Description

Technical Field

[0001] This utility model relates to the field of snowplow head technology, and in particular to a snowplow head component with protective function. Background Technology

[0002] Every winter there is a lot of snowfall. In the process of landscaping, some plants are not resistant to low temperatures. If they are covered with snow for a long time, they are prone to die in the low temperature environment. Therefore, after snowfall, it is necessary to remove the snow covering the plants. Snow shovel heads are one of the most important components in the process of snow removal in landscaping. Compared with manual snow shoveling, snow shovel heads are more efficient and easier to use.

[0003] However, the existing snowplow heads have certain shortcomings:

[0004] Since the snowplow head needs to transmit power through the transmission shaft when it is working, if it is affected by external forces during the working process, such as collisions, the transmission part of the snowplow head is prone to displacement, which can cause the transmission parts to deform and thus affect the normal operation of the snowplow head.

[0005] Secondly, the transmission components of existing snowplows are usually integrated structures, which require disassembly and replacement if damaged, making them inconvenient to use. Summary of the Invention

[0006] The purpose of this application is to provide a snowplow head assembly with protective function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a snowplow head assembly with protective function, comprising a frame, the frame including a chassis, an installation groove formed on the outer wall of the chassis, the installation groove being circular, an installation shaft rotatably mounted on the inner wall of the installation groove, the installation shaft being adapted to the installation groove, a limiting ring provided on the inner wall of the installation groove, the limiting ring being adapted to the installation groove, the installation shaft being rotatably connected to the inner wall of the limiting ring, fixing rods evenly distributed on the outer wall of the limiting ring, the ends of the fixing rods being connected to the inner wall of the installation groove, and an installation cylinder provided on one side of the outer wall of the chassis, the installation cylinder being inclined and adapted to the installation groove.

[0008] Preferably, the chassis is provided with support frames on all four sides of the outer wall away from the mounting cylinder, and a support seat is provided on the top outer wall of the support frame. The support seat is cylindrical and is adapted to the support frame.

[0009] Preferably, a protective pad is provided on the top outer wall of the support base, the protective pad is adapted to the support base, and the thickness of the protective pad is less than the thickness of the support base.

[0010] Preferably, a drive shaft is fixedly connected to the end of the mounting shaft, the mounting shaft and the drive shaft are adapted to each other, the mounting shaft and the drive shaft have the same diameter, and the end of the drive shaft is provided with a threaded groove.

[0011] Preferably, a connecting pin is provided on the outer wall of the mounting shaft near the drive shaft, and a connecting hole is provided on the outer wall of the drive shaft near the mounting shaft. The connecting pin is adapted to the connecting hole, and the diameter of the connecting pin is smaller than the diameter of the drive shaft and the mounting shaft.

[0012] Preferably, the inner wall of the connecting hole is provided with an anti-slip sleeve, which is adapted to the connecting hole. The outer wall of the connecting pin and the inner wall of the connecting hole are provided with equally spaced fixing holes. The end of the drive shaft near the mounting shaft is provided with equally spaced mounting bolts, which are connected to the fixing holes by thread rotation.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, during operation, the mounting shaft rotates continuously under the drive of the driving component. At this time, the limiting ring restricts the mounting shaft, so that the mounting shaft is always within the fixed range of the limiting ring, maintaining the stable rotation of the mounting shaft and preventing it from being deviated by external forces, thus avoiding transmission damage. Compared with traditional devices, by protecting the mounting shaft with the limiting ring, the rotation of the mounting shaft is more stable and less prone to deviation, preventing the mounting shaft from being damaged by the force of deviation.

[0015] In this invention, the protective pad on the support base protects the support base and reduces wear during operation. At the same time, the rubber protective pad makes the connection of the support base more stable and less prone to loosening.

[0016] In this invention, the drive shaft and the mounting shaft are connected by a connecting pin and a connecting hole. When the outer wall of the drive shaft wears down due to long-term operation, it is only necessary to separate the drive shaft from the mounting shaft and replace the drive shaft. The operation is simple and the use is more convenient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figure 1-4 The snowplow head assembly with protective function shown includes a frame 1, which includes a chassis 2. The outer wall of the chassis 2 has a mounting groove 3, which is circular. A mounting shaft 4 is rotatably mounted on the inner wall of the mounting groove 3 and is adapted to the mounting groove 3. A limiting ring 5 is provided on the inner wall of the mounting groove 3 and is adapted to the mounting groove 3. The mounting shaft 4 is rotatably connected to the inner wall of the limiting ring 5. Fixed rods are provided on the outer wall of the limiting ring 5 at equal intervals and the ends of the fixed rods are connected to the inner wall of the mounting groove 3. A mounting cylinder 6 is provided on one side of the outer wall of the chassis 2. The mounting cylinder 6 is inclined and is adapted to the mounting groove 3.

