Description

Technical Field

[0001] The utility model belongs to the technical field of rotary tillers, and in particular relates to an adjustable fertilizing rotary tiller. Background Art

[0002] A rotary tiller is a tilling machine that is used with a tractor to complete ploughing and harrowing operations. It is widely used because of its strong soil crushing ability and flat surface after ploughing. It can also cut up the root stubble buried below the surface, making it easier for the seeder to operate and providing a good seed bed for later sowing. It is divided into two types according to the configuration of its rotary tiller blade: horizontal axis type and vertical axis type.

[0003] However, no matter it is a horizontal axis type or a vertical axis type, the adjustment method is to adjust in the horizontal direction, and the inclination angle cannot be changed, so it cannot be well adapted to the cultivation of the soil with a slope and a trapezoidal shape. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide an adjustable fertilizing rotary tiller.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An adjustable fertilizer rotary tiller comprises a mounting plate, wherein the mounting plate is mounted on a first telescopic cylinder, and an output end of the first telescopic cylinder is connected to a lifting plate;

[0007] A motor, a pump, a water tank and a second telescopic cylinder are installed on the upper side of the lifting plate, and a bracket is installed on the lower side of the lifting plate;

[0008] The output end of the motor is connected to a rotating shaft, and the output end of the rotating shaft is connected to a first ball gear. A support rod is rotatably installed on the bracket, and a fixing ring is installed at the center of the support rod. A bearing is installed in the fixing ring, and a rotary tillage rod is fixedly installed on the inner ring of the bearing. A second ball gear meshing and matching with the first ball gear is fixedly connected to the end of the rotary tillage rod, and an inner cavity is provided inside the rotary tillage rod. The rotary tillage rod is evenly provided with a plurality of nozzles connected to the inner cavity, and a plurality of rotary tillage knives are installed on the outside of the rotary tillage rod. A rotating box is rotatably installed on the outside of the rotary tillage rod, and the output end of the rotating box corresponds to the nozzle. A hose is connected between the input end of the rotating box and the output end of the pump, and the input end of the pump is connected to the water tank. An end head is rotatably installed on the other end of the rotary tillage rod, and the end head is provided with a T-shaped groove, and a T-shaped slider hinged to the output end of the second telescopic cylinder is slidably installed on the T-shaped groove.

[0009] It is further defined that the bracket is installed with a limit rod, and such a design limits the hose to a side away from the rotary tiller to prevent interference.

[0010] It is further defined that a first bearing seal ring and a second bearing seal ring are installed in parallel on the outer side of the rotary tiller rod, and the rotating box is installed between the first bearing seal ring and the second bearing seal ring. Such a design ensures that the liquid is transmitted into the inner cavity while ensuring the rotation effect of the rotating box and the sealing effect of the liquid.

[0011] It is further defined that the lifting plate is provided with a protective tube located at the output end of the second telescopic cylinder. Such a design protects the output end of the second telescopic cylinder, reduces its bearing effect, and ensures the use effect.

[0012] It is further defined that the lifting plate is connected to a guide rod slidably mounted on the mounting plate. Such a design ensures that the lifting plate can be lifted and lowered smoothly.

[0013] The beneficial effects of adopting the utility model are:

[0014] By adopting the structural design of the utility model, the rotation of the rotary tillage rod about the axial position of the support rod can be realized by controlling the operation of the second telescopic cylinder, thereby realizing the inclination of the rotary tillage rod. At the same time, under the meshing cooperation of the first ball gear and the second ball gear, the rotation of the rotary tillage rod will not be affected, so that while achieving tillage with an angle, some special staggered tillage methods can also be realized, that is, soil of different depths can be cultivated at one time, so as to facilitate comparative experiments on the influence of soil depth on crops.
