Description

A double-sided drive crushing mechanism and a baler Technical Field

[0001] This application relates to the field of baling machine technology, and in particular to a double-sided drive crushing mechanism and a baling machine. Background Technology

[0002] Currently, most commercially available forage balers use the following transmission method: the tractor's PTO power is first transmitted to the gearbox via a drive shaft, and then the gearbox splits the power into two outputs. One output is transmitted to the baler at the rear, and the other is transmitted from the right side to the cutter roller on the first shaft, and then through the cutter roller to the auger pusher on the second shaft.

[0003] However, due to the harsh operating environment of balers and their inherent structural design, the cantilever of the first shaft is quite long, and the second shaft's auger pusher with its fan blades requires significant power. This results in the first shaft bearing substantial torque and load during operation, potentially leading to problems such as cracking of the crushing mechanism housing and bearing damage. Furthermore, this series transmission configuration can cause unstable power output, affecting the overall performance and reliability of the equipment. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a dual-sided transmission crushing mechanism and a baler to solve the problems that the transmission form of existing balers is prone to causing unstable power output and cracking of the crushing mechanism housing.

[0005] According to a first aspect of the present invention, a dual-sided transmission crushing mechanism is provided, wherein the dual-sided transmission crushing mechanism includes: a first gearbox, provided with a PTO power input shaft, the first gearbox being connected to the baler body via a first drive shaft; a second gearbox, connected to the first gearbox via a second drive shaft, the second gearbox having a third drive shaft and a fourth drive shaft connected to its two sides respectively; a swivel roller, connected to the third drive shaft; and a spiral pusher, connected to the fourth drive shaft.

[0006] Preferably, the third drive shaft and the fourth drive shaft are respectively disposed on opposite sides of the second gearbox, and the third drive shaft and the fourth drive shaft are coaxial.

[0007] Preferably, the third drive shaft is connected to the end of the swivel roller via a first drive unit, and a first bearing housing assembly is provided between the third drive shaft and the first drive unit.

[0008] Preferably, the first transmission unit includes: a first pulley connected to the first bearing housing assembly via a shaft; a cutter roller pulley mounted on the end of the cutter roller; and a first belt, wherein the first pulley and the cutter roller pulley are connected via the first belt for transmission.

[0009] Preferably, the fourth drive shaft is connected to the end of the spiral pusher via a second drive unit, the second drive unit and the first drive unit are respectively located on both sides of the baler, and a second bearing housing assembly is provided between the fourth drive shaft and the second drive unit.

[0010] Preferably, the second transmission unit includes: a second pulley connected to the second bearing housing assembly via a shaft; a spiral pusher pulley mounted on the end of the spiral pusher; and a second belt, wherein the second pulley and the spiral pusher pulley are connected via the second belt drive.

[0011] Preferably, the dual-side transmission crushing mechanism further includes a traction beam, which is installed on the baler body, and the first gearbox is installed on the traction beam.

[0012] Preferably, the traction beam includes multiple support beams, the first ends of the multiple support beams are connected to the baler body, and the second ends of the multiple support beams are respectively connected to both sides of the first gearbox.

[0013] Preferably, the first gearbox is located on the side of the second gearbox away from the baler body, and the first drive shaft is located above the second drive shaft.

[0014] According to a second aspect of the present invention, a baling machine is provided, wherein the baling machine includes a baling machine body and a double-sided transmission crushing mechanism as described above, the double-sided transmission crushing mechanism being installed on the baling machine body.

[0015] This utility model discloses a dual-side transmission crushing mechanism and baler. The first gearbox is equipped with a PTO power input shaft, allowing the tractor's power to be input first. The first gearbox is connected to the baler body via a first drive shaft, transmitting a portion of the power to the baler body. The second gearbox is connected to the first gearbox via a second drive shaft, allowing the remaining power from the first gearbox to be transmitted to the second gearbox. A third and fourth drive shaft are connected to both sides of the second gearbox. The swivel roller is connected to the third drive shaft, and the auger pusher is connected to the fourth drive shaft. This configuration allows the power from the second gearbox to be transmitted to the swivel roller and the auger pusher respectively. By changing the transmission method of the swivel roller and the auger pusher from series to parallel, the length of the swivel roller shaft and cantilever can be effectively shortened. This improvement not only extends the service life of the swivel roller but also prevents cracking of the crushing mechanism housing. Furthermore, by increasing the number of gearboxes, the load is reasonably distributed, thereby increasing the service life of the gearboxes and significantly enhancing the smoothness of the power transmission process. This effectively solves the problems of unstable power output and cracking of the crushing mechanism housing caused by the transmission method of existing balers.

