Description

Technical Field

[0001] The utility model relates to the technical field of specimen making equipment, in particular to a herbarium specimen making device. Background Art

[0002] Plant specimens are a way of collecting, processing and preserving plant samples for a long time. They are important tools for teaching demonstrations and scientific research. According to the preservation form, there are mainly two forms: herbarium specimens and immersion specimens. Herbarium plant specimens are the most common form of plant specimens. Herbarium plant specimens are fresh plant materials pressed with absorbent paper, dried and then bound on a paper base.

[0003] For example, the patent with announcement number CN217136621U discloses a plant wax leaf specimen making tool, which includes two groups of pressed wooden board assemblies and a group of three-point bracket assemblies. The two groups of pressed wooden board assemblies are arranged relative to each other and tied together with fiber ropes. The two groups are used to press the plant wax leaf specimens. The pressed wooden board assemblies each include two wooden sticks and seven wooden strips. The wooden sticks are arranged in parallel. The wooden strips are evenly arranged and fixedly connected to one side of the wooden sticks. Both ends of the other side of the wooden sticks are provided with rope grooves, and the rope grooves are the positions for tying the fiber ropes. The above-mentioned plant wax leaf specimen making tool has shortcomings. Although the device can be used to make specimens, it has limitations. In particular, the needles of coniferous plants fall off after drying. The traditional making method is difficult to succeed and cannot be preserved for a long time. In addition, the setting is easily deformed and damaged. The manual bundling, pressing and drying process is inefficient and requires high experience.

[0004] Therefore, in order to solve this problem, we proposed a herbarium specimen making device. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for making herbaceous plant specimens, including a base, a side wall of the base is provided with a first mounting groove, two mounting columns are fixedly connected to the upper end of the base, and a number of placement plates are evenly fixedly connected to the side walls of the mounting columns, a stepper motor is fixedly connected to the bottom wall in the first mounting groove, a threaded rod is fixedly connected to the output end of the stepper motor, the end of the threaded rod away from the stepper motor passes through the upper surface of the base, and the two mounting columns are respectively located on both sides of the threaded rod, and a number of pressing plates are evenly threadedly connected to the side walls of the threaded rod, and the pressing plates are respectively located directly above the base and the placement plates, a second mounting groove is provided on the upper end of the base and the placement plate, a number of springs are evenly fixedly connected to the bottom wall in the second mounting groove, and a limit frame is fixedly connected to the upper end of the spring, and the side wall of the limit frame farthest from the spring end is slidably connected to the inner wall of the second mounting groove.

[0007] Preferably, the upper end of the mounting column is fixedly connected to a limiting plate.

[0008] Preferably, the stepper motor is electrically connected to an external controller.

[0009] Preferably, the second mounting groove and the limiting frame are both T-shaped.

[0010] Preferably, a protective plate is fixedly connected to the inner wall at the end of the second mounting groove.

[0011] Preferably, the pressing plate is slidably connected to the side wall of the mounting column.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, a threaded rod is used to simultaneously drive a plurality of pressing plates to perform preliminary pressing on a plurality of groups of specimens at the same time, so the production efficiency is high. Secondly, self-spraying glue is sprayed on the back of the specimens that have been preliminarily pressed, and the specimens are positioned and fixed on the prepared paper base. The absorbent paper is replaced every day so that the moisture of the plant specimens is slowly dried, thereby avoiding deformation or damage of the specimens due to rapid water loss, ensuring the drying quality and morphological stability of the specimens, avoiding the shedding of leaves of coniferous plants after drying, and solving the problem that coniferous plant specimens cannot be preserved for a long time.
