Description

Technical Field

[0001] This utility model relates to the field of tobacco planting equipment technology, specifically to a deep tillage tool for tobacco fields. Background Technology

[0002] Every year, tobacco farmers till and loosen the soil in their tobacco fields, a crucial step in the tobacco cultivation process. Due to the steep slopes and hard soil in hilly areas, sufficient tillage depth is essential. Deep tillage exposes the subsoil, increasing its fertility and promoting the growth of organic matter.

[0003] Currently, mini-tillers are commonly used for deep tillage of tobacco fields due to their fast tillage speed. However, the blades of these mini-tillers are smooth, creating a smooth bottom surface that hinders soil permeability and aeration. These issues result in poor soil permeability and aeration, leading to unsatisfactory tillage outcomes in tobacco fields. Utility Model Content

[0004] The purpose of this utility model is to provide a deep tillage tool for tobacco fields, which solves the problem that existing tillage tools make the bottom of the soil smooth during tillage, which is not conducive to soil water and air permeability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tobacco field deep tillage tool, comprising: a cutter shaft, a connecting plate, and a rotary tillage assembly;

[0006] The cutter shaft is tubular;

[0007] Both ends of the cutter shaft are fixedly connected to connecting plates, and a first shaft hole is opened in the middle of the connecting plate;

[0008] Rotary tillage components are fixedly installed on the outer sides of both connecting plates;

[0009] The rotary tillage assembly includes three rotary tillage blades arranged circumferentially along the blade shaft. Each rotary tillage blade has a plurality of teeth on the side opposite to the blade shaft, and the teeth are arranged in a serrated pattern along the length of the rotary tillage blade.

[0010] The principle and effects of the above technical solution are as follows: During use, the blade shaft is fixedly installed on the output shaft of the micro-tiller. The micro-tiller drives the blade shaft to rotate, which in turn drives the rotary tillers to break up the soil. Because the rotary tillers have serrated teeth on the side opposite the blade shaft, during rotary tillage, the teeth cut into the soil at the bottom, creating a rough surface that enhances the permeability and aeration of the soil. Simultaneously, the teeth make it easier for the rotary tillers to cut the soil, improving their ability to break up the soil.

[0011] The present invention is further configured such that the rotary tiller blade has a first bent section, a straight section, a second bent section, and a third bent section arranged sequentially. The first bent section and the third bent section are both bent toward the side away from the connecting plate, and the second bent section is bent toward the direction close to the connecting plate. The side of the first bent section of each rotary tiller blade close to the connecting plate overlaps the side of the straight section of another rotary tiller blade away from the connecting plate. The three rotary tiller blades are arranged in a triangle. The connecting plate has three first mounting holes along its circumference. The first bent section and the straight section each have a second mounting hole. The two second mounting holes correspond to two adjacent first mounting holes on the corresponding side. Bolts are inserted into the corresponding second mounting holes and the corresponding first mounting holes on the overlapping straight section and the first bent section. The rotary tiller blade is connected to the connecting plate on the corresponding side by the bolts.

[0012] By adopting the above technical solution, the three rotary tiller blades, with their second and third bending sections, increase their working range for breaking up soil. The blades are connected to the connecting plate via bolts, facilitating disassembly and replacement. Furthermore, because the side of the first bending section of each blade closest to the connecting plate overlaps the side of the straight section of another blade furthest from the connecting plate, the bolts tighten, causing the straight section to press against the overlapping first bending section. This results in greater overall stability and a more secure connection between the three rotary tiller blades.

[0013] The present invention is further configured such that the first mounting holes on the two connecting plates are misaligned.

[0014] By adopting the above technical solution, the first mounting holes on the two connecting plates are misaligned, so that the rotary blades of the two adjacent rotary tillage components are staggered, thereby improving the soil breaking effect of the rotary tillage blades during use.

[0015] The present invention is further configured to include an end connector, the end connector comprising an end shaft and a mounting plate connected together, the mounting plate having a third mounting hole corresponding to the first mounting hole on the connecting plate and a second shaft hole corresponding to the first shaft hole, the mounting plate being connected to the connecting plate by bolts, the mounting plate and the connecting plate together clamping the first bent section and the straight section of the rotary tiller.

[0016] By adopting the above technical solution, the first bent section and the straight section of the rotary tiller blade are clamped together by the mounting plate and the connecting plate, thereby enhancing the overall stability of the rotary tiller assembly.

[0017] The present invention is further configured such that the cutting teeth are inclined in a direction away from the cutting axis.

