Description

Technical Field

[0001] This invention relates to the field of seed screening technology, and in particular to an agricultural machinery and equipment for screening superior seeds in agricultural planting. Background Technology

[0002] In the process of agricultural planting, the most important thing is the seed. In order to improve the quality of the seed and ensure the germination rate, the seed usually needs to be screened. However, the existing screening equipment can only remove impurities in the seed, as well as seeds that are small in size and have large differences in quality. However, for those seeds that are indistinguishable in size but have been infested by insects, due to the small difference in quality, it is generally difficult to screen them out. They can only be screened out manually. When the planting volume is large, manual screening is inefficient and is prone to omissions and misselections, which affects the germination rate of the seeds. Summary of the Invention

[0003] The purpose of this invention is to provide an agricultural machinery device for screening superior seeds in agricultural planting. The device uses a roller to pick up the seeds one by one to the highest point of the roller, and then weighs the seeds to screen out those that are infested by insects and of the same size. This avoids manual use and ensures the germination rate of the seeds.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] An agricultural machinery device for screening superior seeds in agricultural planting includes a support base, a rotating motor installed inside the support base, a roller installed on the front side of the support base, the roller being connected to the output shaft of the rotating motor, a seed storage box installed on the upper left side of the roller, and one side of the seed storage box being connected to the periphery of the roller.

[0006] The roller has multiple rows of mounting holes evenly distributed around its periphery, with at least two mounting holes in each row. Each mounting hole contains an annular load cell. The lower end of the annular load cell is connected to a flexible tube, which is connected to an air pump. A solenoid valve is mounted on the flexible tube. A control panel is located on the front side of the roller. The annular load cell, air pump, and solenoid valve are all electrically connected to the control panel.

[0007] At least two receiving buckets are placed below the roller, and the positions of the receiving buckets correspond to the mounting holes.

[0008] By adopting the above technical solution, the rotating motor drives the drum to rotate, allowing the mounting holes to pass through the seed storage box in sequence. When the mounting holes pass through the seed storage box, the air pump works to adsorb the seeds onto the ring weighing sensor. When the seeds rotate to the highest point, the seeds are weighed to screen out seeds that do not meet the standards. When the seeds rotate to the upper end of the corresponding receiving hopper, the solenoid valve closes, and the seeds are discharged into the corresponding receiving hopper.

[0009] The further arrangement of the present application is that the roller is internally hollow, the ring-shaped load cell is installed in the roller, a suction pipe is installed at the center boss of the ring-shaped load cell, the suction pipe is arranged in the mounting hole, a gap exists between the circumferential side of the suction pipe and the inner side of the mounting hole, and the end of the suction pipe away from the roller protrudes from the circumferential side of the roller.

[0010] By adopting the above technical scheme, the suction pipe is matched with the mounting hole, and different sizes of seeds can be adapted.

[0011] The further arrangement of the present application is that the diameter of the suction pipe is greater than the diameter of the seed.

[0012] By adopting the above technical scheme, the stability of the seed on the suction pipe is ensured.

[0013] The further arrangement of the present application is that each row of mounting holes corresponds to one air pump, the air pump is installed in the roller, the air-permeable hole is arranged on the roller, and the dust screen is arranged on the air-permeable hole.

[0014] By adopting the above technical scheme, the air pumps are uniformly distributed, and the balance of the rotation of the roller is not affected.

[0015] The further arrangement of the present application is that the receiving barrels are arranged from left to right.

[0016] By adopting the above technical scheme, the seeds are conveniently arranged in the receiving barrels in sequence.

[0017] The further arrangement of the present application is that the seed storage box is in the shape of being small at the lower end and large at the upper end, the seed storage box is connected to the support seat through the first support rod, the upper end right side of the seed storage box is provided with an opening, the upper side of the roller is provided with the air outlet pipe, the air outlet pipe is provided with the air outlet nozzle corresponding to the mounting hole, one end of the air outlet pipe is rotatably connected with the second support rod, the second support rod is connected to the support seat, and the second support rod is provided with the locking knob used in cooperation with the air outlet pipe.

[0018] By adopting the above technical scheme, the air outlet nozzle is used to blow off the excessive seeds adsorbed by the suction pipe, and the weighing result is affected.

[0019] The further arrangement of the present application is that the upper end of the seed storage box is communicated with the feeding hopper.

[0020] By adopting the above technical scheme, the seeds are conveniently added to the seed storage box.

[0021] In summary, the present application has the following beneficial effects:

[0022] Firstly, the roller in the application rotates under the driving of the rotating motor, and the seeds in the seed storage box are adsorbed on the annular weighing sensor by the air pump, when the seeds rotate to the highest point, the electromagnetic valve is closed, the seeds are weighed by the annular weighing sensor, then the electromagnetic valve is opened to continue rotating the seeds to above the corresponding receiving barrel, the electromagnetic valve is closed, the seeds fall into the receiving barrel, the seeds with the same size and smaller mass are picked out, the worm-eaten seeds are discharged, and the excellent seeds are selected, so as to ensure the germination rate of the seeds.

[0023] Secondly, the annular weighing sensor in the application is used in cooperation with the suction pipe, the center boss of the annular weighing sensor is the detection point, the size is relatively fixed, the suction pipe can change the diameter and be connected to the center boss of the annular weighing sensor, and can adapt to different sizes of seeds, so that the use range is improved, and the diameter of the suction pipe is larger than that of the seeds, so that the seeds can be kept stable after losing the suction force at the highest point of the roller.

[0024] Thirdly, the receiving barrels in the application can be multiple, the seeds can be different in size, and the same operation can be used to count, individually weigh and grade the seeds, so that the function is rich.

[0025] Fourthly, the seed storage box in the application can store the seeds, the exhaust pipe can blow the excess seeds in the suction pipe back into the seed storage box by adjusting the angle of the air outlet nozzle when the seeds reach the highest point of the roller, so that the weighing is not affected.

In this embodiment, the receiving barrels 7 are two, of course, they can also be three or four, one of which is used to receive seeds meeting the quality requirements, and the other is used to receive seeds not meeting the quality requirements. The drum 2 is driven to rotate by the rotating motor 11, the seed storage box 3 is used to place seeds, the mounting holes 21 are adsorbed and fixed by the suction force generated by the air pump 5 when passing through the seed storage box 3, when reaching the highest point of the drum 2, the solenoid valve 42 is closed, no suction force is generated on the seeds, then the ring-shaped load cell 4 is used to weigh the seeds, the actual mass of each seed can be obtained, then the solenoid valve 42 is opened, when the seeds reach the upper side of the corresponding receiving barrel 7, the solenoid valve 42 is closed, and the seeds automatically fall into the corresponding receiving barrel 7.
