Description

Technical Field

[0001] This utility model relates to the field of AGV technology, specifically to an outdoor grain transfer AGV. Background Technology

[0002] Currently, grain transportation is mainly carried out by manually driven grain trucks or manually pushed carts. When carrying out transportation within a small area (such as within an industrial park), manual transportation has disadvantages such as high labor intensity, harsh working conditions, and low work efficiency.

[0003] Automated Guided Vehicles (AGVs) are industrial vehicles that load goods automatically or manually, travel automatically along a set route or tow a cargo trolley to a designated location, and then load and unload goods automatically or manually. Most AGVs are used indoors and are not very suitable for transporting grain outdoors. Therefore, there is a need for a grain transport AGV suitable for outdoor scenarios. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides an outdoor grain transfer AGV that enables the transfer of outdoor grain in logistics parks, improving the working environment for manual labor, reducing labor intensity, and providing high-quality material transfer safety and efficiency.

[0005] Specifically, this utility model is implemented as follows:

[0006] An outdoor grain transfer AGV includes an AGV body and a hopper, wherein the AGV body is equipped with an outdoor navigation system, and further includes:

[0007] A hydraulic tilting assembly, mounted on the AGV body, is used to tilt the hopper; the hopper's discharge side is equipped with a first opening and closing door for discharging material.

[0008] A rain-shielding component is disposed above the hopper. The rain-shielding component is a retractable structure used to shield the hopper.

[0009] Furthermore, the rain-shielding assembly includes:

[0010] A retractable tarpaulin is installed on the hopper;

[0011] A track is located at the top of the hopper, and the retractable tarpaulin is located on both sides within the track and moves along the track.

[0012] Furthermore, the hopper is provided with a first cavity and a second cavity, which are separated by a second opening and closing door. The hopper is provided with an opening and closing drive assembly for opening and closing the second opening and closing door.

[0013] Furthermore, the opening / closing drive component includes:

[0014] A driving component is disposed on the hopper and located on the side away from the first cavity;

[0015] The connecting cable is connected to the drive unit at one end and to the second opening and closing door after passing through the hopper at the other end. When the connecting cable is in a tensioned state, it pulls the second opening and closing door, and the second opening and closing door is in a closed state.

[0016] Furthermore, a conduit is provided inside the second cavity, and the connecting cable is located inside the conduit.

[0017] Furthermore, the AGV body is provided with a locking hook on the side near the first opening and closing door. The locking hook is configured as a rotating structure for opening and closing the first opening and closing door.

[0018] Furthermore, the AGV body adopts a bridge-type suspension.

[0019] Compared with the prior art, the working principle and beneficial effects of this utility model are as follows:

[0020] (1) The outdoor grain transfer AGV provided by this utility model uses a tilting method for unloading, which can quickly pour out the grain in the hopper and improve the efficiency of transfer and unloading.

[0021] (2) A retractable rain shield is installed above the hopper to shield the grain in the hopper and avoid the problem of the grain being affected by weather such as rain or sun exposure during transportation.

[0022] (3) The hopper is designed with separate compartments, and the opening and closing of the doors of each compartment are independently controlled, which can realize the simultaneous transfer of different grains. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1-2 As shown, this embodiment discloses an outdoor grain transfer AGV, including an AGV body 1, a hopper 2, and a rain shelter assembly 4. The AGV body 1 includes a frame, a bridge suspension 11, a driving unit, and an outdoor navigation system. The driving unit is used to realize the basic walking function of the AGV. The outdoor navigation system is a conventional AGV outdoor navigation system, which will not be described in detail here. The bridge suspension 11 has a simple structural design, high rigidity and stability, and can effectively reduce vehicle rollover and bumping, improving driving stability.

[0038] The hopper 2 is mounted on the frame via a hinge structure. The hydraulic tilting assembly 3 is mounted on the frame and connected to the hopper 2. The hydraulic tilting assembly 3 pushes the hopper 2 to rotate around the hinge between the hopper 2 and the frame, thereby unloading the material.

