At the same time, the second motor 4021 drives the rotating shaft 4022 to move on the shaft The extension frame 3011 is rotated under the restriction of the bearing 4023, so that the angle of the sand cleaning trough 301 and the dust suction head 5012 is adjusted. The dust suction head 5012 is tilted downward to reduce the overflow of sand and dust, and can better absorb the sand and dust collected by the sand cleaning trough 301, and keep it flush with the inner wall of the sand cleaning trough 301 to ensure that it does not interfere with the movement of the sand cleaning block 302. The accessories such as the dust cover can be disassembled and installed according to the actual use environment to avoid the inhalation of other impurities, and sufficient suction is provided by the sand suction pump body 501, and the sand and dust are extracted from the dust suction head 5012 through the dust suction hard pipe 5011.

[0028] The sand cleaning block 302 is provided with an inclined surface adapted to the sand cleaning groove 301, and a slider 3022 threadedly connected to the screw rod 3031 is fixedly installed on the top of the sand cleaning block 302, and a slide groove for limiting the movement of the slider 3022 is provided on the sand cleaning groove 301, and a sand retaining plate 3021 adapted to the opening 3012 is fixedly installed on one end of the sand cleaning block 302 close to the slide groove, and the inclined surface on the sand cleaning block 302 can better fit the inner wall of the sand cleaning groove 301, and the sand cleaning block 302 When moving, the vehicle body 1 does not move, and no new sand and dust are added to the sand cleaning groove 301, thereby ensuring the normal resetting of the sand cleaning block 302, and the slider 3022 can move in the slide groove, thereby ensuring that the sand cleaning block 302 moves along the length direction of the sand cleaning groove 301, and the probability of sand and dust leaking from the slide groove when the sand cleaning block 302 moves is reduced by the sand baffle 3021, and when the sand baffle 3021 enters the opening 3012, a preliminary cleaning of the sand and dust in the sand cleaning groove 301 is completed.

[0029] The first motor 303 is fixedly mounted on the expansion frame 3011, and one end of the screw rod 3031 is drivingly connected to the output shaft of the first motor 303, and the other end of the screw rod 3031 is rotatably connected to the expansion frame 3011 and is distributed parallel to the rotating shaft 4022. The screw rod 3031 can be driven by the first motor 303 to move the slider 3022, and by being distributed parallel to the rotating shaft 4022, interference with the position during the angle adjustment process is avoided.

[0030] A groove corresponding to the lifting frame 401 is opened on the vehicle body 1, and a lifting block 4011 and a positioning block 4012 are respectively installed on the inner side of the lifting frame 401, and a lifting push rod 4013 and a positioning shaft 4014 corresponding to the lifting block 4011 and the positioning block 4012 and vertically distributed with the vehicle body 1 are fixedly installed in the vehicle body 1, and the piston rod of the lifting push rod 4013 is fixedly connected with the corresponding lifting block 4011, and the positioning shaft 4014 extends to one end outside the vehicle body 1 and penetrates the entire positioning block 4012.

[0031] When used for sand dust adsorption and cleaning of ballastless track high-speed railways in sandy areas, by placing 1 on the track of the high-speed railway, the main body of the vehicle 1 moves along the track. The sand cleaning groove 301 collects the sand dust between the rails. The first motor 303 drives the screw rod 3031 to rotate, and the sand cleaning block 302 moves along the length direction of the sand cleaning groove 301 through the slider 3022, cleaning the sand dust in the sand cleaning groove 301, and reducing the probability of sand dust leaking from the chute when the sand cleaning block 302 moves through the baffle 3021. At the same time, when the baffle 3021 enters the opening 3012, a preliminary cleaning work of the sand dust in the sand cleaning groove 301 is completed. And when the sand cleaning block 302 moves, the main body of the vehicle 1 does not move, so as to ensure the normal reset of the sand cleaning block 302.

[0032] And in this process, the second motor 4021 drives the rotating shaft 4022 to rotate, so that the expansion frame 3011 deflects, thereby adjusting the angles of the sand cleaning groove 301 and the dust suction head 5012. At the same time, the lifting push rod 4013 drives the lifting frame 401 connected to the lifting block 4011 to lift through the change of the piston rod. The positioning block 4012 slides on the positioning shaft 4014 to maintain stability during the lifting process, meeting the sand dust cleaning requirements in different environments, ensuring that the dust suction head 5012 can better fit the track surface, and reducing the spillage of sand dust.

[0033] Embodiment 2 Refer to Figure 1-10 , which is the second embodiment of this application. The difference between this embodiment and the first embodiment is: The sand suction assembly 5 further includes a bucket cover 502 and a sand dust storage bucket 503 located in the equipment cabin 2. And the bucket cover 502 is detachably installed at the top of the sand dust storage bucket 503 through the bolt loading and unloading part 504. The bottom end of the sand dust storage bucket 503 is annularly and arrayedly distributed with legs 5032 fixedly connected to the main body of the vehicle 1. A sand discharge pipe 5031 for discharging sand dust is also installed on the sand dust storage bucket 503. The bucket cover 502 is fixed on the sand dust storage bucket 503 through the bolt loading and unloading part 504, which is convenient for disassembly and installation, and convenient for cleaning and maintenance. The sand dust storage bucket 503 can provide enough space to store sand dust, ensure that the sand dust will not overflow, keep the inside of the equipment cabin 2 clean, and has two sand dust discharge modes by opening the bucket cover 502 and through the sand discharge pipe 5031 at the same time.

