Description

Technical Field

[0001] The invention belongs to the technical field of asphalt spreading devices, and in particular relates to a pouring type asphalt construction lateral spreading method and a device thereof. Background Art

[0002] Pouring asphalt concrete has good structural waterproofing and low-temperature cracking resistance, and has the characteristics of high temperature and high oil content, which can effectively protect the road foundation. During the construction of poured asphalt, after the lanes on both sides of the road are completed, the middle dividing strip needs to be poured with asphalt concrete. Traditionally, the following two methods are mainly used for laying materials: First, the unloading chute is used for self-unloading, which is slow, the heat loss of the asphalt mixture is large, and the transport vehicle needs to frequently shift the center dividing strip vertically, which is inefficient; second, the manual bucket truck transfers materials, which is inefficient, workers are easily scalded, and the work surface is obviously polluted, which cannot meet the construction requirements.

[0003] The existing paving machine for lateral material distribution, such as a feeding system for lateral material feeding with the authorization publication number CN111877092A, includes a main machine, on which a material receiving system is installed, and also includes a primary lateral feeding device and a secondary belt conveyor; the primary lateral feeding device is arranged in the material receiving system, and the secondary belt conveyor is installed on the outside of the primary lateral feeding device, and the tail of the secondary belt conveyor extends below the discharge port of the primary lateral feeding device; the secondary belt conveyor receives the mixed material conveyed by the primary lateral feeding device and continues to convey the mixed material to the outside; however, the In the first-level horizontal feeding device of the prior art, asphalt concrete is moved by an auger, and crushed stones need to be added to the asphalt concrete as aggregate. When larger stones appear in the crushed stones, the auger is easily stuck with the bottom of the shell. Since the temperature of the asphalt concrete is relatively high, normally between 120°C and 160°C, the auger is stuck by the crushed stones and is difficult to handle. Once it is not handled for a long time, the temperature of the asphalt concrete is easily caused to drop, resulting in poor asphalt concrete pouring effect. At the same time, the asphalt concrete is also easy to adhere to the bottom of the hopper, reducing the moving speed of the asphalt concrete in the hopper.

[0004] Based on this, it is necessary to adopt a pouring asphalt mixture conveying and distributing device that can be heated and insulated, has high unloading efficiency and convenient transportation, and at the same time meets the requirements of conveying high viscosity asphalt concrete, easy cleaning and not easy to clog. Summary of the invention

[0005] In order to solve the problems in the prior art that crushed stones are easily stuck on the auger and the hopper and asphalt concrete is easily adhered to the bottom of the hopper, the present invention provides a pouring asphalt construction lateral spreading method and device thereof.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A lateral material distribution device for pouring asphalt construction of the present invention comprises a vehicle body, a conveying assembly and a transmission assembly, wherein the conveying assembly is arranged at the rear of the vehicle body, and the conveying assembly comprises a hopper, a base plate and an auger, wherein the auger is rotatably connected to the side wall of the hopper, and the base plate is horizontally slidably connected to the bottom of the hopper, and the horizontal sliding direction of the base plate is parallel to the axis of the auger, and the first rotating shaft of the auger is eccentrically arranged on the axial projection surface of the auger, so that the capstan of the auger includes a close portion that slides in contact with the bottom of the hopper and a distant portion that is away from the bottom of the hopper, one end of the transmission assembly is transmission-connected to the vehicle body transmission shaft, and the other end is transmission-connected to the base plate, and the base plate reciprocates in the hopper through the transmission assembly as the transmission shaft rotates, and the first rotating shaft is transmission-connected to the transmission shaft, and the close portion of the auger reciprocates with the base plate to scrape off the asphalt concrete adhered to the base plate.

[0008] Furthermore, the transmission assembly includes a bracket, two rollers and an eccentric wheel, the two rollers are rotatably connected to the side of the outer wall of the base plate, the eccentric wheel is rotatably connected to the bracket, the rim of the eccentric wheel is respectively rollingly fitted with the rims of the two rollers, the second rotating shaft of the eccentric wheel is transmission-connected to the transmission shaft, and the rotation of the eccentric wheel is used to drive the base plate to reciprocate.

