Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a double-moving knife cutter and a harvester. Background Art

[0002] A harvester is an integrated machine for harvesting crops. It has the operation process of harvesting, threshing, and collecting the grains into a storage bin. Then, the grains and other food can be transported to a preset location or a transport vehicle through a transmission structure.

[0003] During the harvesting process, the harvester cuts the rice plants through the reciprocating motion between the moving blade and the fixed blade. The reciprocating motion of the moving blade generates inertia force and impact load, which causes resonance in other moving parts of the whole machine.

[0004] In the related art, the reciprocating motion of the double movable blade structure can be used to reduce the resonance phenomenon of the whole machine. However, due to the poor coordination between the two sets of movable blades of the double movable blade structure, the resonance phenomenon of the whole machine cannot be effectively reduced, and may even aggravate the resonance phenomenon of the whole machine. Utility Model Content

[0005] In view of this, the utility model provides a double-moving blade cutter and a harvester to solve the problem of poor coordination between two sets of moving blades in a double-moving blade structure.

[0006] On the one hand, the utility model provides a double movable knife cutter, including a double movable knife combination, a first drive mechanism, a second drive mechanism and a reel-pulling rotary shaft. The double movable knife combination includes a first movable knife group and a second movable knife group. The first drive mechanism includes a first drive assembly and a first crank assembly, and the first drive assembly is connected to the first movable knife group through the first crank assembly. The second drive mechanism includes a second drive assembly and a second crank assembly, and the second drive assembly is connected to the second movable knife group through the second crank assembly. One end of the reel-pulling rotary shaft is connected to the first drive assembly, and the other end of the reel-pulling rotary shaft is connected to the second drive assembly, so that the first drive assembly and the second drive assembly operate synchronously.

[0007] Beneficial effects: The first drive assembly can convert the rotational motion into a reciprocating telescopic motion through the first crank assembly, and the second drive assembly can also convert the rotational motion into a reciprocating telescopic motion through the second crank assembly. Since the first drive assembly and the second drive assembly are connected by synchronous transmission through the reed-plowing rotary shaft, the first crank assembly and the second crank assembly can be made to move synchronously in the same direction or synchronously in opposite directions by adjusting the configuration. Combined with the difference in the structure and installation position of the first crank assembly and the second crank assembly, the synchronous movement of the first crank assembly and the second crank assembly in the same direction or synchronous movement in opposite directions can realize the synchronous opposite cutting movement of the first moving knife group and the second moving knife group.

[0008] The first moving knife group generates inertia force and impact load during the cutting movement, and the second moving knife group also generates reverse inertia force and reverse impact load during the synchronous reverse cutting movement. Since the two inertia forces and the two impact loads in opposite directions at least partially offset each other, the inertia force and impact load generated by the double moving knife combination during the reciprocating cutting movement are greatly reduced. Even when the two reverse inertia forces are equal or approximately equal in magnitude, and the two reverse impact loads are equal or approximately equal in magnitude, the double moving knife combination will not generate inertia force and impact load during the reciprocating cutting movement or will be almost zero.

[0009] In this way, the double moving knife combination can reach a dynamic balance state or a state close to dynamic balance state during the reciprocating cutting motion, so that the first moving knife group and the second moving knife group can offset each other's impulses and reduce the overall vibration, and have a better coordination state, thereby achieving the effect of offsetting the load impulse and reducing the vibration amplitude, so as to avoid resonance with other moving parts of the whole machine. This is conducive to improving the use experience and service life of the double moving knife cutter, and improving the stability of the whole machine.

[0010] In an optional embodiment, the first drive assembly and the second drive assembly are spaced apart along the axial direction of the reel rotating shaft. Along the axial direction of the reel rotating shaft, one end of the first drive assembly away from the second drive mechanism is transmission-connected to one end of the reel rotating shaft, and one end of the second drive assembly away from the first drive mechanism is transmission-connected to the other end of the reel rotating shaft.

[0011] Beneficial effects: The first drive assembly and the second drive assembly are synchronously connected to the reel rotating shaft through two ends far away from each other, which facilitates the assembly operation of the transmission structure.

[0012] In an optional embodiment, the two ends of the reel rotating shaft are transmission-connected with a first transmission wheel and a second transmission wheel. The first drive assembly includes a first drive shaft and a first drive wheel. Along the axial direction of the reel rotating shaft, the end of the first drive shaft away from the second drive mechanism is provided with a first drive wheel, and the first transmission wheel is transmission-connected with the first drive wheel. The second drive assembly includes a second drive shaft and a second drive wheel. Along the axial direction of the reel rotating shaft, the end of the second drive shaft away from the first drive mechanism is transmission-connected with the second drive wheel, and the second transmission wheel is transmission-connected with the second drive wheel, so that the first drive wheel and the second drive wheel rotate synchronously.

[0013] Beneficial effect: Through the transmission connection between the first transmission wheel and the first drive wheel, and the transmission connection between the second transmission wheel and the second drive wheel, it is convenient to flexibly arrange the installation positions of the first drive shaft and the second drive shaft in the radial direction of the reel rotating shaft.

[0014] In an optional embodiment, along the axial direction of the reel rotating shaft, at least one of an end of the first drive shaft close to the second drive mechanism and an end of the second drive shaft close to the first drive mechanism is configured as a power input end.

