Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Six adjacent seed funnel boxes 2 are installed on the frame 1 top, and the bottom of each seed funnel box 2 has a bottom opening. The lower end of the particle flow regulating plate 7 is covered with a rubber sleeve 12 . The seed flow regulating plate 7 is fixed on the side plate of the seed funnel box 2 with the adjusting screw 6, and the seed flow regulating plate 7 has a moving groove. The two ends of the rotating shaft 4 are supported and fixed on the both sides of the frame 1 through the bearing support. One end of the rotating shaft 4 stretches out from the frame 1, and the distance between plants control wheel 5 is housed at its shaft end. Turning wheel, when it forwards to vertical position, the blade below should surpass the boat-shaped flat dragging plate 8 of frame 1 bottom. Six sowing collars 3 are set on the rotating shaft 4 shafts, and the outer peripheral wall of each sowing collar 3 stretches into the bottom opening of the seed funnel box 2 at the corresponding position above, and the front side plate of the sowing collar 3 and the seed funnel box 2 There is a slit 13 at the bottom mouth position, which is used to leak rice seeds. Four seed filling pits 11 are evenly distributed on the peripheral wall of each sowing collar 3 . The sowing collar 3 can be press-fitted on the rotating shaft 4 in a tight fit mode (seeing accompanying drawing 4), and can also be fixed on the rotating shaft 4 through the sowing collar 3 from a seed pit with a set screw 17 (seeing the accompanying drawing). 6). The distance between two adjacent sowing collars 3 for loading seed pits 11 is determined by the row spacing of the two rows required for sowing, and the distance between the adjacent two seed pits 11 on the sowing collar 3 is also determined by the sowing requirements. The distance between the two pockets in the row is determined. Therefore, the row spacing and the pocket spacing of the sowing technology requirements determine the spacing of the sowing collar 3 and the number of seed pits. The upper end of the leaking seed chute 10 is packaged on the front side plate of the seed hopper 2 at the bottom of the seed hopper 2, and the seed chute 10 is obliquely bent downward below the bottom of the seed hopper 2. Stretch out outside the chassis of frame 1 backward (see accompanying drawing 4). The bottom of frame 1 is equipped with boat-shaped flat carriage 8 (seeing accompanying drawing 1, accompanying drawing 4). Four balance boards 9 (seeing accompanying drawing 2, accompanying drawing 4) stretching out behind the machine are housed below boat shape flat dragging plate 8. Its distribution requirements are generally considered to have a balance board 9 at intervals of two sowing collars 3. One of its functions is to prevent the balance of the body from tilting to the rear side when it is pulled forward. 9. Because the weight of the body is pressed in the wet mud, the concave row pit is pressed out during the forward movement, which is beneficial for the surface water of the field to flow into the pit, so that the sowing seeds are not soaked in water, which is conducive to germination and growth. Screw 18 is fixedly equipped with pull bar axle seat 15 at ship shape flat dragging plate 8 midsection positions, and the pull bar axle 16 of pull bar 14 is supported in pull bar axle seat 15 axle holes. The 8 effects of boat-shaped flat dragging plate are: support body weight, do not make body sink in the wet mud of paddy field, in addition, also have before planting again suitable smooth paddy field wet mud surface, help uniform sowing.

How many rows are required to be once sown by the direct seeding of rice seed determines the size of the machine, that is, the quantity of the seed funnel box 2 and the sowing collar 3 can be six or more than six, and their quantity will be corresponding. The present embodiment selects six respectively.

The number of the seed pits 11 of the sowing collar 3 is determined by the distance between two adjacent rows in the row of the direct seeding rice seed, which can be four or more, and the present embodiment selects four.

The rice seed direct seeding machine is mainly composed of a frame 1, a seed funnel box 2, a sowing collar 3, a seed flow regulating plate 7, a boat-shaped flat drag plate 8, a seed leakage groove plate 10, a rotating shaft 4, a distance control wheel 5, and a balance Plate 9 and pull bar 14 are combined to form, and it is made with metal material, aluminum-plastic plate, plastic rod. This rice seed direct seeding machine is a machine tool for direct seeding of rice seeds. When in use, put the rice seeds to be direct seeded in the seed funnel box 2, adjust the seed flow regulating plate 7 to select a suitable size of the slot hole 13, and drag it by a person. Pull bar 14 advances, and rice seed direct seeding machine advances along with, and the blade of plant spacing control wheel 5 sinks in wet mud, drives rotating shaft 4 and sowing collar 3 to rotate when plant spacing control wheel 5 rotates, and the seed grain in the seed grain pit 11 is packed with The sowing collar 3 rotates and rotates downward to shift, and when it reaches the slit 13, it is scratched by the rubber sleeve 12 at the lower end of the seed flow regulating plate 7 (the rubber sleeve 12 is to prevent the seed bud tip from being scratched when scratching and blocking redundant seeds. ), the seed in the seed pit 11 moves through the slit 13 and falls into the leaking seed trough 10, and under the action of gravity, the seed slides down along the leaking seed trough 10 and falls to the wet surface of the paddy field. On the mud, the seeding collar 3 is continuously operated, and the seed grains are continuously broadcast on the wet mud of the paddy field according to the requirements, so that the row spacing and spacing are broadcasted according to the requirements.

The rice seed direct seeding machine in this embodiment is a six-row machine with a width of 1.2 meters, a row spacing of 20 centimeters, and a plant spacing of 17 centimeters. It is manually dragged and sowed, sowing 2 to 2.5 acres per hour, the weight of the whole machine is about 10 kilograms, and the service life is 5 to 8. In 2009, the loss rate of rice seeds was below 2%, and the rate of seedling growth was over 98% under the condition that the fields were leveled and the seedlings were completely broken.

This machine can be used for direct seeding of early rice and late rice. It is low in cost, easy to use, easy to maintain, light in labor intensity, and saves seedling raising fields. The utilization rate of rice fields is 100%. The process of manual labor such as transplanting or throwing seedlings, and direct seeding grows better than seedlings raised, transplanted or thrown, and the output increases by about 20%, which is 15 times more effective than traditional manual transplanting, and 5 times more effective than throwing seedlings above.
