In the technical scheme, in the process of downward movement of the auxiliary cylinder, on one hand, the contact area between the screw rod and the material in the auxiliary cylinder is increased, so that the material can be dredged better; on the other hand, when the auxiliary cylinder moves downwards, the sliding shaft 65 is driven to slide towards the inside of the shaft sleeve 62, the first anti-blocking assembly 2 pushes the transmission shaft 651 to slide towards the inside of the shaft hole 621 until the driving block 622 is contacted with the transmission block 652, so that the shaft sleeve can drive the sliding shaft to rotate, the sliding shaft drives the driving ring to rotate through the inner gear and the toothed ring, and then the auxiliary cylinder vibrates up and down in the feeding cylinder to assist in discharging.
Under the synchronous action of the first anti-blocking component and the second anti-blocking component, materials in the auxiliary cylinder fall down rapidly, when the supporting component 3 supports the first anti-blocking component 2 upwards and the auxiliary cylinder 11 is reset, the first anti-blocking component 2 drives the transmission shaft 651 to move upwards in the shaft hole 621 again, so that the driving block 622 and the transmission block 652 are not contacted any more, namely, in the case, the feeding is assisted only by the rotation of the screw rod in the second anti-blocking component, and energy conservation is facilitated.
Referring to fig. 1, the embodiment of the application discloses a screw conveyor, which comprises the plugging structure and further comprises a feed cylinder 7, wherein a feed inlet 71 is formed in the top of one end of the feed cylinder 7, the feed inlet 71 is fixedly arranged at the bottom of the feed cylinder 1, a discharge pipe 72 is fixedly arranged at the bottom of the other end of the feed cylinder 7, a screw conveying rod 73 is rotatably arranged in the feed inlet 71, and one end of the screw conveying rod 73 is linked with a bevel gear a 51.
When the driving motor 5 runs, the spiral conveying rod 73 can be driven to rotate in the conveying cylinder 7, so that conveying work of the spiral conveying rod 73 is realized, and meanwhile, the driving motor 5 drives the first anti-blocking component 2 and the second anti-blocking component 4 to perform anti-blocking work on the auxiliary cylinder 11 so as to ensure stability of concrete conveying.
Referring to fig. 1, the apparatus further includes a sensor 75, wherein the sensor 75 is fixedly disposed on top of the auxiliary plate 74, the auxiliary plate 74 is fixedly disposed on top of the feed delivery cylinder 7, and the sensor 75 is disposed on top of the hopper 12 for detecting a descent distance of the hopper 12.
The descending distance of the hopper 12 is detected by the sensor 75 to judge the discharging condition of the inside of the auxiliary cylinder 11, so as to prevent the feeding to the inside from being continuously carried out when the inside of the auxiliary cylinder 11 is blocked, thereby preventing the conveying fault.
In view of the above, when the screw conveyor disclosed in the embodiment of the application is used, the driving motor 5 is started to drive the screw conveying rod 73 inside the conveying cylinder 7 to rotate, meanwhile, the driving motor 5 drives the bevel gear B61 to rotate through the bevel gear A51, the bevel gear B61 drives the bevel gear C63 and the inner sliding shaft 65 to rotate through the shaft sleeve 62, the bevel gear C63 drives the connecting shaft 43 to rotate through the outer bevel gear D64, and the connecting shaft 43 drives the screw rod 41 to rotate through the gear box 42. That is, under the normal working condition, the driving motor 5 drives the screw conveying rod to convey the material on one hand, and drives the screw rod 41 in the second anti-blocking component to dredge the material in the auxiliary cylinder on the other hand, so that the material is prevented from being blocked.
When more materials are in the auxiliary cylinder, the auxiliary cylinder and the materials in the auxiliary cylinder gradually compress the spring under the action of the materials, and at the moment, the auxiliary cylinder and the materials in the auxiliary cylinder gradually move downwards.
When the auxiliary cylinder moves downwards, on the one hand, the material in the auxiliary cylinder can move towards the screw rod 41, so that the contact area between the material and the screw rod is increased, and the screw rod can dredge the material in the auxiliary cylinder better.
On the other hand, the driving ring 21 pushes down the supporting plate 24 to compress the spring 33 by sliding downwards outside the supporting rod 32, at this time, the first anti-blocking component 2 pushes the transmission shaft 651 to slide towards the inside of the shaft hole 621 until the transmission block 652 contacts with the driving block 622, at this time, the driving motor drives the sliding shaft to rotate through the shaft sleeve and the transmission shaft, so that the sliding shaft 65 drives the toothed ring 25 at the bottom of the driving ring 21 to rotate through the inner gear 66, the toothed ring 25 drives the driving ring 21 to slide at the top of the sliding ring 23, the driving rod 13 is supported upwards by the smooth section at the top of the driving ring 21, when the driving ring 21 drives the driving groove 22 to rotate to the bottom of the sliding ball 14, the auxiliary cylinder 11 pushes the sliding ball 14 to move towards the top of the driving groove 22 under the action of gravity of the auxiliary cylinder 11, so that the auxiliary cylinder 11 vibrates through the impact of the sliding ball 14 and the driving groove 22, after concrete enters the inside the auxiliary cylinder 11 through the hopper 12, the auxiliary cylinder 11 can be driven to vibrate and blanking inside the feeding cylinder 1, and the second anti-blocking component is matched, so that the materials are fast blanking and the blocking is avoided.
In addition, the descending distance of the hopper 12 is detected by the sensor 75 to judge the discharging condition of the inside of the auxiliary cylinder 11, so as to prevent the feeding to the inside from being continuously caused by the conveying fault when the inside of the auxiliary cylinder 11 is blocked.
After the concrete in the auxiliary cylinder 11 is dredged, the spring 33 drives the supporting plate 24 upwards to reset, so that the supporting plate 24 drives the first anti-blocking component 2 and the auxiliary cylinder 11 to reset upwards, at the moment, the auxiliary cylinder 11 moves towards the side far away from the second anti-blocking component 4 again, and the first anti-blocking component 2 drives the transmission shaft 651 to move upwards in the shaft hole 621 until the transmission block 652 is not contacted with the driving block 622, namely, at the moment, the first anti-blocking component does not work any more, and the blocking is only performed through the dredging of the second anti-blocking component, so that the continuous operation of the conveyor is ensured while the energy is saved, and the concrete in the feeding cylinder 7 is conveyed under the action of the spiral conveying rod 73.
