Detailed Description

The apparatus for collecting and transferring material and the method of collecting and transferring material using the apparatus according to the present invention will be described with reference to the accompanying drawings and specific embodiments, which are intended to schematically illustrate and describe the technical solution of the present invention and not to limit the present invention.

Figures 1 to 3 show generally one example of a device according to the invention, generally indicated at 100. The apparatus 100 is, for example, a reclaiming/discharge shovel apparatus.

As shown in fig. 1 to 3, the apparatus 100 may comprise a tank 1, which tank 1 may comprise a bottom 11, a circumferential wall 12 and a top 13. The bottom 11, the circumferential wall 12 and the top 13 enclose an inner space for containing material. The tank 1 has a plurality of apertures 14 in the top 13 to enable material, for example in powder or granular form, to enter and exit the interior space of the tank 1. The case 1 may have a substantially rectangular parallelepiped, substantially cubic, or substantially cylindrical shape. In the embodiment shown in fig. 1 to 3, the case 1 has a substantially rectangular parallelepiped shape.

The plurality of through holes 31 and their spacing in the screen plate 3 and the plurality of apertures 14 and their spacing in the top 13 of the tank 1 are sized and arranged such that each through hole 31 can be aligned with (e.g. substantially aligned with the centre of) or coincide with a respective aperture 14 and the apertures 14 can be shielded by means of the spacing between the through holes 31 in the event of a slight displacement of the screen plate 3. Furthermore, the bore diameter of the through-opening 31 can be smaller than the size of the opening 14, so that the material to be collected and transferred can be screened for particle size while being collected or removed.

Preferably, the screen plates 3 are designed to be replaceable, so as to allow screening and collection of different material particle sizes, and in addition, such a design is also advantageous for long-term use and maintenance of the apparatus 100, for example, in the case of a broken or aged screen plate 3, only the screen plate needs to be replaced with a new one, and the entire apparatus does not need to be replaced.

The apparatus 100 may also include a screen panel 3 that is preferably disposed immediately adjacent or flush against the top 13 of the tank 1. The screen plate 3 may have a plurality of through holes 31. The screen 3 is movable between an open position in which the through holes 31 in the screen 3 are substantially aligned with the apertures 14 in the top 13 of the tank 1, thereby allowing material to be fed into or discharged from the internal space of the tank 1; in the closed position, the through holes 31 in the screen plate 3 are staggered from the apertures 14 in the top 13 of the box 1, thereby preventing material from entering or leaving the interior space of the box 1, and also preventing material from contaminating the environment and preventing external contaminants from affecting the material.

In the embodiment shown in fig. 1 to 3, the top 13 of the box 1 and the screen 3 have a substantially rectangular shape. In this embodiment, guide slots 15 are provided on both sides (e.g. the short sides) of the top 13, respectively, and correspondingly, opposite side edges of the screening deck 3, e.g. on the short sides of the screening deck 3, may be seated in the guide slots 15, so that the screening deck 3 can slide along the surface of the top 13 between the open and closed positions. Switching of the screening deck 3 between the open position and the closed position is thus achieved with a simple construction and operation.

It is also conceivable that the top 13 of the box 1 and the screening deck 3 have a substantially square or substantially circular shape, or have other polygonal shapes, as long as it is achieved that the opposite side edges of the screening deck 3 can slide along the guide slots 15 provided in the top 13.

The top 13 of the tank 1 may be configured to form an angle a with the bottom 11 so that the top 13 extends obliquely with respect to the bottom 11. The angle a may be in the range of 20 to 70 degrees, preferably in the range of 40 to 50 degrees, for example 45 degrees. It is thus possible to control the sliding of the screen 3 along the guide slots 15, in particular against the surface of the roof 13, automatically switching between the open and closed positions by controlling the orientation of the box 1 and by means of the weight of the screen 3 itself.

The top 13 of the box 1 may also be provided with a stop portion 16 for limiting the displacement of the screen plate 3. The stop portion 16 stops the further movement when the screen panel 3 is moved to a position where the through holes 31 in the screen panel 3 are properly misaligned with the apertures 14 in the roof 13, i.e. moved to the closed position.

The device 100 may further comprise that the device further comprises an outlet 17 (see fig. 3) arranged in the top 13 and a shutter 2 connected to the top 13. The shutter 2 is movable between a deployed position (shown in fig. 3) in which the shutter 2 exposes the outlet 17 in the top 13 for discharge, and a shielding position (shown in fig. 1 and 2) in which the shutter 2 covers the outlet 17 in the top 13 to facilitate better discharge while preventing loss of material or contamination of the environment prior to discharge, and to protect the material in the tank 1 from external contaminants, such as dust and impurities.

In one embodiment, the shutter 2 is configured in the form of a flap, such that the shutter 2 can be flipped between the deployed position and the shielding position. In the embodiment shown in fig. 1-3, one side (e.g., the long side, hereinafter referred to as the "connecting side") of the cover 2 is pivotally connected to a pin 18 located on both sides (i.e., the short side) of the top 13. It is also conceivable that the attachment side of the cover 2 is mounted on a transverse axle in the middle of the top 13 or is connected to the top 13 by a hinge. Thereby, switching of the shutter 2 between the deployed position and the shielding position is achieved with a simple structure.

