Field of the Invention This invention relates to a fruits harvesting device for example coconut and the like fruits from the trees. Description of Prior Art Harvesting of the fruits for example coconut and like fruits is done mainly through the human labour, where a labourer climbs up the tree with the help of a rope and plucks the fruits from the tree. Another method is that a sickle is tied up at the top end of a long bamboo pole and the sickle is used to cut off the fruits from the trees. Yet another method is that a ladder is placed against the tree and the labour climb up the ladder in order to pluck the fruits from the tree. Still another method of harvesting the fruits for example coconut and the like fruits is done by the persons by using the mechanical device either to pick the fruits from the tree directly, A device disclosed in US patent no, 5301459 comprises an upper engagement member and a lower engagement member which can be opened or closed to engaged an upper and lower portion of the vertical member/ tree respectively. An extension/retraction member is connected to the upper and lower engagement member. The extension/retraction member extends or retracts to very the distance between the upper and lower engagement members. The upper and upper engagement members are provided with a vertical stands mounted on a box type platform. A circular ring having a platform provided therewith is provided with the central support such that to surround the stem of the tree for providing a round platform aroimd the tree so as to ease the operation of plucking the fruits. Another device disclosed in the US patent No. 6443196 comprises wwy boom members secured with each other. The lower end of the first boom memlx r is secured with the mounting firame mounted on a vehicle like a crane. A working U)t>l head is provided at the top end of the second boom for providing a base platform to the user during the operation of the device. Hydraulic cylinders are provided between the first boom and the moimting base of crane for up and down movement of the Inst boom. Similarly hydraulic cylinders are provided between the second and Iksl boom for providing up and down movement to the second boom during operation ol the device. Hydraulic fluid conveying pipes are provided between the hydraulie eyhnders and hydraulic fuel container for operation the hydraulic cylinders as and w hen i cquired by the user of the device. Disadvantages associated with the prior art There are disadvantages associated with the prier art. One of these ch sad vantages is that the conventional method/devices are not capable to withhold tlie ioati of the fruit pickers and the fiiiit. Another disadvantage is that conventional method/devices are thai there is a scarcity of labour and therefore it is very difficult to pluck/harvest up the iVuiis as and when need is arises. Yet another disadvantage is that the conventional method/devices aie time consunraig and costly and therefore the maintenance of fruit farms such as eoeonut and the like fruits are very costly. Still another disadvantage is that the conventional method/devices ai e very dangerous and causes accidents during the harvesting of the fruits. Another disadvantage is that the conventional method/devices degrades the quality of the fruits as the fruits fall down during the harvesting process. Yet another disadvantage is that some of the conventional devices are not easily transportable and are costly and the maintenance of the conventional devices also very high. Advantages and Objects of the Invention Therefore the main object of the present invention is to provide a fruits harvesting device adapted to be moxmted on a tractor for harvesting the fruits for example coconut and the like fruits. Another object of the present invention is to provide a fruits harvesting device which is simple in construction, cheap in cost and maintenance thereof is very easy. Yet another object of this invention is to provide a fruits harvesting device which is easily transportable and can be transported to coconut farms due to the movability of the tractor. Yet another object of this invention is to provide a fruits harvesting device which can be easily demounted from the tractor during the offseason of the fruit harvesting. Still another object of this invention is to provide a fruits harvesting device which can be easy in operation, take less time to harvest maximum fruits, and solve the labour related problems.
