Abstract

The chemical transfer and handling cart for chemical containers consists of three main parts: the movement unit, the lifting and rotating unit, and the chemical transfer unit. The movement unit moves the chemical container and provides support, preventing tilting during lifting and rotating. The lifting and rotating unit is designed with arms to grip the container. Once gripped, a hydraulic cylinder lifts the container, and a motor rotates it to invert it. The chemical transfer unit transfers the chemical from the container according to the required weight, using compressed air to push the chemical. This invented chemical transfer and handling cart allows for convenient and rapid movement and transfer of chemical containers for various applications, reducing labor costs and allowing for precise control of the chemical transfer weight.

Claims (1)

1. The chemical transfer and handling cart for chemical containers consists of a drive unit, a drum lifting and rotating unit, and a chemical transfer unit. Its specific characteristics are as follows: The drum lifting and rotating unit consists of a drum clamp, a drum lifting unit, and a drum rotating unit. The drum clamp has the form of arms (5) both upper and lower, which serve to hold the drum securely to the cart. One end of the arm is attached to the cart, with a hinge (6) allowing the arm (5) to move open and close together. The other end of the arm (5) has a hinge and a threaded rod (7) to hold the drum, and the thread is adjustable. The end of the threaded rod (7) has a hole that can be fitted into the other end, which has a hole for a locking pin (8). A handle (9) is used to easily push the two arms (5) together. The drum is held in place by both the upper and lower arms, preventing it from falling off when lifted or rotated. The base of the lower arm (5) is made of a thin sheet of steel (10) to support the base of the drum. The vertical threaded rod (11) is adjustable according to the height of the drum. On the rear end of the arm where the locking pin (8) is inserted, a sensor (12) is installed, which checks for the insertion of the locking pin (8) to activate the lifting and rotating assembly. The lifting assembly consists of a hydraulic piston (13) that is positioned vertically, with a chain and sprocket assembly (14) at its end. One end of the chain is attached to a weight sensor (15), and the other end to the drum clamp. The hydraulic piston (13) moves the drum up and down, and a sensor (16) detects the position at which the drum is raised or lowered. This hydraulic piston (13) can be controlled either automatically via programming or directly via a lever (17). The rotating assembly consists of a motor (18) and a gearbox (19) connected to the drum clamp via a chain and a flat disc sprocket (20), which allows the drum to rotate up and down, and a sensor (21) indicates the range of rotation of the drum. The chemical transfer assembly consists of a drum lid (22), which replaces the original lid of the chemical container. It consists of a chemical control valve (23) which opens to control the flow of chemicals through the chemical delivery port (24) and an air hose port (25) which helps push the chemicals to higher and further containers more quickly. The weight of the chemicals is measured by a weight sensor (15). Once the desired weight of chemicals has been transferred, the controller automatically closes the valve (23). A water control valve (26) opens and closes the flow of water through the water delivery port (27) to the chemical delivery port (24) to allow water to flow in and clean the connected chemical delivery lines. The user interface consists of an on/off switch (28), an emergency button (29) that immediately stops the vehicle, a battery voltage display (30), and a touch screen (31) which controls the operation and can be operated manually or automatically.
