Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to a sampling and real-time quality detection device. Background Art

[0002] When grain is harvested, in order to better store the grain, it is generally necessary to test the moisture content of the grain. Generally, the grain is sampled through a grain sampling machine and then transported to a grain moisture detector for testing. The grain sampling machine is a device that samples and checks the quality of grain in a grain pile by inserting grain from each layer of the grain pile. In actual applications, electrical control has been gradually adopted, and the degree of automation has gradually increased. It is an automated electric tool for taking grain samples. The mechanical structure of the existing electric grain sampling machine mainly includes: a base fixed on the ground or the hull, a column installed on the base, a beam that can rotate around the column with the column, and a sampling tube installed on the beam that can move telescopically. The sampling tube can be inserted and raised by the telescopic movement of the sampling tube to complete the sampling of grain in each layer of the grain pile. Before sucking grain, the traditional sampling machine needs to open the grain sucker first to form a negative pressure in the sampling rod so that the sampling rod can suck the grain after it extends into the grain surface. When the sampling rod hits a hard object, it automatically stops descending, completing a point sampling, and the grain enters the grain sucker storage bin through the grain suction pipe, completing a sampling.

[0003] In order to better inspect the grain, it is necessary to sample each part of the grain truck before inspecting. However, after sampling the grain, the grain sampling machine in the prior art needs to store the grain and then manually transport it to the inspection department for inspection.

[0026] The top plate of the lifting plate 11 is provided with a first recovery box 16, and a sampling rod 15 is provided along the lower side of the front end center of the bottom of the lifting plate 11. A connecting pipe 17 extends from the front center of the first recovery box 16, and the other end of the connecting pipe 17 is connected to the top of the sampling rod 15;

[0027] A negative pressure fan 20 is arranged on the back side of the first recovery box 16, a discharge port is opened at the bottom of the first recovery box 16 and in front of the negative pressure fan 20, a first discharge pipe 21 is arranged on the outer surface of the discharge port, the other end of the first discharge pipe 21 passes through the lifting plate 11 and is located below the lifting plate 11, a second recovery box 23 is fixedly installed on the top of the top plate 5 and below the first discharge pipe 21, the top of the second recovery box 23 is connected to the bottom of the first discharge pipe 21, a discharge port is opened at the bottom center of the second discharge pipe 23, and a second discharge pipe 24 is arranged on the outer surface of the discharge port.

[0028] Furthermore, a sampling head 18 is provided at the bottom center of the sampling rod 15 , and a temperature sensor 19 is fixedly connected to the outer surface of the needle at the bottom of the sampling head 18 .

[0029] Furthermore, the inner surface of the first discharge pipe 21 is connected to the moisture sensor 22 .

[0030] Furthermore, a solenoid valve 25 is disposed on the surface of the second discharge pipe 24 .

[0031] Furthermore, a controller is provided on the front side of one of the support columns 4 , and the controller is electrically connected to the electric telescopic rod 10 , the negative pressure fan 20 , the solenoid valve 25 , the first electric guide rail 1 , and the second electric guide rail 7 .

[0032] Furthermore, the controller is electrically connected to the temperature sensor 19 and the moisture sensor 22 .

[0033] It should be noted that the electrical connection between the controller and the temperature sensor 19, the moisture sensor 22, the electric telescopic rod 10, the negative pressure fan 20, the solenoid valve 25, the first electric guide rail 1, and the second electric guide rail 7 is the prior art, and its specific connection structure and circuit diagram will not be described in detail here.

[0034] Working principle: When in use, first start the first electric guide rail 1 and the second electric guide rail 7 through the controller, so that the sampling head 18 can be moved to a suitable place, and then the electric telescopic rod 10 can be started through the controller, thereby extending and retracting the electric telescopic rod 10, so as to move the sampling head 18 to different heights, wherein the extension and retraction of the electric telescopic rod 10 is the prior art and will not be described in detail here. In addition, the first electric guide rail 1 makes the first electric slider 2 slide along the first electric guide rail 1 and the second electric guide rail 7 makes the second electric slider 8 move along the second electric guide rail 7, which is the prior art and will not be described in detail here, thereby sampling the grain in different parts of the grain truck, so as to better detect the quality of all the grain in the grain truck.

[0035] Specifically, the bottoms of the two first electric guide rails 1 are fixedly connected to the ground. Before use, the grain vehicle needs to be driven to the middle of the two first electric guide rails 1 to facilitate sampling of the grain.

[0036] After the sampling head 18 is moved to a suitable place through the above steps, the temperature sensor 19 at the bottom of the sampling head 18 displays the temperature on the display screen of the controller. When the temperature is suitable, the negative pressure fan 20 is started by the controller. After the negative pressure fan 20 is started, the grain will enter from the sampling head 18, and then pass through the sampling tube 15 and the connecting tube 17 to enter the first recovery box 16 where the negative pressure fan 20 is located, wherein the connecting part of the negative pressure fan 20 and the first recovery box 16 is provided with a vent, and a dustproof net is also provided in front of the vent. By providing the dustproof net, the dust generated by the grain during the sampling process is blocked in front of the negative pressure fan 20 to prevent the negative pressure fan 20 from being damaged by the dust sucked in.

[0037] After the grain enters the first recovery box 16, the strong wind force of the negative pressure fan 20 will also suck the grain towards the negative pressure fan 20. A discharge port is arranged in front of the negative pressure fan 20. After sampling suitable grain, the negative pressure fan 20 is closed. At this time, the grain in the discharge port will fall from the discharge port into the first discharge pipe 21. When the grain passes through the first discharge pipe 21, the moisture in the grain will be measured by the moisture sensor 22, and then the information will be displayed on the controller display screen. The grain will fall into the second recovery box 23. The staff will determine the quality of the grain according to the information on the display screen. When the quality of the grain is qualified, the staff will open the solenoid valve 25 through the controller, so that the grain in the second recovery box 23 will return to the interior of the grain truck through the second discharge pipe 24.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
