Boat type tractor hull installed on frame

Abstract

The invention discloses a boat-type tractor hull installed on a frame, which comprises a hull main body, the hull main body is provided with a concave curved surface structure used for reducing resistance during steering or reversing of a boat-type tractor, the hull main body comprises a hull floor and a hull side plate, and the hull floor and the hull side plate are integrally connected through a curved surface. A bow frame mounting plate, a hull frame mounting plate and a stern frame mounting plate which are used for mounting the frame are fixedly mounted on the hull main body, a stern plate is fixedly mounted at the stern of the hull main body, and frame mounting seats are fixedly mounted on the bow frame mounting plate, the hull frame mounting plate and the stern frame mounting plate. Compared with the prior art that a transmission system is supported by a ship shell, an existing frame mounting structure is adopted, so that the hull is simpler and lighter, the whole modeling is streamlined, the resistance is greatly reduced during paddy field operation, and meanwhile, the structural strength is better.

Description

technical field [0001] The invention relates to the field of boat tractor accessories, in particular to a hull of a boat tractor installed on a vehicle frame. Background technique [0002] The boat tractor started in the 1970s in our country. It uses the floating-sliding working principle to carry out paddy field operations. It is one of the main agricultural machinery used in the rice-growing areas in southern my country. Existing four-wheel drive boat tractor mainly adopts the mode that the hull supports the whole transmission system. This method has the following technical problems: 1. The entire transmission system is supported by the hull, which causes problems such as deformation and resonance in the hull structure; 2. The weight of the ship adjustment plate is heavy, which makes the movement cumbersome when driving or reversing, and also affects the operation of the tractor. Efficiency; 3. The problem of excessive resistance caused by the large hull; 4. The problem o...
