Description

Technical Field

[0001] The utility model relates to the field of green fodder harvester parts, in particular to a clutch disc heat dissipation device for a silage harvester. Background Art

[0002] At present, with the continuous development of animal husbandry, especially dairy farming, the feed made by crushing corn stalks and corn ears is called silage. Silage is gradually becoming the first choice of farmers. After eating silage, dairy cows can achieve the remarkable goals of high milk yield, good milk quality and high nutritional value of milk. Therefore, silage harvesters have become a more common harvesting type in the current agricultural machinery market.

[0003] At present, the large and small clutch plates of the silage harvester's header are connected by the clutch opening flange and the spline pressure plate through the friction plate when working. Since the clutch opening flange is not directly connected to the main shaft but moves synchronously with the friction plate, slippage will occur when the clutch is overloaded. The relative movement between the clutch opening flange and the friction plate will generate a lot of heat, which will damage the friction plate and affect normal work.

[0004] Therefore, a clutch plate heat dissipation device for a silage machine is proposed, which can improve the heat dissipation capacity of the clutch and protect the friction plate. Utility Model Content

[0005] The purpose of the utility model is to provide a clutch plate heat dissipation device for a silage machine to solve the problem that the relative movement between the clutch opening flange and the friction plate generates a large amount of heat, which damages the friction plate and affects normal operation.

[0016] In order to enable those skilled in the art to better understand the technical solution of the utility model, the technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0017] like Figure 1 and Figure 2 As shown, a clutch plate heat dissipation device for a silage machine includes a heat dissipation water tank 1, a valve assembly, a cam mechanism and a needle setting device. The valve assembly includes a water tank valve 2 and a floating rod 3. The water tank valve 2 is located behind the large and small clutch plates. The water tank valve 2 is in an "I" shape. A mounting hole is provided on the lower bottom surface of the heat dissipation water tank 1. The water tank valve 2 includes an upper part, a middle part and a lower part. The middle part of the water tank valve 2 passes through the mounting hole and is located inside the heat dissipation water tank 1. The lower part of the water tank valve 2 is fitted and installed on the lower bottom surface of the heat dissipation water tank 1. The upper part of the water tank valve 2 is located above the middle part of the water tank valve 2 and is located inside the heat dissipation water tank 1. A through hole is provided in the middle part of the water tank valve 2. The floating rod is in a "T" shape and includes a through-connection part and a sealing part 31. The diameter of the sealing part 31 is larger than the diameter of the through-connection part. The cam mechanism It includes a large cam 4 and a small cam 5, and the needle setting device includes a needle setting 6 and a needle setting shaft 7. A transmission rod 8 is connected between the large cam 4 and the small cam 5. The central axes of the large cam 4, the small cam 5 and the transmission rod 8 are located on the same horizontal axis. One end of the needle setting shaft 7 is connected to the small cam 5, and the other end is connected to the needle setting 6. A cam groove is provided on the end of the needle setting shaft 7 connected to the small cam 5. The size of the cam groove matches the size of the protruding portion of the small cam 5. The protruding portion of the small cam 5 is clamped in the cam groove. The connecting portion of the floating rod 3 passes through the connecting hole and the lower end is located above the protruding portion of the large cam 4 and contacts with its plane. It also includes a return spring 9. The hooks at both ends of the return spring 9 are hung on the needle setting 6 at one end and on the main body of the large and small clutch disks at the other end.

[0018] When in use, the clutch opening flange and the friction plate move synchronously. When the clutch is overloaded, the friction plate overheats and slips, and its position shifts, thereby driving the dial pin 6 to rotate. The rotation of the dial pin 6 drives the dial pin shaft 7 to rotate, and the dial pin shaft 7 drives the small cam 5 to rotate. The rotation of the small cam 5 drives the large cam 4 to rotate through the transmission rod 8. During rotation, when the protrusion of the large cam 4 hits the lower end surface of the penetration portion of the floating rod 3, the floating rod 3 moves upward, and a sealing relationship is no longer formed between the sealing portion 31 and the penetration hole, which is equivalent to the valve port of the water tank valve 2 being opened, and the water in the heat dissipation water tank 1 flows down the penetration hole to cool the friction plate. After the clutch opening flange resumes normal operation, the dial pin 6 is pushed back to its original position by the return spring 9, thereby driving the large cam 4 to return, the floating rod 3 to return, and the sealing portion 31 continues to seal the penetration hole.
