Abstract
A helical conveyer using a dual-pitch helix comprises a rack, a barrel, a feeding port, a discharging port, a screw rod and a driving device, wherein the screw rod is connected with the driving device, the helix of the screw rod is formed by the smooth connection of two sections of helixes with different helical pitches and same rotating direction along the axis direction of the screw rod, and the helical pitch of the helix at one side of the discharging port is larger than the helical pitch of the helix at one side of the feeding port. Besides using two sections of helixes with a fixed helical pitch, the dual-pitch helix can also use a helix with varying helical pitches, and the helical pitch of at least one section of helix is gradually increased grade by grade or continuously increased from one side of the feeding port to one side of the discharging port. The helical conveyer using a dual-pitch helix can constitute a single-screw-rod conveyor or a dual-screw-rod conveyor. The driving device is provided with a rotating speed adjustment mechanism. By using the helical conveyer with dual-pitch helix, materials with large conveying viscosity and easy caking can be smoothly conveyed, without the occurrence of the blocking problem of the helical conveyer, thereby being convenient to improve the conveying level of materials and increasing the conveying characteristic functions of materials.
