Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a rotary tillage device of a micro-tillage machine with a profiling function. Background Art

[0002] my country is the world's largest tea-growing country, with tea plantations accounting for about one-third of the world's total area, and tea production also ranks first in the world. However, there may be many problems in the process of tea plantation cultivation, especially in tea plantation management, including arable land, fertilization, irrigation and other aspects. If the land is not well managed, the land will be uneven and overgrown with weeds, which will affect the normal growth of tea trees and the quality of tea. In addition, there is currently no suitable rotary tillage device widely used in production for depressions and slopes in tea gardens. Common tea garden tillage machinery currently includes traditional plowing and tillage machinery, which use a single tool for soil treatment, which is time-consuming, labor-intensive and inefficient.

[0003] Among them, the patent document with publication number CN117882512A discloses a garden management machine with a slope profiling function, including a support frame, a driving handle, a rotating shaft, a first universal joint, a second universal joint, a rotary tillage roller, an adjustment plate, a telescopic member, a screw rod, a transmission shaft, a transmission wheel, a pulley, etc. By setting the adjustment component, the angles of the two rotary tillage rollers are adjusted to meet the rotary tillage and land preparation work on different slopes, and the rotary tillage rollers can also be buffered to prevent damage during work, which solves the problem that the rotary tillage rollers in the existing equipment are usually installed at a fixed angle, so that the rotary tillage and land preparation work on different slopes cannot be met, thereby improving the efficiency of the tillage and land preparation work;

[0004] However, when the above-mentioned prior art is in operation, the machine still needs to be manually held to move forward. The operation of the farmland management machine with the slope profiling function is relatively complicated, and the operator needs to have a higher level of skills and operating experience. Although the adaptability of the machine on complex terrain is improved, there are still some terrain limitations. For example, it may not be able to operate effectively on terrain that is too steep or irregular. Moreover, the existing micro-tillage machine can only play a rotary tillage role, and cannot apply fertilizer, which cannot meet people's usage needs. Summary of the invention

[0037] The driving component 4 includes a chassis 45, a gear box 43 is movably installed at the inner center of the chassis 45, a driving shaft 42 is rotatably clamped in the middle of the gear box 43, a driving motor 46 rotatably connected to the driving shaft 42 is fixedly installed at one end of the inner part of the chassis 45, transmission wheels 41 are arranged on both sides of the inner part of the chassis 45, support wheels 47 are arranged on both sides of the outer part of the chassis 45, tracks 44 are sleeved on the outer surface of the support wheels 47, and a second hydraulic cylinder fixedly connected to the top of the gear box 43 is fixedly installed at the inner top center of the chassis 45.

[0038] The top of the first hydraulic cylinder 12 and the electric push rod 28 of the present invention are rotatably connected to the bottom surface of the limit top plate 37 through the hinge seat 311, so that the first rotary tillage component 1 and the transmission component 2 can be suspended and limited. One end of the connecting arm 11 is rotatably connected to the side of the covering plate 34 through the limit rod 312, so that the covering plate 34 can follow the rotary tillage blade 14 to rise and fall, so that the rotary tillage soil can be adapted and leveled.

The second power transmission shaft 32 is meshed and connected with one end of the bevel gear rod 33 through the second bevel gear at one end, so as to control the synchronous rotation of the two sets of bevel gear rods 33. The top interior of the corrugated conduit 31 is connected to the inner bottom end of the fertilizer box 36, and the groove 35 on the outer surface of one end of the bevel gear rod 33 is aligned with the top of the corrugated conduit 31, so as to transport the fertilizer below. The top sliding card sealing sliding cover of the fertilizer box 36 can prevent the fertilizer inside the fertilizer box 36 from overflowing. A pulling spring is arranged inside the telescopic sleeve 310, so as to make the covering plate 34 deflect up and down to avoid rigid impact.

[0040] The second drive motor is arranged on both sides of the interior of the chassis 45 of the present invention, and the transmission wheel 41 is connected to the second drive motor on the side of the chassis 45, so as to drive the crawler 44 to rotate. The telescopic operation of the two sets of electric push rods 28 will drive the angle of the two sets of rotary tillers 14 to change within a range of 150°~180°, and when the operating extension amount of the first hydraulic cylinder 12 is 30 mm, the maximum deflection angle of the rotary tiller 14 is 30°, so that rotary tillage can be carried out in tea gardens with different terrains to meet people's usage needs.

