Description

Изобретение относитс к сельскому хоз йству и предназначено дл срезани высушенных табачных листьев со стебл после уборки и сушки табака целыми растени ми ,,The invention relates to agriculture and is intended to cut dried tobacco leaves from a stem after harvesting and drying tobacco with whole plants.

Известен листоотделительный аппарат, который содержит листоотделительные нОжи расположенные на шпиндельной головке, выполненной ь виде пустотелой оси, и протаскивающие валики.A leaf-separating apparatus is known, which contains leaf-separating knives located on the spindle head, made in the form of a hollow axis, and dragging rollers.

Отделение листьев происходит при подаче стебл протаскивающими валиками и одновременном вращении ножей вокруг стебл со скольжением по, его псжерхности.Leaves are separated when the stem is fed by pulling rollers and at the same time rotating the knives around the stem with sliding along its surface.

В таких аппаратам ножи вместе с листь ми срезают бугорки стеблей, на которых расположены листь , частично кору, а в некоторых случа х и верхушки стеблей, что снижает качество отделени листьев, так как более влажные частицы стеблей, попа- да к менее влажным листь м, вызывают гнездовое плесневение сырь , а срезание верхушек стеблей, кроме того, ведет к .уменьшению оличества неотделенных лисгь ев .In such apparatuses, knives, along with leaves, cut off the tubercles of the stems on which the leaves are located, partially the bark, and in some cases the tops of the stems, which reduces the quality of leaf separation, since more humid particles of the stems fall to less moist leaves. , cause nesting molding of raw materials, and cutting the tops of the stems, in addition, leads to a reduction in the number of unseparated leaves.

Недостатком таких аппаратов вл етс также то, что дл введени очередного табачного растени в аппарат необходимо останавливать его работу.A disadvantage of such apparatuses is also the fact that in order to introduce the next tobacco plant into the apparatus it is necessary to stop its operation.

Цель изобрете1::1 - повышение качества отделени:: листьев и создание условий дл введени очередного табачного растени в аппарат без остановки последнего.The purpose of the invention: 1 :: 1 is to improve the quality of the separation of: leaves and create conditions for introducing another tobacco plant into the apparatus without stopping the latter.

Дл этого ножи укреплены на копирах, которые выполнены раздвижными, а лезвие ножа расположено вдоль оси стебл .To do this, the knives are fixed on the copiers, which are made sliding, and the blade of the knife is located along the axis of the stem.

Введение очередного растени в рабочий орган без остгчовки работы аппарата осуществл етс подшипниковым механизмом посредством отрезков гибких тросов, соединенных с копирами через шестррни-барабаны .The introduction of the next plant into the working body without ostgchki operation of the apparatus is carried out by the bearing mechanism by means of segments of flexible cables connected to the copiers through gears and drums.

На фиг. 1 схематично изображен предлагаемый аппарат дл срезани листьев со стеблей табака, продольныйразрез; на фиг. 2 - то же, разрез А-А на фиг. 1,FIG. Figure 1 shows schematically the proposed apparatus for cutting leaves from tobacco stalks, longitudinal section; in fig. 2 is the same, section A-A in FIG. one,

Claims

The device consists of a pair of dragging rollers 1, fixedly out of the fixed hollow axis 2, on which. in two bearings 3, the body-pulley 4 is rotated with a disk 5 attached to it. In the latter, copiers 6 with knives 7 are placed. Each copier is connected to gear 8, which is integral with the drum, which is wound with a flexible cable 9, a copier with an inner ring of the bearing 10 that is attached to the copier. Under the action of the springs 11, the copiers always tend to close position. They are opened by a U-shaped handle 12, which simultaneously keeps the outer ring of the bearing Yu from turning. The device works as follows. By the movement of the U-shaped handle 12 from Dnfn.n.nvivt I I -vxvy a -m v pj l v ', the support 10 is shifted along the directional keys to the extreme right position. At the same time, the copiers are moved apart due to their connection with the bearing 10 through gears-drums 8 and flexible cables 9. This allows the tobacco plant to be inserted into the machine by the front through the hollow axis 2 before meeting the pulling rollers 1. At the moment of starting the pulling Weaving 12 is released, which causes the closing of the copiers 6 under the action of the springs 11 before meeting the surface of the stem. The separation of the leaves occurs as a result of the translational movement of the stem, carried out by pulling rollers, and the rotation of the knives around the stem. Claim 1. An apparatus for cutting leaves from tobacco stalks, including knives, which are located on leaf sprigs, located on a spindle head, made in the form of a hollow axis, and pulling rollers, characterized in that, in order to cut leaves from a stem, knives are installed on copiers.

2. The apparatus according to claim 1, dt, and h aa y and so that, for the purpose of input (. Into the apparatus, - copiers are made extensible.

3. The device according to claim 1 is also distinguished by the fact that the blade of the knife is located along the axis of the stem.
