Description

[0001] The invention relates to a transport cart for use with an excavator, wherein the transport cart facilitates at least one transport of a load, for example bulk or piece goods.

[0002] To simplify work with excavators and loaders, especially wheel loaders and skid steer loaders, a wide variety of attachments and additional devices are available for these machines. Among other attachments, excavators have attachments that can be attached to a boom mount, such as various buckets, drilling rigs, grapples, and the like. Attachments for excavators also exist that can be mounted on the excavator's chassis-side attachment mount, with a dozer blade typically mounted and attached to the chassis-side attachment mount. Due to specific design features, attachments and additional devices that can be used with excavators are not usually suitable for loaders.

[0003] During earthmoving work, on construction sites, in gardening, or similar activities, it is often necessary to move relatively large quantities of material. In earthmoving work, for example, this is excavated material; in gardening and landscaping work, this is often green waste. With the current state-of-the-art attachments and additional equipment for excavators, it is not possible to effectively move the material to be transported using the excavator alone. While there are roll containers that can be attached to the excavator's chassis-side attachment mount, allowing the excavator to move material, these are inflexible and severely restrict the excavator's mobility.Furthermore, coupling and uncoupling these devices requires precise alignment between the excavator chassis and the roll container, as well as sufficient maneuvering space for the excavator, so that such roll containers are not suitable, or only suitable to a very limited extent, in areas with limited maneuvering space. A transport trolley according to the preamble of claim 1 is known from document WO 2013 / 138907 A1.

[0004] It is therefore considered an object of the present invention to provide a transport trolley which can be moved by the excavator independently of the orientation of the excavator chassis to the transport trolley.

[0005] This object is achieved according to the invention in that the transport trolley has a functional section, a chassis section and a coupling section, wherein the functional module is fixed to the transport trolley in the functional section, wherein at least one chassis element is arranged in the chassis section, wherein the transport trolley stands on the at least one chassis element when used as intended and movement of the transport trolley on a surface is facilitated by the chassis element, wherein a tilting axis of the transport trolley runs through the chassis element, wherein at least one coupling means is arranged in the coupling section, wherein by means of the coupling means the transport trolley can be fixed to a device holder of a boom of the excavator and a manipulation force of the excavator can be introduced into the transport trolley at a force application point of the coupling means.Such a design of the transport cart according to the invention enables an excavator, in particular a so-called mini-excavator, to use the transport cart in a manner similar to the use of a wheelbarrow by a person. The invention provides that the transport cart is designed such that it can be both pushed and pulled by the excavator using the excavator's boom. Furthermore, it is also possible and provided according to the invention for the transport cart to be adapted to the excavator in such a way that it can be lifted to a site by the excavator, at least in an unloaded state.

[0006] An advantageous implementation of the inventive concept provides that a total weight force of the transport trolley acts at an overall center of gravity of the transport trolley, wherein a product of an amount of the total weight force and a horizontal overall center of gravity distance from the tilting axis is less than or equal to a product of an amount of the manipulation force and a horizontal force application point distance from the tilting axis, so that a lever is formed by the transport trolley, so that a load can be manipulated by the excavator which exerts a weight force that is greater than the maximum manipulation force that can be exerted by the excavator. It is possible and provided according to the invention that both a one-sided and a two-sided lever can be formed by the transport trolley.

[0007] An advantageous embodiment of the invention provides that the coupling means is designed such that it can be used with a quick-change system for excavator attachments.

Advantageously, the invention provides that at least one support foot or support skid is arranged in the chassis section at a distance from the chassis element in order to prevent the transport trolley from tipping over.

[0009] It is also possible, and provided by the invention, for the wheel to be operatively connected to a device for self-propelling the transport cart, for example, a hydraulic motor, an electric motor, or the like. The hydraulic motor can be driven, for example, by the excavator's hydraulic system. Furthermore, it is also possible, and provided by the invention, for wheels to be designed to be steerable.

[0010] An advantageous implementation of the inventive concept provides that the functional section of the transport trolley has a first connecting means, wherein the functional module has a second connecting means, wherein the first connecting means and the second connecting means are adapted to one another in such a way that the functional module can be secured to the transport trolley in the functional section by means of the connecting means. The connecting means can in particular have a mechanical coupling, a magnetic coupling, a friction clutch, a hook, or the like. It is also possible for the connecting means to be designed in the manner of a container coupling, a so-called twistlock.

[0011] An advantageous embodiment of the invention provides that at least one guide means is arranged in the functional section, wherein the guide means supports the intended alignment of the functional module in relation to the functional section of the transport trolley when the functional module is secured to the transport trolley.

