Description

Изобретение относитс к cenbCKOxoajritcTвенному машиностроению и направлено на усовершенствование устройств, предназначенных дл захвата засоренных толстостебельных и тонкостебельных культур, например , подсолнечника, клещевины, кукурузы.The invention relates to cenbCKOxojitec mechanical engineering and is aimed at improving devices for capturing weedy thick-stemmed and thin-stemming crops, for example, sunflower, castor bean, corn.

Известно устройство дл захвата стебле к уборочным сельхозмашинам, содержащее вращающиес на ос х диски в виде зубчатых колес, располо5кенных в одной-плоскоети , делители и неподвижно закреппенные прутковые стеблеотводы, изогнутые по профилю задних кромок делителей lj .A device for capturing a stalk to an agricultural harvesting machinery is known. It contains rotating disks on the axles in the form of gear wheels located in one flat surface, dividers and fixedly fixed rod stem rods bent along the profile of the rear edges of the dividers lj.

В таких устройствах при работе на засоренных толстостебельных или тонкостебельных культурах боковые грани зубчатых колес наматывают срезанные тонкие растен на оси через щели между кромкой делителей и поверхиостью зубчатых колес, что ведет к деформации делителей, забиванию и остановке зубчатых колес.In such devices, when working on clogged thick-stemmed or thin-stem cultures, the lateral faces of the gear wheels wind the cut off thin vegetation on the axis through the gaps between the edge of the dividers and the surface of the gear wheels, which leads to deformation of the dividers, blockage and stop of gear wheels.

Дл предотвращени наматывани тонких стеблей на оси необходимо сн ть срезанные стебли с поверхности зубчатых ко- To prevent thin stems from coiling on the axis, it is necessary to remove the cut stems from the surface of the toothed teeth.

лес до момента встречи зубьев колес с крокой делител .the forest until the meeting of the teeth of the wheels with a croque divider.

Такой процесс можно обеспечить при наличии нулевого зазора между верхней повер верхностью зубчатых колес и кромкой делител , но практически очень трудно получить нулевой зазор между двум поверхност ми .Such a process can be ensured if there is a zero gap between the upper surface of the gears and the edge of the divider, but it is practically very difficult to obtain a zero gap between the two surfaces.

Цель изобретени - обеспечение возможности использовани устройства при уборке засоренных толстостебельных и гонкостебельных культур.The purpose of the invention is to provide the possibility of using the device when harvesting clogged thick stem and race stalk crops.

Это достигаетс тем, что устройство снабжено дополнительными дисками, установленными свободно посредством осей на верхней поверхности зубчатых колес у задних кромок делителей, причем стеблеотводы размещены под 3y64aTbnviH колесами.This is achieved by the fact that the device is equipped with additional disks mounted loosely by means of axles on the upper surface of the gear wheels at the rear edges of the dividers, moreover, the stem rods are located under the 3y64aTbnviH wheels.

Каждый дополнительный диск расположен так, чтобы его наружна окружность и окружность впадин зубчатого колеса имела общую касательную.Each additional disk is positioned so that its outer circumference and the circumference of the gear troughs have a common tangent.

Claims

To provide a guaranteed zero gap between the gears and the dv scars, the latter are mounted on a spherical support and have plate blades. FIG. 1 shows schematically a device for capturing stems; in fig. 2 same, section A - A in FIG. one.; in fig. 3 node G. The device contains rotary axes x 1 gear copes 2 located in the same plane, depipei 3 fixedly mounted under the toothed wheels, art. 4 branches, having the form of curvilinear rods bent along the profile of the rear edges of dividers, and additional disks 5, mounted on a spherical support 6 and cogged wheels pressed to the upper surface by means of a leaf spring 7. The device works as follows. When advancing the harvester across the field, the stems enter the space with dividers, the tooth m counter-rotating wheels and are cut by the cutting apparatus 8. After cutting, the thick stems, in motion, interact with the edges of the slider and with the pick-off 4. Since during cutting the butt part of the stalks is kept by the cutting apparatus, the rotation of the gears is uniform, the stems tilt in the direction of the machine and, when coming off the teeth, are placed on the header platform. After cutting, the thin stems interact with the edges of the disk. During the interaction of the stems with the discs, the latter begin to rotate in the same direction with the gear wheels and remove or cut off the thin stems from the teeth of the wheels. The lower short part of the stem, cut first with a cutting machine, and then with additional disks, falls down, and the upper long part of the stem loses reliable contact with the teeth of the wheel and is dropped onto a platform in a stream with thick stems. If, however, I remove or cut a thin stalk with a disk from the bottom of the gear wheel, then the lateral faces of the teeth of the wheel will pull the cut thin stalks into the gap between the edge of the divider and the surface of the gear wheels, which will lead to deformation of the dividers and stop the gear wheels. Claim 1. A device for grabbing stalks to agricultural harvesting machines, containing discs in the form of gears, dividers, stem sticks, characterized in that, in order to use the device when harvesting clogged thick-stemmed, as well as thin-stem crops, it is equipped with additional disks 1, installed freely by means of axles on the upper surface of the gear wheels at the rear edges of the dividers, moreover, the stem rods are placed under the gear wheels.

2. Device pop. 1, differing from the fact that each additional disk is positioned so that its outer circumference and the circumference of the cavities of the gear wheel have an oblique tangent.

3. The device according to paragraphs. 1 and 2, different from the fact that the disks are fixed on the axes with spherical supports and provided with springs. Sources of information taken into account in the examination ;; 1. USSR author's certificate N9 20989О, M. Кл.А 01 D 57/00, 1966.
