Leaf mashing apparatus in chloroplast experiment

Abstract

The invention discloses a leaf mashing apparatus in a chloroplast experiment. A first rectangular through hole is horizontally formed in the lower end of the front surface of a box body, a leaf placement assembly is inserted inside the first rectangular through hole, a stepper motor is fixedly assembled on the middle part of the upper end of the box body, an output rotating shaft of the stepper motor penetrates through the upper wall of the box body to be fixedly provided with a stud, the outer side of the stud is connected with a nut in a threading manner, the left side and the right side ofthe nut are respectively fixedly provided with a first ear plate, the rear surfaces of the two first ear plates are respectively hinged with a pressing rod, the lower ends of the two pressing rods arefixedly provided with a squeezing assembly, the outer side of the squeezing assembly is provided with a guiding assembly, a switch is arranged on the box body, and the switch is electrically connected with the stepper motor. The stepper motor is used for providing power, the squeezing assembly is controlled to move up and down, the squeezing assembly squeezes and mashes leaves placed on the leafplacement assembly, and the mashing of the leaves is mechanically controlled, so that time and labor are saved, and more uniformity in mashing the leaves can be realized.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a leaf crushing device in chloroplast experiments. Background technique [0002] Chloroplasts are organelles in plant cells that are surrounded by double membranes and contain chlorophyll for photosynthesis. [0003] When it is necessary to conduct experiments on the chloroplasts of plants, it is necessary to extract chloroplasts from plant leaves. At this time, it is necessary to mash the plant leaves to facilitate further extraction of chloroplasts. Now most of the experiments are done by manually mashing plant leaves, which is troublesome to operate. The mashing effect of each blade is quite different. When more mashing leaves are needed, manual mashing of leaves is laborious and laborious, and the mashing of leaves by existing machinery is not uniform enough. In order to solve the above problems, we propose a A leaf crushing device in a chloroplast experiment....
