Description

BACKGROUND OF THE INVENTION The invention relates to material collecting devices. In particular, the invention relates to a detachable device for collecting material.

Equipment for the collection of materials and waste is needed at various construction sites to facilitate the cleaning of the environment and the work area. It is generally known to use a vacuum cleaner mounted on a work machine to collect smaller materials, which is used to suck crushed stone, for example, into the tank of the device via a suction hose. When the tank is full, it is emptied through a separate drain hole. A magnet is usually used to collect metallic materials.

The problem with the arrangements described above is that these equipment used to collect materials cannot be utilized to collect larger and non-metallic debris such as pieces of board, insulation and plastics. Larger materials easily clog a suction hose with a small cross-sectional area, and the suction power is also not sufficient to collect such materials. In this case, the materials have to be collected by hand, which is slow and requires a lot of labor. It is also important to avoid the accumulation of unnecessary stones and sand in the collection materials, as the waste is paid for by weight. Prior art solutions are disclosed in JP 2007146470 A, US 2008010775 A1, DE 29508516 U1, US 5254146 A, US 2018055316 A1, US 5588179 A and JP 2008115610 A.

Brief description of the invention The object of the invention is thus to develop an apparatus so that the above-mentioned problems can be solved. The object of the invention is achieved by a device, N of which is characterized by what is stated in the independent claims. Some preferred embodiments of the invention are the subject of dependent claims. = The invention is based on a new idea, in which a device has been developed with which large-sized materials can also be sucked directly into the collection tank through a nozzle opening in the collection tank. When the tank is full, it is emptied through the nozzle opening used for suction. N The device according to the invention has the advantage of facilitating and accelerating the collection of large-sized materials and waste in site conditions. When using the device according to the invention, labor costs are reduced when the device handles the collection of materials. The suction power of the device according to the invention can be increased or decreased by means of an adjustable nozzle opening, which diversifies the use of the device. Other advantages of the solution will be returned in connection with the description. BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail in connection with preferred embodiments, with reference to the accompanying drawings, in which: Figure 1 is a cross-sectional side view of a device according to an embodiment of the invention with the collection nozzle open; Figure 2 is a cross-sectional side view of a device according to an embodiment of the invention with the lid closing in half at the nozzle opening of the collection container; Figure 3 shows a side view of a cross-section of a device according to an embodiment of the invention with the lid completely closing the nozzle opening; and Figure 4 shows a side view of the structure of a device according to an embodiment of the invention from the outside, with the lid closing the nozzle opening of the collecting container in half.

DETAILED DESCRIPTION OF THE INVENTION Fig. 1 shows a cross-section of a device removably fitted to a working machine according to an embodiment of the invention with the nozzle opening 3 of the collecting container 1 of the device open. The device can be used to collect various materials. In this specification, material generally refers to materials that can be collected, such as various debris, construction waste, stones, boards, insulation, and N 25 plastics. The working machine can be any known working machine, such as an excavator or N other similar machine. In one embodiment, the device can be attached to the boom end of the implement 3 or to some other suitable location. The implement can be fastened to the implement with quick-release fasteners or some other suitable fastening method. = Examples of implements where the implement can be used are 3 30 Crane, Wheel Loader and Tractor. For example, on a tractor, the implement can be attached to its front loader or to a three-point hitch. In an excavator, the device can be attached to the bucket. N The device may comprise a body 2 which forms a collection container 1 for receiving material. In one embodiment, the body 2 comprises a top part, a bottom part and four side parts. The body may also have other shapes, such as round or angular. The collecting tank 1 and the nozzle opening 3 must be large enough to be able to receive even large material. The device may further comprise a vacuum unit 4 attached to the body 2 to provide suction. As can be seen in Fig. 1, the vacuum unit 4 can be fitted to the upper part of the body 2 so that the lower suction side of the vacuum unit communicates with the collecting tank 1, allowing suction flow from outside the collecting tank 1 into it.

In addition to the above, the device may comprise an adjustable nozzle opening 3 in the body 2, through which the vacuum unit 4 is adapted to suck material into the collecting tank 1 and through which the material is removed from the collecting tank 1. In one embodiment, the collecting tank 1 has only one opening and through which it is removed. The nozzle opening 3 can be located in the side part of the body. In the embodiment according to Figure 1, the nozzle opening 3 is located on the left edge when viewed from the viewing direction. In one embodiment, the nozzle opening 3 comprises at least a part of one side part of the body 2 and is open up to the bottom part of the body 2, allowing unobstructed passage of material into the collection container 1 and storage in the collection container 1. In one embodiment the nozzle opening 3 comprises the whole side part. By means of the adjustable nozzle opening 3, the size of the nozzle opening 3 can be increased so large that large waste can also fit inside the collection tank 1.

To close and open the nozzle opening 3, a closing and opening mechanism 5 can be arranged in the nozzle opening 3. According to one embodiment, the closing and opening mechanism 5 can be arranged to open the nozzle opening 3 at least partially to suck 3 for emptying. In this case, the nozzle opening is at least partially open during suction, but during transfer or transport it can be closed to prevent the material from falling N when the device is moved to the emptying place.