[0041] The working principle of the present invention is as follows: before using the micro-tillage machine to perform rotary tillage on the tea garden, the overall height of the gear box 43 is first adjusted by controlling the second hydraulic cylinder to meet the adjustment requirements of the first rotary tillage component 1;

[0042] During this process, the driving motor 46 is first started to drive the driving shaft 42 to rotate, so that it drives the power transmission rod 26 to rotate. At the same time, the power transmission rod 26 will drive another group of power transmission rods 26 to rotate synchronously through the first power transmission shaft 25 inside the protective shell 29. The transmission component 2, as the central connection between the first rotary tillage component 1, the driving component 4 and the second rotary tillage component 5, will follow the lifting and lowering of the gear box 43, bend and change shape, so as to adapt to the transmission requirements of different heights and angles; therefore, when the first rotary tillage component 1 and the second rotary tillage component 5 are in contact with the ground and run, they will change with the change of the terrain, avoiding the phenomenon that the straight-axis drive causes different tillage depths;

[0043] When using the micro-tillage machine to rotary till the tea garden, the operator needs to rotatably connect the front end of the limit top plate 37 with the driving component 4, and then connect the top end of the power transmission rod 26 on one side of the protective shell 29 with one end of the driving shaft 42 to ensure that its power is appropriate, and then check each component one by one to ensure that they are in good condition, safe and reliable, and have been prepared;

[0044] Before driving the component 4, the operator should first make a preliminary assessment of the surrounding working environment to ensure the continuation of subsequent operations, and adjust the working parameters of the equipment, such as tillage width, depression depth and ramp angle, according to the actual field conditions and operating requirements;

[0045] Then, the driving motor 46 is started to drive the driving shaft 42 to rotate, and at the same time, the second driving motor is started to drive the supporting wheel 47 to rotate synchronously through the transmission wheel 41, and the supporting wheel 47 will drive the crawler 44 to rotate, so that the driving component 4 as a whole starts to drag the fertilizing component 3 forward, and at the same time, the driving shaft 42 will drive the first power transmission shaft 25 to rotate synchronously through the power transmission rod 26 connected at the end, so that the first power transmission shaft 25 drives the helical gear shaft 22 meshing at the bottom to rotate synchronously through the first helical gear 21 on the outer surface, and at the same time, the helical gear shaft 22 drives the helical gear transmission column 24 meshing at the bottom to rotate synchronously, so the helical gear transmission column 24 will drive the two sets of rotary tilling blades 14 to rotate synchronously through the universal transmission shafts 23 at both ends, so that the rotary tilling blade 14 drives the rotary tilling blade 13 on the outer surface to rotary till the ground;

[0046] In the initial stage, the operator needs to accurately judge the rotary tillage position and evaluate the working environment, and appropriately adjust the height of the protective shell 29 and the angles of the first rotary tillage component 1 and the second rotary tillage component 5. When encountering a depression, the first hydraulic cylinder 12 contracts upward, so that one end of the rotary tillage blade 14 is lifted up by a certain angle, so that the rotary tillage blade 13 on the outer surface of the rotary tillage blade 14 can fully till the soil during operation; when encountering a ramp, the electric push rod 28 contracts upward to drive the protective shell 29 to lift up, and at the same time the protective shell 29 will lift the ends of the two groups of rotary tillage blades 14, so that the rotary tillage blades 13 can till the soil well, and the machine can pass the ramp smoothly. Among them, when the micro-tillage machine is performing rotary tillage work, when fertilization is needed, fertilizer can be added to the inner part of the fertilizer box 36 Then, when the driving component 4 is running, the power transmission rod 26 will drive the second power transmission shaft 32 at one end to rotate synchronously. When the second power transmission shaft 32 rotates, the second bevel gear will drive the two sets of bevel gear rods 33 meshing at one end to rotate synchronously, so that one end of the bevel gear rod 33 rotates inside the fertilizer box 36. At the same time, the groove 35 on the outer surface of the end of the bevel gear rod 33 will drive the fertilizer box 36 to turn the fertilizer downward, so that the fertilizer is discharged into the fertilizer discharge pipe 38 through the corrugated conduit 31, and the electric push rod 28 is driven by the covering plate 34 to press down into the soil after rotary tillage. Therefore, when the fertilizer discharge pipe 38 moves in the soil, it will discharge the fertilizer into the soil after rotary tillage, thereby achieving the effect of fertilization;

[0047] When the soil treatment operation of the entire tea garden is completed, turn off the crawler tiller, stop the device, and perform necessary cleaning and maintenance work to ensure the smooth progress of the next operation; after the soil treatment operation is completed, the device will be properly kept and wait for the next operation to start;

[0048] Through this set of rotary tillage process, the device of the present invention can efficiently complete the soil treatment work in the tea garden. It can not only achieve a good rotary tillage effect, but also reduce the frequency of rotary tillage of the machine and minimize the damage to the tea garden. This soil treatment operation method causes little damage to the tea garden, reduces power consumption, has high work efficiency, and can effectively solve the problem of poor operation quality of traditional rotary tillage machines.

[0049] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
