[0026] The upper end opening of the upper shell 2 is the inlet of the outer shell 1 , and the lower end opening of the lower shell 4 is the outlet of the outer shell 1 .

[0027] Two groups of left-right symmetrical first connecting rods 5 are fixedly arranged between the front inner wall and the rear inner wall of the upper shell 2, each group includes two first connecting rods 5, the first connecting rods 5 are arranged horizontally along the front-back direction, and the width between the two first connecting rods 5 on the lower side is smaller than the width between the two first connecting rods 5 on the upper side. A square first material equalizing plate 6 is fixedly arranged on each group of first connecting rods 5, and the angle between the first material equalizing plate 6 and the horizontal plane is 45 degrees; the two first material equalizing plates 6 are arranged symmetrically, and the lower edges of the two first material equalizing plates 6 are spaced apart, the upper edges of the two first material equalizing plates 6 are spaced apart from the left and right inner walls of the upper shell 2, and the front and rear edges of the two first material equalizing plates 6 are spaced apart from the front and rear inner walls of the upper shell 2 respectively.

[0028] A group of second connecting rods 7 are fixedly arranged at the lower ends of the two first connecting rods 5 on the upper side, respectively. The two groups of second connecting rods 7 are symmetrically arranged on the left and right sides, and each group includes four vertical second connecting rods 7. The length of the two second connecting rods 7 on the outer side of each group is shorter than the length of the two second connecting rods 7 on the inner side. A second material equalizing plate 8 is fixedly arranged between the lower ends of the four second connecting rods 7 on the rear side, and a second material equalizing plate 8 is fixedly arranged between the lower ends of the four second connecting rods 7 on the front side. The two second material equalizing plates 8 are symmetrically arranged front and back and are both located at the upper end of the middle shell 3. The angle between the two second material equalizing plates 8 and the horizontal plane is 45 degrees; the lower edges of the two second material equalizing plates 8 maintain a spacing, the upper edges of the two second material equalizing plates 8 maintain a spacing from the front and rear inner walls of the middle shell 3, and the left and right rear edges of the two second material equalizing plates 8 maintain a spacing from the left and right inner walls of the middle shell 3 respectively.

[0029] Two third connecting rods 9 are fixedly arranged between the lower end of the left inner wall and the lower end of the right inner wall of the middle shell 3, and the third connecting rods 9 are arranged horizontally along the left-right direction. Four equidistant fourth connecting rods 10 are fixedly arranged between the front inner wall and the rear inner wall of the middle shell 3, and the fourth connecting rods 10 are arranged horizontally along the front-back direction.

[0030] The working principle of the utility model is:

[0031] The pre-ground material enters the outer shell 1 through the inlet at the upper end. The material first passes through the two first equalizing plates 6, then slides down from the area between the two first equalizing plates 6, then slides between the two second equalizing plates 8, and then slides down from the area between the two second equalizing plates 8. Since the two first equalizing plates 6 are symmetrically arranged left and right, and the two second equalizing plates 8 are symmetrically arranged front and back, the material will pass through the first equalizing plates 6 and the second equalizing plates 8 and then slide down from the center of the middle shell 3 to the upper tip of the third push plate. The material slides evenly from the upper tip of the third push plate to the four sides of the third push plate. The four sides of the third push plate evenly distribute the material around, and finally output it from all around downward through the discharge port of the outer shell 1. This ensures that the material output from the discharge port at the lower end of the outer shell 1 is evenly distributed, and the evenly distributed material then enters the roller press.

[0032] When the material slides down from the four sides of the two first material balancing plates 6, it slides back to the four inner walls of the middle shell 3, and then slides down from the four inner walls of the middle shell 3 to the discharge port at the lower end, and then slides down evenly from the discharge port to be discharged.
