Description
Technical Field
[0001] The present invention relates to the technical field related to sampling devices, and in particular provides a sampling device for grains. Background Art
[0002] A large amount of grain is stored in the granary. In order to ensure the storage quality of the grain, it is necessary to regularly sample and test the grain in the granary to understand and monitor the quality of the grain, such as checking the moisture of the grain, whether it is moldy, whether it has sprouted, and whether it has insects.
[0003] Grain sampling devices include intubation samplers, automatic suction samplers and pre-buried tube samplers. The intubation sampler inserts a tube into the grain pile, allowing the grain to enter the tube and be taken out with the tube. The suction sampler inserts a tube into the grain and then takes out the grain by suction. Since the grain is too full in the grain warehouse, the tube is difficult to insert when it is inserted deep into the grain warehouse due to the squeezing of the grain. It is also difficult to pull it out later. In addition, the grain sucked up will also affect the later sampling due to impurities. Therefore, we need to improve the above problems. Summary of the invention

The sampled grain sample can accurately represent the actual storage status of the grain at the corresponding position and corresponding depth inside the grain depot.

[0026] The spiral sampling mechanism includes a swivel 35 rotatably installed on the lower inner side of the suction cylinder 37, a sampling rod 10 is fixedly installed on the lower inner side of the swivel 35, a sampling spiral sheet 11 is arranged on the lower outer side of the sampling rod 10, a feeding pipe 12 is cross-arranged at the upper and lower ends of the inner side of the sampling rod 10, a suction piece is arranged on the inner side of the sampling rod 10, a transmission assembly is arranged on the upper outer side of the sampling rod 10, the suction piece includes a suction pipe 22 placed on the inner side of the sampling rod 10, a connecting pipe 36 is installed on the upper inner side of the suction pipe 22, one end of the connecting pipe 36 away from the suction pipe 22 is connected to the grain sucking machine 16, and the other end of the grain sucking machine 16 is connected to the inside of the sampling cylinder 3 through a discharge pipe 13 installed in a connecting manner.
[0027] Please refer to the instruction manual Figure 3The rotating ring 35 can stably set the sampling rod 10 under the suction cylinder 37 for rotation, so that under the drive of the transmission component, the sampling rod 10 can easily allow the feeding tube 12 to be buried in the grain through the outer sampling spiral sheet 11, and then automatically transport the grain to the sampling rod 10 for storage. The suction pipe 22 is connected with the connecting pipe 36 and the grain suction machine 16 to suck the stored grain into the sampling cylinder 3 through negative pressure adsorption.
[0028] The transmission assembly includes a rotating sleeve 9 fixedly mounted on the outside of the sampling rod 10, and a No. 1 motor 5 is connected to the outside of the suction cylinder 37 through a fixedly connected bracket 6.

[0029] Please refer to the instruction manual Figure 1 , Figure 2 , Figure 3 , Figure 4 Under the connection of the bracket 6, the No. 1 motor 5 is installed on the outside of the suction cylinder 37 for stable use. After connecting the power supply, the drive shaft 8 rotates, and the rotating sleeve 9 can be rotated through the transmission of the No. 1 pulley assembly 7.

Under the connection of the No. 2 pulley assembly 15, the connecting shaft 18 below the synchronous transmission rotates. The area on the surface of the discharge cylinder 17 located inside the sampling cylinder 3 is open. The separated sample can be automatically discharged from the outer spiral conveying sheet 34 from the sealing cover 33 through the rotation of the connecting shaft 18. The sealing cover 33 is a sealing cover, which is sealed at the discharge port of the discharge cylinder 17 by a spiral connection.
[0032] The impurity removal mechanism includes an ash retaining plate 32 fixedly mounted on the outside of one end of the cylinder 26, with multiple groups of filter holes 31 provided inside the ash retaining plate 32, and a suction fan 23 is connected and installed on the side of the ash retaining plate 32 away from the cylinder 26, and a positioning component is arranged outside the suction fan 23.
[0033] Please refer to the instruction manual Figure 5The purpose of the filter holes 31 opened inside the two sets of dust shielding plates 32 is to allow the suction fan 23 to vacuum the separated grains. The suction force of the suction fan 23 can be adjusted by an externally connected controller. This is a prior art, so the function will not be described in detail.
[0034] The positioning assembly includes a sleeve 29 , and blocks 21 are installed at equal distances along the annular direction on the outside of the sleeve 29 . Rubber blocks 30 are fixedly installed on the inner walls of multiple blocks 21 . The surface of the rubber blocks 30 abuts against the outside of the suction fan 23 . The sleeve 29 is sleeved on the outside of the clamping shaft 28 .
[0035] Please refer to the instruction manual Figure 5 The sleeve 29 facilitates synchronous connection of multiple groups of card blocks 21 on the outside, so that the other end thereof can be buckled with the suction fan 23 through the provided rubber block 30, thereby cooperating with the card shaft 28 to rotate stably. The rubber block 30 can enhance the clamping effect of the card block 21 and the suction fan 23, and enhance the stability of the card installation.
[0036] Multiple groups of connecting seats 27 are installed on the outer walls of the two groups of dust shielding plates 32 on the sides close to each other. The multiple groups of connecting seats 27 are rotatably connected through corresponding movable rods 24, and a paddle 25 is inserted in the middle of the inner side of the movable rod 24.
[0037] Please refer to the instruction manual Figure 5 The two groups of ash retaining plates 32, driven by the clamping shaft 28, can block the grain at the front end of the suction fan 23. The purpose is to avoid clogging the filter hole 31 when the suction fan 23 is working to absorb ash. In addition, the multiple groups of paddles 25 arranged on the inner side of the ash retaining plate 32 can not only rotate by themselves to disperse the grain, but also flexibly disturb the air flow pressure inside the filter hole 31 through the rotating paddles 25, so as to ensure that the sampled grain does not have too many impurities.
[0038] Working principle: When in use, the No. 1 motor 5 is connected to the power supply and drives the No. 1 pulley assembly 7 at the output end to rotate. Driven by the No. 1 pulley assembly 7, the swivel 35 can drive the sampling rod 10 to drill into the grain under the suction tube 37. The sampling spiral sheet 11 at the lower outer side of the sampling rod 10 can automatically shuttle inside the grain. The grain is stored in the sampling rod 10 through the cross-connected material pipe 12 at the upper and lower ends. The grain suction machine 16 can suck the grain inside the sampling rod 10 into the sampling tube 3 through the connecting pipe 36 and the suction pipe 22, and then fall on the surface of the material tray 19. Under the gathering of the material tray 19, the grain uniformly falls onto the surface of the cylinder 26 through the through port 20. The No. 2 motor 14 drives the card The shaft 28 rotates, prompting each block 21 and rubber block 30 to drive the suction fan 23 and the cylinder 26 to rotate synchronously. The multiple groups of paddles 25 arranged between the two ash baffles 32 rotate by themselves when they come into contact with the falling grain. In the process of contact and turning the material, the grain and dust are separated. The suction fan 23 sucks in the dust and impurities, and the sampled grain falls into the open part of the discharge cylinder 17. Under the synchronous transmission of the No. 2 pulley assembly 15, the connecting shaft 18 inside the discharge cylinder 17 can be automatically discharged through the other end of the discharge cylinder 17. In this way, it can be ensured that the grain sampled later is more accurate and not affected by external factors such as dust. The sampled grain sample can accurately represent the actual storage status of the grain at the corresponding position and depth of the grain pile.
[0039] As described above, in order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.
