Description

Technical field[0001]The present invention relates to the field of agricultural machinery, and more particularly to a cone vibration high speed queuing selection apparatus and method.Background technique[0002]In the production of crop production, mechanized sowing is an important means of high-efficiency operation and standardization operations in modern agriculture. The crater device is a key component for controlling the amount of sowing and its accuracy, which is critical to ensuring the quality of the operation and achieving accurate operations. In particular, in the mechanized seedling operation of rice seeds, due to the large rice variety, the physical properties of different varieties and rice species are different, such as the optimum accuracy of hybrid rice seeds is 2-3 capsules, so When designing the sowing device, it is necessary to fully consider the adaptability of rice species of different varieties to meet the needs of rice species of different varieties.[0003]At pres...

Problems solved by technology

The device is mainly used for small smooth seeds and other materials. Different sizes of seeds need to be equipped with different sizes of grinding discs, which increases the complexity of accessories manufacturing, matching, use and storage. It is difficult to achieve single-grain, continuous, and queuing. , in addition, the seed breakage rate is higher

[0009] The pneumatic seeding device uses the large-diameter seeding wheel at the bottom of the seed box to send the seeds into the airflow pipe, and the seeds are transported to the distributor by the airflow in the pipe, and then enter the seed ditch through the airflow seeding pipe. The device is more uniform in seeding , low seed damage rate, but complex structure, high manufacturing precision requirements

[0010] In the above-mentioned prior art, to realize displacement control in the seeding process, most of them use rotating parts, and the following problems mainly exist in the control of the rotating parts: 1) pulsation phenomenon inevitably occurs in the seeding process, which affects the continuity and uniformity of the seeds ; 2) The overlapping rate of the discharged seed particles is high, and the effect of single seed queuing is not good; 3) When the rotational speed of the rotating parts is too high, it is easy to appear the phenomenon that the seeds cannot be filled, so it is difficult to realize high-speed seeding; 4) The seeds are in the In contact with rotating parts, interactions such as rolling and friction are prone to occur, and the seed damage rate is high; 5) The seeds are easy to arch in the seed box or pipeline and cause blockage, and the device lacks the function of self-breaking arch; 6) The device The structure is complex, when there is an arch blockage or when cleaning is required after the work is completed, the disassembly workload is large

[0013] The existing vibration queuing seeding technology can realize orderly queuing and sowing, but there are the following deficiencies: 1) a longer vibration distance is required to gradually realize seed queuing, and the seed queuing time is long; 2) the effect of single seed queuing is not good, The smaller the seeds, the worse the seeding effect of queuing; 3) The seeding effect of irregular seeds is not ideal, prone to arching, and the seeding speed is not high enough; 4) The arching cannot be broken by itself after arching, which is easy to cause blockage; 5) Queuing The structure of the device is complex, and the size is large, requiring a large installation space; 6) It is difficult to apply under field conditions that require high real-time and high-efficiency operations

The existing vibrating arch-breaking technology is mainly used for arch-breaking of large and medium-sized equipment such as granaries. The discharge volume is large, and it is not suitable for single-grain high-speed queuing and discharging.
