DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The present embodiment provides a breeding device for breeding larvae, which is mainly used for rapid screening of larvae during blade replacement.

[0029] like Figure 1 and Figure 4As shown, it includes a feeding box 1 for feeding larvae, wherein a horizontally arranged supporting plate 2 is fixedly installed in the inner cavity of the feeding box 1, wherein the supporting plate 2 is used to place leaves for the larvae to gnaw, and also includes a supporting net 7 located on the supporting plate 2 and pressed above the leaves of the supporting plate 2, wherein the supporting net 7 is used for storing larvae, and a plurality of mesh holes 71 are provided on the supporting net 7. It is worth noting that the aperture of the mesh hole 71 is smaller than the diameter of the larvae, and the arrangement of the mesh hole 71 is only for the larvae to gnaw the leaves, and also includes a lifting rod 36 for lifting the supporting net 7 upward and a locking assembly 6 for fixing the lifting rod 36 on the feeding box 1.

[0030] Through the above arrangement, during the feeding process, the larvae place the leaves above the supporting plate 2 and the larvae on the supporting net 7, and release the restriction of the locking assembly 6 on the supporting net 7. At this time, the supporting net 7 is pressed above the leaves, and the larvae can gnaw the leaves through the mesh holes 71 of the supporting net 7, wherein the excrement of the larvae can fall onto the supporting plate 2 through the mesh holes 71; when it is necessary to clean the gnawed leaves and feces, the supporting net 7 is lifted upward and fixed by the locking assembly 6. Since the mesh holes 71 are smaller than the larvae, the larvae and the leaves can be quickly separated.

[0031] It is worth noting that the edges and corners of the blades can also extend upward through the meshes 71 of the supporting net 7 to be gnawed by the larvae.

[0032] In order to realize the installation of the supporting net 7, in this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the side wall of the feeding box 1 is provided with a first slide groove 11 and a second slide groove 13 arranged longitudinally, wherein the first slide groove 11 and the second slide groove 13 are each provided with a slidably connected supporting block 31, wherein a part of the supporting block 31 extends into the inner cavity of the feeding box 1, and the supporting net 7 is fixed to the top wall of the supporting block 31 by a positioning screw 33, and the lifting rod 36 is fixedly installed on the supporting block 31 and extends vertically upward, and the lifting rod 36 can be used to realize the stable upward movement of the supporting net 7, thereby realizing the separation of the larvae from the leaves.

[0033] In order to prevent the larvae from crawling out of the breeding box 1 from the positions of the first chute 11 and the second chute 13, therefore, in this embodiment, Figure 1 , Figure 3 and Figure 5As shown, a first blocking plate 32 and a third blocking plate 35 are fixedly provided on the two supporting blocks 31, respectively, wherein the first blocking plate 32 extends vertically upward, and the side wall of the first blocking plate 32 is slidably connected to the side wall of the first slide groove 11, and the third blocking plate 35 extends vertically upward, and the side wall of the third blocking plate 35 is slidably connected to the side wall of the second slide groove 13, and the first blocking plate 32 and the third blocking plate 35 are respectively blocked for blocking the first slide groove 11 and the second slide groove 13 to prevent the larvae from crawling out of the inner cavity of the feeding box 1 from the first slide groove 11 or the second slide groove 13.

[0034] In order to enable the supporting net 7 to abut against the carrying plate 2, in this embodiment, as shown in FIG. Figure 4 , Figure 5 and Figure 7 As shown, the support plate 2 is provided with an avoidance hole 22 for the support block 31 to pass through. When the support net 7 moves downward, the support block 31 is inserted into the avoidance hole 22, so that the support net 7 can abut against the top wall of the support plate 2.

[0035] As the larvae eat the leaves, the leaves gradually decrease. In order to ensure that the supporting net 7 is always in contact with the leaves on the supporting plate 2, in this embodiment, Figure 4 , Figure 5 and Figure 6 As shown, a positioning plate 4 is fixedly provided on the outer wall of the feeding box 1, wherein the positioning plate 4 is provided with a through hole 41 for the lifting rod 36 to pass through, and a compression spring 5 is sleeved on the outer side of the lifting rod 36, wherein one end of the compression spring 5 abuts against the top wall of the supporting block 31, and the other end of the compression spring 5 abuts against the bottom wall of the positioning plate 4.

