[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Based on the problem that in the process of dumping materials with a hopper in the current technology, the hopper is at a high height and the materials are easily splashed. Figure 1 , including a base 100, a turning frame 200 and a first driving unit 300. The base 100 is suitable for moving between a material receiving station 700 and a material unloading station (not shown in the figure), wherein the material receiving station 700 can refer to Figure 2 , the unloading station is not marked in the figure. Figure 2 In the embodiment, the material receiving station 700 includes a first station 710 and a second station 720. Of course, there may be only one material receiving station 700. Figure 1 The base 100 is formed with a pouring port 110, and the turning frame 200 is installed on the base 100. The turning frame 200 is suitable for receiving the hopper 400 from the receiving station 700 and driving the hopper 400 to move to the pouring station. The first driving unit 300 is installed on the base 100, and is suitable for driving the turning frame 200 to rotate relative to the base 100 to switch between the initial position and the pouring position. In the pouring position, the discharge port 410 of the hopper 400 corresponds to the pouring port 110.

[0027] According to the embodiment of the present application, since the tipping frame 200 drives the hopper 400 to rotate, the position of the dumping side of the hopper 400 is lowered during the rotation process, so that the discharge port 410 is close to the dumping port 110, thereby preventing the material from splashing due to high-position dumping. In addition, since the discharge port 410 is close to the dumping port 110, the noise during the material dumping process can be reduced, noise pollution can be reduced, and the environment where the staff are located can be improved.

[0028] Figure 2In the embodiment, along the width direction of the pouring port 110, the left edge of the discharge port 410 is located inside the left edge of the pouring port 110 (that is, located to the right of the left edge of the pouring port 110) to ensure that the material will not be scattered outside the pouring port 110 during the pouring process. In addition, when the overturning frame 200 rotates to the pouring position, that is, the hopper 400 rotates to the limit angle, corresponding to the limit angle, the left edge of the hopper 400 rotates to the vicinity of the right edge of the pouring port 110, and the left edge of the hopper 400 is located inside the right edge of the pouring port 110 (that is, located to the left of the right edge of the pouring port 110).

[0029] According to the embodiment of the present application, the turning frame 200 is in a circular ring shape. On this basis, after receiving the hopper 400, the discharge port 410 of the hopper 400 can correspond to the upper part of the turning frame 200, so that after the turning frame 200 rotates to a certain angle, the discharge port 410 rotates to a lower height. Of course, after the hopper 400 enters the turning frame 200, it can also be set in the middle position or other positions of the turning frame 200. Among them, the turning frame 200 can be driven by the cooperation of the first chain 320 and the sprocket 310, or the turning frame 200 can also be driven by other driving mechanisms, as long as it is ensured that the turning frame 200 can rotate around its own central axis.

[0030] When the first driving unit 300 includes a sprocket 310, and the flip frame 200 is driven by the first chain 320 and the sprocket 310, see Figure 3 and Figure 4 , the first chain 320 is installed on the outer periphery of the turning frame 200, the sprocket 310 is installed on the base 100, and the turning frame 200 is driven to rotate by the cooperation between the sprocket 310 and the first chain 320. Figure 3 and Figure 4It is also found that a plurality of support wheels 130 are installed on the base 100, and the flip frame 200 is installed on the base 100 through the support wheels 130. The number of the support wheels 130 can be multiple, for example, there are four support wheels 130, and the flip frame 200 is installed above the four support wheels 130. The support wheels 130 here can be rolling wheels to reduce the friction between the flip frame 200 and the base 100. Of course, the support wheels 130 are sliding wheels. In this case, in order to reduce the friction between the flip frame 200 and the sliding wheel, a plurality of rollers can also be arranged on the periphery of the flip frame 200. Of course, in addition to using the support wheels 130 to support the flip frame 200, a group of support columns (not shown in the figure) can also be arranged on the base 100, and the central axis of the flip frame 200 can be installed on the support columns, so that the flip frame 200 rotates relative to the support columns. A rotating shaft may be provided between a group of supporting columns, and the turning frame 200 may be fixed to the rotating shaft; or the turning frame 200 may be installed between two supporting columns via a plurality of bearing seats.

