[0010] (1) The vertical rotary tillage device provided by this utility model for deeply burying straw in a field and homogenizing the soil layer utilizes crop straw from the same field as raw material, making use of waste and saving resources, and combines burying straw in the field with rotary tillage work. In addition, this utility model is equipped with a function to adjust the depth of rotary tillage, providing users with a more user-friendly and highly efficient rotary tillage component, making it convenient to operate and easy to popularize. When using the device, the user first attaches the device to a suitable traction device, that is, first connects it to the traction device via a hook, then connects the first transmission shaft to the output end of the traction device, and then the user can start deep tillage of the soil, that is, the first transmission shaft sequentially transmits power to the cutter rod, the cutter rod rotates and moves the cutter to perform rotary tillage of the soil.

[0011] (2) The vertical rotary tilling device has a simple principle and is convenient for attachment, detachment, and repair.

[Brief explanation of the drawing]

[0013] [Figure 1]This is a schematic diagram of the structure of the vertical rotary tillage device for deeply burying straw in a field and homogenizing the soil layer, as described in this utility model. [Modes for carrying out the invention]

[0014] The above description is merely an outline of the technical solution of this utility model. To better understand the technical solution of this utility model, it can be implemented according to the contents of the specification. In order to make the above and other objectives, features, and advantages of this utility model clearer and easier to understand, specific embodiments of this utility model are listed below.

[0015] Example 1 Referring to Figure 1, a vertical rotary tilling device for deeply burying straw in a field and homogeneously mixing the soil layer includes a mounting plate 17, bumps 18 and a support base 4, wherein the bumps 18 are fixedly connected to one end of the mounting plate 17, the bumps 18 and the support base 4 are movably hinged together by a plug 3, the support base 4 is provided with a plurality of movable hinge connection holes, a connecting rod 2 is fixedly connected to the side of the support base 4 away from the bumps 18, a hook 1 is fixedly connected to the end of the connecting rod 2 away from the support base 4, a roller assembly 13 is fixedly connected to the end of the mounting plate 17 away from the hook 1, a support column 8 is fixedly connected to the upper end of the mounting plate 17, a second transmission shaft 9 is provided on the support column 8, a universal joint 6 is connected to the end of the second transmission shaft 9 away from the mounting plate 17, and a first A transmission shaft 5 is connected, a first gear 10 is fixedly sleeve-connected to one end of the second transmission shaft 9 that is close to the mounting plate 17, a cutter rod 15 is rotatably inserted into the mounting plate 17, a second gear 11 is fixedly sleeve-connected to one end of the cutter rod 15 that is close to the second transmission shaft 9, the second gear 11 and the first gear 10 mesh with each other, a push plate 12 facing the mounting plate 17 is fixedly sleeve-connected to the cutter rod 15, a cutter 16 is connected to one end of the cutter rod 15 that is away from the second gear 11, a raw material box 7 is fixedly connected to one end of the mounting plate 17 that is close to the support base 4, the raw material box 7 extends through the mounting plate 17 in the direction of the cutter 16, a raw material discharge port is provided at the end of the raw material box 7 that extends in the direction of the cutter 16, and the direction of the raw material discharge port corresponds to the cutter 16.

[0016] In this embodiment, one end of the raw material box 7 that is close to the cutter 16 is funnel-shaped.

[0017] In this embodiment, the diameter of the second gear 11 is 2 to 5 times the diameter of the first gear 10.

[0018] In this embodiment, the diameter of the second gear 11 is three times the diameter of the first gear 10.

[0019] In this embodiment, an axial bearing 14 is installed between the push plate 12 and the mounting plate 17, with both end faces of the axial bearing 14 corresponding to the push plate 12 and the mounting plate 17, respectively.

[0020] The above technical solution involves making one end of the raw material box 7 adjacent to the cutter 16 funnel-shaped in order to limit the amount of straw discharged and to regulate the direction of straw discharge. The diameter of the second gear 11 is 2 to 5 times the diameter of the first gear 10, preferably 3 times in a preferred embodiment. Since the first gear 10 and the second gear 11 mesh with each other and have the same modulus of elasticity, the tooth ratio is equal to the ratio of their diameters. This pair of meshing gears not only plays a role in power transmission and changing the direction of power transmission, but also increases the deceleration torque because the ratio of the number of teeth of the second gear 11 to the number of teeth of the first gear 10 is 3, i.e., the transmission ratio is 3. In other words, by reducing the rotational speed of the rotary tillage cutter, the operating torque of the rotary tillage cutter is increased, ultimately ensuring sufficient soil cutting force and protecting the cutter to some extent. An axial bearing 14 is installed between the push plate 12 and the mounting plate 17, with both end faces of the axial bearing 14 corresponding to the push plate 12 and the mounting plate 17, respectively. The reason for this improvement is to ensure circumferential and axial positioning of the cutter rod, and the axial bearing 14 can share and receive the axial load.

[0021] The method for installing the vertical rotary tillage device provided by this utility model for deeply burying straw in a field and homogenizing the soil layer is as follows.

[0022] In step S1, a towing device suitable for the rotary tilling device is selected and connected to the towing device via hook 1. First, an appropriate towing machine is selected according to the specific situation, and then connected to the towing machine via hook 1 of this utility model.

[0023] In step S2, depending on the actual situation, an appropriate plug 3 is selected for the support base 4, the bump 18 and plug 3 are secured and fixed with a pin, and the bump 18 and plug 3 are connected with a pin to facilitate removal and reinstallation.

[0024] In step 3, the first transmission shaft 5 is connected to the output shaft of the traction device through a coupling. The coupling can perfectly connect the first transmission shaft 5 and the output shaft of the traction device and play a connecting role in power transmission.

[0025] In step S4, the raw material box 7 is filled with straw, the whole machine is turned on and moved to the place where work is required. After the cut straw is roughly divided, it is put into the raw material box 7 and then buried in the field through the rotary tillage device. At the same time, rotary tillage work is carried out, realizing the development of high-efficiency and sustainable environmentally friendly agriculture.

[0026] Here, the targets for field burying of straw are rice straw, sunflower straw, rapeseed straw, wheat straw, corn straw, etc. This utility model is mainly for fields where rice and tobacco leaves are alternately cultivated, to handle resources easily, utilize them efficiently and save costs. The main target for burying the straw in the field is rice straw.

[0027] The vertical rotary tillage device provided by this utility model for deeply burying straw in the field and homogenously mixing the soil layer is convenient to operate and has a simple principle. When a user uses the device, first, the device is attached to the traction device, that is, first connected to the traction device through the hook 1. Then, the first transmission shaft 5 is connected to the output end of the traction device. After that, the user can start deep tillage of the soil. That is, the first transmission shaft 5 sequentially transmits power to the cutter rod 15. The cutter rod 15 rotates to move the cutter 16 to perform rotary tillage of the soil. Furthermore, the user can add the already chopped straw to the raw material box 7, realizing the effect of burying the straw in the field while tilling. At the same time, since a plurality of movable hinge connection holes are provided on the support base 4, the user can adjust the inclination of the mounting plate 17 according to the depth of rotary tillage.
