Description

Technical Field

[0001] The invention relates to the field of counting, and in particular to a seed counting, detecting and conveying device and a conveying method for corn detection. Background Art

[0002] Seed counting equipment usually includes a high-precision camera, a backlight device, image processing software, and a container for placing seeds. These devices can automatically identify and count seeds, and provide parameters such as the number, size, and shape of seeds. The latest seed counting equipment may have a high-pixel camera, autofocus function, and intelligent management function to upload data via wireless network.

[0003] Chinese patent application CN118246473A discloses a seed counting device, including a visual detection device, which is used to image the seeds in the image acquisition area and analyze and count them in cooperation with an industrial computer, and also includes: a workbench, a front-stage conveying component, a quantity control component and a rear-stage conveying component. The front-stage conveying component and the rear-stage conveying component are used to convey the seeds, so that when the seeds fall from the front-stage conveying component to the rear-stage conveying component, the speed difference is used to achieve dispersion and flattening, thereby reducing the phenomenon of seed squeezing and superposition. The scraper is used to adjust its angle to control the vertical distance between itself and the discharge end of the front-stage conveying component, so that the number of seeds conveyed by the front-stage conveying component to the rear-stage conveying component can be controlled, and the scraper is used to flatten the seeds originally superimposed on the front-stage conveying component as much as possible, which is more conducive to avoiding the occurrence of superposition after the seeds fall to the rear-stage conveying component.

[0004] Chinese patent CN209496400U discloses a seed counting device, including a base, a counting board, and a seed adding groove. The base includes an L-shaped bracket arranged on the left and right, and the L-shaped bracket is composed of a horizontal part and a vertical part. The seed adding groove is a long box-shaped body and is fixed obliquely on the top of the vertical part. The lower part of the lower side wall of the seed adding groove is provided with a leakage opening, and the leakage opening is a long strip through hole. The counting board is obliquely installed on the L-shaped bracket immediately below the leakage opening. The upper surface of the counting board is provided with seed positions, and the seed positions are multiple and distributed in a honeycomb shape. The seed counting device has a compact structure, a small volume, and is easy to operate.

[0005] The above patents and prior art also have the following defects:

[0006] The counting device in the prior art is installed on the conveyor belt to detect the number of seeds transmitted on the conveyor belt, but the seeds on the conveyor belt are prone to overlap, resulting in inaccurate counting. Some evenly feeding cannot completely avoid the phenomenon of seed overlap. Some scrapers are set to flatten the seeds on the conveyor belt, which has a poor seed dispersion effect. The height of the scraper is difficult to adjust, and when the seeds located above the overlapping seeds are pushed, the seeds below are easily pushed to move together, resulting in large areas of vacancies on the conveyor belt, which is more likely to cause seed overlap, and also reduces the transmission efficiency of the conveyor belt. It is impossible to accurately separate the seeds on the conveyor belt, and the seed counting is inaccurate.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1: Reference Figure 1 - Fig.13 A seed counting detection and conveying device shown includes a counting conveyor belt 1, a counting assembly 2 is arranged on the counting conveyor belt 1, a feeding assembly 3 is also arranged at one end of the counting conveyor belt 1, the feeding assembly 3 can pass seed particles into the counting conveyor belt 1, the counting conveyor belt 1 can transmit the seed particles to the counting assembly 2, and the counting assembly 2 can count the seed particles on the counting conveyor belt 1;

[0046] The feed assembly 3 includes a feed wheel 31, a negative pressure shell 32 and a push unit 33. The feed wheel 31 can rotate, and is provided with a plurality of feed slots 311. The negative pressure shell 32 is arranged on the inner wall of the feed wheel 31.

[0047] The ejection unit 33 includes a plurality of ejection cylinders 331. When the feed groove 311 on the feed wheel 31 rotates to be connected with the negative pressure shell 32, the negative pressure shell 32 can generate negative pressure in the feed groove 311 through the ejection cylinder 331. The ejection cylinder 331 slides in the feed groove 311. When the feed groove 311 on the feed wheel 31 rotates to above the counting conveyor belt 1, the ejection cylinder 331 moves out of the feed groove 311.

