DETAILED DESCRIPTION

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

Referring to Figures 1-3, a fast alignment coal unloading device of the present invention includes: a belt conveyor 1, which is used to receive coal unloaded by a coal-pulling vehicle and then transport it to a designated area, such as a warehouse; a support frame 11, which is installed at the bottom end of the belt conveyor 1 and is used to support the belt conveyor 1; a receiving hopper 2, which is arranged above the belt conveyor 1, and the bottom end is the receiving end of the belt conveyor 1; a pair of fixed plates 3 are provided and symmetrically installed at both ends of the belt conveyor 1; an isolation assembly 4, which is provided and symmetrically installed at the bottom end of the receiving hopper 2 based on the center line of the receiving hopper 2 ; and can be stretched synchronously during stretching; partition 5; a pair is symmetrically arranged based on the center line of the receiving hopper 2; and is located between the fixed plate 3 and the isolation component 4; and the end is connected to the bottom end of the isolation component 4; the fixing member 51 is installed on the fixed plate 3, and is used to connect the end of the partition 5 away from the isolation component 4 to the fixed plate 3; the support member 6 is symmetrically arranged in a pair based on the receiving hopper 2, and the bottom end is slidably connected to the partition 5; the first hydraulic cylinder 61 is symmetrically arranged in a pair based on the receiving hopper 2, and the shell part is installed on the surface of the fixed plate 3, and the output end is connected to the end of the support member 6 away from the receiving hopper 2;

In actual unloading operations, a feed hopper is usually required to receive the coal unloaded by the transport vehicle; and the transport vehicle is usually a semi-trailer with multiple unloading doors on the side; when unloading, the unloading door is gradually opened, and the driver controls the bucket to overturn during unloading, and the coal in the bucket falls through the unloading door, and the coal is led to the conveyor belt through the feed hopper, and then transported to the designated area through the conveyor belt; during the unloading process, the position of the transport vehicle needs to be controlled so that the different opened unloading doors are aligned with the feed hopper, so the position of the transport vehicle needs to be accurately adjusted, which is difficult and not conducive to operation; to solve the above problems, the embodiment of the present invention provides a receiving hopper 2, and when in use, the driver aligns the unloading door on the side of the vehicle bucket with the receiving hopper 2, and then controls the bucket to overturn, and the coal in the bucket falls downward through the unloading door, and then is received by the aligned receiving hopper 2, and then It falls onto the belt surface of the belt conveyor 1, and the coal is transported to the designated area through the belt conveyor 1; when there is an error in the vehicle's moving distance, resulting in the unloading door on the side of the vehicle bucket being misaligned with the receiving hopper 2, the staff starts the first hydraulic cylinder 61 on the fixed plate 3, and the first hydraulic cylinder 61 drives the receiving hopper 2 to move through the support 6, and stops when the receiving hopper 2 is aligned with the designated unloading door. After that, the receiving hopper 2 can accurately receive the coal that falls off in the unloading door, and there is no need to adjust the vehicle position again, which reduces the adjustment difficulty and is convenient for the staff to operate; specifically, when the position of the receiving hopper 2 is adjusted, the isolation component 4 at the bottom of the receiving hopper 2 can be synchronously lengthened to avoid the isolation component 4 interfering with the adjustment process, and the isolation component 4 can continuously receive the coal that falls from the receiving hopper 2 to the belt conveyor 1, ensuring accurate and stable coal unloading.

As shown in Figures 1-4, the receiving hopper 2 includes: a first combination plate 21, which is a component structure of the receiving hopper 2, and is provided with a pair, and the side is connected to the end of the support member 6; an inclined plate 22, which is installed on the top of the first combination plate 21; a second combination plate 23, which is symmetrically provided with a pair based on the center line of the first combination plate 21, and the end is docked with the first combination plate 21 and the inclined plate 22; a buffer plate 24; a pair is provided and is slidably connected to the side of the second combination plate 23; a third combination plate 25, which is symmetrically provided with a pair based on the center line of the first combination plate 21, and the end is docked with the first combination plate 21 and the inclined plate 22, and the docking position is symmetrical based on the center of the receiving hopper 2; the end of the buffer plate 24 is fixedly connected to the end of the third combination plate 25;

For discharge doors of different sizes, the required sizes of the receiving hopper 2 are also different, so a receiving hopper 2 with adjustable size is designed. Specifically, when adjusting the size of the receiving hopper 2, the output of the first hydraulic cylinder 61 is controlled, and the distance between a pair of first combination plates 21 can be adjusted in conjunction with the support 6. The device stops when the distance between the first combination plates 21 meets the size requirement. In this process, the third combination plate 25 drives the buffer plate 24 to slide and connect with the side of the second combination plate 23, so that the receiving hopper 2 keeps the side closed to ensure normal use. The above improves the applicability of the device to the size of the discharge door.

