Description

Technical Field

[0001] The utility model relates to an adaptive density adjustment device for a square baler, belonging to the technical field of agricultural and animal husbandry machinery. Background Art

[0002] The adaptive density adjustment device is a key component of a baler. Its primary function is to apply uniform and stable pressure to the material as it compresses grass and other materials into a dense, regular shape. This reduces the chance of loose bales while ensuring uniform density and a regular bale shape, facilitating bale loading and saving transportation effort. Traditional density adjustment devices for square balers use a single set of springs to apply pressure to the bale. This spring can easily deform during operation, resulting in uneven tension and, consequently, uneven density and irregular bale shape, making loading difficult. While hydraulic balers can address the issue of unstable pressure, they are complex and prone to failure. Furthermore, hydraulic components present the risk of oil leakage and forage contamination. Therefore, there is a pressing need for a density adjustment device for square balers that can adaptively adjust the direction of tension to achieve uniform density and regular shape, while also being simple to manufacture, operate, and maintain. Summary of the Invention

[0003] The utility model is realized through the following technical solutions:

[0004] An adaptive density adjustment device for a square baler is primarily composed of a crank screw, an adaptive density adjustment unit, a lower crossbeam of the baling chamber, a baling chamber, and an upper crossbeam of the baling chamber. Two sets of adaptive density adjustment units are connected to the left and right ends of the upper and lower crossbeams of the baling chamber, respectively. The upper and lower crossbeams of the baling chamber are mounted at the upper and lower ends of corresponding positions in the baling chamber, respectively. The crank screw passes through the upper crossbeam of the baling chamber and is threadedly connected to the adjustment nut in the adaptive density adjustment unit. During use, rotating the crank screw adjusts the tension of the pressure spring in the adaptive density adjustment unit. The pressure spring drives the baling chamber to operate, applying pressure to the material. When adjusting the pressure, the adjustment nut rotates and adjusts in the direction of the force applied to the entire device, thereby achieving adaptive pressure adjustment during the baling process.

[0005] The utility model connects a baling chamber to a baler, and during installation, a square baler is connected to the baling chamber using an adaptive density adjustment device. When the compressed material is pushed out of the baler and enters the baling chamber, the baling chamber tends to deform when the material rebounds. At this time, the pressure spring in the adaptive density adjustment unit with compression force set is deformed, guiding the baling chamber to work and transmitting the pressure to the baled material, thereby achieving the technical requirements of adaptively adjusting the pulling direction and shaping the bale.

[0006] The advantages of the utility model are: the baler equipped with the adaptive density adjustment device for square balers has a stable bale density, uses two sets of springs to provide pressure, has a large density adjustment range and the adjusting nut can be rotated, which can achieve multi-angle adjustment while also providing stable pressure, regular bale shape, high efficiency, low failure rate, stable operation, and can meet the technical requirements of convenient bale loading and saving transportation capacity.
