Embodiment Construction

[0022] Combine Figure 1 to Figure 7 , To further explain the present invention:

[0023] The grain sampling machine includes a column 70. A horizontally extending cantilever frame 80 is arranged at the upper end of the column 70. A rotating mechanism is arranged between the cantilever frame 80 and the column 70. The rotating mechanism drives the cantilever frame 80 to rotate around the column 70. The cantilever frame 80 A movable frame 10 is provided on the upper part, and the driving mechanism drives the movable frame 10 to reciprocate along the length direction of the cantilever frame 80. The movable frame 10 is provided with first and second guiding units, the first and second guiding units The area in between constitutes a clamping port for clamping the sampling tube 20. The first and second guide units each include a rotating shaft extending from the moving frame 10. The rotating shafts are both provided with driving wheels 11, and the two driving wheels 11 are provided wit...

Abstract

The invention relates to a grain sampling machine. The grain sampling machine comprises a cantilever rack arranged at the upper end of an upright column, wherein the cantilever rack is driven by a rotating mechanism to rotate around the upright column, a moving rack is arranged on the cantilever rack, a first feed guiding unit and a second feed guiding unit are arranged on the moving rack, each of the first feed guiding unit and the second feed guiding unit comprises a rotating shaft extending out of the moving rack, a driving wheel is arranged on the rotating shaft, a transmission chain is arranged on the two driving wheels and is further connected with a motor, a tension wheel is arranged on the moving rack and matched with the transmission chain, a detection wheel is further arranged between the tension wheel and the motor, is in abutting fit with the back surface of the transmission chain and is arranged on a stretching and retracting support, the stretching and retracting support is arranged on the moving rack and stretches and retracts horizontally, a proximity switch is arranged on a stretching and retracting path of the stretching and retracting support and is used for controlling power on and power off of the motor, the motor is powered off by the proximity switch, so that the phenomenon that a sampling tube is bent and scrapped or the phenomenon that the motor cannot rotate and is burnt due to overheat is avoided, and a driving mechanism and the sampling tube are protected.

Description

Technical field [0001] The invention relates to the technical field of grain detection equipment, in particular to a grain sampling machine. Background technique [0002] When the grain purchase station purchases foreign grain, in order to ensure the quality of the grain, it is necessary to sample the grain in the truck compartment before the grain is stored. Specifically, the dust content and moisture content of the grain can be obtained to know the quality of the grain. This is also the inspection item that the grain purchasing station must do before purchasing the grain. [0003] Existing grain acquisition stations also use grain samplers. The existing grain samplers are mostly hand-held structures. When the freight vehicle enters the area to be inspected in the grain acquisition station, the inspectors pass into the freight vehicle through the handheld sampler. In the body of the truck, the sampling operation of the grain in the truck is completed. The hand-held sampler in the...
