[0040] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0041] Based on the current technology, the material conveying device is equipped with a hopper to dump the material. The height of the hopper is high, and the material is easy to splash. The present application provides a material conveying device, please see Figure 1 , which comprises a base 100, a turnover frame 200 and a first driving unit 300. The base 100 is adapted to move between a receiving station 700 and a dumping station (not marked in the figure). The receiving station 700 can be seen in Figure 2 , and the dumping station is not marked in the figure. Figure 2 In the receiving station 700, the receiving station 700 comprises a first station 710 and a second station 720, of course, it can also have only one receiving station 700. In combination with Figure 1 , the base 100 is formed with a discharge port 110, the turnover frame 200 is installed on the base 100, the turnover frame 200 is adapted to receive the hopper 400 from the receiving station 700 and drive the hopper 400 to move to the dumping station. The first driving unit 300 is installed on the base 100 and is adapted to drive the turnover frame 200 to rotate relative to the base 100 to switch between an initial position and a dumping position. In the dumping position, the discharge port 410 of the hopper 400 corresponds to the discharge port 110.

[0042] According to the embodiment of the present application, since the turnover frame 200 drives the hopper 400 to rotate, the position of the material pouring side of the hopper 400 is lowered in the process of rotation, so that the material pouring opening 410 is close to the material pouring opening 110, thereby preventing the material from splashing caused by high-position material pouring. Moreover, since the material pouring opening 410 is close to the material pouring opening 110, the noise in the process of material pouring can be reduced, the noise pollution can be reduced, and the environment for the workers can be improved.

[0043] Figure 2 In the embodiment, along the width direction of the material pouring opening 110, the left side edge of the material pouring opening 410 is located within the left side edge of the material pouring opening 110 (i.e., located to the right of the left side edge of the material pouring opening 110), so as to ensure that the material will not scatter outside the material pouring opening 110 in the process of material pouring. In addition, when the turnover frame 200 rotates to the material pouring position, at this time, i.e., the hopper 400 rotates to the limit angle, corresponding to the limit angle, the left side edge of the hopper 400 rotates to the vicinity of the right side edge of the material pouring opening 110, and the left side edge of the hopper 400 is located within the right side edge of the material pouring opening 110 (i.e., located to the left of the right side edge of the material pouring opening 110).

[0044] According to the embodiment of the present application, the turnover frame 200 is in a circular ring shape, on the basis of which, after receiving the hopper 400, the material pouring opening 410 of the hopper 400 can correspond to the upper part of the turnover frame 200, so that after the turnover frame 200 rotates through a certain angle, the material pouring opening 410 rotates to a lower height. Of course, after the hopper 400 enters the turnover frame 200, the hopper 400 can also be arranged at a middle position or other position of the turnover frame 200. The turnover frame 200 can be driven by the cooperation of the first chain 320 and the sprocket 310, or the turnover frame 200 can also be driven by other driving mechanisms, as long as the turnover frame 200 can rotate around its own center axis.

[0045] When the first driving unit 300 includes the sprocket 310, and the turnover frame 200 is driven by the first chain 320 and the sprocket 310, please refer to Figure 3 and Figure 4 The first chain 320 is installed on the outer periphery of the turnover frame 200, and the sprocket 310 is installed on the base 100, and the turnover frame 200 is driven to rotate by the cooperation between the sprocket 310 and the first chain 320. In combination with Figure 3 and Figure 4It is also found that a plurality of support wheels 130 are installed on the base 100, and the turnover frame 200 is installed on the base 100 through the support wheels 130. Among them, the number of support wheels 130 can be multiple, for example, the support wheels 130 are four, and the turnover frame 200 is installed above the four support wheels 130. The support wheels 130 here can adopt rolling wheels to reduce the friction between the turnover frame 200 and the base 100. Of course, it is also not excluded that the support wheels 130 are sliding wheels. At this time, in order to reduce the friction between the turnover frame 200 and the sliding wheels, a plurality of rolling wheels can also be arranged on the outer periphery of the turnover frame 200. Of course, in addition to supporting the turnover frame 200 by using the support wheels 130, a set of support columns (not shown in the figure) can also be arranged on the base 100, and the central shaft of the turnover frame 200 is installed on the support column, and then the turnover frame 200 rotates relative to the support column. Among them, a rotating shaft can be arranged between the set of support columns, and the turnover frame 200 is fixed to the rotating shaft; or the turnover frame 200 is installed between two support columns through a plurality of bearing seats.

