Automatic grain sampler

Abstract

The invention discloses an automatic grain sampler. The automatic grain sampler comprises a longitudinal traveling cart which is arranged on longitudinal traveling tracks, two transverse traveling trolleys which are arranged on transverse traveling tracks of the longitudinal traveling cart, and fiche chain transmission lifting mechanisms which are arranged on the transverse traveling trolleys. The automatic grain sampler is characterized in that: a longitudinal traveling cart reducing motor drives a driving shaft of the cart by a chain wheel, and traveling wheels of the cart which are positioned at both ends of the driving shaft and a driven shaft of the cart are arranged on the longitudinal traveling tracks; the two transverse traveling trolleys have the same structure, a driving sprocket of a transverse traveling reducing motor shaft of one trolley is connected with a driven sprocket of a transverse traveling reducing motor shaft of the other trolley through a trolley chain, and moving rollers of the trolleys are arranged on the transverse traveling tracks; and driving sprockets of fiche lifting reducing motor shafts of the fiche chain transmission lifting mechanisms are connected with driven sprockets of sprocket adjustment shafts of the trolleys through fiche chains, and the fiche chains are fixedly connected with fiches. The automatic grain sampler has the advantages of simple structure, high manufacturing and assembly processability, low cost, high performance-price ratio and the like, and can be operated stably.

A longitudinal traveling cart is equipped with a motor at both ends of the cart frame, and the two motors drive the cart to walk along the longitudinal...

AI Technical Summary

Problems solved by technology

A longitudinal traveling cart is equipped with a motor at both ends of the cart frame, and the two motors drive the cart to walk along the longitudinal traveling track through a gear transmission. Due to the structure of two-way driving of the large wheel by two motors , there is a non-synchronous phenomenon, which causes the cart to run unstable, and the manufacturing and assembly precision of the large wheel and the large wheel frame is high, the manufacturing efficiency is low, and the cost is high; the two motors of the two transverse traveling trolleys are installed on the rear side of the trolley track , drive the wheels on the track of the trolley to move laterally through the gear transmission, the same problem as the big trolley, there is also a non-synchronous phenomenon, which makes the trolley run unstable, its structure is complex, the manufacturing and assembly precision is high, and the upper part of the trolley is supported by auxiliary support On one side, the support wheel is a cantilever beam mechanism, which has poor stability; the skewer adopts a skewer transmission box lifting mechanism and a skewer chain drive two-stage lifting mechanism, and a counterweight box is set at the rear of the lower part of the trolley to ensure the stability of the trolley’s lateral movement , its structure is complex, similarly, the manufacturing and assembly precision requirements are high, the manufacturing efficiency is low, and the cost is high