[0036] Through the above arrangement, as the number of blades gradually decreases, the compression spring 5 pushes the support block 31 downward, so that the bottom wall of the support net 7 is pressed against the blades, so that the larvae can gnaw the blades through the mesh 71.

[0037] It is worth noting that the supporting net 7 is connected to the supporting block 31 via positioning screws 33, so as to facilitate replacement of the supporting net 7 with meshes 71 of different diameters to suit larvae at different stages.

[0038] When the blades need to be replaced, the support net 7 needs to move upward and compress the compression spring 5. In order to prevent the support net 7 from falling downward during this process, in this embodiment, Figure 4 , Figure 5 and Figure 6As shown, the locking assembly 6 includes a limit baffle 361, a locking plate 61 and a locking slot 611 arranged on the locking plate 61, wherein the limit baffle 361 is fixedly installed on the peripheral wall of the lifting rod 36, and the locking plate 61 is slidably installed on the positioning plate 4. When the supporting net 7 needs to be locked, the supporting net 7 is lifted upward, and then the locking plate 61 is slid toward the side close to the lifting rod 36, so that the locking slot 611 on the locking plate 61 is inserted into the outer side of the lifting rod 36, and then the bottom wall of the limit baffle 361 is abutted against the top wall of the locking plate 61, thereby limiting the lifting rod 36 from moving downward, thereby completing the locking of the supporting net 7.

[0039] In order to solve the problem of interference of the locking plate 61 with the compression spring 5 during the locking process of the supporting net 7, in this embodiment, as shown in FIG. Figure 5 As shown, one end of the compression spring 5 abuts against the bottom wall of the positioning plate 4 , and the other end of the compression spring 5 abuts against the top wall of the limiting baffle 361 .

[0040] In order to realize the installation of the locking plate 61, in this embodiment, as shown in FIG. Figure 5 and Figure 6 As shown, the positioning plate 4 is provided with a waist-shaped hole 42 which passes through from top to bottom, and the locking assembly 6 also includes a slide rod 62 , wherein the bottom end of the slide rod 62 is fixedly connected to the locking plate 61 , and the peripheral wall of the slide rod 62 is slidably connected to the inner wall of the waist-shaped hole 42 .

[0041] When the supporting net 7 moves upward to Figure 5 In order to facilitate the replacement of the blade residue on the carrier plate 2, in this embodiment, Figure 5 and Figure 6 As shown, the side wall of the feeding box 1 is provided with a notch 12 connected to the inner cavity of the feeding box 1, wherein the notch 12 is divided into two parts, the upper part is a discharge port 122, and the lower part is a discharge port 121. Figure 5 In the state of being in, the discharge port 122 is opened, and the blades on the carrier plate 2 can be pulled outward through the discharge port 122, and then new blades can be placed on the carrier plate 2.

[0042] When the locking assembly 6 releases the locking of the supporting net 7, the supporting net 7 abuts against the carrying plate 2. In order to prevent the larvae from crawling out of the discharge port 122, in this embodiment, Figure 3 and Figure 6 As shown, the top wall of the discharge port 122 is provided with a receiving chamber 14 extending upward, wherein the receiving chamber 14 is communicated with the second chute 13, and a second blocking plate 34 fixedly connected to the third blocking plate 35 and the supporting block 31 is provided inside the receiving chamber 14. When the supporting net 7 is unlocked, as shown in FIG. Figure 4 As shown, the second blocking plate 34 closes the discharge port 122 to prevent the larvae from crawling out of the breeding box 1.

[0043] In order to separate the larvae's feces from the leaf residues, in this embodiment, Figure 4 and Figure 5 As shown, a plurality of discharge holes 21 are provided on the carrier plate 2. When the blade residue is pulled out from the discharge port 122, the blade is shaken on the carrier plate 2, and the larval feces can fall downward from the discharge hole 21, thereby separating the larval feces from the blade residue.

[0044] In order to discharge feces out of the breeding box, in this embodiment, as Figure 5 As shown, a guide plate 15 is provided in the inner cavity of the feeding box 1, wherein the guide plate 15 is located below the supporting plate 2. In order to discharge feces from the discharge port 121, the guide plate 15 is arranged at an angle, and the lowest position of the guide plate 15 is on one side of the discharge port 121. Feces falling onto the guide plate 15 rolls down and is discharged from the inner cavity of the feeding box 1 from the discharge port 121.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
