Intelligent unloading trolley

Abstract

This invention provides an intelligent unloading trolley, relating to the field of industrial material conveying. It includes a trolley frame, a conveyor belt, idler rollers, and a set of rollers. The conveyor belt is wound between the rollers and the rollers in a continuous conveying path, which consists of an uphill section, an arched section, and a downhill section. The uphill section, through the arrangement of the rollers, has a lower center and higher sides, creating a gentle, concave slope for the conveyor belt. The arched section, through the arrangement of the rollers, has a higher center and gentler sides, creating a gentle, convex slope for the conveyor belt. This intelligent unloading trolley, through the cooperation of the uphill and arched sections, evenly distributes material that was originally concentrated in the middle to both sides, achieving autonomous material homogenization without the need for additional forced distribution. This avoids uneven distribution caused by uneven loading at the end of the material distribution process, eliminating the need for forced splitting at the rear end; simply guiding the flow is sufficient.

Description

Technical Field

[0001] This invention relates to the field of industrial material conveying, specifically to an intelligent unloading trolley. Background Technology

[0002] In the field of industrial material conveying, belt conveyors combined with intelligent unloading trolleys are the core equipment combination for achieving efficient material transfer and uniform distribution. Among them, intelligent unloading trolleys, as the key component for the final material distribution and output, are widely used in material distribution operations in industries such as mining, chemical, and building materials.

[0003] In existing technologies, for industrial operations requiring uniform material distribution on both sides, unloading trolleys generally employ a structure of single uphill conveying combined with a forced diversion plate at the end. When material falls onto the conveyor belt surface, its distribution is disordered and uneven. Under the continuous action of the uphill inclined conveyor, the tendency for material aggregation is exacerbated, resulting in areas with large accumulations of material, further widening the lateral distribution differences. Traditional equipment relies solely on the forced diversion structure at the end of the trolley to rigidly cut and guide the material, only passively diverting it at the discharge terminal, ultimately causing large deviations in discharge flow on both sides and uneven material distribution. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent unloading trolley that solves the problem of uneven material distribution at the end of the intelligent unloading trolley.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an intelligent unloading trolley, including a trolley frame, a conveyor belt, a roller group and a surface-enlarging wheel group, wherein the conveyor belt is wound between the surface-enlarging wheel group and the roller group in a continuous conveying path, and the conveying path is in sequence an uphill section, an arched section and a downhill section. The uphill section is designed with a structure that is low in the middle and high on both sides by using a wheel assembly with increased surface area, so that the conveyor belt forms a gentle concave slope on the uphill section. The arched section is arranged with rollers in a structure that is high in the middle and flat on both sides, so that the conveyor belt forms a gentle convex slope in the arched section. When the material is conveyed uphill, it gathers and accumulates in the middle. In the arched section in the middle, it is spread out laterally from the high position in the middle to the low positions on both sides by gravity, so that the material is evenly distributed before entering the end of the trolley for distribution.

[0006] Preferably, the bottom surface of the trolley frame is provided with a plurality of track wheels, and the two sides of the trolley frame are respectively provided with unloading ports.

[0007] Preferably, the trolley frame is further provided with a material distribution plate, which is triangular in shape and is set with unloading ports on both sides.

[0008] Preferably, the idler roller assembly is located inside the trolley frame, and the downhill section is located inside the trolley frame.

[0009] Preferably, the idler roller group includes a first idler roller, a second idler roller, and a third idler roller, and both ends of the first idler roller, the second idler roller, and the third idler roller are rotatably connected to the inner wall of the trolley frame. The first idler roller has a convex structure with a cross-section that is high in the middle and low on both sides.

[0010] Preferably, the cross-section of the conveyor belt is U-shaped, forming a groove structure.

[0011] Preferably, a support frame is provided on the right side of the trolley frame, the surface-enlarging wheel set is inclinedly disposed on the surface of the support frame, and the surface-enlarging wheel set is in contact with the bottom surface of the uphill section.

[0012] Preferably, a track frame is placed below the trolley frame, the surface of the track frame is provided with a track, and the track wheels are adapted to the track.

[0013] Preferably, the uphill section, the arched section and the downhill section all adopt a smooth arc transition, and the uphill section, the arched section and the downhill section form an integrated conveying structure that first gathers, then flattens and then stably distributes the material.

