Abstract
The utility model relates to a drawing apparatus for miniature wheel type tractor, the structure of which is simple, the carrying capacity is great, and can effective change the stress condition of the connection of the drawing frame and the half axle housing of the wheel axle. Thus the drawing apparatus for miniature wheel type tractor of the utility model which comprises a drawing frame and a drawing fork is characterized in that the utility model also comprises a connecting board, one end of which is connected on the draw-bar seat of the raiser, and another end is connected with the drawing frame. When the structure is used, because a connecting board is arranged on the drawing frame and the draw-bar seat of the raiser of the tractor, the drawing fame and the connecting board form a steady triangular support by the tractor body, thus the stress condition of the drawing frame is greatly improved, the intension of the drawing frame is intensified, the carrying capability of the drawing frame is increased and also the structure of the drawing frame is simple.
Description
Technical field
The utility model relates to a kind of agricultural machinery parts, relates in particular to a kind of draw gear of the 15-28 of being applicable to horsepower minitype wheeled tractor.
Background technology
At present, the minitype wheeled tractor that uses in the Tendency of Agricultural Machinery in China field adopts drawbar frame vertically to be connected on the left and right sides axle shaft housing of wheel shaft by bolt mostly, articulates trailer by towing fork again.This structure makes drawbar frame become to be connected in the cantilever on the described wheel shaft axle shaft housing, the bolt that connects drawbar frame should bear in distraction procedure because the pulling force that traction causes, bear drawbar frame again and shift formed shearing force because of trailer weight, the stress condition very severe, especially even more serious when pulling single-wheel axle trailer, drawbar frame and axle shaft housing foundry goods be defectiveness slightly, just danger can occur.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, load-carrying capacity is strong, can effectively change the draw gear of the minitype wheeled tractor of drawbar frame and wheel shaft axle shaft housing junction stress condition.
For this reason, minitype wheeled tractor draw gear of the present utility model comprises drawbar frame, towing fork, it is characterized in that: it also comprises connecting panel, and this connecting panel one end is connected in lifter top rod seat, and the other end is connected in described drawbar frame.
Adopt this structure, because the lifter top rod seat on drawbar frame and trac. is provided with connecting panel, make drawbar frame and connecting panel by dilatory fuselage, form stable gusseted, thereby improved the stress condition of drawbar frame greatly, strengthened the intensity of drawbar frame, improved its load-carrying capacity, its structure is also fairly simple.
Description of drawings
Fig. 1 is the Facad structure scheme drawing of the utility model minitype wheeled tractor draw gear.
Fig. 2 is the birds-eye view of minitype wheeled tractor draw gear shown in Figure 1.
Among the figure
1. drawbar frame 2. connecting panels 3. lifter top rod seats 4. connecting bores
5. towing fork 6. articulates bar 7. drawbar frame tie bolts 8. traction bearing pins
The specific embodiment
As shown in Figure 1 and Figure 2, minitype wheeled tractor draw gear of the present utility model comprises drawbar frame 1, towing fork 5, and connecting panel 2; Drawbar frame 1 is connected on the axle shaft housing of trac. wheel shaft by drawbar frame tie bolt 7, towing fork 5 is hinged with drawbar frame 1 by means of traction bearing pin 8, make towing fork 5 to rotate around traction bearing pin 8, so that can better adapt to different road conditions during breakdown trailer, connecting panel 2 one ends are connected in lifter top rod seat 3, and the other end is connected in described drawbar frame 1.
On connecting panel 2, can be provided with at least one connecting bore 4.When the effect of connecting bore 4 is that drawbar frame 1 is installed on different trac.s, adjust the connection length of connecting panel 2.The position of connecting bore 4 is determined according to needed connection length.
Can have hanging part on connecting panel 2, the other end of this hanging part is connected with described towing fork 5.This hanging part is mainly used in suspension traction fork 5, to make things convenient for articulating of trailer, avoids manually holding up towing fork 5 and articulates trailer heaviness, the very dangerous again shortcoming of trouble.The length of hanging part is advisable to keep towing fork 5 to be horizontal.Described hanging part can be for articulating bar 6, and this articulates bar and can be connected with towing fork 5 when articulating trailer for flexibly connecting with being connected of described towing fork 5, takes off afterwards.Described hanging part also can be for articulating chain, articulating other parts that spring etc. can hang towing fork.This draw gear is simple in structure, bearing capacity is high, articulate convenience, safety is good, economical and practical.
