Description

Technical Field

[0001] This utility model belongs to the field of agricultural product processing technology, specifically a drying device for agricultural product processing with a turning effect. Background Technology

[0002] In the field of agricultural product processing, drying is a crucial processing method. Its purpose is to reduce the moisture content of agricultural products, inhibit the growth and reproduction of microorganisms, extend the shelf life of agricultural products, and improve the quality and added value of agricultural products. With the advancement of agricultural modernization, increasingly higher requirements are being placed on the performance, efficiency, and automation level of agricultural product drying equipment.

[0003] Currently, there are various types of agricultural product drying equipment on the market. The most common ones are traditional hot air drying rooms, which use hot air blowers to send hot air into the room to dry agricultural products placed on trays. There are also drum dryers, which use the rotation of the drum to make the agricultural products tumble inside the drum while hot air is introduced to achieve drying. In addition, there are also some devices that use vacuum freeze drying, solar drying, microwave drying and other technologies.

[0004] However, these existing drying devices have some shortcomings. The air circulation in traditional hot air drying rooms is often not uniform enough, resulting in uneven heating of agricultural products. Some agricultural products may be over-dried while others are under-dried, which seriously affects the consistency of drying quality. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a drying device for agricultural product processing with a turning effect, which solves some of the shortcomings of existing drying devices. The air circulation in traditional hot air drying rooms is often not uniform enough, resulting in uneven heating of agricultural products. Some agricultural products may be over-dried while others are under-dried, which seriously affects the consistency of drying quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for agricultural product processing with a turning effect, comprising an outer barrel, a first side plate and a second side plate being snap-connected to both sides of the outer barrel, an inner cylinder being rotatably connected to the first side plate and the second side plate, a motor being fixedly connected to the outer side plate of the second side plate, a transmission rod being coaxially fixedly connected to the output end of the motor, the transmission rod being located inside the inner cylinder, and a turning mechanism being fixedly connected to the outer side of the transmission rod, a drive gear being rotatably connected to the inner side of the second side plate, and the drive gear being fixedly connected to the transmission rod. The second side plate has a semi-circular slot, and a fixed rod is fixedly connected to the top of the slot. A driven gear that works with the drive gear is rotatably connected to the inner side of the fixed rod. An internal gear ring that works with the driven gear is provided on the inner side of the inner cylinder. Support legs are fixedly connected to the outer side of the outer cylinder in a symmetrical structure. A base is slidably connected to the outer side of the bottom of the support legs. An electric telescopic rod is fixedly installed between the base and the support legs in a symmetrical structure. A blower mechanism that works with the inner cylinder is installed inside the outer cylinder. Multiple sets of ventilation holes that work with the blower mechanism are provided on the inner cylinder.

[0007] As a further embodiment of this utility model: the flipping mechanism includes a connecting rod, the connecting rod is fixed to the outside of the transmission rod, and a scraper is fixedly connected to the outer end of the connecting rod, the scraper having a semi-arc structure.

[0008] As a further embodiment of this utility model: the blower mechanism includes an air guide pipe, the top two ends of the air guide pipe are connected to air supply rings, multiple sets of exhaust pipes are connected and fixed between the air supply rings, multiple sets of nozzles are provided inside the exhaust pipes, and an air supply mechanism is connected to the outside of the air guide pipes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The transmission rod drives the turning mechanism to rotate clockwise. Its semi-circular scraper adheres to the inner wall of the inner cylinder, turning the material near the cylinder wall towards the center, breaking up the piled-up state and dispersing the clumps. At the same time, the transmission rod drives the drive gear to rotate clockwise. Through meshing with the driven gear and the internal gear ring, it forces the inner cylinder to rotate counterclockwise, forming a compound motion of high-speed stirring of the turning mechanism and low-speed rotation of the inner cylinder in the opposite direction.

[0013] 2. The combined motion causes the material to be both thrown up and turned inside the cylinder, and to move around with the inner cylinder, avoiding local accumulation. The blower mechanism blows hot air from the outside of the inner cylinder into the cylinder from 360° through the air guide pipe, air supply ring, and annularly arranged exhaust pipe and nozzles. The hot air penetrates the material layer through the ventilation holes.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-5 As shown, this utility model provides a technical solution:

[0022] A drying device for agricultural product processing with a turning effect includes an outer barrel 1. A first side plate 5 and a second side plate 6 are snap-fitted together on both sides of the outer barrel 1. An inner cylinder 8 is rotatably connected to the first side plate 5 and the second side plate 6. A motor 7 is fixedly connected to the outer side of the second side plate 6. A transmission rod 16 is coaxially fixedly connected to the output end of the motor 7. The transmission rod 16 is located inside the inner cylinder 8, and a turning mechanism is fixedly connected to the outer side of the transmission rod 16. A drive gear 9 is rotatably connected to the inner side of the second side plate 6 and is fixedly connected to the transmission rod 16. A semi-circular opening is formed on the second side plate 6. The inner cylinder 8 has a slotted shape, and a fixed rod 10 is fixedly connected to the top of the slot. A driven gear 11 that works with the drive gear 9 is rotatably connected to the inner side of the fixed rod 10. An internal gear ring 12 that works with the driven gear 11 is provided on the inner side of the inner cylinder 8. A support leg 2 is fixedly connected to the outer side of the outer cylinder 1 in a symmetrical structure. A base 3 is slidably connected to the outer side of the bottom of the support leg 2. An electric telescopic rod 4 is fixedly installed between the base 3 and the support leg 2 in a symmetrical structure. A blower mechanism that works with the inner cylinder 8 is installed inside the outer cylinder 1. Multiple sets of ventilation holes that work with the blower mechanism are opened on the inner cylinder 8.

