Description

Technical Field

[0001] The invention relates to a material conveying device and a material conveying system. Background Art

[0002] Storing industrial raw materials has always been a challenge in many industries, including mining, electricity, metallurgy, chemicals, and building materials. Currently, industrial raw materials are primarily stored in greenhouses or outdoors. Both methods require a material yard, where transport vehicles deposit the raw materials. Forklifts and other machinery then transport the raw materials to silos. To prevent dust pollution from forklifts and other machinery, existing technologies typically use material yard conveyors to transport the materials to the corresponding silos.

[0003] Currently, material yard conveyors consist of a conveyor track with rollers mounted on it, and a conveyor belt wound around the rollers. Furthermore, a movable chassis is mounted on the conveyor track, which arches the conveyor belt during movement to change the position of the conveyor belt's drop point. Because this type of material yard conveying often uses linear conveying, with materials dropping in the front-to-back direction of the silo, it can easily cause the material to form a large accumulation angle within the silo, resulting in a partial waste of storage space and low space utilization. Summary of the Invention

[0004] The object of the present invention is to provide a material conveying device to solve the technical problem of low space utilization rate in the silo when conveying materials in the existing material conveying device; the object of the present invention is also to provide a material conveying system that can improve the space utilization rate of the silo.

[0005] To achieve the above-mentioned purpose, the technical solution of the material conveying device provided by the present invention is:

[0006] The material conveying device includes:

[0007] The main conveying mechanism is used to be installed on the top of the silo, and includes a conveying frame, a main conveyor belt installed on the conveying frame, and a mobile chassis configured to move back and forth on the conveying frame. The mobile chassis arches the main conveyor belt to different positions during the forward and backward movement to change the drop point of the main conveying mechanism;

[0008] The rotating platform is used to move synchronously with the mobile chassis in the front and rear directions;

[0009] The belt-type auxiliary conveying mechanism is assembled on the rotating platform and rotates with the rotating platform to change the drop position of the auxiliary conveyor belt. It includes an auxiliary conveyor belt. During the process of conveying materials, a part of the auxiliary conveyor belt is always below the drop point of the main conveying mechanism to receive materials.

[0010] Beneficial effects: The mobile chassis in the material conveying device can move in the front-to-back direction. During the front-to-back movement of the mobile chassis, the rotating platform moves synchronously with the mobile chassis, and the belt-type auxiliary conveying mechanism is assembled on the rotating platform. That is, when the material on the main conveying mechanism falls on the auxiliary conveyor belt, the auxiliary conveyor belt can drop the material at different positions in the front-to-back direction of the silo. In addition, since the rotating platform can rotate, the belt-type auxiliary conveying mechanism can rotate with the rotating platform, so that the auxiliary conveyor belt can drop the material into the silo at different positions within its rotation range. This material conveying device can not only drop the material at various positions in the front-to-back direction of the silo, but also drop the material at different positions within the silo within the rotation range of the auxiliary conveyor belt. Compared with the existing technology, the dropping range is greatly improved. During the material conveying process, the stacking angle formed by the accumulation of materials can be reduced, thereby improving the space utilization rate within the silo.

[0011] Furthermore, the rotating platform is assembled on the moving chassis so that the moving chassis drives the rotating platform to move back and forth in the front-rear direction.

[0012] Beneficial effects: The mechanical principle is adopted to realize the synchronous movement of the rotating platform and the mobile chassis, and no additional control device and drive device are required, and the structure is simple.

[0013] Furthermore, one end of the belt-type auxiliary conveying mechanism is close to the rotating platform, and the other end is arranged away from the rotating platform, wherein the end arranged away from the rotating platform is a drop end for materials to fall.

[0014] Beneficial effects: the drop end of the belt-type auxiliary conveying mechanism is determined, and the material can only fall from the drop end of the belt-type auxiliary conveying mechanism, without the need to additionally set up a device for enabling the auxiliary conveying belt to transport in both directions, and the structure is simple.

[0015] Furthermore, the position of the material drop point of the main conveying mechanism is always on the rotation axis of the rotating platform.

[0016] Beneficial effect: no matter how much the rotating platform rotates, it can be ensured that when the belt-type auxiliary conveying mechanism rotates with the rotating platform, the auxiliary conveying belt thereon can always be connected to the material.

It includes an auxiliary conveyor belt. During the process of conveying materials, a part of the auxiliary conveyor belt is always below the drop point of the main conveying mechanism to receive materials.

