[0020] The core of the utility model is to provide a closed cuttings conveying device, which can convey the cuttings to the vehicle in a closed manner, solve the environmental protection problem in the process of loading drilling fluid waste materials, and reduce equipment costs and labor costs.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a closed rock cuttings conveying device. Figure 1 As shown, Figure 1 The utility model provides a schematic diagram of an embodiment of a closed rock cuttings conveying device, which may include a receiving container 1, a control component 2, and a liquid pumping component 3, a rock cuttings moving component 4 and a rock cuttings pumping component 5, all of which are connected to the control component 2 in a communication manner, wherein the receiving container 1 is used to receive waste to be conveyed including liquid and rock cuttings, the liquid pumping component 3 is used to obtain the liquid in the receiving container 1 and pump it under the control of the control component 2, and the rock cuttings moving component 4 is used to open and extend into the receiving container 1 under the control of the control component 2 to pump the rock cuttings into the receiving container 1. The cuttings are moved to the cuttings pumping component 5, which can be placed at the bottom of one end of the receiving container 1, and can preferably be connected to the inner compartment of the receiving container 1 through a flange to receive the cuttings, and is used to pump the cuttings under the control of the control component 2. It can be seen that the cuttings moving component 4 and the cuttings pumping component 5 are organically coordinated, one is responsible for movement, and the other is responsible for loading. The discharge port of the cuttings pumping component 5 can be inside the vehicle compartment, so that it can remain motionless throughout the loading process, unlike an excavator that moves with the cuttings continuously, thereby not causing the cuttings to be scattered to the external environment.

[0023] It should be noted that the above-mentioned receiving container 1 can specifically adopt a receiving tank, which is placed next to the solid control equipment as a temporary storage container, and multiple receiving tanks can be connected according to actual needs to form a larger receiving container to receive more waste to be transported. The purpose is to improve the ability to temporarily store drilling fluid waste when the transportation vehicles are not timely. Moreover, its bottom can be preferably a sloped structure, and the bottom height gradually decreases towards the position of the cuttings pumping component, so that more cuttings can be naturally moved to the position of the cuttings pumping component under the action of gravity, and it is also convenient for the cuttings moving component to move the cuttings, which is more labor-saving. After the waste to be transported is left in the receiving container 1 for a period of time, under a natural state, the liquid with good fluidity will be located in the upper layer, and the cuttings will settle to the lower part and solidify, and the drier cuttings in the lower part can be moved by the cuttings moving component to the cuttings pumping component, which provides a basis for separate transportation. The above-mentioned control component 2 can select its installation position according to actual needs, and can be installed on the cuttings moving component 4, which can be preferably anti- Explosion control cabinet, to improve safety performance, of course, it can also be installed separately in other places, there is no restriction here, and it can be connected to the liquid pumping component 3 and the cuttings pumping component 5 by wireless mode, so that too many control lines on site can be avoided, causing safety hazards, of course, it can also be connected by wire, and the control line can be hidden underground, which can be set according to actual needs. In addition, multiple buttons can be set on this control component 2, one of which can be used to control the movement of the cuttings moving component itself and the grabbing of cuttings, and the other buttons can be used to control the opening or closing of the liquid pumping component 3 and the cuttings pumping component 5 after the vehicle is in a suitable position, so as to transport the liquid and cuttings to the vehicle in a closed manner, and separate transportation can be achieved, that is, the liquid is transported to one vehicle, and the cuttings are transported to another vehicle, the two do not affect each other, and they will not fall to the ground, so as to meet the environmental protection requirements, the whole device has a stronger degree of automation, and there is no need for the driver to drive the excavator to load the vehicle, so that the labor cost and the car rental cost are saved.

[0024] When the above device is used specifically, the drilling fluid waste is precipitated in the receiving container, the liquid pumping component is started, and the surface water or mud with good fluidity is pumped to the transport vehicle box, and then the rock cuttings moving component is operated to move the rock cuttings precipitated in the lower layer to the feed port of the rock cuttings pumping component, and the rock cuttings pumping component is started at the same time to pump the rock cuttings to the transport vehicle box. It can be seen that the device can transfer the precipitated rock cuttings to the feed port of the rock cuttings pumping component by means of flat scraping or digging of the rock cuttings moving component, which can ignore the easy precipitation characteristics of the drilling fluid waste, and can also make up for the disadvantage of the rock cuttings pumping component without self-priming ability, so as to realize the closed transportation of the drilling fluid waste, avoid the environmental risks when loading the drilling fluid waste, and at the same time reduce the number of operators and the rental cost of an excavator, and has high environmental value and economic value.

