Description

Technical Field

[0001] The utility model belongs to the field of drying machines, and in particular relates to a grain-distributing device of a mobile corn drying machine. Background Art

[0002] In a dryer, a grain distribution tray is used to evenly distribute the grain inside the drying equipment to prevent grain from piling up near the entrance. This allows each grain to have adequate space to contact the hot air, ensuring the consistency of the drying effect and making the drying more uniform. However, the grain distribution components of current mobile grain dryers have dead corners during the distribution process, resulting in uneven drying of the grain and easily causing the grain to break.

[0003] Chinese patent publication number CN205747912U discloses a grain-distributing device for drying corn in a mobile dryer, which allows the grain to flow in an orderly manner inside the dryer, avoids dead corners in the grain, and reduces the grain breakage rate. At the same time, by rotating the screw with a crank, the nut can be moved back and forth, thereby driving the movement of the grain-distributing baffle, ultimately achieving the purpose of grain release. The limit block limits the movement of the grain-distributing baffle to prevent it from moving too much and affecting grain release. However, the moisture content of newly harvested corn is high and it is easy to stick together during the drying process. After the corn is stuck together into a ball, it is easy to roll between the first and second grain bows and the first and second grain racks. When the first and second grain bows move the corn ball, it is easy to drive the corn ball upward and continue to roll between the grain-distributing bow and the grain rack, making it difficult to break up the corn ball. The corn ball can only be broken up gradually by the weight of the upper corn layer, affecting the bottom grain release and the drying of the corn.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0016] 1. The driving motor in the grain-dividing mechanism drives the rotating column, grain-dividing part 1 and grain-dividing part 2 to rotate. Grain-dividing part 1 and grain-dividing part 2 simultaneously stir the corn in the drying barrel. If formed corn clumps appear, the corn clumps are mostly located in the area between grain-dividing part 1 and grain-dividing part 2 and cannot be directly stirred.

[0018] 3. Inclined surface 1 on the inner half of the grain dispensing piece, inclined surface 2 on the outer half, and the V-shaped discharge portion formed between inclined surface 1 and inclined surface 2 can guide the corn in the drying barrel to prevent the corn from piling up in the inner half. At the same time, the V-shaped discharge portion formed between inclined surface 1 and inclined surface 2 can guide the corn kernels into the grain discharge hole when the grain discharge hole is opened to prevent the corn from piling up in the middle of the drying barrel.

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-5 As shown, in this embodiment, a mobile corn dryer grain-dividing device is provided, including a grain-dividing plate 2 installed in a drying barrel 1 of the mobile dryer, and a discharge port 3 is opened at the bottom of the drying barrel 1. When the servo motor 7 installed on the outer wall of the drying barrel 1 drives the grain-dividing plate 2 to rotate through the gear 8 meshing with the tooth groove 6 at the bottom of the grain-dividing plate 2, if the grain-dividing plate 2 and the grain-discharging hole 5 on the fixed plate 4 coincide with each other, the corn will leak out from the discharge port 3 along the grain-discharging hole 5 for discharge. If the grain-dividing plate 2 and the grain-discharging hole 5 on the fixed plate 4 do not coincide with each other, the fixed plate 4 partially closes the grain-discharging hole 5 on the grain-dividing plate 2 as an opening. Of course, the grain-discharging speed can be adjusted by the overlap of the grain-discharging hole 5 on the fixed plate 4 and the grain-dividing plate 2. The higher the overlap of the two grain-discharging holes 5, the larger the opening, and the grain-discharging speed also increases accordingly.

[0031] like Figures 1 to 3 As shown, the grain allocation mechanism includes a driving motor 9, a rotating column 10, a grain allocation piece 11, a grain allocation piece 2 12 and a chain claw 13. The rotating column 10 is rotatably connected to the grain allocation plate 2. The grain allocation piece 11 and the grain allocation piece 2 12 are fixedly mounted on the rotating column 10. The chain claw 13 is mounted on the free end of the grain allocation piece 2 12. The driving motor 9 is mounted on the bottom of the fixed plate 4 and drives the rotating column 10 to rotate. When the driving motor 9 drives the rotating column 10, the grain allocation piece 11 and the grain allocation piece 2 12 to rotate, The grain-dividing part 11 stirs and / or divides the corn in the grain-dividing plate 2, while the grain-dividing part 2 12 stirs the corn at the bottom of the drying barrel 1. During this process, the chain claw 13 installed at the free end of the grain-dividing part 2 12 swings as the grain-dividing part 12 rotates. When located in the corn pile, due to the traction of the rotation of the grain-dividing part 2 12, the chain claw 13 moves irregularly between the grain-dividing part 11 and the grain-dividing part 2 12, breaking up the formed corn balls, and the chain of the chain claw 13 can also have a dividing effect.

