Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of crushing devices, in particular, relates to an energy-saving type block-shaped medicine pulverizer for chemical laboratories and a use method. BACKGROUND

[0002] In the process of chemical experiments, many block-shaped medicines are often encountered. Direct use of block-shaped medicines often results in slow reaction rate and low efficiency due to small contact area with reactants. Therefore, block-shaped medicine bottles often need to be broken and ground to increase the contact area with reactants, so that the reaction is more rapid and sufficient. However, the conventional crushing method is to manually hammer the medicine bottles to break them and then grind them, which is very time-consuming and low in efficiency. The existing patent No. CN214021013U discloses a block-shaped medicine crushing device for biological pharmacy, which comprises a fixed base, a crushing shell fixedly connected to the top of the fixed base, a feed hopper fixedly connected to the top of the crushing shell, a baffle fixedly connected to the inner side wall of the crushing shell, a motor shell fixedly connected to one side of the crushing shell, a connecting rod fixedly connected to the inner wall of the motor shell, and a motor fixedly connected to one end of the connecting rod. The block-shaped medicine crushing device for biological pharmacy has good crushing effect, solves the problem of poor crushing effect of general block-shaped medicine crushing devices for biological pharmacy, and meets the use requirements of people, so that people can use it more conveniently, improve work efficiency, and bring convenience to people's work. The above device can crush medicines, but the crushing method is single. When crushing medicines with slightly hard texture, the motor needs to continuously output large force, which directly leads to frequent peak output power state of the motor. Long-term operation under such high load working conditions greatly increases the stress of internal components of the motor, not only significantly increases the power consumption of the motor, causing energy waste, but also accelerates the insulation aging and bearing wear of the motor, thereby greatly increasing the failure rate of the motor, affecting the stability and reliability of the overall operation of the equipment. Therefore, the present application is proposed. SUMMARY
