[0020] Please refer to Figure 1-Figure 4 A raw material crushing and screening device for processing jujube powder feed comprises a jujube powder screening box 1: the upper surface of the jujube powder screening box 1 is fixedly connected with a connecting cover 2, the upper surface of the connecting cover 2 is fixedly connected with a jujube crushing box 3, the inner wall of the jujube crushing box 3 is fixedly inlaid with a bearing ring 6, the inner ring of the bearing ring 6 is fixedly connected with a jujube crushing roller 4, the bottom surface of the jujube crushing box 3 is fixedly installed with a blocking filter screen plate 5, the interior of the jujube powder screening box 1 is provided with a sieve plate 9, the inner side wall of the jujube powder screening box 1 is fixedly connected with two motor support plates 11, and the upper surfaces of the two motor support plates 11 are fixedly installed with vibration motors 12. The vibration motor 12 is a set of adjustable eccentric blocks installed at both ends of the rotor shaft, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is used to obtain the exciting force. The vibration of the vibrating body is generated by two sets of exciting systems, and its vibration form is called compound vibration. Generally, there are two types: dual-frequency composite type and dual-width composite type. The output ends of the two vibration motors 12 are fixedly connected to the bottom surface of the sieve plate 9. The bottom surface of the sieve plate 9 is fixedly inlaid with a jujube powder screen 10. The upper surface of the jujube crushing box 3 is provided with a jujube injection port 8. The setting of the jujube injection port 8 facilitates the injection of jujubes. The connecting cover 2 can make the crushed jujube powder slide into the inside of the jujube powder screening box 1, which is convenient for screening.

[0021] During the specific implementation process, two groups of slide grooves 19 are provided on the inner wall of the jujube powder screening box 1, and the inner walls of the two groups of slide grooves 19 are slidably connected with sliding blocks 18.
