Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A road asphalt paving device includes a support bucket 1, a discharge pipe 2, and a feed pipe 3. The discharge pipe 2 is located at the bottom of the support bucket 1 and communicates with it. The feed pipe 3 is located at the top of the support bucket 1 and communicates with it. Insulation components 4 are fixedly connected to both sides of the support bucket 1. An exhaust component 5 is connected to the top of the right side of the support bucket 1. The exhaust component 5 includes a connecting box 51 that communicates with the support bucket 1. A filter cylinder 52 is connected to the top of the connecting box 51. A limit ring 53 is fixedly connected to the inner wall of the filter cylinder 52. A filter element 54 is movably connected to the top of the limit ring 53. The filter element 54 is equipped with a porous medium, such as carbon black, silica gel, activated carbon, molecular sieve, and porous ceramics, to react with asphalt fumes. The filter element 54 is fixedly connected to the top of the filter cartridge 54 by a lifting ring 55. Both sides of the filter cartridge 52 are fixedly connected to brackets 56. The inner surface of the brackets 56 is movably connected to positioning blocks 57. One side of the positioning blocks 57 is fixedly connected to a top cover plate 58. With the exhaust assembly 5 set up, the device uses the top cover plate 58 to be set on the top of the filter cartridge 52, which effectively prevents high-temperature gas from directly rushing out and causing damage to the workers' bodies. The filter element 54 filters and absorbs the gas in the asphalt, avoiding the harm to the body caused by the gas after the asphalt is heated. The filter element 54 can be replaced simply by pulling up the lifting ring 55, which is convenient for collection.

[0022] Example 2 differs from Example 1 in that: a road asphalt paving device includes an insulation component 4 comprising a support plate 41 fixedly connected to the surface of a carrying bucket 1, with reinforcing ribs on the surface of the support plate 41. A bottom cover 42 is movably connected to the bottom of the carrying bucket 1, with a recessed handle on the surface of the bottom cover 42. An electric heating element 43 is fixedly connected to the inner wall of the bottom cover 42. The electric heating element 43 is made of PTC and is directly heated when energized. A screw rod 44 passes through the surface of the support plate 41, with an anti-slip handle at one end. A threaded groove 45 is formed on the surface of the bottom cover 42, with the inner wall of the threaded groove 45 fitting with the screw rod 44. Through the insulation component 4, the device, with the bottom cover 42 and the electric heating element 43, allows the electric heating element 43 to be quickly and completely removed.

[0023] A stirring motor is installed on the top of the bearing tank 1, and stirring blades are installed on the surface of the output shaft of the stirring motor. The electric heating element 43 and the stirring motor are electrically connected to an external power supply through corresponding control switches. The electric heating element 43 and the stirring motor are both existing technologies, and their specific structures, working principles and electrical connections are not described in detail here.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Before operation, material is added through the feed pipe 3. During operation, the stirring motor and the electric heating element 43 on the inner wall of the bottom cover 42 are turned on to continuously and stably heat the inside of the bearing tank 1. After a period of operation, when periodic maintenance is required, rotate the screw rod 44 to separate the screw rod 44 from the threaded groove 45, then pull down the bottom cover 42 and the electric heating element 43, and directly remove the bottom cover 42 and the electric heating element 43 from the bottom of the bearing tank 1. The electric heating element 43 can then be disassembled for maintenance. (The last sentence appears to be incomplete and possibly refers to a different process.) The heating of asphalt emits an odor, and the high-temperature gas overflows out of the filter element 54 at high speed. Then, it overflows outward in a ring shape along the bottom of the inner wall of the top cover plate 58, which can prevent the high-temperature airflow from directly hitting the filter element 54 and filtering it directly. When the filter element 54 is running at full load, pull up the top cover plate 58 to separate the positioning block 57 from the bracket 56, lift up the lifting ring 55, and directly pull out the filter cylinder 52 in the filter element 54. Then replace it and continue to work. When the device is fully maintained, it will enter the standby state again.
