Seed potato conveying device with adjustable amplitude

Abstract

The invention provides a seed potato conveying device with adjustable amplitude. The seed potato conveying device is characterized in that the two ends of a driven shaft fixedly provided with a driven roll are supported on a support, the two ends of a driving shaft fixedly provided with a driving roll are located in a slideway and supported on the support through a tensioning device, the same conveyor belt is hung on the driving roll and the driven roll, two rows of potato sowing bowls are fixed on the outer surface of the conveyor belt, two rows of protruding blocks are arranged on the inner surface of the conveyor belt, the two ends of a whirling stand fixedly provided with two supporting legs are supported on the support, rolling shafts with the two ends provided with rolling bodies are fixed to the ends of the supporting legs, corner wheels are fixed to the ends of the supporting legs of the swirling stand, a U-shaped connector is hinged to a lug of the support, a fine adjusting screw rod is screwed into a threaded hole of the connector after penetrating through the upper bent part of an adjusting frame and a round hole of the lug, a hand wheel is fixed to the other end, one end of a rough adjusting handle is fixed to the extending end, penetrating through the support, of the whirling stand, and the other end of the rough adjusting handle is installed in a long groove of the adjusting frame through the hand wheel. According to the seed potato conveying device, the amplitude is adjustable, and the quantity of seed potatoes can be controlled accurately.

Description

technical field [0001] The invention provides an amplitude-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 tests and practical applications that the vibration effect of the potato seed conveying device involved in this patented technology is not ideal enough, and the amplitude cannot be adjusted. The bowl-and-spoon ty...

Problems solved by technology

However, it has been found through experiments and practical applications that the vibration effect of the potato seed conveying device involved in this patented technology is not ideal, and the amplitude cannot be adjusted.

The bowl-and-spoon type potato seed bowl is used to dig more potato seeds at one time, which increases the vibration burden and is not easy to adjust, thus resulting in a large number of re-planting phenomena; in addition, due to digging more potato seeds, the potato seeds shaken off after vibration Potato seeds after shaking are not easy to slide down, affecting the sowing effect, and prone to repeated seeding and missed seeding
