Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting press wheel technology, and specifically relates to an agricultural planting press wheel and its width adjustment structure. Background Technology

[0002] Agricultural compaction rollers are specialized agricultural machinery used to compact soil after sowing, improving the crop growing environment and increasing crop yield. Typically mounted behind seeders or tillers, these rollers are designed to compact the soil by applying vertical pressure, ensuring good seed-soil contact and promoting water absorption and germination. However, agricultural compaction rollers without adjustable width have significant drawbacks. Their fixed design limits their adaptability to different soil conditions and crop requirements. First, the fixed width prevents flexible adjustment based on soil type and moisture, leading to over-compaction in some cases. Over-compaction damages soil structure, reduces porosity, and consequently affects aeration and permeability, further hindering root growth and development, limiting water and nutrient absorption, and ultimately reducing crop yield. Therefore, we aim to design an agricultural compaction roller with an adjustable width to address this problem. Utility Model Content

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: an agricultural planting pressing wheel and a width adjustment structure, including: a crossbeam 1, with connecting rods 2 fixedly connected to both the left and right ends of the crossbeam 1, and an adjustment mechanism 3 for adjusting the installation spacing of the pressing wheel 42 provided on the connecting rods 2, and a splicing mechanism 4 for widening the pressing wheel 42 provided on the adjustment mechanism 3.

[0024] The splicing mechanism 4 includes a connecting shaft 41, a pressure roller 42 fixedly sleeved on the outer side of the connecting shaft 41, and a widening roller 43 movably sleeved on the outer side of the connecting shaft 41. A synchronizing rod 44 is fixedly connected to the side of the widening roller 43 near the pressure roller 42. The synchronizing rod 44 is slidably sleeved inside the pressure roller 42. The pressure roller 42 is in contact with the widening roller 43. By setting the splicing mechanism 4, the width of the pressure roller 42 can be adjusted by increasing or decreasing the width of the widening roller 43.

[0025] The splicing mechanism 4 also includes a sliding sleeve 45, which is slidably sleeved on the outside of the connecting shaft 41. A connecting plate 46 is fixedly connected to the right end of the sliding sleeve 45, and an insertion rod 47 is fixedly connected to the connecting plate 46. The insertion rod 47 is slidably sleeved inside the widened wheel 43.

[0026] The left end of the sliding sleeve 45 is threaded with a limiting rod 48 to prevent the sliding sleeve 45 from rotating.

[0027] The connecting shaft 41 is provided with a groove 49 for sliding the limiting rod 48.

[0028] The adjustment mechanism 3 includes a support frame 31, which is fixedly connected to the connecting rod 2. A drive shaft 32 passes through the inside of the support frame 31 via a bearing. A main bevel gear 33 is fixedly connected to the lower end of the drive shaft 32. By setting the adjustment mechanism 3, the distance between the two connecting plates 38 can be adjusted to increase or decrease the width of the wheel 43.

[0029] The connecting rod 2 is internally connected to a threaded rod 34 via a bearing. A secondary bevel gear 35 is fixedly sleeved on the outer side of the threaded rod 34. The secondary bevel gear 35 meshes with the main bevel gear 33. By setting the secondary bevel gear 35 to mesh with the main bevel gear 33, the threaded rod 34 is driven to rotate.

[0030] The threaded rod 34 is a bidirectional threaded rod 34 used to drive the connecting arms 36 at both ends of the threaded rod 34 to move in opposite directions or in opposite directions.

[0031] A connecting arm 36 is screwed onto the outer side of the threaded rod 34. A fixing sleeve 37 is fixedly sleeved on the outer side of the connecting arm 36.

[0032] Please see Figure 1 , Figure 2 , Figure 4 As the first embodiment of this utility model: when it is necessary to adjust the pressure roller 42, the sliding sleeve 45 is first displaced by operating the adjustment mechanism 3. During the displacement, the sliding sleeve 45 drives the connecting plate 46 and the insertion rod 47 to move. When the sliding sleeve 45 is displaced from the connecting shaft 41, the widening wheel 43 is moved away from the pressure roller 42. When the widening wheel 43 is displaced from the connecting shaft 41, the width of the pressure roller 42 can be adjusted by reducing the width of the widening wheel 43. Finally, the sliding sleeve 45 is installed back onto the connecting shaft 41, and the adjustment mechanism 3 is operated again to drive the connecting plate 46 and the insertion rod 47 to move, so that the insertion rod 47 is inserted into the interior of the pressure roller 42.

During the rotation of the drive shaft 32, it drives the main bevel gear 33 fixedly connected to it to rotate. During the rotation of the main bevel gear 33, it drives the secondary bevel gear 35 meshing with it to rotate. At the same time, the secondary bevel gear 35 drives the threaded rod 34 to rotate. The threaded rod 34 then generates threaded movement with the inside of the connecting arm 36, causing the connecting arm 36 to drive the connecting plate 38 to move. Further, the connecting plate 38 drives the sliding sleeve 45 to move, causing the sliding sleeve 45 to drive the connecting plate 46 and the insert rod 47 to disengage from the connecting shaft 41, so as to facilitate the addition or removal of the widening wheel 43 to realize the width adjustment of the pressure wheel 42.