[0015] Beneficial effect: Since the two ends of the first drive assembly and the second drive assembly that are far away from each other are synchronously connected through the reed-pulling rotating shaft, at least one end of the first drive assembly and the second drive assembly that are close to each other can be set as the power input end, so that the power of the harvester can drive the double movable knife combination to perform synchronous reverse cutting movement through the first drive mechanism, the second drive mechanism and the reed-pulling transmission mechanism.

[0016] In an optional embodiment, the second driving assembly includes a second driving wheel, and one end of the second driving shaft close to the first driving mechanism is transmission-connected to the second driving wheel, and the second driving wheel is configured as a power input end.

[0017] Beneficial effect: By setting the second driving wheel as the power input end, through the transmission connection of the second driving shaft, the second driving wheel, the second transmission wheel, the reel rotating shaft, the first transmission wheel and the first driving wheel, the second driving wheel and the first driving wheel on both sides of the cutting table body can be made to rotate synchronously, thereby driving the second moving knife group and the first moving knife group to synchronously reverse cutting movement.

[0018] In an optional embodiment, the first drive assembly includes a first driving wheel and an auger driving wheel, the end of the first driving shaft close to the second driving mechanism is connected to the first driving wheel, and the first driving wheel is configured as a power input end. The end of the first driving shaft away from the second driving mechanism is connected to the auger driving wheel for driving the cutter auger to rotate.

[0019] Beneficial effect: By setting the first driving wheel at the power input end at one end of the first driving shaft, the second driving wheels on the left and right sides of the cutting table body can also be rotated synchronously with the first driving wheel through the transmission connection of the first driving assembly, the first transmission wheel, the reel rotating shaft, the second transmission wheel and the second driving wheel, thereby driving the second moving knife group and the first moving knife group to synchronously cut in the opposite direction. On this basis, by transmission connecting the auger driving wheel at the end of the first driving shaft away from the first driving wheel, the first driving assembly can also drive the cutting table auger to rotate.

[0020] In an optional embodiment, the first drive assembly further includes a drive bearing, and the first drive wheel is connected to the first drive shaft via the drive bearing. Alternatively, the first drive wheel is in driving connection with the first drive shaft.

[0021] Beneficial effect: At the end of the first drive shaft away from the first driving wheel, the first drive wheel is connected to the end of the first drive shaft through a drive bearing, which is used for positioning and installing the first drive wheel, but the drive bearing avoids the transmission connection between the first drive shaft and the first drive wheel. By setting the first drive wheel and the first drive bearing to be non-transmission connected, it can be avoided that the first drive shaft drives the first moving knife group and the cutting table auger to rotate at the same time, so as to achieve differential transmission between the double moving knife combination and the cutting table auger. At this time, the first drive shaft has a smaller transmission load, which is conducive to improving the overall stability of the first drive assembly.

[0022] Alternatively, the first drive wheel may be directly connected to the first drive shaft in driving connection, that is, there is no need to set a differential transmission between the double movable knife assembly and the cutting table auger, and the structure is simple.

[0023] In an optional embodiment, the double-movable blade cutter further includes a reel driving wheel and a reel bearing, wherein the reel driving wheel is connected to one end of the reel rotating shaft via the reel bearing, and the reel driving wheel is used to drive the reel wheel to rotate.

[0024] Beneficial effect: By setting the reel bearing, it can be avoided that the reel driving wheel drives the reel rotating shaft to rotate while driving the reel wheel to rotate.

[0025] In an optional embodiment, the first crank assembly includes a first eccentric member, a first connecting rod and a first rocker member. The first driving wheel is connected to the first eccentric member at a position radially away from the axis, and the first eccentric member is connected to the first moving knife assembly through the first connecting rod and the first rocker member.

[0026] And / or, the second crank assembly includes a second eccentric member, a second connecting rod and a second rocker member. The second driving wheel is connected to the second eccentric member at a position radially away from the axis, and the second eccentric member is connected to the second moving knife group through the second connecting rod and the second rocker member, so that the first moving knife group and the second moving knife group can synchronously cut in opposite directions along the axial direction of the reel rotating shaft.

[0027] Beneficial effect: The first driving wheel drives the first moving knife group to perform reciprocating cutting motion in the axial direction of the reel rotating shaft through the first eccentric member, the first connecting rod and the first rocker member, and the second driving wheel drives the second moving knife group to perform reciprocating cutting motion in the axial direction of the reel rotating shaft through the second eccentric member, the second connecting rod and the second rocker member. Since the first driving wheel rotates synchronously with the second driving wheel, the first crank assembly and the second crank assembly on both sides of the cutting table body can be configured as two sets of components that are symmetrically arranged, so that the first moving knife group and the second moving knife group driven by the first crank assembly and the second crank assembly perform synchronous reverse cutting motion along the axial direction of the reel rotating shaft, which is beneficial to reduce or offset the inertia force and impact load of the double moving knife combination.

[0028] On the other hand, the utility model provides a harvester, comprising the double-moving blade cutter of any one of the above aspects.