[0025] With the above structure: during operation, the mounting shaft 4 rotates continuously under the drive of the drive component. At this time, the limiting ring 5 restricts the mounting shaft 4, so that the mounting shaft 4 is always within the fixed range of the limiting ring 5, maintaining the stable rotation of the mounting shaft 4 and preventing it from being deviated by external forces, thus avoiding transmission damage. Compared with traditional devices, by protecting the mounting shaft 4 with the limiting ring 5, the rotation of the mounting shaft 4 is more stable and less prone to deviation, preventing the mounting shaft 4 from being damaged by the force of deviation.

[0026] like Figure 1As shown, support frames 7 are provided on all four sides of the outer wall of the chassis 2 away from the mounting cylinder 6. Support seats 9 are provided on the top outer wall of the support frames 7. The support seats 9 are cylindrical and are adapted to the support frames 7. Protective pads 10 are provided on the top outer wall of the support seats 9. The protective pads 10 are adapted to the support seats 9. The thickness of the protective pads 10 is less than the thickness of the support seats 9. The protective pads 10 on the support seats 9 protect the support seats 9 and reduce the wear of the support seats 9 during operation. At the same time, the rubber material of the protective pads 10 makes the connection of the support seats 9 more stable and less prone to loosening.

[0027] like Figure 3 As shown, a drive shaft 8 is fixedly connected to the end of the mounting shaft 4. The mounting shaft 4 and the drive shaft 8 are compatible and have the same diameter. The drive shaft 8 has a threaded groove 11 at its end. A connecting pin 12 is provided on the outer wall of the mounting shaft 4 near the drive shaft 8. A connecting hole 13 is provided on the outer wall of the drive shaft 8 near the mounting shaft 4. The connecting pin 12 is compatible with the connecting hole 13. The diameter of the connecting pin 12 is smaller than the diameter of the drive shaft 8 and the mounting shaft 4. An anti-slip sleeve 14 is provided on the inner wall of the connecting hole 13. The anti-slip sleeve 14 and the connecting hole... The drive shaft 8 is fitted with 13 pairs of connecting pins. The outer wall of the connecting pin 12 and the inner wall of the connecting hole 13 are provided with equally spaced fixing holes 15. The drive shaft 8 is provided with equally spaced mounting bolts 16 near the mounting shaft 4. The mounting bolts 16 and the fixing holes 15 are connected by threads. The drive shaft 8 and the mounting shaft 4 are connected by the connecting pin 12 and the connecting hole 13. When the outer wall of the drive shaft 8 is worn due to long-term operation, it is only necessary to separate the drive shaft 8 from the mounting shaft 4 and replace the drive shaft 8. The operation is simple and the use is more convenient.

[0028] The working principle of this practical application is as follows:

[0029] During operation, the mounting shaft 4 rotates continuously under the drive of the drive component. At this time, the limiting ring 5 restricts the mounting shaft 4, so that the mounting shaft 4 is always within the fixed range of the limiting ring 5, maintaining the stable rotation of the mounting shaft 4 and preventing it from being deviated by external forces, thus avoiding damage to the transmission. Compared with traditional devices, by protecting the mounting shaft 4 with the limiting ring 5, the rotation of the mounting shaft 4 is more stable and less prone to deviation, preventing the mounting shaft 4 from being damaged by the force of deviation.

[0030] The protective pad 10 on the support base 9 protects the support base 9 and reduces the wear of the support base 9 during operation. At the same time, the rubber protective pad 10 makes the connection of the support base 9 more stable and less prone to loosening.

[0031] The drive shaft 8 and the mounting shaft 4 are connected by the connecting pin 12 and the connecting hole 13. When the outer wall of the drive shaft 8 is worn due to long-term operation, it is only necessary to separate the drive shaft 8 from the mounting shaft 4 and replace the drive shaft 8. The operation is simple and the use is more convenient.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
