These and other directional terms should not be construed as limiting terms.

Referring to fig. 1, a silkworm rearing device includes: 1 cultivation frame, 2 cultivation plate, 3 cocooning tray. The cultivation frame 1 is an appliance carried by the cultivation plate 2 and the cocoon forming tray 3, the cultivation plate 2 is used for feeding silkworms, a plurality of cultivation plates are used during use, generally 3-5 cultivation plates are used, the cultivation plates are stacked in the cultivation frame 1, all cultivation plates can be stacked in the cultivation frame 1, and used cultivation plates 2 can be pulled out from the cultivation frame 1, and only 2 layers are reserved in the cultivation frame 1. The cocoon-forming tray 3 is used for cocooning of silkworms, and is placed at the uppermost part in the cultivation frame 1, that is, above the cultivation plates 2 stacked in multiple layers.

One cultivation frame 1 is used for carrying out one-cage silkworm cultivation, and in the application process of actually cultivating silkworms, a plurality of cultivation frames 1 are generally stacked for carrying out multi-cage silkworm cultivation, so that an efficient industrialized silkworm cultivation mode is realized.

Referring to fig. 2 to 5, the cultivation frame 1 stacked in multiple layers constitutes a cultivation carrier for silkworms, the cultivation frame 1 comprises a bottom plate 11, four fence plates 12 which together form a rectangular enclosure, and the width of the fence plates 12 defines a loading space in the cultivation frame 1, namely, the number of layers of cultivation plates 2 which can be stacked in the cultivation frame 1. The top edge of the fence plate 12 is provided with a bearing plate 13 formed by bending outwards, and the bearing plate 13 is in a rectangular edge strip structure in a top view. The bottom surface of the bottom plate 11 is provided with a plurality of supporting seats 14 at the edge, and under the condition that the multi-layer cultivation frames 1 are stacked to form a cultivation carrier, the supporting seats 14 space the two adjacent layers of cultivation frames 1, and a ventilation window 1-A for ventilation of silkworms in the cultivation frames 1 is formed, and the ventilation window 1-A is a fully-opened and circumferentially-transparent window, so that an excellent ventilation effect can be obtained.

The bottom of the supporting seat 14 is provided with a supporting plate 141, and the supporting plate 141 is used for supporting on the bearing plate 13 of the next layer of cultivation frame 1. Because of the arrangement of the support base 14, the actual contact parts of the two adjacent layers of cultivation frames 1 are fewer, and therefore the bearing plate 13 formed by bending at the top end of the fence plate 12 actually increases the width of the top end of the fence plate 12, thereby increasing the contact area to obtain a more stable supporting effect. The bottom surface of the supporting plate 141 is provided with a first positioning clamping angle 142 formed by protruding, and the first positioning clamping angle 142 is clamped and embedded on the inner wall of the fence plate 12 of the next layer of cultivation frame 1, so that the positioning effect between layers is achieved, and the situation that the cultivation carrier is inclined is avoided.

In this embodiment, the base plate 11 is provided with the supporting seats 14 at four corners of the bottom surface, and the supporting seats 14 may be additionally provided at other positions of the edge of the base plate 11 based on the specific specification and size of the cultivation frame 1.

The fence panel 12 is inclined and inclined outwardly from its bottom edge to its top edge such that the inner periphery of the fence panel 12 tapers from top to bottom. The first locating clip angle 142 is configured to be disposed obliquely to a surface of the fence panel 12 that engages the inner wall of the fence panel 12 and substantially conforms to the inner wall of the fence panel 12. In the process of stacking the cultivation frame 1 of the current layer on the cultivation frame 1 of the next layer, the first positioning clamping angle 142 falls into a range surrounded by the tops of the fence plates 12 of the cultivation frame 1 of the next layer, and the first positioning clamping angle 142 is not contacted with the fence plates 12, so that the situation that the cultivation frame 1 of the current layer is clamped when being inclined in the horizontal direction is avoided, and the friction force generated by the fact that the first positioning clamping angle 142 and the fence plates 12 are always contacted when being stacked is avoided. When the current layer of cultivation frame 1 is completely overlapped on the next layer of cultivation frame 1, the first positioning clamping angle 142 is attached to the inner wall of the fence plate 12, so that the position of the current layer of cultivation frame 1 is completely locked.