[0018] An advantageous implementation of the inventive concept provides that the functional module is designed, at least in sections, as a sieve, so that only loads of a certain minimum load size remain in the load receiving element. It is also possible, and provided according to the invention, for the functional module designed as a sieve to have multiple sieve levels, with each sieve level being able to sieve out a load of different grain sizes, thus enabling, for example, the fractionation of bulk material.

[0019] An advantageous embodiment of the invention provides that the functional module has a concrete bucket section, wherein a bucket surface of the concrete bucket section is designed such that processing of concrete in the concrete bucket section is facilitated. It is envisaged that processing of concrete by the concrete bucket section of the transport trolley according to the invention can be facilitated in several ways. Firstly, the invention provides that the concrete bucket section has rounded corners on all sides, since this minimizes the risk of areas being formed in the concrete bucket section that cannot be covered by a stirring tool used for concrete production.In a particularly advantageous embodiment of the concrete bucket section of the transport trolley according to the invention, the concrete bucket section and a mixing tool used are adapted to one another in such a way that all areas of the interior of the concrete bucket section surrounded by the concrete bucket section can be covered by the mixing tool. To facilitate concrete processing, it is also provided that the concrete bucket section is easy to clean and / or resistant to cleaning agents and / or cleaning methods for removing dried concrete.This can also be achieved according to the invention in that the concrete bucket section is either made of a chemically resistant and deformable plastic, which allows the dried concrete to be released from the concrete bucket section by deforming it, or in that the concrete bucket section is made of a metallic material, which can also be cleaned with the aid of, for example, a hammer and chisel.

[0020] In an advantageous embodiment of the transport cart according to the invention, the concrete bucket section is removable from the functional module, so that mixed concrete can be transported to a processing location independently of the transport cart. In such an embodiment of the transport cart according to the invention, the concrete bucket section can be used as a standalone concrete bucket. This is particularly advantageous if the transport cart is to be used in a difficult-to-access and / or heavily trafficked work area, for example, inside a house, in a small garden, in a forest, or in similar locations.

[0021] An advantageous implementation of the inventive concept provides that the functional module has a combustion device, wherein the combustion device has at least one combustion chamber and an ash pan, wherein plant waste can be combusted in the combustion chamber of the combustion device and wherein ash accruing during the combustion of the plant waste is collected in the ash pan. Furthermore, the invention provides that the combustion device has heat protection in the areas facing the transport trolley, so that the risk of damage to the transport trolley due to thermal energy released during combustion is reduced.

[0022] An advantageous embodiment of the invention provides that the combustion device has a closable filling opening, at least one air supply opening, and at least one exhaust air opening. Combustible material can be introduced into the combustion chamber through the filling opening, fresh air can be introduced into the combustion chamber through the air supply opening, and exhaust gases can be discharged from the combustion chamber through the exhaust air opening. In a particularly advantageous embodiment of the transport trolley, the air supply opening and the exhaust air opening are adapted to one another in such a way that a chimney effect is promoted within the combustion device, thus promoting the combustion of the plant waste.It is also possible and provided according to the invention that the filling opening can have a lock mechanism by means of which the combustion chamber can be sealed against ambient air when the fuel is filled in, so that when the fuel is filled in, a disturbance of flow conditions within the combustion chamber is minimized and / or an escape of combustion gases from the combustion chamber through the filling opening is prevented.

[0023] In an advantageous embodiment of the transport cart according to the invention, the filling opening is closed by means of a lid arranged above the combustion chamber, with the exhaust air opening being arranged on the lid. With such a configuration of the transport cart according to the invention, it is particularly advantageous that even very large objects can be placed in the combustion chamber for combustion, for example, undergrowth, tree stumps, branches, or the like. In a particularly advantageous embodiment, a projection of the lid onto a combustion chamber cross-section is approximately congruent with the combustion chamber cross-section, so that the entire combustion chamber can be opened through the lid.

[0024] An advantageous implementation of the inventive concept provides for an exhaust element to be arranged at the exhaust air opening. The invention provides that the exhaust element can be designed in such a way that the chimney effect is promoted within the combustion device. Furthermore, it is also provided that filter elements, sensors or the like can be arranged in the exhaust element in order to change and / or monitor the composition of the combustion gases produced during combustion. In a particularly advantageous embodiment of the combustion device of the functional element of the transport trolley according to the invention, the filter element has a catalytic converter by means of which chemicals can be removed from the exhaust gas.

