Description

Technical Field

[0001] The present application relates to the technical field of augers, and in particular to a combined bin-discharging auger. Background Art

[0002] Silos are the main form of modern bulk material storage and are widely used in the storage of grain, feed, bulk meal, wood chips, and chemical raw materials. The bulk materials in the silo are generally discharged by the bulk material's self-flow and the forced discharge of the discharge machine buried at the bottom of the silo. The discharge machine is buried deep at the bottom of the bulk material and discharges the bulk materials in the entire silo by the self-rotation of the spiral auger and the revolution along the circumferential direction.

[0048] A plurality of first assembly blades 151 are fixedly connected to the first assembly guard plate 31, and a plurality of second assembly blades 152 are fixedly connected to the second assembly guard plate 32. The first assembly blades 151 correspond to the second assembly blades 152 one by one, and the first assembly blades 151 abut against the second assembly blades 152. The first assembly blades 151 close to the first spiral blade 14 are connected to the first spiral blade 14 through the reinforcement mechanism 5, and the second assembly blades 152 close to the third spiral blade 16 are connected to the first spiral blade 14 through the reinforcement mechanism 5. The other first assembly blades 151 except the first assembly blade 151 abutting against the first spiral blade 14 correspond to the other second assembly blades 152 except the second assembly blade 152 abutting against the third spiral blade 16, and the two ends of the first assembly blade 151 abut against two adjacent second assembly blades 152 respectively. The plurality of first assembly blades 151 and the plurality of second assembly blades 152 are combined to form the second spiral blade 15.

[0049] First, the first assembly guard plate 31 and the second assembly guard plate 32 are both against the middle basic arm, and the axis of the third through hole 322 on the first assembly guard plate 31, the axis of the fourth through hole 121 on the middle arm 12 and the axis of the fifth through hole on the second assembly guard plate 32 are overlapped, and then the end of the reinforcing bolt 341 away from its nut passes through the third through hole 322, the fourth through hole 121 and the fifth through hole in sequence, and the nut of the reinforcing bolt 341 itself is pressed against the second assembly guard plate 32; then the reinforcing nut 342 is threadedly connected with the reinforcing bolt 341 passing through the fifth through hole, and the reinforcing nut 342 is pressed against the first assembly guard plate 31; at this time, the first assembly blade 151 close to the first spiral blade 14 will be pressed against the first spiral blade 14, and the second assembly blade 152 close to the third spiral blade 16 will be pressed against the third spiral blade 16. Finally, the second connecting bolt 33 is passed through the second through hole 321 and is threadedly connected with the second threaded hole 311.

[0050] refer to Figure 2 and Figure 7 In order to quickly make the axis of the third through hole 322 on the second assembly guard plate 32 coincide with the axis of the fourth through hole 121 on the intermediate arm 12, a first groove 122 is provided on the intermediate arm 12, and a positioning mechanism 4 is provided on the intermediate arm 12.

[0051] First, the second assembly guard plate 32 is made to contact the middle arm 12. When the axis of the third through hole 322 does not coincide with the axis of the fourth through hole 121, the positioning bead 41 will be pressed into the first groove 122 by the second assembly guard plate 32, and the spring 42 will be in a compressed state. Then, the second assembly guard plate 32 is rotated. When the axis of the third through hole 322 is aligned with the axis of the fourth through hole 121, the spring 42 restores its elastic deformation. Under the action of the elastic force of the spring 42, the positioning bead 41 will move in the direction close to the second assembly guard plate 32, and the positioning bead 41 will be engaged with the second groove. When the positioning bead 41 is in the second groove, the installer will feel a resistance. Therefore, when the installer feels a resistance when rotating the second assembly guard plate 32, it indicates that the axis of the third through hole 322 on the second assembly guard plate 32 is aligned with the axis of the fourth through hole 121 on the middle arm 12. Then the operator makes the first assembly guard plate 31 contact the second assembly guard plate 32 and the middle arm 12.

[0054] Then, the end of the reinforcing bolt 51 away from its nut is passed through the sixth through hole 531 on the reinforcing plate 53 and the seventh through hole 141 on the first spiral blade 14 in sequence, and then the reinforcing nut 52 is threadedly connected to the reinforcing bolt 51, and the nut of the reinforcing bolt 51 is pressed against the reinforcing plate 53, and the reinforcing nut 52 is pressed against the first spiral blade 14. Then, the end of the reinforcing bolt 51 away from its nut is passed through the sixth through hole 531 on the reinforcing plate 53 and the seventh through hole 141 on the third spiral blade 16 in sequence, and then the reinforcing nut 52 is threadedly connected to the reinforcing bolt 51, and the nut of the reinforcing bolt 51 is pressed against the reinforcing plate 53, and the reinforcing nut 52 is pressed against the third spiral blade 16.
