Description

Technical Field

[0001] The utility model relates to the field of agricultural equipment, in particular to an all-terrain agricultural flatbed vehicle. Background Art

[0002] In the agricultural field, with the development of automation and intelligent technology, the innovation of agricultural transport vehicles has become an important means to improve agricultural production efficiency. Traditional agricultural transport vehicles usually use manual driving or simple remote control operation, which is difficult to operate flexibly in complex field environments. This operation method not only increases labor intensity, but also limits work efficiency to a certain extent. In recent years, with the advancement of artificial intelligence, sensing technology and positioning technology, intelligent follow-up transport vehicles have gradually entered the market and become an important research direction of agricultural mechanization.

[0003] However, the agricultural production environment usually has complex terrain features, such as mountains, hills, wetlands, muddy fields, etc. Traditional agricultural machinery and equipment have limited traffic capacity and operational flexibility on these complex terrains, which can easily lead to low production efficiency and even equipment damage. Most traditional agricultural flatbed trucks cannot adjust the height of each wheel according to the different driving surfaces, so that each wheel can fit with the ground during driving, which makes the agricultural flatbed truck less stable to use.

[0004] Therefore, those skilled in the art provide an all-terrain agricultural flatbed vehicle to solve the problems raised in the above background technology. Utility Model Content

At the same time, the rotation connection between the circular shaft and the fixed block also realizes the independent flipping of the tires on each side, so that the placement frames on both sides can swing separately. Regardless of the terrain, the four wheels can touch the ground at the same time, and there will be no situation where three tires touch the ground and one tire is suspended on a rugged route. In order to better prevent the displacement of one side of the tire due to long-term walking, a limiting device composed of a limiting steel ring and a steel sheet is installed on each side of the frame to limit the distance of the tire movement, thereby well protecting the vehicle body.

[0033] Reference Figure 1-5 , an embodiment provided by the utility model:

[0034] An all-terrain agricultural flatbed vehicle comprises a load-bearing platform 1 and a placement frame 5. The front end of the upper surface of the load-bearing platform 1 is fixedly connected to a main base station 3, and the rear end of the upper surface of the load-bearing platform 1 is fixedly connected to a slave base station 4, so that the user can make the flatbed vehicle follow and move by holding a beacon. The periphery of the upper surface of the load-bearing platform 1 is fixedly connected to a guardrail 2. By setting the guardrail 2, the possibility of objects falling off is reduced. The rear end of the middle part of the inner bottom surface of the placement frame 5 is fixedly connected to a fixed block 7, and the inner wall of the fixed block 7 is rotatably connected to a cylindrical rod 8. The front end of the middle part of the inner bottom surface of the placement frame 5 is fixedly connected to a steel sheet 9. The middle part of the lower surface of the load-bearing platform 1 is fixedly connected to a vehicle frame 10. The front ends of the middle parts of the outer walls on both sides of the frame 10 are fixedly connected to a limiting steel ring 11, and the rear ends of the middle parts of the outer walls on both sides of the frame 10 are fixedly connected to a sleeve 12.

[0035] A driving mechanism 6 is provided on the inner top surface of the placement rack 5, and the driving mechanism 6 includes a placement shell 601 and a fixed shaft 608. The upper part of the outer wall at the rear end of the placement shell 601 is fixedly connected to a servo motor 602, the middle part of the inner walls on both sides of the placement shell 601 is rotatably connected to a driving rod 604, and the middle part of the outer wall of the fixed shaft 608 is fixedly connected to a tire 609.

[0036] Compared with most traditional agricultural flatbed trucks, this agricultural flatbed truck has a sleeve 12 installed in the middle of the frame 10. Through the unique sleeve 12 structure, the agricultural flatbed truck load platform 1 can be flipped up and down. At the same time, the rotation connection between the cylindrical rod 8 and the fixed block 7 also realizes the independent flipping of the tire 609 on each side, so that the placement frames 5 on both sides can swing separately. Regardless of the terrain, the four wheels can touch the ground at the same time, and there will be no situation where three tires 609 touch the ground while one tire 609 is suspended on a rugged route. In order to better prevent the displacement of one-side tire 609 due to long-term walking, a limiting device consisting of a limiting steel ring 11 and a steel sheet 9 is installed on both sides of the frame 10 to limit the movement distance of the tire 609, thereby well protecting the vehicle body.

[0037] The rear end of the inner bottom surface of the frame 10 is fixedly connected to a battery 13, and the battery 13 is provided to provide power to the flatbed vehicle. The front end of the inner bottom surface of the frame 10 is fixedly connected to a controller 14, and the outer wall of the front end of the controller 14 is fixedly connected to multiple data interfaces 15, so that the user can control the controller 14 or modify the data through the data interface 15. The output end of the servo motor 602 is fixedly connected to a worm 603, and the middle part of the outer wall of the driving rod 604 is fixedly connected to a gear 605. The worm 603 and the gear 605 are engaged, so that the servo motor 602 can rotate synchronously by controlling the first sprockets 606 on both sides, thereby To control the two tires 609 to rotate synchronously, the placement shell 601 is fixedly connected to the front end of the inner top surface of the placement frame 5, and the fixed shaft 608 is fixedly connected to the front end and the rear end of the inner wall of the placement frame 5, so that the driving mechanism 6 can be fixed to the frame 10 through the placement frame 5. Both sides of the outer wall of the driving rod 604 are fixedly connected to the first sprocket 606, and one side of the outer wall of the fixed shaft 608 is fixedly connected to the second sprocket 6010. The outer walls of the first sprocket 606 and the second sprocket 6010 are both sleeved with chains 607, so that the rotation of the first sprocket 606 can control the synchronous rotation of the second sprocket 6010, thereby controlling the rotation of the tire 609.

[0038] Working principle: First, place the items to be moved on the loading platform 1, and the user then carries a beacon, and places a main base station 3 and a slave base station 4 at the front and rear ends of the vehicle respectively. The controller 14 is equipped with UWB technology. Through the communication between the main and slave base stations on the vehicle and the beacons carried by people, the position of the beacon is calculated in real time, and then the walking path of the transport vehicle is controlled. This technology not only overcomes the defects of traditional visual recognition and GPS positioning, but also ensures stable and efficient execution of following tasks under various environmental conditions. When one of the wheels passes over an uneven ground, the tire 609 adheres to the ground under the action of gravity, and the placement frames 5 on both sides are rotatably connected by cylindrical rods 8, which enables the tires 609 on both sides to be flipped separately.