[0025] An advantageous embodiment of the invention provides that the ash pan has at least one sieve element, wherein the sieve element can be used to fractionate solid combustion residues arising during the combustion of plant waste according to particle size. Furthermore, the invention provides that the ash pan can also have magnets by means of which ferromagnetic components can be separated from the ash. This is particularly advantageous when, for example, boards with nails and / or screws are burned.

[0031] An advantageous implementation of the inventive concept provides that the excavator system has a transport cart as described above with a concrete bucket section and a mixing bucket, wherein the mixing bucket has a bucket coupling section and a mixture receiving section, wherein the mixture receiving section is adapted to the concrete bucket section of the transport cart such that when the concrete bucket section is scooped out with the mixing bucket, a continuous contact line can always be formed between the mixture receiving section and the bucket surface, thus enabling complete emptying of the concrete bucket section by means of the mixing bucket. Such combinations of a container and a removal device are known, for example, from the field of kitchen appliances.

[0032] According to the invention, it is advantageously provided that the excavator system comprises a transport cart according to the invention with a combustion device and a loading fork, wherein the loading fork has a tine section and a fork coupling section, wherein the loading fork can be fixed to the device holder of the boom of the excavator by means of the fork coupling section.This excavator system can advantageously be used in such a way that, with the aid of the excavator, the transport trolley with the combustion device is first positioned on a construction site. The transport trolley is then uncoupled from the excavator, advantageously with the aid of a hydraulic quick-change system. The loading fork is then removed from a fork holder advantageously arranged on the combustion device and coupled to it using the quick-change system. The cover of the filling opening is then opened with the loading fork. The combustion chamber is then fed with the fork through the filling opening, and finally the furnace door is closed with the fork. By using a fork instead of, for example, a hydraulic grab, the costs of manufacturing the excavator system can be significantly reduced, since the loading fork does not require any hydraulic components.

[0033] In the following, some embodiments of the inventive concept are explained in more detail, which are shown in the drawing.

[0034] They show: Figure 1 a schematic representation of a transport trolley with a functional module, Figure 2 a schematic representation of a transport trolley with two functional modules with different load-carrying devices, Figure 3 a schematic representation of a transport trolley with a functional module with concrete bucket section, Figure 4 a schematic representation of a transport trolley with a functional module with a trough and a functional module with an incineration device, Figure 5 a schematic representation of a transport trolley with a functional module with a combustion device, Figure 6 a schematic representation of an excavator system consisting of an excavator and a transport cart, Figure 7a schematic representation of an excavator system for mixing concrete and Figure 8 a schematic representation of an excavator system for scooping out concrete.

[0035] In Figure 1 A schematic representation of a transport trolley 1 according to the invention is shown. The transport trolley 1 has a functional section 2, a chassis section 3, and a coupling section 4.

[0036] Two chassis elements 5 are arranged in the chassis section 3, on which the transport trolley 1 rests. The chassis elements 5 each have a wheel 6, so that the chassis element 5 facilitates the movement of the transport trolley 1 on a surface 7. A tilting axis 9 of the transport trolley 1 runs through a hub 8 of the wheel 6.

[0037] A coupling means 10 is arranged in the coupling section 4 of the illustrated transport trolley 1, by means of which the transport trolley 1 can be secured to an implement holder 11 of a boom 12 of an excavator. By means of the coupling means 10, a manipulation force 13 of the excavator can be introduced into the transport trolley 1 at a force application point 14 of the coupling means 10. The coupling means 10 of the illustrated transport trolley 1 can be used with a quick-change system for excavator attachments.

[0038] In functional section 2, a functional module 15 is fixed to the transport trolley 1. The functional section 2 of the transport trolley 1 has a first connecting means 16, which is designed as a tensioning bracket closure. The functional module 15 has a second connecting means 17, which is designed as a counter-hook to the first connecting means 16, which is designed as a tensioning bracket closure. In the functional section 2, a guide means 18 designed as a guide pin is arranged, which is inserted into a guide pin receptacle (not designated) of the functional module. The guide means 18 supports the intended alignment of the functional module 15 in relation to the functional section 2 of the transport trolley 1. The functional section 2 of the illustrated transport trolley 1 is designed such that a second functional module 15 can also be arranged in the functional section 2.

[0039] A total weight force 20 of the transport trolley 1 acts at an overall center of gravity 19 of the transport trolley 1. A product of the total weight force 20 and a horizontal total center of gravity distance 21 from the tilting axis 9 is less than or equal to a product of the manipulation force 13 and a horizontal force application point distance 22 from the tilting axis 9. As a result, the transport trolley 1 forms a one-sided lever, by means of which the excavator can manipulate a load that exerts a weight force greater than the maximum manipulation force 13 that can be exerted by the excavator.