[0014] Preferably, the height of the arched section is gradually increased, transitioning smoothly from the middle to both sides, and the surfaces of the idler roller assembly and the conveyor belt are made of anti-slip and wear-resistant material.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This intelligent unloading trolley, through the cooperation of the uphill section and the arched section, evenly distributes the material that was originally concentrated in the middle to both sides, realizing the autonomous homogenization of the material. It can achieve uniform material distribution without the need for additional forced material distribution, thus avoiding uneven material distribution caused by uneven material loading at the end of the material distribution process.

[0016] This intelligent unloading trolley uses symmetrical unloading ports on both sides in conjunction with triangular material distribution plates to ensure uniform material distribution, avoiding situations where there is too much material on one side or no material on the other, thus meeting the needs of uniform material distribution in industrial production.

[0017] This intelligent unloading trolley, through the cooperation of the arched end and the downhill section, and the convex structure of the arched top in the middle section, allows the material to flow laterally and spread evenly. When distributing the material at the rear, there is no need to forcibly split it; it can simply be guided along the flow, thus avoiding material distribution deviation from the source.

[0020] like Figures 1-6 As shown, an intelligent unloading trolley includes a trolley frame 1, a conveyor belt 2, a roller group 3, and a surface-enlarging wheel group 4. The conveyor belt 2 is wound between the surface-enlarging wheel group 4 and the roller group 3 in a continuous conveying path. The conveying path is in sequence an uphill section 201, an arched section 202, and a downhill section 203.

[0021] The uphill section 201 is arranged with the surface-enhancing wheel set 4 in a structure that is low in the middle and high on both sides, so that the conveyor belt 2 forms a gentle concave slope in the uphill section 201. The uphill section 201 is set on the material feeding side. The uphill section 201 forms a support structure through the matching surface-enhancing wheel set 4. The overall layout is a trough shape with a low middle and high on both sides, so that the conveyor belt 2, which is sleeved on the outside, naturally fits into the support structure in the uphill section 201, forming a continuous and gentle concave slope. With the limiting structure on both sides of the concave slope, the material is guided by the slope and its own weight during the upward conveying process of the conveyor belt 2, and spontaneously gathers and gathers towards the middle of the conveyor belt 2, effectively preventing the material from running off course and scattering, and forming a concentrated material flow.

[0022] The arched section 202 is arranged with a high center and gentle sides by the idler roller group 3, so that the conveyor belt 2 forms a gentle convex slope in the arched section 202. The arched section 202 is connected to the discharge end of the uphill section 201. The arched section 202 is supported and shaped by the first idler roller 301. The first idler roller 301 adopts the arrangement of raising the center and gradually lowering the sides, presenting an overall structure with a high center and gentle descent on both sides. The conveyor belt 2 is laid in close contact with the contour of the idler roller group 3, so that the conveyor belt 2 in the arched section 202 forms a gentle transition convex slope without sharp corners or abrupt protrusions, ensuring that the belt deformation is soft.

[0023] When the material is conveyed through the uphill section 201, it gathers and accumulates in the middle. In the arched section 202 in the middle, it is spread out laterally from the high position in the middle to the low positions on both sides by gravity, so that the material is evenly distributed before entering the end of the trolley for distribution.

[0024] After the material is gathered and piled up in the uphill section 201 to form a concentrated material layer that is thick in the middle and thin on both sides, it is smoothly conveyed to the arched section 202 area. The middle position of the arched section 202 is higher than the sides. The material piled up in the middle of the belt is in a high and unstable state. The material particles and the material layer rely on their own gravity to spontaneously slide and flow slowly laterally from the high position in the middle to the low position on both sides. The material layer is laterally homogenized by gravity flow, which breaks the defect of material accumulation in the middle caused by single uphill conveying, and makes the originally concentrated material evenly distributed in the width direction of the conveyor belt 2.

[0025] The downhill section 203 connects to the discharge end of the arched section 202 and is used to smoothly transport the homogenized and leveled material layer to the material distribution position at the end of the trolley. After being evenly distributed by gravity in the arched section 202, the material layer has a uniform thickness and symmetrical distribution, and can directly enter the rear material distribution structure for diversion and unloading, avoiding uneven material distribution caused by uneven loading of incoming material or material accumulation in the middle.

[0026] The bottom surface of the trolley frame 1 is equipped with several track wheels 5. The track wheels 5 are arranged neatly along the bottom edge of the trolley frame 1. The track wheels 5 are rotatably connected to the trolley frame 1 through bearings to ensure smooth rolling. The trolley frame 1 is provided with discharge ports 6 on both sides. The discharge ports 6 are set on the two sides of the material distribution plate 7. The opening size is adapted to the material flow rate after distribution, so as to smoothly discharge the divided material outward, realizing synchronous and uniform unloading operation on both sides.

