Drawings

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic view of the structure of the barrel wall of the present invention;

wherein, the device comprises a spray gun 1, a gasoline engine 2, a fence 3, a heat preservation barrel 4, a heating rod 5, a spring 6, a wall plate 7, a barrel wall 8, a generator 9, a generator belt 10, a gear pump 11, a frame 12, a pull rod 13, a gear pump belt 14, a heat preservation layer 15 and a heating wire 16.

Detailed Description

As shown in fig. 1, the conventional hand-push type asphalt spreader includes a gear pump 11 having an oil outlet pipe and an oil suction pipe, a gasoline engine 2 drivingly connected to the gear pump 11, and a frame 12 connected to the gear pump 11 and the gasoline engine 2. The tail end of the oil outlet pipe is also connected with a spray gun 1, and the front end of the frame 12 is also provided with a pull rod 13. The utility model discloses a create the point and lie in: the gasoline engine is characterized by further comprising a generator 9 in transmission connection with the gasoline engine 2 and a heat-insulating barrel 4 communicated with the oil suction pipe, wherein the generator 9 and the heat-insulating barrel 4 are connected with the frame 12, and a heating rod 5 electrically connected with the generator 9 is arranged in the heat-insulating barrel 4. Set up like this alright make hand propelled pitch spreader when carrying out the construction operation of little volume of spraying, the pitch in the bucket can keep enough temperature, and its mobility can not receive the influence, can remain the homogeneity of spraying throughout, finally guarantees construction quality, and reduces equipment and energy loss because of pitch stickness increases and bring.

Further: the generator 9 is connected with the gasoline engine 2 through a generator belt 10; the gear pump 11 is connected with the gasoline engine 2 through a gear pump belt 14. The generator 9 and the gear pump 11 are respectively connected with the gasoline engine 2 through a belt, so that the generator belt 10 can be conveniently taken down when the weather is hot enough and the heat is preserved only by the heat preservation barrel 4 without heating, thereby reducing the output power of the gasoline engine 2 and the oil consumption.

Further: the periphery of the heat-insulating barrel 4 is provided with a fence 3. When high temperature pitch is deposited in heat-preserving container 4, have constructor mistake and touch 4 high temperature regions of heat-preserving container and the risk of scald, therefore increase rail 3 and can effectively prevent that the workman mistake from touching and the scald that arouses.

Further: the fence 3 is higher than the top surface of the heat-insulating barrel 4. Because be convenient for carry out maintenance work such as clearance to heat-preserving container 4, the top surface of rail 3 does not set up protective fence usually, nevertheless if rail 3 and heat-preserving container 4 are equal in height, then still have certain workman mistake and touch the risk that heat-preserving container 4 top surface high temperature region scalded, set up rail 3 and can further reduce this risk higher than heat-preserving container 4's top surface.

Further: the heat-insulating barrel 4 is connected with the frame 12 through a spring 6. Spring 6 has two effects, firstly can play the cushioning effect when the push-and-pull dolly, effectively reduce heat-preserving container 4 and receive vibrations and follow the risk of bung hole spill, secondly play and set up the effect of thermal resistance between heat-preserving container 4 and frame 12, because heat-preserving container 4 does not laminate with frame 12, both only have the tiny cross-section of spring 6 and connect, then heat conduction between the two can reduce by a wide margin, prevent that the great frame 12 of size from playing the radiating effect to heat-preserving container 4, heat preservation effect of heat-preserving container 4 has been guaranteed.

Further: the heat-preserving container 4 is provided with a container wall 8, the number of the springs 6 is more than 4, and the springs 6 are arranged at the edge of the container wall 8 on the bottom surface of the heat-preserving container 4 at equal intervals. The spring 6 that sets up like this can carry out stable support to heat-preserving container 4, prevents that heat-preserving container 4 from heeling crooked.

Further, as shown in fig. 2: the barrel wall 8 comprises a wall plate 7 and an insulating layer 15 coated on the outer side surface of the wall plate 7. The arrangement of the heat-insulating layer 15 is an optimal implementation mode for realizing the heat-insulating function of the heat-insulating barrel 4, and an inner container structure and an outer container structure can be used, so that the cost is high. Set up heat preservation 15 and not only played the heat retaining effect in the bucket, still had the effect that reduces staving surface temperature relative to the external world, prevented that the unexpected touching staving of personnel and the condition of scalding from appearing.

Further: a heating wire 16 is arranged on the inner side surface of the wall plate 7, and the heating wire 16 is electrically connected with the generator 9. The heating effect on the asphalt can be further enhanced by additionally arranging the heating wires 16 in the wall plate 7, particularly, the asphalt is mainly cooled rapidly and has lower temperature near the wall plate 7, the integral fluidity of the asphalt is ensured by directly heating the asphalt, the improvement of the spraying operation quality is facilitated, the energy configuration can be optimized, and the energy is utilized in the most needed part.
