Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a harvesting vehicle suitable for confined spaces. Background Technology

[0002] In crop harvesting operations, manual handling is the main method. Existing mechanical harvesting vehicles are too large, making them difficult to maneuver and restricting their movement. This makes them unsuitable for harvesting operations in confined spaces such as greenhouses, leading to increased labor costs and low crop transportation efficiency. Not only does this consume a lot of time, but it also seriously affects transportation efficiency, resulting in the inability to transfer harvested crops in a timely manner and increasing the risk of loss.

[0003] Therefore, how to design a harvesting vehicle that is highly efficient in transporting crops and suitable for confined spaces is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This invention provides a harvesting vehicle suitable for confined spaces, solving the technical problems of existing crop harvesting vehicles being difficult to turn, having limited movement, and being unable to adapt to confined spaces.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a harvesting vehicle suitable for confined spaces, comprising: a transport box and multiple steering drive wheels.

[0006] Multiple steering drive wheels are fixed at intervals to the bottom of the transport box, and each steering drive wheel includes a shock-absorbing assembly, a wheel frame, a wheel, a travel motor, and a steering motor. Multiple shock-absorbing assemblies are fixed at intervals to the bottom of the transport box and have inherent passive steering gears mounted on them. The top ends of multiple wheel frames are respectively fixed to the bottom ends of multiple shock-absorbing assemblies. Multiple wheels are rotatably connected to multiple wheel frames. Multiple travel motors are respectively fixed to multiple wheel frames, and their output shafts are respectively connected to multiple wheels via pulleys, belts, sprockets, chains, or gears. Multiple steering motors are fixed to multiple wheel frames, and their output shafts have inherent active steering gears mounted on them. Multiple active steering gears are respectively meshed with multiple passive steering gears to drive the corresponding wheels to rotate in the same direction as the output shafts of the multiple steering motors rotate.

[0007] The beneficial effects of this utility model are: it improves the structure of traditional crop harvesting vehicles by first fixing multiple steering drive wheels at intervals at the bottom of the transport box, and then using the walking motor and steering motor to drive the wheels to rotate and turn respectively, which can turn flexibly (360-degree turn on the spot) and adapt to crop transportation in small areas such as greenhouses.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes a front telescopic transport assembly, a front pull rope, a rear telescopic transport assembly, and a rear pull rope. The front and rear ends of the transport box in the direction of movement are respectively provided with a forward entry hole and a rear entry hole. One end of the front telescopic transport assembly is hinged to the forward entry hole at the front end of the transport box in the direction of movement. One end of the front pull rope is fixed to the front end of the transport box in the direction of movement, and the other end is fixed to the front telescopic transport assembly. One end of the rear telescopic transport assembly is hinged to the rear entry hole at the rear end of the transport box in the direction of movement. One end of the rear pull rope is fixed to the rear end of the transport box in the direction of movement, and the other end is fixed to the rear telescopic transport assembly.

[0010] The further beneficial effect of adopting the above is that by using the front pull rope and the rear pull rope to connect the front telescopic transport assembly and the rear telescopic transport assembly respectively, since the front telescopic transport assembly and the rear transport assembly are respectively arranged on the front port and the rear port of the transport box, the harvested crops can be collected and the harvested crops can be collected quickly.

[0011] Furthermore, it also includes multiple reinforcing rods, which are fixed in pairs to the outer side of the transport box.

[0012] The further beneficial effect of adopting the above is that by using a set of two reinforcing rods crosswise and fixed to the outer side of the transport box, the structural strength of the transport box can be enhanced, and damage to the transport box structure can be avoided by increasing the amount of crops loaded.

[0013] Furthermore, all of the aforementioned reinforcing rods are galvanized steel pipes.

[0014] Furthermore, it also includes an unloading door, and the side of the transport box is provided with an unloading hole; the unloading door is hinged at the unloading hole.

[0015] The further beneficial effect of adopting the above is that by connecting the unloading door to the unloading hole, when the unloading door is opened, the crops in the transport box can flow out by their own weight, quickly completing the unloading or transfer.

[0016] Furthermore, it also includes a controller and a battery, the battery being fixed to the transport box; the controller is communicatively connected to the battery, the travel motor and the steering motor via wired or wireless means respectively. Attached Figure Description
