Description

Technical Field

[0001] This application relates to the field of micro-tiller accessories technology, and specifically discloses a trimming device for micro-tiller accessories. Background Technology

[0002] Mini tillers are powered by small diesel or gasoline engines and are characterized by their light weight, small size, and simple structure. They are widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. Equipped with appropriate implements, they can perform tasks such as pumping water, generating electricity, spraying pesticides, and watering. They can also tow trailers for short-distance transport. Mini tillers can move freely in the fields, making them convenient for users to operate and store. They eliminate the problem of large agricultural machinery being unable to access mountainous fields, making them the best alternative to oxen for farmers.

[0003] Most mini tillers have the following six functions: tilling, ridging, ditching, weeding, fertilizing, and harvesting. For harvesting, a harvesting blade is attached to the front of the mini tiller, which can also harvest crops.

[0004] For harvesting, there are currently blades related to mini-tiller accessories. The core of these blades is to cut the roots of crops as the mini-tiller moves, thus facilitating subsequent collection. However, the current problem is that if the crop roots are soft, the cutting effect will be very poor. Specifically, the driving force of the blades comes from the movement of the mini-tiller itself. To cut the crops, the crops need to have a certain resistance to the blades. Therefore, for soft crop roots, the sharp blades cannot effectively act on the roots after contact, resulting in missed cuts. This is unrelated to the speed of the mini-tiller or the sharpness of the blades. Therefore, missed cuts lead to repeated work or manual labor, increasing costs. In view of this, the inventor proposes a cutting device for mini-tiller accessories. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that traditional micro-tiller accessories have poor cutting effect when cutting softer crops.

[0006] To achieve the above objectives, the present invention provides the following basic solution:

[0007] A cutting device for a mini-tiller accessory includes a cutting component used in conjunction with the mini-tiller body. The cutting component is installed near the front of the mini-tiller body and close to the wheel. The cutting component is detachably connected to the mini-tiller body, and the height of the cutting component is higher than the height of the wheel.

[0008] The cutting assembly includes a housing, a bending assembly detachably connected to the housing for adjusting height and length, a secondary bending plate disposed on the housing on the same side as the bending assembly and at a lower height than the bending assembly, and a cutting blade disposed on the same side as the secondary bending plate and at a lower height than the secondary bending plate.

[0009] The principle and effect of this basic scheme are as follows:

[0010] 1. Compared with existing technologies, this device has a simple structure and ingenious design. This device is mainly used for cutting soft crop roots and stems. When such roots and stems are cut by the cutting blade, the blade cannot generate effective cutting force. By using a bending component, which is hung on the branches and leaves at the top of the crop, the crop is bent to a certain extent. Then, a secondary bending plate is used to make the crop roots and stems bend strongly. At this time, when the cutting blade is applied, the crop roots and stems can generate a strong reaction force, which is beneficial to the cutting blade. This ultimately solves the problem that traditional micro-tiller accessories have poor cutting effect when cutting softer crops.

[0011] 2. Compared with existing technologies, this device has virtually no possibility of missing cuts. The bending component can be adjusted in height and length. When installed on a mini-tiller, only minor adjustments are needed to apply it to the same crop area. The operation is relatively simple and convenient. Furthermore, the entire device is detachable, making it easy to install and disassemble when other accessories for the mini-tiller are needed.

[0012] 3. Compared with existing technologies, the core design of this device is simplicity. Unlike traditional blades, it does not require additional drive to rotate the blade, nor does it utilize the movement of the tiller to drive the blade's rotation. The above methods would make the structure too complex and have many vulnerable parts. Considering the users of tillers, this design directly addresses how to improve the support of soft roots and stems to achieve structural simplification, making the device suitable for tiller users. Although it does not have the self-rotation of a cutting blade, it is simpler in terms of size, structure, and usage. Subsequent maintenance and costs will be effectively controlled. For tiller users, the design of this device is essentially the best solution.

[0013] Furthermore, the housing is equipped with a connecting pipe, which is threadedly connected to the main body of the micro-tiller. This enables a detachable connection between the device and the micro-tiller body.

[0014] Furthermore, the bending assembly includes a main board and an inclined plate fixed to one end of the main board. The inclined plate has several snap-fit ​​slots, and the main board is slidably connected to the housing. This allows for bending of crop stems, which is beneficial for subsequent cutting.

[0015] Furthermore, the enclosure has several receiving slots arranged sequentially from top to bottom on the side near the motherboard. The side wall of the enclosure is provided with threaded holes, and screws are threaded into the threaded holes. The motherboard is inserted into the receiving slots and fixed by the screws.

[0016] Furthermore, the length of the secondary bending plate is longer than the length of the cutting blade. This ensures the bending effect of the secondary bending plate, thereby improving the cutting effect of the cutting blade.

[0017] Furthermore, the secondary bending plate has several grooves, and the cutting point of the cutting blade is at the lowest point of the groove.

[0018] Furthermore, a protective cutting plate is provided at the bottom of the housing. The protective cutting plate is lower than the height of the cutting blade. The protective cutting plate is L-shaped and has a sharp blade surface. The sharp blade surface is located at the outer end of the short side of the L-shaped protective cutting plate and is consistent with the cutting surface of the cutting blade. The protective cutting plate provides bottom protection. Attached Figure Description

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] Implementation, for example Figure 1 and Figure 2 As shown:

[0025] A cutting device for a mini-tiller accessory includes a cutting component used in conjunction with the mini-tiller body. The cutting component is installed near the front of the mini-tiller body and close to the wheel. The cutting component is detachably connected to the mini-tiller body, and the height of the cutting component is higher than the height of the wheel.

