Description

Technical Field

[0001] This invention relates to the field of mechanical engineering technology, and in particular to a connecting device and a drying machine. Background Technology

[0002] In recent years, to improve harvesting efficiency, combine harvesters have been widely used to harvest corn or hay. After harvesting, corn stalks or hay are generally piled in furrows to dry. The stalks on the surface dry easily, while those at the bottom, being covered, are difficult to dry. If they are directly picked up and baled, they will rot. To avoid rot, they must be turned over and dried. Thus, turners are widely used. In existing technology, the turner is connected to the tractor at three points using a pin-type connection. The power source and hydraulic source of the turner are also connected through the tractor's output. The above method has the following problems:

[0003] 1. The length of the connecting support rod between the turner and the tractor is not adjustable. If the hydraulic cylinders on both sides of the turner are not fully extended or retracted, or if the finger rods on both sides are not on an uneven ground, the working effect of the turner will be affected.

[0004] 2. The tractor's three-point coupling is a pin-type connection (with a large gap). After the turner is laid flat, there will be a phenomenon of left and right side offset and front and back offset. The resistance to the rotation of the finger rods on both sides is uneven. When swinging or vibration occurs, the torque (stress) cannot be released, which will cause the support rod of constant length to break or damage the turner, making it unable to work. Summary of the Invention

[0005] To address the technical problem in existing technologies where the length of the support rod between the drying machine and the tractor is not adjustable, leading to the support rod breaking under torsional force or vibration, this invention provides a connecting device and a drying machine, thus solving the aforementioned technical problem. The technical solution of this invention is as follows:

[0006] A connecting device for connecting a drying machine and a tractor, and for adjusting the position between the drying machine and the tractor, includes: a connecting assembly comprising a first connector and a second connector, the first connector being connected to the tractor and the second connector being connected to the drying machine, the adjacent ends of the first connector and the second connector being slidably interlocked, and the first connector and the second connector being limited by a limiting member after interlocking; and at least one vibration damping assembly disposed near the interlocking point of the first connector and the second connector, the vibration damping assembly being disposed on the first connector and / or the second connector.

[0007] According to one embodiment of the present invention, the diameter of the first connector is smaller than the diameter of the second connector, a plurality of adjustment holes are formed on the side wall of the first connector along the axial direction, and a limiting hole corresponding to the adjustment holes is formed on the second connector. The limiting member passes through the limiting hole and the adjustment hole to limit the first connector and the second connector.

[0008] According to one embodiment of the present invention, the adjusting hole is configured as an oblong hole so that the first connector can move relative to the limiting member.

[0009] According to one embodiment of the present invention, the vibration damping assembly includes: two clamping members, the clamping portions of the two clamping members being arranged facing each other to form a clamping channel, and a second connecting member passing through the clamping channel; at least one fastener, the fastener performing a fastening action on the two clamping members; and an elastic member, the elastic member being sleeved on the fastener.

[0010] According to one embodiment of the present invention, a carrier base plate is provided on the second connector, the carrier base plate and the clamping member are correspondingly provided, a vibration damping member is provided between the carrier base plate and the clamping member, and the fastener connects the carrier base plate, the vibration damping member and the clamping member together.

[0011] According to one embodiment of the present invention, the clamping part is adapted to the outer wall of the second connector, and the clamping part is made of nitrile rubber.

[0012] A drying machine includes the aforementioned connecting device.

[0013] According to one embodiment of the present invention, the drying machine further includes a connecting frame and a lifting arm. One side of the connecting frame is connected to the tractor via a connector, and one end of the connecting frame is connected to the lifting arm via a connector module. A support member is connected to the lifting arm.

[0014] According to one embodiment of the present invention, the plug-in module includes: a limiting plug, which passes through a socket hole on the connecting frame and the lifting arm to connect the connecting frame and the lifting arm, a limiting groove is formed on the limiting plug, and the end of the lifting arm extends into the limiting groove to limit the limiting plug; and a pulling member, which is connected to the limiting plug via a connecting plate, and the pulling member is connected to the oil cylinder dustproof locking cover of the turning machine via a rope.

[0015] According to one embodiment of the present invention, a connecting frame is provided with a connecting ball seat, the ball in the connecting ball seat is rotatably engaged with the tractor, and tube frames are also formed on both sides of the connecting frame, with slots formed on the tube frames, and one end of the protective member extends into the slot.

[0016] Based on the above technical solution, the technical effects that the present invention can achieve are as follows:

[0017] 1. The connecting device of this application is disposed between the drying machine and the tractor. The first connecting member and the second connecting member are respectively connected to the drying machine and the tractor. The adjacent ends of the first connecting member and the second connecting member are slidably connected. After the first connecting member and the second connecting member are connected, they are limited by the limiting member. A vibration damping component is provided at the connection point of the first connecting member and the second connecting member. Compared with the prior art where the length of the support rod between the drying machine and the tractor is not adjustable, which causes the support rod to break after being subjected to torsion or vibration, this application divides the connecting component into two parts, which can be adapted to the distance adjustment between the drying machine and the tractor as needed. The vibration damping component absorbs the torsional or vibration force when the position of the connecting component is adjusted, thereby preventing the connecting component from breaking and ensuring the operation of the machine.

