[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the utility model provides a technical solution: a packaging equipment for seed production, comprising a first workbench 1, a plurality of conveyor belts 2 are provided on the upper right part of the first workbench 1, and a plurality of equidistant material trays 3 are provided on the upper ends of the plurality of conveyor belts 2. The conveyor belts 2 and the material trays 3 are existing technologies, and the plurality of conveyor belts 2 are controlled by PLC. Each time the conveyor belt 2 works, the corresponding material tray 3 can be moved backward by one work station to cooperate with each packaging work. The plurality of material trays 3 on each conveyor belt 2 are respectively used to package seeds of a certain specification particle size. A second workbench 4 is fixedly installed on the middle part of the upper end of the first workbench 1, and a screening mechanism 5 is provided on the upper left part of the second workbench 4. When the screening mechanism 5 is working, it can screen the input seeds and divide them into multiple specifications with different particle sizes. A quantitative unloading mechanism 6 is provided on the upper right part of the second workbench 4. When the quantitative unloading mechanism 6 is working, it can push the screened seeds into the material tray 3 on its lower side for packaging.

[0024] Specifically, such as Figure 2 and Figure 3 As shown, the screening mechanism 5 includes a feeding tank 51 and a motor 52. The feeding tank 51 is located on the upper side of the motor 52. The motor 52 is fixedly installed on the upper left side of the second workbench 4. The outer surface of the feeding tank 51 is provided with a plurality of supporting legs, and the supporting legs are used to fix the position of the feeding tank 51. The output end of the motor 52 is fixedly connected to a rotating shaft 53 passing through the feeding tank 51. The inner surface of the feeding tank 51 is fixedly connected to a plurality of filter plates 54. The rotating shaft 53 is rotatably connected to the plurality of filter plates 54. Therefore, when the motor 52 is working, it will drive the rotating shaft 53 to rotate continuously and will not be affected by the filter plates 54.

[0025] Furthermore, the filter plate 54 is in the shape of a disc that bulges upward or is concave downward, and the adjacent filter plates 54 are convex or concave in opposite directions. Therefore, when the seeds are on the upper surface of the filter plate 54, they will roll outward or inward along the convex or concave inclined surface of the upper surface of the filter plate 54, thereby increasing the range of movement of the seeds on the upper surface of the filter plate 54.

[0026] The filter plate 54 located on the uppermost side is convex upward. After the seeds are thrown into the opening at the upper end of the feeding tank 51, they will first fall on the middle of the upper surface of the uppermost filter plate 54, and fall along the convex inclined surface to the outer side of the upper surface of the uppermost filter plate 54.

[0027] In addition, the outer surfaces of the multiple filter plates 54 are provided with multiple leakage holes 541 that pass through from top to bottom. The diameter of the leakage holes 541 on the outer surface of the filter plate 54 located on the upper side is larger than the diameter of the leakage holes 541 on the outer surface of the filter plate 54 located on the lower side, that is, the leakage holes 541 opened on the surfaces of the multiple filter plates 54 decrease in size from top to bottom. The leakage holes 541 can block seeds with a particle size larger than their diameter.

[0028] Therefore, when the seeds fall naturally on the surface of the filter plate 54 due to gravity, the seeds with a particle size smaller than the diameter of the corresponding leakage hole 541 will fall to the surface of the next filter plate 54, continue to slide on the inclined surface of the next filter plate 54 and pass through the screening of the leakage hole 541 until they are larger than the diameter of the corresponding leakage hole 541 and are blocked.

[0029] Furthermore, the outer surface of the rotating shaft 53 is fixedly connected to the positions of multiple filter plates 54, and each set of toggle plates 542 is in contact with the upper surface of the corresponding leakage hole 541. When the rotating shaft 53 rotates, it will drive the multiple sets of toggle plates 542 to rotate, which can move the seeds on the surface of the filter plate 54 and screen them again, avoiding omissions in the previous natural falling screening process.

