[0002] Asphalt pavement is widely used in the construction of medium and high-grade highways in my country due to its good driving comfort and excellent performance. The raw material for asphalt pavement is asphalt mixture, which is a composite material produced by putting various aggregates into the asphalt mixing plant according to a certain ratio and uniformly mixing with asphalt through a series of processing procedures. In the process of continuous production of the asphalt mixing plant, the hot material bin often overflows due to unstable aggregate quality, unreasonable hot material screen size, mismatch between target and production mix ratio, etc., resulting in reduced mixing production efficiency, waste of raw materials, poor quality of mixture gradation, etc. The management of the mixing station often improves the control of raw material quality and variability, controls the flow calibration of the cold material bin, and reasonably adjusts the screen size to reduce the overflow phenomenon. However, from the actual engineering experience, in the actual mixing process, there are multiple pieces of sand and gravel squeezed together to cause temporary blockage, which changes the feeding speed of the feed port, and then causes overflow problems at the feed port. In the face of such emergencies, there is no good solution in the existing technology. Utility Model Content

[0023] Specifically, the utility model achieves the purpose of extending the length of the mixed feed pipe 1 by providing a feed sleeve 3, a gear 9, and a discharge mechanism 6, thereby avoiding overflow of the mixed material, reserving sufficient feed space, and then solving the overflow problem caused by temporary blockage caused by sand and gravel extrusion, greatly reducing the overflow of the mixed material, thereby reducing the cost of overflow material processing.

[0024] In another embodiment of the present invention, reference Figures 1 to 3, an overflow bin of an asphalt mixing plant, comprising: a mixed feed pipe 1, an overflow bin 2 is fixedly sleeved outside the mixed feed pipe 1, a feed sleeve 3 is slidably sleeved outside the mixed feed pipe 1, a protective box 4 is fixedly connected to the mixed feed pipe 1, a gear 9 is arranged in the protective box 4, a discharge mechanism 6 is slidably arranged in the overflow bin 2, a first rack 32 is fixedly connected to the bottom end of the feed sleeve 3, the first rack 32 passes through the protective box 4 and meshes with the gear 9, the top of the discharge mechanism 6 passes through the protective box 4 and meshes with the gear 9, the lower end of the overflow bin 2 is fixedly connected to the discharge bin 5, the discharge mechanism 6 includes a trapezoidal block 61, the trapezoidal block 61 is slidably arranged in the discharge bin 5, and the top of the trapezoidal block 61 is fixedly connected to the second rack 6 2, the second rack 62 is meshed with the gear 9, the bottom end of the trapezoidal block 61 is connected to the inner wall of the discharge bin 5 through the first spring 63, the inner cavity bottom surface of the overflow bin 2 is inclined to the discharge bin 5, and the top of the trapezoidal block 61 is an inclined surface, a bin door 7 is rotatably provided on the overflow bin 2, a locking mechanism 8 is provided in the discharge bin 5, and the rotation of the bin door 7 is limited by the locking mechanism 8, the locking mechanism 8 includes a slider 81, a slide groove 51 is provided in the discharge bin 5, the slider 81 is slidably provided in the slide groove 51, the slider 81 is connected to the inner wall of the slide groove 51 through the second spring 83, the top of the slider 81 is fixedly connected with a wedge block 82, the lower end of the trapezoidal block 61 is fixedly connected with a vertical plate 64, and the vertical plate 64 is located above the slider 81.

[0025] Specifically, a gear 9 is rotatably arranged in the protective box 4, one end of the first spring 63 is fixedly connected to the bottom end of the trapezoidal block 61, and the other end of the first spring 63 is fixedly connected to the inner wall of the discharge bin 5. The bottom of the inner cavity of the overflow bin 2 is an inclined surface, and the discharge bin 5 is at the lowest point. The mixed materials dropped into the overflow bin 2 will slide toward the discharge bin 5 and squeeze the trapezoidal block 61, so that the trapezoidal block 61 overcomes the elastic force of the first spring 63 and slides downward. When the vertical plate 64 squeezes the sliding block 81, the sliding block 81 overcomes the elastic force of the second spring 83 and slides downward. Here, one end of the second spring 83 is fixedly connected to the inner wall of the slide groove 51, and the other end is fixedly connected to the bottom end of the sliding block 81, and then the wedge block 82 slides downward and no longer abuts the bin door 7. Since the top end of the trapezoidal block 61 is an inclined surface, the bin door 7 rotates under the gravity of a large amount of mixed materials, and the mixed materials are discharged through the gap opened by the bin door 7, thereby realizing the automatic discharge of the mixed materials in the overflow bin 2, which greatly reduces the labor cost.

[0026] Furthermore, a counterweight block 31 is fixedly connected to the outside of the feed sleeve 3 , and the counterweight block 31 is located directly above the protection box 4 .

[0027] Specifically, refer to Figure 1 and Figure 2By setting the counterweight block 31, on the one hand, the counterweight block can facilitate the rotation of the gear 9 to drive the feed sleeve 3 to slide vertically upward. On the other hand, it can block the mixture overflowing from the feed sleeve 3 to prevent the mixture from damaging the first rack 32.

[0028] In this utility model, reference is made to Figures 1 to 3 First, the mixture overflows from the mixing feed pipe 1 and falls into the overflow bin 2, and then the mixture slides to the top of the trapezoidal block 61. Under the gravity of the mixture, the trapezoidal block 61 overcomes the elastic force of the first spring 63 and slides downward, and then the second rack 62 drives the gear 9 to rotate counterclockwise, so that the first rack 32 slides upward, and the feeding sleeve 3 slides upward over the top of the mixing feed pipe 1, so that the feeding space of the mixing feed pipe 1 is expanded, and then the overflow problem caused by temporary blockage caused by sand and gravel extrusion is solved, and the overflow amount of the mixture is greatly reduced, thereby reducing the cost of overflow material processing. When the mixture in the discharge bin 5 accumulates to a certain extent, the vertical plate 64 squeezes the slider 81, and the slider 81 overcomes the elastic force of the second spring 83 and slides downward, and then the wedge block 82 slides downward and no longer resists Connect to the bin door 7. Since the top of the trapezoidal block 61 is an inclined surface, the bin door 7 rotates under the gravity of a large amount of mixed material, and the mixed material is discharged through the gap opened by the bin door 7, thereby realizing the automatic discharge of the mixed material in the overflow bin 2, greatly reducing the labor cost. At the same time, as the mixed material on the top of the trapezoidal block 61 gradually decreases, the elastic force of the first spring 63 slowly lifts the trapezoidal block 61, and the trapezoidal block 61 drives the gear 9 to rotate clockwise, and the gear 9 drives the feeding sleeve 3 to slide downward. Finally, when the mixed material on the trapezoidal block 61 is discharged, the bin door 7 rotates counterclockwise under the action of gravity, and squeezes the inclined surface of the slider 81, and blocks the discharge port after overcoming the elastic force of the second spring 83. Then the slider 81 returns to its original position under the elastic force of the second spring 83, and then enters the next cycle.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
