[0022] By placing the isolation net 34 at the rear side of the air outlet of the air curtain machine 1, it is possible to prevent the stored grain pests, insect eggs and dust blown from the entrants by the wind force of the air curtain machine 1 from being blown to the rear side of the air curtain machine 1 (i.e., the side of the granary door) and then brought into the granary with the movement of the entrants, thereby improving the safety performance of grain storage in the granary and reducing the possibility of cross-infection of pests; through the cooperation of the suction machine 353, the suction hole 354 and the collection bin 352, the stored grain pests, insect eggs and dust on the entrants are blown out by the wind wall and then transported downward by gravity and the wind force of the wind wall. When it moves to the bottom, it is collected in the collecting bin 352 to prevent stored grain pests, insect eggs and dust from remaining on the ground and entering the granary with the movement of people entering the granary, further improving the safety performance of grain storage in the granary and reducing the possibility of cross-infection of pests; through the setting of the filter 42 and the adsorption layer 43, the gas entering the air curtain machine 1 can be simply filtered to prevent dust, stored grain pests, insect eggs, etc. in the air from entering the air curtain machine 1, which may affect the operation of the air curtain machine 1 and may be blown from the air outlet of the air curtain machine 1 to the people entering the granary, thereby affecting food safety.
[0023] As a possible implementation of the present scheme, preferably, a scraper 311 abutting against the isolation net 34 is fixed to the front side of the bottom of the first mounting seat 31; through the setting of the scraper 311, impurities attached to the surface of the isolation net 34 can be cleaned while the isolation net 34 is rolled up, so as to facilitate the subsequent continuous use of the isolation net 34.
[0024] As a possible implementation mode of the present scheme, preferably, a buffer subassembly 36 is fixedly provided at the bottom of the collecting bin 352 along the length direction; the buffer subassembly 36 includes a buffer plate 361 fixedly provided at the bottom of the collecting bin 352, a buffer base 362 movably sleeved on the outside of the buffer plate 361 along the height direction, and a plurality of return springs 363 provided between the buffer plate 361 and the buffer base 362; through the cooperation of the buffer plate 361, the buffer base 362 and the plurality of return springs 363, the impact force received by the collecting bin 352 when it contacts the ground can be reduced, and the damage caused by multiple collisions of the collecting bin 352 with the ground can be avoided as much as possible, thereby improving the service life of the device.
[0025] As a possible implementation mode of the present scheme, preferably, a collecting box 6 adapted to the length of the filter 42 is detachably provided at the bottom front side of the air curtain machine 1 along the length direction of the air inlet of the air curtain machine 1; when the cleaning plate 54 cleans the filter 42, the impurities cleaned off the filter fall into the collecting box 6 for collection under the action of gravity, thereby preventing the impurities on the filter from falling to the ground as much as possible and then being brought into the granary as the entrants walk.
[0026] As a possible implementation of this solution, preferably, load-bearing plates 7 extending to the outside of the air curtain machine 1 are symmetrically and fixedly arranged on the left and right sides of the front side of the bottom of the air curtain machine 1, and the front end of the upper surface of the load-bearing plate 7 abuts against the collection box body 6; the setting of the load-bearing plate 7 further strengthens the support for the collection box body 6, reduces the possibility of the collection box body 6 falling from the air curtain machine 1, and thus further improves the safety performance of the device during use.
[0027] The working principle of this device is as follows:
[0028] When an operator stands in the detection area of the infrared sensing device 2, the first motor 33 drives the reel 32 to rotate, so that the isolation net 34 gradually winds out from the reel 32 and extends downward under the action of gravity until the bottom of the collection bin 352 abuts against the ground. Subsequently, the air curtain machine 1 starts to operate, and airflows are blown downward from the air outlet to form a uniform air wall to clean the stored grain pests, eggs and dust on the body of the person entering the bin. At the same time, the suction machine 353 is turned on. When the stored grain pests, eggs and dust on the body of the person entering the bin are blown out by the air wall and move downward under the action of gravity and the wind force of the air wall to the bottom, the suction machine 353 collects the stored grain pests, eggs and dust into the collection bin 352 through the suction holes 354. When the body of the person entering the bin is cleaned, the air curtain machine 1 and the suction machine 353 stop working. Subsequently, the first motor 33 drives the reel 32 to rotate in the reverse direction, and the isolation net 34 can be gradually wound around the reel 32; when the filter screen needs to be cleaned, the second motor 53 drives the screw rod 52 to rotate, so that the cleaning plate 54 moves horizontally along the filter screen 42 to realize the cleaning of the filter screen 42.
[0029] The above is only the specific implementation manner of the present invention, and it does not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
