[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] See also Figures 1 to 3 As shown;

[0047] This embodiment discloses a grain sample stirring and quantitative conveying device, which includes:

[0048] Multiple shakers 1 for receiving grain samples delivered by the grain supply equipment at the upstream end of the process;

[0049] A grain hopper 2 is located below the multiple shakers 1 and is connected to the feed port of the shakers 1 for receiving grain samples. The grain hopper 2 has a stirring assembly 3 integrated therein. The stirring assembly 3 stirs the grain sample in the grain hopper 2 via a stirring blade 302 located near the bottom of the grain hopper 2; and

[0050] A material delivery pipeline group connected to the lower end discharge port of the grain hopper 2;

[0051] The material conveying pipeline group includes:

[0052] A surplus grain pipeline 401 in communication with the grain hopper 2; and

[0053] a quantitative pipeline 402 connected to the surplus grain pipeline 401;

[0054] The grain sample outputted from the grain hopper 2 partially enters the quantitative pipe 402 through the surplus grain pipe 401, and partially enters the surplus grain box 5 below the device through the surplus grain pipe 401;

[0055] A plug-in electric valve is installed on the quantitative pipeline 402 to control the connection state of the quantitative pipeline 402 through the plug-in electric valve.

[0056] Specifically, this embodiment discloses a grain sample stirring and quantitative conveying device, which includes a grain hopper 2 and a shaker 1. The shaker 1 is arranged near the feeding end of the grain hopper 2 and conveys the grain sample into the grain hopper 2 after dust removal. The grain hopper 2 of this embodiment is integrated with a stirring component 3, which stirs the grain sample in the grain hopper 2 evenly through the stirring component 3 and then outputs it through a feeding pipeline group. The feeding pipeline group of this embodiment is divided into a surplus grain pipeline 401 and a quantitative pipeline 402. After the surplus grain pipeline 401 receives the material output by the grain hopper 2, part of the material will enter the quantitative pipeline 402 connected to it through the side wall of the surplus grain pipeline 401. The position of the plug-in electric valve on the quantitative pipeline 402 is set, and the plug-in electric valve and the quantitative pipeline 402 are used to determine the volume of the stored material, thereby realizing quantitative feeding. The excess surplus material enters the surplus grain box 5 for storage through the surplus grain pipeline 401. The device of this embodiment uses the stirring assembly 3 to achieve automatic stirring, and uses the surplus grain pipeline 401 and the quantitative pipeline 402 to achieve quantitative storage of materials and then transport them to the laboratory, with a high degree of automation and higher precision control.

[0057] Preferably, the device of this embodiment further includes a steel structure frame 10;

[0058] The grain hopper 2 is fixed to the upper part of the steel structure frame 10 through the steel structure crossbeam 11. A plurality of shakers 1 are arranged at intervals on the upper end of the grain hopper 2. The discharge port of the shaker 1 is controlled by the electric grain discharge door 101.

[0059] A bottom crossbeam 12 is provided at the lower portion of the steel structure frame 10 , and the bottom crossbeam 12 is used to fix the surplus grain box 5 ;

[0060] A sample receiving platform 13 is provided at the bottom of the steel structure frame 10 .

[0061] Preferably, in this embodiment, a first gate electric valve 403 is installed at a position of the surplus grain pipeline 401 near the discharge port of the grain hopper 2, and the quantitative pipeline 402 is connected to the position of the surplus grain pipeline 401 near the first gate electric valve 403;

[0062] A second plug-in electric valve 404 is installed on the quantitative pipeline 402;

[0063] The quantitative pipe 402 extends obliquely downward from one end close to the surplus grain pipe 401 to the end connected to the laboratory.

[0064] In this embodiment, the surplus grain pipeline 401 adopts a stainless steel pipe with a specification of DN150, and the quantitative pipeline 402 adopts a stainless steel pipe with a specification of DN100;

[0065] Based on the specifications of the surplus grain pipeline 401 and the quantitative pipeline 402, the first gate electric valve 403 in this embodiment is DN150; the second gate electric valve 404 is DN100. Both electric gate valves are conventional valve components, driven by electric push rods to open and close the corresponding pipelines. Designing the surplus grain pipeline 401 larger than the quantitative pipeline 402 ensures that the quantitative pipeline 402 can be partially inserted into the surplus grain pipeline 401.

[0066] Preferably, the stirring assembly 3 of this embodiment includes:

[0067] A stirring shaft 301 is rotatably connected to the lower part of the grain hopper 2. The stirring shaft 301 is evenly distributed with stirring blades 302 in the circumference. The stirring blades 302 are made of hard plastic material, preferably a polyurethane scraper; and a rotating component connecting the stirring shaft 301 and the grain hopper 2.

[0068] In order to realize the rotational connection between the stirring shaft 301 and the grain hopper 2, the rotating part of this embodiment includes a fixed plate 303 welded to the grain hopper 2. During welding, the weld interval is 30 mm, the weld width is 20 mm, and the weld height is 4 mm; the bearing seat 304 is assembled and fixed to the fixed plate 303 by tightening bolts, and a bearing 305 is installed in the bearing seat 304. The stirring shaft 301 is rotationally connected to the grain hopper 2 through the bearing 305.

[0069] In order to ensure the normal rotation of the stirring blade 302, the thickness of the lower inner portion of the grain hopper 2 of this embodiment is 200 mm; the width of the stirring blade 302 is 150 mm.

[0070] When the automatic sampling machine begins sampling, stirring blades 302 begin to rotate. As the amount of grain sample entering hopper 2 increases, stirring blades 302 evenly mix the grain sample within hopper 2. When all the grain sample has entered hopper 2, stirring blades 302 continue to rotate for 10 seconds (this rotation time can be adjusted according to actual conditions). Then, the electric valve on the plug-in board is opened to begin releasing the grain. After the grain is released, part of the grain sample enters the quantitative pipe 402 through the connection between the quantitative pipe 402 and the residual grain pipe 401. The position of the second electric valve on the plug-in board 404 is determined in advance based on the actual volume required to ensure that the volume of grain stored in the quantitative pipe 402 meets the test process requirements. When the quantitative value of the stored grain is reached, the second electric valve on the plug-in board 404 opens, and the grain sample flows along the pipe into the laboratory, while the remaining portion enters the residual grain tank 5 through the residual grain pipe 401.

[0071] In the above technical solution, the grain sample stirring and quantitative conveying device provided by the present invention has the following beneficial effects:

[0072] The device of the utility model stirs the grain sample by means of a stirring device integrated in the grain hopper 2, and uses a feeding pipe group to transport the grain sample into the laboratory and the remaining grain box 5 respectively, and realizes quantitative feeding by the cooperation of valves and pipes.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
