Description

Technical Field

[0001] This utility model relates to a measuring device, specifically a rapid sample measuring scale. Background Technology

[0002] After coal is reduced in size using a reduction device, it can be fed into a rapid testing device for faster results. However, due to differences in coal quality, the bulk density and apparent density of coal vary. Since coal samples are reduced by volume, it is difficult to guarantee sample consistency. Therefore, it is necessary to control the weight of the coal samples during sample preparation to ensure that the weight meets requirements. Currently, weight control is mainly done manually, which leads to reduced testing efficiency and high labor intensity for staff.

[0003] Currently, a utility model patent with publication number CN219121516U discloses a weighing device for coal fuel testing. It includes a fixed base, an mounting plate above the fixed base, and a sample weighing assembly between the fixed base and the mounting plate. The sample weighing assembly includes a placement plate, multiple placement slots, multiple sample tubes, a weighing instrument, and a weighing column. A linkage assembly is provided between the gantry plate and the mounting plate. This coal fuel testing weighing device, through the design of the sample weighing assembly and the linkage assembly, allows several sample tubes to be placed in the placement slots. Through the coordinated operation of the drive motor and the electric telescopic rod, adjacent placement slots move to directly above the weighing column. Then, the placement plate descends and rises again to weigh the sample tubes until all sample tubes in the placement plate have been weighed. This device can quickly weigh multiple sample tubes without manual intervention, greatly avoiding inaccurate weighing.

[0004] As can be seen from the above-disclosed technical content, as existing technology, the utility model with announcement number CN219121516U can quickly realize the weighing of multiple sample tubes without manual operation, which greatly avoids the occurrence of inaccurate weighing. However, this patent mainly weighs pre-packaged sample tubes and cannot be integrated into the coal quality rapid testing device. It also cannot be connected to the reduction device, and cannot quickly weigh and unload materials. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a rapid sample weighing scale that can be directly connected to a coal sample reduction device, which can effectively improve the efficiency of coal sample processing and ensure that the weight of each coal sample meets the requirements.

[0006] To achieve the above objectives, this utility model provides a rapid sample weighing scale, comprising an outer shell. A weighing sensor is fixedly installed inside the outer shell, and a weighing cylinder is fixedly installed on the sensing part of the weighing sensor. The lower end of a discharge plate gate control cylinder is hinged to a base outside the outer shell, and the upper end of the discharge plate gate control cylinder is hinged to a discharge gate control arm. The discharge gate control arm is mounted on the surface of the outer shell via a rotating shaft and a control arm mounting seat, and passes through a pre-set rectangular through hole in the outer shell. A discharge gate is installed on the side of the weighing cylinder facing the discharge gate control arm via a discharge gate rotating shaft. The discharge gate can completely close the discharge port at the bottom of the weighing cylinder. The upper part of the discharge gate is Y-shaped, with one end of the Y-shape connected to the weighing cylinder via a discharge gate return spring, and the other end equipped with a discharge gate control rod. The control arm mounting seat controls the opening and closing of the discharge gate via the discharge gate control rod.

[0007] In addition, the rapid testing sample weighing scale proposed according to the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, flanges are provided at both the upper and lower ends of the outer shell.

[0009] As a further improvement of this utility model, the lower part of the metering cylinder is provided with a rubber skirt.

[0010] As a further improvement of this utility model, the data line port of the metering cylinder is located on the outside of the outer casing.

[0011] As a further improvement of this utility model, the discharge plate gate control cylinder is an electric cylinder.

[0012] By means of the above solution, this utility model has at least the following advantages: compared with conventional manual weight control, the weight of each batch of coal samples is directly determined by the metering cylinder and the weighing sensor, which can be directly connected to the reducing device, effectively improving the coal sample processing efficiency and ensuring that each coal sample meets the design requirements of the rapid testing device.

[0017] The rapid testing sample weighing scale of this utility model is described below with reference to the accompanying drawings.

