Description

Technical Field

[0001] The present invention relates to the technical field of exploration coring equipment, in particular to a sand mine coring equipment. Background Art

[0002] Placer coring equipment is a crucial tool in geological exploration and mineral assessment. It is used to collect core samples from placer deposits. Widely used in geological exploration, mineral assessment, and scientific research, it effectively captures underground placer information and provides a scientific basis for resource development. Most existing equipment uses a power unit to control the rotation and thrust of the drill bit. After the drill bit cuts through the soil, a coring tube is used to contain and store the core material.

[0003] In order to avoid the fragments from flying out and injuring people during drilling operations, technical personnel in this field have conducted research and improvements. For example, an automatic coring device for land engineering with application number 202422279284.4 is provided. This technical solution sets a bucket-shaped protective cover on the outside of the coring barrel. The spring and guide rod ensure that the bucket-shaped protective cover is always in contact with the ground during drilling operations, thereby protecting and enclosing the fragments generated during drilling operations and preventing the fragments from splashing and injuring people. However, this technical solution only relies on friction to store the core material in the coring barrel. When the core material is loose, it is easy to fall off from the lower end. When the core material is dense, it is not suitable to be removed from the coring barrel, which affects the coring effect. For this reason, we have proposed a sand mine coring equipment.

[0048] The specific implementation of this embodiment is as follows:

[0049] When the device is in use, the base frame 1 can be moved on a flat road surface by using the moving wheels 2, and the device can also be fixed to a crawler loading device by using the anchor bolts 102 for overall movement to meet the use requirements of different terrains.

[0050] The bevel gear 1207 is driven to rotate by the driving motor 1206, and the bevel gear 1207 engages with the transmission bevel gear ring 1301, so that the driving cylinder 13 rotates in the workbench 12, and the assembly vertical rod 14 and the coring shell 15 rotate synchronously therewith.

The coring shell 15 is drilled into the sand mine soil through the base frame 1, which facilitates the coring work.

[0051] During the coring process, a liquid pump 302 is used to extract water from the water storage chamber 301, and the water is sent out by the nozzle 1203 at the end of the liquid supply pipe 1204, which can cool the coring shell 15. The dust cover 1202 is mounted on the outside of the coring shell 15, and the overall length of the elastic telescopic rod 1201 is variable, which can make the dust cover 1202 close to the surface during coring, reducing dust splashing and ensuring a safe and orderly working environment.

[0052] Example 2

[0053] On the basis of Example 1, the center rotation of the outer shell 1205 is connected to the outer sleeve 1251, the top of the outer shell 1205 is connected to the electromagnet 1252 and the limit rod 1253, the outside of the limit rod 1253 is provided with a metal lifting plate 1254, and a return spring 1255 is connected between the metal lifting plate 1254 and the upper end of the limit rod 1253.

The lower part of the outer wall of the outer sleeve 1251 is connected to a spur gear 12512, and the top of the inner cavity of the outer shell 1205 is connected to a horizontal electric push rod 12513, and the output end of the horizontal electric push rod 12513 is connected to a spur rack 12514, which is meshed with the spur gear 12512. By using the limiting slide 12561 in conjunction with the guide groove 12511, the outer sleeve 1251 and the hollow insertion rod 1256 rotate synchronously without affecting the vertical movement of the hollow insertion rod 1256.

[0056] The lower end of the core removal shell 15 is provided with a drilling tooth 1501, the center of the core removal shell 15 is provided with a core material channel 1502, the core removal shell 15 is provided with a transmission chamber 1503, and a plurality of double-headed screws 1504 are rotatably connected in the transmission chamber 1503. The upper and lower sections of the double-headed screw 1504 are arranged in opposite directions. The bottom of the outer wall of the double-headed screw 1504 is connected to a sprocket 1505. The outer walls of the plurality of sprockets 1505 are jointly sleeved with a transmission chain 1506. The upper end of the left double-headed screw 1504 is connected to a driven gear 1507, the outer wall of the double-headed screw 1504 is symmetrically screwed with a nut seat 1508, and a material cutting groove 1509 is connected between the transmission cavity 1503 and the core material channel 1502. The inner wall of the material cutting groove 1509 is connected with a sealing ring 1510 on the upper and lower sides. A plurality of core cutting plates 1511 are abutted between the two sealing rings 1510, and a traction rod 1512 is hinged between the end of the core cutting plate 1511 and the nut seat 1508. The core cutting plate 1511 can be extended into the core material channel 1502 to intercept the core material.

[0057] There are six double-headed screws 1504 and six core cutting plates 1511. The total angle of the six core cutting plates 1511 extending into one end of the core material channel 1502 is 360 degrees. When the six core cutting plates 1511 are inserted at the same time and form a circle, a good intercepting effect can be achieved to prevent the core material from falling off.

[0058] The specific implementation of this embodiment is as follows:

[0059] In this embodiment, when the coring shell 15 rotates, the drilling teeth 1501 perform a drilling operation on the soil, and the core material enters the core material channel 1502 in the middle of the coring shell 15. When the preset coring depth is reached, the electromagnet 1252 is energized, and the electromagnet 1252 magnetically attracts the metal lifting plate 1254. The length of the return spring 1255 increases, and the hollow insertion rod 1256 descends synchronously with the metal lifting plate 1254. The material stop block 1257 descends to block the upper end of the core material channel 1502. At this time, the gear ring 12571 contacts the teeth of the driven gear 1507.

[0060] The lateral electric push rod 12513 drives the spur rack 12514 to move horizontally. The spur rack 12514 engages with the transmission spur gear 12512, causing the outer sleeve 1251 to rotate. The guide groove 12511 cooperates with the limiting slide 12561 to limit and guide. The hollow insert rod 1256 can rotate with the outer sleeve 1251. The gear ring 12571 engages with the teeth of the driven gear 1507, thereby causing the driven gear 1507 to rotate, and a set of double-headed screws 1504 to rotate accordingly.

[0061] The multiple sprockets 1505 cooperate with the transmission chain 1506 to drive the multiple double-headed screws 1504 to rotate synchronously. The upper and lower nut seats 1508 move closer to each other. After the traction rod 1512 is deflected, the core cutting plate 1511 extends into the core material channel 1502 along the cutting groove 1509, which can cut off the core material in the core material channel 1502 to prevent it from falling off.

[0062] After the coring is completed, the conveying motor 7 is controlled to reverse so that the lower end of the coring shell 15 is higher than the receiving plate 107. After the winding discharge motor 304 is controlled to reverse, the compression spring 105 drives the sliding sleeve 104 to reset. The left cylindrical material box 178 is directly below the core material channel 1502. After the horizontal electric push rod 12513 is reset, the core cutting plate 1511 moves out of the material cutting groove 1509. After the air pump 12574 is started, the air flow enters the pipe joint 12576 along the air pipe 12575, and then enters the folded airbag 12572 along the hollow insertion rod 1256. After the overall volume of the folded airbag 12572 increases, the extrusion plate 12573 squeezes the core material out of the core material channel 1502. The cylindrical material box 178 can effectively preserve the core material, which is convenient for subsequent removal and related project testing.
