Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and specifically relates to a novel flap plow. Background Technology

[0002] In the current field of small agricultural machinery, the plowshare plow is mostly used for tilling farmland. The main function of this type of plow is to turn and break up the soil. Its structure is similar to that of a moldboard plow, with an angle adjustment device located at the rear of the plow blades. This device allows for adjustment of the plow blades' working state. However, this type of plow has structural drawbacks in the existing technology, which are as follows:

[0003] 1. The overall structure is complex, leading to a higher failure rate and hindering use and subsequent maintenance; 2. The existing plow blade adjustment device is complex, making it difficult to operate when adjusting the tilt angle of the plow; 3. When the existing plow blades are fixed, they are directly connected to the tilting shaft. When adjusting the tilt angle, the entire plow blade is tilted by controlling the rotation of the tilting shaft. However, this design results in a small working surface for the plow blades, which cannot be expanded; 4. Most existing plow blades are single-blade fixed, but the plow tip is a vulnerable part. If the plow tip is damaged, the entire plow must be replaced, resulting in wasted operating costs.

[0004] In response to the technical problems mentioned above, the technical problem that urgently needs to be solved by those skilled in the art is: to design a new flap plow that can be formed with a relatively simple structure, is easy to manufacture and assemble, and can be used in a variety of plowing environments. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, this utility model proposes a plow with interlocking blades. By simplifying the overall structure of the plow body and facilitating its manufacture, it drives the plow blades to swing angle synchronously through an overall swing structure. Based on the existing design, it improves the working surface of the plow blades to swing, while also improving its structural strength and preventing the increase in usage costs caused by overall replacement.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A novel plowshare includes a front wheel articulation frame and a rear wheel articulation frame, with a yaw linkage hinged between the two frames. The front and rear wheel articulation frames are used to fix the front and rear wheels, respectively. A transmission drive box is provided corresponding to the front and rear wheels, and the two transmission drive boxes are connected as one unit via a drive linkage assembly. Either the front or rear transmission drive box is connected to an external engine. A plowshare fixing seat is provided on the rear wheel articulation frame, and a drive shaft is fixed on the plowshare fixing seat. The front end of the drive shaft has a vertically downward-sloping bend, and a plowshare assembly is fixed on the vertically downward-sloping bend. The plowshare assembly includes a plowshare base, on which plowshares and a plow tip are fixed. A connecting rod is provided on the drive shaft, and the end of the connecting rod is directly or indirectly connected to an external drive rod.

[0008] The plow blade fixing seat is fixed on the plow blade swing rod, the plow blade swing rod is hinged to the rear wheel hinge frame, the plow blade swing rod is hinged to a nut seat, a screw is inserted into the nut seat, and the bottom of the screw rests on the rear wheel hinge frame or the yaw linkage.

[0009] The drive linkage assembly includes a front drive shaft, a middle drive shaft, and a rear drive shaft. A front universal joint is provided between the front drive shaft and the middle drive shaft, and a rear universal joint is provided between the middle drive shaft and the rear drive shaft.

[0010] The rear wheel articulation frame and the yaw linkage are connected by a controllable locking positioning component.

[0011] The external drive rod is connected to the handrail, which is fixed to the engine base, and the engine base is fixed to the front wheel hinge frame. The external drive rod is hinged to the drive handle, which is driven by the angular swing member and the swing rod.

[0012] The rear wheel hinge frame is provided with a rear reinforcing rod, which is connected to the plow blade fixing seat to achieve overall reinforcement of the plow blade fixing seat.

[0013] This utility model has the following advantages: It discloses a novel plowshare, in which a yaw linkage is hinged between a front wheel articulation frame and a rear wheel articulation frame; the front wheel articulation frame and the rear wheel articulation frame are respectively used to fix the front wheel and the rear wheel; a transmission drive box is respectively provided for the front wheel and the rear wheel, and the two transmission drive boxes are connected as one unit through a drive linkage assembly; either the front wheel transmission drive box or the rear wheel transmission drive box is connected to an external engine; the above structure can achieve synchronous linkage of the front and rear wheels and use the same drive device, the drive structure is simple, and it is easy to assemble. Furthermore, it has a low failure rate and is easy to maintain during subsequent use; the rear wheel hinge frame is equipped with a plow blade fixing seat, and a drive shaft is fixed on the plow blade fixing seat. The front end of the drive shaft is equipped with a vertically downward-sloping bend, and a plow blade base is fixed on the vertically downward-sloping bend. The plow blade base is fixed with the plow blade and the plow tip. This downward-sloping design can increase the overall working surface of the plow blade and the plow tip, and improve plowing efficiency; this utility model also connects a swing rod to the drive shaft. The end of the swing rod is connected to an external drive rod. When adjusting the swing angle of the plow blade, no manual operation is required, resulting in high working efficiency.

[0020] The present invention will be further described below through embodiments. Those skilled in the art can refer to the embodiments for implementation, and can also make technical improvements and innovations based on the existing technical solutions.

[0021] Example 1:

[0022] A novel flap plow includes a front wheel hinge frame 3 and a rear wheel hinge frame 4, with a yaw linkage 2 hinged between the front wheel hinge frame 3 and the rear wheel hinge frame 4; the front wheel hinge frame 3, the rear wheel hinge frame 4, and the yaw linkage 2 can swing relative to each other after being connected.

