Improve the Performance of the Potato Picker
The potato picker is a machine designed to harvest potatoes using mechanical means rather than manual labor.potato picker The machine cuts furrows in the field and collects the potatoes, which are then transferred into bags or trailers for transport. It can also be used to sort the potatoes by size or remove damaged ones, which improves crop quality and increases agricultural yields. However, there are some concerns about the safety of this machine as it requires large amounts of power and may cause injuries to workers. In addition, the mechanical process of harvesting may damage the potato tubers. Consequently, researchers are developing new technologies to improve the performance of the potato picker.
A common way to harvest potatoes is through manually removing them from the ground by hand, which can be dangerous and time-consuming.potato picker Other methods of potato harvesting use machinery to cut the tubers from the soil, a process that can be faster and more precise than manual harvesting. However, these machines can damage the potato tubers due to their design. To address this issue, researchers are developing innovative technology to improve the performance of potato harvesters and prevent injuries to workers.
To achieve this, researchers have developed a system that uses machine vision to monitor the quality of harvested potatoes. It uses high-speed cameras and advanced image processing algorithms to detect external defects such as greening and mechanical damage. It can also identify diseases such as Rhizoctonia and common scab. This machine can process up to 12 t/h of potatoes, which is much higher than the rate achieved by manual sorting.
In addition to detecting defects, this machine can also detect the presence of certain diseases that require treatment before they spread, which is particularly important in areas where disease incidence is high. The machine can then automatically impose the appropriate treatments to reduce the spread of these pathogens. It is also capable of grading potatoes according to their internal quality, which is essential for improving post-harvest storage and reducing crop losses.
Several factors influence the quality of harvested potatoes, including soil conditions and the force required to extract them from the ground. Using a soil conditioner can help to loosen the soil and reduce traction resistance, while designs that minimize soil adhesion and friction between potatoes can improve harvest efficiency by up to 22%. In addition, the potato picker must be able to overcome any traction losses caused by obstacles in the field.
To determine optimum working parameters for the potato picker, researchers used a Box-Behnken response surface optimisation test to analyse the relationship between the spring-finger speed, forward speed, and embedded depth. The results of the test showed that the optimal values of these variables were 20 r/min, 0.6 m/s, and 70 mm. A validation test was conducted to verify the optimum parameters and found that they were in good agreement with the prediction of the model. In addition, the test results indicated that the optimum working parameters reduced the loss rate and wounded potato rate by 4.98%.