[0022] Beneficial effects: The mobile chassis in the material conveying system can move in the front-to-back direction. During the front-to-back movement of the mobile chassis, the rotating platform moves synchronously with the mobile chassis, and the belt-type auxiliary conveying mechanism is assembled on the rotating platform. That is, when the material on the main conveying mechanism falls on the auxiliary conveyor belt, the auxiliary conveyor belt can drop the material at different positions in the front-to-back direction of the silo; in addition, since the rotating platform can rotate, the belt-type auxiliary conveying mechanism can rotate with the rotating platform, so that the auxiliary conveyor belt can drop the material into the silo at different positions within its rotation range.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0034] Specific embodiments of the material conveying device of the present invention:

[0035] The material conveying device includes a main conveying mechanism and a belt-type auxiliary conveying mechanism, such as Figure 1 、 Figure 2 ,and Figure 3 As shown, the main conveying mechanism includes a conveyor frame 11 for fixing on the top of the silo, and a main conveying track 10 extending in the front-to-back direction is provided on the conveyor frame 11. The two ends of the main conveying track 10 are respectively provided with a first roller 3 and a fourth roller 6. The first roller 3 and the fourth roller 6 are wound around the main conveyor belt 2 for conveying materials. The main conveying track 10 is also provided with a plurality of support rollers 8 arranged at intervals along its extension direction to support and convey the main conveyor belt 2.

[0036] The main conveyor mechanism also includes a mobile chassis 1 that is movably mounted on the main conveyor track 10. The mobile chassis 1 comprises a chassis and a support frame 7 secured to the chassis. As the mobile chassis 1 reciprocates in the forward and backward directions, the support frame 7 arches the main conveyor belt 2. Specifically, the support frame 7 is equipped with a third roller 5, and the chassis is equipped with a second roller 4. The third roller 5 is located diagonally above the second roller 4, and the main conveyor belt 2 is wound around the third and second rollers 5 and 4. The support frame 7 divides the main conveyor belt 2 into a horizontal conveying section, an inclined conveying section 19, and a Z-shaped conveying section 18. The horizontal conveying section includes a horizontal conveying section on the main conveyor track 10 and a horizontal conveying section located at the top of the support frame 7. The third roller 5 and the second roller 4 are located at the upper and lower sides of the Z-shaped conveying section 18, respectively. A hopper 9 is located at the head of the mobile chassis 1. The hopper 9 has a material drop channel. Directly below the drop channel is the material drop point of the main conveyor mechanism. From the third roller 5 to the second roller 4, the conveying angle of the main conveyor belt 2 changes, and the material located above the support frame 7 can directly fall into the hopper 9 through the third roller 5 without continuing to be conveyed along the "Z"-shaped conveying section 18.

[0037] The material conveying device also includes a rotatable rotating platform, such as Figure 2 As shown, the rotating platform includes a base 12 fixedly connected to the head of the mobile chassis 1 and a turntable 25 rotatably mounted on the base 12. The base 12 is provided with an annular groove along which the turntable 25 can rotate. A motor is mounted on the base 12. The motor is a variable frequency motor with adjustable output shaft speed. The turntable 25 is provided with a planetary reduction mechanism 24, which is in transmission connection with the motor. The motor output shaft 13 is connected to the sun gear of the planetary reduction mechanism 24. The planetary carrier of the planetary reduction mechanism 24 is fixed, and the ring gear is fixed to the turntable 25. When the motor rotates, it drives the sun gear, which in turn transfers power to the planetary gears. The planetary gears then transfer power to the ring gear. When the ring gear rotates, it drives the turntable 25 to achieve speed reduction.

[0038] The motor output shaft 13 is located at the center of the base 12. The main conveyor mechanism's drop point is always located on the rotating platform's axis of rotation, i.e., the axis of the motor output shaft 13. A bearing 26 is mounted along the motor output shaft 13 along its axial direction. A bearing seat 14 is mounted on the outside of the bearing 26 and is screwed to the top of the base 12.

