Some of these materials are characterized by high temperature and large volume. Existing conveying and metering devices are prone to damage and have short service lives under the long-term impact of high-temperature materials and continuous high loads from large flow rates. Summary of the Invention

[0003] The main purpose of this invention is to propose a transportation metering device to solve the problem that existing transportation metering devices are easily damaged under high load conditions.

[0004] To achieve the above objectives, the present invention proposes a transport metering device, which includes a frame, a support beam detachably disposed within the frame;

[0005] A transport mechanism, mounted on the frame, includes a drive assembly, at least two chains, and multiple chain plate assemblies. The two chains are arranged side-by-side along a first direction and are respectively driven and connected to the drive assembly. The multiple chain plate assemblies are supported on the two chains and arranged sequentially along a second direction to form a transport channel for material transport. The first direction and the second direction intersect. Each chain plate assembly is provided with a wheel on both sides along the first direction. The chain plate assembly has a bearing surface for bearing materials, and a guide portion is provided on the bearing surface.

[0006] The measuring mechanism includes a measuring component and a weighing guide rail. The measuring component includes the measuring display device and a weighing sensor. The weighing sensor is disposed on the weighing guide rail and electrically connected to the measuring body. The weighing guide rail is disposed on the support beam and located below the chain plate assembly. The trolley is rotatably disposed on the weighing guide rail.

[0007] In one embodiment, the chain plate assembly includes a plate body having the bearing surface and opposing first and second ends, the direction of the first end toward the second end being the conveying direction of the conveying channel, the guide portion including a first protrusion located at the second end, the first protrusion having a clearance space below the first protrusion, and the first end of one of two adjacent plate bodies being disposed within the clearance space of the other plate body.

[0008] In one embodiment, the guide portion further includes a second protrusion located at the first end, the height of the second protrusion being less than the height of the first protrusion.

[0009] In one embodiment, the upper surface of the first protrusion and / or the second protrusion is a smoothly transitioned arc-shaped surface, and the highest point of the first protrusion is higher than the end height of the second protrusion for overlapping and mating.

[0010] In one embodiment, the metering component further includes a speed sensor electrically connected to the metering display device, and two weighing guide rails are provided, which are respectively fixed at both ends of the frame, and each guide rail is provided with at least two weighing sensors.

[0011] In one embodiment, the system further includes a first enclosure and a second enclosure, which are disposed at both ends of the frame along a second direction. The first enclosure has a feed inlet, and the second enclosure has a discharge outlet.

[0030] Currently widely used belt scales are prone to problems such as aging, burning, misalignment, or wear when their conveyor belts are in prolonged contact with high-temperature, sharp, or high-volume materials, leading to inaccurate measurement and frequent maintenance. Some materials that need to be transported often have characteristics of high temperature and large volume. Under the long-term impact of high-temperature materials and continuous high loads from large flow rates, existing conveying and metering devices are easily damaged and have a short service life. Therefore, this utility model proposes a transport metering device.

[0031] Please refer to Figures 1 and 2. In one embodiment of this utility model, a device for transporting and metering materials is provided. The transport and metering device includes a frame 100, which includes a frame 110 and a support beam 120 detachably disposed within the frame 110; it also includes a transport mechanism, which includes a drive assembly 300, at least two chains 210, and multiple chain plate assemblies 220. The two chains 210 are arranged side-by-side along a first direction 130 and are respectively driven and connected to the drive assembly 300. The multiple chain plate assemblies 220 are supported on the two chains 210 and arranged sequentially along a second direction 140 to form a transport channel for transporting materials. The first direction 130 and the second direction 140 intersect. The chain plate assembly 220 is provided with drag wheels 230 on both sides along the first direction 130. The chain plate assembly 220 has a bearing surface for carrying materials, and a guide portion is provided on the bearing surface. It also includes a metering mechanism 500, which includes a metering component and a weighing guide rail 510. The metering component includes the metering display device and a weighing sensor 520. The weighing sensor 520 is disposed on the weighing guide rail 510 and electrically connected to the metering body. The weighing guide rail 510 is disposed on the support beam 120 and located below the chain plate assembly 220. The drag wheels 230 are rotatably disposed on the weighing guide rail 510.

