Arrangement structure for handgrip seat, rear wheel assembly and transmission case of portable micro ploughing machine

Abstract

The invention discloses an arrangement structure for a handgrip seat, a rear wheel assembly and a transmission case of a portable micro ploughing machine. The bottom of a front support (19) is connected with the top of the front end of a screw rod transmission case (18), rear wheels (15) are symmetrically arranged on the left side and the right side under the rear part of a horizontal tube (7) and are rotationally sheathed with the end part of a wheel axle (16), and left and right strip blocks (17) are symmetrically arranged on the wheel axle (16) and are connected with a first rear wheel mounting hole (6a) in an inclined tube (6) or a second rear wheel mounting hole (5e) in a bent tube (5) through bolts, and the inclined tube (6) and the bent tube (5) are arranged on the corresponding side. The handgrip seat and a handgrip tube, for forming a handgrip, are in a split-type structure and can be convenient to detach and mount; the rear wheels can be retracted or laid down simply and quickly as required, so that the working efficiency of the micro ploughing machine can be effectively improved. The screw rod transmission case is horizontally mounted, so that the volume of the micro ploughing machine can be further decreased, and the screw rod transmission case is firm and reliable to mount and has good smoothness.

Description

technical field [0001] The invention belongs to the technical field of tillage machines, and in particular relates to the arrangement structure of a handle seat, a rear wheel assembly and a transmission box on a tillage machine. 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 ...

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

[0006] 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
