Abstract
Description
Technical Field
[0001] The utility model relates to the field of agricultural machinery and equipment, in particular to a mud agitator roller shaft joint for connecting a gearbox of a rotary seeding machine. Background Art
[0002] The mud blade roller joint for connecting the rotary seeding machine gearbox is a mechanical component used to connect the rotary seeding machine gearbox output shaft and the mud blade roller. This joint allows a movable connection between the two so that torque can be transmitted when the rotary seeding machine is working to drive the mud blade roller to rotate. Specifically, this joint usually includes a blade shaft adapter, which is connected to the power output shaft of the side gearbox, and the other end of the blade shaft adapter is fixedly connected to the blade shaft. This design can effectively avoid equipment failures caused by bearing damage, and is also convenient for maintenance and replacement. During use, if the joint is found to be severely worn or damaged, it should be replaced in time to ensure the normal working efficiency and service life of the rotary seeding machine.
[0003] However, the existing mud-mixing knife roller joint often encounters the following problems during use:
[0004] (1) When the mud blade is in use, the soil and weeds turned up by the blade will mix into the connection between the mud blade roller joint and the gearbox, causing the roller to get stuck and affecting normal use.
[0005] (2) The general mud agitator roller joint is directly inserted through the connecting rod of the gearbox. This connection method is too simple and unstable. If it encounters shaking, it is easy to cause the connection part to become unstable or even fall off. Utility Model Content

DETAILED DESCRIPTION
[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] like Figure 1-3As shown, a mud blade roller shaft joint for connecting a rotary seeding machine gearbox includes: a blade shaft joint 1, an interface 2, a first edge 3, a second edge 4, a clamping member 5, two transmission rods 6, a spring 7, an adjusting plate 8, a screw 9, and a nut 10. The interface 2 is provided on the blade shaft joint 1, the first edge 3 is arranged around the interface 2, the second edge 4 is arranged around the first edge 3, the second edge 4 is larger than the first edge 3, the first edge 3 and the second edge 4 are both annular edges, and the first edge 3 and the second edge 4 are arranged concentrically. By arranging two layers of annular edges around the interface 2, a protective barrier is formed to prevent soil and weeds from entering the connection part, thereby reducing the impact on the connection stability and extending the service life of the joint. Two clamping members 5 are provided, and the two clamping members 5 are correspondingly arranged in the extension direction of the interface 2. The clamping member 5 is used to fix the connecting rod of the gearbox during the connection process. By adjusting the position of the clamping member 5, the joint can be quickly installed and disassembled, while ensuring the firmness of the connection.
[0041] In this embodiment, Figure 2-3 As shown, in order to make the roller joint and the connecting rod of the gearbox connected stably, two transmission rods 6 are inserted through the first edge 3 and the second edge 4, and the plug-in ends of the two transmission rods 6 are fixedly connected with two clamps 5 respectively. The transmission rod is a key component connecting the clamp 5 and the edge, responsible for transmitting force, so that the clamp 5 can tightly fix the connecting rod of the gearbox. The spring 7 is sleeved on the rod body of the two transmission rods 6, one end of the spring 7 is connected to the clamp 5, and the other end of the spring 7 is connected to the inner wall of the first edge 3. The spring 7 provides the necessary elastic force, so that the joint can have a certain buffering effect when connected and disconnected, reducing the impact of shock and vibration on the connection stability. Two adjustment plates 8 are provided, and the bottom ends of the two adjustment plates 8 are sleeved on the unplugged ends of the two transmission rods 6, and the bottom of the adjustment plate 8 is arc-shaped. The screw 9 is inserted through the top of the two adjustment plates 8, and the nut 10 is sleeved on the screw 9. At least two nuts 10 are distributed on both sides of each adjustment plate 8. The adjusting piece 8 can generate a lever effect when tightening the nut 10 due to its arc-shaped bottom design, so that the transmission rod can be pried out or pushed in, thereby realizing rapid adjustment of the joint.
[0042] In the above embodiment, Figure 2 As shown, the tool magazine 11 is arranged on the shaft body of the knife shaft joint 1. The plug interface 12 is longitudinally opened on the tool magazine 11, and the fixed connection hole 13 is transversely opened on one side of the tool magazine 11. The tool magazine 11 is used to install and store the mud knives. The plug interface 12 and the fixed connection hole 13 provide a connection method between the tool magazine 11 and the knife shaft joint 1 to ensure the stable installation of the tool magazine 11. The knife shaft connection plate 14 is fixedly arranged on one side of the knife shaft joint 1. The knife shaft connection plate 14 is fixedly arranged on one side of the knife shaft joint 1, which may be used to connect the output shaft of the gearbox to transmit power to the mud knife roller.
[0043] It should be noted that the utility model is designed to connect the rotary seeding machine gearbox with a mud blade roller joint. When in use, insert the blade into the plug interface 12. When connection is required, tighten the nut 10 inward. The top ends of the two adjustment pieces 8 are squeezed inward by the nut 10 and slide on the screw 9. The bottom ends of the two adjustment pieces 8 will pry out the two transmission rods 6 outward, and then pull the two clamps 5 to squeeze the spring 7, adding a gap for the connection of the interface 2. After the connecting rod of the gearbox is inserted into the interface 2, loosen the nut 10 outward, the two adjustment pieces 8 lose force, and the spring 7 begins to rebound. The rebound pushes the clamp 5 to squeeze the connecting rod of the gearbox. The squeezed clamp 5 will firmly fix the connecting rod. If it is shaken, the spring 7 will also start to buffer and prevent the connection from falling off. At this point, the use process ends.
[0044] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