[0026] Regarding the tiller body, the tiller body adopts a push-type tiller, that is, a tiller with an engine, push rod, and wheels. Refer to Chinese Patent No. CN115868314B. The cutting component in this device is detachably connected to the tiller body. Specifically:

[0027] The cutting assembly includes a housing 1, a bending assembly 4 detachably connected to the housing 1 for adjusting height and length, a secondary bending plate 8 disposed on the housing 1 on the same side as the bending assembly 4 and at a lower height than the bending assembly 4, and a cutting blade 7 disposed on the same side as the secondary bending plate 8 and at a lower height than the secondary bending plate 8.

[0028] Specifically: The housing 1 is equipped with a connecting pipe 2, which is threadedly connected to the main body of the micro-tiller. This enables a detachable connection between the device and the micro-tiller body. Currently, most micro-tillers adopt a modular structure like the one in this case, meaning they have a main body and use different accessories to achieve personalized functions such as tilling, cutting, or ditching. Compared to traditional integrated micro-tillers, this has significant advantages in terms of cost, maintenance, and size.

[0029] like Figure 1 As shown, the bending assembly 4 includes a main board and an inclined plate fixed to the left end of the main board. The inclined plate has several snap-fit ​​slots 6. The main board is slidably connected to the housing 1. This allows for bending 12 of the stem of the crop 11, which is beneficial for subsequent cutting.

[0030] Regarding the height and length adjustment of the bending component 4, the side of the housing 1 near the main board has several receiving slots 5 arranged from top to bottom. The side wall of the housing 1 is provided with threaded holes, and screws 3 are threaded into the threaded holes. After the main board is inserted into the receiving slot 5, it is fixed by the screws 3.

[0031] The reason why the height and length of the bending component 4 need to be adjusted is that the height of different crops 11 and the bending angle required for bending 12 are different. In order to ensure the universality of this device, the bending component 4 is designed to be adjustable in both height and length.

[0032] like Figure 2As shown, when the snap-fit ​​groove 6 in the bending assembly 4 comes into contact with the branches and leaves of the crop 11, the branches and leaves are snapped in by the snap-fit ​​groove 6. As the micro-tiller continues to push, the rootstock below the branches and leaves begins to bend 12. The curvature of the bend 12 becomes more and more curved as the micro-tiller moves. However, the curvature at this time is a large bend, which is equivalent to a whole bend. At this time, the cutting bend acts on the bent rootstock, and the effect is not significant.

[0033] Therefore, a secondary bending plate 8 is provided. As the tiller continues to move, the secondary bending plate 8 also acts on the bent rootstock. Due to the influence of the secondary bending plate 8, the bent rootstock bends again, creating a strong bending point 13 at the contact point between the secondary bending plate 8 and the rootstock. Specifically, to refine this point, several grooves 9 are formed on the secondary bending plate 8. The cutting point of the cutting blade 7 is at the lowest point of the groove 9. Furthermore, to ensure the effectiveness of the cutting blade 7, the length of the secondary bending plate 8 is longer than the length of the cutting blade 7, ensuring the bending effect of the secondary bending plate 8.

[0034] As the mini-tiller moves, the cutting blade 7 acts on the strong bending point 13, which provides significant support to the soft rootstock. When the cutting blade 7 is applied, according to the principle of mutual force, the rootstock will be subjected to significant cutting force, thus eliminating the problem of the cutting blade 7 failing to cut effectively.

[0035] After the cutting blade 7 cuts off the strong bending point 13, the root and stem separate from the soil. When the upper locking groove 6 comes into contact with the branches and leaves of the crop 11, it is stuck at the position. Since the lower end no longer has a restraining force, as the micro-tiller continues to move, the locking groove 6 will separate from the branches and leaves and fall off.

[0036] Finally, a protective cutting plate 10 is provided at the bottom of the housing 1. The protective cutting plate 10 is lower than the height of the cutting blade 7. The protective cutting plate 10 is L-shaped and has a sharp blade surface. The sharp blade surface is located at the outer end of the short side of the L-shaped protective cutting plate 10 and is consistent with the cutting surface of the cutting blade 7. The protective cutting plate 10 provides bottom protection.

[0037] The significance of the protective cutting plate 10 is that when the height and length of the bending component 4 are not properly adjusted, the protective cutting plate 10 can provide a bottom protection for the cutting. The protective cutting plate 10 is designed to be closest to the soil. If the bending component 4 is not properly adjusted, the subsequent strong bending point 13 and the cutting blade 7 may have problems cooperating. Based on this, the protective cutting plate 10 is designed to ensure a certain cutting effect. Although there is still a problem that soft roots and stems cannot be cut, it ensures that the propulsion of this round of the mini-tiller is not useless.

[0038] Finally, this device needs to be tested before operation. The height and length of the bending component 4 should be adjusted reasonably and correctly so that the device can be applied to different crops.

[0039] This device solves the problem that traditional micro-tiller accessories have poor cutting effect when cutting softer crops 11.

Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
