Abstract

The invention relates to conveyor equipment and is used when equipping belt conveyors transporting dust loads. The goal is to increase the tightness of the belt cover. The cover of the conveyor belt contains frames of section 2 of the conveyor, arcuate frames (DC) 1 installed on the frames of sections 2, and flexible shells (TH) 6 fixed to DC 1. The frames of sections 2 are provided with longitudinal guides. At the ends of the frames of sections DK 1 are fixed, and intermediate DK 1 are made in the form of rigid shells (LC) 5 of equal length and mounted on longitudinal guides with the possibility of their movement and placement of each next in the previous with a gap. At the same time, GO 6 segments are made with a length equal to the length of LC 5 and are connected to the ends of adjacent LC 5. The gap between the adjacent LC 5 is adapted to accommodate segment 6. It is made of DC 1 with spring clamps, and the edges of the outer LC 5 are triangular sections with the ability to interact with spring grippers. In the working position of the ZhO 5, they are moved apart until the extreme ZhO 5 is fixed in the spring clamps of DC 1. During the adjustment, repair, etc. The works on the conveyor in the required place of the LCO 5 are pushed one into the other, opening a section of the frame of the sections 2. At the same time, segments of GO 6 are placed in the gap between the adjacent LCS 5. This allows you to simply make up, repair, etc in any place of the closed conveyor belt.

(54) COVERING THE BELT CONVEYOR

(57) The invention relates to conveyor equipment and is used when equipping belt conveyors transporting dust loads. The goal is to increase the tightness of the belt cover. The cover of the conveyor belt contains frames of section 2 of the conveyor, arcuate frames (DC) 1 installed on the frames of sections 2, and flexible shells (GO) 6 mounted on DC1. The frames of sections 2 are provided with longitudinal guides. At the ends of the frames sections DK 1 fixed.

and the intermediate DCs 1 are made in the form of rigid shells (LC) 5 of equal length and mounted on longitudinal guides with the possibility of their movement and placement of each next in the previous one with a gap. At the same time, GO 6 segments are made with a length equal to the length of LC 5 and are connected to the ends of adjacent LC 5. The gap between the adjacent LC 5 is adapted to accommodate segment 6. It is made of DC 1 with spring clamps, and the edges of the outer LC 5 are triangular sections with the ability to interact with spring grippers. In the working position of the ZhO 5, they are moved apart until the extreme ZhO 5 is fixed in the spring clamps of DC 1. During the adjustment, repair, etc. The works on the conveyor in the required place of the LCO 5 are pushed one into the other, opening a section of the frame of the sections 2. At the same time, segments of GO 6 are placed in the gap between the adjacent LCS 5. This allows you to simply make up, repair, etc in any place of the closed conveyor belt.

cl

a and a

The invention relates to conveyor equipment, namely, devices for covering belt conveyors, and can be used to equip belt conveyors transporting dust loads.

The aim of the invention is to improve the tightness of the cover of the belt conveyor.

Figure 1 shows a fragment of a conveyor belt with a cover, side view; figure 2 - section aa in figure 1; FIG. 3 is a section 5-B in FIG. 1 (an attachment unit for edges of rigid shells with arcuate frames); Fig. 4 shows the cover of the cover of the conveyor section in the folded state; figure 5 and 6 - node

Figure 2 (cross section of longitudinal guides for rigid shells of various designs).

Shelter belt conveyor contains arcuate frames 1, mounted on the frame 2 sections of the conveyor and made with spring clamps 3, covers 4. Shells 4 include arc-shaped frames in the form

rigid shells 5 and flexible shells 6. The length of rigid 5 and flexible 6 shells is the same, while the casing 4 begins and ends with a rigid sheath 5. The edges 7 of the extreme hard shells 5 are made of triangular cross section with the ability to interact with spring grippers 3. To prevent spilling of the transported material and an increase in sealing between the lower and upper branches of the tape along the whole position of a metal sheet 8 is laid. To install the casing 4 on the frame 2 sections of the conveyor, consoles 9 are fixed, on which are mounted longitudinal ravl guides or rectangular shape 10 shown in Figure 5, or figured shape 11 shown in fig.b. The base shape of the rigid shells 5 is determined by the cross-sectional shape of the longitudinal guides 10 or 11. The longitudinal guides 10,11 may be continuous along the conveyor track.

When mounted, the housing 4 is installed; in the case of using guides 10 from above, in the case of using guides

I1 (shaped section) rigid shells 5 are mounted on one side of frame 2 sections in series with the installation of arcuate frames 1, while the longitudinal guides 11 do not reach the end of the conveyor belt by an amount equal to the length of the hard shell 5.

In its working position, the casing 4 is pulled apart until the extreme rigid shells 5 are fixed by spring grips 3 by the edges 7.

When carrying out adjustment, repair work on the conveyor in the desired location, the casing 4 is assembled by pushing the rigid shells 5 into each other, and in the gap between the shells 5, sections of the flexible sheath 6 are placed.

Shelter allows you to seal the entire conveyor, providing a dust-free

bulk cargo transportation. Using a suction fan with cleaning filters and tightly connected to a covered conveyor cavity, you can create a discharge that prevents the output

dusty air. The design of the proposed shelter provides fairly quick access to any place of the conveyor bed for its maintenance.