[0009] Furthermore, it also includes a third rotating shaft and a plurality of bevel gears, the two bevel gears are connected to the transmission shaft, one end of the first rotating shaft and the second rotating shaft are both provided with bevel gears, the second rotating shaft and the transmission shaft are meshed and driven by the bevel gears, the first rotating shaft and the transmission shaft are meshed and driven by the bevel gears on the third rotating shaft, and the base plate and the auger move synchronously.

[0010] Furthermore, the rotation cycle of the auger is synchronized with the reciprocating motion cycle of the base plate.

[0011] Furthermore, the bottom plate is a semi-cylindrical structure with an opening facing upward, and the axis of the bottom plate is parallel to the axis of the first rotating shaft.

[0012] Furthermore, grooves are provided at the bottom of the two side walls of the hopper parallel to the first rotating shaft, and the two side edges of the bottom plate are respectively slidably sleeved in the grooves at the bottom of the two side walls of the hopper.

[0013] Furthermore, cylinders with diameters greater than the thickness of the bottom plate are respectively arranged on both sides of the bottom plate, the axial surfaces of the cylinders are connected to the side edges of the bottom plate, a circular groove cooperating with the cylinders is arranged in the groove, and the cylinders and the circular grooves cooperate to support the bottom plate.

[0014] Furthermore, asphalt concrete is poured into the hopper, and the vehicle body is moved forward along the side construction position. The first rotating shaft and the second rotating shaft are rotated through the transmission shaft, so that the auger and the base plate form a synchronous periodic motion. The synchronous periodic motion of the auger and the base plate is used to scrape off the asphalt concrete adhered to the base plate.

[0015] The beneficial effects of the present invention are as follows: by eccentrically setting the first rotating shaft of the auger on the axial projection surface of the capstan, the auger can be made to form different distances with the bottom of the hopper within one rotation cycle, and when the close portion is in contact with the bottom of the hopper, there is no gap to jam the stone, and when the stone is jammed between the far portion and the bottom of the hopper, the stone will be squeezed out after the close portion rotates over, and even if the stone is not squeezed out after the close portion rotates to the bottom of the hopper, the bottom plate will form a horizontal reciprocating motion along the axis direction of the first rotating shaft under the action of the transmission component, so the position of the stone in the horizontal direction can be changed, and the stone is misaligned with the capstan of the auger, so as to prevent the auger from being jammed by the stone;

[0016] The movement and stirring of asphalt concrete by the auger and the reciprocating motion of the bottom plate can create a vibration effect on the asphalt concrete, enhance the secondary stirring effect of the asphalt concrete before pouring, and avoid the segregation of the asphalt concrete;

[0017] Through the linkage cooperation between the dragon and the bottom plate, the winch of the auger will form a periodic sliding fit with the bottom plate, and the bottom plate will also form a periodic reciprocating motion. Therefore, when the close part of the winch fits with the bottom plate, the bottom plate will reciprocate at the same time, and the asphalt concrete adhering to the bottom plate will be scraped off, avoiding the long-term accumulation of asphalt concrete on the bottom plate.

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figure 1-3 As shown, a pouring type asphalt construction lateral spreading device of the present invention comprises a vehicle body 1, a conveying assembly and a transmission assembly, wherein the conveying assembly is arranged at the rear of the vehicle body 1, and the conveying assembly comprises a hopper 2, a bottom plate 4 and an auger 3, wherein the auger 3 is rotatably connected to the side wall of the hopper 2, and the bottom plate 4 is horizontally slidably connected to the bottom of the hopper 2, wherein the horizontal sliding direction of the bottom plate 4 is parallel to the axis of the auger 3, and the first rotating shaft 9 of the auger 3 is eccentrically arranged on the radial projection surface of the auger 3, so that the capstan of the auger 3 comprises a close portion slidably fitted with the bottom of the hopper 2 and a distant portion away from the bottom of the hopper 2, When the close part rotates to the bottom of the hopper 2, it rotates and fits with the bottom of the hopper 2, and when the far part rotates to the bottom of the hopper 2, it is separated from the bottom of the hopper 2 by a certain distance. One end of the transmission component is connected to the transmission shaft 6 of the vehicle body 1, and the transmission shaft 6 of the vehicle body 1 is used to drive the wheels to rotate. The other end of the transmission component is connected to the bottom plate 4. The bottom plate 4 reciprocates along the sliding direction in the hopper 2 with the rotation of the transmission shaft 6 through the transmission component. The first rotating shaft 9 is connected to the transmission shaft 6. The close part of the auger 3 reciprocates with the bottom plate 4 to scrape off the asphalt concrete adhered to the bottom plate 4.

