Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a rice dry-planting machine. Background Technology

[0002] For many years, rice cultivation has relied on seedling raising and transplanting to increase yields, with occasional but less common practice of direct seeding. While seedling raising and transplanting results in high yields and early maturity, it is labor-intensive, with a short seedling-raising and transplanting period and a large workload. Direct seeding using dry-seeding methods is labor-saving, requires less land preparation and other agricultural operations, and is highly adaptable. Currently, most dry-seeding machines used by farmers are relatively simple; although they can complete dry seeding, they are often less than ideal, resulting in low cultivation quality and affecting yield, thus impacting the annual or single-season rice production. Therefore, this utility model was designed to address this issue. Summary of the Invention

[0003] The purpose of this utility model is to provide a dry rice planter. In view of the above-mentioned drawbacks, this utility model has the advantages of saving labor and time, and has a compact mechanical structure, reasonable design, flexible and convenient adjustment, and strong adaptability.

[0004] To achieve the above objectives, the technical solution of this utility model is a rice dryland planter, comprising: a frame, a seed and fertilizer box, a ground working roller, a gearbox, a traction frame, a feeder, a feed inlet, a feed pipe, a feed adjustment gear, an adjustment and locking handle, a seed and fertilizer box motor, a seed and fertilizer box gear, and a power transmission mechanism. The frame is composed of side plates and crossbeams, with crossbeams fixedly connected inside the side plates. A seed and fertilizer box is installed on the upper part of the frame, consisting of a fertilizer box, a diamine box, a seedling strengthening agent box, and a seed box, arranged sequentially from front to back. Each box has a leakage hole at its bottom, and a feeder is correspondingly installed below the leakage hole. A feed pipe is connected below the feeder and inserted into the feed inlet, which is located behind the ridge forming roller. A feed adjustment gear is installed inside the feeder, and the feed adjustment gear is connected to a through shaft. The machine is connected to the side plate. One end of the shaft extends beyond the side plate and is equipped with an adjustment and locking handle. The other end is equipped with a seed and fertilizer box gear, which is connected to the seed and fertilizer box motor via a chain. A traction frame is set at the front of the frame, and a ground working roller is set at the lower part of the frame. The ground working roller includes a harrow blade, a rotary tillage roller, a ridge forming roller, and a backfilling roller. A backfilling shovel is set axially on the backfilling roller, and the backfilling shovel is set on both sides of the material feeding port. A gearbox is set in the middle of the frame. The gearbox is adapted to the rotary tillage roller and the ridge forming roller. The ridge forming roller consists of a spacer sleeve, an end gap sleeve, a locking nut, and a ridge forming roller shaft. The spacer sleeve is available in two lengths. Adjusting the spacer sleeve configuration can adjust the ridge spacing to meet production needs. Locking nuts are set on both sides of the ridge forming roller shaft.

[0005] A movable side plate is provided on the outer side of the side plate. The movable side plate is connected to the backing roller through a bearing. The movable side plate moves up and down in an arc shape with the ridge forming roller as the axis, and the height of the backing roller is adjusted by an adjusting screw.

[0006] A retaining plate is installed behind the backing roller. The retaining plate can block soil and dust, and can also smooth the surface soil after backing.

[0007] The backfill shovel has three blades evenly distributed.

[0008] A foot pedal is provided at the rear of the frame.

[0009] The height of each outlet of the fabric opening from the ground is h1 < h2 < h3, with h1 being 15 cm above the ground and h2 and h3 being slightly higher in that order.

[0010] The power transmission mechanism comprises two parts: one part is transmitted through a gearbox, and the other part is transmitted through a seed and fertilizer box motor. The gearbox transmits power to the ridge forming roller, which is connected to the backfilling roller via a sprocket. The other output end of the gearbox transmits power to the rotary tillage roller. The seed and fertilizer box motor transmits power to the material distribution adjustment gear under the seed and fertilizer box via the seed and fertilizer box gear.

[0011] The beneficial effects of this utility model are: 1. The soil scooped up by the soil shovel will splash in the direction of the arrow. After landing, the soil will be leveled by the retaining board, which can also retain soil. 2. The ridge forming roller used consists of a spacer sleeve, an end gap sleeve, a locking nut, and a ridge forming roller shaft. The spacer sleeve is available in two lengths to adjust the ridge spacing to meet production needs. 3. The movable side plate is used. The movable side plate moves up and down in an arc shape with the ridge forming roller as the axis, which can adjust the height of the backing roller. 4. The height of each outlet from the ground is h1 < h2 < h3, which allows the fertilizer to be layered and released at different times. 5. The power transmission mechanism consists of two parts: one part is transmitted through a gearbox, and the other part is transmitted through a seed and fertilizer box motor. The gearbox transmits power to the ridge forming roller, which is connected to the backfilling roller through a sprocket. The other output end of the gearbox transmits power to the rotary tillage roller. The seed and fertilizer box motor transmits power to the material distribution adjustment gear under the seed and fertilizer box through a sprocket. 6. This utility model has the characteristics of reasonable design structure, high reliability, low failure rate, saving labor, time and effort, flexible and convenient adjustment, and wide adaptability. It is a good helper for farmers to grow rice.
