[0036] refer to Figure 1-Figure 5 The present application provides a trenching device 10, comprising:

[0037] A mounting frame 20 connected to the traction device;

[0038] A plurality of trench openers 30 are respectively connected to the mounting frame 20;

[0039] The limiting device 40 is connected to the furrow opener 30, and the limiting device 40 is used to drive the furrow opener 30 to move up and down so that the depth of the furrow opener 30 during furrowing remains constant.

[0040] When the equipment is trenching, the mounting frame 20 is mounted on the traction device, and the traction device drives the trench opener 30 to trench. When trenching, the limit device 40 drives the trench opener 30 to move up and down, so that the depth of the trench opener 30 during trenching is kept constant, and thus the depth of trenching of each trench opener 30 is the same. The trenching device 10 of multiple ridges is not a whole, so that the trenching depth of each ridge will not be different due to the terrain of each ridge.

[0041] In some embodiments, the limiting device 40 can be a telescopic motor. By setting a laser ranging sensor to measure the ground height in real time and feed back to the telescopic motor, the telescopic motor drives the trench opener 30 to move up and down to ensure the trenching depth.

[0042] The limiting device 40 includes a rolling device 41 connected to the front end of the furrow opener 30 . The height of the rolling device 41 is higher than the height of the furrow opener 30 . The furrow opener 30 is floatingly connected to the mounting frame 20 .

[0043] Before the equipment digs trenches, the height difference between the rolling device 41 and the trench opener 30 is adjusted. The adjusted height difference is the trenching depth. When digging trenches, the rolling device 41 contacts the ground, and the traction device pulls the trench opener 30 and the rolling device 41 to move. The trench opener 30 digs trenches on the ground, and the rolling device 41 rolls on the ground, and at the same time drives the trench opener 30 to move up and down following the ups and downs of the ground. In short, the distance between the two remains unchanged, so the trenching depth does not change when the ground is ups and downs, that is, the stable trenching action is completed.

[0044] In some embodiments, a multi-link 502 floating mechanism 50 is further included, one end of the multi-link 502 floating mechanism 50 is connected to the mounting frame 20, and the other end is connected to the furrow opener 30. The end of the multi-link 502 floating mechanism 50 connected to the furrow opener 30 can move up and down relative to the other end. By setting the multi-link 502 floating mechanism 50, a floating connection is achieved between the furrow opener 30 and the mounting frame 20, and the furrow opener 30 can achieve the effect of moving up and down with the undulations of the ground through the setting of the rolling device 41.

[0045] The multi-link 502 floating mechanism 50 includes a fixed end plate 501 , a plurality of links 502 , and a movable end plate 503 . One end of the plurality of links 502 is hinged to the fixed end plate 501 , and the other end thereof is hinged to the movable end plate 503 .

[0046] The movable end plate 503 can move up and down relative to the fixed end plate 501 through the connecting rod 502.

[0047] The connecting rods 502 include four connecting rods 502 , which are respectively disposed at the upper and lower ends of the fixed end plate 501 and the movable end plate 503 .

[0048] The multi-link 502 floating mechanism 50 includes tension springs 504 , which are respectively arranged on both sides of the movable end plate 503 . One end of the tension spring 504 is connected to the upper connecting rod 502 , and the other end is connected to the lower connecting rod 502 .

[0049] Under the action of gravity and the tension of the added tension spring 504, the movable end plate 503 realizes the downward pressing action of the furrow opener 30 to ensure the stability of furrowing.

[0050] The multi-link 502 floating mechanism 50 includes two inner brackets 505, a movable bearing 506 and a fastener 507. The two inner brackets 505 are arranged in parallel, one end of the inner bracket 505 is connected to the movable end plate 503, and the other end is connected to the fixed end plate 501. Both ends of the inner bracket 505 have protruding cylindrical parts. The two sides of the fixed end plate 501 are respectively penetrated by the cylindrical parts at both ends of the inner bracket 505, and the two sides of the movable end plate 503 are respectively penetrated by the cylindrical parts at both ends of the inner bracket 505. The movable bearing 506 is provided on the cylindrical part, the end of the connecting rod 502 is connected to the movable bearing 506, and the fastener 507 is connected to the cylindrical part outside the movable bearing 506.

[0051] The inner bracket 505 is provided so that the movable end plate 503 will not shake in a direction perpendicular to the furrowing direction, thereby ensuring the stability of the furrow opener 30.

[0052] The fixed end plate 501 is connected to the mounting frame 20 via a square sleeve.

[0053] The rolling device 41 is connected to one end of the multi-link 502 floating mechanism 50 connected to the furrow opener 30, and the rolling device 41 includes a rolling bracket 411, a wheel frame 412, a rolling bearing and a rolling wheel 413. The rolling wheel 413 is rotatably connected to a rolling shaft on the wheel frame 412, and the rolling shaft extends to both sides of the wheel frame 412. The rolling bearings are connected to both ends of the rolling shaft, and the rolling bracket 411 is connected to the rolling sleeve.

[0054] The rolling wheel 413 is placed on the ground and can roll on the ground under the traction or drive of the traction device, while also limiting the ditching speed of the ditch opener 30.

[0055] In some embodiments, the trench opener 30 includes a trenching end 301, a material blanking tube 302 and a slotting member 303. The front end of the trenching end 301 is a triangular structure. The material blanking tube 302 is connected to the trenching end 301 to guide the material blanking 302 in the material box 60. The slotting member 303 is connected to the bottom of the trenching end 301 and is lower than the trenching end 301, and corresponds to the position of the material blanking tube 302.

[0056] The seeds in the material box 60 enter the furrowing end 301 through the material dropping tube 302. The position of the groove member 303 is lower than the furrowing end 301. Therefore, the groove member 303 can open another sowing furrow in the furrow. After the seeds enter the material dropping tube 302, they fall into the sowing furrow.

[0057] A furrowing device 10 includes a mounting frame 20, four or more furrow openers 30, and a limiting device 40. The furrow openers 30 are floatingly connected to the mounting frame 20 via a multi-link 502 floating mechanism 50. The limiting device 40 is connected to the multi-link 502 floating mechanism 50. The limiting device 40 is used to control the distance between the furrow opener 30 and the ground to be reclaimed to remain constant.
