[0058] The technical solution of the utility model is further elaborated in detail below in conjunction with the drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the utility model.

In the following description, the expression "some embodiments" is involved, which describes a subset of all possible embodiments, but it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0059] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0060] like Figure 1-6 As shown, in one embodiment of the utility model, a bucket elevator includes a frame assembly 10, a bucket mechanism 20 connected to the frame assembly 10 for relative motion, and a lifting mechanism 40 for driving the bucket mechanism 20 to switch between a material taking station and a material feeding station. The bucket mechanism 20 includes a hopper 21 and a locking mechanism 30. When the bucket mechanism 20 is at the material taking station, the hopper 21 receives a material basket 60 containing materials to be fed. When the bucket mechanism 20 is transferred to the material feeding station, the bucket mechanism 20 dumps the material in the material basket 60 into the feeding area through the tipping action of the hopper 21, thereby completing the feeding operation. When the material basket 60 is located in the hopper 21, the locking mechanism 30 is used to lock the position of the material basket 60 in the hopper 21. During the switching process between the material picking station and the feeding station, the tipping mechanism 20 keeps the position of the material basket 60 in the hopper 21 stable and ensures that the tipping mechanism 20 can smoothly perform the tipping action of the hopper 21 during the feeding operation. This tipping elevator uses an automated tipping action and can quickly switch between the material picking and feeding stations, thereby improving the efficiency of the feeding operation. The automated operation reduces the risk of direct contact between personnel and materials, and reduces safety accidents during the work process. The design of the tipping mechanism 20 allows it to be suitable for material baskets 60 of different sizes and weights, and has good adaptability. The tipping elevator reduces the need for manual material handling and reduces the labor intensity of workers.

[0061] like Figure 1-3As shown, in one embodiment of the utility model, the frame assembly 10 includes a base frame 11 and two columns 12 located on opposite sides of the base frame 11, and the tipping mechanism 20 is driven by the lifting mechanism 40 to move along the height direction of the column 12 to achieve switching between the material picking station and the material feeding station. When the tipping mechanism 20 is located at the bottom end of the column 12, the tipping mechanism 20 is in the material picking station; when the tipping mechanism 20 is located at the top end of the column 12, the tipping mechanism 20 is in the material feeding station. By moving the tipping mechanism 20 along the height direction of the column 12, the automation of material picking and feeding can be realized in a limited space. The tipping mechanism 20 can move freely on the column 12, so that the positions of material picking and feeding can be adjusted as needed, thereby improving the flexibility of operation. The fixed positions of the tipping mechanism 20 at the bottom and top of the column 12 can accurately locate the material picking station and the material feeding station, thereby ensuring the accuracy of material feeding. The moving path of the tipping mechanism 20 is clear, which is convenient for monitoring and control, and helps to discover and solve problems in a timely manner.

[0062] like Figure 1-3 As shown, in one embodiment of the utility model, the lifting mechanism 40 includes a guide assembly 41 and a lifting assembly 42. The guide assembly 41 guides the bucket mechanism 20 to move along the height direction of the column 12, and the lifting assembly 42 is used to drive the bucket mechanism 20 to move. The guide assembly 41 ensures that the bucket mechanism 20 moves accurately along the height direction of the column 12, which helps to improve the accuracy and repeatability of feeding. The existence of the guide assembly 41 helps to reduce swing or offset when the bucket mechanism 20 moves, and improves the stability of the entire system. The lifting assembly 42 provides power, so that the bucket mechanism 20 can stop and start at any position of the column 12, which increases the flexibility of operation.

