Description

Technical Field

[0001] The utility model relates to the technical field of tillage equipment, in particular to a ditching and land leveling device and a four-wheel riding micro-tillage machine. Background Art

[0002] The main function of trenching in cultivated land is to store water, conserve soil, and prevent wind. In order to save manpower, in the existing farming method, the trenching equipment is generally towed to the rear end of the micro-tillage machine. Since the trenching equipment includes a conical plowshare that is small in front and large in the back, when dragged by the micro-tillage machine, the soil near the plowshare will be pushed to both sides to form a trench, and a ridge will be formed between the trenches.

[0003] However, when some crops are planted more densely or require irrigation and fertilization, in order to ensure that fertilizer and water are evenly distributed, it is necessary to ensure that the ridges are flat. In the above-mentioned furrowing method, since the soil is pushed to the side by the plow head, the soil accumulates in the area near the ditch and the height is relatively high. After the furrowing is completed, it is necessary to use a leveling harrow to level the soil, which reduces the farming efficiency. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a trenching and leveling device that can perform trenching and leveling at the same time.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A furrowing and ground leveling device comprises a furrowing plow. Both sides of the furrowing plow are provided with ground leveling harrows, and the ground leveling harrows are located in the middle or rear end of the furrowing plow.

[0007] Working principle: Under the drag of the four-wheel ride-on micro-tillage machine, the front end of the furrowing plow plays the role of spreading the soil, and the part from the middle to the rear end plays the role of maintaining the shape of the furrow. Therefore, a leveling harrow is set in the middle or rear end to level the spread soil.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] By setting leveling harrows on both sides of the furrowing plow, furrowing and leveling are carried out at the same time, which improves the farming efficiency compared with the traditional method of furrowing first and then leveling.

[0010] As a preferred embodiment of the present invention, a mounting assembly is provided at the top of the furrowing plow, and the two leveling harrows are detachably connected to both ends of the furrowing plow mounting assembly.

[0011] Beneficial effect: by providing a detachable leveling harrow, in a farming environment where leveling is not required, only the leveling harrow can be disassembled without replacing a new furrowing tool, which is more convenient to use.

[0012] As a preferred embodiment of the present invention, the mounting assembly includes a fixed sleeve, and each leveling rake is provided with an insertion rod that can be inserted into the fixed sleeve at one end, and two adjustment screws that can tighten the insertion rod are screwed on the outer wall of the fixed sleeve.

[0013] Beneficial effects: The installation is carried out by inserting the insertion rod into the fixed sleeve, and the assembly and disassembly are quick; and the insertion depth can be adjusted to adjust the tillage position of the leveling harrow on both sides, and the rotation angle of the insertion rod can be adjusted to adjust the tillage depth of the leveling harrow in a small range.

[0014] As a preferred embodiment of the present invention, two connecting plates are provided on the fixed sleeve, and the two connecting plates are respectively welded to the two inner walls of the furrowing plow.

[0015] Beneficial effect: By setting two connecting plates and welding them to the two inner walls of the furrowing plow, since the overall shell of the furrowing plow is relatively thin, it will be subjected to inward squeezing force during the furrowing process, and the connecting plates and the fixed sleeve support the inner wall, thereby improving the overall structural strength.

[0017] Beneficial effect: By setting the adjustment component, the rotation angle of the rotating frame is adjusted, thereby changing the height of the furrowing plow and the leveling harrow.

[0018] As a preferred embodiment of the present invention, the adjustment assembly includes a connecting sleeve and an adjusting rod. The connecting sleeve is fixedly mounted on a fixed frame. A thread is provided in the connecting sleeve. The adjusting rod is threadedly connected to the connecting sleeve. The lower end of the adjusting rod is hinged with a lifting frame. When the adjusting rod rotates, the rotating frame is lifted or lowered by the lifting frame.

[0019] Working principle: After rotating the adjusting rod, due to the screw connection with the connecting sleeve, the adjusting rod will pass through the hinged lifting frame to raise or lower the rotating frame to adjust the tillage depth.

[0020] As a preferred embodiment of the present invention, the rotating frame includes a horizontal frame and a vertical plate, the lower part of the vertical plate is fixedly connected to the furrowing plow, the upper part of the vertical plate is provided with a plurality of through holes spaced apart along the length direction, and a rectangular frame is provided at one end of the horizontal frame, the vertical plate can pass through the rectangular frame, and the rectangular frame is fixedly connected to the corresponding through holes by screws.

[0021] Beneficial effects: By providing a vertical plate with multiple through holes, the height of the tillage tool can be adjusted when assembling the tillage tool, and other types of tillage tools can be installed through the vertical plate, which has a wider range of applications.

[0022] The second purpose of the present utility model is to provide a four-wheeled riding micro-tillage machine, which adopts the above-mentioned ditching and leveling device to simultaneously complete ditching and leveling, thereby achieving high tillage efficiency.
