detailed description

In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

As shown in Figures 1, 2 and 3, a stepping feeder includes a power system, a transmission mechanism and a body 8, the transmission mechanism includes a transport frame 7 and a connecting shaft 3, and the connecting shaft 3 is rotatably connected to the On the machine body 8, the connecting shaft 3 is fixedly connected with the conveying frame 7, and the connecting shaft 3 is connected with the output shaft of the power system through transmission. The rotation of the connecting shaft 3 drives the conveying frame 7 to reciprocate, and any point on the conveying frame 7 The trajectory of motion is a closed curve.

Preferably, as shown in Fig. 1 and Fig. 2, the surface of the conveying frame 7 for conveying materials is provided with material troughs 10 at equal intervals, and the material chute 10 and the material trough 10 are provided with materials for pushing the material 9 to move forward. Convex teeth 11.

Preferably, as shown in FIG. 1 , there are two conveying racks 7 arranged symmetrically on both sides of the machine body 8, so as to increase the stability of feeding.

Preferably, as shown in Fig. 1 and Fig. 3, in order to make the conveying racks 7 on the left and right sides move synchronously, bearing holes are provided on both sides of the body 8, and bearings 10 are installed in the bearing holes, and the connecting shaft 3 runs through The body 8 is also installed on the bearing 10; the front end and the rear end of the body 8 are equipped with connecting shafts 3 through the bearings 10, and the connecting shafts 3 are driven by the conveyor belt 6.