[0046] Please refer to Figure 5 , the outer periphery of the turnover frame 200 is provided with an annular groove 227, in combination with Figure 4 , the first chain 320 is installed through the annular groove 227, which can prevent the loosening of the first chain 320. In addition, the annular groove 227 and the support wheel 130 can also be matched to ensure the reliability of the installation of the turnover frame 200 on the support wheel 130. Here, the annular groove 227 used to install the first chain 320 and the annular groove 227 used to cooperate with the support wheel 130 can be the same annular groove or different annular grooves.

[0047] The positional relationship of the turnover frame 200, the first chain 320, the support wheel 130 and the sprocket 310 can be seen from Figure 6 , the first chain 320 is arranged around the support wheel 130 and the sprocket 310 and is fixed to the annular groove 227. Among them, the first chain 320 can adopt double-row chain to enhance its structural strength and improve its driving effect. And the first chain 320 arranged around the sprocket 310 can form Figure 6The distribution of the chain in the first chain 320 further ensures that the distribution of the first chain 320 is reasonable, ensures the reliability of the installation, and avoids the first chain 320 from falling off the sprocket 310. In this case, the support wheel 130 and the first chain 320 are matched with the same annular groove 227, and the position of the support wheel 130 and the first chain 320 does not interfere, thereby ensuring the compactness of the structure of the material conveying device. Moreover, since the first chain 320 is fixed at both ends of the annular groove 227, the self-rotation angle of the turnover frame 200 is preferably not more than 180°, for example, from the initial position to the material pouring position, the self-rotation angle of the turnover frame 200 is 120-170°, and specifically can be 165°. In this case, it can be ensured that the hopper 400 is fully turned over, and the material in the hopper 400 is not completely poured. At the same time, the first chain 320 fixed at both ends of the turnover frame 200 will not move to the position corresponding to the support wheel 130. Of course, in the case that the first chain 320 and the support wheel 130 are not arranged on the same circumference, the first chain 320 can also be in the form of a complete ring and be fixed to the outer periphery of the turnover frame 200. At this time, the rotation angle of the turnover frame 200 is not limited, and it can rotate at any angle.

[0048] According to the embodiments of the present application, in combination with Figure 1 and Figure 6 , the sprocket 310 includes a driving sprocket 311 and a driven sprocket 312 arranged on opposite sides of the base 100. The driven sprocket 312 is arranged on the left side of the figure and is arranged adjacent to the support wheel 130 on the left side. In Figure 6 , the driven sprocket 312 is shielded by a cover plate and is not identified. The cover plate here can play a protective role. Similarly, although Figure 6 is not shown, it can be understood that a protective cover plate is also arranged outside the driving sprocket 311. The driving sprocket 311 and the driven sprocket 312 can ensure the effectiveness of driving the turnover frame 200, and avoid stress concentration on the first chain 320 and the sprocket 310, and avoid fatigue damage.

[0049] Please refer again to Figure 5The top of the turnover frame 200 is provided with a buffer pad 226, which is used to flexibly contact the hopper 400 during the switching of the turnover frame 200 from the initial position to the dumping position. Specifically, in order to ensure that the hopper 400 can enter the turnover frame 200, it is obvious that there needs to be a gap between the top of the hopper 400 and the top of the turnover frame 200. However, during the dumping of the material, the above gap will cause the hopper 400 to shake, thereby damaging the hopper 400 or the turnover frame 200, and there will be a large impact noise. The embodiment of the present application sets the buffer pad 226 on the top of the turnover frame 200, so that during the turnover process, the hopper 400 will not directly impact the turnover frame 200, but will flexibly contact the turnover frame 200 through the buffer pad 226, which can reduce the operating noise on the basis of protecting the hopper 400 and the turnover frame 200. Figure 5 In the turnover frame 200, a plurality of crossbeams 224 are arranged on the top of the turnover frame 200, the crossbeams 224 avoid the dumping side of the hopper 400, and the buffer pad 226 is fixed to the crossbeams 224. One of the crossbeams 224 is arranged at the middle position of the turnover frame 200, and the other crossbeam 224 is arranged at the right side position of the turnover frame 200. The above two crossbeams 224 can better avoid the dumping side of the hopper 400, so as to ensure that the crossbeams 224 will not block the material during the dumping of the material. Figure 5 In the turnover frame 200, a plurality of crossbeams 224 are arranged on the top of the turnover frame 200, the crossbeams 224 avoid the dumping side of the hopper 400, and the buffer pad 226 is fixed to the crossbeams 224. One of the crossbeams 224 is arranged at the middle position of the turnover frame 200, and the other crossbeam 224 is arranged at the right side position of the turnover frame 200. The above two crossbeams 224 can better avoid the dumping side of the hopper 400, so as to ensure that the crossbeams 224 will not block the material during the dumping of the material.

