Description

Technical Field

[0001] This utility model relates to the field of material production and manufacturing, and in particular to a material conveying system. Background Technology

[0002] In the production of granular materials, material sorting is typically required based on demand. Precise classification and quality control of materials improve the final product's qualification rate and production efficiency. The typical sorting process involves a conveyor belt transporting material to a hopper, discharging a certain amount of material into the hopper, and then unloading the material into a container, thus sorting the granular materials. However, existing material sorting methods have some shortcomings: during the transport of material to and from the hopper, the pipelines of the transport system must withstand the direct impact of unloading, leading to a reduced lifespan of the system and increased maintenance pressure. Furthermore, during material transport, sufficient initial velocity is required for smooth transport; however, excessive initial velocity can cause impact splashing, resulting in material loss. Meanwhile, the existing material transportation system adopts a multi-pipeline connection mode, which can easily cause blockages and stagnation when materials are transported and transferred in the pipelines, affecting the safety and efficiency of material transmission. The overall controllability of material transmission is poor. Especially in some cases where fine sorting is required, the instability of material transmission can also have a significant impact on the efficiency and accuracy of the sorting process. Utility Model Content

[0003] The present invention aims to overcome at least one of the defects of the prior art and provide a material transfer system.

[0004] This utility model provides a material conveying system, including: a conveying component, and a material dropping device disposed above the starting side of the conveying component; a material guiding device is also provided between the conveying component and the material dropping device, and a material blocking plate is provided on the discharge side of the material guiding device, the material blocking plate being movably connected to the material guiding device.

[0005] In this technical solution, by setting the material guiding device close to the starting end of the transmission component, the material is ensured to enter the transmission channel smoothly. The movable connection between the material blocking plate and the material guiding device balances the impact of the material during transportation: when the material flow rate is low, the material blocking plate relies on its own weight or elastic element to maintain a small opening, prolonging the contact time between the material and the guiding surface to accumulate the material appropriately and using the gravitational potential energy of the material to regulate the falling speed. At the same time, it improves the scattering problem of the material during the free fall stage, and enhances the uniformity and stability of the material transmission.

[0006] Furthermore, the material guiding device is provided with an inclined material dropping channel, the inlet of the material dropping channel is located directly below the material dropping port of the material dropping device and there is a gap between them; the material blocking plate is provided on the outlet of the material dropping channel.

[0007] In this technical solution, an inclined material drop channel is set on the material guiding device to receive the material falling from the drop port. The gap between the material drop channel and the drop port allows the airflow between the channels to dissipate and avoids backpressure. At the same time, the material gains a certain initial speed and direction by falling under gravity. This reduces the material transmission distance and achieves precise guidance of the drop position, thereby improving the efficiency and stability of the material transmission along the material drop channel.

[0008] Preferably, the material discharge channel is a straight channel, and the angle between the material discharge channel and the horizontal plane is 40° to 80°. This ensures that the material can be transported smoothly and in a straight line along the material discharge channel, avoiding material scattering and loss. At the same time, it can make full use of the gravitational potential energy of the falling material to obtain the most suitable transportation speed, thereby achieving efficient transportation.

[0009] Furthermore, the cross-section of the material discharge channel gradually decreases from top to bottom, causing the material to continuously converge and gather during the accelerated transportation process on the material discharge channel, further enabling the material to be transported in a directional manner and avoiding material spillage and loss during transportation.

[0010] Furthermore, the material guiding device includes a groove-shaped main body, on which the material guiding channel is disposed. The main body is open to the side facing the transmission component, thus exposing the material guiding channel. By setting a groove-shaped main body in the material guiding device, while retaining three guiding surfaces, it is fully open to the transmission component side, avoiding airflow obstruction caused by the closed material drop channel, and ensuring the efficiency of directional material transport. At the same time, the open slot creates an unobstructed observation window for the material transport process, facilitating real-time monitoring of the material drop status and sorting accuracy, improving process controllability. Additionally, it can also be used as an internal maintenance channel for the equipment, reducing the overall maintenance difficulty of the material transport system.

[0011] Furthermore, the bottom of the main body is an arc-shaped bottom surface that is concave from both sides to the middle. By setting the bottom of the main body to adopt a continuous arc-shaped configuration with high sides and concave center, when the material falls rapidly down to the arc-shaped bottom surface through the inclined channel, it will automatically gather along the center line of the groove with the lowest curvature due to the centripetal constraint. This not only ensures the material transportation efficiency but also corrects the material transportation trajectory, further avoiding material spillage and loss.

[0012] Furthermore, the feed inlet of the main body is horizontally set, and the discharge outlet of the main body is inclined. In the main body of the guiding device, the horizontally set feed inlet fully expands to receive the material falling from the dropping device. At the same time, the vertically set discharge outlet allows the material to fall vertically after its kinetic energy is redirected by the guiding device. This provides a precise interception reference surface for the material to hit the blocking plate, thereby ensuring good coordination between the various devices in the material transportation system, realizing the directional transportation of materials, and ensuring the transportation efficiency of materials.

