Description

Technical Field

[0001] This utility model relates to the field of grain sampling technology, specifically a mobile sampling device for grain silos. Background Technology

[0002] With the development of the times, people's methods of grain storage are becoming more and more advanced. Silos occupy little space, have a large storage capacity, and are highly mechanized, so they have become the main method of grain storage. When grain enters or leaves the silo, it is necessary to inspect the quality of the grain. In particular, when the grain is cleaned and put into storage, it is even more necessary to accurately grasp the quality of the grain entering the silo. Therefore, it is necessary to take samples and check the grain during the transportation process. Thus, a mobile sampling device for grain silos is needed.

[0003] Existing methods for sampling grain silos typically employ specialized sampling tools, such as the grain testing sampling device disclosed in Chinese patent CN202321001729.1 (application date: April 27, 2023). These devices require workers to manually hold the sampling tool for extraction. To improve testing accuracy, multiple samplings are often necessary, significantly increasing the workload for workers using traditional manual sampling tools. Utility Model Content

[0004] The technical problem this invention aims to solve is that in the prior art, sampling and inspecting grain in grain silos requires handheld sampling tools, involves numerous samplings, and results in high workload and low efficiency for staff.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0006] A mobile sampling device for grain silos includes a base plate. A sampling component and an auxiliary component are mounted on the top of the base plate. The sampling component includes a support frame fixedly connected to the top of the base plate, with a sample storage container fixedly connected inside the support frame. A power compartment is fixedly connected to the top of the sample storage container. A mesh screen is installed on the lower side of the power compartment, and an exhaust fan is installed on the upper side. A conveying hose is fixedly connected to the side surface of the sample storage container, and a flow meter is connected to the conveying hose. A sampling tube is installed at the other end of the conveying hose. The auxiliary component controls the sampling frequency of the sampling component.

[0007] Optionally, the sampling assembly further includes a fixing member, which is fixedly connected to the top of the support frame, and the fixing member has a fixing bolt connected to its internal thread.

[0008] Optionally, the auxiliary component includes a power supply compartment, which is fixedly connected to the top of the device base plate, a control console is fixedly connected to one side of the power supply compartment, and a heat dissipation mesh is fixedly connected to the back of the power supply compartment; the auxiliary component also includes a control panel, which is fixedly connected to the top of the control console, a connecting wire is fixedly connected to one side of the power supply compartment, and the other end of the connecting wire is fixedly connected to one side of the power compartment.

[0009] Optionally, one end of the sampling tube is fixedly connected to a handle, and a through hole is provided on the side surface of the sampling tube.

[0010] Optionally, the bottom of the device base plate is fixedly connected to casters, and the top of the device base plate is fixedly connected to a movable push rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, by installing a sampling component, a sampling tube can be inserted into the grain channel of the grain silo. Then, the exhaust fan in the power compartment is turned on, so that the grain can be drawn into the sample storage bucket through the conveying hose. During the extraction process, the flow meter can record the amount of grain extracted. After the extraction is completed, the staff can open the bottom channel of the sample storage bucket to take out the sample, thereby reducing the workload of the staff in sampling.

[0013] In this invention, by installing auxiliary components, the power supply compartment can provide power to the entire device. The operator can use the control panel connected to the exhaust fan to perform sampling operations. Then, the operator can use the charging port at the back of the power supply compartment to charge the internal battery, so that the battery power can be supplied to the power compartment through the connecting wire, thereby improving the practicality.

[0023] By installing sampling component 2, sampling tube 208 can be inserted into the grain channel of the grain silo. Then, the induced draft fan 205 in the power compartment 203 is started. The fan provides sufficient power to create a negative pressure environment inside the sample storage container 202, allowing the grain to be drawn into the sample storage container 202 through the delivery hose 206. During the extraction process, flow meter 207 records the amount of grain extracted. After extraction is completed, the staff can open the bottom channel of the sample storage container 202 to remove the sample.

A connecting wire 305 is fixedly connected to one side of the power supply compartment 301, and the other end of the connecting wire 305 is fixedly connected to one side of the power compartment 203.

[0025] By installing auxiliary component 3, the power supply compartment 301 can provide power to the entire device. The operator can use the control panel 304, which is electrically connected to the blower 205, to start and stop the power compartment 203, thereby controlling the sampling component 2 to perform sampling work, including the number of samplings and the sampling interval. The operator can use the charging port at the rear of the power supply compartment 301 to charge the internal battery, so that the battery power can be supplied to the power compartment 203 through the connecting wire 305.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a handle 4 is fixedly connected to one end of the sampling tube 208, and a through hole 5 is provided on the side surface of the sampling tube 208; the handle 4 facilitates insertion or removal of the tube 208, and the through hole 5 facilitates unblocking when the tube 208 becomes blocked.

[0030] Insert the sampling tube 208 into the grain channel of the grain silo; then start the induced draft fan 205 in the power chamber 203 so that the grain can be drawn into the sample storage bucket 202 through the conveying hose 206, and the flow meter 207 measures the grain drawn during the extraction process; then, after the extraction is completed, the staff can open the bottom channel of the sample storage bucket 202 to take out the sample.

[0031] This invention achieves sampling by installing a sampling component to automatically collect samples at regular intervals and in quantitative quantities, eliminating the need for staff to repeatedly manually retrieve samples and reducing the workload of sampling personnel.

[0032] This device is equipped with an integrated power supply and control unit. Operators can charge the internal battery using the charging port at the rear of the power compartment, so that the battery power can be supplied to the power compartment through the connecting wire, thereby improving its practicality.
