating shaft 3, and the limiting rod 36 is located inside the magnetic element 35. The limiting rod 36 is made of a magnetic material. When the magnetic element 35 is powered, the limiting rod 36 slides toward the magnetic element 35 under the magnetic attraction of the magnetic element 35, causing the plug block 361 on the limiting rod 36 to disengage from the limiting groove 34, and the return spring 362 is compressed and charged. When the magnetic element 35 is powered off, the elastic force of the return spring 362 is released, driving the limiting rod 36 away from the magnetic element 35. When the limiting groove 34 on the rotating shaft 3 is aligned with the magnetic element 35, the plug block 361 on the limiting rod 36 reinserts into the limiting groove 34.

[0047] In order to ensure the efficient operation of the limiting component and ensure that the relative rotation of the spiral blade 2 32 and the rotating shaft 3 is quickly limited, a plurality of limiting grooves 34 can be evenly opened on the circumference of the rotating shaft 3. In order to ensure the limiting strength of the limiting component on the rotating shaft 3 and the spiral blade 2 32, a plurality of limiting rods 36 can also be set.

[0048] When the limiting rod 36 is engaged with the limiting slot, the connecting plate 33 is fixed circumferentially relative to the rotating shaft 3, and the connecting plate 33 rotates synchronously with the rotating shaft 3. After the limiting rod 36 is disengaged from the limiting slot, the connecting plate 33 is circumferentially connected to the rotating shaft 3, and rotation of the rotating shaft 3 does not drive the connecting plate 33 to rotate. Spiral blade 1 31 is located in the front half of the rotating shaft 3, and spiral blade 2 32 is slidably connected to the rear half of the rotating shaft 3. After the rear end of spiral blade 1 31 contacts or overlaps the front end of spiral blade 2 32, the limiting assembly causes spiral blade 2 32 to rotate with the rotating shaft 3. Spiral blades 1 31 and 32 can rotate synchronously and jointly transport material from the loading end of the loading barrel 1 to the unloading end of the loading barrel 1.

[0049] like Figure 5As shown, the moving assembly includes a driving member, an adjusting screw 43 and a guide rod 44. The driving member is installed on the outside of the upper barrel 1 and is located at the discharge end of the upper barrel. The driving member can be a motor, and the driving end of the driving member is fixed to the adjusting screw 43. The adjusting screw 43 and the guide rod 44 are both rotatably assembled in the upper barrel 1. The adjusting screw 43 and the guide rod 44 are located on the upper side of the upper barrel 1. The adjusting screw 43 and the guide rod 44 are parallel to the length direction of the upper barrel 1. The connecting portion 41 is threadedly connected to the adjusting screw 43, and the connecting portion 41 is slidably connected to the guide rod 44. When conveying materials, the discharge position of the material is first set, and then the driving member is started. The driving member drives the adjusting member 4 to slide in the upper barrel 1 through the adjusting screw 43 and the guide rod 44. After the discharge port 421 reaches the preset discharge position, the driving member stops working. Through the cooperation between the moving assembly and the adjusting member 4, it is convenient to flexibly change the discharge position according to the material conveying requirements during the working process.

[0050] The moving assembly can also be used to clean impurities remaining on the surfaces of spiral blade 1 31 and spiral blade 2 32 after material conveying is completed. The relative rotation between spiral blade 2 32 and rotating shaft 3 is limited by the moving assembly, that is, the power supply of magnetic element 35 is disconnected, and the limiting rod 36 is inserted into the limiting slot 34. The driving element is then activated, and spiral blade 2 32 is gradually pushed along the limiting slot 34 through the adjusting element 4 until the front end of spiral blade 2 32 begins to overlap with the rear end of spiral blade 1 31, and the end of spiral blade 2 32 is in contact with the spiral surface of spiral blade 1 31, and the end of spiral blade 1 31 is in contact with the spiral surface of spiral blade 2 32. Then the driving structure is started and drives the rotating shaft 3 to rotate. The spiral blade 2 32 rotates synchronously with the spiral blade 1 31. The moving component continues to push the spiral blade 2 32 to slide forward. When the spiral blade 2 32 slides along the spiral surface of the spiral blade 1 31, the end of the spiral blade 1 31 scrapes off the material remaining on the spiral surface of the spiral blade 2 32, and the end of the spiral blade 2 32 scrapes off the material remaining on the spiral surface of the spiral blade 1 31.

