[0002] Transportability refers to the inherent ability of a product or system to be transported by various means of transportation. In industrial production fields such as coal and mining, the materials mined or produced are mainly bulk materials. Bulk materials refer to loose powdered, granular, and block materials, which are mainly transported by belt conveyors. In the actual transportation process, the operating parameters of the belt conveyor are mainly set according to the design standards of the belt conveyor. Due to the differences in specifications, quality and other characteristics of various bulk materials, the transportability under different transportation conditions is also different. The standard setting of the belt conveyor operating parameters is not suitable for the transportation of all bulk materials. For example: the operating parameters of the belt conveyor, such as the operating inclination angle, speed and load capacity, will directly affect the transportability of bulk materials with different characteristics. If the transportability is poor, it will affect the production efficiency of the enterprise. Therefore, the standard setting of the belt conveyor operating parameters is not sufficient to ensure the optimal transportability of bulk materials of different specifications and types.

Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0020] Please see Figure 1 to Figure 2 The utility model embodiment provides a bulk material transport simulation experimental device, including a test belt conveyor 1, a material transfer device 2 and an angle adjustment device 7, wherein the test belt conveyor 1 is arranged on the angle adjustment device 7, and the angle adjustment device 7 can adjust the running inclination of the test belt conveyor 1 to simulate the transportation conditions of different slopes, and the upper end of the feed end of the test belt conveyor 1 is provided with a quantitative feeding device 5, and the quantitative feeding device 5 is used to discharge the bulk material for the experiment to the test belt conveyor 1, and simulate the transportation through the test belt conveyor 1, and the material transfer device 2 is used to adjust the running inclination of the test belt conveyor 1 to simulate the transportation conditions of different slopes ... material transfer device 2 is used to adjust the running inclination of the test belt conveyor 1 to simulate the transportation conditions of different slopes, and the material transfer device 2 is used to adjust the running inclination of the test belt conveyor 1 to simulate the transportation conditions of different slopes, and the material transfer device 2 is used to adjust the running inclination of the test belt conveyor 1 to simulate the transportation conditions of different slopes, and the material transfer device 2 is used to adjust the running inclination of the test belt conveyor 1 to simulate the transportation conditions of different slopes, and the material transfer device 2 is used to adjust the running inclination of the test belt conveyor The material transfer device 2 is arranged on one side of the test belt conveyor 1, adjacent to the test belt conveyor 1, and forms a cross-type inclined arrangement, and the feed end of the material transfer device 2 is arranged below the discharge end of the test belt conveyor 1, and is used to receive the bulk material discharged from the test belt conveyor 1. The discharge end of the material transfer device 2 is directly opposite to the quantitative feeding device 5, so as to input the received bulk material into the quantitative feeding device 5, and the bulk material is discharged to the test belt conveyor 1 again through the quantitative feeding device 5. The material transfer device 2 is mainly used to transfer the bulk material discharged from the test belt conveyor 1, so that the bulk material can be circulated. The ring is used to observe the conveying state of bulk materials of different specifications and types on the test belt conveyor 1. In the simulated conveying process, the bulk materials of the same specifications and types used in the experiment are discharged to the test belt conveyor 1 through the quantitative feeding device 5. The conveying state of the bulk materials of this specification on the test belt conveyor 1 is manually observed, and the running inclination of the test belt conveyor 1 is adjusted through the angle adjustment device 7 to simulate the transportation conditions of different slopes. It is observed whether there is a slippage phenomenon between the bulk materials of this specification and the conveyor belt of the test belt conveyor 1 under the transportation conditions of different slopes. Finally, the test belt conveyor 1 is used to simulate the transportation of bulk materials of different specifications and types separately, and the conveying status of bulk materials of different specifications and types on the test belt conveyor 1 is observed. The maximum inclination angle, belt speed and safe conveying capacity of the test belt conveyor 1 when transporting bulk materials of different specifications and types are determined, and the optimal operating parameters are obtained. By using the operating parameters as a reference standard, the operating parameters of the belt conveyor in actual production can be quickly and accurately set and adjusted, so that the belt conveyor in actual production can quickly reach the optimal operating state and optimal transportation performance, thereby improving transportation efficiency.

[0021] Please see Figures 2 to 4 Specifically, the angle adjustment device 7 includes a base 75 and a supporting cylinder 72. The base 75 is fixed on the ground. The feed end of the test belt conveyor 1 is rotatably mounted on the base 75. The supporting cylinder 72 is vertically hingedly arranged at the lower end of the test belt conveyor 1 and close to the discharge end of the test belt conveyor 1. The test belt conveyor 1 is supported by the base 75 and the supporting cylinder 72. The supporting cylinder 72 is a hydraulic cylinder connected to the output end pipeline of an externally arranged hydraulic pump 74. The supporting cylinder 72 is driven by the hydraulic pump 74 to telescope and adjust the height, so as to raise and lower the height of the discharge end of the test belt conveyor 1, so that the discharge end of the test belt conveyor 1 rotates up and down along the base 75 to adjust the running inclination angle of the test belt conveyor 1.

[0022] The angle adjustment device 7 also includes an angle locator 73 and a base 71. The base 71 is hinged at the lower end of the supporting cylinder 72 to support the bottom of the supporting cylinder 72 to stabilize the supporting cylinder 72. There are two angle locators 73, which are vertically arranged in parallel on both sides of the supporting cylinder 72. The lower end of the angle locator 73 is hinged to the base 71, and the upper end is hinged to both sides of the frame of the test belt conveyor 1. The angle locator 73 can follow the supporting cylinder 72 for height adjustment to provide auxiliary support for the test belt conveyor 1, and is used to position the inclination angle of the test belt conveyor 1 so that the test belt conveyor 1 remains stable during the simulation operation.