[0018] 2. The first connecting member of this application has a plurality of adjustment holes formed on its side wall along the axial direction, and the second connecting member has a limiting hole corresponding to the adjustment holes. The limiting member passes through the limiting hole and the adjustment hole to limit the connecting member and the second connecting member, so that the drying machine and the tractor can perform length adjustment and are also easy to disassemble and separate.

[0019] 3. The vibration damping component of this application includes two clamping members, at least one fastener, and an elastic member. The clamping portions of the two clamping members are arranged facing each other to form a clamping channel. A second connecting member passes through the clamping channel. The fastener performs a fastening action on the two clamping members. The elastic member is sleeved on the fastener. The vibration generated by adjusting the position on the connecting component will be absorbed by the elastic member, thereby preventing the connecting device from breaking.

[0020] 4. The plug-in module for connecting frame and lifting arm of this application includes a limiting plug and a pulling member. A limiting groove is formed on the limiting plug. The end of the lifting arm extends into the limiting groove to limit the limiting plug, thereby preventing the limiting plug from moving and thus avoiding unnecessary movement between the connecting frame and the lifting arm. In addition, the pulling member is connected to the limiting plug by means of a connecting plate. The pulling member is connected by a rope cylinder dustproof locking cover for pulling up the dustproof locking cover of the front cylinder when the two wing fingers of the turning machine are not in operation.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0037] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0038] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0039] like Figure 1-11 As shown, a connecting device in this embodiment is used to connect a drying machine and a tractor, and can adjust the position between the drying machine and the tractor. The connecting device includes a connecting component 1 and at least one vibration damping component 2. The connecting component 1 includes a first connecting member 11 and a second connecting member 12. The first connecting member 11 is connected to the tractor, and the second connecting member 12 is connected to the drying machine. The adjacent ends of the first connecting member 11 and the second connecting member 12 are slidably inserted and connected, and the first connecting member 11 and the second connecting member 12 are limited by a limiting member 3 after insertion. The vibration damping component 2 is disposed near the insertion point of the first connecting member 11 and the second connecting member 12, and is disposed on the first connecting member 11 and / or the second connecting member 12.

[0040] In this embodiment, the first connecting member 11 and the second connecting member 12 are used to connect the drying machine and the tractor. When the drying machine and the tractor need to be adjusted, the limiting member 3 releases the limiting of the first connecting member 11 and the second connecting member 12. The first connecting member 11 and the second connecting member 12 move relative to each other and are then limited again. In addition, the torsion or vibration generated by the movable connection between the first connecting member 11 and the second connecting member 12 is absorbed by the vibration damping component 2, thereby avoiding the first connecting member 11 and the second connecting member 12 from breaking due to mechanical vibration. The above method solves the problem in the prior art that the length of the overall support rod between the drying machine and the tractor is not adjustable, which leads to the support rod breaking after being subjected to torsion or mechanical vibration.

[0041] In this embodiment, the position between the first connector 11 and the second connector 12 is adjustable. Specifically, the diameter of the first connector 11 is smaller than the diameter of the second connector 12. A plurality of adjustment holes 111 are formed on the side wall of the first connector 11 along the axial direction. The second connector 12 is formed with limiting holes 121 corresponding to the adjustment holes 111. The limiting member 3 passes through the limiting hole 121 and the adjustment hole 111 to limit the first connector 11 and the second connector 12. In this embodiment, the limiting member 3 is set as a limiting bolt. When it is necessary to adjust the position between the first connector 11 and the second connector 12, the limiting bolt releases the limiting of the first connector 11 and the second connector 12. After the first connector 11 and the second connector 12 are adjusted, the limiting bolt passes through the limiting hole 121 and the adjustment hole 111 at different positions.

[0042] Preferably, in this embodiment, the adjustment hole 111 is set as an oblong hole, and the first connecting member 11 can move relative to the limiting member 3 to adjust the position between the first connecting member 11 and the second connecting member 12. At the same time, the limiting member 3 does not need to be released from its limiting position, and the position between the first connecting member 11 and the second connecting member 12 can be adjusted. In this way, the turning machine and the tractor can adjust their positions relative to each other while in operation.

[0043] The vibration damping component 2 of this embodiment can reduce the mechanical vibration between the turning machine and the tractor. Specifically, the vibration damping component 2 includes two clamping parts 21, at least one fastener 22, and an elastic element 23. The clamping portions 211 of the two clamping parts 21 are arranged facing each other to form a clamping channel. The second connecting member 12 passes through the clamping channel. The fastener performs a fastening action on the two clamping parts 21. In this embodiment, the fastener 22 is a bolt and there are two of them. The elastic element 23 is a spring. The spring is sleeved on the bolt. The spring adapts to the change of tension between the first connecting member 11 and the second connecting member 12 through its own elastic change, thereby absorbing and dissipating the mechanical vibration transmitted from the turning machine or the tractor to the first connecting member 11 and the second connecting member 12, so that the turning machine or the tractor can perform a certain swaying or moving action.

