DETAILED DESCRIPTION

[0018] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Example

[0020] A kiwifruit seed selection device, such as Figure 1 As shown, it includes an air separation box 1 and a flotation box 11; a fan 3 is installed on the outer wall of the air separation box 1, and a plurality of air holes 6 are opened on its side wall; a hopper 7 is connected to the top of one end of the air separation box 1 close to the fan 3; a first sorting chamber 5 and a second sorting chamber 4 are sequentially arranged at the lower part of the air separation box 1; a discharge valve 10 is arranged at the discharge port of the first sorting chamber 5 close to the hopper 7; and the flotation box 11 is located below the first sorting chamber 5.

[0021] The kiwifruit seed selection device is configured to select kiwifruit seeds by placing kiwifruit seeds from a hopper 7 and continuously blowing air from a fan 3 into an air selection box 1. Some shrunken and underdeveloped seeds are relatively light and are blown to the top of the second selection chamber 4 by the wind and fall into the second selection chamber 4. The remaining seeds fall into the first selection chamber 5 and are opened by opening a discharge valve 10 so that the seeds fall into the flotation box 11 below for secondary seed selection. Unqualified seeds float on the surface of the seed selection liquid, while qualified seeds sink into the flotation box 11.

[0022] Specifically, a blocking cover 9 is detachably mounted on the discharge port of the second separation chamber 4, and a protective cover 2 is disposed outside the fan 3. During air separation, the blocking cover 9 plays a role in blocking the discharge port.

[0023] Specifically, an inclined mesh plate 8 is installed in the inner cavity of the air separation box 1; the upper end of the mesh plate 8 is inclined above the second sorting cavity 4. By reasonably setting the size of the mesh holes of the mesh plate 8, wind can pass through the mesh holes, but seeds can be blocked from passing through. Some seeds hit the surface of the mesh plate 8 under the action of the lateral wind force, and provide a reverse action to the seeds, which can prevent the seeds from sticking to the surface of the mesh plate 8 under the action of the wind force and blocking the mesh holes.

[0024] Specifically, in order to prevent the seeds from sticking to the surface of the mesh plate 8 and clogging the mesh holes, a vibrator 18 is installed on the side wall of the mesh plate 8 .

[0025] Specifically, a plurality of air outlets 19 are provided at the bottom of the end of the air separation box 1 away from the hopper 7. The air outlets 19 are arranged at the bottom to prevent the blown wind from interfering with nearby equipment or staff, and also facilitate the collection of impurities such as fine dust blown out by the wind.

[0026] Specifically, in order to collect qualified seeds conveniently, the flotation box 11 is connected to the collection box 12 through the first pipe 14; the first circulation pump 20 is installed on the first pipe 14; the filter frame 13 is installed in the inner cavity of the collection box 12; the first circulation pump 20 can pump the liquid in the flotation box 11 into the filter frame 13 through the first pipe 14. After the flotation is completed, the unqualified seeds floating on the surface of the seed selection liquid are fished out, and then the first circulation pump 20 is turned on to pump the liquid mixed with qualified seeds into the collection box 12, and then the qualified seeds are intercepted by the filter frame 13, and the seed selection liquid falls through the filter frame 13. The qualified seeds can be taken out by simply taking out the filter frame 13.

[0027] Specifically, for easy installation, a folding plate is connected to the top of the filter frame 13; the filter frame 13 is mounted on the top of the collection box 12 through the folding plate; one end of the first pipe 14 passes through the filter frame 13. When the filter frame 13 needs to be taken out upward, the first pipe 14 or the collection box 12 is moved so that the first pipe 14 is pulled out of the filter frame 13.

[0028] Specifically, a sleeve 15 is installed at one end of the first pipe 14; the sleeve 15 can move along the axial direction of the first pipe 14; the sleeve 15 filters the frame 13 and extends into the inner cavity of the filter frame 13; a handle 17 is fixedly connected to the outer wall of the sleeve 15. By holding the handle 17 to control the axial movement of the sleeve 15 along the first pipe 14, the sleeve 15 can be inserted into or removed from the filter frame 13, thereby avoiding moving the collection box 12.

[0029] Specifically, a vibrator 18 is installed at the bottom of the filter frame 13. The bottom of the filter frame 13 is tilted, and the end close to the first pipe 14 is the high end. The vibrator 18 vibrates when it works, which can cause the seeds intercepted at the bottom of the filter frame 13 to roll to the lower side to prevent them from clogging the mesh.

[0030] Specifically, the lower part of the side wall of the collection box 12 is connected to the flotation box 11 through the second pipe 16; the second circulation pump 21 and the control valve 22 are installed on the second pipe 16. By opening the second circulation pump 21 and the control valve 22, the seed selection liquid in the collection box 12 is pumped back into the flotation box 11, so as to facilitate the recycling of the seed selection liquid.

[0031] Working principle of the embodiment:

[0032] Turn on the fan 3, put the kiwifruit seeds from the hopper 7, and the fan 3 continues to blow air into the air selection box 1 to select the kiwifruit seeds. Some shriveled and underdeveloped seeds are relatively light, and are blown to the top of the second sorting chamber 4 under the action of wind force, and fall into the second sorting chamber 4, while the remaining seeds fall into the first sorting chamber 5. Open the discharge valve 10 to allow the seeds to fall into the flotation box 11 below for secondary seed selection. Unqualified seeds float on the surface of the seed selection liquid, and qualified seeds sink into the flotation box 11. After the flotation is completed, the unqualified seeds floating on the surface of the seed selection liquid are fished out, and then the first circulation pump 20 is turned on to pump the liquid mixed with qualified seeds into the collection box 12, and then the qualified seeds are intercepted by the filter frame 13, and the seed selection liquid falls through the filter frame 13. After the process is completed, the sleeve 15 can be inserted into or removed from the filter frame 13 by holding the handle 17 to control the axial movement of the sleeve 15 along the first pipe 14, so that the filter frame 13 can be taken out without moving the collection box 12, thereby taking out qualified seeds. By opening the second circulation pump 21 and the control valve 22, the seed selection liquid in the collection box 12 is pumped back into the flotation box 11, which is convenient for recycling the seed selection liquid. The seed selection liquid can be water, or a liquid with a density greater than water. The utility model can also be applied to seed selection operations of other crops, and it only needs to reasonably adjust the air volume of the fan 3 according to the size and weight of the seeds, and select an appropriate mesh size.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
