DETAILED DESCRIPTION OF THE EXECUTION EXAMPLES

[0029] Fig. 1 bis 5 Figure 1 shows a forestry equipment system 10 according to the invention. The forestry equipment system 10 comprises a forestry device 20. The forestry device 20 has a movement device 30, a processing tool 40, and a measuring device 50. The movement device 30 is designed for independently moving the forestry device 20 along at least one section 92 of a standing tree trunk 91, in particular a tree 90. The processing tool 40 is designed for processing the section 92. The measuring device 50 is designed for measuring geometric parameters GK of the section 92. The forestry equipment system 10 is designed to output at least one piece of information Info based on the measured geometric parameters GK. In alternative embodiments, the forestry equipment system can additionally or alternatively be designed to transmit the at least one piece of information.

[0030] In the illustrated embodiment, the movement device 30 is designed to contact the section 92 of the standing tree trunk 91, in particular to engage with the bark of the tree trunk 91. In detail, the movement device 30 has wheels 31 with spikes 32, the axes of rotation of which are arranged on the tree trunk 91 almost parallel to a longitudinal axis of the tree trunk 91, as shown in Fig. 2 to be recognized. Furthermore, the movement device 30 has a drive motor (not shown) for moving the wheels 31. Thus, the forestry device 20 can move helically upwards along section 92, as shown in Fig. 1 indicated by an arrow P1, and then move downwards as shown in Fig. 4 indicated by an arrow P2. In alternative embodiments, the motion device can be designed in a different way.

[0031] In detail, the machining tool 40 has a cutting tool 41 in the form of a saw, in particular a motor-driven saw. In the illustrated embodiment of the Fig. 1 Three cutting tools are visible. In alternative embodiments, the machining tool can have a single cutting tool, two cutting tools, or more than three cutting tools. The cutting tool 41 is designed to remove branches 93 from section 92, as shown in Fig. 2 to recognize. Thus, the forestry device 20 enables the processing, in particular delimbing, of section 92 while moving along it, especially during the helical upward movement.

[0032] Furthermore, the forestry device 20 enables the measurement of the geometric parameters GK of section 92, particularly during movement along it and / or processing of it. In detail, the measuring device 50 comprises at least one optical measuring element 51 in the form of a camera. In the illustrated embodiment of the Fig. 1 Three optical measuring elements are visible. In alternative embodiments, the measuring device can have a single optical measuring element, two optical measuring elements, or more than three optical measuring elements. The optical measuring element 51 is designed for optically measuring the geometric parameters GK of section 92. Additionally, the optical measuring element 51 is designed to optically detect the surface condition of section 92 and thus its health or damage, as well as its tree species. By moving the forestry device 20 helically upwards along section 92, the cameras measure the entire surface of the section.

[0033] In detail, the geometric parameters GK have at least one length L1, L2, L3, L4, at least one diameter D1x, D1y, D2, D3, D4, D5, at least one circumference U1, at least one ovality 01, and at least one curvature K1, K2, K3, K4, K5 of section 92. In alternative embodiments, the geometric parameters need not have all of these specific parameters and / or may additionally or alternatively have at least one contour of the section. The geometric parameters GK are interrelated. In detail, the diameters D1x, D1y are in mutually perpendicular directions, as shown in Fig. 3 to recognize by one in Fig. 1 The measurement is taken at the lower end of section 92. At the same level, the at least one circumference U1 and the at least one ovality O1, which describes a ratio of the diameter D1x to the diameter D1y, are measured. Furthermore, at the same level, the curvature K1 of section 92 is measured. After a measured length L1 along section 92 in Fig. 1 The diameter D2 and the curvature K2 of section 92 are measured upwards. After a measured length L2, a diameter D3 and a curvature K3 are measured. After a measured length L3, a diameter D4 and a curvature K4 are measured. After a measured length L4 and at a point in Fig. 1 At the upper end of section 92, a diameter D5 and a curvature K5 are measured. As in Fig. 1 As can be seen, section 92 is curved to the right after the measured length L2 and before the measured length L3, as described by the measured curvature K3.

[0034] In the illustrated embodiment, the measured geometric parameters GK have five curvatures K1, K2, K3, K4, and K5. In alternative embodiments, the geometric parameters can have specific parameters in the form of at least two curvatures, in particular at least three curvatures, or in particular at least more than five curvatures. The above statements regarding the specific parameters in the form of curvatures also apply to the other specific parameters in the form of length, diameter, circumference, ovality, and / or contour. In the illustrated embodiment, these geometric parameters GK enable the creation of a three-dimensional model of Section 92.

In the illustrated embodiment, the minimum diameter corresponds to the measured diameter D5 and defines the Fig. 1 and 4 upper end of section 92. The lower end of section 92 can be defined by a maximum diameter of the tree trunk 91 and / or root flares of the tree 90 and / or surrounding soil.

[0036] Furthermore, in the illustrated embodiment, the processing tool 40 for cutting through the tree trunk 91 is designed at least at the upper end of section 92.

In alternative embodiments, the processing tool can be designed to additionally or alternatively fell the tree trunk. In detail, the cutting tool 41 is designed in the form of saws 42 for cutting through the tree trunk 91. The saws 42 can be rotated from a vertical branch removal orientation to a horizontal branch removal orientation.

[0038] Furthermore, the forestry equipment system 10, or rather its forestry equipment 20, has a classification device 60. The classification device 60 is designed to divide section 92 into subsections 92-1, 92-2, and 92-3 based on the measured geometric parameters GK and value factors WF. At least one piece of information (Info) displays the divided subsections 92-1, 92-2, and 92-3, or their classification. Thus, the forestry equipment system 10 performs a yield determination itself. Additionally, the classification device 60 is designed to divide section 92 into subsections 92-1, 92-2, and 92-3 based on its recorded surface properties.

[0039] Furthermore, the forestry equipment system 10, or its forestry equipment 20, is designed to detect the distribution of branches 93 at section 92 by means of the measuring device 50 and the cutting tool 41.

In the illustrated embodiment, the measuring device 50 has at least one optical measuring element 51, and the distribution of branches 93 can be optically detected by means of the at least one optical measuring element 51. The distribution of branches 93 can be detected by means of the cutting tool 41 by measuring the power consumption of the cutting tool 41 or its drive motor. As in Fig. 1 As can be seen, section 92 has few or no branches 93 after the measured length L3 and before the measured length L4. Over the measured length L4, section 92 has many branches 93. The dividing device 60 is designed to divide section 92 into subsections 92-1, 92-2, and 92-3 based on the recorded distribution of branches 93. The distribution of branches can be part of a value factor or a value factor in itself.

[0040] The value factors WF can be specified. In particular, the classification device 60 has an input device 61 by means of which a forestry worker 100 and / or a forestry management system can specify the value factors WF.

[0041] In the illustrated embodiment, section 92 is divided into three subsections 92-1, 92-2, and 92-3.

In particular, marking MK-3 separates subsections 92-2 and 92-3. Marking MK-2 separates subsections 92-2 and 92-1. Marking MK-1 separates subsection 92-1 from a remaining part of the tree trunk 91. The at least one optical marking MK-1, MK-2, MK-3 enables the at least one piece of information (Info) to be visually perceived on the section 92 itself, in particular for processing the section 92 by the forestry worker 100.

[0043] In the illustrated embodiment, section 92 is divided into subsections 92-1, 92-2, and 92-3 by means of the division device 60 when the forestry equipment 20 is at the upper end of section 92. As it moves downwards, section 92 is marked with at least one MK-1, MK-2, or MK-3.
