Description

Technical Field

[0001] This utility model belongs to the field of material loading technology, and specifically relates to a quantitative loading device. Background Technology

[0002] Currently, the transportation of bulk materials is mainly achieved through railways, highways, and waterways. How to quantitatively and efficiently load bulk materials into train and truck carriages 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 bulky loading equipment. This not only prolongs 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, the rotary three-bucket loading equipment was developed. It eliminates the bulky receiving buffer bin, which largely solves the problem of the large size of the loading equipment. However, it requires the addition of a rotating mechanism to drive the rotation of the bin and the material inside. The rotating mechanism is not only complex in terms of force and structure, but also has poor reliability in operation. It has high requirements for the speed regulation and control of the feeding belt, and has high manufacturing cost and energy consumption. It is also difficult to adapt to the changes in vehicle speed and material volume during the complex loading process of trains and trucks. Furthermore, in the rotary three-bucket loading equipment, since the material is in dynamic rotation, its weighing method is rotational dynamic metering, which leads to poor metering accuracy.

[0031] 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.

[0032] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0033] One embodiment of this utility model provides a quantitative loading device, such as... Figure 1 and Figure 2 As shown, the quantitative loading device includes a material distribution mechanism, a quantitative weighing mechanism, and a material loading mechanism arranged sequentially from top to bottom.

[0034] Specifically, the quantitative weighing mechanism includes a support frame (not shown in the figure) and four hoppers 1 arranged in a grid pattern. The four hoppers 1 take turns receiving, buffering, unloading, and weighing, providing a larger material buffering capacity and eliminating the need for a separate receiving and buffering hopper. The four hoppers 1 are fixed on the support frame, and each hopper 1 has a discharge port at its bottom with a discharge gate 2. The discharge gate 2 can be adjusted to achieve precise discharge. Each hopper 1 has a weighing sensor 3 on its outer peripheral wall. The weighing sensor 3 is used to measure the mass of the material in the hopper 1, realizing static metering and integrated buffering and weighing functions. Compared with dynamic metering, the metering accuracy is higher. Preferably, each hopper 1 is equipped with four weighing sensors 3 to ensure the metering accuracy of the material. Each hopper has a maximum capacity of 45t. A single hopper can meet the loading needs of a container (32t), and two hoppers can meet the loading needs of all existing train carriages (60t~80t).

[0035] Furthermore, the material distribution mechanism is used to receive the material conveyed by the feeding belt 4 and distribute the material to the four hoppers 1. That is, the feeding belt 4 conveys the material to the material distribution mechanism, and then the material distribution mechanism conveys the material to the corresponding hopper 1 as needed. There is no need to set up a rotating structure to drive the hopper 1 to rotate, so that the hopper 1 can enter different working states in turn. The material collection and loading mechanism is used to guide the material released from each hopper 1 to the loading position, such as guiding it to the train car 23.

[0036] In summary, the quantitative loading device of this embodiment, by setting up four hoppers arranged in a grid pattern and installing weighing sensors on each hopper, not only achieves integrated buffering and weighing but also improves the material buffering capacity. Furthermore, by setting up a material distribution mechanism and directly fixing the four hoppers to the support frame, the rotational movement of large-tonnage hoppers is avoided, and there is no need to set up a huge receiving buffer hopper, thereby reducing the manufacturing cost and energy consumption of the loading device. It can achieve fixed static metering of materials, effectively improve metering accuracy, and is more adaptable to changes in speed during train and truck loading, resulting in higher operational reliability.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the horizontal cross-section of hopper 1 is square, and the lower outer surface of hopper 1 is an inclined surface that approaches the center of the grid shape. This means that four hoppers 1 can be assembled into a square trapezoid, allowing materials to be collected and loaded into the material collection mechanism. Of course, the horizontal cross-section of the hopper can also be rectangular or semi-circular, which is also within the scope of this invention. When the horizontal cross-section of the hopper is semi-circular, the four hoppers can be assembled into a circular trapezoid.

[0038] In this embodiment, as Figure 3 and Figure 5 As shown, the fabric mechanism includes a circular fabric trough 5, a rotating ring 6, a first drive assembly, and a second drive assembly.

