Description

TECHNICAL FIELD

[0001] The present application relates to an adjustable slope vibration harvesting operation vehicle, belonging to the technical field of fruit harvesting operation vehicle. BACKGROUND

[0002] The use of mechanical harvesting operation vehicles in orchards can greatly improve harvesting efficiency, but is affected by factors such as terrain undulations, which to some extent restricts the use and promotion of harvesting operation vehicles. In order to adapt to the changes in the terrain of the orchard with undulating height, CN112088654A discloses a fruit harvesting operation vehicle, wherein a jacking assembly for changing the inclination angle of the belt fruit collecting mechanism is installed on the crawler walking mechanism, and the belt fruit collecting mechanism is hinged to the jacking assembly, so that the fruit collecting mechanism can automatically adjust the undulation with the change in ground height, prevent the chassis from being inserted into the soil, meet the harvesting needs of orchards in mountainous and hilly areas with pits and uneven terrain, and improve the terrain adaptability and practicality of the whole machine. CN111011002A discloses a forest fruit harvesting operation vehicle, wherein the U-shaped positioning chassis moves through the driving of the centering assembly, and can be telescopic, up and down, and left and right swinging. When the walking mechanism cannot approach the trunk closely, the centering assembly is moved to effectively position the loading mechanism on the trunk, extending the movement range of the loading mechanism, reducing the walking demand of the walking mechanism on the terrain, ensuring that the loading mechanism can be effectively positioned on the trunk according to the position, thickness and height of the trunk, and meeting the vibration and collection needs of orchards in mountainous and hilly areas with pits and uneven terrain.

[0003] The first kind of harvesting operation vehicle described above adjusts the undulation of the fruit collecting mechanism with the movement of the jacking assembly to adapt to the terrain. The jacking mechanism is controlled by an oil cylinder, and during the walking process of the harvesting operation vehicle, the oil cylinder needs to be controlled manually to make the fruit collecting mechanism rise and fall, while the second kind of harvesting operation vehicle adjusts the position of the U-shaped positioning chassis to meet the vibration and collection needs of the fruit in uneven terrain. However, camellia oleifera trees have low requirements for terrain and can be planted in many scenarios, not only in orchard land with undulating height, but also on sloping land with a certain slope. However, when the harvesting operation vehicle works on a large slope, the power is not continuous due to the inclination of the diesel engine, and the height difference between the front and rear ends of the fruit collecting mechanism is too large, which can cause the fruit to roll out and run off during the output process, resulting in low fruit collection efficiency. How to make the harvesting operation vehicle adapt to the slope harvesting operation and improve the harvesting efficiency and reliability is the purpose of the present application. SUMMARY

[0004] The adjusting type slope land vibration harvesting operation vehicle provided by the application can adapt to the working condition requirement of the engine when the vehicle works on a large slope land, improve the reliability and stability of the power output of the harvesting operation vehicle, reduce the probability of fruit running in the process of fruit collection, improve the fruit collection efficiency, improve the harvesting rate, make the harvesting operation vehicle adapt to the harvesting operation on the slope land, and improve the harvesting efficiency and reliability.

[0038] The power mechanism 4 comprises a hydraulic system, an engine 6 connected with the hydraulic system, a sub-gearbox 7 connected with the output end of the engine 6, and a main gearbox 8 connected with the sub-gearbox 7 through a clutch 70. The engine 6 is connected with the frame 1 through an angle adjusting assembly 9, which obtains power from the hydraulic system and is controlled by the operation platform 5 to drive the engine 6 to swing and adjust the inclination angle.

[0039] The fruit collecting mechanism 3 is supported above the main gearbox 8 through an adjusting support assembly 10, which obtains power from the hydraulic system and is controlled by the operation platform 5 to drive the fruit collecting mechanism 3 to swing and adjust the inclination angle.

[0040] In the above-mentioned adjustable slope vibration picking operation vehicle, the engine 6 is connected with the frame 1 through the angle adjusting assembly 9, which drives the engine 6 to swing and adjust the inclination angle. During slope operation, the inclination angle of the engine 6 is reduced to avoid the lack of internal lubricating oil of the engine, which may cause poor internal lubrication or damage during slope operation. The engine working condition can be adapted to the slope operation of the picking operation vehicle, and the reliability and stability of the power output of the picking operation vehicle are improved. The fruit collecting mechanism is supported above the main gearbox through the adjusting support assembly 10, which adjusts the inclination angle of the fruit collecting mechanism 3 to reduce the probability of fruit running during the output of the fruit collecting mechanism 3 during slope operation, improve the fruit collecting efficiency, and improve the picking rate.

The engine lifting oil cylinder 92 pushes the engine fixing frame 91 to swing upward, reduces the downward inclination angle of the engine during the slope operation, avoids the downward inclination of the engine oil tank to affect the oil supply efficiency and make the power output discontinuous, and ensures that the harvesting vehicle can adapt to the working condition requirements of the engine during the operation on a larger slope.

Since the output shaft of the engine 6 will form an angle change with the adjustment of the inclination angle of the engine 6, in order to ensure that the engine 6 can be connected with the input shaft of the auxiliary gearbox 7 to realize power transmission at any angle, the output ball head sleeve 61 is arranged at the output end of the engine, the input ball head 71 is arranged at the input shaft of the auxiliary gearbox, the output ball head sleeve 61 is sleeved on the input ball head 71 in a spherical matching mode, the two can relatively swing in an axial direction to form an included angle, the semispherical protrusions 72 are matched with the semispherical grooves 62 to ensure that the output ball head 61 drives the input ball head 71 to rotate circumferentially, and the engine output shaft and the auxiliary gearbox input shaft form an included angle to ensure normal torque transmission, the adjustment of the inclination angle of the engine will not affect the transmission of the harvesting vehicle, and the transmission reliability of the harvesting vehicle is improved.
