Description

Technical Field

[0001] The utility model relates to the technical field of lifting and unloading equipment, in particular to a lifting and unloading device for an asphalt granular material mixer. Background Art

[0002] The lifting and unloading device of the asphalt aggregate mixer is a key component used to lift and unload the mixed asphalt aggregate from the mixer into a transport vehicle or other production equipment.

[0003] On the conveyor belt of the existing lifting and unloading equipment, some are equipped with a circle of cross-bracing blocking plates for blocking and limiting the materials to facilitate the lifting of the materials. Some of the existing lifting and unloading equipment are also equipped with two long strip blocking plates for blocking and intercepting the materials on the conveyor belt to prevent the materials from leaking and spilling from both sides of the conveyor belt. However, in order to ensure the blocking effect on the materials, the two ends of the cross-bracing blocking plate are mostly directly in contact with the two long strip blocking plates to eliminate the sliding gap therebetween, which causes the two ends of the cross-bracing blocking plate to be in continuous contact and wear with the two long strip blocking plates for a long time. The long-term contact and wear will cause excessive wear and consumption to the cross-bracing blocking plate and the long strip blocking plate, thereby reducing the service life of the cross-bracing blocking plate and the long strip blocking plate. Utility Model Content

[0004] In view of this, the utility model provides a lifting and unloading device for an asphalt granular material mixer to solve the problem that the two ends of the cross-bracing material blocking plate will continuously contact and wear with the two long strip material blocking plates for a long time. The long-term contact and wear will cause excessive wear and consumption to the cross-bracing material blocking plate and the long strip material blocking plate, thereby reducing the service life of the cross-bracing material blocking plate and the long strip material blocking plate.

[0005] The technical solution proposed by the utility model is: an asphalt granular material mixer lifting and unloading device, specifically comprising: a U-shaped support frame and an inclined bearing plate; the U-shaped support frames are provided with two U-shaped support frames in a form of being far away from each other, the two U-shaped support frames are provided with one high and one low, and the inclined bearing plate is welded and fixed above the space between the two U-shaped support frames;

[0006] Two inverted U-shaped mounting frames are symmetrically welded on the two long sides of the inclined bearing plate. The U-shaped mounting frames are in the form of long strips and a row of rollers are rotatably mounted inside. Two blocking belts are symmetrically tensioned on the two rows of rollers.

[0007] A conveying roller is rotatably installed in the top opening of the U-shaped support frame, and a lifting conveyor belt is tensioned between two conveying rollers. A circle of cross-bracing material-blocking plates that are relatively perpendicular to the lifting conveyor belt are fixed on the lifting conveyor belt. When the cross-bracing material-blocking plates are rotated and placed on the upper layer of the lifting conveyor belt and above the inclined bearing plate, the two ends are in frictional contact with the two material-blocking belts.

[0008] Furthermore,

[0009] A material receiving box is sleeved and welded on the U-shaped support frame described above, and the bottom part of the lifting conveyor belt extends and is inserted into the material receiving box.

[0010] Furthermore,

[0011] When the horizontal support and material blocking plate rotates and is placed inside the material receiving box, it comes into scraping contact with the asphalt pellets received inside the material receiving box.

[0012] Furthermore,

[0013] One side plate of the material receiving box located below the lifting conveyor belt is set with a reduced height, and a space for the lifting conveyor belt to pass through is formed between this side plate and the two longitudinal support side plates of the material receiving box.

[0014] Furthermore,

[0015] The upper layer of the lifting conveyor belt abuts against the top end of the inclined bearing plate.

[0016] Furthermore,

[0017] A driving device is fastened by bolts to the outer side of the top part of one vertical support plate of the U-shaped support frame described above, and the conveyor roller shafts on the corresponding side are connected for transmission.

[0018] Furthermore,

[0019] An asphalt pellet mixing machine is fixedly arranged above the bottom part of the lifting conveyor belt, and the bottom discharge pipe of the asphalt pellet mixing machine is vertically aligned with the bottom part of the lifting conveyor belt.

[0020] An asphalt pellet mixing machine lifting and discharging device provided by the present utility model has the following beneficial effects:

[0021] First, the two material blocking belts, as the blocking and intercepting components for asphalt pellets, are rotatably installed. This enables the upper row of horizontal support and material blocking plates to drive the two material blocking belts to rotate synchronously through friction during the process of lifting and conveying the asphalt pellets. When the two material blocking belts rotate synchronously with the upper row of horizontal support and material blocking plates, the relative sliding and wear at both ends between them and the upper row of horizontal support and material blocking plates can be eliminated. Compared with the prior art in which the blocking and intercepting components are set as two long strip-shaped material blocking plates and the two ends of the upper row of horizontal support and material blocking plates directly abut against the two long strip-shaped material blocking plates, it can avoid the excessive wear caused by the two ends of the upper row of horizontal support and material blocking plates continuously abutting against the two long strip-shaped material blocking plates for a long time, which helps to extend the service life of the horizontal support and material blocking plates as the blocking and intercepting components.

