[0036] The material conveying device disclosed by the utility model, the shaft 13 is rotated by the first driving part 4, and the spiral blade 11 on the shaft 13 rotates with the shaft 13, due to the spiral shape of the spiral blade 11, the material in the bin 2 is pushed out gradually and stably under the pushing of the spiral blade 11, and the material moves from the output of the bin 2 to the screening mechanism, after the material enters the screen cylinder 6 from the feeding mechanism, the screen cylinder 6 is inclinedly arranged, the material rolls in the screen cylinder 6, and under the action of the gravity of the material itself, smaller material particles fall into the transmission assembly 3 through the screen hole 16 of the screen cylinder 6, and larger material particles remain in the screen cylinder 6 and continue to roll forward into the extension 7 and slide along the inclined surface of the extension 7 into the receiving box 10.
[0037] Referring to Figure 1As shown, the screening mechanism further comprises a screening moving assembly, which comprises an elastic assembly 8 and a vibrating motor 9, the feeding mechanism and the screening mechanism are both supported by the elastic assembly 8, the vibrating motor 9 is arranged on one side of the screening cylinder 6, and eccentric force is generated by rotation of an eccentric wheel to cause vibration, the vibration of the vibrating motor 9 is transmitted to the screening cylinder 6 to cause the screening cylinder 6 to vibrate, and meanwhile, since the feeding mechanism and the screening mechanism are both supported by the elastic assembly 8 (spring), the vibration of the screening cylinder 6 cannot be excessively absorbed or disturbed by the rack 1. During the vibration of the screening cylinder 6, the movement state of the material in the screening cylinder 6 changes, and the material originally rolling in the screening cylinder 6 will more frequently contact the screen of the screening cylinder 6 under the action of vibration, so that smaller material particles are more easily screened through the screen hole 16, thereby improving the screening efficiency, and the first driving member 4 is a driving motor and is provided with a speed reducer 15.
[0038] Further comprising a rack 1, the transmission assembly 3, the feeding mechanism and the screening mechanism are all arranged on the rack 1, the rack 1 bears the weight of the feeding mechanism, the screening mechanism and the transmission belt 31, so that the transmission belt 31, the screening cylinder 6 and the extension part 7 can be arranged obliquely and the stability of the whole device is maintained.
[0039] Referring to Figure 1 , Figure 4 As shown, the transmission assembly 3 comprises a transmission belt 31 and a second driving member 5 arranged on the rack 1, the transmission belt 31 is sleeved with a driving roller at both ends, the driving rollers are both rotationally connected to the rack 1, at least one of the driving rollers is connected with the output end of the second driving member 5, and the second driving member 5 is a driving motor, since the transmission belt 31 is sleeved on the two driving rollers, when the driving rollers rotate, the transmission belt 31 is driven to circulate by the friction force between the driving rollers and the transmission belt 31, and one end of the transmission belt 31 is arranged below the screening cylinder 6.
[0040] Referring to Figure 5As shown, the transmission assembly 3 is further provided with a limiting assembly 32, which comprises a support frame 321 provided on the rack 1, a first roller 323 rotatably connected to the support frame 14, and a second roller 322 provided on both sides of the first roller 323 and rotatably connected to the support frame 14. The second roller 322 is inclined, and the height of the end of the second roller 322 away from the first roller 323 is greater than that of the first roller 323. The transmission belt 31 covers the first roller 323 and the second roller 322 and is in rolling connection with them, so that the middle of the transmission belt 31 is concave downward, so that the transported crushed materials are concentrated in the middle of the transmission belt 31, avoiding the crushed materials from spilling to both sides during the transportation process. Further, in a vibrating environment, the crushed materials are not easy to leak out due to vibration, but are continuously concentrated in the middle along the inclined transmission belt 31 limited by the second roller 322, improving the stability of the conveying while the concave space also increases the capacity of the transmission belt 31, which can convey more crushed materials at the same time.
[0041] The plurality of elastic assemblies 8 are connected to the rack 1 at one end and connected to the hopper 2, the screen cylinder 6 or the extension 7 at the other end. When the screen cylinder 6 is screening under the action of the vibrating motor 9, the screen cylinder 6 will vibrate. Since one end of the elastic assembly 8 is connected to the rack 1, the vibration of the screen cylinder 6 will cause the elastic assembly 8 to stretch and deform. The elastic assembly 8 provides a larger elastic space for the vibration of the screen cylinder 6 and prevents the vibration of the screen cylinder 6 from being excessively transmitted to the rack 1.
[0042] The shaft 13 is provided with at least two bearings, and the at least two bearings are arranged on both sides of the shaft 13 and fixed to the rack 1. When the first driving member 4 drives the shaft 13 to rotate, the bearings on both sides provide rotational support for the shaft 13. The shaft 13 is fixedly sleeved in the inner ring of the bearing, and the circumferential side is fixedly connected to the rack 1.
[0043] The transmission assembly 3 is inclined, and the inclination angle is consistent with that of the screen cylinder 6 and the extension 7. After the material is screened in the screen cylinder 6, the smaller material falls onto the inclined transmission assembly 3 through the screen cylinder 6. The inclination angle of the transmission assembly 3 satisfies that the crushed materials do not roll downward on the transmission belt 31, such as 5°, 10° or 15°. In some embodiments, the height of one side of the rack 1 is adjustable, so that the transmission belt 31 can be adjusted to different heights.
[0044] Referring to Figure 6 As shown, the screen cylinder 6 and the extension 7 are both annular. The screen cylinder 6 is provided with a plurality of screen holes 16 on the circumferential side. The inner diameter of the extension 7 is not less than that of the screen cylinder 6. Since the inner diameter of the extension 7 is not less than that of the screen cylinder 6, the material can smoothly enter. The inclined arrangement of the extension 7 makes the material slide along the inner wall of the extension 7 under the action of gravity and finally fall into the receiving box 10. The inner wall of the extension 7 is polished and can be provided with a wear-resistant layer.
[0045] Referring to Figures 2-3 As shown in the drawings, the screen cylinder 6 is further provided with a shell 12, the shell 12 is installed on the rack 1, the shell 12 is wrapped on one side of the screen cylinder 6 and does not contact the screen cylinder 6 to avoid affecting rotation, and the screen cylinder 6 is guided at the bottom to prevent shaking out of the conveying belt 31.

[0048] The feeding unit, for small particle materials such as sand with good fluidity, can adopt a conveying belt feeding mode. A hopper is arranged at the starting end of the conveying belt, so that the loader or other feeding equipment can pour sand into the hopper. The inner wall of the hopper is smooth and has a certain inclination angle (such as 60°-75°), so that the sand can smoothly slide onto the conveying belt. The end of the conveying belt extends to above the input port of the stock bin 2, and an adjustable discharging device such as a discharging baffle is arranged at the end. The discharging baffle can be adjusted in angle according to needs to control the landing point and flow of the sand entering the stock bin 2.
