Description

Technical Field

[0001] The invention relates to the technical field of insect screening, in particular to a device for screening small flower stink bugs. Background Art

[0002] The small flower stink bug belongs to the order Hemiptera, the family Anthopodidae, and is an important class of predatory natural enemy insects. It can prey on adults, larvae and eggs of pests such as thrips, whiteflies, spider mites, aphids, etc., and is particularly suitable for preventing and controlling thrips pests. It can play an important role in the pest control of facility vegetables. The application of natural enemy insects in agricultural production requires the ability to raise small flower stink bugs on a large scale and make products. After the small flower stink bugs are cultivated on a large scale, they are often mixed with the cultivation matrix (such as wheat). It is necessary to remove the matrix, separate the small flower stink bugs, and package them into products.

Beneficial Effects

[0014] The present invention provides a device for screening small flower bugs. Compared with the prior art, the device has the following beneficial effects: (1) By setting up an automatic punching and shaking-off mechanism, the driving assembly is used to drive the punching rod to lift up, and then the punching and vibrating screen is performed, so that the small flower bugs adsorbed on the screen due to static electricity during the screening process are shaken off and fall into the insect collecting trough, thereby avoiding the blockage of the screen and allowing the screening process to proceed normally.

[0031] Based on Example 2, see Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, a screening unit 8 for driving the screen 2 to perform screening operations is provided on the mounting frame 1. The screening unit 8 is rotatably connected to four swing arms 81 through a pin shaft.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] During operation, a mixture of small flower stink bugs and cultivation substrate is poured into the hopper 4, and then the motor 64 is started, so that the motor 64 drives the screw rod 63 to rotate, and then the screw rod 63 drives the moving seat 61 to move upward, and then the convex column 62 on the moving seat 61 drives the trapezoidal block 59, the sliding seat 54, the connecting rod 71, and the rack 72 to move upward, and at the same time, the compression spring 56 is squeezed, and the rack 72 drives the gear 75 and the rotating rod 74 to rotate.

When the connecting column 510 on the trapezoidal block 59 contacts the baffle 514, the baffle 514 drives the connecting column 510 and the trapezoidal block 59 to move left, driving the trapezoidal The block 59 slides into the transverse groove 58, and at the same time squeezes the compression spring 2 512, so that the protrusion 62 is separated from the trapezoidal block 59. At this time, the spring 1 56 in the compressed state drives the slide seat 54 and the punch rod 57 to punch downward, and at the same time drives the rack 72 to move downward, so that the fan blade 79 rotates clockwise. At this time, the blowing angle is obliquely downward. By changing the blowing angle, the mixture is evenly blown at various places near and far of the screen 2, the motor 1 64 is turned off, and the motor 2 82 is started, so that the motor 2 82 drives the screen 2 to swing left and right and up and down, the mixture is screened, and then the small flower stink bugs are screened into the insect collecting groove 9, and the motor 1 64 is started again to realize the punching of the punch rod 57 on the screen 2, so that the screen 2 vibrates and shakes off the small flower stink bugs adsorbed by static electricity in the screen 2, and further starts the LED insect sucking lamp 11, so that the small flower stink bugs are attracted by the light and automatically crawl out of the insect outlet bucket 10 and fall into the insect collecting box 13 for collection.

[0036] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention.
