[0023] The utility model will be further described below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] refer to Figures 1 to 3 , an automatic trapping monitoring system in a granary, which includes an automatic trapping monitoring device in a granary, an air pump 5 and a filtering device 6.

[0026] like Figure 1 and Figure 3 The filter device 6 comprises a device body 61 and a filter part 62 arranged in the device body 61. The filter part 6 adopts multi-layer filter gauze or filter cotton, and the diameter of the filter hole is preferably 1 to 2 mm, and it is required to satisfy the requirement of being able to pass gas but not pass pests. The filter part 62 divides the inner cavity of the device body 61 into an insect collecting cavity 63 and an air outlet cavity 64, the insect collecting cavity 63 is connected to an air inlet pipe 65, and the air outlet cavity 64 is connected to an air outlet pipe 66, and the end of the air outlet pipe 66 is connected to the air extraction end of the air extraction pump 5.

[0027] like Figure 1 and Figure 2 The automatic trapping monitoring device in the granary includes a trap, which has a cylindrical shell 1 with an opening at the top, a top cover 11 is provided on the top opening of the cylindrical shell 1, and the bottom is an inverted cone shell structure. The upper part of the side wall of the cylindrical shell 1 has a light trapping hole 15. In addition, the upper part of the side wall of the cylindrical shell 1 has two symmetrically arranged handles 12, and the side wall has a plurality of insect holes 13 below the handles 12. The bottom end of the cylindrical shell 1 has an air suction hole and is connected to an air suction pipe 14. The cylindrical shell 1 is provided with a trap placement part 2, and the trap placement part 2 is located in the lower part of the cylindrical shell 1 and has a gap with a width d of at least 1 cm with the inner wall of the cylindrical shell 1. The purpose of the gap is that when the pests are sucked, the pests can pass through the gap with the air flow. The end of the air suction pipe 14 of the trap is connected to the air inlet pipe 65 of the filter device 6.

[0028] When the automatic trapping monitoring system in the granary of this embodiment is used, before the grain is put into the granary, the automatic trapping monitoring device in the granary and the related air pipes for connection are pre-buried in the granary, and the pre-buried height is such that the handle 12 is exposed from the grain surface, and the worm holes 13 are all located below the grain surface. The vacuum pump 5 and the filter device 6 are placed outside the granary. After the grain is put into the granary, when it is necessary to monitor the pests in the grain pile, the trap 9 is first placed in the trap placement part 2, and then the top cover 11 is opened, and then the trap placement part 2 is placed in the trap. Once pests appear in the grain pile, the pests in the grain pile are attracted by the trap 9 and drill into the trap through the worm holes 13. After trapping for a period of time, the vacuum pump 5 is turned on from outside the warehouse, and the vacuum pump 5 generates a vacuum airflow. The trapped pests in the trap are moved along the vacuum airflow from the inside of the trap → vacuum pipe 14 → air inlet pipe 65 → filter device 6 → insect collecting chamber 63. Under the filtering and isolating effect of the filter part 62, the pests are sucked and collected in the insect collecting chamber 63, and the vacuum airflow that has filtered out the pests continues along the air outlet chamber 64 → air outlet pipe 66 → vacuum pump 5, and is discharged from the exhaust end of the vacuum pump 5.

[0029] like Figure 3 Furthermore, the device body 61 of the filtering device 6 is a cylindrical structure, and a detachable shell cover 611 is connected to each of its two ends, and the filtering part 62 is arranged between the two shell covers 611 in the device body 61. The detachable shell cover 611 can provide convenience for cleaning the inside of the filtering device 6, and for taking out the pests accumulated in the filtering device 6 for inspection. Furthermore, in order to facilitate the installation and removal of the shell cover 611, the two ends of the device body 61 are connected to the two shell covers 611 by threaded connection.

[0030] like Figure 2Furthermore, the trapping agent placement part 2 adopts a bag-like structure or a disc-like structure, and is suspended in the cylindrical shell 1 by a hanging rope 20. The middle part of the top cover 11 in the cylindrical shell 1 has a hanging ring 10, and the end of the hanging rope 20 has a hook 21 and is hooked on the hanging ring 10. Through the cooperation of the hanging rope 20, the hook 21, and the hanging ring 10, the trapping agent placement part 2 can be positioned and placed in the trap very conveniently, efficiently, and at a low cost, and the trapping agent 9 can be conveniently replaced.

[0031] Example 2

[0032] refer to Figures 4 to 6 The difference between the automatic trapping monitoring device in the granary of this embodiment and the embodiment 1 is that: this embodiment also includes an outer sleeve 3, which is a cylindrical shell structure with a top opening at the top and a bottom shell portion 31 with an inverted cone shell structure at the bottom. The side wall of the outer sleeve 3 has a plurality of vertically arranged long strip side openings 32, so that the side wall of the outer sleeve 3 has a fence-like structure. The purpose of the side wall of the outer sleeve 3 with a fence-like structure is to avoid blocking the insect holes 13 of the trap and to make the outer sleeve 3 have sufficient strength.

[0033] The outer sleeve 3 is coaxially sleeved on the outside of the cylindrical shell 1 of the trap and is correspondingly located below the two handles 12. A pipe cavity 30 is formed between the outer sleeve 3 and the outer wall of the cylindrical shell 1. The exhaust pipe 14 is arranged along the pipe cavity 30 and its end passes through the top of the outer sleeve 3.

[0034] When in use, the automatic trapping monitoring device in the granary and the related air pipes for connection can be pre-buried in the granary before the grain is put in, and the air pump 5 and the filter device 6 are placed outside the granary. After the grain is put in, the bottom shell part 31 of the outer sleeve 3 is in an inverted cone structure, and the trap is inserted into the grain pile together with the air extraction pipe 14. The end of the air extraction pipe 14 is located on the grain surface and is connected to the filter device 6 outside the granary through a pipeline. This embodiment realizes the quick and convenient use of the automatic trapping monitoring device in the granary, so that the storage personnel can place it according to the situation in the granary and the monitoring needs after the grain is put in.

[0035] like Figure 6 Furthermore, an annular sealing plate portion 33 is provided between the top opening of the outer sleeve 3 and the outer wall of the cylindrical shell 1, and a sealing plate through-hole 34 is provided on the annular sealing plate portion 33. The exhaust pipe 14 passes through the sealing plate through-hole 34 and goes out of the outer sleeve 3, and the force bearing capacity of the outer sleeve 3 is strengthened by the annular sealing plate portion 33.

[0036] like Figures 4 to 6Further, the bottom of the handle 12 has a transverse portion 121 disposed close to the outer sleeve 3, the top of the outer sleeve 3 has two symmetrical top through holes 35 corresponding to the two transverse portions 121 of the handle 12, and the transverse portion 121 of the handle 12 has a handle connecting hole 122 corresponding to the top through holes 35, and the outer sleeve 3 is fastened to the handle 12 through the top through holes 35, the handle connecting hole 122 and the connecting bolt 4. In the above structure, the outer sleeve 3 is fastened to the trap by the handle 12, which has the characteristics of simple structure and fast connection.
