Description

Technical Field

[0001] The present application relates to the technical field of balers, and in particular to a double-sided transmission shredding mechanism and a baler. Background Art

[0002] At present, the common forage square hay balers on the market generally adopt the following transmission method: the PTO power of the tractor is first transmitted to the gearbox through the transmission shaft, and then the gearbox divides the power into two outputs. One is transmitted backward to the baler, and the other is transmitted from the right side to the swinging roller of the first axis, and then transmitted to the second axis screw pusher through the swinging roller.

[0003] However, due to the harsh working environment of the baler and the influence of its own structural design, the cantilever of one axis of the baler is long, and the power required by the two-axis screw pusher with fan blade is relatively large. As a result, in the actual working process, one axis will be subjected to a large torque and load, which may easily cause problems such as cracking of the crushing mechanism shell and bearing damage. In addition, this series transmission form is prone to unstable power output, which will affect the overall performance and reliability of the equipment. Summary of the invention

[0004] In view of this, the purpose of the present application is to provide a double-sided transmission shredding mechanism and a baler, so as to solve the problem that the transmission form of the existing baler easily leads to unstable power output and cracking of the shredding mechanism shell.

[0005] According to a first aspect of the present invention, a double-sided transmission shredding mechanism is provided, wherein the double-sided transmission shredding mechanism comprises: a first gearbox, provided with a PTO power input shaft, the first gearbox being transmission-connected to the baler body via a first transmission shaft; a second gearbox, being transmission-connected to the first gearbox via a second transmission shaft, a third transmission shaft and a fourth transmission shaft being respectively connected to the two sides of the second gearbox; a blade roller, being transmission-connected to the third transmission shaft, and a screw pusher, being transmission-connected to the fourth transmission shaft.

[0006] Preferably, the third transmission shaft and the fourth transmission shaft are respectively arranged on two opposite sides of the second gearbox, and the third transmission shaft and the fourth transmission shaft are coaxially arranged.

[0007] Preferably, the third transmission shaft is connected to the end of the blade-flinging roller via a first transmission part, and a first bearing seat assembly is provided between the third transmission shaft and the first transmission part.

[0008] Preferably, the first transmission part includes: a first pulley, connected to the first bearing block assembly by a shaft; a flail roller pulley, installed at the end of the flail roller; and a first belt, with the first pulley and the flail roller pulley drivingly connected by the first belt.

[0009] Preferably, the fourth transmission shaft is connected to the end of the screw pusher through a second transmission part. The second transmission part and the first transmission part are respectively located on both sides of the baler. A second bearing block assembly is provided between the fourth transmission shaft and the second transmission part.

[0010] Preferably, the second transmission part includes: a second pulley, connected to the second bearing block assembly by a shaft; a screw pusher pulley, installed at the end of the screw pusher; and a second belt, with the second pulley and the screw pusher pulley drivingly connected by the second belt.

[0011] Preferably, the double-sided drive crushing mechanism further includes a towing beam, which is installed on the baler main body, and the first gearbox is installed on the towing beam.

[0012] Preferably, the towing beam includes a plurality of support beams. The first ends of the plurality of support beams are connected to the baler main body, and the second ends of the plurality of support beams are respectively connected to both sides of the first gearbox.

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

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

[0015] The bilateral drive crushing mechanism and baler according to the embodiments of the present invention have a PTO power input shaft provided on the first gearbox, and the power of the tractor is first input to the first gearbox. The first gearbox is drivingly connected to the baler main body through a first transmission shaft, and part of the power is transmitted to the baler main body. The second gearbox is drivingly connected to the first gearbox through a second transmission shaft, so that another part of the power of the first gearbox can be transmitted to the second gearbox. A third transmission shaft and a fourth transmission shaft are respectively connected to both sides of the second gearbox, the flail roller is drivingly connected to the third transmission shaft, and the screw pusher is drivingly connected to the fourth transmission shaft. With such a setting, the power of the second gearbox can be respectively transmitted to the flail roller and the screw pusher. Since the drive mode of the flail roller and the screw pusher is changed from series to parallel, the length of the shaft head and the cantilever of the flail roller can be effectively shortened. Such an improvement not only extends the service life of the flail roller, but also avoids the phenomenon of cracking of the crushing mechanism housing. In addition, by increasing the number of gearboxes, the load is reasonably dispersed, thereby improving the service life of the gearbox and significantly enhancing the smoothness of the power transmission process. In this way, the problems of unstable power output and cracking of the crushing mechanism housing easily caused by the existing drive form of the baler can be effectively solved.