[0051] Both spiral blade 2 32 and spiral blade 1 31 have two spiral surfaces. In order to achieve comprehensive cleaning of the materials on the spiral surfaces of spiral blade 1 31 and spiral blade 2 32, the difficulty of subsequent manual cleaning can be reduced. The above cleaning steps can be repeated, and before the second cleaning, the direction of overlap of spiral blade 1 31 and spiral blade 2 32 can be adjusted. Specifically, after the moving component pushes spiral blade 2 32 to move until its front end overlaps with the rear end of spiral blade 1 31, the driving component 1 is paused, and the limit of the rotating shaft 3 and spiral blade 2 32 is contacted at the same time. Thereafter, the rotating shaft 3 is driven by the driving structure to rotate 360°, and spiral blade 1 31 rotates synchronously with the rotating shaft 3, and the other spiral surface of spiral blade 1 31 is made to fit with the other spiral surface of spiral blade 2 32. The spiral blade 2 32 and the rotating shaft 3 are again limited by the limiting component, and the moving component and the driving structure are started to work, and the cleaning operation of the other spiral surface of spiral blade 1 31 and spiral blade 2 32 is completed.

[0052] The complete working process of the construction material conveying device provided by the present invention is as follows:

[0053] During the production process, first, according to the material conveying requirements, the driving part in the moving assembly is started. The driving part drives the adjusting part 4 to slide in the loading barrel 1 through the adjusting screw 43 and the guide rod 44. The discharge port 421 on the adjusting part 4 slides along the discharge trough 12 until the discharge port 421 reaches the preset discharge position. The driving part stops working, thereby changing the actual discharge position of the loading barrel 1 and allowing the material to be discharged from the specified discharge position.

[0054] Construction materials are then added to the loading barrel 1 through the feed port 11 at the loading end. Construction materials can continue to be added through the feed port 11. The drive mechanism is then activated, driving the rotating shaft 3. This rotation drives the spiral blade 1 31 affixed thereto. At this point, the spiral blade 2 32, restrained by the limiting rod 36 and the limiting chute 34, rotates synchronously with the rotating shaft 3. The synchronized rotation of the spiral blades 1 31 and 32 transports the material in the loading barrel 1 from the loading end to the discharge end. The material is discharged through the discharge port 421.

[0055] After material conveying is completed, the power supply to the magnetic element 35 in the limiting assembly is disconnected, allowing the limiting rod 36 to be inserted into the limiting slot 34 under the elastic force of the return spring 362. At this time, the connecting plate 33 is fixed in the circumferential direction relative to the rotating shaft 3, and the connecting plate 33 rotates synchronously with the rotating shaft 3. The driving element in the moving assembly is activated, and the adjusting element 4 gradually pushes the second spiral blade 32 to slide along the limiting slot 34 until the front end of the second spiral blade 32 begins to overlap with the rear end of the first spiral blade 31, and the end of the second spiral blade 32 is in contact with the helical surface of the first spiral blade 31.

[0056] Start the driving structure and drive the rotating shaft 3 to rotate, the spiral blade 2 32 rotates synchronously with the spiral blade 1 31, and the moving component continuously pushes the spiral blade 2 32 to slide forward. When the spiral blade 2 32 slides along the spiral surface of the spiral blade 1 31, the end of the spiral blade 1 31 scrapes off the material remaining on the spiral surface of the spiral blade 2 32, and the end of the spiral blade 2 32 scrapes off the material remaining on the spiral surface of the spiral blade 1 31.

[0057] In order to achieve comprehensive cleaning of the material on the spiral surfaces of spiral blade 1 31 and spiral blade 2 32, the above cleaning steps are repeated, and before the second cleaning, the driving member is paused, and the limit of the rotating shaft 3 and the spiral blade 2 32 is released. The driving structure drives the rotating shaft 3 to rotate 360°, so that the other spiral surface of spiral blade 1 31 is fitted with the other spiral surface of spiral blade 2 32, and then the spiral blade 2 32 and the rotating shaft 3 are limited again by the limit component, and the moving component and the driving structure are started to complete the cleaning operation of the other spiral surface of spiral blade 1 31 and spiral blade 2 32.

[0058] The construction material conveying device provided by the present invention can flexibly adjust the conveying position of the construction materials according to the conveying requirements, and efficiently clean the materials remaining on the spiral blades one and two after the conveying operation is completed, thereby reducing the difficulty of manual cleaning and effectively improving work efficiency.

[0059] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