[0039] The hopper 2 has a first cavity 21 and a second cavity 22, which are separated by a second opening / closing door 24. Above the second opening / closing door 24 is a fixed baffle 25. The upper part of the second opening / closing door 24 is hinged to the baffle 25, and the lower part is connected to an opening / closing drive assembly, which drives its opening and closing. Figure 3-7As shown, the outlet end of the first cavity 21 is a hinged first opening and closing door 23. The AGV body 1 below the first opening and closing door 23 is equipped with a chain-type opening and closing structure, similar to that of a conventional dump truck, for opening and closing the first opening and closing door 23. This structure mainly consists of a chain 232 and a locking hook 231. When unloading is required, the hopper 2 tilts backward under the action of the hydraulic tilting assembly 3. During this process, the distance between the locking hook 231 and the lower fixing point of the chain 232 decreases, causing the locking chain 232 to loosen. Due to the loosening of the chain 232, the rear door locking hook 231 no longer locks the rear door, but is pushed open under the weight of the rear door, thus achieving unloading. After unloading, the hopper 2 falls back to its original position under gravity. At this time, the rear door locking hook 231, under the tension of the chain 232, presses and closes the first opening and closing door 23, completing the closure of the first opening and closing door 23.

[0040] like Figure 8 As shown, the opening and closing drive assembly includes two sets of hydraulic cylinders 241 and a connecting cable 242. The hydraulic cylinders 241 are located on the side of the hopper near the front of the vehicle, and the end of their piston rods is fixedly connected to the connecting cable 242. The connecting cable 242 extends downwards into the hopper, is guided by a guide wheel into the second cavity 22, and is fixedly connected to the second opening and closing door 24. When the hydraulic cylinders 241 are in the retracted state, the connecting cable 242 is tensioned, pulling the second opening and closing door 24, which is in the closed state. Conversely, when the hopper is tilted, the piston rod of the hydraulic cylinders 241 extends, the second opening and closing door 24 rotates and opens, and the first opening and closing door 23 opens naturally, allowing the second cavity 22 to unload. A conduit 243 is provided inside the second cavity 23, and the connecting cable 242 passes through the conduit 243 and connects to the second opening and closing door 24 to reduce the contact between the connecting cable 242 and the grain.

[0041] like Figure 9-10As shown, the rainproof assembly 4 is located on the upper part of the hopper 2. The rainproof assembly 4 adopts a structure similar to a roller shutter, including: a retractable rain cloth 41 and a track 42. Several connecting plates 43 are provided on both sides of the retractable rain cloth 41. The track 42 is located on the top of the hopper 2. Several connecting plates 43 are connected to form a chain-like structure. The adjacent connecting plates 43 are connected by a hinge pin and hole matching structure as disclosed in CN215908321U. That is, the hinge pin has a pivot part and a stop part, and the hole has a pivot hole part and a stop hole part that respectively match the pivot part and the stop part, so that it can only bend in one direction. This avoids the problem that the connection point bends when the motor unwinds due to the conventional connection method of two-way bending, which prevents the retractable rain cloth 41 from being effectively unwound. The end of the track 42 extends to the roller outlet of the rainproof assembly 4, maximizing the length of the constrained area of ​​the connecting plate 43, so that the packaging can be unwound normally. It should be noted that the retractable tarpaulin 41 can also be retracted and unloaded using a roller shutter structure + linear guide pair. That is, the top two sides of the hopper 2 are linear guide pairs, and the end of the retractable tarpaulin 41 is fixed to the linear guide pairs. When unwinding, the retractable tarpaulin 41 is dragged by the linear guide pairs. When rewinding, the linear guide pairs and the motor work together, and the two run at the same speed to keep the tarpaulin 41 taut and retract it onto the roller.

[0042] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