[0032] It is understood that each of the chain plates is provided with a drag wheel 230 at both sides of the first direction 130, and the drag wheel 230 can rotate freely relative to the chain plate; each of the chain plates is provided with a protrusion, which is part of the chain plate structure and is used for the chain plate assembly 220 to deflect when transporting large materials.

[0033] The metering mechanism 500 is used to weigh the material being conveyed in real time, and includes a metering component, a weighing sensor 520, and a weighing guide rail 510. The weighing guide rail 510 is fixedly installed on the support beam 120 of the frame 100, and is installed below the chain plate assembly 220; the weighing sensor 520 is installed on the weighing guide rail 510 to sense pressure signals; the weighing sensor 520 is electrically connected to the metering component and transmits the detected weight signal to the display for processing and display; the drag wheels 230 on both sides of the chain plate assembly 220 are directly and rotatably mounted on the upper surface of the weighing guide rail 510; the gravity of the material is transmitted to the weighing guide rail 510 via the chain plate and drag wheels 230, and is then detected by the weighing sensor 520 below it.

[0034] Optionally, multiple chain plate assemblies 220 may be made of metal to prevent damage to the transport mechanism from high-temperature materials during transport.

[0035] During operation, the drive component 300 operates, driving the two chains 210 to move synchronously in a circular motion. The chain plate assembly 220, fixed on the chains 210, moves accordingly, forming a continuous conveying channel. Material falls onto the chain plate from the feed end and is conveyed forward. The gravity of the material is smoothly transmitted through the chain plate and the rollers 230 to the weighing guide rail 510 and the weighing sensor 520 below. The weighing sensor 520 sends the real-time weight signal to the metering component, which can calculate the cumulative weight of the material and complete dynamic metering.

[0036] The transport metering device in this embodiment is equipped with a transport mechanism consisting of a drive assembly 300, a chain 210, and multiple chain plate assemblies 220. Each chain plate assembly 220 is provided with a protrusion, which helps to prevent excessively heavy materials from deflecting during the transport process.

[0037] The device also includes a weighing mechanism 500, which has a weighing guide rail 510 mounted on the support beam 120. The drag wheels 230 on both sides of the chain plate assembly 220 are rotatably mounted on the weighing guide rail 510. Through the rolling cooperation between the drag wheels 230 and the guide rail, the gravity transmitted from the chain plate assembly 220 can be transmitted to the weighing sensor 520 below more smoothly and evenly, effectively reducing friction, vibration and off-center load impact during operation, thereby significantly improving the accuracy of dynamic weighing.

[0038] The device also has a frame 110 and a frame 100 with support beams 120 detachably disposed in the installation space. This arrangement allows the load-bearing support beams 120 to be detachably replaced. In the event of local deformation or damage, there is no need to perform large-scale cutting and welding on the overall frame 110, which greatly reduces maintenance difficulty, shortens downtime, and helps to maintain the assembly accuracy and stability of the equipment in the long term.

[0039] Furthermore, the drive assembly 300 mainly includes: a drive motor 301, a drive shaft, a drive sprocket 303, and a coupling. The drive sprocket 303 on the drive shaft meshes with two chains 210 respectively. The drive shaft is horizontally positioned at one end of the frame 100 via a bearing housing; the drive sprockets 303 are fixedly mounted on the drive shaft, and their number corresponds to the number of chains 210; the coupling is used to directly connect the output shaft of the drive motor 301 to the drive shaft; the drive motor 301 is fixedly mounted at the end of the frame 110 of the frame 100, and its output shaft is coaxially directly connected to the drive shaft through the coupling. Optionally, the drive motor 301 is a geared motor with a built-in reduction mechanism.