[0032] Please review Figures 1 to 3 , the grain diverting device of the dryer adopts the above structure, when the corn is dried in the drying barrel 1, the driving motor 9 in the grain diverting mechanism drives the rotating column 10, the grain diverting part 11 and the grain diverting part 2 12 to rotate, and the grain diverting part 11 and the grain diverting part 2 12 stir the corn in the drying barrel 1 at the same time. If formed corn balls appear, since the corn balls are mostly located in the area between the grain diverting part 11 and the grain diverting part 2 12 and cannot be directly stirred, at this time, the rotating chain claw 13 of the grain diverting part 2 12 is pulled by the rotation of the grain diverting part 2 to break up the corn balls, thereby preventing the corn balls from affecting the bottom grain feeding and drying, and solving the problem in the prior art that the newly harvested corn has a high moisture content and is easy to stick together during the drying process. After the corn sticks into balls, it rolls between the grain diverting bow and the grain diverting rack, affecting the bottom grain feeding and drying of the corn.

[0033] like Figure 1 As shown, during the corn feeding process, the corn kernels are in irregular free fall motion, and the corn kernels may be stuck between the rotating parts of the drive motor 9, such as between the shaft and bearings of the drive motor 9, or be entangled in the winding, increasing the resistance to the operation of the drive motor 9 and causing the motor to short-circuit. Therefore, a protective tube 14 covering the drive motor 9 is provided at the bottom of the fixed plate 4 to block the corn kernels falling from above, so that the drive motor 9 can operate in a safe environment.

[0034] like Figure 2 As shown, in order to increase the mixing uniformity and avoid the situation where the grain-dividing part 11 and the grain-dividing part 2 12 rotate together, the corn kernels as a whole rotate along with the rotation center of the rotating column 10 in the drying barrel 1 instead of being stirred, a symmetrical installation method is used to make the diverting force generated by the grain-dividing part 11 and the grain-dividing part 2 12 more evenly distributed in the drying barrel 1, which helps to improve the diverting effect of the corn.

[0035] Please review Figure 1 In some cases, such as when the corn in the drying barrel 1 is unevenly distributed, there is less corn, the machine is being tested, or it is being touched by mistake, the grain-diverting part 12 may easily drive the chain claw 13 to idle, causing the chain claw 13 to contact the inner wall of the drying barrel 1. Since the chain claw 13 has a certain linear velocity and momentum during rotation, it will produce continuous impact and friction on the inner wall of the drying barrel 1, causing pits or deformation on the inner wall of the drying barrel 1. Therefore, it is necessary to limit the length of the chain claw 13 so that it will not contact the inner wall of the drying barrel 1 when idling, thereby increasing safety during idling and reducing damage to the drying barrel 1. At the same time, it is also necessary that the chain claw 13 does not contact the grain part 1 when it is hanging down, so as to prevent the chain claw 13 from gradually falling down and damaging the grain part 1 when rotating after idling.

[0036] like Figure 4As shown, in order to allow the conical front end to cut into the corn pile more smoothly, the claw end 1302 of the chain claw 13 and the side with the same rotation direction as the grain-distributing part 2 12 are set to a conical shape, so that the chain claw 13 can penetrate into the corn pile more effectively, break up and stir the agglomerated corn, and improve the mixing uniformity of the corn in the drying barrel 1.

[0037] like Figure 5 As shown, when the grain dispensing piece 11 rotates with the rotating column 10, the slope 1103 can guide the corn in the drying barrel 1, and the corn close to the rotation center begins to move outward under the action of the slope 1103, so that the corn can transition from the inner half 1101 to the outer half 1102 more smoothly, avoiding the accumulation of corn in the inner half 1101, and ensuring the flow continuity of corn on the grain dispensing piece 11, and the side of the outer half 1102 facing the rotation direction is provided with a slope 2 1104, and the corn transitioned from the inner half 1101 through the slope 1 1103 continues to move outward under the action of the slope 2 1104, and a V-shaped discharge part 1105 is formed between the slope 1103 and the slope 2 1104, which can play a guiding role when the grain discharge hole 5 is opened to prevent the corn from accumulating in the middle of the drying barrel 1.

[0038] Please review Figure 1 By fixing a plurality of spaced support brackets 15 on the inner wall of the drying barrel 1, the support brackets 15 share the load of the grain pan 2, thereby extending the service life of the grain pan 2.

[0039] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
