Description

TECHNICAL FIELD

[0001] The present application relates to a silkworm rearing appliance and a breeding device, and relates to the technical field of silkworm breeding. BACKGROUND

[0002] With the industrialization of silkworm breeding, there are many types of devices and appliances used in silkworm rearing, cocooning and other links, and the design of these devices or appliances is basically aimed at improving the efficiency of silkworm breeding.

[0003] The patent application with publication number CN114653656A discloses a factory silkworm breeding frame, which comprises a frame body, and a ventilation groove is arranged on the side of the frame body. The frame body is characterized in that: symmetrically distributed in the frame body are shelf clamping seats, the shelf clamping seat comprises a fixed supporting block and an L-shaped clamping block, the L-shaped clamping block is arranged on the fixed supporting block, the fixed supporting block is arranged on the bottom plate of the frame body, and the inner side of the L-shaped clamping block is provided with an elastic arch strip; the bottom of the fixed supporting block is provided with an extension part, the extension part penetrates through the bottom plate of the frame body, and the bottom plate of the frame body is provided with a ventilation hole.

[0004] The breeding frame has the following shortcomings: only the ventilation groove on the side of the breeding frame can ventilate, so that the air circulation effect of the breeding frame is general. In addition, the side of the breeding frame is provided with a reinforcing rib to improve the structural strength to avoid deformation under pressure after stacking multiple layers, however, the reinforcing rib and the like will weaken the performance of the ventilation groove in circulating air to some extent, so that the air circulation effect becomes worse.

[0005] The patent application with publication number CN114073243A discloses a breeding shelf convenient for stacking, which comprises a plate body. The plate body is provided with a mesh plate. The mesh plate is formed with feeding holes, which facilitates the silkworms to climb from below the shelf to the shelf through the feeding holes, thereby realizing self-transfer of the silkworms. In this process, the silkworm feeding environment is replaced, and the silkworms are conveniently transferred to the next-age feeding frame, solving the problem of silkworm transfer.

[0006] The shelf has the following shortcomings: first, after stacking, a certain gap distance is needed between the two partitions to provide space for the silkworms to move, and too small a gap is not conducive to the free movement of the silkworms and may even cause the silkworms to be crushed. However, too large a gap between the partitions will increase the difficulty of the silkworms climbing up, especially for the low-age stage of the silkworms, which makes them unable to climb up to the upper layer of the shelf, thereby affecting the feeding and growth of the silkworms.

[0007] The patent application with the publication number CN210157875U discloses a cluster device facilitating cocoon discharge, which comprises a frame and a mounting plate, further comprises a cluster cage, the mounting plate is provided with a cluster cage through slot, the cluster cage is fixedly installed on the cluster cage through slot, and the bottom of the cluster cage is provided with an ejection device; the frame, the mounting plate and the cluster cage are main bodies of the device, provide space for silkworm cocooning, and can protect the produced cocoon.

[0008] The cluster device has the following defects: each cluster cage can only allow a single silkworm to cocoon, so that the silkworms have a competition mechanism when climbing into the cluster cage, which greatly affects the cocooning efficiency of the silkworms. In addition, generally, before the silkworms cocoon, a catalyst such as ecdysone is added to their feed to accelerate the cocooning speed. In this case, the silkworms that need to move and climb to the edge of the cluster cage may also have the phenomenon of premature cocooning, which affects the collection of subsequent cocoons. SUMMARY

[0009] The technical problem to be solved by the present application is to provide a silkworm rearing device that facilitates the movement of silkworms and reduces the difficulty of climbing.

[0010] The present application is achieved by the following technical solutions.

[0011] A silkworm rearing device, comprising a rearing plate having at least one hollow area, the hollow area being provided with a cover layer made of flexible material; the cover layer is provided with holes for silkworms to climb; the cover layer is used to place rearing paste, and the part where the rearing paste is placed collapses downward under gravity to form a feeding area.

[0012] As a further improvement of the present application, the cover layer is provided as a mesh, and the mesh holes of the mesh form the holes for silkworms to climb.

[0013] As a further improvement of the present application, the mesh holes of the mesh are hexagonal mesh holes.

[0014] As a further improvement of the present application, the mesh is made of nylon material.