[0025] Since crushed stones need to be added as aggregates in asphalt concrete, when larger stones appear in the crushed stones, it is easy to cause the auger 3 to get stuck at the bottom of the hopper 2. Since the temperature of asphalt concrete is relatively high, normally between 120°C and 160°C, the auger 3 is stuck by the crushed stones and is at the bottom, making it difficult to handle. If it is not handled for a long time, it is easy to cause the temperature of the asphalt concrete to drop, resulting in poor asphalt concrete pouring effect. At the same time, there is a gap between the auger 3 and the hopper 2, so some asphalt concrete with smaller particles will remain at the bottom of the shell without being transported to the outside of the shell. Asphalt concrete has a certain viscosity, so it is easy to stick to the bottom of the shell after being at the bottom of the shell for a long time and is difficult to clean;

[0026] Therefore, by eccentrically arranging the first rotating shaft 9 of the auger 3 on the axial projection plane of the winch, the auger 3 can be made to form different distances from the bottom of the hopper 2 within one rotation cycle. If the winch of the auger 3 always maintains the same distance from the bottom of the hopper 2, then when a larger stone is stuck between the winch and the bottom of the hopper 2, the auger 3 may be stuck. Even if the auger 3 is not stuck, it will make it difficult for the asphalt concrete behind the stone to move forward, resulting in a slow discharge speed. Therefore, by changing the position of the first rotating shaft 9 of the auger 3, different distances can be formed between the auger 3 and the bottom of the hopper 2 within one rotation cycle. The distance from the bottom of the hopper 2 changes during the moving cycle. Since there is no gap when the close part fits with the bottom of the hopper 2, the stone will be stuck. When the stone is stuck between the far part and the bottom of the hopper 2, the stone will be squeezed out after the close part rotates over. Even if the stone is not squeezed out after the close part rotates to the bottom of the hopper 2, the bottom plate 4 will form a horizontal reciprocating motion along the axis direction of the first rotating shaft 9 under the action of the transmission component, so the position of the stone in the horizontal direction can be changed, and the stone is misaligned with the capstan of the auger 3 to prevent the auger 3 from being stuck by the stone.

[0027] At the same time, asphalt concrete is prone to separation of slurry and aggregate during long-distance transportation. Asphalt concrete segregation will lead to poor structural and texture characteristics of the paved road surface. Segregation enhances the water permeability of the newly paved asphalt concrete surface layer, and the water entering the gaps in the road surface continuously generates a circulation effect of dynamic water pressure or vacuum negative pressure suction. The water gradually penetrates into the interface between asphalt and aggregate and emulsifies the asphalt, resulting in a decrease in the strength of asphalt concrete. After pouring, it is easy to form peeling, cracking, potholes, pushing and other damage phenomena on the asphalt road surface, which seriously shortens the service life of the asphalt concrete road surface. Therefore, in this embodiment, the movement and stirring of the asphalt concrete by the auger 3 and the reciprocating motion of the base plate 4 can form a vibration effect on the asphalt concrete, enhance the secondary stirring effect of the asphalt concrete before pouring, and avoid the segregation of the asphalt concrete.

