Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an improved mud guard structure of a rotary cultivator comprises an installation frame 1, a colter shaft 2 is movably sleeved in an inner cavity of the installation frame 1, a transmission case body 3 is fixedly installed at the top of the right side of the outer portion of the installation frame 1, the inner portion of the transmission case body 3 is in transmission connection with one end of the colter shaft 2, a transmission case body 4 is fixedly installed at the top of the installation frame 1, the inner portion of the transmission case body 4 is in transmission connection with the inner portion of the transmission case body 3, a carriage 5 is connected to one side of the outer portion of the installation frame 1 in a pin joint mode, the front face of the carriage 5 is in transmission connection with the top end of the installation frame 1 through an installation connecting rod 6, and a.

Wherein, to the setting of installation connecting rod 6 and pressure spring 7 on planker 5, when utilizing planker 5 to come the separation soil that splashes, can utilize pressure spring 7's elasticity to exert a decurrent pressure to it, level the soil after the rotary tillage to in the later stage carry out the seeding operation on the level soil.

In this technical scheme, the both ends of coulter shaft 2 just are equipped with a set of collar 8 respectively among being located the inner chamber of installation frame 1, the bottom mounting of collar 8 has elastic sleeve 9, and elastic sleeve 9's bottom fixed mounting has support ring 10, one side swing joint of support ring 10 has fixed sleeve 12, the middle part fixed mounting of installation frame 1 inner chamber one side has fixed sleeve 12, and fixed sleeve 12's inside activity has cup jointed transmission connecting rod 13, through the meshing transmission of drive gear 14 between support ring 10 and the fixed sleeve 12, the one end of transmission connecting rod 13 is connected with the bottom pin of planker 5 one side.

When the rotary cultivator does not work and is lifted, the planker 5 is always in a vertically downward state under the action of gravity, so that the support ring 10 is ensured to be positioned below the colter shaft 2, and a good protection is formed on the colter shaft, so that the rotary cultivator cannot bump between the colter shaft 2 and a paved road surface due to height difference when the rotary cultivator spans the paved road surface;

when the rotary cultivator starts to work and is arranged below, the dragging plate 5 is slowly lifted to one side under the extrusion action between the dragging plate 5 and the ground, and then under the action of a series of transmission, the support ring 10 is anticlockwise moved to the middle position of one side of the colter shaft 2, so that the bottom of the colter shaft 2 is exposed and is in contact with soil to carry out rotary cultivation operation, and the application range of the rotary cultivator is effectively enlarged.

In the technical scheme, the middle part of one side of the carriage 5 is in threaded connection with a support connecting rod 15, the top of the outer surface of the support connecting rod 15 is movably sleeved with a balance spring 16 below one side of the carriage 5, and a balance air bag 17 is fixedly installed at the bottom end of the support connecting rod 15.

In this technical solution, the inner cavity of the balancing airbag 17 is filled with a full volume of inert gas.

Wherein, to the setting of support link 15, balance spring 16 and balanced gasbag 17, because the rotary cultivator is the amphibious type, and the bearing capacity of soil between nonirrigated farmland and the paddy field is different, if adopt the same pressure to come the soil on the level and smooth paddy field, then can lead to the compactness of soil in the paddy field too high, and then serious seeding and the growth that has influenced aquatic crops, so, utilize the buoyancy of balanced gasbag 17 can adjust the pressure of planker 5 to soil in the paddy field effectively, when guaranteeing that planker 5 carries out the leveling operation to soil in the paddy field, can not cause the higher problem of compactness of soil after the rotary tillage because of pressure is too big.

In the technical scheme, the included angle between the two ends of the transmission ring gear 11 is less than 180 degrees, and the gear block on the transmission ring gear 11 is positioned obliquely above the outer surface of the transmission ring gear.

The included angle between the two ends of the transmission ring gear 11 is set so that after the transmission ring gear rotates anticlockwise to a certain angle along with the planker 5, the colter shaft 2 can be effectively exposed to be in contact with the ground without causing extrusion phenomenon between the transmission ring gear 11 and the ground.

The use method and the working principle of the embodiment are as follows:

when the rotary cultivator is in a dry land and is ready to work to lower the colter shaft 2, the bottom end of the planker 5 is firstly contacted with the ground and is extruded, the pressure spring 7 is compressed under the transmission action of the mounting connecting rod 6, so that a certain pressure is kept between the bottom end of the planker 5 and the soil on the ground, meanwhile, when the planker 5 inclines outwards due to the extrusion of the ground, the transmission gear 14 is driven to rotate and the transmission ring gear 11 is driven to rotate anticlockwise under the connecting rod transmission action of the transmission connecting rod 13, so that the support ring 10 is driven to move to the side surface of the colter shaft 2, the bottom end of the colter shaft 2 is gradually exposed and contacted with the ground so far, and the rotary cultivation operation is carried out on the soil;

when the rotary cultivator is positioned in a paddy field and prepares to work with the colter shaft 2 below, the steps are repeated, and the balance air bag 17 is influenced by buoyancy due to contact with the water surface in the paddy field, so that the inclination angle of the carriage 5 is increased, the pressure between the bottom end of the carriage and the soil in the paddy field is reduced and controlled, and the problem of overhigh soil compactness in the paddy field due to overhigh pressure is solved;

when the rotary cultivator needs to cross a paved road surface and move to other fields, the colter shaft 2 is lifted, the carriage 5 can be separated from the ground, and the carriage is kept in a vertical state under the action of impact force, the support ring 10 rotates clockwise to the position below the colter shaft 2 under the linkage action of the transmission ring teeth 11, the transmission connecting rod 13 and the transmission gear 14, so that the colter shaft 2 can not collide with the paved road surface when the rotary cultivator crosses the paved road surface and the fields with certain height difference, the knife edge of the colter on the colter shaft 2 is effectively protected, the problem that the paved road surface is damaged is avoided, and the adaptability of the rotary cultivator is effectively improved.