[0040] Referring to Figure 3, in one embodiment, the chain plate assembly 220 includes a plate body 221, the plate body 221 having the bearing surface and opposing first end and second end, the direction of the first end toward the second end being the conveying direction of the conveying channel, the guide portion including a first protrusion 223 located at the second end, the first protrusion 223 having a clearance space 2231 below the first protrusion 223, and the first end of one of the two adjacent plate bodies 221 being disposed within the clearance space 2231 of the other plate body 221.

[0041] During assembly, multiple plates 221 are connected by a chain 210 and arranged sequentially along the conveying direction. Adjacent plates 221 are connected in an interlocking manner; for example, the second end of the front plate 221 engages with the first end of the rear plate 221, with the first end of the rear plate 221 positioned and accommodated within the clearance space 2231 of the second end of the front plate 221. This creates an overlapping or nested relationship between adjacent plates 221 at the connection point, which helps reduce or eliminate vertical movement or gaps caused by hinges between plates 221, making the entire conveying surface smoother and more continuous. The nested end structures can also reduce leakage of fine particles from the joints of plates 221 to some extent. By placing the first end of one of two adjacent plates 221 within the clearance space 2231 of the other plate 221, the mutual constraint of adjacent plates 221 in the non-hinge direction can be effectively enhanced, improving the integrity and stability of the chain plate assembly 220 under complex stress.

[0042] Furthermore, fixed seats 224 are provided at both ends of the plate 221, and the drag wheel 230 is rotatably connected to the fixed seats 224 via a rotating shaft. The plate 221 is also provided with connecting holes 225 for connecting and fixing the chain 210. Through the fixed connection between the connecting holes 225 on the plate 221 and the chain 210, it can be ensured that the traction force generated by the drive assembly 300 can drive the entire chain plate train efficiently and without slippage.

[0043] Referring to Figures 3 and 4, in one embodiment, the guide portion further includes a second protrusion 222 located at the first end, and the height of the second protrusion 222 is less than the height of the first protrusion 223.

[0044] By setting the height of the second protrusion 222 to be less than the height of the first protrusion 223, the plate 221 forms an asymmetrical profile in the second direction 140, that is, the protrusion at the second end is higher than the first end, so that when conveying materials, the materials tend to move from the lower feed end to the higher discharge end. During the conveying process, the materials are guided by inertia, vibration and the shape of the plate surface, and will naturally move towards the middle and front of the plate 221, which helps to prevent the materials from accumulating at the edge of the plate 221 or spilling from the side; at the same time, it also allows the front end of the rear plate 221 to naturally extend to the area below the rear protrusion of the front plate 221.

[0045] Referring to Figure 6, in one embodiment, the upper surfaces of the first protrusion 223 and / or the second protrusion 222 are smoothly transitioned arc-shaped surfaces. The highest point of the first protrusion 223 is higher than the end height of the second protrusion 222, for overlapping fit. The smooth arc-shaped surface completely eliminates sharp edges, allowing materials to slide smoothly within the plate 221 itself and when transitioning from one plate 221 to the next, greatly reducing jamming, obstruction, and adhesion. This overlapping fit not only reduces deflection and deformation at the connection points of the plate 221 but also makes the entire chain plate assembly 220 a continuous whole, thereby improving the stability of the conveyor.

[0046] In one embodiment, the metering component further includes a speed sensor electrically connected to the metering display device. Two weighing guide rails 510 are provided and fixed at both ends of the frame 100 respectively. Each guide rail is provided with at least two weighing sensors 520.

[0047] Optionally, the speed sensor is installed at the driven end of the transport mechanism or directly coupled to the chain 210 and sprocket, for real-time detection of the actual linear speed of the chain 210. The signal output terminal of the speed sensor is electrically connected to the metering and display device, thereby synchronously transmitting the speed signal to the metering and display device.