2-5, the isolation assembly 4 includes: a first rubber strip 41, which is installed on the top of the partition 5; a receiving plate 42, which is installed on the top of the first rubber strip 41 and has a notch on the top; a plug-in plate 43, whose bottom end is plugged into the notch on the top of the receiving plate 42 and whose top end is located above the notch; a second rubber strip 44, whose bottom end is fixedly connected to the top of the plug-in plate 43 and whose top end is fixedly connected to the bottom of the first assembly plate 21;

When the receiving hopper 2 adjusts its position, the plug-in plate 43 slides in the notch on the receiving plate 42, and the first rubber strip 41 and the second rubber strip 44 are deformed synchronously, with a good overall isolation effect. Compared with the isolation component 4 which is entirely made of stretch-deformed materials, it has the advantages of small deformation and not easy to be damaged, and not easy to deform when squeezed by coal; it is stable to use.

As shown in Figures 6-10, a discharge hole 8 is opened on the side of the first combination plate 21, and a fixing frame 81 is inserted through the inside of the discharge hole 8. A conveyor belt 82 is installed on the surface of the fixing frame 81. The side of the fixing frame 81 and located outside the receiving hopper 2 includes: a first fence 83, a pair of which are symmetrically arranged based on the fixing frame 81 and the end is installed on the side of the first combination plate 21; and the side is connected to the fixing frame 81; a second fence 84 is installed at the end of the first fence 83 away from the receiving hopper 2, and the side is slidably connected to the conveyor belt 82; the first fence 83 cooperates with the second fence 84 to intercept the space above the conveyor belt 82; a drive motor 85 is installed on the side of the first fence 83, and is used to drive the conveyor belt 82 to rotate; the first combination plate The side of 21 also includes: a support platform 73, which is installed on the side of the first combination plate 21 and is located above the discharge hole 8; a support spring 72, which is symmetrically installed on the top surface of the support platform 73 based on the support platform 73; a support column 71, the bottom end of which is installed on the top of the support spring 72; a plug-in block 7, which is installed on the top of the support column 71, and a through hole 70 is opened on the side of the inclined plate 22, and the plug-in block 7 is plugged into the inside of the through hole 70; a pressure sensor 74, which is installed on the top of the support platform 73 and is connected to the controller of the drive motor 85 through an electrical signal; an extrusion column 75, the top of which is installed on the bottom end of the plug-in block 7, and the bottom end is in contact with the pressure detection end of the pressure sensor 74; initially, the extrusion column 75 does not squeeze the pressure detection end of the pressure sensor 74;

When the receiving hopper 2 receives coal, there are differences in the speed of coal unloading, and the volume of coal received by the receiving hopper 2 per unit time is limited. Therefore, when the coal unloading speed is too fast, the coal will fill the receiving hopper 2 and overflow. Therefore, a conveyor belt 82 is provided. Before the coal fills the receiving hopper 2, the coal will squeeze the plug-in block 7 inserted in the side through hole 70 of the inclined plate 22. The plug-in block 7 compresses the support spring 72 through the support column 71, and at the same time squeezes the pressure detection end of the pressure sensor 74 through the squeezing column 75. The pressure sensor 74 sends an electric signal to the controller of the drive motor 85. The controller controls the driving motor 85 to rotate, and the driving motor 85 drives the conveyor belt 82 to rotate. The conveyor belt 82 extending into the receiving hopper 2 transports part of the coal in the receiving hopper 2 to the outside of the receiving hopper 2, and then is intercepted and restricted by the first baffle 83 and the second baffle 84. After that, when the coal in the receiving hopper 2 no longer squeezes the plug-in block 7, the conveyor belt 82 is controlled to rotate in the opposite direction to send the coal outside the receiving hopper 2 back into the receiving hopper 2 to complete the unloading. The whole process reduces the risk of overflow due to excessive coal content in the receiving hopper 2, which is beneficial to the coal unloading process.

