An oscillatory separation device comprises a base, an elastic support, a shell assembly, a screen mesh, a discharge port and an opening element, one end of the support is disposed on the base, the shell has first and second spaces communicating with each other and capable of accommodating a sieved object, a lower part of the shell is combined with another end of the support, the screen mesh is placed in the shell to separate the first and second spaces, and is detachably assembled with the shell, the discharge port is formed on an outer circumference of the shell and communicates with the first space, so that the sieved object can be discharged externally through the discharge port, the opening element is disposed on the shell and communicates with the first and second spaces, and the sieved object is thrown into the shell through the opening element.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

Disclosed embodiments include a screen deck assembly that can be mounted on a vibratory screening machine. The screen deck assembly includes a plurality of elongated support members that extend in a first direction. A plurality of support rods are mounted to the elongated support members. The support members and support rods form a screen support surface. The support rods extend in a direction that is transverse to the support members.

A plant product extraction apparatus or extractor is provided for separating or grading fine particles from a larger portion of material, such as separating trichomes from a stalk or flower of a plant. The apparatus imparts a plurality modes or patterns of oscillations and vibrations to a particle separator or sieve that holds the plant matter. A motor drives a back and forth motion to a support platform supporting a sieve. The sieve is constrained by a retention tray that is supported by the support platform. One or more vibratory motors provide rapid shaking vibration through the retention tray to the sieve. A haptic transducer or mechanical agitators may be provided to increase throughput of the apparatus. The various motors and locomotion patterns facilitate the separation of finer plant materials from a larger portion of a plant.
