Problems solved by technology

There are still some problems in the walking process of existing remote-controlled mobile robots: 1. Difficulty turning
Such a robot can move on circular arcs or straight lines with different curvature radii, and can also rotate in situ, but it cannot move along the normal direction of the wheel plane, and the steering angle is small, it is difficult to achieve omnidirectional steering, and the flexibility is poor, so it is not suitable The complex environment of agricultural production
2. Cannot realize height adjustment
The height of the vehicle body cannot be properly adjusted for crops of different heights, and the versatility is poor; the adaptability to terrain is not good, especially in hilly slopes, prone to rollover accidents

specific Embodiment approach 1

[0018] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the servo motor 9 is connected to the vehicle frame 8 with bolts, the pinion 7 and the power output shaft of the servo motor 9 are connected by a flat key, and the pinion 7 is axially fixed with a round nut. The pinion 7 meshes with the bull gear 6 . The steering sleeve 3 is fixedly connected with the bull gear 6 . Steering sleeve 3 lower end radiuses are little, have square hole inside its lower end, and this hole slides with hydraulic cylinder plunger 16 square shaft one ends. Steering sleeve 3 middle part is hollow, so that hydraulic lifting device 6 is installed inside. Have four grooves on the side of steering sleeve 3 circumferences, so that hydraulic pipes are installed. The lower surface circumference of the upper end of the steering sleeve 3 is provided with a semicircular groove 21 for installing balls 15, and the upper surface of the end cover 14 is also provided with a corresponding semici...

specific Embodiment approach 2

[0019] Such as figure 1 , figure 2 As shown, the vehicle electronic equipment includes: a battery pack 10 , a vehicle controller 11 , a remote control signal receiver 12 , and a wireless communication module 13 . The battery pack 10 is responsible for the power supply of the entire remote control platform; the whole machine controller 11, on the one hand, controls the movement of the mobile platform, that is, controls the start, stop and speed of the hub motor wheel 1, the rotation of the servo motor 9, the opening and closing of the solenoid valve and the hydraulic oil pump On the other hand, it realizes the exchange of signals, that is, realizes the reception and processing of input remote control signals and wireless signals, and can transmit them to remote computers and other mobile machine platforms through the wireless communication module 13 at the same time. If certain sensors and GPS are installed, it can also realize adaptive lifting and automatic navigation; the r...

Abstract

The invention relates to an omni-directional steering and lifting agricultural remote control mobile robot platform. The platform comprises an omni-directional steering mechanism, a hydraulic lifting system, a frame bench, vehicular electronic equipment and a traveling mechanism, the omni-directional steering mechanism is driven by a servo motor and transfers power to a steering sleeve through a pinion and a gearwheel, and then the power is transferred to wheel supports and hub motor-type wheels so that omni-directional steering is achieved, and the hydraulic lifting system is capable of lifting the platform under the action of hydraulic driving. The omni-directional steering and lifting agricultural remote control mobile robot platform has the advantages that by means of motor driving and hydraulic lifting which are performed independently, the platform can achieve 360-degree in-situ rotation while adjust the height of a vehicle body so as to adapt to crops of different heights and terrain environments; the platform is small in steering resisting moment during rotation and is easy and flexible to steer; and by the aid of the hub motor wheels, motors and the wheels are integrated, and the platform is structurally simplified.

Description

technical field [0001] The invention relates to an agricultural remote-control mobile robot platform, in particular to an agricultural remote-control mobile robot platform that can be turned up and down in all directions. Background technique [0002] At present, agricultural mechanization has received great attention from the state. Agricultural machinery for different crops such as wheat, corn, rice, and cotton has emerged one after another, but in teaching and experimental research, there is a lack of an agricultural mobile robot platform with a reasonable structure and easy walking. [0003] Agricultural remote control mobile robots can significantly improve the safety and comfort of operators in the agricultural production process, and greatly reduce people's labor intensity, especially in operations that endanger human health such as fertilization and spraying. The agricultural robot test and teaching A platform is very necessary. There are also some problems in the ...