[0022] Second, when the cross brace material baffle is rotated and placed inside the material receiving box, it comes into contact with and scrapes the asphalt pellets received inside the material receiving box. At this time, through the rotation and scraping effect of the cross brace material baffle, the asphalt pellets received and collected inside the material receiving box can be loaded onto the lifting conveyor belt. This enables the asphalt pellets received and collected in the material receiving box to be directly lifted and conveyed for feeding using the lifting conveyor belt, eliminating the need to additionally configure a conveying and feeding mechanism similar to the lifting conveyor belt for the material receiving box, which helps reduce the overall cost and power consumption of the unloading device.

[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Please refer to Figures 1 to 5 ;

[0041] Embodiment 1:

[0042] The utility model proposes a lifting and unloading device for an asphalt granular material mixer, comprising: a U-shaped support frame 1 and an inclined bearing plate 6; two U-shaped support frames 1 are arranged in a form far away from each other, the two U-shaped support frames 1 are arranged one high and one low, and the inclined bearing plate 6 is welded and fixed above the space between the two U-shaped support frames 1;

[0043] Two inverted U-shaped mounting frames 601 are symmetrically welded on the two long sides of the inclined bearing plate 6. The U-shaped mounting frames 601 are in a long strip structure, and a row of rollers 602 are rotatably mounted inside. Two blocking belts 603 are symmetrically tensioned on the two rows of rollers 602.

[0044] A conveying roller 7 is rotatably installed in the top opening of the U-shaped support frame 1, and a lifting conveyor belt 3 is tensioned between two conveying rollers 7. A circle of horizontal support material blocking plates 301 which is relatively perpendicular to the lifting conveyor belt 3 is fixed on the lifting conveyor belt 3. When the horizontal support material blocking plates 301 are rotated and placed on the upper layer of the lifting conveyor belt 3 and above the inclined bearing plate 6, the two ends thereof are in frictional contact with the two material blocking belts 603;

[0045] A circle of horizontal support blocking plates 301 can intercept and limit the asphalt granules being transported obliquely upward on the lifting conveyor belt 3, so as to prevent the asphalt granules from sliding down along the inclined lifting conveyor belt 3 during the process of oblique upward transportation, causing the lifting conveyor belt 3 to be unable to perform normal and effective lifting and transportation of the asphalt granules thereon, which helps to ensure the normal and effective implementation of the lifting and transportation function of the lifting conveyor belt 3;

[0046] The two blocking belts 603 are arranged on both sides of the lifting conveyor belt 3 and are in contact with the upper row of cross-bracing blocking plates 301, so as to block and intercept the asphalt granules transported on the lifting conveyor belt 3, thereby preventing the asphalt granules from being discharged and spilled from the openings between the two ends of the upper row of cross-bracing blocking plates 301 during the lifting and conveying process, thereby preventing the asphalt granules from being wasted due to leakage. This enables the lifting conveyor belt 3 to perform relatively complete and thorough lifting and conveying of the asphalt granules thereon, effectively reducing the amount of asphalt granules leaking from the lifting conveyor belt 3 during the conveying process, and thus helping to indirectly increase the lifting and conveying capacity of the conveyor belt 3 and improve the carrying efficiency.

[0047] The two material retaining belts 603 serve as the blocking and intercepting components for the asphalt aggregate, and are rotatably installed. This enables, during the process of lifting and conveying the asphalt aggregate, the upper row of cross-bracing material retaining plates 301 to drive the two material retaining belts 603 to rotate synchronously through frictional force as the lifting conveyor belt 3 rotates. When the two material retaining belts 603 rotate synchronously with the upper row of cross-bracing material retaining plates 301, relative sliding and wear at both ends between them and the upper row of cross-bracing material retaining plates 301 can be eliminated. Compared with the prior art where the blocking and intercepting components are set as two long strip-shaped material retaining plates and the two ends of the upper row of cross-bracing material retaining plates 301 directly abut against the two long strip-shaped material retaining plates, it is possible to avoid excessive wear caused by the two ends of the upper row of cross-bracing material retaining plates 301 continuously abutting against the two long strip-shaped material retaining plates for a long time, which helps to extend the service life of the cross-bracing material retaining plates 301 as the blocking and intercepting components.

