[0024] Specific examples are given below.
[0025] like Figures 1 to 4 As shown, a petroleum drilling vibrating screen according to an embodiment of the utility model comprises a screening body 1; a support rod 2 is fixedly connected to the interior of the screening body 1; a swing frame 3 is placed inside the screening body 1, and the swing frame 3 is placed at the top position of the support rod 2; a filter tank 4 is placed inside the swing frame 3; a sliding slot 5 is fixedly connected to the outer side wall of the swing frame 3; a rotating push rod 6 is rotatably connected to the interior of the screening body 1; the rotating push rod 6 is slidably connected to the inner position of the sliding slot 5; a handle bar 7 is fixedly connected to the interior of the filter tank 4; the interior of the screening body 1 A collecting drawer 8 is placed in the bottom, and the collecting drawer 8 is arranged at a position corresponding to the bottom of the swing frame 3; during operation, when it is necessary to vibrate and screen the mud produced by oil drilling, the mud can be placed in the filter tank 4, and then the driving motor can be used to drive the rotating push rod 6 to rotate, so that the rotating push rod 6 slides up and down in the sliding groove 5, thereby driving the swing frame 3 to vibrate left and right in the screening body 1, so that the mud can be screened. When the mud screening is completed, the handle rod 7 can be pulled to take the filter tank 4 out of the swing frame 3, so that the cleaning of the filter tank 4 can be more convenient.
[0026] like Figure 1As shown, a fixed plug rod 9 is fixedly connected to the top of the screening body 1; a sealing cover plate 10 is placed on the top of the screening body 1, and the sealing cover plate 10 is sleeved on the fixed plug rod 9; a fixed thread block 11 is threadedly connected to the top of the fixed plug rod 9; the fixed thread block 11 is arranged at the position corresponding to the sealing cover plate 10; during operation, when the mud is screened through the swing frame 3 and the filter tank 4, the sealing cover plate 10 can be sleeved on the fixed plug rod 9, and the fixed thread block 11 can be screwed into the inside of the fixed plug rod 9 to fix the sealing cover plate 10, which can effectively avoid the situation where the mud is thrown out of the filter tank 4 when the mud is screened, so that the screening effect of the mud is better.
[0027] like Figures 2 to 4 As shown, a limit rod 12 is fixedly connected to the interior of the screening body 1; a limit groove 13 is provided on the side wall of the swing frame 3; the limit rod 12 is slidably connected to the internal position of the limit groove 13; during operation, when the swing frame 3 slides inside the screening body 1, the limit groove 13 is limited by the limit rod 12, so that the screening body 1 is less likely to tilt when sliding, and the sliding of the screening body 1 is more stable.
[0028] like Figure 2 and Figure 4 As shown, the internal rotation of the swing frame 3 is connected with an anti-wear pulley 14; a pulley groove 15 is opened on the top of the support rod 2; the anti-wear pulley 14 is arranged at the internal position of the pulley groove 15; during operation, when the swing frame 3 slides inside the screening body 1, by arranging the anti-wear pulley 14 inside the swing frame 3 and making the anti-wear pulley 14 rotate inside the pulley groove 15, the sliding friction between the swing frame 3 and the support rod 2 can be converted into rolling friction, so that the friction between the support rod 2 and the swing frame 3 is smaller.
[0029] like Figure 5 As shown, a plurality of classification slots 16 are provided inside the collecting drawer 8, and the classification slots 16 are arranged at an angle inside the collecting drawer 8; during operation, when mud and a small volume of sand and gravel fall into the collecting drawer 8, by arranging the classification slots 16 inside the collecting drawer 8, the sand and gravel can stay in the internal position of the classification slots 16, so that the screening effect of the mud and sand and gravel is better.
[0030] like Figure 6As shown, the interior of the rotating push rod 6 is rotatably connected with a positioning block 17; the positioning block 17 is rotatably connected at an internal position of the screening body 1; a plurality of balls 18 are provided between the screening body 1 and the positioning block 17, and the side walls of the balls 18 are in contact with the side walls of the screening body 1 and the positioning block 17; during operation, when the rotating push rod 6 rotates inside the screening body 1, the rotation of the positioning block 17 is restricted by the screening body 1, so that the rotation of the rotating push rod 6 can be more stable, and at the same time, the balls 18 are provided between the screening body 1 and the positioning block 17, so that the friction between the screening body 1 and the positioning block 17 can be smaller, thereby reducing the wear between the screening body 1 and the positioning block 17.
[0031] During operation, when it is necessary to vibrate and screen the mud produced by oil drilling, the mud can be placed in the filter tank 4, and then the driving motor can be used to drive the rotating push rod 6 to rotate, so that the rotating push rod 6 slides up and down in the sliding tank 5, thereby driving the swing frame 3 to vibrate left and right in the screening body 1, so that the mud can be screened. After the mud screening is completed, the handle bar 7 can be pulled to take the filter tank 4 out of the swing frame 3, so that the cleaning of the filter tank 4 can be more convenient.
[0032] When the mud is screened by the swing frame 3 and the filter tank 4, the sealing cover plate 10 can be sleeved on the fixed plug rod 9, and the fixed threaded block 11 can be screwed into the interior of the fixed plug rod 9 to fix the sealing cover plate 10. This can effectively prevent the mud from being thrown out of the filter tank 4 when the mud is screened, thereby achieving a better screening effect for the mud.
[0033] When the swing frame 3 slides inside the screening body 1, the limiting groove 13 is limited by the limiting rod 12, so that the screening body 1 is less likely to tilt when sliding, making the sliding of the screening body 1 more stable.
[0034] When the swing frame 3 slides inside the screening body 1, by arranging an anti-wear pulley 14 inside the swing frame 3 and making the anti-wear pulley 14 rotate inside the pulley groove 15, the sliding friction between the swing frame 3 and the support rod 2 can be converted into rolling friction, so that the friction force between the support rod 2 and the swing frame 3 is smaller.
[0035] When the mud and a small volume of sand and gravel fall into the collecting drawer 8, by setting a classification trough 16 inside the collecting drawer 8, the sand and gravel can stay in the internal position of the classification trough 16, so that the screening effect of the mud and sand and gravel is better.
[0036] When the rotating push rod 6 rotates inside the screening body 1, the rotation of the positioning block 17 is restricted by the screening body 1, so that the rotation of the rotating push rod 6 can be more stable. At the same time, a ball 18 is arranged between the screening body 1 and the positioning block 17, which can reduce the friction between the screening body 1 and the positioning block 17, thereby reducing the wear between the screening body 1 and the positioning block 17.
[0037] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