[0020] The present application has the following advantages:

[0021] By arranging the covering layer of flexible material on the breeding plate, a space sufficient for the movement of the silkworms is formed between the two adjacent covering layers, and by using the feature that the covering layer collapses downward under pressure, the part of the covering layer where the feed is placed forms a downward-collapsing feeding area, and the corresponding gap distance is shortened, thereby facilitating the climbing of the silkworms, especially the low-age silkworms.

[0033] The present application will be further described in detail below according to the drawings and embodiments.

[0034] The orientation terms mentioned or possibly mentioned in the present specification, such as up, down, left, right, front, back, front side, back side, top, bottom, etc., are defined with respect to the structure shown in the drawings, and the words "inner" and "outer" refer to the direction towards or away from the geometric center of a particular component, which are relative concepts, so they can change accordingly according to different positions, different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0035] Referring to Figure 1 A silkworm breeding device, comprising a breeding frame 1, a breeding plate 2, and a cocooning tray 3. The breeding frame 1 is a tool for carrying the breeding plate 2 and the cocooning tray 3. The breeding plate 2 is used for feeding silkworms. Multiple breeding plates 2 are used in use, generally 3-5 breeding plates 2 are used, and are stacked in the breeding frame 1. All breeding plates 2 can be stacked in the breeding frame 1, or the used breeding plates 2 can be removed from the breeding frame 1, and only 2 layers of breeding plates 2 are retained in the breeding frame 1. The cocooning tray 3 is used for silkworm cocooning, and is placed at the uppermost position in the breeding frame 1, i.e. above the multiple layers of stacked breeding plates 2.

[0036] One breeding frame 1 is used for breeding one cage of silkworms. In the actual application process of breeding silkworms, multiple breeding frames 1 are stacked to breed multiple cages of silkworms, thereby realizing an efficient industrialized silkworm breeding mode.

[0037] Referring to Figures 2-5 The multiple layers of stacked breeding frames 1 form a silkworm breeding carrier. The breeding frame 1 comprises a bottom plate 11 and four fence plates 12 that jointly form a rectangular enclosure. The width of the fence plate 12 defines the loading space in the breeding frame 1, i.e. the number of layers of breeding plates 2 that can be stacked in the breeding frame 1. The top edge of the fence plate 12 has a load-bearing plate 13 that is bent outward. In a top view, the load-bearing plate 13 has a rectangular edge structure. The bottom surface of the bottom plate 11 is provided with a plurality of support seats 14 at the edges. When multiple layers of breeding frames 1 are stacked to form a breeding carrier, the support seats 14 separate the adjacent two layers of breeding frames 1 and form a ventilation window 1-A for the silkworms in the breeding frame 1 to breathe. The ventilation window 1-A is a fully open and circumferentially transparent window, which can achieve excellent ventilation effect.

[0038] The bottom of the support seat 14 has a support plate 141, which is used to support the load bearing plate 13 of the next layer of the breeding frame 1. Due to the arrangement of the support seat 14, the actual contact part of the adjacent two layers of the breeding frame 1 is less, and therefore the load bearing plate 13 formed by bending 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 support effect. The bottom surface of the support plate 141 has a protruding first positioning clamping corner 142, which is clamped in the inner wall of the fence plate 12 of the next layer of the breeding frame 1, and plays a positioning role between layers to avoid the occurrence of deflection of the breeding carrier.

[0039] In the present embodiment, the bottom plate 11 is provided with the support seat 14 at the four corners of the bottom surface, and depending on the specific size of the breeding frame 1, additional support seats 14 can also be added at other positions of the edge of the bottom plate 11.

[0040] The fence plate 12 is arranged obliquely, and is inclined outward from the bottom edge to the top edge, so that the inner circumference of the fence plate 12 gradually decreases from top to bottom. The surface of the first positioning clamping corner 142 for clamping with the inner wall of the fence plate 12 is arranged obliquely and basically fits on the inner wall of the fence plate 12. During the process of stacking the current layer of the breeding frame 1 on the next layer of the breeding frame 1, the first positioning clamping corner 142 will first fall into the range surrounded by the top of the fence plate 12 of the next layer of the breeding frame 1, and the first positioning clamping corner 142 will not be in contact with the fence plate 12, so as to avoid the current layer of the breeding frame 1 being stuck when it is inclined in the horizontal direction, and also to avoid the friction caused by the first positioning clamping corner 142 and the fence plate 12 always being in contact when stacking. When the current layer of the breeding frame 1 is completely stacked on the next layer of the breeding frame 1, the first positioning clamping corner 142 will fit on the inner wall of the fence plate 12, thereby completely locking the position of the current layer of the breeding frame 1.

