Description

Technical Field

[0001] The present invention belongs to the technical field of distributing materials in multiple bins, and particularly relates to a device and method for distributing materials in multiple bins. Background Art

[0002] At present, the transportation of bulk materials is mainly achieved through railway, highway, water transportation and other means. How to load bulk materials quantitatively and efficiently is a key link affecting transportation efficiency. The mainstream in the market uses a single large hopper scale for rapid quantitative loading equipment for material loading. Although its loading efficiency and loading accuracy are relatively high, due to the need to set up a huge receiving buffer bin, the loading equipment is tall and large, which not only lengthens the construction period of the equipment, increases the manufacturing cost and maintenance cost, but also increases the required conveying height of the materials, resulting in higher energy consumption for material transmission.

[0003] Therefore, a rotary three-hopper loading device is proposed. For example, a Chinese patent with the patent number 201810611215.5 proposes a rotary three-hopper rapid quantitative loading method. This method arranges three 120-degree sector-shaped hoppers on a plane, and realizes the alternate loading, weighing and unloading of the hoppers by slow rotation, optimizing the loading and unloading time and reducing the height of the loading station. However, this method requires driving the bin and the materials in the bin to rotate, which not only makes the force and structure of the rotating mechanism more complex, greatly increases the manufacturing cost and energy consumption, and has poor operation reliability, but also because the materials are in a dynamic rotating state as the bin rotates, its weighing method is rotary dynamic weighing, resulting in poor weighing accuracy. Summary of the Invention

[0024] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments and corresponding drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] The following will detail the technical solutions provided by each embodiment of the present invention in conjunction with the drawings.

[0026] In conjunction with Figures 1 to 3As shown in the figure, in an embodiment of the present invention, a multi-bin feeding device is disclosed, which includes a fixed chute 1, a rotating chute 2, and a connecting cover 3. Among them, the fixed chute 1 is fixedly arranged on the support frame of the loading equipment (not shown in the figure), and is used to receive the materials conveyed by the belt 4. The rotating chute 2 is located between the fixed chute 1 and the connecting cover 3. The upper end of the rotating chute 2 is movably connected to the fixed chute 1, and the lower end of the rotating chute 2 is fixedly connected to the connecting cover 3. The connecting cover 3 is movably arranged above the four bins 5, for example, movably arranged on the bracket fixing the four bins 5, and the connecting cover 3 can move the lower end of the rotating chute 2 to communicate with different bins 5.

[0027] In this embodiment, by arranging a movable rotating chute between the fixed chute and multiple bins, the movement of the rotating chute relative to multiple bins can be controlled to perform the feeding operation to different bins. Compared with the existing bin rotation design, in this embodiment, the rotating chute for guiding materials is designed as a movable component, while the bin for carrying materials is used as a fixed component, so that the force and structure of the movable component can be simpler, the manufacturing cost and energy consumption can be reduced, and the operation reliability can be improved.

[0028] Combined with Figure 3 As shown in the figure, in the multi-bin feeding device of this embodiment, the four bins 5 connected to the connecting cover 3 are arranged along the circumferential direction, and the connecting cover 3 is rotatably arranged above the four bins 5. In this way, by rotating, the rotating chute 2 can be sequentially communicated with the four bins 5, so as to realize the sequential continuous feeding operation to multiple bins.

[0029] Of course, in other embodiments, according to different design and use environments, the four bins can also be arranged in other positional relationships. For example, the four bins are arranged in a straight line in sequence. In this way, by movably connecting the upper end of the rotating chute to the fixed chute in a swingable manner and controlling the reciprocating linear movement of the rotating chute above the four bins, the feeding operation to the four bins can also be realized.

[0030] Combined with Figure 1 As shown in the figure, in the multi-bin feeding device of this embodiment, the rotating chute 2 is inclined between the fixed chute 1 and the connecting cover 3. The upper end of the rotating chute 2 is rotatably connected to the fixed chute 1, and the lower end of the rotating chute 2 is eccentrically connected to the connecting cover 3.

[0031] At this time, by controlling the rotation of the rotating chute relative to the fixed chute, the lower end of the rotating chute can be communicated with different bins as the connecting cover rotates synchronously while keeping the upper end position of the rotating chute unchanged, so as to realize the feeding operation to different bins. In this way, the control structure and complexity of the rotating chute can be further simplified, and the operation stability and reliability can be improved.

