Description

Technical Field

[0001] This utility model relates to the field of soil loosening machine technology, and in particular to a soil loosening machine. Background Technology

[0002] A soil tiller is an agricultural machine used to loosen soil. It includes a blade assembly that rotates to penetrate deep into the soil, effectively breaking up soil compaction and improving soil structure. As the machine moves forward, the blade assembly moves through the soil, loosening a certain area. This type of machine is widely used in farmland cultivation, orchard management, and landscaping, and can significantly improve soil aeration and water permeability, creating favorable conditions for crop root growth.

[0003] The blade assembly of a soil ripper is typically arranged laterally. As the machine moves forward, these components create a transverse loosening band in the soil. Therefore, the effective coverage area for each operation is the transverse width. For example, if the working width of the soil ripper is 1.5 meters, then each meter of forward movement loosens 1.5 square meters of soil. In agricultural machinery, similar parameters such as "tillage width" and "sowing width" refer to the transverse coverage area, which has become industry practice. Therefore, soil rippers use the term "working width." To ensure operational safety, soil rippers also include a safety plate, located above the blade assembly. Along the working width direction of the soil ripper, the safety plate's coverage area should cover the blade assembly. If the blade assembly extends beyond the safety plate's range, safety hazards may easily arise during operation, posing a direct threat to the operator's personal safety.

[0004] If the working width of the ripper needs to be extended due to operational requirements, the blade assembly needs to be extended accordingly, and the safety plate needs to be extended at the same time to ensure that the extended blade assembly is still within the safety protection range of the safety plate. However, directly extending the safety plate will increase the overall size of the equipment and the packaging volume, which will not only increase transportation costs, but also bring many inconveniences to the storage and handling of the equipment. Therefore, it is necessary to make improvements. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a soil loosening machine with a simple and reasonable structure and convenient operation. Through the detachable structural design, the second plate is designed as an independent addition. During transportation, the second plate can be separated from the equipment as a whole. Users can choose to expand the protection range of the mounting plate while keeping the packaging volume unchanged.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The present invention includes a frame, a blade assembly, and a safety plate. The blade assembly is detachably connected to the bottom of the frame. The safety plate is located above the blade assembly and is fixedly connected to the frame. The blade assembly includes a plurality of blades that extend along the working width direction of the ripper. Along the working width direction of the ripper, the blade assembly has a first end and a second end. At least the first end and the second end of the blade assembly are located within the edge contour of the safety plate. The safety plate includes a first plate, a second plate, and a connector. At least in the working width direction of the ripper, at least a portion of the edge contour of the second plate extends beyond the edge contour of the first plate. The second plate and the first plate are detachably fixedly connected by the connector.

[0007] Furthermore, the second plate includes a U-shaped opening, the second plate is connected to the outer edge of the first plate, and the first plate is located within the U-shaped opening.

[0008] Furthermore, the second plate includes a snap-fit ​​portion located at the edge of the second plate, through which the second plate engages with the first plate.

[0009] Furthermore, the snap-fit ​​portion extends downward from the lower surface of the second plate to form an extension section, the end of the extension section is bent inward to form a bent section, the extension section and the bent section are arranged in an "L" shape, and the first plate is placed on the upper surface of the bent section.

[0010] Furthermore, the connector is a knob, the lower end of which has a threaded section. The first plate has a first connecting hole that mates with the knob, and the second plate has a second connecting hole that mates with the knob. Both the first and second connecting holes are threaded holes, and the threaded section is threaded into the second connecting hole and the first connecting hole.

[0011] Furthermore, at least a portion of the outer edge of the first plate extends outward to form an extension plate, and the second plate is placed on the extension plate.

[0012] Furthermore, the thickness of the extension plate is less than the thickness of the first plate.

[0013] Furthermore, the lower surface of the second plate has a first rib, the inner sidewall of which abuts against the outer edge of the extension plate.

[0014] Furthermore, the upper surface of the second plate has a second rib, and a step is formed at the junction of the first plate and the extension plate, with the inner sidewall of the second rib abutting against the step.

[0015] Furthermore, there are several reinforcing ribs between the first rib and the outer edge of the second plate.