[0018] By adopting the above technical solution, the cutting teeth are inclined away from the cutting axis, which facilitates the cutting of soil. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] A type of deep-plowing tool for tobacco fields, such as Figures 1-5As shown, the assembly includes: a blade shaft 1, connecting plates 2, and a rotary tillage assembly. The blade shaft 1 is tubular, and its cross-section is a hexagonal steel pipe. Connecting plates 2 are fixedly connected to both ends of the blade shaft 1. The connecting plates 2 are triangular plates, welded to the ends of the blade shaft 1. A first shaft hole 3, hexagonal in shape, is provided in the middle of the connecting plate 2 for easy connection to the hexagonal output shaft of the rotary tiller. Two positioning holes 4 are provided on the outer side of the blade shaft 1, located near the left and right ends respectively, facilitating locking of the blade shaft 1 by inserting positioning pins into the positioning holes 4 and the connecting holes on the output shaft of the rotary tiller. A rotary tillage assembly is fixedly installed on the outer sides of both connecting plates 2. The rotary tillage assembly includes three rotary blades 6 arranged circumferentially along the blade shaft 1. Each rotary blade 6 has several teeth 11 on the side facing away from the blade shaft 1. The teeth 11 are arranged in a serrated pattern along the length of the rotary blade 6, and are inclined away from the blade shaft 1. The rotary tiller blade 6 has a first bent section 7, a straight section 8, a second bent section 9, and a third bent section 10 arranged sequentially from the end of the rotary tiller blade 6 near the blade shaft 1 to the free end. The first bent section 7 and the third bent section 10 are both bent towards the side away from the connecting plate 2, while the second bent section 9 is bent towards the direction of the connecting plate 2. The side of the first bent section 7 of each rotary tiller blade 6 near the connecting plate 2 overlaps the side of the straight section 8 of another rotary tiller blade 6 away from the connecting plate 2. The three rotary tiller blades 6 are arranged in a triangle, and the triangular area enclosed by the intersection of the three rotary tiller blades 6 allows the output shaft of the micro-tiller to pass through. Because the straight section 8 abuts against the connecting plate 2, the rotary tiller blade 6 can be parallel to the connecting plate 2, thereby making the rotary tiller blade 6 perpendicular to the blade shaft 1. Because the first bent section 7 bends away from the connecting plate 2, the first bent section 7 can overlap the straight section 8 of another rotary tiller blade 6, and the first bent section 7 presses down on the straight sections 8 of the two rotary tiller blades 6. Three first mounting holes 12 are provided on the circumferential direction of the connecting plate 2. The three first mounting holes 12 correspond to the three corners of the triangular connecting plate 2, and the first mounting holes 12 on the two connecting plates 2 are staggered. Second mounting holes 13 are provided on both the first bent section 7 and the straight section 8. The two second mounting holes 13 correspond to the two adjacent first mounting holes 12 on the corresponding side. Bolts 14 are inserted into the corresponding second mounting holes 13 and the corresponding first mounting holes 12 on the overlapping straight section 8 and first bent section 7. The rotary tiller 6 is connected to the connecting plate 2 on the corresponding side by bolts 14.

[0027] To enhance the connection stability between the rotary tiller assembly and the connector, an end connector 5 is also included. The end connector 5 includes a connected end shaft 501 and a mounting plate 502. The mounting plate 502 is a triangular plate, and it has a third mounting hole 503 corresponding to the first mounting hole 12 on the connecting plate 2, and a second shaft hole 504 corresponding to the first shaft hole 3. The second shaft hole 504 is a hexagonal hole. The mounting plate 502 is connected to the connecting plate 2 by bolts 14. The mounting plate 502 and the connecting plate 2 together clamp the first bent section 7 and the straight section 8 of the rotary tiller 6.

[0028] Based on the above scheme, the number of rotary tillage components can be increased according to actual needs. For example, when three rotary tillage components are needed, two blade shafts 1 are set up, and the connecting plates 2 at one end of the two blade shafts 1 are close to each other. The two close connecting plates 2 are connected by bolts 14 and together clamp the first bent section 7 and straight section 8 of the rotary tillage blade 6 corresponding to the rotary tillage component. Each of the two blade shafts 1, at the ends that are far apart from each other, is connected to a rotary tillage component and an end connector 5. The connection method of the end connector 5 with the connecting plate 2 and the rotary tillage component is the same as in the above scheme and will not be repeated here.

[0029] Working Principle: During use, the blade shaft 1 is fixedly installed on the output shaft of the micro-tiller. The micro-tiller drives the blade shaft 1 to rotate, which in turn drives the rotary tiller blades 6 to break up the soil. Because the rotary tiller blades 6 have serrated teeth 11 on the side opposite to the blade shaft 1, during rotary tillage, the teeth 11 cut into the soil at the bottom, creating a rough surface that enhances the permeability and aeration of the soil. Simultaneously, the teeth 11 make it easier for the rotary tiller blades 6 to cut the soil, improving their ability to break up the soil, increasing the size of tilled soil particles, increasing tillage depth, improving soil permeability, and enhancing tillage efficiency. The three rotary tiller blades 6 have a second bending section 9 and a third bending section 10, increasing their working range for breaking up soil. The rotary tiller blades 6 are connected to the connecting plate 2 by bolts 14, facilitating disassembly and replacement. Furthermore, since the first bent section 7 of each rotary tiller 6 overlaps the side of the straight section 8 of another rotary tiller 6 away from the connecting plate 2, the straight section 8 abuts against the first bent section 7 it overlaps with under the tightening action of the bolt 14, thus making the three rotary tiller 6 more stable and firmly connected as a whole. Because the first mounting holes 12 on the two connecting plates 2 are staggered, the corresponding rotary tiller 6 of two adjacent rotary tiller assemblies are offset from each other, thereby improving the soil breaking effect of the rotary tiller 6 during use. The mounting plate 502 and the connecting plate 2 together clamp the first bent section 7 and the straight section 8 of the rotary tiller 6, thereby enhancing the overall stability of the rotary tiller assembly. Since the blade teeth 11 are inclined away from the blade shaft 1, it is convenient for the blade teeth 11 to cut the soil.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
