The steps in the method embodiments of this application can be adjusted in order, combined, or deleted according to actual needs.

[0028] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0029] Belt scales are devices used to weigh bulk materials (such as powdered materials and granular materials). They can continuously weigh materials during the material conveying process. They include electronic belt scales, which are classified by load carrier into weighing table load carriers and conveyor load carriers, and by belt speed into single-speed belt scales and variable-speed belt scales.

[0030] After weighing the material on the belt scale, it needs to be transferred to the conveyor belt and transported to the designated location. Existing belt scales are separated from the conveyor belt. The material needs to be transferred from the belt scale to the conveyor belt over a long distance, resulting in poor sealing and easy material spillage and dust generation. Furthermore, there is a lack of protective measures between the belt scale and the conveyor belt, which leads to material spillage during transfer and increases the spread of dust.

[0031] Based on the above problems, an embodiment of the present invention provides a material weighing and conveying integrated device and a conveying system, which can solve the above problems and will be described in detail below.

[0032] Please refer to Figures 1 to 3The material weighing and conveying integrated device includes a supporting bracket 1, a conveyor belt 2, a belt scale 3 and a dust cover 4. The conveyor belt 2 is arranged on the supporting bracket 1. The belt scale 3 is located on the upper part of the conveyor belt 2 and is spaced apart from the conveyor belt 2. The belt scale 3 is installed on the supporting bracket 1. The discharge end of the belt scale 3 corresponds to the conveyor belt 2. The dust cover 4 is arranged on the outside of the belt scale 3.

[0033] In the embodiment of the present invention, the conveyor belt 2 is arranged at the lower part of the belt scale 3, which reduces the distance of material transfer and makes the material transfer more compact, thereby facilitating the arrangement of the dust cover 4. When the material falls into the conveyor belt 2 below after being weighed by the belt scale 3, the dust cover 4 can confine the dust generated by the falling material to the dust cover 4. The material has good sealing performance during transfer, which avoids the large-scale diffusion of dust. Moreover, the dust cover 4 can prevent the material from being spilled during transfer and prevent the material from falling to the ground. At the same time, the conveyor belt 2 is close to the belt scale 3, which is conducive to reducing the generation of dust during the material transfer process.

[0034] It can be understood that the materials in the embodiments of the present invention may include but are not limited to granular materials and dusty materials.

[0035] Specifically, in the embodiment of the present invention, the support bracket 1 is used to provide a mounting location for the conveyor belt 2 and the belt scale 3, and also serves to support the conveyor belt 2, the belt scale 3, and the materials thereon. The support bracket 1 in the embodiment of the present invention has at least four vertical columns, which are respectively arranged in pairs on both sides of the conveyor belt 2 / belt scale 3. Each vertical column is provided with a U-shaped bracket along the direction of operation of the conveyor belt 2, and the open end of the U-shaped bracket is fixed to the side wall of the vertical column.

[0036] The belt scale 3 includes a weighing belt 30, side guards 31, and rollers 32. There are two rollers 32 and two side guards 31, each spaced apart and arranged in parallel to facilitate the placement of the weighing belt 30 on the two rollers 32. The ends of the two rollers 32 are connected to U-shaped brackets on the vertical columns on the corresponding sides. The ends of the rollers 32 are inserted into the U-shaped brackets. To enable the rollers 32 to rotate, the ends of the rollers 32 can be fitted with bearings. The inner ring of the bearing is fixed to the roller 32, and the outer ring of the bearing is fixed to the U-shaped bracket, thereby enabling the rollers 32 to rotate relative to the U-shaped bracket. The end of one of the rollers 32 is connected to a rotary drive member via a coupling. The rotary drive member drives the roller 32 to rotate. The rotary drive member can be a servo motor. The servo motor drives the roller 32 to rotate, and the rotation of the roller 32 drives the weighing belt 30 to rotate, thereby transferring the material on the weighing belt 30 to the conveyor belt 2.

[0037] Of course, the two rollers 32 tighten the weighing belt 30 to prevent the weighing belt 30 from slipping during the rotation. In addition, tightening the weighing belt 30 can also carry more materials and prevent the materials from collapsing the belt surface of the weighing belt 30.

[0038] Optionally, a support plate is provided on the inner side of the weighing belt 30, which abuts against the inner side of the weighing belt 30 to prevent the weighing belt 30 from being damaged by excessive weight of the material. In addition, the weighing belt 30 can also be protected by reducing the amount of material discharged onto the weighing belt 30 per unit time.

[0039] The two rollers 32 are arranged at the same level to ensure that the belt surface of the weighing belt 30 is horizontal, which can prevent the material on the belt surface from sliding and can also prevent the problem of inaccurate weighing caused by the tilt of the belt surface of the weighing belt 30.