[0023] Each of the angle locators 73 includes a stretching inner rod 731, a stretching outer rod 732 and a positioning pin 733. One ends of the stretching inner rod 731 and the stretching outer rod 732 are sleeved and connected to each other to form a telescopic rod. The lower ends of the telescopic rods are hinged to the base 71, and the upper ends of the telescopic rods are hinged to the lower ends of the test belt conveyor 1. When the support cylinder 72 is extended or retracted in height, the stretching inner rod 731 and the stretching outer rod 732 can be relatively telescopic and movable to adaptively adjust the height following the change in the inclination angle of the test belt conveyor 1. The outer wall of the stretching outer rod 732 is transversely provided with positioning holes 734 that penetrate its inner cavity and the side walls on both sides. There are a plurality of positioning holes 734 that are spaced apart along the length direction of the stretching outer rod 732. The positioning pin 733 can be manually inserted into any one of the positioning holes 734. When the support cylinder 72 rises, the stretching inner rod 731 follows the rise of the frame of the test belt conveyor 1. The end of the stretch inner rod 731 inserted in the stretch inner rod 731 will move upward, and the positioning hole 734 at the lower end of the stretch inner rod 731 will open. At this time, the positioning pin 733 can be inserted into the positioning hole 734 of the corresponding height. When the hydraulic cylinder is depressurized and drops, the positioning pin 733 is used to prevent the stretch inner rod 731 from contracting, and the stretch inner rod 731 is limited to position the inclination angle of the test belt conveyor 1. When the support cylinder 72 needs to be lowered, the support cylinder 72 can be extended upward first, and the positioning pin 733 can be manually taken out, and then the support cylinder 72 can be adjusted to descend, and then the positioning pin 733 can be inserted into the positioning hole 734 of the corresponding height. In this way, the running inclination angle of the test belt conveyor 1 is re-positioned, and the test belt conveyor 1 is auxiliary supported by the above-mentioned angle locator 73, which can keep the test belt conveyor 1 stable during the simulation operation and avoid changes in the inclination angle of the test belt conveyor 1 during the simulation operation.

[0024] Please see Figure 1 The material transfer device 2 includes a transfer belt conveyor 21 and a receiving hopper 22. The transfer belt conveyor 21 is arranged on one side of the test belt conveyor 1. The discharge end of the transfer belt conveyor 21 is arranged at the upper end of the quantitative feeding device 5. The receiving hopper 22 is arranged at the feed end of the transfer belt conveyor 21 and is located below the discharge end of the test belt conveyor 1. The receiving hopper 22 is used to receive the bulk material discharged by the test belt conveyor 1, and discharge the received bulk material into the transfer belt conveyor 21. The bulk material is input into the quantitative feeding device 5 through the transfer belt conveyor 21 to complete the recovery of the bulk material.

[0025] Please see Figure 2 and Figure 5Further, the quantitative feeding device 5 includes a feeding hopper 51 and a feeding trough 52. The feeding hopper 51 is set above the feeding end of the test belt conveyor 1. The upper end of the feeding hopper 51 is open. The discharge end of the transfer belt conveyor 21 is located directly above the feeding hopper 51 and can discharge materials into the feeding hopper 51. An elastic hook 53 is provided on the outer wall of the feeding hopper 51. The feeding trough 52 is suspended on the discharge port of the feeding hopper 51 through the elastic hook 53. The discharge end of the feeding trough 52 is directly opposite to the feeding hopper 51. At the feeding end of the test belt conveyor 1, a vibration motor 54 is provided on the feed trough 52, and a chute gate plate 55 and an electric push rod 56 for controlling the discharge amount are provided on the discharge port of the feed hopper 51. The electric push rod 56 is connected to the chute gate plate 55, and can push the chute gate plate 55 to close or open the discharge port of the feed hopper 51. The chute gate plate 55 controls the bulk material in the feed hopper 51 to enter the feed trough 52, and then the vibration motor 54 vibrates to discharge the material, thereby controlling the feed trough 52 to quantitatively feed the test belt conveyor 1.

[0026] When the simulation experiment device is used, the bulk materials for the experiment are loaded into the feeding hopper 51 through an external transfer machine or conveyor, the running inclination angle of the test belt conveyor 1 is adjusted, the test belt conveyor 1 and the transfer belt conveyor 21 are turned on to operate according to the set parameters, and the chute gate 55 is opened to discharge the material to the test belt conveyor 1, so that the bulk materials for the experiment are transported on the test belt conveyor 1, fall into the receiving hopper 22 through the discharge end, and then the material is transferred to the feeding hopper 51 through the transfer belt conveyor 21. Finally, the material is returned to the test belt conveyor 1 through the feeding trough 52 for re-transportation to ensure the continuity of the material on the test belt conveyor 1. During the simulated transportation experiment, the feeding amount of the quantitative feeding device 5, the running speed, inclination angle, starting acceleration, and braking deceleration of the test belt conveyor 1 can all be adjusted to facilitate the experiment of the transportability of bulk materials of different specifications and types under different operating conditions. The above-mentioned transport test process is repeated, and finally the maximum inclination angle, belt speed and safe conveying volume of the test belt conveyor 1 when conveying bulk materials of different specifications and types are determined by observing the conveying status of bulk materials of different specifications and types on the test belt conveyor 1, and the optimal operating parameters are obtained. By using the operating parameters as a reference standard, the operating parameters of the belt conveyor in actual production can be quickly and accurately set and adjusted, so that the belt conveyor in actual production can quickly reach the optimal operating state and optimal transportability, thereby improving transportation efficiency.
