When the seedling emergence test or the germination contrast test of the plant seeds is carried out, the test seeds and the control seeds are always required to be uniformly placed on the same seed distribution disc, and 1 seed must be ensured to be sown in each hole. In general, only manual seeding is adopted, but the manual seeding efficiency is low and the labor intensity is high. Therefore, in the process of seed germination rate and other tests, how to quickly and accurately pick seeds and reduce the adverse effects of human factors so as to ensure the representativeness, the consistency and the placing uniformity of the picked seeds is the key for improving the labor efficiency and ensuring the objective test results.

Referring to fig. 1-4, embodiments of the present application provide a seed spreader 10. The spreader 10 includes a support 100, a spreader plate 200, and a barrier plate 300. The seed scattering plate 200 is fixedly arranged on the bracket 100. The seed scattering plate 200 is provided with a plurality of positioning holes 210. The alignment aperture 210 includes an inlet 212 and an outlet 214. The inlet 212 is used to allow the seed 420 to enter the locating hole 210, and the outlet 214 is used to allow the seed 420 to exit the locating hole 210. Each of the positioning holes 210 is sized to fit the volume of one of the seeds 420, and the positioning holes 210 are configured to receive one of the seeds 420. The blocking plate 300 is detachably disposed on the support 100, and the blocking plate 300 is used for blocking the outlets 214 of the positioning holes 210 so as to limit the seeds 420 in the positioning holes 210.

In this embodiment, the support 100 may be a frame structure. The seed spreader 200 may be erected or fixed on the stand 100. The seed scattering plate 200 may be horizontally disposed. The cross-section of the positioning hole 210 may be circular or elliptical. The cross-section of the positioning hole 210 may be designed according to the shape of the seed 420, so as to store one seed 420. The plurality of positioning holes 210 may be arranged in an array. The positioning holes 210 may be located corresponding to the acupoints of the seeds 420 in the seed arrangement disc 400. Therefore, after the positioning holes 210 are filled with the seeds 420, the seeds 420 can directly fall into the acupuncture points in the seed distribution plate 400. The blocking plate 300 may be disposed at one side of the seed sowing plate 200, i.e., to block the outlet 214, so that the seeds 420 may be released according to a desired sowing time. When it is necessary to release the seeds 420, the blocking plate 300 may be disassembled, and the seeds 420 may fall into the seed distribution plate 400. When it is desired to have the seeds 420 remain in the positioning holes 210, the blocking plate 300 may be positioned at the bottom of the outlets 214 of the plurality of positioning holes 210.

When the seed scattering plate 200 is used, more seeds 420 may be covered on the surface of the seed scattering plate 200, and then one seed 420 may be dropped into each positioning hole 210 by a sweeping motion. It is understood that since the height and diameter of the positioning holes 210 are designed according to the shape of the seeds 420, each positioning hole 210 can be filled with only one seed 420, and the excess seeds 420 remain on the surface of the seed sowing plate 200. When one seed 420 falls into each of the plurality of positioning holes 210, the excess seed 420 left on the surface of the seed sowing plate 200 is swept away, and then the support 100 or the seed distribution plate 400 can be moved so that the positioning holes 210 correspond to the acupoints of the seeds 420 in the seed distribution plate 400. Then, the blocking plate 300 is removed from the support 100, and the seeds 420 in the positioning holes 210 fall to the acupuncture points of the seeds 420. Therefore, the seed spreader 10 provided by the embodiment of the application can simultaneously spread seeds on a plurality of fixed acupuncture points, and the working efficiency is improved.

In one embodiment, the holder 100 is provided with a withdrawal socket 110. The extraction opening 110 is used to pass through the baffle plate 300. So that the blocking plate 300 is inserted into or withdrawn from the bracket 100. The drawing port 110 may be a horizontally disposed strip-shaped opening. The length and width of the bar-shaped opening may correspond to those of the barrier plate 300. The blocking plate 300 can enter the support 100 through the drawing opening 110 and be fixed to the outlets 214 of the positioning holes 210 to block the seeds 420 from falling off from the positioning holes 210. When the seeds 420 need to be sown, the blocking plate 300 can be pulled out from the bracket 100 through the inserting hole 110, and the seeds 420 can fall off from the positioning holes 210.

In one embodiment, one end of the barrier plate 300 is provided with a handle 310. The handle 310 is used for inserting the blocking plate 300 into the support 100, so that the blocking plate 300 blocks the outlets 214 of the positioning holes 210. The handle 310 is also used to pull the blocking plate 300 away from the support 100 to release the seeds 420 from the exit 214 of the positioning hole 210. The handle 310 may be T-shaped or rectangular. The position of the barrier plate 300 is conveniently controlled by the handle 310 to improve work efficiency.

