Sweet Potato Harvester
Sweet potatoes are an important crop for both food and fuel.sweet potato harvester They are the main source of carbohydrates for human beings and provide much of the nutrition in the diets of people around the world. They are also used as a major ingredient in various foods and beverages such as desserts, bread, muffins, cakes, and cereals. They can be grown in many different types of soil, making them a versatile crop for farmers to grow. However, harvesting sweet potatos is a time-consuming and labor-intensive process. The sweet potato harvester is a machine that is designed to reduce the amount of labor required to harvest the sweet potato and improve production efficiency.
The sweet potato harvester can be divided into three parts: the digging mechanism, the collection and sorting mechanism, and the transportation mechanism.sweet potato harvester The digging mechanism consists of a conveyor belt and a pair of rotary drums, which can dig up to ten feet per minute. The conveyor belt and rotary drums can be operated independently, which allows for a high level of automation.
Once the sweet potatoes are dug, the transporting mechanism moves them to a box or other transportation vehicle. This is a critical step in the harvesting process, since it is common for sweet potatoes to have high damage rates and skin breakage rates during transport. The conveying and separation mechanisms in the harvester can reduce these problems by using a special device to separate the tubers from the soil, which can significantly reduce the rate of sweet potato damage during transport.
Most commercial producers in Louisiana harvest sweet potatoes using two-row mechanical chain harvesters, better known as diggers. These machines require 10 to 12 people to operate, and can harvest up to four acres per day under ideal conditions. However, these harvesters have a number of limitations that prevent them from being used on large scales, including poor ergonomics and low productivity.
Other methods of harvesting include using one-row harvesters and four-row bulk harvesters. These harvesters are more efficient, but can be more difficult to operate and maintain. Both of these harvesters are also more expensive than the two-row diggers.
Lastly, some farmers use vibration digging-type and transfer conveyor-type harvesters. These machines are very efficient, but they can cause damage to the sweet potato skin due to friction between the transfer conveyor and the sweet potato. These factors have led to low usage rates among sweet potato farmers.
To solve these issues, the harvester uses a unique separator that separates the sweet potato tubers from the soil and vines through a series of interlocking rollers. The separator can achieve a separation rate of more than 93%, with a minimal rate of unharvested tubers. Additionally, it can produce a high level of sorting and transportation efficiency by reducing the number of contacts between the conveying chains and the sweet potato blocks. This significantly reduces the damage and skin breakage rates of the sweet potato and increases its yield.
