Description

DESCRIPTION BUCKET FOR UNLOADING EQUIPMENT, FOR EASILY DISCHARGING MATERIALS 5 Technical Field The present invention relates, in general, to buckets for unloading equipment and, more particularly, to a bucket for unloading equipment capable of easily unloading materials 10 which is configured such that residual materials can be easily discharged out of the bucket, thus markedly enhancing the efficiency of unloading work. Background Art 15 Generally, buckets for unloading equipment which are used in power plants or steel mills function to scoop up materials and transport them before unloading them. A representative conventional technique pertaining to the present invention was proposed in Japanese Utility Model 20 Unexamined Publication No. Hei. 04-034216 (date: Mar. 23, 1992). In the above conventional technique, when a rotating arm makes contact with a fixed cam installed at a predetermined position on a potion of the unloading equipment, an opening 25 and closing member provided on a bottom surface of a bucket 1 opens to discharge residual materials out of the bucket. However, there is a structural limit in which the fixed cam is necessarily required to operate the opening and closing member. 5 That is, if the fixed cam is damaged or deformed, the rotating arm may not make contact with the fixed cam. In this case, the opening and closing member is not operated. Ultimately, residual materials cannot be discharged out of the bucket. 10 Furthermore, the conventional technique has a complex structure and thus frequently malfunctions. Consequently, there is a problem of low operating efficiency. Disclosure 15 Technical Problem Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a bucket for unloading equipment capable of easily discharging materials 20 which is configured such that when the bucket is moved upwards, a material discharging member is seated on a bottom surface of the bucket by its own weight so that the bucket can scoop up materials, and when the bucket is turned upside down, the material discharging member moves downwards due to its own 25 weight, thus smoothly and reliably discharging residual 2 materials out of the bucket. Another object of the present invention is to provide a bucket for unloading equipment capable of easily discharging materials which is provided with a weight and a spring so that 5 the material discharging member can be rapidly moved upwards or downwards depending on the orientation of the bucket, whereby residual materials can be more effectively discharged out of the bucket. A further object of the present invention is to provide a 10 bucket capable of easily discharging materials for unloading equipment in which a low-friction plate is installed to prevent materials from easily adhering to the surface of the bucket, thus minimizing adhesion of materials. 15 Technical Solution In order to accomplish the above objects, the present invention provides a bucket for unloading equipment capable of easily discharging materials, including: a material discharging member (110) seated, by a weight thereof, on a 20 bottom surface (11) of the bucket (10) and configured such that when the bucket (10) is turned upside down, the material discharging member (110) moves downwards due to the weight thereof and pushes and discharges residual materials out of the bucket (10); a plurality of moving shafts (120) coupled to 25 a lower surface of the material discharging member (110), the 3 moving shaft (120) passing through the bottom surface (11) so as to be vertically movable with respect to the bottom surface (11); and a support (130) coupled to lower ends of the moving shafts (120) and configured such that when the bucket (10) is 5 turned upside down, the support (130) that has been located at a lowermost position by a weight thereof moves downwards, comes into contact with the bottom surface (11) of the bucket (10), and thus supports the material discharging member (110). Furthermore, stoppers (11a) may be provided under the 10 bottom surface (11), each of the stoppers (11a) having a predetermined height. Each of the stoppers (11a) may have a receiving space (11b), and a spring (11c) may be disposed in the receiving space (11b), the spring (11c) being provided around a 15 circumferential outer surface of the corresponding moving shaft (120) and brought into contact with the material discharging member (110). In addition, a plurality of discharge holes (11d) may be formed in the bottom surface (11). 20 Furthermore, low-friction plates (111) and (12a) may be respectively provided on an upper surface of the material discharging member (110) and a side surface (12) of the bucket (10). An inclined guide (12b) may be provided on an upper end 25 of the low-friction plate (12a) . The inclined guide (12b) may 4 be inclined in a predetermined direction. Furthermore, a weight (131) may be installed on a portion of the support (130). 5 Advantageous Effects In a bucket for unloading equipment capable of easily discharging materials according to the present invention, a material discharging member smoothly moves upwards or downwards depending on the orientation of the bucket, thus 10 reliably discharging residual materials out of the bucket. Particularly, the material discharging member can move upwards or downwards by means of its own weight and discharge residual materials out of the bucket. Furthermore, the present invention has a simple structure 15 so that the operating efficiency can be improved.

