Description

Devices are known for the mechanized transportation of tobacco-drying frames used in solar drying, equipped with road rollers, including an endless cable for advancing frames, horizontal and inclined nanravlai and mechanisms of engagement of the frames.

The described device has the peculiarity that, for the purpose of automatically engaging the frames between themselves with opposite ends when rolling them out of the sar and with the ends of the same name when rolling into the shed, the frames are equipped with pressure rollers mounted on them that cantilever onto them, and the mechanism of engagement is made in the form of pairs mounted on the ends of the axes "Left running rollers of frames of rotary spring-loaded double-arm levers having a notch on one shoulder for axes of running rollers of the frame in front, and on the other shoulder a roller interacting with the restart mechanism lepi memory mounted on

paths of movement of the latter and driven by a pressure roller.

FIG. 1 shows a general view of the device; in fig. 2 is a top view; in fig. 3-6-mechanism re-link. (Eni in four characteristic positions, side view.

The unit is intended for mechanized transport |) with tobacco leaves from sar on co.: 1 finger (roll out of frames) and reverse transport (roll in) ral; in a shed, which, according to the terms of the technology of drying tobacco, is done several times a day.

The frames on which the inlry with tobacco leaves are fixed are square and manufactured in short; 1.: 1 pipes or from wood.

D.1 direction, the lower / and upper 2 angled iron tracks are designed in the frame. In the first and second way, in the shed and from the entrance to it the frames BijOic.incH are inclined and somewhat

wider than the lower horizontal path / laid on the drying pad. Each frame at the ends of the left side is provided with two single-track rollers 4, leaning imis on track 1 rails, and on the ends of the right side - two two-roller rollers 5 resting on the track rails, / when the frame is horizontal and on the rails of track 2 when climbing on them and inclined arrangement of frames in the form of a "package in the barn.

For mixing frames on rails of tracks 1 to 2, an endless rope 6, enclosed in a groove between track posts, an endless rope 6, spanning a drum 7, driven by an electric motor 8, and a tension block 9, is applied. The corresponding hook and does not constitute features of the invention.

At the ends of the axes of the left-side running rollers 4, two shoulders levers 10 are put in pairs and pivotally, having a notch 11 for the longer arm for the left-running roller axis of the front frame, and the other shoulder is a roller 12. By the spring 13 the lever 10 is pulled back towards the frame 3.

Along the path of the frames, at the beginning of the ascent of the path 2, a frame re-linking mechanism, made in the form of a two-arm lever 14, pivotal on the axis 15 and lifted by a long arm somewhat higher than the track rails / spring 16, is installed on the appropriate rack A. The long arm of the lever 14 interacts with its bend with roller 17 in front of the running frame, console mounted on the left side of each frame. In order to ensure that the recesses of the levers 10. Of the mechanism of re-linking the ends of the axes of the rollers 5 of the frame are rolled out when the frames are rolled out of the sar, the stop lever 20, which interacts with the roller 4, is swiveled on the axis 18 and retracts by a short shoulder with a spring 19. the frame and the braking movement of its and subsequent frames until such time as the frame in front of it assumes a horizontal position. For

the time delay of the rollers 4 at the point of re-linking of the frames by the track rails / are provided with a recess 21 receiving the roller 4 of the left side of the adjacent frame. Above the notches 21 are mounted the supporting rollers levers 22, which are under the action of the springs 23.

At. roll out of frames. Sarah rollers 17 of the first frame, pressing on the long shoulders of the levers 14, turn them around the axles 15, overcoming the resistance of the springs 16.

The short arms of the arms 14, lifting, rest against the rollers 12 of the arms 10 of the second frame, the short arms of which free the lower side of the first frame. In this way, the first frame is separated from the frame pack and. can be stretched to the actual site.

The left rollers 4 of the first frame press the left shoulders of the stop levers 20 and, overcoming the resistance of the springs 19, lift their right shoulders abutting against the rollers 4 of the second frame and completely excluding the possibility of further movement of it and the entire frame pack.

After the first frame, freed from the levers 10 of the second frame, passes a distance equal to its length, the right side of the first frame, descending along an inclined path, hits the lever 10 of the second frame with its right side.

The first frame, hitting its right side into the recesses of the levers 10 of the second frame, i.e., having re-hooked, with further movement begins to pull out from the sar the second one and the entire frame package linked to it.

At the right moment, the left side of the second frame is lowered by the levers of the third frame, and so on, until all the frames are linked to each other in a chain moving along the drying path.

Rolling frames in reverse order.

Subject invention

Claims (3)

1. A device for mechanized transportation of tobacco-drying frames used in solar drying and equipped with running gears. rollers, including an endless cable for advancing frames, horizontal and inclined guides, and a mechanism for engaging frames, characterized in that, in order to automatically engage the frames between each other with opposite ends when rolling them out of the shed and with the same ends when rolling into the shed, the frames are fitted with cantilevers they are pressed with rollers, and the mechanism of engagement is made in the form of pair-mounted on the ends of the axes of the "left running rollers of the frames of the rotatable spring-loaded two-arm levers having a recess for the x-axes on one shoulder rollers in front of the running frame, and on the other shoulder a roller interacting with the frame re-linking mechanism installed along the path the latter and driven by a pressure roller. 2. The device according to claim 1, characterized in that the re-linking mechanism is made in the form of a two-armed spring-loaded lever. 3. The device according to paragraphs. 1 and 2, in order to ensure that each subsequent frame of the right ends of the frame in front of the last frame is rolled out of the sar to the sub platform, each spring frame is inserted into the recesses of the subsequent frame, a spring-loaded moan arm is installed, interacting with left rollers of adjacent frames and providing the brake for subsequent frames until the frame in front of it reaches a horizontal position.
