[0043] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0044] The clutch drive device and harvester of the present invention will be described below with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown, the utility model provides a clutch driving device, wherein the clutch driving device includes:

[0046] Mounting body 100;

[0047] The driving assembly 200 is provided on the mounting body 100;

[0048] The swing arm assembly 300 includes a harvesting swing arm 310, a threshing swing arm 320, and a grain unloading swing arm 330. The three swing arms are rotatably connected to the mounting body 100 and are respectively connected to corresponding clutches. Each swing arm can drive the corresponding clutch to close.

[0049] The power plate 400 is rotatably disposed on the mounting body 100 and is provided with three force-applying parts, wherein at least one force-applying part is a cam part 410, and at least one force-applying part is a thrust body 420. The cam part 410 is used to push the threshing swing arm 320 to swing, so as to pull the corresponding clutch to close. The remaining two force-applying parts are used to push the harvesting swing arm 310 and the unloading swing arm 330 to swing respectively, so as to pull the corresponding clutch to close. The power plate 400 can rotate under the drive of the driving assembly 200, so that it can switch to the corresponding force-applying part to apply thrust under different working conditions.

[0050] When the above-mentioned clutch driving device is used, since it includes a mounting body 100, a driving assembly 200, a swing arm assembly 300 and a power plate 400, the swing arm assembly 300 includes a harvesting swing arm 310, a threshing swing arm 320 and a grain unloading swing arm 330. The three swing arms are all rotatably connected to the mounting body 100 and are respectively connected to corresponding clutches. Each swing arm can drive the corresponding clutch to close. The power plate 400 is rotatably arranged on the mounting body 100 and is provided with three force-applying parts. At least one of the three force-applying parts is set as a cam part 410. The setting of the cam part 410 as a force-applying part is to meet the requirements of being able to continuously push the threshing swing arm 320 to apply a closing pulling force to the corresponding clutch under harvesting conditions and threshing conditions. There is also at least one thrust body 420 among the three force-applying parts. The thrust body 420 is set as a force-applying part In order to meet the installation requirements of the remaining swing arms, except for the cam part 410 corresponding to the threshing swing arm 320, one of the remaining two force-applying parts can push the harvesting swing arm 310 to apply a closing pull to the corresponding clutch under the harvesting condition, and the other can push the unloading swing arm 330 to apply a closing pull to the corresponding clutch under the unloading condition. At the same time, the power plate 400 can be rotated under the drive of the drive component 200, so that under different working conditions, it can be switched to the corresponding force-applying part to apply thrust to the swing arm, thereby realizing the harvesting function, threshing function and unloading function respectively. Compared with the slot drive structure in the prior art, the cam part 410 and the thrust body 420 are used to push the corresponding swing arm to drive the clutch for closing, which significantly reduces the impact on the structural strength of the power plate 400 and achieves the purpose of facilitating pulling of large-load clutch.

[0051] It can be understood that the first ends of the three swing arms can be connected to the corresponding clutches through the tensioning components respectively, and the second ends of the three swing arms can be driven by the corresponding force-applying parts to swing in the direction of pulling the clutch to close.

[0052] Specifically, in the initial state, the three swing arms are restricted to the initial position of maintaining the corresponding clutch in the disconnected state; in the grain unloading condition, the power plate 400 can be rotated under the action of the drive component 200, and rotated to a force-applying portion to apply thrust to the grain unloading swing arm 330, so as to push the grain unloading swing arm 330 to pull the grain unloading clutch to close, while the other clutches remain in the disconnected state; in the threshing condition, the power plate 400 can be rotated under the action of the drive component 200, and rotated to the force-applying portion set as the cam portion 410. A thrust is applied to the threshing swing arm 320 to push the threshing swing arm 320 to pull the threshing clutch to close, while the other clutches remain in a disconnected state; under the harvesting condition, the power plate 400 can rotate under the action of the driving component 200, and rotate to the force-applying part set as the cam part 410 to apply a thrust to the threshing swing arm 320 and another force-applying part to apply a thrust to the harvesting swing arm 310, so as to push the threshing swing arm 320 and the harvesting swing arm 310 to pull the corresponding clutch to close, while the unloading clutch remains in a disconnected state.