Advantageously, the connecting side of the cover 2 to the tank 1 or to the roof 13 can also serve as the aforementioned stop portion 16. Other forms of separate stop portions are of course also conceivable, such as protrusions (not shown) in the surface of the top portion 13.

Furthermore, in the embodiment shown in fig. 1 to 3, the device 100 further comprises a handle 5. The handle 5 may be in the form of an integral part of the housing 1. Alternatively, the handle 5 may be mounted on the case 1 as a separate component. In this case, the handle 5 may comprise a grip portion 51 and a connecting portion 52, one end of the connecting portion 52 being fixedly connected with the circumferential wall 12 of the tank 1 and the other end being connected with one end of the grip portion 51 in a relatively adjustable manner, for example an adjustable bolt arrangement or a telescopic sleeve, so that the grip portion 51 can form an adjustable angle b and/or a telescopic length with the connecting portion 52. Thus, the use of the handle 5 facilitates easy access to the device 100, facilitates adjustment of the orientation of the case 1, and the adjustable handle makes it easier to adapt to different environmental spaces for access/discharge and to operate the device 100 in a more ergonomic manner.

To facilitate directing material into the tank 1 when collecting the material and directing material out of the tank 1 when transferring to a destination, the apparatus 100 may further include a blade 4 mounted on the tank 1. Blade 4 may include a main portion 41 and two fence portions 42 on either side of main portion 41, where main portion 41 may extend outwardly from where circumferential wall portion 12 abuts top portion 13, and where two fence portions 42 extend generally perpendicularly from either side of main portion 41, thereby providing blade 4 with a "U" shaped cross-section.

A method of collecting and transferring material using the apparatus 100 shown in fig. 1-3 is described below, the method comprising the steps of:

A) bringing the shutter 2 into the covering position and the box 1 into a horizontal or substantially horizontal position, so that the top 13 of the box is facing the target material and the sieve plate 3 is moved to the open position, i.e. the device 100 as a whole is in a condition suitable for collecting the material;

B) passing material through the through holes 31 of the screen 3 and the apertures 14 in the top 13 of the box 1 via the shovels 4 into the interior space of the box;

C) placing the box 1 in a vertical or substantially vertical position with the top 13 of the box facing directly or obliquely upwards and the screen 3 moved to the closed position while the shutter 2 remains in the covering position, i.e. the apparatus 100 as a whole is in a condition suitable for conveying material;

D) transferring the apparatus 100 to a discharge location;

E) placing the box 1 in a vertical or substantially vertical position such that the top 13 of the box is directed directly or obliquely downwards, the shutter 2 is moved to the deployed position and the sieve plate 3 is moved to the open position, i.e. the device 100 as a whole is in a condition suitable for discharging material; and

F) material is discharged from the interior space of the box through the outlet 17 and through the aligned through holes 31 of the screen deck 3 and the aperture 14 in the top 13 of the box 1.

According to the embodiment shown in fig. 1 to 3, in step a), the shutter 2 may be turned to the covering position by controlling the direction of the box 1 by operating the handle 5; furthermore, thanks to the inclined arrangement of the roof 13, the screen 3 slides automatically by means of its own weight to the open position along the guide slots 15 and along the surface of the roof 13, with the box 1 placed in a horizontal or substantially horizontal position. The open position may be defined by blade 4.

In steps B), C) and D), the shutter 2 can abut against the upper half of the surface of the top 13 (see fig. 1), automatically remaining in the covering position by virtue of its own weight and the inclined top 13.

In step C) the screen panel 3 slides by means of its own weight along the guide slots 15 and against the surface of the roof 13 to the closed position. The closed position may be defined by a stop portion 16 (i.e., the side of the shutter 2 connected to the top 13 in this embodiment), as shown in fig. 2.

In step E) the screen plate 3 is slid again by means of its own weight along the guide slots 15 and along the surface of the roof 13 to the open position. Likewise, the open position may be defined by blade 4. At the same time, the shutter 2 is turned over by its own weight into a state in which the free side (i.e., the side opposite to the side connected to the top 13) hangs down, resulting in the outlet 17 being exposed. So that material can be discharged from the outlet 17 and from the aligned through-holes 31 and apertures 14.

In the preferred embodiment, the user need only grip the handle 5 at all times and control the orientation and operation of the housing 1, the screen 2 and the screen 3 by means of the handle, avoiding the user's hands or other body parts from contacting any of the housing 1, the screen 2 and the screen 3.

The material of the device 100 may be determined as desired, and may be made of, for example, plastic, metal, or a combination thereof.

Although the present invention has been described with reference to the preferred embodiments, it is not limited thereto. Various changes and modifications within the spirit and scope of the present invention may be made by those skilled in the art without departing from the spirit and scope of the present invention, and therefore the scope of the present invention should be determined by that defined in the appended claims.