[0025] It can be seen from the above technical scheme that in the embodiment of the above-mentioned closed rock cuttings conveying device provided by the utility model, since it includes a receiving container 1, a control component 2, and a liquid pumping component 3, a rock cuttings moving component 4 and a rock cuttings pumping component 5, all of which are communicatively connected to the control component 2, wherein the receiving container 1 can be arranged below the mud tank sand trough for receiving waste to be conveyed including liquid and rock cuttings, the liquid pumping component 3 is used to obtain the liquid in the receiving container 1 and pump it under the control of the control component 2, and the liquid pumping component 3 can preferably be a sand pump, and the rock cuttings moving component 4 is used to open and extend into the receiving container under the control of the control component 2. The rock cuttings are moved to the rock cuttings pumping component 5 in the device 1. The rock cuttings pumping component 5 is used to pump the rock cuttings under the control of the control component 2. The rock cuttings pumping component 5 can preferably be a rock cuttings pump. It can be seen that this solution can directly transport the liquid to the vehicle in a closed manner, or it can move the rock cuttings to the position of the rock cuttings pumping component and then directly pump it to the vehicle. It will not come into contact with the outside world and cause pollution. The whole process can be completed automatically by the device, reducing human participation, and there is no need for people to drive excavators for loading. It can be seen that this solution can transport the rock cuttings to the vehicle in a closed manner, solve the environmental protection problems in the process of loading drilling fluid waste materials, and reduce equipment costs and labor costs.

[0026] In a specific embodiment of the above-mentioned closed cuttings conveying device, continue to refer to Figure 1, and may also include a lifting component 6 that is communicatively connected to the control component 2, the liquid pumping component 3 is mounted on the lifting component 6, and the lifting component 6 is used to lower the liquid inlet of the liquid pumping component 3 to extend below the liquid level in the receiving container 1 or to rise to leave the liquid in the receiving container 1. Specifically, the lifting component 6 can be mounted on the surface of the receiving container, specifically a crane, and the liquid pumping component can be a sand pump, and the sand pump can be stably suspended on the crane, so that the height of the suction port of the sand pump and the position of the sand pump can be adjusted according to actual conditions to achieve the best suction effect. When the liquid level is relatively high, the position of the sand pump can be raised, and when the liquid level is low, the position of the sand pump is correspondingly lowered to avoid sucking in air, and the position cannot be so low as to enter the cuttings layer to avoid sucking in cuttings and causing pipeline blockage.

[0027] In another specific embodiment of the above-mentioned closed cuttings conveying device, continue to refer to Figure 1 The above device may further include a track 7 disposed on the receiving container 1, and the cuttings moving component 4 may be movably disposed on the track 7. The cuttings moving component 4 may preferably be located on the inner side of the track 7, and the cuttings moving component 4 may have the function of stopping and positioning at any position in the track 7, and the cuttings may be moved to the feed port of the cuttings pumping component by moving on the track 7 to be pumped into the vehicle compartment. It can be seen that after adopting such a track 7, the moving path of the cuttings moving component 4 can be better limited to ensure that it will not move to the surrounding position, and the moving speed can also be increased.

[0028] In another specific embodiment of the above-mentioned closed rock cuttings conveying device, the rock cuttings moving component 4 can preferably be a feeding robot. It should be noted that this feeding robot can have the function of rotating around the center of the base and rotating to limit the position, can work in two directions, front and back, and can limit the rotation angle to avoid excessive rotation. Moreover, this feeding robot can dig up the drilling fluid waste and transport it to the feed port of the rock cuttings pumping component 5 by loading or scraping. Not only is the excavation efficiency higher, the movement efficiency is also higher, and no manual operation is required, thereby making the working efficiency of the entire device higher.

