Boilogical teaching experiment display crushing and grinding integrated mortar capable of being rapidly disassembled and assembled

Abstract

The invention discloses a biological teaching experiment display crushing and grinding integrated mortar capable of being rapidly disassembled and assembled. The mortar comprises a mortar shell, a switch cover and a feeding hole, wherein an opening at a top end of the mortar shell is covered with a switch cover, crushing rods which are distributed in an inclined manner are mounted on an auxiliarytransmission rod, the two are in welded connection, a connecting rod is arranged in the mortar shell, the connecting rod is located below a supporting plate, a top end of the connecting rod is rotationally connected with a main transmission rod, a bottom end of the connecting rod is connected with a second frame, a second connecting shaft is installed on the second frame, the connecting rod and the second frame are rotationally connected, and a second grinding roller is fixedly connected with the second connecting shaft. The mortar has the advantages that in the same device, the grinding mechanism and a crushing mechanism are driven by the power of a motor to operate synchronously, the grinding and crushing dual-operation effect on objects is better, moreover, the whole device can be conveniently disassembled and assembled, and the mortar use is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of biology teaching experiments, in particular to a rapidly detachable mortar for biology teaching experiments displaying crushing and grinding. Background technique [0002] Biology teaching can help students to study biology content systematically. In the actual teaching process, in order to show students that different organisms are different in different forms, it is often necessary to use a grinding bowl to grind or pulverize substances. Now Some grinding bowls are generally driven by a motor to grind the internal stirring and crushing structure, and the objects are crushed. Although they can meet the use requirements to a certain extent, the existing grinding bowls have the following problems in actual use: [0003] 1. The function is relatively single. The grinding bowl generally only has a single grinding or crushing function, and the manual operation is too laborious, and it is too wasteful to use t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of biological teaching experiment display crushing and grinding integrated mortar that can be disassembled quickly, so as to solve the problem that the function is relatively single in the above-mentioned background technology. The grinding bowl generally only has a single grinding or crushing function, and manual The operation method is too laborious, and it is too wasteful to use the motor drive structure to drive a single function, which makes the input cost of the device higher; the feeding or discharging of the device itself is realized through the feeding and discharging structure on the surface of the device, and the device itself The structure is not easy to disassemble, and it is too troublesome to clean up or replace accessories later, and the operation is very inconvenient.
