Description

Technical Field

[0001] The utility model relates to the technical field of wheat rollers, in particular to an adjustable roller for wheat planting. Background Art

[0002] Currently, subsoilers and rotary tillers are widely used for soil cultivation. However, these operations loosen the soil. After sowing, insufficient soil compaction disrupts capillary pores, resulting in excessively loose soil around the seeds and loss of moisture. This makes it difficult for the seeds to absorb water, leading to dry germination and seedling failure. This necessitates effective soil compaction after sowing. This increases the density of the soil around the seedbed, ensuring close contact between the seeds and the soil, and creating an environment with the ideal soil density for germination, emergence, and growth. Tillers are primarily used for post-sowing wheat to break up clods, compact the tillage layer, and level the land. The resulting soil forms a U-shaped wave, with looser soil at the crests and denser soil at the troughs. This combination of looseness and firmness provides excellent moisture conservation, ensuring uniform, full, and strong seedlings, ensuring safe wintering, increased yields, and reduced lodging.

[0003] The existing wheat roller is generally installed directly on the seed drill when in use, and its structure itself is relatively simple. It only has a pressing roller rolling on the ground to press the soil after sowing wheat. When in use, this method only presses down and compacts the soil, and the actual pressing effect is poor. In addition, the existing wheat roller is not convenient for adjusting the pressing force. The fluffiness and humidity of different soils are different, and the pressing force often needs to be adjusted at this time. Although there are some rollers with adjustable pressing force on the market, their pressure regulating devices are mostly arranged on both sides of the roller. On the one hand, the adjustment process is more troublesome and laborious. On the other hand, the pressures adjusted by multiple regulating devices are difficult to unify. Therefore, there is an urgent need for an adjustable roller for wheat planting to solve the above-mentioned shortcomings. Utility Model Content

The inner side wall of the pressing roller 4 is rotatably connected to the knocking hammer 11 through a hinge, and the outer surface of the pressing roller 4 is fixedly connected to the anti-slip protrusion 23, and there are several anti-slip protrusions 23 and they are evenly distributed in a circular array.

[0030] In order to improve the suppression effect, Figures 1 to 8As shown, the present application adopts the following structure, through the setting of the connecting rod 2, the pressing roller 4, the inner gear ring 6, the first gear 7, the central shaft 8, the second gear 9, the eccentric protrusion 10 and the knocking hammer 11, in actual use, one end of the first connecting rod 1 of the device and one end of the second connecting rod 13 are respectively rotatably connected to the seeder, when sowing, the seeder descends, and at this time the outer surface of the pressing roller 4 first contacts the ground, and when moving, the pressing roller 4 rotates along the ground, and when rotating, the pressing roller 4 rotates on the outer surface of the connecting rod 2 through the bearing 3, and drives the inner inner gear ring 6 to rotate, and through the transmission action of the inner gear ring 6, the first gear 7 and the second gear 9, it can drive the central shaft 8 to rotate in the opposite direction. At this time, the eccentric protrusion 10 on the outer surface of the central shaft 8 can swing the knocking hammer 11, and release the knocking hammer 11 when it reaches the highest point of the eccentric protrusion 10, and the knocking hammer 11 is released along The eccentric protrusions 10 are freely fallen at their hinges and strike the outer surface of the next eccentric protrusion 10 of the eccentric protrusion 10 or the inner wall of the pressing roller 4, thereby driving the pressing roller 4 to vibrate, causing it to produce a vibrating effect, and the installation of the eccentric protrusions 10 does not need to be symmetrical, so that the center of gravity between the central shaft 8 and the multiple eccentric protrusions 10 deviates from the center line of the central shaft 8. When the central shaft 8 and the eccentric protrusions 10 rotate, a vibration effect can also be generated, further improving the pressing effect of the pressing roller 4, that is, the adjustable roller for wheat planting has the effect of facilitating the improvement of the pressing effect. Through the coordinated arrangement of the connecting rod 2, the pressing roller 4, the inner gear ring 6, the first gear 7, the central shaft 8, the second gear 9, the eccentric protrusions 10 and the knocking hammer 11, the seeder generates vibration while dragging the device to roll, thereby achieving the purpose of facilitating the improvement of the pressing effect.

