Abstract: A seeding machine has a common, bulk seed container that supplies a number of independent openers, each of which is provided with its own separate metering device. Each metering device is gravity-fed through a telescoping supply tube connected between the top of the metering device and the bottom of the seed container. Each metering device has a relative narrow metering wheel rotatable about a transverse horizontal axis that is provided with one or more rows of seed pockets on its outermost peripheral edge. As the wheel rotates upwardly through a pool of incoming seeds that have collected generally above the wheel in a seed chamber inside the metering device, the pockets become filled by gravity with seeds and then succesively discharged at the bottom of the downsweep side of the wheel. Spring-loaded retaining structure along the downsweep side of the wheel keeps the seeds within their respective pockets unitl the pockets reach the discharge outlet at the bottom of the meter, whereupon the seeds gravitate freely from the wheel in succession and are directed to the ground.

Abstract: A seed metering device (10) for agricultural seeders has a meter housing (17), a seed disk (22) covering an open side of the meter housing (17), and a brush assembly(27) mounted within the meter housing (17) and contacting the seed disk (22). The meter housing (17) has a seed delivery opening (19) for delivering a supply of seed into a seed pool area (20), an air inlet (26) provided above the seed pool (20) area for receiving a supply of positive pressure air into the meter housing (17), and a seed exit area (31) where seed can be dropped into a seed tube (15). The seed disk (22) has seed pockets (23) spaced around its outer circumference that pass through the seed pool (20) and pick up individual seeds as the seed disk (22) rotates. The device (10) includes several features that help singulate and drop seeds in a way that provides a desired number of seeds per acre and a uniform spacing between the seeds in the furrow.

Abstract: An agricultural seeding implement has a seed hopper that is weighed continuously during field operations as the seed volume in the hopper progressively diminishes. The weight information is used to perform ongoing control functions on the implement. One embodiment uses the weight information to reduce the down pressure on compaction wheels of a wing section of the machine as a function of the diminishing weight of the hopper on the main section.

Abstract: A standardized receiver for bulk materials containers such as seeds for the quick and efficient loading of seed into a planter with bulk handling capability. Delivery mechanism associated with the receiver is disposed to accept materials discharged from the container after it has been placed on the planter frame and to transport such materials to the opener rows. A manifold of the mechanism is fitted with output pipe fixtures for the discharge of the seed to individual rows via flexible hose. The inlet of the manifold is on the top surface of the structure and aligned with the slidegate opening of the shipping container. Air pressure is created within the manifold by a fan assembly. Airflow exiting the manifold carries seed through the pipe fittings, into the hoses and on to the planter rows.

Abstract: The seed distribution tower of an air seeder splits a single, primary stream of conveying air and seeds into a plurality of secondary streams for delivery to openers that deposit the seeds into the ground as the seeder advances. As seeds enter the head of the tower in an upward vertical direction through an inlet at the bottom of the head, they are scattered 360° in a horizontal direction by an inverted, overhead distribution cone. The inlet through which the seeds enter the distribution head has an eased configuration to reduce turbulence and promote laminar flow within the head during the dramatic transition from vertical to horizontal movement. Sensitive components such as tram line valves, solenoid actuators, and blockage sensors are protectively housed within the interior of the distribution head to avoid exposure to hostile environmental elements. The outlets through which the secondary streams exit the head are constructed as modules that can be individually installed and replaced without disassembling the entire head. Shut-off valves and/or flow sensors may or may not be incorporated into certain or all of the modules to provide optimum user flexibility.

Abstract: When the operator of a cultivation air seeder shifts the tractor valve to raise the cultivators and openers from the ground as the seeder prepares to turn around at the end of a field, the operating and control system of the seeder causes the cultivators to be raised first, followed in sequence by the trailing openers. The seed meter turns off as soon as the cultivators leave their lowered position, but the blower stays on so that seeds in the conduits downstream from the meter continue to be delivered to and deposited into the ground by the openers until the cultivators reach their raised position, whereupon the openers are raised. Depending upon the particular seeding mode selected by the operator, the cultivators and openers either lower simultaneously as the operator shifts the tractor valve to the lowering position when starting down the next pass, or the cultivators are lowered first, followed in sequence by the openers. Regardless of the selected seeding mode, the seed meter turns on as soon as the cultivators reach their lowered positions.

Abstract translation: 当种植播种机的操作人员移动拖拉机阀门以在播种机准备在田地结束时转动时将耕作机和开放机从地面上升起，播种机的操作和控制系统使得耕耘机先升起 ，其次是尾随开启者。 一旦种植者离开他们的下降位置，种子计就关闭，但鼓风机保持打开状态，使得从仪表下游的导管中的种子继续被开放器输送并沉积到地面中，直到耕作机达到其升高位置 因此，开放者被提升。 根据操作人员选择的特定种子方式，当下一次开始下降时，操作人员将拖拉机阀移动到下降位置，或者耕耘机首先被降低，随后由打开机依次降低，耕耘机和打开机构同时下降。 无论选择种子播种方式如何，播种机到达降低位置后，种子计开启。

Abstract: A cultivation air seeder has an ornamental facing around three sides of its large, metallic bulk seed hopper to enhance the appearance of the hopper and provide environmental protection for sensitive mechanical, electronic and hydraulic components. A front section of one facing panel on each side of the machine is hinged about a generally upright axis to allow the panel section to be opened and closed like a door for operator access to the components behind it. The facing can be stylishly molded from a synthetic resinous material or other non-metallic substance to facilitate manufacture and is disposed to conceal unslightly weld lines and other imperfections on the exterior surface of the hopper.

Abstract: To produce, monitor, and control a flow of air for a seed conveying system and a seed metering system, an air-assisted planting system includes an air handling system having a single air source and an air controller for maintaining a generally constant air pressure to the metering system. The air controller includes a plurality of sensors associated with and operable to monitor an air pressure through the metering system. Based on a sensed air pressure, a microprocessor of the air controller instructs the air handling system to selectively divert the flow of air to the metering system on an as-needed basis to maintain the generally constant air pressure.
