DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0024] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] Embodiment

[0026] Reference Figures 1-4 For the embodiment of the present application, the embodiment provides a gap filling machine asphalt discharging valve, comprising,

[0027] The storage assembly 100 comprises a support 101, a tank 102 fixedly connected to the end of the support 101, a tank cover 103 adaptively installed on the top of the tank 102, and a feed pipe 104 encapsulated on the top of the tank cover 103, the feed pipe 104 being in communication with the inside of the tank cover 103;

[0028] The discharging assembly 200 comprises a guide pipe 201 fixedly connected to the bottom of the tank 102, a guide cover 202 fixedly connected to the end of the guide pipe 201, a sliding block 203 slidingly installed in the inside of the guide pipe 201, and a scraper 204 hingedly connected to the side wall of the sliding block 203, the scraper 204 being slidingly inserted into the inner wall of the guide pipe 201.

[0029] The support 101 is used as a whole support frame, the material box 102 is fixed to the top end of the support 101 and is used for storing bitumen to be processed. The box cover 103 is used for sealing the material box 102 and reducing bitumen vapor leakage. The feeding pipe 104 is used for rapid filling of bitumen raw materials. The guide pipe 201 is connected to the bottom of the material box 102, facilitating the guiding of bitumen discharging. The guide cover 202 is used for expanding the range of bitumen discharging, facilitating the crack pouring operation. The sliding block 203 is connected with the scraper 204, and the scraper 204 is moved by the sliding block 203, facilitating the scraping of bitumen materials in the material box 102, and maintaining the discharging efficiency.

[0030] Specifically, the discharging assembly 200 further comprises a guide rod 205 fixedly connected to the side wall of the scraper 204, the end of the guide rod 205 is inserted into the side wall of the sliding block 203, the discharging assembly 200 further comprises a first spring 206 fixedly connected to the inside of the sliding block 203, and the end of the first spring 206 is fixedly connected to the end of the guide rod 205.

[0031] The guide rod 205 is used in cooperation with the first spring 206 to maintain the position of the scraper 204 when the sliding block 203 advances, facilitating the scraping of materials. When the sliding block 203 retracts, the materials will press the scraper 204, so that the scraper 204 is attached to the side wall of the sliding block 203. When the sliding block 203 moves to the end of the guide pipe 201 and stops, the scraper 204 will be lifted from the side wall of the sliding block 203 under the elastic force provided by the first spring 206, facilitating the next scraping operation.

[0032] Further, the discharging assembly 200 further comprises a hydraulic rod 207 fixedly connected to the bottom side wall of the guide pipe 201, and the output shaft of the hydraulic rod 207 penetrates the side wall of the guide pipe 201 and is fixedly connected to the end of the sliding block 203.

[0033] The hydraulic rod 207 is used for driving the sliding block 203 to reciprocate, and the materials are scraped in a cycle, so as to maintain the discharging efficiency of the materials.

[0034] Preferably, the discharging assembly 200 further comprises an insertion block 208 sealingly inserted into the inside of the guide pipe 201, the end side wall of the insertion block 208 is provided with an insertion groove structure used in cooperation with the end inclined surface of the sliding block 203, the discharging assembly 200 further comprises a second spring 209 fixedly connected to the inner wall of the guide pipe 201, and the end of the second spring 209 is fixedly connected to the inner wall of the insertion block 208.

[0035] The insert block 208 is a wedge-shaped block and is horizontally slidably installed in the groove on the inner wall of the guide pipe 201, and the inclined surface is matched with the inclined surface on the end of the sliding block 203; the second spring 209 is fixed to the inner side of the insert block 208 and provides a horizontal thrust force, so that the insert block 208 is always in contact with the sliding block 203; during the process that the sliding block 203 moves to the end of the guide pipe 201 and gradually stops, the second spring 209 is slowly compressed, so that the insert block 208 shrinks towards the inner wall of the guide pipe 201, the scraper 204 gradually approaches the inner wall of the guide pipe 201, and the material between the inner wall of the guide pipe 201 and the scraper 204 is pushed backward to prevent the material from blocking and affecting the scraping precision; when the scraper 204 moves to a position away from the insert block 208, the second spring 209 releases the elastic potential energy stored during the compression, and the insert block 208 is ejected, at this time, the remaining material in the gap is also pushed forward, which is convenient for the next scraping operation.

[0036] Preferably, the discharging assembly 200 further comprises a sealing plate 210 which is inserted and sealed at the bottom of the guide cover 202, and the end of the sealing plate 210 is bolted to the outer side wall of the guide cover 202 through a handle.

[0037] The sealing plate 210 is connected to the bottom flange of the guide cover 202 through a handle bolt, which is used to close the discharge port when the machine is stopped.

[0038] In use, the sealing plate 210 is fixed to the bottom of the guide cover 202 through a handle bolt to close the discharge port; the sliding block 203 is in the initial position of the hydraulic rod 207, and the scraper 204 is attached to the inner wall of the guide pipe 201; the handle bolt is loosened and the sealing plate 210 is removed; the hydraulic rod 207 is energized to extend and push the sliding block 203 to move downward along the guide pipe 201, and the scraper 204 moves downward synchronously to open the channel between the material box 102 and the guide pipe 201; the molten asphalt flows into the guide pipe 201 under the action of gravity and is uniformly extruded by the scraper 204; during the operation, the guide rod 205 is always attached to the inner wall of the guide pipe 201 under the action of the first spring 206 when the scraper 204 moves with the sliding block 203, which ensures uniform scraping and avoids asphalt retention. The hydraulic rod 207 is retracted to move the sliding block 203 upward, and the scraper 204 will be attached to the side wall of the sliding block 203 due to the material pressure, which ensures smooth movement of the sliding block 203. The above steps are repeated to perform the discharging operation; after the discharging is completed, the sealing plate 210 is installed and the handle bolt is tightened to complete the sealing of the discharge port.

[0039] In summary, the hydraulic rod 207 drives the sliding block 203 to cooperate with the scraper 204 to control the asphalt discharge flow within a specified range, ensuring stable flow during operation. The scraper 204 is always attached to the inner wall of the guide pipe 201 through the first spring 206, and can scrape off the asphalt adhered to the pipe wall when the sliding block 203 reciprocates, which reduces material waste and cleaning frequency.