[0030] In order to quantitatively package the seeds after screening, Figure 4As shown, the quantitative feeding mechanism 6 includes a mounting block 61 fixedly mounted on the right upper end of the second workbench 4, and a plurality of through slots penetrating front and rear are provided at the front end of the mounting block 61, and push blocks 63 are slidably mounted in the plurality of through slots, and a storage port 64 penetrating up and down is provided at the upper rear end of the push block 63. The upper end of the mounting block 61 corresponding to the plurality of storage ports 64 is provided with a feeding channel 66, and the inner surface bottom walls of the plurality of through slots corresponding to the storage ports 64 are embedded with pressure sensors 65. The positions of the plurality of push blocks 63 corresponding to the front right side of the upper end of the second workbench 4 are fixedly mounted with electric push rods 62, and the output ends of the plurality of electric push rods 62 are fixedly connected to the corresponding push blocks 63. If seeds can be continuously input through the feeding channel 66, the storage port 64 will be filled. At this time, the pressure sensor 65 will detect that the weight on its upper side reaches the set value, and the pressure sensor 65 will transmit a signal to the electric push rod 62 to control the operation of the electric push rod 62, and the electric push rod 62 will push the push block 63 backward (as shown in FIG. Figure 5 working state), a feed opening 41 is provided at the position of multiple push blocks 63 corresponding to the rear right side of the upper end of the second workbench 4, and the storage port 64 is pushed to the position of the feed opening 41. A material tray 3 corresponds to the lower side of the feed opening 41 to catch the fallen seeds.

[0031] In addition, the lower surfaces of multiple filter plates 54 are provided with a discharge pipe 55 that is connected to the discharge channel 66. The starting end of the discharge pipe 55 is connected to the upper surface of the filter plate 54. Therefore, when the rotating shaft 53 drives the multiple sets of toggle plates 542 to rotate continuously, the seeds will be toggled by the toggle plates 542, and enter the discharge pipe 55 when passing the starting end of the discharge pipe 55, and fall into the discharge channel 66 through the discharge pipe 55 until the storage port 64 is filled, and then the above-mentioned electric push rod 62 is triggered to work.

[0032] It should be noted that when the seeds fall, a small amount of incompletely screened seeds may fall directly into the discharge pipe 55, but the starting end of the discharge pipe 55 occupies a small proportion of the upper surface of the filter plate 54, and after multiple screenings, the particle size of these seeds is also similar, and these seeds are within a reasonable error range.

[0033] The working principle of the present invention is as follows: when the seed production packaging equipment is in operation, the seeds are put into the packaging equipment from the opening at the upper end of the feeding tank 51 and fall onto the middle of the upper surface of the uppermost filter plate 54, and then fall along the raised inclined surface to the outer side of the upper surface of the uppermost filter plate 54;

[0034] When seeds fall naturally on the surface of the filter plate 54 due to gravity, seeds with a particle size smaller than the diameter of the corresponding leakage hole 541 will fall to the surface of the next filter plate 54, continue to slide on the inclined surface of the next filter plate 54 and pass through the leakage hole 541 until they become larger than the diameter of the corresponding leakage hole 541 and are blocked;

[0035] When the motor 52 is working, it will drive the rotating shaft 53 to rotate continuously, which will drive the rotation of the multiple toggle plates 542, and can toggle the seeds to move on the surface of the filter plate 54 for screening again, thereby avoiding omissions in the previous natural falling screening process;

[0036] When the seeds are moved by the moving plate 542 , they enter the feeding tube 55 when passing the starting end of the feeding tube 55 , and fall into the feeding channel 66 through the feeding tube 55 until the storage port 64 is filled.

[0037] When the storage port 64 is full of seeds, the pressure sensor 65 will detect that the weight on its upper side has reached the set value. The pressure sensor 65 will transmit a signal to the electric push rod 62 to control the operation of the electric push rod 62. The electric push rod 62 will push the push block 63 backward to push the storage port 64 to the position of the discharge port 41. The lower side of the discharge port 41 corresponds to a material tray 3 that can catch the fallen seeds.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
