AI Technical Summary
Existing technologies are insufficient to effectively remove tobacco stem roots, leading to decreased soil fertility and increased pests and diseases, which in turn affects crop growth.
A novel rotary tiller is designed, comprising a rotating shaft and a tiller mechanism. The tiller mechanism consists of first and second support plates, which are V-shaped. The blades are inclined and the rotating shaft digs the soil from the base of the tobacco plant.
Effectively digging out the roots of tobacco stalks helps maintain soil fertility, prevent pests and diseases, and promote crop growth.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco stalk and root digging and harvesting technology, specifically a novel rotary tillage blade. Background Technology
[0002] The tobacco stalks are usually harvested after the tobacco leaves have matured. The specific time depends on the tobacco variety, the climate conditions of the growing area, and local agricultural practices. Generally speaking, the tobacco leaves are harvested in summer or autumn. When the color of the tobacco leaves changes from green to yellow or brown, it indicates that the tobacco leaves have matured and can be harvested.
[0003] During harvesting, it is difficult to completely dig out the tobacco stalks and roots from the soil. If the tobacco stalks and roots left in the soil are not removed in time, they will release heat during decomposition in the farmland. The high temperature will kill the beneficial microorganisms in the soil, causing a sharp decline in soil fertility and water retention capacity. In the long run, this will lead to soil diseases and pests, and the land will become barren, seriously affecting the growth of crops. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of rotary tiller blade that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model discloses a novel rotary tiller, which includes a rotating shaft. The rotating shaft is equipped with a tiller mechanism, which includes a support plate. The support plate comprises a first support plate and a second support plate, which are arranged parallel to each other on the rotating shaft. The first support plate is located on the axis of the rotating shaft, and the second support plate is located below the axis to the right of the first support plate. A blade is located between the ends of the first and second support plates.
[0006] As a preferred embodiment of this utility model, the first support plate and the second support plate have the same structure, and the first support plate and the second support plate are used to fix and support the blade.
[0007] As a preferred embodiment of this utility model, the first support plate and the second support plate are V-shaped plates, which tilt the blade at a certain angle and reduce the contact area between the blade and the soil.
[0008] As a preferred technical solution of this utility model, the first support plate and the second support plate are detachably connected to the blade by bolts. When the rotating shaft rotates, the blade will make a digging action, which can dig out the tobacco stem and its root from the soil. If the blade is damaged, it can be disassembled and replaced.
[0009] As a preferred embodiment of this utility model, there are multiple tillage blade mechanisms arranged on the rotating shaft, and the angles of two adjacent tillage blade mechanisms are different, so that the resistance on the rotating shaft is more uniform.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a first support plate and a second support plate arranged parallel to each other on a rotating shaft. The first support plate is located on the axis of the rotating shaft, and the second support plate is located below the axis to the right of the first support plate, so that the blade is in an inclined state. When inserted into the soil, the resistance can be reduced to the greatest extent. By inserting the blade into the soil at an incline, the rotating shaft continues to rotate, and the blade turns the soil upward, thus realizing the direct exposure of the tobacco stem root to the soil.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0016] like Figures 1 to 3 As shown, this utility model discloses a novel rotary tiller blade. The technical solution includes a rotating shaft 1, on which a tillering mechanism 2 is mounted. Multiple tillering mechanisms 2 are arranged in an array on the rotating shaft 1, with adjacent tillering mechanisms 2 having different angles. Figure 2 As shown, the tillage mechanism 2 includes a support plate, which includes a first support plate 3 and a second support plate 4. The first support plate 3 and the second support plate 4 have the same structure. The first support plate 3 and the second support plate 4 are V-shaped plates. The first support plate 3 and the second support plate 4 are arranged parallel to each other on the rotating shaft 1. The first support plate 3 is located on the axis of the rotating shaft 1, and the second support plate 4 is located below the axis to the right of the first support plate 3. The blade 5 is detachably connected to the first support plate 3 and the second support plate 4 by bolts.
[0017] The working principle of this utility model is as follows: When the rotating shaft 1 rotates clockwise, the tillage mechanism 2 will rotate synchronously. When the blade 5 comes into contact with the soil, the blade 5 is inserted into the soil at an angle. The rotating shaft 1 continues to rotate, and the blade 5 turns the soil up, thus directly turning the root of the tobacco stem out of the soil.
[0018] The circuits and mechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. They are common knowledge.
[0019] Components not described in detail in this article are existing technologies.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
