[0040] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0041] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0042] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0043] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0044] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0045] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0046] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0047] See also Figures 1 to 6 The present embodiment provides a weighing device, which includes a hopper 1, an adapter frame 2, a weighing plate 3, a load-bearing frame 4, and a plurality of weighing sensors 5. The hopper 1 is open on both the upper and lower sides. In the present embodiment, the upper part of the hopper 1 is trumpet-shaped, and the lower part is square cylinder-shaped. Such a configuration makes it easier to place the material in the hopper 1. In addition, the hopper 1 is made of welded iron material, and a plurality of reinforcing ribs are welded on the periphery to enhance the structural strength of the hopper 1.

[0048] Specifically, the hopper 1 is arranged on the adapter frame 2, and the adapter frame 2 includes a transfer channel that passes through from top to bottom, and the transfer channel is opposite to the outlet of the hopper 1. The weighing plate 3 is movably arranged on the adapter frame 2, and can open and close the outlet of the hopper 1, and the hopper 1 can carry materials when the outlet is closed. The supporting frame 4 includes a material discharge channel that passes through from top to bottom, and the material discharge channel is opposite to the transfer channel. A plurality of weighing sensors 5 are distributed on the supporting frame 4, and the supporting frame 4 carries the adapter frame 2 through a plurality of weighing sensors 5, and the plurality of weighing sensors 5 are configured to weigh the materials in the hopper 1.

[0049] It should be noted that the material in this embodiment is large garbage, and therefore, large equipment such as a grab bucket or a dump truck is usually used to load the large garbage, that is, large equipment such as a grab bucket or a dump truck is usually used to put the material into the hopper 1. However, large equipment such as a grab bucket or a dump truck is not convenient for taking out the large garbage in the hopper 1 from the upper open side of the hopper 1.

[0050] During the feeding process, the weighing plate 3 is first driven to close the outlet of the hopper 1, and then the material is transported from the upper open side of the hopper 1 into the hopper 1, and finally the material in the hopper 1 is weighed by a plurality of weighing sensors 5. With such a configuration, the weight of the large garbage added to the hopper 1 can be calculated in time, so that the output of the crushing production line can be calculated, and the output of the crushing production line can be accurately controlled.

[0051] During the unloading process, the weighing plate 3 is first driven to open the outlet of the hopper 1, and then the material in the hopper 1 falls downward out of the weighing device through the outlet of the hopper 1, the transfer channel on the adapter frame 2, and the unloading channel on the carrier frame 4, and the unloading is completed. This arrangement makes it easier to unload materials and is convenient to operate.

[0052] It should be noted that the working principle of the weighing sensor 5 is the existing technology. This embodiment does not make any improvement to the weighing sensor 5 itself, so it will not be described in detail. For example, the weighing sensor 5 selects a cantilever beam weighing sensor 5 made of alloy steel. The lower side of the cantilever beam weighing sensor 5 is fixed to the upper side of the carrier 4, and the upper side of the cantilever beam weighing sensor 5 is connected to the bottom of the adapter frame 2. It should also be noted that in this embodiment, four weighing sensors 5 are provided, and the four weighing sensors 5 are provided at the four corners of the carrier 4, so that the force points are more uniform.

[0053] Because the volume of large garbage is large, the volume of the hopper 1 is large, and correspondingly, the size of the weighing plate 3 used to close the outlet of the hopper 1 is also large. If the large-sized weighing plate 3 adopts the traditional flip opening and closing method, the weighing plate 3 will occupy a large space when working and be inconvenient to operate.

[0054] Therefore, in order to avoid the above problems, in the present embodiment, the weighing plate 3 includes a first plate 31 and a second plate 32 slidably disposed on the adapter frame 2, and the first plate 31 and the second plate 32 can be close to or away from each other.

[0055] It can be understood that by the first plate 31 and the second plate 32 approaching each other until they are joined, the outlet of the hopper 1 is closed, and conversely, by the first plate 31 and the second plate 32 moving away from each other, the outlet of the hopper 1 is opened. It can be understood that the opening and closing of the outlet of the hopper 1 is controlled by the sliding of the first plate 31 and the second plate 32, which has a simple structure and occupies a small space.

[0056] It should be noted that the weighing device further includes a driving member for driving the first plate 31 and the second plate 32 to move, and the driving member can be any linear driving structure in the prior art, such as a cylinder, an oil cylinder, a linear module, etc. In this embodiment, the driving member is an oil cylinder, and four oil cylinders are provided, two of which are used to drive the opposite sides of the first plate 31, and the other two oil cylinders are not described in detail because they drive the opposite sides of the second plate 32.