[0063] like Figure 1-3As shown, in one embodiment of the utility model, the guide assembly 41 includes four groups of sub-guide assemblies 410, wherein two groups of the sub-guide assemblies 410 are arranged one-to-one at the front and rear opposite ends of one of the columns 12, and the other two groups of the sub-guide assemblies 410 are arranged one-to-one at the front and rear opposite ends of another column 12, each of the sub-guide assemblies 410 includes a guide shaft 4100 arranged on the column 12 and arranged along the height direction of the column 12 and a linear bearing 4101 sleeved on the guide shaft 4100, and the tipping bucket mechanism 20 is connected to the linear bearing 4101 of each of the sub-guide assemblies 410. Each sub-guide assembly 410 includes a guide shaft 4100 and a linear bearing 4101. This design can provide precise guidance to ensure that the bucket mechanism 20 moves smoothly along the height direction of the column 12. The sub-guide assemblies 410 are distributed at the front and rear ends of the column 12. This symmetrical layout helps to improve the stability and rigidity of the entire lifting mechanism 40. The use of linear bearings 4101 can reduce the friction and wear of the bucket mechanism 20 during movement, thereby extending the service life of the equipment. The modular design of the sub-guide assemblies 410 makes maintenance and replacement more convenient because they can be operated independently of other systems.

[0064] like Figure 1-3 As shown, in one embodiment of the utility model, the lifting assembly 42 includes a driving shaft 420 that is simultaneously rotatably connected to the top ends of the two columns 12, a driven shaft 421 that is simultaneously rotatably connected to the bottom ends of the two columns 12, a driving sprocket 422 mounted on the driving shaft 420, a driven sprocket 423 mounted on the driven shaft 421, a chain 424 that is simultaneously mounted on the driving sprocket 422 and the driven sprocket 423, and a lifting motor 425 that drives the driving shaft 420 to rotate, and the tipping bucket mechanism 20 is connected to the chain 424.

[0065] like Figure 1-3 As shown, in one embodiment of the utility model, the tipping mechanism 20 further includes a first moving plate 22 connected to the two linear bearings 4101 on one of the columns 12, a second moving plate 23 connected to the two linear bearings 4101 on another column 12, a tipping shaft 24 connected to the first moving plate 22 and the second moving plate 23 for simultaneous rotation, and a tipping motor 25 for driving the tipping shaft 24 to rotate, wherein the tipping shaft 24 is connected to the hopper 21. The tipping motor 25 drives the tipping shaft 24 to rotate, thereby driving the hopper 21 connected to the tipping shaft 24 to rotate, so as to smoothly perform the tipping action of the hopper 21.

[0066] like Figure 1-6As shown, in one embodiment of the utility model, the locking mechanism 30 includes a locking assembly 31, and the locking assembly 31 includes two vertical rods 312 arranged at intervals and in parallel on the hopper 21, a fixed plate 310 arranged on the two vertical rods 312, a movable pressing plate 311 which is sleeved on the two vertical rods 312 and can move along the length direction of the vertical rods 312, and a first connecting block 313 and a second connecting block 314 arranged between the fixed plate 310 and the movable pressing plate 311, wherein the A end of the first connecting block 313 (for the convenience of simplifying the description, the A end and the B end referred to in the full text are two ends arranged oppositely on the four connecting blocks, as shown in FIG. Figure 4-6 As shown in the figure, the first connecting block 313 is connected to the fixed plate 310 through the first hinge point 318, the A end of the second connecting block 314 is connected to the movable clamping plate 311 through the second hinge point 319, the B end of the first connecting block 313 is connected to the B end of the second connecting block 314 through the third hinge point 320, when the locking mechanism 30 is in the unlocked state, the third hinge point 320 is located on one side of the line connecting the first hinge point 318 and the second hinge point 319, when the locking mechanism 30 is in the locked state, the third hinge point 320 is located on the other side of the line connecting the first hinge point 318 and the second hinge point 319, and the first connecting block 313 is blocked by the limit pin 317 set on the fixed plate 310, at this time, the movable clamping plate 311 presses the material basket 60 tightly into the hopper 21 to complete the locking of the material basket 60.

