THESIS RICE TRANSPLANTER

My study is based on theoretical development of mechanical rice-transplanter and the basic design on the CAD-CAM software. Octavo Anna Katrina O. In order to improve the picker efficiency, the picker assembly is now spring loaded with a seedling pusher. When the rice transplanter eill move forward the padded wheel will get rotate. It oscillate at certain angle and it is called as fixed fork mechanism. Padded Wheel Gear wheel drive The belt drive is used to power transmit so that the power will betransmitted.

Design, Moving velocity, Efficiency. The picker assembly can be disengaged so that the transplanter can run while the picker assembly, seedling feeder assembly, and the tray indexing assembly are on hold. As the planting finger will oscillate, it will pick the nursery seed from the seedling mat and planted in mud. If this operation is not done in time the yield goes down. Automatic Rice Transplantation Machine. Rice Transplanter Design http: My study is based on theoretical development of mechanical rice-transplanter and the basic design on the CAD-CAM software.

The new system is labour efficient. Padded wheel provided with six fins, when the manpower will push the machine the wheel will rotate with the fins and hence gear will rotate and power will get transmitted.

A design of an ergonomic rice transplanter (2008)

One of the reason behind this is the cost of labourship, availability of labours and the expenses during the farming. Now, we will compare the plantation rate of machine transplantation process with the manual plantation process.

The country has several existing transplanters under two general categories: The planting finger is designed in such a way that nursery seed should be easy to pick during the motion and also it should pick during the downward motion only. The design will be little complex due to the relative driving between the padded wheel and spur gear.

The authors adapted the standard size tray to eliminate the time required in cutting seedbeds before transplanting. The process of manual ricetransplantation is not so efficient as compared to the mechanical ricetransplantation.

As the power will get transmitted to the smaller gear, it will rotate. It will be the time efficient system. A cost and benefit was further made and it was verified that upon acceptance of the mechanization, farmers can save a significant amount of more than Php 1, thdsis hectare. The larger gear is in engagement with the smaller tesis by using the belt drive.

Design involved the selection of padded wheel, spur gear assembly, belt drive and base design.

The design for an ergonomic rice transplanter that could cater to the needs of tramsplanter customer farm owners as well as the user farmers was then sought after and was formed by incorporating the functional requirements of a rice transplanter with ergonomics as well as usability principles.

In practicing the said method however, farmers are exposed ttransplanter musculosketal disorders as well as back problems due to the repetitive bending as well as the awkward posture needed in performing the task.

For the performance test however, transplantef evaluation conducted on the prototype unit showed an output capacity rate of 0. This is part of our updated Privacy Policy. My study is based on theoretical development of mechanical rice-transplanter and the basic design on the CAD-CAM software.

Machine transplanting using rice transplanters requires considerably less time and labour than manual transplanting.

As the drive is provided by the worker it will not have high speed and transplaner through this gear arrangement we have increase the planting finger speed. It is the cost efficient system. In order to improve the picker efficiency, the picker assembly is now spring loaded with a seedling pusher. Considering the present scenario, the labour are not easiy available, as such time these system will be the need for farmers.

For capacity, the authors mounted an engine to increase the planting speed and reduce ergonomic hazards since the repetitive push and pull motion is eliminated.

We have ideally consider that 12 hrs will rics to plant the single hectre of land by using 20 skilled labour. Octavo Anna Katrina O. For the calculation process we have done few assumuptions such as moving velocity and padded wheel diameter.

Design, Moving velocity, Efficiency. Under the ergonomic evaluation, the drudgery felt was reduced as the manner of operating the transplanter was modified from push and pull to minimal pushing, as engines were incorporated in the design.

It is the distance between two nursery seed point along the motion of the machine. The system is easy for handling.
