Compared with the prior art, the beneficial effects of the utility model are that: the main frame in this application is the section bar structure, compares the rack construction of panel type, and the frame of section bar structure mainly is to splice the structure that welds into the box to the panel that the shape is complicated and replaces simple structure's large cross-section rectangular pipe, and the handling capacity and welding volume obviously reduce, have reduced the preparation cycle and the cost of product, have improved the production efficiency of volume production.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of another view angle of the present invention.

In the figure: the welding device comprises a first rectangular pipe 1, a front oblique support rectangular pipe 2, a rear oblique support rectangular pipe 3, a reinforcing support rectangular pipe 4, a second rectangular pipe 5, a rear vertical rectangular pipe 6, a rear rectangular pipe 7, a rear welding transition plate 8 and a front welding transition plate 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a main frame of a cotton picker comprises a first rectangular pipe 1 with a large cross section for mounting a front axle assembly, a front inclined support rectangular pipe 2, a rear inclined support rectangular pipe 3, a rear vertical rectangular pipe 6 and a rear rectangular pipe 7, wherein the first rectangular pipe 1 is horizontally arranged, the front inclined support rectangular pipe 2 and the rear inclined support rectangular pipe 3 are arranged in a V shape, one end of the rear inclined support rectangular pipe 3 is welded with the first rectangular pipe 1, the other end of the rear inclined support rectangular pipe 3 is welded with a second rectangular pipe 5 which is horizontally arranged, the first rectangular pipe 1 is vertical to the second rectangular pipe 5, a reinforcing support rectangular pipe 4 is welded between the second rectangular pipe 5 and the front inclined support rectangular pipe 2, the rear vertical rectangular pipe 6 is vertically arranged with the rear rectangular pipe 7, the rear vertical rectangular pipe 6, the rear rectangular pipe 7 and the rear inclined support rectangular pipe 3 are welded into a triangular structure, one end of the rear rectangular pipe 7 is welded with the first rectangular pipe 1, the other end and the engine installing support of rear portion rectangular pipe 7 are connected, and is concrete, strengthen supporting the anterior frame that is of rectangular pipe 4, parts such as cotton picking head and driver's cabin are installed in the frame of front, and back bearing rectangular pipe 3 connects into the back frame with second rectangular pipe 5, and parts such as cotton-padded box/packing mechanism, engine and rear drive axle are installed in the frame of back, strengthen supporting the main frame that rectangular pipe 4's setting made front and back two parts and link into a whole, increased the bulk strength of main frame. In the traditional plate structure, the shape of a plate at the main bearing part is complex, the blanking period is long, and the sectional material can be directly cut into the required length and shape; the frame of panel structure, still need to piece into the structure of box after panel processing, the preparation cycle is longer and the welding volume is great, and can the direct weld after the section bar processing, consequently, the main frame of the section bar structure that this application provided can reduce section bar processing volume and welding volume, has reduced the preparation cycle and the cost of main frame, has improved the production efficiency of volume production.
