Rice transplanter type vehicle transmission

Abstract

The invention relates to a rice transplanter type vehicle transmission, comprising a transmission cabinet, a differential, steering clutches, a brake, and a steering transmission mechanism. The differential is installed on the transmission cabinet and is connected with a left half axle and a right half axle. The transfer-drive sliding variable gear of a transmission shaft is corresponding to a transfer-drive duplicate gear which is installed on a transfer-drive transmission shaft. A transfer-drive driving taper gear on the transfer-drive transmission shaft is meshed with a transfer-drive output taper gear shaft. Half-shaft output driving taper gears are respectively connected with a left tail end output shaft and a right tail end output shaft through a half-shaft output driven taper gear and respective steering clutches. A differential lock installed on the left half axle is opposite to a differential housing. The brake is installed on a right housing and a differential transmission shaft. The second transfer-drive taper gear on the differential housing is meshed with a second transfer-drive taper gear shaft. The rice transplanter type vehicle transmission is characterized by compact structure, good installation and maintainability, and reliable use, and adapting to multifunctional configuration requirements.

Description

technical field [0001] The invention relates to a vehicle transmission of a rice transplanter type, and belongs to the technical field of rice transplanter power output. Background technique [0002] The rice transplanter transmits the power to the transplanting mechanism and the seedling delivery mechanism respectively. With the mutual cooperation of the two mechanisms, the needle of the transplanting mechanism is inserted into the seedling block to grab the seedlings, and it is taken out and moved down. When it moves to the set seedling depth At this time, the seedlings are pressed down from the needles by the transplanting fork in the transplanting mechanism to complete a process of transplanting. At the same time, through the floating plate and the hydraulic system, the relative positions of the traveling wheels and the machine body and the relative positions of the floating plate and the seedling needles are controlled, so that the depth of rice transplanting is basical...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the transmission systems of high-speed rice transplanters use two boxes to form a split box structure. It is difficult to change the functional configuration of the inverted power output shaft, and the production technology is difficult. In addition, when the power output shaft fails, it is difficult to disassemble and assemble. The system structure is not compact

Secondly, the existing transmission is equipped with a partial power output to drive the rice transplanting device to work, but the partial power output is decelerated in two stages, and can only output a single-speed, one-way rotating working speed. The rice transplanting unit needs to add soil preparation tools and fertilization equipment and other functional requirements, the ability to adapt to compound operation equipment or variant products is insufficient

Furthermore, the current existing travel brake speed change mechanism is to install the brake on the central transmission shaft of the gearbox, but due to the influence of the structural requirements of the brake itself, the center distance between the central transmission shaft and the transmission shaft is relatively large, and It also makes the center distance between the central transmission shaft and the half shaft larger, resulting in a larger transmission case, so the size of the transmission gear is also larger, and the overall technical economy of the transmission is poor

In addition, the steering transmission mechanism and the transmission of the existing rice-transplanting vehicle are split structures, and the steering transmission mechanism is installed outside the transmission case. Processing, so the production cost is high, and the operation is inconvenient during installation and maintenance
