Изобретение относитс к сельскохоз йственномзг машиностроению, и может быть использовано в конструкци х корнеклубнеуборочных машин.FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in the designs of root-harvesting machines.

По основному авторскому свидетельству № 427667 известен картофелеуборочный 5 комбайн, содержащий подкапывающий лемех , сепарирующий рабочий орган, комкодавитель , состо 1дий из транспортера и установленных над ним двух упругих баллонов , ботвоудалитель, подъемный барабан, ю переборочный стол и бункер. В данном комбайне с целью уменьшени его габаритов и повышени эффективности работы комкодавител , транспортер последнего установлен с огибанием задней части первого по ходу упругого баллона, при этом его 5 рабоча поверхность имеет наклон к горизонту такой, что в передней части угол меньше угла скатывани клубней, а в задней , расположенной за первым баллоном больше 1.20According to the main author's certificate No. 427667, a potato harvester 5 is known, which contains a digging blade, a separating tool, a cofibrator, a 1t of a conveyor and two elastic cylinders mounted above it, a topper, a lifting drum, a bulkhead table and a bunker. In this combine, in order to reduce its size and increase the efficiency of the komkodavitel, the conveyor of the latter is installed with a rounding around the back of the first along the elastic cylinder, while its 5 working surface is inclined to the horizon such that in the front part the angle is less than the angle of tuber rolling, and in the back, located behind the first balloon is greater than 1.20

Недостатками известного устройства вл ютс ограниченна возможность транспортировани массы,св занна со скоростью вращени баллонов-комкодавителей коэффициентом поверхностного трени сепарируемой массы, а также повреждени корнеклубнеплодов , часть которых, не попав под второй комкодавитель, возвращаетс к первому li практически остаетс в указанном промежутке.The disadvantages of the known device are the limited possibility of transporting the mass, related to the speed of rotation of cylinders, the coefficient of surface friction of the separated mass, as well as damage to the root and tuber crops, some of which, not falling under the second group, returns to the first li in this interval.

Кроме того, при остановке рабочих органов , транспортируема масса скапливаетс между первым и вторым комкодавнтел ми и дл продолжени технологическою процесса (включени рабочих органов) необходимо вмешательство тракториста и ручна разгрузка транспортера.In addition, when the working bodies are stopped, the transported mass accumulates between the first and second companions and to continue the technological process (switching on the working bodies), intervention of the tractor driver and manual unloading of the conveyor is necessary.

Цель изобретени - повышение надеж ности работы и снижение повреждаемости корнеклубнеплодов.The purpose of the invention is to increase the reliability of the work and reduce the damage to the root crops.

Поставленна цель достигаетс v.-. -1 i картофелеуборочный комбайн снабжен бесконечным эластичным элементом, охватываюш ,им упругие баллоны комкодавител и имеющим на своей рабочей поверхностп сход щиес его середине, против направлени движени , пальчатые полосы.The goal is achieved v .-. -1 i the potato harvester is equipped with an endless elastic element, encompassing it with the elastic cylinders of the komodavavitel and having on its working surface converging its middle, against the direction of movement, notched stripes.

Claims

FIG. 1 shows a potato harvester scheme; in fig. 2 - arrangement of the cylinders relative to the conveyor. The potato harvester 1 contains a digging blade 2, a separating tool 3, a composer 4, a topper 5, a lifting drum 6, a bulkhead table 7, a bunker 8. Domnodavitel 4 includes two elastic cylinders 9 and 10, a conveyor 11 with a tension shaft 12 and covering the elastic cylinders 9 and 10 are an infinite element 13 with finger stripes 14. The operation of a potato harvester is as follows. Undermined soil with tubers (separated mass), is fed to the separating working body 3 and falls on the conveyor 11 under the cylinder 9. Due to the rounding of the rear part of the cylinder by the conveyor 11, the time to impact on soil clumps increases and their destruction improves. Due to the pressure of the mass of infinity - .., - ".," V, v ,. With the common element 13, the latter is sustainedly gripped and transported at a large angle of inclination to a considerable height with a small length of conveyor 11. Due to the use of the finger stripes 14, the separated mass is further displaced to the center of the spacer 4 and additional destruction of the soil lumps under the second balloon 10. Further The work cycle of the combine is no different from the known. By reducing the speeds of the working bodies or stopping their separated mass is fixed on the conveyor 11 by an endless element 13, which prevents its unloading and eliminates the need for manual disassembly, and takhche losses of roots from damage in the specified interval. The use of the invention allows to increase the reliability of work and reduce the damage to root vegetables. Claims of the invention Potato harvester according to ed. St. No. 427667, characterized in that, in order to increase the reliability of the work and reduce the damage to the root crops, it is equipped with an endless elastic element encompassing the elastic cylinders of the komnodavitel and having on its working surface converging to its middle, against the direction of movement, the tabular bands.
