Technical Field
The invention relates to the technical field of agricultural machinery cultivation equipment, in particular to a weeding and ridging plough head structure and a multifunctional device for tobacco cultivation.
Background
In the tobacco cultivation process, weeding and ridging are key and necessary links of field management, and weeding is to remove weeds, reduce water and fertilizer consumption in soil and prevent breeding of diseases and pests and spread of diseases. The timely weed removal is an important field management measure for the normal growth and development of tobacco leaves, generally manual weeding is carried out, and a small part of places with good production level are provided with a weeding machine and a hiller. The hilling is to pile up the inter-row soil at the root of the plant, so as to increase the root number of the tobacco plant and improve the stress resistance of the tobacco plant. The hilling can improve the yield and the quality of the tobacco leaves, can also improve the ground temperature to protect plants needing to live through the winter, thicken a loose layer of the soil, play a role in isolating the external cold air, prevent the soil temperature from being sharply reduced due to the influence of the external cold air, relatively improve the soil temperature and play a role in protecting the plants from live through the winter. The ridging method is determined according to the seeding method, and the ridging is performed into trapezoidal or triangular ridges; a hilling ploughshare and corresponding equipment are generally used.
However, in the current production, the weeding machine and the hiller used in the current weeding and hilling are separated devices, tobacco growers need to use the weeding device and replace the weeding device with the hiller to move to one side, so that time and labor are wasted, the efficiency is not high, and the current hilling structure is not suitable for the hilling increase of the ridge height and the shape requirement of tobacco.
