Description

Technical Field

[0001] This utility model belongs to the technical field of concrete mixing equipment, specifically relating to a novel mobile belt conveyor material distribution system. Background Technology

[0002] As a core facility in modern construction, concrete mixing plants need to store various types of aggregates in their silos, such as coarse aggregates, fine aggregates, and sand and gravel of different particle sizes. With the expansion of project scale, the silo area increases, and the types of aggregates increase, the existing concrete placement system cannot meet the requirements in terms of placement efficiency, coverage, and automation.

[0003] Traditional concrete placement systems typically employ fixed or unidirectional moving belt conveyors for aggregate transport. Fixed belt conveyors, due to their fixed location, limit the placement range and easily create dead zones within the hopper, leading to uneven aggregate accumulation. This necessitates frequent manual adjustments or secondary transfers using loaders, increasing energy consumption and reducing operational efficiency. While unidirectional moving belt conveyors can expand the placement range through horizontal movement, their single direction of movement still requires manual adjustment of the drop point, making multi-directional precise placement difficult. Furthermore, existing belt conveyor systems often experience aggregate mixing and contamination when switching between different aggregate types due to overlapping placement paths, affecting the accuracy of concrete mix proportions.

[0004] Therefore, there is an urgent need to develop a new type of mobile belt conveyor system that can achieve multi-directional automated material distribution, eliminate dead corners in the hopper, improve space utilization and material distribution accuracy, in order to solve the above-mentioned technical problems.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-2 As shown, a novel mobile belt conveyor material distribution system includes a frame 8, which serves as a supporting skeleton to bear various components, ensuring the overall stability and structural strength of the equipment. The frame 8 adopts a modular design for easy transportation and on-site assembly; its rigid structure can resist vibration and load impact during the material distribution process. A main belt conveyor 3 is installed on the top of the frame 8, which is responsible for conveying the aggregate in the receiving hopper 2 from the inlet end to the outlet end, forming the main channel for aggregate conveying.

[0023] A receiving hopper 2 is installed at one end of the main belt conveyor 3. The receiving hopper 2 receives aggregate from the feeding belt conveyor 1 and evenly conveys the material to the main belt conveyor 3 through a guide structure to prevent accumulation or blockage. The feeding belt conveyor 1 is installed on one side of the receiving hopper 2, and a bidirectional belt conveyor 6 is installed at the other end of the main belt conveyor 3. The bidirectional belt conveyor 6 receives aggregate conveyed by the main belt conveyor 3 and achieves bidirectional material distribution by switching between forward and reverse rotation.

[0024] A truss beam 5 is mounted on the frame 8. The truss beam 5 serves as the support rail for the bidirectional belt conveyor 6 and the moving trolley 4, providing a movement path and bearing the operating load of the equipment. The bidirectional belt conveyor 6 is mounted on the truss beam 5, and a traveling device 7 is directly connected between the bidirectional belt conveyor 6 and the truss beam 5. The traveling device 7 drives the bidirectional belt conveyor 6 to move along the longitudinal track of the truss beam 5, adjusting the material placement point and achieving smooth, low-noise mechanical transmission. The moving trolley 4 is mounted on the truss beam 5, and the moving trolley 4 is integrated with the truss beam 5, driving the bidirectional belt conveyor 6 to move laterally.

[0025] The specific design of the aforementioned key components will be discussed in detail below:

[0026] The traveling device 7 includes a drive motor, a transmission gear set, and a track wheel system. The track wheel system moves along the longitudinal track of the truss beam 5, and the drive motor is connected to the bidirectional belt conveyor 6 through the transmission gear set. The drive motor is a high-torque servo motor with a rated power of 5.5kW, and its speed is controlled by a frequency converter to meet the load requirements of the bidirectional belt conveyor 6.

[0027] The transmission gear set adopts a helical gear reduction mechanism. The gear material is 20CrMnTi, carburized and quenched, with a tooth surface hardness of HRC58-62, ensuring smooth transmission and wear resistance. The track wheels are made of polyurethane-coated steel core and roll along the H-shaped steel tracks on both sides of the truss beam 5. The track surface is galvanized for rust prevention, and the wheel system is equipped with a spring buffer device to reduce the impact of movement.

[0028] The output shaft of the drive motor is connected to the input shaft of the gear set via a coupling. The output shaft of the gear set drives the track wheel shaft, forming a power chain of "motor → gear set → track wheel".

[0029] The bidirectional belt conveyor 6 is equipped with a forward / reverse adjustment button. The button is integrated into the PLC control panel and controls the power supply phase of the motor of the bidirectional belt conveyor 6 via a relay to achieve forward / reverse switching. Before switching between forward and reverse, the electromagnetic brake is automatically triggered. The direction switch is performed only after the belt has completely stopped to prevent mechanical impact. The forward / reverse adjustment button has LED indicator lights, such as green for forward rotation and red for reverse rotation. The panel simultaneously displays the belt's running direction and speed.

[0030] The mobile trolley 4 and the truss beam 5 form an integrated mobile mechanism. The base of the mobile trolley 4 is rigidly connected to the truss beam 5 by high-strength bolts. The trolley body adopts a box-type welded structure. Four sets of servo drive wheels are installed at the bottom of the trolley: two active wheels and two driven wheels. The active wheels are equipped with absolute encoders and communicate with the PLC via a CAN bus to achieve closed-loop position control.

[0031] The main conveyor belt 3 and the bidirectional conveyor belt 6 are arranged orthogonally, and a diversion guide chute is provided at the vertical intersection of the main conveyor belt 3 and the bidirectional conveyor belt 6. The main conveyor belt 3 is arranged horizontally, and the bidirectional conveyor belt 6 is vertically mounted at the end of the main conveyor belt 3. The material on the main conveyor belt 3 slides naturally into the bidirectional conveyor belt 6 through the guide chute.

[0032] The truss beam 5 adopts a telescopic sleeve structure, comprising at least three telescopic segments, each with an independent locking device. The truss beam 5 consists of three rectangular steel pipe sleeves, with a base section of 500×300mm. The telescopic section section decreases by 50mm at each stage, with a single-stage telescopic stroke of 4m and a total extended length of 12m. Each segment is equipped with a hydraulic pin lock at its end; the pin has a diameter of 40mm and is inserted into a pre-drilled hole in the truss beam 5 for fixation. The telescopic movement is driven by a hydraulic cylinder, which is linked to a PLC, supporting remote control operation.

[0033] The main belt conveyor 3 and the bidirectional belt conveyor 6 are equipped with a hydraulic automatic tension adjustment mechanism and a real-time tension monitoring module. A double-acting hydraulic cylinder is used, and the tension is controlled by a proportional valve. An accumulator is installed in the oil circuit to buffer pressure fluctuations. A cantilevered tension sensor is installed under the belt, and real-time data is uploaded to the PLC to form a closed-loop control with the hydraulic system. When the tension exceeds the set range of ±10%, the PLC automatically stops the machine and issues an alarm to prevent belt breakage or slippage.
