Technical Field

[0001] The utility model relates to the technical field of tractors, in particular to a safety frame lower curved beam structure and a tractor. Background Art

[0002] Tractors are commonly used in agricultural production. Some tractors lack a cab, so a safety cage is essential. The cage primarily protects the driver, creating a safe space for self-rescue and escape, ensuring their safety. Furthermore, the cage minimizes damage to the tractor in the event of an accident and prevents or mitigates the risk of the tractor rolling over.

[0003] In the prior art, the lower curved beam of the mounting frame is a straight frame structure in a vertical state. This structure occupies a large space, causing squeezing or even interference with the installation of other components (such as fenders), affecting the layout and operating space of the entire machine.

[0007] The beneficial effect of the utility model is that during installation, the lower ends of the two curved beams are fixedly installed on the suspension assembly of the tractor, and the vertical installation state of the curved beams is maintained, so that avoidance space is formed on the outer sides of the middle ends of the two curved beams to avoid the installation of other parts such as mudguards, thereby improving the technical problem that the lower curved beams of the existing mounting frame will squeeze the installation of other parts of the tractor and affect the layout and operation space of the entire machine, reducing the space occupancy rate and providing a larger operation space for the layout of the entire machine.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, it also includes a crossbeam, which is transversely arranged between the two curved beams, and has two ends fixedly connected to the middle ends of the two curved beams.

[0010] The beneficial effect of adopting the above further solution is that the two curved beams are connected simultaneously by the cross beam to form an integral frame structure, thereby improving the structural strength of the entire safety frame.

[0011] Furthermore, both ends of the beam are fixedly connected with a plate, and the two plates are fixedly connected to the middle ends of the two curved beams respectively, and the area of ​​the plate is larger than the cross-sectional area of ​​the beam.

[0012] The beneficial effects of adopting the above further solution are: expanding the fixed connection area by pasting the plate, improving the connection fixity, and releasing stress concentration, thereby greatly improving stability and strength.

[0013] Furthermore, the two curved beams each include a lower support section, a middle avoidance section whose lower end is fixedly connected to the upper end of the lower support section, and an upper support section whose lower end is fixedly connected to the upper end of the middle avoidance section, and the outer sides of the two middle avoidance sections form the avoidance space.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that during installation, the lower ends of the two lower support sections are fixedly installed on the suspension assembly of the tractor, and the vertical installation state of the curved beam is maintained, so that the outer sides of the two middle avoidance sections form avoidance space to avoid the installation of other components such as mudguards, thereby improving the technical problem that the lower curved beam of the existing mounting frame will squeeze the installation of other components of the tractor and affect the layout and operation space of the whole machine, reducing the space occupancy rate and providing a larger operating space for the layout of the whole machine.

[0015] Furthermore, the upper ends of the two lower support sections are fixedly connected to the lower inclined sections, the lower ends of the two lower inclined sections are fixedly connected to the upper ends of the corresponding lower support sections, and the upper ends are inclined inwardly toward each other and fixedly connected to the lower ends of the corresponding middle avoidance sections.

[0016] The beneficial effect of adopting the above further solution is: the lower support section and the middle avoidance section are connected by the inclined lower inclined section to achieve stable support for the middle avoidance section, and the inclined setting of the lower inclined section can relatively increase the size of the avoidance space.

[0017] Furthermore, the two lower supporting sections and the corresponding lower inclined sections are fixedly connected with ribs.

[0018] The beneficial effect of adopting the above further solution is that the strength of the connection structure between the lower supporting section and the lower inclined section is improved by the ribs.

[0019] Furthermore, the lower ends of the two upper support sections are fixedly connected to the upper inclined sections, the upper ends of the two upper inclined sections are fixedly connected to the lower ends of the corresponding upper support sections, and the lower ends are inclined inwardly toward each other and fixedly connected to the upper ends of the corresponding middle avoidance sections.

[0020] The beneficial effect of adopting the above further solution is: the upper support section and the middle avoidance section are connected by the inclined upper inclined section to achieve stable support for the upper support section, and the inclined setting of the upper inclined section can relatively increase the size of the avoidance space.

[0021] Furthermore, the outer sides of the middle ends of the two curved beams are fixedly connected with mounting blocks.

[0022] The beneficial effect of adopting the above further solution is that the installation of the mudguard waiting avoidance component can be achieved through the installation block.

[0023] Furthermore, both of the curved beams are provided with a plurality of mounting points.
