[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] The present application embodiment discloses a furrow opener. Figure 1-5 A furrow opener comprises a bottom plate 1, a seed box 2 is fixedly installed on the top of the bottom plate 1, two groups of furrowing blocks 3 are arranged on the bottom plate 1, two groups of supporting grooves 4 are symmetrically opened on the bottom plate 1, a lifting plate 5 is arranged at one end of the bottom plate 1, a guide groove 6 is opened at the bottom of the lifting plate 5, the furrowing blocks 3 are connected to the lifting plate 5 through the guide groove 6, four groups of supporting legs 7 are fixedly installed at the bottom of the bottom plate 1, and universal wheels 8 are movably installed at the bottom of the supporting legs 7 through movable shafts;

[0024] By adopting the above technical solution, the supporting legs 7 cooperate with the universal wheels 8 to facilitate the movement of the entire device and thus change to different working positions.

[0025] Reference Figure 2-3 , two groups of protrusions 9 cooperating with the support grooves 4 are fixedly installed on the lifting plate 5, a motor 10 is fixedly installed on the bottom plate 1, and a threaded rod 11 cooperating with the protrusions 9 is installed at the output end of the motor 10, a guide block 12 cooperating with the guide groove 6 is fixedly installed on the top of the ditching block 3, a motor 2 13 is fixedly installed on one side of the bottom plate 1, and a positive and negative screw rod 14 cooperating with the guide block 12 is installed at the output end of the motor 2 13;

[0026] By adopting the above technical solution, the motor 10 is started, and the motor 10 drives the threaded rod 11 to rotate. Through the guiding effect of the support groove 4 and the protrusion 9, the lifting plate 5 can be driven to rise and fall. The lifting plate 5 drives the two groups of ditching blocks 3 to rise and fall through the action of the guide groove 6 and the guide block 12, thereby adjusting the ditching depth of the two groups of ditching blocks 3. The motor 2 13 is started, and the motor 2 13 drives the forward and reverse screw rods 14 to rotate. Through the guiding effect of the guide groove 6, the forward and reverse screw rods 14 drive the two groups of guide blocks 12 to move in opposite directions, thereby adjusting the distance between the two groups of ditching blocks 3, so that they can perform ditching work with different spacings, which can not only adjust the ditching depth, but also adjust the spacing between the two grooves.

[0027] Reference Figure 4-5 A strip hole is provided through the bottom plate 1, and slide grooves 15 are symmetrically provided on both sides of the strip hole. Two groups of hollow blocks 16 are arranged in the strip hole, and pulleys 17 cooperating with the slide grooves 15 are fixedly installed on both sides of the hollow block 16.

Connecting rods 20 are fixedly installed on the hollow blocks 16, and driving blocks 21 are fixedly installed on the connecting rods 20. Driving grooves 22 cooperating with the driving blocks 21 are provided on the ditching blocks 3;

[0028] By adopting the above technical solution, through the action of the driving block 21 cooperating with the driving groove 22, when the distance between the two groups of trenching blocks 3 is adjusted, the hollow block 16 will be driven to move through the connecting rod 20, so that it can sprinkle seeds on the trenches of the trenching blocks 3. At the same time, when the height of the trenching blocks 3 is adjusted, it will not affect the hollow block 16. Through the action of the slide groove 15 cooperating with the pulley 17, the friction between the hollow block 16 and the bottom plate 1 can be reduced, so that the movement of the hollow block 16 is smoother.

[0029] The implementation principle of a furrowing device in an embodiment of the present application is as follows: start motor 10, motor 10 drives the threaded rod 11 to rotate, and through the guiding effect of the support groove 4 and the protrusion 9, the lifting plate 5 can be driven to lift and lower, and the lifting plate 5 drives the two groups of furrowing blocks 3 to lift and lower through the action of the guide groove 6 and the guide block 12, thereby the furrowing depth of the two groups of furrowing blocks 3 can be adjusted, start motor 2 13, motor 2 13 drives the forward and reverse screw rods 14 to rotate, and through the guiding effect of the guide groove 6, the forward and reverse screw rods 14 drive the two groups of guide blocks 12 to move in opposite directions, thereby the distance between the two groups of furrowing blocks 3 can be adjusted, so that furrowing work with different spacings can be performed, not only the furrowing depth can be adjusted, but also the spacing between the two furrows can be adjusted, and the seed box 2 can sow in the furrows through the action of the hose 18, the hollow block 16 and the discharge port 19.
