Description

Technical Field

[0001] This utility model relates to the field of coal counting instruments, specifically a portable, quick-release millimeter-wave radar coal counting instrument. Background Technology

[0002] A coal counting device is a device used to measure the volume and weight of material piles (such as coal piles, earthworks, ores, etc.). Portable coal counting devices can be operated by a single person and are suitable for situations where there are no stacker-reclaimers or bucket wheel excavators. However, traditional radar coal counting devices are relatively inconvenient to disassemble, making the process of carrying and disassembling them more complicated and affecting the overall convenience of using the radar coal counting device.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent Publication No. CN222704145U, Publication Date 2025-04-01) provides a fixed coal panning device installed on the top of a coal shed. This device includes a horizontal frame and an extension plate. The extension plate is located at the side end of the horizontal frame. A dust-removing shield is mounted on the extension plate and the horizontal frame. The main body of the coal panning device is located at the bottom of the horizontal frame. A retraction assembly is located between the horizontal frame and the main body of the coal panning device. Telescopic rods are all installed inside the side end face of the horizontal frame. The output end of the telescopic rod is connected to the extension plate. A reinforcing connecting rod is provided on the side end face of the extension plate, and one end of the reinforcing connecting rod is connected to the movable sleeve of the horizontal frame. This technical solution solves the problems of existing fixed coal panning devices installed on the top of coal sheds, where the large amount of coal dust inside the shed easily falls and adheres to the surface of the coal panning device. When dust falls on the probe surface, it easily affects the normal operation of the coal panning device. Furthermore, because the coal panning device is installed on the top of the coal shed, cleaning it is difficult and inefficient.

[0004] The aforementioned institutions utilize coal counting instruments installed on the top of coal sheds; however, the fixed connection of the coal counting instruments reduces their ease of use and affects their flexibility. Utility Model Content

[0005] The purpose of this utility model is to provide a portable, quick-disassembly millimeter-wave radar coal counting instrument to solve the problem mentioned in the background art that traditional radar coal counting instruments are inconvenient to disassemble during use, resulting in a complicated process during carrying and disassembly, which affects the overall convenience of using the radar coal counting instrument.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable, quick-release millimeter-wave radar coal counting instrument, comprising a radar coal counting instrument body, a fixed base plate installed at the bottom of the radar coal counting instrument body, a storage box sleeved on the outer side of the radar coal counting instrument body, and a top protective cover snapped onto the top of the storage box; an mounting plate is attached to the bottom of the fixed base plate, and disassembly and assembly mechanisms for disassembling the radar coal counting instrument body are provided at both the front and rear ends of the mounting plate, the disassembly and assembly mechanisms including limiting blocks, the limiting blocks being fixedly connected to the middle position of the front and rear ends of the fixed base plate, and limiting rings being rotatably connected to both the front and rear ends of the mounting plate, the limiting rings being snapped onto the outside of the limiting blocks; a drive motor is installed at the bottom of the storage box, and the output end of the drive motor extends into the interior of the storage box and is equipped with a height adjustment mechanism for adjusting the position of the radar coal counting instrument body.

[0007] Furthermore, a torsion spring is fixedly connected to the front end of the limiting ring, and the limiting ring forms an elastic structure with the mounting plate through the torsion spring.

[0008] Furthermore, the cross-section of the limiting ring is inverted "J" shape, and the inner diameter of the upper end of the limiting ring is larger than the diameter of the limiting block.

[0009] Furthermore, the height adjustment mechanism includes a threaded rod, which is connected to the output end of the drive motor via a sprocket transmission mechanism. A movable block is threadedly connected to the outer side of the threaded rod, and the movable block is fixedly connected to the left and right sides of the mounting plate.

[0010] Furthermore, slide rails are provided on both the left and right sides inside the radar coal counting instrument body, and sliders matching the slide rails are installed on the sides of the movable block. The movable block and the radar coal counting instrument body are connected by the sliding sliders and slide rails to form a sliding mechanism.

[0011] Furthermore, an elastic airbag is installed at the bottom of the radar coal counting instrument body, and a propulsion plate is attached to the top of the elastic airbag. Protective airbags are fitted on the upper and lower ends of the outer side of the storage box. The elastic airbag is connected to the protective airbag through a hose, and the protective airbags are connected to each other through a hose.

