The specific working process is as follows: when the temporary sand screening machine designed by the invention is used, the sand screening machine is moved to a designated position before use, then the rear bracket 3 on the sand screening machine is opened, when the two clamping blocks 18 arranged on the rear bracket 3 are contacted and clamped with the two limiting blocks 17 arranged on the mounting frame 10, as shown in fig. 28, the rear end of the sand screening machine is inserted into unfiltered sand, the sand screening machine can be normally used, then the driving motor 2 is started, so that the driving motor 2 drives the second synchronizing wheel 15 to rotate, and the second synchronizing wheel 15 rotates to drive the first synchronizing wheel 14 to rotate through the first synchronous belt 13; the first synchronous wheel 14 rotates to drive one fixed rotating shaft 11 positioned at the upper side of the two fixed rotating shafts 11 to rotate, the fixed rotating shaft 11 rotates to drive the corresponding roller 4 to rotate, the roller 4 rotates to drive the transmission belt 1 to rotate, the transmission belt 1 rotates to drive the other roller 4 to rotate on the one hand, on the other hand, the transmission belt 1 rotates to drive unfiltered sand inserted into sand on the transmission belt 1 to rotate together, when the sand starts to be driven to rotate, because the barrier strip 37 at the lower side of the transmission belt 1 where the sand is positioned is limited by the shielding plate 6, the filtering hole 38 matched with the barrier strip 37 on the transmission belt 1 cannot be opened, in this state, the sand is driven by the transmission belt 1 to move upwards, and when the transmission belt 1 part where the sand is positioned is staggered with the shielding plate 6, the shielding plate 6 loses the limiting effect on the barrier strip 37 at the lower side of the transmission belt 1, on one hand, the shielding plate enables the corresponding barrier strip 37 to swing downwards under the action of the gravity of the shielding plate and the action of pressing down of sand filtered by the filtering holes 38, and the filtered sand flows into the upper side of the barrier strip 37 mounted on the lower conveying belt 1 through the upper conveying belt and moves along with the lower conveying belt; when the upper side transmission belt presses the swing barrier strip 37 to be contacted with the roller 4 at the upper end in the rotating process, the roller 4 at the upper end extrudes the barrier strip 37 to enable the barrier strip to swing and reset, and when the barrier strip 37 rotates to the lower side through the roller 4 at the upper end, the barrier strip 37 is tightly attached to the inner wall of the transmission belt 1 under the action of gravity to block the filtering holes 38 at the lower side of the transmission belt 1, sand cannot flow into the ground at the lower side of the transmission belt 1 through the filtering holes 38 at the lower side of the transmission belt 1, so that a certain distance is kept between the filtered sand and the unfiltered sand, and the mixing is avoided; when the filtered sand flows into the upper side of the barrier strip 37 installed on the lower side transmission belt 1, the transmission belt 1 drives the filtered sand to move in the rotating process, and when the filtered sand on the lower side transmission belt 1 contacts with the flow guide block 8, as shown in fig. 28, the sand is pushed to the ground on the two sides of the transmission belt 1 under the action of the flow guide block 8, so that a filtered sand pile is easily formed and is convenient to use; the filtered coarse sand and stones are driven to the uppermost side by the transmission belt 1 and fall to the ground from the uppermost side of the transmission belt 1; after a period of use, the unfiltered sand is reduced, and the sand on the conveyor belt is correspondingly reduced, so that the surrounding unfiltered sand needs to be manually piled up to a position where the conveyor belt 1 can convey, or the sand screening machine can be directly moved to insert the rear end of the sand screening machine into the unfiltered sand.
When one fixed rotating shaft 11 positioned at the upper end of the two fixed rotating shafts 11 rotates, the fixed rotating shaft 11 can drive a fourth synchronizing wheel 26 arranged on the fixed rotating shaft to rotate, the fourth synchronizing wheel 26 rotates to drive a third synchronizing wheel 22 to rotate through a second synchronous belt 23, the third synchronizing wheel 22 rotates to drive a first rotating shaft 21 to rotate, the first rotating shaft 21 rotates to drive the two first bevel gears 20 to rotate, and when a toothed region on one first bevel gear 20 of the two first bevel gears 20 is meshed with a corresponding second bevel gear 27, a tooth-missing region 30 on the other first bevel gear 20 is in a matching state with the corresponding second bevel gear; therefore, when two first bevel gears 20 rotate, the first bevel gear 20 engaged with the second bevel gear 27 drives the corresponding second bevel gear 27 to rotate, the second bevel gear rotates to drive the corresponding second rotating shaft 29 to rotate, the second rotating shaft 29 rotates to drive the corresponding driving wheel 19 to rotate, the driving wheel 19 rotates to drive the corresponding telescopic swing rod 28 to swing, the telescopic swing rod 28 swings to drive two fixing plates 34 to move, the two fixing plates 34 move to drive the two rollers 4 to move on the two fixed rotating shafts 11, the two rollers 4 move to drive the transmission belt 1 to move along the axis of the rollers 4 in one direction, when the tooth-missing region 30 on the first bevel gear 20 engaged with the second bevel gear 27 originally is engaged with the second bevel gear 27, the tooth-carrying region on the other first bevel gear 20 is engaged with the corresponding second bevel gear 27, in this state, the belt 1 is moved in the opposite direction along the axis of the roller 4, and is sequentially transferred, and the belt 1 is driven to move back and forth along the axis of the roller 4 while rotating, that is, the belt 1 has a vibration function, and the efficiency of filtering sand by the belt 1 is improved by the vibration.
In summary, the following steps:
compared with the traditional sand screening machine, the temporary sand screening machine designed by the invention has the advantages that the size is smaller, the carrying is convenient, and when the temporary sand screening machine is used, the rear bracket 3 is opened and supported, so that a certain included angle is formed between the transmission belt 1 for filtering sand and the ground; when the sand screening machine is not used, the rear support 3 is folded, so that the sand screening machine is in a flat plate shape and is convenient to carry and transport; the temporary sand screening machine designed by the invention has the advantages that the rear bracket 3 is directly opened and supported when the temporary sand screening machine is used, other additional operations are not needed, the sand screening mechanism is convenient to operate, and meanwhile, the sand screening mechanism is convenient to arrange when in use; when the temporary sand screening machine designed by the invention is used, the lower end of the sand screening mechanism is directly inserted into sand, the sand is automatically transferred onto the transmission belt 1 through the rotation of the transmission belt 1 in the working process, the sand is filtered through the transmission belt 1, after the temporary sand screening machine is used for a period of time, the unfiltered sand is reduced, the sand on the transmission belt is correspondingly reduced, at the moment, the surrounding unfiltered sand needs to be manually piled up to the position where the transmission belt 1 can transmit, the sand screening machine can also be directly moved, and the rear end of the sand screening machine is inserted into the unfiltered sand. The use is more labor-saving.
