Embodiment Construction

[0048] refer to figure 1 , figure 2 , Figure 12 , a micro tillage machine proposed in this embodiment includes: a double crank rotary tillage and weeding mechanism, a speed regulating assembly and a walking assembly.

[0049] refer to Figure 10 , a double-crank rotary tillage and weeding mechanism proposed in this embodiment includes: a drive unit, a second shaft left gear 106, a second shaft right gear 107, a left forward gear 108, a right forward gear 109, a second transmission shaft 111, Left forward rotation sleeve 116, right forward rotation sleeve 117 and reverse cutter shaft 118. Both the second transmission shaft 111 and the reverse cutter shaft 118 are crankshafts, and are arranged parallel to each other.

[0050] The II-axis left gear 106 and the II-axis right gear 107 are coaxially arranged on the second transmission shaft 111 and located on opposite sides of the crankshaft section of the second transmission shaft 111, that is, the II-axis left gear 106 is ar...

Abstract

Disclosed is a double-crank rotary tillage weeding mechanism. The double-crank rotary tillage weeding mechanism comprises a driving unit, a shaft II left gear, a shaft II right gear, a left forward rotation gear, a right forward rotation gear, a second transmission shaft, a left forward rotation sleeve, a right forward rotation sleeve and a reverse rotation cutter shaft; the second transmission shaft and the reverse rotation cutter shaft are cranks and are arranged in parallel; the shaft II left gear and the shaft II right gear are coaxially arranged on the second transmission shaft and located on the two opposite sides of the crank section of the second transmission shaft; the second transmission shaft, the shaft II left gear and the shaft II right gear rotate synchronously; the crank section of the second transmission shaft is connected with the crank section of the reverse rotation cutter shaft through a connecting rod; and the second transmission shaft and the reverse rotation cutter shaft form a double-crank transmission mechanism. According to the double-crank rotary tillage weeding mechanism, soil can be crushed by rotary tillage, weeds can be effectively deeply buried, the weeding efficiency is effectively improved, and the soil in the center is pushed to be thrown to two sides while the soil is crushed, so that the hilling function is realized, and tea trees are prevented from lodging; and meanwhile, drainage ditches are formed in the middles of the rows to prevent waterlogging.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a double-crank rotary tillage and weeding mechanism and a tiller equipped with the mechanism. Background technique [0002] Tillers are semi-automated agricultural equipment and are widely used. The current micro-tiller cutter shaft rotates in one direction. During operation, weeds still float on the ground surface, making it difficult to effectively bury the weeds, and the weeding effect is poor. In addition, most of the micro tillage machines are powered by fuel oil at present, and the waste gas generated during the combustion of diesel and gasoline will pollute the crops, especially the tea garden, and affect the quality of tea; To change the speed, the existing gearbox has a large volume and weight, which affects its portability when used in a tiller, and cannot realize electronically controlled speed change. Contents of the invention [0003] In order to solve the d...
