Изобретение относитс к сельскохоз йственному машиностроению, в частности к чаесборочным машинам.FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, tea harvesting machines.

По основному авт. св. № 538686 известен чаесборочный аппарат, содержаш.ий установленное параллельно его продольной оси подаюше-транспортирующее устройство, выполненное в виде смонтированных на шкивах бесконечных контактирующих. между собой элементов, и установленный перед ним механизм дл отделени флешей выполненный в виде звездочек 1.According to the main author. St. No. 538686 is known for the tea-collecting apparatus, which is installed parallel to its longitudinal axis by the feeding-transporting device, made in the form of endless contacting pulleys mounted on the pulleys. between the elements, and the mechanism in front of it for separating flushes made in the form of asterisks 1.

Недостатком известного устройства вл етс мала полнота сбора флешей, вызванна тем, что звездочки аппарата имеют одинаковое число зубьев и враш,аютс с одинаковым числом оборотом, в результате чего между зубь ми звездочек остаютс зазоры , в результате чего часть флешей остаетс несрезанной.A disadvantage of the known device is the small completeness of the collection of flushes, due to the fact that the sprockets of the apparatus have the same number of teeth and vras, they turn with the same number of turns, as a result of which there are gaps between the teeth of the sprockets, resulting in a part of the flushes remaining uncut.

Цель изобретени -т повышение полноты сбора флешей.The purpose of the invention is to increase the completeness of the collection of flash.

Указанна цель достигаетс тем, что количество серповидных встречно-вращаюшихс зубьев режуших звездочек находитс в соотношении 5:6.This goal is achieved by the fact that the number of sickle-shaped counter-rotating teeth of cutting stars is 5: 6.

На фиг. 1 показан предлагаемый аппарат, обший вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - узел I на фиг. 2.FIG. 1 shows the proposed apparatus, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2

Чаесборочный аппарат содержит двигатель 1, центробежный вентил тор 2, клинноременную передачу 3, трансмиссию 4, руко тки 5 и 6, корпус 7, односекционное подающетранспортируюшее устройство 8. Подающе-транспортируюшее устройство 8 состоит из приводного вала 9, соединенного с трансмиссией 4 и корпуса редуктора 10. На валу насажена шестерн 11, св занна со спаренными зубчатыми колесами 12 и 13, на валы 14 и 15 которых насажены ведуш,ие шкивы 16 и 17 бесконечных элементов 18 и 19, соединенных в свою очередь с ведомыми 15 шкивами 20 и 21, на валах 22 и 23 которых насажены звездочки 24 и 25 с округленными зубь ми. Отношение чисел зубьев в каждой паре звездочек находитс в сооношении 5:6. Зубь звездочек заточены как с передней 26, так и в затылочной 27 част х. Подаюше-транспортирующие устройства 8 размешены по дуге корпуса 7, повтор ющей крону чайного куста.Assembly device contains engine 1, centrifugal fan 2, wedge-time transmission 3, transmission 4, handles 5 and 6, housing 7, single-section supplying transport device 8. Delivery-transporting device 8 consists of a drive shaft 9 connected to transmission 4 and gear housing 10. A gear 11 is mounted on the shaft, which is connected to paired gears 12 and 13, on the shafts 14 and 15 of which the leading pulleys 16 and 17 of the endless elements 18 and 19, which in turn are connected with the driven 15 pulleys 20 and 21, are mounted, on shafts 22 and 23 which n sazheny sprockets 24 and 25 with rounded teeth. The ratio of the number of teeth in each pair of stars is in the ratio of 5: 6. The sprocket teeth are sharpened both from the front 26 and in the occipital 27 parts. The conveying devices 8 are placed along the arc of the housing 7, which repeats the crown of the tea plant.

Claims

The operation of the apparatus is as follows. Torque from engine 1 via a wedge-belt drive 3, transmission 4, drive shafts 9 is transmitted to single-section delivery-conveying devices 8 through shafts 9, 14 and 15 to sprockets 24 and 25. The device is installed across the trellis by handles 5 and 6 In the process of moving the apparatus along the tea bars, the sprocket 24 and 25 with rounded teeth manually grip the tea flushes on the surface of the bush, which are fed into the working slot and cut off the tooth parts sharpened on both sides. yev. The cut flushes captured by the endless elements 18 and 19 are transported by rubber elements (rings) in contact on the platform of the housing 7, from where they enter the tea bag of the apparatus using the air flow generated by the fan 2. On the basis of experimental data, it was found that the highest quality collection of tea flushes in height and purity of the cut is obtained when the ratio of the numbers of teeth in each pair of stars 5: 6. The use of a different number of teeth in the tea-collecting apparatus in the ratio of 5: 6 flash separating sprockets ensures complete overlapping of the sprockets, i.e. the gaps between the teeth are eliminated during operation, which results in a complete collection of tea flushes. The teeth of sprockets ground in the front and rear parts provide a clean cut of tea flushes and damage to the crown of the bush is excluded. Formula of the invention Tea-collecting apparatus according to the author. St. No. 538686, due to the fact that, in order to increase the completeness of the collection of flushes, the number of crescent-shaped counter-rotating teeth of the cutting sprockets is 5: 6.
