[0032] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0033] Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, refer to Figures 1 to 3 , which is the first embodiment of the present invention. This embodiment provides a positioning mechanism that can buffer the sample box 301, so that the sample box 301 can stably fall into the groove on the surface of the rotating plate 204. It includes,

[0036] The guiding assembly 100 includes a support frame 101, a rotating plate 102 arranged on the surface of the support frame 101, a moving plate 106 movably connected to the rotating plate 102, a spring 103 connected to the surface of the moving plate 106, and a guiding plate 104 arranged on the surface of the moving plate 106; wherein,

[0037] When the guiding plate 104 is collided, the moving plate 106 moves relative to the rotating plate 102 following the guiding plate 104, and the spring 103 is compressed.

[0038] The rotating plate 102 is rotatably connected to the support frame 101, and the other end of the spring 103 is fixedly connected to the support frame 101. The rotating plate 102 can rotate, which is convenient for the guiding plate 104 to change its position.

[0039] The spring 103 is inclined with the moving plate 106. The inclined setting can simultaneously rebound the backward movement of the moving plate 106 and the rotation of the moving plate 106 following the rotating plate 102.

[0040] An extension rod is arranged on the surface of the rotating plate 102, and the moving plate 106 is slidably connected to the extension rod. The moving direction of the moving plate 106 is fixed to ensure the stable connection between the moving plate 106 and the rotating plate 102.

[0041] When the guiding plate 104 is collided, the moving plate 106 moves following the guiding plate 104, then the spring 103 is squeezed. When the guiding plate 104 is pushed laterally, the rotating plate 102 rotates relative to the support frame 101, and the spring 103 is squeezed. The positioning plate 105 is fixed on the surface of the support frame 101 through the connecting plate 107, and the positioning plate 105 does not move when it is collided.

[0042] Example 2, refer to Figures 1 to 9 , which is the first embodiment of the present invention. This embodiment provides a bottom-opening collector that can automatically add coal samples in multiple batches to the feed inlet of the sample preparation machine. It includes,

[0043] The rotating assembly 200 includes a bottom plate 201, a support cylinder 209 connected to the bottom of the bottom plate 201, a motor 207 arranged inside the support cylinder 209, a rotating plate 204 drivingly connected to the motor 207, a connecting groove 211 arranged on the surface of the bottom plate 201, a discharge pipe 202 arranged directly below the connecting groove 211, and an electromagnet 210 connected inside the discharge pipe 202; and,

[0044] The sample storage assembly 300 includes a sample box 301, a connecting frame 306 connected inside the sample box 301, a guiding column 305 connected to the bottom of the connecting frame 306, a sealing plate 304 sliding on the surface of the guiding column 305, and a magnetic plate 309 connected to the bottom of the sealing plate 304. Among them,

[0045] When the rotating plate 204 drives the sample box 301 to move directly above the connecting groove 211, the electromagnet 210 pushes the magnetic plate 309 upward through magnetic force, and the coal sample in the sample box 301 enters the discharge pipe 202.

[0046] The surface of the rotating plate 204 is provided with a groove, and a through groove 205 is provided in the middle of the groove.

[0047] The groove can hold the sample box 301 to ensure that the sample box 301 can move stably.

[0048] The size of the through groove 205 is the same as that of the connecting groove 211, and the position of the through groove 205 is correspondingly set with the sealing plate 304.

[0049] It is convenient for the coal sample inside the sample box 301 to flow out completely, reducing the remaining coal sample.

[0050] The sample storage assembly 300 is conveyed by the conveyor belt to the position of the feeding port 206. The bottom of the sample box 301 is stuck in the groove on the surface of the rotating plate 204. The motor 207 drives the rotating plate 204 to rotate, and the rotating rotating plate 204 drives the sample storage assembly 300 to move. When the sample box 301 moves to the position of the discharging port 203, the sealing plate 304 is aligned with the connecting groove 211. Since the through groove 205 is provided on the surface of the rotating plate 204, there is no obstruction between the discharge pipe 202 and the sealing plate 304 at this time. The electromagnet 210 is energized to generate magnetic force. Since the magnetic force of the magnetic plate 309 repels the electromagnet 210, the magnetic plate 309 receives an upward force, the sealing plate 304 moves upward, and the sealing plate 304 moves upward along the guiding column 305. Then the coal sample inside the sample box 301 flows out from the discharging circle 308 along the sliding plate 303.

[0051] Example 3, refer to Figures 1 to 9 , which is the third example of the present invention. Different from the previous example, this example provides a feeding channel for the bottom-opening collector, which solves the problem of rapid discharge of pulverized coal inside the sample box 301, including,

[0052] A weighing frame 302 is fixed to the bottom of the sample box 301, and a discharging circle 308 is provided in the middle of the weighing frame 302.

[0053] The weighing frame 302 can weigh the coal sample to obtain the weight of the coal sample.

[0054] The upper end of the discharging circle 308 is fixedly connected to the sample box 301, and the sealing plate 304 is slidably connected to the discharging circle 308.

[0055] Fix the moving direction of the fixed sealing plate 304 to ensure the stable opening of the sealing plate 304.

[0056] A locking plate 307 is rotatably connected to the upper end of the sample box 301, and a sealing lock is arranged on the surface of the locking plate 307.

[0057] The sealing lock on the surface of the locking plate 307 can prevent subsequent personnel from opening it and avoid the replacement of internal samples.

[0058] The coal sample is introduced into the sample box 301 through the locking plate 307 at the top to complete the sealing of the coal sample. The weight sensor inside the measuring frame 302 weighs the coal sample to obtain the mass of the coal sample.

[0059] Working principle: The sample storage assembly 300 is filled with coal samples in the sampling machine and is transported to the feeding port 206 position through the conveyor belt. There is inertia on the surface of the sample storage assembly 300, which squeezes the guiding plate 104. The moving plate 106 moves along with the guiding plate 104, and the spring 103 is squeezed. Then the bottom of the sample box 301 is stably stuck in the groove on the surface of the rotating plate 204. The motor 207 drives the rotating plate 204 to rotate. The rotating rotating plate 204 drives the sample storage assembly 300 to move. When the guiding plate 104 is horizontally pushed by the sample box 301, the rotating plate 102 rotates relative to the support frame 101, and the spring 103 is squeezed. Then the sample box 301 passes through the guiding plate 104. When the sample box 301 moves to the position of the discharging port 203, the sealing plate 304 is aligned with the connecting groove 211. Since the through groove 205 is arranged on the surface of the rotating plate 204, there is no obstruction between the discharging pipe 202 and the sealing plate 304 at this time. The electromagnet 210 is energized to generate magnetic force. Since the magnetic plate 309 repels the magnetic force of the electromagnet 210, the magnetic plate 309 receives an upward force, and the sealing plate 304 moves upward. The sealing plate 304 moves upward along the guiding column 305, and the coal sample inside the sample box 301 flows out from the discharging circle 308 along the sliding plate 303 and enters the feeding port of the sample preparation machine through the discharging pipe 202 for sample preparation. The rotating plate 204 continues to rotate. Since the positioning plate 105 is fixed on the surface of the support frame 101 through the connecting plate 107 and does not move when being collided, the sample box 301 is squeezed to separate from the rotating plate 204, thus completing the transportation of multiple batches of coal samples.
