Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trenching structures, and specifically relates to a trencher with high trenching strength. Background Technology
[0002] The furrowing component is a crucial part of seeding and fertilizing machinery. Its performance directly affects the operation of the seeder and fertilizer applicator, influencing the accuracy of seed and fertilizer distribution within rows and at depth, seeding and germination rates, and the overall balance, stability, and power consumption of the machine. However, soil hardness varies. For relatively loose soil, the furrow opener can effectively open and turn the soil using its blades. But for harder soil, using the same blades can lead to faster wear and tear, and the furrowing and loosening effects are less than ideal. Summary of the Invention

A plurality of first tillage blades 320 are provided on the first support shaft 300, a first ditching plow 200 is provided at the lower end of the first connecting frame 110, a first connecting plate 210 at both ends of the first ditching plow 200, a plurality of first through holes 211 on the first connecting plate 210, and a plurality of third mounting holes 111 at both ends of the first connecting frame 110, with each of the first through holes 211 corresponding to one of the third mounting holes 111.
[0022] Furthermore, the rear end of the first trenching plow 200 is provided with a first soil-breaking wall 220, the first soil-breaking wall 220 is connected to the lower end of the first connecting plate 210, the lower end of the first soil-breaking wall 220 is provided with a first plow tip 221, the first plow tip 221 is flat, and the upper end of the first soil-breaking wall 220 is provided with a first soil-breaking cone 222.
[0023] Furthermore, the first support shaft 300 is provided with a plurality of first connecting frames 310, the first tillage blade 320 corresponds one-to-one with the first connecting frame 310, the first tillage blade 320 is provided with a plurality of second through holes, and the first connecting frame 310 is provided with a plurality of third through holes, the third through holes corresponding one-to-one with the second through holes.
[0024] Furthermore, the front end of the first furrowing plow 200 is provided with an adjustment mechanism, the adjustment mechanism including a first mounting frame 230, the two ends of the first mounting frame 230 are provided with first soil spreading plates 240, the rear end of the first soil spreading plates 240 is hinged to the rear end of the first mounting frame, the middle part of the first mounting frame is provided with a first moving block 250, the two ends of the first moving block 250 are hinged with first connecting rods 260, the end of the first connecting rods 260 is hinged to the front end of the first soil spreading plates 240, the first mounting frame 230 is provided with a first limiting strip 231, the two ends of the first moving block 250 are provided with first limiting grooves, and the first limiting strip 231 corresponds one-to-one with the first limiting groove.
[0025] Furthermore, the first mounting frame 230 has several first slots at both ends, and the first moving block 250 has first locking posts 251 hinged at both ends, with the first locking posts 251 matching the first slots.
[0026] Working principle: The first support shaft 300 is driven by drive mechanisms at both ends of the first support frame 100. Rotation of the first support shaft 300 drives the first tillage blade 320 to loosen the soil. The first tillage blade 320 loosens loose soil. When encountering hard soil, as the first support frame 100 moves, the first plow tip 221 inserts into the soil. Due to its flattened design, the first plow tip 221 can insert into the soil more easily with less resistance. The first soil-breaking cone 222 then pushes the soil apart, achieving the effect of loosening the soil. Furthermore, compared to the first tillage blade 320, the first furrowing plow 200 is made of steel or cast iron, with high structural strength and a thick overall structure, capable of withstanding the friction and compression of hard soil, thus preventing damage to the first tillage blade 320 when furrowing in hard soil.
[0027] During trenching, the position of the first moving block 250 is adjusted so that the first soil-expanding plate 240 is flipped and unfolded, allowing it to expand at a certain angle. This expands the width of the trench during loosening of the soil. After moving the first moving block 250 to a suitable position, the first locking post 251 is rotated into the first locking slot, causing it to lock the first moving block 250, thereby maintaining the position of the first soil-expanding plate 240.
[0028] It is worth mentioning that the technical features such as the setting of the first card slot involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.
[0029] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
