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

[0002] Existing asphalt mixing equipment is generally installed on a vehicle, and the container of the equipment is horizontally oriented, because the asphalt inside the container needs to be fed, mixed and discharged; the stirring paddle inside it rotates clockwise or counterclockwise around the horizontal axis to drive the asphalt to be fed or discharged, and the asphalt is mixed evenly during the feeding and discharging process; however, the existing asphalt mixing equipment uses a vertical feeding method, and there is an angle difference between the vertical feeding and the opening of the container at the horizontal end, which makes it easy to leak during vertical feeding; at the same time, since the asphalt mixing equipment is generally large, its height will be higher than the height of a person, and the feeding end of the asphalt mixing equipment is located above the person, it is possible that a worker may mistakenly open the feeding door during the feeding process, causing the added material to leak directly from the feeding door, and may also fall onto the worker, causing an accident.

[0037] Such as Figures 1-5 , an asphalt mixing device, comprising: a mixing frame 1, a mixing container 2, and a feeding assembly 3;

[0038] The mixing container 2 is rotatably mounted on the mixing frame 1; a feeding frame opening 11 is provided at a horizontal end of the mixing frame 1, and the opening of the mixing container 2 passes through the feeding frame opening 11;

[0039] The feeding assembly 3 includes: a feeding fixed funnel 31, a feeding movable funnel 32, a feeding shutter 33, a horizontal telescopic plate 34, and a guiding plate 35;

[0040] The feeding fixed funnel 31 is mounted on the mixing frame 1 and is located above the feeding frame opening 11; the feeding shutter 33 is movably mounted on the feeding frame opening 11; the feeding movable funnel 32 is mounted on the feeding shutter 33; the feeding shutter 33 is provided with a shutter receiving cavity 331; the opening of the mixing container 2 extends into the shutter receiving cavity 331; the feeding fixed funnel 31, the feeding movable funnel 32, and the shutter receiving cavity 331 are sequentially communicated;

[0041] The feeding shutter 33 is provided with a material guiding opening 332 communicating with the shutter accommodating cavity 331 below the feeding movable funnel 32; one end of the horizontal telescopic plate 34 is rotatably connected to one end of the material guiding plate 35, and the material guiding plate 35 rotates to a horizontal orientation or an inclined orientation; the horizontal telescopic plate 34 is movably installed in the material guiding opening 332, driving the other end of the material guiding plate 35 to extend into or out of the opening of the mixing container 2.

[0042] This solution provides an asphalt mixing device, which is installed on the mixing frame 1 through the feeding assembly 3. By the movement of the horizontal telescopic plate 34 in the feeding shutter 33, the material guiding plate 35 is driven to extend into or out of the opening of the mixing container 2. Thus, asphalt can be introduced into the mixing container 2 through the material guiding plate 35, and the feeding shutter 33 can also be limited by the material guiding plate 35 to prevent the feeding shutter 33 from detaching from the feeding frame opening 11, solving the problem of easy material leakage when a horizontally oriented container is fed vertically.

[0043] Specifically, the mixing container 2 is rotatably installed on the mixing frame 1, and its rotation can be achieved in a known manner, such as being driven by a motor to rotate, etc.; the opening of the mixing container 2 is located at the feeding frame opening 11; a feeding shutter 33 is installed at the feeding frame opening 11, and the movement of the feeding shutter 33 can be rotation or translation; when the feeding shutter 33 moves to be located at the feeding frame opening 11, the opening of the mixing container 2 is accommodated in the shutter accommodating cavity 331 of the feeding shutter 33; above the shutter accommodating cavity 331, the feeding fixed funnel 31 and the feeding movable funnel 32 are communicated, and the materials added from the feeding fixed funnel 31 can fall to the feeding movable funnel 32, and the feeding movable funnel 32 then outputs the materials to the shutter accommodating cavity 331; at the same time, the feeding shutter 33 is also provided with a material guiding opening 332, and the horizontal telescopic plate 34 is movably installed in the material guiding opening 332; one end of the horizontal telescopic plate 34 is rotatably connected to the material guiding plate 35; when the horizontal telescopic plate 34 extends into the direction of the shutter accommodating cavity 331, the horizontal telescopic plate 34 will drive the material guiding plate 35 to extend into the opening of the mixing container 2; and one end of the horizontal telescopic plate 34 is rotatably connected to the material guiding plate 35, and the material guiding plate 35 can be in an inclined state after passing through the material guiding opening 332, such as Figure 3 ; therefore, after receiving the materials from above at one end, the material guiding plate 35 can output the materials to the inside of the mixing container 2 directionally at the other end; at the same time, when the material guiding plate 35 extends into the opening of the mixing container 2, the material guiding plate 35 is connected to the feeding shutter 33 through the horizontal telescopic plate 34, and the feeding shutter 33 cannot move, so as to limit the relative positions of the feeding shutter 33 and the mixing container 2, avoid other people accidentally opening the feeding shutter 33 during the feeding of the mixing container 2, prevent the materials from directly falling onto the personnel opening the door, and further prevent accidents during the feeding period.

