Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to an insect pest gas detector used in a granary. Background Art

[0002] Grain storage refers to the process of storage and management of grain from harvest to consumption. When the water content is low (below 12.5%) and the ambient temperature is low (below 15-20°C), the respiration intensity is weak, but it can maintain minimum life activities, which is beneficial to storage. Currently, there are generally two storage methods: conventional sealed storage and underground storage.

[0003] At present, after storing grain in granaries for a period of time, pests, grain spoilage and harmful gases often occur. However, the current situation in the granaries is generally inspected and monitored by personnel. This method cannot monitor the situation in the granaries in real time, which increases the probability of various situations such as pests and grain spoilage, and reduces the effective storage rate of the granaries. Utility Model Content

[0004] In order to solve the problem in the above background technology that the situation in the granary cannot be monitored in time, the purpose of the utility model is to provide an insect pest gas detector for a granary.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an insect pest gas detector for a granary, comprising a cabinet body and a cabinet door, the cabinet door is cooperatively mounted on the cabinet body, an exhaust pipe mounting plate is cooperatively mounted in the cabinet body, a plurality of air pipe solenoid valves are cooperatively mounted in the cabinet body, a plurality of exhaust pipes are mounted on the exhaust pipe mounting plate, each of the exhaust pipes is connected to a corresponding air pipe solenoid valve pipe, an insect counter is cooperatively mounted in the cabinet body, and the air pipe solenoid valve is connected to the insect counter pipe;

[0006] An insect collecting bottle is installed in the cabinet, and the insect counter is connected to the insect collecting bottle tube. A gas detector with several tubes connected in series is installed in the cabinet, and the insect collecting bottle is connected to the gas detector tube. An air release valve is installed in the cabinet, and the gas detector is connected to the air release valve tube.

[0007] Preferably, a PLC controller is installed in the cabinet, a main junction box and a plurality of air switches are installed in the cabinet, and a control panel is installed in the cabinet.

[0008] Preferably, the harmful gas monitoring substances of the gas detectors are different.

[0009] Preferably, the insect collecting bottle comprises a bottle body and a bottle cap, and the bottle cap is mounted in cooperation with the bottle body.

[0010] Preferably, an air inlet interface and an air outlet interface are installed on the bottle cap, an insect collecting cavity is opened in the bottle cap, the air inlet interface is connected with the insect collecting cavity through a gas channel, the upper end of the insect collecting cavity is connected with the air outlet interface, and an insect outlet tube is installed at the lower end of the insect collecting cavity.

[0011] Preferably, a pneumatic filter is installed at the lower end of the air outlet interface, and the pneumatic filter is located in the insect collecting cavity. A plurality of insect sticking plates arranged in a linear array are installed in the bottle body, and the insect sticking plates are coated with insect sticky glue.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model can monitor common harmful gases in various granaries through gas monitors, and can also monitor the number of insects in the gas collected in the granary through insect counters. The insect collector can collect the collected insects, so that the inspectors can observe more clearly, thereby improving the work efficiency of the inspectors. According to the collected information, the granary can be adjusted and maintained in a targeted manner, thereby improving the effective storage rate of the granary;

[0014] When the insect collecting bottle of the present invention is in use, the gas containing insects enters the gas channel through the air inlet interface (the gas forms intermittent pulses through the corresponding solenoid valve), and the gas containing insects then moves toward the pneumatic filter element through the bent gas channel. When the gas containing insects passes through the pneumatic filter element, the filtered gas can be discharged into the gas detector through the air outlet interface, and the filtered insects fall into the bottle body 1111 through the insect outlet pipe 1115 after the pulse gas ends. This prevents the insects from clogging the starting filter element used for filtering, and also prevents the gas containing insects from being filled into the insect collecting bottle and causing the insects to collide with each other, thereby further improving the service life of the insect collecting bottle.

[0026] An insect collecting bottle 111 is installed in the cabinet 101, and the insect counter 110 is connected to the insect collecting bottle 111 through a pipe. A plurality of gas detectors 108 connected in series are installed in the cabinet 101, and the insect collecting bottle 111 is connected to the gas detector 108 through a pipe. An air relief valve 112 is installed in the cabinet 101, and the gas detector 108 is connected to the air relief valve 112 through a pipe. A PLC controller 104 is installed in the cabinet 101, a main junction box 105 and a plurality of air switches 106 are installed in the cabinet 101, and a control panel 103 is installed in the cabinet 101.