[0023] The front wheel articulation bracket 3 and the rear wheel articulation bracket 4 are used to fix the front wheel 6 and the rear wheel 7, respectively. The front wheel 6 and the rear wheel 7 are of equal diameter and are all narrow wheels. Figure 1 As shown, the front wheel 6 and the rear wheel 7 have the same overall structure. Taking the front wheel as an example, the front wheel 6 adopts an annular wheel body 61. Several gripping teeth 62 are evenly distributed on the outer diameter of the annular wheel body 61. This structure enables the plow to grip and move on the ground. The above structure forms the support frame of the new plow, which is simple in structure, easy to manufacture, and has a low failure rate.

[0024] The front wheel articulation frame 3 includes a front support frame 31 and a front control arm 32. A front wheel transmission drive box 63 is mounted on the front support frame 31, and a driven wheel 64 is mounted on the front wheel transmission drive box 63. The driven wheel 64 is used to connect to an external engine 11. A rear wheel transmission drive box 71 is mounted on the rear wheel 7, and a rear drive shaft 72 is connected to the rear wheel transmission drive box 71. To achieve synchronous driving of the front wheel 6 and rear wheel 7 from the same drive source, the two transmission drive boxes are connected as one unit via a drive linkage assembly 5. In this embodiment, the drive linkage assembly 5 includes a front drive shaft 53, a front universal joint 51, a rear universal joint 52, and a rear drive shaft 72. In this embodiment, the front drive shaft 53 is connected to the front wheel transmission drive box 63, and the rear drive shaft 72 is connected to the rear wheel transmission drive box 71. The present invention has an engine base 1 welded on the front support frame 31, and the engine 1 is fixed by the engine base 1.

[0025] The key design feature of this invention lies in the following: a plowshare fixing seat 92 is provided on the rear wheel hinge frame 4, and a drive shaft 94 is fixed on the plowshare fixing seat 92. A vertically downward-sloping bending portion 93 is provided at the front end of the drive shaft 94, and a plowshare assembly 9 is fixed on the vertically downward-sloping bending portion 93. The plowshare assembly 9 includes the plowshare fixing seat 92, and the plowshare fixing seat is bolted to the plowshare 90 and the plow tip 91. By separately setting the plowshare 90 and the plow tip 91, they can be replaced independently when either the plowshare 90 or the plow tip 91 is damaged, minimizing maintenance costs. This invention employs a downward-sloping design for the drive shaft 94, which allows the position of the plow tip 91 to be adjusted downwards. During tilling operations, this increases the tilling area and improves tilling efficiency. Simultaneously, the bent structure of the drive shaft 94 significantly enhances its axial strength, preventing deformation when encountering compacted soil or impacted by hard objects.

[0026] In this invention, a connecting rod 96 is connected to a drive shaft 94. The end of the connecting rod 96 is directly or indirectly connected to an external drive rod. To facilitate the vertical swing adjustment of the plow blade 90 and the plow tip 91 in this device, the plow blade fixing seat 81 is fixed to the plow blade swing rod 8. The plow blade swing rod 8 is hinged to the rear wheel hinge frame 4. A nut seat 82 is hinged to the plow blade swing rod 8. A screw 83 is inserted into the nut seat 82. The bottom of the screw 83 rests on the rear wheel hinge frame 3. A handwheel 84 is provided on the top of the screw 83. The elevation angle of the plow blade fixing seat 81 and the entire plow blade assembly 9 can be adjusted by adjusting the handwheel 84.

[0027] With the above structural configuration, the tail end of the drive shaft 94 is connected to one end of the swing rod 97 via the connecting rod 96. The swing rod 97 is hinged to the plow blade swing rod 8, and the other end of the swing rod 97 is hinged to the drive handle 98. The drive handle 98 is connected to the external drive rod 99.

[0028] In this embodiment, the external drive rod 99 is connected to the handrail 12, the handrail 12 is fixed on the engine base 1, and the engine base 1 is welded and fixed on the front wheel hinge frame 3; the external drive rod 99 is hinged to the drive handle 98, and the drive handle 98 is hinged to the connecting rod 96 through the swing rod 97 and realizes the drive; the swing rod 97 is an angle swinging component.

[0029] Based on the above structural setup, the same design as the prior art is that the rear wheel articulation frame 4 and the yaw linkage 2 are connected by a controllable locking positioning component 10. When the entire rear wheel articulation frame 4 drives the rear wheel 7, plow blade swing rod 8, and plow blade assembly 9 to swing and adjust, it can be locked and positioned by the controllable locking positioning component 10. Since this positioning component is prior art, it will not be described in detail here.

[0030] Furthermore, to improve the overall rigidity of the entire rear wheel articulation frame 4, the rear wheel articulation frame 4 is provided with a rear reinforcing rod 73. The rear reinforcing rod 73 is connected to the plow blade fixing seat 81 to achieve overall reinforcement of the plow blade fixing seat 81. This structure can ensure the stability when the plow blade swings and adjusts.
