Lifting type auxiliary hanging rod device for tobacco curing barn

Abstract

The utility model relates to the technical field of auxiliary devices of tobacco curing barns, in particular to a lifting type auxiliary hanging rod device of a tobacco curing barn. By designing a lifting rod assembly and a cross rod assembly with specific structures and position relations, when a threaded sleeve on one side rotates, the threaded sleeve on the side can be controlled to ascend and descend through threaded fit with a threaded rod, in the process, a first bevel gear drives a second bevel gear to rotate synchronously, and then a cross rod body is driven to rotate; therefore, the first bevel gear on the other side is driven to rotate, the threaded sleeve on the other side is driven to rotate relative to the threaded rod, the threaded sleeves on the two sides synchronously ascend or descend, the two sides do not need to be controlled to ascend or descend at the same time, and the transverse rod body can be stably kept in the horizontal state all the time. And the situation that the transverse rod body inclines and even the threaded rod and the threaded sleeve are blocked due to asynchronous lifting of the two sides is avoided.

[0031] To make the technical content of the utility model, the purpose and effect realized clear, the following will be described in detail in combination with the embodiment and the drawings.

[0032] Please refer to Figures 1 to 5 The utility model embodiment relates to a tobacco curing barn lifting type auxiliary hanging rod device, including base 1 and two groups of lifting hanging mechanisms along Y direction symmetry each other connected in the upper portion of base 1;

[0033] The lifting hanging mechanism includes two lifting rod assemblies 2 along X direction symmetry each other;

[0034] The lifting rod assembly 2 includes threaded rod 21, threaded sleeve 22, first bevel gear 23 and bearing seat 24;

[0035] The axial direction of threaded rod 21 is vertical direction, and the lower end of threaded rod 21 is fixed to base 1;

[0036] The threaded sleeve 22 is threadedly sleeved on threaded rod 21;

[0037] The first bevel gear 23 is coaxially sleeved on threaded sleeve 22;

[0038] The bearing seat 24 is connected to the upper end of threaded sleeve 22, and the axial direction of bearing seat 24 is X direction;

[0039] The lifting hanging mechanism further includes cross rod assembly 3;

[0040] The cross rod assembly 3 includes cross rod body 31, and both ends of cross rod body 31 are rotatably connected to bearing seat 24 respectively; ​​

[0041] The second bevel gears 32 coaxially sleeved at both ends of the crossbar body 31 are engaged with the first bevel gears 23, and the two crossbar bodies 31 are used for erecting the tobacco hanging rods 4.

[0042] In the above embodiment, the position of the crossbar body 31 can be first adjusted to be lowered by adjusting the threaded sleeve 22 of one side of the two lifting hanging mechanisms, then the tobacco hanging rods 4 with bundled tobacco leaves are hung at both ends of the two crossbar bodies 31, and then the threaded sleeve 22 of one side of the two lifting hanging mechanisms is simultaneously controlled to rotate, so as to drive the crossbar body 31 to horizontally rise, thereby driving the tobacco hanging rods 4 to stably rise, and the purpose of stably adjusting the height of the tobacco hanging rods 4 is achieved.

[0043] In the above embodiment, by designing the lifting rod assembly 2 and the crossbar assembly 3 with specific structures and positional relationships, when the user needs to adjust the height of the crossbar assembly 3, only the threaded sleeve 22 of one side of the lifting rod assembly 2 needs to be rotated, and when the threaded sleeve 22 of one side is rotated, the threaded sleeve 22 of the side can be controlled to rise and fall through the threaded cooperation with the threaded rod 21. In this process, the second bevel gears 32 are driven to synchronously rotate by the first bevel gears 23, and then the crossbar body 31 is driven to rotate, thereby driving the first bevel gears 23 of the other side to rotate, so as to drive the threaded sleeve 22 of the other side to rotate relative to the threaded rod 21, so that the threaded sleeves of the two sides synchronously rise or fall, and it is no longer necessary to simultaneously control the lifting of the two sides, so that the crossbar body 31 can be stably kept in a horizontal state, and the situation that the crossbar body 31 is inclined or the threaded rod 21 and the threaded sleeve 22 are stuck due to the asynchronous lifting of the two sides is avoided.

[0044] As a preferred embodiment, the crossbar body 31 is provided with a plurality of annular grooves 33 distributed at equal intervals along the axial direction of the crossbar body 31, and the annular grooves 33 are used for erecting the tobacco hanging rods 4.

[0045] In the above embodiment, by designing the structure of the annular groove 33, the tobacco hanging rod 4 is limited on the crossbar body 31, so as to avoid the axial sliding of the tobacco hanging rod 4 on the crossbar body 31 during the lifting of the crossbar body 31.

[0046] As a preferred embodiment, the distance between the adjacent two annular grooves 33 is 20-30 cm.

[0047] As a preferred embodiment, the annular groove 33 is coaxially sleeved with a rolling sleeve 34 at the position, the circumferential surface of the rolling sleeve 34 is an anti-skid surface, and the anti-skid surface is used for erecting the tobacco hanging rod 4.

[0048] In the above embodiment, since the horizontal rod body 31 rotates with the transmission of the second bevel gear 32 during lifting, the anti-skid surface of the rolling sleeve 34 is connected with the lower part of the cigarette hanging rod 4 by setting the rolling sleeve 34 structure, so that the rolling sleeve 34 does not rotate when the horizontal rod body 31 rotates, thereby avoiding the position of the cigarette hanging rod 4 from moving during lifting and descending, and further improving the stability of the height adjustment of the cigarette hanging rod 4.

[0049] As a preferred embodiment, the circumferential surface of the rolling sleeve 34 is an arc surface, further improving the stability of the height adjustment of the cigarette hanging rod 4.