[0027] Further, referring to an embodiment of the utility model, the air outlet of the air relief valve 112 faces the PLC controller 104, and the gas blown out by the air relief valve 112 cools the PLC controller 104 to prevent the PLC controller 104 from heating up and causing it to lose steps or misalign. When the present application is in use, a plurality of air extraction pipes are installed on the air extraction pipe mounting plate 109. The number of air extraction pipes is the same as the number of solenoid valves and they are arranged one by one. One end of the air extraction pipe is connected to the corresponding solenoid valve, and the other end of the air extraction pipe is installed in the corresponding granary for collecting the gas in the granary. The present application also includes a vacuum pump station, which is used to provide vacuum adsorption force. The vacuum pump station is installed on the rear side of the cabinet 101, and the vacuum pump station is conventional technology and is not drawn in the figure.

[0028] The harmful gas monitoring substances of the gas detector 108 are different. Furthermore, referring to an embodiment of the utility model, the number of gas detectors 108 is three, which are used to monitor carbon monoxide, ammonia and carbon dioxide respectively. Carbon monoxide is colorless and odorless, and can cause hypoxia and poisoning of patrol personnel; when grain is damp or moldy, ammonia is released, and high concentrations of ammonia can irritate and damage the respiratory system; when stored grain respires, a large amount of carbon dioxide is produced, and high concentrations of carbon dioxide can cause suffocation and death.

[0029] The insect collecting bottle 111 includes a bottle body 1111 and a bottle cap 1112, and the bottle cap 1112 is installed in cooperation with the bottle body 1111, and an air inlet interface 1116 and an air outlet interface 1117 are installed on the bottle cap 1112. An insect collecting cavity 1113 is opened in the bottle cap 1112, and the air inlet interface 1116 is connected with the insect collecting cavity 1113 through a gas channel 1114. The upper end of the insect collecting cavity 1113 is connected with the air outlet interface 1117, and the lower end of the insect collecting cavity 1113 is installed with an insect outlet pipe 1115.

[0030] A pneumatic filter element 1119 is installed at the lower end of the air outlet interface 1117, and the pneumatic filter element 1119 is located in the insect collecting chamber 1113. A plurality of insect sticking plates 1118 arranged in a linear array are installed in the bottle body 1111, and the insect sticking plates 1118 are coated with insect sticky glue.

[0031] Further, referring to an embodiment of the utility model, when the insect collecting bottle 111 is in use, the gas containing insects enters the gas channel 1114 through the air inlet interface 1116 (the gas forms intermittent pulses through the corresponding solenoid valve), and the gas containing insects then moves toward the pneumatic filter element 1119 through the bent gas channel 1114. When the gas containing insects passes through the pneumatic filter element 1119, the filtered gas can be discharged into the gas detector 108 through the air outlet interface 1117. After the pulse gas ends, the filtered insects fall into the bottle body 1111 through the insect outlet pipe 1115. This prevents insects from clogging the starting filter element used for filtering, and also prevents the gas containing insects from being filled into the insect collecting bottle 111 and impacting the insects to the point of causing them to collide with each other.

[0032] It should be noted that the utility model can monitor common harmful gases in various granaries through gas monitors, and can also monitor the number of insects in the gas collected in the granary through insect counters 110. The insect collector can collect the collected insects, so that the inspectors can observe more clearly, thereby improving the work efficiency of the inspectors. According to the collected information, the granary can be adjusted and maintained in a targeted manner, thereby improving the effective storage rate of the granary. When the insect collecting bottle 111 is in use, the gas with insects enters the gas channel 1114 through the air inlet interface 1116 (the gas passes through the corresponding solenoid valve shape The gas containing insects then moves toward the pneumatic filter element 1119 through the bent gas channel 1114. When the gas containing insects passes through the pneumatic filter element 1119, the filtered gas can be discharged into the gas detector 108 through the gas outlet interface 1117. After the pulse gas ends, the filtered insects fall into the bottle body 1111 through the insect outlet pipe 1115. This prevents insects from clogging the starting filter element used for filtration, and also prevents the gas containing insects from being filled into the insect collecting bottle 111 and causing the insects to crash around. This further increases the service life of the insect collecting bottle 111 and reduces the probability of various situations such as insect pests and food spoilage.
