  • Patent number: 11104562
    Abstract: Disclosed is an automatic anti-roll system and method for mobile elevator under various working conditions, related to the field of vehicle equipment. The automatic anti-roll system includes a control system, a sensing module, a driving anti-roll module, an air-operation anti-roll module and a small movement anti-roll module. The automatic response to the different manual operations to the mobile elevator is combined with automatic decision based on state sensing of the mobile elevator to realize the automatic judgment and anti-roll control for different working conditions. As a result, the active-passive combined anti-roll control can be realized for various working conditions in various complicated environments such as driving, aerial operations, and small movement. The anti-roll system has a simple structure and can be operated easily. All the advantages make this system and method meet the practical requirements of anti-roll protection for all working conditions of the mobile elevator.

  • Publication number: 20200267911
    Abstract: A full-automatic system and operation method of integrated sorting-transplanting-replanting for plug seedlings includes a frame, feeding units for a target tray and source tray, a discarding seedling tray bin, a single-claw for replanting unit, a multi-claw for sorting and transplanting unit, seedling picking claws and a monitoring module. During transportation, the seedling picking claws pass through a seedling picking zone, seedling monitoring zone, seedling discarding zone and seedling releasing zone in turn. The monitoring module and the single-claw for replanting unit are located behind and in the front of the vertical movement plane of the multi-claw, respectively. Along a tray feeding direction, a first row of the source tray is set as a source area for replanting, and other rows of the source tray are all set as the source area for transplanting. The monitoring and sorting is finished during the transportation without stopping.

  • Patent number: 10334790
    Abstract: The invention presents technology for elevated cultivation comprising an automatic paver and man-machine collaboration matrix control method in the field of agricultural equipment. The substrate auto-paver for the table-top culture machine is mainly composed of a moving car, a matrix and a matrix-packing mechanism, the substrate material in the cabinet, an evenly paving mechanism that realizes double-sided blanking, and a remote control. The manual push-pull arm is employed to ensure that the return wheel touches the ground, using the matrix agencies to van automatically. The remote control is used to move the car into the elevated inter-row cultivation bed, and then, the double-sided blanking and evenly paving mechanism is automatically activated until the track wheel falls into the slot on the skeleton. By means of the bending type of chain transmission mechanism, the soilless culture substrates are automatically conveyed owing to the bilateral symmetry of blanking trough.
