5. As per claim 1, the drive section consists of motor (5) and chain sprocket arrangement (8). There are two compound sprockets used to receive the power from motor (5) and transmit the same to the caged wheels (2). , Description:Field of Invention
The present invention pertains to RC Controlled Agrobot, a remotely piloted electric vehicle which can be used for pesticide, insecticide or any other spraying in the field of crops like Tomato, Brinjal, Ladyfinger, green chili, etc., whose height is less than 3 feet. The invention aims at providing safety to farmers while spraying the pesticides or insecticides by using a bot which can be operated using a Radio Controller.
Background of the Invention
Indian Farmers currently use backpack sprayers which are actuated by either lever or a small motor pump. Maximum of 20 liters of pesticide cab be carried in these sprayer tanks which can be applicable for very small area of the crop. Also, due to continuous muscle movement farmer may experience muscular disfunction. Pesticide spraying is one of the most important aspect of a better cultivation practice to keep the crops healthy and for better yielding of the crop. These pesticides are used as precautionary measure to prevent plant diseases and pest. Unfortunately, most of the farmers use chemical pesticides and fertilizers for their crops.
Pesticides can enter the body of the farmer through inhalation or through eyes or absorption by skin. Hence, farmer must be very careful while dealing with chemical pesticides especially, during mixing or application of pesticides. As these involve direct contact with the pesticide, farmer may carry the traces of the pesticide directly through inhalation or by skin. There has been increasing application of robots in industries and commercial sectors to substitute the human labour and make it more efficient and effective. The invention proposes an agricultural robot (Agrobot) to minimize the human intervention in pesticide spraying. An electric pesticide spraying vehicle as mentioned in CN102726359A can be modified to meet the requirement. The Agrobot will be operated using an RC Transmitter from a distant place. A model with pesticide spraying vehicle, which comprises a vehicle frame and traveling wheels fixed under the vehicle frame via a traveling wheel support as mentioned in CN202059912U. The bot can be attached with a camera which can live stream the video for better operation of the observability.
Summary of the Invention
The present invention aims to provide better safety and develop a more suitable bot for pesticide spraying in the fields.
The specific objective of the invention is to design an Agrobot which can be operated using electrical motor instead of conventional IC engines which may cause environmental issues.
Brief Description of Drawings
The invention will be described in detail with reference to the exemplary embodiments shown in the figures wherein:
Figure 1: Front view of Agrobot with all components
Figure 2: Isometric View of Agrobot
Detailed Description of the Invention
The embodiment of the present disclosure provides an RC Agrobot whose structural frame (1) is fabricated using Mild steel (bright). The frame was designed to withstand a load of 150 kgs. All the members were connected using welded joints.
The invention includes caged wheels (2) to avoid the skidding of the wheels even in the wet fields. These caged wheels are made from MS bright. The diameter of these caged wheels is 10 inch and thickness of each stringer is 0.2 inch. These wheels are mounted on a shaft (3) each of diameter 25 mm. These shafts are hardened for better mechanical properties. The shafts are supported by two ball-bearing (4) on either side of the shaft. These bearing are fastened to the Frame using M10 bolts.
Drive unit for this bot has two 350kv DC motors (5) which are connected to Lipo batteries (6) through Cytron Dual channel 60A driver board (7). The motion transmission from the drive section to wheels is achieved using chain and sprocket mechanism (8). A compound sprocket is mounted on rear wheel which is directly engaged with the DC motor and another sprocket is engaged with the left-over sprocket of the compound gear. Skid steering is considered for the steering mechanism of the bot. The sprockets are hardened for better durability and improved performance.
The Storage tank (9) was designed to contain 50 liters of the pesticide which can be evenly distributed for over three fourth (3/4th) acres for each full tank approximately. A motor pump (10) of 0.1 HP was used to pressurize the pesticide and which is connected to a separate battery included inside the tank. The sprinklers are connected to Aluminum pipe (11) and are provided with different types of sprinklers nozzles (12) to suit the crop. A total of 4 Types of nozzles are used which include Flower Nozzle, Y-type nozzle, Straight nozzle, Cut nozzle. The piping is done using Silicone tubes (13) for better durability.
With reference to figure 1, the components of Agrobot are presented in the front view. This indicates Li-Po Batteries, pesticide storage tank, sprinkler nozzle, Cytron smart drive with receiver, frame of the agrobot, caged wheels, chain sprockets, wheel shaft and bearings. Thus, the design ensures with high torque and with regulated speed. The Sugarcane juice harvesting machine of the present invention discloses its usage with reduced number of gear sets with highest torque and with regulated speed at the crusher. This invention reduces the machine material cost, weight of the machine and vibrations occurred.
