Problems solved by technology

[0002] The stability of tillage depth is the main performance index of the operation quality of tillage agricultural machinery (rotary tiller, plow, etc.). Due to the unevenness of the farmland, the working depth of the machinery changes with the pitch and inclination of the tractor, and the working depth of the machinery can be determined by The tractor adjusts the settings, but it is easy to plow deep in the low-lying areas of the farmland and shallow in the high areas, resulting in poor plowing effects and low operating efficiency, and damage to the hard bottom of the farmland, and will also affect the flatness of the machine after plowing, etc.
Although these problems can be reduced or alleviated by manually adjusting the three-point suspension mechanism of the tractor, there is a delay in the adjustment and due to personal experience, in most cases, overshoot or insufficient adjustment will occur, resulting in missed tillage, too deep plowing, or even the tractor is overloaded and stalled , not only affects the quality of work, but also affects the service life of tractors and implements

Embodiment 1

[0034]A mechanism for continuously adjusting the elevation of a machine tool mainly includes an elevation adjustment bracket, a lower lifting bracket, an upper pull rod, and two elevation oil cylinders. The height adjustment bracket includes a horizontal part extending along the left and right direction and a vertical part erecting the horizontal part. The front part of the horizontal part is provided with the upper connection point of the elevation cylinder, and the middle part of the horizontal part is provided with the upper connection point of the tractor three-point suspension mechanism. The rear part of the horizontal part is provided with the front connection point of the upper tie rod, the lower inner part of the longitudinal part is provided with the connection point of the lower lifting bracket, and the lower part of the longitudinal part is provided with the lower connection point of the tractor three-point suspension mechanism, and the elevation adjustment bracket is...

Embodiment 2

[0042] This embodiment adopts the continuous height adjustment mechanism of the implement in the first embodiment, which is installed between the three-point suspension mechanism of the tractor and the rotary cultivator. This embodiment adopts a laser control system.

[0043] Figure 5 As shown, it mainly includes a tractor, a continuous height adjustment mechanism for implements, a rotary tiller, a hydraulic valve group, a controller, a laser receiver mounting rod, and a laser transmitter.

[0044] A method for automatically adjusting the depth of tillage with a continuous height adjustment mechanism for implements. During operation, due to the unevenness of the farmland surface, the front and rear wheels of the wheeled tractor are not on the same level during field operations, resulting in the height of the rotary tiller relative to the field surface. Because the pitch of the tractor changes at any time, the laser receiver installed on the receiver mounting rod senses the l...

Embodiment 3

[0046] This embodiment adopts the continuous height adjustment mechanism of the equipment in the first embodiment, which is installed between the three-point suspension mechanism and the rotary tiller. In this embodiment, an ultrasonic ranging sensor control system is adopted.

[0047] Image 6 As shown, it mainly includes tractor, implement height continuous adjustment mechanism, rotary tiller, hydraulic valve group, controller and ultrasonic distance measuring sensor (two, one on the left and one on each side).

[0048] A method for automatically adjusting the depth of tillage of a machine tool elevation continuous adjustment mechanism. During operation, the rotary tillage depth of the rotary tiller is first set, and the average value of the distance from the ground measured by the two ultrasonic distance measuring sensors at this time is recorded. 0 , due to the uneven potholes on the farmland surface, the front and rear wheels of the wheeled tractor are not on the same le...

Abstract

The invention relates to a continuous machine elevation adjusting mechanism and belongs to the technical field of agricultural tilling and land preparation machines. The mechanism comprises an elevation adjusting support, a lower lifting support, an upper pull rod and an elevation oil cylinder, wherein the elevation adjusting support comprises a transverse part extending bilaterally and a longitudinal part for erecting the transverse part; the connecting point of the upper pull rod and a machine, the connecting point of the upper pull rod and the elevation adjusting support, the connecting point of the lower lifting support and the elevation adjusting support and the connecting point of the lower lifting support and the machine form a parallelogram, so that the machine, the upper pull rod,the elevation adjusting support and the lower lifting support constitute a parallelogram mechanism. The invention also relates to an automatic tilling depth adjusting method of the continuous machineelevation adjusting mechanism. By means of the mechanism, the operation quality and the operation efficiency can be improved, and damage to a tractor and the machine due to overload flameout in the operation process of the machine can be reduced.

Description

technical field [0001] The invention relates to an agricultural plowing and land preparation machine tool, in particular to a machine tool elevation continuous adjustment mechanism and an automatic adjustment method for the tillage depth. Background technique [0002] The stability of tillage depth is the main performance index of the operation quality of tillage agricultural machinery (rotary tiller, plow, etc.). Due to the unevenness of the farmland, the working depth of the machinery changes with the pitch and inclination of the tractor, and the working depth of the machinery can be determined by The tractor adjusts the settings, but it is easy to plow deep in the low-lying areas of the farmland and shallow in the high areas, resulting in poor plowing effects and low operation efficiency, and damage to the hard bottom of the farmland, and it will also affect the flatness of the machine after plowing. Although these problems can be reduced or alleviated by manually adjusti...
