Abstract

The invention relates to chain conveyors intended for the transport of bulk materials, and may be used in the milling, feed, food, chemical and other sectors. The purpose of the invention is to increase the durability and load capacity by reducing the kinematic elongations of the branches of the endless raznozagovoy open hinge plate chain (PC). The conveyor contains a two-way drive sprocket 1, a tension roller 4, mounted on axis 5, consisting of internal 6 and external 7 links of the central pistol, and straight-line guides 10-13 for links 14-17 PC with rollers (B) 18-21 The number Z of teeth of an asterisk 1 is determined from the mathematical relationship 9 + 8n, where n is the number of natural numbers and numbers. A plug-in connecting element in the form of a connected inner link 26 and an outer link 27 is installed in the contour of the PC, with an angular engagement with an asterisk 1 equal to the average engagement step with an asterisk 1 of links 6.7. The number of teeth Z of the asterisk 1 with the connecting element is determined from the mathematical dependence Z 6 + 8n {7 + 8n; 8 + 8n and Z 1H-8n; : i2 + 8n respectively (L

The invention relates to chain conveyors intended for the transport of bulk materials and can be applied in the milling, {elevator, feed mill, food, chemical and other industries,

: The aim of the invention is to increase the durability and load capacity by reducing the kinematic elongations of the branches of the endless razneagogovoy open-hinged plate chain.

FIG. 1 shows a conveyor in general view; FIG. 2 — view A in FIG. one . The chain conveyor contains a two-way drive sprocket 1, the shaft 2 of which is mounted in the housing 3, a tension roller 4, rotatably movably mounted on the axis 5. The asterisk 1 and the roller 4 are covered by an infinite razneagogovy open-hinged plastic chain consisting of internal

6 and outer 7 links. In the plates of the inner links b twin holes are made, in one case of each of which a shaped roller 8 is pressed, and the second half is intended for free passage of the round roller 9 of the outer link 7, the chain is filled with various steps, t. e. the distance between the neighbors of the axes of the round rollers 9, reinforced

on the pastes of the same external link 7, there is a large distance between the adjacent axes of the round-shafts 9 located at the ends of the internal link. Outdoor

7 and the internal links are a pair of chain-link links. Mean step of the considered chain or

its pair of links equals half-steps

. In case 3, a hardened longitudinal guide 10-13 for links is called 17 s B 20p 24. B 19j 23 increases the length of the contour U, and displacement B 18 22 reduces the length of the PC contour, while providing minimal changes in the length of the contour . 2 Il.

respectively, 14-17, which are simultaneously, and in conjunction with asterisk 1 or the roller r. The circular rollers of the links 14-17, which are engaged with the asterisk 1 and the roller 4, are designated by the positions 18-215, respectively, and the circular rollers of the 3Ti-ix of the same links, which are located at the longitudinal guides, are respectively marked 22-25, the shaft 2 is driven the sprocket 1 is associated with a rotary motion drive (not shown),

Between the constructive parameters of the drive sprocket 1 and the infinite traction chain, which includes the sprocket 1 and the roller 45, the following relations are provided

In the contour of an endless traction chain containing links 6 and 7 there is a plug-in connecting element in the form of connecting cables between one internal link 26 and one external link 27, structurally similar to the other corresponding links in this chain. The plug-in h.; ohm engagement, with an asterisk 1S raschzgm middle hu- 1 At the engagement with an asterisk 1 inner 6 and outer 7 links,

In addition, the number of teeth Z by registering an asterisk 1 is determined without the insertion element by the mathematical dependence

Chain conveyor works as follows.

The shaft 2 of the drive sprocket 1 is reported to have a rotational movement from the drive in the direction of the arrow in FIG.

At the initial moment of time, an asterisk 1 enters the chain 15 chain with rollers 19 and 23 at its ends, runs link 14 with rollers 18 and 22, a link 17 with rollers 21 and 25 runs down link 4 with rollers 20 and 24. During operation of the device, for any elementary period of time, the movement of the roller 23 of the incidental link 15 is different from the movement of the roller 22 of the descending link 14, and also the movement of the roller 25 of the incidental link 17 differs from the movement of the roller 24 of the escapement 16. The movement of the rollers of the incident links increases long an endless chain in a closed loop circuit, and the running down movement of the roller units reduce the length of said loop. At the same time, the algebra-w-gesk sum of these elementary displacements is equal to the absolute elongation of the chain contour, and in the process of operation of the chain conveyor it is provided the smallest. As a result of minimal changes in the length of the chain loop, periodic elastic deformations of the chain and pulsating loads are significantly reduced.
