[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-5 As shown, an unattended fully automatic multi-tube grain sampling machine comprises a main support 1 and a control host, wherein a plurality of support rods 2 are fixedly connected to the lower side of the main support 1, so that the main support 1 is located in mid-air, and a vehicle transporting grain can move to the lower side of the main support 1;

[0023] A horizontal moving mechanism is installed inside the main bracket 1, and multiple grain sampling mechanisms 7 are installed on the horizontal moving mechanism. The grain sampling mechanism 7 and the horizontal moving mechanism are electrically connected to the control host. At this time, when the vehicle is located at the lower side of the main bracket 1, the control host starts the horizontal moving mechanism to drive the multiple grain sampling mechanisms 7 to move randomly, adjust the position of the grain sampling mechanism 7, and then start the grain sampling mechanism 7 to sample the grain inside the vehicle, thereby completing multi-point random sampling of the grain and improving the efficiency and randomness of the sampling.

[0024] Among them, Figure 1-2 As shown, the horizontal moving mechanism includes an X-axis rail 3 fixedly connected to the inner walls on both sides of the main support 1, and multiple X-axis moving trolleys 4 are installed on the two X-axis rails 3. The X-axis moving trolleys 4 are electrically connected to the control host, and can drive the X-axis moving trolleys 4 to move on the X-axis rail 3 according to the control of the control host. The X-axis moving trolleys 4 on the two X-axis rails 3 are one group relative to each other, and the same group of X-axis moving trolleys 4 is installed with a Y-axis rail 5. When the X-axis moving trolley 4 moves, the position of the Y-axis rail 5 is adjusted. A Y-axis moving trolley 6 is installed on the Y-axis rail 5, and the Y-axis moving trolley 6 is electrically connected to the control host. When the Y-axis moving trolley 6 is started, it moves on the Y-axis rail 5. The grain sampling mechanism 7 is installed on the Y-axis moving trolley 6, and the movement of the Y-axis moving trolley 6 can drive the grain sampling mechanism 7 to move together, so that the positions of multiple grain sampling mechanisms 7 can be freely controlled, thereby achieving the purpose of random sampling.

[0025] like Figure 2-3 and Figure 5 As shown, the grain sampling mechanism 7 includes two vertical brackets 8 fixedly connected to the Y-axis moving trolley 6, and two vertically arranged rotating wheels 9 are rotatably connected between the two vertical brackets 8. Belts 11 are installed on the outer sides of the two rotating wheels 9. When the rotating wheels 9 rotate, the belts 11 will be driven to move on the outer sides of the two rotating wheels 9. A servo motor 10 is fixedly connected to the outer side of the vertical bracket 8, and the output end of the servo motor 10 is fixedly connected to one of the rotating wheels 9. At this time, the rotating wheels can be driven by starting the servo motor 10. 9 is rotated to achieve the purpose of transmission. The outer side of the belt 11 is fixedly connected with a connecting seat 12, and a sampling tube 13 is fixedly connected to the connecting seat 12. The upper end of the sampling tube 13 is connected with a suction pipe 14, and the suction pipe 14 is connected with a suction mechanism. A grain inlet 19 is opened at the lower end of the sampling tube 13. When the suction pipe 14 is started, a negative pressure can be generated inside the sampling tube 13, and the grain can be sucked into the inside of the grain inlet 19 by the negative pressure, and output through the grain inlet 19 and the suction pipe 14.

[0026] Moreover, a guide frame 15 is fixedly connected to the lower part between the two vertical brackets 8 and located at the lower side of the connecting seat 12, and the sampling tube 13 is slidably connected to the inside of the guide frame 15, so that the sampling tube 13 can be positioned at two points in cooperation with the connecting seat 12 to improve its stability.

[0027] like Figure 3-5 As shown, one structure of the sampling tube 13 is disclosed herein, and the sampling tube 13 includes an inner tube 16 installed on the connecting seat 12 and an outer tube 17 installed on the outside of the inner tube 16, the upper end of the inner tube 16 is connected with the suction pipe 14, and the grain inlet 19 is opened at the lower part of the inner tube 16. At this time, the adsorption of the grain by negative pressure is completed through the inner tube 16, and an air duct is formed between the inner tube 16 and the outer tube 17 to complete the circulation of air, so that when the negative pressure adsorption is performed on the inside of the vehicle grain, air can be taken into the inside of the vehicle grain.

[0028] Among them, Figure 3-5 As shown, the lower side of the inner tube 16 is fixedly connected with an end portion 18, and the end portion 18 is a conical structure. The outer tube 17 is slidably connected to the outer side of the inner tube 16, and an electric push rod 20 is installed on the upper part of the outer side of the inner tube 16. The output end of the electric push rod 20 is fixedly connected to the outer tube 17. At this time, when the sampling tube 13 enters the interior of the grain, the electric push rod 20 is started to control the lower end of the outer tube 17 and the end portion 18 to abut against each other, and the lower opening of the air duct and the grain inlet 19 are blocked. When the sampling tube 13 enters the interior of the grain, the grain will not enter the interior of the air duct and the grain inlet 19.

[0029] The working principle of the utility model is as follows: when the vehicle is located at the lower side of the main support 1, the horizontal moving mechanism is started by controlling the main engine to drive multiple grain sampling mechanisms 7 to move randomly, and the positions of the grain sampling mechanisms 7 are adjusted. After the position adjustment of the grain sampling mechanisms 7 is completed, the servo motor 10 is started to drive the belt 11 to move. When the belt 11 moves, it will drive the sampling tube 13 to enter the interior of the grain to complete the sampling of the grain.

[0030] The above is only a preferred implementation of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
