Description

Technical Field

[0001] The utility model relates to the technical field of scraper devices of conveyor vehicles, in particular to a scraper device of a conveyor belt and a conveyor vehicle. Background Art

[0002] During asphalt paving, a feed truck is used to transport material from trucks to the paver after secondary mixing. Asphalt adhering to the feed truck's belt can be removed by scraping with a scraper. However, due to its considerable viscosity, asphalt eventually transfers from the belt to the scraper, where it accumulates, affecting the scraping effect. When the asphalt accumulates to a certain volume, the force of gravity on the sticky asphalt clumps exceeds the adhesion of the asphalt to the scraper surface. The sticky asphalt clumps will fall off the scraper and onto the ground, forming large spots of asphalt grease. During the subsequent paving process, after being covered with the asphalt mixture and compacted by a roller, the asphalt grease content is higher than that in other areas of normal paving material, resulting in poor material uniformity and the appearance of asphalt oil spots on the paved surface, making for an unsightly appearance.

Therefore, the above description should not be considered as limiting, but merely as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0031] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0032] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0033] It should also be understood that although the present application has been described with reference to certain specific examples, those skilled in the art will readily be able to implement many other equivalent forms of the present application.

[0034] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0035] Specific embodiments of the present application will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to variously utilize the present application with substantially any suitable detailed structure.

[0036] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0037] To address the problems described in the background art, the present invention discloses a scraper device for a conveyor belt, which can be used with a conveyor truck. The conveyor truck includes a conveyor belt. The conveyor truck, as a type of conveying equipment, can be used to transport material from a truck to a paver after secondary mixing during asphalt paving. The scraper device can scrape off asphalt adhering to the conveyor belt of the conveyor truck. The following example illustrates the scraper device scraping off asphalt from a conveyor belt used to transport asphalt.

[0038] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The scraper device includes a first bracket 1, a second bracket 2, a scraper assembly 3 and a heating mechanism 4.

[0039] The first bracket 1 and the second bracket 2 can serve as a mounting base for the scraper assembly 3 and the heating mechanism 4 .

[0040] The scraper assembly 3 is disposed between the first bracket 1 and the second bracket 2. The scrapers of the scraper assembly 3 are used to scrape material off the conveyor belt. Specifically, one end of the scraper assembly 3 is disposed on the first bracket 1, and the other end of the scraper assembly 3 is disposed on the second bracket 2. The scraper assembly 3 can be provided with multiple scrapers, which can be spaced sequentially from the first bracket 1 toward the second bracket 2. The multiple scrapers scrape the asphalt off the conveyor belt, allowing it to separate from the conveyor belt and preventing it from adhering to the conveyor belt and affecting material transport. Some of the asphalt scraped from the conveyor belt will adhere to the scrapers.

[0041] The heating mechanism 4 is mounted on the scraper assembly 3 and is designed to heat the scraper blades of the scraper assembly 3 to remove any asphalt adhering to them. Specifically, because asphalt has a certain adhesive property, if it is not heated, asphalt will accumulate on the scraper blades, forming large clumps. When the asphalt clumps accumulate to a certain level, gravity forces them to fall from the scraper blades onto the ground, forming large greasy spots that affect the quality and aesthetics of the road surface. To prevent this, the heating mechanism 4 heats the scraper blades while they are scraping asphalt off the conveyor belt. Heating the asphalt on the scraper blades reduces its adhesion to the scraper blades, making it easier to remove. Therefore, heating the asphalt on the scraper blades prevents the accumulation of large clumps of asphalt. Instead, asphalt will fall off the scraper blades when less asphalt adheres to them. Compared with larger pieces of asphalt sticky blocks, the asphalt that falls to the ground after heating, even if it falls to the ground in the form of sticky blocks, has significantly less impact on the ground and less adverse effects on the quality and aesthetics of the road surface.