[0048] The seed particles are placed on the feed wheel 31, and the seed particles enter the feed trough 311 on the feed wheel 31. The negative pressure shell 32 negatively absorbs the single seed particles in the feed trough 311 through the push-out cylinder 331. The feed wheel 31 rotates. As the feed wheel 31 rotates, the excess seed particles in the feed trough 311 fall from the feed trough 311, and only one adsorbed seed particle is retained. The feed wheel 31 continues to rotate, and the feed trough 311 rotates to separate from the negative pressure shell 32. The negative pressure shell 32 no longer absorbs the seed particles through the push-out cylinder 331. At the same time, the push-out cylinder 331 moves out of the feed trough 311 to push the seed particles in the feed trough 311 out of the feed trough 311. The seed particles fall onto the counting conveyor belt 1, and the counting conveyor belt 1 transmits the seed particles to the counting component 2. The counting component 2 counts the seed particles on the counting conveyor belt 1.

[0049] The seed particles are allowed to enter the feed trough 311, and one seed particle in the feed trough 311 is attracted by negative pressure. The other particles in the feed trough 311 fall as the feed wheel 31 rotates, so that only one seed particle is retained in the feed trough 311, and the seed particles falling onto the counting conveyor belt 1 will not overlap with each other, the distance between the seed particles is more uniform, the counting component 2 can count the seed particles more accurately, and there will be no errors in the counting of the seed particles due to the overlapping of the seed particles. The seed particles are attracted by negative pressure through the push-out cylinder 331, so as to achieve the effect of only attracting one seed particle by negative pressure, thereby ensuring that the seed particles will not overlap when they fall onto the counting conveyor belt 1, and at the same time, the push-out cylinder 331 can push the seed particles out of the feed trough 311 to prevent the seed particles from being stuck in the feed trough 311.

[0050] Example 2, reference Figure 1 - Fig.13 , which is different from the above-mentioned embodiment, the feed assembly 3 also includes a feed shell 34, a discharge shell 35 and a lower shell 36. The top and bottom of the feed shell 34 are both opened, the bottom of the feed shell 34 abuts against the feed wheel 31, the discharge shell 35 is fixedly mounted on one side of the feed shell 34, the lower shell 36 is fixedly mounted on one side of the discharge shell 35 and abuts against the bottom of the feed wheel 31, and the negative pressure shell 32 abuts against the inner wall of the feed wheel 31 at the position of the feed shell 34 corresponding to the inner wall of the feed wheel 31.

[0051] The seed particles are added into the feed shell 34, and the seed particles enter the feed trough 311 on the feed wheel 31. The negative pressure shell 32 negatively absorbs a seed particle in the feed trough 311 through the push-out cylinder 331. The feed wheel 31 rotates. When the feed trough 311 on the feed wheel 31 moves to the position of the discharge shell 35, the opening of the feed trough 311 tilts downward, and the excess seed particles in the feed trough 311 are separated from the feed trough 311 and discharged through the discharge shell 35 for reuse, and only one seed particle attracted by negative pressure is retained. When the feed trough 311 on the feed wheel 31 moves to the position of the discharge shell 36, the negative pressure shell 32 no longer attracts the seed particles through the push-out cylinder 331. At the same time, the push-out cylinder 331 pushes the seed particles out of the feed trough 311, and the seed particles fall onto the counting conveyor belt 1 through the discharge shell 36.

[0052] Example 3, reference Figure 1 - Fig.13 , which is different from the above-mentioned embodiment, there are several pushing units 33, and each pushing unit 33 corresponds to the longitudinally arranged feed grooves 311 on the feed wheel 31, and the pushing unit 33 includes a pushing shell 332 and several negative pressure cylinders 333, the negative pressure cylinder 333 is fixedly installed on the pushing shell 332, and the bottom of the negative pressure cylinder 333 passes through the pushing shell 332, the pushing cylinder 331 is sleeved on the negative pressure cylinder 333 and slidably cooperates with the negative pressure cylinder 333, and the pushing shells 332 in two adjacent pushing units 33 are fixedly installed to each other.