[0039] One end of the belt-type auxiliary conveying mechanism is close to the rotating platform, and the other end is set away from the rotating platform, wherein the end set away from the rotating platform is a drop-off end for materials to fall. Specifically, the belt-type auxiliary conveying mechanism includes an auxiliary frame fixed to the motor output shaft 13, the auxiliary frame includes a bracket for supporting the auxiliary conveying belt and a fixed frame 23 at the bottom of the bracket, the fixed frame 23 is fixedly connected to the turntable 25, and when the turntable 25 rotates, it drives the fixed frame 23 to rotate, thereby achieving decelerated output. The bracket includes a diagonal brace 22 set in the circumferential direction of the fixed frame 23 and an auxiliary conveying track 17 connected to the end of the diagonal brace 22 away from the fixed frame 23. The auxiliary conveying track 17 is provided with a fifth roller 15 and a sixth roller 16, and an auxiliary conveying belt 20 is wound around the fifth roller 15 and the sixth roller 16. The fifth roller 15 is set close to the rotating platform, and the sixth roller 16 is set away from the rotating platform. The sixth roller 16 forms the drop-off end of the belt-type auxiliary conveying mechanism.

[0040] When the conveying device is working, it can be divided into the following situations:

[0041] Case 1: Mobile chassis 1 is stationary, and motor output shaft 13 is not rotating. The material first falls into the horizontal conveying section of main conveyor track 10, is transported via inclined conveying section 19 to the horizontal conveying section of support frame 7, then passes through third roller 5 and directly into hopper 9. From there, it falls through the hopper's drop channel onto auxiliary conveyor belt 20, and finally passes through sixth roller 16 into silo 21.

[0042] Case 2: The mobile chassis 1 moves forward and backward, and the motor output shaft 13 does not rotate. At this time, the mobile chassis 1 drives the rotating platform to move forward and backward, which can change the position of the drop point of the auxiliary conveyor belt 20 in the front and rear direction of the silo.

[0043] Case 3: The mobile chassis 1 is stationary, and the motor output shaft 13 rotates. The motor output shaft 13 drives the auxiliary conveyor belt 20 to rotate. The auxiliary conveyor belt 20 runs in an arc. The material on the auxiliary conveyor belt 20 can fall at any position within the rotation range of the auxiliary conveyor belt 20.

[0044] Case 4: The mobile chassis 1 moves forward and backward, and the motor output shaft 13 rotates. At this time, the auxiliary conveyor belt 20 can drop materials at different positions in the front-to-back direction of the silo, and at different positions within the rotation range of the auxiliary conveyor belt 20, greatly expanding the drop range.

[0045] The material conveying device can drop materials evenly in the silo, reduce the stacking angle formed by material accumulation, improve the space utilization rate of the silo, and at the same time reduce the construction height of the silo accordingly, saving the construction cost of the silo.

[0046] In the above embodiment, the rotating platform is fixed on the mobile chassis. In other embodiments, the rotating platform may not be fixed on the mobile chassis. In this case, the rotating platform can be mechanically connected to the mobile chassis to achieve synchronous movement of the two. Alternatively, an additional moving device that can move along the conveying direction of the main conveyor belt and can fix the rotating platform can be provided, and the moving speeds of the mobile chassis and the moving device can be controlled respectively by corresponding controllers and drive devices to achieve synchronous movement of the two.

[0047] In the above embodiment, one end of the belt-type auxiliary conveyor mechanism is located near the rotating platform, while the other end is located away from the rotating platform. The end located away from the rotating platform serves as a drop-off end for materials to fall. In other embodiments, the belt-type auxiliary conveyor mechanism may be symmetrically arranged about the rotating platform's axis of rotation, in which case both ends of the belt-type auxiliary conveyor mechanism may serve as drop-off ends.

[0048] In the above embodiment, the position of the drop point of the main conveying mechanism is always on the rotation axis of the rotating platform. In other embodiments, the position of the drop point of the main conveying mechanism may not be on the rotation axis of the rotating platform. For example, a drop plate can be installed on the auxiliary conveyor belt. The drop plate has a flared structure. When in use, the drop plate can always be below the drop point of the main conveying mechanism.

[0049] In the above embodiment, the belt-type auxiliary conveying mechanism reduces its own rotational speed through a planetary reduction mechanism. In other embodiments, a reduction gear system may be connected to the motor output shaft to reduce the rotational speed of the belt-type auxiliary conveying mechanism.

[0050] Specific embodiments of the material conveying system provided by the present invention:

[0051] The material conveying system includes a silo for storing materials and a material conveying device for conveying materials into the silo. The structure of the material conveying device is the same as that of the material conveying device in the above embodiment and will not be repeated here.
