Abstract

The utility model discloses a heading machine first conveyor chute follow-up mechanism and belongs to the field of engineering machinery. The heading machine first conveyor chute follow-up mechanism comprises a shovel board, a first conveyor, a first hinge pin, a second hinge pin, a third hinge pin, a fourth hinge pin, a rear bearing, a connecting rod and a body. A hinge point of the shovel board is mounted on the body through the second hinge pin, a hinge point of the connecting rod is mounted on the rear bearing through the fourth hinge pin, a front hinge point of the first conveyor is connected with the shovel board through the first hinge pin, and a rear hinge point of the first conveyor is connected with the connecting rod through the third hinge pin. Four hinge points form a double-rocker mechanism and achieve follow-up of a first conveyor chute, so that a chute of the shovel board is smoothly connected with the first conveyor chute after rotation, a conveying chain is effectively prevented from being blocked, and a heading machine is ensured to normally construct.

Description

First conveyer of digging machine chute follower

Technical field

The utility model relates to a kind of development machine, and specifically a kind of first conveyer of digging machine chute follower belongs to engineering machinery field.

Background technology

Development machine is be used to the machine of digging straight underground passage; Development machine is divided into open type development machine, shield formula development machine and boom-type roadheader.Mainly formed by walking mechanism, operating mechanism, shipment activity and transferring mechanism.

First conveyer of digging machine chute and shovel board chute are in smoothing junction, pass through smoothly to guarantee conveyer chain.But when the shovel board lift work, first conveyor is installed fixing, and the shovel board chute after the rotation and the smooth connection between the first conveyor chute change, and can cause conveyer chain to be blocked; Cause development machine to construct.

Summary of the invention

For the problem that above-mentioned prior art exists, the utility model provides a kind of first conveyer of digging machine chute follower, and is in smoothing junction between shovel board chute and the first conveyor chute, effectively avoids conveyer chain to block.

To achieve these goals, the technical solution adopted in the utility model is: a kind of first conveyer of digging machine chute follower, comprise shovel board, first conveyor, bearing pin one, bearing pin two, bearing pin three, bearing pin four, rear support, connecting rod and body, the shovel board hinge is installed on the body by bearing pin two, the connecting rod hinge is installed on the rear support by bearing pin four, hinge is connected with shovel board by bearing pin one before the first conveyor, and hinge is connected with connecting rod by bearing pin three behind the first conveyor.

Further, described four hinges form double rocker mechanism.

Further, described body and rear support maintain static as fuselage.

The beneficial effects of the utility model are: four hinges have formed double rocker mechanism, realize the servo-actuated of first conveyor chute, make between shovel board chute after the rotation and the first conveyor chute in smoothing junctionly, effectively avoid conveyer chain to block, guaranteed the development machine normal construction.

Fig. 2 is Fig. 1 shovel board chute and first conveyor chute connection diagram;

Fig. 3 is A-A sectional view among Fig. 1;

Fig. 4 is connecting rod schematic diagram among Fig. 1.

Among the figure: 1, shovel board, 2, first conveyor, 3, bearing pin one, 4, bearing pin two, 5, bearing pin three, 6, bearing pin four, 7, rear support, 8, connecting rod, 9, body, 10, the shovel board chute, 11, the first conveyor chute.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of first conveyer of digging machine chute follower, comprise shovel board 1, first conveyor 2, bearing pin 1, bearing pin 24, bearing pin 35, bearing pin 46, rear support 7, connecting rod 8 and body 9, shovel board 1 hinge is installed on the body 9 by bearing pin 24, connecting rod 8 hinges are installed on the rear support 7 by bearing pin 46, first conveyor 2 front hinges are connected with shovel board 1 by bearing pin 1, and first conveyor 2 rear hinges are connected with connecting rod 8 by bearing pin 35; Described four hinges form double rocker mechanism; Described body 9 and rear support 7 maintain static as fuselage.

After the installation, four hinges form double rocker mechanism, arbitrarily oscilaltion; Shovel board 1 moves up and down around bearing pin 24, first conveyor 2 rotates with shovel board 1 by bearing pin 1, driving connecting rod 8 by bearing pin 35 rotates around bearing pin 46, first conveyor chute 11 has guaranteed the smooth connection of shovel board chute 10 and first conveyor chute 11 along with shovel board chute 10 rotates together.
