Description

Technical Field

[0001] This utility model belongs to the field of rock cuttings collection and processing technology, specifically, it relates to a rock cuttings queuing and separating device. Background Technology

[0002] During well logging operations, after the cuttings are collected and cleaned, the cuttings samples are continuously fed into specialized automated cuttings collection and analysis equipment for analysis. This equipment can continuously analyze the cuttings samples, requiring the cuttings containers containing the samples to be placed on a conveyor to queue for the robotic arm to grasp. The cuttings containers are typically shallow, square boxes with a central cuttings-containing cavity. To ensure accurate grasping by the robotic arm, a blocking device is usually installed on the conveyor, allowing only one cuttings container to pass at a time. However, the queuing at the loading end results in almost no blocking gaps between containers, making effective blocking difficult. Secondly, the containers are lightweight, and accidental contact can easily knock them off. With the continuous conveyor operation, the blocking device may fail, allowing multiple cuttings containers to enter the grasping area. Ungrabbed containers will fall along the conveyor, leading to sample loss and affecting the overall progress of the cuttings analysis and the accuracy of the final results. Utility Model Content

[0003] The purpose of this invention is to provide a material box queuing and separation device to solve the problem that shallow and light square rock chip boxes cannot effectively prevent the loss of rock chip samples during transportation.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A material box queuing and separation device includes a rock cuttings box, a blocking device, and a conveying mechanism; the conveying mechanism transports the rock cuttings box from the inlet side to the outlet side; the blocking device is mounted on the conveying mechanism; the blocking device includes a cylinder support, cutting jaws, and a bidirectional drive device; the cylinder support is a gantry-type frame, and the bottom of the two side gantry frames of the cylinder support is fixedly connected to the two sides of the conveying mechanism; the top of the gantry frame of the cylinder support is equipped with a bidirectional drive device, which has a retractable left power end and a right power end, and the left power end and the right power end are respectively fixedly mounted with cutting jaws, and the bottom of the cutting jaws is respectively provided with blocking plugs extending in opposite directions;

[0006] The rock cuttings box is a square box with a placement cavity at the top. The four corners of the rock cuttings box are provided with rounded chamfers, and the side walls of the rock cuttings box are provided with horizontal slots.

[0007] Preferably, the bidirectional drive device uses a bidirectional cylinder.

[0008] Preferably, photoelectric switches are installed at both the inlet and outlet ends of the conveying mechanism.

[0009] Preferably, a limit bar is provided on the conveying mechanism located on the right side of the blocking device.

[0010] The beneficial technical effects of this utility model compared to the prior art are as follows:

[0011] This invention uses a bidirectional cylinder to drive the left and right cutting jaws to move in opposite directions, simultaneously inserting the blocking plug into the slots opened on the side wall of the rock cutting box from both sides. The precise positioning of the blocking plug in the slots completes the rapid blocking of the rock cutting box. The arc-shaped chamfers at the four corners of the rock cutting box provide a horizontal guide for the blocking plug, allowing it to slide into the slots more quickly, resulting in a shorter blocking stroke and a faster response. At the same time, the square shape of the rock cutting box facilitates the rapid positioning and gripping of the cutting jaws. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figure 1-3 As shown, this utility model provides a material box queuing and separation device; the specific implementation scheme is as follows:

[0018] The system includes a rock cuttings box 1, a blocking device 2, and a conveying mechanism 3. The conveying mechanism 3 transports the rock cuttings box 1 from the inlet side to the outlet side. The blocking device 2 is mounted on the conveying mechanism 3. The blocking device 2 includes a cylinder support 201, a cutting gripper 202, and a bidirectional drive device 203. The cylinder support 201 is a gantry-type frame, and the bottom of the two side frames of the cylinder support 201 is fixedly connected to the two sides of the conveying mechanism 3. The bidirectional drive device 203 is installed at the top of the gantry of the cylinder support 201. The bidirectional drive device 203 has a retractable left power end and a right power end. The left power end and the right power end are respectively fixedly mounted with the cutting gripper 202, and the bottom of the cutting gripper 202 is respectively provided with blocking plugs 204 extending in opposite directions.

[0019] The rock cuttings box 1 is a square box with a placement cavity 101 on the top. The four corners of the rock cuttings box 1 are provided with arc-shaped chamfers 102, and the side walls of the rock cuttings box 1 are provided with horizontal slots 103.

[0020] In use, the bidirectional drive device 203 activates, causing the left and right cutting jaws 202 to move towards each other.

[0021] The blocking plug 204 is inserted into the slot 103 on the side wall of the rock cuttings box 1 from both the left and right sides. The arc-shaped chamfers 102 at the four corners of the rock cuttings box 1 provide a horizontal guide for the blocking plug 204, which quickly and accurately positions the blocking plug 204 in the slot 103, thereby quickly blocking the rock cuttings box 1. This overcomes the problem that existing blocking devices are prone to knocking the rock cuttings box off the conveying track due to the large blocking action. The square shape of the rock cuttings box 1 is conducive to the quick positioning and gripping of the cutting claw 202, avoiding knocking over the rock cuttings box 1 and ensuring the stability of the rock cuttings box 1 on the conveying mechanism 3. At the same time, the bidirectional drive cutting claw 202 provided by the bidirectional drive device has a short stroke and acts more quickly.

[0022] It should be noted that the bidirectional drive device 203 uses a bidirectional acting cylinder. The bidirectional acting cylinder has a closed cylinder body, with the cylinder barrel divided into left and right working chambers to form pressure chambers, each guiding the linear motion of the piston within its working chamber. An air inlet is located at both the front and rear ends of the cylinder body. A sealing ring / buffer plunger is installed between the piston and the cylinder body to ensure chamber sealing and buffering effects. For ease of installation and maintenance, the cylinder barrel and end caps are often connected by tie rods, threads, flanges, or riveting. The bidirectional acting cylinder's "air inlet at both ends, piston subjected to bidirectional force" structure has the advantages of high thrust and high control precision.

[0023] See appendix Figures 1 to 2 As shown, a limit bar 4 is provided on the conveying mechanism 3 on the right side of the blocking device 2, which can accurately position the rock cuttings box 1 at the position of the conveying mechanism 3.

[0024] It should be noted that photoelectric switches are installed at both the inlet and outlet ends of the conveying mechanism 3. The photoelectric switches use a transmitter and a receiver to identify whether a rock cutting box has passed through. The photoelectric switch at the signal inlet end determines whether a certain number of rock cutting boxes are waiting in line on the conveying mechanism, and the photoelectric switch at the outlet end determines whether a rock cutting box is at the gripping position of the conveying mechanism. If a rock cutting box is detected, a signal is transmitted to the bidirectional drive device 203 to work, driving the cutting gripper 202 to move in opposite directions to block the conveying of the rock cutting box. If no rock cutting box is detected at the gripping position, the bidirectional drive device 203 opens the cutting gripper 202 to release the blockage of the rock cutting box conveying. This process is repeated to ensure that only one rock cutting box passes through the blocking device 2 at a time to wait for gripping.

[0025] It should be noted that a limit bar 4 is provided on the conveying mechanism 3 located on the right side of the blocking device 2; it limits the rock cuttings box 1 that passes through the blocking device 2, ensuring that the robotic arm of the rock cuttings analysis equipment can accurately grasp it.
