Arrangement structure of rear wheel assembly and transmission box of a portable tiller

Abstract

The invention discloses an arrangement structure of a rear wheel assembly and a transmission box of a portable micro tillage machine. A beam (2) is fixed to the upper end of a front bracket (16), and the left and right ends of the bottom of the front bracket (16) are driven by bolts and screws. The top of the front end of the box (15) is connected, and the rear wheels (12) are symmetrically arranged on the left and right sides of the rear bottom of the horizontal tube (7). (13) is symmetrically provided with two left and right strips (14), and the strips (14) are connected to the first rear wheel mounting hole (6a) or elbow (5) on the corresponding side inclined pipe (6) by bolts. Connect to the second rear wheel mounting hole (5e) on the The rear wheel of the present invention can be stowed or put down according to needs, and the retractable operation is simple and fast, which can effectively improve the working efficiency of the tiller; the screw transmission box is installed horizontally, which can further reduce the volume of the tiller, and the screw transmission box The installation is firm, reliable and stable.

Description

technical field [0001] The invention belongs to the technical field of tillage machines, and in particular relates to the arrangement structure of the rear wheel assembly and transmission box on the tiller Background technique [0002] Micro tillage machine is an agricultural tool in the new era. It has the characteristics of light weight, small size and simple structure. It is widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. , spraying and other operations, it can also be towed by a trailer for short-distance transportation. The micro tillage machine has strong flexibility, can drive freely in the field, is convenient for users to use and store, saves the trouble of large agricultural machinery not being able to enter the mountainous fields, and saves farmers a lot of time in the busy season. [0003] The frame is an important part of the tiller, and it is the skeleton of the tiller, which is used to arrange the powertrain, blade, hand...

AI Technical Summary

Problems solved by technology

The above structure is not only cumbersome to disassemble and assemble, the labor intensity of the staff is high, and it will greatly reduce the working efficiency of the tiller

[0005] The powertrain on the tiller is usually a vertical engine, and the screw transmission box is installed vertically accordingly. On the one hand, the installation process of the worm transmission box is relatively complicated and the reliability is poor; on the other hand, the worm transmission box is installed in the The rack takes up a lot of space, which will also increase the volume of the whole tiller
