DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] The utility model discloses an air blowing device for a fruit sorting machine, which is mainly used for blowing dust from the surface of fruits.
[0025] Reference Figure 2 , Figure 3 and Figure 4 , a blowing device for a fruit sorting machine, comprising a connecting frame 1, an adjusting mechanism 4 for adjusting the size of the air flow derived from the square blowing nozzle 3; the adjusting mechanism 4 comprises a fixing plate 401 fixedly connected to the front side of the inside of the square blowing nozzle 3, the surface of the fixing plate 401 is provided with through holes 402 arranged at equal intervals, a partition 403 is slidably connected to the right side of the inside of the fixing plate 401, a connecting ring 404 is connected to the left side of the upper end of the partition 403, a screw rod 405 is connected to the bearing inside the connecting ring 404, a knob 408 is fixedly connected to the left side of the screw rod 405, the screw rod 405 is connected to the bearing of the square blowing nozzle 3, a first slide groove 406 is provided on the right side of the inside of the fixing plate 401, a second slide groove 407 is provided on the upper end of the fixing plate 401, and the partition 403 is connected to the knob 408 through the connecting ring 404 and the screw rod 405;
[0026] In the present embodiment, in the process of sorting soft-skinned fruits, such as soft peaches, the surface of the soft-skinned fruits is purged through the square blowing nozzle 3. Since the square blowing nozzle 3 has a large caliber, the gas directly purges the surface of the soft peaches, and the impact force of the airflow is too strong, which can easily damage the peach skin. Therefore, a fixing plate 401 is arranged inside the square blowing nozzle 3. After the gas passes through the multiple groups of through holes 402 on the fixing plate 401, it contacts the peach skin, blows away the dust on the surface of the peach and the surrounding leaves, and diverts the gas exported from the square blowing nozzle 3 through the multiple groups of through holes 402, thereby reducing the impact force of the overall gas blowing and preventing the skin of the soft-skinned fruits from being damaged. When the small fruits are sorted, For example, for dates, the large fruits are previously purged, and the relative blowing intensity cannot shake the displacement of the large fruits. During the transportation of small fruits, the same airflow size is likely to cause the position of the small fruits to shift. Therefore, the rotating knob 408 drives the transmission screw 405 to rotate, prompting the connecting ring 404 to move to the left along the second slide groove 407, and simultaneously drives the partition 403 to slide to the left along the first slide groove 406. The partition 403 moves to the left, blocks the through hole 402, reduces the airflow passing through, and the gas intensity blown out by the square blowing nozzle 3 decreases. At this time, after adjusting the blowing intensity corresponding to the small fruit, stop rotating the knob 408, and the surface of the small fruit and the surrounding leaves can be purged.
[0027] Reference Figure 1 and Figure 2In a preferred embodiment, a cylinder 2 is installed at the upper and lower ends of the left side of the connecting frame 1, a square blowing nozzle 3 is arranged at the front side of the cylinder 2, an air inlet 5 is arranged at the rear side of the cylinder 2, and an adjusting mechanism 4 is arranged inside the square blowing nozzle 3;
[0028] In this embodiment, when blowing dust on large fruits, such as durian, which is at a relatively high height, the upper and lower groups of cylinders 2 can simultaneously perform blowing actions to blow air on the surface of the durian to prevent the upper layer of the durian from being not blown away.
[0029] Reference Figure 1 In a preferred embodiment, the front side of the connecting frame 1 is connected to a supporting frame 6, the left and right ends of the supporting frame 6 are rotatably connected to rollers 7, a conveyor belt 9 is installed on the outer surface of the roller 7, and a motor 8 is connected to the front side of the left roller 7;
[0030] In this embodiment, the fruits picked from the orchard are placed on the conveyor belt 9, the motor 8 and the transmission roller 7 are started to drive the conveyor belt 9 to move, and the fruits on the conveyor belt 9 are transported from right to left and blown one by one through the square blowing nozzle 3.
[0031] Working principle: When in use, during the sorting process of soft-skinned fruits, such as soft peaches, the surface of the soft-skinned fruits is blown through the square blowing nozzle 3. Since the square blowing nozzle 3 has a large diameter, the gas directly blows the surface of the soft peaches, and the impact force of the air flow is too strong, which can easily damage the peach skin. Therefore, a fixing plate 401 is arranged inside the square blowing nozzle 3. After the gas passes through multiple groups of through holes 402 on the fixing plate 401, it contacts the peach skin, blows away the dust on the surface of the peach and the surrounding leaves, and diverts the gas exported from the square blowing nozzle 3 through the multiple groups of through holes 402, thereby reducing the impact force of the overall gas blowing and preventing the skin of the soft-skinned fruits from being damaged. When the small fruits are sorted, During the transportation process, such as dates, the large fruits are blown before, and the relative blowing intensity cannot shake the displacement of the large fruits. During the transportation of small fruits, the same airflow size is easy to cause the position of the small fruits to shift. Therefore, the rotating knob 408 drives the transmission screw 405 to rotate, prompting the connecting ring 404 to move to the left along the second slide groove 407, and simultaneously drives the partition 403 to slide to the left along the first slide groove 406. The partition 403 moves to the left, blocks the through hole 402, reduces the airflow passing through, and the gas intensity blown out by the square blowing nozzle 3 decreases. At this time, after adjusting the blowing intensity that the small fruit bears, stop rotating the knob 408, and the surface of the small fruit and the surrounding leaves can be blown.
