Description

Technical Field

[0001] The utility model relates to the technical field of asphalt processing equipment, in particular to an asphalt mixing plant. Background Art

[0002] Asphalt mixing plants are key equipment for preparing asphalt mixtures. Their main function is to mix aggregate and asphalt in a certain proportion and heat and stir them to make asphalt mixtures. These mixtures are widely used in the construction of highways, grade roads, municipal roads, airports, ports and other roads and infrastructure. According to the mixing method, asphalt mixing plants can be divided into intermittent and continuous types; according to the transportation method, they can be divided into fixed, semi-fixed and mobile types. Different classification methods are adapted to different construction environments and needs.

[0003] There are many types of asphalt mixing plants on the market. Most of them have a high-efficiency mixing effect. The bottom of this type of asphalt mixing plant is generally equipped with a discharge hopper. When the vehicle drives to the bottom of the asphalt mixing plant, the discharge valve on the discharge hopper opens to realize the unloading operation.

[0004] However, the height of the discharge hopper on this type of asphalt mixing plant is constant. When the discharge hopper is high, the distance between the discharge hopper and the vehicle is large, which can easily cause material to splash onto the outside of the vehicle during the discharge process. If the discharge hopper is low, although material splashing can be avoided, when loading vehicles of different heights, the taller vehicles will not be able to properly drive under the discharge hopper, affecting the discharge effect and causing inconvenience to users. In view of this, we have proposed an asphalt mixing plant. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 4 The utility model provides a technical solution: an asphalt mixing plant, comprising an asphalt mixing plant body 1 and a discharge hopper 2 arranged at the bottom of the asphalt mixing plant body 1, a conical bucket 20 is fixedly installed at the bottom end of the discharge hopper 2, a discharge pipe 21 is fixedly installed at the bottom end of the conical bucket 20, side plates 22 are fixedly installed on the left and right side surfaces of the discharge hopper 2, a lifting and discharging assembly 3 is provided on the discharge pipe 21, and the lifting and discharging assembly 3 includes two left and right symmetrical cylinders 30 fixedly installed on the corresponding side plates 22, a horizontal plate 34 is provided on the telescopic shafts of the two cylinders 30, a vertical cylinder 33 is fixedly installed between the two horizontal plates 34, the vertical cylinder 33 is sleeved on the discharge pipe 21 and is slidably connected between the discharge pipe 21, so as to ensure that when in use, the height of the vertical cylinder 33 can be adjusted according to the height of the vehicle, so that the unloading operation is more convenient;

[0028] Specifically, an inner anti-sticking smooth layer 4 is provided on the inner walls of the discharge hopper 2, the conical hopper 20, the discharge pipe 21 and the vertical cylinder 33. The inner anti-sticking smooth layer 4 can be made of a polymer material, such as plastic or rubber. Plastic or rubber can effectively avoid adhesion and penetration with the asphalt, forming a protective layer, so that the asphalt mixture can fall more smoothly along the discharge hopper 2, the conical hopper 20, the discharge pipe 21 and the vertical cylinder 33.

[0029] In this embodiment, a fixing plate 301 is fixedly mounted on the end of the telescopic shaft of the cylinder 30 , and the horizontal plate 34 is fixedly mounted on the bottom surface of the fixing plate 301 by a plurality of fastening bolts, so as to facilitate the fixing and mounting operation.

[0030] Specifically, a vertical guide rod 31 is fixedly installed on the bottom surface of one of the side panels 22, and the horizontal plate 34 is sleeved on the guide rod 31 and slidably connected to the guide rod 31; a guide hole 341 is provided in the horizontal plate 34, and the guide rod 31 passes through the guide hole 341 to guide the horizontal plate 34.

[0031] Furthermore, a limit plate 32 is fixedly installed at the bottom end of the guide rod 31. The limit plate 32 is located below the horizontal plate 34. The outer diameter of the limit plate 32 is larger than the aperture of the guide hole 341, so that the limit plate 32 can limit the downward movement distance of the horizontal plate 34.

[0032] In addition, a sealing ring 35 is provided on the top surface of the vertical cylinder 33. The sealing ring 35 is sleeved on the discharge pipe 21 and is slidably connected to the discharge pipe 21, so that the sealing ring 35 is used to seal the top position of the vertical cylinder 33 and the discharge pipe 21.

[0033] It is worth noting that a clamping ring 36 is fixedly installed on the top surface of the vertical cylinder 33 by multiple fastening screws. The clamping ring 36 presses the sealing ring 35 on the top surface of the vertical cylinder 33 to facilitate the loading and unloading operations of the sealing ring 35.

[0034] When the asphalt mixing plant of the present invention is in use, after a vehicle travels below the conical bucket 20, the cylinder 30 is activated and put into operation according to the height of the vehicle. When the cylinder 30 is in operation, the telescopic shaft thereon extends or contracts, which can drive the horizontal plate 34 and the vertical cylinder 33 to move, thereby adjusting the height of the vertical cylinder 33 and further adjusting the distance between the vertical cylinder 33 and the vehicle. Then, after the discharge valve in the main body 1 of the asphalt mixing plant is opened, the asphalt mixture falls downward along the discharge hopper 2, the conical bucket 20, the discharge pipe 21 and the vertical cylinder 33 into the vehicle, completing the unloading operation.