[0034] The sand screening assembly 6 includes a sand screening bucket 601 driven by a third motor 6011 and located in the dust storage bucket 503. One end of the dust suction hard pipe 5011 passes through the bucket cover 502 and extends into the sand screening bucket 601. The third motor 6011 is fixedly installed at the bottom end of the dust storage bucket 503. One end of the output shaft of the third motor 6011 extending into the dust storage bucket 503 is in transmission connection with the sand screening bucket 601. The sand screening bucket 601 is also provided with a first sieve hole 6012 for screening dust. The sand screening bucket 601 can be driven by the third motor 6011 to screen the collected dust, separate dust of different particle sizes. The dust larger than the first sieve hole 6012 remains in the sand screening bucket 601 and is taken out by opening the bucket cover 502. The top is communicated with the dust suction hard pipe 5011 to receive the dust collected from the dust suction head 5012.

[0035] A sieve plate 602 driven by a reciprocating sand screening mechanism 603 is sleeved outside the sand screening bucket 601 in the dust storage bucket 503. One end of the sieve plate 602 close to the bucket cover 502 is fixedly installed with a sand retaining edge 6021 which is in clearance fit with the sand screening bucket 601. The sieve plate 602 is also provided with a second sieve hole 6022 with a pore diameter smaller than that of the first sieve hole 6012. The sieve plate 602 can carry the dust filtered by the first sieve hole 6012, and prevent the dust from overflowing through the gap between the sieve plate 602 and the sand screening bucket 601 through the sand retaining edge 6021, ensuring the tightness of the screening process. At the same time, the reciprocating sand screening mechanism 603 makes the sieve plate 602 reciprocate along the axial direction of the sand screening bucket 601, and further screens the dust through the second sieve hole 6022. The screened dust is drawn out through the sand discharge pipe 5031.

[0036] The reciprocating sand screening mechanism 603 includes a fourth motor 6031 fixedly installed in the vehicle body main body 1. The output shaft of the fourth motor 6031 is in transmission connection with a swing arm 6032. One end of the swing arm 6032 is hinged to a connecting rod 6033. The swing arm 6032 is hinged to a reciprocating sliding rod 6034 slidably connected in the dust storage bucket 503 through the connecting rod 6033. One end of the reciprocating sliding rod 6034 away from the connecting rod 6033 is located in the dust storage bucket 503 and is fixedly connected to the sieve plate 602. The swing arm 6032 can transmit the power of the fourth motor 6031 to the connecting rod 6033 to drive the sieve plate 602 to reciprocate under the limitation of the reciprocating sliding rod 6034.

[0037] The vehicle body 1 is also equipped with a track wheel 102 driven by the driving chassis 101 and used for track travel. A control module 201 for controlling the device is provided in the equipment compartment 2. The vehicle body 1 is also provided with a laser detection sensor 202 electrically connected to the control module 201. The control module 201 is used to control the operation of the entire equipment, including the start and stop of each motor, and screening operations, etc. The laser detection sensor 202 monitors the dust situation on the track in real time and provides data support for the control module 201 to ensure the efficient operation of the equipment. The track wheel 102 provides power through the driving chassis 101, so that the equipment can run smoothly on the track. This is common knowledge and technical content of personnel in this field and will not be elaborated here.

[0038] When the sand and dust collected by the dust suction head 5012 enters the sand screening bucket 601 through the dust suction hard pipe 5011, the sand screening bucket 601 is driven to rotate by the third motor 6011, and the sand and dust are preliminarily screened through the first sieve hole 6012 on the sand screening bucket 601. The sand and dust larger than the first sieve hole 6012 remain in the sand screening bucket 601, and can be taken out by opening the bucket cover 502 to complete the preliminarily screening. The preliminarily screened sand and dust fall on the sieve plate 602, and the fourth motor 6031 is connected to the swing arm 6032 through the output shaft transmission, and the swing arm 6032 drives the reciprocating slide bar 6034 to reciprocate through the connecting rod 6033, thereby driving the sieve plate 602 to reciprocate along the axial direction of the sand screening bucket 601. The aperture of the second sieve hole 6022 on the sieve plate 602 is smaller than the first sieve hole 6012, and the sand and dust are further screened. The sand retaining edge 6021 prevents sand and dust from overflowing from the gap between the sieve plate 602 and the sand screening bucket 601, thereby ensuring the sealing of the screening process and completing further screening of the sand and dust.

[0039] The sieved dust is stored in the dust storage barrel 503. The dust storage barrel 503 has enough space to store the dust to prevent the dust from overflowing and keep the equipment compartment 2 clean. The dust can be discharged in two ways: open the barrel cover 502, manually clean the dust on the sand screening barrel 601 and the screen plate 602, or extract the dust through the sand discharge pipe 5031. In this process, the operation of the entire equipment is controlled by the control module 201 in the equipment compartment 2, including the start and stop of each motor, screening operation, etc. At the same time, the laser detection sensor 202 on the vehicle body 1 monitors the dust situation on the track in real time, and feeds back the data to the control module 201. The control module 201 adjusts the operating status of the equipment according to the monitoring data to ensure the efficient operation of the equipment and improve the degree of automation of the device. The track wheel 102 powered by the driving chassis 101 enables the equipment to run smoothly on the track.