[0048] The metering display device simultaneously receives weight signals from the weighing sensor 520 and speed signals from the speed sensor. Through its built-in processor, the device can calculate and display the instantaneous flow rate and cumulative weight of the material in real time, achieving continuous dynamic metering.

[0049] Understandably, the two weighing guide rails 510 are distributed along the first direction 130 of the frame 100 and are securely installed on the support beam 120 of the frame 100 by bolts, welding or other fixing methods. That is, one weighing guide rail 510 is fixed at one end of the frame 100 along the width direction, and the other is fixed at the opposite end, so that the two guide rails together span across the underside of the conveying channel.

[0050] Below each of the weighing guide rails 510, at least two load cells 520 are disposed. The load cells 520 are installed at intervals on the support beam 120, and their sensing ends are in contact with the bottom surface of the weighing guide rail 510 or connected through mounting parts, so as to accurately sense the pressure borne by the guide rail.

[0051] Optionally, the signal outputs of all load cells 520 are connected to a common leveling junction box or directly to the metering assembly.

[0052] The leveling junction box is used to connect the output signal lines of all sensors, algebraically sum their signals, and combine them into a single total weight signal. By adjusting the corresponding potentiometers within the box, the sensitivity differences and initial output imbalances of the individual sensors caused by the aforementioned reasons can be compensated manually or automatically. This ensures that when the weight is evenly applied across the entire weighing platform, the contribution ratio of the four sensors to the total signal is the same, thereby eliminating weighing errors caused by off-center loading.

[0053] Referring to Figures 1 and 5, in one embodiment, the conveying and metering device further includes a first enclosure 150 and a second enclosure 160. The first enclosure 150 and the second enclosure 160 are disposed at both ends of the frame 110 along a second direction 140. The first enclosure 150 is provided with a feed inlet, and the second enclosure 160 is provided with a discharge outlet. The driving assembly 300 is disposed on the frame 110 near the feed inlet, and a tensioning assembly 400 is disposed on the frame 110 near the discharge outlet to disperse the stress of the conveying mechanism.

[0054] It is understood that the drive assembly 300 is integrally disposed on the frame 110 near the feed inlet; the tensioning assembly 400 is disposed on the frame 110 near the discharge outlet. The tensioning assembly 400 is connected to the chain 210 via a driven shaft 430, and is used to automatically adjust and maintain appropriate tension in the chain 210 to compensate for slack caused by wear, stretching, or temperature changes, ensuring stable meshing between the chain 210 and the sprocket, while absorbing impact stress that may occur during operation and protecting the drive assembly 300. It is understood that the drive shaft is the driving shaft 302, and the shaft on the opposite side of the drive assembly 300 is the driven shaft 430.

[0055] Furthermore, one specific implementation of the tensioning assembly 400 includes a tensioning seat 410 and an elastic adjustment assembly 420. The tensioning seat 410 is slidably mounted on the frame 100 and installed on the frame via a sliding block and guide rail or similar cooperating structure; the elastic adjustment assembly 420 is used to drive the tensioning seat 410 to move.

[0056] Furthermore, the elastic adjustment assembly 420 includes: a lead screw 421 connected at one end to the tensioning seat 410, a spring 422 sleeved on the lead screw 421, and a nut 423 screwed onto the lead screw 421 and located outside the spring 422.

[0057] By rotating the nut 423, the compression of the spring 422 on the lead screw 421 can be changed. The elastic force generated by the compressed spring 422 acts continuously on the tensioner 410 through the lead screw 421, providing an adjustable push or pull force to the tensioner 410, thereby transmitting the required tension to the chain 210. When the chain 210 is slack, the elastic force of the spring 422 pushes the tensioner 410 to move, automatically tightening the chain 210; when the chain 210 is too tight or subjected to impact, the spring 422 can undergo elastic deformation to buffer the stress.

