Description

A mobile material receiving and transfer trolley for belt conveyors Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a mobile material receiving and transfer trolley for belt conveyors. Background Technology

[0002] Traditional belt conveyor chutes are fixedly installed at the tail end of the conveyor. A typical chute consists of two side plates, a cover plate, and a rubber belt. The cover plate is bolted to the upper ends of the two side plates, and the lower ends of the side plates are connected to the rubber belt. The chute guides the material to the center of the conveyor belt and ensures it is transported in the direction of travel to the head of the conveyor.

[0003] However, for long belt conveyors, feeding from the tail end of the belt conveyor will greatly increase the material conveying time. If the guide chute can be made movable, then multi-point feeding of the belt conveyor can be achieved, saving conveying time. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a mobile material receiving and transfer trolley for belt conveyors.

[0005] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0006] A mobile receiving and transferring trolley for a belt conveyor is installed on the frame of the belt conveyor. The mobile receiving and transferring trolley includes a trolley frame, a funnel fixed to the top of the trolley frame, and a drive mechanism located at the bottom of the trolley frame for driving the trolley frame to move along the belt travel direction of the belt conveyor. Multiple buffer roller groups are provided below the funnel. The two sides of the buffer roller groups are fixed to the inner wall of the trolley frame by connecting frames. The buffer roller groups are located above the idler groups of the belt conveyor. The distance between two adjacent buffer roller groups is smaller than the distance between two adjacent idler groups of the belt conveyor. The multiple buffer roller groups and the idler groups of the belt conveyor simultaneously support the conveyor belt of the belt conveyor.

[0007] Furthermore, the buffer roller group consists of three buffer rollers. The two ends of the roller shaft of the middle buffer roller are respectively hinged to one end of the roller shaft of the two buffer rollers located at both ends, and the other ends of the roller shaft of the two buffer rollers located at both ends are fixed on the connecting frame.

[0008] Furthermore, the height difference between the buffer idler group and the idler group of the belt conveyor is 200-300mm.

[0009] Furthermore, the distance between two adjacent idler roller groups of the belt conveyor is 1100mm, and the distance between two adjacent buffer idler roller groups is 300mm.

[0010] Furthermore, the drive mechanism includes a track fixed on the frame of the belt conveyor, a bearing seat is provided on the lower bottom surface of the trolley frame, a bearing is installed in the bearing seat, a track wheel is provided on the bearing seat to slide with the track, a rotating shaft is fixedly installed at the center of the track wheel, both ends of the rotating shaft are axially fixed in the inner ring of the bearing, and one end of the rotating shaft extends through one side wall of the bearing seat to the outside of the side wall of the trolley frame; a brake reduction motor is fixedly installed on one side of the bottom of the trolley frame, and the output end of the brake reduction motor is axially fixedly connected to one end of the rotating shaft.

[0011] Compared with the prior art, the material receiving and transfer trolley of this utility model can move actively along the travel direction of the belt conveyor on the frame of the belt conveyor. During the movement of the material receiving and transfer trolley, the buffer idler group below it can support the conveyor belt of the belt conveyor, enabling multi-point feeding of the belt conveyor. In addition, the hinged buffer idler group below the hopper can buffer the material falling into the hopper, thereby protecting the conveyor belt of the belt conveyor on the buffer idler group during feeding.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model.

[0016] As shown in Figures 1 and 2, this embodiment exemplarily illustrates a mobile receiving and transferring trolley for a belt conveyor, installed on the frame 1 of the belt conveyor. The mobile receiving and transferring trolley includes a trolley frame 4, a funnel 5 fixed to the top of the trolley frame 4, and a drive mechanism 8 set at the bottom of the trolley frame 4 for driving the trolley frame 4 to move along the belt travel direction of the belt conveyor. Multiple buffer roller groups 6 are provided below the funnel 5. The two sides of the buffer roller groups 6 are fixed to the inner wall of the trolley frame 4 through connecting frames 7. The buffer roller groups 6 are located above the belt conveyor's roller groups 2. The distance between two adjacent buffer roller groups 6 is smaller than the distance between two adjacent belt conveyor roller groups 2. The multiple buffer roller groups 6 and the belt conveyor's roller groups 2 simultaneously support the conveyor belt 3 of the belt conveyor. The multiple buffer roller groups 6 are used to reduce the impact of falling material on the conveyor belt 3 at the material receiving point of the belt conveyor.

[0017] Specifically, as shown in Figure 1, the buffer roller group 6 consists of three buffer rollers 61 (the roller body of the buffer roller is generally made of rubber buffer ring). The two ends of the roller shaft of the middle buffer roller are respectively hinged to one end of the roller shaft of the two buffer rollers located at both ends, and the other ends of the roller shaft of the two buffer rollers located at both ends are fixed on the connecting frame 7.

[0018] Specifically, as shown in Figure 3, the drive mechanism 8 includes a track 801 fixed on the frame 1 of the belt conveyor. A bearing seat is provided on the lower end face of the bottom of the trolley frame 4. A bearing 802 is installed in the bearing seat. The bearing seat is provided with a track wheel 803 that slides with the track 801. A rotating shaft 804 is fixedly installed at the center of the track wheel 803. Both ends of the rotating shaft 804 are axially fixed in the inner ring of the bearing 802. One end of the rotating shaft 804 extends through one side wall of the bearing seat to the outside of the side wall of the trolley frame 4. A brake reduction motor 805 is fixedly installed on one side of the bottom of the trolley frame 4. The output end of the brake reduction motor 806 is axially fixedly connected to one end of the rotating shaft 804.

[0019] In actual use, the height difference between the buffer idler group 6 and the belt conveyor idler group 2 is 200-300mm. The purpose is to ensure that the buffer idler group 6 will not touch the belt conveyor idler group 2 during movement. The distance between two adjacent idler groups 2 of the belt conveyor is 1100mm, and the distance between two adjacent buffer idler groups 6 is 300mm. As can be seen from Figure 2, the buffer idler groups are denser. As shown in Figure 2, this embodiment exemplarily sets nine buffer idler groups, which is intended to provide better support and buffering for heavier materials and avoid damage to the conveyor belt 3 caused by heavier materials.

[0020] In this embodiment, referring to Figures 1 and 2, when feeding materials onto the belt conveyor, if the belt conveyor is not running, the drive mechanism 8 drives the receiving and transfer trolley to move actively along the travel direction of the belt conveyor on the frame. At this time, the conveyor belt 3 forms an arch-like shape as shown in Figure 1. After moving to the feeding point where materials need to be fed, other feeding equipment (such as a forklift or other belt conveyors) transports the material into the hopper 5. The material can then fall through the hopper 5 onto the conveyor belt 3 below the hopper 5, enabling multi-point feeding of the belt conveyor. In addition, since the buffer roller group 6 below the receiving and transfer trolley can support the conveyor belt 3 of the belt conveyor during the movement of the receiving and transfer trolley, and the hinged buffer roller group 6 below the hopper 5 can buffer the material falling into the hopper 6, thus protecting the conveyor belt 3 of the belt conveyor on the buffer roller group during feeding. After feeding is completed, the belt conveyor can be turned on to transport the material to the end of the belt conveyor. This enables multi-point feeding and saves material transportation time.

[0021] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
