Abstract
Description
Technical Field
[0001] This utility model relates to the field of material metering technology in asphalt production, and in particular to a material metering device for asphalt production. Background Technology
[0002] With the rapid development of road construction and related engineering industries, asphalt, as an important basic material, is crucial in terms of production efficiency and quality control. As a key link in the production process, the material metering device in asphalt production directly affects the accuracy of asphalt proportioning and product quality. In the early days, asphalt production mostly adopted a relatively extensive metering method, which could not meet the strict requirements of modern engineering for asphalt quality. Therefore, high-precision and automated material metering devices have emerged.
[0003] Since weighed materials usually need to be transferred after loading, the efficiency of material transfer and discharge is extremely low when dealing with large quantities of materials, which makes it difficult to meet the needs of continuous and large-scale asphalt production. In addition, during the material transfer and discharge process, materials will inevitably remain on the inner wall of the container, pipes and other parts, resulting in a deviation between the actual amount of material put into production and the measured value. This not only affects the quality stability of asphalt products, but also causes material waste and increases production costs. Utility Model Content
[0004] In order to overcome the problems of existing material metering devices for asphalt production, which often require material transfer after weighing, resulting in large material volume, low discharge efficiency, and material residue in the container, this utility model provides a material metering device for asphalt production.
[0005] The technical solution is as follows: A material metering device for asphalt production includes a weighing and feeding assembly, a support frame, a feeding hopper, and a discharging assembly. A support frame is located at the lower end of the weighing and feeding assembly. A discharging assembly is located in front of the weighing and feeding assembly. The weighing and feeding assembly includes a chassis, a vibrating plate, an electronic weighing plate, a weighing hopper, a baffle bar, springs, and a vibrating motor. Springs are located at the four corners of the lower end of the chassis. The upper and lower ends of the springs are fixedly connected to the chassis and the support frame, respectively. A vibrating plate is located at the upper end of the chassis and is bolted to the chassis. An electronic weighing plate is located at the upper end of the vibrating plate and is fixedly connected to the vibrating plate. A weighing hopper is located at the upper end of the electronic weighing plate and is fixedly connected to the electronic weighing plate. A vibrating motor is located at the rear end of the vibrating plate.
[0006] Furthermore, the weighing hopper is equipped with baffles inside, and the baffles are integrally formed with the weighing hopper.
[0007] Furthermore, a feeding hopper is provided above the weighing and feeding assembly, and the feeding hopper is fixedly connected to the support frame.
[0008] Furthermore, the discharge assembly includes a discharge hopper, a bin door, and a bin door control cylinder; the discharge hopper is located in front of the vibrating plate, and the shell of the discharge hopper is fixedly connected to the support.
[0009] Furthermore, a hopper door is provided at the front end of the discharge hopper, and the hopper door is rotatably connected to the discharge hopper.
[0010] Furthermore, a hopper door control cylinder is installed on the outside of the discharge hopper, and the cylinder body of the hopper door control cylinder is rotatably connected to the discharge hopper.
[0011] Furthermore, the output end of the door control cylinder is rotatably connected to the outer wall of the door.
[0012] The beneficial effects are as follows: This utility model feeds asphalt production materials from the feeding hopper into the weighing hopper. At this time, the electronic weighing plate at the bottom of the weighing hopper weighs the materials. The baffle bar blocks the materials inside the weighing hopper to prevent material overflow and leakage. When the materials reach the set standard weight, the vibration motor is started. The vibration motor drives the vibrating plate, chassis, electronic weighing plate, and weighing hopper to vibrate forward and upward, so that the materials inside the weighing hopper pass over the baffle bar and enter the discharge hopper. Since this vibration discharge method effectively avoids material residue and reduces the difficulty of material discharge, compared with the traditional asphalt processing material weighing equipment, this utility model has a faster feeding speed, less material residue, and lower cleaning difficulty, which greatly improves the feeding efficiency after weighing.
[0013] By setting up the discharge assembly, the discharge hopper receives the material vibrating and thrown out by the weighing hopper, and then, in conjunction with the hopper door control cylinder, controls the opening and closing of the hopper door, thereby realizing the function of precise control of feeding after weighing the material in asphalt production, which greatly improves production efficiency.

The upper and lower ends of 6 are fixedly connected to the chassis 101 and the bracket 2, respectively; the upper end of the chassis 101 is provided with a vibrating plate 102, and the vibrating plate 102 is fixedly connected to the chassis 101 with bolts; the upper end of the vibrating plate 102 is provided with an electronic weighing plate 103, and the electronic weighing plate 103 is fixedly connected to the vibrating plate 102; the upper end of the electronic weighing plate 103 is provided with a weighing hopper 104, and the weighing hopper 104 is fixedly connected to the electronic weighing plate 103; the rear end of the vibrating plate 102 is provided with a vibrating motor 107.
[0023] The weighing hopper 104 is provided with a baffle 105 inside, and the baffle 105 is integrally formed with the weighing hopper 104.
[0024] A feeding hopper 3 is provided above the weighing and feeding assembly 1, and the feeding hopper 3 is fixedly connected to the support 2.
[0025] The asphalt production material is fed from the feeding hopper 3 into the weighing hopper 104. At this time, the electronic weighing plate 103 at the lower end of the weighing hopper 104 weighs the material. The baffle bar 105 blocks the material inside the weighing hopper 104 to prevent the material from overflowing or leaking. When the material reaches the set standard weight, the vibration motor 107 is started. The vibration motor 107 drives the vibrating plate 102, the chassis 101, the electronic weighing plate 103, and the weighing hopper 104 to vibrate forward and upward, so that the material inside the weighing hopper 104 passes over the baffle bar 105 and enters the discharge hopper 401.