[0029] In a preferred embodiment of the above-mentioned closed cuttings conveying device, reference Figure 2 , Figure 2Schematic diagram of the internal composition of the cuttings moving component, the control component 2 can preferably be a field control unit 41 arranged on the cuttings moving component 4, and the cuttings moving component 4 can also specifically include a power unit 42, a hydraulic self-propelled unit 43 with a guide mechanism and a locking mechanism, and a mechanical arm unit 44, all of which are connected to the field control unit 41 for communication, the hydraulic self-propelled unit 43 can move along the track in the longitudinal direction of the receiving container, the mechanical arm unit 44 is also connected to the bucket unit 45, wherein the power unit 42 is used to provide power for the hydraulic self-propelled unit 43 and the mechanical arm unit 44, specifically, a motor can be used to provide motive force for the hydraulic system, and the hydraulic system can provide power for the hydraulic cylinder to push the cuttings pumping component 5, the field control unit 41 is used to control the hydraulic self-propelled unit 43 to move to the target position and to control the mechanical arm unit 44 to use the bucket unit 45 to dig up the cuttings and move them to the cuttings pumping component 5, it can be seen that the cuttings conveying function can be better realized by using this compact structure, and the edge of the bucket unit 45 can be provided with rollers to prevent scratching the bottom plate of the receiving container, thereby forming a better protection effect.

[0030] In another preferred embodiment of the above-mentioned closed cuttings conveying device, Figure 3 , Figure 3 4 is a schematic diagram of the control structure in another preferred embodiment of the closed rock cuttings conveying device. It can be seen that the rock cuttings moving component 4 can also include an image acquisition unit 46 for acquiring the position and movement of the mechanical arm unit 44 and the bucket unit 45, and the on-site control unit 41 is communicatively connected to the remote control unit 47. The remote control unit 47 is also connected to an image display unit 48. The image display unit 48 is used to display the image acquired from the image acquisition unit 46 to achieve auxiliary remote control. Specifically, the on-site control unit 41 can acquire the image from the image acquisition unit 46 and transmit it to the remote control unit 47, and the remote control unit 47 then transmits the image to the image display unit 48. The image display unit 48 can be a liquid crystal screen, on which the current position and movement of the mechanical arm unit and the bucket unit can be displayed, so that the remote control personnel can intuitively see the current situation. Moreover, the remote control unit 47 is used to receive the remote control personnel's instructions and transmit them to the on-site control unit 41 to achieve remote control. Specifically, the remote control personnel can give an instruction by pressing a certain control button, and the remote control unit 47 transmits the instruction to the on-site control unit 41, and the on-site control unit 41 sends the instruction to the corresponding control object to perform the corresponding operation. It can be seen that this realizes long-distance visual automated operation, which can effectively improve the working environment of workers. Without the need for personnel to be on site, the threat to the health of operators caused by the harsh environment of the production site can be avoided.

[0031] In further embodiments, continue to refer to Figure 3 , the remote control unit 47 and the image display unit 48 can be preferably arranged on a wireless remote operation handle 49, and the wireless remote operation handle 49 can be a handle that can remotely control the rock cuttings moving component. This solution is to add some corresponding switch buttons on the original handle and make some improvements at the communication level, so as to make full use of the existing equipment for improvement, thereby further saving costs. In a further embodiment, the field control unit 41 can be connected to a first wireless signal transceiver unit, and the remote switch button on the remote control unit 47 can be connected to a second wireless signal transceiver unit. The second wireless signal transceiver unit is connected to the first wireless signal transceiver unit to realize remote opening and remote closing of the liquid pumping component 3 and the rock cuttings pumping component 5, as well as remote control of the rock cuttings moving component 4. This wireless communication method can avoid complex lines and can rely on high-speed communication methods to achieve rapid signal transmission.

[0032] In another preferred embodiment of the above-mentioned closed cuttings conveying device, continue to refer to Figure 1 The cuttings outlet of the cuttings pumping component 5 can also be connected to a discharge manifold 8 for guiding the cuttings to the outside. One end of the discharge manifold 8 can be connected to the cuttings outlet, and the other end can be directly connected to the vehicle compartment, so that the cuttings can be better prevented from splashing into the external environment. A hopper 9 can also be included, and the cuttings inlet of the cuttings pumping component 5 is arranged below the hopper 9, so that it is more convenient to allow the cuttings to enter the cuttings pumping component 5. It should also be noted that the hopper 9 can be at the end of the receiving container 1, with an open mouth at the same height as the upper plane of the receiving container 1, the side is connected to the receiving container 1, and the bottom can be connected to the inlet of the cuttings pumping component 5. It can be seen that the hopper 9 is equivalent to an intermediate connecting piece between the cuttings pumping component 5 and the receiving container 1, which can allow all the cuttings to enter the cuttings pumping component 5 without overflowing to the outside, thereby making the environmental protection effect of the entire device better.
