AI Technical Summary

Technical Problem

During the adjustment process, the grooves and fixing holes for installing extension rods in the existing mini-tiller towing structure are prone to accumulating soil, affecting the stability and applicability of the position adjustment.

Method used

A drag-and-drop structure was designed, comprising a mounting frame, mounting base, clamping block, spring telescopic rod, threaded rod, and sealing plate. The extension rod is stably adjusted through the cooperation of the threaded ring and threaded rod. The sealing plate and suction cup ensure the sealing of the groove, and the spring telescopic rod provides cushioning to adapt to different soil hardness.

Benefits of technology

It achieves stable adjustment of the extension rod position, avoids mud accumulation in the grooves and holes, improves the applicability and working effect of the towing structure, and ensures stable operation of the mini tiller under different soil conditions.

Abstract

The utility model belongs to the technical field of agricultural planting, and particularly relates to a mini-tiller dragging structure which comprises an installation frame, an installation base and a clamping block, the clamping block is installed on an extension rod, the extension rod is installed on the installation frame in a sliding mode, a plurality of fixing grooves are formed in the side wall of the extension rod, and the clamping block is installed on the installation base. A fixing groove is formed in the mounting rack, a sealing plate is mounted on the fixing groove through a spring, a fixing plate matched with the fixing groove is mounted on the side wall of a groove, where the fixing plate is mounted, of the mounting rack through a spring, the top surface of the fixing plate is an inclined surface, and a top frame matched with the fixing plate is mounted on the mounting rack through a screw rod; by arranging the fixing plate located on the side wall of the groove where the extension rod is installed and the fixing groove where the sealing plate is installed through the spring, it is guaranteed that the hole where the extension rod is fixed and the groove where the extension rod is installed are not exposed to the outside, and a user can conveniently adjust the position of the extension rod; and the stability of the sealing plate in the using process of the device is improved.
