Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a connecting seat structure and a harvester frame. Background Art

[0002] In a combine harvester, the cross-bridge connecting seat assemblies are used in pairs and fixed at the middle positions of the front sections of the left and right side walls of the harvester frame to support and limit both ends of the cross-bridge transmission shaft, and the cross-bridge can rotate around the axis concentric with the two groups of cross-bridge connecting seats.

[0003] The existing cross-bridge connecting seat is a casting and is connected and fixed to the machine body through fixing bolts. A stop block is fixed to the front section of the cross-bridge connecting seat through a pin shaft to form a circular limiting ring for limiting the cross-bridge transmission shaft. However, in this way, the stop block and the transmission shaft always maintain hard friction, which is easy to cause wear, and the load-bearing mainly concentrates on the pin shaft position, which is extremely easy to cause bending deformation or even fracture of the pin shaft, affecting the stability and service life of the overall structure.

[0004] Therefore, there is an urgent need to provide a connecting seat structure and a harvester frame to solve the problems existing in the prior art to a certain extent. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a connecting seat structure and a harvester frame to optimize the connecting seat structure to a certain extent, reduce the hard friction between the connecting seat and the shaft, and improve the service life of the connecting seat.

[0006] A connecting seat structure provided by the utility model includes a positioning seat, an outer stop block and an inner stop block; a first limiting space is formed by surrounding the outer stop block and the positioning seat, the inner stop block is made of plastic material, the inner stop block is located in the first limiting space, and the first limiting space is reduced to a second limiting space for limiting the transmission shaft.

[0007] Wherein, the connecting seat structure provided by the utility model further includes a connecting piece, one end of the outer stop block is rotatably connected to the positioning seat, and the other end is connected to the positioning seat through the connecting piece.

[0008] Specifically, the connecting piece is a bolt, a through hole is formed at one end of the outer stop block, a corresponding hole is formed at the position of the positioning seat corresponding to the through hole, and the corresponding hole is a threaded hole, so that one end of the outer stop block is detachably connected to the positioning seat.

[0009] Furthermore, the connecting seat structure provided by the utility model further includes a rotating piece, the rotating piece passes through the positioning seat and the end of the outer stop block far from the connecting piece, and the rotating piece is welded to the positioning seat, and the rotating piece is rotatably connected to the outer stop block, so that the outer stop block can be rotatably connected to the positioning seat.

[0010] Among them, the positioning seat is U-shaped, and the outer stopper is horizontally mounted on the opening of the U-shaped positioning seat to form the first limiting space.

[0011] Specifically, the inner stopper is arc-shaped, and the inner arc of the inner stopper and the positioning seat form the circular second limiting space.

[0012] Furthermore, the outer stopper is made of a high-hardness metal material.

[0013] Even further, the metal material is 42CrMo, 45 steel, 40Cr, 30CrMo or 35CrMo.

[0014] Even further, the plastic material is nylon, PEEK, POM, polyester fiber or bakelite.

[0015] Compared with the prior art, the connecting seat structure provided by the present utility model has the following advantages:

[0016] The connecting seat structure provided by the present utility model includes a positioning seat, an outer stopper and an inner stopper; the outer stopper and the positioning seat enclose to form a first limiting space, the inner stopper is made of a plastic material, the inner stopper is located in the first limiting space, and the first limiting space is reduced to a second limiting space for limiting a transmission shaft.

[0017] From this analysis, it can be seen that the first limiting space formed by the outer stopper and the positioning seat can provide an installation basis for the inner stopper. And in this application, by making the outer stopper and the inner stopper be of a split structure, it changes the situation that the positioning pin shaft generated by a single stopper structure at the present stage is prone to bending deformation. That is, by contacting the inner stopper with the transmission shaft, it can play a certain buffering role. And when the inner stopper is severely worn, only the inner stopper needs to be replaced, which improves the service life of the overall structure.

[0018] Moreover, since the inner stopper in this application is made of a plastic material, and the plastic material has a smaller friction force than metal and has a certain self-lubricating effect. Therefore, it can reduce the friction with the transmission shaft, and the plastic material is relatively soft in texture, which can further increase the buffering of the transmission shaft during vibration and improve the stability of the overall equipment operation.

[0019] In addition, the present utility model also provides a harvester frame, including the above-mentioned connecting seat structure, and the connecting seat structure is welded to the harvester frame.

[0020] For the harvester frame adopting the connecting seat structure provided by the present application, the positioning transmission shaft is more stable, and the rotation of the transmission shaft is smoother. When wear occurs, the replacement of the inner retaining block can be used instead of the replacement of the overall connecting seat structure. Therefore, the connection between the connecting seat structure and the harvester frame can be achieved by welding, making the overall structure more stable and firm and improving the service life of the structure.

