Description

Technical Field

[0001] The utility model belongs to the technical field of balers, and in particular relates to a feeding fork mechanism for a double-bundle baler and a power mechanism for a double-bundle baler. Background Art

[0002] Balers are the most popular agricultural equipment for baling straw or forage in my country. Although the balers currently used, especially square balers, have high baling efficiency, they can only bale one channel at a time and cannot achieve baling more efficiently.

[0003] In order to improve the baling efficiency, the applicant has developed a double-bundle knotter-type square baler, which uses two baling mechanisms to effectively improve the baling efficiency. The technical solution was submitted on November 18, 2024 and was authorized on January 3, 2025. The authorization announcement number is CN222284028U. Although this technical solution effectively improves the baling efficiency, it still has defects such as complex transmission structure, high cost due to the large number of transmission parts, and is not conducive to popularization and use. Utility Model Content

[0004] The utility model provides a feeding fork mechanism for a double-outlet baler and a power mechanism for the double-outlet baler, which use a symmetrical transmission structure and a linked feeding fork mechanism to simplify the overall transmission structure.

[0005] The technical solution adopted by the utility model is:

[0006] A power mechanism for a double-bale baler comprises a double-shaft transmission structure and two baling mechanism power transmission structures, the double-shaft transmission structure has two symmetrical output ends, each of which is in transmission connection with a baling mechanism power transmission structure; each of the baling mechanism power transmission structures comprises a shift fork power structure, a knotter power structure, and a picking power structure; the picking power structure is located below the shift fork power structure, and the knotter power structure is located above the shift fork power structure; the two shift fork power structures are connected to the feeding fork mechanism and transmit power to the feeding fork mechanism to drive the feeding fork mechanism to operate; each of the shift fork power structures comprises a shift fork power receiving wheel and a power transmission wheel, the shift fork power receiving wheel and the corresponding picking power structure are in transmission connection with the power output wheel at the output end through the same transmission member, and the power transmission wheel is in transmission connection with the corresponding knotter power structure. The symmetrically arranged power transmission structure of the baling mechanism makes the power layout of the double-outlet baler identical, and the number of transmission components used in each baling mechanism power transmission structure is small, which is greatly simplified compared to the transmission in the background technology. Only the two feeding fork structures of the feeding fork mechanism are linked by a double-bearing fixed seat, but the power is also transmitted separately, that is to say, the two bale-out structures of the double-outlet baler are completely identical in structure.

[0007] As a preferred embodiment of the present utility model, the feeding fork mechanism includes a first feeding fork structure and a second feeding fork structure. A double-bearing fixed seat is arranged between the first feeding fork structure and the second feeding fork structure. The double-bearing fixed seat includes a fixed seat body and bearings. A bearing is installed on one side of the fixed seat body facing the first feeding fork structure, and the third connecting rod of the first feeding fork structure is fixedly connected to the bearing. A bearing is also installed on the other side of the fixed seat body facing the second feeding fork structure, and the third connecting rod of the second feeding fork structure is fixedly connected to the bearing. The axes of the two bearings coincide. The first feeding fork structure and the second feeding fork structure have the same structure and are symmetrically arranged in position. They are connected by a double-bearing fixed seat at adjacent positions. The double-bearing fixed seat provides an installation position for the two feeding fork structures. For a baler with a double-outlet bale structure, the two feeding fork structures can be linked together, but they can operate independently of each other without affecting each other during operation.

[0008] As a preferred embodiment of the present utility model, both the first feeding fork structure and the second feeding fork structure include a fork power connection frame and a fork assembly. The fork power connection frame includes a first connecting rod, a first connecting plate, a second connecting rod, a second connecting plate, and a third connecting rod. The first connecting plate and the second connecting plate are arranged in the same direction. The first connecting rod serves as a fork power receiving shaft. The first connecting rod is installed on the frame through a bearing and can rotate around the installation position. The first connecting rod is fixedly connected to one end of the first connecting plate. The other end of the first connecting plate is fixedly connected to one end of the second connecting rod. The other end of the second connecting rod is fixedly connected to one end of the second connecting plate. The other end of the second connecting plate is fixedly connected to one end of the third connecting rod. The other end of the third connecting rod is fixedly connected to the bearing. The axes of the first connecting rod, the third connecting rod, and the bearing coincide. The fork assembly includes a fork sleeve shaft, a fork, a fork bearing, a swing arm connecting plate, and a fork swing arm. The fork sleeve shaft is sleeved on the second connecting rod through the fork bearing. A swing arm connecting plate and several forks are installed on the outer circumferential wall of the fork sleeve shaft. The swing arm connecting plate is located at a position of the fork sleeve shaft close to the double-bearing fixed seat. The end of the swing arm connecting plate away from the fork sleeve shaft is hinged to one end of the fork swing arm. The other end of the fork swing arm is hinged to the frame. Initially, the fork sleeve shaft can rotate together with the second connecting rod to bring the fork to a high position to realize grass raking. When it rotates to the high position and is restricted by the fork swing arm, the fork sleeve shaft rotates relative to the second connecting rod to make the fork return to the low position again, realizing the feeding of the forage by the fork.