[0050] Figure 5 In the turnover frame 200, a plurality of crossbeams 224 are arranged on the top of the turnover frame 200, the crossbeams 224 avoid the dumping side of the hopper 400, and the buffer pad 226 is fixed to the crossbeams 224. One of the crossbeams 224 is arranged at the middle position of the turnover frame 200, and the other crossbeam 224 is arranged at the right side position of the turnover frame 200. The above two crossbeams 224 can better avoid the dumping side of the hopper 400, so as to ensure that the crossbeams 224 will not block the material during the dumping of the material.

[0051] Please further refer to Figure 6 The base 100 is provided with a fixed rod 140, and the material conveying device further comprises a first drag chain 500, one end of the first drag chain 500 is fixed to the fixed rod 140, the other end of the first drag chain 500 is fixed to the turnover frame 200, and the first drag chain 500 is provided with a first cable, which is used to connect the electrical elements on the base 100 and the electrical elements on the turnover frame 200. Figure 6The fixed rod 140 is arranged corresponding to the rotation center of the turnover frame 200, of course, the fixed rod 140 can also be arranged at other positions. And the number, distribution position and height of the fixed rod 140 are not limited by the present situation of the drawings, the fixed rod 140 is arranged based on the distribution requirement of the first cable. On the basis of arranging the fixed rod 140, the turnover frame 200 can be rotatably arranged on the fixed rod 140, at this time, the fixed rod 140 is equivalent to the support column mentioned above. The electrical element on the base 100 can be but is not limited to a motor and a power supply and the like.

[0052] With reference to Figure 1 and Figure 2 , the material conveying device comprises a track 600, the base 100 is arranged on the track 600, and then the base 100 is switched between the receiving station 700 and the pouring station along the track 600. The receiving station 700 can comprise a first station 710 and a second station 720 located at both ends of the track 600. Of course, the receiving station 700 can also be one and arranged corresponding to the track 600, or the number of the receiving station 700 can also be more.

[0053] According to the embodiment of the present application, with reference to Figure 1 and Figure 5 , the turnover frame 200 can comprise a support body 220 and a receiving support 210, and the receiving support 210 is arranged on the support body 220. The support body 220 comprises an annular support 221 and a bottom support 222, the annular support 221 is adapted to rotate relative to the base 100, and the bottom support 222 is adapted to fix the receiving support 210. In order to ensure the structural strength of the turnover frame 200, the annular support 221 is provided with a plurality of reinforcing rods 223. The receiving support 210 can be arranged separately relative to the support body 220, and then the necessary related components can be conveniently arranged on the receiving support 210.

[0054] According to the embodiment of the present application, with reference to Figure 1 and Figure 2The turnover frame 200 is provided with a second driving unit 250, and the second driving unit 250 is suitable for driving the hopper 400 to transfer between the receiving station 700 and the turnover frame 200. The second driving unit 250 can include a second chain provided on the receiving support 210, and the second chain drives the hopper 400 to move, so that the hopper 400 is transferred between the receiving station 700 and the receiving support 210. In addition, the receiving station 700 can also be provided with a chain mechanism 730 corresponding to the receiving station 700. When the hopper 400 is placed on the chain mechanism 730 of the receiving station 700, the hopper 400 can be moved to the second chain along with the chain mechanism 730. The second chain can better receive the hopper 400 at this time, and the hopper 400 can be moved to the turnover frame 200. Conversely, when the hopper 400 is moved from the turnover frame 200 to the receiving station 700, the second chain drives the hopper 400 to move towards the receiving station 700, and the chain mechanism 730 of the receiving station 700 also moves to receive the hopper 400, and further drives the hopper 400 to move away from the turnover frame 200 and stably fall on the receiving station 700. Obviously, during the transfer of the hopper 400, the receiving station 700 and the receiving support 210 on the turnover frame 200 need to be connected.

[0055] According to the embodiment of the present application, when the hopper 400 is transferred between the receiving station 700 and the turnover frame 200, in order to position the hopper 400, the turnover frame 200 can be provided with a limiting part. The limiting part is arranged in front of the movement direction of the hopper 400 to stop the hopper 400. When the receiving station 700 includes the first station 710 and the second station 720, the limiting part is arranged on the side of the turnover frame 200 opposite to the side of the turnover frame 200 where the hopper 400 is poured, in order to bidirectionally receive the hopper 400. Specifically, the limiting part can be arranged on the receiving support 210 of the turnover frame 200. Figure 1 、 Figure 2 、 Figure 5As shown in FIG. 7, the limiting component includes a first limiting member 230 and a second limiting member 240. The first limiting member 230 is arranged on the side of the turnover frame 200 facing the first work station 710, and the second limiting member 240 is arranged on the side of the turnover frame 200 facing the second work station 720. Both the first limiting member 230 and the second limiting member 240 have a horizontal position and a vertical position. When the first limiting member 230 is in the horizontal position, the hopper 400 is adapted to be transferred between the first work station 710 and the turnover frame 200, and when the second limiting member 240 is in the horizontal position, the hopper 400 is adapted to be transferred between the second work station 720 and the turnover frame 200. When the first limiting member 230 and the second limiting member 240 are in the vertical position, the hopper 400 is limited between the first limiting member 230 and the second limiting member 240. If the end of the track 600 is provided with only one receiving work station 700, then only the limiting member facing the receiving work station 700 needs to have the horizontal position, and the limiting member facing away from the receiving work station 700 does not need to have the horizontal position.

