DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0021] Example 1: The present invention provides a raw material sampler with humidity, referring to Figures 1 to 9 As shown, the raw material sampler with humidity includes a sampling container 1, a connecting piece 2 and a sampling movement device 3.

[0022] A sampling cavity 11 is provided in the sampling container 1. The top side of the sampling cavity 11 is open. The top opening of the sampling container 1 is a sampling port. The sampling container 1 is connected to the sampling motion device 3 through a connecting member 2. The sampling motion device 3 provides power for the movement of the sampling container 1. The connecting member 2 is used to connect the sampling container 1 and the sampling motion device 3.

[0023] During sampling, the raw materials fall freely in the discharge chamber, the sampling motion device 3 is started, and the sampling container 1 is driven to move through the connecting piece 2 and inserted into the discharge chamber. The sampling motion device 3 drives the sampling container 1 to move along a fixed trajectory in the discharge chamber. During the movement, part of the falling raw materials enters the sampling chamber 11 through the sampling port, completing the sampling.

[0024] In the above sampling process, the sampling container 1 is a quantitative container, and it completes sampling in a motion sampling manner along a fixed trajectory. Compared with the existing static sampling method, it can effectively improve the representativeness and stability of the sampling, and the sampling effect is significant.

[0025] Example 2: like Figures 1 to 9 As shown, the sampling motion device 3 can drive the sampling container 1 to move horizontally in the material discharge chamber through the connecting piece 2. The raw material falls naturally vertically, and the moving direction of the sampling container 1 is perpendicular to the falling direction of the raw material.

[0026] The sampling container 1 is configured as a long cubic container with an open top. The horizontal movement direction of the sampling container 1 in the discharge chamber is perpendicular to the length direction of the sampling container 1. Since the length of the sampling container 1 is greater than its width, the aforementioned mobile sampling method can effectively improve the sampling efficiency while ensuring the representativeness and stability of the sampling.

[0027] As an optional embodiment, the sampling container 1 includes two oppositely arranged side walls, two oppositely arranged end walls and a bottom wall located at the bottom. The two side walls are two side cavity walls 13 of the sampling cavity 11. The two side cavity walls 13 are arranged at an angle. Specifically, the side cavity walls 13 are offset in a direction away from their center line from top to bottom. In this way, the diameter of the sampling container 1 gradually increases in width from top to bottom.

[0028] The inclined side cavity wall 13 has a limiting function. When the raw material falls into the sampling cavity 11, the side cavity wall 13 limits the raw material in a manner of preventing the raw material from splashing, thereby further improving the sampling effect.

[0029] Preferably, the two side cavity walls 13 are symmetrically arranged, and the longitudinal cross-section of the sampling cavity 11 is an isosceles trapezoid.

[0030] As an optional embodiment, a first connecting portion is provided at the bottom of the sampling container 1, and a second connecting portion is provided on the connecting piece 2 at a position corresponding to the first connecting portion. The first connecting portion and the second connecting portion are used to connect the sampling container 1 and the connecting piece 2.

[0031] Specifically, the first connection portion is set as a first connection hole 14, and the second connection portion is set as a second connection hole 212. During installation, threaded fasteners are used to pass through the first connection hole 14 and the second connection hole 212 to connect the sampling container 1 to the connector 2.

[0032] This arrangement is not only convenient for assembly and disassembly, but also has a firm connection.

[0033] To further improve the stability of the connection, the number of the first connection holes 14 and the second connection holes 212 are both set to be multiple.

[0034] As an optional embodiment, the sampling container 1 is made of stainless steel.

[0035] As an optional embodiment, the raw material sampler with humidity includes a vibration device 4 , which is connected to the sampling container 1 .

[0036] When the sampling is completed and the sample material is transferred, the vibration device 4 is started to drive the sampling container 1 to vibrate, thereby effectively preventing the raw material from adhering to the cavity wall during the sampling process.

[0037] As an optional embodiment, a mounting cavity 211 is provided in the connector 2 at a position corresponding to the sampling container 1 , and the vibration device 4 is disposed in the mounting cavity 211 and connected to the bottom wall of the sampling container 1 .

[0038] Specifically, a mounting port is provided on the connecting member 2 at a position corresponding to the vibration device 4, and the mounting port is communicated with the mounting cavity 211. A first mounting hole 15 is provided on the bottom wall of the sampling container 1, and a second mounting hole 213 is provided on the connecting member 2 at a position corresponding to the first mounting hole 15. The threaded fastener passes through the first mounting hole 15 and the second mounting hole 213 in sequence and is connected to the vibration device 4.

[0039] Such arrangement facilitates the disassembly and assembly operations on the one hand, and facilitates the later maintenance of the vibration device 4 on the other hand.

[0040] The vibration device 4 adopts a pneumatic vibrator.

[0041] As an optional embodiment, the connecting member 2 is provided with a square connecting rod 21, which is a hollow square rod. The first end of the square connecting rod 21 is connected to the sampling movement device 3, and the second connecting hole 212, the second mounting hole 213 and the mounting port are arranged at a position close to the second end of the square connecting rod 21. In this way, the sampling container 1 is arranged on the top side of the second end of the square connecting rod 21.

[0042] Furthermore, a clearance hole 214 is provided on the bottom wall of the square connecting rod 21 at a position corresponding to the second mounting hole 213 , and the clearance hole 214 facilitates the disassembly and assembly of the corresponding threaded fastener.

[0043] As an optional embodiment, the first end of the square connecting rod 21 is provided with a flange 22, and the first end of the square connecting rod 21 is flange-connected to the sampling motion device 3 through the flange 22. The flange connection method is easy to install, and the connection structure is firm and reliable, providing a basis for the smooth subsequent sampling and sample transfer.

[0044] A plurality of reinforcing ribs 23 are provided on the flange 22 along the circumferential direction. The reinforcing ribs 23 are connected to the square connecting rods 21 . The provision of the reinforcing ribs 23 further improves the structural firmness.

[0045] As an optional embodiment, the sampling motion device 3 is configured as a multi-axis robot 31 .

[0046] The multi-axis robot 31 is a six-axis robot, including a basic axis for realizing the position movement and positioning of the terminal sampling container 1 in three-dimensional space and a wrist axis for controlling the spatial posture of the terminal sampling container 1 .

[0047] Specifically, it includes the base rotation axis, the lower arm forward and backward swing axis, the upper arm lifting axis, the wrist rotation axis, the wrist pitch axis and the end flange rotation axis.

[0048] Example 3 Example 3 is based on Example 2: The present invention provides a sampling method using the raw material sampler with humidity, and the sampling method at least comprises the following steps: Step I: the sampling motion device 3 drives the sampling container 1 to move and insert it into the feeding cavity through the sampling port; Step II: The sampling motion device 3 drives the sampling container 1 to move along a fixed track in the material discharge chamber. During the movement, the raw materials falling from the material discharge chamber fall into the sampling chamber 11 through the opening 12 at the top of the sampling container 1; The fixed track is a horizontal uniform movement perpendicular to the length direction of the sampling container 1 .

[0049] In step III, the sampling motion device 3 drives the sampling container 1 to move and move it out of the feeding cavity through the sampling port, and the sampling is completed.

[0050] The sampling method of the present invention adopts a fixed trajectory combined with dynamic sampling to achieve sampling, which can effectively ensure the representativeness and stability of the sampling.
