Description

Technical Field

[0001] This utility model relates to the field of unmanned transport vehicle technology, and in particular to an unmanned bulk grain transport vehicle. Background Technology

[0002] In agricultural production, grain storage, and port transshipment, the transshipment of bulk grain is a crucial link in ensuring the efficiency of grain circulation. Traditional bulk grain transshipment mainly relies on manual operation of ordinary transport vehicles and equipment.

[0003] Traditional bulk grain transportation relies on manual operation, requiring full human intervention in the transportation and unloading process. This is not only labor-intensive but also inefficient. During unloading, manual operation of machinery to tilt the hopper or open the discharge port makes it difficult to precisely control the force and rhythm of the operation, often resulting in spillage and splashing of bulk grain, leading to grain loss. Furthermore, existing transportation equipment lacks integrated weighing functions, requiring additional equipment to measure the weight of bulk grain before and after loading, increasing operational steps and time costs.

[0004] To address this, we designed an unmanned bulk grain transport vehicle. Utility Model Content

[0005] This utility model discloses an unmanned bulk grain transfer vehicle, which aims to solve the technical problems of unmanned transfer vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An unmanned bulk grain transport vehicle includes an unmanned vehicle body, a transport vehicle shell fixedly connected to the upper surface of the unmanned vehicle body, and a grain transport component disposed inside the transport vehicle shell. The grain transport component includes two limiting mounting slots on the upper surface of the unmanned vehicle body. The inner wall of the limiting mounting slot is rotatably connected to a rotating support block. The top of the two rotating support blocks is fixedly connected to a grain transport box. The inner wall of the transport vehicle body is provided with a rectangular slot. A drive screw is rotatably connected between the inner bottom wall and the inner top wall of the rectangular slot. A drive block is threadedly connected to the surface of the drive screw. A movable push rod is rotatably connected to the surface of the drive block. The end of the movable push rod away from the drive block is rotatably connected to the surface of the grain transport box.

[0007] In a preferred embodiment, the interior of the transfer vehicle housing is provided with a motor mounting slot, the inner wall of which is fixedly connected to a drive motor, the rotating shaft of which is fixedly connected to a worm gear, the top end of which extends into the interior of the motor mounting slot and is fixedly connected to a worm wheel, the position of which corresponds to that of the worm gear, and the worm gear meshes with the worm wheel.

[0008] In a preferred embodiment, the back of the grain container is provided with an unloading assembly, which includes a strip-shaped protective shell fixedly connected to the back of the grain container. A lifting motor is fixedly connected to the inner top wall of the strip-shaped protective shell, and a lifting screw is fixedly connected to the rotating shaft of the lifting motor.

[0009] In a preferred embodiment, the lifting screw is threadedly connected to a movable rod, and a discharge baffle is fixedly connected to the bottom end of the movable rod. A rectangular discharge port is provided on the back of the grain transport box, and the position of the discharge baffle corresponds to the rectangular discharge port, and the size of the discharge baffle matches the rectangular discharge port.

[0010] In a preferred embodiment, two L-shaped limiting plates are symmetrically fixedly arranged on the back of the grain transport box. The two L-shaped limiting plates are symmetrically distributed on the left and right sides of the discharge baffle, and the discharge baffle is slidably connected to the inner surface of the L-shaped limiting plates respectively.

[0011] In a preferred embodiment, a weighing base plate is fixedly connected to the inner bottom wall of the grain transport box, a weighing sensor is fixedly connected to the lower surface of the grain transport box, the input end of the weighing sensor is fixedly connected to the bottom of the weighing base plate, and a limiting groove matching the weighing sensor is provided on the surface of the unmanned vehicle body.

[0012] In a preferred embodiment, the upper surface of the grain container is provided with a feed inlet, the inner wall of the feed inlet is provided with a sealing cover, and sealing strips are fixedly connected around the sealing cover.