[0028] The reciprocating motion of the bottom plate 4 can not only prevent stones from being stuck between the auger 3 and the bottom plate 4, and improve the secondary mixing effect of the asphalt concrete to prevent segregation, but also can scrape off the asphalt concrete adhering to the bottom plate 4 through the linkage with the auger 3. Since the asphalt concrete has a certain viscosity, some of the asphalt concrete gradually adheres to the bottom plate 4 after a long period of use, resulting in a decrease in the moving speed of the asphalt concrete above it, and easily causing blockage in the hopper 2. Therefore, through the linkage between the auger and the bottom plate 4, that is, the winch of the auger 3 will form a periodic sliding fit with the bottom plate 4, and the bottom plate 4 will also form a periodic reciprocating motion. Therefore, when When the close part of the winch is in contact with the bottom plate 4, the bottom plate 4 makes reciprocating motion at the same time, and the asphalt concrete adhering to the bottom plate 4 will be scraped off, avoiding the asphalt concrete from accumulating on the bottom plate 4 for a long time. The auger 3 can not only scrape the asphalt concrete on the bottom plate 4, but also because the winch is in an eccentric state, it can also fit with the side wall of the hopper 2 when its close part rotates to the side wall of the hopper 2. Moreover, since the winch on the auger 3 is spirally wound on the first rotating shaft 9, a certain amount of sliding will be formed at the fitting part, scraping off the asphalt concrete adhering to the side wall of the hopper 2, which can not only avoid blockage, but also increase the moving speed of the asphalt concrete, and avoid its temperature reduction resulting in poor pouring effect.

[0029] In order to realize the transmission effect of the reciprocating motion of the bottom plate 4 through the transmission assembly, in one embodiment, the transmission assembly includes a bracket 5, two rollers 8 and an eccentric wheel 12, the two rollers 8 are rotatably connected to the side of the outer wall of the bottom plate 4, the two rollers 8 are separated by a certain distance, the eccentric wheel 12 is rotatably connected to the bracket 5, so that the eccentric wheel 12 is located in the middle of the two rollers 8, and the rims of the eccentric wheel 12 are respectively rolled and fitted with the rims of the two rollers 8, the second rotating shaft 10 of the eccentric wheel 12 is transmission-connected to the transmission shaft 6, and the rotation of the eccentric wheel 12 is used to drive the bottom plate 4 to reciprocate;

[0030] Since the transmission component is close to the asphalt concrete when working, it is inevitable that some asphalt concrete will adhere to the transmission component. If the transmission component that can achieve reciprocating motion is achieved through a crank-connecting rod mechanism, it is easy to be stuck by the fallen asphalt concrete blocks. Therefore, it is necessary to simplify the structure of the transmission component and only achieve it through the eccentric wheel 12 and two rollers 8; the bracket 5 of the transmission component is connected to the vehicle body 1, and the eccentric wheel 12 rotates between the two rollers 8, and the two rollers 8 will also rotate with the rotation of the eccentric wheel 12 to reduce friction. When the eccentric wheel 12 rotates, it pushes the roller 8 on one side, and by pushing the roller 8, the bottom plate 4 is pushed to one side, and the same is true in the other direction. By pushing the rollers 8 on both sides of the eccentric wheel 12 respectively, the reciprocating motion of the bottom plate 4 is achieved. At the same time, due to its relatively simple structure, it is not easy to be stuck by asphalt concrete.

[0031] Since the first rotating shaft 9 and the transmission shaft 6 are parallel to each other, in order to realize the driving of the first rotating shaft 9 to rotate through the transmission shaft 6, the transmission shaft 6 is used for the transmission of the wheels on the vehicle body 1, and the transmission shaft 6 is connected with a driving assembly, and the driving shaft 6 is driven by the driving assembly. In one embodiment, it also includes a third rotating shaft 11 and a plurality of bevel gears 7, and the two bevel gears 7 are transmission-connected to the transmission shaft 6. A circular rotating gear is provided at one end of the first rotating shaft 9, and bevel gears 7 are also provided at both ends of the third rotating shaft 11. The third rotating shaft 11 is rotationally connected to the vehicle body 1, and the two bevel gears 7 on the third rotating shaft 11 are respectively meshed with the bevel gears 7 on the first rotating shaft 9 and the transmission shaft 6, and one end of the second rotating shaft 10 on the eccentric wheel 12 is also provided with a bevel gear 7. The second rotating shaft 10 and the transmission shaft 6 are meshed and transmitted through the bevel gear 7, thereby realizing that the auger 3 and the eccentric wheel 12 are driven to rotate at the same time through the transmission shaft 6, and the base plate 4 and the auger 3 are synchronously coordinated and moved.