[0048] Preferably,

[0049] A receiving box 5 is sleeved and welded on the low U-shaped support frame 1, and the bottom end part of the lifting conveyor belt 3 extends and is inserted into the receiving box 5.

[0050] Preferably,

[0051] When the cross-bracing material retaining plate 301 rotates and is placed inside the receiving box 5, it makes scraping contact with the asphalt aggregate contained inside the receiving box 5. At this time, through the rotation and scraping effect of the cross-bracing material retaining plate 301, the asphalt aggregate collected and contained inside the receiving box 5 can be loaded onto the lifting conveyor belt 3. This enables the asphalt aggregate collected in the receiving box 5 to be directly lifted and conveyed for feeding by the lifting conveyor belt 3, eliminating the need to additionally configure a conveying and feeding mechanism similar to the lifting conveyor belt 3 for the receiving box 5, which helps to reduce the overall cost and power consumption of the unloading device.

[0052] On the basis of Embodiment 1, Embodiment 2:

[0053] One side plate of the receiving box 5 located below the lifting conveyor belt 3 is set with a reduced height, and a space for the lifting conveyor belt 3 to pass through is formed between this side plate and the two longitudinal support side plates of the receiving box 5; the upper layer of the lifting conveyor belt 3 abuts against the top end of the inclined bearing plate 6.

[0054] Preferably,

[0055] A driving device 2 is fastened by bolts to the outer side of the top end part of an upright support plate of the high U-shaped support frame 1, and the conveyor roller 7 on the corresponding side of the driving device 2 is axially connected for transmission.

[0056] Preferably,

[0057] An asphalt granular material mixer 4 is fixedly arranged above the bottom end of the lifting conveyor belt 3, and the bottom discharge pipe of the asphalt granular material mixer 4 is vertically opposite to the bottom end of the lifting conveyor belt 3;

[0058] When the asphalt aggregate mixer 4 discharges the asphalt aggregates through the discharge pipe to the bottom part of the lifting conveyor belt 3, the discharged asphalt aggregates will be scattered. The receiving box 5 can collect the scattered asphalt aggregates in this case, so as to avoid the asphalt aggregates being scattered over a large area without necessary collection measures, which causes the trouble of subsequent large-scale cleaning and collection. The operation is convenient and useful, which helps to reduce the workload of workers.

[0059] The working principle of this embodiment is as follows: the asphalt granular material mixer 4 discharges asphalt granular materials to the bottom part of the lifting conveyor belt 3 through the discharge pipe. The lifting conveyor belt 3 is used to lift the asphalt granular materials discharged and carried thereon to the subsequent equipment for asphalt production. When the asphalt granular material mixer 4 discharges asphalt granular materials to the bottom part of the lifting conveyor belt 3 through the discharge pipe, the discharged asphalt granular materials will be scattered. The receiving box 5 can collect the scattered asphalt granular materials in this case. When the cross-bracing material blocking plate 301 is rotated and placed inside the receiving box 5, it pushes and scrapes the asphalt granular materials received inside the receiving box 5. At this time, the cross-bracing material blocking plate 301 can load the asphalt granular materials collected inside the receiving box 5 onto the lifting conveyor belt 3 through its rotation and pushing and scraping effect, and the lifting conveyor belt 3 is used to implement lifting, conveying and loading;

[0060] A circle of cross-bracing material blocking plates 301 can intercept and limit the asphalt granules being transported obliquely upward on the lifting conveyor belt 3, so as to prevent the asphalt granules from sliding down along the inclined lifting conveyor belt 3 during the process of being transported obliquely upward, causing the lifting conveyor belt 3 to be unable to perform normal and effective lifting and transportation of the asphalt granules thereon;

[0061] The two blocking belts 603 are arranged on both sides of the lifting conveyor belt 3 and are in contact with the upper row of cross-bracing blocking plates 301, so as to block and intercept the asphalt particles transported on the lifting conveyor belt 3, thereby preventing the asphalt particles from leaking out of the opening between the two ends of the upper row of cross-bracing blocking plates 301 during the lifting and transportation process, thereby causing waste.

[0063] 1. The drawings of the embodiments of the present utility model only relate to the structures related to the embodiments of the present utility model, and other structures may refer to the usual designs.

[0064] 2. In the absence of conflict, the embodiments of the present invention and the features therein may be combined with each other to obtain new embodiments.

[0065] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
