A foot-operated betel nut taro extraction equipment and control method

Abstract

The invention relates to treadle type colocasia esculenta pulling equipment which is agricultural machinery used for harvesting colocasia esculentas by pulling. The treadle type colocasia esculenta pulling equipment comprises a pulling equipment body and a control device, wherein the control device is arranged on the pulling equipment body and used for controlling the pulling equipment body to operate, so that the automation of the machinery is improved; the pulling equipment body comprises a clamping mechanism, a soil loosening mechanism and a lifting mechanism; the clamping mechanism is used for clamping a colocasia esculenta petiole; the soil loosening mechanism is used for moving the clamping mechanism forward and backward; and the lifting mechanism is used for lifting or lowering the horizontal position of the clamping mechanism. The control device judges whether to enter the next step flow by acquiring a driving torque force of the clamping mechanism and the soil loosening mechanism. Meanwhile, a clamping force is mastered more properly, so that the colocasia esculenta petiole is prevented from being crushed or falling off during pulling due to an insufficient clamping force; and a more proper soil loosening condition is mastered, so that parent colocasia esculenta can be smoothly pulled out from the soil.

Description

technical field [0001] The invention relates to an agricultural machine for harvesting betel nut taro mother taro, in particular to a foot-operated betel nut taro extraction device and a control method. Background technique [0002] Now, betel nut taro is also called Lipu taro. It is mainly produced in coastal areas such as Guangxi and Fujian. Known as taro, it is the raw material of many taro snacks in Fujian, such as taro paste, taro buns, etc. However, the mother taro of betel nut taro all grows below the surface soil layer, with a length of 30 to 40 cm and a diameter of 12 to 15 cm. Today, betel nut taro growers still dig betel nut taro manually, which is not only laborious and laborious, but also lacks experience or Carelessness will cause the hoe to damage the mother taro. [0003] Application number CN201420532323.0 discloses a kind of taro excavation and patting soil picking harvester, which digs out taro from the ground by digging a shovel, but because the betel n...

Problems solved by technology

If you use machinery to extract, you need to consider that the betel nut petiole is a relatively brittle plant stem, and you need to control the clamping force; but because the betel nut taro is large in the soil, it cannot be extracted directly, and it needs to be extracted after loosening the soil.