[0040] Two side guards 31 are located on the left and right sides of the weighing belt 30. The ends of the rollers 32 pass through the side guards 31 and connect to the U-shaped bracket. The side guards 31 are provided with through holes for the rollers 32 to pass through. Of course, bearings can also be installed in the through holes to enable the rollers 32 and side guards 31 to rotate together. When the side guards 31 and rollers 32 rotate together, the side guards 31 can bear part of the pressure transmitted to the rollers 32 by the weighing belt 30, preventing the full pressure of the material from acting on the rollers 32, which is beneficial to improving the service life of the rollers 32. When the side guards 31 and rollers 32 are arranged without contact, the through holes in the side guards 31 are much larger than the outer diameter of the rollers 32.

[0041] The outer surface of the side guard 31 is fixed to two vertical columns on the same side. The side guard 31 can be connected to the vertical columns by welding, bolting, or other methods. The side guard 31 can also prevent the weighing belt 30 from running off the track. When the weighing belt 30 approaches the side guard 31, the side guard 31 guides the weighing belt 30 back to its original running track. In addition, the top of the side guard 31 is higher than the belt surface of the weighing belt 30, thereby preventing material on the weighing belt 30 from spilling out. Even if material spills from the gap between the weighing belt 30 and the side guard 31, it will fall onto the conveyor belt 2 below, reducing the possibility of material falling to the ground.

[0042] In the embodiment of the present invention, the belt scale 3 is an electronic belt scale, which can directly display the changes in the weighing weight in real time. Since the electronic belt scale is a mature product on the market, other structures and components of the electronic belt scale are not described here.

[0043] The support bracket 1 can be made of a rod or pipe with strong support strength, such as a steel pipe or square beam. The bottom of the support bracket 1 is provided with an adjustable footplate. The adjustable footplate is used to adjust the distance between the bottom of the support bracket 1 and the ground, thereby facilitating leveling of the belt surface of the weighing belt 30. The adjustable footplate can be a commercially available knob-type adjuster, and the height can be adjusted by rotating it. Of course, the support bracket 1 can also have other structural forms, and the adjustable footplate can also use other adjustable devices, and the embodiments of the present invention are not limited to this.

[0044] A dust cover 4 is provided on the top of the electronic belt scale and is connected to the four vertical columns. In the embodiment of the present invention, the dust cover 4 is a box-like structure with a hollow interior, which can confine the dust raised by the material to a certain range. The dust cover 4 of this embodiment can be formed by connecting multiple flat plates, or can also be integrally formed, and the material is not limited. In addition, the specific structural form of the dust cover 4 can also be any of a variety of shapes, such as an arch and a cylinder, without limitation.

[0045] Specifically, the dust cover 4 includes a first cover body 40 and a second cover body 41. The first cover body 40 is connected to four vertical columns. The interior of the first cover body 40 is hollow, which can limit the rising material dust to a certain range. The top of the first cover body 40 is also provided with a feed port 402, through which the material can be discharged onto the weighing belt 30. A material feeder is also provided on the upper part of the first cover body 40, through which the material is fed to the weighing belt 30.

[0046] Optionally, a funnel can be provided at the feed port 402, the upper part of the funnel is connected to the discharge port of the material feeder, and the lower part of the funnel passes through the feed port 402 and is located above the weighing belt 30. The funnel can effectively prevent the material from spilling to the outside of the first cover body 40, and can also slow down the falling material to prevent the material from directly impacting the weighing belt 30, which is beneficial to protecting the weighing belt 30 and reducing the generation of material dust.

[0047] A guide plate 401 is further provided inside the first cover body 40. The upper part of the guide plate 401 is fixed to the inner wall of the first cover body 40, and the lower part of the guide plate 401 is movably connected to the weighing belt 30. A certain distance is left between the belt surface of the weighing belt 30 and the lower end of the guide plate 401. The distance should not be too large or too small. If the distance is too large, it is easy for the material to slide to the side of the weighing belt 30. If the distance is too small, it is easy to cause adverse effects on the operation of the weighing belt 30.

[0048] The guide plate 401 is located on the inner side of the side baffle 31, and the feed port 402 is located between the two guide plates 401. When the material falls from the feed port 402 onto the weighing belt 30, the guide plate 401 can confine the material on the weighing belt 30 to the middle area of ​​the belt surface to prevent the material from sliding to the side of the weighing belt 30. The guide plate 401 can not only prevent the material from falling from the weighing belt 30 to improve the accuracy of weighing, but also suppress the spread of material dust. The dust generated by the material on the weighing belt 30 is confined to a smaller range by the two guide plates 401 and the first cover body 40.

[0049] To further reduce the spread of material dust, a second cover 41 is provided at the end of the first cover 40. The second cover 41 is positioned outside the discharge end of the belt scale 3, and the lower end of the second cover 41 extends to intersect with the conveyor belt 2. This confines the material dust generated during the material transfer process within the first cover 40 and the second cover 41. The second cover 41 can be connected to the first cover 40 by welding, or by any other means, such as bonding, screwing, or riveting.

