Description

Technical Field

[0001] The utility model relates to the field of drying, in particular to a circulating transportation mechanism and a continuous dryer thereof. Background Art

[0002] With the large-scale development of the economic agricultural product industry, the yield of cash crops has also increased significantly. The production process of agricultural products covers multiple links such as planting, maintenance, picking, processing, packaging and sales. In the processing stage, most crops need to be dehydrated. At present, common dehydration methods include sun drying, natural air drying, hot air drying equipment and freeze drying, etc.; however, traditional sun drying and natural air drying methods are greatly affected by climate and site conditions and are not very suitable for large-scale production; in contrast, hot air drying equipment has the advantages of small floor area, strong processing capacity and not being restricted by climate conditions, so it has been widely used in agricultural production; for different types of materials, the hot air drying equipment also has corresponding designs; for example, for materials that cannot be turned over, the mainly used in the market is a box-type drying room; this drying room and the hot air device are of a fixed structure, and the internal material rack is designed to be pushable. Usually, the material rack can accommodate 10 to 15 layers of materials. After being manually loaded into the tray and placed on the material rack, it is then pushed into the drying room for drying; in order to ensure the uniformity of material drying, manual turning and changing the position of the material tray are required during the drying process; however, the box-type drying room and the material rack drying equipment have some deficiencies in actual application:

[0003] 1. The structure of the material rack is compact, although it improves the space utilization rate, but due to the large number of material trays, the height difference of the material trays is relatively large; this makes it difficult to manually load the trays and push the material rack, especially when dealing with materials with higher water content, the operation becomes more inconvenient due to the increased weight of the rack body.

[0004] 2. Due to the large number and density of material layers, the circulation of hot air in the drying room is restricted; this results in the fast drying speed of the materials near the air outlet, while the materials far from the air outlet or blocked may not be fully dried; therefore, there are differences in the drying degree of the whole batch of materials.

[0005] 3. To solve the above problems, in actual operation, the method of regularly pushing out the material rack and changing the material tray is often used to improve the drying effect; although this can improve the uniformity of material drying, it also increases heat loss and labor costs.

The trays move in the drying box body along with the chains, from the inlet to the outlet. A lifting mechanism is also designed to ensure that the trays do not tilt during the rising process. Each tray of materials passes through the same drying path, increasing the uniformity of material drying and keeping the direction of the materials always upward and unchanged. At the same time, the trays will not turn over during operation, which is suitable for materials that cannot be turned over. In addition, the device is also equipped with a guiding mechanism device to ensure the stability of the materials in the trays. Currently, the continuous dryers existing in the market include mesh - belt type, flip - plate type, hanging - basket type, etc. These devices will turn the materials during the drying process.

[0035] It should be understood that the term " / " used herein is generally used to indicate that the associated objects before and after are in an "or" relationship. For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone.

[0036] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for the sake of description, the structures, ratios, sizes, etc. shown in the drawings are only used to cooperate with the content disclosed in the specification for those skilled in this technology to understand and read, and are not used to limit the conditions for the present application to be implemented. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present application. Technologies, methods, and devices known to those of ordinary skill in the relevant field may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: Similar reference numerals and letters denote similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0037] In the description of the present application, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description. Without contrary description, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be understood as limiting the protection scope of the present application; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

The right end of the material dragging member 4 contacts the guiding movable member 33 and then continues to be lifted. The material dragging member 4 pushes the guiding movable member 33 open. When the left end of the material dragging member 4 rotates upward to the left along with the driven traction chain 123 and reaches the top, the guiding movable member 33 returns to its original state. At the same time, the right end of the material dragging member 4 immediately disengages from the lifting traction auxiliary member 2231 on the lifting traction chain 223. Then, the movable mechanism 42 at the right end of the material dragging member 4 reaches the guiding flat member 31 through the upper surface of the guiding movable member 33. The material dragging member 4 returns to the position in the standby state. This process is one cycle of the material dragging member 4. In the operation process of a continuous dryer, a plurality of material dragging members 4 can be arranged to continuously transport and dry materials in an uninterrupted cycle on the driven traction chain 123.
