Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a mirror-finish plowshare structure. Background Technology

[0002] There are two types of existing mirror-finish plowshares. Figure 1 A combined mirror plowshare structure is presented, which is composed of front and rear plowshares. Figure 2 An integral mirror plowshare structure is presented, which is simple in structure but requires complete replacement, which is not conducive to the rational use of materials. In contrast, the assembly of the plowshare in modular mirror plowshare structures mostly adopts a tie rod + support bar assembly method, which is complex to assemble, requires high strength from the tie rods and the assembly structure, and does not allow for adjustment of the plowshare angle. Furthermore, the existing modular mirror plowshare structures use a straight-line fit between the front and rear plowshares, making interchangeable assembly with bar plows impossible. Utility Model Content

[0003] This invention discloses a mirror plow wall structure, aiming to solve the following problems in the prior art: 1. Existing combined mirror plows cannot achieve plow wall angle adjustment, and the assembly structure is complex, requiring high structural strength; 2. Existing combined mirror plows cannot be interchanged with bar plows.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A mirror-finish plowshare structure includes a front plowshare structure and a rear plowshare structure. The opposite ends of the front plowshare structure and the rear plowshare structure are respectively provided with an outwardly convex first arc-shaped surface and an inwardly concave second arc-shaped surface. The first arc-shaped surface and the second arc-shaped surface cooperate with each other. The front plowshare structure and the rear plowshare structure are connected by a pitch adjustment mechanism.

[0006] Preferably, the pitch adjustment mechanism includes a main plowshare, one end of which has three first bolt holes arranged in a triangular pattern. The front plow wall structure has second bolt holes that match the first bolt holes. A first bolt passes through the opposite first and second bolt holes, and a first nut is screwed onto the first bolt. One end of the main plowshare has at least three lugs, each lug having a third bolt hole. The centers of the third bolt holes are arranged along an arc. The rear plow wall structure opposite to the third bolt holes has a fourth bolt hole. A second bolt passes through the opposite third and fourth bolt holes, and a second nut is screwed onto the second bolt. After the main plowshare is connected to the front and rear plow wall structures, the first and second arc surfaces fit together.

[0007] Preferably, the outer diameter of the second bolt is smaller than the inner diameter of the third bolt hole and the fourth bolt hole, the inner diameters of the third bolt hole and the fourth bolt hole are the same, an elastic washer is provided between the bolt head of the second bolt and the outer port of the third bolt hole, and the second bolt passes through the elastic washer.

[0008] Preferably, the side of the main plowstock away from the front plow wall structure is connected to a plow side plate by two or more third bolts and matching third nuts, and a telescopic rod for adjusting the pitch angle of the rear plow wall structure is connected between the plow side plate and the bottom of the rear plow wall structure.

[0009] Preferably, the telescopic rod includes a first screw, a second screw, and a sleeve. The two ends of the inner wall of the sleeve are provided with internal threads in opposite directions. The opposite ends of the first screw and the second screw are respectively screwed to the two ends of the sleeve. The other ends of the first screw and the second screw are respectively connected to the plow side plate and the rear plow wall structure.

[0010] Preferably, there are two telescopic rods, namely a long telescopic rod and a short telescopic rod.

[0011] Preferably, a main plow column is provided between the plow side plate and the main plow support, and the main plow column is connected to the main plow support by two fourth bolts and a fourth nut.

[0012] Preferably, the front plow wall structure constitutes the basic structure of the grid plow. Multiple grid bars are assembled on one side of the first arc-shaped surface through the main plow support. The front plow wall structure is connected to the main plow support through the first bolt and the first nut. The lug of the main plow support is connected to the end of the grid bar through the fifth bolt. A gap is left between the fifth bolt and the corresponding connecting hole and a washer is provided.

[0013] The beneficial effects of this novel mirror-finish plowshare structure are as follows:

[0014] 1. The front plow wall structure of this new type has the same shape as the front plow wall structure of the existing bar plow. Therefore, after removing the rear plow wall structure, the bar plow can be quickly assembled without removing the front plow wall structure. In contrast, the existing modular mirror plow requires complete disassembly before the bar plow can be installed. This improvement saves materials used in the construction of the bar plow and also improves the replacement efficiency of the bar plow.

[0015] 2. This new type of structure is simple and has high strength. By setting up a pitch adjustment mechanism, the pitch angle of the rear plow wall structure can be easily adjusted within a certain range, which provides further convenience for the use of mirror plows.

[0023] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0024] The following embodiments can be understood as a part of the local structure or method of the present invention, or as a combination of embodiments to explain the connotation of a larger range of structures or methods of the present invention.

[0025] Example 1

[0026] A mirror-finish plowshare structure, such as Figure 3-6 As shown, it includes a front plow wall structure 1 and a rear plow wall structure 3. The opposite ends of the front plow wall structure 1 and the rear plow wall structure 3 are respectively provided with an outwardly convex first arc-shaped surface 4 and an inwardly concave second arc-shaped surface 2. The first arc-shaped surface 4 and the second arc-shaped surface 2 cooperate with each other. The front plow wall structure 1 and the rear plow wall structure 3 are connected by a pitch adjustment mechanism.

