In order to understand the working principle of the corn pollen collecting system provided by the embodiment of the application more clearly, firstly, the using environment of the corn pollen collecting system is simply introduced, the corn pollen collecting system disclosed by the embodiment of the application is mainly used on an automatic corn breeding production line, corn plants are planted in culture dishes independently, the culture dishes with the corn plants can be placed on a transportation production line to move continuously, and when each corn plant moves below the corn pollen collecting system disclosed by the embodiment of the application, pollen can be collected.

Alternatively, the corn pollen collection system disclosed in the embodiments of the present application is installed on a mobile system, and the mobile system can move above a culture dish with corn plants, and when moving above each corn plant, pollen on each corn plant can be collected.

Referring to fig. 3, in conjunction with a specific pollen collection process, when a corn plant moves below the cage gripper 14, the cage gripper 14 opens, and during this process, the flexible cover 15 expands as the cage gripper 14 opens. Then, the piston of the first telescopic unit 13 will move to the direction close to the corn plant, so that the flexible cover 15 can cover the head of the corn plant.

The cage gripper 14 is then closed so that the flexible cover 15 can wrap the head of the corn plant. After the head of the corn plant is wrapped by the flexible cover 15, the flexible expansion body 17 and the flexible purging pipeline 18 start to act simultaneously, the action process of the flexible expansion body 17 is continuous expansion and reduction, and in the process, the flexible expansion body 17 can flap the head of the corn plant, so that pollen on the head of the corn plant falls off; the flexible purge line 18 blows out a large volume of air to blow the dislodged pollen into the transfer passage 16.

After the collection is completed, the cage-type gripper 14 is opened, the piston of the first telescopic unit 13 returns to the initial position, at this time, the flexible cover 15 is separated from the head of the corn plant, and then the corn pollen collection system disclosed by the embodiment of the application can move to the top of the next corn plant and repeat the process.

Overall speaking, the disclosed maize pollen collection system of this application embodiment has used the mode of patting to gather the pollen on the maize plant, and this kind of mode can the at utmost guarantee maize plant's integrality because at the natural pollination in-process of reality, the wind blows maize plant or blows maize plant and rocks, and the pollen on the maize plant will drop. And this kind of mode can also effectively improve the collection volume of pollen, because the pollen of these collections will be used for the artificial pollination in later stage, compares in the process of natural pollination, and the demand volume of artificial pollination to pollen can be bigger.

In addition, in the process of spraying air through the flexible blowing pipeline 18, a part of pollen can be blown to fall off, and the two collection modes are comprehensively used, so that the pollen collection amount can be further improved.

Referring to fig. 1, as a specific embodiment of the corn pollen collecting system provided by the application, the cage-type gripper 14 is composed of a plurality of cantilevers 141, a swing arm 142, a micro cylinder 143, and the like, the cantilevers 141 are uniformly fixed to a working end (i.e., a piston) of the first telescopic unit 13, a first end of the swing arm 142 is hinged to the cantilevers 141, a second end is a free end and can swing under the driving of the micro cylinder 143, and the micro cylinder 143 is disposed on the cantilevers 141.

In some possible implementations, the micro cylinder 143 is hinged at both ends to the cantilever 141 and the swing arm 142, respectively.

A plurality of cantilevers 141 evenly set up on the work end (also being the piston) of first flexible unit 13 around the axis of the work end (also being the piston) of first flexible unit 13, and simultaneously, the middle of the three-dimensional shape that cantilever 141 and swing arm 142 enclosed is big, and both ends are little, can live the head parcel of maize plant.

Referring to fig. 1, as a specific embodiment of the corn pollen collecting system provided by the application, the middle portion of the flexible purging tube 18 is fixed on the cantilever 141 and the swing arm 142, which enables the flexible purging tube 18 to deform along with the swing of the swing arm 142, but keeps relatively static with the connected flexible cover 15, so as to effectively reduce the probability of the flexible purging tube 18 and the flexible cover 15 falling off.

Further, the first end of the flexible purge conduit 18 is fixed on the inner wall of the flexible cover 15, for example, the flexible purge conduit 18 may be adhered on the inner wall of the flexible cover 15.