[0053] More specifically, if Figure 3 As shown, the three clutches are all in the disconnected state. At this time, the harvester is in the driving condition, and the three force-applying parts have not started to apply thrust to the corresponding swing arms. The three swing arms are in the initial state. In order to ensure the stability of the grain unloading swing arm 330, the thrust body 420 corresponding to the grain unloading swing arm 330 can maintain an abutment state with the grain unloading swing arm 330; Figure 4 As shown, the grain unloading clutch is in a closed state, and the remaining two clutches are in a disconnected state. At this time, the harvester is in a grain unloading condition, specifically controlling the power plate 400 to rotate clockwise until the thrust body 420 pushes the grain unloading swing arm 330 to pull the grain unloading clutch to a closed state and stops rotating; Figure 5 As shown, the threshing clutch is in a closed state, and the remaining two clutches are in a disconnected state. At this time, the harvester is in a threshing working condition, specifically controlling the power plate 400 to rotate counterclockwise until the cam portion 410 pushes the threshing swing arm 320 to pull the threshing clutch in a closed state and stops rotating; Figure 6 As shown, the threshing clutch and the harvesting clutch are both in the closed state, and the grain unloading clutch is in the disconnected state. At this time, the harvester is in the harvesting condition, specifically controlling the power plate 400 to continue to rotate counterclockwise, and the cam portion 410 continues to abut against the threshing swing arm 320. At the same time, the thrust body 420 begins to abut against the harvesting swing arm 310 until the harvesting swing arm 310 is pushed to pull the harvesting clutch in the closed state and stops rotating.

[0054] In the embodiment of the present invention, the cam portion 410 and the thrust body 420 are respectively arranged on the outer peripheral contour of the power plate and the plate side 430 in a one-to-one correspondence. It should be noted that the outer peripheral contour of the power plate 400 and the plate side 430 are defined based on the rotation axis of the power plate 400 on the mounting body 100. The plate side 430 is the outer surface of the power plate 400 that is perpendicular to the rotation axis, and the outer peripheral contour is the outer surface of the power plate 400 that is arranged around the rotation axis. Two of the three force-applying parts are set as the side of the thrust body 420. The thrust body 420 is located at Opposite to the cam portion 410, one side of the threshing swing arm 320 is arranged facing the cam portion 410, and the cam portion 410 is used to abut against the threshing swing arm 320 and apply thrust to the threshing swing arm 320 under both threshing conditions and harvesting conditions. One side of the harvesting swing arm 310 and the unloading swing arm 330 are respectively arranged facing the two side surfaces of the thrust body 420 in a one-to-one correspondence, one of which is used to abut against the harvesting swing arm 310 and apply thrust to the harvesting swing arm 310 under harvesting conditions, and the other side is used to abut against the unloading swing arm 330 and apply thrust to the unloading swing arm 330 under unloading conditions. That is, in the present invention, the two force-applying parts for pushing the grain unloading swing arm 330 and the harvesting swing arm 310 can be set as the side of the thrust body 420, and then the power plate 400 only needs to be provided with a cam portion 410 for pushing the threshing swing arm 320. Compared with the solution of providing two cam portions 410 and one thrust body 420 on the power plate 400 to push three swing arms respectively, it can obviously play a role in reducing the area of ​​the power plate 400 and ensuring the strength of the power plate 400. It should be noted that the present invention can also choose to set one of the two force-applying parts for pushing the grain unloading swing arm 330 and the harvesting swing arm 310 as the side of the thrust body 420, and the other as the cam portion 410, that is, two cam portions 410 are provided on the power plate 400.