[0056] According to the embodiments of the present application, please refer to Figure 5 The first limiting member 230 and the second limiting member 240 can include a top limiting member, which is mounted on the annular support 221. In addition, referring to Figure 7 The first limiting member 230 and the second limiting member 240 both include a bottom limiting member, which can be mounted on the receiving support 210. Of course, the first limiting member 230 and the second limiting member 240 can also include only one of the top limiting member and the bottom limiting member. The number of the top limiting member and the bottom limiting member is not limited, as long as the position of the hopper 400 can be stopped and limited.

[0057] When the hopper 400 is transferred from the first work station 710 to the turnover frame 200, for the first limiting member 230, the first limiting member 230 can be controlled to switch from the horizontal position to the vertical position when the hopper 400 contacts the second limiting member 240. Similarly, when the hopper 400 is transferred from the second work station 720 to the turnover frame 200, for the second limiting member 240, the second limiting member 240 can be controlled to switch from the horizontal position to the vertical position when the hopper 400 contacts the first limiting member 230.

[0058] When the hopper 400 is transferred from the turnover frame 200 to the first work station 710, for the first limiting member 230, the first limiting member 230 can be controlled to switch from the vertical position to the horizontal position when the turnover frame 200 and the first work station 710 are docked. Similarly, when the hopper 400 is transferred from the turnover frame 200 to the second work station 720, for the second limiting member 240, the second limiting member 240 can be controlled to switch from the vertical position to the horizontal position when the turnover frame 200 and the second work station 720 are docked.

[0059] The first limiting member 230 and the second limiting member 240 can be pneumatic members, and can also be hydraulic driving members or motor driving members.

[0060] Please refer to Figure 8 The base 100 is provided with traveling wheels 150 and a third driving unit 900 connected with the traveling wheels 150. The traveling wheels 150 include traveling driving wheels 151 connected with the third driving unit 900, and the third driving unit 900 can be a traveling reduction motor. The traveling wheels 150 further include traveling driven wheels 152. The traveling wheels 150 are driven to rotate by the third driving unit 900, so as to ensure that the base 100 and the turnover frame 200 travel along the track 600. Of course, the driving mode of the base 100 is not limited by the example, for example, the base 100 can also be driven by a plurality of motors to drive a plurality of pairs of traveling driving wheels 151.

[0061] In addition, the driving motor of the first driving unit 300, i.e., the turnover reduction motor 330, can also be arranged on the base 100. Specifically, the turnover reduction motor 330 drives the sprocket 310 on the base 100 to rotate, and the sprocket 310 drives the turnover frame 200 to rotate through the first chain 320. Of course, the positions of the traveling reduction motor and the turnover reduction motor 330 are not limited by the drawings, as long as they can respectively drive the base 100 to travel and drive the turnover frame 200 to rotate.

[0062] In addition, Figure 8 In the embodiment, the track 600 is provided with a second drag chain 800, and the second drag chain 800 is provided with a second cable.

[0071] After the hopper 400 completely enters the receiving support 210 of the turnover frame 200, the second limit member 240 is automatically reset, the hopper 400 walks to be close to the second limit member 240, and the second chain stops moving.

[0072] The material conveying device automatically walks to the designated hopper receiving position of the second work station 720, that is, the material pouring work station, through the track 600 on the ground. The turnover reduction motor 330 drives the sprocket 310 to rotate, so as to drive the turnover frame 200 to rotate to the material pouring position through the second chain. In this process, the turnover reduction motor 330 drives the turnover frame 200 to rotate counterclockwise by about 165°, the material is poured out through the guide plate 120 into the material pouring port 110, and enters the next process.

[0073] The turnover frame 200 resets, the material conveying device walks to the second station 720, the second limiting piece 240 is laid flat, the second chain and the chain mechanism 730 on the second station 720 are both started, the empty hopper 400 is transferred from the second chain to the second station 720, the second limiting piece 240 resets, and the complete flow of the material transfer of the second station 720 ends.
