Description

Technical Field

[0001] This utility model belongs to the field of transplanter technology, and in particular relates to a cylinder mechanical control mechanism for a transplanter. Background Technology

[0002] With the continuous development of agriculture in my country, pot seedling technology has been widely used. This technology allows seedlings to effectively avoid the effects of severe weather such as low temperatures and strong winds, greatly improving the survival rate and yield of plants. However, the seedling taking device of the pot seedling transplanter currently in use is relatively complex.

[0003] The invention patent application with application number CN202210510023.1 discloses a transplanter linkage seedling picking device, including a guide seat plate, a sliding seedling claw frame, a flipping seat frame, a left sliding seat, a right sliding seat, a seedling frame drive device, a flipping drive device, and a power transmission device. The guide seat plate has linkage guide grooves on its left and right sides, and longitudinal slide rails are provided at the lower left and right ends of the guide seat plate, through which the sliding seedling claw frame is mounted. The upper middle part of the sliding seedling claw frame is fixed. The device includes a seedling rack with upright pins. The lower part of the sliding seedling claw rack is hinged to a tilting base with a transverse slide rail. A left seedling claw assembly is installed on the left side of the transverse slide rail, and a right seedling claw assembly is installed on the right side. Each of the left and right seedling claw assemblies includes at least two seedling grasping claws capable of gripping potted seedlings. A seedling rack drive device with a seedling rack drive shaft is installed at the upper end of the guide plate, and a tilting drive device with a tilting drive shaft is installed at the lower end of the guide plate. The seedling rack drive device and the tilting drive device... Each component is connected to a power transmission device. The seedling rack drive device is connected to the seedling rack upright pins and can drive the sliding seedling claw frame to move back and forth along the longitudinal slide rail. The tilting drive device is connected to the tilting seat frame and can drive the tilting seat frame to swing back and forth. A sliding horizontal rail is fixed to the rear of the sliding seedling claw frame. A left sliding seat is installed on the left side of the sliding horizontal rail, and a right sliding seat is installed on the right side of the sliding horizontal rail. The upper ends of the left and right sliding seats are respectively equipped with guide upright pins with guide bearings. The left sliding... The guide pin of the seat is installed in the linkage guide groove on the left side of the guide seat plate, and the guide pin of the right sliding seat is installed in the linkage guide groove on the right side of the guide seat plate. The left sliding seat is connected to the left seedling claw assembly through the left hinge arm and can make each seedling claw of the left seedling claw assembly move at intervals after taking seedlings to the top of the left seedling inlet of the matching seedling box. The right sliding seat is connected to the right seedling claw assembly through the right hinge arm and can make each seedling claw of the right seedling claw assembly move at intervals after taking seedlings to the top of the right seedling inlet of the matching seedling box.

[0004] However, both the seedling rack drive device with a seedling rack drive shaft and the flip drive device with a flip drive shaft have very complex structures, resulting in high manufacturing costs and frequent wear and replacement. By improving the structure, using cylinders to directly drive the sliding seedling claw frame to move back and forth along the longitudinal slide rail, and using cylinders to directly drive the flip seat frame to swing back and forth, the structure can be simplified and the manufacturing cost reduced. However, using a PLC or other control system to control the cylinder linkage to achieve coordinated operation between the various mechanisms will increase the cost of the transplanter's electrical components. In addition, the seedling feeding pawl mechanism of the transplanter's tray feeding and pushing device also requires cylinder drive. Therefore, designing a set of cylinder mechanical control mechanisms to achieve the linkage of the above three cylinders is a problem that needs to be solved. Utility Model Content

This ingenious structure reduces energy consumption. The rotating shaft drives the control component, which coordinates the actions of the first, second, and third mechanical switching valves, ensuring convenient and reliable adjustment and rational control.