The second baffle plate 84 is set to be in an inclined state; and the inclined direction is the direction away from the receiving hopper 2; when the second baffle plate 84 is in an inclined state, it is beneficial for the coal to pile up upwards and increase the collected volume of coal.

Initially, part of the coal that enters the receiving hopper 2 will fall onto the surface of the conveyor belt 82; the conveyor belt 82 drives the surface coal to fall to the bottom of the receiving hopper 2; when the pressure detection end of the pressure sensor 74 is pressurized, the conveyor belt 82 is controlled to rotate in the opposite direction; when the coal in the receiving hopper 2 no longer squeezes the plug-in block 7, the conveyor belt 82 restores its initial rotation direction and automatically unloads the collected coal, and there will be no accumulation of coal on the surface of the conveyor belt 82 during subsequent coal leakage.

11-13, the bottom end of the fixing frame 81 includes: a roller 88, which is arranged at the bottom end of the fixing frame 81 and contacts the inner wall of the conveyor belt 82; a connecting frame 87, which is rotatably connected to both ends of the roller 88, and the bottom end of which is located below the conveyor belt 82; a gravity block 89, which is installed at the bottom end of the connecting frame 87; a limiting frame 86, which is provided with a pair and is symmetrical based on the roller 88, and the top end is installed at the bottom end of the fixing frame 81, and the part of the conveyor belt 82 located between the pair of limiting frames 86 is limited;

During the use of the conveyor belt 82, when the coal is transported to the outside of the receiving hopper 2, as the conveyor belt 82 continues to rotate, the coal will squeeze the conveyor belt 82 and generate friction with the conveyor belt 82, causing the conveyor belt 82 to be damaged and loosened faster. Therefore, a roller 88 is provided, and the roller 88 is located between a pair of limiting frames 86. As the conveyor belt 82 rotates, the roller 88 rolls synchronously, and the gravity block 89 continuously stretches the roller 88 downward through the connecting frame 87, causing the roller 88 to continuously generate pressure on the conveyor belt 82, so the conveyor belt 82 is continuously kept in a taut state, thereby increasing its service life.

A support shaft 861 is rotatably provided on the surface of the limiting frame 86 . When the transmission belt 82 passes through the limiting frame 86 , the support shaft 861 supports the transmission belt 82 , thereby reducing the friction between the transmission belt 82 and the limiting frame 86 and reducing the loss of the transmission belt 82 .

2 and 9 , a support plate 9 is provided at the bottom end of the second guardrail 84; the bottom end of the support plate 9 is slidably connected to the surface of the fixed plate 3; the coal transported to the outside of the receiving hopper 2 by the conveyor belt 82 is supported by the fixed frame 81 in cooperation with the first guardrail 83 and the second guardrail 84, and a support plate 9 is provided at the bottom end of the second guardrail 84, so increasing the support points can reduce the burden on the receiving hopper 2, prevent the receiving hopper 2 from deformation and damage, and is beneficial to increasing the service life of the receiving hopper 2.

A support roller 91 is rotatably provided at the bottom end of the support plate 9 to reduce the friction between the support plate 9 and the fixed plate 3 and improve the smoothness of the support.

When in use, the driver aligns the unloading door on the side of the vehicle bucket with the receiving hopper 2, then controls the bucket to overturn, and the coal in the bucket falls downward through the unloading door, is then received by the aligned receiving hopper 2, and then falls onto the belt surface of the belt conveyor 1, and the coal is transported to the designated area through the belt conveyor 1; when there is an error in the vehicle moving distance causing the unloading door on the side of the bucket to be misaligned with the receiving hopper 2, the staff starts the first hydraulic cylinder 61 on the fixed plate 3, and the first hydraulic cylinder 61 drives the receiving hopper 2 to move through the support member 6, and stops when the receiving hopper 2 is aligned with the designated unloading door. After that, the receiving hopper 2 can accurately receive the coal that falls off in the unloading door, and there is no need to adjust the vehicle position again, which reduces the adjustment difficulty and is convenient for the staff to operate; specifically, when the position of the receiving hopper 2 is adjusted, the isolation component 4 at the bottom of the receiving hopper 2 can be synchronously stretched to avoid the isolation component 4 interfering with the adjustment process, and the isolation component 4 can continuously receive the coal that falls from the receiving hopper 2 to the belt conveyor 1, ensuring The coal unloading is accurate and stable; for unloading doors of different sizes, the required sizes of the receiving hopper 2 are also different, so an adjustable size receiving hopper 2 is designed. Specifically, when adjusting the size of the receiving hopper 2, the output of the first hydraulic cylinder 61 is controlled, and the distance between a pair of first combination plates 21 can be adjusted in cooperation with the support member 6. The distance between the first combination plates 21 meets the size requirement and stops. In this process, the third combination plate 25 drives the buffer plate 24 to slide and connect with the side of the second combination plate 23, so that the receiving hopper 2 keeps the side closed to ensure normal use; the above improves the applicable range of the device for the size of the unloading door; when the receiving hopper 2 adjusts its position, the plug-in plate 43 slides in the notch on the receiving plate 42, and the first rubber strip 41 and the second rubber strip 44 are deformed synchronously, and the overall isolation effect is good. Compared with the isolation component 4, which is entirely made of stretch-deformed materials, it has the advantages of small deformation and not easy to be damaged, and not easy to deform when squeezed by coal; it is stable to use.

