Problems solved by technology

The process of cleaning the stems is time consuming and can damage bud formation at the nodes
Second, the cutting environment is dirty due to the presence of dust from cutting and sap from cut stems (dust and sap can obscure vision sensors and cause slow or imprecise detection of knots)

Embodiment Construction

[0067] figure 1 and 2 The cutting machine (10) of the present invention is schematically shown in . This figure discloses a specific exemplary embodiment of the cutting machine of the present invention for identifying and cutting stem segments of sugarcane.

[0068] The cutting machine of the present invention relates to the cutting of stem segments (pieces) comprising at least one characteristic by controlled and automated means. The cutting machine of the present invention is particularly useful for cutting stem sections of grasses such as sugar cane, in particular Saccharum. Stem segments are characterized, for example, by nodes comprising buds.

[0069] As mentioned above, it has been observed that when a segment comprising a node is treated with certain compounds and / or fertilizers, the segment can be planted to grow new plants. Therefore, it may be desirable to cut the stem into segments comprising only one node in order to improve the efficiency of planting techniqu...

Abstract

The invention generally refers t.o a cutting machine to cut stem segments with desired characteristics. The invention is particularly useful to cut stem segments of graminaceous plants (from the 'Gramineae / Poaceae' family) such as plants of the Saccharum spp, including sugar cane. According to an embodiment of the invention, the cutting machine comprises a sensor (24) to identify at least one characteristic of the stem (40), means (60, 61) to place the stem in a determined position for cutting, depending on the response of said sensor, and means to cut the stem; wherein said sensor to identify at least one characteristic of the stem, said means to cut the stem are interconnected to each other and controlling means (30) in order to cut the stem at a particular position depending on the presence of said identified characteristic; characterized in that the sensor is selected from the group consisting of a pressure transducer sensor, a capactive sensor, an ultrasound sensor, an x-ray sensor, a magnetic sensor, and a microwave sensor.

Description

technical field [0001] The present invention relates generally to a cutting machine, and more particularly to a cutting machine for cutting stem segments having desired characteristics. [0002] The invention is particularly useful for cutting stem segments of grasses (from the family Gramineae / Poaceae) including plants of the genus Saccharum spp, including sugarcane. [0003] The invention also relates to a method for cutting stems of such plants comprising desired characteristics. Background technique [0004] For the purposes of the following specification and appended claims, the current definitions apply: [0005] Stem: The main stem or stalk of the culm part of a grass, ie, the main trunk of the plant, specifically, the main plant stem axis from which buds and shoots develop. [0006] Piece: A segment, part or cut of a stem having one or more nodes. [0007] Node: The part in the stem of a Poaceae plant that forms a bud or bud. [0008] Bud or spore bud: The germ, ...
