Description

Technical Field

[0001] This application relates to the field of micro-tiller assembly technology, and specifically discloses a support frame for assembling a micro-tiller body. Background Technology

[0002] Mini tillers, small agricultural machines used for cultivating land, are powered by small diesel or gasoline engines and are widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. Mini tillers can move freely in the fields, making them convenient for users to operate and store.

[0003] A mini tiller mainly consists of working parts, a frame, a transmission system, and a power system. During the tiller's movement, the rotary tillers rotate to till the land. As the tiller moves, the rotary tillers rotate in the direction of travel, and this rotation pulls the soil backward.

[0004] Assembly of mini tillers is typically performed on a workbench. Traditional assembly involves gradually mounting components onto the frame. The frame is initially placed on the workbench, and then the components are lifted and secured to the frame to complete the assembly. This process requires lifting the components above the height of the frame before assembly can begin. Currently, there is no support frame in the technology that allows for inverting the frame for mini tiller assembly.

[0005] This invention provides a support frame for assembling the body of a micro-tiller, in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that there is no support frame in the traditional assembly process of micro-tillers that can be used to invert the frame for assembly.

[0007] To achieve the above objectives, the basic solution of this utility model provides a support frame for assembling a micro-tiller body, including two columns and a positioning structure vertically slidably connected between the two columns. The positioning structure includes a positioning rod, several positioning plates disposed on the positioning rod, and several positioning clamps disposed at the bottom of the positioning plates. The two ends of the positioning rod are vertically slidably connected to the columns on the same side, and a driving structure is provided between the two columns for driving the two ends of the positioning rod to slide vertically and synchronously.

[0008] Furthermore, the positioning plate is slidably connected to the positioning rod, and fasteners for abutting the positioning rod are detachably connected to the positioning plate.

[0009] Furthermore, the bottom of the positioning plate has an upward-facing guide groove for accommodating and slidingly connecting the positioning rod, and one side of the positioning plate has an internal threaded hole that extends into the guide groove. The fastener is a bolt that is threadedly connected to the internal threaded hole and can abut against the wall of the positioning rod.

[0010] Furthermore, the top two sides of the positioning rod are provided with limiting grooves downward along the sliding direction of the positioning plate, and the positioning plate inside the guide groove protrudes inward to form a limiting platform that fits with the limiting groove.

[0011] Furthermore, the positioning fixture includes guide plates fixed to both sides of the bottom of the positioning plate, clamping plates slidably connected to the bottom of the guide plates perpendicular to the extension direction of the positioning rod, and positioning components disposed on the clamping plates and used to abut against the guide plates. The clamping plates have vertical grooves, and a screw rod passing through the vertical groove is provided between the two clamping plates. Limiting nuts are screwed into the screw rods located on both sides of the clamping plates.

[0012] Furthermore, the drive structure includes a support rod fixed between the top ends of the two columns, a guide wheel rotatably connected to the support rod, pulleys rotatably connected to the top ends of the two columns, a handwheel on one column, an input pull rope with both ends wound around the guide wheel and the handwheel respectively, an output pull rope one with one end wound around the guide wheel and the other end fixed to the same side end of the positioning rod via a pulley on one side, and an output pull rope two with one end wound in the opposite direction around the guide wheel and the other end fixed to the same side end of the positioning rod via a pulley on the other side.

[0013] Furthermore, each of the columns has a vertical groove for the end of the positioning rod to extend into and slide vertically within it, and the end of the positioning rod extending out of the vertical groove is fixedly connected to the ends of output pull rope one and output pull rope two, respectively.

[0014] The principle and effect of this solution are as follows:

[0015] Compared with the prior art, this utility model, after the frame is installed, gradually moves the components to the bottom of the frame and installs them on the frame. As the components are installed, turning the handwheel pulls the input rope and rotates the guide wheel. The rotation of the guide wheel retracts the output rope one and output rope two respectively. The output rope one and output rope two, which are wound in opposite directions, pull the positioning rod upward simultaneously. After clearing the space, the components below are installed. This solves the problem of the lack of a support frame that can be inverted for assembly in the traditional assembly of micro-tillers. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] The reference numerals in the accompanying drawings include: positioning rod 1, positioning rod 2, positioning plate 3, guide plate 4, clamping plate 5, handwheel 6, center partition 7, and guide wheel 8.

[0022] A support frame for assembling the body of a mini tiller, implementing, for example Figure 1 , Figure 2 and Figure 3 As shown:

[0023] It includes two columns and a positioning structure installed between the two columns that can slide vertically.