[0041] The fence plate 12 is provided with a plurality of air permeable grooves 1-B that penetrate in and out, and the silkworm breeding carrier takes the air permeable window 1-A between the adjacent two layers of the breeding frame 1 as the main air permeable channel, and the air permeable grooves 1-B on the fence plate 12 of each layer of the breeding frame 1 as the auxiliary air permeable channel, forming a relatively perfect and excellent air permeable and ventilation mechanism.

[0042] When the number of layers of the silkworm breeding carrier is high, the load of the breeding frame 1 in the lower layers is heavy, and the fence plate 12 is particularly prone to compression bending due to the spacing of the adjacent layers of the breeding frame 1 by the support seat 14. Therefore, the outer wall of the fence plate 12 is provided with at least one fence transverse reinforcing rib 121 and a plurality of fence vertical reinforcing ribs 122 spaced from each other and intersecting with the fence transverse reinforcing rib 121, the upper and lower ends of the fence vertical reinforcing rib 122 are connected to the support plate 141 and the part of the bottom plate 11 outside the fence plate 12, respectively, so that the structural strength of the fence plate 12 is enhanced, and it has better load performance to avoid bending.

[0043] The middle part of the fence plate 12 is the most easily bent and deformed part, so the structural strength of this part needs to be additionally enhanced. The middle part of the outer wall of the fence plate 12 is provided with a plurality of fence diagonal reinforcing ribs 123 which intersect with the fence transverse reinforcing rib 121 and the fence vertical reinforcing rib 122. Obviously, the arrangement of the fence diagonal reinforcing rib 123 will cause the part of the air vent 1-B in the middle part of the fence plate 12 to be blocked, but since the air vent 1-A is the main air vent, the air vent performance of the air vent 1-B in the middle part of the fence plate 12 is slightly weakened, which does not affect the overall air vent performance.

[0044] In addition, if the number of layers of the silkworm breeding carrier is small and the number of silkworms fed in the breeding frame 1 is small, the silkworm breeding carrier has relatively low air permeability performance, and at this time, the bottom of the breeding frame 1 can not be provided with the support seat 14. The top surface of the support seat 14 is attached to the bottom surface of the bottom plate 11, and the top surface of the support seat 14 extends an installation plate attached to the bottom surface of the bottom plate 11, and the installation plate is provided with a detachable fastener penetrating the installation plate and inserted and fixed on the bottom surface of the bottom plate 11, so that the support seat 14 and the breeding frame 1 are detachably connected, facilitating flexible selection and use.

[0045] The bottom surface of the bottom plate 11 has a second positioning and clamping corner 111 protruding therefrom, and the top surface of the mounting seat has a groove, and the second positioning and clamping corner 111 is inserted into the groove. After the support seat 14 is detached, the second positioning and clamping corner 111 is used to be clamped in the inner wall of the fence plate 12 of the next layer of breeding frame 1, that is, when the breeding frame 1 is used without the support seat 14, the second positioning and clamping corner 111 can still be clamped with the fence plate 12 to position the breeding frame 1.

[0046] Further, the bottom surface of the bottom plate 11 is provided with a plurality of bottom plate reinforcing ribs 112 intersecting with each other, and the two ends of the bottom plate reinforcing rib 112 are connected to the second positioning and clamping corner 111. The second positioning and clamping corner 111 can not only be used for clamping and positioning with the fence plate 12, but also form a structure with the bottom plate reinforcing rib 112 to enhance the strength of the bottom plate 11.

[0047] Referring to Figure 6 , Figure 7 , the cultivation plate 2 constitutes a rearing tool for silkworms, and has at least one hollow area 21 provided with a cover layer 22 made of a flexible material, the cover layer 22 being provided with holes 22R for silkworms to climb, the cover layer 22 being used to place rearing paste, and the part where the rearing paste is placed collapses downward under gravity to form a feeding area 22a. The cultivation plate 2 is stacked in multiple layers in the cultivation frame 1 to rear silkworms, and the bottom plate 11 of the cultivation frame 1 is provided with a plurality of positioning members 11A at the edges and in a vertical manner, and the edges of the cultivation plate 2 are provided with a plurality of notches 2A that avoid the positioning members 11A, and the positioning members 11A and the notches are used to position the cultivation plate 2 in the cultivation frame 1.

