Description

Technical Field

[0001] This utility model belongs to the field of multi-compartment material distribution technology, and specifically relates to a multi-compartment material distribution device. Background Technology

[0002] Currently, the transportation of bulk materials is mainly achieved through railways, highways, and waterways. How to load bulk materials quantitatively and efficiently is a key factor affecting transportation efficiency. The mainstream method on the market uses single large hopper scales for rapid, quantitative loading. While this method offers high loading efficiency and accuracy, it requires a large receiving buffer hopper, resulting in a bulky loading device. This not only lengthens the construction period and increases manufacturing and maintenance costs but also raises the required material conveying height, leading to higher energy consumption during material transport.

[0003] Therefore, rotary three-bucket loading devices have been proposed. For example, Chinese patent number 201810611215.5 proposes a rotary three-bucket rapid quantitative loading method. This method arranges three 120-degree sector-shaped hoppers on a plane, and achieves alternating loading, weighing, and unloading of the hoppers through slow rotation, optimizing loading and unloading time and reducing loading station height. However, this method requires driving the hopper and the material inside to rotate, which not only makes the force and structure of the rotating mechanism more complex, significantly increasing manufacturing costs and energy consumption, and resulting in poor operational reliability, but also, because the material is in a dynamic rotational state with the rotation of the hopper, its weighing method is a rotational dynamic metering, leading to poor metering accuracy.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] Combination Figures 1 to 3 As shown in the figure, one embodiment of this utility model discloses a multi-hopper material distribution device, including a fixed chute 1, a rotating chute 2, and a connecting cover 3. The fixed chute 1 is fixedly mounted on the support frame of the loading equipment (not shown in the figure) and is used to receive materials conveyed by the belt conveyor 4. The rotating chute 2 is located between the fixed chute 1 and the connecting cover 3, with its upper end movably connected to the fixed chute 1 and its lower end fixedly connected to the connecting cover 3. The connecting cover 3 is movably mounted above the four hoppers 5, for example, movably mounted on a support frame that fixes the four hoppers 5, and the connecting cover 3 can move the lower end of the rotating chute 2 to communicate with different hoppers 5.

[0024] In this embodiment, by setting a movable rotating chute between a fixed chute and multiple silos, the rotating chute can be controlled to move relative to the multiple silos to perform material distribution operations to different silos. Compared with the existing silo rotation design, this embodiment designs the rotating chute that guides the material as a movable component, while the silos that carry the material are fixed components. This simplifies the stress and structure of the movable component, reduces manufacturing costs and energy consumption, and improves operational reliability.

[0025] Combination Figure 3 As shown, in the multi-hopper material distribution device of this embodiment, four hoppers 5 connected to the connecting cover 3 are arranged along the circumferential direction, while the connecting cover 3 is rotatably positioned above the four hoppers 5. In this way, by rotating, the rotating chute 2 can be connected to the four hoppers 5 in sequence, thereby realizing the continuous material distribution operation to multiple hoppers.

[0026] Of course, in other embodiments, depending on the design and usage environment, the four hoppers can be arranged in other positions. For example, the four hoppers can be arranged in a straight line. In this way, by making a swingable connection between the upper end of the rotating chute and the fixed chute and controlling the rotating chute to move back and forth in a straight line above the four hoppers, the material feeding operation to the four hoppers can also be realized.

[0027] Combination Figure 1 As shown, in the multi-hopper material distribution device of this embodiment, the rotating chute 2 is inclinedly disposed between the fixed chute 1 and the connecting cover 3, and the upper end of the rotating chute 2 is rotatably connected to the fixed chute 1, while the lower end of the rotating chute 2 is eccentrically connected to the connecting cover 3.

[0028] At this point, by controlling the rotation of the rotating chute relative to the fixed chute, the lower end of the rotating chute can be connected to different hoppers while keeping the upper end of the rotating chute stationary, thus enabling material distribution to different hoppers. This further simplifies the control structure and complexity of the rotating chute and improves the stability and reliability of its operation.

[0029] Combination Figure 1 As shown, the multi-hopper material distribution device in this embodiment also includes a rotary bearing 6, an external gear ring 7, a drive gear 8, and a motor 9. The rotary bearing 6 is located between the fixed chute 1 and the rotating chute 2. The external gear ring 7 is fitted and fixed to the rotating chute 2. The drive gear 8 is located at the output end of the motor 9 and meshes with the external gear ring 7 to drive the rotating chute 2 to rotate relative to the fixed chute 1.