[0030] As shown in Figures 1 and 2, a dual-drive crushing mechanism is provided according to a first aspect of the present invention. The dual-drive crushing mechanism includes a first gearbox 1, a second gearbox 2, a swivel roller 3, and a spiral pusher 4.

[0031] In the following description, the specific structure of the above-mentioned components of the double-sided drive crushing mechanism and the connection relationship of the above-mentioned components will be described in detail with reference to Figures 1 and 2.

[0032] As shown in Figures 1 and 2, in this embodiment, the first gearbox 1 may be equipped with a PTO power input shaft 11, allowing power to be input to the first gearbox 1 first. The first gearbox 1 can be connected to the baler body 5 via a first drive shaft 100, thereby transmitting a portion of the power to the baler body 5. The second gearbox 2 can be connected to the first gearbox 1 via a second drive shaft 200, allowing another portion of the power from the first gearbox 1 to be transmitted to the second gearbox 2. A third drive shaft 300 and a fourth drive shaft 400 can be connected to both sides of the second gearbox 2, respectively. The swivel roller 3 can be connected to the third drive shaft 300, and the spiral pusher 4 can be connected to the fourth drive shaft 400. With this configuration, the power of the second gearbox 2 can be transmitted to the swivel roller 3 and the spiral pusher 4, respectively. By changing the transmission method of the swivel roller 3 and the spiral pusher 4 to parallel, the length of the swivel roller 3 shaft head and cantilever can be effectively shortened, thereby preventing cracking of the housing of the double-sided transmission crushing mechanism. In addition, by increasing the number of gearboxes, the load can be distributed more reasonably, thereby significantly improving the smoothness of the power transmission process.

[0033] Preferably, as shown in Figures 1 and 2, in this embodiment, the dual-side transmission crushing mechanism may further include a traction beam 10, which can be installed on the baler body 5, and the first gearbox 1 can be installed on the traction beam 10. Specifically, the traction beam 10 may include multiple support beams 110 (which may be the two shown in the embodiment), and the multiple support beams 110 may be respectively arranged on both sides of the first gearbox 1. One end of the traction beam 10 can be fixedly installed to the frame of the baler body 5 by bolts, and the other end of the traction beam 10 can be installed to the housing of the first gearbox 1 by bolts.

[0034] Further, preferably, as shown in Figure 1, in this embodiment, the first gearbox 1 and the second gearbox 2 can be approximately rectangular in shape. The support beam 110 may include a longitudinal beam and a traction frame. The traction frame can be obliquely connected to the longitudinal beam, so that a bend can be formed in the middle of the support beam 110, thereby allowing the support beams 110 located on both sides of the first gearbox 1 to converge towards the center. The two support beams 110 can be respectively connected to two opposite sides of the first gearbox 1, thereby fixing the first gearbox 1. The PTO power input shaft 11 can be located on the side of the first gearbox 1 away from the baler body 5. The PTO power input shaft 11 can be connected to the PTO shaft drive of the tractor, thereby transmitting power to the first gearbox 1.

[0035] Preferably, as shown in Figures 1 and 2, in this embodiment, the first gearbox 1 can be disposed on the side of the second gearbox 2 away from the baler body 5. A gap is provided between the first gearbox 1 and the second gearbox 2. The first drive shaft 100 and the second drive shaft 200 can be connected to the side of the first gearbox 1 near the baler body 5. The first drive shaft 100 can be disposed above the second drive shaft 200, making it easy to connect the first drive shaft 100 to the clutch of the baler body 5, while the second drive shaft 200 can connect the first gearbox 1 and the second gearbox 2, thereby avoiding interference between the first drive shaft 100 and the second drive shaft 200. The first drive shaft 100 and the second drive shaft 200 can be keyed to the first gearbox 1.

