Description

Technical Field

[0001] This utility model relates to the field of round bale balers, and in particular to a split-type, easily replaceable pressure roller for round bale balers. Background Technology

[0002] Currently, the working principle of round straw balers is that the picking mechanism picks up the straw and puts it into the forced feeding chamber. The straw is then fed into the bale chamber through the feeding teeth on the forced feeding shaft for compression and shaping, and finally wrapped with a net to produce the bale.

[0003] However, as the machine is used for longer periods, the bale press rollers in the bale bins will wear out and require repair or even replacement, or the bearings may be damaged due to wear and deformation. However, during the repair and replacement process, since the bale press rollers of existing products on the market are all welded as a whole, disassembly often requires disassembling the entire machine, which is time-consuming and labor-intensive. Even for relatively well-designed round balers, disassembly can be performed without disassembling the entire machine, but the bale press rollers with integrated welded structures often need to be replaced as a whole after local wear or bearing failure and wear of the shaft head. This increases the cost of use and downtime, wastes resources and causes direct economic losses. Summary of the Invention

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] To achieve the above objectives, the first aspect of this utility model proposes a split-type, easily replaceable pressing roller for a round baler, comprising: a drive shaft, an outer shaft seat, and an inner shaft seat. The outer shaft seat and the inner shaft seat are arranged opposite to each other, and bearings are provided inside the outer shaft seat and the inner shaft seat. The drive shaft passes through the outer shaft seat, the bearings, and the inner shaft seat. A drive sprocket is provided at one end of the drive shaft extending out of the outer shaft seat, and the other end of the drive shaft is connected to a roller (a hollow roller with a spline groove inside).

[0006] As an improvement, the number of bearings is two.

[0007] As an improvement, the outer side of the transmission sprocket is provided with a locking plate and a locking nut, which are fixed to the transmission shaft.

[0008] As an improvement, a bolt connection is provided between the outer shaft seat and the inner shaft seat.

[0009] As an improvement, the drive shaft and rollers are splined together.

[0010] Beneficial effects

[0011] This structure, in conjunction with the split pressing roller structure of the round baler, allows for independent maintenance and replacement of parts on the machine. This provides greater flexibility during maintenance and replacement, eliminating the need for extensive disassembly by specialized personnel, and preserving the integrity of the machine. Furthermore, the interchangeable transmission components reduce operating costs and extend the overall machine lifespan. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following description, in conjunction with the accompanying drawings, describes the modular, easily replaceable compression rollers of the round baler according to an embodiment of the present invention.

[0020] like Figure 1-3 As shown, the present invention provides a split-type, easily replaceable pressing roller for a round baler, including a drive shaft, an outer shaft seat, and an inner shaft seat. The outer shaft seat and the inner shaft seat are arranged opposite to each other, and bearings are provided in the outer shaft seat and the inner shaft seat. The drive shaft passes through the outer shaft seat, the bearings, and the inner shaft seat. A drive sprocket is provided at one end of the drive shaft extending out of the outer shaft seat, and the other end of the drive shaft is connected to the roller.

[0021] In this embodiment, there are two bearings, which are respectively installed in the outer bearing seat and the inner bearing seat. This can effectively support the rotation of the transmission shaft, reduce frictional resistance, and improve transmission efficiency and service life.

[0022] The drive sprocket is secured to the drive shaft with a locking plate and a locking nut on its outer side. This structural design ensures the drive sprocket is firmly mounted on the drive shaft, preventing loosening or displacement during operation and guaranteeing the stability and reliability of power transmission. During installation, first place the drive sprocket onto the drive shaft, then install the locking plate and locking nut in sequence. Tightening the locking nut firmly presses the locking plate against the sprocket, achieving reliable sprocket fixation.

[0023] The outer and inner shaft seats are connected by bolts. This bolted connection allows for easy assembly and disassembly of the outer and inner shaft seats. When it is necessary to replace the rollers or maintain components such as bearings, simply unscrewing the bolts allows the outer and inner shaft seats to be separated, making the operation simple and quick and greatly improving maintenance efficiency.

[0024] The drive shaft and roller are connected by a spline connection. The spline connection offers advantages such as high torque transmission, high centering accuracy, and good guiding properties, ensuring reliable power transmission between the drive shaft and roller, while also facilitating roller installation and removal. When roller replacement is required, it can be easily slid out along the spline axis, eliminating the need for complex disassembly operations, reducing labor intensity, and shortening replacement time.

[0025] The working principle of this invention is as follows: Power is transmitted to the drive shaft through the transmission sprocket. The drive shaft, supported by bearings, drives the roller to rotate, thereby realizing the pressing operation of the material. When the roller needs to be replaced due to wear or other reasons, first unscrew the bolts between the outer and inner shaft seats to separate them. Then, slide the roller out along the spline axis. After replacing the roller with a new one, connect and fix the outer and inner shaft seats with bolts.

[0026] In summary, the modular, easily replaceable compression roller of the round baler of the present invention, through its modular structural design, connects the roller to the drive shaft via a spline and the outer and inner shaft seats via bolts, making roller replacement simple and quick, greatly improving the efficiency and maintenance convenience of the round baler, and has significant economic benefits and practical value.
