Description

Technical Field

[0001] This utility model relates to the field of grain transportation technology, specifically to a grain discharge assembly for a grain transport vehicle. Background Technology

[0002] Trains and freight cars, as the main carriers of grain transportation, play an indispensable role in the grain circulation process. Trains, with their advantages of large capacity and long-distance transportation, ensure the allocation of grain across regions; freight cars, with their flexibility and convenience, play an important role in short-distance grain transportation within regions. Together, they constitute a key transportation network for grain from production areas to sales areas.

[0003] However, the shape and structure of train carriages and freight cars often lead to frequent grain residue during unloading at designated locations. Structurally, train carriages are mostly rectangular, with rounded corners, joints, and gaps at the bottom, making it difficult for unloading devices to completely cover these areas. Freight car cargo holds have similar problems, especially at the junctions between the bottom and side walls and the sealing edges of the cargo doors. Due to structural design limitations, grain easily accumulates and remains in these areas. When the grain is unloaded, most of it can be discharged by gravity or mechanical means, but the remaining grain adheres firmly to these structural dead zones and cannot be smoothly unloaded with the main flow.

[0004] Grain residue not only wastes grain resources but also causes numerous inconveniences for subsequent operations. To clean up this residue, workers must handle it separately, often needing to enter the cargo compartments or warehouses and manually sweep with brooms and shovels. This significantly increases their workload and prolongs the operation time. Simultaneously, this additional cleaning step severely slows down the overall grain disposal process, affecting the turnaround efficiency of transport vehicles. During peak grain transport periods, the inability of transport vehicles to quickly unload and clean up can disrupt subsequent transport plans, creating a chain reaction. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the difficulty and low efficiency of cleaning residual grain in the carriage under the existing technology, and to provide a grain discharge component for grain transport carriages.

[0006] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a grain discharge assembly for a grain transport vehicle, which has a discharge cylinder that can be installed at the bottom of the vehicle for discharging grain, and a material support component inside the discharge cylinder. The material support component can cooperate with the bearing component to cover the bottom of the vehicle and guide the grain into the discharge cylinder for discharge. The load-bearing component includes multiple rigid plates, a flexible layer connecting adjacent rigid plates, and an elastic fabric connecting the outer edge of the rigid plates and the inner wall of the carriage; the flexible layer is arranged along the radial direction from the discharge cylinder to the inner wall of the carriage. The material support component includes multiple lifting rods connected to the bearing component and an electric push rod located inside the discharge cylinder; The lifting rod is hinged to a fulcrum on the bottom surface of the carriage, and the fulcrum is positioned away from the discharge cylinder. The electric push rod can drive the ends of multiple lifting rods to cooperate with the lever structure formed by the fulcrum support to tilt the outer edges of multiple rigid plates toward the discharge cylinder.

[0007] As a further optimization of the grain discharge assembly for a grain transport vehicle of this utility model: two electric push rods are provided, and the two electric push rods are located in the storage slot opened near the bottom of the vehicle body of the discharge cylinder.

[0008] As a further optimization of the grain discharge assembly for a grain transport vehicle of this utility model: the electric push rod drives a linkage ring that is slidably disposed in the storage tank, and four pull columns that are hinged to the lifting rod are fixedly disposed on the linkage ring.

[0009] As a further optimization of the grain discharge assembly for a grain transport vehicle of this utility model: the storage tank is provided with two protective cloths, and the two sides of the linkage ring are respectively fixedly connected to the two protective cloths.

[0010] As a further optimization of the grain discharge assembly for a grain transport vehicle of this utility model: the lifting rod and the bearing component are connected together by screws through threaded holes.

[0011] As a further optimization of the grain discharge assembly for a grain transport vehicle of this utility model: the fulcrum component includes a fulcrum frame hinged to the lifting rod, and a fixed seat that can be adsorbed onto the bottom of the vehicle is fixedly provided at the bottom of the fulcrum frame.

[0012] As a further optimization of the grain discharge assembly for a grain transport vehicle of this utility model: a blocking component is inserted into the discharge port of the discharge cylinder. The blocking component includes a blocking plate that is slidably disposed on the discharge cylinder. The blocking plate can block the discharge port of the discharge cylinder. A groove is opened at the point where the blocking plate passes through the discharge cylinder. The groove is matched with a rotating block that is rotatably disposed on the discharge cylinder.

