Problems solved by technology

[0004] First: The ring gear used is an inner ring gear, so the gears on the output shaft of the gearbox must be arranged inside the ring gear, that is, the internal meshing method is used to realize the drive, which not only occupies the internal diameter size, but also the rotating gear and the ring gear are easy Contact with bark, causing broken bark
The tree mover can only dig soil for trees with a smaller diameter, and the tree mover is limited for digging trees with a larger diameter
[0005] Second: using a hydraulic motor, the drive train needs to be transformed through the arrangement of the gearbox, which increases the weight of the mechanism and also occupies the internal diameter

Embodiment 1

[0048] The dual hydraulic motor tree moving machine driving system of the present invention drives gear one 70 and gear two 80 to rotate through the first hydraulic motor 7 and the second hydraulic motor 8 at the same time, drives the outer ring gear 21 with the slewing ring 2 on the roller bearing 41 Under the support, rotate clockwise or counterclockwise 360° in the annular groove 10 in the slewing support upper cover 1. In the present invention, an outer ring gear 21 is arranged on the outer ring of the slewing ring 2, which avoids double gears occupying the inside of the slewing support upper cover 1. The diameter size increases the diameter of the tree moved by the tree mover.

Embodiment 2

[0050] The drive system of the tree moving machine with dual hydraulic motors of the present invention avoids the contact between the double gears and the bark, causing broken bark, and improves the integrity of the tree after excavation.

Embodiment 3

[0052] In the hydraulic system in the dual hydraulic motor tree moving machine drive system of the present invention, the hydraulic pump 93 extracts the hydraulic oil from the oil tank 90 and passes through the filter 91 to filter and the shut-off valve 92 reaches the one-way valve 94 from the oil outlet of the hydraulic pump 93 and Relief valve 96, when the left position of the reversing valve 95 is connected, the hydraulic oil enters the first hydraulic motor 7 and the second hydraulic motor 7 from the oil outlet port of the check valve 94 through the P port and B port of the reversing valve 95. The oil outlet of the motor 8 enters, drives the first hydraulic motor 7 and the second hydraulic motor 8 to rotate forward, and then the hydraulic oil flows out from the oil inlet of the first hydraulic motor 7 and the second hydraulic motor 8, and then flows through the reversing valve 95 The A port and T port of the reversing valve 95 enter the oil tank 90; when the right position ...

Abstract

The invention discloses a double-hydraulic-motor tree transplanting machine driving system. The double-hydraulic-motor tree transplanting machine driving system comprises a rotary supporting upper cover, a rotary ring, a lifting lug, a riding wheel assembly, a top wheel assembly, a gear box body, a first hydraulic motor, a second hydraulic motor and a hydraulic oil way system. First annular grooves are arranged in the rotary supporting upper cover, the rotary ring is rotationally connected with the first annular grooves, the two side walls of the rotary ring are provided with second annular grooves, the lifting lugs are connected with the upper end of the rotary supporting upper cover, the riding wheel assemblies are embedded into the second annular grooves, the top wheel assemblies are jacked into the second annular grooves, the number of the gear box bodies is two, the first hydraulic motor is connected with the gear box body on one side, and the second hydraulic motor is connected with the gear box body on the other side. The hydraulic oil way system is connected with the first hydraulic motor and the second hydraulic motor through oil ways, double hydraulic motors simultaneously drive double gears to be meshed with an outer gear ring for driving, the double gears occupy the internal diameter size is avoided, and the diameter of a tree operated by the tree transplanting machine is increased; and the double gears are prevented from making contact with barks to cause bark breakage, and the completeness of the excavated trees is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry machinery, in particular, the invention relates to a driving system of a tree moving machine with double hydraulic motors. Background technique [0002] In the process of garden nursery operations and garden engineering construction operations, it is often necessary to transplant live trees. The traditional operation method is to manually draw a circle around the root of the big tree, with the base of the trunk as the center, and extend a certain percentage of radius outwards to draw a circle at a fixed point. The big tree is moved away from the original growth site together with the excavated soil ball. [0003] The research and development of mechanical products for tree-digging operations, especially the research and development of mechanical operation attachments for digging soil balls, is one of the key technologies for developing tree-moving machinery. The patent number i...
