A conveying device for a crawler self-propelled square bale baler

Abstract

A conveying device used for a caterpillar self-propelledpress-baler for square bales of grass belongs to the technical field of pasture harvesting and straw post-treatment, and comprises a trough body, a chain harrow mechanism, a transmission wheel and a chain harrow tightening mechanism, wherein the transmission wheel is sequentially in transmission connection with the chain harrow mechanism and the chain harrow tightening mechanism which are arranged in the trough body. The conveying device is characterized in that the trough body comprises a front end feed opening communicated with a picking up table in front of the press-baler, and a back end discharge opening communicated with a baling device behind the press-baler; the back end discharge opening is lower than the front end feed opening; a first rectangular pipe is horizontally arranged in the front at the bottom of the trough body; a fork-shaped downward oil cylinder seat is arranged on the first rectangular pipe. The conveying device not only can be connected fast with the picking up table, but also can lift the picking up table by arranging a rotating shaft capable of swinging up and down at the upper end of the conveying device; and straw can be conveyed faster and thrown uniformly.

Description

[0001] A conveying device for a crawler self-propelled square bale baler technical field [0002] The invention relates to the technical field of forage harvesting and straw post-processing, in particular to a conveying device for a crawler self-propelled square bale baler. Background technique [0003] The existing types of balers are basically traction balers pulled by tractors. After matching, the shortcomings of long models, inconvenient turning, poor passability of paddy fields, and unclear picking up of fields and feet are not only difficult to adapt to the southern middle school. Small field operations are not suitable for operations in areas with poor road conditions such as mountains and hills, and are also limited by supporting tractors. The cost of long-distance transfer is too high to maintain.

[0003] The existing types of balers are basically traction balers pulled by tractors. After matching, the shortcomings of long models, inconvenient turning, poor passability of paddy fields, and unclear picking up of fields and feet are not only difficult to adapt to the southern middle school. Small field operations are not suitable for operations in areas with poor road conditions such as mountains and hills, and are also limited by supporting tractors. The cost of long-distance transfer is too high to maintain. The wheeled wheat combine harvester was restructured into a wheeled self-propelled baler, but due to the structural limitations of the wheeled wheat combine harvester, the defects such as long front and rear dimensions, poor paddy field passability, and long-distance transportation difficulties have not been overcome. It has been fully solved, especially because the intermediate conveying device connecting the picking table and the feeding and bundling part still adopts the traditional intermediate conveying structure of the combine harvester, its linear speed is low, the grass feeding port is small, and the throwing direction is different from that of the bundling working parts. The feeding direction does not match and other defects can easily cause the feeding inlet to be blocked, especially when the whole straw left after the combine harvester is half-fed into the bundle, and the uneven transportation will also cause the piston to compress the whole straw. The resulting vibration will seriously affect the stability and reliability of the machine
