UA8232U - Belt of a chain and rod conveyer - Google Patents

Abstract

A belt of a chain and rod conveyer consists of two roller chains, placed in parallel, and supporting units of rods. It is supplemented with modified outer plates, into which the axle of the frame, formed by means of connecting two carrier rods, is inserted. In order to prevent turning the frame around axles, the axles of the frames are made as those of square profile.

Description

Description of the invention

The useful model belongs to the field of general mechanical engineering, in particular, to the transport bodies of 2 machines for harvesting root and tuber crops and can be used in the manufacture of chain-rod conveyors.

Known conveyors of harvesting machines, consisting of two parallel roller chains, having outer and inner plates connected to each other by rods evenly located in one plane at a distance from each other equal to the chain pitch.

The disadvantage of the generally accepted design should be considered the complexity during installation (provided that the standardized technical requirements for chains are met), which influenced the change of the main standard dimensions of the chain parts to facilitate assembly and subsequently significantly affects the operational properties of the conveyor.

In addition, the bars for such a design must be made of high-quality steel grades and have a calibrated 72 surface, as they are simultaneously the axis of the chains, which is not profitable enough given that the bar is the basic component of the entire conveyor.

A useful model sets the task of ensuring a simple, fast and reliable assembly of the conveyor, without deviating from the technical requirements for chains during manufacture; to increase the operational resource and ensure the use of rods made of economically beneficial materials and without calibrated surfaces.

The task set by the useful model is that in the chain-bar conveyor, which consists of two parallel roller chains and rod support nodes, according to the useful model, the external plates are modified, into which the axis of the frame is inserted, which is formed by the connection of two carrier bars, and to rotate the frame around the axes of the frame axes, a square profile is made or rubber rings are used, which are put on two adjacent frame bars.

Fig. 1 shows the general view of the conveyor, top view in Fig. 2 - cross-section A-A Fig. 1.

The chain-rod conveyor consists of two parallel drive roller chains 1 and 2, which are mirror images of each other, and contain elements of the drive chain: the block of the inner link 3, and the modified outer plates 4 are connected to each other by the axis 8. Bearing the canvas of the conveyor is created by the bars of 5 frames, which are connected in pairs to the axis of the frame b. The axis b is installed in the holes of the outer plates 4. From turning the axis frame 6, a square profile is made or a rubber ring 7 is used, which is put on the rods 5 of two adjacent frames. high school

The chain conveyor belt conveyor is made as follows. Blocks of internal links of drive chains 1 and 2 are manufactured as standardized parts of drive chains. The outer plate 4 is modified to create a profile such that when the frames are installed, the axis 6 will not interfere with the engagement of the drive chain 1 and 2 with the sprockets on the drive shaft (not shown in the figures). When assembling, the drive chains are first made by mounting the blocks of the inner link Z, with the outer plates 4, which are pressed onto the axis of the drive chains 8. Frames are made to ensure the required width 8 of the canvas. The axes of the frames are installed in the holes of the outer plates 4 and are splined. The conveyor is driven from the drive shaft (not shown in the figures). The pile moves along the belt of the conveyor c, moving and simultaneously being cleaned of impurities falling into the gaps between the bars 5. c" Thus, we get a conveyor design whose traction chains will be assembled like ordinary standardized chains, which will greatly simplify the installation. The improved design significantly increases the resource of the conveyor in comparison with the traditional design due to the assembly of drive chains in compliance with 49 technical requirements, and overall maintainability and reliability are also increased. Rods will not require specialized manufacturing, high-quality steel grades and calibrated surfaces. They can be used with larger or smaller diameters and different shapes as needed. 2 o PO z z no B and y
