Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and more specifically, to an electro-hydraulic steering device for agricultural machinery. Background Art

[0002] Planting is one of the main components of agriculture. It is generally a process of using the life functions of plants themselves to obtain food, non-staple food, feed and industrial raw materials through artificial cultivation. In the past, agricultural planting was generally carried out by manpower. This planting method not only has a low rate, but also greatly increases the pressure on growers. With the rapid development of society, a variety of machinery used in the agricultural planting industry has emerged, which are generally referred to as agricultural machinery.

[0003] The steering device is one of the indispensable components in agricultural machinery, and there are many types of steering devices, among which the electro-hydraulic steering device is also one of the steering devices. When most of the existing electro-hydraulic steering devices are installed, they are generally directly installed in a suitable installation position by means of bolts and soft pads. Although this installation method is relatively convenient, the soft material of the soft pad will soften after long-term use and cause the bolt tightening force to decay, which is often called the torque decay of the soft connection. The torque decay can easily cause the electro-hydraulic steering device to become loose at its installation position, causing the electro-hydraulic steering device to be unable to be used normally. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an electro-hydraulic steering device for agricultural machinery, which realizes the installation of the electro-hydraulic steering device body by cooperating with a first mounting mechanism and a second mounting mechanism, and can effectively avoid the phenomenon of torque attenuation after the bolts are tightened, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electro-hydraulic steering device for agricultural machinery, comprising an electro-hydraulic steering device body, a plurality of first mounting mechanisms being arranged at the bottom of the electro-hydraulic steering device body, and a second mounting mechanism being arranged at the top of the electro-hydraulic steering device body.

[0006] In a preferred embodiment, the first mounting mechanism includes a first anti-slip ring, a first connecting ring is provided inside the first anti-slip ring, and an annular groove is provided on the outer wall of the first anti-slip ring.

[0007] In a preferred embodiment, a pressure ring is provided inside the annular groove, a washer is provided at the bottom of the pressure ring, and a bolt is provided at the bottom of the washer.

[0008] In a preferred embodiment, the second mounting mechanism includes a second anti-slip ring, the inner wall of the second anti-slip ring is provided with two slots, each of the two slots is provided with a block, and a third anti-slip ring is provided between the two blocks.

[0009] In a preferred embodiment, a plurality of through holes are opened inside the second anti-slip ring, and a second connecting ring is provided inside each of the plurality of through holes.

[0010] In a preferred embodiment, a plurality of positioning grooves are formed at the bottom of the third anti-slip ring, and positioning blocks are provided inside the plurality of positioning grooves.

[0011] The technical effects and advantages of this utility model are:

[0012] By cooperating with each other, the first mounting mechanism and the second mounting mechanism enable the bolts to be tightened by contacting the first connecting ring rather than being screwed into the corresponding position by directly contacting the soft component when the electro-hydraulic steering device body is installed using bolts. The second connecting ring enables the electro-hydraulic steering device body to have both soft and hard contact functions. This effectively prevents the soft material from softening after long-term use, which would cause the bolt tightening force to weaken and torque to decay. This effectively prevents the electro-hydraulic steering device body from loosening easily after being tightened by bolts in its installation position, thereby preventing the electro-hydraulic steering device body from being unable to be used normally. This installation method significantly improves the reliability of the electro-hydraulic steering device body after installation, thereby significantly improving the practicality of the device. By positioning the third anti-slip ring with the positioning block and clamping the second anti-slip ring to the outer wall of the third anti-slip ring with the clamping block, the position of the second mounting mechanism can be easily limited at the top of the electro-hydraulic steering device body, facilitating the installation of the electro-hydraulic steering device body in conjunction with a plurality of first mounting mechanisms.
