Technical Field

[0001] This utility model relates to the field of dryer conveying technology, and in particular to a conveying structure for an agricultural product dryer. Background Technology

[0002] Agricultural product dryers are equipment specifically designed for drying agricultural products in agricultural production. They are widely used in the drying process of grains, fruits and vegetables, medicinal herbs, tea, and other agricultural products. With the continuous development of modern agriculture, traditional natural sun-drying and artificial drying methods are no longer sufficient to meet the needs of large-scale production. As a highly efficient and energy-saving technology, dryers can effectively remove moisture from agricultural products in a short time, ensuring product quality and extending their shelf life.

[0003] In agricultural product dryers, the conveying mechanism is a crucial component. It is responsible for transferring the agricultural products to be dried from one location to another, ensuring that the materials are heated and processed evenly inside the dryer. When using the existing agricultural product dryer conveying structure, it is impossible to separate two different agricultural products during the drying process. As a result, the subsequent separation work requires a lot of extra time, thereby reducing the working performance of the dryer.

[0004] Therefore, there is an urgent need to provide a conveying structure for agricultural product dryers to solve the above problems. Utility Model Content

[0007] The inner and outer conveying cylinders are equipped with conveying mechanisms near the center to ensure that the two crops are discharged in the same direction, making it easier to collect and distinguish them.

[0008] The present invention is further configured such that: the double-layer drive mechanism includes a drive shaft disposed inside the inner layer conveying cylinder, and one end of the drive shaft is provided with a first support frame supporting the inner layer conveying cylinder, and the other end of the first support frame is supported with a drive cylinder fixed to the inner layer conveying cylinder, so as to ensure the rotation of the inner layer conveying cylinder.

[0009] The present invention is further configured such that: a second support frame for supporting the outer conveying cylinder is provided at one end of the drive shaft away from the corresponding first support frame.

[0010] The present invention is further configured such that: the drive cylinder is provided with a W-shaped drive groove, one end of the drive shaft is provided with a support rod and a sliding groove opened thereon between the first support frame and the second support frame, and a limiting drive column with one end located in the drive groove slides on the sliding groove, and the other end of the drive column is located on a track fixed on the outer layer conveying cylinder, for driving the inner layer conveying cylinder and the outer layer conveying cylinder to rotate in opposite directions.

[0011] The present invention is further configured such that: a connecting sleeve is provided on the side of the support rod facing away from the inner conveying cylinder and is sleeved on the drive shaft, and the connecting sleeve is fixed to the dryer to ensure the stability of the support rod.

[0012] The present invention is further configured such that: the material conveying mechanism includes a first threaded plate embedded in the segmented inner conveying cylinder and a second threaded plate embedded in the segmented outer conveying cylinder, and the first threaded plate and the second threaded plate are arranged in opposite spiral configurations.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] Please see Figures 1-4 A conveying structure for an agricultural product dryer includes an inner conveying cylinder 12 and an outer conveying cylinder 11 sleeved on the outside. A double-layer drive mechanism 2 is provided between the inner conveying cylinder 12 and the outer conveying cylinder 11 to drive the inner conveying cylinder 12 and the outer conveying cylinder 11 to rotate in opposite directions, so as to achieve different degrees of drying according to different crops. A material conveying mechanism 3 is provided near the center of the inner conveying cylinder 12 and the outer conveying cylinder 11 to ensure that the two kinds of crops are discharged in the same direction, so as to facilitate better collection and differentiation.

[0023] like Figures 3-4 As shown, the double-layer drive mechanism 2 includes a drive shaft 21 internally disposed in the inner layer conveying cylinder 12. One end of the drive shaft 21 is provided with a first support frame 23 supporting the inner layer conveying cylinder 12, and the other end of the first support frame 23 supports a drive cylinder 24 fixed to the inner layer conveying cylinder 12 to ensure the rotation of the inner layer conveying cylinder 12. The end of the drive shaft 21 away from the corresponding first support frame 23 is provided with a second support frame 210 for supporting the outer layer conveying cylinder 11. The drive cylinder 24 is provided with a W-shaped drive groove 25. One end of the drive shaft 21 is located at the first... A support rod 27 and a slide groove 28 are provided between a support frame 23 and a second support frame 210. A limiting drive column 29 with one end located in the drive groove 25 slides on the slide groove 28. The other end of the drive column 29 is located on the track 26 fixed on the outer conveyor cylinder 11, which is used to drive the inner conveyor cylinder 12 and the outer conveyor cylinder 11 to rotate in opposite directions. A connecting sleeve 22 is provided on the side of the support rod 27 away from the inner conveyor cylinder 12 and is sleeved on the drive shaft 21. The connecting sleeve 22 is fixed to the dryer to ensure the stability of the support rod 27.

[0024] The drive shaft 21 is connected to the existing drive motor of the dryer. The drive motor drives the drive shaft 21 to rotate, which in turn causes the drive cylinder 24 and the inner conveyor cylinder 12 on the first support frame 23 to rotate. The crops located in the inner layer are then rotated and dried. When the drive cylinder 24 starts to rotate, it will drive the drive column 29 on the drive groove 25 to move along the slide groove 28 on the support rod 27. Since the track 26 is in an arc-shaped asymmetrical twisted shape, and the drive column 29 is at one end of the drive groove 25 and at the top of the track 26, the movement of the drive column 29 will compress the track 26 to achieve rotation. Therefore, with the W-shaped drive groove 25 and the arc-shaped twisted track 26, the inner conveyor cylinder 12 and the outer conveyor cylinder 11 rotate in opposite directions, thereby conveying the crops.

[0025] The inner conveyor cylinder 12 conveys the initial agricultural products with higher moisture content, while the outer conveyor cylinder 11 conveys the initial agricultural products with lower moisture content. The two spirals rotate in opposite directions, allowing hot airflow to penetrate both layers of material simultaneously through the ventilation holes. This avoids the problem of over-drying of the upper layer and under-drying of the lower layer in traditional single-layer conveying, while also ensuring that the two types of crops can be collected separately.

[0026] like Figure 4 As shown, the material conveying mechanism 3 includes a segmented first threaded plate 31 embedded in the inner conveying cylinder 12 and a segmented second threaded plate 32 embedded in the outer conveying cylinder 11, and the first threaded plate 31 and the second threaded plate 32 are arranged in opposite spiral configurations.

[0027] When the inner conveying cylinder 12 and the outer conveying cylinder 11 are in reverse, in order to better collect them at the same discharge end, the first threaded plate 31 and the second threaded plate 32 need to be set in opposite spirals. The two rotate in opposite directions and have opposite rotation directions. However, through the reverse matching of rotation direction and direction, the same side feeding and same direction conveying are finally achieved. Moreover, because the rotation is opposite, the airflow disturbance generated by the movement of materials in the inner and outer cylinders is more uniform, which improves the drying efficiency.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