A plurality of ventilation grooves 1-B which are communicated with the inside and the outside are arranged on the fence plate 12, the silkworm breeding carrier takes a ventilation window 1-A between two adjacent layers of breeding frames 1 as a main ventilation channel, and the ventilation grooves 1-B on the fence plate 12 of each layer of breeding frame 1 are taken as auxiliary ventilation channels, so that a ventilation mechanism with perfect effect is formed.

When the number of layers of the silkworm breeding carriage is high, the breeding frames 1 positioned at the middle and lower layers are heavy in load, and the fence plates 12 are particularly easy to be subjected to compressive bending due to the fact that the supporting seats 14 are spaced apart from the breeding frames 1 positioned at the adjacent layers. Therefore, the outer wall of the fence plate 12 is provided with at least one fence transverse reinforcing rib 121, a plurality of fence vertical reinforcing ribs 122 which are mutually spaced and mutually crossed with the fence transverse reinforcing ribs 121, and the upper and lower ends of the fence vertical reinforcing ribs 122 are respectively connected with the supporting plates 141 and the parts of the bottom plate 11 positioned outside the fence plate 12, so that the structural strength of the fence plate 12 is enhanced, and the fence plate 12 has better load performance so as not to be bent.

The mid-portion of the fence panel 12 is the most pliable and deformable portion and therefore requires additional reinforcement in terms of structural strength. A plurality of fence oblique reinforcing ribs 123 are arranged in the middle of the outer wall of the fence plate 12, and the fence oblique reinforcing ribs 123, the fence transverse reinforcing ribs 121 and the fence vertical reinforcing ribs 122 are mutually intersected. It is apparent that the provision of the diagonal rail stiffener 123 results in the central ventilation slot 1-B of the fence panel 12 being partially blocked, but since the ventilation window 1-a is the primary ventilation channel, the ventilation of the central ventilation slot 1-B of the fence panel 12 is slightly impaired and is not sufficient to affect the overall ventilation.

In addition, if the number of layers of the silkworm breeding carrier is small and the number of silkworms bred in the breeding frame 1 is small, the silkworm breeding carrier has relatively low ventilation performance, and the bottom of the breeding frame 1 may not be provided with the supporting seat 14. The top surface laminating of supporting seat 14 is in the bottom surface of bottom plate 11 to the top surface of supporting seat 14 extends there is the mounting panel of laminating on the bottom surface of bottom plate 11, be equipped with on the mounting panel and run through the mounting panel and insert and establish the detachable fastener of fixing on the bottom surface of bottom plate 11, make supporting seat 14 and breed frame 1 can dismantle the connection, be convenient for select in a flexible way and use.

The bottom surface of the bottom plate 11 is provided with a second positioning clamping angle 111 formed by protruding, the top surface of the mounting seat is provided with a groove, the second positioning clamping angle 111 is inserted into the groove, after the supporting seat 14 is detached, the second positioning clamping angle 111 is used for being clamped on the inner wall of the fence plate 12 of the next layer of cultivation frame 1, namely, when the cultivation frame 1 is used without using the supporting seat 14, the second positioning clamping angle 111 can still be clamped with the fence plate 12 to position the cultivation frame 1.

Further, a plurality of mutually-intersected bottom plate reinforcing ribs 112 are arranged on the bottom surface of the bottom plate 11, two ends of the bottom plate reinforcing ribs 112 are connected with second positioning clamping angles 111, and the second positioning clamping angles 111 not only can be used for clamping and positioning the fence plate 12, but also can form a structure with the bottom plate reinforcing ribs 112 to strengthen the bottom plate 11.

Referring to fig. 6 and 7, the cultivation plate 2 forms a silkworm rearing tool, the cultivation plate 2 has at least one hollowed-out area 21, the hollowed-out area 21 is provided with a cover layer 22 made of flexible materials, holes 22R are paved on the cover layer 22 for the silkworms to climb, the cover layer 22 is used for placing rearing paste, and a part where the rearing paste is placed is collapsed downwards by weight to form a feeding area 22a. The cultivation board 2 is stacked in multiple layers and placed in the cultivation frame 1 to feed silkworms, a plurality of locating pieces 11A which are arranged at the edges of the bottom plate 11 of the cultivation frame 1 and are in a vertical shape are arranged on the edges of the cultivation board 2, a plurality of notches 2A avoiding the locating pieces 11A are formed in the edges of the cultivation board 2, and the locating pieces 11A and the notches are used for locating the positions of the cultivation board 2 in the cultivation frame 1.

