The disclosure discloses an apparatus for online volumetrically detecting grain yield based on weight calibration comprising left volumetric granary, right volumetric granary and push board. The left volumetric granary is provided on its bottom with first weighing sensor, and in its side with unload grain port opening and first closing door, the right volumetric granary is provided on its bottom with second weighing sensor, and in its side with unload grain port opening and second closing door, the left volumetric granary and the right volumetric granary are provided on their tops with the push board, the push board is a hollow box structure with a top side and a bottom side both opened, and is slidably mounted to a top of the left volumetric granary and the right volumetric granary through a slide driving mechanism.

Provided is a silo hopper with a hopper opening for connection to a silo cell with a rectangular cross-section. The silo hopper includes a hopper wall which encloses the hopper opening. The hopper wall extends from an upper plane to a lower plane lying parallel thereto and tapers from a rectangular upper cross-section in the upper plane to a smaller lower cross-section in the lower plane. The silo hopper is self-supporting and is provided at at least one corner, preferably at all corners, with a leg segment. The leg segment extends at right angles to the upper plane and includes a first plate part which is parallel to a first side of the upper cross-section and includes a second plate part which is parallel to a second side of the upper cross-section lying at right angles to the first side. The first and second plate parts are mutually connected close to the hopper opening by a third plate part. The third plate part forms an angle of 135 with the first and second plate part, as seen perpendicularly of the upper plane. Also provided are a silo base and a method for erecting a silo.

The hopper body has a third sidewall and a fourth sidewall that face each other in a second direction intersecting with the first direction and that connect between the first sidewall and the second sidewall, and a first corner portion adjacent to the distal end portion of the trough in the third sidewall and a second corner portion adjacent to the distal end portion of the trough in the fourth sidewall are bent in direction away from the distal end portion of the trough and also a first edge portion adjacent to the distal end portion of the trough in the first corner portion and a second edge portion adjacent to the distal end portion of the trough in the second corner portion are bent in direction closer to the distal end portion of the trough.

A bulk loader system is disclosed that may include a conveyor unit in connection with a fuel-powered engine powering a hydraulic motor. The hydraulic motor may be used to operate the conveyor unit. The system may be configured to function while being mounted on a bed of a truck or be operated as a stand-alone unit. The unit may be sized such that an operator can stand on the deck of the truck along with the unit. The fuel-hydraulic powered motor can enable the conveyor unit to operate at variable speeds. The conveyor unit can be adjustable to facilitate controlling the direction of the material being transported via the conveyor. Some embodiments can include operating the hydraulics of the motor from the Power Take-Off (PTO) of the truck. Some embodiments can facilitate operation of the system in a hot or other harsh environment.

An apparatus to support a proppant container includes a frame to receive and support the proppant container. The frame has a top surface that receives and positions the proppant container in an elevated position. The apparatus also includes a box guide assembly positioned on the top surface a box guide assembly connected to the top surface of the frame for defining a cradle section having four corners. The box guide assembly including a box guide positioned at each of the corners. Each box guide has a corner member extending upwardly from the top surface along a peripheral edge of the frame and a guide member extending adjacent the corner member. The guide member include an inclined face for aligning the proppant container in the cradle section. The box guide assembly guides the proppant container into the cradle section when loaded onto the frame in the elevated position.

The present invention is a modular system for delivering material directly to a blender hopper. The system includes primary base and optional secondary base modules supporting surge hoppers which receive material from material containers. The surge hopper may then dispense the material directly and rapidly to the blender hopper by gravity feed. During continuous operation, exhausted material containers may be removed from the surge hoppers and replaced with full material containers as material empties from the surge hoppers. This allows steady, high-volume flow of material to the blender hopper.

A container or pod is specially constructed for hauling proppant in support of oilfield hydraulic fracturing operations. Dimensions are provided that comport with common dimensions in use for transportation of intermodal containers, with the containers being sized so as not to require special permitting from a regulatory standpoint when two such containers are loaded on a single trailer. A method of filling the containers is also provided, which include inverting the container to fill from a bottom gate that also serves as the discharge opening when the filled container is rotated back into an upright position.
