Problems solved by technology

The transmission mechanism of this kind of belt often causes the seedling delivery belt to deviate during operation, which makes the seedling delivery belt wear seriously and the work reliability is poor
For this reason, people often use relatively large tension force to tighten the seedling delivery belt, which causes the working friction resistance of the shaft that drives the seedling delivery belt to rotate to be too large, and the parts of the bearing and the seedling delivery belt are easily damaged.
In addition, the current seedling delivery belt transmission mechanism adopts 2 separated smooth pulleys and 2 separated tooth surface pulleys, which makes installation inconvenient, time-consuming and labor-intensive

Abstract

The invention discloses a middle synchronous belt driven seedling delivery mechanism, which is composed of a machine frame, a driven shaft, a hexagonal shaft, a driven belt pulley, a driving belt pulley, and a seedling delivery belt. The driven belt pulley is in a dumbbell-like shape with the middle part being smaller in diameter and two ends being larger in diameter. The driving belt pulley is a cylinder body with the middle part having teeth and two ends being smooth. The teeth on a left tooth-surface belt pulley and the teeth on a right tooth-surface belt pulley are staggered. The transmission teeth of the seedling delivery belt are arranged on the middle part of the belt. The seedling delivery mechanism is free of deviation during operation and is convenient to install.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an intermediate synchronous belt-driven seedling delivery mechanism. Background technique [0002] The seedling box of the rice transplanter is an important part for transporting seedlings, and the number of seedling delivery belts is set according to the number of transplanting rows. In the current seedling delivery belt transmission mechanism, both sides of the seedling delivery belt are synchronous belt teeth, and the middle is a smooth surface. 2 smooth driven pulleys and 2 tooth surface driving pulleys are arranged on both sides of the belt. Cooperate with the timing belt teeth on the belt surface. The transmission mechanism of this belt often causes the seedling sending belt to deviate in the operation, so that the sending seedling belt wears seriously, and the reliability of work is relatively poor. For this reason, people often adopt relatively large tension force to tighten th...