[0057] To improve the smoothness of sliding of the first plate 31 and the second plate 32 , a first guide assembly 6 for guiding the sliding of the first plate 31 is provided between the adapter frame 2 and the first plate 31 , and a second guide assembly 7 for guiding the sliding of the second plate 32 is provided between the adapter frame 2 and the second plate 32 .

[0058] In this embodiment, the structures of the first guide assembly 6 and the second guide assembly 7 are consistent. The structure of the first guide assembly 6 is taken as an example for explanation. The first guide assembly 6 includes two rectangular guide rails 61 and two sets of H-type track wheels 62. The two rectangular guide rails 61 are arranged on the adapter frame 2. The two sets of H-type track wheels 62 are arranged on the opposite sides of the first plate 31, and the two sets of H-type track wheels 62 are adapted to the two rectangular guide rails 61 in a one-to-one correspondence. In this way, the opposite sides of the first plate 31 can be guided, so that the first plate 31 can slide more smoothly.

[0059] Furthermore, the first guide assembly 6 further includes a triangular guide rail 63, which is disposed on the adapter frame 2 and is located between the two rectangular guide rails 61. A V-shaped guide wheel 64 is disposed on the first plate 31 and is adapted to correspond to the triangular guide rail 63. Such an arrangement can better guide the first plate 31. In addition, the two rectangular guide rails 61 and the one triangular guide rail 63 cooperate with each other to provide a greater load-bearing capacity.

[0060] In order to ensure that the maximum opening range of the first plate 31 and the second plate 32 does not exceed the maximum opening range of the outlet of the hopper 1, in this embodiment, a first limit assembly 8 is provided between the adapter frame 2 and the first plate 31, and the first limit assembly 8 is used to limit the maximum sliding stroke of the first plate 31. A second limit assembly 9 is provided between the adapter frame 2 and the second plate 32, and the second limit assembly 9 is used to limit the maximum sliding stroke of the second plate 32.

[0061] In the present embodiment, the structures of the first limit assembly 8 and the second limit assembly 9 are consistent, and the structure of the first limit assembly 8 is taken as an example for explanation below. The first limit assembly 8 includes a first baffle 81 and a first limit switch 82, and the first baffle 81 is arranged on the first plate 31. The first limit switch 82 is arranged on the adapter frame 2, and the first limit switch 82 is electrically connected to the driving member for driving the first plate 31 to slide. The first baffle 81 can trigger the first limit switch 82 when the first plate 31 slides to the maximum stroke, so as to control the driving member for driving the first plate 31 to slide to stop working. It should be noted that the working principle of the first limit switch 82 is the prior art, and the present embodiment does not make any improvements to the first limit switch 82 itself, so it will not be described in detail.

[0062] In order to improve the convenience of assembling the weighing device, the adapter frame 2 and the carrier frame 4 are both formed by assembling a plurality of connecting rods 10 and a plurality of connecting parts 20. Specifically, the plurality of connecting rods 10 include steel structures of different lengths, and the connecting parts 20 include a connecting plate 30 and a connecting bolt 40. The connecting plate 30 is used to connect the ends of a plurality of adjacent connecting rods 10, and the end of each connecting rod 10 is locked on the connecting plate 30 by a connecting bolt 40. With such a configuration, adapter frames 2 and carrier frames 4 of different sizes can be assembled according to different usage scenarios, and the applicability is high. In addition, the plurality of adjacent connecting rods 10 are connected by the connecting plate 30 and the bolts, which has a simple structure and is easy to operate. It should be noted that the length of the connecting plate 30 is designed according to the actual connection requirements, which will not be elaborated in this embodiment.

[0063] This embodiment also provides a crushing production line, which includes a conveyor and the above-mentioned weighing device. The weighing device is arranged on the conveyor, and the weighing device can discharge the weighed materials onto the conveyor belt of the conveyor, and the conveyor belt is used to transport the weighed materials to the next process. Such an arrangement makes it easier to transport materials and helps to improve the production efficiency of the crushing production line. In addition, the crushing production line including the above-mentioned weighing device can timely calculate the weight of large garbage added to the hopper 1, so that the output of the crushing production line can be calculated, and then the output of the crushing production line can be accurately controlled. It should be noted that in this embodiment, the conveyor is selected as a plate chain conveyor belt in the prior art, which will not be described in detail.
