Description

Technical Field

[0001] This utility model relates to the technical field of grain feeding wheel structure, specifically to an insert-type grain feeding wheel and a dryer. Background Technology

[0002] Currently, the typical processing capacity of existing batch dryers is 20 to 30 tons. During the drying season, timely drying of grain is necessary, requiring frequent operation of the grain feeding rollers. However, most commercially available grain feeding rollers consist of multiple blades connected to a glass wheel shaft. This structure is not strong enough for drying large-tonnage grains and is prone to blade deformation, wear, and compression, increasing grain breakage during the drying process. Damage to the grain feeding roller necessitates machine downtime for repairs, consuming significant manpower and resources, increasing user costs, impacting dryer efficiency, and disrupting production.

[0003] In response to this situation, a six-section grain-distributing wheel has emerged on the market. This wheel consists of a six-sided cylinder fitted onto a roller, with the roller and the cylinder connected by a support beam. Distributing plates are mounted on the six-sided cylinder, and a first reinforcing rib is placed between the distributing plates and the cylinder. However, this six-section grain-distributing wheel is difficult to manufacture, requires numerous welding operations, and is prone to deformation during the welding process. Its internal hollow section is also too large, making the blades susceptible to deformation during grain distribution. Utility Model Content

[0031] like Figure 1 , Figure 2 As shown, this utility model discloses a blade-type grain-dispensing wheel, which includes a shaft tube 1, multiple first fixing plates 2, multiple second fixing plates 3, and multiple blades 4. The shaft tube 1 is a hollow shaft tube. The first fixing plates 2 are circular in shape to facilitate the rotation of the blade-type grain-dispensing wheel. The first fixing plate 2 has a first through hole 21 at its center, which is adapted to the shape of the shaft tube 1, thus facilitating the shaft tube 1 to pass through the first through hole 21. For example, the shaft tube 1 passes through the first through holes 21 of multiple first fixing plates 2, and the multiple first fixing plates 2 are arranged sequentially at intervals along the length direction of the shaft tube 1, wherein one first fixing plate 2 is located at one end of the shaft tube 1, and another first fixing plate 2 is located at the other end of the shaft tube 1. Optionally, the first fixing plates 2 are connected to the shaft tube 1 by welding.

[0032] like Figure 1 , Figure 3 , Figure 4 As shown, the second fixing plate 3 is circular in shape to facilitate the rotation of the insert-type grain-dispensing wheel. The second fixing plate 3 has a second through hole 32 at its center, which is adapted to the shape of the shaft tube 1, allowing the shaft tube 1 to pass through the second through hole 32. The shaft tube 1 passes through multiple second through holes 32 of the second fixing plates 3. Multiple second fixing plates 3 are all disposed on the shaft tube 1, and are respectively disposed between multiple first fixing plates 2, that is, multiple second fixing plates 3 are disposed between two adjacent first fixing plates 2. The multiple second fixing plates 3 located between two adjacent first fixing plates 2 are sequentially spaced along the length direction of the shaft tube 1. The second fixing plate 3 also has multiple positioning holes 31, the shape of which is adapted to the cross-sectional shape of the blade 4. The multiple positioning holes 31 are evenly distributed around the second through holes 32 of the second fixing plate 3, and all of the positioning holes 31 communicate with the second through holes 32. Optionally, the second fixing plate 3 and the shaft tube 1 are connected by welding.

[0033] like Figure 1 , Figure 4 As shown, multiple blades 4 are disposed on the outer surface of the shaft tube 1, and the multiple blades 4 are evenly distributed around the axis of the shaft tube 1. One side of each blade 4 along its length is connected to the outer surface of the shaft tube 1. As shown in the figure, the cross-sectional shape of the blade 4 is L-shaped, and the blade 4 includes a first sub-blade 42 and a second sub-blade 43. The connection between the first sub-blade 42 and the second sub-blade 43 is the bend of the blade 4, and a rounded corner 44 is provided at the bend of the blade 4. The distance from the bend to the connection between the blade 4 and the shaft tube 1 is greater than the distance from the bend to the other end of the blade 4. Figure 4 This is a cross-sectional view of a blade-type grain reel. Figure 4 In this design, the first sub-blade 42 is longer than the second sub-blade 43. The blade 4 passes through the positioning hole 31 of the second fixing plate 3 and is connected to the shaft tube 1. Simultaneously, both ends of the blade 4 along its length are connected to a first fixing plate 2. Optionally, the blade 4 is connected to the shaft tube 1 by welding.

[0034] Compared with existing technologies, the blades 4 of the insert-type grain feeding wheel of this utility model do not overlap. The blades 4 are fixed by the first fixing plate 2, and the blades 4 pass through the positioning holes 31 of the second fixing plate 3. This increases the overall rigidity of the insert-type grain feeding wheel, reduces the risk of blade deformation, and improves the reliability of the dryer. Welding positioning is also possible, reducing the difficulty of positioning the blades 4, improving the precision in the grain feeding wheel manufacturing process, reducing manufacturing difficulty, and increasing production efficiency.

[0035] Optional, such as Figure 1 As shown, the shaft tube 1 has shaft heads 5 at both ends along its length. Specifically, both ends of the shaft tube 1 have pin holes, and the shaft head 5 also has a pin hole. A locating pin passes through the pin hole of the shaft head 5 and the pin hole of the shaft tube 1, so that the shaft head 5 is connected to the shaft tube 1.

[0036] Assembly process of an exemplary embodiment:

[0037] like Figures 1 to 4As shown, a first fixing plate 2 is fitted onto the shaft tube 1, positioned at the center of the shaft tube 1, and then welded to the shaft tube 1. Multiple second fixing plates 3 are fitted onto the shaft tube 1, located on either side of the first fixing plate 2, and evenly spaced along the axis of the shaft tube 1. The multiple second fixing plates 3 are then welded to the shaft tube 1. Multiple blades 4 are provided on both sides of the first fixing plate 2 located in the center of the shaft tube 1; therefore, the structure of one side is described as an example. Multiple blades 4 are provided on one side of the first fixing plate 2 located in the center of the shaft tube 1. The positioning holes 31 of the multiple second fixing plates 3 are aligned one-to-one, with one blade 4 positioned in each positioning hole 31. One end of the blade 4 passes through the positioning holes 31 of the multiple second fixing plates 3 sequentially, and the positioning holes 31 serve to fix and limit the blade 4. The blades 4 are then welded to the shaft tube 1, and simultaneously welded to the second fixing plates 3. A first fixing plate 2 is provided at each end of the shaft tube 1, that is, each end of the blade 4 abuts against a first fixing plate 2, and each end of the blade 4 is welded to a first fixing plate 2. Finally, a shaft head 5 is provided at each end of the shaft tube 1.

[0038] In the manufacturing process of the insert-type grain-dispatching wheel of this utility model, there is no overlap or welding between the blades 4, which reduces the risk of thermal deformation during welding and improves the strength and rigidity of the insert-type grain-dispatching wheel. When installed on a dryer, the insert-type grain-dispatching wheel of this utility model is not easily deformed, reducing the grain breakage rate and reducing machine maintenance costs.

[0039] This utility model discloses a dryer, including the above-described insert-type grain feeding wheel, which is mounted on the dryer, and the dryer can be a grain dryer.
