[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] Combination Figure 1-3 As shown, a new feeding mechanism for high-moisture raw materials includes:

[0024] The material storage box 1 has a feed hopper 11 on the top, which is mainly used to assist in the auxiliary transportation of wet materials and temporarily store them;

[0025] The screening box 2 is arranged at the bottom of the storage box 1 and is connected with the bottom discharge port of the storage box 1 to screen the wet material inside the storage box 1. The end of the screening box 2 is also provided with a discharge port 21 to discharge debris.

[0026] The breaking component 3 is arranged inside the storage box 1 to initially disperse the agglomerated materials and speed up the subsequent screening efficiency;

[0027] The dynamic screening component 4 is arranged inside the screening box 2 and is the main part of the screening structure, and can also play a certain role in breaking up;

[0028] The material conveyor 5 is a belt conveyor device used to transport the screened material to the next process.

[0029] Specifically; in the present embodiment, the breaking component 3 is composed of three shafts, namely a first stirring shaft 31, a second stirring shaft 32 and a third stirring shaft 33, wherein the second stirring shaft 32 and the third stirring shaft 33 are located in the lower half of the storage box 1 and are arranged horizontally at intervals, and the first stirring shaft 31 is arranged above the center of the second stirring shaft 32 and the third stirring shaft 33, so when the material enters the box through the feed hopper 11, it will first contact the first stirring shaft 31, and then contact the second stirring shaft 32 and the third stirring shaft 33.

[0030] The stirring structure arranged on the first stirring shaft 31 is a stirring rod, that is, multiple stirring rods are used to initially break up the materials entering the box body, wherein larger debris will be quickly moved to both sides, and clumped materials will be broken up and fall into the position between the second stirring shaft 32 and the third stirring shaft 33.

[0031] The stirring structure adopted by the second stirring shaft 32 and the third stirring shaft 33 is a triangular stirring blade, and a plurality of stirring blades are provided. The stirring blades on the second stirring shaft 32 and the third stirring shaft 33 are staggered and rotate in the same direction. When the material approaches the second stirring shaft 32 and the third stirring shaft 33, it will be squeezed by the stirring blades until it just fits the gap size between the second stirring shaft 32 and the third stirring shaft 33, so that it can be discharged smoothly downward, and some impurities with larger structures will be pushed to both sides by the stirring blades, and also discharged into the screening box 2 along the discharge port at the bottom.

[0032] After the above preliminary breaking up work, the material clumps have been dispersed or become smaller material clumps, so the volume difference between the impurities becomes more obvious, so that these impurities can be separated more quickly.

[0033] An installation space is also separated inside the storage box 1 by a partition, and a drive motor 34 is arranged in the installation space. One end of the first stirring shaft 31, the second stirring shaft 32 and the third stirring shaft 33 extend into the installation space and are provided with gears 35 at the ends. The three gears 35 are arranged in a triangle shape and rotate in the same direction through a chain, and the drive motor 34 is connected to one of the stirring shafts.

[0034] The dynamic screening component 4 includes two fixed plates 41 arranged at intervals. The bottom center of the bottom surface of the screening box 2 is partially hollowed out, and the two fixed plates 41 are fixedly installed on the two sides of the hollowed out part. A plurality of through holes are provided on the side walls of the fixed plates 41. A screening shaft 42 is provided inside each through hole. A dividing piece is provided on the outer wall of the screening shaft 42. The dividing pieces on every two adjacent screening shafts 42 are arranged in an interlaced manner, and all the screening shafts 42 rotate toward the impurity discharge port 21.

[0035] Both ends of these screening shafts 42 are movably connected to the fixing plates 41 respectively, and one end thereof extends outward to the outer wall of the screening box 2, and a servo motor 44 is arranged on the outer wall of the screening box 2 to drive the screening shafts 42 to rotate.

[0036] The above driving method can be set up through a belt transmission structure, that is, all the screening shafts 42 are connected by a belt, or a gear 35 drive structure, and a chain plate drive structure, or the servo motors 44 are set to a corresponding number and controlled in parallel. In this embodiment, multiple servo motors 44 are arranged accordingly and fixed to the outer wall of the screening box 2 using a motor base.

[0037] A metal filter screen 43 is arranged between the bottom surfaces of the two fixing plates 41 , and a vibration motor is provided at the center of the bottom surface of the metal filter screen 43 .

[0038] In addition, the bottom surface of the entire screening box 2 is tilted downward as a whole, so the entire dynamic screening assembly 4 is also tilted downward as a whole, and its debris discharge port 21 is arranged on the downward end side wall of the screening box 2, so the vibration motor can quickly transport the debris adhered to the surface of the metal filter mesh 43 to the debris discharge port 21 during the vibration process.

[0039] An auger is also provided at the end of the debris discharge port 21 , which is arranged longitudinally and has one end extending to the outside of the screening box 2 and connected to a debris discharge motor 22 . The debris discharge motor 22 is also fixedly connected to the side wall of the screening box 2 using a motor seat.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
