Gap-adjustable potato seed conveying device

Abstract

The invention provides a gap-adjustable potato seed conveying device. The gap-adjustable potato seed conveying device is characterized in that two ends of a driven shaft fixedly provided with a driven roll are supported on brackets I; two ends of a driving shaft fixedly provided with a driving roll are located in runners and are supported on brackets II through tensioning devices; a conveying belt is hung on the driving roll and the driven roll, two rows of potato seed bowls are fixed on the outer surface of the conveying belt, a fixed plate is arranged on one sides of the potato seed bowls, and seed throwing tongues are arranged at bowl edge parts, opposite to the fixed plate, of the potato seed bowls; the upper ends of two side faces of a U-shaped protecting cover are respectively fixed on the brackets II on two sides, and the lower ends of the two side faces of the U-shaped protecting cover are respectively fixed on the brackets I on the two sides; the outer surfaces of two side faces of an m-shaped potato guiding cylinder are located between the inner surfaces of two side faces of the protecting cover; two sets of gap adjustment devices are arranged between the bottom surface of the protecting cover and the m-shaped top end of the potato guiding cylinder; relative positions of the potato guiding cylinder and the potato seed bowls can be changed by loosening nuts on the outer side of the bottom of the protecting cover and rotating screw rods I or the screw rods II. The gap-adjustable potato seed conveying device has the beneficial effects that gaps are conveniently adjusted, potato seeds are smoothly thrown out, and the quantity of the potato seeds is accurately controlled.

Description

technical field [0001] The invention provides a gap-adjustable potato seed conveying device, which is mainly used in a potato planter. Background technique [0002] At present, most of the existing potato planting machines fix a simple seed potato bowl on the conveyor chain or conveyor belt. Due to its simple structure, the amplitude of the conveyor chain or conveyor belt cannot be adjusted, and the control of the number of potato seeds in the potato seed bowl is not enough. Precise, it is very easy to cause missed or repeated seeds, which will affect the later growth and development of potatoes. Therefore, we have invented a "planting device for bowl-spoon seeding of root crops", authorized patent number: ZL2012200930666. However, it has been found through testing and practical application that the gap between the potato seed conveying device involved in this patented technology cannot be adjusted between the potato seed bowl and the guide tube. The cylinders collide with...

AI Technical Summary

Problems solved by technology

However, it has been found through testing and practical application that the gap between the seed potato bowl and the potato guide tube of the potato seed conveying device involved in this patented technology cannot be adjusted. The cylinders collide with each other and rub against each other. If they are too large, the potato seeds will fall from the gap between the potato seed bowl and the guide tube when the potato seed bowl moves down, causing the front one to replant and the rear one to replant. one plant misses

In addition, since the gap cannot be adjusted, it cannot adapt to the sowing of various potato varieties with different seed block sizes.
