Rolling Screen Or Sieve (e.g., Wheel Or Belt) Patents (Class 171/112)
  • Patent number: 11117168
    Abstract: A system for processing usable crop intermixed with debris and having a frame with a conveying system thereon. The conveying system has a first debris separating assembly with a first subframe having a plurality of cooperating rollers that are configured to cause separation of debris from the usable crop. A second debris separating assembly, different than the first debris separating assembly, has a second subframe with a plurality of cooperating rollers thereon that are configured to cause separation of debris from the usable crop. The frame and first and second debris separating assemblies are configured as overall like modules so that the first and second debris separating assemblies can be separately operatively connected, one in place of the other, on the frame.

  • Patent number: 8757391
    Abstract: A garbage separation and recovery machine for beach cleaning that has mobility and can perform a garbage separation and recovery work according to the situation is provided. The garbage separation and recovery machine has a drum type sieve body (54) that is freely rotatably secured to a vehicle body frame (51) towed by a vehicle, a driving gear (92) that is freely rotatably supported by the vehicle body frame (51) and secured to an axle (52) to which right and left wheels are secured, and a mechanism portion (91) for transmitting the driving force of the driving gear (92) to the drum type sieve body (54). The mechanism portion (91) has a gear switching mechanism (95) for performing a switching operation between an automatic rotation mode in which the drum type sieve body (54) is rotated by the rotational force of the wheels (53) and a manual rotation mode in which the drum type sieve body (54) is released from the rotational force of the wheel (53) and allowed to be manually freely rotatable.

  • Patent number: 8555530
    Abstract: An apparatus for padding a pipeline lying in a ditch separates fine particles from coarse particles in the material excavated from the ditch and windrowed along the side of the ditch. The apparatus includes a frame having an open ended hollow separating drum having a plurality of scoop members adapted to lift and drop excavated material through a screen located beneath the scoop members. The scoop members are spaced above the screen a distance such that the efficiency of the separating drum is increased.

  • Patent number: 8109342
    Abstract: A box-shaped beach-cleaning trailer is configured to be loaded with, and collectively carry beach-cleaning equipment and a litter collection station. The beach-cleaning equipment are towed by a vehicle to collect litter on the sands. The litter collected by the beach-cleaning equipment is collected in the litter collection station. The trailer includes a pair of rail members disposed on upper edges of the respective opposite side wall portions such that the rail members face each other with an opening therebetween. A sieve unit is detachably mounted on the rail members, and is configured to move a back-and-forth direction along the rail members. The sieve unit is moved in a back-and-forth direction manually; or by using a driving mechanism including a drive wheel, a driven wheel, and a connecting rod arranged between the sieve unit and the driven wheel, for separating colleted litter of various sizes from sand.

  • Patent number: 7165628
    Abstract: A harvester for root crops such as beets is provided which preferably provides continuous flow of root crops from a header, along a transfer assembly, through a processing run, and to an elevator assembly. The harvester can be configured to include or accommodate interchangeable header assemblies having different numbers of rows and/or row spacings. The transfer assembly can be of a floating type and helps to provide an even distribution of beets to the grabrollers. The processing run includes full-length cleaning grabrollers disposed parallel to the direction of travel. Modular elevator assemblies can be provided to further enhance harvester versatility. Such an approach includes interchangeable ferris wheel and scrubber chain elevator assemblies. An improved scrubber chain elevator assembly can be used which has a wraparound scrubber chain design. A pivoting tank conveyor for evenly filling a holding tank can be included.

  • Patent number: 4121667
    Abstract: A potato or other root crop harvester having a shock absorbing primary bed is disclosed. The primary bed is held in normal digging position by high pressure fluid cylinders. A shock to the shovels attached to the forward edge of the primary bed causes the fluid pressure to rise within the cylinders, thereby exceeding a relief valve setting and allowing the fluid to discharge from the cylinders to permit the primary bed to move rearwardly, absorbing the shock and preventing damage to the harvester. A further unique feature of the potato harvester is the presence of three shovels attached to the primary bed to harvest three rows simultaneously. The primary bed discharges tubers onto a secondary bed which transports them to lateral transport means to discharge them into trucks or other carriers. A devining chain encompasses the secondary bed, allowing potatoes to fall through onto the secondary bed while carrying vines to the rear of the harvester to discharge them.
