Enhanced multi-cylinder diesel engine water cooling system structure

Abstract

The invention relates to a reinforced type multi-cylinder diesel engine water cooling system structure used on an agriculture combine-harvester. The reinforced type multi-cylinder diesel engine water cooling system structure comprises a rotating shaft, a water cooling system belt wheel, a bearing, a water cooling system shell body, a water cooling system cover and an impeller, wherein the water cooling system cover is fixed to the water cooling system shell body, a cooling water inlet and a high-temperature water outlet are formed in the water cooling system shell body, a cooling water inlet channel and a high-temperature water outlet channel are arranged in the water cooling system cover, the cooling water inlet is communicated with the cooling water inlet channel, the high-temperature water outlet channel is communicated with the high-temperature water outlet, the rotating shaft is arranged in the water cooling system shell body in a rotating mode through the bearing, the impeller is fixed to the end portion, inside the water cooling system shell body, of the rotating shaft, and the water cooling system belt wheel is fixed to the other end portion of the rotating shaft. The reinforced type multi-cylinder diesel engine water cooling system structure is compact in structure, high in space utilization rate, small in number of parts, convenient to assemble and low in cost, and due to the fact that a small circulating structure is removed out of the system, the leakage points are reduced.

Description

technical field [0001] The invention relates to a water-cooling system structure of a reinforced multi-cylinder diesel engine used in an agricultural combine harvester, and belongs to the technical field of diesel engines. Background technique [0002] The rice harvester is an agricultural machine that uses machinery to complete the harvesting of rice when the rice is mature or close to maturity, according to the agronomic requirements. It is a new type of agricultural machinery researched and developed for the development of new energy sources and to reduce the labor intensity of farmers. It is a low-cost agricultural machinery suitable for the popularization of small four-wheelers in rural areas, and it can harvest rice when it is matched. It shortens the labor cycle of farmers' friends and frees people from heavy physical labor. [0003] In the Chinese market, the most primitive rice harvester diesel engine is converted from a car engine. Its water cooling system is made...

Problems solved by technology

At the same time, the cost of many parts of this kind of structure is relatively high, and there are many joints that are prone to water leakage.

[0004] In order to solve the "boiling" phenomenon, 1. Increase the flow rate of the water pump and cancel the thermostat, but the existing structure cannot be arranged due to insufficient space for the diesel engine

2. Increase the capacity of the water tank: resulting in an increase in cost, and many harvesters cannot increase the water tank due to limited space
