The world’s first tea picking tractor was made in Georgia in 1963 ЧСН-1, 6/1, 3 А “Saqartvelo”.
Tea picking machine – Tea picking machine, hanger or self-propelled from tea wallpapers. Work on creating a tea picking machine in Georgia began in 1930. Subsequently, the State Design Bureau of Tea, Subtropical and Mountain Machinery set up a group of machines working on different principles, and released their test batches. In 1963, the serial production of the tea picking machine – Chsn-1,6 “Georgia” – began (for its creation the group of authors was awarded the Lenin Prize in 1967); Used for picking delicate tea pods from tea wallpapers, for light formation of tea bushes and for picking Lao-tea. Can work up to 8 ° on slopes and plains. The main nodes of the tea picking machine are the tea picking machine, which has comb-pneumatic working bodies and cutting knives, pneumatic conveyor system, suspension, bunkers, automatic hydraulic steering system and transmission. The tea picker consists of a tea picker, comb, drive mechanism, nozzle, air ducts and elastic corrugated hose. The joint connection with the chassis suspension system of the device ensures the movement of the device in horizontal and vertical plane, as well as tilting sideways. The comb of the apparatus has one movable and two movable cutting arcs. During the operation of the tea-picking machine (the machine runs along the wallpaper) the working bodies of the tea-picking apparatus, which are controlled by a hydraulic drive system, are deepened to the required depth in the bush drill. The elastic clamps of the knives move backwards and forwards to find the most fragile place to break. The pickles are cut between the wooden supports of the real fingers and the elastic bands of the moving fingers, while the rest of the strongly developed tea bags, which are located above the fingers, are cut by cutting knives. Picked tea bags carry an air stream through the air ducts to the drum conveyors, which drop the leaf into the receiving boxes of the receiving hopper. The car is assembled on a self-propelled chassis T-16mm.
The tea-picking machine Cha-900/650 is self-propelled, used for selective picking of tea leaves (leaving inaccessible bushes on the bush), for picking up the massive entry of deaf bushes, for repairing wallpapers, for picking up edge material and for picking Lao tea on the plains. The suspension of the tea picking machine is a three-wheeled chassis. It has a semi-automatic machine that can be installed correctly when working on a slope. Tea picking machines of different sizes (for different rows) of the same construction are mounted on the chassis. Their working bodies are replaceable cutting arcs, which have special elastic guards built into the real fingers. In the process of picking, the elastic guards will deviate from the machine. The device is equipped with a six-section tarabua and two conveyors (main and output). Working bodies are handled by a chassis power take-off shaft. The working bodies of the tea-picking machine will put the necessary measures in the bush. The rubber wings of the tarabua bring the tea bags to the cutting arc. At the top of the arc are selective shafts that rotate when in contact with the Tarabua wing. Attached to the bottom of the cutting arc are capron threaded fingers, which do not allow inaccessible nails in the area of action of the cutting arc. Tarabouti tilts high ducts to deliver selective rollers to the tea picker. The cut tea meets the main and transverse conveyor in the hopper. The productivity of tea picking machines is 0.2 ha / h when the speed is equal to 1 km / h. There are also hand-motorized tea picking machines, they can be petrol-powered and electric-powered, the main components of a petrol-powered tea picking machine are the engine, the power transmission and the picking apparatus. Electric (powered by a generator) The main nodes of a tea picking machine are a generator, an electric motor, a 50 m long cable, a picking machine, and a machine powered by an electronic grid – a microtype electric picking machine, a transformer-converter, 50 m long. The picking device receives energy from an electrical outlet with a transformer that feeds two devices simultaneously. Picking machines have segmental cutting blades. In the process of picking, the worker moves the machine from the surface of the bush to such a level that it collects quality leaves.
