Extrusion bundling device of automatic straw bundling machine

Abstract

The invention relates to the technical field of agricultural equipment, and discloses an extrusion bundling device of an automatic straw bundling machine. The device comprises a machine shell; a pushshovel is arranged on the left side of the machine shell; a ratchet wheel conveyor belt is arranged on the right side of the push shovel; a double-shaft crusher is arranged on the right side of the ratchet wheel conveyor belt; two extrusion mounting bases are oppositely arranged on the lower right portion of the double-shaft crusher; belt covering wheels are arranged in the extrusion mounting bases; and bundling belts are wound around the outer portions of the belt covering wheels. According to the extrusion bundling device of the automatic straw bundling machine, in a compression block-forming process, bundling needle heads are located on the surface of a straw block, meanwhile, telescopic needles stretch out to push the bundling needle heads to get close to each other, belt pressing wheels and the belt covering wheels are matched for belt feeding, and the bundling belts are tied to the outer circle of the straw block, so that bundling is completed while straw is compressed, the timerequired for bundling the single straw block is effectively shortened; and the bundling needle heads move linearly along with the telescopic needles and bundle the straw block along the surface of thestraw block, so that relative abrasion and collision are less, and the service life is longer.

Description

Technical field [0001] The present invention relates to the technical field of agricultural equipment, in particular a squeezing bundle of straw automatic baler. Background technique [0002] The straw baler is a crushing inside the device, and the compression device first extruded the collected straw together to form a cylinder or square grass block that is easy to transport, and then secures the bundle belt outside it externally. [0003] Nowadays, the raw straw baler generally puts the straw to be square, which is convenient for compression, high efficiency, processing environmental protection, and directly incinerate compared to rural straws, it is given to the feed processing plant, which utilizes higher value but existing automatic play After the ferrier is compressed, the bundle needle to bundle with the arms, which not only needs to separate the compression and bundling process, but also add additional robotic arm, and the arms should be pair of grass, very easy Damage is...

AI Technical Summary

Problems solved by technology

[0003] The more mature straw balers generally compress the straw into a square shape, which is convenient for stacking and transporting, with high efficiency and environmental protection. Compared with the direct incineration of rural straw, it is sent to the feed processing plant, which has higher utilization value, but the existing automatic baler After the baler is compressed, the curved arm baling needle is used to bypass the grass block for baling. This baling method not only needs to separate the compression and baling process, but also adds an additional mechanical arm, and the curved arm baling needle is facing the grass block, which is very easy Damage caused by accidents such as collisions during work, shorter lifespan than other components, frequent replacement and maintenance
