Problems solved by technology

[0003] However, the actual ridge surface is not smooth, figure 1 It is prior art (referring to patent literature CN2817331Y), in the work of existing mechanical type weeding and scarifying machine, the height above the ground of control weeder assembly is realized by depth-limiting supporting plate 7, but when the ridge surface is uneven and causes the depth-limiting supporting plate When the board jumps, the weeding roller also jumps, and the jumping range of the weeding roller is smaller than the jumping range of the depth-limiting support plate
It makes it impossible to adjust the depth with the height of the ridge surface with the weeding roller
Furthermore, due to the large contact area between the depth-limiting supporting plate and the ridge surface, its bonding ability to the ridge surface is not strong
[0004] In addition, when the existing chain 5 works, the direction of rotation of the driving sprocket is as follows: figure 1 As shown, when the transmission load increases, the chain drives the passive sprocket to generate a force that lifts the weeding roller upwards, reducing the depth of the weeding roller into the ridge surface, so that the weeding roller cannot meet the work requirements

Embodiment Construction

[0014] The forward and backward directions of the present invention are relative to the forward and backward directions when the subsoiler weeder works. The left and right directions are the left and right sides of the forward direction, and the inner and outer directions are the direction of the ridge surface relative to the furrow, wherein the ridge surface is inside the two furrows.

[0015] Such as Figure 2-3 A single subsoiling weeder is shown, including a frame 1, a depth-gauge wheel assembly 2, a weeding roller assembly 3 and a weeding roller assembly frame 4;

[0016] Among them, the frame is connected to the agricultural vehicle, and the agricultural vehicle pulls the subsoil weeder unit along the F direction in 2;

[0017] The weeding roller assembly frame 4 comprises the left and right weeding parallelogram connecting rods 41 positioned at the left and right sides of the frame. The two ends of the weeding front rod and the weeding rear rod are pivotally connected...

Abstract

The invention provides a deep scarification weeding machine. According to the deep scarification weeding machine, a parallelogram connecting rod is utilized to achieve the movement of a weeding rollerin the direction perpendicular to a rack, and the ground clearance of the weeding machine is controlled through a depth roller, so that when the weeding roller throbs due to the uneven ridge surface,the depth roller throbs along with the weeding roller together, and the throbbing range of the depth roller is the same as that of the weeding roller, thereby ensuring the invariability of the working depth of the weeding roller, and avoiding the situation that the weeding roller is lifted unnecessarily due to the corresponding increase of a weeding roller power transmission chain wheel. The deepscarification weeding machine has the advantages that through the combination of a weeding roller power assembly and the weeding parallelogram connecting rod, it is achieved that the deformation of the weeding parallelogram connecting rod does not affect the normal work of a first chain, and it is also achieved that the first chain is inhibited from separating the weeding roller from the ridge surface when the transmission load is increased, thereby meeting the depth requirements of the weeding roller in the ridge surface.

Description

technical field [0001] The invention relates to the field of loosening and weeding in agricultural intertillage, in particular to a single subsoiling weeding machine and a subsoiling weeding machine using the same. Background technique [0002] The use of mechanical weeding and scarifying machines before and after the emergence of crops has begun to be recognized. Patent CN104737861A discloses a mechanical weeding and scarifying machine, which uses a mechanical weeding and scarifying machine for different crops in different days after sowing. Deep soil weeding and loosening operations; for different leaf stages or plant heights after emergence of different crops, use a mechanical weeding and loosening machine to perform the first and second weeding and loosening operations at different depths of crops after emergence. This method is simple , scientific and reasonable, the effect of weeding and loosening the soil is good, the rate of injury to seedlings is low, and the residu...
