Description

Technical Field

[0001] The utility model relates to wheat drying equipment, in particular to wheat drying equipment, and belongs to the technical field of agricultural product processing. Background Art

[0002] At present, after wheat is harvested, it needs to be air-dried or dried before it can be stored in a warehouse. The traditional air-drying method is to directly dry the wheat in the sun over a large area or dry it in the shade before collecting and storing it. This method is very time-consuming and labor-intensive, and will be affected by the weather. In addition, the following problems may occur: In the sun-drying method, since the surface of the wheat is exposed to sunlight, the surface temperature is high, the wheat loses moisture quickly, and the degree of drying is difficult to control. For example, due to exposure to the sun, it is easy to cause inconsistent water removal inside and outside the wheat, and even cracks in the wheat, which destroys the integrity of the wheat; in the shade-drying method, it is more obviously affected by weather conditions, especially on rainy days, the wheat dries slowly, and even the wheat does not dry to the required degree for a long time and causes deterioration; and after the wheat is dried, it needs to be screened to remove internal impurities before it can be collected and stored.

[0003] According to a wheat drying device disclosed in a Chinese patent document with a publication number of CN208805024U, the drying device includes a drying box, a rotating shaft vertically arranged in the drying box, a motor arranged on the top of the drying box for driving the rotating shaft to rotate, a drying plate made of a mesh plate arranged in the lower part of the drying box, a hollow air collecting pipe connected to the lower end of the rotating shaft, the air collecting pipe is connected to a horizontally arranged exhaust pipe, a plurality of jet hoods are arranged on the exhaust pipe, a hot air blower is arranged on the outer side of the drying box, the air outlet of the hot air blower is connected to a hot air pipe, the hot air pipe is connected to the air collecting pipe through a rotary joint, and a stirring rod with one end fixed on the rotating shaft is horizontally arranged above the drying plate. The utility model can play a role in uniformly drying wheat when drying wheat, so that the drying device has a better effect when drying wheat, and its structure is simple, easy to operate, energy saving, and can greatly improve the efficiency of wheat drying.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that although the above equipment solves the problem of uniform drying of wheat when used, it is impossible to filter out impurities inside the wheat during the drying process using the above equipment. Therefore, before or after drying the wheat, a screening process needs to be added to ensure that the wheat meets the standards for collection and storage in the later stage. Therefore, adding a screening process during the wheat drying process will greatly reduce the efficiency of wheat processing, collection and storage. Although some existing drying equipment can screen the wheat during the drying process, it is only a screening process, resulting in poor filtering effect on the wheat and some impurities will be missed.

[0005] Therefore, it is urgent to improve the wheat drying equipment to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a wheat drying device, which can not only realize efficient and uniform drying of wheat, but also can perform multiple filtration of impurities in the wheat during the drying process, so that the wheat processed later can fully meet good collection standards.

DETAILED DESCRIPTION

[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] like Figure 1-Figure 6 As shown, the wheat drying equipment provided in this embodiment includes a drying bin 1, both ends of the drying bin 1 are supported by a support body 2, and the two ends of the drying bin 1 are respectively connected with an air inlet duct 3 and an exhaust duct 4 rotatably connected to the support body 2, and a bearing 12 is provided on the support body 2, and the air inlet duct 3 and the exhaust duct 4 are respectively connected with two bearings 12;

[0029] A driving mechanism 5 for driving the drying chamber 1 to rotate is disposed on one of the supporting bodies 2; Figure 2As shown, the driving mechanism 5 includes a driving motor 13 supported on the outside of one of the supporting bodies 2, a first gear 14 connected to the output shaft of the driving motor 13, and a second gear 15 provided on the air inlet duct 3 and meshingly connected to the first gear 14. The driving motor 13 drives the first gear 14 to rotate, and then drives the meshing second gear 15 and the air inlet duct 3 to rotate, thereby driving the drying chamber 1 to rotate;

[0030] A heating mechanism 8 for heating the interior of the drying chamber 1 is arranged inside the air inlet duct 3;

[0031] Further, such as Figure 4 As shown, the heating mechanism 8 includes a fan 801 arranged inside the air inlet duct 3 and with the wind direction facing the drying bin 1, and a plurality of groups of heating wires 802 arranged inside the air inlet duct 3. The heating wires 802 are located at the blowing end of the fan 801. When the wheat enters the drying bin 1 and the drying bin 1 is rotated, the fan 801 is used to blow the heat generated by the plurality of groups of heating wires 802 into the drying bin 1 to dry the wheat that is rotating and stirring. At the same time, while the hot air is drying, the impurities in the wheat being stirred will be filtered. The light impurities that fall off the wheat during stirring will be blown into the exhaust duct 4 by the generated hot air, and finally collected and processed in the collection bin 11.

[0032] The upper end surface of the drying bin 1 is hinged with a filter cover plate 6, wherein the filter cover plate 6 is locked with the upper end surface of the drying bin 1 by means of a lock buckle and a lock member. When wheat is put in, it is opened. After the wheat is put in, the filter cover plate 6 is fixed by means of the lock buckle and the lock member to prevent the filter cover plate 6 from being separated when the drying bin 1 is rotated.

