Mechanical shovel

Abstract

The invention discloses a mechanical shovel, mainly comprising a box (1), a driving wheel (2), a crank shaft (3), a connecting rod (4), a slide rod (5) and tines (9-10); the box is separated by a separation plate into two independent cavities, namely a crank shaft cavity and a tine cavity; the crank shaft and the connecting rod are arranged in the crank shaft cavity, the connecting rod is connected with a curved cam of the crank shaft, and one end of the crank shaft is connected with the driving wheel; the rear end of the slide rod is connected with the connecting rod in the crank shaft cavity, and the front end of the slide rod passes through the separation plate to be connected with the tines in the tine cavity. According to the mechanical shovel, by connecting mechanical power, the aims of effectively uprooting weeds and loosening soil, greatly improving agricultural field management efficiency and reducing labor intensity are achieved; the mechanical shovel has the characteristics of being light in weight, laborsaving and convenient in operation, free of farmland ground condition limitation, thorough in weeding, and ideal in soil loosening moisture conservation effect, and is widely applied to weed uprooting and soil loosening moisture conservation in orchards, tea gardens, gardens, nurseries, flat ground, hilly land and mountain land.

Description

technical field [0001] The invention belongs to the technical field of farming tools, and mainly relates to a mechanical hoe. Widely used in orchards, tea gardens, gardens, nurseries, as well as shoveling and loosening weeds in flat, hilly and mountainous areas. Background technique [0002] During the growth of crops, soil loosening and moisture conservation is an important part of field management. By loosening the soil, it achieves the purpose of weeding, water storage, preventing soil moisture from evaporating, and promoting the robust growth of crops. [0003] Weeds are the enemy of agricultural field management. If they are not eradicated in time, they will compete with crops for nutrients, water, sunlight and space, hinder the ventilation and light transmission of the field, seriously affect the growth of crops, and reduce the yield and quality of crops. Therefore, in the whole process of crop growth, it is necessary to carry out multiple intertillage and weeding. ...

AI Technical Summary

Problems solved by technology

[0004] Take the commonly used rotary tillage weeder as an example, when rotary tillage weeding, it can only eradicate the grass on the soil surface, and only small weeds can be removed Eradication cannot eradicate the roots of the soil, but weeds are very strong in life. If we do not "cut the weeds and eradicate the roots", they will quickly re-grow on the original roots, which will increase the workload of weeding.

Moreover, this type of weeder has great limitations when used in hilly land, hard ground and places with many stones, such as low flexibility, high jumping / vibration, laborious operation, and dust raised during the rotary tillage process will damage the Workers' health, weeds are easy to entangle the cutter, affect the weeding effect, and hardly have the effect of loosening the soil
