Description

Technical Field

[0001] This invention belongs to the technical field of ore mining equipment, specifically relating to an automatic ore collection device. Background Technology

[0002] In exploration or mineral resource development, drilling rigs are typically used to break the rock at the bottom of the borehole and lower or lower the drill bit into the hole to obtain physical geological data to investigate underground geology and mineral resources. To obtain accurate information from the drilling and adjust the plan in a timely manner, it is necessary to continuously collect and analyze drill particle samples during the drilling process. To reduce dust during the collection process, dust covers are usually used. To ensure the accuracy of the data and avoid residual sample particles remaining on the dust cover from affecting the data analysis results, the dust cover needs to be cleaned regularly.

[0003] In existing collection devices, the dust cover is usually cleaned together with the collection cylinder. Specifically, after the drilling sample particle collection is completed, the vacuum pump is turned off, and the air compressor is turned on by opening and closing the corresponding valves. The high-pressure gas generated by the air compressor blows off the residual particles in the dust cover and collection cylinder. The high-pressure air from the air compressor is then discharged from the collection device through the valves. In other words, the collection process needs to be interrupted for each dust removal process, and the collection work cannot be carried out continuously, resulting in low efficiency.

[0004] The existing technology is inadequate and further improvements are needed. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an automatic ore collection device to solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic ore collection device, comprising a dust cover and two collection cylinders. The dust cover is a frustum structure with an open lower end. The dust cover is equipped with an adjusting turntable, and a sleeve is fixed in the middle of the adjusting turntable. The lower end of the sleeve is at the same height as the lower edge of the dust cover, and the upper end of the sleeve extends out of the dust cover. The sleeve is rotatably connected to the middle of the upper side of the dust cover via a rolling bearing. A turbine fan is fixed to the upper end of the sleeve, and the sleeve is rotatably sleeved on the drill rod of a drilling rig. A first annular pipe and a second annular pipe are provided on the upper side of the dust cover, and two vacuum tubes and two compressed air pipes are symmetrically arranged on the left and right sides of the upper side of the dust cover. The lower ends of the vacuum tubes and compressed air pipes are connected to the dust cover, and the upper ends of the two vacuum tubes are connected through the first annular pipe. The system connects two air compressor pipes at their upper ends to a second annular pipe. A ring of nozzles is evenly distributed around the upper side of the second annular pipe, with the lower ends of the nozzles connected to the second annular pipe and pointing towards the turbine fan. A testing container is located below the collecting cylinder. The collecting cylinder has an inverted conical opening at its lower side, with a first valve at the opening. A first port is located on the upper side of the collecting cylinder. A second port and a third port are symmetrically arranged on the arc-shaped side of the collecting cylinder near its upper side. A second valve is installed on the first port, and a third valve is installed on the third port. Both the first port and the second annular pipe are connected to the air compressor via PVC steel wire pipes. The second port is connected to the vacuum pump via a PVC steel wire pipe, and the third port is connected to the first annular pipe via a PVC steel wire pipe.

[0007] Preferably, the adjusting turntable is provided with a semi-circular first arc-shaped through hole and a semi-circular second arc-shaped through hole, and the angles of the first arc-shaped through hole and the second arc-shaped through hole are staggered. The diameter of the first arc-shaped through hole is equal to the distance between the two vacuum tubes, and the diameter of the second arc-shaped through hole is equal to the distance between the two air compressor tubes.

[0008] Preferably, the dust cover has two partitions in the same vertical plane. The lower edge of the partition is at the same horizontal plane as the lower edge of the dust cover. One side edge of the partition is fixedly connected to the inner wall of the dust cover, and the other side edge of the partition is in contact with the sleeve. The side of the partition is tangent to the inner diameter of the vacuum tube and the air compressor tube.

[0009] Preferably, a filter screen is provided inside the first arc-shaped through hole.

[0010] Preferably, an isolation net is provided inside the second port.

[0011] The beneficial effects of this invention are as follows: The collecting cylinder of this invention includes three processes: collecting drilling sample particles, the sample particles flowing out of the collecting cylinder, and cleaning the collecting cylinder. The dust cover, divided into two parts by a partition, sequentially performs the drilling sample collection and dust cleaning processes. After the high-pressure gas generated by the air compressor enters the second ring pipe, a portion is directly blown onto the turbine fan, driving the adjusting turntable to rotate and adjust the positions of the first and second arc-shaped channels. Due to the partition, the uninterrupted collection process of drilling sample particles is achieved simultaneously with the dust cover cleaning, ensuring the continuity of drilling sample particle collection. The collecting cylinder collects drilling sample particles... When collecting sample particles, high-pressure gas generated by the air compressor enters from the first port and flows out from the port at the bottom of the collection cylinder, thus cleaning the collection cylinder. During the cleaning process, the third valve is closed, which shuts off the channel through which the vacuum pump cleans the collection cylinder to the dust cover, preventing drilling sample particles from entering the collection cylinder. The two collection cylinders are independent of each other, and the channel from the other collection cylinder to the dust cover is unaffected. Therefore, cleaning one collection cylinder does not affect the collection of drilling sample particles in the other collection cylinder, ensuring the continuity of drilling sample particle collection and improving work efficiency.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-3As shown, an automatic ore collection device includes a dust cover 1 and two collection cylinders 2. The dust cover 1 is a frustum structure with an open bottom. An adjusting turntable 3 is provided on the dust cover 1, and a sleeve 4 is fixed in the middle of the adjusting turntable 3. The lower end of the sleeve 4 is at the same height as the lower edge of the dust cover 1, and the upper end of the sleeve 4 extends out of the dust cover 1. The sleeve 4 is rotatably connected to the middle of the upper side of the dust cover 1 via a rolling bearing. A turbine fan 5 is fixed to the upper end of the sleeve 4, and the sleeve 4 is rotatably sleeved on the drill rod of a drilling rig. A first annular pipe 8 and a second annular pipe 9 are provided on the upper side of the dust cover 1. Two vacuum pipes 6 and two compressed air pipes 7 are symmetrically arranged on the left and right sides of the upper side of the dust cover 1. The lower ends of the vacuum pipes 6 and compressed air pipes 7 are connected to the dust cover 1, and the upper ends of the two vacuum pipes 6 are connected through the first annular pipe 8, and the upper ends of the two compressed air pipes 7 are connected through the second annular pipe 9. The second annular pipe 9 has nozzles 10 evenly distributed on its upper side. The lower end of the nozzles 10 is connected to the second annular pipe 9, and the upper end of the nozzles 10 points towards the turbine fan 5. A test container 12 is provided below the collection cylinder 1. The lower side of the collection cylinder 1 has an inverted conical opening structure. A first valve 13 is provided at the lower opening of the collection cylinder 1. A first port 14 is provided in the middle of the upper side of the collection cylinder 2. A second port 15 and a third port 16 are symmetrically provided on the arc-shaped side of the collection cylinder 2 near the upper side. A second valve 17 is provided on the first port 14, and a third valve 18 is provided on the third port 16. The first port 14 and the second annular pipe 9 are both connected to the air compressor through PVC steel wire pipes. The second port 15 is connected to the vacuum pump through PVC steel wire pipes. The third port 16 is connected to the first annular pipe 8 through PVC steel wire pipes.

