The principles of the present invention are now described as follows:
as shown in fig. 1, in the ditching process, as the ditching device excavates and throws soil, more soil and dust exist in the ditching environment, air carrying soil and dust in the environment passes through the gauze on the square net rack 6 of the dustproof device 3, wherein most of the soil and dust are blocked by the gauze to form a filtering effect, the work load of the air filter 2 is reduced, and the service life of the air filter is prolonged; the area enclosed by the square net rack 6 and the gauze is larger than the area of the air inlet port of the air inlet pipe 1, so that the air circulation resistance caused by the gauze is reduced, and compared with the traditional method of directly binding the gauze at the port of the air inlet pipe 1, the air inlet effect is better;
as shown in fig. 3, if the gauze on the square net rack 6 is blocked by soil and dust to cause failure, the air intake rate in the air intake pipe 1 is reduced, at this time, the rotation speed of the detection blade 54 which is rotatably connected to the cross 51 on the clamping frame 4 in the air intake pipe 1 is reduced, the rate of cutting the detection coil 521 in the rotation groove 52 in the cross 51 by the magnetic field generated by the permanent magnet 531 on the rotation shaft 53 which is coaxially and fixedly connected to the detection blade 54 is reduced, and further, the induced current in the detection coil 521 is reduced, and the control circuit which is electrically connected to the detection coil 521 controls the friction plate 822 to release the fixation of the net collecting shaft 82 at this time;
as shown in fig. 5, at the same time, when the agricultural machine moves, the fan blade 95 is driven by wind to rotate, the fan blade shaft 94 rotates on the fan blade frame 93, the driving shaft 92 rotates through the engagement of the second bevel gear 941 on the fan blade shaft 94 and the first bevel gear 921 on the driving shaft 92, the driving shaft 92 rotates to accumulate elastic potential energy in the coil spring 91 fixedly connected with the driving shaft 92, and therefore, no additional driving device is needed to be applied;
therefore, the net winding shaft 82 rotates to wind the gauze when the coil spring 91 releases the elastic potential energy, the invalid gauze leaves the square net rack 6 and is replaced by the non-invalid gauze on the net releasing shaft 72, the effect of automatically replacing the gauze is formed, the influence of the invalidation of the gauze in the ditching work is avoided, and the work load of frequently dismounting, replacing and cleaning the gauze by workers is reduced;
as shown in fig. 2, when a failed screen enters the screen collecting box 8, the scraper 812 slidably connected in the sliding groove 811 formed in the second opening 81 of the screen collecting box 8 scrapes off soil and dust attached to the surface of the screen, so as to reduce the soil and dust from entering the screen collecting box 8 and improve the tightness of the screen on the screen collecting shaft 82 in the screen collecting box 8;
in addition, the scraper 812 is subjected to the resistance of soil and dust scraped by the scraper, the spring 813 fixedly connected with the scraper is slidingly extruded along the sliding groove 811, the piezoelectric piece 814 is extruded, a potential difference is generated after the piezoelectric piece 814 is extruded, the control circuit receives the electric signal, if the control circuit does not receive the electric signal of the piezoelectric piece 814 for a long time in the working process of controlling the friction plate 822 to be loosened by the control circuit, the air inlet efficiency in the air pipe 1 is still low after the gauze is replaced, and at the moment, the control circuit controls the warning lamp 10 to light up to remind a worker that the air filter 2 needs to be cleaned or replaced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