[0009] As a preferred embodiment of the present utility model, a fork power receiving wheel and a power transmission wheel are fixedly installed on the first connecting rod of the first feeding fork structure and the first connecting rod of the second feeding fork structure. The fork power receiving wheel and the power transmission wheel are fixed to the first connecting rod. After the fork power receiving wheel receives the power of the double-shaft transmission structure, it drives the first connecting rod to rotate. The first connecting rod drives the first connecting plate, the second connecting rod, the second connecting plate, and the third connecting rod to rotate. The fork sleeve shaft is initially located at a low position and rotates together with the second connecting rod, bringing the fork to a high position to realize weed raking. When it rotates to the high position and is restricted by the fork swing arm, the fork sleeve shaft rotates relative to the second connecting rod, causing the fork to return to the low position again. However, the first connecting rod still drives the first connecting plate, the second connecting rod, the second connecting plate, and the third connecting rod to rotate normally.

[0010] As a preferred embodiment of the present utility model, each of the knotter power structures includes a knotter power receiving wheel and a knotter power shaft. The knotter power receiving wheel is installed on the knotter power shaft, and the knotter power receiving wheel is in transmission connection with the power transmission wheel.

[0011] As a preferred embodiment of the present utility model, each of the pickup power structures includes a pickup power receiving wheel, a pickup power receiving shaft, a pickup power distribution wheel, a pickup shaft, and a pickup power wheel. The pickup power receiving wheel and the pickup power distribution wheel are installed on the pickup power receiving shaft. The pickup power receiving wheel and the fork power receiving wheel are in transmission connection with the power output wheel at the output end through the same transmission member. The pickup power distribution wheel is in transmission connection with the pickup power wheel. The pickup power wheel is installed on the pickup shaft, and the pickup shaft is located below the pickup power receiving shaft.

[0012] As a preferred embodiment of the present utility model, a tensioning wheel is provided between the pickup power receiving wheel and the fork power receiving wheel.

[0013] As a preferred embodiment of the present utility model, the dual-axis drive structure includes a gearbox and a transmission mechanism. The gearbox has two power output shafts and one power input shaft. The two power output shafts are symmetrical. Each power output shaft is connected with a transmission mechanism. Each of the transmission mechanisms includes a crank and a transmission shaft. The transmission shaft coincides with the axis of the power output shaft. The transmission shaft and the power output shaft are connected by the crank. A piston connecting portion is provided on the crank. The piston connecting portion is connected with the piston of the double-outlet baler and drives the piston to reciprocate. At the end of the transmission shaft far away from the crank, a main power transmission wheel is provided. The main power transmission wheel is in transmission connection with the corresponding fork power receiving wheel and the pickup power receiving wheel, driving the fork power receiving wheel and the pickup power receiving wheel to rotate. One gearbox drives two baling mechanisms simultaneously. The connection between the crank and the power output shaft is through a spline. When the spline positions where the two cranks are installed are different, the operations of the two transmission mechanisms can be asynchronous. At this time, the two transmission mechanisms are asynchronous, and the pistons, forks, knotting, and pickups driven by them are also asynchronous, forming a structure that is symmetrical in layout but asymmetrical in operation. When the spline positions where the two cranks are installed are the same, the operations of the two transmission mechanisms are synchronous, and correspondingly, the pistons, forks, knotting, and pickups driven by them are also synchronous, forming a completely symmetrical layout.

[0014] The present utility model uses one gearbox to drive two baling mechanisms simultaneously, and the power transmission structures of the two baling mechanisms are completely the same. According to the connection relationship between the crank and the gearbox, they can operate synchronously or asynchronously. Moreover, the feeding fork structures of the two baling mechanisms are the same, and a double-bearing fixing seat is used for assembly at the adjacent position to ensure the symmetrical distribution of the two baling mechanisms.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] A power mechanism for a double-bale baler, such as Figure 4 and 5 As shown, it comprises a double-shaft transmission structure 6 and two baling mechanism power transmission structures 7 . The double-shaft transmission structure 6 has two symmetrical output ends, and each output end is in driving connection with one baling mechanism power transmission structure 7 .