[0039] A rotating ring 6 is located inside the material trough 5 and is coaxially aligned with it. The rotating ring 6 and the material trough 5 can rotate relative to each other. Multiple scrapers 7 are provided on the outer circumference of the rotating ring 6, each scraper 7 extending radially along the rotating ring 6 and having reinforcing ribs. A first drive assembly drives the rotating ring 6 to rotate. To increase the structural strength of the rotating ring 6, multiple reinforcing ribs are provided on its inner circumference. A discharge port 8 is opened at the bottom of one side of the material trough 5. A second drive assembly drives the material trough 5 to rotate. Material falls into the material trough 5 from the feeding belt 4. The second drive assembly drives the material trough 5 to rotate to the desired angle. Then, the first drive assembly drives the rotating ring 6 to rotate, which in turn moves the scrapers 7. The scrapers 7 push the material in the material trough 5 to the discharge port 8, allowing the material to be discharged at a specified angle, which can be arbitrarily controlled.

[0040] Furthermore, the bottom of each scraper is toothed or wavy, which reduces friction between the scraper and the bottom of the fabric trough, thus extending the equipment's lifespan.

[0041] In addition, such as Figure 3 and Figure 4 As shown, a circular opening is formed on the bottom of the fabric trough 5 at its center. The lower part of the rotating ring 6 protrudes through the circular opening and is connected to the first drive assembly below the fabric trough 5. The second drive rod assembly is located below the fabric trough 5, making the structure of the fabric mechanism more compact and occupying less space. An annular seal 9 is provided between the fabric trough 5 and the rotating ring 6 to prevent material from entering between the fabric trough 5 and the rotating ring 6 and affecting the stable operation of the first drive assembly and the second drive assembly.

[0042] Furthermore, such as Figure 3 and Figure 6 As shown, the first drive assembly includes a first motor 10, a first reducer 11, a first gear 12, and an annular internal gear 13; the output shaft of the first motor 10 is fixedly connected to the input shaft of the first reducer 11, the output shaft of the first reducer 11 is fixedly connected to the first gear 12, the first reducer 11 is used to increase the output torque of the first motor 10, the first gear 12 meshes with the annular internal gear 13, and the annular internal gear 13 is fixedly connected to the rotating ring 6, specifically by bolt connection.

[0043] The second drive assembly includes a second motor 14, a second reducer 15, a second gear 16, and an annular external gear 17. The output shaft of the second motor 14 is fixedly connected to the input shaft of the second reducer 15, and the output shaft of the second reducer 15 is fixedly connected to the second gear 16. The second reducer 15 is used to increase the output torque of the second motor 14. The second gear 16 meshes with the annular external gear 17, which is fixedly connected to the fabric trough 5, specifically via bolts. Two of each of the second motor 14, second reducer 15, and second gear 16 can be provided, thereby increasing the driving force when the fabric trough 5 rotates.

[0044] The annular external tooth 17 is fitted on the outside of the annular internal tooth 13, and a rotary bearing 18 is provided between the annular external tooth 17 and the annular internal tooth 13, thereby realizing the relative rotation of the annular external tooth 17 and the annular internal tooth 13.

[0045] In other embodiments, the fabric feeding mechanism includes an annular fabric feeding trough, an annular curved belt, a first drive assembly, and a second drive assembly. The curved belt is disposed at the bottom of the fabric feeding trough and can rotate within it. The first drive assembly drives the curved belt to rotate. A discharge port is formed on one side of the fabric feeding trough wall, and an inclined baffle is provided downstream of the discharge port. When the curved belt carries material and rotates within the fabric feeding trough, the baffle guides the material to the discharge port, thus discharging the material into the hopper. The second drive assembly drives the fabric feeding trough to rotate. Alternatively, the curved belt can be replaced with stacked blades.

[0046] In this embodiment, as Figure 3 As shown, the fabric mechanism also includes a top cover 19.

[0047] The top cover 19 covers the opening of the fabric trough 5 to seal the top of the fabric trough 5. The top cover 19 has a feed inlet 20, which is located below the feeding belt 4.

[0048] And, as Figure 1 As shown, the aggregate loading mechanism includes an aggregate chute 21 and a loading chute 22.

[0049] The collecting chute 21 is funnel-shaped and located below each hopper 1, used to receive the material discharged from each hopper 1. The loading chute 22 is located below the collecting chute 21 and is used to guide the material discharged from the collecting chute 21 to the loading position. The lower part of the loading chute 22 can be extended and retracted horizontally or oscillatedly to meet different loading needs. For example, the lower part of the loading chute 22 is a corrugated pipe structure, and the lower part of the loading chute 22 is driven to extend and retract vertically by a drive cylinder, and the lower part of the loading chute 22 is driven to translate or oscillate by a motor and a gear and rack structure.

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.