[0029] Beneficial effects: Since the harvester includes the double-moving blade cutter of the above aspect, the harvester has all the beneficial effects of the above double-moving blade cutter, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0055] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0056] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0057] Combine the following Figures 1 to 15 , describing an embodiment of a double-moving knife cutter and a harvester provided by the utility model.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, on the one hand, an embodiment of the utility model provides a double movable knife cutter 100, which includes a double movable knife assembly 10, a first drive mechanism 20, a second drive mechanism 30 and a reel-pulling rotary shaft 41. The double movable knife assembly 10 includes a first movable knife group 11 and a second movable knife group 12. The first drive mechanism 20 includes a first drive assembly 21 and a first crank assembly 22, and the first drive assembly 21 is transmission-connected to the first movable knife group 11 through the first crank assembly 22. The second drive mechanism 30 includes a second drive assembly 31 and a second crank assembly 32, and the second drive assembly 31 is transmission-connected to the second movable knife group 12 through the second crank assembly 32. One end of the reel-pulling rotary shaft 41 is transmission-connected to the first drive assembly 21, and the other end of the reel-pulling rotary shaft 41 is transmission-connected to the second drive assembly 31, so that the first drive assembly 21 and the second drive assembly 31 operate synchronously.

[0059] The first movable knife group 11 and the second movable knife group 12 can be in contact or fitted in the up-down direction, and the first movable knife group 11 and the second movable knife group 12 can be driven to reciprocate in the left-right direction to cut the rice plants. That is, the first movable knife group 11 and the second movable knife group 12 can be extended in the left-right direction (such as the axial direction of the rice-moving rotary shaft 41, that is, the length direction).

[0060] The first driving mechanism 20 and the second driving mechanism 30 may be arranged close to each other in the left-right direction, or may be arranged spaced apart or opposite to each other in the left-right direction.

[0061] The first drive assembly 21 can convert the rotational motion into a reciprocating telescopic motion through the first crank assembly 22, and the second drive assembly 31 can also convert the rotational motion into a reciprocating telescopic motion through the second crank assembly 32. Since the first drive assembly 21 and the second drive assembly 31 are synchronously connected through the reed-plowing rotary shaft 41, the first crank assembly 22 and the second crank assembly 32 can be made to move synchronously in the same direction or synchronously in opposite directions by adjusting the configuration. Combined with the difference in the structure and installation position of the first crank assembly 22 and the second crank assembly 32, the synchronous movement of the first crank assembly 22 and the second crank assembly 32 in the same direction or synchronous movement in opposite directions can realize the synchronous opposite cutting movement of the first movable knife group 11 and the second movable knife group 12.

[0062] The first movable knife group 11 generates inertia force and impact load during the cutting movement, and the second movable knife group 12 also generates reverse inertia force and reverse impact load during the synchronous reverse cutting movement. Since the two inertia forces and the two impact loads in opposite directions at least partially offset each other, the inertia force and impact load generated by the double movable knife assembly 10 during the reciprocating cutting movement are greatly reduced. Even when the two reverse inertia forces are equal or approximately equal in magnitude, and the two reverse impact loads are equal or approximately equal in magnitude, the double movable knife assembly 10 will not generate inertia force and impact load during the reciprocating cutting movement or will generate almost zero inertia force and impact load.

[0063] In this way, the double movable blade assembly 10 can reach a dynamic balance state or a state close to a dynamic balance state during the reciprocating cutting motion, so that the first movable blade assembly 11 and the second movable blade assembly 12 can offset each other's impulses and reduce the overall vibration, and have a good coordination state, thereby achieving the effect of offsetting the load impulse and reducing the vibration amplitude, so as to avoid resonance with other moving parts of the whole machine. This is conducive to improving the use experience and service life of the double movable blade cutter 100, and improving the stability of the whole machine.

[0064] In some embodiments, Figure 2As shown, the first drive assembly 21 and the second drive assembly 31 are spaced apart along the axial direction of the reel rotating shaft 41. Along the axial direction of the reel rotating shaft 41, one end of the first drive assembly 21 away from the second drive mechanism 30 is transmission-connected to one end of the reel rotating shaft 41, and one end of the second drive assembly 31 away from the first drive mechanism 20 is transmission-connected to the other end of the reel rotating shaft 41.

[0065] Reference Figure 1 and Figure 4 The double-movable blade cutter 100 further includes a cutting table 50, and along the axial direction (such as the left-right direction) of the reel rotating shaft 41, the left and right ends of the reel rotating shaft 41 are respectively arranged close to the left and right sides of the cutting table 50. Exemplarily, the right end of the first driving assembly 21 is arranged close to the right side of the cutting table 50, and the left end of the second driving assembly 31 is arranged close to the left side of the cutting table 50.

[0066] In this way, the left end of the reel rotating shaft 41 and the left end of the second driving member can be connected by transmission on the left side of the cutting table 50. The right end of the reel rotating shaft 41 and the right end of the first driving member can be connected by transmission on the right side of the cutting table 50, which facilitates the assembly operation of the transmission structure.

[0067] Alternatively, the first driving assembly 21 may be installed close to the left side of the cutting table 50, and the second driving assembly may be installed close to the right side of the cutting table, which is not limited to this.

[0068] like Figures 1 to 4 As shown, a accommodating cavity is provided on the front side of the cutting table body 50, and the double-moving blade cutter 100 also includes a cutting table auger 61, which is installed in the accommodating cavity, and the rotating cutting table auger 61 is used to gather the cut rice plants to the feed port at the rear of the accommodating cavity, so that the cut rice plants can be transported backward through the feed port.