[0013] As a further optimization of the grain discharge assembly for a grain transport vehicle of this utility model: the discharge cylinder is L-shaped, and the discharge port of the discharge cylinder is located away from the vehicle body.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a carrier component supported by the truck bed to support the grain stored inside. Furthermore, a material-supporting component that tilts the carrier component towards the discharge cylinder helps workers remove any remaining grain that may have accumulated in the truck bed due to insufficient height. Specifically, an electric push rod rotates a lifting rod, raising the edge of the carrier component connected to the lifting rod to form an inclined surface towards the discharge cylinder. This causes the carrier component to bend and guide the remaining grain, assisting workers in removing it. Attached Figure Description

[0016] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0017] like Figure 2-4 As shown, a grain discharge assembly for a grain transport vehicle 1 is provided. The vehicle 1 is designed with a discharge cylinder 5 that can be installed at the bottom of the vehicle 1 and communicates with the interior of the vehicle 1. A material support component 3 is disposed inside the discharge cylinder 5. On the side of the material support component 3 facing away from the bottom of the vehicle 1, a support component 2 is provided, covering the bottom of the vehicle 1, and the edge of the support component 2 is connected to the edge of the vehicle 1. Its working principle is that when the grain in the vehicle 1 is discharged through the discharge cylinder 5, if some grain remains on the support component 2, the material support component 3 will activate, lifting the support component 2 and tilting it towards the discharge cylinder 5. This action causes the remaining grain to also tilt towards the discharge cylinder 5, thereby assisting the operators in discharging the remaining grain from the discharge cylinder 5, reducing the workload of the operators in sorting and collecting the remaining grain.

[0018] like Figure 1As shown, the carrier 2 includes multiple rigid plates 201 and two elastic fabrics 202. The multiple rigid plates 201 are connected together by a flexible layer 203, which is arranged radially along the discharge cylinder 5 towards the vertical inner wall of the carriage 1. The multiple rigid plates 201 are connected to the discharge cylinder 5 and the vertical inner wall of the carriage 1 by the elastic fabrics 202. The flexible layer 203 can be made of flexible, foldable metal or smooth rubber, thereby assisting the multiple rigid plates 201 to fold towards the discharge cylinder 5, thus guiding the grain out. The rigid plates 201 can be made of metal sheet to maintain their rigid structure. Specifically, there are two rigid plates 201, and the center of the two rigid plates 201 is connected to the vertically arranged flexible layer 203. The elastic fabric 202 can be made of nylon woven high abrasion-resistant fabric. The rigid plates 201 and the elastic fabric 202 or the flexible layer 203 can be fixed together with screws.

[0019] like Figure 2 and Figure 3 As shown, the specific structure of the material support component 3 includes a storage tank 307 located near the bottom of the carriage 1 in the discharge cylinder 5. The storage tank 307 contains two electric push rods 304 and a linkage ring 303 driven by the two electric push rods 304 for vertical displacement. Pulling posts 305 are fixed at each of the four corners of the linkage ring 303. These pulling posts 305 extend out of the discharge cylinder 5 and their ends are hinged to the lifting rods 301. The lifting rods 301 are rotatably connected to a fulcrum 302 located on the carriage 1, and the fulcrum 302 is positioned away from the discharge cylinder 5 to reduce the force required to pull the lifting rods 301 by the electric push rods 304. The four material support rods 301 are divided into two groups, each connected to one of the two rigid plates 201. When it is necessary to remove grain residue from the bearing component 2, the electric push rods 304 drive the linkage ring 303, causing the four pulling posts 305 to move downwards. The downward displacement of the four pulling columns 305 drives the four lifting rods 301. The lever structure formed by the fulcrum 302 tilts the four lifting rods 301 towards the center of the discharge cylinder 5. This tilting of the four lifting rods 301 towards the center of the discharge cylinder 5 causes the edges of the corresponding two rigid plates 201 to pull the elastic cloth 202 upwards, simultaneously compressing and folding the flexible layer 203, thus forming an inclined surface towards the discharge cylinder 5. This concentrates the residual grain at the lower position of the inclined surface formed by the rigid plates 201, thereby assisting the operator in discharging the residual grain. Specifically, the bearing member 2 and the lifting rods 301 are fixedly connected together by screws through threaded holes 306.