[0013] As can be seen from the above, the unmanned bulk grain transfer vehicle provided by this utility model has the following technical effects.

[0014] Firstly, by setting up grain conveying and unloading components, the entire process of bulk grain transfer and unloading is automated. In the grain conveying component, the drive motor drives the drive screw to rotate through a worm gear, which in turn drives the drive block to move up and down. This, in turn, pushes the grain conveying box to rotate around the rotating support block through a movable push rod. In conjunction with the unloading component, the lifting motor drives the lifting screw to rotate, which causes the discharge baffle to slide along the L-shaped limit plate to open the rectangular discharge port. Unloading can be completed without manual intervention, greatly improving the transfer efficiency. The lifting stroke of the discharge baffle is controlled by the lifting motor to ensure that the unloading speed is stable and controllable, avoiding spillage and splashing during bulk grain unloading, reducing bulk grain loss, and facilitating adjustment of the discharge speed.

[0015] Secondly, the weighing base plate inside the grain container works in conjunction with the weighing sensor to monitor the weight of the bulk grain in the container in real time, making it convenient for staff to keep track of the amount of grain transferred, ensuring the accuracy of the weighing data, and facilitating the measurement and management of the transfer operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 An unmanned bulk grain transport vehicle includes an unmanned vehicle body 1, a transport vehicle shell 2 fixedly connected to the upper surface of the unmanned vehicle body 1, and a grain transport component 3 disposed inside the transport vehicle shell 2.

[0024] The grain transport component 3 includes two limiting mounting slots 301 on the upper surface of the unmanned vehicle body 1. The inner wall of the limiting mounting slot 301 is rotatably connected to a rotating support block 302. The top of the two rotating support blocks 302 is fixedly connected to a grain transport box 303. The upper surface of the grain transport box 303 is provided with a feed inlet. A sealing cover plate 314 is placed on the inner wall of the feed inlet. Sealing strips are fixedly connected around the sealing cover plate 314.

[0025] It is worth noting that when the sealing cover 314 is placed over the feed inlet, the sealing strip fits tightly against the inner wall of the feed inlet, forming a good sealing effect. This effectively isolates external dust, moisture and other impurities, preventing the bulk grain from getting damp, contaminated or spilled during transportation, ensuring the quality of the bulk grain, and preventing the leakage of bulk grain from affecting the surrounding environment.

[0026] The grain container 303 is provided with a unloading assembly 4 on the back. The unloading assembly 4 includes a strip-shaped protective shell 401 fixedly connected to the back of the grain container 303. A lifting motor 402 is fixedly connected to the inner top wall of the strip-shaped protective shell 401. A lifting screw 403 is fixedly connected to the rotating shaft of the lifting motor 402.

[0027] The lifting screw 403 is threadedly connected to a moving rod 404. The bottom end of the moving rod 404 is fixedly connected to a discharge baffle 405. A rectangular discharge port 406 is opened on the back of the grain transport box 303. The position of the discharge baffle 405 corresponds to the rectangular discharge port 406, and the size of the discharge baffle 405 matches the rectangular discharge port 406.

[0028] Two L-shaped limiting plates 407 are symmetrically fixed on the back of the grain container 303. The two L-shaped limiting plates 407 are symmetrically distributed on the left and right sides of the discharge baffle 405, and the discharge baffle 405 is slidably connected to the inner surface of the L-shaped limiting plates 407 respectively.

[0029] It is worth noting that the position of the discharge baffle 405 corresponds to that of the rectangular discharge port 406, and its size matches that of the rectangular discharge port 406, allowing it to completely cover or open the rectangular discharge port 406. To ensure the stability of the discharge baffle 405 during its lifting and lowering process, two L-shaped limiting plates 407 are symmetrically fixed on the back of the grain transport box 303. The two L-shaped limiting plates 407 are located on the left and right sides of the discharge baffle 405, respectively. The left and right edges of the discharge baffle 405 are slidably connected to the inner surface of the L-shaped limiting plates 407. Through the limiting effect of the L-shaped limiting plates 407, the discharge baffle 405 is prevented from shifting or tilting during its lifting and lowering, ensuring that the discharge baffle 405 accurately aligns with the rectangular discharge port 406. This ensures both a sealing effect and a smooth and controllable unloading process, preventing spillage and splashing of loose grain that could cause losses.

