Figure 1 The layout is described in detail, such as the positional relationship of front, back, top, bottom, left, right, etc., which is based on the attached manual. Figure 1 It is determined by the layout direction.
[0026] The present invention is further described below in conjunction with the embodiments and drawings:
[0027] Embodiment 1: As shown in the attached Figure 1 , 2As shown in Figures 3, 4 and 6, the elastic connecting device of the furrow opener includes a beam seat 1, a connecting shaft 2, a limit plate 3, an adjusting component, a mounting seat and a fertilizer pipe seat 4. The connecting shaft 2 is installed on the inner side of the lower part of the beam seat 1, and the limit plate 3 is fixedly installed on the inner side of the upper part of the beam seat 1 corresponding to the upper right position of the connecting shaft 2. A connecting hole that passes through the left and right sides is provided on the right side of the limit plate 3. A first connecting arm 5 is rotatably installed on the outer side of the connecting shaft 2. A connecting rod 7 with a right end passing through the connecting hole is hingedly installed on the upper end of the first connecting arm 5. A second connecting arm 6 is fixedly installed on the lower part of the first connecting arm 5, and a mounting seat is fixedly installed on the right side of the second connecting arm 6. A fertilizer pipe seat 4 with a tubular structure is installed in the mounting seat. An adjusting component is installed between the right part of the connecting rod 7 and the right side of the limit plate 3. The adjusting component includes an adjusting nut 15 and an elastic reset member 16. The adjusting nut 15 is screwed on the outer side of the right part of the connecting rod 7, and an elastic reset member 16 is provided between the left end of the adjusting nut 15 and the right side of the limit plate 3.
[0028] According to requirements, the connecting shaft 2 can be an existing well-known technology, such as a connecting pin passed through the lower part of the beam seat 1 and a cotter pin installed at the end of the connecting pin. The elastic reset member 16 is an existing well-known technology, such as a compression spring. A washer is provided between the elastic reset member 16 and the left end of the adjusting nut 15, so that the force area of the right end of the elastic reset member 16 can be increased to prevent the elastic reset member 16 from losing its force on the first connecting arm 5 after falling off. The front and rear sides of the first connecting arm 5 are fixed with spacers mounted on the outside of the connecting shaft 2, and the right side of the limit plate 3 corresponding to the position of the connecting hole is fixed with a positioning sleeve mounted on the outside of the connecting rod 7, so that the compression spring can be fixed to the middle part of the connecting rod 7, and the first connecting arm 5 and the second connecting arm 6 can be arranged as a whole. A fastening screw hole connected inside and outside is provided on the outer side of the upper part of the fat pipe seat 4, and a fastening bolt is threaded in the fastening screw hole.
[0029] When in use, the mounting base is installed together with the existing known furrow opener, and the beam seat 1 is fixedly installed together with the frame. In this way, when the beam seat 1 moves forward with the frame, when the furrow opener encounters large stones or tree roots, the furrow opener rotates and rises to a certain angle, and then resets through the elastic reset member 16 after passing through, so as to avoid damage to working parts. By adjusting the position of the adjusting nut 15 and changing the compression amount of the elastic reset member 16, the passing performance of the furrow opener can be increased, and it can also adapt to different soils.
[0030] The above-mentioned flexible connecting device of the furrow opener can be further optimized and / or improved according to actual needs:
[0031] Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2As shown in Figures 4 and 5, the mounting base includes a first fixing sleeve 8 and a second fixing sleeve 9, the right end of the second connecting arm 6 is fixedly mounted together with the outer side of the left portion of the first fixing sleeve 8, at least one first fixing screw hole which passes through the upper portion of the outer side of the first fixing sleeve 8 is arranged at intervals from front to back, and a first fixing bolt 10 is screwed into each first fixing screw hole, the right side of the rear portion of the first fixing sleeve 8 is fixedly mounted together with the left end of the second fixing sleeve 9, at least one second fixing screw hole which passes through the upper portion of the outer side of the second fixing sleeve 9 is arranged at intervals from left to right, and a second fixing bolt 11 is screwed into each second fixing screw hole, a fixing rod 12 is sleeved in the second fixing sleeve 9, and the right end of the fixing rod 12 is mounted together with the outer side of the lower portion of the fat pipe seat 4.
[0032] According to the requirements, in order to increase the depth of the first fixing screw hole and the second fixing screw hole, nuts can be welded on the outside of the first fixing sleeve 8 and the outside of the second fixing sleeve 9, which makes the processing and manufacturing of the screw holes more convenient. The first fixing sleeve 8 can be used to install the central axis of the existing known furrow opener. The furrow opener can be a single disc furrow opener 19 or a double disc furrow opener. The fertilizer pipe seat 4 can also be fixed integrally with the second fixing sleeve 9 through the fixing rod 12. During use, through such a setting, the position of the furrow opener can be adjusted. Compared with the traditional fixed furrow opener, it has the advantages of less upper and lower space occupation and convenient adjustment and movement.
