no. 1 example

[0040] Depend on Figure 1 to Figure 4 Given, the present invention includes a body 1, one side of the body 1 is provided with a controller 32, the controller 32 electrically controls each electrical component, the interior of the body 1 is provided with a hopper 33, the bottom of the hopper 33 passes through the body 1 and passes through the electromagnetic The valve is provided with a blanking pipe 2. The solenoid valve can control the opening size of the blanking pipe 2. The asphalt inside the hopper 33 can be directly dropped to the ground along the blanking pipe 2 for subsequent paving work. The bottom of the body 1 is provided with several Fixed block 3, the bottom of the fixed block 3 is provided with a universal wheel 4, the lower part of the body 1 is provided with a scraper 5, and both sides of the scraper 5 are slidably connected with a side baffle 6, and the side baffle 6 and the scraper 5 pass through The adjustment component is connected, and the side baffle 6 ca...

[0051] like Figure 5-7 It can be seen from the first embodiment that, in actual operation, when the hot-melt asphalt in the hopper 33 falls to the ground along the drop tube 2, the volume of the asphalt will decrease due to the principle of thermal expansion and contraction, and further in the spread Paving will cause unevenness of the road surface, and even cause the road surface to crack. At the same time, after a long time of use, the surface of the scraper 5 and the side baffle 6 will adhere to part of the asphalt, which will hinder the subsequent paving work. In order to solve the above problems, improve the degree of thermal expansion and contraction of asphalt under different environmental adjustment, and then ensure the smoothness of pavement paving, and scrape off the asphalt adhering to the surface of the scraper 5 and the side baffle 6 after the paving is completed. , The asphalt paver for municipal roads also includes: a first temperature sensor is arranged inside...

no. 3 example

[0066] like Figure 8 As shown, a construction process of an asphalt paver for municipal roads, the construction process involving an asphalt paver for municipal roads, includes the following steps:

[0067] S1. Move the body 1 to a suitable position, the molten asphalt is placed inside the hopper 33, the controller 32 controls the solenoid valve in the blanking pipe 2 to open, and the asphalt in the hopper 33 falls to the ground along the blanking pipe 2, and the first temperature The sensor detects the temperature value in the blanking tube 2;

[0068] S2. The controller 32 controls the first motor 10 to start, the first motor 10 drives the first threaded column 8 to rotate, the first threaded column 8 rotates to drive the first fixed plate 7 to move upward, and the first fixed plate 7 drives the scraper when moving upward. 5 Move up to adjust the asphalt paving height;

[0069] S3. According to the opening degree of the solenoid valve and the rising height of the scraper ...

Abstract

The invention relates to the technical field of asphalt pavers, and discloses an asphalt paver for municipal roads and a construction technology.The asphalt paver comprises a machine body, a controller is arranged on one side of the machine body, a hopper is arranged in the machine body, and the bottom of the hopper penetrates through the machine body and is provided with a discharging pipe through an electromagnetic valve; a first temperature sensor is arranged in the discharging pipe and used for detecting the temperature value of asphalt flowing out along the discharging pipe, a scraper is arranged below the machine body, a second temperature sensor is arranged on the outer surface of the side, close to the discharging pipe, of the scraper and used for detecting the temperature value of the surface of the scraper, and side baffles are slidably connected to the two sides of the scraper. The side baffle is connected with the scraper plate through an adjusting assembly, so that the problems that the height of the scraper plate for uniformly smearing the asphalt is inconvenient to adjust, the asphalt is often not uniformly smeared, and the expansion caused by heat and contraction caused by cold during paving of the asphalt cannot be adaptively adjusted are solved; and meanwhile, asphalt residues left on the surfaces of the scraping plate and the movable plate cannot be thoroughly removed.

Description

technical field [0001] The invention belongs to the technical field of asphalt paver, in particular to an asphalt paver for municipal roads and a construction technique. Background technique [0002] Pavement machinery is a kind of machinery used in civil engineering to build highways, urban road pavements and airport pavements. Asphalt paver is a relatively common type of pavement machinery. An asphalt paver is required. [0003] A machine that evenly spreads the asphalt mixture on the road base, and conducts preliminary vibrating and leveling. There are two types of crawler type and tire type. It consists of two parts: traction, paving, vibrating and ironing. The former includes frame, power unit, traveling device, body, material door, scraper conveyor, screw spreader and cab, etc. The latter includes the pulling arm, the tamping mechanism and the ironing device. [0004] Chinese invention patent CN2021100616780 relates to a manual asphalt paver, comprising a frame pr...
