Technical Field
[0001] The utility model relates to the technical field of asphalt unloading, in particular to a discharging mechanism of a conveying device for asphalt. Background Art
[0002] Asphalt is a black and brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, in a liquid state, with a black surface, soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic cementing material. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking, petroleum asphalt is the residue after crude oil distillation, and natural asphalt is stored underground, some forming ore layers or accumulating on the earth's crust surface. Asphalt is mainly used in industries such as coatings, plastics, rubber, etc. and for paving roads, etc.
[0003] In civil engineering, asphalt is a widely used waterproof and anti-corrosion material, mainly used for waterproofing of roofs, floors and underground structures, anti-corrosion of wood and steel. Asphalt is also a widely used pavement structure cementing material in road engineering. It can be used to build asphalt pavements with different structures by being proportionally combined with mineral materials with different compositions. It is widely used in expressways. When asphalt is processed, a conveying device is needed for conveying, and a discharging device is needed for discharging the conveying device. The problems existing in the prior art are: it is not convenient to aggregate asphalt for discharging, which easily causes asphalt to scatter everywhere, and it is not convenient for users to collect asphalt. Summary of the Utility Model
[0004] To overcome the deficiencies of the prior art, the utility model provides a discharging mechanism of a conveying device for asphalt, which includes a vehicle frame. Wheels for supporting the movement of the vehicle frame are rotatably connected to four end corners of the vehicle frame. A hopper is hingedly connected to the upper surface of the vehicle frame through a first hinge. A first discharge chute is formed on one side of the hopper close to the first hinge. An outer sealing door for closing the first discharge chute is hingedly connected to the hopper, and a guiding component for aggregating materials is arranged on the outer sealing door.
[0005] To achieve the above object, asphalt is placed in the hopper, and the hopper is pushed to transport asphalt. The vehicle frame and the hopper are supported by the wheels and the vehicle frame is driven to move. When discharging asphalt, the hopper is pushed, and the hopper rotates around the first hinge. The outer sealing door rotates under the action of gravity and disconnects from the hopper, exposing the first discharge chute. At this time, the asphalt in the hopper moves out of the hopper through the first discharge chute to complete the discharging operation. By setting the guiding component, the function of aggregating and guiding the overflowing asphalt is realized, the discharging efficiency of asphalt is improved, and it is convenient to collect asphalt.
[0006] Further, the material guiding assembly includes ear plates that fit against the outer sealing door and a material guiding plate disposed inside the hopper and abutting against the bottom and side walls of the hopper groove. The two material guiding plates are arranged oppositely and obliquely. The material guiding plate and the ear plate are integrally formed through a connecting plate located at the upper end of the outer sealing door. Through holes are formed among the material guiding plate, the ear plate, and the connecting plate. The material guiding plate, the ear plate, and the connecting plate are sleeved outside the outer sealing door through the through holes and are tightly clamped and connected to the outer sealing door.
[0007] Through the above technical solution, the material guiding plate, the ear plate, and the connecting plate are tightly clamped and connected to the outer sealing door, so as to rotate along with the rotation of the outer sealing door, improving the discharging efficiency. The material guiding plate is obliquely arranged to assist in discharging and realize the function of gathering materials.
[0008] Further, an extension plate is fixed to the bottom of the outer sealing door, and a limiting assembly for cooperating with the extension plate to achieve a self-locking function is provided on the vehicle frame.
[0009] Through the above technical solution, the possibility that the outer sealing door cannot close the first discharge chute due to shaking during the horizontal movement of the hopper and the asphalt overflows through the first discharge chute is reduced.
[0010] Further, the limiting assembly includes a mounting plate disposed below the hopper. The mounting plate is obliquely arranged. One end of the mounting plate is fixedly connected to the lower surface of the hopper, and the other end is hinged with a hook plate. The hook plate is hinged to the vehicle frame. The hook plate extends out of the vehicle frame, and the part of the hook plate extending out of the vehicle frame bends upward toward the extension plate side. The upwardly bent side of the hook plate is clamped outside the extension plate and is tightly clamped and connected to the extension plate.