[0016] The beneficial effects of this utility model are as follows: The soil ripper of this utility model has a blade assembly detachably connected to the bottom of the frame, allowing for convenient and quick installation or replacement of blade assemblies of different specifications. A safety plate is located above the blade assembly and fixedly connected to the frame. The blade assembly has a first end and a second end along the working width direction of the soil ripper. At least the first and second ends of the blade assembly are located within the edge contour of the safety plate. The safety plate includes a first plate, a second plate, and a connecting member. The edge contour of the second plate extends beyond the edge contour of the first plate at least in the working width direction of the soil ripper. The second plate and the first plate are detachably connected by the connecting member. The fixed connection, through a detachable structural design, allows the second plate to be designed as an independent attachment. Users can decide whether to install the second plate according to actual operational needs. After installing the second plate, the protection range of the mounting plate is correspondingly expanded, allowing the blade assembly of the ripper to be extended accordingly, thereby increasing the working width of the ripper and improving operational efficiency. In addition, during transportation, the second plate can be separated from the equipment as a whole, avoiding the problem of increasing the overall size of the equipment caused by directly extending the safety plate, thus avoiding an increase in packaging volume. Users can selectively expand the protection range of the mounting plate to meet the personalized needs of different users while maintaining the same packaging volume. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-9 The soil ripper shown includes a frame 1, a blade assembly 2, and a safety plate 3. The blade assembly 2 is detachably connected to the bottom of the frame 1. Specifically, a housing 11 is provided on the frame 1. A motor and a clutch connected to the motor are installed in the housing 11. A reduction mechanism is also provided at the bottom of the frame 1. The input end of the reduction mechanism is connected to the clutch, and the output end of the reduction mechanism is connected to the blade assembly 2, driving the blade assembly 2 to rotate. The housing 11, motor, clutch, reduction mechanism, and blade assembly 2 are all prior art. Their structure / working principle can be referred to, for example, the multi-functional soil ripper disclosed in Chinese Patent (Announcement No.: CN104737645B), and therefore will not be described in detail here.

[0021] refer to Figure 1-5 The safety plate 3 is located above the blade assembly 2 and is fixedly connected to the frame 1. Specifically, the safety plate 3 is fixedly connected to the frame 1 by screws to ensure a stable and reliable connection that is not easily loosened. The blade assembly 2 includes a plurality of blades 21, which extend along the working width direction of the ripper. The blade assembly 2 has a first end 22 and a second end 23 along the working width direction of the ripper. At least the first end 22 and the second end 23 of the blade assembly 2 are located within the edge contour of the safety plate 3. It should be noted that the blade assembly 2 also has ends in other directions. In order to minimize potential safety hazards during operation, in this embodiment, all ends of the blade assembly 2 are covered by the safety plate 3. See reference. Figure 3 In the top view, the projected outline of the safety plate 3 completely covers the projected outline of the blade assembly 2.

[0022] In this embodiment, the blade assembly has two specifications, defined as a first blade assembly and a second blade assembly. Along the working width direction of the ripper, the length of the second blade assembly is greater than the length of the first blade assembly. To accommodate these two different specifications of blade assemblies 2, the safety plate 3 includes a first plate 31, a second plate 32, and a connector. (Refer to...) Figures 1-3 At least in the working width direction of the ripper, at least a portion of the edge contour of the second plate 32 extends beyond the edge contour of the first plate 31. Preferably, in this embodiment, referring to... Figure 6 and Figure 9 The second plate 32 includes a U-shaped opening 321. The second plate 32 is connected to the outer edge of the first plate 31, and the first plate 31 is located inside the U-shaped opening 321.

[0023] refer to Figure 6 Specifically, the second plate 32 is U-shaped and includes an inner edge contour and an outer edge contour. The edge of the U-shaped opening 321 is the inner edge contour of the second plate 32. The outer edge contour of the first plate 31 is defined as the first edge contour 313, the inner edge contour of the second plate is defined as the second edge contour 327, and the outer edge contour of the second plate is defined as the third edge contour 328. At least in the working width direction of the tiller, the third edge contour 328 extends beyond the first edge contour 313. In this embodiment, the third edge contour 328 also extends beyond the first edge contour 313 in the width direction of the safety plate 3.

[0024] refer to Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The second plate 32 is detachably fixed to the first plate 31 via the connector. The user can decide whether to install the second plate 32. When only the first blade assembly is used for operation, the basic configuration can be maintained, that is, the second plate 32 is not installed. When it is necessary to extend the working width of the ripper, the second plate 32 can be installed to expand the protection range of the safety plate 3 to adapt to the usage requirements of the second blade assembly, thereby improving the work efficiency. It should be noted that the first blade assembly can continue to be used after the second plate 32 is installed, but the second blade assembly is prohibited from being used without the second plate 32 installed, otherwise the second blade assembly will exceed the protection range of the safety plate 3, which will pose a safety hazard.

