Description

Technical Field

[0001] This utility model belongs to the field of baling machine technology, specifically, it relates to a traction device for a baling machine. Background Technology

[0002] With the rapid development of animal husbandry, the demand for high-quality forage products has been increasing year by year. In order to facilitate the storage and transfer of forage, balers are used to collect and bale pasture or crop straw. During operation, a picking device is used to pick up the straw strips on the ground, and a feeding and pressing device is used to push them into the baling chamber. Under the action of the rollers, the straw strips rotate to form bales.

[0003] In the existing technology, the baler is a non-powered machine that needs to be connected to a tractor through a traction device and is towed by the tractor.

[0004] Chinese utility model patent application number 202320248722.3 discloses a hay baler that is easy to inspect and maintain. In this patent, the hay baler is connected to the tractor via a front-end traction beam. The main problem with this traction beam is that it is located below the drive shaft. When the tractor lifts the baler, the front end of the traction beam is prone to colliding with the drive shaft above, potentially causing deformation. Furthermore, different tractors have different sizes and models, resulting in variations in the position of the suspension nose. In existing traction devices, the spacing and installation position of the suspension components on the suspension beam are fixed, requiring the replacement of different suspension beams to adapt to different tractors, which is very cumbersome. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a traction device for a baler, which adopts an extended and sunken connector and a suspension assembly installed in multiple positions, thus solving the problem that the traction device may collide with the drive shaft during the lifting process, and is also compatible with the suspension connection of tractors of different models and sizes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A traction device for a baler includes a traction beam, a recessed connector is fixed to the front end of the traction beam, a suspension beam is installed on the recessed connector via a bidirectional connector, and a suspension assembly is installed at each end of the suspension beam.

[0008] The sunken connector includes a fixed sleeve, a sunken inclined tube, and a sunken crossbeam arranged in sequence. The fixed sleeve is fixed to the front end of the traction beam. The sunken inclined tube is inclined downwards. The upper end of the sunken inclined tube is fixed to the fixed sleeve. The lower end of the sunken inclined tube is fixed to the sunken crossbeam. One end of the bidirectional connector is fixedly installed on the sunken crossbeam, and the other end of the bidirectional connector is fixedly installed on the suspension beam.

[0009] The following are further optimizations of the above technical solution by this utility model:

[0010] The suspension assembly includes a first hook, a second hook, and a third hook arranged sequentially from the outside to the inside. Each of the first, second, and third hooks has at least one pair of pin holes. The first hook is fixed to the end of the suspension beam, and the second and third hooks are fixed to the side wall of the suspension beam away from the traction beam.

[0011] Further optimization: The bidirectional connector includes a first connecting part and a second connecting part. One end of the first connecting part is fixedly installed on the sinking crossbeam by fastening bolts. The other end of the first connecting part is hinged to the second connecting part by a hinge shaft. A fixed column is rotatably installed on the second connecting part. The fixed column is perpendicular to the hinge shaft and is fixedly installed in the middle of the suspension beam.

[0012] Further optimization: The front end of the traction beam is provided with a square tube, and a fixing sleeve is fitted and fixed on the square tube. A fixing platform is provided on the rear side of the square tube. A horizontal tube is fixed at the rear end of the traction beam, and a corner seat is fixed at each end of the horizontal tube.

[0013] Further optimization: A sleeve is provided on each of the two side walls of the traction beam, and a foot is inserted into each sleeve. The upper end of each foot is fixed to the sleeve by a pin.

[0014] The present invention adopts the above-mentioned technical solution and has the following beneficial effects: The present invention adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. The setting of the sunken connecting part increases the distance between the front end of the traction beam and the drive shaft, avoids the traction beam from colliding with the drive shaft during the lifting process of the baler, improves the safety of the traction device and ensures the continuous use of the drive shaft.

[0015] The multi-position suspension assembly includes a first hanger nose, a second hanger nose, and a third hanger nose. The first hanger nose, the second hanger nose, and the third hanger nose form multiple holes for fixing the hanger noses on the tractor. The hanger noses on tractors of different types and sizes are inserted into different holes for fixed connection without the need to replace the suspension beam. This makes the present invention adaptable to different types and sizes of suspension connections, thereby improving the applicability of the present invention.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description