[0055] Specifically, if Figure 2As shown, the outer peripheral contour of one side of the power plate 400 is provided with a base circular surface 411, a cam portion 410, a connecting plane 412, a first air avoidance plane 413 and a second air avoidance plane 414. The base circular surface 411 is set on the first circumference with the rotation axis of the power plate 400 as the center line, and the cam portion 410 can be set on the second circumference with the rotation axis of the power plate 400 as the center line. The radius of the second circumference is greater than the radius of the first circumference. The cam portion 410 is connected to the base circular surface 411 through the connecting plane 412, and the first air avoidance plane 413 and the second air avoidance plane 414 are respectively arranged on the two outer sides of the base circular surface 411 and the cam portion 410. When the threshing swing arm 320 is in the initial state, the threshing swing arm 320 can abut against the base circular surface 411. When the threshing swing arm 320 is in the unloading condition, the power plate 400 rotates, and the threshing swing arm 320 maintains abutment against the base circular surface 411. When the threshing swing arm 320 is in the threshing condition and the harvesting condition, the power plate 400 rotates, and the threshing swing arm 320 abuts against the cam part 410.

[0056] See also Figure 1 as well as Figures 3 to 6 In this embodiment of the present invention, the harvesting swing arm 310 and the grain unloading swing arm 330 are located on the same side of the power plate 400 and are disposed on opposite sides of the thrust body 420, so that both sides of the thrust body 420, which are arranged facing away from each other, serve as force-applying portions. That is, the thrust body 420 used to propel the harvesting swing arm 310 and the grain unloading swing arm 330 are disposed on the same plate surface side 430 of the power plate 400, thereby saving installation space. It is also understandable that, in order to ensure that only one side of the thrust body 420 is active during both harvesting and grain unloading operations, the thrust body 420 is positioned between the harvesting swing arm 310 and the grain unloading swing arm 330. This allows the power plate 400 to rotate in opposite directions in both harvesting and grain unloading operations, pushing the corresponding swing arms. Of course, the present invention is not limited to this. The harvesting swing arm 310 and the grain unloading swing arm 330 can also be located on different sides of the power plate 400. In this case, the number of thrust bodies 420 should be two, and the two thrust bodies 420 are respectively arranged on the two opposite plate sides 430 of the power plate 400, and the side surfaces of the two thrust plates are respectively used to correspond one-to-one with the harvesting swing arm 310 and the grain unloading swing arm 330, and apply thrust to the corresponding swing arms.

[0057] In an embodiment of the present invention, there are two thrust bodies 420. The two thrust bodies 420 are spaced apart on one side of the power plate 400 along the rotation direction of the power plate 400. Both thrust bodies 420 are located between the harvesting swing arm 310 and the grain unloading swing arm 330, so that the sides of the two thrust bodies 420 facing away from each other serve as force-applying portions. The number of thrust bodies 420 is increased to two, and the sides of the two thrust bodies 420 are used to push the harvesting swing arm 310 and the grain unloading swing arm 330, respectively. Since the two thrust bodies 420 are spaced apart between the harvesting swing arm 310 and the grain unloading swing arm 330, the rotation angle of the power body is reduced when it is necessary to switch between the thrust bodies 420 to push different swing arms. Specifically, a connecting plate 421 is provided between the two thrust bodies 420 to connect the two thrust bodies 420. The connecting plate 421 serves to strengthen the structural strength. Of course, the present invention is not limited to this. The number of thrust bodies 420 can also be only one, that is, the diameter of the thrust body 420 is increased, and the two relatively arranged side surfaces of the thrust body 420 can also push the harvesting swing arm 310 and the unloading swing arm 330 respectively and one by one.

