Detailed Implementation

[0015] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0016] This application provides a plow frame with adjustable plowing width, such as... Figure 1 and Figure 2 As shown, Figure 1 This is a front view of a plow frame with adjustable plowing width according to an embodiment of this application. Figure 2 This is a rear view of an adjustable plow frame according to an embodiment of the present application. The plow frame includes a crossbar 1, several plows 2, and a fixing component 3.

[0017] The crossbeam 1 is shaped like a long plate, and a long, narrow groove 11 is provided on the main extended surface at the top of the crossbeam 1.

[0018] The plow 2 includes a plow body 21, a protruding rod 22, a positioning rod 23, a positioning block 24, and a plow head. In some embodiments, each crossbeam 1 is connected to three plows 2.

[0019] The tail of the plow body 21 is designed as a semi-enclosed structure and is fitted over the outside of the cross frame 1. The upper and lower ends of the plow body 21 are respectively engaged with the upper and lower sides of the slot 11 and are slidably connected to the upper and lower sides of the slot 11 in the extending direction of the slot 11.

[0020] The protruding rod 22 is cylindrical in shape. One end of the protruding rod 22 is connected to the side of the plow body 21 extending in the thickness direction near the crossbeam 1, and the protruding rod 22 is threadedly connected to the plow body 21. The position of the protruding rod 22 can be determined according to actual needs; it can be placed on the outside of the plow body 21 or through the slot 11 on the inside of the plow body 21. The end of the protruding rod 22 away from the plow body 21 is connected to a disc-shaped positioning block 24 with an area larger than the cross-sectional area of ​​the protruding rod 22. The purpose of the threaded connection between the protruding rod 22 and the plow body 21 is to facilitate the installation of the plow body 21 and to allow the plow body 21 to move relatively over a longer distance on the crossbeam 1.

[0021] The positioning rod 23 is connected to the end of the protruding rod 22 away from the plow body 21, and the setting direction of the positioning rod 23 is perpendicular to the extension direction of the slot 11.

[0022] Specifically, such as Figure 3 As shown, Figure 3 for Figure 1 In the sectional view along direction AA, the length of the positioning rod 23 is greater than the distance between the protruding rod 22 and the upper end of the crossbeam 1. One end of the positioning rod 23 has an internal groove 231. The positioning block 24 is disposed in the internal groove 231 and is movably connected to the positioning rod 23 in the thickness direction of the crossbeam 1. That is, the relative position of the positioning rod 23 with respect to the protruding rod 22 is changed by the change in the relative position of the positioning block 24 and the internal groove 231.

[0023] The plowshare is located at the lower end of the plow body 21 and is fixedly connected to the plow body 21 through a curved plate-like structure.

[0024] The fixing component 3 includes several fixing shells 31 and fixing bases 32. The fixing shells 31 and fixing bases 32 are detachably connected. Figure 4 As shown, Figure 4 This is a schematic diagram of the fixing component in this embodiment. The fixing shell 31 is provided with a fixing seat 32 fixedly connected to the crossbeam 1. The upper end of the fixing seat 32 has a fixing groove for the fixing shell 31 to be embedded. When the fixing shell 31 is embedded in the fixing groove, the fixing shell 31 and the fixing seat 32 are connected by bolts. The fixing shell 31 has several positioning holes 311 for the positioning rod 23 to pass through, and each fixing shell 31 has three positioning holes 311. The upper end of the fixing shell 31 is provided with several handles 312.

[0025] Work process: such as Figure 3 and Figure 5 As shown, Figure 5 for Figure 3 The diagram shows the structure when the plowshare 2 is separated from the fixing component 3. When it is necessary to adjust the distance between the plowshare bodies 21, at least one plowshare body 21 is disconnected from the fixing shell 31, and one or more plowshare bodies 21 are slid on the slot 11 until the distance between two or more plowshare bodies 21 meets the farming requirements. When it is necessary to fix the relative position of the plowshare body 21 on the crossbeam 1, the positioning rod 23 is first passed through the positioning hole 311, then the fixing shell 31 is placed in the fixing slot, and then the fixing shell 31 is connected to the fixing seat 32 to fix the plowshare body 21.

[0026] This application provides an adjustable plow frame, including a crossbeam 1, a plow body 21, and several fixed housings 31. The plow body 21 is connected to a protruding rod 22. The protruding rod 22 is connected to a positioning rod 23. The fixed housings 31 have positioning holes 311 through which the positioning rods 23 pass. When it is necessary to adjust the distance between the plow bodies 21, at least one plow body 21 is disconnected from the fixed housing 31, and the plow body 21 slides on the slot 11. When it is necessary to fix the relative position of the plow bodies 21 on the crossbeam 1, the fixed housings 31 fix the plow body 21 to the crossbeam 1 through the cooperation of the positioning rods 23 and the positioning holes 311. In summary, this application embodiment can easily and conveniently adjust the distance between the plow bodies 21, thus solving the problem that the horizontal relative position between the plows in existing plow frames is difficult or even impossible to adjust.
