Abstract: A method for micro-ridge mixed-sowing cultivation of rice includes: S1: draining away water at the maturity stage of the preceding crop until reaching a state allowing a harvester to operate; S2: harvesting the preceding crop, leaving the stubble, smashing the stalks of the preceding crop, and then spreading the smashed stalks on the stubble to form a rhizosphere layer for rice growth; S3: trenching the field to form ecological trenches; S4: flattening the standing stubble and the smashed stalks on the seedbed surface to form an underlying surface, molding seed-fertilizer-soil compounds into a ridge shape and fall the seed-fertilizer-soil compounds on the underlying surface to form ecological ridges, wherein a plurality of ecological ridges are formed between adjacent ecological trenches, and the seed-fertilizer-soil compounds are obtained by thoroughly mixing rice seeds, chemical fertilizers and soil at a mass ratio of 6 to 14:50 to 70:6,000 to 10,000.

Abstract: A fluid control system for supplying fluid to multiple actuators associated with different implements disposed on an agricultural planter row unit. A first one of the multiple actuators is associated with a first implement disposed on the agricultural planter row unit. A second one of the multiple actuators is associated with a second implement disposed on the agricultural planter row unit. The fluid control system controls fluid flow from a fluid source to each of the first and second actuators. In one embodiment, the fluid control system includes an inlet valve, an outlet valve and a pressure sensor, wherein the inlet valve is in fluid communication with the fluid source and the pressure sensor is disposed to measure fluid pressure in a fluid line in fluid communication with the inlet valve and each of the first and second actuators.

Abstract: A row unit closing wheel assembly includes a closing wheel, a closing wheel arm, and a closing wheel shaft having a first end and a second end. The closing wheel is coupled to the first end and the closing wheel arm is coupled to the second end via a pivot joint. The row unit closing wheel assembly includes an adjustable mechanical assembly disposed at the pivot joint. The adjustable mechanical assembly is configured to adjust an angle of the closing wheel shaft relative to the closing wheel arm along a horizontal plane via movement of the closing wheel shaft about the pivot joint, the horizontal plane being orthogonal to a rotational axis of the pivot joint. The adjustable mechanical assembly includes interlocking teeth and is configured to utilize the interlocking teeth to adjust the angle.

Abstract: Agricultural seed planting systems include a processing unit, a frame, a furrow opener coupled to the frame for opening a furrow in soil, and a sensor in communication with the processing unit and adapted to sense a characteristic associated with seed planting. The sensor may generate a signal associated with the sensed characteristic and the processing unit may receive the signal. In some aspects, the sensed characteristic may be either a soil characteristic or a seed characteristic. Information associated with the sensed characteristic can be saved in memory for future use and to assist with more effective planting in the future.

Abstract: A soil opener includes a support and a soil opener unit. The soil opener unit comprises: first and second soil-cutting members; and a delivery tube with an exit aperture for releasing material to be deposited in the soil. The first soil-cutting member comprises a rotating disc having a first soil-engaging surface inclined: at a first angle to a perpendicular to the soil surface; and at a second angle to the direction of travel, whereby the rotating disc defines a leading upwardly inclined face defining a leading side of the rotating disc and a trailing downwardly-inclined face defining a trailing side of the rotating disc. The second soil-cutting member comprises a fixed blade defining a second soil-engaging surface. The second soil-engaging surface comprises a soil-lifting surface projecting laterally relative to the first soil-cutting member, and the exit aperture of the delivery tube is provided adjacent a rear part of the soil-lifting surface.

Abstract: A singulating meter includes a seed disc with seed apertures rotates in a vertical plane through a seed reservoir. A horizontal seed tube has an inlet adjacent to the top of the seed disc and the seed apertures move along a seed aperture path toward the inlet. Pressurized air flows into the tube inlet, and through each seed aperture as it rotates upward out of the seed reservoir pushing a seed into each seed aperture which seed then moves along the seed aperture path through about 180 degrees of rotation to a release position at the top of the path where the seed is carried horizontally into the seed tube. An ejector pushes debris out of the seed apertures into the seed tube. An alignment guide moves the singulator element of the meter into the operating position where same is magnetically secured.
