As shown in fig. 1, the feeding screw of the present embodiment can be installed in a feeding channel of a spiral feeding device to realize a propelling action on a feeding process of a material. Specifically, defeated material screw rod of this embodiment includes dabber 1, blade 2 and keeps off the material body 4. At least two groups of blades 2 are arranged at one end of the mandrel 1, each group of blades 2 spirally spirals on the outer wall of the mandrel 1 along the axial direction of the mandrel 1, and the mandrel 1 can drive all the blades 2 to synchronously rotate when rotating, so that materials are pushed to feed along the spiral direction of each group of blades 2. Preferably, each set of blades 2 is integrally connected with the outer wall of the mandrel 1, so as to avoid material feeding time lag between the blades 2 and the mandrel 1. The spiral directions of the blades 2 are preferably consistent, so that the spindle 1 can drive the materials to continuously feed in the same direction when driving the blades 2 to synchronously rotate. The one end of keeping away from each group blade 2 on preferred dabber 1 is equipped with the step shaft, is equipped with the connection keyway on the step shaft to dabber 1 is connected with the power unit of defeated material equipment of spiral.

In the embodiment, gaps 3 are reserved between adjacent blades 2, at least one material blocking body 4 is fixed in each gap 3, and the material blocking bodies 4 are used for stirring materials in feeding. This stirring effect can make the material of feeding difficult excessively extruded to loose the material of piling up together when feeding, the inside gas outgoing of help material makes the transportation process of material more smooth and easy. Furthermore, the material conveying screw can prevent materials from being blocked in the feeding process to cause material accumulation in the material conveying channel, and the material conveying efficiency and the safety of the spiral material conveying equipment are improved.

It will be appreciated that the length and thickness of each set of blades 2 described in the present embodiment may be the same or different, and the width of the gap 3 between adjacent blades 2 may be varied as desired.

In this embodiment, each material blocking body 4 is fixed on the mandrel 1 in each gap 3, and the axis of the material blocking body 4 is perpendicular to the axis of the mandrel 1, so that the material blocking body can be fully inserted into a material pile in feeding from the radial direction during stirring, and the effect of radially stirring the dispersed and loose materials is achieved.

In this embodiment, a blocking body 4 is fixed on the mandrel 1 in the same gap 3, and when the blocking body 4 rotates along with the mandrel 1, a stirring section is formed outside the mandrel 1 to stir the fed material.