[0020] Multiple rigid plates 201 near the inner edge of the discharge cylinder 5 essentially form a virtual axis of rotation around the discharge cylinder. Since the inner side of the rigid plates 201 is indirectly and movably connected to the periphery of the discharge cylinder 5 via a flexible layer 203, when the outer edge of the lifting rod 301 is pulled downwards, according to the lever principle, the part connected to the rigid plate 201 will gain an upward displacement, thereby forcing the rigid plate 201 to rotate around this virtual axis on its inner side, causing its outer edge to lift up, ultimately forming a slope inclined towards the discharge cylinder 5.

[0021] The storage slot 307 is also provided with a wiring harness hole 308 on the side near the center of the carriage 1, so that the operator can pass the corresponding control line through and connect it to the electric push rod 304 to control the electric push rod 304 and provide power to the electric push rod 304 to make the electric push rod 304 move.

[0022] During the discharge process, the vertical movement of the electric push rod 304 is adjusted according to the amount of residual grain. Initially, if there is a large amount of residual grain, the vertical movement of the electric push rod 304 will be relatively small. As the amount of residual grain gradually decreases, the downward vertical displacement of the electric push rod 304 will gradually increase. This maintains the stability of the structure, avoids structural damage, and simultaneously achieves rapid discharge of residual grain.

[0023] like Figure 4 As shown, the fulcrum 302 includes a fulcrum frame 3021 hinged to the lifting rod 301. A fixed seat 3022 is provided at the bottom of the fulcrum frame 3021. The fixed seat 3022 allows operators to easily position the fulcrum frame 3021 in a suitable position using screws, thus providing sufficient leverage for the electric push rod 304 to repeatedly deflect the lifting rod 301. To further optimize the discharge effect, a protective cloth 4 is fixedly connected to the inner walls of the storage tank 307 on both the upper and lower sides. The upper and lower sides of the linkage ring 303 are respectively connected to the other ends of the two protective cloths 4, thereby preventing grain from entering the storage tank 307 and affecting the vertical movement of the electric push rod 304. The side of the storage tank 307 facing the inside of the discharge cylinder 5 is sealed by a complete, seamless annular protective cloth 4. The outer edge of the annular protective cloth 4 is fixedly connected to the inner wall of the storage tank 307, and the inner edge of the protective cloth 4 is fixedly connected to the side of the linkage ring 303, thus forming a closed, pleated sealing structure. When the linkage ring 303 moves up and down, the protective cloth 4 extends and contracts accordingly, which can prevent grain dust from entering the storage tank 307 to the greatest extent. The discharge cylinder 5 itself is designed with an L-shaped structure, and its bent section is set away from the carriage 1 to ensure that the grain can be stably discharged out of the carriage 1.

[0024] At the end of the discharge cylinder 5 facing away from the carriage 1, a blocking element 6 is installed to control the discharge state of the discharge cylinder 5. The blocking element 6 includes a blocking plate 601 that can be inserted into and close the discharge cylinder 5 to prevent grain from being discharged from the discharge cylinder 5. At the same time, a groove 602 is provided at the end of the blocking plate 601 that protrudes from the discharge cylinder 5, so that the operator can easily pull out the blocking plate 601 to open the discharge. In order to reduce the probability of the blocking plate 601 coming off under the pressure of the grain, a rotating block 603 is also rotatably provided at the corresponding position of the groove 602. When the blocking plate 601 is inserted to block the discharge cylinder 5, the rotating block 603 will engage with the groove 602 and cooperate with the pressure of the grain to prevent the blocking plate 601 from easily coming off the discharge cylinder 5, thus preventing the grain from being discharged and lost at will.

[0025] In this embodiment, the specific model, working method and control method of the electric push rod 304 should be understood as existing technology. Depending on the required force, the electric push rod 304 can also be replaced with a hydraulic rod, as long as it can pull the lifting rod 301 to deflect.

[0026] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
