[0006] A ball storage tube, vertically fixed on the frame, is used to store plugging balls;

[0007] A ball-discharging component, vertically fixed on the frame and staggered vertically below the ball-storing tube, is used to discharge the plugging balls for plugging the holes; and

[0008] The ball-carrying component is located between the ball storage tube and the ball release component, and is horizontally oscillating on the frame via a drive component; the ball-carrying component has a vertically penetrating channel;

[0009] The ball-carrying device has a first position and a second position; in the first position, the channel and the ball storage tube are connected, and the ball-releasing device closes the lower end of the channel, so that the plugged ball in the ball storage tube enters and remains in the channel;

[0010] In the second position, the channel and the ball release device are connected, and the ball transport device closes the lower end of the ball storage tube, so that the plugged ball in the channel enters the ball release device.

[0011] In one possible implementation, the ball-releasing component includes:

[0012] The ball-laying tube is vertically fixed on the frame.

[0013] The first baffle is horizontally fixed on the ball release tube and located below the ball handling component;

[0014] A ball guide slide is fixedly disposed between the ball release tube and the first baffle, and is used to guide the plugged ball in the ball transport component into the ball release tube;

[0015] In the first position, the first baffle closes the lower end of the channel; in the second position, the channel and the guide ball slide are connected, and the first baffle avoids the channel.

[0016] In one possible implementation, the ball-carrying component includes:

[0017] A ball-carrying tube is vertically fixed at the output end of the drive component and is used to accommodate at least one of the plugging balls.

[0018] The second baffle is horizontally fixed on the ball-driving tube;

[0019] In the first position, the ball-carrying tube and the ball-storage tube are connected, and the second baffle avoids the ball-storage tube; in the second position, the ball-carrying tube and the ball-releasing device are connected, and the second baffle closes the lower end of the ball-storage tube.

[0020] In one possible implementation, the driving component is operated by a control system, and the ball-releasing component is fixedly provided with a first proximity switch and a second proximity switch that are electrically connected to the control system.

[0021] When the ball-carrying device moves to a position detected by the first proximity switch, the first proximity switch sends a first electrical signal to the control system to stop the ball-carrying device at the first position.

[0022] When the ball-carrying device moves to a position detected by the second proximity switch, the second proximity switch sends a second electrical signal to the control system to cause the ball-carrying device to stop at the second position.

[0023] In one possible implementation, a first photoelectric switch electrically connected to the control system is fixedly provided on the ball-releasing component. The first photoelectric switch is used to detect whether the plugging ball falls into the ball-releasing component.

[0024] A second photoelectric switch, which is electrically connected to the control system, is fixedly installed on the ball-carrying device. The second photoelectric switch is used to detect whether the ball with the hole blocked has fallen into the ball-carrying device.

[0025] In one possible implementation, a third baffle is hinged to the top of the ball storage tube, the third baffle being used to close the ball storage tube;

[0026] A counterweight handle is fixedly mounted on the hinge shaft of the third baffle. The counterweight handle drives the third baffle to rotate by its own weight. When the third baffle closes the ball storage tube, the counterweight handle and the third baffle maintain balance.

[0032] The spring is fixed at both ends to the positioning ball and the hinge shaft respectively, and is always in a compressed state.

[0033] In one possible implementation, two limiting plates are fixedly provided on the ball-releasing component, and a limiting space is formed between the two limiting plates to restrict the ball-carrying component from swinging between the first position and the second position.

[0034] In one possible implementation, a tip is fixedly provided at the bottom end of the ball-releasing component, and a cutting tooth for piercing the ground is fixedly provided at the bottom end of the tip.

[0035] This utility model provides an automatic plugging device for vertical shaft drilling rigs. Compared with existing technologies, its advantages are as follows: During operation, the drive unit moves the ball-carrying component horizontally. When the ball-carrying component is in the first position, its vertically connected channel is connected to the ball storage tube, and simultaneously, the ball-releasing component seals the lower end of the channel. At this time, the plugging ball in the ball storage tube falls down along the channel under the action of gravity and remains in the channel, thus realizing the transfer of the plugging ball from the ball storage tube to the ball-carrying component, eliminating the need for manual removal of the plugging balls one by one.

[0036] Next, the drive unit continues to operate, causing the ball-carrying component to swing to the second position. At this point, the channel and the ball-releasing component are connected, and simultaneously, the ball-carrying component seals the lower end of the ball storage tube. The plugging ball remaining in the channel enters the ball-releasing component under gravity, and then the ball-releasing component discharges the plugging ball to plug the hole. The entire process is highly automated, requiring no direct manual contact for plugging operations, greatly reducing the workload of manual plugging, and avoiding workers operating in hazardous environments, effectively reducing the risk of operation.