[0069] like Figure 2 and Figure 4 As shown, the double-moving blade cutter 100 further includes a reel 62, which is arranged close to the accommodating chamber, such as being arranged at an upper position in front of the cutting platform auger 61. The rotating reel 62 is used to gather the front crops into the accommodating chamber, and then the sheared crops are gathered to the feed inlet by the cutting platform auger 61 and transported backward.

[0070] Reference Figures 3 to 5The reel 62 is assembled and connected to the cutting table body 50 through a connecting frame. The reel 62 is rotatably mounted on the connecting frame, and the other end of the connecting frame is rotatably connected to the cutting table body 50, so that the connecting frame can rotate relative to the cutting table body 50 around an axis parallel to the left and right direction, thereby adjusting the height position of the reel 62 and the receiving cavity. In the working state, the height of the reel 62 is lowered so that the reel 62 can smoothly collect the crops into the receiving cavity. The height of the reel 62 can also be raised so that there is sufficient space under the reel 62 to facilitate the cleaning and maintenance of the receiving cavity.

[0071] It should be noted that when the connecting frame is rotatably connected to the cutting table body 50, it must be hingedly assembled with the cutting table body 50 through structures such as a hinge seat and a hinge shaft. Based on this, the reel rotating shaft 41 can be assembled at the hinge through a bearing so that the axis of the reel rotating shaft 41 and the rotating axis of the connecting frame are approximately coincident or close to each other. That is, the assembly of the reel rotating shaft 41 can be completed using existing structural components, and the structure is simple.

[0072] In some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, the first transmission wheel 42 and the second transmission wheel 43 are transmission-connected at both ends of the reel rotating shaft 41. The first drive assembly 21 includes a first drive shaft 211 and a first drive wheel 212. Along the axial direction of the reel rotating shaft 41, the end of the first drive shaft 211 away from the second drive mechanism 30 is provided with a first drive wheel 212, and the first transmission wheel 42 is transmission-connected with the first drive wheel 212. The second drive assembly 31 includes a second drive shaft 311 and a second drive wheel 312. Along the axial direction of the reel rotating shaft 41, the end of the second drive shaft 311 away from the first drive mechanism 20 is transmission-connected with the second drive wheel 312, and the second transmission wheel 43 is transmission-connected with the second drive wheel 312, so that the first drive wheel 212 and the second drive wheel 312 rotate synchronously.

[0073] Through the transmission connection between the first transmission wheel 42 and the first drive wheel 212 , and the transmission connection between the second transmission wheel 43 and the second drive wheel 312 , the installation positions of the first drive shaft 211 and the second drive shaft 311 can be flexibly arranged in the radial direction of the reel rotating shaft 41 .

[0074] Exemplarily, the transmission connection between the first transmission wheel 42 and the first drive wheel 212 can be a transmission connection by gear meshing, a transmission connection by a sprocket structure, or a transmission connection by using a synchronous pulley, so as to avoid slippage between the first transmission wheel 42 and the first drive wheel 212.

[0075] Correspondingly, the transmission wheel connection between the second transmission wheel 43 and the second drive wheel 312 can be a transmission connection of gear meshing, a transmission connection of a sprocket structure, or a transmission connection using a synchronous pulley, so as to avoid slipping between the second transmission wheel 43 and the second drive wheel 312, and make the first drive wheel 212 and the second drive wheel 312 rotate synchronously, so as to make the first crank assembly 22 and the second crank assembly 32 operate synchronously.

[0076] In some embodiments, Figures 2 to 4 As shown, along the axial direction of the reel rotating shaft 41 , at least one of an end of the first driving shaft 211 close to the second driving mechanism 30 and an end of the second driving shaft 311 close to the first driving mechanism 20 is configured as a power input end.

[0077] Since the two ends of the first drive assembly 21 and the second drive assembly 31 that are far away from each other are synchronously connected through the reed-pulling rotating shaft 41, at least one end of the first drive assembly 21 and the second drive assembly 31 that are close to each other can be set as a power input end, so that the double movable knife assembly 10 can be driven to rotate synchronously in the opposite direction by the power of the harvester through the first drive mechanism 20, the second drive mechanism 30 and the reed-pulling transmission mechanism 40.

[0078] like Figures 2 to 5 As shown, the cutting table body 50 includes a harvesting part provided with a receiving cavity and a connecting part connected to the rear opening of the receiving cavity. Taking the axial direction of the reed-pulling rotating shaft 41 as an example, the width dimension of the harvesting part in the left-right direction is greater than the width dimension of the connecting part in the left-right direction. On the rear side of the harvesting part, the first drive assembly 21 is arranged on the right side of the connecting part, and the second drive assembly 31 is arranged on the left side of the connecting part, the first drive wheel 212 is arranged close to the right side of the harvesting part, and the second drive wheel 312 is arranged close to the left side of the harvesting part.

[0079] The corresponding first transmission wheel 42 is arranged close to the right side of the harvesting part. The second transmission wheel 43 is synchronously connected with the second driving wheel 312 through a chain or a synchronous belt.

