Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to a micro-area small-diameter seed precision seeding machine. Background Art

[0002] When sowing small-grain crops such as wheat and soybeans in micro-plot experiments, mechanized sowing cannot be used due to the small size of the micro-plot experimental fields. Therefore, only traditional manual spot sowing or broadcast sowing can be used. This method not only has low sowing efficiency, but also cannot be controlled as accurately as a machine. It is easy to cause confusion in the distance between adjacent seeds during sowing, so that the plants cannot be evenly dispersed, which leads to increased errors in the experimental results. In order to solve this problem, it is crucial to innovate a small machine suitable for high-efficiency and precise spot sowing in micro-plot experiments. Utility Model Content

[0003] The utility model aims to improve the accuracy of seeding and the efficiency of seeding by providing a micro-area small-particle precision seeding machine with adjustable seed spacing, which can realize precise, rapid and uniform seeding in small-scale micro-area experiments, thus saving seeding time and improving seeding accuracy and efficiency.

[0004] The utility model is realized through the following technical scheme: a micro-area small-diameter seed precision spot seeder, comprising an outer box body and a seed storage box arranged in the outer box body, the seed storage box is arranged to slide back and forth in the outer box body, the outer box body is provided with a driving mechanism for driving the seed storage box to slide, a plurality of sowing tubes are arranged side by side at the bottom of the outer box body, a plurality of seed dropping holes are arranged side by side at the bottom of the seed storage box, the plurality of seed dropping holes correspond to the plurality of sowing tubes one by one, and the sowing tubes are located on the sliding path of the dropping holes, and handles are fixedly connected to the left and right outer walls of the outer box body.

[0005] The seed storage box of this solution slides in the outer box body. During the sliding process, when the seed drop hole of the seed storage box is aligned with the sowing tube at the bottom of the outer box body, the seeds in the seed storage box fall into the sowing tube through the seed drop hole for sowing. The seed storage box closes and opens the seed drop hole during the sliding process, so that sowing can be intermittent, improving sowing efficiency. In addition, when in use, the spacing between adjacent sowing tubes can be effectively controlled to achieve fast and uniform sowing.

[0006] As an optimization, the driving mechanism includes a lead screw, a sliding nut adapted to the lead screw, and a driving motor, the lead screw is rotatably mounted on the left or right wall of the outer box body, the sliding nut is fixedly connected to the outer wall of the seed storage box, and the driving motor drives the lead screw to rotate forward and reverse. This optimization scheme drives the sliding nut adapted to slide by the rotation of the lead screw, thereby driving the sliding of the seed storage box.

[0007] As an optimization, the drive mechanism is provided on both sides of the seed storage box, and the drive motors of the two drive mechanisms rotate synchronously in the same direction. This optimization scheme drives the seed storage box to slide forward and backward synchronously through the drive mechanisms on the left and right sides, thereby enhancing the stability of the seed storage box when sliding.

[0008] As an optimization, the two handles are respectively provided with a first switch for driving the two drive motors to rotate forward synchronously and a second switch for driving the two drive motors to rotate reversely synchronously.

A first long hole is opened on the bottom plate of the seed storage box below the seed holes, and the extension direction of the first long hole is the same as the arrangement direction of the seed holes. This optimization scheme can set adjustment plate groups for seed holes with multiple different spacings. When sowing, the spacing can be adjusted by replacing different adjustment plate groups according to the sowing spacing requirements, which is convenient to use. By setting the first long hole, the seed holes with different spacings can be aligned with the sowing tube.

[0010] As an optimization, a mounting seat is detachably mounted on the bottom of the outer box body, a placement slot is provided on the top of the mounting seat, the adjustment plate group is also laid in the placement slot, the seeding hole is a threaded hole, the upper end of the sowing tube is screwed on the drop hole, and a second long hole is provided at the bottom of the placement slot for a number of sowing tubes to pass through, and the extension direction of the second long hole is the same as the arrangement direction of the sowing tubes. This optimization scheme screws a number of sowing tubes directly onto a number of seeding holes of the adjustment plate group, so that the spacing of the sowing tubes is the same as the spacing of the seeding holes, which facilitates the alignment of the seeding holes and the sowing tubes. When it is necessary to replace the adjustment plate group with different seeding hole spacings, the sowing tube is screwed onto the corresponding adjustment plate group to complete the corresponding adjustment of the sowing tube spacing, which is easy to operate.

[0011] As an optimization, the outer diameter of the adjustment plate group is adapted to the inner diameter of the seed storage box, and the adjustment plate group includes a plurality of partitions and a plurality of orifice plates, which are arranged at intervals, and each orifice plate is provided with a seed drop hole. In this optimization scheme, the adjustment plate group is adapted to the inner diameter of the seed storage box to prevent the adjustment plate group from shaking, causing the seed drop hole and the sowing tube to be misaligned. When adjusting the spacing of the seed drop holes, the adjustment plate group can adjust the sequence of the orifice plates and partitions, or replace the combination of partitions and orifice plates of different sizes, so as to complete the adjustment of the spacing of the seed drop holes, which is convenient to use.

[0012] As an optimization, the bottom ends of the several sowing tubes are all provided with a sowing nozzle, and the sowing nozzle includes a fixed part fixed to the bottom end of the sowing tube and a movable part hinged to the bottom end of the sowing tube, the movable part and the fixed part are closed to form a conical sowing nozzle, and a lifting mechanism for driving the movable part to open is provided on the outer box. This optimization scheme facilitates the seeds to penetrate deeply into the soil by providing the sowing nozzle, and prevents the soil from blocking the sowing tube port during sowing.

[0013] As an optimization, the lifting mechanism drives the movable parts of the plurality of inserting nozzles to move synchronously. This optimization scheme is convenient for personnel to operate and improves the convenience of use.

[0014] As an optimization, the lifting mechanism includes a horizontal linkage rod, which extends along the arrangement direction of the sowing tubes, and is hinged with a plurality of vertical connecting rods, which correspond to the plurality of sowing tubes one by one, and the lower end of the connecting rod is movably connected to the movable part of the sowing nozzle, and the left and right sides of the outer box are provided with lifting rods for lifting the linkage rod upward, and the lower end of the lifting rod is connected to the linkage rod.

The seed storage box closes and opens the seed drop hole during the sliding process, so that sowing can be performed intermittently, thereby improving sowing efficiency. In addition, when in use, the spacing between adjacent sowing tubes can be effectively controlled, so as to achieve rapid and uniform sowing.

[0016] The bottom of the seed storage box and the outer box body is set by the adjustment plate group. When sowing, according to the sowing spacing requirements, the spacing of the seed holes can be adjusted by replacing different adjustment plate groups, which is easy to use.
