Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of salt production equipment, in particular to an M-type universal joint device. Background Art
[0002] Floating suction salt collection is a commonly used salt collection method in salt production. It requires the use of a specific floating suction salt collection device, which includes a power unit, a salt collecting device, and a salt transporting device. The power unit usually adopts a crawler salt collector power unit. The salt collecting device is composed of a hydraulic lifting device and a salt collecting hopper, and the salt transporting device is composed of a connecting elbow, a mud pump, a universal pipe, and a plastic hose. The characteristic of this method is that the discharge port of the salt collecting hopper is connected to the suction port of the mud pump through a connecting elbow, and the mud pump outlet is connected to the brine transporting plastic hose. The brine transporting plastic hose is partially supported by a floating net in the brine pool and floats on the brine surface. In this way, the salt and brine mixture is sent to the collection point in the plastic hose for separation and then stored in the granary, thereby completing the salt collection process. This salt collection method has a simple structure, is safe and convenient to use and maintain, has low maintenance cost, and has a fast mechanical moving speed. It can immediately pull up the tarpaulin to shelter from rain on rainy days, thereby enhancing the rainproof ability of the salt pool and increasing the amount of salt stored in the granary.
[0003] During the use of the traction machine in the current floating suction salt collection device, the motor pump body outlet on the traction machine needs to be connected to the pipeline, and the pipeline needs to be pulled in the brine to perform various curved movements. However, the existing hose is easily damaged by repeated bending during use, and it also affects the flow of salt and brine inside the pipeline. Therefore, it is not suitable. To this end, we propose an M-type universal joint device. Utility Model Content
[0004] The purpose of the utility model is to provide an M-type universal joint device, which has the advantage of being able to enable the interface of the motor pump body on the traction machine and the traction pipeline to be rotatably connected, thereby efficiently transporting salt and brine. It solves the problem that during the use of the traction machine in the current floating suction salt collection device, the outlet of the motor pump body on the traction machine needs to be connected to the pipeline, and the pipeline needs to be pulled in the brine to perform various curved movements. The existing hose is easily damaged due to repeated bending during use, and also affects the flow of salt and brine inside the pipeline, making it unsuitable.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an M-type universal joint device, comprising an interface elbow and an M-type tube, both ends of the M-type tube are fixedly connected to connecting sleeves, the ends of the two connecting sleeves are fixedly connected to fixed flanges, one end of the two interface elbows is fixedly sleeved with sealed bearings, the outer surfaces of the two sealed bearings are fixedly sleeved with connecting flanges, the connecting flanges and the fixed flanges are fixedly connected by bolts, and one end of the two sealed bearings is respectively located inside the two connecting sleeves.
[0006] Preferably, an annular sealing groove is provided on the top of the inner wall of the two connecting sleeves, a sealing ring is provided inside the two annular sealing grooves, and an annular protrusion is provided at one end of the two interface bends close to the sealing bearing, and the annular protrusion is located inside the annular sealing groove.

[0008] Preferably, the outer surfaces of the two interface elbows are fixedly sleeved with connecting bearings, and the outer surfaces of the two connecting bearings are fixedly connected by a connecting rod.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] 1. The utility model achieves the effect of enabling the interface of the motor pump body on the tractor and the traction pipeline to be rotatably connected and efficiently transporting salt and brine by arranging an M-shaped tube, an interface elbow, a sealed bearing, a fixed flange and a connecting flange. The ends of the two interface elbows are fixedly connected to the outlet of the motor pump on the tractor and the salt delivery pipeline respectively. When the tractor moves, the salt delivery pipeline can rotate respectively with the sealed bearing as the axis to adapt to various curved movements of the salt delivery pipeline due to traction in the brine, thereby ensuring efficient transportation of salt and brine, avoiding bending of the pipeline and extending the service life.
[0011] 2. The utility model improves the sealing effect between the connecting sleeve and the interface elbow by providing an annular sealing groove, a sealing ring and an annular protrusion. The annular protrusion on the interface elbow is inserted into the annular sealing groove and squeezes the sealing ring. The deformed sealing ring seals the connecting sleeve and the interface elbow to prevent brine leakage.
[0012] 3. The utility model achieves the effect of preventing the two interface elbows from deforming due to the pulling process by providing a connecting bearing and a connecting rod. The two interface elbows are movably connected by the two connecting bearings and the connecting rod to withstand the pulling force exerted on the two interface elbows, thereby avoiding deformation of the M-shaped tube.
