[0002] In the process of lithium battery production, it is usually necessary to use a spiral silo plowshare breaking device to break up the large aggregates of wet materials squeezed out. As a key component in the spiral silo plowshare breaking device, the plowshare can be driven to rotate by a motor to break up the large aggregates of wet materials squeezed out. In the prior art, the plowshare generally includes a plowshare head and a plowshare frame. In order to meet the material hardness requirements for material breaking up, the plowshare head and the plowshare frame are both made of titanium alloy. In addition, during the installation of the plowshare, it is necessary to first fix the plowshare head on the plowshare frame by welding, and then fix the plowshare frame with the plowshare head on the motor shaft by a clamp. Since titanium alloy materials have defects such as low welding toughness, and the plowshare has to withstand a large torque during the process of rotating and breaking up the material, the weld between the plowshare head and the plowshare frame is prone to tearing, thereby affecting normal production.

[0003] Therefore, how to improve the connection reliability between the coulter head and the coulter frame has become a difficult problem to be solved urgently by those skilled in the art. Utility Model Content

[0031] It should be noted that specific details are described in the following description to facilitate understanding of the present invention. However, the present invention can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] In the process of lithium battery production, it is usually necessary to use a spiral silo plowshare breaking device to break up the large aggregates of wet materials squeezed out by the filter press. As a key component in the spiral silo plowshare breaking device, the plowshare can be driven to rotate by a motor to break up the large aggregates of wet materials squeezed out. In the prior art, the plowshare generally includes a plowshare head and a plowshare frame. In order to meet the material hardness requirements for material breaking up, the plowshare head and the plowshare frame are both made of titanium alloy. In addition, during the installation of the plowshare, it is necessary to first fix the plowshare head on the plowshare frame by welding, and then fix the plowshare frame with the plowshare head on the motor shaft by a clamp. Since titanium alloy materials have defects such as low welding toughness, and the plowshare has to withstand a large torque during the process of rotating to break up the material, the weld between the plowshare head and the plowshare frame is prone to tearing, thereby affecting normal production.
