Watering device for a transplanting machine

Abstract

A watering device for a transplanter relates to the field of agricultural machinery. Transplanting is a crucial step in the planting of many agricultural crops, and adequate watering during transplanting is key to ensuring seedling survival. Therefore, it is essential to install a watering device on the transplanter. This invention comprises a valve, an inlet pipe, a pipe clamp, a water reservoir, a water distribution grid, a water distribution hole, a guide, a guide grid, a distributor, a watering device, a drainage pipe, a crank hinge seat, a crank hinge shaft, a crank, a connecting rod, a water reservoir hinge seat, a water reservoir hinge shaft, and an outlet hole, and is installed on the transplanter. One end of the inlet pipe is connected to the water tank of the transplanter via a valve, and the other end is connected to the water reservoir. During operation, the rotating crank drives the connecting rod to move, and the connecting rod drives the water reservoir to tilt around the water reservoir hinge shaft, thereby injecting a certain amount of water into the guide at once, and then watering the seedlings through the distributor, drainage pipe, and watering device. Its advantages include high water resource utilization, synchronization with transplanting operations, and avoidance of water flow impacting seedlings and soil.

Description

Technical Field

[0001] This invention relates to a watering device for transplanters, and particularly to transplanting machinery for regions, seasons, and varieties requiring drought resistance and seedling protection during transplanting, belonging to the field of agricultural machinery technology. Background Technology

[0002] my country is a major agricultural country with a large planting area and a wide variety of agricultural and cash crops, a large portion of which require seedling transplanting. In arid regions and during certain seasons, seedlings of agricultural and cash crops (such as tobacco) need immediate watering after transplanting to combat drought, protect seedlings, improve survival rates, and shorten the recovery period. Therefore, it is essential to equip transplanting machines with watering devices that operate synchronously with the transplanting process.

[0003] Currently, some transplanter irrigation devices use solenoid valves to control the flow of water through a pipe connected to a water tank, enabling intermittent watering of the transplanted seedlings. This inevitably increases the investment in the solenoid valve assembly and its corresponding control system. Furthermore, the diameter of the water pipe and solenoid valve can lead to ineffective irrigation and waste of water between seedlings. Other transplanter irrigation devices directly introduce the acquired irrigation water into a specially designed container, using a simple valve on the container for intermittent watering. However, due to the vibration and shaking of the transplanter during operation, these simple valves are difficult to seal completely, again resulting in unnecessary watering between seedlings and low water resource utilization.

[0004] This invention continuously introduces a certain amount of irrigation water into the water storage tank through the inlet pipe during the time interval between two transplantings, then injects it all at once into the diverter located below. The water is then accurately applied to each transplanted seedling through the distributor, drainage pipe, and watering device. This synchronized watering operation with the transplanting process avoids water leakage into areas between seedlings. Furthermore, by changing the number of water distribution grids in the water storage tank and the diverter grids, as well as the corresponding number of diverter inlets and outlets, drainage pipes, and watering devices, it can accommodate simultaneous watering operations for transplanting rows with varying numbers of rows. This achieves the goal of highly efficient water resource utilization and therefore has significant practical implications. Summary of the Invention
