The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

As shown in FIG. 1 to FIG. 4 , the posture adjustment device 200 of the present application includes: a channel device 201 . The channel device 201 provides at least one fruit dropping channel 201a for the fruit to pass through when falling.

In order to make the damping medium enter the fruit-dropping channel 201a to exert damping effect on the fruit, the channel device 201 is further provided with a plurality of medium channels 201b arranged in layers. The fruit exerts a damping effect so that the fruit can change its falling posture under the damping effect when the channel device 201 falls.

As a specific solution, the damping medium contained in the medium channel 201b is liquid or/and gas. Generally, one medium can be used, but the damping effect can also be provided by mixing or alternating liquid and gas. Mixing means that a medium channel 201b simultaneously outputs a medium mixed with liquid and gas, such as a medium mixed with water and air. Only using water will cause damage to the appearance of the fruit, and using only gas may not be enough to provide damping. The way of alternation includes alternation in time and alternation in position. Specifically, the medium output from the medium channel 201b to the fruit-dropping channel 201a in a certain period of time is liquid, while the medium output from the medium channel 201b to the fruit-dropping channel 201a is gas in another period of time, in this way, the medium is alternated in a pulsed manner. The attitude adjustment of the fruit can be better achieved, but such a solution has higher requirements on the equipment for driving the medium and the valves of the pipeline, and the pipeline is easily damaged. As another "alternating" method, different medium channels 201b can be made to output different mediums, such as water and air, at "the same moment". As a specific solution, the medium channel 201b on the same height, or the medium channel 201b on the same layer (there may be a small height difference) can output the same medium, such as liquid, and then, the medium channel of another layer The output of 201b is another similar medium, such as gas. In this way, in different stages of the fruit's falling, the fruit will receive the damping brought by the same medium, and in the whole falling process, due to the alternating action of different damping media, the advantages of gas and liquid are combined, and the damping effect is effectively applied to the fruit.

As a specific solution, the extension direction of the medium channel 201b is set to intersect with the falling direction provided by the fruit drop channel 201a, and the extension direction of the medium channel 201b is set to converge toward the center of the fruit drop channel 201a. With such a solution, the extending direction of the medium channel 201b determines the direction in which the damping medium is output to the fruit-dropping channel 201a. The upwardly inclined medium channel 201b causes the output damping medium to exert at least two upward and central forces on the fruit. On the one hand, it prevents the fruit from falling too fast, and on the other hand, it makes the fruit tend to roll (not necessarily rolling), so that the fruit is not only decelerated by the damping medium when falling, but also corrected by the force of the damping medium in all directions. The falling posture is finally adjusted to the posture with the fruit stem facing up.

As a preferred solution, the angle β formed by the extending direction of the medium channel 201b and the falling direction provided by the channel space ranges from 40° to 60°, preferably 40° to 50°, and preferably 45°. In this way, the angle selection can better achieve the effect of posture adjustment.

As a specific solution, the technical idea of the present application can be realized by externally connecting a corresponding conduit to a cylindrical structure, but it is not easy to realize the overall assembly and production of the device.

As a preferred solution, as shown in FIG. 1 to FIG. 4 , the channel device 201 is integrated to form a fruit drop channel 201a and a medium channel 201b, and the channel device 201 is further provided with an interlayer space 201c to communicate with different medium channels 201b. The advantage of this is that the medium channel 201b of the channel device 201 does not need to externally connect many pipelines, and at the same time, the overall structure can withstand a relatively large pressure.

In order to enable the damping medium to act on the fruit more uniformly when it exits the fruit-dropping channel 201a, the cross-sectional shape of the medium channel 201b includes at least one curved edge, especially a circular arc edge.

As a further preferred solution, the channel shape of the medium channel 201b is set as a racetrack shape, and the channel shape here can be the shape of the final exit of the medium channel 201b, or the shape of any one or all cross-sections of the medium channel 201b. The use of the track type not only avoids the cross-sectional shape with slits or sharp corners (such as long rectangles), the medium flow has a high probability of cutting the fruit, while the direct use of the circular cross-section will make the damping effect not wide enough. The use of the racetrack shape ensures the effective area without producing obvious cutting action, and in combination with the distribution of the medium channels 201b, the damping effect can be better achieved.

As a further preferred solution, in order to adjust the posture of the fruit during the falling process, at the same time, the height of the channel device 201 is not too high (the fruit dropping channel 201a is too long), thereby causing the fruit to fall too much acceleration due to gravity. The ratio of the distance L4 of the two medium channels 201b in the falling direction to the length L3 of the fruit drop channel 201a ranges from 0.15 to 0.25, preferably from 0.18 to 0.22, and preferably from 0.2.

In order to ensure the flow rate of the damping medium and the structural strength of the channel device 201, the fruit drop channel 201a is constructed as a space of revolution with the central axis 201d as the axis. The ratio of the distance in radians θ is in the range of 0.3 to 0.4, preferably in the range of 0.35 to 0.38, and preferably in the range of 0.375.

The distance L4 of the medium channel 201b in the falling direction ranges from 90 mm to 120 mm, preferably ranges from 95 mm to 115 mm, and preferably ranges from 100 mm.

The radian spacing θ of the medium channel 201b in the circumferential direction is in the range of 60° to 80°, preferably in the range of 70° to 75°, and preferably in the range of 72°

The cross-sectional area of the medium channel 201b ranges from 400 cm ³ to 600 cm ³ , preferably ranges from 500 ³ to 550 ³ , and preferably ranges from 531 ³ .

The advantage of ensuring the above size design is also to ensure that the damping medium produces a damping arc range in the circumferential direction.

As a more specific solution, the channel device is further provided with a medium source interface 201e, especially an air source interface; the interlayer space 201c connects a plurality of medium channels 201b to the medium source interface 201e (air source interface); the medium channel 201b is connected to the drop fruit channel 201a.
