[0002] At present, all concrete mixing plants need to be equipped with feeding facilities. Through the feeding facilities, a variety of different raw materials are discharged from different unloading bins into the distribution belt in turn, and then the distribution belt unloads various materials into corresponding feeding bins respectively. At the same time, in order to facilitate the subsequent metering and batching of materials, different materials need to be stored in different feeding bins. In order to complete the unloading, a discharging trolley needs to be set on the distribution belt. At the same time, multiple feeding bins are arranged under the distribution belt. The discharging trolley moves to the top of the feeding bin corresponding to the material currently transported on the distribution belt to complete the unloading of various materials in turn.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-5 The specific implementation modes of the present utility model are further described in detail.

[0025] When the utility model is actually used, Figure 1-5, a high-efficiency belt conveyor material distribution system, comprising at least one unloading bin 1, referring to the attached drawings, in actual scenarios, due to the need to coordinate and measure the raw materials, the truck transporting the raw materials will unload the raw materials into the unloading bin 1, and at the same time, unloading bins 1 for storing different raw materials are respectively provided according to the types of different raw materials required, that is, the number of unloading bins 1 is determined by the type of raw materials, and an inclined belt conveyor 2 is provided below the unloading bin 1, that is, the raw materials discharged through the unloading bin 1 directly fall onto the inclined belt conveyor 2. It should be mentioned that the different belt conveyors mentioned in this embodiment are all commonly used types of conveying devices, and those skilled in the art can select them according to actual needs to meet the requirements of stable transportation of materials. The inclined belt conveyor The conveyor 2 cooperates with the final belt conveyor 3 to transfer materials, that is, the raw materials transported on the inclined belt conveyor 2 will eventually fall onto the final belt conveyor 3. By default, a transfer belt conveyor 10 is allowed to be set between the inclined belt conveyor 2 and the final belt conveyor 3, so as to reasonably transport the raw materials according to the scene needs. In this embodiment, a control host is also included, and the control host is used to control the replenishment of the required raw materials in the system. By default, a discharge door 9 is provided under each of the lower bins 1, and the discharge door 9 is electrically connected to the control host. In this embodiment, the discharge door 9 adopts the discharge structure commonly used in the field. The specific discharge door 9 structure is not specifically described in this embodiment, and it satisfies the control by the control host. The driving device of the unloading structure realizes the unloading of all the lower material bins 1 by controlling the host computer. It is preset that a material door opening and closing detection sensor electrically connected to the host computer is provided at the unloading door 9, so that the specific state of the unloading door 9 is detected by the material door opening and closing detection sensor. It is preset that in this embodiment, the raw materials transported to the last belt conveyor 3 need to be unloaded into a dedicated storage bin 4. Specifically, at least one storage bin 4 is arranged under the last belt conveyor 3. It is preset that the number of the storage bins 4 is the same as or more than the number of the lower material bins 1, so as to ensure that only one kind of raw material is contained in one storage bin 4. At the same time, when a certain kind of raw material is required in large quantities, in order to facilitate storage, multiple storage bins 4 are allowed to store one kind of raw material at the same time, but each storage bin 4 Only a single raw material can be stored, and multiple raw materials are not allowed to be discharged into the same storage bin 4, so as to facilitate the metering of raw materials in the storage bin 4, and to achieve metering of different raw materials from the storage bin 4 into the mixing host for mixing according to the mixing ratio. It is preset that in this embodiment, in order to reduce the floor space of the entire material distribution system, the unloading bin 1 needs to be arranged in sequence above the inclined belt conveyor 2 when multiple are provided, and the storage bin 4 is arranged in sequence below the last belt conveyor when multiple are provided. In order to facilitate the discharge of raw materials from the last belt conveyor 3 into the storage bin 4, the last belt conveyor 3 is provided with a discharge vehicle 5, which satisfies the requirement of discharging materials from the last belt conveyor 3 into each storage bin 4 through the discharge vehicle 5;

[0026] In this embodiment, a high-position belt conveyor 6 is arranged above the last belt conveyor 3, and a discharge vehicle 5 is arranged on the high-position belt conveyor 6. The discharge vehicle 5 arranged on the high-position belt conveyor 6 is consistent with the discharge vehicle 5 arranged on the last belt conveyor 3. In this embodiment, rollers 11 are arranged at the bottom of the discharge vehicle 5, and the rollers 11 cooperate with the tracks 12 laid on the last belt conveyor 3 and the high-position belt conveyor 6 to realize the walking of the discharge vehicle 5. At the same time, in this embodiment, the discharge vehicle 5 A material blocking conveyor belt 13 is provided on the top for intercepting and conveying the materials on the end belt conveyor and the high-position belt conveyor 6. The end of the material blocking conveyor belt 13 is matched with a discharge hopper 14 provided on the discharge vehicle 5. Specifically, the material blocking conveyor belt 13 on the discharge vehicle 5 is in contact with the belt surfaces of the end belt conveyor 3 and the high-position belt conveyor 6, so that the raw materials on the belt will be transported to the discharge hopper 14 on the discharge vehicle 5 through the material blocking conveyor belt 13, and then the raw materials will be guided and discharged into the storage bin 4 through the discharge hopper 14;

