Description

Technical Field

[0001] The invention belongs to the technical field of seedling pruning machines, and in particular relates to a seedling pruning machine with adjustable wheel spacing for forest cultivation and a use method thereof. Background Art

[0002] The seedling pruning machine helps farmers and gardeners to complete the pruning of trees and seedlings quickly and efficiently through mechanized means. It not only improves pruning efficiency, but also maintains pruning consistency, reducing the labor intensity and injury risk of workers.

[0003] The authorization publication number "CN116849046B" records "a seedling pruning machine with adjustable wheelbase, comprising a pruning machine body, an extension rod extending outward from the body, a movable auxiliary wheel being arranged on the extension rod, a mounting rod being arranged on the body, a blade device being arranged on the mounting rod, a movable sliding member being arranged perpendicular to the mounting rod, a connecting member being arranged on the extension rod, a support rod being arranged between the connecting member and the sliding member, one end of the support rod being connected to the sliding member through a turntable, and the other end being rotatably arranged on the connecting member, when the auxiliary wheel moves away from the body, the connecting member moves synchronously, and under the action of the support rod, the auxiliary wheel becomes parallel to the body. It is achieved that the greater the movement speed of the body, the greater the supporting force of the support rod on the extension rod, and vice versa, the smaller the supporting force of the support rod on the extension rod, and the movement speed of the body is adapted in real time to prevent pruning differences caused by the lag of the auxiliary wheel and to prevent the breakage time of the extension rod from being slowed down, thereby increasing the service life of the extension rod."

[0004] The above patent can increase the service life of the extension rod, but it is not easy to prune seedlings of different heights and the sides of seedlings, and it is not convenient for storage and transportation. When pruning seedlings, some of the pruned branches will fall to the front of the moving wheel. If they are not cleaned in time, it will be inconvenient to move the trimmer, which will ultimately lead to low pruning efficiency. Summary of the invention

10. A method for using a seedling pruning machine with adjustable wheelbase for forest cultivation, characterized in that: The method is applied to a forest cultivation sapling pruning machine with adjustable wheelbase as claimed in any one of claims 1 to 9, comprising the following steps: S1. Adjusting the height and wheelbase: adjusting the position of the trimmer body (3) according to the height of the plant to be trimmed, turning on the fixed motor (201) and the adjusting motor (412) at the same time, driving the fixed gear (202) to rotate by the fixed motor (201), driving the fixed threaded rod (204) to rotate by the transmission of the toothed belt, so that the movable plate (205) pushes the trimmer body (3) to move, driving the adjusting gear (413) to rotate by the adjustment motor (412), driving the mounting threaded rod (409) to rotate by the transmission of the toothed belt, so that the support plate (408) pushes the connecting plate (402), the electric telescopic rod (401) and the trimmer body (3) to move, and when the trimmer body (3) moves to a suitable height, stopping the rotation of the fixed motor (201) and the adjusting motor (412), and adjusting the position of the movable wheel (414) can be adjusted by the push of the electric telescopic rod (401), thereby adjusting the wheelbase; S2. Side trimming and storage: When the side needs to be trimmed, the adjustment motor (412) and the installation motor (404) are turned on at the same time, and the position of the moving wheel (414) is adjusted by the adjustment motor (412). The installation gear (405) is rotated by the rotation of the installation motor (404). The installation gear (405) and the connecting gear (406) are meshed, so that the connecting rod (407) drives the fixing plate (403) and the support plate (408) to flip, thereby causing the support plate (408) to rotate. The moving wheel (414) is turned over to the top of the trimmer body (3), and then the rotating motor (206) is turned on. The angle of the trimmer body (3) is adjusted by the rotating motor (206) so that the trimmer body (3) and the mobile cart (1) are perpendicular to each other, so that the sides of the seedlings can be trimmed. At the same time, during the transportation process, the adjusting mechanism (4) and the trimmer body (3) can be stored by the cooperation of the moving mechanism (2), the trimmer body (3) and the adjusting mechanism (4), thereby reducing the volume of the mobile cart (1); S3, clearing obstacles: When the mobile cart (1) and the trimmer body (3) cooperate to trim the seedlings, the swing motor (501) is turned on, and one of the synchronous wheels (502) is driven to rotate by the swing motor (501). The fixed rod (503) can drive the fixed bevel gear (504) to rotate through the transmission of the synchronous belt. By meshing the installed bevel gear (505) and the fixed bevel gear (504), the swing rod (506) can drive the fixed claw (507) to swing, so as to clear the broken branches in front of the mobile cart (1).