[0011] Through the above technical solution, when the hopper is in a horizontal state, the hook plate is located outside the extension plate and is tightly clamped and connected to the extension plate to achieve the self-locking function. After the hopper rotates and is disconnected from the vehicle frame, the mounting plate drives the hook plate to rotate, and the hook plate is disconnected from the extension plate, without affecting the rotation of the outer sealing plate.
[0012] Further, an auxiliary discharging assembly is provided on the outer sealing door.
[0013] Through the above technical solution, when the asphalt is relatively viscous and it is difficult for the asphalt to be completely discharged when the hopper rotates, by providing the auxiliary discharging assembly, it is convenient to discharge the asphalt.
[0014] Further, the auxiliary discharging assembly includes a second discharge chute opened on the outer sealing door. An inner sealing door for closing the second discharge chute is hinged to the outer sealing door through a second hinge. The inner sealing door and the outer sealing door are detachably fixed through a bolt.
[0015] Through the above technical solution, the outer sealing door and the inner sealing door are detachably fixedly connected by a bolt. When the asphalt is relatively viscous and it is difficult for the asphalt to be completely discharged when the hopper rotates, the bolt is opened to disconnect the connection between the inner sealing door and the outer sealing door. When the inner sealing door rotates around the second hinge, the staff grabs a shovel or other tools and pushes the viscous asphalt to move out of the hopper through the second discharge chute. The asphalt moves along the inner sealing door and drops, realizing the discharging.
[0016] In summary, the discharging mechanism of the asphalt conveying device has the following beneficial effects:
[0017] (1) For the discharging mechanism of the asphalt conveying device, the asphalt is placed in the hopper, and the hopper is pushed to transport the asphalt. The wheel supports the frame and the hopper and drives the frame to move. When discharging the asphalt, the hopper is pushed, and the hopper rotates around the first hinge. The outer sealing door rotates under the action of gravity and disconnects from the hopper, exposing the first discharge chute. At this time, the asphalt in the hopper moves out of the hopper through the first discharge chute, realizing the discharging operation. By setting the material guiding component, the function of gathering and guiding the overflowing asphalt is realized, improving the asphalt discharging efficiency and facilitating the collection of asphalt.
[0018] (2) For the discharging mechanism of the asphalt conveying device, the outer sealing door and the inner sealing door are detachably fixedly connected by a bolt. When the asphalt is relatively viscous and it is difficult for the asphalt to be completely discharged when the hopper rotates, the bolt is opened to disconnect the connection between the inner sealing door and the outer sealing door. When the inner sealing door rotates around the second hinge, the staff grabs a shovel or other tools and pushes the viscous asphalt to move out of the hopper through the second discharge chute. The asphalt moves along the inner sealing door and drops, realizing the discharging. Description of the Drawings

Specific embodiments
[0028] Next, the technical solutions of the present utility model will be described more clearly and completely by combining the accompanying drawings and describing the preferred embodiments of the present utility model.
[0029] As Figures 1-7 shown, a discharging mechanism of a conveying device for asphalt in a preferred embodiment of the present utility model includes a vehicle frame 1. Wheels 2 for supporting the movement of the vehicle frame 1 are rotatably connected to the four end corners of the vehicle frame 1. A hopper 4 for accommodating and transporting asphalt and adapted to the vehicle frame 1 is hingedly connected to one side of the upper surface of the vehicle frame 1 through a first hinge 3. A hinge is fixed to the side of the hopper 4 away from the first hinge 3, and a bolt 19 is fixed to the end of the hinge away from the hopper 4. A sleeve adapted to the bolt 19 is fixed to the vehicle frame 1, and the bolt 19 is inserted into the sleeve and tightly connected to the sleeve.
[0030] As Figure 1 and Figure 2 and Figure 3 , a first discharge chute 5 is provided on the side of the hopper 4 close to the first hinge 3. An outer sealing door 6 for closing the first discharge chute 5 is provided on the hopper 4. The outer sealing door 6 abuts against the outer side wall of the hopper 4. Two oppositely arranged connecting rods 7 with an L-shaped cross-section are fixed to the top of the outer sealing door 6. Two oppositely arranged ear seats 8 are fixed to the upper surface of the hopper 4. The connecting rods 7 extend into the ear seats 8 and are hingedly connected to the ear seats 8. Two oppositely arranged handles 9 are fixed to the outer side wall of the hopper 4.