[0031] See also Figure 5 The outer periphery of the flip frame 200 is provided with an annular groove 227, combined with Figure 4 , the first chain 320 can be installed through the annular groove 227 to prevent the first chain 320 from loosening. In addition, the annular groove 227 can also cooperate with the support wheel 130 to ensure the reliability of the installation of the flip frame 200 on the support wheel 130. Here, the annular groove 227 for installing the first chain 320 and the annular groove 227 for cooperating with the support wheel 130 can be the same annular groove or different annular grooves.

[0032] The positional relationship between the turning frame 200, the first chain 320, the support wheel 130 and the sprocket 310 can be seen in Figure 6 The first chain 320 is wound around the support wheel 130 and the sprocket 310 and the end is fixed to the annular groove 227. The first chain 320 can be a double-row chain to enhance its structural strength and improve its driving effect. The first chain 320 wound around the sprocket 310 can form Figure 6The distribution mode of the chain in the sprocket 310 further ensures that the distribution of the first chain 320 is reasonable, ensures the reliability of its installation, and prevents the first chain 320 from falling off the sprocket 310. In this case, the support wheel 130 and the first chain 320 are both matched with the same annular groove 227, and the positions of the support wheel 130 and the first chain 320 do not interfere with each other, thereby ensuring the compactness of the material conveying device structure. In addition, since the first chain 320 is fixed at both ends in the annular groove 227, the rotation angle of the overturning frame 200 is preferably not more than 180°. For example, from the initial position to the dumping position, the rotation angle of the overturning frame 200 is 120-170°, specifically 165°. In this case, the hopper 400 can be fully overturned to avoid incomplete dumping of the hopper 400 materials. At the same time, the first chain 320 fixed at both ends of the overturning frame 200 will not move to the position corresponding to the support wheel 130. Of course, when the first chain 320 and the supporting wheel 130 are not arranged on the same circumference, the first chain 320 can also be in a complete ring shape and fixed to the outer circumference of the turning frame 200. At this time, the rotation angle of the turning frame 200 is not limited and it can rotate at any angle.

[0033] According to the embodiments of the present application, Figure 1 and Figure 6 The sprocket 310 includes a driving sprocket 311 and a driven sprocket 312 disposed on opposite sides of the base 100. The driven sprocket 312 is disposed on the left side of the figure and is adjacent to the support wheel 130 on the left side. Figure 6 The driven sprocket 312 is blocked by the cover plate and is not marked. The cover plate here can play a protective role. Figure 6 Although not shown, it is understood that a protective cover plate is also provided outside the driving sprocket 311. The driving sprocket 311 and the driven sprocket 312 can ensure the effectiveness of driving the overturning frame 200, and avoid stress concentration on the first chain 320 and the sprocket 310, thereby avoiding fatigue damage.

[0034] Please see again Figure 5, a buffer pad 226 is provided on the top of the turning frame 200, and the buffer pad 226 is used to flexibly contact the hopper 400 during the process of the turning frame 200 switching from the initial position to the material dumping position. Specifically, in order to ensure that the hopper 400 can enter the turning frame 200, it is obvious that there needs to be a gap between the top of the hopper 400 and the top of the turning frame 200. In the process of dumping the material, the above gap will cause the hopper 400 to shake, thereby damaging the hopper 400 or the turning frame 200, and there will be a large impact noise. In the embodiment of the present application, a buffer pad 226 is provided on the top of the turning frame 200, so that during the turning process, the hopper 400 will not directly hit the turning frame 200, but will flexibly contact the turning frame 200 through the buffer pad 226. On the basis of protecting the hopper 400 and the turning frame 200, the operating noise can be reduced. Figure 5 In the embodiment, a plurality of cross beams 224 are arranged on the top of the turning frame 200, and the cross beams 224 avoid the material pouring side of the hopper 400, and the buffer pads 226 are fixed to the cross beams 224. One cross beam 224 is arranged in the middle of the turning frame 200, and another cross beam 224 is arranged on the right side of the turning frame 200. The above two cross beams 224 can avoid the material pouring side of the hopper 400, ensuring that the cross beams 224 will not block the material during the material pouring process. Figure 5 There are two cross beams 224, and two buffer pads 226 are respectively arranged on the two cross beams 224. It can be understood that the number and distribution of the cross beams 224, and the distribution and number of the buffer pads 226 on the cross beams 224 are not limited by the drawings.

