Description

Technical Field

[0001] The utility model relates to the field of corn planting, and more specifically, to a corn planting land tilling device. Background Technique

[0002] In current agricultural mechanized operations, land tillage before corn planting is a key link to ensure the crop growth environment and improve soil air permeability and water retention capacity. Traditional tilling devices often adopt an integral tilling roller design, where the tilling plates are directly welded or fixed to the roller body. Although this design has a relatively simple structure, there are many inconveniences in actual use. First, due to the complex and changeable field operation environment, the tilling plates are easily damaged due to collision and wear. Once damaged, the entire tilling roller assembly needs to be returned to the factory for repair or replacement, which is time-consuming, laborious and costly. Second, different plots have different requirements for tilling depth and width, while the length of the tilling plates of traditional devices is fixed, making it difficult to meet diverse tilling needs and restricting the flexibility and adaptability of the devices.

Specific embodiments

[0020] To make the purposes, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a corn - planting soil - turning device, including an N - type mounting frame 1. Between the inner walls on both sides of the N - type mounting frame 1, a number of soil - turning roller assemblies 2 evenly distributed in a horizontal straight line are rotatably installed. On one side surface of the N - type mounting frame 1, a traction part 3 is provided. Each soil - turning roller assembly 2 includes a roller body 201. On the surfaces at both ends of the roller body 201, connecting shafts 202 are integrally provided. One end of each connecting shaft 202 is rotatably connected to the corresponding inner wall on one side of the N - type mounting frame 1. On the outer wall of the circumference of the roller body 201, a number of mounting grooves 203 evenly distributed in a ring are provided. In each mounting groove 203, a mounting plate 204 is slidably installed. On one side surface of each mounting plate 204, a number of evenly distributed soil - turning plates 205 are integrally provided. On one end surface of the roller body 201, an unlocking and limiting mechanism for limiting a number of mounting plates 204 is also provided.

[0022] Please refer to Figures 3 to 5 , one end of each mounting groove 203 penetrates through one end face of the roller body 201. On one end surface of each mounting plate 204, a pin seat 206 is integrally provided. One end of a pin rod 207 is inserted into each pin seat 206. On one side surface of each pin rod 207, a slide bar 210 is integrally provided. Each slide bar 210 is slidably installed in the corresponding linear chute 211. A number of linear chutes 211 are evenly distributed in a ring coaxial with the roller body 201 and provided on one end face of the roller body 201. The other end of each pin rod 207 is connected to the unlocking and limiting mechanism.

[0023] When in use, the mounting plate 204 is inserted through the through-opening of the mounting groove 203 until one end of the mounting plate 204 abuts against the inner wall of one end of the mounting groove 203. After the mounting plate 204 is installed in place, the pin rod 207 can be driven to slide toward the pin seat 206 by unlocking the limiting mechanism until one end of the pin rod 207 is plugged into the pin seat 206, thereby completing the limitation of the mounting plate 204 and ensuring that the mounting plate 204 will not fall out of the through-opening of the mounting groove 203, thereby improving stability during use.

[0024] Furthermore, connecting grooves 208 are provided on both side surfaces of each mounting plate 204 , and a limiting guide rod 209 is slidably connected in each connecting groove 208 . The two limiting guide rods 209 are integrally arranged on the inner walls on both sides of the corresponding mounting groove 203 .

[0025] The mounting plate 204 is slidably connected to the mounting groove 203 through the cooperation of the limiting guide rod 209 and the connecting slide groove 208, and the mounting plate 204 is further limited. When the roller body 201 rolls as a whole, the mounting plate 204 will not fall out along the radial direction of the roller body 201.

[0026] Furthermore, the unlocking and limiting mechanism includes a driving ring 212, on the surface of one side of which an annular slider 213 is coaxially arranged, and the annular slider 213 is slidably connected to the annular groove 214. The annular groove 214 is opened on the surface of one end of the roller body 201 and is coaxially arranged with the roller body 201. On the surface of the other side of the driving ring 212, one end of a plurality of connecting rods 216 that are consistent with the pin rod 207 are rotatably connected, and the other end of each connecting rod 216 is rotatably connected to one end of the pin rod 207. A torsion spring 215 is connected between the inner wall of the driving ring 212 and the outer wall of the corresponding side connecting shaft 202.

[0027] In the normal state, under the restriction of the torsion spring 215, the overall angular position of the drive ring 212 remains relatively stable. At this time, the position of the pin rod 207 remains in the plug-in state with the pin seat 206. When the mounting plate 204 needs to be removed for replacement or maintenance, the drive ring 212 can be rotated to change its angle. When the drive ring 212 rotates, it drives one end of all the connecting rods 216 to rotate, thereby pulling all the pin rods 207 toward the axial direction of the roller body 201 through several connecting rods 216, so that the pin rods 207 are disengaged from the pin seat 206, and the mounting plate 204 can be pulled out of the mounting groove 203. After loosening the drive ring 212, the angle of the drive ring 212 is reset under the action of the torsion spring 215, thereby driving all the pin rods 207 to return to the initial position.

[0028] Furthermore, the roller body 201 is a solid structure.

[0029] By setting the roller body 201 as a solid structure to increase its own weight, when plowing the land with the traction of a traction device, the self-weight of the roller body 201 is used to insert the soil turning plate 205 into the soil for turning, thereby improving the plowing efficiency.

[0030] Furthermore, an anti-corrosion coating is provided on the outer part of the roller body 201.

[0031] By providing a corrosion-resistant coating on the outer wall of the roller body 201, its service life can be extended, and the use loss and maintenance cost can be reduced.

[0032] Please refer to Figure 2 , the traction part 3 includes a connecting part 301 integrally provided on one surface of the N-shaped mounting frame 1. One end of the connecting part 301 is rotatably connected to one end of the connecting rod 302. The other end of the connecting rod 302 is rotatably connected to one end of the pull rod 303. A pull ring 304 is integrally provided at the other end of the pull rod 303.

[0033] The connecting rod 302 is used to connect the pull rod 303 and the connecting part 301, and the connecting directions of both ends of the connecting rod 302 are vertically arranged, so as to facilitate turning when the traction device pulls the whole and adjust the height of the position where the pull ring 304 is connected to the traction device.

[0034] Working principle: The whole is connected to a traction device such as a tractor or an ox through the traction part 3. The whole is pulled by the traction device or the ox, so that several plowing roller assemblies 2 can roll forward on the land, and the soil is turned by the soil turning plate 205. When the soil turning plate 205 provided on the surface of a certain mounting plate 204 is damaged or the length of the soil turning plate 205 does not meet the planting requirements and the specific conditions of the soil, the corresponding drive ring 212 can be rotated to make the drive ring 212 drive all the corresponding pin rods 207 to slide in the direction of the axis of the roller body 201 and disengage from the clamping with the pin seats 206, so as to release the limit on the mounting plate 204. Then the mounting plate 204 can be taken out from the corresponding mounting groove 203, repaired and replaced with a new mounting plate 204 and reinstalled. Finally, the mounting plate 204 is limited again through the unlocking limit mechanism. By modularly separating the roller body 201 and the mounting plate 204, it is convenient to disassemble the mounting plate 204 and the soil turning plate 205, thereby improving the convenience during use and reducing the use and maintenance costs.

[0035] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
