DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0027] The following describes the specific implementation of the utility model in detail with reference to specific embodiments.

[0028] Please refer toFigures 1 to 4 , a quantitative filling device for oilfield drilling cuttings curing agent provided by an embodiment of the present utility model. The quantitative filling device for oilfield drilling cuttings curing agent includes a belt conveyor 1, a feeding pipe fitting 2, a quantitative component 3, a lifting component 4, and a driving component 5.

[0029] In an embodiment of the present utility model, please refer to Figures 1 to 4 , a feeding pipe fitting 2 for filling the cuttings curing agent is installed on one side of the belt conveyor 1. The feeding pipe fitting 2 includes a guiding pipe 21. A branch pipe 22 is installed on the guiding pipe 21, and a feeding pipe 23 is installed on the branch pipe 22. A filling nozzle 25 is installed on the feeding pipe 23. One end of the guiding pipe 21 far from the mounting rod 31 is fixedly connected to the output end of a cuttings curing agent delivery pump. An elastic telescopic pipe 24 that is vertically downward and faces the belt is fixedly installed on the feeding pipe 23. The filling nozzle 25 is fixedly installed on the bottom pipe orifice of the elastic telescopic pipe 24;

[0030] A quantitative component 3 is installed on the guiding pipe 21. The quantitative component 3 includes a mounting rod 31. The mounting rod 31 is inserted into the guiding pipe 21 and fixedly installed with a piston 32 for sealing the branch pipe 22. Specifically, a fixing ring 34 is fixedly installed in the guiding pipe 21. A socket disc 35 is fixedly sleeved on the mounting rod 31, and a spring 36 is sleeved on the mounting rod 31. Two ends of the spring 36 are respectively fixedly connected to the fixing ring 34 and the socket disc 35. An auxiliary wheel A 33 with a rotational connection is installed at one end of the mounting rod 31 far from the piston 32 through a bracket. The quantitative filling device for oilfield drilling cuttings curing agent further includes a driving component 5 installed for driving the mounting rod 31 to reciprocate and slide along the guiding pipe 21.

[0031] It should be noted that: when the convex part of the quantitative cam 52 rotates in the direction away from the mounting rod 31, under the action of the elastic force of the spring 36, the socket disc 35 drives the mounting rod 31 to slide in the direction away from the feeding end of the guiding pipe 21. Therefore, the piston 32 on the mounting rod 31 slides away from the branch pipe 22. Thus, the material conveyed by the guiding pipe 21 enters the filling nozzle 25 through the feeding pipe 23 and is filled into the storage container by the filling nozzle 25, thereby completing the quantitative filling of one storage container. When the convex part of the quantitative cam 52 rotates in the direction of the mounting rod 31, the convex part of the quantitative cam 52 pushes the mounting rod 31 so that the piston 32 on the mounting rod 31 slides into the guiding pipe 21 in front of the branch pipe 22. Therefore, the branch pipe 22 is sealed, avoiding the potential risk of leakage of the filling nozzle 25 when the belt on the belt conveyor 1 conveys the next storage container to the lower part of the filling nozzle 25.

[0032] In an embodiment of the present utility model, please refer to Figures 1 to 4, the lifting component 4 includes a positioning carriage 41 which is fixedly installed on the feeding pipe 23. A lifting rod 42 is slidably connected and inserted into the positioning carriage 41. A middle connecting frame 44 is fixedly installed on the lifting rod 42, and the other end of the middle connecting frame 44 is fixedly installed on the filling nozzle 25. An auxiliary B wheel 43 is rotatably connected to the lower rod head of the lifting rod 42 through a bracket.

[0033] It should be noted that: when the convex part of the lifting cam 53 rotates to the upper side, the lifting rod 42 slides along the surface of the lifting cam 53 through the auxiliary B wheel 43. Therefore, the lifting rod 42 slides upward along the positioning carriage 41 and compresses the elastic telescopic pipe 24 through the middle connecting frame 44, so that the filling nozzle 25 slides out of the feeding port of the storage container. When the convex part of the lifting cam 53 deviates from the due upper side, the lifting rod 42 slides downward along the positioning carriage 41 and stretches the elastic telescopic pipe 24 through the middle connecting frame 44. Thus, the filling nozzle 25 slides downward until the next storage container moves below the filling nozzle 25, and then the filling nozzle 25 is inserted into the storage container for filling.

