Example 2:

in order to facilitate understanding of the present invention, a complete process of peeling, drying and collecting small insects by a small insect treatment system including the present invention will be described in detail.

A treatment system for small insects comprises an insect peeling device for peeling insects and a treatment system for drying the small insects, wherein the treatment system is arranged in an engagement mode, the insect peeling device comprises a blade conveying mechanism 2 for conveying blades and a layering transmission mechanism 3 which is arranged in a synchronous transmission mode, and the layering transmission mechanism 3 is oppositely arranged above the blade conveying mechanism 2; as shown in fig. 1 and 2, in the present embodiment, the blade conveying mechanism 2 includes a frame and a conveying belt mounted on the frame, and the bead driving mechanism 3 includes driving chains mounted on both sides of the frame in the width direction.

Above the blade conveyor 2 there is also a stripping drum 4, which stripping drum 4 is located between the two drive chains, as can be seen in the figure, in the middle of the chain drive path.

The bristles of the stripping roller 4 are in contact with the upper surface of the blade conveying mechanism 2; install a plurality of layering mechanisms on the layering drive mechanism 3, layering mechanism includes layering 11, the both ends tip of layering 11 is provided with erection support 12, erection support 12 is including the undersetting 13 that is used for connecting layering 11 and the upper bracket 14 that is used for installing fixedly, be connected with telescopic elastic component 15 between undersetting 13 and the upper bracket 14. The layering mechanism is arranged on a transmission chain of the layering transmission mechanism 3 through the upper support 14, rotates along with the transmission chain, and can be in pressure joint with the upper surface of the blade conveying mechanism 2.

When the leaf blade stripping device is used, the upper support is installed on the insect stripping device, the upper support is connected with the lower support and the pressing strip through the elastic component, and therefore the two ends of the pressing strip are provided with the elastic components which can stretch, when the leaf blade is pressed and fixed, the pressing strip is firstly contacted with the veins with the largest thickness, and the elastic components at the two ends of the pressing strip are contracted and deformed under the reaction force of the veins. Meanwhile, the elastic parts at the two ends use the position of the vane as a fulcrum, so that the pressing strip inclines towards the side where the elastic part is located, which is relatively far away from the vane, thereby pressing more vanes at the side and achieving a good pressing and fixing effect. In addition, due to the contraction of the elastic component, the reaction force borne by the pressing strip is reduced, the deformation quantity of the pressing strip is weakened, and the pressing strip can be prevented from deforming early in the using process, so that the service life of the pressing strip is prolonged.

In practice, the bead 11 is made of a flexible elastic rod.

In this way, the batten bends towards two sides by taking the position of the thickest vein as the center under the pressure of the elastic parts at two sides, so that the lower blade can be pressed and fixed as much as possible.

As shown in fig. 4 and 5, the middle of the pressing strip 11 has a bent portion in a shape of a Chinese character ji.

Therefore, once the pressing strip deforms under the reaction force of the veins, the preset bending part on the pressing strip can absorb partial deformation force, the deformation of the pressing strip is reduced, and once the reaction force disappears, the pressing strip can be quickly restored to the original shape.

In practice, the dividing strips 16 are made of elastic steel wires.

Therefore, the deformable amount of the partial pressure strips can be increased, and the blades can be more reliably pressed and fixed by utilizing the elasticity of the partial pressure strips.

In implementation, the partial pressure strips 16 are integrally bent into an arc shape, and the pressing part is located in the middle of the partial pressure strips 16.

Therefore, the contact part of the sub-dividing pressing strip and the blade is arc-shaped, and the blade is prevented from being damaged by the end part of the sub-dividing pressing strip. Meanwhile, the contact area between the arc-shaped partial pressing strip and the blade can be smaller, so that the partial pressing strip is prevented from pressing or crushing insects.

During specific implementation, the layering 11 is rotatably sleeved with a plurality of lantern rings arranged at intervals, the layering 16 is arranged on the lantern rings, and an elastic mechanism used for enabling the layering 16 to rotate towards the pressing and fixing direction is arranged between the lantern rings and the layering. Therefore, the lantern ring can rotate reversely by the reaction force of the blades acting on the partial pressure strips, so that the deformation of the partial pressure strips is reduced under the condition that the pressure fixing force is not weakened, and the service life of the partial pressure strips is prolonged.

Specifically, elastic mechanism can be the cover and establish torsional spring on the layering 11, also can be two magnets that set up along the circumference syntropy of layering 11 relatively, have on the inner wall of the lantern ring or the layering along the recess that circumference set up, two magnet is located in the recess, and respectively with lantern ring and layering 11 fixed connection.
