Device for electrically adjusting high-low speed of speed change wheel

Abstract

The invention relates to a device for electrically adjusting the high-low speed of a speed change wheel. The device comprises an electric adjusting frame mechanism, a belt wheel mechanism and a vertical bracket mechanism. The electric adjusting frame mechanism comprises a connecting seat plate, a motor, a speed adjusting gear set, an adjusting rod and a vertical bracket movable sleeve. The motor is fixedly mounted on the connecting seat plate, an output shaft of the motor and the adjusting rod are mounted in transmission through the speed adjusting gear set, a threaded rod is arranged on the front portion of the adjusting rod, and the threaded rod and the vertical bracket movable sleeve are mounted in engagement. The vertical bracket mechanism comprises a fixing support and a vertical bracket, the upper end of the vertical bracket is hinged to the fixing support, and the lower end of the vertical bracket is hinged to the vertical bracket movable sleeve. The belt wheel mechanism comprises a belt wheel shaft, a bearing block, a speed change belt wheel and a clutch, the bearing block and the connecting seat plate are fixedly mounted, and the clutch and the middle of the vertical bracket are fixedly mounted. The high-low speed of the speed change wheel can be electrically adjusted, control is easy and convenient, the requirements of the speed needed for users to harvest different crops can be effectively met, and the harvesting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a device for electrically adjusting the high and low speeds of a speed change wheel. Background technique [0002] Due to the strong seasonality of crop harvesting, it is necessary to improve harvesting efficiency and provide more time for harvesting. Moreover, different harvesting speeds are required when different crops are harvested. Therefore, in agricultural machinery transmission devices such as harvesters, it is usually necessary to adjust the speed through the speed change wheel to achieve different and fastest harvesting speeds and meet the requirements of harvesting speed and harvesting efficiency. The existing speed change wheels are generally manually adjusted or hydraulically adjusted, which has the disadvantages of low efficiency, high cost, and large space occupation. At present, there is no device that can realize the simple and convenient adjustment of the...
