Example 1
 Please refer to figure 1 , figure 1 This is a structural diagram of the multi-tray insect breeding device 100 provided by the present invention. Such as figure 1 As shown, the device includes a metal frame 110 and at least two breeding boxes 120.
 The same side surface of the body of all breeding boxes 120 has a first opening, the edge of the first opening is hingedly provided with a cover, and a locking part is provided between the cover and the main body for firmly buckling the cover on the main body. As an example, figure 1 In the culture device shown, the entire left side of the five culture boxes 120 forms a first opening, and the upper edge of the first opening is hingedly provided with a cover 1220.
 As a preferred embodiment, the three sides of the body of the culture box 120 are all transparent acrylic plates, and the bottom of the body is a PP plate. The cover 1220 is a transparent acrylic plate. The upper side of the breeding box is hollowed out to form a second opening. The space between the upper and lower breeding boxes can be used for operations such as feeding, cleaning and disinfection, and artificial insect throwing. As an example, the three sides of the body and the cover are all made of transparent acrylic sheet with a thickness of 2-3mm, and the bottom adopts a gray PP sheet with a thickness of 3-5mm. At the same time, the bottom is welded with 2-3 reinforcing ribs to increase the load-bearing capacity of the bottom of the box. The stability.
 As a preferred embodiment, the ratio between the distance between adjacent culture boxes 120 and the height of the culture boxes is 1.2-2. As an example, the height of the culture box 120 is 20 cm, and the distance between the culture boxes is 25 cm.
 The metal frame 110 is fixedly connected to the main body of the breeding box 120 so that the breeding boxes are aligned along the height direction of the metal frame 110. Specifically, the shape of the culture box 120 is a cube or a cube. As an example, figure 1 The culture device shown is equipped with five culture boxes, which are cubes. Understandably, the breeding device can be equipped with six or other number of breeding boxes.
 As an embodiment, the metal frame 110 is made of angle steel sprayed with plastic.
 The breeding box with a cover can be easily opened from the side during unloading, overall cleaning and disinfection, which is more convenient than unloading, cleaning and disinfecting from the top of the breeding box.
 Preferably, the lids 1220 of all breeding boxes 120 are opened and closed by the linkage mechanism 130, and these lids and the linkage mechanism 130 together form a linkage lid. Such as Figure 1-5 As shown, the linkage mechanism 130 includes linkage rods 1320 arranged at the edges of both sides of the cover 1220 and a plurality of reinforcement rods 1310 arranged between the two linkage rods 1320. Preferably, the number of reinforcing rods 1310 is the same as the number of the breeding box 120, and when the linkage cover is closed (such as Figure 1-3 (Shown), the reinforcing rod 1310 is located on the center line of the cover 1220. The two lower end sides of each cover 1220 are respectively fixedly connected with the corresponding linkage rod 1320 through the connecting piece 1221.
 When it is necessary to open the lid, unlock the locking part 140, and then manually pull the linkage rod 1320 to rotate, so that the linkage rod 1320 simultaneously drives the lids 1220 of all breeding boxes to open. The open state is as follows: Figure 4 with 5 Shown.
 Such as figure 2 with 3 As shown, the linkage rod 1320 is an integrally formed metal rod similar to an angle steel, which includes a first side plate 1321 and a second side plate 1322 that are perpendicular to each other. The first side plate 1321 is fixedly connected to the cover 1220 through a connecting piece 1221, such as Figure 4 Shown. Such as Figure 1-3 As shown, in the locked state, the second side plate 1322 is attached to the vertical side wall of the metal frame 110.
 Such as figure 1 As shown, the cultivating device includes two symmetrically arranged locking parts 140 for locking two linkage rods 1320 and the corresponding metal frame 110 respectively. Such as image 3 As shown, the locking portion 140 is provided with a U-shaped locking groove 1410. In the locked state, one groove wall of the engaging groove 1410 is attached to the side of the vertical side wall of the metal frame away from the linkage mechanism 130, and the other groove wall is attached to the side of the second side plate 1322 away from the metal frame. On the side of the vertical side wall, that is, the locking portion 140 presses the vertical side wall and the second side plate together in the locking groove 1410. Such as image 3 As shown, the locking portion 140 is also provided with a reinforcing portion 1420 perpendicular to a groove wall of the engaging groove, and the engaging groove and the reinforcing portion 1420 are integrally formed. In the locked state, the reinforcement portion 1420 is attached to the first side plate 1321 to enhance the attachment degree of the locking portion 140 and the linkage rod 1320. Preferably, the end of the groove wall of the engaging groove 1410 that is attached to the vertical side wall is cylindrical, which increases the elasticity of the engaging groove, and clamps the vertical side wall and the second side plate in the locked state, Clamp the vertical side wall in the unlocked state. When the lock is released, the locking part 140 is removed to keep the linkage cover away from the metal frame, and then the locking part is re-locked to the vertical side wall of the metal frame to prevent loss.
 As a preferred embodiment, wheels 150 (such as Image 6 with 7 (Shown) to facilitate the movement of the breeding device and avoid problems such as large moving radius and difficult steering when using a forklift. More preferably, the corners of the two metal frames corresponding to the cover are respectively provided with steering wheels, and the other two corners are respectively provided with directional wheels. Specifically, as an example, for a metal frame mounted with a breeding box with a size of 2 meters * 1 meter * 0.2 meters, the distance between two directional wheels is 1 meter, and the distance between two steering wheels is 1 meter. The distance between the directional wheel and the steering wheel is 1.9 meters to improve the stability of the metal frame.
 The breeding box of the present invention adopts a structure with a side opening, which solves the difficulties in feeding, unloading, overall cleaning and disinfection, and manual insect throwing operations, and the technical problems of long unloading process time and more labor, reducing mechanical vacuum suction And the complexity and labor intensity caused by manual cleaning;
 Further, the present invention adopts the linkage cover, which is fully opened once, and the material is discharged by gravity. The operation is simple, no machinery is required, and the discharge speed is fast; once dead insects and infectious diseases occur, the breeding device can be pushed outdoors, one Open the button for unloading, and ventilate and dry after disinfection, which takes a short time and low labor intensity;
 Furthermore, the sides of the culture box of the present invention are all made of transparent acrylic board, and the bottom is made of PP board, which solves the problems of heavy, difficult to move and high labor intensity in the prior art culture device. At the same time, the acrylic board and PP board have good anti-corrosion performance. , The service life is long, and the cost is greatly reduced compared with the existing technology of glass fiber reinforced plastic culture plate;
 Further, the culture box of the present invention adopts a transparent acrylic board, which improves the visibility of the culture process, facilitates the monitoring of insects, and can easily observe the growth of the insects in each layer of the culture tray and the dry humidity of the material without manually climbing one layer Observe in the gap. At the same time, taking advantage of the phototaxis of insects, the transparent acrylic board can greatly reduce the probability of insects escaping, prolonging the time for insects to forage inside the material, and the acrylic board is smooth, making it more difficult for insects to escape.