[0043] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0044] Please see Figure 1 This invention provides an automatic plugging device for a vertical shaft drilling rig. The automatic plugging device for a vertical shaft drilling rig includes a frame 1, a ball storage pipe 2, a ball dispensing component 3, and a ball conveying component 4. The ball storage pipe 2 is vertically fixed on the frame 1 and is used to store plugging balls. The ball dispensing component 3 is vertically fixed on the frame 1 and is staggered vertically below the ball storage pipe 2 to discharge plugging balls for plugging. The ball conveying component 4 is located between the ball storage pipe 2 and the ball dispensing component 3, and is horizontally oscillating on the frame 1 via a driving component 5. The ball conveying component 4 has a vertically penetrating channel.

[0045] The ball-carrying component 4 has a first position and a second position. In the first position, the channel and the ball storage tube 2 are connected, and the ball release component 3 closes the lower end of the channel, allowing the plugged ball in the ball storage tube 2 to enter and remain in the channel. In the second position, the channel and the ball release component 3 are connected, and the ball-carrying component 4 closes the lower end of the ball storage tube 2, allowing the plugged ball in the channel to enter the ball release component 3.

[0046] After the vertical shaft drilling rig completes a drilling operation, the drive unit 5 drives the ball transport unit 4 to swing horizontally. When the ball transport unit 4 is in the first position, its vertically connected channel is connected to the ball storage tube 2, and at the same time, the ball release unit 3 seals the lower end of the channel. At this time, the plugging ball in the ball storage tube 2 falls into the channel of the ball transport unit 4 due to gravity and remains there, thus realizing the automatic transfer of the plugging ball from the ball storage tube 2 to the ball transport unit 4 without manual handling.

[0047] Subsequently, the drive unit 5 continues to operate, causing the ball-carrying component 4 to swing to the second position. At this time, the channel of the ball-carrying component 4 is connected to the ball-releasing component 3, and the ball-carrying component 4 seals the lower end of the ball storage tube 2. The plugging ball in the channel falls into the ball-releasing component 3, and is then discharged into the hole by the ball-releasing component 3, thus achieving automatic hole plugging. This device, through automated operation, greatly reduces the workload of manual hole plugging, lowers the risk of workers operating in hazardous environments, significantly improves hole plugging efficiency, and ensures the continuity of vertical shaft drilling operations.

[0048] In some embodiments, see Figure 2 and Figure 3 The ball-releasing component 3 includes a ball-releasing tube 31, a first baffle 32, and a ball-guiding slide 33. The ball-releasing tube 31 is vertically fixed to the frame 1. The first baffle 32 is horizontally fixed to the ball-releasing tube 31 and located below the ball-carrying component 4. The ball-guiding slide 33 is fixedly disposed between the ball-releasing tube 31 and the first baffle 32, used to guide the plugged ball from the ball-carrying component 4 into the ball-releasing tube 31. In the first position, the first baffle 32 closes the lower end of the channel. In the second position, the channel and the ball-guiding slide 33 are connected, and the first baffle 32 avoids the channel.

[0049] The ball release tube 31 is vertically fixed to the frame 1, allowing the plugging ball to be discharged vertically downwards along the ball release tube 31. The first baffle 32 is horizontally fixed to the ball release tube 31 and located below the ball transport component 4. When the ball transport component 4 is in the first position, the first baffle 32 can effectively seal the lower end of the channel of the ball transport component 4, thereby preventing the plugging ball from falling off prematurely and ensuring that the plugging ball remains in the channel of the ball transport component 4.

[0050] The ball guide slide 33 is located between the ball release tube 31 and the first baffle 32. When the ball transport component 4 swings to the second position, its channel connects with the ball guide slide 33, and the first baffle 32 avoids the channel. At this time, the plugging ball in the ball transport component 4 can fall into the ball guide slide 33, guiding the plugging ball into the ball release tube 31. This optimizes the transfer path of the plugging ball from the ball transport component 4 to the ball release tube 31, ensuring that the plugging ball smoothly enters the ball release tube 31 for plugging, and improving the accuracy and stability of the plugging ball delivery.

[0051] In some embodiments, see Figure 2 and Figure 3 The ball-carrying component 4 includes a ball-carrying tube 41 and a second baffle 42. The ball-carrying tube 41 is vertically fixed at the output end of the drive component 5 and is used to accommodate at least one plugged ball. The second baffle 42 is horizontally fixed on the ball-carrying tube 41. In the first position, the ball-carrying tube 41 is connected to the ball storage tube 2, and the second baffle 42 avoids the ball storage tube 2. In the second position, the ball-carrying tube 41 is connected to the ball release component 3, and the second baffle 42 closes the lower end of the ball storage tube 2.

