[0002] Pulverizers are widely used in many industries, such as pharmaceuticals, food, chemicals, etc. In these industries, it is often necessary to replace different types of cutters according to different production needs.

[0003] However, existing pulverizers often require complicated operation steps when replacing the cutter, which not only reduces work efficiency, but also increases the difficulty of operation and safety risks. Specifically, the traditional pulverizer cutter replacement process usually involves multiple steps, such as loosening the fixing screws, removing the old cutter, installing the new cutter, re-tightening the screws, etc. This process takes a long time and manpower, especially in large or heavy pulverizers, the replacement of the cutter is more difficult and dangerous. In addition, if the operation is improper during the replacement process, it may cause problems such as cutter dislocation, damage or personal injury. For this reason, we propose a pulverizer that is easy to replace the cutter. Utility Model Content

[0011] Preferably, the elastic member is a spring, one end of the spring is mounted on one side of the baffle, and the other end of the spring is mounted on the top surface of the L-shaped baffle.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The crusher is convenient for replacing the cutter. When the cutter needs to be replaced, the baffle is pulled up to disengage the insertion rod from the through hole. At this time, the position of the L-shaped baffle is changed by rotating the rotating plate so that the cross pad is not blocked. Then the cross pad is taken out from the cross slot, and the cross connecting plate is taken out from the cross slot. The work of taking out the crushing blade can be completed, and its disassembly is relatively convenient.

[0014] 2. The crusher is convenient for replacing cutters. The cross connecting plate connected to the crushing blade to be used is placed into the cross slot, and the cross pad is covered on the top surface of the cross connecting plate.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] Please refer to Figure 1-4 As shown, the utility model provides a pulverizer for easy replacement of knives, including a pulverizing cylinder 1, a plurality of supporting legs 2 for carrying the pulverizing cylinder 1 are installed on the bottom surface of the pulverizing cylinder 1, a motor 3 is installed on the bottom surface of the pulverizing cylinder 1, a rotating column 4 is installed on the output end of the motor 3, the rotating column 4 movably penetrates the bottom of the pulverizing cylinder 1, a cross slot 5 is opened on the top surface of the rotating column 4, a cross connecting plate 6 is placed in the cross slot 5, a plurality of pulverizing blades 7 are installed on the outer side of the cross connecting plate 6, and a cross pad 14 is placed on the top surface of the cross connecting plate 6;

[0023] A through hole 10 is formed on the top surface of the rotating column 4 , and a rotatable limiting assembly is disposed on the outer side of the rotating column 4 , and the limiting assembly is used to limit the top of the cross pad 14 .

[0024] Specifically, the cross pad 14 and the cross connecting plate 6 can be limited and fixed by the limiting assembly. After the limiting is cancelled, the cross connecting plate 6 and the crushing blade 7 can be easily replaced.

[0025] Among them: the shape and size of the middle part of the cross connecting plate 6 is appropriately matched with the shape and size of the cross slot 5, the shape and size of the middle part of the cross pad 14 is matched with the shape and size of the cross slot 5, the sum of the thickness of the cross connecting plate 6 and the cross pad 14 is equal to the depth dimension of the cross slot 5, after the cross connecting plate 6 and the cross pad 14 are placed in the cross slot 5, the cross connecting plate 6 and the cross pad 14 cannot move in the horizontal direction, the cross pad 14 has a certain protective effect on the cross connecting plate 6, and at this time the top surface height of the cross pad 14 is level with the top surface height of the rotating column 4.

[0026] The upper end of the L-shaped baffle plate 12 is installed on the upper end of the L-shaped baffle plate 14, and an elastic member is arranged between the baffle plate 12 and the top surface of the L-shaped baffle plate 9. The outer diameter of the plug rod 11 matches the inner diameter of the through hole 10. The elastic member is specifically a spring 13. One end of the spring 13 is installed on one side of the baffle plate 12, and the other end of the spring 13 is installed on the top surface of the L-shaped baffle plate 9. The baffle plate 12 is pulled up to make the plug rod 11 disengage from the through hole 10. At this time, the position of the L-shaped baffle plate 9 can be changed by rotating the rotating plate 8. Rotating the rotating plate 8 drives the L-shaped baffle plate 9 and the plug rod 11 to rotate. When the plug rod 11 faces the through hole 10, the baffle plate 12 and the through hole 10 are driven to move downward under the action of the spring 13, so that the plug rod 11 enters the through hole 10.

[0027] Working principle: The utility model is a crusher that is convenient for replacing the cutter. When the cutter needs to be replaced, the baffle plate 12 is pulled up to make the insertion rod 11 disengage from the perforation 10. At this time, the position of the L-shaped baffle plate 9 is changed by rotating the rotating plate 8 to not block the cross pad 14. Then, the cross pad 14 is taken out from the cross slot 5, and the cross connecting plate 6 is taken out from the cross slot 5, so that the work of taking out the crushing blade 7 can be completed;

[0028] Then, the cross connecting plate 6 connected to the crushing blade 7 to be used is placed into the cross slot 5, and the cross pad 14 is covered on the top surface of the cross connecting plate 6. Then, the rotating plate 8 is rotated to drive the L-shaped baffle 9 to rotate. When an L-shaped baffle 9 drives the insertion rod 11 to move to the through hole 10, the spring 13 pulls the baffle 12 downward, so that the insertion rod 11 is inserted into the through hole 10. At this time, the L-shaped baffle 9 blocks the cross pad 14, and the positions of the L-shaped baffle 9 and the rotating plate 8 are fixed, and the installation of the tool is completed.
