Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] A ventilation mechanism for refrigerating agricultural products, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a base 1, a chassis 2, a ventilation duct 3, a servo motor 4, a first fan 5, a cooling box 6, a third fan 8, a filter 11, and a cleaning assembly 9. The chassis 2 is mounted on the base 1 and serves as the mounting point. A ventilation duct 3 is installed on the top of the chassis 2, allowing airflow exchange. The servo motor 4 is installed inside the chassis 2, driving the first fan 5. The output shaft of the servo motor 4 is connected to the first fan 5 via a coupling, enabling the first fan 5 to rotate. A cooling box 6 is installed inside the chassis 2, generating a large amount of cold air. A third fan 8 is installed at the end of the ventilation duct 3 furthest from the chassis 2, and its rotation allows air to be cooled. Cold air is delivered into the refrigeration unit to lower the temperature inside, thus maintaining a suitable temperature environment. A filter screen 11 is embedded at the end of the ventilation duct 3 near the third fan 8. The filter screen 11 serves to filter and prevent larger impurities from entering the ventilation mechanism and affecting its performance. A cleaning component 9 for cleaning the filter screen 11 is provided at the end of the ventilation duct 3 away from the casing 2. The cleaning component 9 includes a sponge block 96 and a first connecting block 95. The sponge block 96 is mounted on the first connecting block 95 and is in close contact with the filter screen 11. The drive motor 90 in the cleaning component 9 can drive the screw 91 to rotate, causing the sponge block 96 and the brush 97 to move up and down to clean the dust on the filter screen 11.

[0024] like Figure 4 and Figure 5As shown, the cleaning assembly 9 also includes a drive motor 90, a screw 91, a bracket 92, a guide rod 93, and a sliding block 94. The drive motor 90 is installed on the left side of the ventilation pipe 3, and the drive motor 90 drives the pipe. The screw 91 is installed on the left side of the ventilation pipe 3, and the screw 91 can rotate on the left side of the ventilation pipe 3. The guide rod 93 is provided on the right side of the ventilation pipe 3, and the guide rod 93 provides guidance. The output shaft of the drive motor 90 is connected to the screw 91 through a coupling, and the output shaft of the drive motor 90 can drive the screw 91 to rotate through the coupling. A sliding block 94 is connected to the screw 91, and the sliding block 94 can move along the thread on the screw 91. The right end of the sliding block 94 is slidably connected to the guide rod 93. Four brackets 92 are provided at the front end of the ventilation duct 3. The brackets 92 support the installation. Guide rods 93 are installed on the brackets 92 at the positions corresponding to the screws 91. Sliding blocks 94 are installed on the guide rods 93. The sliding blocks 94 can slide on the guide rods 93. A first connecting block 95 is connected to the sliding blocks 94. The first connecting block 95 connects the two blocks. The rotation of the screws 91 can drive the sliding blocks 94 and the first connecting block 95 to move up and down. The sponge block 96 is attached to the first connecting block 95. The sponge block 96 cleans the filter screen 11 by moving the sponge block 96 up and down through the first connecting block 95.

[0025] When ventilation is required, servo motor 4 is activated. The output shaft of servo motor 4 drives the first fan 5 to rotate via a coupling. Simultaneously, the refrigeration unit 6 and the third fan 8 are activated. The rotation of the first fan 5 generates a large amount of cold air from the refrigeration unit 6, which is then delivered to the ventilation duct 3 and then to the third fan 8. The rotation of the third fan 8 delivers the cold air into the refrigeration unit, thereby lowering the temperature inside the refrigeration unit and maintaining a comfortable temperature environment. At the same time, the action of the first fan 5 and the third fan 8 creates negative pressure inside the refrigeration unit, expelling exhaust gases and harmful substances. The material is discharged, thus completing the ventilation and air exchange work in the refrigeration unit. When it is necessary to clean the filter screen 11, the drive motor 90 is started. The output shaft of the drive motor 90 drives the screw 91 to rotate through the coupling. The rotation of the screw 91 drives the sliding block 94 and the first connecting block 95 connected to it to move one end along the thread, and the other end slides on the guide rod 93 with the sliding block 94, so that the first connecting block 95 can move up and down, driving the sponge block 96 and brush 97 on the first connecting block 95 to clean the filter screen 11, thus completing the cleaning work of the filter screen 11.

[0026] Example 2

[0027] Based on Example 1, such as Figure 6 and Figure 7As shown, it also includes a collection component 10 for collecting condensate. The collection component 10 is provided at the bottom of the ventilation pipe 3. The collection component 10 includes a mounting plate 100, a second connecting block 101, a collection frame 102, and a mounting block 103. The mounting plate 100 is installed at the bottom left end of the ventilation pipe 3. The mounting plate 100 serves as the mounting plate. The second connecting block 101 is provided on the mounting plate 100. The second connecting block 101 serves as the connecting block. The collection frame 102 is installed on the second connecting block 101 through the mounting block 103. The collection frame 102 is installed in a movable manner, which makes it easy for workers to remove the collection frame 102 and clean up the condensate and debris that falls during cleaning.

[0028] like Figure 1 and Figure 5 As shown, it also includes a brush 97, a second fan 7, and a rubber pad 12. The brush 97 is located at the lower part of the first connecting block 95. The brush 97 is used for cleaning. When cleaning the filter screen 11, the brush 97 moves up and down through the first connecting block 95 to clean the filter screen 11 better. The second fan 7 is installed on the top of the refrigeration box 6. The rotation of the second fan 7 can accelerate the air circulation in the ventilation duct 3. The bottom of the base 1 is provided with a rubber pad 12. The rubber pad 12 is used for anti-slip to prevent the ventilation mechanism from sliding and falling during ventilation and causing damage. The front end of the casing 2 is provided with a filter screen 11. The filter screen 11 can intercept larger external impurities from entering the ventilation mechanism and avoid affecting its working performance.

[0029] When it is necessary to clean up the fallen condensate, the collection frame 102 installed at the bottom of the ventilation pipe 3 away from the chassis 2 can collect the generated condensate and the debris that falls during cleaning. By sliding 103 out of 101, 102 can be removed for easy disposal. When ventilation is in operation, the filter 11 installed at the end of the chassis 2 near the first fan 5 and the filter 11 installed at the end of the ventilation pipe 3 near the third fan 8 can prevent large impurities from entering the ventilation mechanism and affecting its performance. The rubber pad 12 installed at the bottom of the base 1 serves as an anti-slip pad to prevent the ventilation mechanism from sliding and falling during ventilation, which could cause damage. The brush 97 installed at the bottom of the first connecting block 95 serves a cleaning function, allowing for better cleaning of the filter 11.
