DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.
[0026] refer to Figure 1-Figure 3 The utility model discloses a drying device, including a drying box 1, wherein a feed port 2 is arranged on the top of the drying box 1, a loading elevator 3 is arranged along one side of the drying box 1, and a horizontally rotating swing arm material distributor 4 is arranged between the loading elevator 3 and the feed port 2. During the horizontal rotation of the swing arm material distributor 4, the unloading end of the swing arm material distributor 4 is always located above the feed port 2. It should be noted that: as a preferred solution, the loading elevator 3 is arranged side by side along the length direction of the drying box, or along one side of the drying box, so as to effectively save floor space. The loading elevator 3 is a climbing conveyor belt, which transports the material from the ground to the top of the drying box, and enters the drying box through the feed port. The setting of the swing arm material distributor can effectively avoid the problem of material accumulation, so that the material is evenly distributed in the drying box and on the conveyor belt located on the top layer. Based on this, the feed port is preferably rectangular, and the swing arm feeder is located in the middle of the length direction of the feed port. By controlling the left and right swing angle of the swing arm feeder, the material on the swing arm feeder falls along the feed port into the drying box.
[0027] Furthermore, in order to facilitate the placement of materials on the loading elevator, the loading elevator (climbing conveyor belt) is divided into a straight section and a slope section. A pit is dug on the ground to accommodate the straight section conveyor belt, and the straight section conveyor belt is placed in the pit. The material can be directly poured from the ground onto the straight section conveyor belt, and then the slope section conveyor belt transports the material to the top of the drying box, and the swing arm distributor 4 evenly distributes the material to the drying box.
[0028] Furthermore, a fixed platform 5 is provided on the top of the drying box 1, and the bottom of one end of the swing arm feeder 4 is rotatably provided on the fixed platform 5 through a rotating shaft 6, and the other end is located above the feed port 2, and a motor 7 is provided at the bottom of the swing arm feeder 4, near the rotating shaft 6. It should be noted that both ends of the rotating shaft are fixed to the swing arm feeder and the fixed platform through bearings, so that the swing arm feeder can rotate freely. The motor is arranged at a position close to the rotating shaft to avoid a large change in the position of the feeding end of the swing arm feeder, so that the material cannot all fall onto the swing arm feeder, and some of the material falls to the top of the drying box. The motor used in this embodiment can be selected as a servo motor to accurately control the speed and position of the swing arm feeder.
[0029] Furthermore, a universal wheel 8 is provided at the bottom of the swing arm material distributor 4, between the feed port 2 and the motor 7. The setting of the universal wheel not only supports the swing arm material distributor, but also assists the swing arm material distributor to move more smoothly. When setting, the universal wheel can contact the top of the drying box or the fixed platform, and can be set as needed.
[0030] Furthermore, a transport conveyor 9 is provided on the top of the drying box 1, and the unloading end of the loading elevator 3 is located above the transport conveyor 9. A lifting conveyor 10 is provided at the unloading end of the transport conveyor 9, and the unloading end of the lifting conveyor 10 is located above the swing arm material distributor 4. The transport conveyor 9 is provided with an automatic metering device and a moisture content detection device 11, and the moisture content detection device 11 is provided at the loading end of the transport conveyor 9 and below the unloading end of the loading elevator 3. It should be noted that the moisture content detection device and the automatic metering device are both existing equipment. As one embodiment, the two ends of the transport conveyor are respectively arranged vertically with the loading elevator and the lifting conveyor. The lifting conveyor is the same as the loading elevator, and both are climbing conveyor belts, which are divided into a straight section and a slope section. The unloading end of the transport conveyor is located above the lifting conveyor, and the material transported by the transport conveyor falls directly onto the straight section conveyor belt of the transport conveyor, and then is transported to the swing arm material distributor by the slope section conveyor belt.