[0027] The trolley frame 1 is also equipped with a material distribution plate 7. The material distribution plate 7 is triangular in shape and is fixedly mounted at the center of the end of the downhill section 203 by bolts or welding. It is fixedly connected to the inner wall of the trolley frame 1 without loosening. The top of the triangular material distribution plate 7 faces the discharge direction of the conveyor belt 2, and the two sides are symmetrically inclined. The two sides are precisely facing the discharge ports 6 on both sides of the trolley frame 1. It can smoothly and equally guide the flat material layer after being homogenized by the arched section 202 to the discharge ports 6 on both sides, so as to achieve equal distribution of material on both sides.

[0028] The idler roller group 3 is fixedly assembled in the internal cavity of the trolley frame 1 by a bracket. The positions of each idler roller in the idler roller group 3 are relatively fixed, and the axis of each idler roller is parallel to the width direction of the conveyor belt 2, providing stable support and contour shaping for the conveyor belt 2 throughout the process. The downhill section 203 is completely housed in the internal cavity of the trolley frame 1 and does not exceed the frame range. The cavity structure of the trolley frame 1 forms a closed protective space, which effectively reduces the entry of external dust and debris into the conveying area and interferes with the material conveying. At the same time, it ensures that the material after being homogenized by the arched section 202 is smoothly conveyed inward to the distribution plate 7.

[0029] The idler roller group 3 includes a first idler roller 301, a second idler roller 302, and a third idler roller 303. Both ends of the first idler roller 301, the second idler roller 302, and the third idler roller 303 are rotatably connected to the inner wall of the trolley frame 1 to ensure that the idler roller group 3 can rotate synchronously with the conveyor belt 2 and reduce the friction loss between the belt and the idler roller group 3. The first idler roller 301 is arranged corresponding to the arched section 202, and its cross-section is a convex shape with a high middle and low sides. It is used to support the conveyor belt 2 to form the convex slope of the arched section 202. The second idler roller 302 and the third idler roller 303 are arranged corresponding to the downslope section 203. They are used to support the conveyor belt 2 to form the corresponding slope and ensure the transmission of the conveyor belt 2. The first idler roller 301 has a convex structure with a cross-section that is high in the middle and low on both sides.

[0030] The conveyor belt 2 is made of wear-resistant and tensile-resistant rubber material. It is closed and wrapped around the outside of the roller group 4 and the idler group 3, and can closely fit the contour of the idler group 3 and the roller group 4. In particular, the conveyor belt 2 at the uphill section 201 has a regular concave cross section under the support of the roller group 4, forming a stable trough-shaped material gathering structure, which further improves the material gathering effect and prevents the material from running off course or scattering during the uphill conveying process.

[0031] A support frame 8 is provided on the right side of the trolley frame 1. The surface-enhancing wheel set 4 is inclinedly set on the surface of the support frame 8, and the surface-enhancing wheel set 4 is in contact with the bottom surface of the uphill section 201.

[0032] A support frame 8 is fixedly welded to the right outer wall of the trolley frame 1. The support frame 8 is set at an inclination, forming a stable triangular support structure with the outer wall of the trolley frame 1 to ensure support strength. The surface-enhancing wheel set 4 is fixedly and installed at an inclination on the surface of the support frame 8 by bolts. The outer edge of the wheel of the surface-enhancing wheel set 4 is in close contact with the bottom surface of the conveyor belt 2 of the uphill section 201 to support the conveyor belt 2 of the uphill section 201, and at the same time assist the conveyor belt 2 in tensioning to ensure that it does not slip or loosen during the conveying process.

[0033] A track frame 9 is placed under the trolley frame 1. The surface of the track frame 9 is provided with a track 10, and the track wheels 5 are adapted to the track 10. The track wheels 5 under the trolley frame 1 roll and cooperate with the surface of the track 10. The track wheels 5 and the track 10 are precisely matched in size, which can drive the trolley frame 1 to move smoothly back and forth along the track 10, so as to realize the fixed-point intelligent unloading of different workstations.

[0034] The uphill section 201, the arched section 202, and the downhill section 203 all adopt a smooth arc transition, with no hard angles or abrupt protrusions at the transition points, so that the conveyor belt 2 can transition smoothly, avoid stress concentration at the connection point, and effectively reduce fatigue wear of the conveyor belt 2. The uphill section 201, the arched section 202, and the downhill section 203 form an integrated conveying structure that first gathers, then flattens, and then stably distributes materials.

