DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0018] As Figures 1 - 3 shown, the present raw material crusher includes a base 1, a lifting platform 12 is arranged on the base 1, the lifting platform 12 is connected to a driving structure capable of moving it up and down, the lifting platform 12 is rotatably connected through a rotating shaft 13 and a connecting arm 16, the connecting arm 16 is connected to the side of the crushing cylinder 9, a power motor 7 is installed on the upper part of the crushing cylinder 9, a crushing knife 10 is installed at the end of the output shaft of the power motor 7, and the crushing knife 10 is located inside the crushing cylinder 9. A hopper 8 is also connected to the upper part of the crushing cylinder 9, a barrier net 11 is installed at the lower part of the crushing cylinder 9, a support block 21 cooperating with the connecting arm 16 is also installed on the lifting platform 12, a bolt 14 is installed on the support block 21, and a locking block 15 cooperating with the bolt of the bolt 14 is fixed in the middle of the connecting arm 16.

[0019] A cleaning port is also arranged on the side of the crushing cylinder 9, and the cleaning port is close to the connecting arm 16. A closing plate 6 is detachably installed at the cleaning port through two locking screws 17.

[0020] The closing plate 6 is provided with a handle 18.

[0021] The driving structure includes a vertical plate 20, a guide rail 3, a sliding table 4 and a cylinder 5. The vertical plate 20 is fixed on the base 1. The guide rail 3 is vertically installed on the vertical plate 20. The sliding table 4 is slidably connected to the guide rail 3. The cylinder 5 is installed on the vertical plate 20. The end of the piston rod of the cylinder 5 is connected to the sliding table 4. The lifting table 12 is connected to the sliding table 4. With this structure, the cylinder 5 drives the sliding table 4 to move up and down along the guide rail 3, and the sliding table 4 drives the lifting table 12 to move up and down, so that the lifting table 12 can drive the crushing cylinder 9 to move up and down.

[0022] An adjustable limit post 19 that cooperates with the sliding table 4 is also installed on the vertical plate 20.

[0023] An electric control box 2 is also installed on the base 1. The power motor 7 and the cylinder 5 are both electrically connected to the electric control box 2 through wires. This is an existing structure and its circuit etc. do not need to be redesigned.