[0030] At this point, by controlling the rotation of the motor, the meshing connection between the drive gear and the external gear ring can be used to make the rotating chute rotate relative to the fixed chute, thereby driving the connecting cover to rotate relative to multiple hoppers, realizing the switching operation between different hoppers during the material distribution process.

[0031] In this embodiment of the multi-hopper material distribution device, a servo motor is preferentially used for motor 9, which enables precise control of the rotation process of the rotating chute 2 and improves the accuracy of material distribution. At the same time, a reducer 10 is also provided at the output end of motor 9. The reducer 10 can reduce the speed of motor 9 and increase the torque, further improving the rotation control accuracy and stability of the rotating chute 2.

[0032] Combination Figure 3As shown, in the multi-hopper material distribution device of this embodiment, each of the four hoppers 5 is equipped with a weighing sensor 13 and a matching weighing instrument, enabling the four hoppers 5 to function as weighing hoppers. In this way, during the material distribution process, the amount of material received in the hoppers can be statically measured in real time, thereby greatly improving the control accuracy of the material distribution, improving the material distribution quality, and enhancing the overall loading effect.

[0033] In addition, in the multi-hopper material distribution device of this embodiment, a sealing element is provided between the connecting cover 3 and the four hoppers 5 to achieve sealing of the hoppers 5 and prevent dust from overflowing during the material distribution process.

[0034] Combination Figure 3 As shown, in this embodiment of the multi-hopper material distribution device, the connecting cover 3 is disposed above the four 90-degree square hoppers 5, thereby enabling the multi-hopper material distribution device to sequentially distribute material to the four hoppers 5. Of course, in other embodiments, the connecting cover can also be disposed above other numbers of hoppers, such as above three 120-degree fan-shaped hoppers, thereby enabling the multi-hopper material distribution device to be used in loading equipment with different numbers of hoppers.

[0035] Combination Figure 1 As shown, in the multi-hopper material distribution device of this embodiment, the rotating chute 2 adopts a rigid pipe structure, and an auxiliary support rod 11 is provided between the rotating chute 2 and the connecting cover 3. This allows for precise control of the starting and stopping of the rotating chute, improving the material distribution accuracy. At the same time, multiple reinforcing ribs 12 are provided on the connecting cover 3 to increase the structural strength of the connecting cover 3, improve its stability and reliability as it moves with the rotating chute 2, and thus ensure the quality of the material distribution.

[0036] Combination Figures 1 to 3 As shown, the specific operating steps for using the multi-hopper material distribution device of this embodiment for material distribution are as follows:

[0037] Step S1, Adjust position: Move the lower end of the rotating chute to a position that connects with the hoppers in the multiple hoppers where material is to be distributed.

[0038] Specifically, the motor 9 is started, which drives the gear 8 and the external gear ring 7 to control the rotation of the rotating chute 2 relative to the fixed chute 1, thereby causing the connecting cover 3 to rotate, so that the rotating chute 2 rotates to connect with the first hopper 5. Among these steps... Figure 3 The four hoppers 5, labeled A, B, C, and D in a clockwise direction, correspond to the first, second, third, and fourth hoppers, respectively.

[0039] Step S2, Material feeding: Start the feeding mechanism to introduce the material into the fixed chute, and then into the corresponding hopper through the rotating chute.

[0040] Specifically, the belt 4, which serves as the feeding mechanism, is started to transport the material to the fixed chute 1. The material then enters the first hopper 5 through the rotating chute 2, thereby distributing the material to the first hopper 5.

[0041] Step S3, switch position: After a predetermined amount of material is placed into the corresponding hopper, drive the lower end of the rotating chute to move so that the lower end of the rotating chute is connected to the adjacent hopper to be placed.

[0042] Specifically, when the material delivered to the first hopper 5 reaches the predetermined amount, the rotating chute 2 is driven to rotate and connect with the second hopper 5 to begin the material distribution operation to the second hopper 5.

