Description

Technical Field

[0001] The utility model relates to the technical field of cotton pickers, in particular to a protective cover for a guardrail support of a cotton picker. Background Art

[0002] With the development of science and technology, agricultural machinery has gradually replaced manual labor and greatly improved productivity. As an automated machine for collecting cotton, cotton pickers have improved cotton picking efficiency and have been widely recognized and promoted.

[0003] At present, the guardrails and guardrail supports of the left and right corridors of the cotton picker are directly connected together with bolts. When the guardrails are folded during transportation and when the vehicle is driving, the guardrails collide and rub against the connected guardrail supports, which can easily scrape off the protective paint, causing the guardrail supports to rust due to the loss of protective paint, reducing their service life. In addition, unstable connections can easily cause the guardrails to fall off, resulting in the risk of people falling. Utility Model Content

[0004] In view of the fact that the protective paint falls off due to friction and collision between the guardrail support and the guardrail, thereby making the guardrail connection unstable and reducing the service life, the utility model proposes a cotton picker guardrail support protective cover to solve the above problem.

[0005] The technical solution of the utility model is as follows:

[0006] A protective cover for a cotton picker guardrail support, characterized in that it includes a guardrail, a base, a protective cover, a first nut, a first bolt, a guardrail support, a second nut, and a second bolt; the guardrail support is welded to the two ends of the outer side of the base; threaded holes are provided on both sides of the guardrail support; threaded holes equidistant from the upper threaded holes are provided in front of the lower threaded holes of the guardrail support; the protective cover is inserted into the bottom of the two ends of the guardrail and aligned with the threaded holes; the guardrail supports are inserted into the bottom of the two ends of the guardrail and the threaded holes are aligned, the upper threaded holes are connected by the first bolt and the first nut, and the lower threaded holes are connected by the second bolt and the second nut.

[0007] Furthermore, the guardrail is in the shape of a "sun", with the lower two ends extending downward for a certain length, and two upper and lower threaded holes are provided at the ends of both sides.

[0008] Furthermore, the guardrail is made of aluminum alloy.

[0009] Furthermore, the base is rectangular in shape.

[0010] Furthermore, the base is made of aluminum alloy.

[0011] Furthermore, a plurality of circular holes are provided on the surface of the base to prevent slipping.

[0012] Furthermore, the protective cover is in the shape of a cylindrical shell, with two sides being rectangular planes, and threaded holes are arranged on the upper and lower sides of the planes.

[0013] Furthermore, the protective cover is made of nylon.

[0014] Furthermore, the guardrail support is made of aluminum alloy.

[0015] Furthermore, when the guardrail is lowered, the first bolt and the first nut on the upper part are removed, the guardrail is flipped outward with the second bolt as the rotation axis, the threaded hole on the upper part of the guardrail is aligned with the threaded hole in front of the bottom of the guardrail support, and then fixed by the second bolt and the second nut.

[0016] Beneficial effects:

[0017] 1. The utility model adds a nylon protective cover at the connection between the guardrail and the support. When the guardrail is folded for transfer transportation, the softer nylon cover is in direct contact with the surface of the guardrail support, which prevents the paint of the guardrail support from being scratched and increases the service life of the guardrail base.

[0018] 2. The utility model increases the contact area between the guardrail and the support by adding a nylon protective cover at the connection between the guardrail and the support, increases the stability of the guardrail, and ensures the safety of the operators.

[0019] 3. The utility model adds a nylon protective cover at the connection between the guardrail and the support. Since the nylon protective cover is soft in texture, the noise generated by the collision and friction between the guardrail and the support is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following are specific embodiments, and in combination with the accompanying drawings, further describe the technical solution of the utility model. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] As Figure 1 、 2 shown, it is a schematic diagram of the installation of the protective sleeve 3 and a sectional view of the installation of the protective sleeve 3. It is characterized by including a guardrail 1, a base 2, a protective sleeve 3, a first nut 4, a first bolt 5, a guardrail support 6, a second nut 7, and a second bolt 8. The guardrail 1 is in the shape of a "day" character, and both lower ends of the guardrail 1 extend downward by a certain length, and there are two upper and lower threaded holes at both ends of the sides. The material of the guardrail 1 is aluminum alloy; the base 2 is rectangular in shape and the material is aluminum alloy. There are a plurality of round holes on the surface of the base 2 for anti-slip.

[0027] As Figure 3 、 4 shown, it is a schematic diagram of the structure of the protective sleeve 3 and a top view. The outer shape of the protective sleeve 3 is a cylindrical shell, and both sides are rectangular planes. Threaded holes are provided on both upper and lower sides of the plane. The material of the protective sleeve 3 is nylon material.

[0028] Weld the guardrail support 6 to both outer ends of the base 2; the guardrail support 6 is made of aluminum alloy; there are threaded holes on both upper and lower sides of the guardrail support 6, and there is a threaded hole equidistant from the upper threaded hole in front of the lower threaded hole; the protective sleeve 3 is sleeved on both ends of the bottom of the guardrail 1 and the threaded holes are aligned; both ends of the guardrail 1 are inserted into the guardrail support 6 and the threaded holes are aligned. The upper threaded hole is connected by the first bolt 5 and the first nut 4, and the lower threaded hole is connected by the second nut 7 and the second bolt 8.

[0029] When folding the guardrail 1, remove the upper first bolt 5 and the first nut 4, and the guardrail 1 is turned outwards with the second bolt 8 as the rotation axis; there is a threaded hole in front of the bottom of the guardrail support 6. When the guardrail 1 is reversed and lowered, the upper threaded hole of the guardrail 1 is aligned with the threaded hole in front of the bottom of the guardrail support 6, and then the guardrail 1 is fixed by the second bolt 8 and the second nut 7.

[0030] During the process of lowering the guardrail 1, since a protective sleeve 3 is installed between the guardrail 1 and the guardrail support 6, the friction between the guardrail 1 and the guardrail support 6 is isolated, preventing the paint of the guardrail support 6 from being scratched, and increasing the service life of the guardrail 1 and the guardrail support 6.
