Problems solved by technology

[0004] Moreover, because agricultural knives or weeding knives must be buried in the soil, the bottom of the knives should be at the bottom of the entire agricultural machine. When the machine is put down to prepare for work, the knives must first touch the ground. Shafts, sensor shafts, etc. will bear the weight of the entire machine, which makes the tool and tool connection easy to damage and reduces the service life

Embodiment 1

[0023] Such as figure 1 As shown, the hoeing knife depth of the present embodiment and the continuous adjustment mechanism of the burrowing angle are particularly aimed at the adjustment of the weeding knife of various weeding machines or the weeding knife of the weeding knife unit with its own power element or detection device, including the adjustment of the weeding knife with the carrier 6 The fixedly connected frame 5 is used to fix the connecting plate 1 connecting the cutting tool, the angle adjustment mechanism for entering the soil and the adjustment mechanism for the depth of entry into the soil.

[0024] Wherein, the carrier 6 can be any agricultural machinery that needs to adjust the cutting depth or cutting angle, or a parallelogram profiling mechanism. The connecting plate 1 can be fixedly connected with the agricultural knife or the weeding knife unit by bolts.

[0025] The entry angle adjustment mechanism includes a connecting rod 3 in a U-shaped structure, th...

Embodiment 2

[0042] Such as image 3 As shown, the continuous adjustment mechanism of the depth of the hoe knife into the soil and the angle of the hoe knife in this embodiment includes a frame 5 fixedly connected to the carrier 6, a connecting plate 1 for fixedly connecting the knife, a mechanism for adjusting the angle of entry into the soil, and an adjustment mechanism for the depth of entry into the soil.

[0043] Wherein the frame 5, the connecting plate 1 and the adjusting mechanism of the entry angle are the same as in the first embodiment, and its structure and working process refer to the contents of the first embodiment.

[0044] In this embodiment, the mechanism for adjusting the entry depth includes a second depth adjustment connecting frame rod 11 rotatably connected to the frame 5 through a hinge, and the second depth adjusting connecting frame rod 11 is arranged with two sections of thread in opposite directions of rotation. , and a nut sleeve with an internal thread that ma...

Abstract

The invention relates to the technical field of modern agricultural equipment, and in particular relates to a hoe entering depth and entering angle continuous adjusting mechanism. The hoe entering depth and entering angle continuous adjusting mechanism comprises a stander (5) which is fixedly connected with a carrier (6), a connecting plate (1) which is fixedly connected with a cutter, an entering angle adjusting mechanism and an entering depth adjusting mechanism. The hoe entering depth and entering angle continuous adjusting mechanism is simple in structure, effective, convenient to machine and install and strong in practicability. The entering angle of the cutter is adjusted by adopting a four-bar mechanism with an adjustable side link; the entering depth of the cutter is adjusted by adopting a five-bar mechanism with two degrees of adjustable freedom of a side link and no dead point (as shown in figure 4), or the entering depth of the cutter is adjusted by adopting a four-bar mechanism with one degree of adjustable freedom of a side link and no dead point through the deformation (as shown in figure 5); and moreover, the cutter is enabled to have a function to float upwards after being stressed, so that a buffering effect can be realized, the cutter and a cutter connecting piece can be protected, and the service lives of the cutter and the cutter connecting piece can be prolonged.

Description

technical field [0001] The invention relates to the technical field of modern agricultural equipment, in particular to a mechanism for continuously adjusting the depth and angle of the hoe knife into the soil. weeding knife). Background technique [0002] In the early 1960s, my country put forward a slogan for agricultural development according to the national conditions at that time: the fundamental way out of agriculture lies in mechanization. After many years, many areas in my country have basically realized mechanized operations in the main production links of some crops. Facing the new situation and new characteristics of agricultural production at home and abroad, the development of agricultural machinery must also adapt to it. Drawing on the experience of foreign agricultural machinery development, my country's agricultural machinery should also gradually change to the direction of automation, intelligence and refinement. [0003] Mechanical farming or mechanical we...