[0043] In step S2, the preset receiving amount mas of the first hopper 5 is first obtained, and then material is distributed into the first hopper 5. As the material in the first hopper 5 increases, when the difference (mas-ma) between the weighing receiving amount ma of the first hopper 5 and its preset receiving amount mas reaches a preset value, step S3 begins. That is, while continuing to distribute material into the first hopper 5, the rotating chute 2 is driven to move towards the second hopper 5, so that the rotating chute 2 gradually reduces the amount of material distributed into the first hopper and simultaneously begins to distribute material into the second hopper. When the difference between the weighing receiving amount ma of the first hopper and its preset receiving amount mas is 0, the lower end of the rotating chute 2 is completely switched to be connected to the second hopper, thereby completing the distribution operation of the first hopper as the rotating chute 2 gradually rotates. Through the above-described material placement process, a combined material placement method is formed, which involves a large volume of material placement in the early stage and a precise material placement operation in the later stage. This not only allows for a gradual reduction in the amount of material placed in the first hopper, improving the precision of material placement in the first hopper, but also enables the material placement operation in the second hopper to begin earlier, thereby improving material placement efficiency.

[0044] The preset value of the difference (mas-ma) between the weighing amount ma of the first hopper and its preset receiving amount mas can be adjusted according to different designs. Specifically, it can be set with reference to parameters such as the preset receiving amount of the hopper, the rotation speed of the motor-driven rotating chute, the discharge port size of the rotating chute, and the distance between adjacent hoppers, so as to achieve a gradual transition of material distribution to the two adjacent hoppers.

[0045] Furthermore, in step S2 above, the preset receiving capacity of any one of the hoppers does not exceed the loading capacity of a single loading unit. That is, if loading is done on a train, the preset receiving capacity of each of the four hoppers does not exceed the loading capacity of a single train car. This allows multiple hoppers to complete the loading operation for one train car, thus enabling accurate control of subsequent loading quantities and improving overall loading efficiency. Taking the quantitative loading of one train car by two hoppers as an example, the specific process of the above operation is as follows:

[0046] First, obtain the train's carriage information table to get the rated load capacity m1 of the first carriage. Based on this, set the preset receiving capacity mas of the first hopper to half of the rated load capacity m1, i.e., mas = m1 / 2. Next, feed material into the first hopper and monitor the weighing receiving capacity ma of the first hopper in real time. When the difference (mas-ma) between the weighing receiving capacity ma of the first hopper and its preset receiving capacity mas decreases to 20% of the rated load capacity m1, i.e., (mas-ma) = m1 / 5, control the rotary chute to rotate towards the second hopper, gradually reducing the material opening size for feeding material into the first hopper and starting to feed material into the second hopper, until the difference (mas-ma) between the weighing receiving capacity ma of the first hopper and its preset receiving capacity mas decreases to zero. Then, rotate the rotary chute completely into the second hopper, thus completing the feeding operation into the first hopper, and record the actual value of the first hopper at this time. The actual receiving capacity is mAh; then, the material distribution operation of the second hopper is controlled. The preset receiving capacity mbs of the second hopper can be set as mbs = m1 - mAh, that is, the loading of the first car is completed by the first and second hoppers. During the material distribution to the second hopper, the weighing receiving capacity mb of the second hopper is monitored in real time. When the difference (mbs - mb) between the weighing receiving capacity mb of the second hopper and its preset receiving capacity mbs is reduced to 20% of the rated loading capacity m1, that is, (mbs - mb) = m1 / 5, the rotary chute is controlled to rotate towards the third hopper, gradually reducing the material opening size for material distribution to the second hopper and starting material distribution to the third hopper, until the difference (mbs - mb) between the weighing receiving capacity mb of the second hopper and its preset receiving capacity mbs is reduced to zero, the rotary chute is completely rotated to the third hopper, and the material distribution operation of the second hopper is completed. After that, you can refer to the material placement operations of the first and second hoppers to carry out the material placement operations of the third and fourth hoppers.

[0047] Meanwhile, during the material distribution process, once the first hopper has finished distributing material, the first car can be moved to the loading position, the first hopper opened, and the material in the first hopper loaded into the first car. After the first hopper has finished discharging, it is closed and the actual discharge amount maf is recorded. Then, the second hopper is opened to continue loading until the material in the second hopper is completely discharged. The second hopper is then closed and its actual discharge amount mbf is recorded. Thus, the loading amount of the first car is maf + mbf. This process is repeated to load the second car using the third and fourth hoppers.

[0048] By completing one round of material placement and unloading operations on the four hoppers, the loading of two cars can be completed. By repeating the material placement and unloading operations on the four hoppers, the subsequent third / fourth cars, fifth / sixth cars, ..., and so on, can be loaded to the required quantity for the entire train.

Under the teachings of this utility model, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this utility model, and the scope of protection of this utility model should be determined by the scope of the claims.