[0030] The inner wall of the transport vehicle housing 2 is provided with a rectangular groove 304. A drive screw 305 is rotatably connected between the inner bottom wall and the inner top wall of the rectangular groove 304. A drive block 306 is threadedly connected to the surface of the drive screw 305. A movable push rod 307 is rotatably connected to the surface of the drive block 306. The end of the movable push rod 307 away from the drive block 306 is rotatably connected to the surface of the grain transport box 303.

[0031] The interior of the transfer vehicle housing 2 is provided with a motor mounting slot 308. A drive motor 309 is fixedly connected to the inner wall of the motor mounting slot 308. A worm gear 310 is fixedly connected to the rotating shaft of the drive motor 309. The top end of the drive screw 305 extends into the interior of the motor mounting slot 308 and is fixedly connected to a worm wheel 311. The position of the worm wheel 311 corresponds to that of the worm gear 310, and the worm gear 310 meshes with the worm wheel 311.

[0032] It is worth noting that the rotational power of the drive motor 309 is transmitted to the drive screw 305 through the transmission cooperation of the worm 310 and the worm wheel 311, realizing the smooth transmission of power and the conversion of direction. This transmission structure not only has high power transmission efficiency, but also effectively ensures the stability of the grain container 303 during the flipping process, avoids flipping too fast or jamming, and improves the safety of the transfer process.

[0033] A weighing base plate 312 is fixedly connected to the inner bottom wall of the grain transport box 303, and a weighing sensor 313 is fixedly connected to the lower surface of the grain transport box 303. The input end of the weighing sensor 313 is fixedly connected to the bottom of the weighing base plate 312, and a limiting groove matching the weighing sensor 313 is opened on the surface of the unmanned vehicle body 1.

[0034] Working principle: When using this unmanned bulk grain transfer vehicle, first open the sealing cover 314, and load bulk grain into the grain container 303 through the feed inlet on the upper surface of the grain container 303. During the loading process, the weighing base plate 312 transfers the weight of the bulk grain to the weighing sensor 313, which collects the weight data in real time and feeds it back to the operator. After loading is completed, start the unmanned vehicle body 1, which travels to the designated unloading location according to the preset path. Upon arrival at the destination, start the drive motor 309. The rotating shaft of the drive motor 309 drives the worm gear 310 to rotate. The worm gear 310 meshes with the worm wheel 311, driving the drive screw 305 to rotate in the rectangular groove 304. When the drive screw 305 rotates, the drive block 306 moves up and down along the axial direction of the drive screw 305. The drive block 306 drives one end of the movable push rod 307 to move, and the movable push rod 307 pushes the grain container 303 to rotate around the rotation axis of the rotating support block 302, causing the grain container 303 to tilt. Then, the lifting motor 402 is started. The rotation axis of the lifting motor 402 drives the lifting screw 403 to rotate, and the moving rod 404 moves upward along the axial direction of the lifting screw 403, causing the discharge baffle 405 to slide upward synchronously, and the rectangular discharge port 406 gradually opens. Since the grain container 303 is in an tilted state, the loose grain inside flows out smoothly through the rectangular discharge port 406 under the action of gravity, completing the unloading. During the unloading process, the opening degree of the discharge baffle 405 can be adjusted by controlling the operation of the lifting motor 402, thereby controlling the unloading speed; the tilting angle of the grain container 303 can be adjusted by controlling the operation of the drive motor 309, thereby controlling the unloading speed.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
