[0021] In order to clearly illustrate the technical features of the scheme, the scheme will be described below through specific embodiments.

[0022] As Figures 1-5 shown, the rotor module for the feed grinder of the utility model, including rotating shaft 1 and along the circumferential arrangement and with rotating shaft 1 fixedly connected with multiple mounting shafts 4, rotating shaft rotationally connected in the smashing box, the rotating shaft 1 is fixedly connected with multiple side-by-side mounting plates 3, the mounting plate 3 is a circular plate and coaxial with the rotating shaft 1, multiple mounting plates 3 are arranged at equal intervals, the mounting shaft 4 is parallel to the rotating shaft, the mounting shaft 4 passes through the mounting plate 3, thereby realizing the connection with the rotating shaft, the mounting shaft 4 in the embodiment is provided with four.

[0023] One end of the rotating shaft 1 is fixedly connected with a flywheel 5 for increasing the rotational inertia, the other end of the rotating shaft 1 is fixedly connected with a transmission pulley 8 for realizing driving.

[0024] The installation shaft 4 is provided with a plurality of crushing hammers 2, such as Figure 2 As shown, two crushing hammers 2 are provided on each installation shaft 4 between adjacent installation plates 3. An intermediate spacer 7 is provided between adjacent crushing hammers 2, and an edge spacer 6 is provided between the crushing hammers 2 and the installation plate 3. The length of the intermediate spacer 7 is greater than the length of the edge spacer 6, so that the plurality of crushing hammers 2 on each installation shaft 4 are uniformly arranged.

[0025] As shown in Figure 4 , 5 The crushing hammer 2 comprises an intermediate portion 21 and a hammer head portion 22 fixed to both ends of the intermediate portion 21. The intermediate portion 21 is arc-shaped on both sides, and the width of the intermediate portion 21 gradually decreases from the middle to both ends. The length of the intermediate portion 21 is 2-5 times the width, and both sides of the intermediate portion 21 are arc-shaped, so that the crushing hammer 2 can be installed in any direction. Through the arc-shaped structure, the principle of a curved knife is used to cut the material during crushing. In order to improve the cutting effect, the two sides of the intermediate portion 21 are sharpened.

[0026] The hammer head portion 22 is circular and has a diameter greater than the width of the end portion of the intermediate portion 21. The outer circle of the hammer head portion 22 is cylindrical, so that the material is impacted by the cylindrical shape.

[0027] The installation shaft 4 passes through one of the hammer head portions 22. In this embodiment, a circular hole 23 is formed in the center of the hammer head portion 22, so that the entire crushing hammer 2 is symmetrically arranged at both ends in the length direction, facilitating installation and replacement.