[0044] Of course, the vibration damping component 2 in this embodiment can also be provided on the first connection. In addition, the vibration damping component 2 can also be provided on both the first connector 11 and the second connection.

[0045] Furthermore, in this embodiment, a bearing base plate 122 is provided on the second connector 12. The bearing base plate 122 and the clamping member 21 are correspondingly provided. In this embodiment, the bearing base plate 122 extends from the second connector 12. A vibration damping member 4 is provided between the bearing base plate 122 and the clamping member 21. The fastener 22 passes through the bearing base plate 122, the vibration damping member 4 and the clamping member 21 in sequence to lock the bearing base plate 122, the vibration damping member 4 and the clamping member 21 together, thereby preventing the clamping member 21 from sliding relative to the second connector 12. The presence of the bearing base plate 122 provides a reference for the clamping member 21 during assembly, thereby ensuring assembly accuracy. In this embodiment, the vibration damping member 4 is set as a disc-shaped pad. The disc-shaped pad can also absorb the mechanical vibration transmitted to the first connector 11 and the second connector 12 by the turning machine or tractor, thereby sharing the vibration force on the elastic member 23 and helping to extend the life of the elastic member 23.

[0046] Preferably, in this embodiment, the clamping part 211 is adapted to the outer wall of the second connector 12. The clamping part 21 is made of nitrile rubber. By making full use of the high wear resistance, good heat resistance and strong adhesion of nitrile rubber, the clamping part 21 and the second connector 12 are better connected.

[0047] This embodiment also provides a drying machine that uses the above-mentioned connecting device, thereby realizing the adjustment of the position between the drying machine and the tractor, and the mechanical vibration between the drying machine and the tractor is absorbed by the connecting device, thereby avoiding the breakage of the support rod due to mechanical vibration in the prior art and causing damage to the drying machine.

[0048] The drying machine in this embodiment also includes a connecting frame 5 and a lifting arm 6. The lifting arm 6 is connected to the connecting frame 5 via a plug-in module 7, so that the lifting arm 6 can serve as the main connecting structure of the drying machine and be used for connection and fixation with various functional components. Specifically, one end of the lifting arm 6 is connected to the connecting frame 5 via the plug-in module 7, and one side of the connecting frame 5 is connected to the tractor via a plug-in member. The plug-in member can be set as a pin. In this embodiment, the plug-in module 7 includes a limiting insert 71 and a pulling member 73. The limiting insert 71 is set as a pin shaft, and the limiting insert 71 passes through... The connecting frame 5 and the lifting arm 6 are connected by socket holes. A limiting groove 711 is formed on the limiting plug 71. The end of the lifting arm 6 extends into the limiting groove 711 to limit the limiting plug 71 and prevent the limiting plug 71 from moving axially. In addition, a connecting plate 72 is provided on the limiting plug 71. The connecting plate 72 is connected to the pulling member 73. The pulling member 73 is connected to the oil cylinder dustproof locking cover of the turning machine by a rope to pull up the oil cylinder dustproof locking cover when the two wing fingers of the turning machine are not in operation.

[0049] Preferably, the end of the limiting plug 71 in this embodiment is formed with a lubricating oil channel 712.

[0050] Furthermore, in this embodiment, the lifting arm 6 is connected to a plurality of support members 61. The ends of the support members 61 are hinged to the lifting arm 6. When the turning machine is not in operation, the support members 61 are lowered from the connecting arm to provide balanced support for the turning machine. The lifting arm 6 is provided with support locking holes corresponding to the support members 61 on both sides. When the turning machine is in operation, the support members are retracted to detach from the ground and then locked with elastic pins to prevent the support members 61 from contacting the ground again and affecting the operation.

[0051] In this embodiment, the connecting frame 5 is detachably connected to the tractor on the side opposite to the lifting arm 6. Specifically, in this embodiment, the connecting frame 5 is configured as a tripod, with fixing pins 53 at the three corners of the tripod. The fixing pins 53 have socket holes, and the pins are inserted into the socket holes and the clearance holes on the tractor to make the tripod and the tractor movably connected. A connecting ball seat 51 is provided on the crossbeam of the tripod, and the inner ball of the connecting ball seat 51 is connected to the pin shaft on the tripod for the tractor. In this way, when the connection angle between the tractor and the tripod changes, the pin shaft can rotate relative to the connecting ball seat 51 to adapt to the angle change.

[0052] Preferably, in this embodiment, the connecting frame 5 is further provided with tube frames 52 on both sides, and slots 521 are formed on the tube frames 52. One end of the protective member 8 extends into the slot 521. The protective member 8 surrounds the main body of the turning and drying machine and affixes a warning label to remind non-operators not to approach the turning and drying machine.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