[0024] Each of the baling mechanism power transmission structures 7 comprises a fork power structure, a knotter power structure, and a picking power structure; the picking power structure is located below the fork power structure, and the knotter power structure is located above the fork power structure; the two fork power structures are connected to the feeding fork mechanism and transmit power to the feeding fork mechanism, such as Figure 3 As shown, the first feeding fork structure and the second feeding fork structure are driven to operate asynchronously.

[0025] Each of the fork power structures includes a fork power receiving wheel 711 and a power transmission wheel 712. The fork power receiving wheel 711 and the corresponding picking power structure are connected to the power output wheel at the output end through the same transmission member. The power transmission wheel 712 is connected to the corresponding knotter power structure. Chain transmission is used in this embodiment.

[0026] like Figure 6As shown in the figure, the double-axis drive structure 6 includes a gearbox 61 and a transmission mechanism 62. The gearbox 61 has two power output shafts 63 and one power input shaft. The two power output shafts 63 are symmetric. Each power output shaft 63 is connected to a transmission mechanism 62. Each of the transmission mechanisms 62 includes a crank 621 and a transmission shaft 622. The transmission shaft 622 coincides with the axis of the power output shaft 63. The transmission shaft 622 is connected to the power output shaft 63 through the crank 621. A piston connection part is arranged on the crank 621. The piston connection part is connected to the piston of the double-outlet baler and drives the piston 8 to reciprocate, so as to compress the fed forage into bales.

[0027] The crank has two connecting plates, and the two connecting plates are connected by a shaft, and this shaft connecting the two connecting plates is the piston connection part. And the crank is connected to the power output shaft through a spline. When the spline positions where the two cranks are installed are different, the operations of the two transmission mechanisms can be asynchronous, that is, the pistons, fork shifters, knotting, and picking up driven by the two transmission mechanisms are also asynchronous, and the two baling mechanisms operate independently, only being approximately symmetric in layout. This embodiment is the case of asynchronous operation. Of course, when the spline positions where the two cranks are installed are the same, the operations of the two transmission mechanisms are synchronous, and correspondingly, the pistons, fork shifters, knotting, and picking up driven by each of them are also synchronous, forming a completely symmetric layout.

[0028] At the end of the transmission shaft 622 far from the crank 621, a main power transmission wheel 623 is arranged. The main power transmission wheel 623 is in transmission connection with the corresponding fork shifter power receiving wheel 711 and the picking power receiving wheel 731, driving the fork shifter power receiving wheel and the picking power receiving wheel to rotate.

[0029] Specifically, the feeding fork shifter mechanism includes a first feeding fork shifter structure 1 and a second feeding fork shifter structure 2. The first feeding fork shifter structure and the second feeding fork shifter structure are the same, and both include a fork shifter power connection frame and a fork shifter assembly; as Figure 1 and 2 shown, the fork shifter power connection frame includes a first connecting rod 41, a first connecting plate 42, a second connecting rod 43, a second connecting plate 44, and a third connecting rod 45. The first connecting plate 42 and the second connecting plate 44 are arranged in the same direction; the first connecting rod 41 serves as a fork shifter power receiving shaft. The first connecting rod 41 is installed on the frame through a bearing and can rotate around the installation position; the first connecting rod 41 is fixedly connected to one end of the first connecting plate 42. The other end of the first connecting plate 42 is fixedly connected to one end of the second connecting rod 43. The other end of the second connecting rod 43 is fixedly connected to one end of the second connecting plate 44; the other end of the second connecting plate 44 is fixedly connected to one end of the third connecting rod 45. The other end of the third connecting rod 45 is fixedly connected to the bearing 32; the axes of the first connecting rod 41, the third connecting rod 45, and the bearing 32 coincide.

[0030] The described fork assembly includes a fork sleeve shaft 51, a fork 52, a fork bearing 53, a swing arm connecting plate 54, and a fork swing arm 55; the fork sleeve shaft 51 is sleeved on the second connecting rod 43 through the fork bearing 53. A swing arm connecting plate 54 and several forks 52 are installed on the outer circumferential wall of the fork sleeve shaft 51. The swing arm connecting plate 54 is located at a position of the fork sleeve shaft 51 close to the double-bearing fixed seat 3. One end of the swing arm connecting plate 54 away from the fork sleeve shaft 51 is hinged to one end of the fork swing arm 55, and the other end of the fork swing arm 55 is hinged to the frame.