[0024] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0025] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or sections, these components, elements, regions, layers, or sections are not limited by these terms.

[0030] As Figure 1 and Figure 2As shown, according to the first aspect of the present invention, a double-sided drive crushing mechanism is provided. The double-sided drive crushing mechanism includes a first gearbox 1, a second gearbox 2, a flail roller 3, and a screw pusher 4.

[0031] In the following description, reference will be made to Figure 1 and Figure 2 to specifically describe the specific structures of the above components of the double-sided drive crushing mechanism and the connection relationships of the above components.

[0032] As Figure 1 and Figure 2 shown, in the embodiment, the first gearbox 1 may be provided with a PTO power input shaft 11, so that power can be first input into the first gearbox 1. The first gearbox 1 may be drivingly connected to the baler main body 5 through a first transmission shaft 100, thereby transmitting a part of the power to the baler main body 5. The second gearbox 2 may be drivingly connected to the first gearbox 1 through a second transmission shaft 200, so that another part of the power of the first gearbox 1 can be transmitted to the second gearbox 2. The two sides of the second gearbox 2 may be respectively connected with a third transmission shaft 300 and a fourth transmission shaft 400. The flail roller 3 may be drivingly connected to the third transmission shaft 300, and the screw pusher 4 may be drivingly connected to the fourth transmission shaft 400. With such a setting, the power of the second gearbox 2 can be respectively transmitted to the flail roller 3 and the screw pusher 4. By changing the transmission mode of the flail roller 3 and the screw pusher 4 to a parallel connection, the length of the shaft head and the cantilever of the flail roller 3 can be effectively shortened, thereby avoiding cracking of the housing of the double-sided drive crushing mechanism. In addition, by increasing the number of gearboxes, the load can be reasonably dispersed, thereby significantly improving the smoothness of the power transmission process.

[0033] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the double-sided drive crushing mechanism may further include a towing beam 10. The towing beam 10 may be installed on the baler main body 5, and the first gearbox 1 may be installed on the towing beam 10. Specifically, the towing beam 10 may include a plurality of support beams 110 (which may be two as shown in the embodiment), and the plurality of support beams 110 may be respectively arranged on both sides of the first gearbox 1. One end of the towing beam 10 may be fixedly installed on the frame of the baler main body 5 through bolts, and the other end of the towing beam 10 may be installed on the outer shell of the first gearbox 1 through bolts.

[0034] Furthermore, preferably, as Figure 1As shown, in the embodiment, the outer shapes of the first transmission 1 and the second transmission 2 can be approximately rectangular parallelepipeds. The support beam 110 can include a longitudinal beam and a traction frame, and the traction frame can be obliquely connected to the longitudinal beam, so that a bent portion can be formed in the middle of the support beam 100, and further the support beams 110 on both sides of the first transmission 1 can be brought closer to the center. The two support beams 110 can be respectively connected to two opposite side surfaces of the first transmission 1, thereby fixing the first transmission 1. The PTO power input shaft 11 can be arranged on the side surface of the first transmission 1 away from the baler main body 5. The PTO power input shaft 11 can be in transmission connection with the PTO shaft of the tractor, and further transmit power to the first transmission 1.

[0035] More preferably, as Figure 1 and Figure 2 As shown, in the embodiment, the first transmission 1 can be arranged on the side of the second transmission 2 away from the baler main body 5. There is a gap between the first transmission 1 and the second transmission 2. The first transmission shaft 100 and the second transmission shaft 200 can be connected to the side surface of the first transmission 1 close to the baler main body 5. Among them, the first transmission shaft 100 can be arranged above the second transmission shaft 200, so that the first transmission shaft 100 is easy to be connected to the clutch of the baler main body 5, and the second transmission shaft 200 can connect the first transmission 1 and the second transmission 2, thereby avoiding interference between the first transmission shaft 100 and the second transmission shaft 200. The first transmission shaft 100 and the second transmission shaft 200 can be key-connected to the first transmission 1.