[0031] As Figure 1 and Figure 2 and Figure 3, In the initial state, the asphalt is placed in the hopper 4. The pin 19 is inserted into the sleeve and tightly connected to the sleeve. The hopper 4 is limited by the hinge, the pin 19 and the sleeve, reducing the possibility of the hopper 4 flipping during movement. The staff grabs the handle 9 and manually pushes the handle 9, driving the hopper 4, the frame 1 and the wheels 2 to move horizontally until the device moves to a suitable position. At this time, the staff grabs the pin 19 and pulls out the pin 19 forcefully. The pin 19 disconnects from the sleeve. Then the staff pushes the handle 9 upward. The rotation of the handle 9 drives the hopper 4 fixed to the handle 9 to rotate around the first hinge 3. The outer sealing door 6 is hinged to the hopper 4 through the connecting rod 7 and the ear seat 8. When the hopper 4 rotates, the outer sealing door 6 disconnects from the hopper 4 under the action of gravity, exposing the first discharge chute 5. At this time, the asphalt in the hopper 4 moves out of the hopper 4 through the first discharge chute 5, realizing the unloading operation.
[0032] As Figure 1 and Figure 2 and Figure 3 and Figure 6 and Figure 7 , in order to reduce the possibility that the outer sealing door 6 cannot close the first discharge chute 5 due to shaking during the horizontal movement of the hopper 4, causing the asphalt to overflow through the first discharge chute 5, an extension plate 10 is fixed to the bottom of the outer sealing door 6, and a limit component is provided on the frame 1 to cooperate with the extension plate 10 to achieve a self-locking function.
[0033] As Figure 1 and Figure 2 and Figure 3 and Figure 6 and Figure 7 , the limit component includes a mounting plate 11 arranged below the hopper 4. The mounting plate 11 is inclined. One end of the mounting plate 11 is fixedly connected to the lower surface of the hopper 4, and the other end is hinged with a hook plate 12. The hook plate 12 is hinged to the frame 1. The part of the hook plate 12 extending out of the frame 1 bends upward and extends toward the extension plate 10 side. The upward-bending and extending side of the hook plate 12 is stuck outside the extension plate 10 and tightly connected to the extension plate 10.
[0034] As Figure 1 and Figure 2 and Figure 3 and Figure 6 and Figure 7, when the hopper 4 is in a horizontal state, the extension plate 10 is arranged vertically, and the upwardly curved extension part of the hook plate 12 is located outside the extension plate 10 and is tightly connected to the extension plate 10 to achieve the self-locking function. At this time, the outer sealing door 6 is closely attached to the hopper 4 to close the first discharge chute 5, and asphalt cannot overflow from the first discharge chute 5. When the hopper 4 is tilted, the hopper 4 will drive the mounting plate 11 fixed to the hopper 4 to rotate. The rotation of the mounting plate 11 will drive the hook plate 12 hinged to the mounting plate 11 to rotate. The hook plate 12 rotates and disconnects from the extension plate 10. Then, the outer sealing door 6 rotates under the action of gravity and cannot close the first discharge chute 5. At this time, the asphalt overflows through the first discharge chute 5 to achieve discharging.
[0035] As Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 , in order to reduce the possibility that asphalt scatters everywhere during the discharging process and increases the difficulty of collection, a material guiding component for aggregating materials is provided on the outer sealing door 6.
