Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an enhanced drive shaft for agricultural machinery. By setting a lubrication component, when the friction between the universal joint and the drive shaft increases, the hydraulic lifting rod inside the lubrication component is started to drive the stabilizing rod and the sealing disk to move downward. Because the surface of the sealing disk is adapted to the inner wall of the containing cylinder, the lubricating oil stored in the containing cylinder can be transported to the inside of the connecting pipe during the movement of the sealing disk, and then the lubricating oil is dripped from the bottom end of the connecting pipe to the connection between the universal joint and the drive shaft, thereby reducing the friction between the universal joint and the drive shaft, thereby facilitating the operation of the drive shaft and saving time, so as to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an enhanced transmission shaft for agricultural machinery, comprising a transmission shaft, a dustproof component is arranged on the surface of the transmission shaft, both ends of the transmission shaft are fixedly connected with connectors, one side of the upper surface of the connector is fixedly connected with a lubrication component, and one end of the connector is movably sleeved with a universal joint;

[0009] Wherein, the bottom end of the limiting connecting rod is adapted to the inside of the groove, and the length of the limiting connecting rod is the same as the depth of the groove.

[0010] The interiors of the first dustproof shell and the second dustproof shell are tightly fitted to the surface of the transmission shaft, and the length of the first dustproof shell is greater than the length of the transmission shaft.

[0011] Wherein, the lubrication assembly includes a support plate and a connecting plate, the top end of the side wall of the support plate is fixedly connected to the connecting plate, and the bottom end of the support plate is connected to one side of the upper surface of the connecting head.

[0012] Wherein, a hydraulic lifting rod is detachably mounted on the lower surface of the connecting plate, a stabilizing rod is fixedly connected to the bottom end of the hydraulic lifting rod, and a sealing disk is fixedly connected to the bottom end of the stabilizing rod.

[0013] Among them, a containing cylinder is fixedly connected to the bottom end of the side wall of the support plate, and the bottom end of the containing cylinder is connected to a connecting pipe. The interior of the containing cylinder is filled with lubricating oil. The interior of the containing cylinder is adapted to the surface of the sealing disk, and the bottom end of the connecting pipe is located directly above the connection between the transmission shaft and the universal joint.

[0014] The beneficial effects of the above technical solution of the utility model are as follows:

[0015] 1. In the above scheme, the enhanced transmission shaft is provided with a dustproof component. When dust is about to fall on the surface of the transmission shaft, the dustproof component provided on the surface of the transmission shaft will work. Because the interior of the first dustproof shell and the second dustproof shell are closely fitted with the surface of the transmission shaft, the falling dust can be prevented from entering the interior of the transmission shaft, thereby ensuring the quality of the transmission shaft and reducing losses.

[0016] 2. In the above scheme, the enhanced drive shaft is provided with a lubrication assembly. When the friction between the universal joint and the drive shaft increases, the hydraulic lifting rod inside the lubrication assembly is started to drive the stabilizing rod and the sealing disk to move downward. Because the surface of the sealing disk is adapted to the inner wall of the containing cylinder, the lubricating oil stored in the containing cylinder can be transported to the inside of the connecting pipe during the movement of the sealing disk. Then, the lubricating oil is dripped from the bottom end of the connecting pipe to the connection between the universal joint and the drive shaft, thereby reducing the friction between the universal joint and the drive shaft, thereby facilitating the operation of the drive shaft and saving time.

[0027] Benefits: The provision of the groove 22 and the limiting connecting rod 24 facilitates separation of the first dustproof shell 21 from the second dustproof shell 23, thereby enhancing the practicability of the device.

[0028] The working process of the utility model is as follows:

[0029] When the reinforced transmission shaft is in use, a dustproof component 2 is provided to reduce the cost of use. When dust is about to fall on the surface of the transmission shaft 1, the dustproof component 2 arranged on the surface of the transmission shaft 1 will work.