[0036] Preferably, as Figure 1 and Figure 2 As shown, in the embodiment, the third transmission shaft 300 and the fourth transmission shaft 400 can be respectively connected to two opposite side surfaces of the second transmission 2, and the second transmission shaft 200 can be connected to the side surface of the second transmission 2 close to the first transmission 1. The third transmission shaft 300 and the fourth transmission shaft 400 can be arranged coaxially, and the second transmission shaft 200 can be arranged perpendicular to the axes of the third transmission shaft 300 and the fourth transmission shaft 400.

[0037] Preferably, as Figure 1 and Figure 2As shown, in the embodiment, the flail knife roller 3 and the screw pusher 4 can be arranged parallel to the axes of the third transmission shaft 300 and the fourth transmission shaft 400. Among them, the third transmission shaft 300 can be connected to the end of the flail knife roller 3 through the first transmission part 6, and then transmit power to the flail knife roller 3. A first bearing seat assembly 7 can be arranged between the third transmission shaft 300 and the first transmission part 6. The fourth transmission shaft 400 can be connected to the end of the screw pusher 4 through the second transmission part 8, and then transmit power to the screw pusher 4. A second bearing seat assembly 9 can be arranged between the fourth transmission shaft 400 and the second transmission part 8. The first transmission part 6 and the second transmission part 8 can be respectively arranged on both sides of the baler to reserve sufficient installation space.

[0038] In the embodiment, since the flail knife roller 3 and the screw pusher 4 adopt a parallel transmission form, the load can be reasonably dispersed. The flail knife roller 3 and the screw pusher 4 can be respectively provided with a first bearing seat assembly 7 and a second bearing seat assembly 9, thereby avoiding damage to the bearings due to excessive force.

[0039] Further, preferably, as Figure 1 and Figure 2 shown, in the embodiment, the first transmission part 6 can include a first pulley 61, a flail knife roller pulley 62 and a first belt 63. Among them, the first pulley 61 can be connected to the first bearing seat assembly 7 through shaft transmission, so that the power of the third transmission shaft 300 can be transmitted to the first pulley 61 through the first bearing seat. The flail knife roller pulley 62 can be installed at the end of the flail knife roller 3. The flail knife roller pulley 62 can be connected to the first pulley 61 through the first belt 63, thereby being able to transmit the power of the second gearbox 2 to the flail knife roller 3.

[0040] In addition, preferably, as Figure 1 and Figure 2 shown, in the embodiment, the second transmission part 8 can include a second pulley 81, a screw pusher pulley 82 and a second belt 83. Among them, the second pulley 81 can be connected to the second bearing seat assembly 9 through shaft transmission, so that the power of the fourth transmission shaft 400 can be transmitted to the second pulley 81 through the second bearing seat. The screw pusher pulley 82 can be installed at the end of the screw pusher 4. The screw pusher pulley 82 can be connected to the second pulley 81 through the second belt 83, thereby being able to transmit the power of the second gearbox 2 to the screw pusher 4.

[0041] In addition, as Figure 1 and Figure 2As shown in the figure, a baler is provided according to the second aspect of the present invention. The baler includes a baler main body 5 and the bilateral drive crushing mechanism as described above. The bilateral drive crushing mechanism is installed on the baler main body 5.

[0042] During use, the baler can be drivingly connected to a tractor. The power of the tractor can be transmitted to the first gearbox 1 through the PTO power input shaft 11. The first gearbox 1 transmits a part of the power to the baler main body 5 through the first transmission shaft 100, and transmits another part of the power to the second gearbox 2 through the second transmission shaft 200. The third transmission shaft 300 and the fourth transmission shaft 400 are respectively arranged on both sides of the second gearbox 2. A part of the power of the second gearbox 2 is transmitted to the flail roller 3 through the third transmission shaft 300, and another part of the power of the second gearbox 2 is transmitted to the screw pusher 4 through the fourth transmission shaft 400. With such an arrangement, the transmission mode of the flail roller 3 and the screw pusher 4 can be changed to a parallel connection, thereby effectively shortening the length of the shaft head and the cantilever of the flail roller 3 to avoid cracking of the housing of the bilateral drive crushing mechanism. In addition, the first gearbox 1 and the second gearbox 2 are provided, which can also reasonably disperse the load, thereby significantly improving the smoothness of the power transmission process.