[0052] The ball-carrying tube 41 is vertically fixed to the output end of the drive unit 5 and swings under the drive of the drive unit 5, thereby realizing the transfer of the plugged ball from the ball storage tube 2 to the ball release unit 3. It should be understood that the ball-carrying tube 41 can hold one or more plugged balls, and the specific number that can be held is determined according to the size of the ball-carrying tube 41 itself.

[0053] In the first position, the ball-carrying tube 41 is connected to the ball-storage tube 2, and the second baffle 42 avoids the ball-storage tube 2, allowing the plugged ball in the ball-storage tube 2 to smoothly enter the ball-carrying tube 41. In the second position, the ball-carrying tube 41 is connected to the ball-releasing device 3, and at the same time, the second baffle 42 moves to close the lower end of the ball-storage tube 2, preventing other plugged balls in the ball-storage tube 2 from falling out at this time, ensuring that only the plugged ball in the ball-carrying tube 41 enters the ball-releasing device 3.

[0054] In some embodiments, see Figure 2 and Figure 3The drive unit 5 operates through a control system. A first proximity switch 61 and a second proximity switch 62, electrically connected to the control system, are fixedly installed on the ball-carrying component 3. When the ball-carrying component 4 moves to a position detected by the first proximity switch 61, the first proximity switch 61 sends a first electrical signal to the control system, causing the ball-carrying component 4 to stop at a first position. When the ball-carrying component 4 moves to a position detected by the second proximity switch 62, the second proximity switch 62 sends a second electrical signal to the control system, causing the ball-carrying component 4 to stop at a second position.

[0055] When the ball carrier 4 moves to the point where it is detected by the first proximity switch 61, the first proximity switch 61 sends a first electrical signal to the control system. The control system controls the ball carrier 4 to stay at the first position according to the first electrical signal, so as to ensure that the ball blocking the hole accurately enters and remains in the channel of the ball carrier 4.

[0056] When the ball-carrying component 4 moves to a position detected by the second proximity switch 62, the second proximity switch 62 sends a second electrical signal to the control system. Based on this signal, the control system controls the ball-carrying component 4 to stop at the second position, ensuring the plugging ball smoothly enters the ball-releasing component 3 from the ball-carrying component 4. Through the cooperation of the first proximity switch 61, the second proximity switch 62, and the control system, the positioning of the ball-carrying component 4 at the first and second positions is achieved, improving the accuracy and stability of the automated operation of the device, reducing manual intervention, and further enhancing the plugging efficiency.

[0057] In some embodiments, see Figure 2 and Figure 3 A first photoelectric switch 63, electrically connected to the control system, is fixedly installed on the ball-releasing component 3. The first photoelectric switch 63 is used to detect whether the ball with the blocked hole falls into the ball-releasing component 3. A second photoelectric switch 64, electrically connected to the control system, is fixedly installed on the ball-carrying component 4. The second photoelectric switch 64 is used to detect whether the ball with the blocked hole falls into the ball-carrying component 4.

[0058] The first photoelectric switch 63 on the ball-releasing device 3 is electrically connected to the control system and is used to detect whether the plugging ball has fallen into the ball-releasing device 3. When the plugging ball falls into the ball-releasing device 3, the first photoelectric switch 63 sends a signal back to the control system, so that the operator can understand the release status of the plugging ball in real time.

[0059] The second photoelectric switch 64 on the ball transport component 4 is also electrically connected to the control system and is used to detect whether the plugging ball has fallen into the ball transport component 4. This detection function ensures that the operator can keep track of the position of the plugging ball in a timely manner during the process of transferring the plugging ball from the ball storage tube 2 to the ball transport component 4. This helps to detect abnormalities in the process of transporting the plugging ball in a timely manner so that measures can be taken promptly to ensure the smooth progress of the plugging operation.

[0060] In some embodiments, see Figure 2A third baffle 71 is hinged to the top of the ball storage tube 2, and the third baffle 71 is used to close the ball storage tube 2. A counterweight handle 72 is fixedly installed on the hinge shaft 711 of the third baffle 71. The counterweight handle 72 pushes the third baffle 71 to rotate by its own weight. When the third baffle 71 closes the ball storage tube 2, the counterweight handle 72 and the third baffle 71 maintain balance.

[0061] The third baffle 71, hinged to the top of the ball storage tube 2, can close the ball storage tube 2 to prevent external debris from entering the ball storage tube 2 and affecting the quality of the plugged ball or causing blockage. The counterweight handle 72, fixed on the hinge shaft 711 of the third baffle 71, pushes the third baffle 71 to rotate by its own weight. When the third baffle 71 closes the ball storage tube 2, the counterweight handle 72 and the third baffle 71 maintain balance, so that the third baffle 71 is stably in the closed state.

