Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts for windrowers, and in particular to a toothed guide rail type conveyor belt for windrowers. Background Art

[0002] At present, in order to ensure that the conveyor belt of the windrower can resist wear and damage during operation, the skeleton material used in the conveyor belt is relatively thick, resulting in poor flexibility of the conveyor belt during operation, which makes it easy for stress concentration to occur on the conveyor belt under the action of external force. Long-term stress concentration will cause local deformation and damage of the conveyor belt, accelerate the aging of the conveyor belt, and affect the service life of the conveyor belt. Utility Model Content

[0003] The utility model provides a toothed rail type windrower conveyor belt, which solves the problem in the related art that the conveyor belt has a short service life due to thick frame materials.

[0004] The technical solution of the utility model is as follows:

[0005] A toothed rail type windrower conveyor belt comprises a belt body, on which a plurality of rail strips for matching rail grooves are arranged, each of which comprises a support body and a sliding sleeve strip, wherein the support body is located in the sliding sleeve strip and is fixedly connected to the belt body, and the sliding sleeve strip is detachably connected to the support body.

[0006] Furthermore, the longitudinal section of the sliding sleeve is an inverted "U"-shaped structure.

[0007] Furthermore, abutment plates are provided on both sides of the sliding sleeve, each of the abutment plates abuts against the belt body, and each of the abutment plates is symmetrically distributed with the sliding sleeve as the center.

[0008] Furthermore, both sides of the support body are provided with engaging grooves, and one end of the abutment plate close to the support body is slidably connected to the engaging groove.

[0009] Furthermore, the sliding sleeve strip is provided with a plurality of sliding components, and the sliding components are arranged in sequence along the axial direction of the sliding sleeve strip.

[0010] Furthermore, each of the sliding components includes a plurality of balls, each of the balls is evenly distributed along the outer surface of the sliding sleeve, and each of the balls is rotatably connected to the sliding sleeve.

[0011] Furthermore, the outer surface of the sliding sleeve is provided with a wear-resistant coating.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. The belt body of the utility model is provided with a guide rail, which is slidably connected with the guide rail groove on the windrower, and an additional constraint and friction force are introduced at the connection part, so that the connection between the two has higher rigidity and is more reliable. This additional rigidity can effectively transmit the load and bear the effect of external force, reduce the deformation and bending of the overall structure of the belt body when it is subjected to external force, and increase the service life of the belt body.

[0014] 2. The guide rail in the utility model includes a support body and a sliding sleeve. The sliding sleeve is a guide rail component that contacts the guide rail groove. The sliding sleeve will produce a certain amount of wear due to friction during operation. Therefore, the sliding sleeve can be detachably connected to the support body, which is convenient for replacing the sliding sleeve when it is worn. Compared with replacing the entire guide rail or the entire belt body, replacing only a small part (the sliding sleeve) is more economical. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-2 As shown, the present embodiment proposes a toothed guide rail type windrower conveyor belt, which mainly includes a belt body 1, and the belt body 1 should preferably be composed of a flex-resistant rubber canvas base belt, because the flex-resistant rubber canvas base belt is usually made of high-strength material, has good wear resistance and durability, can withstand frequent flexing and stretching and is not easily damaged; and a rubber strip edge 4 is provided on the belt body 1, and the rubber strip edge 4 itself usually has a certain elasticity and flexibility, and can be deformed evenly when subjected to force, and can effectively limit the deformation range of the flex-resistant rubber canvas base belt after cooperating with the flex-resistant rubber canvas base belt, prevent the flex-resistant rubber canvas base belt from generating a large deformation during operation, and avoid deformation fatigue of the belt body 1, resulting in poor flexibility.

[0025] like Figure 5 As shown, a plurality of guide rails 2 for cooperating with the guide rail grooves 5 are provided on one end of the belt body 1 away from the rubber strip edge 4 in this embodiment. The guide rails 2 are slidably connected with the guide rail grooves 5 to introduce additional constraints and friction between the belt body 1 and the windrower body, so that the connection is more firm and the connection is more rigid, so that the load can be effectively transmitted and external forces can be borne, thereby reducing the bending of the belt body 1 and improving the bending resistance of the belt body 1; and the guide rails 2 are slidably connected with the guide rail grooves 5, which can limit the freedom of relative displacement of the connecting parts, inhibit the deformation of the belt body 1 to a certain extent, thereby reducing the bending of the belt body 1 and improving the bending resistance of the belt body 1.

[0026] Each guide rail 2 includes a support body 21 and a sliding sleeve 22. The support body 21 is located in the sliding sleeve 22 and is fixedly connected to the belt body 1. Because the support body 21 mainly plays the role of supporting the sliding sleeve 22, in order to ensure the stability of the structure between the support body and the belt body 1, the fixed connection method between the support body 21 and the belt body 1 is preferably that the support body 21 and the belt body 1 are integrally formed to prevent the support body 21 from detaching from the belt body 1 when the belt body 1 is deformed, thereby fully ensuring the stability of the overall structure of this embodiment.