[0034] In the embodiment of the present utility model, please refer to Figures 1 to 4 , the driving component 5 includes a rotating shaft 51. A metering cam 52 and a lifting cam 53 are fixedly installed on the rotating shaft 51. The convex parts of the metering cam 52 and the lifting cam 53 are distributed at 90°. The metering cam 52 abuts against the auxiliary A wheel 33, and the lifting cam 53 abuts against the auxiliary B wheel 43. A middle connecting member 54 is also installed on the rotating shaft 51. The middle connecting member 54 includes a notch disk 541 which is fixedly installed on the rotating shaft 51 and coaxially arranged with the rotating shaft 51. A rocker arm 542 is fixedly installed on the notch disk 541. The rocker arm 542 is located at the notch of the notch disk 541, and a guiding column 543 is fixedly installed on the rocker arm 542. The middle connecting member 54 further includes an intermittent disk 544 which is fixedly installed on the runner in the belt conveyor 1 and coaxially arranged with the runner. A plurality of annularly distributed arc-shaped grooves 544a and guiding grooves 544b are formed on the intermittent disk 544. The arc-shaped grooves 544a and the guiding grooves 544b are staggered. The notch disk 541 is adapted to the arc-shaped grooves 544a formed on the intermittent disk 544. The oilfield drilling cuttings solidifying agent metering filling device further includes a reduction motor for driving the rotation of the rotating shaft 51, and the reduction motor is fixedly installed on one side of the bracket of the belt conveyor 1 through a frame.

[0035] It should be noted that: when the reduction motor is started to drive the metering cam 52 and the lifting cam 53 to rotate, when the notch disk 541 rotates one circle, the guiding column 543 slides into the guiding groove 544b to make the intermittent disk 544 rotate one-fourth of a circle.

[0036] In this solution, the opening and closing of the branch pipe 22 is controlled by the cooperation of the piston 32 and the spring 36 in the metering component 3 and the metering cam 52 in the driving component 5, ensuring that the filling volume is the same each time, avoiding overfilling or underfilling. The linkage design between the metering cam 52 and the auxiliary A wheel 33 further improves the accuracy and reliability of the metering control. Moreover, the driving component 5 drives the metering cam 52 and the lifting cam 53 to act synchronously through the rotating shaft 51, realizing the coordinated operation of the lifting of the filling nozzle 25 and the material filling, significantly improving the filling efficiency. The linkage design between the intermittent disk 544 and the belt conveyor 1 enables the storage container to move intermittently, ensuring that each container accurately stops at the filling position and realizing continuous automated production. The piston 32 seals the branch pipe 22 under the drive of the metering cam 52, effectively preventing the leakage of materials during container switching, reducing resource waste and environmental pollution. The design of the elastic telescopic pipe 24 enables the filling nozzle 25 to flexibly stretch and retract, further avoiding dripping during the filling process.

[0037] The working principle of the quantitative filling device for oilfield drilling cuttings curing agent provided by the present utility model is as follows:

[0038] The storage containers for storing the cuttings curing agent are successively placed on the belt. The reduction motor is started to drive the rotating shaft 51 to rotate, so that the guide posts 543 on the notch disk 541 are turned into the corresponding guide grooves 544b, driving the intermittent disk 544 to rotate a quarter of a circle. Therefore, the rotating wheels fixedly connected to the belt conveyor 1 rotate synchronously, causing the belt to move intermittently, and the storage containers placed on the belt can successively move to the lower part of the filling nozzle 25;

[0039] At the same time, the convex part of the lifting cam 53 rotates to a direction deviating from the axis of the lifting rod 42. Thus, the lifting rod 42 slides down along the positioning carriage 41 and stretches the elastic telescopic pipe 24 through the intermediate coupling frame 44, causing the filling nozzle 25 to be inserted into the feed port of the storage container. When the convex part of the lifting cam 53 rotates to the upper part, the lifting rod 42 slides along the surface of the lifting cam 53 through the auxiliary B wheel 43. Therefore, the lifting rod 42 slides up along the positioning carriage 41 and compresses the elastic telescopic pipe 24 through the intermediate coupling frame 44, causing the filling nozzle 25 to slide out of the feed port of the storage container.

[0040] When the convex part of the metering cam 52 rotates away from the mounting rod 31, under the action of the elastic force of the spring 36, the socket disc 35 drives the mounting rod 31 to slide away from the feeding end of the material guiding pipe 21. Therefore, the piston 32 on the mounting rod 31 slides away from the branch pipe 22. Thus, the material conveyed by the material guiding pipe 21 enters the filling nozzle 25 through the feeding pipe 23 and is filled into the storage container by the filling nozzle 25, thereby completing the metering filling of a storage container. When the convex part of the metering cam 52 rotates towards the mounting rod 31, the convex part of the metering cam 52 pushes the mounting rod 31, causing the piston 32 on the mounting rod 31 to slide into the material guiding pipe 21 in front of the branch pipe 22. Therefore, the branch pipe 22 is sealed, avoiding the potential risk of material leakage from the filling nozzle 25 when the belt on the belt conveyor 1 conveys the next storage container under the filling nozzle 25;

[0041] When the intermittent disc 544 rotates another quarter turn, the belt makes an intermittent movement, causing the next storage container to slide under the filling nozzle 25 for filling.

[0042] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0043] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
