Minimize the Material Handling Time of Agricultural Finished Goods

Agriculture is the backbone of India. Nowadays, in agriculture facing many problems, so initial the project starts with the preparation of a questionnaire. According to the problem facing agriculture in Ayikudi village, It covers nearly 425 hectors of agricultural lands surrounded by it. From the questionnaire, the problem is identified in the field of material handling in which the raw materials, finished products like vegetables, coconut, banana, etc are difficult to transfers the products from the field to outside of the field, the project approaches to implement the slat chain conveyors system in the agriculture field to transfers the materials and products from the field to outside of the field, before the implementation of conveyor system in agricultural filed. The methodology, initial step is to defines about the agricultural field from the data gathered it leads to locate the conveyor at optimal point to cover all landholders, next step is to mathematical model is done, and next step is to design of conveyor is done, and next step is cost estimation for overall expenses is estimated for implementation and the final step is to simulation process for the manual and conveyor system implementation is done, it results that the time, cost and manpower reduce in the agriculture field is compared with manually carried by load carriers.


INTRODUCTION
The word 'Agriculture' is derived from the Latin word 'Agri' means Land or field and 'Culture' means cultivation. It means the science and art of producing crops and livestock for economic purpose. The history of dates back to Indus Valley Civilization and even before that in some places of Southern India. India ranks second worldwide in farm outputs. As per 2018, agriculture employed 50% of the Indian workforce and contributed 17-18% to the country's GDP. In today's world where transportation is perhaps one of the most utmost elements for the business to succeed, people are always in search of better, faster and cost-effective techniques of transporting, tracking and processing their goods. In recent years, the conveyor belt system has emerged as one of the best ways of transporting the product. This system consists of two or more drums that are also referred to as pulleys with a conveyor belt i.e. he carrying medium and it rotates around the drums. The belt is propelled by one or two of the pulleys. The pulley that powers the belt is called the drive pulley and the other is called the idler pulley. The conveyor belt is categorized intotwo classes, one that transports general material and the other that is responsible for taking agricultural material such as sand, ore, coal, salt, grain and much more from one place to another. Uses of conveyor in the agricultural community. The uses of a conveyor system agricultural community are numerous. It is used in the feeding process that processes or freezes vegetables, fruits, and other agricultural products for packing to be sent to the retailers or other process plants. Besides this, these belts are effectively being used for loading bulk quantities into trucks to get them transported to their final destination. Bean market is another place, where conveyor belt scales are used in a large number. Additionally, these belts are also to load out the soybeans into the trucks that carry them to the end process.

[1] Discussed to minimize workin-process. It shows that the choice of layout has a direct impact on work-in-process accumulation, manufacturing lead time, achievable throughput rates, and required material handling capacity. It has two methodology sources: the processing departments and the material handling transporter. In both cases, WIP accumulation is determined by • Variability in the arrival process. • Variability processing/ transportation time.
• Utilization of the departments and the transporter. The objective is to minimize work-in-process. the model to explore the relationship between layout configuration and operational performance. It showed that the conventional criterion of selecting layouts based on average material handling distances can be a poor indicator of queuing effect.

The conveyor is at a specific distance from floor level which runs at a very low speed so that it becomes convenient and flexible for the operator to assemble the vehicle parts while the conveyor is moving. Then the vehicle is manually unloaded at the last station. Conveyor Design Steps: Conveyor chain the following point should be considered. Chain design, Calculating Chain Pull Attachment, Coefficient of Friction, Service factor, attachments, finite element analysis, Testing, Inspection Function Testing, Load Testing. It argued that by integrating information technology with production processes many undesirable material handling activities could be easily avoided, also the companies would be able to attain increased space efficiency on the production/assembly area and decreased work in process.

Slat conveyors
A chain conveyor works on the principle of the interconnectivity of a chain connects each gear, resulting in a smooth carrying process. The chain conveyor has a series of gears connected into a continuous system by the chain. Typically, each gear has teeth that deliver a free rotational interface with the chain. A slat conveyor is a two-strand chain conveyor with slats connected to the chain and a guiding system for the slats. This creates a smooth surface to which tooling details or fixtures can be mounted to hold parts in the desired position. Slat Conveyors are used in horizontal conditions and operating at relatively slow speeds. They are generally used to move items that are not typically conveyable on rollers or belts, due to an irregular shape or bottom condition. So these approaches help to solve the problem of material handled in the agriculture field.

Inference:
In the photographic view of the agriculture field, the total area looks to be in irregular shape and size, so it divided. According to shape is divided into the number of sections to find out the co-ordinates of the agriculture field.

Inference
From point x and y, the conveyor system is initiated to start the implement at the point.

Basic Requirements
To enable the most suitable chain to be selected for a particular application, it is necessary to know full application details such as the following: • Type of conveyor.
• Conveyor centre distance and inclination from the horizontal. • Type of chain attachment, spacing, and method of fixing to the chain. • Number of chains and chain speed. • Details of conveying attachments, e.g. weight of slats, buckets, etc. • Description of material carried, i.e. weight, size, and quantity. • Method of feed and rate of delivery.

D. Cost Estimation:
Projects bring risks, and risks bring unexpected costs. Cost estimation is the process that takes those factors into account and calculates a budget that meets the financial commitment necessary for a successful project.   Return on investment (ROI) estimates the gain or loss generated on an investment relative to the amount of money invested. ROI is usually formulated as a percentage and is typically used for personal financial decisions, to compare a company's profitability or to compare the efficiency of different investments.

E. Simulation
Flexsim software is used to simulate the load carried by manual and conveyor system used in the agricultural field.

Inference:
It shows that the load carried by manual process simulated in the flexsim software.

Inference:
This graph shows the time to carry the load manually as the existing method and proposed method as implementing the material handling conveyor system in the agricultural field.  This project, it shows about the time taken by manually the load carried by load carriers in the agricultural field is analyzed and by implementing the material handling conveyor system in the field, it leads to reduces the time, cost and man-power. Scope and future works This project leads to move towards the future work as the Design and Modeling of a portable conveyor system to the agricultural field. The conveyor system which will fold one another moves with the help mechanized vehicle. It may handle at the outside of the agricultural field. The feeder (conveyor) will move into the agricultural field from which the material will transmit. The feeder conveyor mechanized vehicle will cover the nearby all villages.
