Description

Technical Field

[0001] The utility model relates to the technical field of grain drying equipment, in particular to a grain spreading plate of batch-type circulating grain drying equipment. Background Art

[0002] Grain dryers are used to dry grains such as corn, wheat, rice, and rapeseed. There is a drying box in the grain machine. The dried grains enter the grain discharge box. After being discharged from the grain discharge box, the grains are lifted back to the upper part of the drying box by the elevator for slow recovery, and then heated again and released into the grain discharge box. This process is repeated many times to achieve the purpose of completely drying the grains.

[0003] Referring to the patent publication number CN203279772U, a new type of batch grain dryer grain spreading device, the existing batch circulating grain dryer usually includes a rectangular grain spreading bin, which is equipped with a grain spreading disk, which is generally a disc-shaped structure. During the grain spreading process, the motor drive device is turned on to drive the rotating shaft to rotate, and then drive the grain spreading disk and the blades to rotate together to form a grain spreading action with a fixed diameter. However, this grain spreading action often cannot completely cover the entire rectangular grain spreading bin, resulting in the possibility of grain accumulation or uneven distribution during the grain spreading process, affecting the drying effect and grain quality. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a grain spreading plate for batch circulation grain drying equipment, improves the shape and structure of the grain spreading plate so that it can better cooperate with the grain spreading bin to achieve uniform spreading of grain.

[0005] In order to achieve the above-mentioned purpose, the grain scattering plate of the batch circulation grain drying equipment adopted by the utility model includes a grain scattering component, which is installed in a rectangular grain scattering space, and the grain scattering component includes a circular plate body, and a baffle wall is provided on the outer edge of the circular plate body to form a grain receiving space to receive the grain falling from the top, and the baffle wall is evenly arranged along the circumferential direction. Four openings for grain outflow, a rotating rod is connected to the center of the circular plate body to enable the circular plate body to rotate with the rotating rod, and the top of the rotating rod is connected to a driving component for driving the rotating rod to rotate, and the outer surface of the rotating rod is connected to four guide plates, and the edge parts of the guide plates pass through the openings, and two adjacent guide plates have a length difference, and the lengths of the two guide plates arranged opposite to each other are the same.

[0006] The utility model improves the shape and structure of the grain spreading plate to achieve the purpose of optimizing the grain distribution during the grain spreading process and improving the grain spreading efficiency and uniformity. The traditional cylindrical grain spreading path is abandoned, and there is an uneven structure with a high middle and low sides in the grain spreading space, which leads to uneven grain accumulation and affects the grain spreading effect. To this end, the utility model introduces a grain spreading plate with two long and two short structural guide plates, which induces the grain to form an elliptical grain spreading path, which is more in line with the rectangular grain spreading space, so that the scattered grain can be piled relatively flat, thereby improving the utilization rate of the grain spreading space and the uniformity of grain distribution.

[0007] As a further optimization of the above solution, a plurality of grain discharge openings are provided on the bottom plate of the circular disk body, the retaining wall is inclined from the center of the circular disk body toward the grain spreading space, and the top edge of the retaining wall is higher than the top wall of the opening.

[0008] The above structure makes the grain spreading plate have three grain spreading paths. The first path exists in the grain discharge port and leaks out from the bottom of the grain spreading plate. The second path is an open path where the largest amount of grain is discharged. The third path is when the grain spreading plate is filled, and the grain is thrown out from the edge of the baffle wall using the inclined baffle wall. The above three discharge paths work together to ensure that the grain can be effectively released from the grain spreading plate and evenly distributed in the target area, ensuring the maximization of the grain spreading effect and minimization of grain accumulation.

[0009] As a further optimization of the above scheme, the guide plate has an arc-shaped first part and a second part along the path from the rotating rod to the opening, the convex surface of the first part and the concave surface of the second part are located in the same grain flow direction so that the guide plate forms an S-shaped structure, and the convex surface of the second part contacts the opening.

[0010] By improving the guide plate into an arc-shaped structure, the load is dispersed in different directions, the flow of the grain fluid is smoothed, and higher structural strength and stability are provided.

[0011] As a further optimization of the above scheme, the first part is externally connected to a hollow tube, and the second part is equipped with a connecting tube passing through the hollow part of the hollow tube. The inner walls of the hollow tube and the connecting tube are respectively provided with a first internal thread and a second internal thread. The first internal thread and the second internal thread are located in the same vertical plane, and the locking bolt passes through the first internal thread and the second internal thread to fix the hollow tube and the connecting tube.

[0012] The above structure effectively transmits torque and enhances the stability of the connection through the coordinated use of internal and external threads. At the same time, the use of locking bolts increases the overall stability of the structure and reduces the risk of loosening due to vibration and other reasons.

[0013] The grain spreading plate of the batch cycle grain drying equipment of the utility model has the following beneficial effects:

[0014] 1. The grain spreading plate of the batch-type circulating grain drying equipment of the utility model improves the shape and structure of the grain spreading plate to achieve the purpose of optimizing the grain distribution during the grain spreading process. The technical problems such as the uneven structure of the grain spreading space with a high middle and low sides in the traditional cylindrical grain spreading path are abandoned, which leads to uneven grain accumulation and affects the grain spreading effect. To this end, the utility model introduces a grain spreading plate with two long and two short structural guide plates, which induces the grain to form an elliptical grain spreading path, which is more in line with the rectangular grain spreading space, so that the scattered grain can be piled relatively flat, thereby improving the utilization rate of the grain spreading space and the uniformity of grain distribution.

[0015] 2. The grain spreading plate of the batch circulation grain drying equipment of the utility model has three grain spreading paths. The first path exists in the grain discharge port and leaks out from the bottom of the grain spreading plate. The second path is an open path where the largest amount of grain is discharged. The third path is when the grain spreading plate is filled, and the grain is thrown out from the edge of the baffle wall using the inclined baffle wall. The above three discharge paths work together to ensure that the grain can be effectively released from the grain spreading plate and evenly distributed in the target area, thereby ensuring the maximization of the grain spreading effect and minimization of grain accumulation.

[0016] 3. The grain spreading plate of the batch circulation grain drying equipment of the utility model effectively transmits torque and enhances the stability of the connection through the coordinated use of internal and external threads. At the same time, the use of locking bolts increases the stability of the overall structure and reduces the risk of loosening due to vibration and other reasons.