[0062] When it is necessary to add a plugging ball to the ball storage tube 2, the plugging ball can be placed at the top of the ball storage tube 2. The weight of the plugging ball can push open the third baffle 71, allowing the plugging ball to enter the ball storage tube 2. After the plugging ball enters the ball storage tube 2, the counterweight handle 72 can drive the third baffle 71 to rotate by its own weight, so that the third baffle 71 re-closes the ball storage tube 2.

[0063] In some embodiments, see Figure 2 and Figure 4 A positioning plate 73 is fixedly mounted on the ball storage tube 2 around the hinge shaft 711. The positioning plate 73 has a first groove 731 and a second groove 732. An elastic positioning element 74 is provided on the hinge shaft 711, and the elastic positioning element 74 has an elastic degree of freedom to move toward the positioning plate 73. When the elastic positioning element 74 is engaged with the first groove 731, the third baffle 71 closes the ball storage tube 2. When the elastic positioning element 74 is engaged with the second groove 732, the third baffle 71 opens the ball storage tube 2.

[0064] A positioning plate 73, fixed around the hinge shaft 711 on the ball storage tube 2, has a first groove 731 and a second groove 732 that engage with an elastic positioning element 74 on the hinge shaft 711. When the elastic positioning element 74 engages with the first groove 731, the third baffle 71 closes the ball storage tube 2, and due to the engaging action of the elastic positioning element 74, the third baffle 71 can stably maintain a closed state, preventing accidental opening. When it is necessary to open the third baffle 71, the elastic force of the elastic positioning element 74 is overcome, causing it to disengage from the first groove 731. The third baffle 71 is then rotated until the elastic positioning element 74 engages with the second groove 732, at which point the third baffle 71 opens the ball storage tube 2.

[0065] In some embodiments, see Figure 4The elastic positioning element 74 includes a positioning ball 741 and a spring 742. The positioning ball 741 is slidably disposed on the hinge shaft 711 along the radial direction of the hinge shaft 711. The two ends of the spring 742 are fixed to the positioning ball 741 and the hinge shaft 711 respectively, and are always in a compressed state.

[0066] When the third baffle 71 rotates to the corresponding position, the positioning ball 741 is engaged in the first groove 731 or the second groove 732 under the elastic force of the spring 742, thereby locking the position of the third baffle 71, thus ensuring the stability of the third baffle 71 when closing or opening the ball storage tube 2, and ensuring the reliability of the state of the ball storage tube 2.

[0067] In some embodiments, see Figure 2 and Figure 3 Two limiting plates 8 are fixedly installed on the ball-laying component 3, forming a limiting space between the two limiting plates 8 to restrict the swing of the ball-carrying component 4 between the first position and the second position. During the swinging process of the ball-carrying component 4 driven by the driving component 5, the limiting plates 8 ensure that the ball-carrying component 4 can only swing within the set range, avoiding collisions with other components or affecting the normal delivery of the plugged ball due to excessive swinging.

[0068] In some embodiments, see Figure 2 and Figure 3 The bottom end of the ball-releasing component 3 is fixedly equipped with a tip 91, and the bottom end of the tip 91 is fixedly equipped with a cutting tooth 92 for penetrating the ground. At the shaft drilling rig operation site, the ground may be relatively soft or uneven. The cutting tooth 92 penetrating the ground provides stable support for the ball-releasing component 3, enhancing the connection stability between the ball-releasing component 3 and the ground. This ensures that when the plugging ball is discharged through the ball-releasing component 3, it accurately falls into the drilling location, improving the accuracy and reliability of plugging and guaranteeing the stable operation of the automatic plugging device for the shaft drilling rig under different ground conditions.

[0069] In summary, the automatic plugging device for vertical shaft drilling rigs provided by this utility model, compared with the prior art, involves the drive component 5 driving the ball-carrying component 4 to swing horizontally during operation. When the ball-carrying component 4 is in the first position, its vertically penetrating channel connects with the ball storage tube 2, while the ball-releasing component 3 seals the lower end of the channel. At this time, the plugging balls in the ball storage tube 2 fall down along the channel under the action of gravity and remain in the channel, thus realizing the transfer of the plugging balls from the ball storage tube 2 to the ball-carrying component 4, eliminating the need for manual removal of the plugging balls one by one.

[0070] Next, the drive unit 5 continues to operate, causing the ball-carrying unit 4 to swing to the second position. At this time, the channel and the ball-releasing unit 3 are connected, and the ball-carrying unit 4 seals the lower end of the ball storage tube 2. The plugging ball remaining in the channel enters the ball-releasing unit 3 under the action of gravity, and then the ball-releasing unit 3 discharges the plugging ball to plug the hole. The entire process is highly automated, requiring no direct manual contact for plugging operations, greatly reducing the workload of manual plugging, and avoiding workers operating in hazardous environments, effectively reducing the risk of operation.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
