Description

Technical Field

[0001] This utility model relates to the field of asphalt batching technology, and in particular to an asphalt aggregate batching device with an adjustable feed inlet. Background Technology

[0002] In the complex and crucial process of asphalt pavement construction, it is necessary to accurately control the mixing ratio of various materials. Asphalt and different types and specifications of aggregates, such as limestone, basalt, and granite, must be mixed and stirred according to a specific formula. This precise ratio aims to prepare high-performance asphalt concrete, ensuring that it has good compressive strength, wear resistance, skid resistance, and low-temperature crack resistance, so as to meet the requirements of different traffic volumes, climatic conditions, and pavement use.

[0003] Existing asphalt aggregate batching devices have some problems in the feeding process. The batching device cannot flexibly adjust the size of the feed inlet, making it difficult to guarantee the feeding ratio of different types of aggregates, which in turn affects the quality stability of asphalt concrete. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: the batching device cannot flexibly adjust the size of the feed inlet, making it difficult to guarantee the feeding ratio of different types of aggregates, which in turn affects the quality stability of asphalt concrete. Therefore, this invention proposes an asphalt aggregate batching device with an adjustable feed inlet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable feed port asphalt aggregate batching device includes a mixing drum, a rectangular feed pipe installed at the upper end of the mixing drum, a hopper fixedly installed at the upper end of the feed pipe, and multiple partitions fixedly installed inside the feed pipe and the hopper, the multiple partitions dividing the feed pipe and the hopper into multiple hoppers;

[0007] The feed pipe has multiple movable holes on its side that are connected to multiple hoppers. Each of the movable holes has a blocking plate that is horizontally slidably installed. One end of the blocking plate is slidably inserted into the hopper. A movable block is fixedly installed on the lower surface of the blocking plate. A threaded rod is horizontally rotatably installed on the side of the feed pipe. An adjusting block is fixedly installed on one end of the threaded rod. The movable block is threadedly sleeved on the threaded rod.

[0008] Preferably, the feed pipe has a rectangular hole on its side that communicates with the moving hole, and a guide block with a right-angled trapezoidal longitudinal section is fixedly installed on the upper surface of the plug plate. The guide block is slidably inserted into the rectangular hole, and the inclined end of the guide block is inserted into the hopper. A sealing assembly is provided in the rectangular hole.

[0009] Preferably, an installation groove is provided on the upper inner wall of the rectangular hole, and a sealing plate is vertically slidably installed in the installation groove by means of multiple telescopic springs, with the lower end of the sealing plate slidingly contacting the inclined surface of the guide block.

[0010] Preferably, a rotating shaft is horizontally rotatably mounted on the feed pipe, the rotating shaft passes through multiple hoppers, a drive motor is fixedly mounted on the side of the feed pipe, the output shaft of the drive motor is fixedly connected to one end of the rotating shaft, and each of the multiple hoppers is equipped with a mixing component for mixing aggregates.

[0011] Preferably, the stirring assembly includes a fixed sleeve fixedly fitted onto the rotating shaft and a plurality of stirring blades circumferentially and equidistantly fixedly installed on the side of the fixed sleeve.

[0012] Preferably, a sealing gasket is fixedly installed on the lower surface of the blocking plate, and the sealing gasket makes sealing sliding contact with the inner wall of the moving hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The lower end of the silo is the feed inlet of the batching device. When it is necessary to adjust the size of the feed inlet, the adjusting block can be rotated to drive the threaded rod to rotate. The threaded rod drives the blocking plate to move in the moving hole through the moving block, thereby realizing the adjustment of the size of the feed inlet. The size of each feed inlet is in a certain proportion with the feeding ratio of each aggregate, thereby ensuring the feeding ratio of different types of aggregates and improving the quality stability of asphalt concrete.

[0015] 2. During the feeding process, the drive motor, rotating shaft and fixed sleeve drive multiple mixing blades to rotate in the hopper to prevent aggregate from accumulating and blocking the feed inlet. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 An adjustable feed inlet asphalt aggregate batching device includes a mixing tank 1, a rectangular feed pipe 2 installed at the upper end of the mixing tank 1, a hopper 3 fixedly installed at the upper end of the feed pipe 2, and multiple baffles 4 fixedly installed inside the feed pipe 2 and the hopper 3. The multiple baffles 4 divide the feed pipe 2 and the hopper 3 into multiple silos 5. The lower end of the silo 5 is the feed inlet of the batching device. The baffles 4 divide the feed pipe 2 and the hopper 3 into multiple silos 5, which can be used to feed different types of aggregates and avoid aggregate blockage caused by contact and adhesion of different aggregates during the feeding stage.

