Stem cutting machine

Abstract

The invention discloses a stem cutting machine. By arrangement of a material storage box, a user can randomly store stems to be cut into the box, and the stems are tidily sequenced through a conveying belt group, and then are output into a feeding mechanism in sequence; the feeding mechanism conveys one single stem to a locating and conveying mechanism; the locating and conveying mechanism can accurately locate the single stem and output the single stem to a clamping mechanism and a cutting mechanism; after the clamping mechanism clamps the single stem, the cutting mechanism cuts the single stem; a matched universal test machine is used for recording data such as a force value and deformation in a stroke process of the cutting mechanism; after the test data of cutting are recorded, the tested stem can be continuously conveyed forwards by the locating and conveying mechanism and then fall off; furthermore, the previous mechanisms repeatedly convey the rest stems for uninterrupted stem test, so that the test efficiency is greatly improved, and no worker needs to change the stems at each time; therefore, labor resources are liberated, batch stem cutting data can be easily acquired, the data precision is improved, and an accurate and systematic test result can be obtained favorably.

Description

technical field [0001] The invention relates to the field of plant stem mechanics tests, in particular to a stem cutting machine. Background technique [0002] Ramie is a traditional characteristic economic crop in my country and has high utilization value. my country's ramie output accounts for more than 90% of the world's total output, and it is the largest main producer of ramie in the world. At present, ramie is mainly harvested manually, which is extremely labor-intensive. Due to the restriction of harvesting methods, the planting area and output of ramie in my country have decreased sharply, and the industry is facing the risk of disappearing. Therefore, the premise of developing modern ramie harvesting technology is to develop a ramie harvester to realize the mechanized harvesting of ramie. The optimization of the parameters of the cutting tool directly affects the power distribution of the cutting parts and the design size of the transmission mechanism to ensure re...

Problems solved by technology

[0003] In the prior art, in order to study the impact of the double-moving knife cutter on field use, an indoor test device is used to solve the problem of the experimental research; the indoor cutting machine places a ramie stalk once and cuts it by the double-moving knife. According to the maximum cutting driving force and cutting power consumption of ramie stalks under different cutting blades and cutting forms, but the existing cutting machine needs to manually assemble and disassemble the workpiece to replace the ramie stalk when testing each ramie stalk. When testing different cutting blades, it is necessary to manually change the cutting tool, which is inefficient during the test