[0040] At the Figure 2In the transport trolley 1 according to the invention shown, the functional modules 15 have load-receiving means 23. One of the load-receiving means 23 is designed as a trough 24 through which a bulk material 25 is received. In the other functional module 15, the load-receiving means 23 are designed as stanchions 26, with a piece of goods 27 arranged between the stanchions 26. The trough 24 also has a section designed as a sieve 28 through which components of the bulk material 25 that fall below a defined minimum load size fall.

[0041] The Figure 3 The embodiment of a transport trolley 1 according to the invention shown in FIG. 1 has, unlike the embodiment shown in Figure 2 , and similar to those in Figure 1The embodiment shown has only one functional module 15 arranged in the functional section 2. The functional module 15 has a concrete bucket section 29. The concrete bucket section 29 is designed as a mortar tub that can be removed from the functional module 15. The concrete bucket section 29 has crane eyes 30, by means of which the concrete bucket section 29 can be lifted by a crane or an excavator using a lifting gear, so that concrete mixed in the concrete bucket section 29 can be transported to a processing location independently of the transport cart 1.

[0042] The concrete bucket section 21 is made of high-density polyethylene, so that the bucket surface 31 is particularly resistant to erosion wear that occurs during concrete mixing and is highly resistant to the chemicals contained in the concrete. Furthermore, a mixing chamber 32 enclosed by the concrete bucket section 29 has rounded corners and edges, minimizing the risk of unmixed concrete accumulating in the corners and edges of the mixing chamber.

[0043] The Figure 4The embodiment of a transport trolley 1 according to the invention shown has two functional modules 15. One of the functional modules 15 has a load-receiving means 23 designed as a trough 24 with a sieve 28. The other functional module 15 has a combustion device 33 for burning plant waste. The combustion device 33 has a combustion chamber 35 surrounded by a housing 34. Below the combustion chamber 35, an ash box 36 is arranged, in which ash produced during the combustion of the plant waste is collected.

[0044] The housing 34 has a lid 37 through which the combustion chamber 35 can be filled. The lid 37 is designed like a hood and, when opened, exposes the entire combustion chamber 35, so that even large-volume plant waste can be arranged in the combustion chamber 35.

[0045] Above the ash pan 36, the combustion device 33 has air inlet openings 38 through which fresh air can flow into the combustion chamber 35. The cover 37 of the combustion device 33 has an exhaust air opening 39 through which exhaust gases can flow out of the combustion chamber 35. A chimney 40 is flanged to the exhaust air opening 39. By means of a chimney cover, the chimney minimizes the escape of sparks and ash from the combustion chamber 35 and the entry of precipitation, in particular rain, into the combustion chamber 35. In the combustion chamber 35, a piece of waste to be burned is arranged, for example, on a grate 41.

[0046] The Figure 5 The embodiment of a transport trolley 1 according to the invention shown has a combustion device 33 which, compared to the one shown in the Figure 4shown combustion device 33 is modified. A filling grate 42 and a floor grate 43 are arranged within the combustion chamber 35. Above the filling grate 42, a first combustion zone 44 is formed, into which added plant waste is first dried and partially burned. A second combustion zone 45 is formed between the filling grate 42 and the floor grate 43. When further plant waste is added, the waste added first is moved to the second combustion zone 45, where the final combustion takes place. In the illustrated embodiment of the transport cart 1 according to the invention with combustion device 33, a sieve element 46 is arranged between the ash box 36 and the combustion chamber 35. The sieve element 46 has magnetic properties, so that ferromagnetic components, for example screws and / or nails, can also be sieved out of the ash by means of the sieve element 46.Circular air supply openings 38 are arranged between the sieve element 46 and the floor grate 43.

A gas cylinder 49 for supplying the burner 48 with a fuel gas is arranged in a thermally shielded gas cylinder receptacle 50 of the combustion device 33.

[0048] In order to improve the quality of the exhaust gases of the combustion device 33, the combustion device 33 has an exhaust element 51 flanged to the exhaust air opening 39, wherein a filter element 52 is arranged in the exhaust element 51. Unlike in the Figure 4 In the embodiment shown, the exhaust air opening 39 is not arranged on the cover 37, but on the housing 34 of the combustion device 33.

[0049] In Figure 6A schematic representation of an excavator system 53 consisting of a transport cart 1 and an excavator 54 is shown. The transport cart 1 has two functional modules 15