[0035] Figure 5 In the embodiment, the crossbeam 224 extends out with a mount 225, and the buffer pad 226 is fixed on the mount 225. Furthermore, based on different types of hoppers 400, the number of the mount 225 and the buffer pad 226 can also be adjusted. The mount 225 can also be set to a liftable structure, and based on different types of hoppers 400, the extension height of the mount 225 can also be adjusted to ensure that the buffer pad 226 on the mount 225 can fully contact the upper surface of the hopper 400. The buffer pad 226 here can be a flat plate or a rectangular block structure, and can also be any structure that can be compatible with the upper surface of the hopper 400 based on the different structures of the upper surface of the hopper 400.

[0036] Please see further Figure 6 The base 100 is provided with a fixed rod 140, and the material conveying device also includes a first drag chain 500, one end of the first drag chain 500 is fixed to the fixed rod 140, and the other end of the first drag chain 500 is fixed to the turning frame 200, and the first drag chain 500 is provided with a first cable, and the first cable is used to connect the electrical components on the base 100 and the electrical components on the turning frame 200. Figure 6In the figure, the fixing rod 140 is arranged corresponding to the rotation center of the flip frame 200. Of course, the fixing rod 140 can also be arranged at other positions. In addition, the number, distribution position and height of the fixing rods 140 are not limited to the current situation of the attached figure, and the fixing rods 140 are arranged specifically based on the distribution requirements of the first cable. On the basis of the setting of the fixing rod 140, the flip frame 200 can be rotatably mounted on the fixing rod 140. At this time, the fixing rod 140 is equivalent to the support column mentioned above. Among them, the electrical components on the base 100 can be but not limited to motors and power supplies.

[0037] refer to Figure 1 and Figure 2 The material conveying device includes a track 600, and the base 100 is installed on the track 600, and then the base 100 switches between the material receiving station 700 and the material unloading station along the track 600. Among them, the material receiving station 700 may include a first station 710 and a second station 720 located at both ends of the track 600. Of course, the material receiving station 700 can also be one and corresponding to the track 600, or, it is not excluded that the number of material receiving stations 700 is more.

[0038] According to the embodiments of this application, please refer to Figure 1 and Figure 5 The turning frame 200 may include a support body 220 and a material receiving support 210, and the material receiving support 210 is installed on the support body 220. The support body 220 includes an annular support 221 and a bottom support frame 222, the annular support 221 is suitable for rotating relative to the base 100, and the bottom support frame 222 is suitable for fixing the material receiving support 210. In order to ensure the structural strength of the turning frame 200, the annular support 221 is provided with a plurality of reinforcing rods 223. The material receiving support 210 can be separately provided relative to the support body 220, so that the necessary related components can be conveniently installed on the material receiving support 210.

[0039] According to the embodiments of the present application, Figure 1 and Figure 2The overturning frame 200 is equipped with a second driving unit 250, which is suitable for driving the hopper 400 to transfer between the receiving station 700 and the overturning frame 200. The second driving unit 250 may include a second chain provided on the receiving bracket 210, and the hopper 400 is driven to move by the second chain, so that the hopper 400 is transferred between the receiving station 700 and the receiving bracket 210. In addition, the receiving station 700 may also be provided with a chain mechanism 730. When the hopper 400 is placed on the chain mechanism 730 of the receiving station 700, the hopper 400 can move to the second chain along with the chain mechanism 730. The movement of the second chain at this time can better support the hopper 400 and enable the hopper 400 to move to the overturning frame 200. On the contrary, when the hopper 400 moves from the turning frame 200 to the receiving station 700, the second chain drives the hopper 400 to move toward the receiving station 700, and the chain mechanism 730 on the receiving station 700 also moves to receive the hopper 400, and drives the hopper 400 to further leave the turning frame 200 and stably land on the receiving station 700. Obviously, in the process of transferring the position of the hopper 400, the receiving station 700 and the receiving bracket 210 on the turning frame 200 need to be docked.

