[0036] ​The water pump 15 is installed on the blank forming table 1, the end of the water pump 15 is connected with the circulating water tank 17, the other side is connected with the cleaning pipeline 16, the cleaning pipeline 16 is used for cleaning the fixed area, and the mold for ending the blanking is timely flushed, and for the cloth mold cover 9, the length is limited, and the cloth mold cover 9 needs to be processed separately through the mold cover cleaning machine 11, the concrete excess material of the mixer 4 chute 13 falls into the collecting tank 3 for further processing, and the concrete excess material of the material conveying hopper, the cloth hopper 6 and the cloth mold cover 9 falls into the groove;

[0037] The sand chain plate machine 10 is moved, and then the spiral feeding machine 12 is used to send the concrete excess material into the crushing and grading mechanism 14 for screening treatment, so that the classified qualified raw material sand and stone can be obtained and can be used for subsequent pipe pile production, if the crushing and grading mechanism 14 needs to be stopped for maintenance, the spiral feeding machine 12 is not started, and at this time, the concrete excess material is scraped to the collecting tank 3 for storage after the spiral feeding machine 12;

[0039] In embodiment 2, a small part of the sand and stone discharged into the crushing and grading mechanism 14 is caked, and the crushing and grading mechanism 14 adopts a drum screening mode, the residual caked material is crushed online, and the overall sand and stone recovery rate is improved, as shown in the drawing, the main frame 141 has two layers, the top is provided with a rolling crushing drum 143, and the bottom is provided with a movable sieve box 142 moving left and right, and the spiral feeding machine 12 is provided with a discharging assembly 19 corresponding to the side of the crushing drum 143; Figure 3

[0040] As shown in the drawing, the discharging assembly 19 is installed on the frame 141 on one side of the crushing drum 143 and is movably connected with the frame 141, the top opening is used for discharging the sand material, and the sidewall motor is connected with the material winding blade, the sand material is sent into the crushing drum 143 while rotating, and falls into the crushing drum 143 through the groove; Figure 8 As shown in the drawing, the discharging assembly 19 is installed on the frame 141 on one side of the crushing drum 143 and is movably connected with the frame 141, the top opening is used for discharging the sand material, and the sidewall motor is connected with the material winding blade, the sand material is sent into the crushing drum 143 while rotating, and falls into the crushing drum 143 through the groove;

[0041] Figure 9 As shown in the drawing, the discharging assembly 19 is installed on the frame 141 on one side of the crushing drum 143 and is movably connected with the frame 141, the top opening is used for discharging the sand material, and the sidewall motor is connected with the material winding blade, the sand material is sent into the crushing drum 143 while rotating, and falls into the crushing drum 143 through the groove; Figure 8 ​​It is understood that the broken drum 143 gear same side is also provided with temporary storage hopper 20, temporary storage hopper 20 is located in the broken drum 143 inside and outside unfolding, for taking the large particle agglomerate which is not sieved in the process of broken drum 143 rotation, because temporary storage hopper 20 is movably connected with broken drum 143, and one side is provided with pulley, need to set up independent driving source drive;

[0042] At the same time, the temporary storage hopper 20 is also provided with a slideable top column 21, and the top column 21 is uniformly provided with an extrusion crushing block 22 inside the broken drum 143. The agglomerate falling between the two is crushed by the unilateral movement of the top column 21 and the impact of the extrusion crushing block 22, realizing online crushing in the process of agglomerate screening.

[0043] But if the crushed agglomerate cannot be discharged from the temporary storage hopper 20, the material continues to be fed into the reversed broken drum 143, the agglomerate between the extrusion crushing blocks 22 gradually increases, and the impact crushing effect decreases linearly. At this time, the broken agglomerate in the temporary storage hopper 20 needs to be discharged.

[0044] As shown in Figure 8 and Figure 9 The entire drive shaft 262 is movably sleeved with a ratchet sleeve 261, the inner wall of the ratchet sleeve 261 is provided with a tooth pattern, and the outer side of the ratchet sleeve 261 is sleeved with a belt and a belt pulley at the end of the temporary storage hopper 20.

When rotating clockwise, the stop block 264 extrudes the spring 265, so that the entire ratchet sleeve 261 cannot be driven to rotate. The end gear of the drive shaft 262 can drive the entire broken drum 143 to rotate through the linkage gear shaft 23, so that the temporary storage hopper 20 does not move while the entire broken drum 143 rotates, completing the feeding work of the unscreened agglomerate into the temporary storage hopper 20. At this time, the extrusion crushing block 22 on the top column 21 realizes the crushing of the entire agglomerate.

[0046] When discharging is needed, the drive shaft 262 rotates counterclockwise at this time, driving the entire ratchet sleeve 261 to rotate, and the entire temporary storage hopper 20 rotates at the same time. The broken drum 143 and the temporary storage hopper 20 rotate at the same time, completing the discharge work of the broken agglomerate. The ratio of forward and reverse rotation time is usually controlled at 5:1. In one minute of rotation time, 50 seconds are forward rotation and 10 seconds are reverse rotation.

[0047] For the movement of the top column 21 in the temporary storage hopper 20 and reset, its own in the temporary storage hopper 20 is provided with multiple spring 265 abutment, in addition to extrusion broken block 22 impact area, temporary storage hopper 20 will be set up to close the shell, to avoid the agglomeration of falling in the extrusion area, hinder the movement of the top column 21, wherein the top column 21 one end is located outside the broken drum 143, the rack 141 is also movably connected with the ring group 24;

[0048] As Figure 5 and Figure 6 The ring group 24 is composed of gear and turntable, the gear segment ring group 24 is driven to rotate by the linkage shaft 23, and the side wall of the turntable segment is not flat, and is provided with a protrusion, and the abutment rod 25 is rotatably connected to the rack 141, as Figure 4 As shown in the figure, with the rotation of the ring group 24, the protrusion on the turntable contacts the abutment rod 25, and the other side of the abutment rod 25 contacts the top column 21, so as to push the top column 21 to move in the temporary storage hopper 20, realize the automatic crushing of the agglomerated material in the rotating process, compared with the external discharge type screening and crushing, the overall sandstone agglomerate treatment efficiency is higher;

[0049] For the continuously falling screening concrete waste on the broken drum 143, the rack 141 is also provided with a movable sieve box 142, the bottom screen aperture is adjusted according to the specification of the recycled concrete waste, if the requirement is low, the movable sieve box 142 can not be started, and the crushed material screened out by the broken drum 143 is directly taken, if the requirement is high, the crankshaft is driven to rotate by the motor, as Figure 7 As shown in the figure, the movable swing rod 18 is sleeved on the crankshaft to pull the movable sieve box 142 to move left and right, the fine selection of the material after primary crushing and screening is completed, the screened material falls into the secondary material box 145, and the unfiltered material falls into the primary material box 144, and different diameter of the crushed material particles are used for different purposes.
