Abstract

A frame of a sowing fertilizer applicator comprises a main beam, a bracket connected at one side of the main beam, two hanging arms connected with the bracket, hanging holes arranged at the front of the hanging arm. The utility model has a simple sound structure. After combined with the sowing (fertilization) device to form the sowing fertilizer applicator, the utility model can be not only separately towed by a tractor, but also be towed by a tractor with the prior rotary tiller.

Description

The seeding and fertilizer spreading machine frame

Technical field

The utility model relates to the frame of agricultural machinery, specifically a kind of seeding and fertilizer spreading machine frame.

Background technology

The existing kind that is used for the agricultural machinery of farming has rotovator, sower, the fertilizer distributor of independent function, and the seeding and fertilizer spreading machine of tool sowing, fertilizing functions is also arranged, and also also having tool rotary tillage, sowing, fertilizing functions is combined agricultural machinery all over the body.At present, rotovator, sower, fertilizer distributor or seeding and fertilizer spreading machine use widely in the rural area.And be all over the body combined agricultural machinery as tool rotary tillage, sowing, fertilizing functions, though in operation, can plough simultaneously, sow, apply fertilizer, but its independent being used for to be ploughed, applied fertilizer or sowing, obviously unreasonable, and because its its structure is complicated, price is higher, therefore, present less use.In actual farming, need sometimes to make to plough to separate and carry out with sowing, fertilising, under the situation of condition permission, wish again sometimes to draw rotovator and sowing, fertilizer distributor simultaneously by a dilatory function, in the arable land, sow or apply fertilizer, to raise the efficiency.Existing rotovator and sower or fertilizer distributor are because self structure can't be drawn common operation simultaneously by a tractor.

The utility model content

The novel purpose of this use is to provide a kind of seeding and fertilizer spreading machine frame, this frame can with rotovator together by a tractor-drawn.

For achieving the above object, the utility model adopts following scheme: the seeding and fertilizer spreading machine frame, and it has a girder, is provided with the support that connects with it in a side of girder, is connected with two hitching arm on support, and the front end of hitching arm is provided with mount hole.Hitching arm can be articulated on the suspension arm at tractor rear portion by the mount hole of its front end.

On the suspension arm at tractor (four-wheel tractor or caterpillar tractor) rear portion, articulated under the state of rotovator, two hitching arm of above-mentioned seeding and fertilizer spreading machine frame still can be articulated in from the outside of rotovator on the suspension arm at tractor rear portion, like this, tractor can draw rotovator and this seeding and fertilizer spreading machine frame simultaneously.Sowing (fertilising) device is set on this seeding and fertilizer spreading machine frame, just can constitutes sowing (fertilising) machine.This shows, sowing (fertilising) machine that sowing (fertilising) device back constitutes is set on this seeding and fertilizer spreading machine frame, can with existing rotovator together by a tractor-drawn, carry out rotary tillage, operation is made up in sowing (fertilising).And, after the seeding and fertilizer spreading machine frame that is provided by the utility model combines with sowing (fertilising) device and constitutes sowing (fertilising) machine, can be by the independent towage of tractor.

The utility model is simple and reasonable for structure, after it form to sow (fertilising) machine with sowing (fertilising) device, both can be separately by tractor-drawn, again can with existing rotovator together by a tractor-drawn.

Description of drawings

The front view of Fig. 1 the utility model one embodiment;

The left view of Fig. 2 Fig. 1.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1

The seeding and fertilizer spreading machine frame that the utility model provides, it has a girder 1, is provided with the support 2 that connects with it in a side of girder 1, is connected with two hitching arm 3 on support 2.Be connected with two draw bars 10 on support 2 tops.

Referring to Fig. 2

Support 2 connects with girder 1 by " U " shape bolt 4 and nut 5.Hitching arm 3 connects with support 2 by " U " shape bolt 8 and nut 9, and the front end of hitching arm 3 is provided with mount hole 3b '.The connected mode that draw bar 10 and support are 2 is, is connected with support plate 6 on support 2, is hinged with a connector 7 on support plate 6, and root draw bar 10 passes through thread connection with connector 7.The front end of each draw bar 10 is connected to adjusting rod 11, and 11 of draw bar 10 and adjusting rods are thread connection, the front end of adjusting rod 11 be provided with mount hole 11 '.The mount hole 11 of adjusting rod 11 front ends ' be used for joining with the suspension pull bar at tractor rear portion.After adjusting rod 11 front ends are articulated on the suspension pull bar at tractor rear portion,, can regulate the height of girder 1 and support 2 by adjusting the screwing length between adjusting rod 11 and the draw bar 10.

Hitching arm 3 is divided into two sections, and the hitching arm 3 that is divided into two sections is connected by pin 12 by the mode of pegging graft, and promptly hitching arm 3 is connected by pin 12 and constituted by principal arm 3a and the telescopic arm 3b back of pegging graft.At the through hole 3a ' that has on the principal arm 3a more than two, at the through hole 3b that has on the telescopic arm 3b more than two ", pin 12 passes through hole 3a ' and 3b ", principal arm 3a is connected with telescopic arm 3b.The length of hitching arm 3 can be adjusted, and the mount hole 3b ' of the front end of hitching arm 3 is used for being connected with the suspension arm at tractor rear portion.