[0027] In this embodiment, the opposite ends of the front plowshare structure 1 and the rear plowshare structure 3 are respectively provided with an outwardly convex first arc-shaped surface 4 and an inwardly concave second arc-shaped surface 2, which is different from the straight structure of the opposite ends of the existing front plowshare 01 and the existing rear plowshare 02 (e.g., Figure 1As shown in the diagram, although the improvement may not appear significant, the difference in effect is substantial. Specifically, the improved front plowshare structure matches the shape of the existing slat plowshare structure. Therefore, after removing the rear plowshare structure, the slat plow can be quickly assembled without dismantling the front plowshare structure. This is achieved by connecting several slats to the front of the first arc-shaped face via the main plowshare and simultaneously connecting them to the front plowshare structure, thus forming the slat plow (the connection method can be referenced from the assembly method of existing slat plows). In contrast, the existing modular mirror plow requires complete dismantling before the slat plow can be installed. This improvement saves materials used in constructing the slat plow and increases the efficiency of slat plow replacement. Furthermore, the new design, by incorporating a pitch adjustment mechanism, allows for easy adjustment of the pitch angle of the rear plowshare structure within a certain range, further enhancing the convenience of using the mirror plow.

[0028] Example 2

[0029] like Figure 3-6 As shown, the pitch adjustment mechanism includes a main plowshare 14, one end of which is provided with three first bolt holes 19 arranged in a triangle, and the front plow wall structure 1 is provided with second bolt holes (e.g., ...) that match the first bolt holes 19. Figure 3 As shown in the figure (not marked), the first bolt (as shown in the figure) passes through the first bolt hole 19 and the second bolt hole respectively. Figure 5 As shown), a first nut is screwed onto the first bolt; one end of the main plowshare 14 is provided with at least three lugs, each lug being provided with a third bolt hole 20 (as shown). Figure 6 As shown), the centers of the third bolt holes are arranged along an arc (see...). Figure 6 The arc-shaped arrangement trajectory 21 shown in the figure has a fourth bolt hole on the rear plow wall structure 3 opposite to the third bolt hole 20. A second bolt 15 passes through between the opposite third and fourth bolt holes, and a second nut is screwed onto the second bolt 15. After the main plow support is connected to the front and rear plow wall structures, the first and second arc surfaces fit together. The main plow support is a commonly used structure, and its shape and structure are detailed in [reference needed]. Figure 6 As shown, any content not mentioned can be found in existing technologies.

[0030] like Figure 5 As shown, the outer diameter of the second bolt 15 is smaller than the inner diameter of the third bolt hole 20 and the fourth bolt hole. The inner diameters of the third bolt hole 20 and the fourth bolt hole are the same. An elastic pad (a common structure, not shown in the figure) is provided between the bolt head of the second bolt 15 and the outer port of the third bolt hole 20. The second bolt 15 passes through the elastic pad.

[0031] like Figure 5As shown, the main plow support 14 is connected to a plow side plate 13 on the side away from the front plow wall structure 1 by two or more third bolts and matching third nuts. The plow side plate 13 is connected to the bottom of the rear plow wall structure 3 by a telescopic rod for adjusting the pitch angle of the rear plow wall structure.

[0032] In this embodiment, since the outer diameter of the second bolt 15 is smaller than the inner diameter of the third bolt hole 20 and the fourth bolt hole, the extension or shortening of the telescopic rod will not cause mutual interference between the second bolt and the third bolt hole and the fourth bolt hole within a certain range. After adjusting the pitch angle of the plow wall structure by extending or shortening the telescopic rod, tighten the second bolt and the second nut to fix the pitch angle.

[0033] Example 3

[0034] like Figure 5 As shown, the telescopic rod includes a first screw 17, a second screw 16, and a sleeve 18. The inner walls of the sleeve 18 are provided with internal threads with opposite directions of rotation at both ends. The opposite ends of the first screw 17 and the second screw 16 are respectively screwed to the two ends of the sleeve 18. The other ends of the first screw 17 and the second screw 16 are respectively connected to the plow side plate 13 and the rear plow wall structure 3. The connection method can be hinged or connected by fastening bolts. The latter requires a certain gap between the fastening bolts and the connection holes of the plow side plate and the rear plow wall structure to allow room for adjustment of the angle.

[0035] like Figure 5 As shown, there are two telescopic rods, namely a long telescopic rod 9 and a short telescopic rod 8, which facilitates more stable fixation of the rear plow wall structure after adjusting the angle of the rear plow wall structure.

[0036] In this embodiment, when the telescopic rod is in use, the first screw and the second screw can be moved simultaneously toward or away from the sleeve by rotating the sleeve, thereby realizing the adjustment of the pitch angle of the rear plow wall structure.

[0037] Example 4

[0038] like Figure 5 As shown, a main plow column 11 is also provided between the plow side plate 13 and the main plow support 14. The main plow column 11 is connected to the main plow support 14 by two fourth bolts and a fourth nut. The connection method of the main plow column is a common technology. Any content not mentioned is solved by existing solutions.

[0039] Example 5

[0040] like Figure 4 , 5As shown, the front plow wall structure 1 constitutes the basic structure of the grid plow. On one side of the first arc-shaped surface 4, multiple grid bars are assembled through the main plow support 14 (the connection method can refer to the connection method between the main plow support and the rear plow wall structure, the difference being that they are replaced with grid bars 6). The front plow wall structure 1 is connected to the main plow support 14 through the first bolt and the first nut (after connection, one end of the grid bar is in contact with the first arc-shaped surface).

[0041] In this embodiment, the lugs of the main plowshare are connected to the ends of the grid bars 6 by a fifth bolt. A gap is left between the fifth bolt and the corresponding connecting hole and a gasket is provided. At this time, the position, posture and angle of each grid bar can be adjusted as needed to improve the convenience of use.
