DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0029] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] First, connect the pneumatic gun to the core drill bit 2, open a large circular platform in the rock layer where sampling is required, replace the deep hole drill bit 1 to trim the platform, fix the connecting piece 6 to the pneumatic gun, and insert the raised ring 7 into the trimmed platform, and use the deep hole drill bit 1 to drill a hole. During the drilling process, the powder is brought to the inside of the collecting sleeve 3 by the lead groove 102 and rubbed with the steel brush 13 to fall into the collecting bottle 9, so that the powder can be directly collected after coming out of the sampling hole to avoid impurities entering and affecting the detection.

[0031] In the related art, powder is collected by a vacuum cleaner. As the powder falls to the ground, the vacuum cleaner will collect impurities such as dust and stones on the ground during the adsorption process, which will increase the impurity content and thus cause the grade of the sampled mineral to decrease, making it impossible to determine the actual grade.

[0032] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a metal ore sampling device. When it needs to be used, it is only necessary to first trim a platform for receiving the collection sleeve 3 and connect the collection sleeve 3 to the platform, and then sample through the deep hole drill bit 1, so that sampling can be carried out in time.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figure 1-Figure 5 The embodiment of the present application provides a metal ore sampling device, including a deep hole drill bit 1 and a coring drill bit 2. The outer surface of the deep hole drill bit 1 is sleeved with a collecting sleeve 3, and limiting rods 4 are fixedly installed on both sides of the outer surface of the collecting sleeve 3. The outer surface of the limiting rods 4 is sleeved with a reset spring 5, and the two reset springs 5 ​​are fixedly connected by a connecting piece 6. The connecting piece 6 is fixedly sleeved on the outer surface of the mechanism that drives the deep hole drill bit 1 to rotate. A raised ring 7 is arranged at the front end of the collecting sleeve 3, and a card interface 8 is arranged at the bottom end of the collecting sleeve 3. A collecting bottle 9 is slidably inserted inside the card interface 8.

[0035] Specifically, a baffle 10 is slidably connected to the upper surface of the collecting sleeve 3, and limiting grooves 11 are provided on both sides of the interior of the collecting sleeve 3. The interior of the limiting grooves 11 is slidably connected to limiting blocks 12. The two limiting blocks 12 are rotatably connected via a steel brush 13, and the limiting blocks 12 and the collecting sleeve 3 are connected via screws 18. Such an arrangement can ensure that the powder in the guide groove 102 can be discharged in time.

[0036] In some embodiments, a spring head 14 is vertically fixedly installed at the front end of the raised ring 7. There are multiple spring heads 14, which are distributed in a circular array. The position of the raised ring 7 can be fixed by setting the spring head 14.

[0037] In some embodiments, a plug-in port 15 is provided at the top of the collecting bottle 9, and the plug-in port 15 is slidably inserted into the interior of the card interface 8. A sealing cover 16 is slidably connected to the outer surface of the plug-in port 15, and a sealing plug 17 is threadedly connected to the bottom end of the collecting bottle 9. Such a setting can facilitate the discharge of the collected powder.

[0038] Specifically, a magnetic plate 19 is provided on one side of the sealing cover 16 and one side of the card interface 8, and a magnetic plate that attracts the magnetic plate 19 is provided on the side wall of the collecting bottle 9. Such a setting can maintain stability during the card connection process.

[0039] Specifically, the deep hole drill 1 includes an alloy head 101 at the front end and a rod body with a lead groove 102 connected to the rear end of the alloy head 101. Through such a configuration, the alloy head 101 can be used to quickly open a hole and the powder in the hole opening process can be discharged in time.

[0040] Specifically, the diameter of the through hole in the middle of the collecting sleeve 3 is equal to the diameter of the deep hole drill bit 1. Through such a setting, it can be ensured that the powder in the lead groove 102 enters the collecting sleeve 3. The diameter of the raised ring 7 is the same as the diameter of the coring drill bit 2. Through such a setting, the collecting sleeve 3 can be just clamped in the platform opened by the coring drill bit 2.

[0041] Specifically, the bottom end of the collecting sleeve 3 is tilted, and the card interface 8 is arranged on the side of the bottom end of the collecting sleeve 3 close to the raised ring 7. Through such an arrangement, the powder can fall first when entering the collecting sleeve 3, and the powder cleaned by the steel brush 13 can also be concentrated.