N The nozzle opening 3 can be completely open during suction, in which case 7 large debris can also fit inside the collection tank 1. At the discharge point, the nozzle opening A 30 3 is opened and the material is removed through the nozzle opening. If necessary, the device is tilted to facilitate emptying. In one embodiment, the device can be adapted to adjust the suction power by opening and closing the nozzle opening 3 as required. Closing and opening can be done mechanically or automatically. The nozzle opening can be opened stepwise or steplessly. Hydraulics can be used to adjust the nozzle opening. In one embodiment, the closing and opening

the mechanism 5 may comprise a lid 6 for closing the nozzle opening 3. The lid 6 can be slid over the nozzle opening either partially or completely. In one embodiment, the device is formed in such a way that the lower edge 6a of the lid 6 and the edge 2a of the bottom part of the body 2 form gripping lips to allow a press grip on different materials. The gripping lip can be gripped by squeezing various materials, such as larger plastic strips, and transferred to a waste bin, for example, so that during the transfer the material is not at least completely in the collection container but hangs at least partially outside the collection container 1.

Figure 1 shows a device according to an embodiment, in which the nozzle opening 3 of the collecting tank 1 is completely open with the lid 6 turned to the side above the nozzle opening 3. Fig. 2 shows a cross-sectional view of a device according to an embodiment with the lid 6 closing the nozzle opening 3 of the collecting container 1, the closing and opening mechanism 5 of the nozzle opening 3 being in the adjustment range, allowing the suction power of the device to be adjusted. Figure 3 shows a cross-section of a device according to an embodiment with the lid 6 completely closing the nozzle opening 3, whereby the device can be moved or transported, for example, to an emptying place or another work station while the material remains safely in the collection container 1.

A flap 6b can be fitted to the lower edge 6a of the cover 6. The flap 6b can be - adapted to close the gap between the lower edge 6a of the cover 6 and the edge 2a of the bottom part of the body 2 before the lower edge 6a of the cover 6 contacts the edge 2a of the bottom part of the body 2. Such a situation is shown in Figure 2. Between the front wall and the back wall of the lid 6, from the lower edge of the lid towards its upper edge, there is a channel or slot along which the material is then sucked. This channel thus acts as a flow path in this situation, which allows flow to the collecting tank 1. The flap 6b thus reverses the flow upstream after the nozzle opening N 3 between the lower edge of the front wall and the edge of the bottom of the body.

N As the flow passes along the channel 7 between the front wall and the back wall of the lid, the material travels and after the lid 6 in the collecting tank 1 they A 30 fall to the bottom of the collecting tank 1. In the mouth and channel, the flow rate E is high, which transports the material through the channel. After the channel, the flow area in the collecting tank 1 <increases and the flow rate thus decreases. In this case, the flow of material D with the flow is reduced and it falls to the bottom of the collection tank. = For example, plastic and other light material may tend upwards towards the vacuum unit, but this can be prevented by the duct solution.

The flap 6b may be, for example, rubber or some other flexible material. On the other hand, the flap 6b can also be of a rigid material, such as a steel or aluminum plate, in which case it can be hinged to the lower edge 6a of the cover 6.

In the situation of Fig. 3, the lower edge 6a of the cover 6 is against the edge 2a of the bottom part 5 of the body 2. The flap 6b may be between the lower edge 6a of the cover 6 and the edge 2a of the bottom part of the body 2. Since the lower edge of the front wall of the cover 6 abuts the edge 2a of the bottom part of the body 2, no flow can flow along the channel between the front wall and the rear wall of the cover 6 either. The lid 6 thus completely closes the flow opening 3.

According to one embodiment, the device may further comprise a separation unit 7 with which the air and / or dust flow can be separated from the material remaining in the collection tank 1. The separating unit 7 can be located inside the collecting tank 1 between the vacuum unit 4 and the nozzle opening 3 or below the vacuum unit 4. In one embodiment, the separation unit 7 may be a filter or a cyclone.

According to one embodiment, the filter of the separation unit is formed by a net, such as a steel net, having a mesh size of, for example, 2-20 mm. Such a filter allows, for example, dust and sand to pass through, leaving only larger debris in the collection tank 1, which is emptied from the collection tank onto the waste bin. This prevents the device from collecting material that is not intended to be taken to a waste collection, for example. Instead of a steel mesh, a filter cloth can also be used as a filter.

According to one embodiment, the device may further comprise a suction outlet 8, into which a suction hose can be fitted for sucking material into the collecting container 1 with the nozzle opening 3 closed. Alternatively, the suction hose can be used to suck the material into the collecting tank 1 instead of the nozzle opening 3. In this case, the nozzle opening 3 is completely closed. However, the collecting tank 1 can be emptied through the nozzle opening 3. When the material is collected through the nozzle opening 3, the suction N outlet 8 is closed, for example by a flap or plug.

7 According to one embodiment, the device is hydraulically operated. In one embodiment A 30, the vacuum unit 4 further comprises a hydraulic motor 9. Figure 4 shows the structure of a device according to an embodiment of the invention seen from the outside, in which the closing and opening mechanism 5 of the nozzle opening 3 of the device may further comprise a hydraulic cylinder 10. The hydraulic cylinder 10 can be adapted to adjust the suction power by opening and closing the lid hydraulically.

N 35 If desired, the device can also be electrically operated, for example. In this case, the vacuum unit 4 has an electric motor instead of a hydraulic motor 9. Similarly,

the closing and opening mechanism 5 may have an electric cylinder in place of the hydraulic cylinder 10. The means for moving the lid 6 can also be mechanical. The lid 6 can also be adapted to close with suction pressure. The device can be adapted to draw its operating energy from the implement. The hydraulic drive can thus be connected to the implement's hydraulic system. Correspondingly, for example, an electrically operated device can be connected to the electrical system of the work machine. It will be apparent to one skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments - are thus not limited to the examples described above but may vary within the scope of the claims.
