The Automatic Potato Harvester

The automatic potato harvester is a machine that automatically separates and conveys potatoes from the soil to be collected by a transport vehicle.automatic potato harvester It has the advantages of lower mechanical damage, zero bruising, and high productivity. It is an ideal machine for the harvesting of underground root crops such as potatoes, sweet potatoes and garlic. It is a highly efficient farm machinery that can be used in large-scale farms and commercial use.

The process of potato harvesting is a complex and time-consuming process.automatic potato harvester This involves a combination of factors such as soil characteristics, weather conditions and the harvester’s design. The harvester’s performance can be improved by adjusting its mechanical parameters. These include the forward speed, conveyor speed, digging angle and digging depth. The study of the optimal design of these parameters is a key issue in improving harvesting efficiency.

In the research on potato harvesters, it is essential to determine the interaction forces between soil-potato bodies and the structural elements of the machines.automatic potato harvester Various methods have been employed for this purpose, such as physical experiments and DEM simulation software. A DEM model simulates the dynamics of the potato-soil separation and conveyance process within a harvester, allowing engineers to analyze the effects of the different working parameters on the performance of the machinery.

According to Muhhamad et al., the mechanical harvest of potato relative to manual harvest is 65% cheaper at harvest time and 45% cheaper in terms of overall operating costs. It also imposes a lower rate of mechanical damage on the tubers, resulting in fewer bruising injuries. It is important to note that the mechanical harvesting process requires prior haulm killing, which inflicts some damage on the immature tubers.

During the first stage of the transportation process, the harvested potatoes are separated from the soil by the potato harvester’s conveyor belt, soil separator, and other mechanisms. This is a critical phase that affects the quality of the final product. In addition to the impact of the conveyor speed, the linear velocity of the potatoes and the total mass of the soil-potato mixture are also critical.

As the harvester moves down rows of the crop, adjustable steel discs are set to cut any debris or foliage that may block its mouth. This ensures that the potatoes are not obstructed and moved into the elevator web. Once the potatoes are transferred to the elevator, a sieve removes the remaining soil and leaves. The resulting granular material is then conveyed into the trolley and loaded onto the transport vehicle for transport to the processing plant.

The results of the study on the mechanical harvesting of potatoes suggest that the optimum working parameters for the machinery are the forward and conveyor speeds, the digging angle and the digging depth. The optimum values of these parameters can be determined by analyzing the behavior of the equipment under varying loading and operating conditions. The authors concluded that these parameters can help improve the efficiency and yield of the harvester by minimizing the amount of potato bruising and soil-potato contact.