When raising silkworms, firstly, the first culture plate 2 is placed on the bottom plate 11 in the culture frame 1, a plurality of raising pastes are placed on the cover layer 22 of the first culture plate 2, then the silkworms of 1 age are put on the cover layer 22 of the first culture plate 2, when the silkworms eat and excrete on the first culture plate 2, the environment of the first culture plate 2 is not suitable for continuous raising, the second culture plate 2 is required to be stacked on the first culture plate 2, the culture plate 2 has a certain thickness, the cover layer 22 is a thinner layer, the gap distance between the two cover layers 22 is basically the same as the thickness of the culture plate 2, and a space for the silkworms to move is formed. The silkworms are distributed relatively uniformly on the covering layer 22, and the covering layer 22 is made of flexible materials, so that the silkworms have the characteristic of downward collapse of audiences based on the elasticity and the tensioning degree of the materials, and meanwhile, the covering layer 22 of the first culture plate 2 is moderate and uniform in downward collapse degree due to the uniform distribution of the silkworms on the covering layer 22. Then, a plurality of feeding pastes are placed on the cover layer 22 of the second culturing plate 2, and the cover layer 22 is collapsed downward by gravity at the portion where the feeding paste is placed to form a feeding region 22a, that is, the feeding region 22a is collapsed downward to a greater extent and the rest is collapsed downward to a lesser extent, at which time the gap distance between the two cover layers 22 corresponding to the feeding region 22a is relatively small and the gap distance between the two cover layers 22 corresponding to the rest is relatively large. Since the silkworms have a characteristic of climbing upward, and under the induction of the feeding paste, the silkworms tend to climb up to the cover layer 22 of the second culturing plate 2 at the position corresponding to the feeding area 22a to eat.

According to the embodiment, through the arrangement of the cover layer 22, firstly, a space for silkworm to move can be provided so as to avoid crush injury to the silkworms, and secondly, the cover layer 22 is made of flexible materials and has the characteristic of heavy downward collapse, so that the gap distance corresponding to the feeding area 22a is reduced after the feeding paste is placed, and the silkworms climb upwards.

In this embodiment, the cover layer 22 is formed as a woven net, and the holes 22R for the silkworm to climb are formed by the mesh openings of the woven net, so that the cover layer 22 has the characteristics of lighter weight and thinner thickness, and meanwhile, the structure toughness is better, and the holes 22R are not easy to tear. More specifically, the mesh of the netting is set to be a hexagonal mesh, the structure of the hexagonal mesh is more stable, the netting is not easy to pull and damage, and a more stable climbing channel for silkworms is provided. The net is made of nylon materials, the ductility and the softness of the nylon materials are high, the net is not easy to deform after being used, and the net is durable.

Further, the edge portion of the cover layer 22 is fixed on the top surface of the culture plate 2, and the rest portion covers the hollowed-out area 21, that is, the actual area of the cover layer 22 is slightly larger than that of the hollowed-out area 21, more specifically, the edge of the cover layer 22 is pressed on the top surface of the culture plate 2 by thermoplastic pressing, that is, the top surface of the culture plate 2 is still in a planar structure after the cover layer 22 is fixed, so that the multilayer stacking of the culture plate 2 is not adversely affected.

The opposite surfaces of any two adjacent layers of culture plates 2 are respectively provided with an insert 23 and a slot 24 which are in insert fit, the insert 23 and the slot 24 are arranged at the edge positions of the culture plates 2, and the adjacent two layers of culture plates 2 are prevented from being offset and misplaced through the insert fit of the insert 23 and the slot 24.

Referring to fig. 8-10, the bottom edge of the cocoon forming tray 3 is supported on the top of the positioning member 11A, the cocoon forming tray 3 is provided with uniformly distributed and vertically penetrated cocoon forming cells 31, and the edge of the cocoon forming cells 31 is provided with a plurality of upright cocoon forming columns 32. By utilizing the characteristic that the silkworms climb upwards, the silkworms climb from the last culture plate 2 to the cocoon forming tray 3 and climb from the cocoon forming grid 31 to the cocoon forming tray 3, and silk spinning is carried out on the cocoon forming columns 32, so that the silkworms are positioned in the cocoon forming grid 31 to form cocoons.

