Description

Technical Field

[0001] This utility model relates to the field of agricultural and livestock machinery technology, and is an improvement of the guide rope sleeve structure for balers, specifically an improved guide rope sleeve for balers. Background Technology

[0002] my country has a wide variety of agricultural and livestock machinery, among which balers are widely used. The main working process of a baler is to wrap already compressed materials with baling rope and then tie them with a knotter for further fixation. The main function of the guide rope sleeve is to guide the baling rope along a set path, preventing the baling rope from becoming tangled and causing the baler to malfunction. Due to prolonged friction with the baling rope, the contact area between the guide rope sleeve's threading hole and the baling rope often wears down, leading to uneven rope passage, wear on the baling rope, and resulting in untidy bales, reducing the baler's baling rate. Currently, baler guide rope sleeves on the market only have one positioning surface, requiring the entire guide rope sleeve to be replaced after wear, resulting in a relatively short service life and wasted resources. Utility Model Content

[0003] The purpose of this utility model is to provide an improved guide rope sleeve for a baler, which has a reasonable structure, can extend service life, improve work efficiency, and has low operating costs.

[0004] The purpose of this utility model is achieved as follows: an improved guide rope sleeve for a baler, comprising a guide rope sleeve through which baling rope is threaded when the hay baler is baling hay. The guide rope sleeve has a through hole at the center of a cylinder, and symmetrical discs at both ends of the cylinder. Evenly distributed arc-shaped guide rope grooves are provided on the circumference of the discs. The guide rope grooves cooperate with the baling rope. A transition arc surface is provided at the junction of the outer end of the through hole and the surface of the disc. The diameter of the through hole is larger than the diameter of the baling rope.

[0005] This invention features multiple positioning surfaces, i.e., rope guide grooves. The rope guide sleeve for the baler is shaped like a dumbbell, with a cylinder in the middle and identical, symmetrical polygonal cylindrical disks at both ends. Each plane along the circumference of the disk has a rope guide groove that can serve as a positioning surface. This invention employs a hollow structure, with a smooth, rounded through-hole in the center for threading the baling rope. When fixed to a particular positioning surface and worn after use, the entire rope guide sleeve does not need to be replaced. Simply rotate the polygonal rope guide sleeve axially to select a worn rope guide groove for fixation, allowing continued use and extending the overall service life of the rope guide sleeve.

[0006] During installation, the positioning surface of a certain guide rope groove of this utility model is aligned with the working surface to complete the positioning, and then it is fixed.

[0007] During operation, the baling rope passes through the smooth, rounded hole at the center of the device, guiding it along a designated path and preventing it from becoming tangled and malfunctioning. When the baling rope wears down and the baling quality cannot be guaranteed, the positioning surface needs to be replaced. The specific procedure is as follows: axially rotate the polygonal rope guide sleeve, select an unworn positioning surface, and fix it in place; then it can continue to be used.

[0008] This utility model has the characteristics of long service life, low cost of use and simple structure. Attached Figure Description

[0009] The present invention will now be further described with reference to the accompanying drawings. Figure 1 This is a three-dimensional structural diagram of the present invention. Detailed Implementation

[0010] An improved baler guide loop, such as Figure 1 As shown, the baler guides the baling rope through a guide sleeve during baling. The guide sleeve has a through hole 2 at the center of a cylinder 1, and symmetrical discs 3 at both ends of the cylinder 1. Evenly distributed arc-shaped rope-guiding grooves 4 are provided on the circumference of each disc 3. The rope-guiding grooves 4 cooperate with the baling rope. A transition arc surface is provided at the junction of the outer end of the through hole 2 and the disc surface. The diameter of the through hole 2 is larger than the diameter of the baling rope. The number of rope-guiding grooves 4 is 4-6.
