Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a mud scraping device for an engineering vehicle washing machine includes a gantry 1, a motor 2 is fixed on the right side of the gantry 1, a bidirectional threaded rod 3 is fixed to the output end of the motor 2, the bidirectional threaded rod 3 is connected to the gantry 1 by a bearing, and a cross bar 4 fixed to the gantry 1 is arranged below the bidirectional threaded rod 3; a fixed block 5 is connected to the cross bar 4, an electric telescopic rod 6 is fixed to the lower end of the fixed block 5, a fixed plate 7 is fixed to the output end of the electric telescopic rod 6, a movable plate 8 is arranged below the fixed plate 7, and a scraper 10 is fixed to the lower end of the movable plate 8 by bolts.

[0022] The cross bar 4 and the two-way threaded rod 3 are parallelly distributed, and the cross bar 4 and the fixed block 5 are slidably connected. When the fixed block 5 moves, the sliding guiding effect between the fixed block 5 and the cross bar 4 can ensure the stability of the movement of the fixed block 5; a protrusion 501 is also fixed to the upper end of the fixed block 5, and the protrusion 501 is threadedly connected to the two-way threaded rod 3. Through the above structure, a basic force can be provided for the movement of the fixed block 5, thereby providing a basic guarantee for the width adjustment of the two scrapers 10; two scrapers 10 are provided, and the scrapers 10 are staggered front and back, and the scrapers 10 are of an "L"-shaped structure. Through the front and back distribution of the scrapers 10, a basic guarantee can be provided for the width adjustment of the two groups of scrapers 10; a clamping plate 1001 is also fixed on the scraper 10, and the clamping plate 1001 can slide left and right when in contact with another scraper 10. When the width of the two scrapers 10 is adjusted, the sliding guiding effect of the clamping plate 1001 can ensure the stability of the movement of the scraper 10;

[0023] When using the scraper device of the engineering vehicle washing machine, if Figure 1-Figure 4 As shown, firstly, the whole device is installed and powered by an external power supply. When scraping mud and cleaning the engineering vehicle compartment, the width of the two groups of scrapers 10 is adjusted according to the width of the engineering vehicle compartment. By starting the motor 2 to drive the bidirectional threaded rod 3 to rotate, the two groups of fixed blocks 5 can be forced to move with the threaded connection between the bidirectional threaded rod 3 and the protrusion 501, thereby driving the two scrapers 10 to move. With the sliding guide function of the clamping plate 1001, the stability of the movement of the two scrapers 10 can be guaranteed, thereby realizing the width adjustment of the two scrapers 10, so as to meet the scraping and cleaning needs of engineering vehicle compartments with different widths.

[0024] The gantry 1 is also symmetrically fixed with water pipes 101, and high-pressure nozzles 102 are fixed at equal intervals on the lower end surface of the water pipes 101. Through the above structure, the flushing effect of the engineering vehicle compartment can be achieved to ensure the cleaning effect of the engineering vehicle compartment; one end of the spring 801 is also fixed on the movable plate 8, and the other end of the spring 801 is fixed on the fixed plate 7. Through the buffering and protective effect of the spring 801, the scraper 10 can be prevented from causing damage to the engineering vehicle compartment; the movable plate 8 is also symmetrically and vertically fixed with vertical rods 9, and the vertical rods 9 penetrate the fixed plate 7 and can move up and down. When the movable plate 8 moves relative to the fixed plate 7, the sliding guide effect of the vertical rods 9 can ensure the stability of the movement of the movable plate 8;

[0025] After the width adjustment of the two scrapers 10 is completed, Figure 1-Figure 4 As shown, by controlling the extension of the electric telescopic rod 6, the fixed plate 7, the movable plate 8 and the scraper 10 are driven to move downward. When the scraper 10 contacts the engineering vehicle compartment, the elastic effect of the spring 801 can achieve buffer protection, so that the hard contact between the scraper 10 and the engineering vehicle compartment is changed into a flexible structure, avoiding damage to the scraper 10 and the engineering vehicle compartment. Then, water can be supplied to the water pipe 101 through the use of an external water pump and a water pipe. With the action of the high-pressure nozzle 102, the sludge adhered in the engineering vehicle compartment can be washed once. In combination with the tunnel car washing mechanism driving mechanism, the engineering vehicle can be moved slowly, so that the scraper 10 can scrape off the sludge in the engineering vehicle compartment conveniently, thereby achieving a secondary cleaning effect and ensuring the cleaning effect of the sludge in the engineering vehicle compartment. This is the working principle of the mud scraping device of the engineering vehicle washing machine.