[0042] The embodiment of the present application sets a heating mechanism 4 at the scraper position of the scraper assembly 3 to heat the scraper, thereby enabling it to heat the asphalt material on the scraper, reduce the viscosity of the asphalt, and reduce the adhesion performance of the asphalt, so that the asphalt blocks accumulated on the scraper can fall off the scraper in a very small state, thereby improving the cleaning effect of the scraper device on the conveyor belt, and avoiding the problem of large asphalt spots on the road surface caused by the falling of large asphalt blocks, thereby improving the construction effect and improving the quality and aesthetics of the road surface.

[0043] In some embodiments, the scraper assembly 3 includes a first scraper assembly 32 3 and a second scraper assembly 34 3 , and the first scraper assembly 32 3 and the second scraper assembly 34 3 are arranged in parallel. The first scraper assembly 32 3 and the second scraper assembly 34 3 can respectively scrape asphalt from the parallel parts of the conveyor belt, thereby improving the cleaning efficiency of the asphalt on the conveyor belt.

[0044] The heating mechanism 4 includes a first heating mechanism 4 and a second heating mechanism 4. The first heating mechanism 4 is provided on the first scraper assembly 32 to heat the scraper of the first scraper assembly 32, thereby heating asphalt adhering to the scraper of the first scraper assembly 32 and making it easier to separate from the scraper. The second heating mechanism 4 is provided on the second scraper assembly 34, thereby heating the scraper of the second scraper assembly 34 and making it easier to separate from the scraper. The first and second heating assemblies can be activated simultaneously or separately according to production needs.

[0045] In some embodiments, one end of the first heating mechanism 4 and one end of the second heating mechanism 4 extend outward from one end of the first bracket 1 or the second bracket 2, and the end extending out of the first bracket 1 or the second bracket 2 is connected to a power source. The power source provides electrical energy to the first heating mechanism 4 and the second heating mechanism 4, which convert the electrical energy into thermal energy, enabling the first heating mechanism 4 and the second heating mechanism 4 to electrically heat the scraper. When the scraper is heated, the asphalt adhering to the scraper melts, allowing it to separate more quickly from the scraper.

[0046] The power supply can be provided by the generator of the feed truck, or a separate power supply can be provided on the scraper device. For example, a rechargeable power supply can be provided on the scraper device, which can be charged by the generator of the feed truck or by other means. The first heating mechanism 4 and the second heating mechanism 4 can share a power supply or be connected to separate power supplies. The specific configuration can be adjusted according to actual production needs. This is merely an example and does not limit the scope of protection of the claims.

[0047] In some embodiments, the first scraper 32 assembly 3 includes a first mounting long plate 31 and a first scraper 32, and a scraper 35 is provided at one end of the first scraper 32. The second scraper 34 assembly 3 includes a second mounting long plate 33 and a second scraper 34, and a scraper 35 is also provided at one end of the second scraper 34.

[0048] At least two first scrapers 32 are provided on the first mounting plate 31, and at least two second scrapers 34 are provided on the second mounting plate 33. The number of the first scrapers 32 and the second scrapers 34 can be reasonably set according to the length of the conveyor belt and the width of the scrapers, and is not specifically limited here.

[0049] One end of the first scraper 32 provided with a scraper 35 can be detachably fixed to the first mounting long plate 31, and one end of the second scraper 34 provided with a scraper 35 can be detachably fixed to the second mounting long plate 33. For example, one end of the first scraper 32 provided with a scraper 35 can be detachably fixed to the first mounting long plate 31 by a screw, and one end of the second scraper 34 provided with a scraper 35 can be detachably fixed to the second mounting long plate 33 by a screw.

[0050] The first heating mechanism 4 is in direct or indirect contact with one end of the first scraper 32 where the scraper 35 is provided, so as to heat the scraper 35 on the first scraper 32. The second heating mechanism 4 is in direct or indirect contact with one end of the second scraper 34 where the scraper 35 is provided, so as to heat the scraper 35 on the second scraper 34.

