Description

Technical Field

[0001] The utility model relates to the technical field of grain drying, in particular to a grain processing and drying device. Background Art

[0002] When the temperature and humidity conditions in the environment where the grain is located meet the growth and reproduction of microorganisms, mildew will occur. That is to say, moisture and temperature are two important factors for the reproduction of microorganisms such as molds in grains (i.e., grain mildew). Generally, controlling the grain moisture below the safe moisture can prevent grain mildew.

The efficiency of direct sun drying is low, and traditional drying devices dry the grain by heating. The grain particle size is one of the important factors determining grain quality. Traditional drying devices cannot carry out the drying work and screening work well at the same time during the drying process, resulting in low grain processing efficiency, increasing the subsequent operation time, and being time-consuming and laborious.

[0031] The working principle of the present utility model is as follows: During actual production and use, when it is necessary to dry grains, the tilting mechanism can be operated to drive the drying and screening mechanism to tilt by the tilting mechanism, so that the material port tilts upward. Then, the grains are put into the first sieve cylinder 27 through the material port. Subsequently, the heating and drying component and the rotation driving component are simultaneously operated, so that the rotation driving component drives the first sieve cylinder 27, the second sieve cylinder 24 and the third sieve cylinder 22 to rotate through the outer barrel 8, so that the grain particles inside the first sieve cylinder 27 pass through the first sieve holes 25 and enter the second sieve cylinder 24.

[0035] Further, the rotation driving component includes a mounting block 13, a rotation driving member 14, a first gear 1 and a second gear 12. The first gear 1 is sleeved outside the outer barrel 8.

The rotation driving member 14 is drivingly connected to the second gear 12.

[0036] As can be seen from the above description, when it is necessary to rotate the outer barrel 8, the first sieve cylinder 27, the second sieve cylinder 24 and the third sieve cylinder 22, the rotation driving member 14 can be operated, so that the rotation driving member 14 drives the first gear 1 to rotate through the second gear 12, thereby driving the outer barrel 8 to rotate by the first gear 1, and driving the first sieve cylinder 27, the second sieve cylinder 24 and the third sieve cylinder 22 to rotate synchronously, facilitating the better contact heating of the grain with the heating rods 11 and enabling the better screening of the grain.

One end of the first linear driving member 6 is rotatably connected to the base 7. The other end of the first linear driving member 6 is drivingly connected to the other end of the frame 9. The outer barrel 8 is rotatably connected to the frame 9. The mounting block 13 is arranged on the upper part of the frame 9.

[0038] As can be seen from the above description, when it is necessary to discharge the grain outside the device for collection, the first linear driving member 6 can be operated, so that the first linear driving member 6 drives the drying and screening mechanism to tilt through the frame 9, making the material outlet face downward, so that the grain in the drying and screening mechanism can be better poured out of the device for collection.

[0039] Further, the discharging assembly includes a second linear driving member 2, a sliding rod 5, a cover plate 4, a first blocking member 20, a second blocking member 19, and a third blocking member 21.

The third blocking member 21 is slidably connected between the third sieve cylinder 22 and the outer barrel 8. The second linear driving member 2 is linearly drivingly connected to the cover plate 4. A through hole 3 is arranged in the middle of the cover plate 4, and the through hole 3 communicates with the first sieve cylinder 27.

[0040] As can be seen from the above description, when it is necessary to discharge the dried and screened grains, the tilting mechanism can be operated to tilt the drying and screening mechanism. Subsequently, the grains in the first sieve cylinder 27 are discharged outside the device through the through hole 3 for collection. Then, the second linear driving member 2 is operated to drive the first blocking member 20, the second blocking member 19, and the third blocking member 21 to move through the cover plate 4 by the first linear driving member 6, so that the first blocking member 20 first disengages between the first sieve cylinder 27 and the second sieve cylinder 24, and the grains in the second sieve cylinder 24 are first discharged outside the device. Subsequently, the cover plate 4 is continuously pushed to make the second blocking member 19 disengage between the second sieve cylinder 24 and the third sieve cylinder 22, so that the grains in the third sieve cylinder 22 are discharged outside the device. Finally, the third blocking member 21 disengages between the third sieve cylinder 22 and the outer barrel 8, so that the grains in the outer barrel 8 are discharged outside the device.

[0041] Further, a PLC controller is further included, and the PLC controller is electrically connected to the drying and screening mechanism and the tilting mechanism respectively.

[0042] As can be seen from the above description, it is beneficial to adjust the parameters of the grain processing and drying equipment through the PLC controller, and make it more convenient for the operator to operate the grain processing and drying equipment.
