The working principle and the working method of the transportation device for the bridge construction materials in the embodiment are as follows:
first, the second motor 200 is turned on, the second motor 200 drives the driving shaft 220 to rotate around its axis in the first circumferential direction through the first bevel gear 251 and the second bevel gear 261, and the driving shaft 220 drives the helical blade 140 to rotate when rotating. The materials are put into the feed inlet 100, are spirally driven upwards under the action of the flood dragon mechanism, and are discharged from the discharge outlet 120. In this state, the scraper 230 is rotated in the first circumferential direction along the first ring groove by the slider 231.
If the feeding of the material into the feeding hole 100 is stopped, at this time, the material inside the conveying pipeline 110 is difficult to be conveyed upwards under the influence of gravity, at this time, the first motor 240 is started, so that the first motor 240 drives the first screw 250 to rotate, the first screw 250 drives the second screw 260 to rotate through the first bevel gear 251 and the second bevel gear 261, the first screw 250 drives the first adjusting block 270 to move towards the side far away from the vertical groove along the first screw 250 when rotating, and the first adjusting block 270 drives the transverse stopping block 280 to move towards the side far away from the vertical groove in the horizontal installation groove when moving, so that the connecting channel between the vertical groove and the first ring groove is opened. Meanwhile, the second screw 260 drives the second adjusting block 271 to move downwards when rotating, the second adjusting block 271 drives the longitudinal stop block 281 to move downwards to intercept the rotation of the sliding block 231 in the first ring groove, when the sliding block 231 moves to contact with the longitudinal stop block 281 along with the rotation of the spiral blade 140, the longitudinal stop block 281 and the spiral blade 140 rise along the vertical groove under the limitation until the sliding block 231 enters the second ring groove, and finally, the sliding block rotates along the second ring groove in the first circumferential direction under the driving of the spiral blade 140. When the sliding block 231 moves upwards along the vertical slot, the scraper 230 pushes the material in front to move upwards spirally, and the inside of the conveying pipe 110 is gradually discharged from the discharge hole 120. When the sliding block 231 enters the second annular groove and drives the scraper 230 to rotate to the discharge hole 120 along the second annular groove in the first circumferential direction, the material on the front side of the scraper 230 is completely discharged.
During the ascending process of the scraper 230, the spiral ring strip 232 slides along the edge of the spiral blade 140, and the outer edge of the spiral ring strip 232 contacts with the inner wall of the conveying pipe 110, so when the scraper 230 cleans the material on the spiral blade 140, the material scraped by the scraper 230 does not fall below the scraper 230.
When the material on the spiral blade 140 is completely discharged, that is, after the scraping plate 230 completely passes through the discharging hole 120, the second motor 200 is rotated reversely, so that the driving shaft 220 and the spiral blade 140 rotate in the second circumferential direction, the spiral blade 140 rotates in the second circumferential direction, the sliding block 231 is driven to rotate in the second circumferential direction in the second ring groove, when the sliding block 231 rotates to contact with the one-way stop block 282, the sliding block cannot rotate under the action of the one-way stop block 282, and then the sliding block enters the vertical groove under the action of the spiral blade 140 and the one-way stop block 282, slides downwards along the vertical groove, and then enters the first ring groove.
When the slider 231 enters the first ring groove, the first motor 240 is reversely activated, so that the lateral and longitudinal stoppers 280 and 281 are reset. If scraper blade 230 carries the residual material in the downward movement process, scraper blade 230 pushes away the residual material to guide board 301 department along the in-process of first annular rotation, later during the material gets into residue collecting bin 300 along guide board 301, regularly clear up the residue of residue collecting bin 300 inside can.
