Vertical windrower dividing device

Abstract

Provided is a vertical windrower dividing device. The vertical windrower dividing device comprises a rack formed by splicing a plurality of brackets, a power transmission mechanism mounted installed on the rack, a straining mechanism and an auxiliary mechanism, wherein a first header bracket and a second header bracket which are mounted on the rack are rotatably installed at a connecting device in the middle of a windrower, and power of a main machine is transmitted to the power transmission mechanism through a middle transmission device and then transmitted to the straining mechanism and the auxiliary mechanism by the power transmission mechanism. According to the vertical windrower dividing device, when branches of oilseed rapes intersect tightly, as the whole machine moves forward, the extrusion force applied on the branches of the oilseed rapes by a second header branch dividing bar and a first header branch dividing bar becomes larger so as to separate the part, wound loosely, of the branches, and the other part, which is not separated, of the branches moves upwards along oblique surfaces of the second header branch dividing bar and the first header branch dividing bar, gradually enters an effective cutting range of a branch division moving cutter, and is cut off; above all, a principle of passive extrusion branch division is made full use of, and the loss ratio caused by active cutting branch division is reduced to a maximum extent.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a crop dividing device for a vertical windrower. Background technique [0002] Rapeseed and other crops are vine-like plants with thick stems, many branches and serious entanglement between the branches. When harvesting, the operation area must be separated from the rapeseed in the adjacent area to be operated, otherwise on the one hand, mutual involvement will cause losses. , On the other hand, it may cause blockage and affect the operation effect, so when harvesting such plants, a grain dividing device should be equipped. [0003] There are two main types of grain dividing devices on existing windrowers: one is a passive grain dividing device, and this type of grain dividing device is purely completed by the squeezing action of the machine on the crops, such as a small rice and wheat windrowing machine.

Problems solved by technology

[0002] Rapeseed and other crops are vine-like plants with thick stems, many branches and serious entanglement between the branches. When harvesting, the operation area must be separated from the rapeseed in the adjacent area to be operated, otherwise on the one hand, mutual involvement will cause losses. , on the other hand, it may cause blockage and affect the operation effect, so when harvesting such plants, a grain dividing device should be equipped

[0003] There are two main types of grain dividing devices on existing windrowers: one is a passive grain dividing device, and this type of grain dividing device is purely completed by the squeezing action of the machine on the crops, such as a small rice and wheat windrowing machine. The obliquely installed triangular grain divider equipped on the outermost side has a better effect on rice, wheat and other crops with few branches and regular planting row spacing, but for rapeseed crops with many branches and irregular spreading row spacing, Difficult to meet the crop distribution requirements;

[0004] Another kind of grain dividing device adopts the installation of a vertical cutting knife for active cutting to separate the crops. This type of grain dividing device has a better effect on the division of crops, but it is easy to forcefully cut off the branches between adjacent crops directly. If it falls on the field, it will cause great damage to crops