[0023] Specifically, during use, the motor 7 is started, which drives the turning mechanism to rotate clockwise via the transmission rod 16, stirring and scattering the material to break up the material accumulation and facilitate the rapid dispersion of clumps, thereby increasing the contact area between the material and the hot air. The transmission rod 16 drives the drive gear 9 to rotate clockwise, and the drive gear 9 meshes with the driven gear 11. Since the driven gear 11 meshes with the internal gear ring 12, it forces the inner cylinder 8 to rotate counterclockwise. The high-speed stirring of the turning mechanism and the low-speed rotation of the inner cylinder 8 in the opposite direction form a compound motion, so that the material is both thrown up and turned in the cylinder and moves in the circumference with the inner cylinder 8, avoiding local accumulation. The blower mechanism blows hot air into the cylinder through the ventilation holes. The hot air passes through the material layer and takes away the moisture. The multiple sets of ventilation holes ensure that the airflow is evenly covered. At the same time, the electric telescopic rod 4 extends and retracts periodically, driving the support leg 2 to slide along the base 3, so that the outer cylinder 1 makes a small linear reciprocating motion, which can shake away the material that may be stuck in the gap between the inner cylinder 8 and the turning mechanism, avoiding mechanical blockage.

[0024] The flipping mechanism includes a connecting rod 17, which is fixed to the outside of the transmission rod 16, and a scraper 18 is fixedly connected to the outer end of the connecting rod 17. The scraper 18 has a semi-arc structure. The blower mechanism includes an air guide pipe 13, and air supply rings 15 are connected to the top two ends of the air guide pipe 13. Multiple sets of exhaust pipes 14 are fixedly connected between the air supply rings 15. Multiple sets of nozzles are provided inside the exhaust pipes 14, and an air supply mechanism is connected to the outside of the air guide pipe 13. The exhaust pipes 14 surround the outside of the inner cylinder 8 in a ring structure.

[0025] Specifically, when the semi-arc scraper 18 rotates with the transmission rod 16, its arc structure can fit against the inner wall of the inner cylinder 8, increasing the contact area with the material and enabling the material to turn from the cylinder wall to the center, avoiding the accumulation of material near the cylinder wall. During the turning process, the scraper 18 can bring the bottom material to the upper layer, allowing it to fully contact the hot airflow sprayed by the blower mechanism, while breaking the adhesion between the materials, ensuring that the surface of each agricultural product can be heated evenly, reducing the drying blind spots. The air supply ring 15 and multiple sets of annularly arranged exhaust pipes 14 form a "circumferential" airflow coverage. The hot airflow is sprayed out at high pressure through the nozzle, which can penetrate the ventilation holes 360° from the outside of the inner cylinder 8, ensuring that the material around the inner cylinder 8 can contact the airflow, avoiding the uneven drying problem caused by traditional single-sided air supply.

[0026] The first side plate 5 has a feed inlet at the top, the second side plate 6 has a discharge outlet at the bottom, and the base 3 has a movable groove on one side for use with the discharge outlet. The inner side of the base 3 is fixedly connected with a limit block in a symmetrical structure. The outer side of the support leg 2 has a sliding groove for use with the limit block, and the two sides of the support leg 2 have chamfers.

[0027] Specifically, the inlet and outlet are designed to allow agricultural products that need to be dried to be poured into the inner cylinder 8 in a flexible manner. After drying, the products are discharged through the outlet. The chamfers on both sides of the support leg 2 can reduce the frictional resistance between the support leg 2 and the base 3 slide groove, making the sliding process smoother, reducing the load pressure on the electric telescopic rod 4, and extending the life of mechanical parts.

[0028] The working principle of this utility model is as follows:

[0029] First, the motor 7 is started, which drives the turning mechanism to rotate clockwise through the transmission rod 16. Its semi-circular scraper 18 is attached to the inner wall of the inner cylinder 8, turning the material near the cylinder wall towards the center, breaking the piled-up state and dispersing the clumps. At the same time, the transmission rod 16 drives the drive gear 9 to rotate clockwise. Through the meshing with the driven gear 11 and the internal gear ring 12, the inner cylinder 8 is forced to rotate counterclockwise, forming a compound motion of high-speed stirring of the turning mechanism and low-speed rotation of the inner cylinder 8 in the opposite direction.

[0030] Secondly, the combined motion causes the material to be both thrown up and turned inside the cylinder, and to move around with the inner cylinder 8, thus avoiding local accumulation. The blower mechanism blows hot air from the outside of the inner cylinder 8 into the cylinder 360° through the air guide pipe 13, the air supply ring 15, the annularly arranged exhaust pipe 14, and the nozzles. The hot air penetrates the material layer through the ventilation holes. The material changes position continuously during the turning process, making full contact with the hot air and achieving uniform drying.

[0031] It is worth mentioning that the electric telescopic rod 4 extends and retracts periodically, causing the support leg 2 to slide along the base 3, so that the outer barrel 1 makes a small linear reciprocating motion, which shakes away the material that may be stuck in the gap between the inner barrel 8 and the turning mechanism, avoiding mechanical blockage. At the same time, the tilt angle of the equipment can be changed by adjusting the electric telescopic rod 4, which, together with the turning mechanism, enhances the material disturbance effect.

[0032] Finally, the material to be dried is poured into the inner cylinder 8 through the feed port at the top of the first side plate 5. After drying, the material is discharged from the discharge port at the bottom of the second side plate 6 by gravity. The movable groove of the base 3 can be connected to the collection container or subsequent processes. The support leg 2 and the base 3 are connected by the limit block and the sliding groove to achieve stable sliding. The chamfer design on both sides of the support leg 2 reduces frictional resistance and improves the smoothness of equipment operation and service life.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