In one embodiment, the stent 100 includes a seeding cavity 120. The seeding cavity 120 is disposed on a side of the baffle plate 300 away from the seeding plate 200. The seed 420 exits the alignment aperture 210 from the exit 214 of the alignment aperture 210 and then falls through the seeding chamber 120 to a target location. The seeding chamber 120 may be located below the blocking plate 300, and after the blocking plate 300 leaves the outlet 214 of the positioning hole 210, the seeds 420 fall from the outlet 214 and enter the seeding chamber 120. The seeds 420 fall through the seeding chamber 120 into the seed distribution tray 400.

In one embodiment, the seeding cavity 120 includes a plurality of seeding channels 122. The seeding channels 122 are arranged in one-to-one correspondence with the positioning holes 210, and the seeds 420 fall from the outlets 214 of the positioning holes 210 and then fall to the target positions through the seeding channels 122. The barrier plate 300 may be disposed between the seed 420 passage and the corresponding positioning hole 210. When the blocking plate 300 is pulled away, the seeds 420 leave the positioning hole 210 and enter the seeding channel 122 corresponding to the positioning hole 210. The outlet 214 of the sowing channel 122 may correspond to the acupuncture points of the seeds 420 in the seed arrangement disc 400, so that the seeds 420 may directly fall into the acupuncture points of the seeds 420 through the sowing channel 122. The seeding channel 122 can avoid the problem that the seeds 420 are deviated from the falling trajectory due to the vibration or air flow of the seed broadcaster 10, so that the seeds cannot fall into the target acupoints. The seeding channel 122 thus improves the reliability of seeding.

In one embodiment, the seeding chamber 120 includes a plurality of channel plates 124. The plurality of channel plates 124 are arranged crosswise to form the seeding channel 122. The seeding channels 122 in the crisscross shape of the channel plates 124 can correspond to the positioning holes 210 one by one, and the crisscross form of the channel plates 124 is simple in structure and low in manufacturing cost.

In one embodiment, the edge of the inlet 212 is provided with a guide structure 213. It is understood that when the seed 420 is a shaped seed 420, such as a curved seed 420 or an ellipsoidal seed 420, the seed 420 can be easily inserted into the positioning hole 210 through the guide structure 213. The guide structure 213 may be a step structure or an arc-shaped slide way disposed at the inlet 212.

In one embodiment, the guide structure 213 includes a chamfer disposed at an edge of the inlet 212. The chamfer may be a right angle chamfer or an arc chamfer. The area of the inlet 212 can be enlarged by providing a chamfer on the inlet 212, which can facilitate the sliding of the shaped seed 420 into the positioning hole 210.

In one embodiment, the diameter of the pilot hole 210 is less than the diameter of the seeding channel 122. In order to prevent the seeds from being caught in the gap between the positioning hole 210 and the seeding channel 122 after the blocking plate 300 is pulled open, the diameter of the seeding channel 122 may be larger than the diameter of the positioning hole 210. And when the blocking plate 300 is pulled open, the seeds fall directly and quickly through the seeding channel 122.

In one embodiment, the blocking plate 300 is provided with a plurality of through holes corresponding to the plurality of positioning holes 210 one to one. The blocking plate 300 is disposed on the support 100, and when the positioning hole 210 is misaligned with the through hole, the seed is limited in the positioning hole 210 by the blocking plate 300. When the positioning hole 210 is opposite to the through hole, the seed is dropped from the outlet 214.

In this embodiment, the blocking plate 300 does not need to be completely withdrawn, the blocking plate 300 may be provided with the same number of through holes as the positioning holes 210 of the seed sowing plate 200, the through holes may be staggered from the positioning holes 210 by adjusting the position of the blocking plate 300 before sowing seeds on the seed sowing plate 200, and then the seeds are sown on the seed sowing plate 200, and after one seed is in each hole, the excess seeds are swept out of the seed sowing plate 200. At this time, the through hole of the barrier plate 300 may be aligned with the positioning hole 210 by moving the position of the barrier plate 300, and the seed in the positioning hole 210 may drop through the through hole.

In one embodiment, the spreader 10 further includes a seed distribution tray 400. The seed distributing plate 400 is disposed on a side of the blocking plate 300 away from the seed spreading plate 200, and is used for receiving the seeds 420 falling from the outlet 214 of the positioning hole 210. The seed distribution plate 400 may be provided with a plurality of acupuncture points of the seeds 420, and the positions of the acupuncture points of the seeds 420 may correspond to the positions of the positioning holes 210. The seeds 420 may grow in the acupoints of the seeds 420.

In one embodiment, the seed distribution tray 400 has filter paper 410 disposed therein. The filter paper 410 for the germination test of the seeds 420 may be a qualitative filter paper 410 and a quantitative filter paper 410. The filter paper 410 can have sufficient moisture without affecting the permeability of air, thereby ensuring the normal growth of the seeds 420.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
