Description

Technical Field

[0001] The utility model relates to the field of pressing wheels, in particular to a supporting structure of a pressing wheel of a seed drill. Background Art

[0002] The vegetable seeder has a roller-shaped pressing wheel, which can flatten the soil when the vegetable seeder is moving on the soil surface. When the vegetable seeder is going to the workplace, it sometimes needs to travel a short distance on a hard road surface. There may be hard particles such as stones on the hard road surface. The surface of the pressing wheel will become bumpy after being hit by hard particles, affecting the effect of the pressing wheel flattening the soil. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a support structure for a seed drill pressing wheel, which can support the pressing wheel away from a hard running surface to prevent the pressing wheel from being damaged.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a support structure of a seed drill pressing wheel, including a drum-shaped pressing wheel, on which at least two rolling support plates are installed, and the outer diameter of the rolling support plates is larger than the outer diameter of the pressing wheel, so that the rolling support plates can support the pressing wheel away from the hard driving surface; the rolling support plates are pressed with a plurality of grooves in the thickness direction, and the grooves extend to the edge of the rolling support plates, so that the edge of the rolling support plates forms a tooth-like structure; the plurality of grooves are circumferentially distributed on the rolling support plates, and adjacent grooves on the rolling support plates are respectively located on the two side surfaces of the rolling support plates, and the depth directions of adjacent grooves are opposite, so that the edge of the rolling support plates forms a tooth-like structure alternating left and right; the grooves have an arc-shaped bottom, and arc-shaped teeth are formed after the grooves extend to the edge of the rolling support plates.

[0005] Furthermore, there are two rolling support plates, which are respectively located at two ends of the pressing wheel.

[0006] Furthermore, the outer contour of the rolling support plate is circular, and the rolling support plate is concentrically arranged with the pressing wheel.

[0007] Furthermore, both ends of the suppressing wheel are connected with end shafts, and rolling support plates are fixedly arranged on the end shafts, and the rolling support plates roll synchronously with the suppressing wheel.

[0008] Furthermore, both ends of the suppressing wheel are connected with end shafts, and the rolling support plate is installed on the end shafts through bearings, so that the rolling support plate and the suppressing wheel can rotate independently.

[0009] Furthermore, the seed drill is provided with a driving mechanism for driving the rolling support piece to rotate independently.

[0010] Beneficial effects: The utility model provides a support structure for the pressing wheel of a seeder, and rolling support plates are respectively arranged at both ends of the pressing wheel. The outer diameter of the rolling support plates is larger than the pressing wheel. When the seeder is traveling on a hard road surface, the rolling support plates will support the pressing wheel away from the hard road surface to prevent the pressing wheel from being damaged. When the seeder is traveling on a soft soil surface for sowing, the rolling support plates are thinner and thus will sink into the soil, allowing the pressing wheel to contact the soil surface and flatten the soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 It is a schematic diagram of the overall structure of the pressing wheel of the utility model. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] As attached Figure 1 The support structure of the press wheel of a seed drill comprises a roller-shaped press wheel 1, on which at least two rolling support sheets 2 are mounted, and the outer diameter of the rolling support sheets 2 is larger than the outer diameter of the press wheel 1, so when the seed drill is traveling on a hard road surface, the rolling support sheets 2 can contact the hard road surface before the press wheel 1, so that the rolling support sheets 2 can support the press wheel 1 away from the hard driving surface, avoiding the press wheel 1 from directly contacting the hard driving surface, thereby avoiding damage to the press wheel 1. When the seed drill is traveling on a soft soil surface for sowing, since the rolling support sheets 2 are relatively thin, the rolling support sheets 2 will sink into the soil, so that the press wheel 1 contacts the soil surface.

[0014] The rolling support sheet 2 is provided with a plurality of pressing grooves 3 in the thickness direction, and the pressing grooves 3 extend to the edge of the rolling support sheet 2, so that the edge of the rolling support sheet 2 forms a tooth-like structure. The existence of the tooth-like structure improves the structural strength of the edge of the rolling support sheet 2, and the rolling support sheet 2 is not easy to deform. If the rolling support sheet 2 is a simple thin sheet structure, the rolling support sheet 2 is easy to be skewed and deformed when supporting the weight of the seed drill, resulting in the rolling support sheet 2 being unable to roll normally.

[0015] A plurality of grooves 3 are distributed circumferentially on the rolling support sheet 2, and adjacent grooves 3 on the rolling support sheet 2 are respectively located on the two side surfaces of the rolling support sheet 2, and the depth directions of adjacent grooves 3 are opposite, so that the edge of the rolling support sheet 2 forms a tooth-like structure that alternates left and right. The tooth-like structure that alternates left and right can further improve the structural strength and stability of the rolling support sheet 2.

[0016] The bottom of the pressing groove 3 is arc-shaped, and the structural stability of the arc-shaped groove bottom is higher, which is equivalent to forming an arc-shaped reinforcing rib on the rolling support sheet 2. The pressing groove 3 extends to the edge of the rolling support sheet 2 to form an arc-shaped tooth.

[0017] There are two rolling support plates 2 , which are respectively located at two ends of the pressing wheel 1 to better support the pressing wheel 1 .

[0018] The outer contour of the rolling support sheet 2 is circular, that is, the projection of the rolling support sheet 2 in the thickness direction is circular, and the rolling support sheet 2 is concentrically arranged with the pressing wheel 1, so that the rolling support sheet 2 can roll more smoothly.

[0019] In one embodiment, the two ends of the pressing wheel 1 are connected with end shafts 4, the end shafts 4 are fixedly connected to the pressing wheel 1, and the pressing wheel 1 is rotatably arranged on the seed drill through the end shafts 4. The rolling support sheet 2 is fixedly arranged on the end shafts 4, and the rolling support sheet 2 and the pressing wheel 1 roll synchronously.

[0020] In one embodiment, the two ends of the pressing wheel 1 are connected with end shafts 4, and the rolling support sheet 2 is installed on the end shaft 4 through bearings, so that the rolling support sheet 2 and the pressing wheel 1 can rotate independently. When the seeder is a hand-push semi-automatic seeder, and the operator pushes the seeder to travel on a hard road surface, since the rolling support sheet 2 supports the pressing wheel 1, the operator only needs to push the rolling support sheet 2 to rotate, and does not need to drive the pressing wheel 1 to roll, which is more labor-saving. Furthermore, the seeder is provided with a driving mechanism that drives the rolling support sheet 2 to rotate independently, so that the driving mechanism can drive the seeder to travel on a hard road surface through the rolling support sheet 2.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