[0031] Example 2

[0032] The utility model provides a technical solution: the outer surface of the connecting rod 2 is rotatably connected to the sleeve 12, the outer surface of the sleeve 12 is threadedly connected to the knob 14, the outer surface of the second connecting rod 13 is provided with a limiting groove 15, one end of the knob 14 abuts against the inner bottom wall of the limiting groove 15, one end of the sleeve 12 is plugged with the second connecting rod 13, the outer surface of the sleeve 12 is fixedly connected to the first cross bar 16, the inner side wall of the second connecting rod 13 is provided with a sliding groove 17, the inner side wall of the sliding groove 17 is slidably connected to the second cross bar 18 through a slider, one end of the second connecting rod 13 The outer surface of the third cross bar 19 is fixedly connected to the outer surface of the third cross bar 19, and the outer surface of the third cross bar 19 is fixedly connected to the spring 20. Several springs 20 are provided and are evenly distributed in a rectangular array. One end of the spring 20 is fixedly connected to the outer surface of the first cross bar 16, and the inner side wall of the third cross bar 19 is rotatably connected to the adjusting screw 21. The outer surface of one end of the adjusting screw 21 is transmission-connected to the inner side wall of the second cross bar 18. There are two sleeves 12 and the second connecting rod 13, and they are symmetrically arranged. The inner side wall of the adjusting screw 21 is inserted with an adjusting handle 22.

[0033] In order to facilitate the adjustment of the pressure, as shown in the attached Figures 1 to 8 As shown, the present application adopts the following structure. Through the arrangement of the second connecting rod 13, the knob 14, the first cross bar 16, the second cross bar 18, the third cross bar 19, the spring 20 and the adjusting screw 21, the adjustable pressure device for wheat planting has the effect of facilitating the adjustment of the pressure. In actual use, after one end of the second connecting rod 13 and one end of the first connecting rod 1 are respectively installed on the seed drill, the pressure can be adjusted according to different soils and needs. When adjusting, it is only necessary to pull out one end of the adjusting handle 22, hold the adjusting handle 22 and rotate the adjusting screw 21. At this time, the outer surface of the adjusting screw 21 is transmitted to the inner wall of the second cross bar 18, driving the second cross bar 18 to slide inside the slide groove 17 in the direction away from the third cross bar 19, and squeezing the spring 20. The spring 20 forces the other end of the spring 20 to squeeze the outer surface of the first cross bar 16, thereby causing the second connecting rod 13 to extend from the inside of the sleeve 12. When sowing and pressing, since the first connecting rod 1 and the pressing roller 4 have the same descending height, and the angle between the sleeve 12 and the first connecting rod 1 is usually unchanged, when the elastic force of the spring 20 increases, the thrust exerted on the pressing roller 4 becomes larger, thereby achieving the effect of adjusting the pressing force of the pressing roller 4 to increase. Conversely, by adjusting the handle 22 and rotating the adjusting screw 21 in the opposite direction, so that the second cross bar 18 approaches the third cross bar 19, the elastic force of the spring 20 becomes smaller, and the pressing force of the pressing roller 4 becomes smaller. That is, through the coordinated arrangement of the second connecting rod 13, the knob 14, the first cross bar 16, the second cross bar 18, the third cross bar 19, the spring 20 and the adjusting screw 21, during use, the squeezing force of the second cross bar 18 and the first cross bar 16 on the spring 20 can be adjusted by rotating the adjusting screw 21, thereby achieving the effect of adjusting the pressing force of the pressing roller 4 during sowing, thereby achieving the purpose of facilitating the adjustment of the pressing force.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