[0036] As Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 , the material guiding component includes an ear plate 14 arranged axially and attached to the outer sealing door 6, and a material guiding plate 13 arranged in the hopper 4 and abutted against the bottom and wall of the hopper 4 groove. The material guiding plate 13 is completely attached to the bottom and wall of the hopper 4 groove to reduce the possibility that asphalt enters the gap between the material guiding plate 13 and the hopper 4 and affects the discharging. The material guiding plate 13 is inclined, and two material guiding plates 13 are arranged oppositely to achieve the material guiding function. The material guiding plate 13 and the ear plate 14 are integrally formed through a connecting plate 15 located at the upper end of the outer sealing door 6. Through holes 16 are provided between the material guiding plate 13, the ear plate 14 and the connecting plate 15. The through holes 16 are adapted to the size of the outer sealing door 6. The material guiding plate 13, the ear plate 14 and the connecting plate 15 are sleeved outside the outer sealing door 6 through the through holes 16 and are completely attached to the outer sealing door 6. A rubber sealing strip is fixed on the side of the material guiding plate 13, the ear plate 14 and the connecting plate 15 facing the outer sealing door 6. The ear plate 14 and the outer sealing door 6 are fixed by screws to facilitate the fixed connection between the material guiding plate 13, the ear plate 14, the connecting plate 15 and the outer sealing door 6. A rubber sealing strip for filling the gap between the material guiding plate 13 and the inner cavity wall and bottom of the hopper 3 is fixed on the side of the material guiding plate 13 facing the hopper 4, further improving the sealing performance of the connection between the material guiding plate 13 and the hopper 4 and reducing the possibility that asphalt enters the gap between the material guiding plate 13 and the hopper 4. The side of the material guiding plate 13 away from the ear plate 14 is rounded and is adapted to the size of the hopper 4. The material guiding plate 13 will not be stuck by the hopper 4 when rotating with the outer sealing door 6.
[0037] As Figure 1 and Figure 2 and Figure 3and Figure 4 and Figure 5 , when it is necessary to guide the asphalt, the staff sets the guide plate 13, the ear plate 14 and the connecting plate 15 outside the outer sealing door 6 through the through hole 16 when the hopper 4 does not contain asphalt. The side of the guide plate 13 facing the groove wall and the bottom of the hopper 4 is completely attached to the groove wall and the bottom of the hopper 4. The guide plate 13, the ear plate 14 and the connecting plate 15 are completely attached to the outer side wall of the outer sealing door 6. The ear plate 14 and the outer sealing door 6 are fixed by screws. When the hopper 4 rotates, the outer sealing door 6 rotates under the action of gravity, driving the guide plate 13, the ear plate 14 and the connecting plate 15 fixed to the outer sealing door 6 to rotate. The guide plate 13 rotates to realize the function of guiding the overflowing asphalt. The staff adjusts the rotation angle of the hopper 4 according to the degree of asphalt guiding required. When the rotation angle of the hopper 4 is small, the guide plate 13 still contacts the hopper 4, and at this time, the guiding function is maximized.
[0038] Such as Figure 1 and Figure 2 and Figure 3 and Figure 4 , when the asphalt is relatively viscous and it is difficult for the asphalt to be completely discharged when the hopper 4 rotates, an auxiliary discharging component is provided on the outer sealing door 6 to provide a second discharging method to facilitate the discharging of the asphalt.
[0039] Such as Figure 1 and Figure 2 and Figure 3 and Figure 4 , the auxiliary discharging component includes a second discharging groove 17 opened on the outer sealing door 6. The size of the second discharging groove 17 is the same as the inner diameter size of the hopper 4. An inner sealing door 18 for closing the second discharging groove 17 is hinged to the outer sealing door 6 through a second hinge 20. The inner sealing door 18 and the outer sealing door 6 are detachably and fixedly connected by a bolt 19. When the inner sealing door 18 and the outer sealing door 6 are fixedly connected, their surfaces are flush.
[0040] Such as Figure 1 and Figure 2 and Figure 3 and Figure 4 , the bolt 19 is an existing device, so it will not be elaborated here. In the initial state, the inner sealing door 18 and the outer sealing door 6 are detachably and fixedly connected by the bolt 19 to close the second discharging groove 17, which does not affect the discharging of the asphalt. When the second discharging method is required, the slot is opened, and the inner sealing door 18 is manually rotated. The inner sealing door 18 rotates around the second hinge 20 until the end of the inner sealing door 18 abuts against the ground. At this time, the staff grabs a shovel or other tools and pushes the viscous asphalt to move out of the hopper 4 through the second discharging groove 17. The asphalt moves and drops along the inner sealing door 18 to realize discharging. A rubber sealing ring for filling the gap between the inner sealing door 18 and the outer sealing door 6 is fixed on the outer periphery of the inner sealing door 18.
[0041] The above specific embodiments only describe the preferred embodiments of the present utility model, rather than limiting the protection scope of the present utility model. Without departing from the design concept and spirit scope of the present utility model, various deformations, substitutions and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model according to the written description and drawings provided by the present utility model shall all fall within the protection scope of the present utility model.