[0080] Exemplarily, the second crank assembly 32 and the first crank assembly 22 are respectively arranged on the left and right sides of the harvesting section. That is, the first crank assembly 22 is used to transmit the power at the first drive wheel 212 to the right front of the harvesting section, and convert the rotational power into a left-right reciprocating power, so as to drive the first movable knife group 11 to reciprocate in the left-right direction for cutting the rice plants. The second crank assembly 32 is used to transmit the power at the second drive wheel 312 to the left front of the harvesting section, and convert the rotational power into a left-right reciprocating power, so as to drive the second movable knife group 12 to reciprocate in the left-right direction, and make the first movable knife group 11 and the second movable knife group 12 synchronously cut in the opposite direction in the left-right direction, so as to reduce the inertia force and impact load of the double movable knife combination 10 while cutting the rice plants.

[0081] Furthermore, by arranging the second drive mechanism 30 and the first drive mechanism 20 on the left and right sides of the cutting table 50 respectively, the second movable knife group 12 and the first movable knife group 11 are driven to synchronously perform opposite cutting movements, so that the two sets of drive components of the double movable knife assembly 10 are relatively evenly distributed on the left and right sides of the cutting table 50. This solves the problem of changing from single-side transmission to double-side transmission, saves space and cost, and is conducive to improving the stability of the structure, thereby improving the use experience and service life of the equipment.

[0082] Alternatively, the first drive mechanism 20 may be disposed on the left side of the cutting table 50, and the second drive mechanism 30 may be disposed close to the right side of the cutting table 50. The first drive shaft 211 and the second drive shaft 311 are disposed parallel or approximately parallel to the reel rotating shaft 41. This is not limited thereto.

[0083] like Figure 2 and Figure 5 As shown, the power device of the harvester drives the first drive assembly 21 and / or the second drive assembly 31 through the belt transmission structure on the left and right sides of the connection part, which has the characteristics of simple structure and high reliability. Exemplarily, one of the first drive assembly 21 and the second drive assembly 31 can be set as a power input end to drive the double movable blade assembly 10 to cut. Alternatively, the first drive assembly 21 and the second drive assembly 31 can also be set as power input ends at the same time, which can also drive the double movable blade assembly 10 to cut.

[0084] In some embodiments, Figure 2 and Figure 4 As shown, the second driving assembly 31 includes a second driving wheel 313 , and one end of the second driving shaft 311 close to the first driving mechanism 20 is drivingly connected to the second driving wheel 313 , and the second driving wheel 313 is configured as a power input end.

[0085] In this way, by setting the second driving wheel 313 as the power input end, the second driving wheel 312 and the first driving wheel 212 on the left and right sides of the cutting table 50 can be synchronously rotated through the transmission connection of the second driving shaft 311, the second driving wheel 312, the second transmission wheel 43, the reel rotating shaft 41, the first transmission wheel 42 and the first driving wheel 212, so as to drive the second moving knife group 12 and the first moving knife group 11 to synchronously cut in the opposite direction.

[0086] In some embodiments, Figure 2 , Figure 4 and Figure 6As shown, the first drive assembly 21 includes a first driving wheel 213 and an auger driving wheel 214. The end of the first driving shaft 211 close to the second driving mechanism 30 is connected to the first driving wheel 213, and the first driving wheel 213 is configured as a power input end. The end of the first driving shaft 211 away from the second driving mechanism 30 is connected to the auger driving wheel 214, which is used to drive the cutting platform auger 61 to rotate.

[0087] By setting a first driving wheel 213 as a power input end at one end of the first driving shaft 211, the second driving wheel 312 and the first driving wheel 212 on the left and right sides of the cutting table 50 can be synchronously rotated through the transmission connection of the first driving assembly 21, the first transmission wheel 42, the reel rotating shaft 41, the second transmission wheel 43 and the second driving wheel 312, thereby driving the second moving knife group 12 and the first moving knife group 11 to synchronously cut in the opposite direction. On this basis, by transmission connection with the auger driving wheel 214 at one end of the first driving shaft 211 away from the first driving wheel 213, the first driving assembly 21 can also drive the cutting table auger 61 to rotate.

[0088] Based on this, Figure 2 and Figure 6 As shown, the first driving assembly 21 further includes a driving bearing 215 , and the first driving wheel 212 is connected to the first driving shaft 211 via the driving bearing 215 .

[0089] At one end of the first drive shaft 211 away from the first driving wheel 213, the first drive wheel 212 is connected to the end of the first drive shaft 211 through a drive bearing 215, which is used for positioning and installing the first drive wheel 212, but the drive bearing 215 avoids the transmission connection between the first drive shaft 211 and the first drive wheel 212. By setting a non-transmission connection between the first drive wheel 212 and the first drive shaft 211, it is possible to avoid the first drive shaft 211 driving the first moving knife group 11 and the cutting table auger 61 to rotate at the same time, so as to achieve differential transmission between the double moving knife assembly 10 and the cutting table auger 61. At this time, the first drive shaft 211 has a smaller transmission load, which is conducive to improving the overall stability of the first drive assembly 21.

[0090] It should be noted that, when the first driving wheel 212 is connected and installed with the first driving shaft 211 through the driving bearing 215, the second driving wheel 313 can be set at the right end of the second driving shaft 311. At this time, the power transmitted by the first driving wheel 213 is used to drive the cutting table auger 61 to rotate via the first driving shaft 211 and the auger driving wheel 214, and the power transmitted by the second driving wheel 313 is used to drive the double-moving knife assembly 10 to synchronously cut in the opposite direction via the second transmission shaft, the second driving wheel 312, the reel-moving rotary shaft 41 and the first driving wheel 212, so as to avoid a large transmission load at the second driving shaft 311, so as to achieve a differential connection between the double-moving knife assembly 10 and the cutting table auger 61.

