Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture processing technology, and specifically to an asphalt mixture density measuring device. Background Technology

[0002] Asphalt mixtures are composite materials made by mixing aggregates and asphalt binders in appropriate proportions. They are widely used in road construction, such as urban roads and highways. They possess excellent mechanical properties, high-temperature stability, and low-temperature flexibility, are easy to construct, and are recyclable, making them a primary material for constructing high-grade road surfaces.

[0003] Chinese patent discloses an asphalt mixture density measuring device (publication number: CN217638529U). This device adds the mixture to a weighing container through a discharge pipe, then controls an electric valve to quantitatively add the mixture into the weighing container. An electric push rod then moves a scraper to scrape the surface of the weighing container, removing excess mixture from the top, thus ensuring volume accuracy. The density of the mixture is then determined by a weighing sensor. However, this device has the following drawbacks:

[0004] When determining the volume of asphalt mixture, the above-mentioned device continuously feeds asphalt mixture into the weighing container through the discharge pipe. However, during this process, a large gap may be generated between the asphalt mixture and the weighing container, resulting in uneven settling of the mixture and uneven accumulation, which has a significant impact on the measurement results. Therefore, an asphalt mixture density measuring device is proposed to solve the above problems. Utility Model Content

The feeding mechanism 1 includes a cylinder 106, a first motor 110, a weight sensor 117, and a second motor 118. The feeding mechanism 1 includes a base plate 101, with support rods 102 fixedly connected to both sides of the top of the base plate 101. A support frame 109 is fixedly connected to the top of the two support rods 102. A turntable 112 is rotatably connected to the upper inner side of the support frame 109. Lifting rods 114 are symmetrically slidably connected to the top surface of the turntable 112. A support ring 116 is fixedly connected to the top of the two lifting rods 114. Support springs 115 are fixedly connected to both sides of the bottom surface of the support ring 116, and the bottoms of the two support springs 115 are fixedly connected to the top of the turntable 112. The weight sensor 117 is fixedly connected to the middle of the top surface of the support ring 116. Figures 1-2 As shown, after the support ring 116 is moved by force, the support spring 115 drives the support ring 116 to vibrate continuously, thereby improving the uniformity of the mixture in the weighing container 2.

[0029] One end of the bottom surface of the support frame 109 is fixedly installed to the motor 110. The output shaft of the motor 110 is located inside the support frame 109, and a gear 111 is fixedly connected to the top of the output shaft of the motor 110. A ring rack 113 is meshed with the outer side of the gear 111. The top surface of the ring rack 113 is fixedly connected to the bottom of the turntable 112. Figures 2-3 As shown, gear 111 pushes the inner side of ring rack 113, thereby driving turntable 112 to rotate within support frame 109;

[0030] Vertical cylinders 103 are fixedly connected to the top surface of the base plate 101 and to the outer side of each support rod 102. The middle of one vertical cylinder 103 is fixedly connected to a second motor 118. A cam 119 is also fixedly connected to the output shaft of the second motor 118. The side of the cam 119 is in movable contact with the bottom surface of the support ring 116. Figures 1-4 As shown, when the cam 119 rotates continuously, it drives the support ring 116 to reciprocate up and down.

[0031] Both vertical cylinders 103 have telescopic rods 104 slidably connected to their inner walls. The top ends of both telescopic rods 104 are fixedly connected to a top plate 105. The outer surface of one vertical cylinder 103 is fixedly connected to a cylinder 106, and the top of the extended end of the cylinder 106 is fixedly connected to the bottom of the top plate 105. A storage box 107 is fixedly installed in the middle of the top surface of the top plate 105. A conveying pipe 108 is connected to the bottom of the storage box 107 and extends to the bottom of the top plate 105. A control valve is installed inside the conveying pipe 108. Figure 1 As shown, by intermittently opening and closing the control valve, the material conveying pipe 108 feeds materials into the container body 201 in batches;

[0032] The weighing container 2 includes a container body 201. A lower support ring 202 is fixedly connected to the middle of the outer wall of the container body 201, and an upper support ring 203 is fixedly connected to the upper end of the outer wall of the container body 201. A collection hopper 204 is sleeved on the top of the container body 201, and the bottom surface of the collection hopper 204 is in movable contact with the top surface of the upper support ring 203. The container body 201 is fully connected to the support ring 116, the turntable 112, and the support frame 109. The bottom surface of the lower support ring 202 abuts against the weight sensor 117. Figure 1 As shown, the container body 201 is made of plastic and is used as a disposable item.

[0033] The working principle of this utility model:

[0034] When the device is in use, the cylinder 106 pushes the top plate 105 upward, so that the container body 201 can be inserted into the inner side of the support ring 116. The lower support ring 202 rests on the weight sensor 117 to complete the support and fixation. The cylinder 106 drives the top plate 105 to reset and opens the internal control valve of the conveying pipe 108. The mixed material in the storage box 107 is fed into the container body 201 in batches. After each feeding, the motor 118 can be started to drive the cam 119 to rotate continuously, so that the support ring 116 is pushed up and down, and the lifting rod 114 slides up and down on the inner wall of the turntable 112. Secondly, when the motor 110 is started, the gear 111 can drive the ring rack 113 and the turntable 112 to rotate, thereby driving the support ring 116 and the container body 201 to rotate, thus helping the mixed material to be evenly distributed in the container.

[0035] After the container body 201 is filled with the mixture, the operator uses a shovel to push the excess mixture on top of the container body 201 into the collection hopper 204. Finally, the collection hopper 204 is removed upwards, and the weight of the container body 201 and the mixture inside is measured by the weight sensor 117.

[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
