[0013] In order to better understand and implement the present invention, the present invention is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The research and development team behind this utility model conducted in-depth research into the problem of existing cam rotor pumps being prone to clogging in fluids containing a high concentration of impurities. This analysis revealed that clogging in cam rotor pumps is often caused by large impurities that are difficult to pass through the rotor, instead becoming entangled in it, causing continuous wear and even causing it to stop rotating. This situation significantly shortens the rotor's service life. Therefore, to address this issue, the utility model has designed a chopping device for cam rotor pumps that prevents clogging. By adding this device to existing cam rotor pumps, the chopped device solves the problem.

[0018] Please refer to Figure 1-3 The shredding device includes a first sealing baffle 1, a fixed cutting blade holder 2, a rotating cutting blade 3, and a second sealing baffle 4, which are connected in sequence. The fixed cutting blade holder 2 is provided with seven triangular ribs, two of which have 50-degree angles. The edges are polished to form a fixed cutting blade. The fixed cutting blade holder 2 is also provided with two mounting holes that match the motor shaft. The fixed cutting blade holder 2 is mounted on the motor shaft through the two mounting holes. The rotating cutting blade 3 is provided with four ribs. The edges of the ribs are triangular, two of which have 50-degree angles. The edges of the ribs are polished to form a rotating cutting blade. The rotating cutting blade 3 has a central mounting hole that matches the motor shaft.

[0019] Preferably, the chopping device described in the present invention is more suitable for a pump body with an ellipsoidal interior, and the water inlet and outlet of the pump body are elliptical.

[0020] When in use, the shredding device of the present invention sequentially installs the first sealing baffle 1, the fixed cutting blade holder 2, the rotating cutting blade 3, and the second sealing baffle 4 onto the rotating shaft of the cam rotor pump and places them between the two rotors of the cam rotor pump. The device is easy to install and is applicable to various types of cam rotor pumps. It only needs to adjust the sizes of the above parts to be installed in cam rotor pumps of different types, and is very convenient to use.

[0021] The shredder mechanism of the present invention operates as follows: When the cam rotor pump is in operation, the pumped granular objects or debris are guided through the filter element into the shredder mechanism and land on the fixed cutting blade holder 2, which is fixed to the pump body. Driven by the motor shaft, the rotating cutter 3 cuts the granular objects or debris against the fixed cutting blade holder 2, which is then transported out of the pump body via ribs. The four ribs on the rotating cutter 3 perform four cutting and shredding actions with the fixed cutting blade holder 2 during one revolution, thereby improving cutting and shredding efficiency and achieving finer shredding of debris. This, in turn, reduces blockages, avoids failures, extends the rotor's service life, and increases market competitiveness.

[0022] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