[0091] Furthermore, when the first driving wheel 213 and the second driving wheel 313 are both configured as power input ends, the non-transmission connection between the first driving wheel 212 and the first driving shaft 211 can avoid tooth jamming or slipping caused by asynchronous rotation between the first driving wheel 213 and the second driving wheel 313.

[0092] In some other embodiments, the first driving wheel 212 may be connected to the first driving shaft 211 in a transmission connection. For example, the first driving wheel 212 may be connected to the end of the first driving shaft 211 away from the first driving wheel 213 in a transmission connection, so that the first driving shaft 211 can simultaneously drive the double movable blade assembly 10 and the cutting table auger 61 to operate. At this time, the power input end may be synchronously set at the first driving assembly 21, that is, the first driving wheel 213 and the second driving wheel 313 may be set as the power input end, so that the input power is more evenly distributed on the left and right sides of the cutting table body 50. Alternatively, only the first driving wheel 213 or the second driving wheel 313 may be set as the power input end, which has a simple structure.

[0093] For example, Figure 6 As shown, the right end of the first drive shaft 211 is positioned and connected to the rear side of the harvesting part in the cutting table body 50 through a bearing seat, and at the end of the first drive shaft 211 extending to the right, the auger drive wheel 214 and the first drive wheel 212 are connected from left to right in sequence. The difference is that the auger drive wheel 214 and the first drive shaft 211 are connected by transmission, so as to avoid the rotation slip between the two. The first drive wheel 212 is connected to the first drive shaft 211 through a drive bearing 215, that is, the first drive wheel 212 can rotate more flexibly than the first drive shaft 211.

[0094] In some embodiments, Figure 2 , Figure 6 and Figure 7 As shown, the first crank assembly 22 includes a first eccentric 221, a first connecting rod 222 and a first rocker 223. The first driving wheel 212 is connected to the first eccentric 221 at a position radially away from the axis, and the first eccentric 221 is connected to the first moving knife assembly 11 through the first connecting rod 222 and the first rocker 223.

[0095] Through the rotational connection between the first eccentric member 221 and the first connecting rod 222, the rotational power of the first driving wheel 212 can be converted into the power of the first connecting rod 222 to reciprocate and extend approximately in the front-to-back direction (i.e., perpendicular to the axial direction of the first transmission shaft). On this basis, the middle part of the first rocker arm member 223 can be rotatably installed near the right front end of the cutting table body 50, one end of the first rocker arm member 223 is rotationally connected to the first connecting rod 222, and the other end of the first rocker arm member 223 is rotationally connected to the first movable knife group 11, so that the power of the first connecting rod 222 to reciprocate and extend approximately in the front-to-back direction is converted into the power to reciprocate and extend approximately in the left-to-right direction (i.e., parallel to the axial direction of the first transmission shaft) through the first rocker arm member 223, thereby driving the first movable knife group 11 to reciprocate in the left-to-right direction.

[0096] Correspondingly, such as Figure 2 , Figure 8 and Fig. 9 As shown, the second crank assembly 32 includes a second eccentric 321, a second connecting rod 322 and a second rocker 323. The second drive wheel 312 is connected to the second eccentric 321 at a position radially away from the axis, and the second eccentric 321 is connected to the second movable knife assembly 12 through the second connecting rod 322 and the second rocker 323.

[0097] Through the rotational connection between the second eccentric member 321 and the second connecting rod 322, the rotational power of the second drive shaft 311 can be converted into the power of the second connecting rod 322 to reciprocate and extend approximately in the front-to-back direction (i.e., perpendicular to the axial direction of the second transmission shaft). On this basis, the middle part of the second rocker arm member 323 can be rotatably installed near the left front end of the cutting table body 50, one end of the second rocker arm member 323 is rotationally connected to the second connecting rod 322, and the other two ends of the second rocker arm member 323 are rotationally connected to the second movable knife group 12, so that the power of the second connecting rod 322 to reciprocate and extend approximately in the front-to-back direction is converted into the power to reciprocate and extend approximately in the left-to-right direction (i.e., parallel to the axial direction of the first transmission shaft) through the second rocker arm member 323, thereby driving the second movable knife group 12 to reciprocate in the left-to-right direction.

[0098] In this way, the first driving wheel 212 drives the first moving knife group 11 to reciprocate in the left and right directions through the first eccentric member 221, the first connecting rod 222 and the first rocker member 223, and the second driving wheel 312 drives the second moving knife group 12 to reciprocate in the left and right directions through the second eccentric member 321, the second connecting rod 322 and the second rocker member 323. Since the first driving wheel 212 rotates synchronously with the second driving wheel 312, the first crank assembly 22 and the second crank assembly 32 can be configured on the left and right sides of the cutting table 50 as two sets of components that are symmetrically arranged on the left and right sides, so that the first moving knife group 11 and the second moving knife group 12 driven by the first crank assembly 22 and the second crank assembly 32 synchronously cut in opposite directions along the left and right directions (i.e., the axial direction of the reel rotating shaft 41), which is beneficial to reduce or offset the inertia force and impact load of the double moving knife assembly 10.