[0031] Furthermore, a first discharge conveyor 12 is provided below the discharge port 15 of the drying box 1, and a second discharge conveyor 13 is provided at the unloading end of the first discharge conveyor 12, and the unloading end of the first discharge conveyor 12 is located above the second discharge conveyor 13. It should be noted that the discharge port of the drying box is arranged along the drying box, preferably in a rectangular shape, to increase the discharge amount. The first discharge conveyor and the second discharge conveyor are arranged vertically in space, and the second discharge conveyor is a climbing conveyor belt, which is divided into a straight section and a slope section. The unloading end of the first discharge conveyor is located above the straight section conveyor belt of the second discharge conveyor, and the slope section is at a certain height from the ground, which is convenient for loading or bagging.
[0032] Furthermore, in order to realize cyclic drying, the feeding end of the first discharge conveyor 12 is located above the feeding elevator 3, that is, above the straight section of the feeding elevator. A fan 16 is provided near the feeding end of the first discharge conveyor 12 to blow away dust and impurities (leaves, etc.). When the drying box is full of materials, the feeding elevator stops feeding. After the first drying is completed, the first discharge conveyor rotates forward to transport the materials to the feeding elevator for cyclic processing; after processing, the first discharge conveyor reverses to transport the finished materials to the second discharge conveyor to complete the discharge of the finished materials.
[0033] Furthermore, the unloading ends of the loading elevator 3, the lifting conveyor 10 and the second unloading conveyor 13 are all provided with guide grooves 14 to prevent materials from spilling. The conveyor belts of the loading elevator 3, the swing arm material spreading machine 4, the transport conveyor 9, the lifting conveyor 10, the first unloading conveyor 12 and the second unloading conveyor 13 disclosed in the utility model are all provided with protrusions to prevent materials from rolling on the conveyor belt or falling from the conveyor belt.
[0034] Furthermore, in order to increase the drying efficiency, a multi-layer conveyor belt is provided in the drying box 1 to realize S-shaped feeding. The heating equipment, air intake equipment, exhaust equipment, etc. provided in the drying box can be installed using existing equipment.
[0035] As one embodiment, the conveyor belt is arranged horizontally, and the unloading end of each layer of the conveyor belt is provided with a guide plate inclined toward the conveyor belt of the next layer, and the conveyor belt at the bottom layer corresponds to the discharge port 15 of the drying box 1. It should be noted that the guide plate is arranged separately from the conveyor belt of the layer, so that the material transported by the conveyor belt directly falls onto the guide plate through its unloading end, and then falls into the loading end of the conveyor belt of the next layer through the guide plate. In this embodiment, the multiple layers of conveyor belts are arranged neatly, that is, the two ends are flush.
[0036] As another embodiment, the conveyor belt is horizontally and staggered, that is, the two ends of the multi-layer conveyor belts are not aligned but staggered, and the unloading end of each layer of the conveyor belt corresponds to the conveyor belt of the next layer, that is, the unloading end of the conveyor belt of the previous layer corresponds to the loading end of the conveyor belt of the next layer. This setting method does not require the setting of a guide plate, and the conveyor belt located at the bottom layer corresponds to the discharge port 15 of the drying box 1.
[0037] As another embodiment, the conveyor belt is arranged obliquely, each layer of the conveyor belt is inclined toward the conveyor belt of the next layer, and the unloading end corresponds to the conveyor belt of the next layer, that is, the conveyor belt of the previous layer is arranged obliquely toward the conveyor belt of the next layer, and the conveyor belt at the bottom layer corresponds to the discharge port 15 of the drying box 1. The arrangement of the conveyor belt in the drying box can be set according to the needs (type and characteristics of the material, etc.).
[0038] When using the utility model, the material is loaded at the loading port, and the material is lifted from the side of the drying box to the top of the drying box by the loading elevator, and then enters the transport conveyor. After the weight and moisture content of the material are measured by the automatic metering equipment and moisture content detection equipment, the material enters the lifting conveyor, and then transported to the swing arm material spreading machine to evenly spread the material in the drying box for drying (processing). After the material is dried, it runs to the discharge port and enters the first discharge conveyor. The first discharge conveyor rotates forward to transport the material to the loading elevator for cyclic processing; when the material is processed, the first discharge conveyor reverses to transport the finished material to the second discharge conveyor, and is directly loaded or bagged at the discharge port (or exit) of the second discharge conveyor.