[0058] See also Figure 1 as well as Figures 3 to 6In an embodiment of the present invention, the first end of the threshing swing arm 320 and the first end of the harvesting swing arm 310 are both arranged upward, and the first end of the unloading swing arm 330 is arranged downward. Correspondingly, the second end of the threshing swing arm 320 and the second end of the harvesting swing arm 310 are both arranged downward, and the second end of the unloading swing arm 330 is arranged upward. Two first tensioning assemblies 500 that can move laterally are provided at intervals on the upper part of the mounting body 100. The first ends of the harvesting swing arm 310 and the threshing swing arm 320 are respectively connected to the corresponding clutches through the two first tensioning assemblies 500 in a one-to-one manner. A second tensioning assembly 600 that can move laterally is provided on the lower part of the mounting body 100. The first end of the unloading swing arm 330 is connected to the corresponding clutch through the second tensioning assembly 600, and the second tensioning assembly 600 and the two first tensioning assemblies 500 are both arranged to extend toward the side of the power plate 400 away from the cam portion 410. The choice of arranging the first ends of the threshing swing arm 320 and the first ends of the harvesting swing arm 310 facing upward, and the first end of the grain unloading swing arm 330 facing downward, facilitates both installation and observation of the movement of the power plate 400 and the swing arm assembly 300 when placed in the accommodation space formed by the mounting body 100. Furthermore, the addition of the first tensioning assembly 500 and the second tensioning assembly 600 facilitates connecting each swing arm to its corresponding clutch. Both the first tensioning assembly 500 and the second tensioning assembly 600 are arranged to be laterally movable through the mounting body 100, thereby guiding the movement of the first tensioning assembly 500 and the second tensioning assembly 600. Of course, the present invention is not limited to this embodiment; it is also acceptable for the first ends of the threshing swing arm 320 and the first ends of the harvesting swing arm 310 to both face downward, while the first end of the grain unloading swing arm 330 faces upward. However, the structure of the cam portion 410 used to push the threshing swing arm 320 would also need to be modified accordingly.

[0059] Furthermore, if Figure 1 、 Figure 2 and Figure 7As shown, the mounting body 100 includes a base plate 110 and two large-surface side plates 120, and the two large-surface side plates 120 stand on the base plate 110 at relative intervals, and the gap between the two large-surface side plates 120 forms an accommodating space for the power plate 400 and the swing arm assembly 300. A fixed shaft 130 is extended from the inner side of the large-surface side plate 120, and the power plate 400 is rotatably mounted on the fixed shaft 130. A first mounting plate 140 and a second mounting plate 150 are also provided on the inner side of the large-surface side plate 120. The first mounting plate 140 and the second mounting plate 150 are arranged in sequence from top to bottom on the side of the cam portion 410 away from the power plate 400. A first mounting hole for the two first tensioning assemblies 500 to pass through is formed on the first mounting plate 140, and a second mounting hole for the second tensioning assembly 600 to pass through is formed on the second mounting plate 150. In addition, the first tensioning assembly 500 and the second tensioning assembly 600 may be configured to include tension rods or tension wires.

[0060] In the embodiment of the present invention, the power plate 400, the second end of the harvesting swing arm 310, and the second end of the grain unloading swing arm 330 are coaxially rotatably mounted on the mounting body 100. Specifically, a fixed shaft 130 is provided on the mounting body 100, and the power plate 400, the second end of the harvesting swing arm 310, and the second end of the grain unloading swing arm 330 are all sleeved on the fixed shaft 130. This simplifies the structure and saves installation space. It also ensures that the deflection motion of the harvesting swing arm 310 and the grain unloading swing arm 330 is concentric with the rotation of the thrust body 420, thereby improving the deflection stability of the swing arms.

[0061] See also Figures 3 to 7 In an embodiment of the present utility model, a stopper 160 is provided on the mounting body 100. The stopper 160 is used to abut against the swing arm and limit the swing arm from swinging in the direction of relaxing the tensioning assembly. That is, when the clutch is in the disconnected state, the addition of the stopper 160 can ensure that the three swing arms are stably tensioned in connection with the clutch. It should be noted that at this time, the force applied to the swing arm by the stopper 160 is only enough to tension the tensioning assembly between the swing arm and the clutch, and cannot extend the spring in the clutch. Specifically, the mounting body 100 is provided with a stopper 160 at a position near the second end of the harvesting swing arm 310, the threshing swing arm 320 and the unloading swing arm 330. The stopper 160 is used to abut against the second end of the corresponding swing arm to limit the swing arm from swinging in the direction of relaxing the tensioning assembly.