[0099] It should be noted that if Fig.10 As shown, a joint bearing is provided at the front end of the first connecting rod 222 near the first rocker arm 223, and the first connecting rod 222 is rotatably connected to one end of the first rocker arm 223 through the joint bearing. Through the provision of the joint bearing, the first connecting rod 222 has a larger swing range in the process of reciprocating telescopic movement in the front-back direction compared with the first rocker arm 223, thereby avoiding the damage of components caused by large local stress between the first connecting rod 222 and the first rocker arm 223 during the transmission process.

[0100] That is to say, on the right side of the cutting table body 50, at least one of the first eccentric member 221 and the first connecting rod 222, the first connecting rod 222 and the first rocker arm member 223, the first rocker arm member 223 and the cutting table body 50, and the first rocker arm member 223 and the first movable knife group 11 can be connected by a joint bearing or a bearing, which has a small friction force and is convenient for assembly and debugging of parts.

[0101] Correspondingly, on the left side of the cutting table body 50, at least one of the second eccentric member 321 and the second connecting rod 322, the second connecting rod 322 and the second rocker arm member 323, the second rocker arm member 323 and the cutting table body 50, and the second rocker arm member 323 and the second movable knife group 12 can also be connected by a joint bearing or a bearing, which has a small friction force and is convenient for assembly and debugging of parts.

[0102] Correspondingly, the first rocker arm 223 and the first moving knife assembly 11 may also be connected via a joint bearing. The first connecting rod 222 and the first eccentric member 221 may also be connected via a joint bearing or a bearing, so as to facilitate assembly and debugging of parts.

[0103] On the left side of the cutting table 50 , at least one of the second connecting rod 322 and the second rocker arm 323 , the second connecting rod 322 and the second eccentric member 321 , and the second rocker arm 323 and the second movable knife assembly 12 can also be rotatably connected using a joint bearing or a bearing.

[0104] It should be noted that if Figure 6 As shown, a structural wheel can be arranged between the first driving wheel 212 and the first eccentric member 221 , and the structural wheel is transmission-connected to the first driving wheel 212 . For example, the first driving wheel 212 and the structural wheel can be connected by a plurality of axially arranged screws to improve the overall structural strength of the first driving wheel 212 .

[0105] For example, the structural wheel and the first driving wheel 212 can be coaxially arranged, and the first eccentric 221 is fixedly connected to the structural wheel at a position away from the axis, and then the rear end of the first connecting rod 222 is rotationally connected to the first eccentric 221, and its rotation axis is parallel to the axis of the first driving shaft 211.

[0106] Correspondingly, such as Figure 8 As shown, a structural wheel may also be provided between the second driving wheel 312 and the second eccentric member 321 to improve the overall structural strength of the second driving wheel 312 .

[0107] In some other embodiments, such as Fig.11 As shown, the first crank assembly 22 may also include a first direction-changing shaft 224, a first eccentric 221 and a first connecting rod 222. The first direction-changing shaft 224 is arranged vertically or approximately vertically with the first drive shaft 211, and the first drive wheel 212 is meshedly connected with the rear end of the first direction-changing shaft 224 to convert the rotation of the first drive wheel 212 around the left-right direction into the rotation of the first direction-changing shaft 224 around the front-back direction. The front end of the first direction-changing shaft 224 is connected to the first movable knife driving wheel, and the first movable knife driving wheel can rotate around the front-back direction (i.e., the axial direction of the first direction-changing shaft 224). The first eccentric 221 is connected to the first movable knife driving wheel at a position away from the axis thereof, one end of the first connecting rod 222 is rotatably connected with the first eccentric 221, and the other end of the first connecting rod 222 is rotatably connected with the first movable knife group 11, so that the first movable knife driving wheel can drive the first movable knife group 11 to reciprocate in the left-right direction through the first connecting rod 222 during the rotation process.

[0108] Correspondingly, the second crank assembly 32 may also include a second direction-changing shaft, a second eccentric 321 and a second connecting rod 322. The second direction-changing shaft is arranged vertically or approximately vertically with the second drive shaft 311, and the second drive wheel 312 is meshedly connected with the rear end of the second direction-changing shaft to convert the rotation of the second drive wheel 312 around the left-right direction into the rotation of the second direction-changing shaft around the front-back direction. The front end of the second direction-changing shaft is connected to the second movable knife drive wheel, which can rotate around the front-back direction (i.e., the axial direction of the first direction-changing shaft 224), the second eccentric 321 is connected to the second movable knife drive wheel at a position away from its axis, one end of the second connecting rod 322 is rotationally connected with the second eccentric 321, and the other end of the second connecting rod 322 is rotationally connected with the second movable knife group 12, so that the second movable knife drive wheel can drive the second movable knife group 12 to reciprocate in the left-right direction through the second connecting rod 322 during the rotation process.

[0109] Since the first driving wheel 212 and the second driving wheel 312 are configured to rotate synchronously, by adjusting the first crank assembly 22 and the second crank assembly 32, the first movable knife assembly 11 and the second movable knife assembly 12 can also make synchronous opposite cutting movements in the left and right directions.

[0110] In some embodiments, Figure 2 and Fig.12 As shown, along the axial direction of the weeding rotary shaft 41, an auger transmission wheel 63 is provided at one end of the cutter auger 61 close to the first drive shaft 211, and the auger transmission wheel 63 is transmission connected to the cutter auger 61, and the auger transmission wheel 63 is transmission connected to the auger drive wheel 214, so that the auger drive wheel 214 can drive the cutter auger 61 to rotate by chain drive, belt drive, synchronous belt drive or gear meshing.

