Continuous extrusion type plant specimen dehydration machine

Abstract

The invention discloses a continuous extrusion type plant specimen dehydration machine. The dehydration machine comprises a box body, a partition plate is fixed on the box body, a support rod is mounted on the partition plate, the support rod and an upper pressing push rod are connected through a tension spring, the upper pressing push rod passes through the partition plate and is connected to anupper pressing plate, a lower pressing plate is installed on a frame plate and is connected to the frame plate through a buffer spring, a servo motor is arranged in the middle of the box body, an output shaft of the servo motor is sleeved by a dividing cam, the dividing cam is provided with a dividing chute, an output rod is provided with a spherical sliding body, the spherical sliding body is located in the dividing chute and is connected to the dividing chute, the partition plate is provided with an opening, and the output rod is connected to the upper pressing push rod. The two springs provide self-applied pressure and the dividing cam drives the upper pressing push rod to push back and forth so that plant fast dehydration is realized and the pressing effect is good. The dehydration machine does not easily cause plant specimen damage and pressing plate deformation.

Description

technical field [0001] The invention belongs to the field of specimen preparation, in particular to the specimen preparation of plant leaves, in particular to a continuous extrusion type plant specimen dehydration preparation machine. Background technique [0002] Making plant specimens is one of the powerful means to solve the problem of botanical teaching aids. The use of plant specimens in classroom teaching preserves the shape and color of plants, which not only helps students deepen their knowledge and understanding, but also breaks through regional and seasonal restrictions. At the same time, plant specimens preserve the shape and color of plants for future use. Re-observation and research, a few plant specimens also have the value of collection. [0003] For the existing pressure-dried specimen preparation steps, fresh and tender green leaves are picked, placed in the cavity of the specimen preparation machine, and dehydrated by pressing. The pressing process adopts ...

AI Technical Summary

Problems solved by technology

[0003] For the existing pressure-dried specimen preparation steps, fresh and tender green leaves are picked, placed in the cavity of the specimen preparation machine, and dehydrated by pressing. The pressing process adopts directional pressing to keep the pressure constant and carry out continuous pressing. During this period, absorbent paper needs to be placed to absorb the water in the green leaves, but the dehydration speed is slow with this pressing device, and it is inconvenient to replace the absorbent paper regularly, which greatly affects the production efficiency of plant specimens
