[0040] As Figures 1 to 7 , the utility model discloses a spread cooling machine, including cooling groove 1, plate chain conveyor 2, set up in the cooling groove 1 side door's cold air import 11, refrigeration air supply component 3, air extraction cover 4 and a plurality of louver 5.Cooling groove 1 at least upper opening, and plate chain conveyor 2 passes through from cooling groove 1;Cold air import 11 is located between the upper and lower plate chain of plate chain conveyor 2, and the width of plate chain is adapted with the width of cooling groove, to make the cooling space that forms between the upper and lower plate chain almost airtight;Refrigeration air supply component 3 is connected with cold air import 11;Air extraction cover 4 is covered in the upper of cooling groove 1;The louver 5 is set up in the side of air extraction cover 4.The plate chain in the drawing is only schematic, and other structural forms of plate chain have also been adopted.

[0041] As an embodiment of the utility model, refrigeration air supply component 3 includes surface cooler 31 and centrifugal fan 32 connected between surface cooler 31 and cold air import 11.Of course, refrigeration air supply component 3 can also adopt existing air conditioner and the like cooling component, and can realize the cold air of sending in.

[0042] When the air extraction amount in air extraction cover 4 is greater than the air intake amount, the negative pressure can easily appear in air extraction cover 4, once the negative pressure appears, the air flow is influenced, can cause the hot air in air extraction cover 4 to be unable to extract, thereby reducing the cooling effect on grain, therefore, in order to prevent the negative pressure, the air pressure detection device is installed in the air extraction cover 4 of the utility model, further, at least a part of louver 5 is the electric louver 5 of angle automatic regulation.Through detecting the air pressure in air extraction cover 4, the angle of louver 5 is manually or automatically adjusted, to adjust the air intake amount.

[0043] As Figures 1 to 4 , the end of the plate chain conveyor 2 is provided with a discharge hopper 6, and a brush assembly 7 is rotatably connected in the discharge hopper 6. As Figure 5 , the brush assembly 7 is in contact with the lower surface of the plate chain conveyor 2 and cleans it. The brush assembly 7 includes a brush and a driving device such as a motor for driving the brush to rotate. The brush is mainly used to clean the surface of the plate chain and the gap to ensure air circulation, and can also clean the grain adhered to the plate chain. The cleaned grain falls into the discharge hopper 6, reducing grain waste and preventing long-term leaving and mold.

[0044] As Figure 6 , the cooling tank 1 is provided with a plurality of partitions 12, and a separate air inlet area is formed between adjacent partitions 12. The air inlet area is provided one by one with the refrigeration air supply assembly 3. The partitions in the cooling tank 1 form a relatively independent space, and the blown cold air will not spread to both sides but will flow upwards, so that the cooling is more concentrated and the cooling effect is better. Further, the inside of the cold air inlet 11 is provided with a wind guide plate 15 for guiding the cold air upwards. The wind guide plate 15 guides the cold air upwards, so that it is blown out directly from the gap between the plate chains or directly cools the plate chains.

[0045] As Figure 6 and Figure 7 , the cooling tank 1 is also hinged with a cleaning door 13, and the cleaning door 13 is rotatably connected with a door bolt 14. The side wall of the cooling tank 1 is fixed with a lock groove 16 for clamping the door bolt. The cleaning door 13 can be quickly opened and closed, which is convenient for cleaning the grain falling from the upper plate chain to the lower plate chain.

[0046] The cooling tank 1 is also opened at the bottom, and the cooling tank 1 is provided with a water tray 8 for receiving water seepage from the plate chain and sewage from the cleaning equipment. Since the gap between the plate chains is small, the opening at the bottom of the cooling tank 1 will not cause too much leakage of the air inlet, and the separately provided water tray 8 can guide the seepage water out, preventing the seepage water from directly falling into the cooling tank 1 to increase the cleaning work or frequently opening the cleaning door 13 to clean the accumulated water in the cooling tank 1 to affect the cooling effect.

[0047] The plate chain conveyor 2 is inclined from the bottom to the top for conveying. The cooling machine of the present application can not only convey the steamed grain, but also cool the grain. The plate chain conveyor is conveyed from the bottom to the top, so that the next operation such as stacking can be performed after cooling is completed, saving process and space, thereby reducing cost.

[0048] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