When the receiving hopper 2 receives coal, there are differences in the speed of coal unloading, and the volume of coal received by the receiving hopper 2 per unit time is limited. Therefore, when the coal unloading speed is too fast, the coal will fill the receiving hopper 2 and overflow. Therefore, a conveyor belt 82 is provided. Before the coal fills the receiving hopper 2, the coal will squeeze the plug-in block 7 plugged into the side through hole 70 of the inclined plate 22. The plug-in block 7 compresses the support spring 72 through the support column 71, and at the same time squeezes the pressure detection end of the pressure sensor 74 through the squeezing column 75. The pressure sensor 74 sends an electrical signal to the controller of the drive motor 85. The controller controls the drive motor 85 to rotate, and the drive motor 85 drives the conveyor belt 82 to rotate. The conveyor belt 82 extending into the receiving hopper 2 transports part of the coal in the receiving hopper 2 to the outside of the receiving hopper 2. Afterwards, the first baffle 83 cooperates with the second baffle 84 to intercept and limit. After that, when the coal in the receiving hopper 2 no longer squeezes the plug-in block 7, the conveyor belt 82 is controlled to rotate in the opposite direction, and the coal outside the receiving hopper 2 is sent back into the receiving hopper 2 to complete the unloading. The whole process reduces the risk of overflow due to excessive coal content in the receiving hopper 2, which is beneficial to the coal unloading process. Among them, when the second baffle 84 is in an inclined state, it is beneficial to the upward accumulation of coal and the increase of the collected coal volume. Among them, when the pressure detection end of the pressure sensor 74 is pressurized, the conveyor belt 82 is controlled to rotate in the opposite direction. When the coal in the receiving hopper 2 no longer squeezes the plug-in block 7, the conveyor belt 82 resumes its initial rotation direction, automatically unloads the collected coal, and there will be no accumulation of coal on the surface of the conveyor belt 82 during the subsequent coal leakage.

During the use of the conveyor belt 82, when the coal is transported to the outside of the receiving hopper 2, as the conveyor belt 82 continues to rotate, the coal will squeeze the conveyor belt 82 and generate friction between the conveyor belt 82, causing the conveyor belt 82 to be damaged and loosened at an accelerated rate. Therefore, a roller 88 is provided, and the roller 88 is located between a pair of limiting frames 86. As the conveyor belt 82 rotates, the roller 88 rolls synchronously, and the gravity block 89 continuously stretches the roller 88 downward through the connecting frame 87, causing the roller 88 to continuously generate pressure on the conveyor belt 82, so the conveyor belt 82 is continuously kept in a taut state, thereby increasing its service life. The surface of the limiting frame 86 is provided with a support shaft 861 for rotation. When the conveyor belt 82 passes through the limiting frame 86, the support shaft 861 supports the conveyor belt 82; the friction between the conveyor belt 82 and the limiting frame 86 is reduced, and the loss of the conveyor belt 82 is reduced; the coal transported to the outside of the receiving hopper 2 by the conveyor belt 82 is supported by the fixed frame 81 in cooperation with the first guardrail 83 and the second guardrail 84, and the bottom end of the second guardrail 84 is provided with a support plate 9, so increasing the support point can reduce the burden on the receiving hopper 2, prevent the receiving hopper 2 from deformation and damage, and is beneficial to increasing the service life of the receiving hopper 2; the bottom end of the support plate 9 is rotatably provided with a support roller 91; the friction between the support plate 9 and the fixed plate 3 is reduced, and the smoothness of the support is improved.

Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods.
