In the invention, the main material pusher 4 is divided into three-section structures to form three-section pushing radians, the tail-section pushing structure 42 with the smallest width is used for bearing the pushing assembly 6 and forming front-end acting force with concentrated middle acting force, then the middle-section pushing structure 41 with the medium width applies second acting force which mainly acts on the first-section pushing structure to form a second layer, and finally the first-section pushing structure 40 with the largest width applies third acting force and uniformly pushes away cotton spins along the peripheral inner walls of the storage box. In the invention, three-stage level acting force is adopted to form ordered pushing, thus avoiding the defects of more cotton spinning amount and high pushing difficulty of the pusher at the beginning and prolonging the service life of the pusher.
As further preferred, in this embodiment of the present invention, as shown in fig. 6, the top end of the end pushing structure 42 is a concave "U" shaped groove, and the width of the "U" shaped groove is greater than or equal to the width of the pushing assembly 6. In the invention, the top end of the tail-section pushing structure 42 is a concave U-shaped groove, which is beneficial to forming a movable interval between the pushing assembly 6 and the tail-section pushing structure 42, thereby being beneficial to the movement of the pushing assembly 6.

As a further preferred, the certain time period of the operation between the auxiliary pusher bar 5 and the main pusher bar 3 is in the range of 3-5s, if the interval time is too long, the operation time interval between the main pusher 4 and the auxiliary pusher is too long, and cotton spins which are not pushed or missed after the operation of the front auxiliary pusher fall on the bottom of the storage box or fall in a movement gap between the auxiliary pusher and the main pusher 4, so that the pusher is jammed and blocked or the blanking is not clean, and a new problem is caused. Similarly, if the pushing assembly 6 connected to the top end of the auxiliary pushing rod 5 is arranged, the pushing assembly 6 is positioned at the top end of the main pusher 4, and a certain middle acting force and a certain side acting force can be equal; when the pushing assembly 6 connected to the top end of the auxiliary pushing rod 5 is arranged, the pushing assembly 6 protrudes out of the top end of the main pusher 4, namely, the pushing assembly 6 is exposed out of the main pusher 4, so that under the action force of the middle part, the main force cotton spinning moves in advance to feed and drives the peripheral wall cotton spinning under the action force of the side edge to move to feed, the feeding is quicker, and the action force effect is obvious.

Specifically, as shown in fig. 2 and 3, in this embodiment of the present invention, two secondary pushing rods 5 are provided and symmetrically provided at one end of the pushing assembly 6, so as to realize the movement of the pushing assembly 6 in the length direction. Of course, when the main pusher 4 and the auxiliary pusher move synchronously, as shown in fig. 2, the number of the main pusher rods 3 is set to be 2, and the main pusher rods are respectively and symmetrically arranged at one end of the main pusher 4; then, at the same time, the number of the auxiliary pushing rods 5 is also two, and the two auxiliary pushing rods are respectively and symmetrically arranged at one end of the auxiliary pushing rod 5; or the number of the main material pushing rods is set to be 1, and the main material pushing rods are arranged at one end of the main material pusher 4; then, at the same time, the number of the auxiliary pushing rods 5 can also be set to be one or two, and the auxiliary pushing rods are respectively arranged at one end of the auxiliary pushing rod 5; when the main pusher 4 and the auxiliary pusher do not synchronously move, the main pushing rods 3 of the main pusher 4 can be one or two, and the auxiliary pushing rods 5 of the auxiliary pusher can also be one or two.
