The deformable guide rail disclosed by the invention has the advantages that the outer wall is of a complete integrated structure, the inner wall is of an interval segmented structure, the rigidity of the inner wall is overcome, the guide rail can be deformed at different angles integrally, the deformable guide rail can be suitable for trunks with different thicknesses, and in actual use, the two ends of the deformable guide rail can be firmly fixed only by tightly binding the trunks with tightening belts or ropes. In addition, the sliding groove formed between the inner wall and the outer wall of the deformable guide rail and the outer teeth provide a foundation for hanging the agricultural machine on the guide rail and enabling the agricultural machine to do circular motion along the guide rail.

Description

Deformable guide rail

Technical Field

The invention relates to the field of agricultural machinery, in particular to a movable guide rail used for dragging an agricultural machine on a trunk.

Background

Some agricultural machines need to be fixed on a trunk during operation, for example, a rubber tapping machine needs to be fixed on a rubber tree, the rubber tapping machine disclosed in the chinese patent application CN104429813A has a fixed annular planetary gear housing, which cannot be adjusted according to the thickness and shape of the rubber trunk; the automatic rubber cutting robot disclosed in the chinese patent application CN106034980A utilizes a clamping mechanism composed of a rotating block and supporting rods, but obviously, the upper and lower circular rails and the motor, the trolley, the knife rest and other components erected on the circular rails cannot be firmly fixed on the trunk only by the tight contact area between the four supporting rods and the trunk, but the knife rest generates force during cutting, and the firmness is poor, so that the rubber cutting work is difficult to be completed in practice. Therefore, the invention provides a universal structure which can enable agricultural machinery to complete work on different trees and has firm and stable performance, which is a difficult problem in the field.

Disclosure of Invention

The invention aims to solve the technical problem of providing a deformable guide rail which can be adjusted according to the thickness and shape of a trunk and has good fixing performance.

In order to solve the technical problems, the invention adopts the following technical scheme:

in a deformable rail, the improvement comprising: the inner wall is of a spaced and segmented structure, the outer wall and each segment of the inner wall are connected into a whole, and a limiting sliding groove is formed between the inner wall and the outer wall.

Furthermore, a limit sliding groove is formed between the inner wall and the outer wall, and the upper part and the lower part of the limit sliding groove are respectively arranged.

Furthermore, the inner wall interval segmentation is equal-interval uniform segmentation or regular multiple small segments with equal intervals.

Further, the inner wall surface is a rough anti-slip surface.

Furthermore, the surface of the inner wall is provided with a convex nail.

Further, the shape of the convex nail is triangular, square conical, conical or hemispherical.

Furthermore, the deformable guide rail is made of ABS, PP-R, PP or PC.

The invention has the beneficial effects that:

the deformable guide rail disclosed by the invention has the advantages that the outer wall is of a complete integrated structure, the inner wall is of an interval segmented structure, the rigidity of the inner wall is overcome, the guide rail can be deformed at different angles integrally, the deformable guide rail can be suitable for trunks with different thicknesses, and in actual use, the two ends of the deformable guide rail can be firmly fixed only by tightly binding the trunks with tightening belts or ropes. In addition, the sliding groove formed between the inner wall and the outer wall of the deformable guide rail and the outer teeth provide a foundation for hanging the agricultural machine on the guide rail and enabling the agricultural machine to do circular motion along the guide rail.

The guide rail disclosed by the invention has the advantages that the inner wall of the guide rail is segmented at equal intervals or regularly divided into a plurality of small sections at equal intervals, so that the integral deformation of the guide rail is uniform. The inner wall of the guide rail is a rough anti-skid surface, which is mainly used for increasing the friction force between the guide rail and the trunk, and the convex nails are arranged to facilitate the guide rail to grasp the trunk surface.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Embodiment 1, as shown in fig. 1-2, this embodiment discloses a deformable guide rail, which is divided into an inner wall 2 and an outer wall 1, wherein teeth 3 capable of being matched with transmission are arranged on the outer side of the outer wall 1, the inner wall 2 is in a spaced and segmented structure, each segment of the outer wall 1 and each segment of the inner wall 2 are connected into a whole, and a limit sliding groove 4 is formed between the inner wall and the outer wall. The inner wall 2 is divided into completely equal-interval uniform sections or regular multiple small sections with equal intervals, for example, regular multiple sections with equal intervals such as two short sections and one long section, two short sections and two long sections, so that the guide rail arrangement deformation uniformity is facilitated by the divided sections. The surface of the inner wall 2 is a rough anti-skid surface, so that the friction force can be increased, for example, the inner wall is provided with wave or strip-shaped textures; the surface of the inner wall 2 can be also provided with a convex nail 5 to improve the capability of fastening and grabbing trees, the shape of the convex nail 5 can be triangular, square conical, conical or hemispherical and the like, and the convex nail 5 can be arranged on each section of the inner wall or only on some sections. The deformable guide rail disclosed in the embodiment is made of plastic materials, and can be ABS, PP-R, PP, PC or nylon and glass fiber.

Alternatively, in this embodiment, one stop slot is formed between the inner and outer walls.

When the agricultural machinery is used, the agricultural machinery is firstly hung on the deformable guide rail, and then the guide rail is hooped on the trunk and is tightly tied by a tightening belt or a rope.