[0062] Please see again Figures 3 to 7In the embodiment of the present utility model, the stopper 160 includes a stopper plate 161 and a stopper column 162. The mounting body 100 is provided with a stopper plate 161 as a stopper 160 on the side of the second end of the threshing swing arm 320 facing away from the cam portion 410. When the threshing clutch is in the disconnected state, since the stopper plate 161 is fixedly arranged and can stop the second end of the threshing swing arm 320, the second end of the threshing swing arm 320 cannot swing toward the side where the stopper plate 161 is located, thereby allowing the first end of the threshing swing arm 320 connected to the tensioning assembly to maintain tension on the tensioning assembly. Specifically, the stopper plate 161 stands on the bottom plate 110 of the mounting body 100, and the side of the stopper plate 161 facing the power plate 400 is also provided with a deflection shaft for the threshing swing arm 320 to be deflected and installed. In addition, the second ends of the harvesting swing arm 310 and / or the grain unloading swing arm 330 are each formed with a hook plate portion 340, which bends and extends from the second end of the corresponding swing arm toward the side away from the corresponding clutch. The mounting body 100 is provided with a stop post 162 that can serve as a stop member 160. The stop post 162 can be used for alignment and abutment with the inner side of the hook plate portion 340. The stop post 162 can be specifically provided on the large side plate 120 of the mounting body 100. When the harvesting clutch and / or the grain unloading clutch are in the disconnected state, the addition of the hook plate portion 340 and the stop post 162 can restrict the second end of the corresponding swing arm from swinging toward the direction of loosening the tensioning assembly. It should be noted that the inner side of the hook plate portion 340 refers to the side of the hook plate portion 340 where the hookable space is formed.

[0063] Specifically, when the second end of the harvesting swing arm 310 and the second end of the grain unloading swing arm 330 are coaxially rotatably arranged, the harvesting swing arm 310 and the grain unloading swing arm 330 can share a stop column 162, and the hook plate portion 340 of the harvesting swing arm 310 and the hook plate portion 340 of the grain unloading swing arm 330 are respectively arranged on opposite sides of the stop column 162. The second end of the harvesting swing arm 310 is arranged downward, so that the hook plate portion 340 on the harvesting swing arm 310 can be located on the lower side of the stop column 162, and the second end of the grain unloading swing arm 330 is arranged upward, so that the hook plate portion 340 on the grain unloading swing arm 330 can be located on the upper side of the stop column 162.

[0064] In an embodiment of the present invention, the thrust body 420 is configured as a cylinder, and the harvesting swing arm 310 and / or the grain unloading swing arm 330 are both formed with a notch 350 that fits the circumference of the thrust body 420. The notch 350 is configured as a semicircle that cooperates with the cylinder to enhance the stability of the swing arm's swinging motion and reduce wear.

[0065] Please see again Figure 1 and Figure 2In the embodiment of the present invention, a fixed shaft 130 is provided on the mounting body 100, and a power plate 400 is rotatably mounted on the fixed shaft 130. A gear portion 440 is formed on the side of the power plate 400 facing away from the cam portion 410. The drive assembly 200 includes a rotary drive member 210 provided on the mounting body 100 and a driving gear 220 meshingly connected to the gear portion 440. The radius of the driving gear 220 is smaller than the radius of the gear portion 440. The rotary drive member 210 drives the power plate 400 to rotate via the driving gear 220. That is, the power plate 400 is driven by a gear meshing transmission. Since the radius of the driving gear 220, which acts as the driving gear 220, is smaller than the radius of the gear portion 440, which acts as the driven gear, the output torque of the rotary drive member 210 can be reduced, which is more conducive to the matching of the rotary drive member 210. Specifically, the rotary drive member 210 can be disposed outside the mounting body 100, with the output shaft of the rotary drive member 210 extending into the housing of the mounting body 100 and being mounted on the driving gear 220. The rotary drive member 210 includes, but is not limited to, a motor. Of course, the present invention is not limited to this embodiment. The rotary drive member 210 can also be directly connected to the power plate 400, such as a hollow rotating platform, with the fixed shaft 130 being mounted therethrough.

[0066] Therefore, the utility model adopts the power plate 400 to drive the swing arm to realize the clutch function, which has the advantages of compact structure and high strength, and can drive a large-load clutch; the drive component 200 drives the power plate 400 through gear engagement, which can reduce the output torque of the motor and is more conducive to the matching of the motor.
