Electric control system of coconut sheller

Abstract

The invention discloses an electric control system of a coconut sheller. The electric automatic control system comprises two parts including a main circuit and a control circuit, wherein the main circuit comprises elements, such as an air switch, an AC contactor, a thermal relay and a motor, and the control circuit comprises the elements, such as a programmable controller, an analog-to-digital conversion module, a photoelectric switch, change-over switch and a pressure sensor. In the electric control system, the photoelectric switch for detecting existence of a coconut is used as a starting signal of an automatic shelling process, depth of inserting into the coconut of a blade is detected through the pressure sensor, a pressure jump signal generated when the blade pricks a wooden shell ofthe coconut is taking as starting of shelling, so, the electric control system is more accurate and reliable than the conventional observation by naked eyes. The electric control system provided by the invention has the beneficial effects of changing artificial operations of a shelling work into automatic operations, realizing automation of such production process and laying a foundation for realizing total automation of coconut processing enterprises.

Description

technical field [0001] The invention relates to an electrical control system of an agricultural product processing machine, in particular to an electrical control system of a coconut peeling machine. Background technique [0002] The main planting area of ​​my country's coconut is in Hainan, and the planting area and fruit output both account for more than 90% of the country's total. Coconut fruit is the fruit of the coconut tree, commonly known as coconut. Coconut trees are full of treasures. Coconut flower, coconut fruit, coconut leaf, coconut wood and coconut root can all be used. Coconut fruit is the most widely used. Its coconut meat, coconut water, coconut shell and coconut shell are used in different applications. The coconut food processing industry, which uses coconut meat and coconut water as raw materials, is one of the important pillars of Hainan's food industry. Therefore, the coconut industry plays an important role in the economic development of Hainan. [...