[0034] As Figure 1 shown, the present utility model provides a connecting seat structure, including a positioning seat 1, an outer stopper 2 and an inner stopper 3; a first limiting space is formed by enclosing the outer stopper 2 and the positioning seat 1, the inner stopper 3 is made of a plastic material, the inner stopper 3 is located in the first limiting space, and the first limiting space is reduced to a second limiting space for limiting a transmission shaft.

[0035] Compared with the prior art, the connecting seat structure provided by the present utility model has the following advantages:

[0036] For the connecting seat structure provided by the present utility model, through the first limiting space formed by the outer stopper 2 and the positioning seat 1, an installation basis can be provided for the inner stopper 3. And in this application, by making the outer stopper 2 and the inner stopper 3 be of a split structure, it changes the situation in the current stage that the positioning pin shaft generated by a single stopper structure is prone to bending deformation. That is, by contacting the inner stopper 3 with the transmission shaft, a certain degree of buffering effect can be achieved. And when the inner stopper 3 is severely worn, only the inner stopper 3 needs to be replaced, improving the service life of the overall structure.

[0037] Moreover, since the inner stopper 3 in this application is made of a plastic material, and the plastic material has less friction compared with metal and has a certain self-lubricating effect. Therefore, it can reduce the friction with the transmission shaft, and the plastic material is relatively soft in texture, which can further increase the buffering of the transmission shaft during vibration and improve the stability of the operation of the overall equipment.

[0038] Preferably, the outer stopper 2 in this application is made of a high-hardness metal material, and further preferably, the metal material is 42CrMo, 45 steel, 40Cr, 30CrMo or 35CrMo.

[0039] Preferably, the plastic material in this application is nylon, PEEK, POM, polyester fiber or bakelite.

[0040] Optionally, as shown in Figure 1 shown, the connecting seat structure provided by the present utility model further includes a connecting member 201. One end of the outer stopper 2 is rotatably connected to the positioning seat 1, and the other end is connected to the positioning seat 1 through the connecting member 201.

[0041] In this application, the connecting member 201 is a bolt. A through hole is formed at one end of the outer stopper 2, and a positioning hole 101 corresponding to the through hole is formed in the positioning seat 1, and the positioning hole 101 is a threaded hole, so that one end of the outer stopper 2 is detachably connected to the positioning seat 1.

[0042] Preferably, in this application, the positioning hole 101 includes a threaded hole portion and a positioning portion. The diameter of the positioning portion is larger than that of the threaded hole portion. Since the installation position space of the connecting seat structure is small, therefore, through the formed positioning portion with a larger diameter, when the connecting member 201 needs to be installed, the end of the connecting member 201 can pass through the through hole and first enter a part of the positioning portion, so that the bolt can finally enter the threaded hole portion to realize the limit of the end of the outer stopper 2.

[0043] Optionally, as shown in Figure 1 shown, the connecting seat structure provided by the present utility model further includes a rotating member 102. The rotating member 102 passes through the positioning seat 1 and the end of the outer stopper 2 away from the connecting member 201, and the rotating member 102 is welded to the positioning seat 1, and the rotating member 102 is rotatably connected to the outer stopper 2, so that the outer stopper 2 can be rotatably connected to the positioning seat 1.

[0044] Optionally, as shown in Figure 1 Combined with Figure 2 shown, the positioning seat 1 in this application is U-shaped, and the outer stopper 2 is horizontally arranged on the opening of the U-shaped positioning seat 1 to form a first limiting space.

[0045] Through the U-shaped positioning seat 1, on the one hand, it can provide a basis for the installation of the outer stopper 2, so that one end of the outer stopper 2 can be rotatably connected to the positioning seat 1, and the other end is detachably connected to the positioning seat 1. On the other hand, through the U-shaped positioning seat 1, it can have an arc-shaped curved surface, so as to cooperate with the inner stopper 3 to form a circular second limiting space for positioning the transmission shaft.

[0046] Therefore, the inner stopper 3 in this application is arc-shaped, and the inner arc of the inner stopper can be semi-circular or an arc less than a semi-circle, so as to realize the above-mentioned formation of the circular second limiting space.

[0047] In addition, the present utility model also provides a harvester frame, including the above-mentioned connecting seat structure, and the connecting seat structure is welded to the harvester frame.

[0048] For the harvester frame adopting the connecting seat structure provided by the present application, the positioning transmission shaft is more stable, and the rotation of the transmission shaft is smoother. When wear occurs, the replacement of the inner block 3 can be used instead of the replacement of the overall connecting seat structure. Therefore, the connection between the connecting seat structure and the harvester frame can be realized by welding, making the overall structure more stable and firm and improving the service life of the structure.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
