Problems solved by technology

However, the resistance of the four wheels to the ground is different, which in turn leads to different resistances of the hydraulic motors connected to them, so that the flow of the four branches is different, resulting in inconsistent speeds of the wheels when driving straight.

Abstract

The invention relates to the technical field of aquaculture, and discloses a power transmission system of a shore-based feeding robot. The power transmission system is characterized in that a first hydraulic pump is connected with a first hydraulic motor and a second hydraulic motor, the first hydraulic motor is connected with a third hydraulic motor, the second hydraulic motor is connected with a fourth hydraulic motor, hydraulic oil flowing out of a hydraulic pump passes through the first hydraulic motor and the second hydraulic motor and then flows to the third hydraulic motor and the fourth hydraulic motor, output shafts of the first hydraulic motor and the second hydraulic motor are connected through a clutch, when the clutch is closed, the displacement of the first hydraulic motor and the displacement of the second hydraulic motor can be the same, therefore, the flow of the third hydraulic motor and the flow of the fourth hydraulic motor are the same, the rotating speed of the third hydraulic motor and the rotating speed of the fourth hydraulic motor are the same, the moving speed of a left driving wheel and the moving speed of a right driving wheel are consistent, and cross-country straight movement is achieved. The invention further provides the shore-based feeding robot comprising the power transmission system and a control method.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a shore-based feeding robot, a power transmission system and a control method thereof. Background technique [0002] As an important part of my country's agricultural production, aquaculture plays an important role in promoting the development of my country's agricultural economy and improving people's living standards. However, there are still problems such as high cost and low benefit. Therefore, it is very important to reduce the cost of aquaculture. Feed is a modifiable cost in aquaculture, typically accounting for around 65% of aquaculture costs. It plays an important role in reducing the cost of breeding and improving the management of breeding. Feeding methods in traditional aquaculture are manual feeding. It is difficult to accurately control the amount of manual feeding, and it is impossible to ensure uniform feed density in the feeding range. Excessive feeding will...
