High-speed planting transmission device and method

Abstract

The invention discloses a high-speed plant inserting transmission device and method, and belongs to the field of agricultural machines. In the device, a transmission box is composed of a left box anda right box. A transmission bevel gear shaft, an inverted-T-shaped half clutch, a U-shaped half clutch, a transmission safety spring and a transmission pressing disc sequentially sleeve the upper portion of a combined shaft, and a transmission safety component is formed. The upper portion of an intermediate shaft and a lower hole of the combined shaft are in clearance fit. A driven half clutch disc, a plant inserting safety and a plant inserting pressing disc sequentially sleeve the intermediate shaft, and a plant inserting safety clutch component is formed. The transmission safety component and the plant inserting safety clutch component synchronously rotate or rotate in a sliding manner through thrust changes of the toothed combined face of a driving piece and a driven piece, and accordingly a power transmission system and transplanting mechanisms are protected. The space structure size is effectively reduced through the device, and the transplanting mechanism distance meets the requirement of the rice planting agricultural technology for the line spacing; and separation or reunion is achieved by stretching a clutch pin in or moving the clutch pin out of the driven half clutch disc spiral face, and grouping independent control of the transplanting mechanisms is achieved. The whole device is compact in structure, transmission is stable, the transmission and transplanting safety protection function is achieved, and reliability and safety are high.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a narrow row-spacing transmission device and method for special safety transmission and planting protection of a separate planting mechanism during rice mechanized high-speed planting. Background technique [0002] The clutch parts, safety protection parts, transmission parts and their structure of the power transmission box of the splitting mechanism of the high-speed rice transplanter are the key to ensure the normal operation of the rice transplanter, which directly affects the reliability and safety of the transplanter operation, and its structure directly affects the splitting. The distance between the institutions affects whether the planting row spacing matches the agronomic requirements after transplanting. At present, the transmission safety parts and planting safety parts of the power transmission device of the high-speed rice transplanter are basically...

Problems solved by technology

[0003] The purpose of the present invention is to overcome that the centralized arrangement of transmission safety devices of the existing rice transplanter sub-insertion mechanism cannot effectively protect the safe transmission of a single transmission device, and the planting safety clutch parts are placed horizontally or in the sub-insertion mechanism to increase the transverse structure, chain transmission and Due to the disadvantages of incompatibility with high-speed planting and the inability to independently control the inserting mechanism, the present invention provides a special-purpose inserting mechanism that is equipped with transmission safety clutch parts and planting safety clutch parts at both ends of the transmission shaft and realizes power transmission through the drive shaft. The power transmission device greatly reduces the structural size of the transmission system, so that the distance between adjacent insertion and insertion mechanisms can adapt to the row spacing required by rice planting agronomy, with high transmission efficiency and good performance. The sub-insertion mechanism and the entire power transmission system provide safety protection, and are ideal devices for the power transmission of the sub-insertion mechanism of rice high-speed rice transplanters