[0058] The tensioning mechanism has a certain degree of self-adaptability, which can automatically compensate for the slight elongation of the chain 210 and play a buffering role when the load changes suddenly, protecting the entire transmission system and extending the service life of the equipment.

[0059] In one embodiment, the frame 110 is an I-beam and the support beam 120 is a sheet metal bending piece.

[0060] Optionally, the frame 110 is made of standard I-beams. Due to their large moment of inertia and strong bending resistance, I-beams can provide the entire device with extremely high longitudinal rigidity and load-bearing capacity, effectively resisting the continuous loads and possible impact loads generated when conveying large flow rates and high specific gravity materials, ensuring the long-term stability and non-deformation of the device's foundation structure.

[0061] Furthermore, other structural components constituting the frame 110, including columns, beams, and legs, are all sheet metal bent parts manufactured using sheet metal bending technology. The columns, beams, and legs are integrally formed by cutting and bending steel plates. The sheet metal bent parts are assembled with the I-beam main beam, and with each other, using detachable connectors such as bolts and pins. This makes the entire frame 100 a highly modular structure, eliminating the need for complex welding during on-site installation; assembly and fastening according to drawings are sufficient, greatly improving installation efficiency and accuracy. When partial maintenance or replacement is required, specific modular components can be quickly disassembled, enabling convenient maintenance and component interchange, significantly reducing maintenance costs and downtime.

[0062] Referring to Figures 1 and 4, in one embodiment, baffles 226 are provided on both sides of the plate 221. The baffles 226 are inclined on both sides of the plate 221, and the baffles 226 on adjacent chain plate assemblies 220 at least partially overlap.

[0063] In this embodiment, the two baffles 226 are respectively fixedly connected to the two sides of the plate body 221 along the first direction 130, and the baffles 226 are inclined. That is, each baffle 226 is connected to the plate body 221 and has a certain width. In order to reduce the manufacturing process, it is set to be inclined relative to the second direction 140. The inclined arrangement is such that when multiple chain plate assemblies 220 are arranged sequentially along the conveying direction, the baffles 226 on two adjacent chain plate assemblies 220 can be at least partially overlapped at the joint.

[0064] For example, the inner wall of the baffle 226 at the front end of the subsequent chain plate assembly 220 may partially overlap the front of the outer wall of the rear end baffle 226 of the preceding chain plate assembly 220, or may be engaged by other forms of overlapping.

[0065] The baffles 226 form a continuous and more airtight lateral enclosure. The connected inclined baffles 226 can better guide the material and prevent it from bouncing and splashing towards the center after hitting the inner wall of the baffles 226 during the conveying process; the overlapping part of the adjacent baffles 226 effectively fills the gap at the connection of the chain plate assembly 220, greatly reducing the leakage of fine particulate material from the gap; it enhances the integrity of the side wall of the conveying channel and makes the operation more stable and continuous.

[0066] In summary, this application, by using standard I-beam main beams and sheet metal bending parts connected in a detachable manner, ensures the excellent load-bearing capacity and rigidity required for conveying large-flow, high-temperature materials, while also achieving rapid installation, convenient maintenance, and component interchangeability, significantly reducing the total life-cycle cost. The chain plate assembly 220 is equipped with a guide section, using a convex structure with different heights at both ends and a smooth arc-shaped upper surface to create a nested overlap between adjacent chain plates. This design not only ensures a continuous and smooth conveying surface, effectively preventing material jamming and leakage at joints, but also guides the material to gradually center itself during conveying, significantly improving the stability and continuity of the conveying process. The symmetrically arranged dual weighing guide rails 510, each supported by at least two weighing sensors 520, combined with a speed sensor and a leveling junction box, construct a stable, anti-eccentric load weighing platform that can automatically compensate for eccentric load effects and synchronously process gravity signals and real-time speed signals, thereby achieving high-precision, high-reliability dynamic continuous metering.

[0067] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
