Ring joint and fixed pull force cracking leather cylinder for material distribution belt machine

Abstract

The invention relates to a ring joint and fixed pull force cracking leather cylinder for a material distribution belt machine. The leather cylinder comprises an upper joint leather cylinder and a lower joint leather cylinder, wherein leather cylinder end opening pull rings are arranged on the upper joint leather cylinder and the lower joint leather cylinder; and one fixed pull force cracking ring is arranged between every two leather cylinder end opening pull rings; and an invisible crack is formed on each fixed pull force cracking ring. According to the ring joint and fixed pull force cracking leather cylinder for the material distribution belt machine, the length of the leather cylinder can be customized according to actual production, and the pouring requirements of various altitude difference bins are met by combining the leather cylinders of several length models. The elliptical fixed pull force cracking rings penetrate between the upper joint leather cylinder and the lower joint leather cylinder and are used for connecting the upper joint leather cylinder and the lower joint leather cylinder; and when the overloading of the leather cylinders caused by material blockage occurs, the fixed pull force cracking rings are released due to the overloading, and the lower joint leather cylinder drops down naturally, so that the tipover of protective equipment due to the overloading is avoided. The fixed pull force cracking rings can also be independently applied to other occasions where fixed pull force cracking is required.

Description

technical field [0001] The invention relates to a cloth belt conveyor part, in particular to a ring-connected, fixed-tension split-type leather cylinder applied to the cloth belt conveyor. Background technique [0002] Concrete pouring equipment such as tower belt conveyors, tire belt conveyors, and distributing conveyors often encounter a large height difference between the unloading point of the belt conveyor and the warehouse surface during pouring. In order to avoid the separation of concrete aggregates, it is now used at the end of the belt conveyor Set the leather tube to achieve the purpose of avoiding the separation of concrete aggregates. However, the existing leather cylinders are generally of a fixed length and cannot adapt to the use requirements of different height differences, and when the leather cylinder is blocked by material, it may cause an accident of the material distributing equipment tipping over.

AI Technical Summary

Problems solved by technology

However, the existing leather cylinders are generally of a fixed length, which cannot adapt to the use requirements of different height differences, and may cause an accident of tipping of the material distribution equipment when the leather cylinder is blocked.

[0003] The main disadvantages of the prior art are as follows: 1. The length of the leather tube is fixed, which requires frequent replacement and poor economy

At present, the leather tube connected to the end of the cloth belt of the concrete pouring equipment is generally a fixed-length leather tube. However, due to the large difference in height difference between the pouring parts, the fixed-length leather tube is often difficult to meet the requirements. If the leather tube is too long, the cloth belt forms an elevation angle, reducing the The pouring efficiency increases the quality problems caused by the drop of concrete from a high place. The too short skin tube will increase the falling section of the concrete without the skin tube guide material, which will easily lead to the separation of concrete aggregates and non-concentration of the distribution, resulting in quality and efficiency problems.

For example, the preparation of leather cylinders of various lengths is troublesome to replace, and economic problems caused by large reserves of leather cylinders

[0004] 2. There is a safety hazard in the blocking material

If both the alarm and tripping functions of the protective device are put into use, when overload occurs, the concrete inside the leather tube and the leather tube will fall together. Due to the large height difference, the falling direction is uncertain, and the pouring warehouse is often crowded with personnel and equipment, which is easy to Cause casualties and equipment property loss; if only the alarm and shutdown functions of the protective device are used, and the tripping function is not used, when the alarm displays an alarm, due to the shutdown delay and belt inertia, some concrete will still be sent into the leather barrel. May cause pouring equipment to tip over due to overload