[0025] With its detachable structural design, the second plate 32 is designed as an independent addition. During transportation, the second plate 32 can be separated from the equipment as a whole, avoiding the problem of increasing the overall size of the equipment caused by directly extending the safety plate 3. This avoids increasing the packaging volume, and users can choose to expand the protection range of the mounting plate to meet the personalized needs of different users while keeping the packaging volume unchanged.

[0026] Preferably, in this embodiment, the reference Figures 4-5 The second plate 32 includes a snap-fit ​​portion 322, which is located at the edge of the second plate 32. The second plate 32 is snapped into the first plate 31 through the snap-fit ​​portion 322, which can effectively prevent loosening and make the connection between the second plate 32 and the first plate 31 more stable and reliable.

[0027] Preferably, in this embodiment, the reference Figures 4-5 The snap-fit ​​portion 322 extends downward from the lower surface of the second plate 32 to form an extension section 3221. The end of the extension section 3221 is bent inward to form a bent section 3222. The extension section 3221 and the bent section 3222 are arranged in an "L" shape. The first plate 31 is placed on the upper surface of the bent section 3222. The "L" shaped structural design can serve as a positioning reference. During the assembly process, it can help the operator quickly align the relative positions between the first plate 31 and the second plate 32, making it convenient and quick for the second plate 32 to be connected to the first plate 31. In addition, the "L" shaped structural design can also effectively play a limiting role, so that the second plate 32 is not easy to loosen after it is connected to the first plate 31.

[0028] Preferably, in this embodiment, the reference Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The connector is a knob 4, the lower end of which has a threaded section 41. The first plate 31 has a first connecting hole 3111 that mates with the knob 4, and the second plate 32 has a second connecting hole 323 that mates with the knob 4. Both the first connecting hole 3111 and the second connecting hole 323 are threaded holes. During installation, the second plate 32 is first aligned with the first plate 31 to ensure that the first connecting hole 3111 and the second connecting hole 323 are aligned. After alignment, the first connecting hole 3111 and the second connecting hole 323 are coaxially arranged. Then, the knob 4 is tightened so that the threaded section 41 is screwed into the second connecting hole 323 and the first connecting hole 3111 in sequence. The threaded connection between the threaded section 41 and the second connecting hole 323 and the first connecting hole 3111 is achieved, thus realizing a tight connection between the second plate 32 and the first plate 31. This not only ensures the stability of the connection but also facilitates subsequent disassembly.

[0029] Preferably, in this embodiment, the reference Figure 6 At least a portion of the outer edge of the first plate 31 extends outward to form an extension plate 311. The thickness of the extension plate 311 is less than the thickness of the first plate 31. The second plate 32 is placed on the extension plate 311. In this embodiment, the outer edge contour of the extension plate 311 is the first edge contour 313. Specifically, the first connecting hole 3111 is located on the extension plate 311, and the knob 4 is located on the extension plate 311. Since the thickness of the extension plate 311 is less than the thickness of the first plate 31, that is, the extension plate 311 and... There is a certain height difference between the first plate 31, so that a step portion 312 is formed at the junction of the first plate 31 and the extension plate 311. The step portion 312 can limit the second plate 32 and prevent the second plate 32 from sliding undesirably. In addition, the height difference design can also ensure that after the second plate 32 is connected to the first plate 31, the upper surface of the second plate 32 will not protrude too much from the upper surface of the first plate 31. Preferably, the upper surface of the second plate 32 is flush with the upper surface of the first plate 31, which is more aesthetically pleasing.

[0030] Preferably, in this embodiment, the reference Figures 8-9 The lower surface of the second plate 32 has a first rib 324. The first rib 324 is designed as a raised rib. The wall surface of the first rib 324 near the center of the extension plate 311 is the inner wall of the first rib 324. The inner wall of the first rib 324 abuts against the outer edge of the extension plate 311, which plays a limiting role and can effectively prevent the second plate 32 from shifting.

[0031] Preferably, in this embodiment, the reference Figures 6-8 The upper surface of the second plate 32 has a second rib 325, which is designed as a raised rib. A step portion 312 is formed at the junction of the first plate 31 and the extension plate 311. The wall surface of the second rib 325 near the center of the extension plate 311 is the inner wall of the second rib 325. The inner wall of the second rib 325 abuts against the step portion 312, which plays a limiting role and can effectively prevent the second plate 32 from shifting.

[0032] Preferably, in this embodiment, the reference Figure 9 The first rib 324 and the outer edge of the second plate 32 are further provided with several reinforcing ribs 326, which can effectively improve the overall strength and rigidity of the second plate 32 and prevent deformation during use.

[0033] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