[0032] In the above embodiment, the close portion on the capstan is periodically fitted with the bottom plate 4 through the rotation of the auger 3, and the bottom plate 4 also forms a periodic reciprocating motion, and the asphalt concrete on the bottom plate 4 is scraped off by the close portion. Since the second rotating shaft 10 of the eccentric wheel 12 of the transmission assembly and the first rotating shaft 9 of the auger 3 are both transmission-connected to the transmission shaft 6, in order to improve the cleaning efficiency of the bottom plate 4, the rotation cycle of the auger 3 is synchronized with the reciprocating motion cycle of the bottom plate 4, that is, each time the close portion on the capstan is fitted with the bottom plate 4, the bottom plate 4 just moves to one side, avoiding the poor cleaning effect caused by the asynchronous movement of the auger 3 and the bottom plate 4.

[0033] Since the bottom plate 4 of the general hopper 2 is a planar structure, but the capstan of the auger 3 is arc-shaped, when the bottom plate 4 is scraped by the capstan, only one area can be scraped, and the entire bottom plate 4 cannot be scraped and cleaned. Therefore, in order to improve the cleaning effect, in one embodiment, the bottom plate 4 is a semi-cylindrical structure with an opening upward, and the axis of the bottom plate 4 is parallel to the axis of the first rotating shaft 9;

[0034] Because the bottom plate 4 is a semi-cylindrical structure, the capstan and the bottom plate 4 can fit completely together when they are in contact, avoiding the existence of cleaning dead corners. At the same time, because the capstan is eccentrically set, the semi-cylindrical structure of the bottom plate 4 is the same as the movement trajectory of the farthest point of the capstan, so that the capstan can fit with the entire semicircular surface of the bottom plate 4 during one rotation.

[0035] Asphalt concrete is placed in the hopper 2, asphalt concrete is easy to enter the connection between the bottom plate 4 and the hopper 2, which may cause the bottom plate 4 to be stuck and thus prevent reciprocating motion. In order to avoid this risk, in one embodiment, grooves are provided at the bottom of the two side walls of the hopper 2 parallel to the first rotating shaft 9, and the two side edges of the bottom plate 4 are respectively slidably sleeved in the grooves at the bottom of the two side walls of the hopper 2;

[0036] That is, the connection between the bottom plate 4 and the hopper 2 wall is at the bottom of the hopper 2 wall, and the side of the bottom plate 4 is inserted into the groove below the hopper 2 wall, so it is difficult for asphalt concrete to enter between the bottom plate 4 and the hopper 2 from the connection below, thereby improving the reliability of the equipment.

[0037] Since the hopper 2 does not bear the weight of the bottom plate 4 in the connection mode between the bottom plate 4 and the hopper 2 in the above embodiment, a connecting piece needs to be provided at the bottom of the hopper 2 to prevent the bottom plate 4 from falling off. Therefore, in one embodiment, cylinders with a diameter greater than the thickness of the bottom plate 4 are provided on both sides of the bottom plate 4, and the axial surface of the cylinder is connected to the side of the bottom plate 4. A circular groove matching the cylindrical body is provided in the groove, and the cylinder and the circular groove cooperate to support the bottom plate 4.

[0038] A cylindrical structure is provided on the two side edges of the bottom plate 4, and there is a circular groove in the groove of the hopper 2. The diameter of the cylindrical structure is greater than the thickness of the bottom plate 4, and the diameter of the circular groove is also greater than the width of the groove. Therefore, during installation, the bottom plate 4 needs to be slid from the side into the circular groove. After the installation is completed, the cylinder and the circular groove form a snap-fit ​​fit, and at the same time can support the bottom plate 4, and the bottom plate 4 on the ground falls off.

[0039] In one embodiment, asphalt concrete is poured into the hopper 2, and the vehicle body 1 is moved forward along the side construction position, and the first rotating shaft 9 and the second rotating shaft 10 are rotated through the transmission shaft 6, so that the auger 3 and the base plate 4 form a synchronous periodic motion. The synchronous periodic motion of the auger 3 and the base plate 4 is used to scrape off the asphalt concrete adhered to the base plate 4.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