[0012] Furthermore, reset springs are provided at both the front and rear ends of the bottom of the push plate, and the push plate and the storage box form an elastic structure through the reset springs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By aligning the fixed base plate and the mounting plate, and matching the position of the limiting block with the position of the torsion spring, the angle of the limiting ring is adjusted so that the limiting ring can be engaged with the limiting block, thereby achieving the docking and installation between the fixed base plate and the mounting plate, and enabling the rapid assembly and disassembly of the radar coal meter body.

[0015] Furthermore, the limiting ring is connected to the mounting plate via a torsion spring. The torsion spring allows the limiting ring to quickly and automatically reset after being adjusted in angle, thus making the engagement between the limiting block and the limiting ring more stable, reducing the shaking of the radar coal meter body, and increasing stability during use.

[0016] Furthermore, the cross-section of the limiting ring is inverted J-shaped. The shape of the upper end of the limiting ring can better fit and limit the outer side of the limiting block, effectively reducing the positional offset between the fixed base plate and the mounting plate.

[0017] 2. The output of the drive motor rotates, which in turn drives the threaded rod to rotate. The threaded rod and the movable block are connected by a thread, so that when the threaded rod rotates, the movable block moves up and down. When the movable block moves, it drives the mounting plate to change its height, which in turn allows the mounting plate to adjust the height of the radar coal meter body, thus enabling the radar coal meter body to be stored. The storage box and the top protective cover can protect the radar coal meter body and reduce the possibility of the radar coal meter body being hit by collisions inside.

[0018] Furthermore, when the mounting plate is moved downwards, it pushes the propulsion plate, which in turn compresses the elastic airbag. The gas inside the elastic airbag is delivered to the interior of the protective airbag through a hose. The protective airbag is fitted onto the upper and lower ends of the storage box. The protective airbag acts as a buffer when the storage box is involved in a collision, preventing the corners at the top and bottom of the storage box from being directly impacted and damaged.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution presented addresses the problem that traditional radar coal counting instruments are inconvenient to disassemble, leading to complex handling and reduced usability. This portable, quick-release millimeter-wave radar coal counting instrument discloses a quick-release mechanism, including a radar coal counting instrument body 1. A fixed base plate 4 is mounted on the bottom of the radar coal counting instrument body 1. A storage box 2 is fitted around the outside of the radar coal counting instrument body 1, and a top protective cover 3 is snapped onto the top of the storage box 2. A mounting plate 5 is attached to the bottom of the fixed base plate 4, and the mounting plate 5... Both ends of the device are equipped with disassembly and assembly mechanisms for disassembling the radar coal detector body 1. The disassembly and assembly mechanisms include limiting blocks 6, which are fixedly connected to the middle position of the front and rear ends of the fixed base plate 4. Both ends of the mounting plate 5 are rotatably connected to limiting rings 7, which are engaged with the outside of the limiting blocks 6. A torsion spring 8 is fixedly connected to the front end of the limiting ring 7, and the limiting ring 7 forms an elastic structure with the mounting plate 5 through the torsion spring 8. The cross-section of the limiting ring 7 is inverted "J" shape, and the inner diameter of the upper end of the limiting ring 7 is larger than the diameter of the limiting block 6.

[0028] In this example, the radar coal inventory unit 1 is placed on a support. The radar coal inventory unit 1 can measure the volume of the coal pile. When not in use or requiring maintenance, the radar coal inventory unit 1 can be quickly disassembled and assembled using a quick-release mechanism, making its overall use more convenient. By aligning the fixed base plate 4 and the mounting plate 5, and aligning the position of the limiting block 6 with the position of the torsion spring 8, the angle of the limiting ring 7 is adjusted so that the limiting ring 7 can maintain a engaged state with the limiting block 6, thereby achieving the docking and installation of the fixed base plate 4 and the mounting plate 5. The radar coal meter body 1 can be quickly disassembled and assembled, increasing the overall flexibility during use. The limiting ring 7 is connected to the mounting plate 5 through a torsion spring 8. The torsion spring 8 allows the limiting ring 7 to quickly and automatically reset after being adjusted by the elastic force, thereby making the engagement between the limiting block 6 and the limiting ring 7 more stable, reducing the shaking of the radar coal meter body 1 and increasing the stability during use. The cross-section of the limiting ring 7 is inverted J-shaped. The shape of the upper end of the limiting ring 7 can better fit and limit the outer side of the limiting block 6, effectively reducing the positional offset between the fixed base plate 4 and the mounting plate 5.

