[0002] Agricultural machinery refers to various machines used in the crop planting and animal husbandry production processes, as well as in the primary processing and handling of agricultural and livestock products. Swing-arm agricultural machinery, such as lawn mowers and rotary tillers, have adjustable frame angles to obtain different working areas or facilitate transportation and transshipment. The transmission method of existing swing-arm agricultural machinery mostly uses a single shaft drive, that is, a drive shaft is used to connect the power machinery and the power output end of the agricultural machinery, and the two ends of the drive shaft are connected by a universal joint.

[0003] In the prior art, when the machine is running, dirt easily falls into the internal joint of the universal joint, causing the internal friction of the universal joint to increase, which will accelerate the wear of the universal joint and reduce the service life of the universal joint. Therefore, it is necessary to propose a wear-resistant agricultural machinery transmission component to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a wear-resistant agricultural machinery transmission component to solve the problem that when the machinery is running, mud easily falls inside the universal joint, causing the internal friction of the universal joint to increase, which will accelerate the wear of the universal joint and reduce the service life of the universal joint.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant agricultural machinery transmission assembly, comprising a power output shaft, a mechanical operating shaft and a lower protective shell, the upper surface of the lower protective shell is hinged with an upper protective shell, and the lower protective shell and the upper protective shell are arranged relative to each other, and the ends of the power output shaft and the mechanical operating shaft close to each other are connected with the same cross universal joint, and both ends of the inner wall of the lower protective shell are fixedly installed with a first airbag, and both ends of the inner wall of the upper protective shell are fixedly installed with a second airbag, the top of the first airbag is in active contact with the bottom of the second airbag, the top of the first airbag is fixedly installed with a first arc sleeve, and the bottom of the second airbag is fixedly installed with a second arc sleeve, the first arc sleeve and the second arc sleeve are arranged in cooperation, and the power output shaft and the mechanical operating shaft are respectively located between the relative first arc sleeve and the second arc sleeve.

[0009] Preferably, a fixing plate is fixedly installed on one side of the lower protective shell and the upper protective shell away from the hinge, a fixing hole is provided on the fixing plate, a fixing bolt is provided inside the fixing hole, and a nut is threadedly connected to the fixing bolt.

[0010] Technical effects and advantages of this utility model:

[0011] 1. When working, the lower and upper protective shells are opened and stuck on the outside of the cross universal joint. The first airbag, the second airbag, the lower and upper protective shells form a closed space and protect the cross universal joint inside the closed space, which can prevent mud from falling inside the cross universal joint and increasing friction.

[0012] 2. During operation, the power output shaft and the mechanical operating shaft will squeeze the first airbag and the second airbag. One of the second airbags will squeeze the lubricating oil bag inside it. The lubricating oil inside the lubricating oil bag will drip into the interior of the cross joint through the oil outlet pipe to lubricate the cross joint, which can reduce the friction inside the cross joint, reduce the wear of the cross joint, and increase the service life of the cross joint.

[0013] 3. During operation, if the ground fluctuates greatly, the lubricating oil bag will be squeezed more, causing more lubricating oil to drip. The excess lubricating oil will drip into the inside of the recovery tray and flow into the recovery bag along the return oil pipe. After treatment, it can be reused, which can save resources.

[0014] 4. During operation, the first airbag and the second airbag can discharge the heat generated by the friction of the cross joint by pumping and releasing air, which can avoid high temperature from accelerating the wear of the cross joint, better protect the cross joint, and increase the service life of the cross joint.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In agricultural farming, due to the uneven ground, farming machinery needs to be adjusted to different heights to adapt to different land farming, and the power to drive the machinery is generally set to one. If multiple power sources are set, it will take up a large space and increase the production cost of the machinery. In order to ensure that one power source can drive the machinery to be adjusted to different heights for farming, it is necessary to ensure that the machinery can be connected to the power source at different heights and that the power source can drive the machinery to operate. The setting of the universal joint can just meet the above situation, so the universal joint is an indispensable transmission part.

[0021] The utility model provides Figure 1 - Figure 3 The wear-resistant agricultural machinery transmission assembly shown includes a power output shaft 7, a mechanical operating shaft 8 and a lower protective shell 1. The ends of the power output shaft 7 and the mechanical operating shaft 8 that are close to each other are connected to the same cross universal joint 9. The power output shaft 7 and the mechanical operating shaft 8 are connected by the cross universal joint 9, which can not only meet the purpose of adjusting the machinery, but also ensure that the power output shaft 7 can drive the mechanical operating shaft 8 to operate, thereby ensuring normal farming of the machinery. This type of setting is a conventional setting, so it will not be elaborated on.