[0031] A double-bearing fixed seat 3 is arranged between the first feeding fork structure 1 and the second feeding fork structure 2. The described double-bearing fixed seat 3 includes a fixed seat body 31 and bearings 32. A bearing 32 is installed on one side of the fixed seat body 31 facing the first feeding fork structure, and the third connecting rod of the first feeding fork structure is fixedly connected to the bearing 32; a bearing 32 is also installed on the other side of the fixed seat body 31 facing the second feeding fork structure, and the third connecting rod of the second feeding fork structure 2 is fixedly connected to the bearing 32; the axes of the two bearings 32 coincide.

[0032] The first feeding fork structure 1 and the second feeding fork structure 2 have the same structure and are symmetrically arranged. The adjacent positions are connected by a double-bearing fixed seat. The double-bearing fixed seat provides an installation position for the two feeding fork structures. For a baler with a double-bale-out structure, the two feeding fork structures can be linked together, but they can operate independently of each other and do not affect each other during operation.

[0033] As Figure 3 shown, because the feeding fork mechanism has two feeding fork structures, fork power receiving wheels 711 and power transmission wheels 712 are fixedly installed on the first connecting rod 41 of the first feeding fork structure and the first connecting rod 41 of the second feeding fork structure.

[0034] The fork power receiving wheels 711 and the power transmission wheels 712 are fixed to the first connecting rod 41. After the fork power receiving wheels 711 receive the power of the double-shaft transmission structure, they drive the first connecting rod to rotate. The first connecting rod 41 drives the first connecting plate, the second connecting rod, the second connecting plate, and the third connecting rod to rotate. The fork sleeve shaft is initially located at a low position and rotates together with the second connecting rod 43, bringing the fork to a high position to realize grass raking; when it rotates to the high position and is restricted by the fork swing arm 55, the fork sleeve shaft 51 rotates relative to the second connecting rod 43, causing the fork to return to the low position again, but the first connecting rod 41 still drives the first connecting plate, the second connecting rod, the second connecting plate, and the third connecting rod to rotate normally.

[0035] Each of the knotter power structures includes a knotter power receiving wheel 721 and a knotter power shaft. The knotter power receiving wheel 721 is installed on the knotter power shaft, and the knotter power receiving wheel 721 is in driving connection with the power transmission wheel 712.

[0036] Each of the pickup power structures includes a pickup power receiving wheel 731, a pickup power receiving shaft 732, a pickup power distribution wheel 734, a pickup shaft, and a pickup power wheel 735. A tension wheel 74 is provided between the pickup power receiving wheel 731 and the fork power receiving wheel 711. The pickup power receiving wheel 731 and the pickup power distribution wheel 734 are installed on the pickup power receiving shaft 732. The pickup power receiving wheel 731 and the fork power receiving wheel 711 are in driving connection with the main power transmission wheel 623 at the output end through the same transmission member. The pickup power distribution wheel 734 is in driving connection with the pickup power wheel 735. The pickup power wheel 735 is installed on the pickup shaft, and the pickup shaft is located below the pickup power receiving shaft 732.

[0037] The main power transmission wheel 623 on each side is in driving connection with the fork power receiving wheel 711 and the pickup power receiving wheel 731 through the same chain, driving the fork power receiving wheel and the pickup power receiving wheel to rotate. After the fork power receiving wheel 711 receives power, it drives the first connecting rod to rotate. The first connecting rod 41 drives the first connecting plate, the second connecting rod, the second connecting plate, and the third connecting rod to rotate. The fork sleeve shaft is initially located at a low position and rotates together with the second connecting rod 43, bringing the fork to a high position to realize grass raking. When it rotates to the high position and is restricted by the fork swing arm 55, the fork sleeve shaft 51 rotates relative to the second connecting rod 43, causing the fork to return to the low position again. However, the first connecting rod 41 still drives the first connecting plate, the second connecting rod, the second connecting plate, and the third connecting rod to rotate normally, realizing the feeding of forage by the fork.

[0038] The pickup power receiving wheel drives the pickup power receiving shaft 732 to rotate, thereby driving the pickup power distribution wheel 734 to rotate. The pickup power distribution wheel 734 drives the pickup power wheel 735 to rotate through a belt or a chain. The pickup power wheel 735 drives the pickup shaft to rotate, and then drives the pickup claws on the pickup shaft to rotate to realize the pickup of materials.

[0039] The knotter power receiving wheel 721 is driven by the power transmission wheel 712. The knotter power receiving wheel 721 drives the knotter power shaft to rotate, and then drives the knotting mechanism installed on the knotter power shaft to tie the binding ropes for the forage.
