Description

TECHNICAL FIELD

[0001] The present application belongs to the field of rice transplanting, in particular to an automatic seedling supplementing device of a rice transplanter. BACKGROUND

[0002] The rice planting area in China ranks second in the world, and the total output value ranks first. Rice production plays a crucial role in China's food security. Promoting rice transplanting mechanization is an effective way to improve rice planting efficiency. Rice transplanting mechanization is the main technology of rice mechanized production in China.

[0003] A rice transplanter is a planting machine that plants rice seedlings in a paddy field. Its function is to improve the efficiency and quality of transplanting, achieve reasonable planting density, and facilitate the mechanization of subsequent operations. Due to the harsh working environment of the paddy field, the transplanter is prone to jolting when working in the paddy field, causing the driving path of the transplanter to deviate, thereby affecting the operation quality and efficiency of the transplanter. An unmanned transplanter can reduce dependence on labor, effectively improve operation quality and efficiency, and not overly rely on the operation level of the operator, meeting people's new requirements for agricultural production and being resistant to global competition.

[0004] Currently, the seedling supplementing method of unmanned transplanter is manually supplemented by workers, which not only wastes manpower, increases production cost, and reduces production efficiency, but also slows down the mechanization process of rice production, making it impossible to achieve fully unmanned operation of rice transplanting. SUMMARY

[0005] Therefore, the present application aims to provide an automatic seedling supplementing device of a rice transplanter to solve the problem of low efficiency caused by the need for manual seedling supplementing in unmanned transplanter.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: an automatic seedling supplementing device of a rice transplanter, comprising a seedling rack conveying belt assembly, a main conveying assembly, a planting platform, a transplanter assembly, and a lifting seedling rack assembly.

The first sensor is electrically connected to the conveyor belt controller, and the second sensor is used to receive signals from the first signal transmitter and the second signal transmitter.

[0011] Furthermore, the distance between each two of the seedling rack conveyor belts is greater than the width of the seedling tray supporting plate, and the seedling tray supporting plates at corresponding positions can pass through the gaps between the seedling rack conveyor belts at corresponding positions when moving up and down.

[0012] Furthermore, the main conveying assembly includes a sensing and automatic control system, a seedling delivery base, an optical sensor, a main conveyor belt system and a pushing component. The seedling delivery base is arranged on the rice transplanter assembly, the sensing and automatic control system is arranged below the seedling delivery base, and the pushing component is connected to the seedling delivery base for pushing the seedling tray toward the planting platform. There are multiple optical sensors, and the multiple optical sensors are arranged at equal intervals on the seedling delivery base and their positions correspond one-to-one to the seedling tray conveying grooves of the planting platform. The sensing and automatic control system collects signals from the second sensors on both sides and controls the main conveyor belt system to transport the seedling tray forward or reverse accordingly. After collecting signals from all the optical sensors, the sensing and automatic control system controls the action of the pushing component.

[0018] 2. The main conveying belt system can be controlled to forwardly convey or reversely convey by the cooperation of the sensor, so that the seedling trays on the seedling frames on both sides are all conveyed out.

[0019] 3. The seedling trays arranged in order can be pushed downward as a whole, so that the seedling trays in the planting platform are replenished. DETAILED DESCRIPTION
