DETAILED DESCRIPTION

[0027] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0028] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] like Figure 1-5 As shown, a broad bean fixed-distance planting device includes a frame 1, a transmission shaft 5 is horizontally rotatably arranged on the frame 1, and a first rotating disk 3 and a second rotating disk 9 are correspondingly arranged at both ends close to the transmission shaft 5, wherein the first rotating disk 3 and the second rotating disk 9 are both connected to the transmission shaft 5 through a connecting flange and can rotate with the transmission shaft 5. The second rotating disk 9 is hinged to an eccentric disk 10 through a plurality of connecting rods 8, and the plurality of connecting rods 8 are evenly spaced around the circumference of the second rotating disk 9, and the plurality of connecting rods 8 are arranged near the edge of the second rotating disk 9, and the eccentric disk 10 is rotatably connected to the eccentric supporting plate 11 through a supporting wheel group arranged on the eccentric supporting plate 11, and the eccentric supporting plate 11 is arranged on the frame 1, therefore, the eccentric supporting plate 11 and the supporting wheel group thereon do not rotate with the transmission shaft 5, and the eccentric disk 10 rotates under the drive of the second rotating disk 9, and generates relative rolling with the supporting wheel group, therefore, there is no power input at the supporting wheel group, and it only plays the role of limiting the support of the eccentric disk 10.

[0030] A plurality of support rods 7 are also connected between the first rotating disk 3 and the second rotating disk 9. The plurality of support rods 7 are evenly spaced along the circumference of the first rotating disk 3 or the second rotating disk 9. One end of each support rod 7 is rotatably arranged on the first rotating disk 3 through a bearing, and the other end is also rotatably arranged on the second rotating disk 9 through a bearing and this end passes through the second rotating disk 9 and is fixedly connected to one end of the connecting rod 8. In this way, the rotation of the connecting rod 8 will cause the support rod 7 to rotate. A plurality of planting duckbill assemblies 4 are spaced along the length direction of the support rod 7. When the above-mentioned support rod 7 rotates, the planting duckbill assemblies 4 will rotate around the support rod 7. The eccentric setting between the above-mentioned eccentric disk 10 and the second rotating disk 9 can make the planting duckbill assemblies 4 always face downward to ensure that they are vertically inserted into the soil when running to the lowest position. A collision component 6 is also connected between the plurality of planting duckbill assemblies 4. Through the contact and cooperation between the collision component 6 and the duckbill opening disk 12, the planting duckbill assembly 4 inserted into the soil is opened, and the broad beans inside it are buried in the soil.

[0031] The above-mentioned duckbill opening disk 12 is arranged on the transmission shaft 5 between the first rotating disk 3 and the second rotating disk 9, and can rotate with the transmission shaft 5. During the rotation process, due to the existence of the eccentric distance with the eccentric disk 10, the duckbill opening disk 12 squeezes the lowest collision component 6, thereby opening the planting duckbill assembly 4.

[0032] In the actual design process, the design of the above-mentioned eccentricity is related to the movement trajectory of the collision component 6 and the movement trajectory of the duckbill opening disk 12. The setting of the eccentricity is to ensure that the collision component 6 can abut against the duckbill opening disk 12 when moving to the lowermost position and by the extrusion force, the collision component 6 can link the duckbill assembly 4 to open.

[0033] Furthermore, the structure of the planting duckbill assembly 4 specifically includes a first duckbill flap 401 and a second duckbill flap 402. The first duckbill flap 401 is fixed to the support rod 7 by screws or bolts. An elastic connector is provided between the lower part of the second duckbill flap 402 and the lower part of the first duckbill flap 401. The elastic connector closes the first duckbill flap 401 and the second duckbill flap 402 under the action of its elastic force. The upper part of the second duckbill flap 402 is connected to the collision component 6 through a swing lever 13. When the collision component 6 collides with the duckbill opening plate 12, it can overcome the elastic force of the elastic connector to separate the first duckbill flap 401 from the second duckbill flap 402 and drop the broad beans inside them.

[0034] Furthermore, the circumferential edge of the duckbill opening disk 12 is a wavy arc edge, which is approximately petal-shaped. The collision component 6 includes a collision shaft 602 and a collision bearing 601. The collision shaft 602 is connected to the second duckbill flap 402 through a swing lever 13. The collision bearing 601 is rotatably arranged on the collision shaft 602. The arrangement of the collision bearing 601 can avoid severe friction between the duckbill opening disk 12 and the collision shaft 602. The maximum diameter position of the duckbill opening disk 12 touches and squeezes the collision bearing 601. The collision bearing 601 reduces friction by rotating itself, and at the same time, the collision shaft 602 is caused to swing under the action of the squeezing force. The swing lever 13 connected to the collision shaft 602 will pull the second duckbill flap 402 to separate from the first duckbill flap 401.

[0035] Furthermore, the elastic connecting member is a spring 403, which has a simple structure, is easy to implement, and is convenient to install, and is more suitable for the occasions of the present application.

[0036] Furthermore, in order to ensure that the second duckbill flap 402 is evenly stressed, two springs 403 are provided. The two springs 403 are symmetrically arranged on both sides of the planting duckbill assembly 4. The two springs 403 pull the second duckbill flap 402 on the left and right sides at the same time, which can avoid the second duckbill flap 402 from getting stuck due to uneven stress.

[0037] Furthermore, as to how the eccentric disk 10 and the supporting wheel group on the eccentric support plate 11 can ensure the rotation and the supporting function at the same time, specifically, a circular cavity 15 is provided in the middle of the eccentric disk 10, and the circumferential surface of the supporting wheel group abuts against the inner surface of the circular cavity 15, and the supporting wheel is rotatably arranged on the eccentric support plate 11, so that the eccentric distance between the eccentric disk 10 and the second rotating disk 9 can be ensured, and at the same time, it can be ensured that the eccentric disk 10 only rotates.

[0038] Furthermore, the above-mentioned supporting wheel group includes at least three rollers 14. The present application sets three rollers 14 according to specific circumstances. The three rollers 14 are arranged at circumferential intervals along the circular cavity 15, and the positions of the three rollers 14 are staggered from the position through which the transmission shaft 5 passes. The three rollers 14 can support the eccentric disk 10, and at the same time can reduce the number of rollers 14, reduce the occupied space in the circular cavity 15, and avoid interference with the transmission shaft 5.

[0039] Furthermore, a transmission sprocket 2 is provided at one end of the transmission shaft 5, and the transmission sprocket 2 and the external power component can realize power transmission through chain transmission, and the external power is input to drive the transmission shaft 5 to rotate.

[0040] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0041] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
