[0002] Grain is an essential item for our daily life. In various processes of grain processing, it is necessary to dry it to make its internal humidity reach an appropriate level to prevent mold, rot and pests from growing in the grain. In the process of grain drying, a special dryer is usually used. The dryer is also divided into fixed drying and transport drying. The appropriate dryer is selected according to different needs.

[0003] However, when the grain drying and conveying devices in the prior art are transporting grain, the grains are often piled up, which makes it difficult to fully expose the grains inside to the air, resulting in the situation that some grains are not dried thoroughly. In addition, during the drying process, only one side of the grains is often exposed to the air, which makes it difficult for the grains as a whole to be dried, resulting in a lack of drying effect.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the grain drying and conveying devices in the prior art often have grain stacking when transporting grain, making it difficult to expose the internal grain completely to the air, resulting in the situation that part of the grain is not dried thoroughly, and during the drying process, the grain is often only exposed to the air on one side, making it difficult for the grain to be dried as a whole, resulting in a lack of drying effect. A drying and conveying device for grain storage is proposed to solve the problem that the grain drying and conveying devices in the prior art often have grain stacking, making it difficult to expose the internal grain completely to the air, resulting in a lack of drying effect.

[0008] Furthermore, a material discharge box is commonly fixed to the top of one side of the two baffles, a material feed hopper is fixed to the top of the material discharge box, and two rotating augers are rotatably connected to the interior of the material discharge box.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] This embodiment aims to solve the problem that grains are often piled up when grains are transported by grain drying and conveying devices in the prior art, making it difficult to fully expose the grains inside to the air, resulting in insufficient drying of some grains.

[0024] like Figure 1 and Figure 5As shown, a drying and conveying device for grain storage comprises a base 1, a drying box 2 is fixed to one side of the upper surface of the base 1, an observation window is fixed to the front end of the drying box 2, and the drying work inside is observed through the observation window, and a fan access port 28 is fixed to one side of the base 1, and an external fan is fixed to one side of the fan access port 28, and the impurities inside are sucked out by the external fan, two baffles 3 are symmetrically fixed to the front and rear ends of the upper surface of the base 1, two sieve plates 11 are arranged between the two baffles 3, a support frame 10 is fixed to the top ends of the two baffles 3, and a dispersion mechanism 4 is installed inside the support frame 10, and the dispersion mechanism 4 comprises a first motor 5 fixed to the front end of the support frame 10, and the transmission end of the first motor 5 penetrates and extends to the support frame 10, and a turntable 19 is fixed inside, and an eccentric block 15 is fixed to the rear end of one side of the turntable 19, and the outer layer of the eccentric block 15 is sleeved with a curved block 18;

[0025] Two first connecting rods 16 are symmetrically fixed on both sides of the curved block 18, a sliding rod 14 is fixed on one side of the first connecting rod 16, a fixed sleeve 13 fixed inside the support frame 10 is inserted and connected to one side of the sliding rod 14, and a second connecting rod 20 that penetrates and extends to the outside of the fixed sleeve 13 is fixed to the bottom of one side of the sliding rod 14, a through groove 27 is opened at the bottom of the fixed sleeve 13 corresponding to the position of the second connecting rod 20, and a dispersion roller 17 is fixed to the bottom end of the second connecting rod 20. The two dispersion rollers 17 are designed to be at an inclined angle, and there is an appropriate distance between the dispersion rollers 17 and the screen plate 11, so that there will be no collision due to the vibration of the screen plate 11, and the grain at the moving height can be dispersed and flattened.

[0026] When the grain falls onto the upper surface of the sieve plate 11, the vibration of the sieve plate 11 drives the grain to move slowly. When the grain moves to the position of the support frame 10, the first motor 5 is started to drive the turntable 19 to rotate. The rotation of the turntable 19 drives the eccentric block 15 to move in a circular motion. The circular motion of the eccentric block 15 drives the curved block 18 to reciprocate horizontally. The curved block 18 is used to drive the sliding bars 14 on both sides to reciprocate horizontally through the first connecting rod 16. The sliding bar 14 drives the second connecting rod 20 to reciprocate and then drives the dispersion roller 17 to reciprocate to disperse the grain, flatten the stacked grains, expose the grains below to the air, and improve the overall drying efficiency.

[0027] Embodiment 2:

[0028] In order to solve the problem in the prior art that only one side of the grain is exposed to the air during the drying process, making it difficult for the grain to be dried as a whole, resulting in a poor drying effect, this embodiment proposes a drying and conveying device for grain storage.