[0111] In some embodiments, Figure 2 and Fig.13 As shown, the reel transmission mechanism 40 further includes a reel driving wheel 44 and a reel bearing 45, and the reel driving wheel 44 is connected to one end of the reel rotating shaft 41 through the reel bearing 45. That is, there is no transmission connection between the reel driving wheel 44 and the reel rotating shaft 41, and the reel driving wheel 44 is used to drive the reel wheel 62 to rotate.

[0112] For example, continue to refer to Figure 2 , Fig.12 and Fig.13, one end of the harvesting platform auger 61 is also connected to the first reed transmission wheel 64. The reed transmission mechanism 40 also includes a second reed transmission wheel 46, which is transmission-connected to the reed driving wheel 44, and the second reed transmission wheel 46 is also transmission-connected to the first reed transmission wheel 64. So that the auger driving wheel can drive the harvesting platform auger 61 and the reed wheel 62 to rotate at the same time. The reed rotating shaft 41 is connected to the reed driving wheel 44 and the second reed transmission wheel 46 via the reed bearing 45, so as to avoid the harvesting platform auger 61 interfering with the rotation of the reed rotating shaft 41 in the process of driving the reed wheel 62 to rotate.

[0113] In some other embodiments, the reel bearing 45, the first reel transmission wheel 64 and the reel driving wheel 44 may not be provided. The reel rotating shaft 41 is connected to the reel driving wheel 44 in a transmission manner to drive the reel wheel 62 to rotate, and the structure is simple.

[0114] In some embodiments, Fig.14 and Fig.15 As shown, the first moving knife group 11 and the second moving knife group 12 are respectively provided with a plurality of blades, and the first moving knife group 11 and the second moving knife group 12 can be assembled close to each other in the up-down direction. So that the first moving knife group 11 and the second moving knife group 12 are at least partially overlapped in the length direction. In this way, when the first moving knife group 11 and the second moving knife group 12 are separated from each other to the maximum distance in the left-right direction, at least some blades (such as three to five blades) of the first moving knife group 11 and the second moving knife group 12 can be overlapped, thereby avoiding the existence of a blind cutting area between some double moving knife assemblies 10 where the rice plants cannot be cut.

[0115] In some embodiments, continue to refer to Fig.14 and Fig.15 The double movable knife assembly 10 further includes a first blade guard 13 and a second blade guard 14. The first blade guard 13 is arranged close to the first movable knife assembly 11, and a plurality of first blade guards 13 are arranged at intervals along the length direction of the first movable knife assembly 11. The second blade guard 14 is arranged close to the second movable knife assembly 12, and a plurality of second blade guards 14 are arranged at intervals along the length direction of the second movable knife assembly 12.

[0116] Taking the example of the first movable knife group 11 being close to and arranged above the second movable knife group 12, the first blade guard 13 is arranged on the upper side of the first movable knife group 11, and the second blade guard 14 is arranged on the lower side of the second movable knife group 12. When the first movable knife group 11 performs reciprocating cutting motion along the left and right directions, the multiple blades of the first movable knife group 11 reciprocate compared with the multiple first blade guards 13 to clamp and cut the crops between the two. Correspondingly, when the second movable knife group 12 performs reciprocating cutting motion along the left and right directions, the multiple blades of the second movable knife group 12 reciprocate compared with the multiple second blade guards 14 to clamp and cut the crops between the two. That is, the blade guard protects the movable knife group while allowing the movable knife group to reciprocate to complete the cutting action, which has higher reliability.

[0117] In actual application, the harvester transmits power to the first driving wheel 213 and the second driving wheel 313 to make the first driving wheel 213 and the second driving wheel 313 rotate rapidly. The first driving wheel 213 drives the harvesting platform auger 61 and the reed wheel 62 to rotate via the first driving shaft 211, the auger driving wheel 214, the auger transmission wheel 63, the first reed transmission wheel 64, the second reed transmission wheel 46, and the reed driving wheel 44.

[0118] The second driving wheel 313 makes the first driving wheel 212 and the second driving wheel 312 rotate synchronously through the second driving shaft 311, the second driving wheel 312, the second transmission wheel 43, the reel rotating shaft 41, the first transmission wheel 42, and the first driving wheel 212. Among them, the first driving wheel 212 and the first transmission wheel 42, and the second driving wheel 312 and the second transmission wheel 43 are driven by sprockets to avoid slippage. On this basis, after adjustment, the first crank assembly 22 and the second crank assembly 32 on both sides of the cutting table body 50 are synchronized to drive the first moving knife group 11 and the second moving knife group 12 on the front side of the cutting table body 50 to synchronize the reverse cutting movement, so that the inertial force and impact load generated by the first moving knife group 11 and the second moving knife group 12 in the reciprocating cutting process can weaken or offset each other, thereby greatly reducing the inertial force and impact load generated by the double moving knife assembly 10 during the reciprocating cutting process.

[0119] On the other hand, an embodiment of the present utility model further provides a harvester, comprising the double-moving blade cutter 100 of any one of the above aspects.

[0120] Since the harvester includes the double-moving blade cutter 100 in the above aspect, the harvester has all the beneficial effects of the double-moving blade cutter 100, which will not be described in detail here.

[0121] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