[0032] Combined with Figure 1 As shown, in the multi-bunker feeding device of this embodiment, there are also a slewing bearing 6, an external gear ring 7, a driving gear 8 and a motor 9. Among them, the slewing bearing 6 is located between the fixed chute 1 and the rotating chute 2, the external gear ring 7 is sleeved and fixed on the rotating chute 2, the driving gear 8 is arranged at the output end of the motor 9, and the driving gear 8 is meshed with the external gear ring 7 to drive the rotating chute 2 to rotate relative to the fixed chute 1.

[0033] At this time, by controlling the rotation of the motor, the rotation of the rotating chute relative to the fixed chute can be achieved through the meshing connection between the driving gear and the external gear ring, and then the connection cover can be driven to rotate relative to the multiple bunkers, realizing the switching operation between different bunkers during the feeding process.

[0034] Among them, in the multi-bunker feeding device of this embodiment, the motor 9 preferably adopts a servo motor, so as to accurately control the rotation process of the rotating chute 2 and improve the feeding accuracy. At the same time, a speed reducer 10 is also arranged at the output end of the motor 9. The speed reducer 10 can reduce the speed and increase the torque of the motor 9, further improving the rotation control accuracy and stability of the rotating chute 2.

[0035] Combined with Figure 3 As shown, in the multi-bunker feeding device of this embodiment, weighing sensors 13 and matching weighing instruments are respectively arranged on the four bunkers 5, so that the four bunkers 5 can be used as weighing bins. In this way, during the feeding process, the received material quantity in the bunker can be measured statically in real time, thus greatly improving the control accuracy of the feeding quantity, the feeding quality and the overall loading effect.

[0036] In addition, in the multi-bunker feeding device of this embodiment, a sealing member is also arranged between the connection cover 3 and the four bunkers 5 to seal the bunkers 5 and prevent dust from overflowing during the feeding process.

[0037] Combined with Figure 3 As shown, in the multi-bunker feeding device of this embodiment, the connection cover 3 is arranged above the four 90-degree square bunkers 5, so as to realize the sequential feeding operation of the multi-bunker feeding device for the four bunkers 5. Of course, in other embodiments, the connection cover can also be arranged above other numbers of bunkers, such as above three 120-degree sector hoppers, so as to realize the use of the multi-bunker feeding device in loading equipment with different numbers of bunkers.

[0038] Combined with Figure 1As shown in the figure, in the multi-bunker feeding 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, so as to accurately control the start and stop of the rotating chute, improve the feeding accuracy. At the same time, a plurality of reinforcing ribs 12 are also provided on the connecting cover 3 to increase the structural strength of the connecting cover 3 and improve its stable reliability during the movement with the rotating chute 2, thereby ensuring the feeding quality.

[0039] Combined with Figures 1 to 3 As shown in the figure, when using the multi-bunker feeding device of this embodiment for feeding, the specific operation steps are as follows:

[0040] Step S1, Adjust the position: Move the lower end of the rotating chute to a position where it is connected to the bunker to be fed among the multiple bunkers.

[0041] Specifically, start the motor 9, control the rotation of the rotating chute 2 relative to the fixed chute 1 through the driving gear 8 and the external gear ring 7, and drive the connecting cover 3 to rotate, so that the rotating chute 2 rotates to be connected to the first bunker 5. Among them, Figure 3 The four bunkers 5 marked with A, B, C, and D in clockwise order as shown in the figure respectively correspond to the first bunker, the second bunker, the third bunker, and the fourth bunker.

[0042] Step S2, Feeding: Start the feeding mechanism, introduce the material into the fixed chute, and pass through the rotating chute into the corresponding bunker.

[0043] Specifically, start the belt 4 as the feeding mechanism, use the belt 4 to convey the material into the fixed chute 1, and the material then enters the first bunker 5 through the rotating chute 2, so as to feed the first bunker 5.

[0044] Step S3, Switch the position: After feeding a predetermined amount of material into the corresponding bunker, drive the lower end of the rotating chute to move so that the lower end of the rotating chute is connected to the adjacent bunker to be fed.

[0045] Specifically, when the material conveyed to the first bunker 5 reaches the predetermined amount, drive the rotating chute 2 to rotate to be connected to the second bunker 5 to start the feeding operation for the second bunker 5.