[0033] Embodiment 3: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in FIGS. 4 and 5 , the front portion of the first fixed sleeve 8 is tilted to the right relative to the rear portion, and the central axis of the second fixed sleeve 9 is perpendicular to the central axis of the first fixed sleeve 8 .
[0034] The inclination angle of the fertilizer pipe seat 4 can be adjusted as needed and fixedly installed with the right end of the fixing rod 12, so that the fertilizer can be spread in the middle of the ditch according to the fertilizer application direction. In this way, the elastic connecting device of the furrow opener equipped with the furrow opener can be symmetrically installed on the main beam, which is convenient for the connection between the fertilizer pipe and the fertilizer pipe seat 4, making the structure more compact.
[0035] Embodiment 4: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown, the lower rear side of the fertilizer pipe seat 4 extends downward to form a fan-shaped baffle 13.
[0036] On the one hand, the resistance of the fertilizer pipe seat 4 in the soil can be reduced when the main beam advances. On the other hand, the fertilizer in the fertilization box falls into the soil layer along the baffle 13 at the lower end of the fertilizer pipe seat 4 to ensure the fertilization depth.
[0037] Embodiment 5: The difference between this embodiment and embodiment 2 is only that the mounting base is different. Figure 7 , 8As shown in Figures 9 and 10, the second connecting arm 6 is in an arc shape with an opening upward, and the mounting seat includes a dividing plate 14. The dividing plate 14 is in a U shape with an opening to the right. The left side of the dividing plate 14 is fixedly installed with the right end of the second connecting arm 6, and the outer side of the lower part of the fertilizer pipe seat 4 is fixedly installed on the inner side of the upper part of the dividing plate 14.
[0038] According to the requirements, the upper side of the second connecting arm 6 may be integrally provided with an existing well-known sliding blade type furrow opener 20, or the lower side of the second connecting arm 6 may be integrally provided with an existing well-known shoe type furrow opener. During use, the sliding blade type furrow opener 20 presses and cuts the soil downward, and while pushing the topsoil to both sides, it squeezes downward to form a fertilizer furrow. The setting of the soil dividing plate 14 can prevent the fertilizer from being spilled to the bottom of the furrow before the soil on both sides falls into it, thereby ensuring the fertilization depth.
[0039] Embodiment 6: As an optimization of the above embodiment, as shown in the attached Figure 7 , 8 As shown in FIGS. 9 and 10 , the width of the soil dividing plate 14 gradually decreases from top to bottom.
[0040] The inclination angle of the fertilizer pipe seat 4 can be adjusted as needed and then fixedly installed with the inner side of the left part of the soil dividing plate 14, so as to facilitate the fertilizer to be spread in the middle of the ditch according to the fertilizer dispensing direction. During use, the upper part of the fertilizer pipe seat 4 is tilted to the right relative to the lower part, which can reduce the falling speed of the fertilizer, and can prevent the granular fertilizer from bouncing out of the ditch after falling into the fertilizer ditch, which is not conducive to subsequent sowing operations. The width of the soil dividing plate 14 gradually decreases from top to bottom, which can prevent the fertilizer from being sprinkled to the bottom of the ditch before the soil on both sides falls into it, thereby ensuring the fertilization depth.
[0041] Embodiment 7: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in FIGS. 3, 7 and 8, a bottom plate 17 is fixedly mounted on the upper side of the beam seat 1, and a plurality of pairs of clamping platforms 18 are fixedly mounted on the upper side of the bottom plate 17 at intervals in the front and rear.
[0042] According to the requirements, a U-shaped connecting bolt 21 with an opening facing downward is installed on the bottom plate 17, and connecting nuts are screwed on the outer sides of both ends of the U-shaped connecting bolt 21. The bottom plate 17 is detachably fixed to the main beam through the U-shaped connecting bolt 21 and the connecting nut. The bottom plate 17 can also be detachably fixed to the main beam through the existing well-known U-shaped clamp or clamp or tile cover. During use, such a setting facilitates the disassembly and assembly between the furrow opener and the main beam. Several pairs of clamping platforms 18 are fixed at intervals on the front and back of the upper side of the bottom plate 17. The distance between each pair of clamping platforms 18 matches the width of the main beam, so that each pair of clamping platforms 18 can limit the main beam, making the clamping beam seat 1 more stable during use.
[0043] The above technical features respectively constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