[0051] For example, the first heating mechanism 4 can be fixed to the first mounting plate 31 via a fixed structure. The fixed structure contacts the first heating mechanism 4 and one end of the first scraper 32 provided with the scraper 35. The fixed structure can conduct heat, thereby transferring the heat energy generated by the first heating mechanism 4 to the scraper 35 of the first scraper 32, thereby achieving indirect contact between the first heating mechanism 4 and the end of the first scraper 32 provided with the scraper 35. Alternatively, the first heating mechanism 4 can be placed against the end of the first scraper 32 provided with the scraper 35, directly transferring heat to the scraper 35 on the first scraper 32, thereby achieving direct contact between the first heating mechanism 4 and the end of the first scraper 32 provided with the scraper 35. The second heating mechanism 4 can be configured in the same manner as the first heating mechanism 4.

[0052] Combine Figure 5 The fixing structure may include a metal strip 51 and fixing bolts 52. The metal strip 51 is pressed against the first heating mechanism 4, and the metal strip and the first heating mechanism 4 are fixed to the first mounting long plate 31 by the fixing bolts 52. Of course, the first heating mechanism 4 may also be fixed by other fixing structures.

[0053] Continuing with the example of the first heating mechanism 4 and the first mounting plate 31, the first mounting plate 31 can be a bent plate, that is, the first mounting plate 31 forms a bent space, and the first heating mechanism 4 can be fixed within the bent space by a fixing structure. This protects the first heating mechanism 4 through the bent space of the first mounting plate 31, preventing the first heating mechanism 4 from being damaged by impact, etc., and also preventing construction workers from touching the first heating mechanism 4 and causing personal injury. Of course, the first mounting plate 31 can also be configured as a tube, with a portion of the first heating mechanism 4 disposed within the space within the tube.

[0054] In some embodiments, combined Figure 5The first heating mechanism 4 includes a first heating rod 41, which is arranged along the length direction of the first mounting long plate 31, and the width direction of the first scraper 32 is set along the length direction of the first mounting long plate 31, and the first heating rod 41 can completely cover the first scraper 32 along the width direction of the first scraper 32, so as to maximize the heating of the first scraper 32 and the scraper 35 on the first scraper 32 by the first heating rod 41, improve the heating effect, and thereby improve the separation efficiency and cleaning effect of the asphalt on the scraper 35.

[0055] Similar to the arrangement of the first heating rod 41, the second heating mechanism 4 includes a second heating rod 42. The second heating rod 42 is arranged along the length of the second mounting plate 33. The width of the second scraper 34 is arranged along the length of the second mounting plate 33. The second heating rod 42 can completely cover the second scraper 34 along the width of the first scraper 32. The effect is similar to that of the first heating rod 41 and will not be repeated here.

[0056] In some embodiments, the heating power of the heating mechanism 4 matches the thermal power required to remove the material from the scraper. That is, the heating power of the heating mechanism 4 matches the thermal power required to remove the asphalt clumps after they have accumulated. Alternatively, the heating power of the heating mechanism 4 may be set slightly higher to maximize the asphalt cleaning effect.

[0057] In some embodiments, the scraper assembly further includes a controller, to which the heating mechanism 4 is connected, and which is configured to control the on / off operation of the heating mechanism 4. The controller can be mounted directly on the scraper assembly, for example, on the first bracket 1 or the second bracket 2, or can be located directly within the cab of the feed truck. When the feed conveyor belt does not need to be cleaned, the controller can send a control signal to the heating mechanism 4 to stop heating, and upon receipt of this control signal, the heating mechanism 4 will stop heating. Similarly, when the feed conveyor belt needs to be cleaned, the controller can send a control signal to the heating mechanism 4 to start heating, and upon receipt of this control signal, the heating mechanism 4 will begin heating.

[0058] The present application also provides a feed truck comprising a scraper assembly as described in any of the above embodiments. The scraper assembly provides a better cleaning of the feed truck's conveyor belt, improving the feed truck's efficiency. Furthermore, asphalt on the feed truck's conveyor belt does not accumulate into large, sticky clumps that fall onto the road surface, thereby improving the quality of the feed truck's construction and the quality and aesthetics of the road surface.

[0059] The above describes in detail several embodiments of the present invention, but the present invention is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of the present invention, and these variations and modifications should fall within the scope of protection claimed by the present invention.
