Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] The embodiment of the invention discloses a grain quantitative skewer, which divides the skewered grain samples, precisely controls the skewer amount of each layer of grain, and improves the representativeness of the samples sent for inspection.

[0023] Such as Figure 1 to Figure 3 As shown, a grain quantitative skewer includes a body 1. The body 1 is provided with a negative pressure device 2, a sample collection chamber 3, a div...

Abstract

The invention discloses a grain quantitative sampler which comprises a body. A negative-pressure device, a sampling chamber, a splitting device and a sampling mechanism are arranged on the body. The negative-pressure device is connected to the sampling chamber and used for generating negative pressure in the sampling chamber, the wall surface of the sampling chamber is provided with a sampling port connected with a sampling tube, the bottom of the sampling chamber is provided with a discharging port, and a sampling switch mechanism is arranged at the discharging port which is connected to thesplitting device. An outlet of the splitting device is connected to the sampling mechanism, and the sampling mechanism comprises a sampling hopper for sample receiving and a weighing device for bearing the sampling hopper. The grain quantitative sampler has advantages that sampling is performed by vacuum suction, sampled samples are proportionally split through the splitting device and weighed inreal time through the weighing device, sampling quality of each layer of grains can be accurately controlled, and sample representativeness is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of skewer, in particular to a grain quantitative skewer. Background technique [0002] For bulk grains and oilseeds, set points according to the shape and area of ​​the pile, and layer samples according to the height of the pile. The steps and methods are as follows. The points are set according to the area of ​​each area not exceeding 50m. 2 , Each district has a center, four corners and five points. If the number of districts is two or more, the two points on the boundary of the two districts are the common points (a total of eight points in the two districts, a total of eleven points in the three districts, and so on), the points on the edge of the grain pile Set at a distance of about 50cm from the edge; stratification: the pile height is less than 2m, divided into upper and lower layers; the pile height is 2 to 3m, divided into upper, middle and lower three layers, the upper layer is 10-20cm below the grain ...
