Single-way clutch type seeding and reseeding integrated potato planter

Abstract

The invention relates to a single-way clutch type seeding and reseeding integrated potato planter which comprises a frame and a transmission system. A seed box is arranged above the frame, a chain spoon type seed-metering device is vertically arranged on the seed box, a double-crank four-connecting rod mechanism is arranged below the chain spoon type seed-metering device, the double-crank four-connecting rod mechanism is also located on the frame below the seed box and is linked with a ground wheel device, a soil-taking and extracting device is arranged on the frame behind the double-crank four-connecting rod mechanism, the soil-taking and extracting device is linked with a transmission box, a detection device is arranged outside a seed protecting groove, the detection device is connected to a control system device, a motor is controlled by the control system device, a clutch system is arranged at the lower end of the chain spoon type seed-metering device, the clutch system sleeves on a lower shaft of the chain spoon type seed-metering device at the lower end of the chain spoon type seed-metering device, and the clutch system is separately linked with the motor and the double-crank four-connecting rod mechanism. The planter provided by the invention can perform normal seeding and miss-seeding detection, and also can achieve a purpose of miss-seeding compensation on the premise of not additionally arranging a reseeding box.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a one-way clutch type integrated potato planter for sowing and reseeding. Background technique [0002] Potato is the fourth largest staple food crop in my country. In 2015, the planting area of ​​potato in my country reached 5.6146 million hm 2 , and maintained at 5.3333 million hm for a long time 2 above, ranking first in the world. In 2015, after my country officially established the potato as a staple food crop, the planting target for 2020 is that the planting area exceeds 6,666,700 hm 2 , the output reached 150 million tons. However, the mechanization level of potato planting in my country is still relatively low. The domestically developed suspended potato planters have low operating efficiency. At present, the chain scoop type seed metering device is mostly used, which has the advantages of high reliability, low cost, adjustable plant spacing, and adaptability ...

AI Technical Summary

Problems solved by technology

However, due to the different sizes and shapes of seed potato pieces, the rate of missed seeding in the operation of potato planters is increased. It is difficult to detect missed seeding and realize replanting, which has always been a problem that plagues the mechanized potato planting of chain spoon seed metering machines.

On the one hand, there is no forming planter that integrates seeding and reseeding in the market. On the other hand, the existing missed-seeding compensation laboratory products all need to be equipped with a separate re-seeding box and a relatively complicated cavity mechanism to realize the waiting time. The filling and replanting of potato seeds complicate the system and reduce the reliability of engineering realization, especially the complex cavity is very likely to cause secondary blockage, and the placement rate of potato seeds to be filled is not ideal
