Description

Technical Field

[0001] The invention relates to the technical field of rock dust collecting devices, and in particular to a rock dust collecting device used for collecting geological prospecting samples. Background Art

[0002] Geological exploration is a comprehensive geological work. It mainly focuses on investigating and studying the geological conditions such as rocks, strata, structures, minerals, groundwater, and landforms in a certain area according to the needs of economic construction, national defense construction, and scientific and technological development. There are many methods of geological exploration, including geological mapping, drilling, geophysical exploration (geophysical exploration), geochemical exploration (geochemical exploration), trench exploration, pit exploration, and sampling and testing. These methods can complement each other and be used in combination to obtain more accurate geological information. For example, drilling can directly obtain core samples of underground rock formations to study the properties, structure, and occurrence of mineral resources; while geophysical exploration and geochemical exploration use physical and chemical methods to infer the underground geological structure and distribution of mineral resources. In geological exploration, it is usually necessary to sample rock samples. The traditional geological prospecting groove method, also known as groove sampling, is a commonly used sampling method in natural outcrops or pit exploration projects. It mainly carves a long groove according to certain specifications along the thickness direction of the ore body or the direction where the mineral quality changes the most, and collects all the ore fragments chiseled from it as samples. This method is applicable to various types of solid minerals and is widely used in all stages of mineral geological work and in production mines.

[0003] In the traditional geological prospecting grooving method, when sampling by grooving, workers are required to hold a grooving machine and continuously cut along the rock wall to break the rock on the rock wall into rock chips. When the grooving machine is cutting, a large amount of flying rock powder will be generated. The existing rock powder collection method is to collect the rock powder manually after cutting. Due to the large range of rock powder splashing, manual collection is more troublesome. Therefore, the market urgently needs to develop a rock powder collection device for geological prospecting sample collection to help people solve the existing problems. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) In the present invention, the splashed rock powder generated during the cutting process of the notching machine is effectively collected and guided by arranging structures such as an arc baffle, a rock powder baffle, a material guide hood, a separation box and a collection box. The arc baffle can initially block the splashed rock powder, and the rock powder baffle can realize adaptive rotation through rollers to ensure that the rock powder can smoothly enter the rock powder inlet. The material guide hood guides the rock powder into the separation box, and the oblique blocking net blocks the rock powder so that it falls into the collection box for storage.

[0017] (2) In the present invention, by setting the rock powder baffle, the roller set at its lower end can slide along the lower end of the rock cutting position, ensuring that the rock powder baffle always remains perpendicular to the direction of rock powder splashing. At the same time, through the cooperation of the damping telescopic rod and the spring, the stability and adaptability of the rock powder baffle are further enhanced, so that it can automatically adjust the angle according to the change of the rock cutting position. This adaptive rotation design greatly improves the practicality and adaptability of the device.

[0018] (3) In the present invention, the motor and fan blades in the suction fan housing generate negative pressure, which enhances the suction effect of the rock powder inlet. This design further improves the rock powder collection efficiency and ensures that more rock powder can be collected in the collection box. At the same time, the collection box and the separation box are fixedly connected by screws. This detachable design facilitates the disassembly and replacement of the collection box and is convenient for the storage and subsequent testing of the collected rock powder.

Support rods 204 are fixedly connected on both sides of the part, and a roller 205 is rotatably connected at the lower end between the two support rods 204. The roller 205 and the two support rods 204 are rotatably connected through a second rotating shaft 206. When the notching machine 1 is notching the rock, the rock powder baffle 2 is used to block the rock powder splashed at the lower end when the saw blade of the notching machine 1 rotates. When the roller 205 slides along the lower end of the rock cutting position, the rock powder baffle 2 can be adaptively rotated through the first rotating shaft 202. When the notching machine 1 is notching, the rock powder baffle 2 can be kept perpendicular to the rock powder splashing direction, so that the splashed rock powder can enter the rock powder inlet 203.

[0028] See also Figure 3 and Figure 6A damping telescopic rod 3 is connected between the upper end of the rear end of the rock powder baffle 2 and the lower end of the front end of the arc baffle 101, the lower end of the damping telescopic rod 3 and the upper end of the rear end of the rock powder baffle 2 are rotatably connected via a first connecting shaft 301, the upper end of the damping telescopic rod 3 and the lower end of the front end of the arc baffle 101 are rotatably connected via a second connecting shaft 302, the upper end of the damping telescopic rod 3 and the lower end of the telescopic end of the damping telescopic rod 3 are fixedly connected to a limiting disc 303, a spring 304 is arranged on the outside of the damping telescopic rod 3 and between the two limiting discs 303, when the rock powder baffle 2 is adaptively rotated, the damping telescopic rod 3 is synchronously driven to be extended and retracted, and the spring 304 is made to follow the extension and retraction, and the roller 205 at the lower end of the rock powder baffle 2 is kept in contact with the rock cutting position by the restoring force of the spring 304, to prevent the rock powder baffle 2 from deflecting at will.