Referring to fig. 4 and 5, as a specific embodiment of the corn pollen collecting system provided by the application, the flexible expansion bodies 17 on the inner wall of the flexible cover 15 are divided into a plurality of groups, the number of the flexible expansion bodies 17 in each group may be one or more, and the plurality of groups of flexible expansion bodies 17 act sequentially, so that the collecting effect is better.

It will be appreciated that if the flexible inflatable body 17 on the inner wall of the flexible cover 15 is inflated and deflated at the same time, the head of the corn plant at the center will shake less and the amount of pollen dropped per shake will be less. When the flexible expansion body 17 on the inner wall of the flexible cover 15 is divided into a plurality of groups and acts sequentially, the shaking degree of the head of the corn plant positioned at the center can be increased, and the pollen collecting efficiency can be further improved.

Referring to fig. 6, as a specific embodiment of the corn pollen collecting system, a collecting module 2 is added, the collecting module 2 is composed of a separating box 21, a separating unit 22, a collecting box 23, and the like, an input end of the separating box 21 is connected to the conveying channel 16, the separating unit 22 is arranged in the separating box 21 and is used for separating the pollen in the air, and an input end of the collecting box 23 is connected to the separating box 21 and is used for storing the pollen separated from the separating box 21.

One part of the separating unit 22 is located in the separating box 21, and the other part extends into the collecting box 23, specifically, after the airflow with pollen contacts the separating unit 22, the pollen is intercepted by the separating unit 22 and falls into the collecting box 23 below, and the airflow flows out from the output end of the separating box 21.

This kind of mode can make the air current in the separator box 21 continuous flow, that is in the pollen collection process, the maize pollen collection system that this application embodiment provided can continuous operation.

Referring to fig. 7 and 8, the separation unit 22 is composed of a plurality of rows of intercepting plates 221, each row of intercepting plates 221 has a plurality of intercepting plates 221, and gaps are formed between adjacent intercepting plates 221 in the same row, and the gaps are used for allowing the air flow to pass through. The first ends of the interception plates 221 are fixed in the separation box 21, the second ends of the interception plates extend into the collection box 23, the interception plates 221 in adjacent rows are arranged in a staggered mode, pollen in the airflow is filtered once when the airflow passes through each row of interception plates 221, and most pollen in the airflow is intercepted and falls into the collection box 23 after being filtered for multiple times.

The principle of the interception is that pollen flowing into the separation box 21 has a certain moving speed, and when the pollen collides with the interception plate 221, the moving speed of the pollen is reduced, and as the number of collisions increases, the moving speed of the pollen is reduced and falls into the collection box 23.

Further, referring to fig. 7 and 8, the side wings 222 are disposed on both sides of the interception plate 221, the side wings 222 extend in the same direction as the gas flow in the separation box 21, and the side wings 222 further reduce the moving speed of the pollen. For example, after the pollen collides with the interception plate 221, part of the pollen moves onto the side wing 222 and moves along the side wing 222 under the driving of the airflow, and in the process, the friction force further reduces the moving speed of the pollen.

The side wings 222 can also guide the movement path of the pollen, so that the pollen can directly impact the rear interception plate 221 or the side wings 222 after being separated from the side wings 222.

Further, referring to fig. 9, the intercepting blind holes 223 are uniformly distributed on the working surface of the intercepting plate 221, and the intercepting blind holes 223 further increase the friction force of the pollen in the moving process on the intercepting plate 221, so as to reduce the moving speed of the pollen.

Further, the working surface of the side wing 222 is an arc-shaped surface, and in the contact process of the arc-shaped surface and the pollen, the moving speed of the pollen can be reduced by using friction force, and a thrust opposite to the moving direction of the pollen can be applied to the pollen, so that the descending amplitude of the moving speed of the pollen can be increased.

Furthermore, the end of the working surface of the side wing 222 is provided with a curved intercepting surface 224, the curved intercepting surface 224 faces the gas flow direction in the separating box 21, and the curved intercepting surface 224 also has the function of reducing the moving speed of the pollen.

For example, when the intercepting curved surface 224 is not provided at the end of the working surface of the wing 222, the pollen may directly slide off from the end of the working surface of the wing 222, the moving speed of the pollen is not substantially changed in the process, and after the intercepting curved surface 224 is added, the pollen first collides with the intercepting curved surface 224 and then slides off from the intercepting curved surface 224 when moving to the end of the working surface of the wing 222, and the moving speed of the pollen is rapidly reduced in the collision process.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
