CN201116236Y - Telescopic siphon of pneumatic grain elevator - Google Patents

Abstract

The utility model provides a suction pipe of a pneumatic grain elevator, which comprises the suction pipe and a supporting arm, wherein, the inner part of a master suction pipe is provided with a section of sleeve type telescopic suction pipe, a section of telescopic supporting arm is arranged on the master suction pipe and the sleeve suction pipe to control the length of the suction pipe; meanwhile, a suction pipe bottom is provided with the supporting arm to control the angle of the suction pipe. Compared with the prior art, the suction pipe has the advantages that the height and the length of the pneumatic grain elevator is telescopic at will, the working range of the suction pipe of the pneumatic grain elevator is widened, the working efficiency is improved, and both the labor and the material resources consumed for moving the pneumatic grain elevator are reduced.

Description

The grain elevator telescopic pipet

Technical field

The utility model relates to a kind of grain elevator suction pipe, especially a kind of grain elevator suction pipe that can stretch.

Background technology

The grain elevator that enterprises such as present grain distribution station use when daily use, exists the suction pipe length of grain elevator not enough usually, the perhaps limited problem of activity point of view, need mobile grain elevator could realize the operation purpose, and grain elevator is relatively heavy, has so just increased the difficulty of work.

Summary of the invention

The utility model provides a kind of suction pipe action radius big grain elevator at the defective of prior art.

To achieve these goals, the utility model takes following measure to realize:

A kind of grain elevator suction pipe comprises suction pipe, hold-down arm, it is characterized in that in female suction pipe, adding the preceding paragraph telescopic suction pipe, and on female suction pipe and sleeve suction pipe, add one section telescopic boom control suction pipe length, hold-down arm control suction pipe angle is set in the suction pipe bottom simultaneously.

The utility model has following characteristics with respect to prior art: so just can realize the height of grain elevator and stretching arbitrarily of length, enlarge the operating range of grain elevator suction pipe, increase work efficiency, reduce the man power and material that mobile grain elevator expends.

Description of drawings

Accompanying drawing is the structural representation of grain elevator suction pipe.

Wherein: 1, food sucking pipe hold-down arm, 2, flexible hold-down arm, 3, the suction pipe main body, 4, the telescopic suction pipe

The specific embodiment

Further be illustrated in conjunction with the accompanying drawings:

Food sucking pipe hold-down arm 1 is supported on grain elevator main body and the suction pipe main body 3, grasp the differences in angle of grain elevator suction pipe by stretching of food sucking pipe hold-down arm 1, at the front end of suction pipe main body 3, added one section telescopic suction pipe 4, by flexible hold-down arm 2 control suction pipe entire length.

So just realized having enlarged the operating range of grain elevator suction pipe under the situation that grain elevator need not move, realized the saving of manpower and materials and the raising of work efficiency.

Claims (1)

1. a grain elevator suction pipe comprises suction pipe, hold-down arm, it is characterized in that in female suction pipe, adding the preceding paragraph telescopic suction pipe, and on female suction pipe and sleeve suction pipe, add one section telescopic boom control suction pipe length, hold-down arm control suction pipe angle is set in the suction pipe bottom simultaneously.