[0046] Among them, in the operation of step S2, first, the preset receiving amount mas of the first bin 5 is obtained, and then the binning is carried out into the first bin 5. As the materials in the first bin 5 increase, when the difference (mas - ma) between the weighed receiving amount ma of the first bin 5 and its preset receiving amount mas reaches the preset value, step S3 is started. That is, while continuing to carry out binning into the first bin 5, the rotating chute 2 is driven to move in the direction of the second bin 5, so that the rotating chute 2 gradually reduces the binning amount to the first bin and simultaneously starts the binning operation to the second bin. When the difference between the weighed receiving amount ma of the first bin and its preset receiving amount mas is 0, the lower end of the rotating chute 2 is completely switched to communicate with the second bin, so as to complete the binning operation of the first bin during the gradual rotation of the rotating chute 2. Through the above binning operation, a combined binning method of rapid binning operation with large flow rate in the early stage and precise binning operation in the later stage is formed. Thus, not only can the binning amount of the first bin be gradually reduced to improve the binning accuracy of the first bin, but also the binning operation of the second bin can be started as early as possible to improve the binning efficiency.

[0047] Among them, the preset value reached by the difference (mas - ma) between the weighed receiving amount ma of the first bin 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 bin, the rotation speed of the motor-driven rotating chute, the outlet size of the rotating chute, and the distance between adjacent bins, so as to achieve a gradual transition of binning to two adjacent bins.

[0048] In addition, in the operation of step S2, the preset receiving amount of any bin does not exceed the loading amount of a single loading unit. That is, if loading a train, the preset receiving amount of each of the four bins does not exceed the loading amount of a single train car. In this way, the loading operation of a train car is completed by multiple bins, so as to accurately control the subsequent loading amount and improve the overall loading efficiency. Taking the quantitative loading of a car by two bins as an example, the specific process of the above operation is as follows:

[0049] First, obtain the car body information table of the train, and get the rated loading capacity m1 of the first car. Accordingly, set the preset receiving capacity mas of the first bin to half of the rated loading capacity m1, that is, mas = m1 / 2. Then, conduct feeding into the first bin and monitor the weighed receiving capacity ma of the first bin in real time. When the difference (mas - ma) between the weighed receiving capacity ma and the preset receiving capacity mas of the first bin shrinks to 20% of the rated loading capacity m1, that is, (mas - ma) = m1 / 5, control the rotating chute to rotate towards the second bin, gradually reduce the size of the feeding opening for feeding into the first bin, and start feeding into the second bin until the difference (mas - ma) between the weighed receiving capacity ma and the preset receiving capacity mas of the first bin shrinks to zero. Rotate the rotating chute completely to the second bin, thus completing the feeding operation for the first bin, and record the actual receiving capacity mah of the first bin at this time. Then, start to control the feeding operation for the second bin. The preset receiving capacity mbs of the second bin can be set as mbs = m1 - mah, that is, the loading of the first car is jointly completed by the first bin and the second bin. During the process of feeding into the second bin, monitor the weighed receiving capacity mb of the second bin in real time. When the difference (mbs - mb) between the weighed receiving capacity mb and the preset receiving capacity mbs of the second bin shrinks to 20% of the rated loading capacity m1, that is, (mbs - mb) = m1 / 5, control the rotating chute to rotate towards the third bin, gradually reduce the size of the feeding opening for feeding into the second bin, and start feeding into the third bin until the difference (mbs - mb) between the weighed receiving capacity mb and the preset receiving capacity mbs of the second bin shrinks to zero. Rotate the rotating chute completely to the third bin to complete the feeding operation for the second bin. After that, the feeding operations for the subsequent third bin and fourth bin can be carried out with reference to the feeding operations for the first bin and the second bin above.

[0050] Meanwhile, during the above feeding process, after the first bin finishes feeding, the first car can be moved to the loading position, the first bin is opened, and the materials in the first bin are loaded into the first car. After the first bin finishes discharging, close the first bin and record its actual discharging capacity maf. Then, open the second bin to continue loading until the materials in the second bin are discharged completely, close the second bin and record its actual discharging capacity mbf. In this way, the loading capacity of the first car is maf + mbf. After that, repeat the above operations, and the loading of the second car can be completed through the third bin and the fourth bin.

[0051] By completing one round of the fabric feeding operation and discharging operation for four bins, the loading of two cars can be completed. By repeating the fabric feeding operation and discharging operation for the four bins, quantitative loading can be completed for the subsequent third / fourth cars, fifth / sixth cars, …, and even the entire train.

Under the above teaching of the present invention, those skilled in the art can make other improvements or deformations on the basis of the above embodiments.
