Detailed ways:

The present invention is described further below with specific embodiment, referring to Fig. 1-14:

A kind of automatic grain detection experimental comprehensive machine, comprises frame 1, and the grain sample dividing device 2 that is arranged on frame 1, the feed inlet of described grain sample divider 2 is used for receiving the grain to be detected, the discharge port There are several, wherein three of the outlets of the grain sampling device 2 are respectively communicated with the automatic bagging device 3, the bulk density and the impurity detection device 5 and the feed inlet of the moisture detection device, and the grain sampling device 2 can respectively send The automatic bagging device 3, the bulk density and impurity detection device 5 and the moisture detection device deliver quantitative grains to be detected; the automatic bagging device 3 can package the received grains to be detected, and the bulk density and impurity detection device 5 can detect The received grains to be detected are weighed, filtered, and re-weighed in order to obtain the grain density ratio and the grain impurity rate. The moisture detection device can perform moisture detection on the received grains to be detected to obtain the grain moisture content. Among them, the present invention is not limited to the automatic bagging device 3, the bulk density and impurity detection device 5, and the moisture detection device, that is, the present invention can also be equipped with other detection item equipment in the future. Correspondingly, only the grain sampling device 2 needs to be added The discharge port enables the grain sampling device 2 to deliver a quantitative amount of grain to be detected to the subsequent additional detection item equipment.

The present invention only needs to put the grains to be detected into the grain sampling device 2, and carry out quantitative sampling from the grains to be detected through the grain sampling device 2, so that the automatic bagging device 3, the bulk density and impurity detection device 5 and the moisture detection The devices can obtain the grains to be detected with the required specified capacity, and the automatic bagging device 3 can package the received grains to be detected to form packaging bags for storage, and the bulk density and impurity detection device 5 can check the received grains to be detected. Detect the grains to be weighed, filtered, and re-weighed to obtain the grain bulk density rate and grain impurity rate. The moisture detection device can perform moisture detection on the received grains to be detected to obtain the grain moisture content. It has a high degree of automation. No need for manual inspection, less workload and fast detection efficiency.

And described grain sampling device 2 comprises the material feeding main container 201 that is located on the frame 1, the bottom of material feeding main container 201 is provided with several sorting ports, is provided with and sorting port one by one on the frame 1. Corresponding to the quantitative container 202, the feed port of the quantitative container 202 corresponds to the position of the corresponding sorting port, and there is an overflow gap between the two, and the frame 1 is provided with a shelf for accepting the grains to be detected overflowing from the overflow gap. Recovery container 203, wherein, in the present embodiment, the capacity of each quantitative container 202 is the same, and because automatic bagging device 3, bulk density and impurity detection device 5 and moisture detection device are equipped, so sorting port only offers three , the specific number can be determined according to the actual number of devices configured in this equipment. Of course, the capacity of each quantitative container 202 can also be different, and it should be determined according to the specified capacity required for actual detection or other purposes; in addition, the recovery container 203 can quickly recycle the redundant grains to be detected, avoiding the grains to be detected. waste, and, in order to facilitate the collection of the grains to be detected in each recovery container 203, the discharge port of each recovery container 203 is communicated with the main grain recovery container 8. In this embodiment, each recovery container 203 The discharge port of each is communicated with the feed inlet of the material return funnel one 211, and the discharge port of the material return funnel one 211 is communicated with the grain recovery main container 8 by pipeline.

The grain to be detected is placed in the main feeding container 201, and the grains to be detected are respectively put into the corresponding quantitative container 202 with a designated capacity from a plurality of sorting ports, and until the quantitative container 202 is filled, the excess grain to be detected It will fall into the recovery container 203 through the overflow gap, thereby completing the quantitative measurement of multiple portions of the grain to be detected. The overall structure is simple, time-saving and labor-saving, and the efficiency is high.

And the quantitative container 202 is movably connected with the quantitative valve plate 210 driven by the corresponding power source and can block or conduct the quantitative container 202 discharge port. The quantitative container 202 is filled up and the grain to be detected has been removed from the feeding main container. When all the grains in 201 are discharged, the quantitative valve plate 210 leads to the discharge port of the quantitative container 202, so that the quantitative grains to be detected can enter the subsequent corresponding devices respectively. And the specific connection structure and driving mode of the quantitative valve plate 210 can adopt the existing common structure, and in the present embodiment, the specific connection structure and the driving mode of the quantitative valve plate 210: the quantitative valve plate 210 is hinged on the quantitative container 202, quantitative The valve plate 210 is in transmission connection with the valve power source provided on the frame 1 , and the valve power source drives the rotation of the quantitative valve plate 210 to realize the blocking or conduction of the discharge port of the quantitative container 202 .

Therefore, in order to ensure that the quantitative measurement of the grains to be detected is accurate, the frame 1 is provided with a function that can be carried out in the overflow gap. The push pedal 207 that moves, the push pedal 207 is connected with the quantitative driving source transmission that is arranged on the frame 1, drives the push pedal 207 to move in the overflow gap by the driving source, so that the to-be-treated material that is piled up on the outside of the feed port of the quantitative container 202 The detected grain is pushed into the recycling container 203 .

Among them, the push plate 207 can push the redundant grains to be detected outside the feed port of the quantitative container 202 into the recovery container 203 in a horizontal sliding manner, but correspondingly, the driving source required for the driving movement of several push plates 207 A corresponding quantity is needed, and the cost is relatively large. Therefore, in this embodiment, in order to reduce the number of parts and reduce the cost, the horizontal height of the feed inlet of the quantitative container 202 is greater than or equal to the horizontal height of the feed inlet of the recovery container 203.