[0036] Preferably, as shown in Figures 1 and 2, in this embodiment, the third drive shaft 300 and the fourth drive shaft 400 can be connected to opposite sides of the second gearbox 2, respectively, while the second drive shaft 200 can be connected to the side of the second gearbox 2 closest to the first gearbox 1. The third drive shaft 300 and the fourth drive shaft 400 can be coaxially arranged, and the second drive shaft 200 can be perpendicular to the axes of the third drive shaft 300 and the fourth drive shaft 400.

[0037] Preferably, as shown in Figures 1 and 2, in this embodiment, the swivel roller 3 and the spiral pusher 4 can be arranged parallel to the axes of the third drive shaft 300 and the fourth drive shaft 400. The third drive shaft 300 can be connected to the end of the swivel roller 3 via a first drive unit 6, thereby transmitting power to the swivel roller 3. A first bearing housing assembly 7 can be provided between the third drive shaft 300 and the first drive unit 6. The fourth drive shaft 400 can be connected to the end of the spiral pusher 4 via a second drive unit 8, thereby transmitting power to the spiral pusher 4. A second bearing housing assembly 9 can be provided between the fourth drive shaft 400 and the second drive unit 8. The first drive unit 6 and the second drive unit 8 can be respectively located on both sides of the baler to allow sufficient installation space.

[0038] In this embodiment, since the swivel roller 3 and the spiral pusher 4 are connected in parallel, the load can be reasonably distributed. The swivel roller 3 and the spiral pusher 4 can be respectively provided with a first bearing housing assembly 7 and a second bearing housing assembly 9, thereby avoiding damage to the bearings due to excessive force.

[0039] Further, preferably, as shown in Figures 1 and 2, in this embodiment, the first transmission unit 6 may include a first pulley 61, a cutter roller pulley 62, and a first belt 63. The first pulley 61 can be connected to the first bearing housing assembly 7 via a shaft drive, allowing the power of the third transmission shaft 300 to be transmitted to the first pulley 61 through the first bearing housing. The cutter roller pulley 62 can be mounted on the end of the cutter roller 3. The cutter roller pulley 62 can be connected to the first pulley 61 via the first belt 63, thereby transmitting the power of the second gearbox 2 to the cutter roller 3.

[0040] Additionally, preferably, as shown in Figures 1 and 2, in this embodiment, the second transmission unit 8 may include a second pulley 81, a spiral pusher pulley 82, and a second belt 83. The second pulley 81 can be connected to the second bearing housing assembly 9 via a shaft drive, allowing power from the fourth transmission shaft 400 to be transmitted to the second pulley 81 through the second bearing housing. The spiral pusher pulley 82 can be mounted on the end of the spiral pusher 4. The spiral pusher pulley 82 can be connected to the second pulley 81 via the second belt 83, thereby transmitting power from the second gearbox 2 to the spiral pusher 4.

[0041] Furthermore, as shown in Figures 1 and 2, a baling machine is provided according to a second aspect of the present invention. The baling machine includes a baling machine body 5 and a double-sided transmission crushing mechanism as described above, wherein the double-sided transmission crushing mechanism is installed on the baling machine body 5.

[0042] During use, the baler can be connected to a tractor via transmission. The tractor's power is transmitted to the first gearbox 1 via the PTO power input shaft 11. The first gearbox 1 transmits a portion of the power to the baler body 5 via the first drive shaft 100, and another portion of the power to the second gearbox 2 via the second drive shaft 200. A third drive shaft 300 and a fourth drive shaft 400 are respectively provided on both sides of the second gearbox 2. A portion of the power from the second gearbox 2 is transmitted to the swivel roller 3 via the third drive shaft 300, and the other portion of the power is transmitted to the auger pusher 4 via the fourth drive shaft 400. This configuration allows the transmission of the swivel roller 3 and the auger pusher 4 to be parallel, thereby effectively shortening the length of the swivel roller 3 shaft head and cantilever, thus preventing cracking of the housing of the dual-sided transmission crushing mechanism. Furthermore, the presence of the first gearbox 1 and the second gearbox 2 allows for reasonable load distribution, significantly improving the smoothness of the power transmission process.