[0024] The feed pipe 2 has multiple movable holes on its side that are connected to multiple hoppers 5. Each movable hole has a horizontally sliding block 6 installed in it. One end of the block 6 is slidably inserted into the hopper 5. A movable block 7 is fixedly installed on the lower surface of the block 6. A threaded rod 8 is horizontally rotatably installed on the side of the feed pipe 2. An adjusting block 9 is fixedly installed on one end of the threaded rod 8. The movable block 7 is threadedly sleeved on the threaded rod 8.

[0025] One end of the blocking plate 6 is slidably inserted into the hopper 5, and the side of the blocking plate 6 is in sealed sliding contact with the inner wall of the hopper 5. When it is necessary to adjust the size of the feed inlet, the adjusting block 9 is rotated to drive the threaded rod 8 to rotate. During the rotation of the threaded rod 8, the blocking plate 6 can be moved back and forth in the moving hole through the moving block 7. When the blocking plate 6 moves into the hopper 5, the feed inlet becomes smaller. When the blocking plate 6 moves out of the hopper 5, the feed inlet becomes larger, thereby realizing the adjustment of the size of multiple feed inlets. The size of each feed inlet is in a certain proportion with the feeding ratio of each aggregate, thereby ensuring the feeding ratio of different types of aggregates and improving the quality stability of asphalt concrete.

[0026] A rectangular hole communicating with the moving hole is opened on the side of the feed pipe 2. A guide block 10 with a right-angled trapezoidal longitudinal section is fixedly installed on the upper surface of the block plate 6. The guide block 10 is slidably inserted into the rectangular hole. The inclined end of the guide block 10 is inserted into the hopper 5. A sealing component is provided in the rectangular hole. An installation groove is opened on the upper inner wall of the rectangular hole. A sealing plate 12 is vertically slidably installed in the installation groove through multiple telescopic springs 11. The lower end of the sealing plate 12 slides in contact with the inclined surface of the guide block 10.

[0027] When the telescopic spring 11 is in a compressed state, under the action of the elastic force of the telescopic spring 11, the lower end of the sealing plate 12 contacts the inclined surface of the guide block 10, thereby preventing the aggregate in the hopper 5 from flowing out of the rectangular hole. During the feeding process, the inclined surface of the guide block 10 can play a reverse flow role, causing the aggregate to move towards the gap between the block plate 6 and the hopper 5.

[0028] A rotating shaft 13 is horizontally rotatably mounted on the feed pipe 2. The rotating shaft 13 passes through multiple hoppers 5. A drive motor 14 is fixedly mounted on the side of the feed pipe 2. The output shaft of the drive motor 14 is fixedly connected to one end of the rotating shaft 13. Each of the multiple hoppers 5 is equipped with a mixing assembly for mixing aggregates. The mixing assembly includes a fixed sleeve 15 fixedly sleeved on the rotating shaft 13 and multiple mixing blades 16 circumferentially and equidistantly fixed on the side of the fixed sleeve 15.

[0029] During the feeding process, the drive motor 14 is started, which drives the rotating shaft 13 to rotate. The rotating shaft 13 then drives multiple fixed sleeves 15 to rotate in multiple hoppers 5. When the fixed sleeves 15 rotate, they will drive multiple mixing blades 16 to rotate around the rotating shaft 13 in the hopper 5, thus preventing aggregate from accumulating and blocking the feed inlet.

[0030] A sealing gasket is fixedly installed on the lower surface of the blocking plate 6. The sealing gasket makes a sealing sliding contact with the inner wall of the moving hole. The sealing gasket ensures the sealing between the blocking plate 6 and the moving hole, preventing the aggregate from overflowing during the feeding process.

[0031] In this invention, when it is necessary to adjust the size of the feed inlet, rotating the adjusting block 9 drives the threaded rod 8 to rotate. During the rotation of the threaded rod 8, the moving block 7 can drive the blocking plate 6 to move back and forth in the moving hole. When the blocking plate 6 moves into the hopper 5, the feed inlet becomes smaller; when the blocking plate 6 moves out of the hopper 5, the feed inlet becomes larger. This allows for the adjustment of the size of multiple feed inlets. The size of each feed inlet is in a certain proportion to the feeding ratio of each aggregate, thereby ensuring the feeding ratio of different types of aggregates and improving the quality stability of asphalt concrete.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
