Abstract

The utility model provides a propeller-type tiller, which is a machine for tilling in agriculture. The utility model discloses a propeller-type tiller in order to enhance the work efficiency with a large range. The utility model comprises a boat-shaped body 9, a prime mover 8, a speed changing box 6, four collapsible wheels 7, the driving mechanism of the collapsible wheels 7, a seat 10, a circular blade rudder 12, the control mechanism 11 of the circular blade rudder 12, a mud guard 4, and a pulling device, wherein, the pulling device is composed of an adjustable shelf 3, a plough, and a harrow 2. The utility model is characterized in that the back end surface of the boat-shaped hull is provided with a propeller 5 which can be used as a machine for breaking earth and a pusher. The utility model is mainly used for the operation in paddy fields, and the utility model is suitable for the operation in upland fields after the utility model is refitted.

Description

The propeller type tiller

The utility model relates to a kind of agricultural tillage machinery.

Plough and still generally use ox to draw wooden ploughs in the rural area at present, for a change this backward state, and the sixties were once advocated the tillage implement reform, but made little progress.Heavy tractor is absorbed in the paddy field and can not extricate oneself, and is not used further to cultivated land substantially.In recent years Pu occurred and rolled the tillage machinery of ship, harvesting and tillage machine one class, wherein the harvesting and tillage machine of producing with Leiyang City, Hunan Province rice transplanter factory is comparatively practical, but this machinery can only be ploughed about five mu day, and work efficiency is still undesirable.

The purpose of this utility model is the weak point that overcomes in the above-mentioned background technology, and a kind of tiller of propeller type efficiently is provided, and this machine mainly is applicable to paddy-field-working, also can be used for dryland operation after being reequiped.

The purpose of this utility model realizes by taking following proposal:

1, adopts ship shape fuselage 9, prime mover 8,6, four wheels 7 of gearbox and transmission mechanism thereof, seat 10, rudder 12 and operating mechanism 11 and draw-gear;

2, establish two at ship shape back body face and have contour axle and the measure-alike screw 5 parallel with direct of travel, each screw has several uniform helical blades, and there is cutting edge the front side of each helical blade; From the stern eyes front, left-hand airscrew is for turning clockwise, and its blade is a right-hand screw, the right-hand screw oar turn to and the blade rotation direction all in contrast;

3, in ship shape back body both sides, i.e. the open dashboard 4 in all oriented back, the both sides of two screws;

4, draw-gear is made of the adjustable shelf 3 that is hinged on ship shape back body both sides and this harrow-like implement for pulverizing soil and rake that upward can rotate, harrow-like implement for pulverizing soil and rake are on the axle adorns a plurality of circular knifes, the external diameter of rake and circular knife spacing all are twices of harrow-like implement for pulverizing soil, the external diameter and the helical blade equal in length of rake, without draw-gear the time, it upwards can be rotated, be recovered on the ship shape fuselage;

5, rudder is a circular knife;

6, wheel is collapsible, and its support upper end is hinged on the sidewall of ship shape fuselage, and the time spent can upwards not dig.

The utility model is compared background technology and is had the beneficial effect that can increase substantially farming efficient, because the structure of helical blade had both helped stirring and broken soil, can this tiller be pushed forward fast by the reaction force of soil again, be that screw is a soil breaking tool, be again propeller, so can improve farming efficient significantly.

Description of drawings: Fig. 1, propeller type tiller front view; Fig. 2, propeller type tiller vertical view.

The utility model is done further narration below in conjunction with the accompanying drawing illustrated embodiment:

The ship shape fuselage is made with light material, and complete machine weight adds that driver's body weight is as the criterion can float over the mud face, and the width of fuselage is advisable so that two screws can laterally be installed, and fuselage length is the twice of width.It is to be convenient to travel on the road of field that collapsible wheel is installed.Farming drought soil can be without the ship shape fuselage, and gets final product with the framework of being with wheel.

Helical blade length is about four cuns with reference to the arable land degree of depth, and the number of blade is with reference to the thickness of cutting earth, and blade requires to be convenient to loading and unloading.

Field soil between two screws has the band of balking, and when having ploughed the Tian Tuhou of delegation and go back to, can handle this machine and laterally move suitable distance, can absolutely plough whole fields soil, owing to this motor speed is fast, so that such work still can keep is efficient.

Claims

1, propeller type tiller, comprise ship shape fuselage (9), prime mover (8), gearbox (6), four wheels (7) and transmission mechanism thereof, seat (10), rudder (12) and operating mechanism (11) and draw-gear is characterized in that: at ship shape back body face, have two to have contour axle and the measure-alike screw (5) parallel with direct of travel, each screw has several uniform helical blades, and there is cutting edge the front side of each helical blade; From the stern eyes front, left-hand airscrew is for turning clockwise, and its blade is a right-hand screw, the right-hand screw oar turn to the blade rotation direction all in contrast;

2, propeller type tiller according to claim 1 is characterized in that: all oriented back open dashboard (4) in ship shape back body both sides;

3, propeller type tiller according to claim 2, it is characterized in that: described draw-gear is by the adjustable shelf that is hinged on ship shape back body both sides (3) and this goes up rotary harrow-like implement for pulverizing soil (1) and rake (2) constitutes, harrow-like implement for pulverizing soil and rake are on the axle adorns a plurality of circular knifes, the twice that the external diameter of rake and circular knife spacing are harrow-like implement for pulverizing soil, the external diameter of rake equals helical blade length;

4, propeller type tiller according to claim 3 is characterized in that described rudder is a circular knife;

5, propeller type tiller according to claim 4 is characterized in that described wheel is collapsible, and its support is hinged on the sidewall of ship shape fuselage.