[0053] When the pushing unit 33 moves to the position of the negative pressure shell 32, the negative pressure cylinder 333 is connected to the negative pressure shell 32, and the negative pressure shell 32 generates negative pressure in the pushing cylinder 331 through the negative pressure cylinder 333, and the pushing cylinder 331 attracts the seed particles in the feed trough 311 through the negative pressure. When the pushing unit 33 moves to the position of the unloading shell 36, the negative pressure cylinder 333 is separated from the negative pressure shell 32, and the negative pressure in the negative pressure cylinder 333 and the pushing cylinder 331 disappears, and at the same time, the pushing cylinder 331 moves outside the feed trough 311, pushing the seed particles in the feed trough 311 out of the feed trough 311 and dropping them onto the counting conveyor belt 1.

[0054] Example 4, reference Figure 1 - Fig.13 , which is different from the above embodiment, the pushing unit 33 also includes a pushing plate 334, a return spring 335, an extrusion plate 336 and an extrusion wheel 337. Pushing plates 4 are arranged on both sides of the feeding wheel 31. Pushing protrusions 5 are fixedly installed on the pushing plates 4. The pushing protrusions 5 are located on the pushing plates 4 at positions corresponding to the unloading shell 36. The pushing plate 334 is slidably fitted in the pushing shell 332. The extrusion plate 336 is fixedly installed on the pushing plate 334. The extrusion plate 336 penetrates the pushing shell 332 and slidably fits with the pushing shell 332. The extrusion plate 336 extends to the outside of the pushing shell 332. The extrusion wheel 337 is fixedly installed on the extrusion plate 336. The extrusion wheel 337 can be moved on the pushing plate 4. One end of the return spring 335 is fixedly installed on the pushing plate 334, and the other end of the return spring 335 is fixedly installed on the inner wall of the feeding wheel 31.

[0055] The feeding wheel 31 drives the ejection shell 332 and the extrusion wheel 337 to move in a circular motion. The extrusion wheel 337 moves on the pushing plate 4. When the ejection unit 33 moves to the position of the unloading shell 36, the extrusion wheel 337 moves to the position of the pushing protrusion 5. The pushing protrusion 5 pushes the extrusion wheel 337 to move. The extrusion wheel 337 pushes the extrusion plate 336 to move into the ejection shell 332. The extrusion plate 336 drives the ejection plate 334 to move. The ejection plate 334 squeezes the reset spring 335 and drives the ejection cylinder 331 to move at the same time. The ejection cylinder 331 The push wheel 337 moves outward from the feed trough 311 to push out the seed particles in the feed trough 311. As the movement progresses, when the extrusion wheel 337 moves from the pushing protrusion 5 to the pushing plate 4, the reset spring 335 drives the pushing plate 334 to reset, and the pushing plate 334 drives the pushing cylinder 331 to reset. As the feed wheel 31 rotates, the negative pressure cylinder 333 moves back to the position of the negative pressure shell 32. The negative pressure shell 32 generates negative pressure in the pushing cylinder 331. The pushing cylinder 331 attracts the seed particles in the feed shell 34 into the feed trough 311 under negative pressure.

[0057] The pushing motor 62 drives the pushing screw 61 to rotate, and the pushing plate 63 moves on the pushing screw 61. The pushing plate 63 drives the pushing brush 64 to move on the feeding wheel 31 to push the seed particles into the feeding trough 311, ensuring that at least one seed particle enters the feeding trough 311, preventing high-frequency particle shortages on the counting conveyor belt 1, improving the transmission capacity of the counting conveyor belt 1, and preventing the spacing between seed particles on the counting conveyor belt 1 from becoming larger due to particle shortages in the feeding trough 311, thereby solving the problem of reducing the transmission capacity of the counting conveyor belt 1.