Fig. 1 is a front view showing a bucket for unloading 20 equipment capable of easily discharging materials for according to an embodiment of the present invention. Fig. 2 is a front view showing a bucket for unloading equipment capable of easily discharging materials according to another embodiment of the present invention. Fig. 3 is a view 25 illustrating the operation of the bucket according to the 6 present invention. Fig. 4 is a view illustrating the installation of the bucket according to the present invention. The bucket 10 according to the present invention includes: a material discharging member 110 which is placed on 5 a bottom surface 11 of the bucket 10 by its own weight and configured such that when the bucket 10 is turned upside down, the material discharging member 110 moves downwards due to its own weight and pushes and discharges residual materials out of the bucket 10; a plurality of moving shafts 120 which are 10 coupled to a lower surface of the material discharging member 110 and pass through the bottom surface 11 so as to be vertically movable with respect to the bottom surface 11; and a support 130 which is coupled to lower ends of the moving shafts 120 and configured such that when the bucket 10 is 15 turned upside down, the support 130 that has been located at a lowermost position due to its own weight moves downwards, comes into contact with the bottom surface 11 of the bucket 10, and thus supports the material discharging member 110. When the bucket 10 moves upwards, the material 20 discharging member 110 is maintained, by its own weight, on the bottom surface 11 of the bucket 10 so that materials can be put into the bucket 10. Reversely, when the bucket 10 is turned upside down, the material discharging member 110 is moved downwards by its own weight, thus pushing residual 25 materials and discharging them out of the bucket 10. 7 Particularly, the material discharging member 110 has a large plate shape to cover the entirety of the bottom surface 11 of the bucket 10 and evenly push materials stored in the bucket 10 when discharging them out of the bucket 10. 5 Made of plastic-based high-strength low-friction material, a low-friction plate 111 may be provided on an upper surface of the material discharging member 110 so as to prevent materials from easily adhering to the material discharging member 110. 10 The moving shafts 120 function to guide the material discharging member 110 so that the material discharging member 110 can smoothly move upwards or downwards. When the bucket 10 is turned upside down and thus the material discharging member 110 is moved downwards, the 15 support 130 comes into contact with the bottom surface of the bucket 10 and supports the material discharging member 110, thus preventing the material discharging member 110 from be removed from the bucket 10. A weight 131 may be provided at a predetermined position 20 on the support 130. The weight 131 causes the support 130 to be easily placed on the bottom surface 11 of the bucket 10 when the bucket 10 is moved upwards. Also, when the bucket 10 is turned upside down, the weight 131 causes the support 130 to be rapidly moved downwards, whereby residual materials can 25 be easily discharged out of the bucket 10. 8 Preferably, the weight 131 comprises a plurality of weights to make it possible for a worker to adjust the weight of the weight 131. Stoppers 11a, each of which has a predetermined height, 5 are provided under the bottom surface 11. The reason for this is that when the bucket 10 is turned upside down, the stoppers 11a make contact with the support 130 and prevent the support 130 from coming into direct contact with the bottom surface 11 of the bucket 10, whereby space is defined between the support 10 130 and the stopper 11a so that materials can pass between the support 130 and the bottom surface 11 of the bucket 10 without adhering thereto. As shown in Fig. 2, each stopper 11a has a receiving space lb. Provided around the circumferential outer surface 15 of each moving shaft 130, a spring lc is disposed in the corresponding receiving space lb in such a way that the spring lc makes contact with the material discharging member 110. For this, when the bucket 10 is turned upside down, the support 130 can be rapidly moved downwards by the elastic 20 force of the springs lc so that residual materials can be more easily discharged out of the bucket 10. Furthermore, a plurality of discharge holes lid are formed in the bottom surface 11 so that even if materials are placed on the bottom surface 11, they can be smoothly 25 discharged out of the bucket 10 through the discharge holes 9 lid. Thereby, the material discharging member 110 can be fundamentally prevented from malfunctioning while moving upwards and downwards. Particularly, a low-friction plate 12a is installed on 5 each side surface 12 of the bucket 10. An inclined guide 12b, which is inclined on an upper end thereof in a predetermined direction, is provided on an upper end of the each low friction plate 12a. The low-friction plate 12a is made of plastic-based high 10 strength low-friction material to prevent materials from adhering to the low-friction plate 12a. While the bucket 10 scoops up materials, the inclined guide 12b, when making contact with materials, causes the materials to smoothly move downwards along the inclined guide 15 12b, thus minimizing interference with the low-friction plate 12a, thereby preventing a gap from occurring between the low friction plate 12a and the side surface of the bucket. In the present invention having the above-mentioned construction, as shown in Fig. 4, while the bucket 10 scoops 20 up materials by means of the operation of the unloading equipment A, the material discharging member 110 is seated, by its own weight, on the bottom surface 11 of the bucket 10. Reversely, when the bucket 10 is turned upside down, the material discharging member 110 is moved downwards by its own 25 weight, thus pushing downwards materials remaining in the 10 bucket 10 and reliably discharging them out of the bucket 10. Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, 5 additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. 11
