Description

Technical Field

[0001] The invention relates to the technical field of forestry seedling cultivation, in particular to a trail ditch weeder. Background Art

[0002] After sowing or changing the bed in spring, the seedbed can basically maintain a shape and specifications similar to the standard seedbed. However, after the impact of summer rain and the trampling of people and machines, the trail ditch will become shallower and shallower, the soil will become harder and harder, and weeds will grow. This phenomenon makes it difficult for the nursery soil to retain moisture when encountering dry weather; and in flooded weather, the nursery land will become a vast ocean, which is not conducive to the growth and development of seedlings.

[0003] To address the problems of soil hardening, weed growth, and poor drought and flood control in the nursery's trail ditches caused by rainwater erosion and human and machine pressure, timely soil loosening and weeding are necessary. Loosening and weeding the trail ditches help excess water in the nursery seep into the ground, facilitate autumn mulching to protect against cold, and benefit the growth and development of the seedlings. Given that the trail ditches are typically designed to be 600mm wide, hand-push tillers are commonly used for loosening and weeding. However, traditional hand-push tillers have limited single-operation range and slow speed. Summary of the Invention

[0004] In view of the problems of small single operation range and slow working speed of the above-mentioned traditional hand-push tillers, the purpose of the present invention is to provide a trail ditch weeder. The present invention overcomes the design technology of narrow shovel-type furrowing device and sorghum double-sided operation structure, and realizes soil fragmentation and weed removal through the synchronous furrowing and soil breaking of double loosening shovels and rotary tillage and soil crushing device, solving the problem of water seepage imbalance caused by the collapse of trail ditches in traditional nurseries and the decreased survival rate of seedlings due to exposed roots of seedlings on both sides of the seedbed due to lack of soil. The equipment increases the soil water holding capacity by 40% and the weeding efficiency by 98%, realizing the ecological regulation of the nursery of "retaining moisture in drought and seeping water in floods", solving the problem of soil lack on both sides of the seedbed, and improving the survival rate of seedlings on both sides of the seedbed. The comprehensive operation efficiency is 3 times higher than that of the traditional method, with the advantages of low cost, easy operation and strong stability.

When the height needs to be adjusted, the top screw can be loosened.

[0050] Working principle:

[0051] During weeding and loosening operations, the tractor's power output transmits power to the transmission box 3 via the drive shaft 1, which then drives the rotary tillage assembly 4, thereby breaking up the soil and weeds in the trail ditch. Specifically, the tractor's power output provides power to drive the drive shaft 1, which drives the input shaft 305. The input shaft 305 drives the output shaft 308 through meshing. The output shaft 308 drives two couplings 10. Each coupling 10 drives a shaft 402. The shaft 402 drives a first sprocket 403. The first sprocket 403 drives a second sprocket 405 via a chain 404. The second sprocket 405 drives a rotary tiller shaft 406. The rotary tiller shaft 406 drives a rotary tiller blade 407.

[0052] When the tractor pulls the trail ditch weeding and loosening machine, the trail plows 5 on both sides dig trenches and break the hard soil of the two trail ditches respectively, the multiple rotary tillers 407 on both sides weed and loosen the soil of the two digged trail ditches respectively, and the shovels 602 on both sides level the two plowed trail ditches respectively.

[0053] The soil loosening depth can be adjusted by the hydraulic cylinder at the rear of the tractor, and the rotation speed of the rotary tiller shaft 406 can be adjusted by controlling the output power of the tractor throttle to achieve a good soil crushing effect.

[0054] Directions:

[0055] Before use, connect the trail ditch weeding and tilling machine to the tractor through the main frame 2, adjust the connecting rods of the tractor suspension frame to make the trail ditch weeding and tilling machine in a horizontal state, and use the power provided by the tractor to drive the rotary tillage component 4 to complete the weeding and loosening operation.

[0056] Notes:

[0057] Before use, check whether the transmission box 3 and sprocket transmission of this trail ditch weeder need to be lubricated to ensure that they are well lubricated; before use, check whether all bolts are loose and ensure that all bolt connections are securely fastened; before operation, adjust the connecting rods on the tractor suspension frame to make this trail ditch weeder in a normal horizontal position; when the machine is not in operation, be sure to lift this trail ditch weeder to avoid damage to the machine; the rotary tillage blade 407 is a wearing part and should be checked in time for damage or loss during use. If so, it should be replaced with a spare part in time to ensure normal operation of the machine; when the machine is not in use for a long time, all lubrication parts should be filled with lubricating oil to avoid rusting of the machine.

[0058] The main seedbed specifications and technical parameters of the present invention are detailed in the table below:

[0059]

[0060] In summary, the main frame 2 of the present invention spans above the seedbed, and is connected to trail plows 5 and rotary tillage components 4 on both sides, which can operate on the trail ditches on both sides of the seedbed simultaneously. The trail plow 5 is a narrow shovel-type trenching and soil-breaking device. The trail plow 5 ditches and breaks the hard soil of the trail ditch, and the rotary tillage component 4 crushes and loosens the weeds and soil. The trail ditch after loosening the soil and weeding is conducive to the infiltration of excess water in the nursery into the ground, and is more conducive to the autumn cold-proof soil covering operation, which is beneficial to the growth and development of seedlings. This trail ditch weeder has the advantages of low cost, easy operation, stable performance, and efficient soil loosening and weeding.

[0061] In addition, two soil-supporting blades 6 are mounted on the main frame 2 of the present invention. The two soil-supporting blades 6 are located behind the two rotary tillage assemblies 4. The soil-supporting blades 6 are used to level the turned-up soil, thereby preventing the seedbeds on both sides of the trail ditch from sliding. The present invention simultaneously performs soil breaking, loosening, weeding, and leveling, thereby improving operational efficiency.

[0062] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