[0044] Optimally, the horizontal side of the feeding shutter 33 is rotatably mounted on the feeding frame opening 11.

[0045] In this solution, the feeding shutter 33 is preferably rotatably mounted on the feeding frame opening 11. When the asphalt mixing equipment is in a non-feeding state, the feeding shutter 33 can be freely rotated, and the mixing frame 1 and the feeding shutter 33 are in a separated state. Thus, the feeding frame opening 11 of the mixing frame 1 and the shutter receiving cavity 331 of the feeding shutter 33 can be exposed, which is convenient for cleaning; or when it is necessary to output the asphalt in the mixing container 2 to the ground, the feeding shutter 33 can also be freely rotated to expose the feeding frame opening 11, and the opening of the mixing container 2 directly outputs the asphalt to the road surface; and when feeding is required and asphalt mixing is to be carried out, the horizontal telescopic plate 34 is used to drive the guiding plate 35 to extend into the opening of the mixing container 2, and the guiding plate 35 restricts the rotation of the feeding shutter 33, so as to ensure that it will not be opened during feeding.

[0046] After feeding is completed, the guiding plate 35 can be driven to rotate from an inclined orientation to a horizontal orientation. For example, the guiding plate 35 can be lifted upward beside the mixing frame 1 with a tool to make the guiding plate 35 horizontally oriented. In the optimal embodiment, the feeding assembly 3 further includes: an adjusting rod 4;

[0047] One end of the adjusting rod 4 is rotatably connected to the guiding plate 35, and the other end of the adjusting rod 4 extends outside the guiding through-opening 332; the adjusting rod 4 moves through the guiding through-opening 332, driving the guiding plate 35 to rotate to a horizontal orientation or an inclined orientation.

[0048] In this solution, the rotation of the guiding plate 35 can be adjusted by the adjusting rod 4, and the angle of the guiding plate 35 can be controlled. During the period when the guiding plate 35 extends into the opening of the mixing container 2, the angle between the guiding plate 35 and the horizontal telescopic plate 34 can be kept at 180°, so that the guiding plate 35 horizontally extends into the opening of the mixing container 2; after the guiding plate 35 extends into the opening of the mixing container 2, the adjusting rod 4 can be driven to move in a direction away from the opening of the mixing container 2, thereby driving the guiding plate 35 to rotate downward, so that the guiding plate 35 rotates to an inclined extension, and the materials on the guiding plate 35 can be guided into the opening of the mixing container 2 along the inclined direction of the guiding plate 35 under the action of gravity, thereby improving the feeding efficiency. After the mixing container 2 finishes feeding and mixing, the adjusting rod 4 can be driven to move in the direction of the opening of the mixing container 2, driving the guiding plate 35 to rotate to a horizontal state, and then driving the horizontal telescopic plate 34 to gradually extend out of the guiding through-opening 332, and finally separating the guiding plate 35 from the mixing frame 1. At this time, the feeding shutter 33 can be freely opened.

[0049] Optimally, the feeding assembly 3 further includes: a rotating arm 5;

[0050] One end of the rotating arm 5 is rotatably connected to the adjusting rod 4, and the other end of the rotating arm 5 is rotatably connected to the material guiding plate 35.

