The invention relates to the post-harvest processing of tobacco, in particular the preparation of tobacco for drying. The aim of the invention is to improve the performance of the device. FIG. 1 schematically shows a device;, FIG. 2 - a platform with a lever on an enlarged scale; in fig. 3 is a view A of FIG. 2

The device consists of a lift 1 for cassettes 2 with pushers 3 and a drive (not shown). The lift 1 is made in the form of a platform rotatable relative to the horizontal axis 4 and is provided with receiving levers 5 with locks 6 along the river. The free end of each lever is folded downward to allow entry under the guides 7 of the processing chamber 8 when the cassettes 2 are loaded. on the fixed end of the levers 5, Axis 4, on which the platform is mounted, is offset from the processing chamber 8 by 1/2 of the length of the cassette 2 "25

Shifting the axis of the hinges by 1/2 the length of the cassette from the plane passing through the points of contact of the cassettes with the stops and relative to the processing chamber allows the cassettes to be parallel with the guides of the processing chamber at the moment of their contact and precisely position it on them at the end of pushing. If this displacement is greater than 1/2 the length of the cassette, then the bottom of the cassette tends to fall below the direction of loading at the moment of loading, and if this distance is less than 1/2 the length of the cassette, then at the end of pushing it will be higher than the guides.

The receiving levers 5 with fix 1 and 6 are mounted on the platform (at an angle p to it) so that the cassette located on them takes a horizontal position at the moment of its contact with the guides of the processing chamber at points B (visible in Fig. 2). on the side)

Clamps and pushers are rigidly connected with the receiving levers, since their mutual arrangement is unchanged for all the Rus and it is more expedient to combine them into a single node and attach it to the platform at different angles p depending on the height of the Rus. Fastening the latches and pushers to the receiving levers simplifies the design and makes it more technological.

To enter the processing guide chambers when loading cassettes, the receiving levers are mounted at an angle to the cassette shelf. If this condition is not fulfilled (when the cassette is placed on the receiving levers and the angle ot is zero), then the free end of the levers is wedged in the guides, which makes the structure inoperable.

Keeping the cassette in a horizontal position at the moment of its contact with the guides at point B is performed by latches which are mounted on the receiving levers in the region of the cassette bottom. In order not to damage the cassette during its docking and loading into the processing chamber, the plunger has a circular shape in cross section.

The device works as follows.

Before starting, the platform is installed in front of the processing chamber 8 and fixed pivotally on the axis 4 in the brackets 9. The tobacco-filled cassettes 2 are installed with the bottom on the pushers 3, supporting them with clamps 6, and the shelves abut against the ends of the receiving arms 5. A drive (not shown) device rotates about axis 4, lifting the filled cassettes 2. As the cassette rises, the weight of the cassette moves from the pushers 3 to the latches 6 and the ends of the receiving pins 5, At the time the carriage of the cassette 2 with the guides 7 of the processing chamber 8 is set in parallel. As it moves further, the elevator; and the front part of the cassette approaches the guides 7, and the bottom at this time is raised and lowered onto the guides 7 at the end of pushing.

Raising and lowering the bottom of the cassette 2 from the parallel position with the guides 7 during pushing is done by shifting the axis 4 relative to the plane A, passing through the contact points of the cassettes 2 with the pushers and relative to the treatment chamber 8 by 1/2 the length of the cassette 2. the time for pushing the cassette 2 onto the guides 7 of the processing chamber 8 of the receiving arms is set under them.

After loading, the platform is lowered by the same drive to the initial horizontal position. The cycle is repeated until the entire bay

Before starting, the platform is installed in front of the processing chamber 8 and fixed pivotally on the axis 4 in the brackets 9. The tobacco-filled cassettes 2 are installed with the bottom on the pushers 3, supporting them with clamps 6, and the shelves abut against the ends of the receiving arms 5. A drive (not shown) device turns, with respect to axis 4, lifting the filled cassettes 2. As the cassette rises, the weight of the cassette passes from the pushers 3 to the latches 6 and the ends of the receiving pins 5, At the time of the cage of the cassette 2 with the guides 7, the processing chamber 8 has been installed parallel. As it moves further, the elevator; and the front part of the cassette approaches the guides 7, and the bottom at this time is raised and lowered onto the guides 7 at the end of pushing.

Raising and lowering the bottom of the cassette 2 from the parallel position with the guides 7 during pushing is done by shifting the axis 4 relative to the plane A, passing through the contact points of the cassettes 2 with the pushers and relative to the treatment chamber 8 by 1/2 the length of the cassette 2. the time for pushing the cassette 2 onto the guides 7 of the processing chamber 8 of the receiving arms is set under them.

After loading, the platform is lowered by the same drive to the initial horizontal position. The cycle is repeated until the entire compartment of the treatment chamber is filled, after which the platform is installed opposite the next compartment.

Thus, the invention makes it possible to increase the productivity of work by simultaneously loading several Rus and reducing the idle time during loading, as well as reduce the metal consumption and simplify the design.
