Abstract

A tilling and harrowing boat with a traveling wheel in the middle, which comprises a guide disc, a boat body, a traveling wheel and a rotary tillage roll. A seat is fixed in the front of the boat body, a fast and slow shift operation rod, a tilling and harrowing shift operation rod and a clutch operation rod are arranged beside the seat, a diesel engine is fixed in the middle of the boat body, a gear box is fixed onto the back portion of the boat body, a mud guard is fixed onto the tail portion of the boat body, the gear box is fixed in the middle of the rear end of the boat body, two ends of an output shaft of the gear box are square shafts, the rotary tillage roll is arranged on the square shafts, and the traveling wheel is disposed at a position near the gear box on an output shaft on one side of the gear box. The utility model designs the gear box and the traveling wheel near the central axis at the back portion of the boat body, leads the gear box and the traveling wheel to coaxially move at different speeds, and greatly simplifies design of the gear box. When traveling, the motive power is in the middle of the boat body, the traveling wheel is in the middle and drives rollers at two ends to work, thereby radically overcoming the defects that the existing tilling and harrowing boat are operated with great efforts, can not till and harrow ridge edges, and has multiple faults.

Description

The cattail cultivating boat of a kind of road wheel in the middle of hull

[technical field]

The utility model relates to agricultural machinery, the cattail cultivating boat of promptly a kind of road wheel in the middle of hull.

[background technology]

Develop rapidly along with agricultural machinery, grain header universal day by day, the hardness of field piece is more and more higher, machine Pu ship in the past is not competent far away, particularly hills area and mountain area, main equipment is subjected to the restriction of geographical conditions, and a kind of collection of active demand ploughed Pu, both can do with the harvested field of grain header piece; The field piece that can adapt to the dark mud pin in hills and mountain area again; Should be in light weight, volume is little; Durable in use again, should flexible operation simple; The safe and reliable machine Pu ship of performance again.In recent years, there was a lot of agricultural machinery producers to do a lot of effort, and produced several cattail cultivating boat tests and used, but effect was not good always, studies carefully its defective following points:

1, road wheel design is rolled when working with road wheel when Pu on the right, and promptly a bull wheel and a steamboat move simultaneously, and steamboat is longer, power again at one end can produce seriously monolaterally, and it is gruelling to operate, labour intensity is big, and cultivated Pu all can not go up balk, and the peasant uses very inconvenient.

2, the gearbox design is too cumbersome, maintenance difficult.

3, because gearbox designs on one side, the power of rotary tillage Pu roller is imported at one end, and roller is longer, and the neither one datum level be difficult to guarantee its axiality, so fault is more again.

[summary of the invention]

Require great effort, can not plough limit, Pu field and the many shortcomings of fault for the reduction box and the road wheel that overcome present cattail cultivating boat in the operation of hull one side, the utility model proposes a kind of new design the cattail cultivating boat of road wheel design in the middle of hull.

The cattail cultivating boat of this road wheel in the middle of hull, comprise positioning disk, hull, road wheel and rotary tillage are rolled, positioning disk is installed in the hull front end by connecting rod and girder, the connecting rod upper end is fixed with steering wheel, fore-body is fixed with the seat, the other speed shelves action bars that is fixed with in seat, plough Pu shelves action bars and clutch lever, midship is fixed with diesel engine, afterbody is fixed with gearbox, there is belt to link to each other between the output belt pulley of diesel engine and the input belt pulley of gearbox, be fixed with fender at the hull afterbody, it is characterized in that gearbox is fixed on the middle part of hull rear end, the output shaft two ends of gearbox are square shaft, rotary tillage is housed on the square shaft rolls, on the output shaft of gearbox one side, road wheel is housed near the gearbox place.

Gearbox comprises housing and 5 parallel power transmission shafts, axle 1 is a power shaft, axle head is equipped with input belt pulley and clutch, be fixed with gear 6 and gear 7 on the axle 1, on the axle 2 gear 8 be housed, 9,10, gear 8,9 are connected as a single entity, can on axle 2, slide, with gear 6 or gear 7 engagements, on the axle 3 gear 11 is housed, gear 11 and gear 10 engagements, on the axle 4 gear 12 is housed, 13,14,15,

gear

13,14 are connected as a single entity, and can slide on axle 4, with gear 17 or gear 18 engagements, on the axle 5 gear 16 is housed, 17,18,19, gear 16 and gear 12 engagements, gear 19 and gear 15 engagements, stretch out outside the gearbox at axle 5 two ends, for Pu is rolled output shaft, be connected with the road wheel output shaft with screw on gear 19, the road wheel output shaft is a cylindrical shape, is enclosed within on the axle 5, be fixed with road wheel on the road wheel output shaft, on gear 8 and gear 14 shift fork is housed, the shift fork on the gear 8 links to each other with speed shelves action bars, and the shift fork on the gear 14 links to each other with cultivated Pu shelves action bars.

During work, start diesel engine, to the belt pulley on the gear-box axle 1, pass through clutch lever by belt transmission, the interlock clutch, drive axle 1 and rotate, when gear 6 and gear 8 engagements, work to fast, when gear 7 and gear 9 engagements, work is at a slow speed, and gear 10 is driven gear 11 successively, 12,16 rotate, and make Pu roll work, when gear 17 and gear 13 engagements, gear 15 driven gears 19, road wheel output shaft and road wheel rotate, and this moment, walking was very fast, was Pu field state, when gear 18 and gear 14 engagements, gear 15 driven gears 19, road wheel output shaft and road wheel rotate, and this moment, walking was slower, was the cultivated land state.

The utility model designs gearbox and road wheel near the afterbody axis, make the motion of rotary tillage wheel and the coaxial and different speed of walking crop rotation, simplified the design of gearbox greatly, during walking, power is at midship, road wheel is in the centre, and the Pu that drives two ends is rolled work, has fundamentally solved present cattail cultivating boat operation effort, can not plough Pu balk and the many shortcomings of fault.