[0018] In Embodiment 1 of this application, as Figs. 1 to 3 As shown, this rapid testing sample weighing scale (hereinafter referred to as "the present invention") includes an outer shell 1, a discharge plate gate control cylinder 2, a discharge gate control arm 3, a control arm mounting base 4, a weighing cylinder 5, a weighing sensor 6, a discharge gate control rod 7, a discharge gate 8, a discharge gate reset spring 9, a discharge gate rotating shaft 10, and a discharge gate mounting base 11. The upper part of the outer shell 1 is connected to the discharge port of a reducing device, and the discharge port of the reducing device is directly aligned with the upper opening of the weighing cylinder 5 through a funnel. The weighing sensor 6 is fixedly installed inside the outer shell 1, and the weighing cylinder 5 is fixedly installed on the sensing part of the weighing sensor 6. The lower end of the discharge plate gate control cylinder 2 is hinged to the outer shell. On the external base, the upper end of the feeding plate gate control cylinder 2 is hinged to the feeding gate control arm 3. The feeding gate control arm 3 is mounted on the surface of the outer shell 1 through a rotating shaft and a control arm mounting seat 4. The feeding gate control arm 3 passes through a pre-set rectangular through hole in the outer shell 1. The side of the metering cylinder 5 facing the feeding gate control arm 3 is equipped with a feeding gate 8 through the feeding gate rotating shaft 10. The feeding gate 8 can completely close the feeding port at the bottom of the metering cylinder 5. The upper part of the feeding gate 8 is Y-shaped. One end of the Y-shape is connected to the metering cylinder 5 through the feeding gate return spring 9, and the other end is equipped with a feeding gate control rod 7. The control arm mounting seat 4 controls the opening and closing of the feeding gate 8 through the feeding gate control rod 7.

[0019] A weighing device for coal fuel testing (hereinafter referred to as "the patent") with utility model announcement number CN219121516U can quickly weigh multiple sample tubes without manual operation, greatly avoiding inaccurate weighing. However, the patent mainly weighs pre-packaged sample tubes and cannot be integrated into a rapid coal quality testing device. It also cannot be connected to a reduction device, making rapid weighing and unloading impossible. In contrast, this invention uses an outer shell 1 with the upper part directly connected to the outlet of the reduction device. The outlet of the reduction device is directly aligned with the upper opening of the metering cylinder 5 through a funnel. Weighing is performed directly after reduction, achieving rapid weighing and unloading. This can effectively adapt to the production environment and rhythm of coal production or sample preparation lines.

[0020] This embodiment 2 is basically the same in structure as embodiment 1. The difference is that it is convenient to connect the equipment to the discharge port of the reducing device. Flanges are provided at both the upper and lower ends of the outer shell 1.

[0021] To further optimize the working efficiency of this application and to prevent material spillage, the lower part of the metering cylinder 5 is provided with a short and thin rubber skirt that will not obstruct the opening and closing of the discharge gate 8. For ease of wiring connection, the data cable port of the metering cylinder 5 is located outside the outer casing 1. For easy electrical control by the controller, the discharge plate gate control cylinder 2 is an electric cylinder.

[0022] To use the equipment, simply install the rapid testing sample weighing scale and connect it to the corresponding wiring.

[0023] When this utility model is used, its specific operation is as follows:

[0024] In use, the reduced coal sample enters the metering cylinder 5 directly through a funnel or chute. The weighing sensor 6 determines the weight of the coal sample by sensing the total weight of the metering cylinder 5 and its contents. After reaching the set weight, the discharge gate control cylinder 2 extends, pushing the discharge gate control arm 3 to rotate around the pivot of the control arm mounting base 4. This causes the end of the discharge gate control arm 3 located above the discharge gate control rod 7 to press down. The pressed-down discharge gate control arm 3 drives the discharge gate control rod 7 to move down, and the discharge gate control rod 7 drives the discharge gate 8, causing it to... The discharge gate shaft 10 rotates around its axis, thereby opening the discharge gate 8 of the metering cylinder 5. When the discharge gate 8 opens, the discharge gate return spring 9 enters the stretched state. At this time, the material falls into the sample tank or conveyor belt under the action of gravity, and can then be transported to the rapid testing device for testing. Then, the discharge plate gate control cylinder 2 retracts, driving the discharge gate control arm 3 to reset. After the discharge gate control rod 7 loses pressure, the discharge gate 8 resets under the action of the discharge gate return spring 9, re-closing the metering cylinder 5, waiting for the next weighing.

[0025] In summary, the rapid testing sample weighing scale of this utility model embodiment directly determines the weight of each batch of coal samples through the weighing cylinder 5 and the weighing sensor 6. It can be directly connected to the reducing device, which can effectively improve the coal sample processing efficiency and ensure that each coal sample meets the design requirements of the rapid testing device.
