In detail, a stabilizing ring is fixedly connected to the outside of the discharge pipe 45, and a universal wheel is connected to the bottom end of the stabilizing ring through a column.

Example 2 like Figure 1 to Figure 9 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a method for using a shaftless screw conveyor for feed that prevents material from caking, and the steps are as follows: In the first step, the spiral feeding piece 3 is driven to rotate by the driving motor 5 to convey the feed inside the feeding box 1 to the discharge assembly 10, and the feed is discharged through the discharge assembly 10; More specifically, the drive motor 5 is started to provide power to the reduction box 4, so that the reduction box 4 drives the carrying plate 2 connected thereto to rotate, and the carrying plate 2 and the spiral feeding piece 3 are connected so that the spiral feeding piece 3 can rotate inside the feeding box 1. When the feed is placed inside the feeding box 1, the feed can be transmitted to the discharge pipe 45 through the structural characteristics of the spiral feeding piece 3, and finally discharged from the feeding box 1 through the discharge pipe 45; During the use of the discharge pipe 45, the eccentric plate 48 is driven to rotate by the transmission shaft 47. Since the linkage rod 53 is connected between the eccentric plate 48 and the linkage ear 51, when the eccentric plate 48 rotates, the linkage rod 53 can be used to pull the displacement rod 49 to cause the contact plate 50 to leave the ground. Then, the discharge pipe 45 can be rotated to adjust the discharge position of the discharge pipe 45. After the adjustment, the transmission shaft 47 is stopped. Since the linkage ear 51 can stretch the coil spring 52 when it is displaced, the linkage ear 51 can be pulled by the coil spring 52 to cause the contact plate 50 to contact the ground again, thereby positioning the discharge pipe 45. In this way, the discharge position of the feed can be conveniently controlled without adjusting the feed box 1. In the second step, the spiral feeding pieces 3 of one section of the two transmission wheels 21 are brought into contact, and the displacement frame 8 is driven by the spiral feeding pieces 3 to move outside the linear slide bar 7; In more detail, when the feed is transported, the transmission shaft 14 is first rotated to prompt the transmission worm 15 to shift the matching worm wheel 16, and then the carrying plate 12 is turned over through the support shaft 11, so that the carrying frame 17 is close to the spiral feeding piece 3, and then the transmission screw 18 is rotated, and the transmission screw 18 is connected with the carrying frame 17, so that the transmission screw 18 drives the corresponding cleaning frame 19 to move, until the two transmission wheels 21 are tightly fitted with the surface of the spiral feeding piece 3, and then the spiral feeding piece 3 is driven to rotate through the reduction box 4. Since the transmission wheel 21 is in contact with the spiral feeding piece 3 and cooperates with the structural characteristics of the spiral feeding piece 3, when the spiral feeding piece 3 rotates, the displacement frame 8 can be driven to move along the spiral direction of the spiral feeding piece 3 through the transmission wheel 21; The third step is to supply liquid to the material removal nozzle 20 through the water supply pipe 29, and to block the air generation pipe 30 through the driving motor 36 to wash the feed on the surface of the spiral feeding piece 3; In more detail, the external liquid supply pipeline is connected to the water supply pipeline 29, and then the driving motor 36 is started to drive the central shaft 35 to rotate, and the connection between the central shaft 35 and the guide plate 37 is coordinated so that the guide plate 37 can rotate with the central shaft 35, so as to pull the guide slide bar 31 corresponding to the water supply pipeline 29 upward through one of the guide grooves 38 to release the blockage of the water supply pipeline 29, and push the linkage pin 33 corresponding to the wind-generating pipeline 30 downward through another guide groove 38 to block the wind-generating pipeline 30 through the blocking plate 32, and then the external liquid will enter the transmission pipeline 25 and the diversion pipeline 26 through the water supply pipeline 29, and be injected into the de-feeding nozzle 20 through the diversion of the transmission pipe 27, and finally sprayed to the surface of the spiral feeding sheet 3 through the nozzle 22, so as to wash the feed attached to the surface of the spiral feeding sheet 3 to prevent the feed from sticking to the surface of the spiral feeding sheet 3; In the fourth step, air is supplied to the material removal nozzle 20 through the transmission fan 39, and the water supply pipe 29 is blocked by the driving motor 36 to dry the water stains on the surface of the spiral feeding sheet 3; In more detail, after flushing, the drive motor 36 is started again to cause the guide slide bar 31 corresponding to the water supply pipe 29 to move downward, and the water supply pipe 29 is blocked with the help of the blocking piece 32. At the same time, the blocking piece 32 corresponding to the wind-generating pipe 30 will move up at the same time to release the blockage of the wind-generating pipe 30, and then the transmission fan 39 is started to inject the external airflow into the transmission pipe 27 through the transmission pipe 25 and the diversion pipe 26, and send it to the de-materializing nozzle 20 through the transmission pipe 27, and finally spray it to the surface of the spiral feeding sheet 3 through the de-materializing nozzle 20, so as to dry the water stains on the surface of the spiral feeding sheet 3, so that the spiral feeding sheet 3 can be put into use faster, and before the airflow enters the transmission pipe 25, the impurities in the airflow can be blocked by the baffle 40. When the application effect of the baffle 40 is not good, the blocking plate 43 is pulled to make the blocking plate 43 rotate under the support of the support column 42 to release the blockage of the baffle 40, and then the baffle 40 can be removed.
