Description

Technical Field

[0001] The invention relates to the technical field of agricultural vehicles, in particular to an oil tank counterweight type frame suitable for a small corn breeding detasseling machine. Background Art

[0002] Due to the rapid development of the seed corn industry, the level of agricultural mechanization has increased rapidly. As the national corn seed production base, the Hexi Corridor mainly produces corn seeds on small plots, and the emasculation period of seed corn is very short, only about 15 days. Due to the geographical restrictions of the Hexi Corridor, large-scale corn breeding emasculation machines cannot be used in small fields, which restricts the advancement of agricultural mechanization. Manual emasculation is usually used, which is labor-intensive and has low production efficiency. The hydraulic oil tank and counterweight are installed at the rear of the large corn emasculation machine frame. The overall vehicle length is 5500mm, and the turning radius is about 8mm. The turning radius is large and it is not easy to turn. In addition, the hydraulic oil tank is at the rear, and the volume of the hydraulic oil tank is small (0.054m 3 The oil return filter and oil return diffuser are installed inside the hydraulic oil tank. The hydraulic pipeline is long, which increases the oil temperature of the hydraulic oil during operation. The overall length of the tank counterweight frame is 3120mm, and the turning radius is small, about 6m. The H-shaped oil tank formed at the rear of the frame is at the support part of the rear wheel. The rigidity of the vehicle body is good. In addition, the oil tank capacity is large (0.135m 3 ), better heat dissipation and shorter pipelines.

[0003] In order to reduce labor costs and improve labor efficiency, it is urgent to develop a small corn detasseling machine. The first design point of the small corn detasseling machine is that it has a smaller turning radius and vehicle distance during operation, and the whole vehicle structure must be compact.
