Description

Technical Field

[0001] This utility model relates to the field of grass combing machine technology, and in particular to a protective structure for a grass combing machine and a grass combing machine. Background Technology

[0002] Lawn defoliators, as a type of garden maintenance equipment, are widely used in lawn grooming and thatch removal to promote healthy lawn growth. During operation, to improve versatility, the blades are often changed according to the specific task. When using the defoliator blades, they forcefully crush the lawn, breaking up dead grass, moss, and weeds, throwing them into a collection container at the discharge port. When using the loosening blades, a protective structure needs to be installed at the discharge port to prevent damage to operators and the surrounding environment from broken soil, flying stones, and other debris. Currently used protective structures are solid metal or plastic baffles, directly connected to the lawn defoliator housing via bolts arranged around the perimeter. While this allows for installation and disassembly, frequent bolt removal increases preparation time, and installation becomes impossible if the threaded holes of the bolts become stripped. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a protective structure for a grass comber and a grass comber. It solves the problems of frequent disassembly and assembly of the bolts of the protective structure in the existing grass comber, which increases the preparation time, and the inability to install after the threaded hole that mates with the bolt is stripped.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] This utility model embodiment proposes a protective structure for a hay comber, installed at the discharge port 504 of the housing 5, comprising:

[0026] The protective cover 1 has a mounting shaft extending along its width direction, and the protective cover 1 is rotatably mounted on the housing 5 via the mounting shaft;

[0027] The limiting component is detachably snapped onto the housing 5 and abuts against the protective cover 1, used to fix the protective cover 1 and open the discharge port 504, or to release the fixing of the protective cover 1 to close the discharge port 504.

[0028] In the embodiments of this utility model, such as Figure 3 As shown, the housing 5 has holes on both inner sides of the discharge port 504. The mounting shaft can be a shaft mechanism that passes through both ends of the protective cover 1, or it can be a shaft mechanism that is installed on both ends of the protective cover 1. When installing the protective cover 1, the mounting shaft can be directly installed into the hole opened in the housing 5 to complete the rotation installation of the protective cover 1.

[0029] In practical application, when using the combing tool to comb grass, the protective cover 1 can be directly lifted, allowing the protective cover 1 to rotate around the mounting shaft, thereby quickly opening the discharge port 504. Under the action of the limiting component, the protective cover 1 is limited, making it convenient to install a collection container to collect the dry grass. The collection container is generally a collection bag, which is installed in a set manner with the opening of the collection bag attached to the discharge port 504. The dry grass discharged through the discharge port 504 can directly enter the collection bag.

[0030] When using tools such as soil looseners, the limiting component releases the restriction on the protective cover 1, such as... Figure 4 As shown, the protective cover 1 can be rotated around the mounting shaft to fasten onto the discharge port 504, thus protecting the discharge port 504. Compared to traditional bolt fixing, this solution allows the discharge port 504 to be opened or closed simply by rotating the protective cover 1, making the operation very simple and quick. The aforementioned limiting component can be a screw or a pin structure, which can limit the movement of the protective cover 1 by abutting against it.

[0031] Based on the above solution, the structure of the limiting component is optimized, such as... Figure 1As shown, the limiting component is a limiting frame 2, which passes through the discharge port 504 and abuts against the protective cover 1. The limiting frame 2 is equipped with a mounting rod 202, and the housing 5 is equipped with a locking block 3. The mounting rod 202 is locked onto the locking block 3. The limiting frame 2 has a frame structure, and its mounting rod 202 can be directly locked onto the locking block 3. The locking block 3 supports the limiting frame 2, allowing it to abut against the protective cover 1, thus forming a stable support structure and preventing the protective cover 1 from closing on its own. Moreover, the top of the limiting frame 2 bends outward to form a mounting frame 201. The overall shape of the mounting frame 201 extends outward, which can better support the storage bag used to store straw.

[0032] Specifically, such as Figure 3 As shown, the inner side of the housing 5 is provided with a limiting edge 502 corresponding to the discharge port 504. The limiting frame 2 abuts against the limiting edge 502. The limiting edge 502 provides an axial support and positioning surface for the limiting frame 2, effectively preventing the limiting frame 2 from axially moving or accidentally coming out during use. The double constraint of the locking block 3 effectively enhances the overall structural rigidity and connection stability of the limiting frame 2.

[0033] Meanwhile, the bottom end of the limiting edge 502 extends along the opening direction of the discharge port 504 to form the mounting edge 503. As an extension structure, the mounting edge 503 enhances the overall rigidity of the limiting edge 502. During the installation process, it can also guide and position the limiting frame 2. In addition, it is convenient to install the collection bag with tools such as clamps.

[0034] Specifically, such as Figure 1 As shown, the inner side of the housing 5 is recessed along its thickness direction to form a storage groove 501. When the protective cover 1 closes the discharge port 504, the protective cover 1 is located in the storage groove 501. When the protective cover 1 is rotated to the position of closing the discharge port 504, it is embedded in the storage groove 501 on the inner side of the housing 5, which improves the neatness and overall appearance of the equipment.

[0035] Moreover, the side of the protective cover 1 is bent to form a connecting surface 102. The width of the connecting surface 102 corresponds to the width of the storage groove 501. Without increasing the thickness of the protective cover 1, the connection area between the protective cover 1 and the storage groove 501 is increased, which effectively ensures the tightness of the protective cover 1 in the storage groove 501.

[0036] Specifically, such as Figure 2As shown, the housing 5 is provided with a mounting base 4, and the inner side of the protective cover 1 is provided with a connecting block 101. A tension spring 401 is provided between the connecting block 101 and the mounting base 4. The tension spring 401 between the connecting block 101 and the mounting base 4 of the housing 5 provides a continuous restoring force for the protective cover 1. When the limit bracket 2 is removed, the spring force of the tension spring 401 will automatically drive the protective cover 1 to rotate around the mounting shaft, so that it can quickly and reliably close the discharge port 504 automatically, ensuring the stability of the protective cover 1 after it is fastened. In some other embodiments, a torsion spring can also be provided on the mounting shaft, and the torsional force can be used to apply a spring force to the protective cover 1, so that the protective cover 1 can quickly and reliably close the discharge port 504 automatically.

[0037] like Figure 1 As shown, this utility model embodiment also proposes a grass comber, including the above-mentioned protective structure for the grass comber. The specific structure of the protective structure is as described in the above embodiment. Since this grass comber adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
