[0002] In agricultural planting production, trenching is an indispensable process in field cultivation. Trenching is helpful to prevent soil salinization and prevent the occurrence of root diseases caused by flooding. Furrow openers are usually used for trenching.

[0003] According to their design styles, furrow openers can be divided into different types such as hoe type, boat type, V type and disc type. Despite their diverse structures, they are all installed at the bottom of the frame of self-propelled equipment, and the furrowing operation of the farmland is completed by the movement of the equipment. However, when used on hand-held self-propelled equipment, when the furrow opener is not needed, farmers need to connect the equipment with the furrow opener and drive them home together. When the equipment is driving on a normal road, in order to prevent the furrow opener from contacting the road, the farmer needs to lift the equipment to keep the furrow opener away from the road, otherwise it will damage the road surface and the furrow opener, which increases the difficulty of use for farmers.

[0004] Therefore, it is necessary to provide a kind of agricultural machinery furrow opener to solve the above-mentioned technical problems. Utility Model Content

[0029] A furrow opener for agricultural machinery, comprising:

[0030] A connecting arm 1, an adjusting arm 2 is hinged at the bottom end of the connecting arm 1, a crossbeam 3 is welded at the bottom end of the adjusting arm 2, a symmetrically distributed round-shaped positioning piece 7 is sleeved on the outer wall of the crossbeam 3, a connecting metal plate 8 is fixedly installed at the bottom of the round-shaped positioning piece 7, a furrow opener body 9 is arranged at the bottom end of the connecting metal plate 8, and a symmetrically distributed mounting frame 5 is fixedly installed on the front side of the outer wall of the crossbeam 3;

[0031] A roller 4 is rotatably mounted on the mounting frame 5, a latch body 10 is fixedly mounted on the rear side of the outer wall of the connecting arm 1, an insertion rod 12 is movably inserted into the latch body 10, a handle 11 is fixedly mounted on the outer wall of the insertion rod 12, a positioning cylinder 13 is fixedly mounted on the rear side of the outer wall of the adjusting arm 2, and the positioning cylinder 13 is inserted into the insertion rod 12.

[0032] A circular connector 17 is fixedly installed on the back of the furrow opener body 9, and the connecting metal plate 8 is plugged into the circular connector 17. A plurality of mounting holes 16 are opened on the connecting metal plate 8, and the connecting metal plate 8 is detachably connected through the mounting holes 16, the cooperation with the positioning pins and the circular connector 17.

[0033] In one embodiment, the circular positioning member 7 is threadedly connected to the positioning bolt 6 through a threaded hole opened at its top, and a plurality of threaded grooves matching the positioning bolt 6 are opened on the upper side of the outer wall of the beam 3, and the threaded grooves on the upper side of the outer wall of the beam 3 are threadedly connected to the positioning bolt 6.

[0034] In one of the preferred embodiments, symmetrically distributed handles 14 are fixedly mounted on the rear side of the outer wall of the crossbeam 3 to facilitate adjustment of the equipment.

[0035] In one embodiment, a rubber ring is bonded to the outer wall of the handle 14 to help provide additional grip and comfort, while also providing an anti-slip function to make the operation more stable and safer.

[0036] In one of the preferred embodiments, a positioning hole 15 adapted to the insertion rod 12 is opened on the outer wall of the adjusting arm 2. By plugging the insertion rod 12 into the positioning hole 15, the stability of the position of the adjusting arm 2 and the connecting arm 1 when the adjusting arm 2 and the connecting arm 1 are in a right-angle state is ensured, so that the roller 4 can have a more stable contact with the ground, and the stability of the furrow opener body 9 after the position adjustment is ensured.

[0037] The working principle of the utility model is as follows: the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When the furrow opener is in use, it is installed at the bottom of the equipment frame through the connecting arm 1. When the equipment is driven in an area other than a farmland, the farmer directly holds the handle 11 and pulls the insertion rod 12 through the handle 11 to move upward on the latch body 10. As the insertion rod 12 moves, the insertion rod 12 will be separated from the inside of the positioning cylinder 13. After the connection arm 1 and the adjustment arm 2 lose the limit between the insertion rod 12 and the positioning cylinder 13, the adjustment arm 2 at the bottom of the connection arm 1 can be rotated. The farmer directly holds the two handles 14 and drives the crossbeam 3 to flip upward through the handles 14. The movement of the crossbeam 3 drives the mounting frame 5 and the roller 4 to move. The hand-held self-propelled equipment can be moved and driven to move, and the connecting metal plate 8 and the furrow opener body 9 can be moved, so that the furrow opener body 9 can be turned up and away from the ground, and the roller 4 can be turned down and contacted with the ground. At this time, relying on the contact between the roller 4 and the ground, farmers can control the movement of the hand-held self-propelled equipment very easily. Not only do they not have to worry about whether the furrow opener body 9 will scratch the road surface, but they also improve the stability of the equipment and the convenience and safety of farmers' use. When the equipment enters the farmland, the above steps are performed in reverse to complete the position adjustment of the roller 4 and the furrow opener body 9, so that the furrow opener body 9 can contact the ground of the farmland. Then, under the connection between the insertion rod 12 and the positioning cylinder 13, it can be ensured that the connecting arm 1 and the adjustment arm 2 will not rotate, so that the furrow opener body 9 can stably perform furrowing operations on the farmland.

[0038] When the device is in use, multiple furrow opener bodies 9 can be installed on the outer wall of the beam 3. Since the circular positioning member 7 is fixed to the outer wall of the beam 3 by the positioning bolt 6, the spacing of the furrow opener bodies 9 installed on the beam 3 can be adjusted, so that the furrow opener can be flexibly assembled when used in conjunction with other equipment to achieve simultaneous operation of multiple furrows and meet the construction requirements of different furrow spacings, so that farmers can better adapt to various usage scenarios.

[0039] During use, the installation height of the trench opener body 9 can be adjusted by different installation positions of the circular connecting piece 17 on the connecting metal plate 8 to achieve different trenching depths, thereby improving the flexibility of the trench opener body 9 during use and enabling it to better adapt to different trenching requirements.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
