Technical Field

[0001] The invention relates to the technical field of vegetable seedling cultivation, and in particular to a vegetable seedling cultivation device and a seedling cultivation method thereof. Background Art

[0002] Seedling cultivation means to cultivate seedlings. Originally, it refers to cultivating seedlings in nurseries, hotbeds or greenhouses in preparation for transplanting them into the soil for planting. It can also refer to the stage when various organisms are artificially protected from small scales until they can survive independently. As the saying goes, "a strong seedling is halfway to the harvest." Seedling cultivation is a labor-intensive, time-consuming and technically demanding job.

[0003] When raising vegetable seedlings, automatic sowing is required. The uniformity of sowing will affect the success rate of seedling raising, and the existing sowing machines have insufficient sowing uniformity. Summary of the invention

[0004] In order to overcome the technical defects of the prior art, the present invention provides a vegetable seedling raising device and a seedling raising method thereof to ensure uniform distribution of materials.

[0005] The technical solution adopted by the present invention is:

[0006] A vegetable seedling raising device comprises a vacuum adsorption cylinder, a seed hopper and a vibration blanking device, wherein the vibration blanking device is installed in the vacuum adsorption cylinder, and the vacuum adsorption cylinder is also provided with a plurality of rows of material storage holes arranged along the main line of the vacuum adsorption cylinder, and a normal pressure area is formed between the vibration blanking device and the vacuum adsorption cylinder. The vibration blanking device slides along the inner side of the vacuum adsorption cylinder, and the vibration blanking device vibrates when the vibration blanking device collides with the material storage hole.

[0007] Preferably, the vacuum adsorption cylinder is connected to a vacuum adsorption fan.

[0008] Preferably, the seed hopper fits the vacuum adsorption cylinder.

[0009] Preferably, the vibration blanking device includes a vibration generating frame, an air pressure change bag, a normal pressure tank and a plurality of blowing pipes, both ends of the vibration generating frame are pressed against the inner side of the vacuum adsorption cylinder, the vibration generating frame collides with the material storage hole, the air pressure change bag is installed at the bottom of the vibration generating frame, the normal pressure tank is installed at the bottom of the air pressure change bag, the normal pressure tank slides along the vacuum adsorption cylinder, each blowing pipe is installed in the normal pressure tank, and the air pressure change bag is connected to each blowing pipe.

[0010] Preferably, sliding plates are provided at both ends of the vibration generating frame, the bottom of the sliding plates has a conical surface, the diameter of the sliding plates is larger than the diameter of the material storage holes, the spacing between the sliding plates can ensure that they fall into two material storage holes belonging to different rows at the same time, and each blowing tube just points to the corresponding material storage hole in the middle of the two sliding plates when each sliding plate falls into the corresponding material storage hole.

[0011] Preferably, the air pressure changing bag is a rubber bag.

[0012] Preferably, the width of the atmospheric pressure groove is smaller than the spacing between adjacent material storage holes.

[0013] Preferably, the material storage hole has a smaller diameter close to the inner side of the vacuum adsorption cylinder.

[0014] The seedling raising method uses a vegetable seedling raising device, comprising the following steps:

[0028] The present invention will be further described below in conjunction with the accompanying drawings:

[0029] like Figure 1 — Figure 3 As shown, the present embodiment provides a vegetable seedling raising device, comprising a vacuum adsorption cylinder 1, a seed hopper 2 and a vibration dropping device 3, the vibration dropping device 3 is installed in the vacuum adsorption cylinder 1, and the vacuum adsorption cylinder 1 is also provided with a plurality of rows of storage holes 11 arranged along the busbar of the vacuum adsorption cylinder 1, negative pressure gas is introduced into the vacuum adsorption system, and a normal pressure area is formed between the vibration dropping device 3 and the vacuum adsorption cylinder 1, and then the seeds fall under the action of gravity, and the vibration dropping device 3 slides along the inner side of the vacuum adsorption cylinder 1, and when the vibration dropping device 3 collides with the storage hole 11, the vibration dropping device 3 vibrates to ensure that the seeds fall reliably, and due to the action of gravity, the vibration dropping device 3 is always located at the bottom of the vacuum adsorption cylinder 1, so that the seeds fall at the position of the storage hole 11 at the lowest end.