[0051] In this solution, the adjusting rod 4 can be directly or indirectly connected to the material guiding plate 35. For the indirect connection method, this solution preferably uses the rotating arm 5 to rotatably connect the adjusting rod 4 and the material guiding plate 35. The rotating arm 5 can have a single or multiple degrees of freedom, so as to facilitate the adaptive adjustment of the angle of the material guiding plate 35, and the rotation of the material guiding plate 35 can be converted into the horizontal movement of the adjusting rod 4.

[0052] Optimally, a rod guiding groove 341 is provided at the bottom of the horizontal telescopic plate 34; the adjusting rod 4 is movably installed in the rod guiding groove 341.

[0053] In this solution, the adjusting rod 4 can be arranged at any position of the horizontal telescopic plate 34 or the material guiding opening 332 according to needs. In the optimal embodiment, the adjusting rod 4 is installed in the rod guiding groove 341 at the bottom of the horizontal telescopic plate 34, which can avoid occupying too much space of the material guiding opening 332, make the material guiding opening 332 more compact, and thus facilitate the guiding effect on the horizontal telescopic plate 34. At the same time, the inner wall of the rod guiding groove 341 can guide the horizontal movement of the adjusting rod 4, thereby improving the rotation stability of the material guiding plate 35.

[0054] Optimally, the feeding assembly 3 further includes: a buffer spring 36;

[0055] The buffer spring 36 is sleeved on the adjusting rod 4. The adjusting rod 4 is provided with a movable pressing surface 343, and the rod guiding groove 341 is provided with a fixed pressing surface 342; one end of the buffer spring 36 contacts the fixed pressing surface 342, and the adjusting rod 4 moves and drives the movable pressing surface 343 to abut against the other end of the buffer spring 36.

[0056] In this solution, the buffer spring 36 can be used to limit the adjusting rod 4 and provide a buffering effect for the movement of the adjusting rod 4, thereby slowing down the movement of the material guiding plate 35; specifically, the adjusting rod 4 moves in the rod guiding groove 341. For example, the adjusting rod 4 moves towards or away from the opening direction of the mixing container 2. The fixed pressing surface 342 is arranged at the end point of the moving direction. Therefore, the movement of the adjusting rod 4 will drive its movable pressing surface 343 to abut against the buffer spring 36, and both the movable pressing surface 343 and the fixed pressing surface 342 compress the buffer spring 36 together. The buffer spring 36 can slow down the moving speed of the adjusting rod 4 at the end point of the movement, thereby slowly adjusting the angle of the material guiding plate 35.

[0057] Optimally, it further includes: a driving assembly 6;

[0058] The driving assembly 6 includes: a driven driving gear 61, a driving driving gear 62 and a driving motor 63;

[0059] The driven drive gear 61 is sleeved outside the mixing container 2; the driving drive gear 62 meshes with the driven drive gear 61; the output end of the drive motor 63 is connected to the driving drive gear 62 for driving the driving drive gear 62 to rotate, driving the driven drive gear 61 to rotate, and enabling the mixing container 2 to rotate relative to the mixing frame 1.

[0060] In this solution, the driven drive gear 61 is arranged outside the mixing container 2. When it is necessary to mix the mixing container 2, the drive motor 63 can be started. The output end of the drive motor 63 drives the driving drive gear 62 to rotate, driving the driven drive gear 61 to rotate synchronously, thereby driving the mixing container 2 to rotate, and enabling the asphalt to be stirred and mixed in the mixing container 2. In some embodiments, a spiral stirring paddle (not shown) is provided in the mixing container 2.

[0061] Optimally, it further includes: a discharge plate 7;

[0062] The discharge plate 7 is installed on the mixing frame 1; the discharge plate 7 is inclined, and the upper end of the discharge plate 7 is located directly below the feed frame opening 11.

[0063] The feeding shutter 33 is arranged at the feed frame opening 11. When the feeding shutter 33 is opened, the feed frame opening 11 can be exposed, thereby directly exposing the opening of the mixing container 2. The mixing container 2 can directly discharge the asphalt, and the discharge plate 7 can receive the asphalt falling from the upper mixing container 2. The asphalt falls along the wall surface in the inclined direction of the discharge plate 7, which can provide a guiding effect for the discharge of the asphalt, thereby preventing the asphalt from falling directly below the mixing frame 1.

[0064] An asphalt mixing truck is provided with the above-mentioned asphalt mixing equipment.

[0065] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