[0029] Example 2: Figure 1 , Figure 3 , Figure 4 and Figure 5 The technical solution shown addresses the problem of radar coal reconnaissance instruments being inconvenient to quickly store inside a housing for safe carrying during use. This portable, quick-release millimeter-wave radar coal reconnaissance instrument discloses a height adjustment mechanism. A drive motor 9 is installed at the bottom of the storage box 2, and the output end of the drive motor 9 extends into the storage box 2 and is equipped with a height adjustment mechanism for adjusting the position of the radar coal reconnaissance instrument body 1. The height adjustment mechanism includes a threaded rod 10, which is connected to the output end of the drive motor 9 via a sprocket transmission mechanism. A movable block 11 is threadedly connected to the outer side of the threaded rod 10, and the movable block 11 is fixedly connected to the left and right sides of the mounting plate 5. Slide rails 13 are provided on both the left and right sides inside the radar coal reconnaissance instrument body 1, and sliders 12 matching the slide rails 13 are installed on the sides of the movable blocks 11. The movable blocks 11 and the radar coal reconnaissance instrument body 1 are connected by sliding sliders 12 and slide rails 13 to form a sliding mechanism.

[0030] In this example, when not in use, the radar coal detector body 1 can be moved and stored inside the storage box 2. The storage box 2 protects the radar coal detector body 1 and completely encloses it, making it easier to carry. The output of the drive motor 9 rotates, causing the threaded rod 10 to rotate. The threaded rod 10 is threadedly connected to the movable block 11, so that the rotation of the threaded rod 10 causes the movable block 11 to move up and down. This movement of the movable block 11 changes the height of the mounting plate 5, allowing the mounting plate 5 to... The height of the radar coal meter body 1 can be adjusted to allow for its storage. The storage box 2 and the top protective cover 3 protect the radar coal meter body 1, reducing the possibility of it being hit internally. During the movement of the movable block 11, the cooperation of the slider 12 and the slide rail 13 ensures smoother movement. When the threaded rod 10 rotates to adjust the height of the movable block 11, the slider 12 and the slide rail 13 limit the movement, preventing the angle of the movable block 11 from deflecting, thus allowing the mounting plate 5 to move more flexibly.

[0031] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 5 The technical solution shown addresses the issue of insufficient protection for the radar coal detector body 1 during portability. This portable, quick-release millimeter-wave radar coal detector discloses a protective mechanism. An elastic airbag 15 is installed at the bottom of the radar coal detector body 1, and a push plate 14 is attached to the top of the elastic airbag 15. Protective airbags 17 are fitted onto the upper and lower ends of the outer side of the storage box 2. The elastic airbag 15 is connected to the protective airbag 17 via a flexible hose, and the protective airbags 17 are connected to each other via flexible hoses. Return springs 16 are installed at both the front and rear ends of the bottom of the push plate 14, and the push plate 14 and the storage box 2 form an elastic structure through the return springs 16.

[0032] In this example, when the mounting plate 5 is moved downwards, it pushes the push plate 14, which in turn compresses the elastic airbag 15. The gas inside the elastic airbag 15 is delivered to the interior of the protective airbag 17 through a hose. The protective airbag 17 is fitted onto the upper and lower ends of the storage box 2. The protective airbag 17 acts as a buffer when the storage box 2 is involved in a collision, preventing direct impact to the corners at the top and bottom of the storage box 2 and thus avoiding damage to the storage box 2 itself. The reset springs 16 at the front and rear ends of the bottom of the push plate 14 assist the push plate 14 in repositioning. When the mounting plate 5 is moved to reset, the push plate 14 resets synchronously through the elastic force of the reset springs 16, allowing the elastic airbag 15 to draw the gas out of the protective airbag 17 through the hose. This allows the protective airbag 17 to be inflated again when not in use to protect the storage box 2.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