[0048] When rearing silkworms, first, place the first cultivation plate 2 on the bottom plate 11 in the cultivation frame 1, place several rows of rearing paste on the cover layer 22 of the first cultivation plate 2, and then place the first instar silkworms on the cover layer 22 of the first cultivation plate 2 to feed, when the silkworms feed and excrete on the first cultivation plate 2, the environment of the first cultivation plate 2 is no longer suitable for continued rearing, and a second cultivation plate 2 needs to be stacked on the first cultivation plate 2, the cultivation plate 2 has a certain thickness, and the cover layer 22 is relatively thin, the gap distance between the two cover layers 22 is basically the same as the thickness of the cultivation plate 2, forming a space for silkworms to move. The distribution of silkworms on the cover layer 22 is relatively uniform, and since the cover layer 22 is made of a flexible material, based on the elasticity and tension of the material, it has the characteristic of collapsing downward under gravity, and due to the uniform distribution of silkworms on the cover layer 22, the degree of downward collapse of the cover layer 22 of the first cultivation plate 2 is moderate and uniform. Then place several rows of rearing paste on the cover layer 22 of the second cultivation plate 2, and the cover layer 22 collapses downward under gravity at the part where the rearing paste is placed to form a feeding area 22a, that is, the feeding area 22a collapses downward to a greater extent, while the remaining part collapses downward to a lesser extent, at this time, the gap distance between the two cover layers 22 corresponding to the feeding area 22a is relatively small, while the gap distance between the two cover layers 22 corresponding to the remaining part is relatively large. Since silkworms have the characteristic of climbing upward, and are induced by the rearing paste, silkworms will tend to climb to the cover layer 22 of the second cultivation plate 2 at the corresponding position of the feeding area 22a to feed.

[0049] The present embodiment can provide a space for silkworms to move by providing a cover layer 22, to avoid crushing silkworms, and the cover layer 22 is made of a flexible material and has the characteristic of collapsing downward under gravity, so that after placing the rearing paste, the gap distance corresponding to the feeding area 22a is reduced, which is conducive to the upward climbing of silkworms.

[0050] In the present embodiment, the cover layer 22 is provided as a mesh, the mesh holes of which form the holes 22R for the silkworms to climb, so that the cover layer 22 has the characteristics of being more lightweight and thinner, and has better structural flexibility, and the holes 22R are less likely to be torn. More specifically, the mesh holes are provided as hexagonal mesh holes, which have a more stable structure and are less likely to be damaged by pulling, and provide a more stable climbing channel for the silkworms. The mesh is made of nylon material, which has high ductility and softness, and is less likely to deform after use, and is more durable.

[0051] Further, the edge portion of the cover layer 22 is fixed to the top surface of the cultivation plate 2, and the remaining portion covers the hollowed-out area 21, that is, the actual area of the cover layer 22 is slightly larger than the hollowed-out area 21. More specifically, the edge of the cover layer 22 is thermally compressed and fixed to the top surface of the cultivation plate 2, so that the top surface of the cultivation plate 2 remains planar after the cover layer 22 is fixed, and does not adversely affect the stacking of multiple layers of cultivation plates 2.

[0052] Any two adjacent cultivation plates 2 have an insertion piece 23 and an insertion slot 24 respectively arranged on the opposite surfaces thereof in a plug-in manner, and the insertion piece 23 and the insertion slot 24 are arranged at the edge of the cultivation plate 2, so as to avoid the misalignment of the two adjacent cultivation plates 2.

[0053] Referring to Figures 8-10 , the bottom edge of the cocooning disc 3 is supported on the top of the positioning piece 11A, and the cocooning disc 3 has cocooning grids 31 uniformly distributed and penetrating through the top and bottom thereof, and the edge of the cocooning grid 31 is provided with a plurality of vertical cocooning columns 32. By utilizing the upward climbing characteristic of the silkworms, the silkworms climb from the last block cultivation plate 2 to the cocooning disc 3, climb to the cocooning disc 3 from the cocooning grid 31, and spin silk on the cocooning column 32, so as to be positioned in the cocooning grid 31 to form cocoons.