[0050] The second housing 41 of the embodiment of the present invention also has a box-like structure and can be assembled from multiple flat panels. In other embodiments, the second housing 41 can also have other structural forms, which are not limited to this. Furthermore, the size of the second housing 41 can correspond to the width of the first housing 40, or it can be wider than the first housing 40.

[0051] Optionally, a barrier curtain 411 is provided at the lower portion of the second cover 41. This flexible structure not only absorbs oblique impacts during material transfer but also prevents the spread of dust from the material. The barrier curtain 411 can be constructed by splicing together multiple rubber strips or multiple plastic strips. The lower end of the barrier curtain 411 is movably engaged with the surface of the conveyor belt 2, effectively preventing the spread of dust from the material. Alternatively, the lower end of the barrier curtain 411 can be spaced apart from the surface of the conveyor belt 2.

[0052] The specific form and material of the barrier curtain 411 are not limited in the embodiments of the present invention. The barrier curtain 411 can be an integral structure, such as a whole piece of barrier cloth, or a distributed structure, such as a plurality of rubber barrier strips. The material can be rubber, plastic, or a flexible structure made of other materials.

[0053] A door 412 is also provided on the side of the second housing 41. The door 412 is rotatably connected to the second housing 41 via a hinge. When the door 412 is opened, the material falling onto the belt scale 3 can be observed to prevent material blockage and spillage. A handle is provided on the door 412, which allows for convenient opening and closing of the door 412.

[0054] Optionally, the top side of the box door 412 is rotatably connected to the second cover body 41 through a hinge or a hinge. When there is no need to check the situation inside the dust cover 4, the box door 412 will automatically close due to its own weight, and there is no need to set an additional lock. When checking again, it can be directly flipped up, which is very convenient.

[0055] refer to Figure 3 Combined with Figure 1 A convergence baffle 5 is also provided at the lower part of the belt scale 3. The lower end of the convergence baffle 5 is connected to the conveyor belt 2. The convergence baffle 5 redirects the materials scattered on both sides of the conveyor belt 2 to the middle part of the conveyor belt 2 to prevent the materials from spilling from both sides of the conveyor belt 2 to the ground.

[0056] In an embodiment of the invention, the convergence baffle 5 includes a vertical connection part 50, an inclined guide part 51 and a flexible part 52, the upper end of the inclined guide part 51 is connected to the vertical connection part 50, the lower end of the inclined guide part 51 is connected to the flexible part 52, and the flexible part 52 is connected to the conveyor belt 2.

[0057] Specifically, the vertical connection portion 50 and the inclined guide portion 51 are both flat plates. The vertical connection portion 50 is vertically arranged, and the inclined guide portion 51 is inclined relative to the vertical direction. The upper portion of the inclined guide portion 51 is connected to the vertical connection portion 50, and the lower portion of the inclined guide portion 51 is connected to the flexible portion 52. The lower end of the inclined guide portion 51 faces one side of the middle of the conveyor belt 2, and the flexible portion 52 is movably connected to the conveyor belt 2, thereby guiding the material to the middle of the conveyor belt 2. The top of the vertical connection portion 50 is connected to the vertical column of the support bracket 1. In this way, material falling from the side of the weighing belt 30 can also be guided back to the conveyor belt 2, preventing the material from directly spilling onto the ground. This also helps prevent material dust from spreading outward from the side below the belt scale 3.

[0058] The flexible portion 52 may be made of a rubber sheet, which will not cause significant damage when in contact with the conveyor belt 2. Of course, the flexible portion 52 may also be made of other materials or other structural forms, and the embodiments of the present invention are not intended to limit this.

[0059] The conveyor belt 2 is arranged at the lower part of the belt scale 3, and the conveyor belt 2 can be connected to the vertical column of the support bracket 1. Of course, the conveyor belt 2 also has side baffles, which can be connected to the vertical columns.

[0060] The embodiment of the present invention provides an integrated material weighing and conveying device, which integrates a belt scale 3 with a conveyor belt 2, thereby reducing the distance of material transfer. At the same time, a dust cover 4 is provided. When the material falls onto the conveyor belt 2 below after being weighed by the belt scale 3, the dust cover 4 can confine the dust generated by the falling material to the dust cover 4, thereby preventing the dust from spreading over a large area. In addition, the dust cover 4 can prevent the material from being spilled during transfer, preventing the material from falling to the ground. At the same time, the proximity of the conveyor belt 2 to the belt scale 3 is conducive to reducing the generation of dust during the material transfer process. In short, the device of the embodiment of the present invention is not only compact in structure, but also helps to reduce the generation and spread of material dust, while reducing the chance of material spilling to the ground.

[0061] An embodiment of the present invention further provides a conveying system, including the above-mentioned integrated material weighing and conveying device, which has all the functions of the integrated material weighing and conveying device.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
