[0014] The beneficial effects of the present invention are as follows: In the present invention, for the integrated device for salt dust recovery and self-cleaning of a sea salt transportation carriage, by starting the electric push rod to drive the installation shell to move downward, the cleaning brush moves downward, so that the cleaning brush contacts the inner wall of the bottom of the outer carriage 1. Then, the driving motor and the air extraction pump are started. The driving motor drives the active pulley to rotate. The active pulley drives the driven pulley to rotate through the belt. The driven pulley drives the connecting pipe and the cleaning wheel to rotate. The cleaning wheel drives the cleaning brush to rotate, so as to clean the salt dust on the inner wall of the bottom of the outer carriage. At the same time, when the air extraction pump is started, negative pressure is generated in the dust collection box, so that part of the air and salt dust in the installation shell enter the dust collection box through the connecting elbow pipe, and the other part enters the inside of the cleaning wheel through the through hole, and enters the dust collection box through the connecting pipe, the ventilation hole, the vertical square pipe and the horizontal square pipe. After the cleaning brush hits the blocking rod, the salt dust shakes off and enters the dust collection box along the connecting elbow pipe, and then the salt dust is filtered and collected through the filter screen; In the present invention, for the integrated device for salt dust recovery and self-cleaning of a sea salt transportation carriage, when there is negative pressure in the dust collection box, the sealing disc balances the internal pressure of the sealing cylinder, so as to squeeze the second pressure sensor. Thus, the negative pressure levels on both sides of the filter screen are monitored by two negative pressure monitoring mechanisms, and the pressure difference is calculated. During the process of filtering salt dust, the filter screen will be subjected to a downward thrust of air, so as to squeeze the first pressure sensor. As the salt dust accumulated on the filter screen increases, the pressure value monitored by the first pressure sensor gradually increases. Thus, by synthesizing the value of the first pressure sensor and the difference between the two second pressure sensors, the delayed collection and accumulation status of the dust on the filter screen can be judged, and the operating power of the air extraction pump can be adjusted in real time to ensure sufficient air intake and dust suction speed; In the present invention, for the integrated device for salt dust recovery and self-cleaning of a sea salt transportation carriage, by starting the rotary motor to drive the worm to rotate, the worm drives the connecting shaft and the gear to rotate through meshing with the worm gear, and the gear drives the moving plate to move through meshing with the rack, thereby driving the dust suction mechanism and the cleaning mechanism to move horizontally, so as to perform full-automatic cleaning on different positions; In the present invention, for the integrated device for salt dust recovery and self-cleaning of a sea salt transportation carriage, the increase rate of salt dust on the filter screen can be judged by comprehensively considering the value of the first pressure sensor and the change of the difference between the two second pressure sensors, and the power of the rotary motor can be adjusted in real time according to the increase rate of salt dust. When the increase rate of dust increases, the rotation speed of the rotary motor is controlled to decrease, so as to enhance the dust adsorption effect on some areas. When the pressure value monitored by the upper second pressure sensor exceeds the preset value, it can be checked whether there is a blockage inside the device; In the present invention, for the integrated device for salt dust recovery and self-cleaning of a sea salt transportation carriage, by rotating the rotary handle to drive the rotating arm to rotate, the rotating arm drives the two buckles to move away from each other through two linkage rods, and then horizontally pulls the pull frame to drive the collection box to be pulled out of the dust suction box, so as to facilitate the cleaning of the dust on the filter screen; In the present invention, for the integrated device for salt dust recovery and self-cleaning of a sea salt transportation carriage, through the driving mechanism, the cleaning mechanism and the dust suction mechanism, automatic recovery of salt dust and automatic cleaning of the carriage can be realized, and real-time adjustment can be made through the set negative pressure monitoring mechanism and pressure monitoring mechanism to improve the efficiency of salt dust recovery and cleaning.

[0027] In this embodiment, during use, by starting the electric push rod 202 to drive the installation shell 4 to move downward, the cleaning brush 501 moves downward, so that the cleaning brush 501 contacts the inner wall of the bottom of the outer carriage 10. Then, the drive motor 601 and the air extraction pump 11 are started. The drive motor 601 drives the driving pulley 602 to rotate. The driving pulley 602 drives the driven pulley 603 to rotate through the belt. The driven pulley 603 drives the connecting pipe 503 and the cleaning wheel 5 to rotate.

Thus, the negative pressure levels on both the upper and lower sides of the filter net 303 are monitored by two negative pressure monitoring mechanisms 9, and the pressure difference is calculated. During the process of filtering salt dust, the filter net 303 is subjected to a downward thrust of air, thereby squeezing the first pressure sensor 703. As the salt dust accumulated on the filter net 303 increases, the pressure value monitored by the first pressure sensor 703 gradually increases. Thus, by synthesizing the value of the first pressure sensor 703 and the difference between the two second pressure sensors 902, the delayed collection and accumulation status of the dust on the filter net 303 can be judged, and the operating power of the air extraction pump 11 can be adjusted in real time to ensure sufficient air intake and dust suction speed. By starting the rotary motor 208 to drive the worm 207 to rotate, the worm 207 drives the connecting shaft 205 and the gear 204 to rotate through meshing with the worm gear 206. The gear 204 drives the moving plate 201 to move through meshing with the rack 203, thereby driving the dust suction mechanism 3 and the cleaning mechanism to move horizontally, so as to perform full-automatic cleaning on different positions. By synthesizing the change situation of the value of the first pressure sensor 703 and the difference between the two second pressure sensors 902, the increasing speed of the salt dust on the filter net 303 can be judged, and the power of the rotary motor 208 can be adjusted in real time according to the increasing speed of the salt dust. When the increasing speed of the dust increases, the rotation speed of the rotary motor 208 is controlled to decrease, thereby strengthening the dust adsorption effect on some areas. When the pressure value monitored by the second pressure sensor 902 above exceeds the preset value, it can be checked whether there is a blockage inside the device. By rotating the handle 805 to drive the rotating arm 806 to rotate, the rotating arm 806 drives the two buckles 802 to move away from each other through two linkage rods 804, and then horizontally pulls the pulling frame 808 to drive the collection box 302 to be pulled out from the dust suction box 301, so as to facilitate the cleaning of the dust on the filter net 303.
