Description

Technical Field

[0001] The utility model relates to the technical field of flue-cured tobacco planting auxiliary devices, and particularly relates to a weeding and ridge-forming machine for large field plots. Background Technique

[0002] After the transplanting of flue-cured tobacco is completed, according to its growth cycle characteristics, it can be divided into four periods: seedling recovery, root extension, vigorous growth, and maturity; the work in the root extension period needs to focus on cultivating the roots of tobacco plants, increasing the root mass, and appropriately controlling the growth rate of stems and leaves. The main tasks include uncovering the film, intertilling, weeding, ditching, and ridge-forming and soil banking; in some areas where large agricultural machinery is not suitable for working, when weeding and ditching, most of the time, a walking tractor rotary tiller is directly used to loosen the soil and remove weeds in the ridge ditch area. Then, farmers manually transfer the soil in the ditch to the periphery of the ridge body through tools such as hoes for soil banking to increase the active soil layer and height of the ridge surface, which is beneficial to the growth of adventitious roots. Such an operation form is obviously more troublesome and cannot meet the requirement of integrated operation for weeding and ridge-forming and soil banking; and this is also the main problem faced at present.

[0023] The extension support plate 2 is a folding plate member, one end of which is detachably installed on the tailstock 1 through a bolt assembly, and the other end is arranged close to the ground.

[0024] The function support 6 includes a U-shaped plate; positioning blocks are installed on the two extending ends of the U-shaped plate; one end of the positioning block is installed on the extension plate 2, and guiding grooves are formed on both positioning blocks.

[0025] Two cams 5 are provided in total; the two cams 5 are coaxial and are respectively installed at different height positions on the output shaft of the reducer 4; two push rods 7 are also provided, and the two push rods 7 are respectively installed on both sides of the function support 6 corresponding to the two cams; the length of the sliding groove is greater than the stroke of the cam.

[0026] A step is further arranged in the middle of the output shaft of the reducer 4; the two cams are respectively installed on the upper and lower sides of the step; a connecting plate 10 is also arranged between the two push rods 7; a sliding groove is formed in the middle of the connecting plate 10; the width of the sliding groove is consistent with the outer diameter of the step; the connecting plate 10 can reciprocally slide relative to the step at the sliding groove along with the movement of the push rod 7; the length of the sliding groove is greater than the stroke of the cam 5.

[0027] The push rod 7 includes a support top plate that contacts the cam 5; an output rod is installed on one end face of the support top plate; one end of the output rod passes through the guide groove and is connected to the link assembly 8; the installation heights of the support top plates on the two push rods 7 are respectively consistent with the heights of the cams 5 at the corresponding positions, and the push rods 7 at different heights do not interfere with the cams 5.

[0029] The working principle of the utility model device in this embodiment is as follows: Since the extension support plate is arranged at the tail of the rotary tiller, when the rotary tiller loosens the soil forward, by turning on the motor on the extension support plate, the reduction box can output torque to the two cams. The rotation of the cams will drive the push rods at the corresponding end sides to reciprocate at the notches on the functional brackets. When the push rods act, they will drive the link assembly to form a swing rod member, thereby causing the earthmoving plates at the two side ends of the extension support plate to swing, so that the soil sent by the rotary tiller can be pushed to both sides of the ridge body by the earthmoving plates, thus completing the ridging.