[0040] According to an embodiment of the present application, when transferring the hopper 400 between the material receiving station 700 and the turning frame 200, in order to position the hopper 400, the turning frame 200 may be provided with a limiting component, wherein the limiting component is provided in front of the moving direction of the hopper 400 to stop the hopper 400. When the material receiving station 700 includes a first station 710 and a second station 720, since the hopper 400 needs to be received in both directions, limiting components are provided on the material discharge side and the other side opposite to the material discharge side of the turning frame 200. Specifically, in combination with Figure 1 , Figure 2 , Figure 57 , the limiting component includes a first limiting member 230 and a second limiting member 240. The first limiting member 230 is disposed on the side of the flip frame 200 facing the first station 710, and the second limiting member 240 is disposed on the side of the flip frame 200 facing the second station 720. The first limiting member 230 and the second limiting member 240 both have a horizontal position and a vertical position. In the horizontal position of the first limiting member 230, the hopper 400 is suitable for transferring between the first station 710 and the flip frame 200. In the horizontal position of the second limiting member 240, the hopper 400 is suitable for transferring between the second station 720 and the flip frame 200. In the vertical position of the first limiting member 230 and the second limiting member 240, the hopper 400 is restricted between the first limiting member 230 and the second limiting member 240. If only one material receiving station 700 is provided at the end of the track 600, then only the limiting member facing the material receiving station 700 needs to have a flat position, and the limiting member facing away from the material receiving station 700 does not need to have a flat position.

[0041] According to the embodiments of this application, see Figure 5 , the first stopper 230 and the second stopper 240 may include a top stopper, and the top stopper is installed on the annular bracket 221. In addition, referring to Figure 7 The first stopper 230 and the second stopper 240 both include a bottom stopper, and the bottom stopper can be installed on the material receiving bracket 210. Of course, the first stopper 230 and the second stopper 240 can also include only one of the top stopper and the bottom stopper. And the number of the top stopper and the bottom stopper is not limited, as long as the position of the hopper 400 can be stopped and limited.

[0042] When the hopper 400 is transferred from the first station 710 to the overturning frame 200, the first stopper 230 can be controlled to switch from the horizontal position to the vertical position when the hopper 400 contacts the second stopper 240. Similarly, when the hopper 400 is transferred from the second station 720 to the overturning frame 200, the second stopper 240 can be controlled to switch from the horizontal position to the vertical position when the hopper 400 contacts the first stopper 230.

[0043] When the hopper 400 is transferred from the turning frame 200 to the first station 710, the first stopper 230 can be controlled to switch from the vertical position to the horizontal position when the turning frame 200 and the first station 710 are docked. Similarly, when the hopper 400 is transferred from the turning frame 200 to the second station 720, the second stopper 240 can be controlled to switch from the vertical position to the horizontal position when the turning frame 200 and the second station 720 are docked.

[0044] The first limiting member 230 and the second limiting member 240 may both be pneumatic members, and of course, hydraulic drive members or motor drive members may also be used.

[0045] See also Figure 8 The base 100 is provided with a walking wheel 150 and a third driving unit 900 connected to the walking wheel 150. The walking wheel 150 includes a walking driving wheel 151 connected to the third driving unit 900. The third driving unit 900 here can be a walking reduction motor, and the walking wheel 150 also includes a walking driven wheel 152. The walking wheel 150 is driven to rotate by the third driving unit 900 to ensure that the base 100 and the flip frame 200 walk along the track 600. Of course, the driving method of the base 100 is not limited to the examples given here. For example, the base 100 can also drive multiple pairs of walking driving wheels 151 through multiple motors.

[0046] In addition, the driving motor of the first driving unit 300, that is, the turning reduction motor 330, can also be arranged on the base 100. Specifically, the turning reduction motor 330 drives the sprocket 310 on the base 100 to rotate, and the sprocket 310 drives the turning frame 200 to rotate through the first chain 320. Of course, the setting positions of the travel reduction motor and the turning reduction motor 330 are not limited by the drawings, as long as they can drive the base 100 to travel and drive the turning frame 200 to rotate respectively.

