A pneumatic distribution system for distributing a granular product to an agricultural implement includes a first pressure sensor, a second pressure sensor, a valve, and a controller. The first pressure sensor is fluidly coupled to a storage tank that stores the granular product and outputs a first signal indicative of a first static pressure in the storage tank. The second pressure sensor is fluidly coupled to a meter housing and outputs a second signal indicative of a second static pressure in the meter housing. The valve is fluidly coupled between the storage tank and the primary line and selectively enables the air stream to flow from the primary line to the storage tank. The controller is communicatively coupled to the first pressure sensor, to the second pressure sensor, and to the valve. The controller instructs the valve to enable the air stream to flow from the primary line into the storage tank until the first static pressure is greater than the second static pressure by a threshold amount.

A method for controlling product distribution in an agricultural product distribution system, including monitoring, using a processor, a first static pressure in a storage tank that stores a granular product, monitoring, using the processor, a second static pressure in a meter housing, downstream of a meter roller; and controlling, using the processor, a position of a valve on a secondary line to adjust the first static pressure to a value above the second static pressure by a threshold amount, wherein the secondary line is fluidly coupled between the storage tank and a primary line that pneumatically delivers the granular product to an agricultural implement.

A pneumatic distribution system to distribute a granular product to an agricultural implement includes a valve assembly fluidly coupled between a storage tank and a primary line. The storage tank is configured to store the granular product. The primary line is configured to pneumatically deliver the granular product to the agricultural implement by guiding an air stream from a first section of the primary line with a larger cross sectional area to a second section of the primary line with a smaller cross sectional area. The valve assembly selectively enables the air stream to flow from the primary line into the storage tank until a first static pressure in the storage tank is greater than a second static pressure in the second section of the primary line by a threshold amount.

An injection mixer is provided, which includes an injection module, a valve seat module, and an adjusting module. The injection module may be disposed to penetrate one end of a bucket container. The valve seat module may be disposed at the end of the injection module, and the valve seat module may be disposed with at least one fluid supply channel and at least one outlet channel. The adjusting module may be disposed at the valve seat module to penetrate therethrough. The adjusting module may be movably connected to the injection module. When the adjusting module is driven to move the injection module towards or away from the valve seat module, an annular protrusion may approach or move away from the inner wall of the bucket container, and a size of the predetermined gap may be reduced or increased.

A pressurized tank is provided in which no air flows back from a piping for conveying powder to the pressurized tank. A pressurized tank (A) is used for a device (B) for intermittently feeding a predetermined amount of powder to a piping (7) for conveying the powder when the powder is conveyed in a plug flow through the piping (7) by means of compressed air. The tank (A) has a first pressurized room (6) that is a pressure vessel and that has a funnel-shaped upper partition (3) that has an opening and a funnel-shaped lower partition (4) that also has an opening, a first check valve (9) that is provided beneath the opening of the upper partition (3) of the first pressurized room (6) and is vertically moved so as to be upwardly moved by means of compressed air to close the opening of the upper partition (3), a second check valve (10) that is provided beneath the opening of the lower partition (4) of the first pressurized room (6) and is vertically moved so as to be upwardly moved by means of compressed air to close the opening of the lower partition (4), and an elastic body (24) to upwardly bias the second check valve (10).
