[0027] Specific embodiments of the asphalt pavement integrated maintenance vehicle loading machine provided by this utility model:

[0028] Please see Figure 1-6 The asphalt pavement comprehensive maintenance vehicle loading machine includes a track frame 1, a fixed seat 2, a lifting frame 3, a rotating frame 4, a hopper 9, and a hydraulic cylinder 10.

[0029] The track frame 1 includes two vertical track grooves 11 with opposite openings. The upper end of the track groove 11 is equipped with a stop plate to close it. The upper end of the track groove 11 is bent towards the front of the maintenance vehicle to form a curved arc track, so that the upper end of the track groove 11 is inclined to the feed port of the frying pot on the front side. A cross brace 12 is connected between the lower front sides of the two track grooves 11.

[0030] The upper and lower ends of the track frame 1 are respectively connected to the upper end of the frying pot and the rear of the maintenance vehicle chassis. The lower end of the track groove 11 is connected to the maintenance vehicle chassis by bolts. The upper end of the track groove 11 is welded with a support, which is connected to the upper end of the frying pot by bolts.

[0031] On the integrated maintenance vehicle, the frying pot for heating raw materials is installed at the rear of the vehicle and placed in the center; the upper end of the frying pot is equipped with a feeding port, which is designed to be inclined backward.

[0032] The fixed seat 2 is installed on the upper end of the frying pot. The fixed seat 2 is welded to the frying pot. Two fixed seats 2 are provided, corresponding to the two sides of the first end of the rotating frame 4 respectively. The first end of the rotating frame 4 is hinged to the two fixed seats 2 respectively through two pins.

[0033] The rotating frame 4 includes two connecting arms 41 and a crossbar connecting the two connecting arms 41. Each connecting arm 41 has a cylinder seat 43 on its side that is hinged to the hydraulic cylinder 10. The cylinder seat 43 is connected to the connecting arm 41 by welding. The two connecting arms 41 are respectively hinged to two fixed seats 2 via pins. There are two cylinder seats 43.

[0034] Two hydraulic cylinders 10 are hinged between the upper end of the track frame 1 and the rotating frame 4. Specifically, the two ends of the hydraulic cylinder 10 are respectively hinged to the cylinder seat 43 and the support at the upper end of the track groove 11 via pins. The extension and retraction of the hydraulic cylinder 10 causes the rotating frame 4 to rotate around the fixed seat 2.

[0035] The lifting frame 3 moves up and down along the track frame 1. The hopper 9 is installed on the rear side of the lifting frame 3. Specifically, the lifting frame 3 includes a frame body 31. Several traveling wheels 34 that move along the track groove 11 are installed on both sides of the frame body 31. The traveling wheels 34 are arranged in two layers, with a total of four, supporting the frame body 31 to move up and down along the track frame 1. Two swing arms 32 are hinged to the upper rear side of the frame body 31. A connecting plate 33 for installing the hopper 9 is connected between the middle of the two swing arms 32. The hopper 9 is connected to the connecting plate 33 by bolts. The swing arms 32 are L-shaped, and the ends of the two swing arms 32 are located on both sides of the hopper 9. The hopper 9 can move up and down with the lifting frame 3, and can also be tilted to feed material under the support of the swing arms 32 and the connecting plate 33. The upper end of the hopper 9 is designed with an slanted opening, which can facilitate loading and reduce material spillage.

[0036] The second end of the rotating frame 4 is hinged to the lifting frame 3 with two connecting rods 5. The upper ends of the two connecting rods 5 are respectively connected to the two connecting arms 41 by pins, and the lower ends of the two connecting rods 5 are respectively hinged to the ends of the two swing arms 32 by pins.

[0037] In some embodiments, the connecting rod 5 is divided into two sections, with forward and reverse threaded sections 51 at their adjacent ends; that is, one connecting rod 5 has a forward threaded section 51 and the other connecting rod 5 has a reverse threaded section 51. The two connecting rod sections 5 are connected by a threaded adjusting sleeve 52 for adjusting length. The adjusting sleeve 52 has symmetrical flat surfaces on both outer sides to facilitate length adjustment by rotating a wrench. A fastening nut is fitted on the outer side of the threaded section 51 to limit the length of the connecting rod 5 and prevent loosening. The hopper 9 is kept level in the initial state by adjusting the length of the connecting rods 5 on both sides.

[0038] The rotating frame 4 is hinged to a connecting piece 6. A door seat 8 is welded to the front side of the feeding port of the frying pot. The door seat 8 is fixed to the frying pot. The door seat 8 is hinged to a rotating material gate 7 that can cover the feeding port. The material gate 7 is hinged to the connecting piece 6. As the rotating frame 4 raises and lowers the hopper 9, the material gate 7 is automatically opened and closed through the connecting piece 6.

[0039] On the rotating frame 4, a locking member 42 for pressing the material gate 7 is connected between the two connecting arms 41. When the material gate 7 is closed, the locking member 42 presses against the upper side of the connecting member 6 and the material gate 7 to prevent the hinged material gate 7 from loosening, ensuring good smoke prevention and sealing, and reducing pollution.

[0040] Initially, the material gate 7 is closed, the hopper 9 is at the bottom, and the piston rod of the hydraulic cylinder 10 is retracted. When raw materials need to be fed using the feeder, the feeder button is rotated in the up direction. Driven by the hydraulic system, the piston rod of the hydraulic cylinder 10 extends, causing the rotating frame 4 to rotate around the pin on the fixed base 2. The connecting rod 5, connected to the connecting arm 41 at the second end of the rotating frame 4, pulls the lifting frame 3 up within the track groove 11. The hopper 9 mounted on the lifting frame 3 rises, and the material gate 7 gradually opens as the rotating frame 4 rotates. When the traveling wheels 34 on the lifting frame 3 are raised to the arc-shaped track of the track frame 1, the rotating frame 4 continues to rotate around the pin. Link 5 pulls the swing arm 32 on the lifting frame 3 to begin changing angle until the traveling wheel 34 touches the stop plate at the upper end of the track groove 11. Then, link 5 pulls the swing arm 32 to begin rotating around the frame 31. The hopper 9, which is installed on the connecting plate 33 between the two swing arms 32, also begins to rotate. The material gate 7 slowly opens completely until the hydraulic cylinder 10 extends its stroke, the rotating frame 4 is in position, the material gate 7 is fully opened, and the angle of the hopper 9 is rotated to align with the feeding port of the roasting pot. The raw material automatically falls into the roasting pot, and the feeding is completed. Conversely, when hopper 9 needs to descend, rotating the feeder button in the descent direction retracts the piston rod of hydraulic cylinder 10. The connecting arm 41 of rotating frame 4 rotates downwards, causing connecting rod 5 to push the swing arm 32 of lifting frame 3 downwards. The traveling wheels 34 slowly move from the arc track into the vertical track. When hopper 9 reaches the vertical track, it remains vertical and continues to descend. The material gate 7 gradually closes. When hopper 9 reaches its lowest initial position, the material gate 7 is completely closed, completing the entire descent action. The lifting and lowering of the feeder and the opening and closing of the material gate 7 are mechanically linked, resulting in a simple structural design and stable and reliable operation.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features.