[0067] like Figure 1-6As shown, in one embodiment of the utility model, the locking assembly 31 also includes a third connecting block 315 and a fourth connecting block 316, the B end of the third connecting block 315 is hinged to the B end of the first connecting block 313 and the B end of the second connecting block 314 at the same time, the A end of the third connecting block 315 is hinged to the A end of the fourth connecting block 316, and the middle part of the fourth connecting block 316 is hinged to the fixing plate 310, and the locking mechanism 30 also includes a pushing assembly 33 for pushing the third hinge point 320 from one side of the line connecting the first hinge point 318 and the second hinge point 319 to the other side until the first connecting block 313 is blocked by the limit pin 317, and the pushing assembly 33 includes a core shaft 330 arranged on the frame assembly 10, a core shaft 330 sleeved on the core shaft A swing frame 332 is on the shaft 330 and can swing around the core shaft 330 at a small angle, and a toggle shaft 331 is arranged on the swing frame 332. The B end of the fourth connecting block 316 is provided with a slot 321 for the toggle shaft 331 to be inserted. When the tipping bucket mechanism 20 is in the material picking station, the toggle shaft 331 is inserted into the slot 321 at the B end of the fourth connecting block 316. During the switching process of the tipping bucket mechanism 20 from the material picking station to the material feeding station, the fourth connecting block 316 is forced to swing by the toggle shaft 331 after moving with the hopper 21, and then the third hinge point 320 is pushed from one side of the line connecting the first hinge point 318 and the second hinge point 319 to the other side through the third connecting block 315 until the first connecting block 313 is blocked by the limit pin 317, and the locking is completed at this time. When the tipping mechanism 20 is switched from the material taking station to the material feeding station, the fourth connecting block 316 is forced to swing and the bayonet 321 of the fourth connecting block 316 gradually separates from the shifting shaft 331 .

[0068] During the switching process of the tipping bucket mechanism 20 from the feeding station to the picking station, after the fourth connecting block 316 moves with the hopper 21, the driving shaft 331 is re-engaged in the slot 321 at the B end of the fourth connecting block 316, and the fourth connecting block 316 is forced to swing back by the driving shaft 331, and then the third hinge point 320 is pulled back to the original side of the line connecting the first hinge point 318 and the second hinge point 319 through the third connecting block 315. At this time, the movable clamping plate 311 is not pressed tightly against the material basket 60 to complete the unlocking of the material basket 60.

[0069] like Figure 1As shown, in one embodiment of the utility model, a material platform 53 is provided at the top of the base frame 11, and the material platform 53 is used to temporarily store a material basket 60 containing materials to be thrown. The material platform 53 serves as a temporary storage area, and multiple material baskets 60 containing materials can be pre-stored, which can reduce the time for the bucket elevator to wait for material loading and improve the overall work efficiency. The existence of the material platform 53 allows the operator to load and unload the material basket 60 at a fixed position, simplifying the operation process. The material platform 53 can be designed according to different sizes and shapes of the material basket 60 to adapt to different material baskets 60.

[0070] like Figure 1-3 As shown, in one embodiment of the utility model, two power wheels 50 and two direction wheels 51 are arranged at the bottom of the chassis 11. The two power wheels 50 are used to realize the forward and backward movement of the bucket elevator, and the two direction wheels 51 are used to assist the bucket elevator in steering and maintaining stability. The chassis 11 is also provided with a direction handle 52 for controlling the direction wheel 51. The design of the power wheel 50 enables the bucket elevator to have the function of forward and backward movement, and can move in different working areas, thereby improving the flexibility of operation. The direction wheel 51 assists the bucket elevator in steering, ensuring the stability of the machine during movement and the accuracy of operation. The direction handle 52 arranged on the chassis 11 facilitates the operator to control the direction wheel 51, making the steering and movement of the machine more convenient and quick. The convenience of movement and steering enables the bucket elevator to quickly respond to different operation requirements and improve the overall operation efficiency. Through the configuration of the power wheel 50 and the direction wheel 51, the labor intensity of manually pushing and adjusting the position of the equipment is reduced. This design of movement and steering enables the bucket elevator to be used not only on a fixed production line, but also in occasions where frequent equipment movement is required.

[0071] In order to facilitate understanding of the tipping bucket elevator of the utility model embodiment, the specific feeding and use process of the tipping bucket elevator is further explained below.