[0013] Preferably, the material blocking sheet is rotatably connected to the material guiding device, and the blocking surface formed gradually increases from the side closer to the rotation center to the side farther away from the rotation center.

[0014] In this technical solution, the material blocking plate adopts a structure that is narrower near the rotating shaft end and wider far from the rotating shaft end. When the material blocking plate is closed, its outline completely covers the arc-shaped edge of the material guide device's outlet, ensuring that the falling material can effectively impact the material blocking plate. During the opening process of the material blocking plate, the small cross-section area near the rotating shaft rotates first, allowing the material accumulated on the material blocking plate to fall flexibly from the small cross-section area. Furthermore, as the rotation angle increases, the larger cross-section area gradually releases more flow area for the falling material, ensuring that the material blocking plate reacts promptly and avoiding the risk of material jamming.

[0015] Furthermore, the back side of the main body is provided with a support column, which includes: a first support column located below the material discharge port, and a second support column spaced apart from the first support column.

[0016] In this technical solution, the first support column is set in the vertical projection area of ​​the material drop port to directly support and reinforce the position where the main body directly receives the impact of falling materials, thus preventing structural deformation. At the same time, the second support columns are set at intervals and are arranged in low-stress areas. Together with the first support column, they form a composite support system that resists bending and torsion, thereby dispersing the stress distribution of the main body, ensuring the overall structural rigidity and impact resistance of the material conveying system, and improving the service life of the system.

[0017] Furthermore, a receiving platform is provided below the material feeding device, and a connecting plate is provided on the discharge side of the main body; a drive motor is provided on the connecting plate, and the connecting plate is rotatably connected to the material guiding device through the drive motor.

[0018] In this technical solution, the receiving platform is set at the bottom of the material dropping device and connected to the body of the material guiding device as a load-bearing structure, which further provides structural support for the material guiding device and reduces the impact risk to the material guiding device when the material falls directly into the material guiding device. At the same time, a mounting cavity is provided on one side of the receiving platform, which can accommodate the drive motor. This allows the drive motor to be hidden inside the mounting cavity of the receiving platform, reducing the entry of external dust and extending the life of the drive motor. At the same time, the heat dissipation efficiency is optimized by utilizing the thermal conductivity of the metal of the receiving platform body.

[0019] The beneficial effects of this utility model are as follows: 1. A material conveying system is provided. By setting the material guiding device close to the starting end of the conveying component, the material is ensured to enter the conveying channel smoothly. The movable connection between the material blocking plate and the material guiding device balances the impact of the material during transportation. When the material flow rate is low, the material blocking plate maintains a small opening by relying on its own weight or elastic elements, prolonging the contact time between the material and the guiding surface to accumulate the material appropriately and using the gravitational potential energy of the material to regulate the falling speed. At the same time, it improves the scattering problem of the material during the free fall stage and enhances the uniformity and stability of the material conveying.

[0020] 2. In the main body of the material guiding device, the horizontally set inlet fully expands to receive the material falling from the dropping device. At the same time, the vertically set outlet allows the material to fall vertically after its kinetic energy is redirected by the material guiding device. This provides a precise interception reference surface for the material to hit the blocking plate, thereby ensuring good coordination between the various devices in the material transportation system, realizing the directional transportation of materials, and ensuring the efficiency of material transportation.

Detailed Implementation The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Example 1 like Figure 1 As shown, this embodiment provides a material conveying system, including a conveying component 100 and a dropping device 200 disposed above the starting side of the conveying component 100; a guiding device 300 is also provided between the conveying component 100 and the dropping device 200, and a blocking plate 310 is provided on the discharge side of the guiding device 300, the blocking plate 310 being movably connected to the guiding device 300. Specifically, by setting the guiding device 300 close to the starting end of the conveying component 100, the material is ensured to smoothly enter the conveying channel. The movable connection between the blocking plate 310 and the guiding device 300 balances the impact of the material during transportation: when the material flow rate is low, the blocking plate 310 relies on its own weight or elastic elements to maintain a small opening, prolonging the contact time between the material and the guiding surface to appropriately accumulate the material and utilize the gravitational potential energy of the material to regulate the dropping speed, while improving the scattering problem of the material during free fall, thus improving the uniformity and stability of material conveying.

[0026] Furthermore, the material guiding device 300 is provided with an inclined material dropping channel 320. The inlet 321 of the material dropping channel 320 is located directly below the discharge port 201 of the material dropping device 200 and a gap is left between them. The material blocking plate 310 is provided on the outlet 322 of the material dropping channel 320. Specifically, by providing an inclined material dropping channel 320 on the material guiding device 300 to receive the material falling from the discharge port 201, and by leaving a gap between the material dropping channel 320 and the discharge port 201, airflow between the channels can be allowed to dissipate, avoiding backpressure, and the material can gain a certain initial speed and direction by falling under gravity. This reduces the material transmission distance while achieving precise guidance of the dropping position, thereby improving the efficiency and stability of material transmission along the material dropping channel 320.

