[0022] In the furrowing plow device of the present invention, the support beam 1 is connected to the rotary tiller through the soil entry angle adjustment structure 3, which can not only adjust the inclination angle of the plow 2 to adapt to different farmland soil and arable land requirements, but also the rotary tiller drives the plow 2 to work in furrowing. The support rod 5 adjusts the distance between the plow 2 and the support beam 1 through the height adjustment structure 6, thereby adjusting the depth of the furrow, which is conducive to taking into account both drainage and the development of plant roots and promoting plant growth. The left extended plow wall 23 and the right extended plow wall 24 change their angles through the width adjustment structure 4, change the total width of the plow wall 22, adjust the width of the furrowing, meet production needs, save time for replacing the furrowing plow, improve production efficiency, and reduce the cost of purchasing plows. The left plow wall 221 and the right plow wall 222 are symmetrically arranged on the left and right sides of the support rod 5, and the plow wall 22 just starts to push the floating soil to both sides from the middle position of the furrowed furrow, thereby ensuring the stability of the plow 2 operation.

[0023] See also Figure 2Further, the width adjustment structure 4 includes a support plate 41, a first connecting plate 42, a second connecting plate 43 and a hanging ear 44; a hanging ear 44 is respectively provided on the opposite side of the left extended plowboard 23 and the right extended plowboard 24. The support plate 41 is fixedly mounted on the support rod 5, and the support plate 41 is evenly spaced with a group of first through holes 411 along its length direction, the first connecting plate 42 is evenly spaced with a group of second through holes 421 along its length direction, and the second connecting plate 43 is evenly spaced with a group of third through holes 431 along its length direction, and one end of the first connecting plate 42 and the second connecting plate 43 are respectively connected to the corresponding hanging ear 44.

Specifically, according to the required groove width and groove shape, for example, the groove is symmetrically arranged as a whole, a second through hole 421 is selected in the first connecting plate 42, and a corresponding third through hole 431 is selected in the second connecting plate 43, and the first connecting plate 42 and the second connecting plate 43 are superimposed and fixed in the support plate 41 by bolts and flange nuts. When the left extended plowboard 23 and the right extended plowboard 24 are at different angles with the plowboard 22, the first connecting plate 42 and the second connecting plate 43 are respectively fixed at different positions of the first through hole 411. The width adjustment structure 4 can obtain grooves of different widths and shapes to meet the needs of drainage, water storage and plant root development.

[0024] See also Figure 2 Furthermore, a fourth through hole 422 is provided at one end of the first connecting plate 42 and the second connecting plate 43 near the hanging ear 44, and the hanging ear 44 is sleeved in the fourth through hole 422. With this structure, the hanging ear 44 and the first connecting plate 42 or the second connecting plate 43 can move relative to each other by utilizing the gap between the hanging ear 44 and the fourth through hole 422, so as to avoid direct rigidity collision with soil when the left extended plowboard 23 and the right extended plowboard 24 are subjected to resistance during the furrowing process, thereby reducing damage to the left extended plowboard 23 and the right extended plowboard 24.

[0025] See also Figure 2 Furthermore, the plow also includes a reinforcing plate 25, which is horizontally fixedly connected to the support rod 5, and the two ends of the reinforcing plate 25 are respectively connected to the opposite sides of the left plow wall 221 and the right plow wall 222. This makes the connection between the left plow wall 221 and the right plow wall 222 more firm and reliable, and can effectively prevent the plow wall 22 from deforming during operation. Preferably, a plurality of reinforcing plates 25 can be provided, and the support plate 41 is "L"-shaped, and the end surface of the support plate 41 away from the first through hole 411 is fixedly connected to one group of reinforcing plates 25, thereby optimizing the structure of the plow 2,

[0026] See also Figure 3Furthermore, the working surface of the plowboard 22 is arc-shaped. With the arc-shaped structure, the plowboard 22 can better break and turn the soil, and can better adapt to the terrain changes. The arc-shaped structure can effectively reduce the soil adhesion and clogging phenomenon, so it is suitable for sticky soil and soil conditions with high humidity.

[0027] See also Figure 2 and Figure 3 , further, the plowshare 21 is configured as a triangular sheet structure, the lower ends of the left plowwall 221 and the right plowwall 222 form an acute angle between them and are installed on the plowshare 21, and the upper ends of the left plowwall 221 and the right plowwall 222 form a right angle between them and are respectively connected to the support rod 5. Preferably, the plowshare 21 is configured as an isosceles triangular sheet structure, which has the advantages of easy entry into the soil and low trenching resistance. The center of the support rod 5 coincides with the inner center of the plowshare 21, and the upper ends of the left plowwall 221 and the right plowwall 222 are respectively connected to the support rod 5, which enhances the strength of the plowwall 22 and reduces the deformation of the plowwall 22 during the working process, and the end of the plowshare 21 entering the soil is an acute angle, which reduces the resistance to entering the soil.

[0028] See also Figure 1 and Figure 2 Furthermore, the soil entry angle adjustment structure 3 includes a rotating plate, one end of which is rotatably mounted on the rotary tiller, and the other end is fixedly connected to the support beam 1. Specifically, the rotating plate is provided with a set of fifth through holes 31, and the rotating plate is fixedly installed in the rotary tiller by passing the fifth through holes 31 with hexagonal bolts, and the rotating plate is provided with a through slot 32, and the support beam 1 is fixedly installed in the through slot 32 by welding. When the plow angle needs to be adjusted, the hexagonal bolts are loosened, and the rotating plate can be rotated to drive the support beam 1 to rotate, so that the plow 2 forms a desired angle with the ground.

[0029] See also Figure 2 , further, the height adjustment structure 6 includes a fixed block 61, two groups of U-shaped clamps 62 and a nut 63; the U-shaped clamp 62 is inserted into the support beam 1 and moves along the support beam 1, the open end of the U-shaped clamp 62 is provided with a thread, the open end of the U-shaped clamp 62 passes through the fixed block 61 and is threadedly connected with the nut 63, and the support rod 5 is inserted between the fixed block 61 and the two groups of U-shaped clamps 62 and fastened with the nut 63. Specifically, the fixed block 61 is provided with a sixth through hole that matches the open end of the U-shaped clamp 62, the open end of the U-shaped clamp 62 passes through the sixth through hole, and the nut 63 is installed on the thread. If adjustment is required, loosen the nut 63, move the U-shaped clamp 62 along the length direction of the support beam 1, drive the fixed block 61 to move, change the distance between the two groups of plows 2, and thus change the distance between the furrows; loosen the nut 63, the support rod 5 can move up and down between the fixed block 61 and the support beam 1, adjust the height of the plow 2, and change the height of the furrow. Tighten nut 63 when the height and distance are appropriate.

[0030] In the furrowing plow device of the present invention, the support beam 1 adjusts the furrowing angle, the distance between furrows, the depth and width of the furrows through the furrowing angle adjustment structure 3, the height adjustment structure 6 and the width adjustment structure 4, so as to meet the production needs, save the time of replacing the furrowing plow, improve the production efficiency and reduce the cost of purchasing the plow. The structural design of the plowshare 21 and the plow wall 22 reduces the resistance of furrowing, and the gap between the hanging ear 44 and the fourth through hole 422 is used to reduce the damage of the left extended plow wall 23 and the right extended plow wall 24, thereby extending the life of the plow 2.