[0018] In this embodiment, the adjusting turntable 3 is provided with a semi-circular first arc-shaped through hole 301 and a semi-circular second arc-shaped through hole 302, and the first arc-shaped through hole 301 and the second arc-shaped through hole 302 are offset at angles. The diameter of the first arc-shaped through hole 301 is equal to the distance between the two vacuum tubes 6, and the second arc-shaped through hole 302 is equal to the distance between the two air compressor tubes 7.

[0019] In this embodiment, two partitions 11 are provided inside the dust cover 1 in the same vertical plane. The lower edge of the partition 11 is at the same horizontal plane as the lower edge of the dust cover 1. One side edge of the partition 11 is fixedly connected to the inner wall of the dust cover 1, and the other side edge of the partition 11 is in contact with the sleeve 4. The side of the partition 11 is tangent to the inner diameter of the vacuum tube 6 and the air compressor tube 7.

[0020] In this embodiment, a filter screen is provided inside the first arc-shaped through hole 301 for filtering impurities.

[0021] In this embodiment, an isolation net is provided inside the second port 15 to prevent the particles collected in the collection cylinder 2 from entering the vacuum pump.

[0022] The working principle of this invention: In use, the collecting cylinder 2 includes three processes: collecting drilling sample particles, the sample particles flowing out of the collecting cylinder 2, and cleaning the collecting cylinder 2. The dust cover 1, divided into two parts by the partition 11, sequentially performs the drilling sample collection and dust cover 1 cleaning processes. After the high-pressure gas generated by the air compressor enters the second annular pipe 9, a portion is directly blown onto the turbine fan 5, driving the adjusting turntable 3 to rotate. When the first arc-shaped through hole 301 connects to the vacuum tube 6 on one side of the dust cover 1, the second arc-shaped through hole 302 connects to the air compressor tube 7 on the other side of the dust cover 1. Due to the obstruction of the partition 11, the high-pressure air in the second annular pipe 9... The air is blown into the corresponding side of the dust cover 1 through the air compressor pipe 7 to clean the corresponding area inside the dust cover 1. Meanwhile, the vacuum pump sequentially draws air from the other side of the dust cover through the collection cylinder 2, the third port 16, the first ring pipe 8, and the vacuum tube 6 to create a negative pressure, thereby collecting the drilling sample inside the dust cover 1 into the vacuum tube 6. Then, when collecting drilling sample particles in the collection cylinder 1, the high-pressure gas drives the turbine fan 5 to adjust the area of ​​drilling sample particle collection and cleaning inside the dust cover 1, so as to achieve the uninterrupted collection process of drilling sample particles while cleaning the dust cover 1, ensuring the continuity of drilling sample particle collection.

[0023] When collecting drilling sample particles in collection cylinder 1, the first valve 13 is closed, the second valve 17 is closed, and the third valve 18 is opened. The first port 14 of the air compressor's channel to collection cylinder 2 is closed, while the third port of the vacuum pump's channel to collection cylinder 2 is opened, drawing the drilling sample particles into collection cylinder 2. Then, during the process of sample particles flowing out of collection cylinder 2, the second valve 17 and the third valve 18 are closed, and the first valve 13 is opened, releasing the drilling sample particles from collection cylinder 2 into the analysis container. Finally, when cleaning collection cylinder 2, the second valve 17 is opened, the first valve 13 is opened, and the third valve 18 is closed. Valve 18 allows high-pressure gas generated by the air compressor to enter through the first port 14 and exit through the port at the lower end of the collection cylinder 2, thus cleaning the collection cylinder 2. During the cleaning process, the third valve 18 closes, shutting off the channel of the collection cylinder 2 being cleaned by the vacuum pump that is acting on the dust cover, preventing drilling sample particles from entering the collection cylinder 2. Since the two collection cylinders 2 are independent of each other, the channel of the other collection cylinder to the dust cover 1 is unaffected. Therefore, cleaning one collection cylinder 2 does not affect the collection of drilling sample particles in the other collection cylinder 2, ensuring the continuity of drilling sample particle collection and improving work efficiency.

[0025] Any modifications, equivalent substitutions, or improvements made within the scope of this invention should be included within the protection scope of this invention.