[0022] In order to solve the problem that mud easily falls inside the universal joint when the machine is running, causing the internal friction of the universal joint to increase, which will accelerate the wear of the universal joint and reduce the service life of the universal joint, the utility model is hinged with an upper protective shell 2 on the upper surface of the lower protective shell 1, and the lower protective shell 1 and the upper protective shell 2 are arranged relatively to each other, and the first airbags 3 are fixedly installed at both ends of the inner wall of the lower protective shell 1, and the second airbags 4 are fixedly installed at both ends of the inner wall of the upper protective shell 2. The top of the first airbag 3 is in active contact with the bottom of the second airbag 4, and a first arc-shaped sleeve 5 is fixedly installed on the top of the first airbag 3, and a second arc-shaped sleeve 6 is fixedly installed on the bottom of the second airbag 4. The first arc-shaped sleeve 5 and the second arc-shaped sleeve 6 are arranged in coordination, and the power output shaft 7 and the mechanical operation shaft 8 are respectively Located between the relative first arc sleeve 5 and the second arc sleeve 6, when working, the lower protective shell 1 and the upper protective shell 2 are opened and stuck on the outside of the cross universal joint 9. At this time, the first arc sleeve 5 and the second arc sleeve 6 are respectively stuck on the power output shaft 7 and the mechanical operation shaft 8, so that the lower protective shell 1 and the upper protective shell 2 can be fixed on the outside of the cross universal joint 9. The first airbag 3, the second airbag 4, the lower protective shell 1 and the upper protective shell 2 form an enclosed space and protect the cross universal joint 9 inside the enclosed space, which can avoid the problem of mud falling inside the cross universal joint 9 to increase friction. The first airbag 3 and the second airbag 4 can both play a supporting role and not affect the angle change of the cross universal joint 9, ensuring that the machine can be adjusted normally.

[0023] Furthermore, the utility model provides a lubricating oil bag inside one of the second air bags 4, and an oil outlet pipe 10 is fixedly connected to the oil outlet of the lubricating oil bag. The end of the oil outlet pipe 10 away from the lubricating oil bag is located above the cross universal joint 9. During operation, the power output shaft 7 drives the mechanical operating shaft 8 to rotate through the cross universal joint 9. The power output shaft 7 and the mechanical operating shaft 8 will squeeze the first air bags 3 and the second air bags 4. One of the second air bags 4 will squeeze the lubricating oil bag inside it. The lubricating oil inside the lubricating oil bag will drip into the cross universal joint 9 through the oil outlet pipe 10 to lubricate the cross universal joint 9, which can reduce the friction inside the cross universal joint 9, reduce the wear of the cross universal joint 9, and increase the service life of the cross universal joint 9, thereby increasing the service life of the transmission component.

[0024] Furthermore, the utility model provides a recovery bag inside one of the first air bags 3, and a return oil pipe 11 is fixedly connected to the oil inlet of the recovery bag, and a recovery plate 12 is fixedly connected to the end of the return oil pipe 11 away from the recovery bag. The recovery plate 12 is located below the cross universal joint 9. During operation, if the land fluctuates greatly, the lubricating oil bag will be squeezed more, causing more lubricating oil to drip. The excess lubricating oil will drip into the recovery plate 12 and flow along the return oil pipe 11 into the recovery bag. After processing, it can be reused, which can save resources. At the same time, the other first air bag 3 and the second air bag 4 can discharge the heat generated by the friction of the cross universal joint 9 by pumping out air, which can avoid high temperature accelerating the wear of the cross universal joint 9, better protect the cross universal joint 9, and increase the service life of the cross universal joint 9.

[0025] The first airbag 3 and the second airbag 4 are both provided with an air inlet pipe and an air outlet pipe, and the air inlet pipe and the air outlet pipe are both provided with a one-way valve. The setting of the one-way valves on the air inlet pipe and the air outlet pipe ensures that the first airbag 3 and the second airbag 4 can normally draw and release air. This type of setting is a conventional setting, so it will not be elaborated on.

[0026] A fixing plate 13 is fixedly installed on the side of the lower protective shell 1 and the upper protective shell 2 away from the hinge. A fixing hole is provided on the fixing plate 13, and a fixing bolt 14 is provided inside the fixing hole. A nut is threadedly connected to the fixing bolt 14. The setting of the fixing plate 13 and the fixing bolt 14 makes it convenient to fix the lower protective shell 1 and the upper protective shell 2, and facilitates the disassembly and assembly of the equipment.