[0024] Both columns have a vertical groove, which does not extend to either end of the column. The positioning structure includes a positioning rod 1, three sets of positioning plates 3 mounted on the positioning rod 1, and three sets of positioning clamps mounted on the bottom of the positioning plates 3.

[0025] The positioning rod 1 has two ends that extend into vertical grooves in the column on the same side. The positioning plate 3 is slidably mounted on the positioning rod 1. Specifically, the bottom of the positioning plate 3 has an upward-facing guide groove for accommodating the positioning rod 1. The positioning plate 3 is mounted on the positioning rod 1 via the guide groove and slides along the length of the positioning rod 1. Furthermore, the top two sides of the positioning rod 1 have downward-facing limiting grooves along the sliding direction of the positioning plate 3. The positioning plate 3 protrudes inward from the guide groove to form a limiting platform that fits into the limiting groove. The bottom of the limiting platform is supported on the positioning rod 1, and the drop structure disperses the contact surface, providing stable support for the positioning plate 3.

[0026] On the right side of the positioning plate 3, there are two internal threaded holes that extend into the guide groove. Fasteners are installed on the positioning plate 3 through the internal threaded holes. In this embodiment, the fastener is a bolt that can be threadedly connected to the internal threaded hole. By screwing the bolt into the internal threaded hole, the inner end of the bolt is pressed against the wall of the positioning rod 1 to fix the position of the positioning plate 3.

[0027] like Figure 1 and Figure 3As shown, the positioning fixture includes guide plates 4 welded to both sides of the bottom of the positioning plate 3, a clamping plate 5 installed on the bottom of the guide plate 4 and slidable along the extension direction perpendicular to the positioning rod 1, and a positioning element installed on the clamping plate 5. Specifically, the bottom of the guide plate 4 has a T-shaped groove perpendicular to the extension direction of the positioning rod 1, and the top of the clamping plate 5 has a T-shaped slider that slides within the T-shaped groove, with the thickness of the T-shaped slider being greater than the thickness of the clamping plate 5. A second internally threaded hole, penetrating to the top surface of the T-shaped groove, is provided on the portion of the T-shaped slider that extends beyond the clamping plate 5. The positioning element is a second bolt, which can be screwed into the second internally threaded hole and abuts against the top surface of the T-shaped groove. Furthermore, the clamping plate 5 has a vertical groove, and a screw rod passing through the vertical groove is installed between the two clamping plates 5. Limiting nuts are screwed into the screw rod located on both sides of the clamping plate 5.

[0028] In this embodiment, a drive structure is also installed between the two columns to drive the two ends of the positioning rod 1 to slide vertically and synchronously within the vertical groove. The drive structure includes a support rod fixed to the top ends of the two columns by bolts, a bracket mounted on the support rod, a guide wheel 8 mounted on the bracket and rotatable, pulleys mounted on the top ends of the two columns and rotatable, a handwheel 6 mounted on the left column, and an input pull rope, an output pull rope one, and an output pull rope two.

[0029] Specifically, the axis of the guide wheel 8 is perpendicular to the extension direction of the support rod in the horizontal direction. One end of the input pull rope is wound around the guide wheel 8, and the other end is wound around the handwheel 6. One end of the output pull rope is wound around the guide wheel 8, and the other end is fixed to the left end of the positioning rod 1 via the left pulley. One end of the output pull rope is wound around the guide wheel 8 in the opposite direction, and the other end is fixed to the right end of the positioning rod 1 via the right pulley. Figure 1 and Figure 2 As shown, a central partition 7 is also fixedly installed on the support rod. Edge partitions are also installed on both sides of the central partition 7. Both the central partition 7 and the edge partitions have through holes for the guide wheel 8 to pass through. The guide wheel 8 is divided into four sections by the central partition 7 and the edge partitions. The input pull rope, the output pull rope one, and the output pull rope two are respectively wound on different sections.

[0030] Furthermore, a guide pulley is installed on the left-side column, and the input pull rope is wound around the guide pulley for installation.

[0031] When using this utility model, such as Figure 3 As shown, the position of the positioning plate 3 is pre-adjusted, and the spacing of the clamping plate 5 at the bottom of the guide plate 4 is adjusted. The screw passes through the mounting hole on the frame to position the frame.

[0032] Next, the components are gradually moved to the bottom of the frame and installed on the frame. As the components are installed, the handwheel 6 is turned, and the guide wheel 8 is pulled and rotated by the input pull rope. The output pull rope 1 and output pull rope 2 are respectively gathered by the rotation of the guide wheel 8. The output pull rope 1 and output pull rope 2, which are wound in opposite directions, are simultaneously pulled upward by the positioning rod 1. After clearing the position, the components below are installed.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