[0033] Further, such as Figure 4 As shown, stirring arms 22 are staggeredly arranged inside the drying bin 1. The staggered stirring arms 22 can stir the wheat inside to improve the uniformity of drying. The ends of the air inlet duct 3 and the discharge duct 4 connected to the drying bin 1 are both connected with trumpet-shaped diffusers 23. The diffusers 23 on the air inlet duct 3 can maximize the range of hot air generated by the heating mechanism 8, thereby improving the drying range of the wheat inside the drying bin 1. The diffuser 23 on the discharge duct 4 makes it easy to collect lighter floating objects in the wheat, so that they can smoothly enter the collection bin 1 for collection.

[0034] The lower end surface of the drying bin 1 is connected with a discharge pipe 7, a filter plate 9 is arranged inside the discharge pipe 7, and a sealing plate 10 is hingedly arranged on the lower end surface of the discharge pipe 7;

[0035] Further, such as Figure 5 and Figure 6As shown, a pull-out sealing plate 16 is provided at the upper end of the discharge pipe 7. The pull-out sealing plate 16 is provided in a state of sealing the discharge pipe 7 when the drying bin 1 is in operation, so as to prevent the wheat in the drying bin 1 from entering the discharge pipe 7, and can be pulled out during discharge later; a discharge port 17 is provided on one side of the lower end of the discharge pipe 7, and the sealing plate 10 is used to seal the discharge port 17. The discharge port 17 is used to discharge the wheat that has finally been dried and filtered, and the filter plate 9 is tilted inside the discharge pipe 7, and the top end of the filter plate 9 is fixedly connected to a side of the discharge pipe 7 away from the discharge port 17, and the lowest end of the filter plate 9 is fixedly connected to a side of the lower end of the discharge pipe 7 close to the discharge port 17, and a pull-out collecting box 18 slidably connected to the discharge pipe 7 is provided below the filter plate 9; When discharging through the discharge pipe 7, the pull-out sealing plate 16 is pulled out. It should be noted that when the pull-out sealing plate 16 is pulled out, the drying bin 1 can be rotated and tilted first, so that the wheat inside does not cause pressure on the pull-out sealing plate 16, so as to facilitate the pull-out sealing plate 16 to be pulled out later, and then the sealing plate 10 is opened, and the drying bin 1 is rotated to the state where the discharge pipe 7 is vertically downward. At this time, the wheat inside the drying bin 1 that has been dried and filtered twice is discharged. When discharging, the wheat will slide through the filter plate 9. In the process of wheat sliding, impurities will fall through the filter plate 9 to the pull-out collection box 18 for collection and processing, and the wheat will be discharged for collection after filtration, and the inside of the pull-out collection box 18 can be cleaned later;

[0036] The pull-out sealing plate 16 is locked with the outer side of the discharge pipe 7 by means of a lock buckle and a lock piece, and the sealing plate 10 is locked with the lower end of the discharge pipe 7 and the pull-out collecting box 18 is locked with the outer side of the discharge pipe 7 by means of a lock buckle and a lock piece. The above structures are locked by means of a lock buckle and a lock piece to prevent the pull-out sealing plate 16, the pull-out collecting box 18 and the sealing plate 10 from being separated from the equipment when the drying bin 1 is rotating. When the drying bin 1 stops running for discharge later, the lock mouth and the lock piece can be opened;

[0037] The exhaust end of the exhaust duct 4 is connected to a collection bin 11; Figure 4 As shown, a cover plate 19 is hingedly provided on one side of the collecting bin 11. The setting of the cover plate 19 makes it easy to clean the exhaust duct 4 and the collecting bin 11 later. The lower end of the collecting bin 11 is connected to a discharge pipe 20, and the discharge pipe 20 is sealed by a sealing plug 21. When the impurities in the collecting bin 11 need to be discharged later, the sealing plug 21 is pulled out to discharge and clean the impurities inside the collecting bin 11. The cover plate 19 is locked to the collecting bin 11 by a lock and a lock to prevent the cover plate 19 from being separated from the collecting bin 11 when the drying bin 1 is rotated.

[0038] like Figure 1-Figure 6As shown, the principle of the wheat drying equipment provided by this embodiment is as follows: when in use, open the filter cover 6, put the wheat into the drying bin 1, and then close the filter cover 6, and drive the drying bin 1 to rotate through the driving mechanism 5. It should be noted that the rotation speed of the drying bin 1 itself is not fast. During the rotation of the drying bin 1, the heating mechanism 8 inside the air inlet duct 3 is used to dry the wheat being stirred inside the drying bin 1. During the drying process, the hot air generated by the heating mechanism 8 is used to blow the light impurities that fall off the wheat during stirring into the exhaust duct 4, and the light impurities are collected and processed in the collection bin 11, so as to achieve the effect of preliminary removal of impurities. At the same time, during the rotation of the drying bin 1, Since the filter cover 6 itself has a filtering effect, when the drying bin 1 rotates to the point where the filter cover 6 is at the bottom, the impurities in the wheat will be filtered again through the filter cover 6, and the filtered impurities will fall directly on the ground and can be cleaned up later. When the impurities inside the drying bin 1 are dried and double filtered, they are discharged. When discharged, the wheat will slide through the filter plate 9. In the process of the wheat sliding down, the impurities will pass through the filter plate 9 and fall into the pull-out collection box 18 for collection and treatment, thereby achieving the effect of re-filtration. The wheat will be discharged for collection after filtration, and the inside of the pull-out collection box 18 can be cleaned later, so that the discharged wheat can fully meet the good collection standards.