[0047] also, 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, and the second cable is used to connect the power supply on the track 600 and the electrical components on the base 100. The second drag chain 800 can facilitate the base 100 to take power from the track 600.

[0048] In addition, from Figure 8 It can be seen that the base 100 is formed with an inclined material guide plate 120 corresponding to the material pouring port 110 , and the material guide plate 120 here can be but is not limited to being made of sheet metal.

[0049] According to the material conveying device of the embodiment of the present application, when it includes the track 600, it is a rail-guided vehicle (RGV stands for Rail Guided Vehicle), also called a rail-guided shuttle car, which is a storage and retrieval device in an automated warehousing system. When the material receiving station 700 includes the first station 710 and the second station 720, the loading and unloading direction of the material conveying device is no longer single, and its flexibility is high, which greatly improves the efficiency and accuracy of logistics transportation, and can be used for some more complex working conditions. For example, when used for brewing white wine, the first station 710 and the second station 720 can respectively receive sorghum or mash through the hopper 400, and then different materials can be transferred to the unloading station.

[0050] According to the material conveying device of the embodiment of the present application, when it is used to convey materials between the first station 710 and the second station 720, the working process is as follows: The hopper 400 filled with materials is transported to the first station 710 through logistics; the two sets of first limit members 230 in the material conveying device close to the first station 710 are automatically leveled; the chain mechanism 730 on the first station 710 and the second chain are started at the same time; the hopper 400 is transferred from the first station 710 to the second chain of the material conveying device.

[0051] After the hopper 400 completely enters the material receiving bracket 210 of the turning frame 200, the first position-limiting member 230 automatically resets, the hopper 400 moves until it is in close contact with the second position-limiting member 240, and the second chain stops moving.

[0052] The material conveying device automatically moves to the designated receiving bucket position of the first station 710, i.e., the material unloading station, through the track 600 on the ground. The reversing reduction motor 330 drives the sprocket 310 to rotate, so as to drive the reversing frame 200 to rotate to the material unloading position through the first chain 320. The reversing reduction motor 330 drives the reversing frame 200 to rotate counterclockwise about 165 degrees, and the material is unloaded through the guide plate 120 into the unloading port 110 and enters the next process.

[0053] The turning frame 200 is reset, the material conveying device moves to the first station 710, the first limit piece 230 is laid flat, the second chain and the chain mechanism 730 on the first station 710 are both started, the empty hopper 400 is transferred from the second chain to the first station 710, the first limit piece 230 is reset, and the complete process of material transfer at the first station 710 is completed.

[0054] The hopper 400 filled with materials is transported to the second station 720 through logistics; the two sets of second limit members 240 in the material conveying device close to the second station 720 are automatically leveled; the chain mechanism 730 on the second station 720 is started simultaneously with the second chain; the hopper 400 is transferred from the second station 720 to the second chain of the material conveying device.

[0055] After the hopper 400 completely enters the material receiving bracket 210 of the overturning frame 200, the second position-limiting member 240 automatically resets, the hopper 400 moves until it is in close contact with the second position-limiting member 240, and the second chain stops moving.

[0056] The material conveying device automatically moves to the designated receiving bucket position of the second station 720, i.e., the material unloading station, through the track 600 on the ground. The reversing reduction motor 330 drives the sprocket 310 to rotate, so as to drive the reversing frame 200 to rotate to the material unloading position through the second chain. The reversing reduction motor 330 drives the reversing frame 200 to rotate counterclockwise about 165 degrees, and the material is unloaded through the guide plate 120 into the unloading port 110 and enters the next process.

[0057] The turning frame 200 is reset, the material conveying device moves to the second station 720, the second limit member 240 is laid flat, the second chain and the chain mechanism 730 on the second station 720 are started, the empty hopper 400 is transferred from the second chain to the second station 720, the second limit member 240 is reset, and the complete process of material transfer at the second station 720 is completed.
