Abstract
Description
Technical Field
[0001] The invention 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 an important working part of the baler. Its main function is to apply uniform and stable pressure to the material when the baler presses the grass and other materials into a high-density and regular shape, while reducing the loose bale rate to ensure that the density of the bale is uniform and the shape of the bale is regular, thereby facilitating the loading of the bale and saving transportation capacity. The density adjustment device for the traditional square baler uses a single set of pressure springs to apply pressure to the bale. The spring is prone to deformation during operation, resulting in uneven tension of the pressure spring, uneven density of the pressed bale, irregular shape of the bale, and difficulty in loading the bale. Although hydraulic baling can solve the problem of unstable pressure, it has a complex structure and a high failure rate, and there is a risk of oil leakage and contamination of the grass in the hydraulic components. Therefore, the market is in urgent need of a density adjustment device for square balers that can adaptively adjust the direction of tension to make the bale density uniform and regular in shape, and has a simple structure and is easy to manufacture, operate, and maintain. Summary of the invention
[0003] The present invention is achieved through the following technical solutions:
[0004] An adaptive density adjustment device for a square baler is mainly composed of a crank screw, an adaptive density adjustment unit, a lower crossbeam of a baling chamber, a baling chamber, an upper crossbeam of a baling chamber, and the like. Two sets of adaptive density adjustment units are respectively connected to the left and right ends of the upper crossbeam of the baling chamber and the lower crossbeam of the baling chamber, and the upper crossbeam of the baling chamber and the lower crossbeam of the baling chamber are respectively installed at the upper and lower ends of the corresponding positions of the baling chamber. 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. When in use, the crank screw is rotated to adjust the tension of the pressure spring in the adaptive density adjustment unit. The pressure spring drives the baling chamber to work and exerts pressure on the material. When adjusting the pressure, the adjustment nut will rotate and adjust along with the force direction of the entire device, thereby realizing adaptive adjustment of the pressure during the baling process.
[0005] The present invention connects the baling chamber to the baler, and during installation, the 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 the 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 bale shaping.
[0006] The advantages of the present invention 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 rotate, which can achieve multi-angle adjustment while also providing stable pressure, has a regular bale shape, high efficiency, low failure rate, and stable operation, and can meet the technical requirements of convenient bale loading and saving transportation capacity.
