[0015] The utility model is described in detail below in conjunction with the accompanying drawings. As shown in Figure 1, a novel lubricating oil additive weighing mechanism includes a bracket 1, a weighing sensor 4 is fixedly installed on the upper side of the interior of the bracket 1, a chassis 5 is fixedly installed on the upper part of the weighing sensor 4, a weighing bucket 6 is fixedly installed on the chassis 5, a liquid outlet valve 7 is installed at the liquid outlet opened at the lower part of one side of the weighing bucket 6, a controller 8 is fixedly installed on one side of the interior of the bracket 1, the controller 8 adopts a single-chip controller, and a liquid outlet pipe assembly 9 is installed on the bracket 1.

[0016] In this embodiment, combined with the Figure 2 As shown, the liquid outlet pipe assembly 9 includes a liquid storage tank 91, a delivery pump 92 and an angle rotating motor 95. The outlet of the liquid storage tank 91 is connected to the inlet pipeline of the delivery pump 92. The outlet of the delivery pump 92 is flange-connected with a connecting pipe 93, and the connecting pipe 93 adopts a bellows. The output shaft of the angle rotating motor 95 is fixedly installed with a sealing pipe 96. The upper end of the sealing pipe 96 is closed, and the lower end of the sealing pipe 96 is threadedly connected with a rotating pipe 94. The end of the connecting pipe 93 away from the delivery pump 92 is flange-connected with a connector opened on one side of the rotating pipe 94. The lower end of the rotating pipe 94 is higher than the weighing bucket 6. The liquid storage tank 91 and the delivery pump 92 and the angle rotating motor 95 are both fixedly mounted on the upper part of the bracket 1. When the piston 3 is separated from the weighing barrel 6, the angle rotating motor 95 drives the rotating tube 94 to rotate, so that the lower end of the rotating tube 94 rotates to the upper part of the weighing barrel 6, and the delivery pump 92 is started to deliver the additive in the liquid storage tank 91 to the weighing barrel 6, and then the rotating tube 94 is rotated back to its original position. The connecting tube 93 allows the rotating tube 94 to have a certain range of movement. When the lubricating oil additive is discharged through the liquid outlet valve 7, the electric telescopic rod 2 drives the piston 3 to move downward, so that the piston 3 pushes down the additive hanging on the inner wall of the weighing barrel 6, thereby reducing the weighing error caused by hanging on the wall.

[0017] In this embodiment, specifically, the liquid storage tank 91 , the delivery pump 92 , the angle rotation motor 95 , the weighing sensor 4 , the electric telescopic rod 2 , and the liquid outlet valve 7 are all electrically connected to the controller 8 .

[0018] In this embodiment, specifically, an electric telescopic rod 2 is fixedly installed on the left upper portion of the bracket 1 , and a piston 3 is installed at the output rod of the electric telescopic rod 2 .

[0019] In this embodiment, specifically, the piston 3 is arranged opposite to the weighing barrel 6 , and the inner diameter of the piston 3 is adapted to the inner diameter of the weighing barrel 6 .

[0020] How it works

[0021] In the utility model, when the lubricating oil additive needs to be weighed, the piston 3 is first separated from the weighing barrel 6, and the lubricating oil additive is added to the weighing barrel 6 using the liquid outlet pipe assembly 9. The weighing sensor 4 weighs the weight of the lubricating oil additive and transmits the signal to the controller 8 to achieve the function of weighing the lubricating oil additive.

[0022] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