[0035] The height of the arched section 202 is gradually increased, transitioning smoothly from the middle to both sides. This ensures a smooth transition of the convex slope formed by the conveyor belt 2, allowing the material to slide smoothly during lateral distribution and preventing material impact, spillage, or uneven distribution due to sudden changes in height. The surfaces of the idler roller group 3 and the conveyor belt 2 are designed with anti-slip and wear-resistant structures. The idler roller group 3 is coated with a wear-resistant and anti-slip coating, and the outer surface of the conveyor belt 2 is provided with anti-slip textures. This not only enhances the friction between the idler roller group 3 and the conveyor belt 2, preventing belt slippage, but also improves the wear resistance of the components, extends the service life of the equipment, and prevents the material from sliding relative to the belt during conveying, ensuring uniform material distribution and conveying stability.

[0036] Before the equipment starts, the track-walking wheels 5 are precisely matched with the track 10 on the ground track frame 9. The trolley frame 1 is stably supported by the track-walking wheels 5 and can move back and forth along the track 10 under the drive of the walking drive component to be positioned at the designated unloading station. The conveyor belt 2 is closed and surrounded on the outside of the surface-enhancing wheel group 4 and the idler group 3. The surface-enhancing wheel group 4 is fixedly supported by the inclined support frame 8 on the right side of the trolley frame 1. Together with the idler group 3, it realizes the tension and limit of the conveyor belt 2, ensuring that the belt does not slip or loosen during operation. The idler group 3 is fixedly assembled inside the trolley frame 1 to provide full support for the conveyor belt 2 and shape the corresponding slope, thus completing all preparations before material conveying.

[0037] Material enters the uphill section 201 of conveyor belt 2 from the feed end. This section forms a trough-shaped support structure with a low center and high sides through inclined wheel sets 4 on both sides, causing the conveyor belt 2 to conform to form a gentle concave slope (the cross-section is U-shaped). During the upward conveying process of the material with conveyor belt 2, under the combined influence of the limiting effect of the concave slope on both sides and the weight of the material itself, the material will spontaneously gather and concentrate towards the center of conveyor belt 2, forming a concentrated material flow, which effectively prevents the material from deviating or scattering during the uphill process.

[0038] After being gathered in the uphill section 201, the material smoothly enters the connecting arched section 202 along the conveyor belt 2. This section is designed with a structure where the idler group 3 (especially the first idler 301 corresponding to the arched section 202, which has a convex shape with a high center and low sides) is arranged in a way that is high in the center and gently descends on both sides. The height of the arched section 202 is gradually set, gradually decreasing from the center to both sides, so that the conveyor belt 2 fits together to form a smooth transition of the convex slope, without sharp corners or abrupt protrusions.

[0039] At this time, the material piled up in the middle of the conveyor belt 2 is in a high and unstable state. Under the action of its own gravity, the material particles and material layer will spontaneously slide and flow slowly from the high position in the middle to the low position on both sides. At the same time, the surfaces of the idler roller group 3 and the conveyor belt 2 are both made of anti-slip and wear-resistant structure, which effectively enhances the friction between the idler roller group 3 and the conveyor belt 2, prevents the belt from slipping, and avoids the material from sliding relative to the belt during the conveying process.

[0040] The homogenized and leveled material layer is conveyed by conveyor belt 2 into the connecting downhill section 203. The downhill section 203 is completely housed inside the trolley frame 1 and descends smoothly with the support of idler roller group 3, so that the homogenized material is steadily conveyed to the material distribution position at the end of the trolley, avoiding the material layer from becoming disordered again during the conveying process.

[0041] When the homogenized material is conveyed to the distribution plate 7, the distribution plate 7 will guide the flat material layer to both sides in a stable and equal manner, so that the material flows into the two symmetrically arranged discharge ports 6 on the left and right sides respectively, realizing the synchronous and uniform discharge operation on both sides. The opening size of the discharge port 6 is matched with the material flow rate after distribution, ensuring that the material can be discharged out smoothly.

[0042] During the unloading process, the track wheels 5 at the bottom of the trolley frame 1 can move smoothly back and forth along the track 10 on the track frame 9 under the drive of the drive component, realizing fixed-point intelligent unloading at different workstations. The track wheels 5 and the track 10 are precisely matched in size, and the wheel body and the trolley frame 1 are connected by bearing rotation to ensure smooth movement and meet the needs of multi-station and continuous unloading in industrial production.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