For the last feeding of silkworms, ingredients that promote silkworm cocoon formation, such as ecdysone and the like, are usually added, i.e., a raising paste containing ecdysone is placed on the cover layer 22 of the last-placed plate, which causes silkworms to cocoon as soon as possible. However, the silkworms are mainly concentrated in and near the area where the feeder paste is placed in the cover layer 22, and the coverage area of the cocooning tray 3 is much larger than the area where the silkworms are located, so that the silkworms climb up to the cocooning tray 3 and each silkworm occupies an individual cocooning grid 31, i.e., the speed at which the silkworms cover the whole cocooning tray 3 is slow, and the silkworms which have moved partially to the edge position of the culture plate 2 are caused to advance cocooning on the culture plate 2 because of the ecdysone contained in the feeder paste of the last time.

Based on the above, the cocoon forming grid 31 located at or near the side of the cocoon forming tray 3 is provided with a vertical guide post 33 at the edge thereof, the guide post 33 is embedded with a core 34 made of water absorbing material and soaked by mulberry leaf water, the guide post 33 is provided with a plurality of ventilation holes 33a communicated with the core 34 for emitting smell for attracting silkworms, namely, the guide post 33 can make the edge of the cocoon forming tray 3 emit smell for attracting silkworms, so that after the cocoon forming tray 3 is placed in the cultivation frame 1, the silkworm is attracted to be rapidly spread from the originally concentrated area to the periphery, and the distribution of silkworms on the cultivation plate 2 is close to the coverage of the cocoon forming tray 3 before climbing to the cocoon forming tray 3. On the one hand, the induction mechanism induced by the induction column 33 can enable the silkworms to rapidly spread around, so that cocoons are prevented from being formed in advance before climbing to the cocooning tray 3; on the other hand, each cocoon forming grid 31 can only hold one silkworm for forming cocoons, so climbing competition of the silkworms can be reduced, and congestion caused by the fact that some silkworms climb to occupied cocoon forming grids 31 and then find other empty cocoon forming grids 31 is avoided.

Further, the guiding columns 33 are arranged on the edges of the cocoons forming grids 31 positioned at the edges of the cocoons forming tray 3, one guiding column 33 is arranged on every two to three cocoons forming grids 31 at intervals, and the positions and the number of the guiding columns 33 are only required to be enough to induce the silkworms to move and spread all around, so that the number of the guiding columns 33 is not required to be too large.

The induction column 33 is provided with an embedded channel 33b, the embedded channel 33b forms an opening at the top of the induction column 33, the ventilation holes 33a are communicated with the embedded channel 33b, an opening is formed at the side surface of the induction column 33, and the core 34 is of a columnar structure and is inserted into the embedded channel 33 b. When the mulberry leaf core is specifically used, the core 34 can be soaked in mulberry leaf water, after the mulberry leaf core is fully soaked, the core 34 is plugged into the induction column 33 through the embedded channel 33b, and the core 34 and the induction column 33 are separable, so that the core 34 can be conveniently replaced.

The top of the induction post 33 is provided with a squeezing rod 35 which is inserted into the embedded channel 33b in a sliding manner, the squeezing rod 35 can slide along the embedded channel 33b and is used for squeezing the core 34, and the squeezing rod 35 can squeeze out part of mulberry leaf water from the core 34 by pressing the squeezing rod 35 downwards, so that the smell emitted by the induction post 33 is more intense, and the operation mode can be adopted when the mulberry diffusion speed is insufficient.

In addition, the pressing rod 35 is provided with a stopping structure 351, and the stopping structure 351 can be abutted against the top of the inducing column 33 to limit the downward sliding distance of the pressing rod 35, so as to prevent the core 34 from being damaged due to excessive force of pressing the pressing rod 35 downward.

Further, the inducing column 33 includes a base column 331 with a bottom end disposed on an edge of the cocoon frame 31, a connecting column 332 detachably connected to a top end of the base column 331, and the core 34 is disposed on the connecting column 332. It is inconvenient to directly insert the core 34 into the cocoon forming tray 3, the inducing column 33 is configured to be detachable, the core 34 is inserted into the connecting column 332, and the connecting column 332 and the base column 331 are connected when in use. More specifically, the top end of the base column 331 has a slot 3A, and the bottom end of the connecting column 332 has an insert 3B engaged with the slot 3A in a clamping manner, so that the operation in a clamping detachable manner is relatively convenient.

For the cocoon forming tray 3, the cocoon forming tray 3 comprises a frame 3-1 which is rectangular and surrounds, ribs 3-2 which are laid in the frame and are arranged in a crossed manner, the ribs 3-2 form the edges of cocoon forming grids 31, and on the premise of ensuring the structural strength of the cocoon forming tray 3, the cocoon forming tray 3 can be lighter, and the bearing of the cultivation frame 1 is lightened.
