Description

Technical Field

[0001] This utility model relates to the technical field of grain drying equipment, and in particular to a grain dryer's dispersing mechanism. Background Technology

[0002] Grain requires drying during the harvest season, and even more so during rainy weather, rapid drying is necessary before storage. Existing grain dryers use hot air blown into the main unit for rapid drying, such as the high-efficiency grain drying box disclosed in patent document CN112129067A and the multi-layer flat-lay dispersed drying mechanism and drying process for vegetables disclosed in CN114812116A. Both are equipped with a dispersing mechanism to disperse the grain particles and increase the contact area with hot air, thereby improving drying efficiency. However, in actual production, moist grain has lower hardness, and the blades in the dispersing mechanism can break the grain. How to dry grain quickly and efficiently without breaking the grain particles is a pressing problem that needs to be solved.

[0003] A grain dryer dispersing mechanism is proposed to solve the above problems. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a grain dryer dispersing mechanism, which effectively solves the problem that the dispersing mechanism in the existing grain dryer is prone to causing grain particle breakage.

[0005] The technical solution includes a conical outer shell with a feed inlet. The upper sidewall of the outer shell has a rotating cylinder, and the lower end of the cylinder has a downward-opening conical section. Multiple raised strips are evenly distributed circumferentially on the conical surface of the conical section. An annular plate is fixed to the inner sidewall of the outer shell, with its outer and inner walls fitting together. The lower end of the annular plate contracts inward and then tilts upward. A spiral guide vane is located on the inner sidewall of the annular plate, and multiple air inlets are provided on its sidewall. The lower edge of the conical section is located within the annular cavity. When the grain is dispersed and falls along the raised strips on the conical section, the hot air from the air inlets blows the grain particles apart along with the spiral guide vane.

[0006] Preferably, the air inlet opening is tilted downwards, and multiple air inlets are evenly distributed around the circumference, with the air inlets connected to the hot air blower.

[0007] Preferably, the raised strip is spiral-shaped.

[0008] Preferably, the upper end of the cylinder extends out of the outer shell, and a motor is installed on the outer shell. The motor is driven by the upper end of the outer shell via a pulley.

[0009] This invention has a clever structure that uses wind power and spiral guide plates to break up the grain, while also ensuring that the grain particles are not broken as much as possible. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 7 The present invention includes a conical outer shell 1, a feed inlet 2 on the outer shell 1, a rotating cylinder 3 on the upper side wall of the outer shell 1, a downward-opening conical cylinder 4 at the lower end of the cylinder 3, and multiple raised strips 5 evenly distributed circumferentially on the conical surface of the conical cylinder 4; an annular plate 6 is fixed on the inner side wall of the outer shell 1, the outer side wall and the inner side wall of the annular plate 6 are in contact, the lower end of the annular plate 6 contracts inward and then tilts upward, a spiral guide plate 7 is provided on the inner side wall of the annular plate 6, and multiple air inlets 8 are provided on the side wall of the annular plate 6; the lower edge of the conical cylinder 4 is located inside the annular cylinder cavity, when the grain is dispersed and falls along the multiple raised strips 5 on the conical cylinder 4, the hot air from the air inlets 8 blows the grain particles apart along with the spiral guide plate 7.

[0019] In order to enable the grain particles to move along the lower side of the annular plate 6 and the spiral guide plate 7 on it, the air inlet 8 is inclined downward and multiple air inlets 8 are evenly distributed around the circumference. The air inlets 8 are connected to the hot air blower.

[0020] To ensure more uniform grain distribution, the raised strips 5 are spiral-shaped.

[0021] In order to enable the cylinder 3 to rotate actively, the upper end of the cylinder 3 extends out of the outer shell 1, and a motor is installed on the outer shell 1. The motor and the upper end of the outer shell 1 are driven by a pulley.

[0022] It is worth noting that a bearing is connected between the cylinder 3 and the upper side wall of the outer shell 1, so that the grain in the feed inlet 2 can fall directly onto the conical cylinder 4.

[0023] During operation, the motor starts, driving the cylinder 3 to rotate via the pulley. The cylinder 3 then rotates the conical cylinder 4 at its lower end. Grain enters through the feed inlet 2 and falls onto the rotating conical cylinder 4. The raised strips 5 on the conical cylinder initially disperse the grain. After falling from the lower edge of the conical cylinder 4, the grain is tilted downwards by the airflow from the air inlet. This causes the grain particles to move inwards along the lower end of the annular plate 6 and the spiral guide plate 7. Because the lower end of the annular plate 6 is inwardly contracted and upwardly inclined, the grain particles tend to move upwards under the influence of the airflow. Finally, the grain particles collide with the inner surface of the conical cylinder 4 and fall down, eventually exiting through the lower end of the outer shell 1. Moisture is discharged from the upper end of the cylinder 3 through the outer shell 1 with the hot air, thus achieving drying. This process is repeated multiple times until the grain reaches the required drying temperature.

[0024] This invention has a clever structure. By dispersing the grain twice, it can fully expose the grain to the air, increase the contact area between the grain and the hot air, and disperse the grain through wind and spiral guide plate 7, while also ensuring that the grain grain does not break as much as possible.