[0027] And because the sliding sleeve 22 is a component in contact with the guide rail groove 5, when the belt body 1 is used for conveying, in order to ensure the connection relationship between the guide rail 2 and the guide rail groove 5, the sliding sleeve 22 will inevitably rub against the guide rail groove 5, and under the action of friction, the sliding sleeve 22 is easily worn; therefore, the sliding sleeve 22 is detachably connected to the support body 21, so that the sliding sleeve 22 can be replaced when it is worn; and compared with the replacement and scrapping of the entire belt body 1 due to wear, if only one sliding sleeve 22 is replaced, its replacement cost is significantly lower, which effectively reduces the maintenance cost of the conveyor belt of the windrower.

[0028] The sliding sleeve 22 in this embodiment is preferably made of a flexible plastic material such as polyethylene, so that the sliding sleeve 22 can be deformed in coordination with the belt body 1 during the installation of the belt body 1.

[0029] At the same time, the outer surface of the sliding sleeve 22 is provided with a wear-resistant coating 3, which effectively reduces the friction and wear between the sliding sleeve 22 and the guide rail groove 5, protects the surface of the sliding sleeve 22 from wear, and increases the service life of the sliding sleeve 22.

[0030] like Figure 2 to Figure 4 As shown, the longitudinal section of the sliding sleeve 22 in this embodiment is an inverted "U"-shaped structure. Since the "U"-shaped structure has a certain curvature, it can effectively withstand the loads in the horizontal and vertical directions and has a high bearing capacity. When the belt body 1 is driven by force to move the sliding sleeve 22 in the direction of the guide groove 5, the high bearing capacity of the "U"-shaped structure can be used to resist the impact force caused by the movement, thereby ensuring the stability of the operation of this embodiment.

[0031] Both sides of the sliding sleeve 22 are provided with abutment plates 221, and each abutment plate 221 is integrally formed with the sliding sleeve 22, which fully ensures the stability of the connection between the abutment plate 221 and the sliding sleeve 22; each abutment plate 221 abuts against the belt body 1, so that the sliding sleeve 22 has a support point on the belt body 1. When the sliding sleeve 22 is impacted or vibrates due to friction with the guide rail groove 5, the force can be transmitted to the belt body 1 through the abutment plate 221, and the force is dispersed, thereby avoiding these forces from being continuously The abutment plates 221 are symmetrically distributed around the sliding sleeve 22 to ensure that the force on the sliding sleeve 22 is evenly dispersed and that the belt body 1 is in a relatively balanced state when bearing the force brought by the sliding sleeve 22, thereby achieving force balance and avoiding the belt body 1 from experiencing a stress concentration state after the force on the sliding sleeve 22 is transmitted to the belt body 1.

[0032] Both sides of the support body 21 are provided with an embedding groove 211, and one end of the abutment plate 221 close to the support body 21 is slidably connected to the embedding groove 211. This connection method can use the embedding groove 211 to constrain the sliding sleeve 22 in the vertical direction of the horizontal plane in the initial installation stage, thereby preventing the belt body 1 from detaching from the belt body 1 when the belt bodies 1 are connected end to end to form an endless conveyor belt, thereby ensuring the stability of the overall structure of this embodiment.

[0033] like Figure 3-4As shown, the sliding sleeve 22 in this embodiment is provided with a plurality of sliding components 23, and each sliding component 23 is located between the sliding sleeve 22 and the guide rail groove 5, that is, the sliding components 23 are used to reduce the friction and resistance between the sliding sleeve 22 and the guide rail groove 5, so as to avoid the sliding sleeve 22 from getting stuck or blocked during the sliding process, thereby improving the sliding performance of the sliding sleeve 22 and extending the service life of the sliding sleeve 22; at the same time, each sliding component 23 is arranged in sequence along the axial direction of the sliding sleeve 22, so that the spacing between adjacent sliding components 23 is close to the same, ensuring that the sliding sleeve 22 can slide smoothly in the guide rail groove 5.

[0034] Each sliding assembly 23 in the present embodiment includes a plurality of balls 231, and each ball 231 is rotatably connected to the sliding sleeve 22, that is, the sliding sleeve 22 is slidably connected to the guide groove 5 by means of the rotation of the ball 231, and the ball 231 is spherical in structure as a whole, that is, when the ball 231 is subjected to external force and pressure, it can achieve uniform force by means of the characteristics of the spherical structure; and it can effectively withstand forces from all directions to maintain the stability of the overall structure; that is, it meets the requirement that the sliding sleeve 22 does not directly contact the guide groove 5, and when the belt body 1 is subjected to force to drive the sliding sleeve 22 to move in the direction of the guide groove 5, it can replace the sliding sleeve 22 with a "U"-shaped structure to resist the impact force caused by the movement of the belt body 1, thus killing two birds with one stone. The balls 231 are evenly distributed along the outer surface of the sliding sleeve 22 , so that there are balls 231 between each surface of the sliding sleeve 22 and each surface of the guide rail groove 5 , fully ensuring that the force range of the balls 231 can cover the outer surface of the sliding sleeve 22 .

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