[0029] like Figure 2-Figure 4As shown, the embodiment is a drying and conveying device for grain storage, and a feed box 8 is fixed to the top of one side of two baffles 3, a feed hopper 9 is fixed to the top of the feed box 8, and two rotary screws 12 are rotatably connected inside the feed box 8, and the front end of the rotary screw 12 penetrates and extends to the outside of the feed box 8 and is fixed with a gear 7, and the front end of one of the gears 7 is connected to a second motor 6 fixed to the front end of the feed box 8;

[0030] A number of vibration motors 26 are fixed equidistantly between the two sieve plates 11. The sieve plates 11 are at an angle to the horizontal line. As the sieve plates 11 vibrate, the grain is driven to move. Two connecting plates 24 are symmetrically fixed to the front and rear ends of the two sieve plates 11. A number of connecting blocks 25 are equidistantly fixed to the surface of one end of the connecting plate 24. A placement cavity 23 is provided on the inner side of the baffle 3 at a position corresponding to the connection block 25. A fixed block 22 is provided inside the placement cavity 23. Springs 21 are fixed at the upper and lower ends of the fixed block 22 inside the placement cavity 23. Support is formed by the spring 21. When vibrated, the spring 21 forms a reset stretch on the fixed block 22, and one end of the fixed block 22 is fixed to the connecting block 25.

[0031] Grain is put into the feed hopper 9, and the second motor 6 is started to drive one of the gears 7 to rotate. The rotation of the gear 7 drives the other gear 7 to rotate. The rotation of the two gears 7 drives the two rotary screw dragons 12 to rotate. The rotation of the rotary screw dragon 12 drives the grain to slowly fall to the upper surface of the sieve plate 11, and the vibration motor 26 is started to drive the two sieve plates 11 to vibrate. The vibration of the sieve plate 11 drives the connecting plate 24 to vibrate. The connecting plate 24 drives the connecting block 25 to vibrate and transmits it to the fixed block 22. The fixed block 22 cooperates with the spring 21 to assist the sieve plate 11 to perform the vibrating effect. During the vibration of the sieve plate 11, the grain is driven to move, and the grain is turned over so that its surface can be in contact with the air. During the vibration of the grain, some small impurities will also fall into the base 1, and are connected through the external fan and the fan inlet 28 to suck out the internal impurities. The grain is moved to the inside of the drying box 2 for drying, thereby improving the overall drying efficiency.

[0032] The working process and principle of the utility model are as follows:

[0033] Step 1: Put grains through the feed hopper 9, start the second motor 6 to drive one of the gears 7 to rotate, the rotation of the gear 7 drives the other gear 7 to rotate, the rotation of the two gears 7 drives the two rotating augers 12 to rotate, the rotation of the rotating augers 12 drives the grains to slowly fall to the upper surface of the sieve plate 11;

[0034] Step 2: After the grain falls onto the upper surface of the sieve plate 11, the vibration of the sieve plate 11 drives the grain to move slowly. When the grain moves to the position of the support frame 10, the first motor 5 is started to drive the turntable 19 to rotate. The rotation of the turntable 19 drives the eccentric block 15 to move in a circular motion. The circular motion of the eccentric block 15 drives the curved block 18 to reciprocate horizontally. The curved block 18 drives the sliding bars 14 on both sides to reciprocate horizontally through the first connecting rod 16. The sliding bar 14 drives the second connecting rod 20 to reciprocate and then drives the dispersion roller 17 to reciprocate to disperse the grain, flatten the stacked grains, expose the grains below to the air, and improve the overall drying efficiency.

[0035] Step three: Start the vibration motor 26 to drive the two sieve plates 11 to vibrate. The vibration of the sieve plates 11 drives the connecting plates 24 to vibrate. The connecting plates 24 drive the connecting blocks 25 to vibrate and transmit the vibration to the fixed blocks 22. The fixed blocks 22 cooperate with the springs 21 to assist the sieve plates 11 in vibrating. During the vibration of the sieve plates 11, the grains are driven to move and at the same time, the grains are turned over so that their surfaces can come into contact with the air. During the vibration of the grains, some small impurities will fall into the base 1 and be connected to the fan inlet 28 through an external fan to suck out the internal impurities. The grains are moved to the drying box 2 for drying, thereby improving the overall drying efficiency.

[0036] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