[0027] In this embodiment, when the material distribution system used is a single-ended belt conveyor, the unloading vehicle 5 needs to move up and down in different storage bins 4 when unloading the raw materials. However, whether each raw material needs to be replenished is random and needs to be determined based on the remaining raw materials in the storage bin 4. Therefore, after the unloading vehicle 5 has unloaded a certain raw material, the storage bin 4 where the next raw material needs to be unloaded is far away from the location of the unloading vehicle 5 at this time, and the unloading vehicle 5 needs to move for a long time. At the same time, in the material distribution system, in order to ensure that multiple raw materials are not mixed, it is necessary to ensure that a certain raw material is replenished after it is completely unloaded. , the unloading door 9 of the next unloading bin 1 opens to discharge the materials, and the opening of this material door needs to be determined according to the position of the unloading bin 1 moving to the storage bin 4 where the materials need to be added. In this embodiment, the moving speed of the unloading vehicle 5 is constant. Then, in this system, after a certain time has passed since the unloading door 9 of the previous unloading bin 1 was closed, the unloading door 9 of the next unloading bin 1 will automatically open to discharge the next material. At the same time, the time interval between the unloading of the two unloading bins 1 must be greater than or equal to the time taken by the unloading vehicle 5 to travel through all the storage bins 4, that is, the unloading vehicle 5 travels from one outermost storage bin 4 to another outermost storage bin. The time required for the unloading vehicle 5 to move to the material bin 4 can ensure that the unloading vehicle 5 will not fail to move to the set position in time, causing the raw materials to miss the storage bin that needs to be discharged into. Therefore, in the case of only the last belt conveyor 3, the time required for the unloading vehicle 5 to move from one outermost storage bin 4 to another outermost storage bin 4 is too long, which will reduce the loading speed of the entire material distribution system. To solve this problem, in this embodiment, a high-level belt conveyor 6 is arranged above the last belt conveyor 3 to form a high-low combination, thereby shortening the moving time of the unloading vehicle 5 on the last belt conveyor 3. The last belt conveyor 3 and the high-level belt conveyor The side of the conveyor 6 is provided with a distributor 7. By default, the distributor 7 adopts the currently common "human" shaped double-channel distributor. A paddle is provided at the main channel opening to control which outlet the raw materials pass through. In this embodiment, the main channel opening for feeding of the distributor is matched with the transfer belt conveyor 10, and the paddle is electrically connected to the main controller, so that the flipping of the paddle is controlled by the main controller, and the raw materials on the transfer belt conveyor 10 are controlled and diverted. The control host will decide whether the distributor 7 diverts the raw materials to the last belt conveyor 3 or the high-position belt conveyor 6 through the storage bin 4 corresponding to the raw materials;

[0028] In the present embodiment, it also includes a material flow detector 8 arranged on the inclined belt conveyor 2 and placed on the side of each lower material bin 1. The material flow detector 8 is electrically connected to the control host to detect whether there is still material in the lower material bin 1 through the material flow detector 8. When the material flow detector 8 detects that no material continues to fall, the discharge door 9 of this lower material bin 1 is controlled to close by the control host. At the same time, the opening and closing detection sensor of the discharge door 9 detects that the discharge door 9 is closed, and the control host starts timing to ensure that the raw materials on the belt conveyor at this time are completely discharged into the storage bin 4. It is preset that after the detection of the closing of the discharge door 9, the control The timing time of the main engine should be equal to the maximum time for the raw materials to be transported on the belt conveyor in the entire material distribution system. It is preset that in this embodiment, a proximity switch is provided on the storage bin 4 (in this embodiment, the proximity switch and material flow detector mentioned are both common sensors in the current field, and those skilled in the art can directly use sensors that can realize such functions). The proximity switch is electrically connected to the control host to meet the requirements of detecting the position of the unloading vehicle 5 through the proximity switch. After the unloading vehicle 5 arrives at the set storage bin 4, the control host will control the unloading door 9 of the lower bin 1 to open for unloading.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