[0072] 1. Material collection process: In the initial state of the bucket elevator, the bucket mechanism 20 is located at the bottom of the column 12, and the bucket mechanism 20 is at the material collection station. After the material basket 60 containing the material to be thrown is manually lifted and placed on the material platform 53, the material basket 60 is pushed into the hopper 21 of the bucket mechanism 20. That is, when the bucket mechanism 20 is at the material collection station, the hopper 21 receives the material basket 60 containing the material to be thrown (such as Figure 1 shown);

[0073] 2. Switching process from the material taking station to the material feeding station: the lifting motor 425 drives the driving shaft 420 to rotate, thereby driving the driving sprocket 422 to rotate, thereby driving the chain 424 to move, and the tipping mechanism 20 connected to the chain 424 is driven by the lifting motor 425 under the guidance of the guide shaft 4100 and moves upward along the height direction of the column 12, and the fourth connecting block 316 is forced to swing by the toggle shaft 331 after the bucket 21 in the tipping mechanism 20 moves, and then the third hinge 316 is moved by the third connecting block 315. The contact point 320 is pushed from one side of the line connecting the first hinge point 318 and the second hinge point 319 to the other side until the first connecting block 313 is blocked by the limiting pin 317. At this time, the first connecting block 313 and the second connecting block 314 form a stable position state. At the same time, the movable pressing plate 311 hinged to the second connecting block 314 is driven by the second connecting block 314 to move downward until the movable pressing plate 311 presses the material basket 60 tightly into the hopper 21 (such as Figure 5 As shown), to complete the locking of the material basket 60, during the upward movement of the tipping mechanism 20, the fourth connecting block 316 is forced to swing, and the bayonet 321 of the fourth connecting block 316 will gradually disengage from the toggle shaft 331 (as shown in FIG. Figure 6 As shown in FIG. 1 , the lifting motor 425 drives the bucket mechanism 20 to move upward until the bucket mechanism 20 reaches the top of the column 12 (as shown in FIG. 1 ). Figure 2 As shown), the bucket mechanism 20 is switched from the material taking station to the material feeding station. A limit switch can be set at the material taking station and the material feeding station. The limit switch is used to confirm the stop position of the bucket mechanism 20. The limit switch ensures that the bucket mechanism 20 stops at a preset position to prevent it from moving to an unsafe area, thereby avoiding possible accidents. The limit switch can be used in conjunction with the control system to realize automatic control of the bucket mechanism 20 and improve the automation level of the entire bucket elevator.

[0074] 3. Feeding process: The tipping motor 25 drives the tipping shaft 24 to rotate, and then drives the hopper 21 connected to the tipping shaft 24 to rotate. The tipping mechanism 20 dumps the material in the material basket 60 and feeds it into the feeding area (such as Figure 3 As shown), in order to complete the feeding operation, a limit switch can be set at each of the two stop positions of the hopper 21 before and after the bucket is tipped. The limit switch is used to confirm the stop position of the hopper 21. The limit switch ensures that the hopper 21 stops at a preset position to prevent it from moving to an unsafe area, thereby avoiding possible accidents. The limit switch can be used in conjunction with the control system to realize automatic control of the bucket tipping action of the hopper 21, thereby improving the automation level of the entire bucket elevator;

[0075] 4. Switching process from the feeding station to the picking station: the lifting motor 425 drives the driving shaft 420 to rotate, thereby driving the driving sprocket 422 to rotate, thereby driving the chain 424 to move, and the tipping mechanism 20 connected to the chain 424 is driven by the lifting motor 425 under the guidance of the guide shaft 4100 and moves downward along the height direction of the column 12. After the fourth connecting block 316 moves with the hopper 21 in the tipping mechanism 20, the toggle shaft 331 can be re-engaged in the fourth connecting block The fourth connecting block 316 is forced to swing back by the toggle shaft 331 in the bayonet 321 at the end of the connecting block 316B, and then the third hinge point 320 is pulled back to the original side of the line connecting the first hinge point 318 and the second hinge point 319 through the third connecting block 315.
