Problems solved by technology
[0003] However, the existing soil renovation technology usually uses agricultural machinery to pull various soil-turning equipment for soil damage and leveling; due to the large amount of water storage in the farmland soil, the existing traction equipment cannot walk on this type of land due to its own quality problems. Impossible to carry out mechanized improvement;
[0004] At present, the common traction machines on dry land adopt steel structure chassis with driving wheel and guide wheel structure. The driving wheel and guide wheel are in direct contact with the soil. Due to the high pressure, the machine with this structure is placed in a place with a large water storage capacity. After being in the soil, it will be stuck in a situation where it is impossible to walk, and at the same time, the muddy water resistance is small, and accurate steering cannot be achieved; there are a small number of crawler traction machines suitable for muddy soil on the market, but this kind of machine walks slowly on dry land and requires independent power Mechanism, the mechanism is complicated, and it is easy to cause damage to the road, so it is not applicable. Therefore, the present invention provides a multi-road condition agricultural machinery chassis

Embodiment approach
[0037]As a preferred embodiment of the present invention, the lifting power device 11 is composed of a hydraulic cylinder 111 and a piston rod 112 penetrating through the hydraulic cylinder 111. The top of the piston rod 112 is welded to the trigger power plate 14. The traction block, the bottom of the piston rod 112 is welded with an inverted V-shaped frame, the side wall of the fixed mounting plate 12 is welded with a matching shaft 121, and the inverted V-shaped frame and the traction block are welded with a matching shaft 2 1121, the second matching shaft 1121 is equipped with a supporting gear 11211 internally meshing with the crawler belt 13 through a bearing, and the first matching shaft 121 is equipped with a supporting gear 11211 internally meshing with the crawler belt 13 through a bearing. Driven by the hydraulic cylinder 111, it has sufficient power and stability. When walking in soil with a large water storage capacity, the hydraulic cylinder 111 drives the piston ...

The invention discloses a multi-road condition agricultural machinery chassis, comprising: a lifting crawler combination, a composite guide driving wheel combination, a reversing connecting rod and a chassis fixing combination; wherein, the lifting crawler combination includes a lifting power device, a fixed mounting plate, a crawler One end is hinged to two trigger power plates on the top of the lifting power device and two rotatable grooved slide plates arranged on the fixed mounting plate, and the lifting power device is fixed to the middle of one side of the fixed mounting plate by bolts, And located between the two grooved slide plates, the trigger power plate is nested in the grooved slide plates and can slide relatively. The present invention is that the lifting crawler combination has the function of lifting and lowering the crawler, and the lifting of the crawler from the ground can adapt to walking on the hard ground, avoiding the damage of the road by the crawler, moving the crawler down to touch the ground, and increasing the contact area between the chassis and the ground, thus improving the The pressure of the mechanical chassis is suitable for walking on farmland with a large water storage capacity.
Description
technical field [0001] The invention relates to the technical field of agricultural engineering machinery chassis, in particular to a multi-road condition agricultural machinery chassis. Background technique [0002] In the south of my country, due to the influence of seasons, most of the farmland is mainly planted with rice. In order to improve the fertility and soil environment of the farmland soil with a large water storage capacity, it is necessary to use farmland machinery for soil renovation; [0003] However, the existing soil renovation technology usually uses agricultural machinery to pull various soil-turning equipment for soil damage and leveling; due to the large amount of water storage in the farmland soil, the existing traction equipment cannot walk on this type of land due to its own quality problems. Impossible to carry out mechanized improvement; [0004] At present, the common traction machines on dry land adopt steel structure chassis with driving wheel a...