[0029] See also Figure 2-5 The rear end of the rock powder baffle 2 is connected to a material guide cover 4, and the rear end of the material guide cover 4 is fixedly connected to a separation box 402. A material drop opening 404 is provided on the lower end surface of the separation box 402, and a collecting box 5 is connected to the lower end of the material drop opening 404. The front end of the material guide cover 4 is connected to the rock powder inlet 203, and an oblique blocking net 403 is provided inside the separation box 402 and at the upper end of the material drop opening 404. The rear end of the material guide cover 4 is connected to the inside of the separation box 402, and the upper end of the collecting box 5 is connected to the material drop opening 404. The splashed rock powder enters the material guide cover 4 through the rock powder inlet 203, and is guided by the material guide cover 4. When it reaches the inside of the separation box 402, the flying rock powder is blocked by the oblique blocking net 403, so that the rock powder is intercepted by the oblique blocking net 403 and then falls through the drop port 404 to enter the collection box 5 for collection. The upper edge of the collection box 5 is fixedly connected with a connecting frame 501, and the upper end of the connecting frame 501 is fixedly connected to the lower end of the separation box 402 by a plurality of screws 502. After the collection is completed, the collection box 5 can be separated from the lower end of the separation box 402 by removing the plurality of screws 502, and the rock powder in the collection box 5 can be stored for subsequent detection.

[0030] See also Figure 2-5 A suction fan shell 6 is fixedly arranged in the middle of the upper end of the separation box 402, an air outlet 405 is arranged in the middle of the upper end surface of the separation box 402, a circular blocking net 406 is fixedly arranged inside the air outlet 405, the lower end of the suction fan shell 6 is connected with the inside of the air outlet 405, a motor 601 is fixedly arranged inside the suction fan shell 6, a plurality of fan blades 602 are fixedly connected to the output shaft of the motor 601, the motor 601 and the inner wall of the suction fan shell 6 are connected by a plurality of fixing rods, and the motor 601 drives the plurality of fan blades 602 to rotate to absorb the air inside the separation box 402, so that a small negative pressure is generated inside the separation box 402, so that the rock powder inlet 203 on the rock powder baffle 2 has a certain negative pressure suction effect, which is convenient for absorbing the splashed rock powder.

[0031] See also Figure 2 and Figure 4The front end of the material guide cover 4 is fixedly connected to the rock powder baffle 2 by multiple bolts 401. The material guide cover 4 and the components connected to its rear end can be separated by removing the multiple bolts 401. A rectangular blocking plate is fixedly connected to the rear end of the rock powder inlet 203 of the rock powder baffle 2 by bolts 401 to close the rock powder inlet 203. This is convenient for blocking the splashing direction of the rock powder during the use of the notching machine 1 when there is no need to collect the rock powder, so as to prevent the splashing rock powder from causing damage to the operator's legs.

[0032] Working principle: When in use, first start the motor 601 in the suction fan housing 6, and the motor 601 drives the fan blades 602 to rotate, thereby generating negative pressure inside the separation box 402. This negative pressure effect also enables the rock powder inlet 203 on the rock powder baffle 2 to have a certain suction capacity. Then, the operator holds the notching machine 1 to perform notching operations on the rock. The notching machine 1 uses the arc baffle 101 on it to initially block the splashing rock powder generated during the cutting process. The design of the arc baffle 101 enables it to effectively guide the rock powder to splash in the direction of the rock powder baffle 2. The rock powder baffle 2 is rotatably connected to the arc baffle 101 on the notching machine 1 through the first rotating connector 102 and the second rotating connector 201, allowing the rock powder baffle 2 to rotate adaptively during the notching process. The roller 205 at the lower end of the rock powder baffle 2 can slide along the lower end of the rock cutting position to ensure that the rock powder baffle 2 is always perpendicular to the rock powder splashing direction. At the same time, the stability and adaptability of the rock powder baffle 2 are further enhanced by the synergistic effect of the damping telescopic rod 3 and the spring 304, so that it can automatically adjust the angle according to the change of the rock cutting position. The collected rock powder then enters the separation box 402 through the diversion effect of the guide cover 4. The guide cover 4 is fixedly connected to the rock powder baffle 2 by multiple bolts 401, ensuring the close connection and stable transmission between the guide cover 4 and the rock powder baffle 2. Inside the separation box 402, the oblique blocking net 403 blocks the rock powder to prevent the rock powder from being sucked out with the air. The blocked rock powder falls smoothly and enters the collection box 5 through the drop opening 404 for storage. The collection box 5 is fixedly connected to the separation box 402 by a connecting frame 501 and multiple screws 502. This detachable design facilitates the disassembly and replacement of the collection box 5, and is convenient for the storage and subsequent detection of the collected rock powder. After the groove engraving operation is completed, the operator can separate the collection box 5 from the lower end of the separation box 402 by removing the screws 502. At the same time, if there is no need to collect rock powder, the operator can also separate the guide cover 4 and the parts connected to the rear end from the rock powder baffle 2 by removing the bolts 401. At this time, a rectangular blocking plate (not shown in the figure) can be fixedly connected to the rear end of the rock powder inlet 203 to effectively block the splashing rock powder and prevent it from causing harm to the operator.
