Definitions

  • the present invention concerns a mobile tool carrier comprising a top, a front end, a back end and two sides, where the tool carrier comprises a drive unit connected to at least one track placed on either side of the tool carrier and at least one mounting interface configured to fasten at least one assembly, where the drive unit comprises at least one motor configured to at least drive the tracks and possibly the at least one assembly, when this is mounted, where each track is arranged on a wheel suspension comprising at least one driving wheel, where the tool carrier furthermore comprises a con- trol panel configured for remote control of the tool carrier and a mechanically adjustable mechanism configured for adjustment of the ground clearance on the tool carrier.
  • these tool carriers are driven by a diesel or gasoline motor, which is connected to the cutting assembly via a belt drive, a chain drive, or another coupling.
  • Such a tool carrier is the model TX1100 from the Lynex company, which is outfitted with a diesel-driven motor connected to a power take-off (PTO) and a hydraulic coupling placed at the front.
  • the tool carrier is furthermore outfitted at the front with a three -point suspension, which makes it possible to mount various processing assemblies, including a cutting assembly.
  • the tool carrier is furthermore closed off by several protective plates.
  • the tool carrier has a firmly mounted wheel suspension, on which the track is arranged.
  • the height of this tool carrier is a full 97 cm, of which at least two thirds of the motor and the corresponding motor suspension are placed above the track. This means that the tool carrier has a ground clearance of 27 cm and thus can travel on slopes of at most 50 degrees.
  • This wheel suspension does not allow an adjustment of the ground clearance, so that there is a risk of the tool carrier getting stuck on tree stumps and rocks.
  • the suspension on this Lynex TX1100 and other tool carriers is primarily designed to travel in one direction, which makes it hard for the tool carrier to travel in very hilly terrain.
  • the processing assembly is placed in front of the tracks, which means that the tool carrier has a total length of a full 1.70 m. This results in a poor weight distribution and an increased vertical movement of the processing assembly when moving over uneven terrain.
  • Another example of such a tool carrier is the model RC1000 from the Timan company, which is equipped with a diesel-driven motor connected to a hydraulic system.
  • the hydraulic system is furthermore connected to a hydraulically driven suspension and a hydraulic power take-off at the front. Both the top, the sides, and the back end are shielded with the aid of protective plates.
  • the tool carrier has a wheel suspension on which the track is arranged.
  • the height of this tool carrier is 68 cm, of which at least two thirds of the motor are placed over the track. This means that the tool carrier has a center of gravity of 20 cm and thus can only travel on slopes of at most 50 degrees.
  • the wheel suspension is fixed to the frame, so that it is not possible to adjust the ground clearance of the tool carrier.
  • the processing assembly is placed in front of the tracks, which means that the tool carrier has a total length of 1.31 m. This results in a poor weight distribution and an increased vertical movement of the processing assembly when moving over uneven terrain.
  • the point of rotation for the processing assembly is placed at the front, which means that the tool carrier will rotate when the processing assembly is raised and lowered. This means that the front of the slope mower will scrape against the ground when moving over uneven terrain.
  • Tool carriers such as the Lynex model TX2500, how to use hydraulic pistons placed between the wheel suspension and the frame for adjustment of the ground clearance. These hydraulic pistons are often exposed to a very dirty environment, especially if the tool carrier is outfitted with chopper mowers, where there is a risk of the pistons getting stuck on account of cuttings, dust, dirt and the like.
  • Tool carriers with an automatically adjustable ground clearance are known from US 2004/0168837 Al and US 2008/0223630 Al. Both of the tool carriers are configured with 4 tracks, the ground clearance of the tool carrier being changed by pivoting the individual tracks about a point within the area spanned by the individual track. The pivoting of the tracks requires an accurate control by a controller (robot guidance).
  • the drawback of these tool carriers is that, as the ground clearance increases, so does the height where the part of the tool carrier constituting the body (the part which is not the track) is situated.
  • the height at which the body is situated increases so that an ever increasing portion of the body is placed above the track.
  • the tool carrier In order to work on slopes, the tool carrier must adjust the tracks so that the body is held in a vertical position. This means that the tool carrier when working on slopes or in uneven terrain must continually adjust the pivoting of the individual tracks. This may mean that the speed of the functions performed is reduced and the quality of the work may be worse if the tool carrier does not maintain an even speed.
  • the contact surfaces with the ground will be decreased when the ground clearance increases, which creates a greater pressure on the contact points.
  • One purpose of the invention is to provide a tool carrier which solves the aforemen- tioned problems.
  • Another purpose of the invention is to provide a tool carrier which makes it possible to adjust the ground clearance in a simple and easy manner.
  • Yet another purpose of the invention is to provide a tool carrier comprising an adjustment mechanism which minimizes the risk of the mechanism getting stuck.
  • the present invention concerns a mobile tool carrier as described in the introduction and which is characterized in that the mechanically adjustable mechanism comprises a primary support element for a first mounting of the wheel set, which gives the tool carrier a first ground clearance, and where the mechanically adjustable mechanism furthermore comprises at least one removable support element for at least a second mounting of the wheel set, where the at least one removable support element in combination with the primary support element gives the tool carrier a second ground clearance.

  • processing is meant an action which is performed directly or indirectly on the ground surface or an object, such that it is converted from one condition to another.
  • fastening of an assembly is meant that the assembly can be mounted on or mechanically connected to or otherwise fastened to the tool carrier.

  • the drive unit may thereby have a compressed design, such that the height of the drive unit, and possibly the assembly, more or less corresponds to the height of the tracks.

  • the drive unit may comprise a Wankel motor or an electric motor, which takes up less room and weighs less as compared to other carriers which use a gasoline motor.