[0030] Specifically, the rotary axis position of the vacuum adsorption cylinder 1 is connected to the vacuum adsorption fan through a rotary joint, thereby generating negative pressure, and then adsorbing the seeds in the storage hole 11 when the adsorption hole passes through the position of the seed hopper 2.

[0031] Specifically, the seed hopper 2 is attached to the vacuum adsorption cylinder 1 to continuously supply materials.

[0032] Specifically, the vibration blanking device 3 includes a vibration generating frame 31, an air pressure change bag 32, a normal pressure groove 33 and a plurality of blowing tubes 34. Both ends of the vibration generating frame 31 are pressed against the inner side of the vacuum adsorption cylinder 1, the vibration generating frame 31 collides with the material storage hole 11, the air pressure change bag 32 is installed at the bottom of the vibration generating frame 31, the normal pressure groove 33 is installed at the bottom of the air pressure change bag 32, the normal pressure groove 33 slides along the vacuum adsorption cylinder 1, and each blowing tube 34 is installed in the normal pressure groove 33. The air pressure change bag 32 is connected to each blowing tube 34. The vibration generating frame 31 vibrates when passing through the material storage hole 11, and then the capacity of the air pressure change bag 32 changes, so that the blowing tube 34 blows toward the corresponding material storage hole 11, so that the seeds fall safely.

[0033] Specifically, both ends of the vibration generating frame 31 are provided with sliding plates 311, and the bottom of the sliding plates 311 has a conical surface. The diameter of the sliding plates 311 is larger than the diameter of the material storage hole 11, which prevents the material storage hole 11 from rapid wear and increases the service life. In order to allow the air pressure change bag 32 to blow at the right time, the sliding plates 311 and the blowing tubes 34 need to meet such a positional relationship, that is, the spacing between each sliding plate 311 can ensure that it falls into two material storage holes 11 belonging to different rows at the same time, and the blowing tubes 34 just point to the material storage hole 11 corresponding to the middle position of the two sliding plates 311 when each sliding plate 311 falls into the corresponding material storage hole 11, satisfying such After the position relationship is established, the following effect will be produced. The storage holes 11 generate negative pressure due to being connected to the vacuum adsorption fan, so that each storage hole 11 adsorbs the seeds. During the rotation of the vacuum adsorption cylinder 1, the vibration generating frame 31 and the normal pressure groove 33 are always located at the bottom of the vacuum adsorption cylinder 1 under the action of gravity. The seeds in the storage holes 11 located at the position of the normal pressure groove 33 lose the adsorption of the vacuum adsorption fan due to the isolation of the normal pressure groove 33, and the seeds fall onto the soil 5 on the conveyor belt 4 under the action of gravity. Furthermore, since there is a blowing pipe 34 blowing towards the storage holes 11, the seeds can be guaranteed to fall reliably, so that the seed spacing during sowing is strictly uniform, thereby improving the success rate of seedling cultivation.

[0034] Specifically, the air pressure changing bag 32 is a rubber bag, which is easy to deform.

[0035] Specifically, the width of the constant pressure groove 33 is smaller than the spacing between adjacent material storage holes 11, so that the material storage holes 11 are sown row by row to ensure the sowing position.

[0036] Specifically, the diameter of the storage hole 11 near the inner side of the vacuum adsorption cylinder 1 is smaller to prevent seeds from entering the vacuum adsorption cylinder 1 .

[0037] A seedling raising method of a seedling raising device, using a vegetable seedling raising device, comprises the following steps:

[0038] S1: negative pressure gas is introduced into the vacuum adsorption cylinder 1;

[0039] S2: The vacuum adsorption cylinder 1 rotates, and the vibration blanking device 3 slides along the inner side of the vacuum adsorption cylinder 1. The position covered by the vibration blanking device 3 becomes a normal pressure state, and the seeds in the storage hole 11 fall down, ensuring that the seeds fall down reliably.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