[0027] like Figure 3 As shown, preferably, the material discharge channel 320 is a straight channel, and the angle between the material discharge channel 320 and the horizontal plane is... Figure 3 The center is marked α, which ranges from 40° to 80°. This ensures that the material can be transported smoothly and in a straight line along the material drop channel 320, avoiding material scattering and loss. At the same time, it can make full use of the gravitational potential energy of the falling material to obtain the most suitable transportation speed, thereby achieving efficient transportation.

[0028] Furthermore, the cross-section of the material drop channel 320 gradually decreases from top to bottom, causing the material to continuously converge and gather during the accelerated transportation process on the material drop channel 320, further directing the material transportation and avoiding material spillage and loss during transportation.

[0029] Furthermore, the material guiding device 300 includes a groove-shaped main body 330, and a material guiding channel 331 is disposed on the main body 330. The main body 330 is open on the side facing the transmission component 100, so that the material guiding channel 331 is exposed. By setting a groove-shaped main body 330 in the material guiding device 300, while retaining three flow guiding surfaces, it is fully open on the side facing the transmission component 100, avoiding airflow obstruction caused by the closed material transport channel 320, and ensuring the directional transport efficiency of the material. At the same time, the open slot creates an unobstructed observation window for the material transport process, which is convenient for real-time monitoring of the material dropping status and sorting accuracy, improving process controllability. In addition, it can also be used as an internal maintenance channel for the equipment, reducing the overall maintenance difficulty of the material transport system.

[0030] like Figure 2 As shown, the bottom of the main body 330 is an arc-shaped bottom surface that is concave from both sides to the middle. By setting the bottom of the main body 330 to adopt a continuous arc surface configuration with high sides and concave center, when the material falls rapidly down to the arc-shaped bottom surface through the inclined channel, it will automatically gather along the center line of the groove with the lowest curvature due to the centripetal constraint. This not only ensures the material transportation efficiency but also corrects the material transportation trajectory, further avoiding material spillage and loss.

[0031] Furthermore, the feed inlet 321 of the main body 330 is horizontally set, and the discharge outlet 322 of the main body 330 is inclined. In the main body 330 of the guiding device 300, the horizontally set feed inlet 321 fully expands to receive the material falling through the dropping device 200. At the same time, the vertically set discharge outlet 322 allows the material to fall vertically after its kinetic energy is redirected by the guiding device 300. This provides a precise interception reference surface for the material to hit the blocking plate 310, thereby ensuring good coordination between the various devices in the material transportation system, realizing the directional transportation of materials, and ensuring the transportation efficiency of materials.

[0032] Preferably, the material blocking plate 310 is rotatably connected to the material guiding device 300, and the blocking surface it forms gradually increases from the side closer to the rotation center to the side farther away from the rotation center. Specifically, the material blocking plate 310 adopts a structure that is narrower near the rotating shaft end and wider far from the rotating shaft end, so that when the material blocking plate 310 is closed, its outline completely covers the arc-shaped edge of the material guiding device 300 outlet 322, ensuring that the falling material can effectively impact the material blocking plate 310; during the opening process of the material blocking plate 310, the small cross-sectional area near the rotating shaft rotates first, allowing the material accumulated on the material blocking plate 310 to fall flexibly from the small cross-sectional area, and further, the large cross-sectional area gradually releases more flow area for the falling material as the rotation angle increases, which not only ensures the timely response of the material blocking plate 310, but also avoids the risk of material jamming.

[0033] Furthermore, a support column 340 is provided on the back side of the main body 330. The support column 340 includes a first support column 341 located below the material discharge port 201 and a second support column 342 spaced apart from the first support column. Specifically, the first support column 341 is located in the vertical projection area of ​​the material discharge port 201 to directly support and reinforce the position of the main body 330 that directly receives the impact of falling materials, thus preventing structural deformation. At the same time, the second support column 342 is spaced apart and arranged in low-stress areas, forming a composite support system with the first support column 341 to resist bending and torsion. This disperses the stress distribution of the main body 330 as a whole, ensuring the overall structural rigidity and impact resistance of the material conveying system and improving the service life of the system.

[0034] Furthermore, a receiving platform 350 is provided below the material feeding device 200, and a connecting piece 332 is provided on the discharge side of the main body 330; a drive motor 360 is provided on the connecting piece 332, and the connecting piece is rotatably connected to the guiding device 300 through the drive motor 360. Specifically, the receiving platform 350 is set at the bottom of the material feeding device 200 as a load-bearing structure and is connected to the main body of the guiding device 300, further providing structural support for the guiding device 300 and reducing the impact risk to the guiding device 300 when the material falls directly into the guiding device 300; at the same time, fixing the drive motor 360 together with the main body 330 through the connecting piece 332 helps to accurately position the material blocking piece 310. Furthermore, the empty space on one side of the receiving platform 350 forms an installation cavity to accommodate the drive motor 360, which allows the drive motor 360 to be hidden in the installation cavity of the receiving platform 350, reducing the entry of external dust and extending the life of the drive motor 360.