[0054] For the last feeding of the silkworms, a component for promoting cocooning of the silkworms, such as ecdysone, is usually added, that is, a feeding paste containing ecdysone is placed on the cover layer 22 of the last cultivation plate, which will make the silkworms cocoon as soon as possible. However, the silkworms are mainly concentrated in the area where the feeding paste is placed on the cover layer 22 and the vicinity thereof, and the coverage of the cocooning disc 3 is much larger than the area where the silkworms are located, so the speed at which the silkworms climb to the cocooning disc 3 and each silkworm occupies a separate cocooning grid 31, that is, the speed at which the silkworms cover the entire cocooning disc 3, will be slower. Since the last feeding paste contains ecdysone, some silkworms that have moved to the edge of the cultivation plate 2 will cocoon on the cultivation plate 2 before they climb upward.

[0055] Based on this, the cocooning grid 31 located or close to the side edge of the cocooning tray 3 has an erected induction column 33 with a water-absorbing material core 34 embedded therein and soaked in mulberry leaf water. The induction column 33 has a plurality of air-permeable holes 33a in communication with the core 34 for emitting the smell to attract silkworms, i.e. the induction column 33 emits the smell to attract silkworms at the edge of the cocooning tray 3, so that after the cocooning tray 3 is placed in the rearing frame 1, the silkworms will quickly spread around from the originally concentrated area, and the distribution of the silkworms on the rearing plate 2 before climbing to the cocooning tray 3 will be close to the coverage of the cocooning tray 3. On the one hand, the induction mechanism caused by the induction column 33 can make the silkworms quickly spread around, avoiding early cocooning before climbing to the cocooning tray 3; on the other hand, since each cocooning grid 31 can only accommodate one silkworm to cocoon, the climbing competition of the silkworms can be reduced, and the congestion phenomenon caused by some silkworms climbing to the occupied cocooning grid 31 and then searching for other empty cocooning grids 31 can be avoided.

[0056] Further, the induction column 33 is arranged at the edge of the cocooning grid 31 located at the edge of the cocooning tray 3, and one induction column 33 is arranged every two to three cocooning grids 31. The arrangement position and number of the induction column 33 only need to meet the requirement of inducing the silkworms to move and spread around, and too many induction columns 33 do not need to be arranged.

[0057] The induction column 33 has an embedded channel 33b therein, the embedded channel 33b forms an opening at the top of the induction column 33, the air-permeable holes 33a are in communication with the embedded channel 33b and form openings at the side of the induction column 33, the core 34 is in a columnar structure and is inserted into the embedded channel 33b. In specific use, the core 34 can be soaked in mulberry leaf water first, and then inserted into the induction column 33 from the embedded channel 33b after being fully soaked. The core 34 and the induction column 33 can be separated and the core 34 is convenient to replace.

[0058] The top end of the induction column 33 is provided with a pressing rod 35 slidingly inserted into the embedded channel 33b, the pressing rod 35 can slide along the embedded channel 33b to press the core 34. By pressing the pressing rod 35 downward, the pressing rod 35 can squeeze out part of the mulberry leaf water of the core 34, so that the smell emitted by the induction column 33 is more pungent. This operation mode can be used when the spreading speed of the silkworms is insufficient.

[0059] In addition, the pressing rod 35 is provided with a stop structure 351 which can abut against the top of the induction column 33 to limit the sliding distance of the pressing rod 35 downward, so as to avoid that the pressing force of the pressing rod 35 downward is too heavy and causes damage to the core 34.

[0060] Further, the induction column 33 comprises a base column 331 arranged at the edge of the cocooning grid 31, and a connecting column 332 detachably connected to the top end of the base column 331, and the core 34 is arranged on the connecting column 332. It is inconvenient to directly insert the core 34 on the cocooning disc 3, and the induction column 33 is arranged in a detachable structure, the core 34 is inserted into the connecting column 332, and the connecting column 332 and the base column 331 are connected during 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 insertion block 3B that is matched with the slot 3A, and the detachable mode of the clamping connection is relatively convenient to operate.

[0061] For the cocooning disc 3, the cocooning disc 3 comprises a rectangularly enclosed frame 3-1, and a rib 3-2 arranged in the frame and in a cross arrangement, the rib 3-2 forms the edge of the cocooning grid 31, which can make the cocooning disc 3 more lightweight and reduce the load of the breeding frame 1 under the premise of ensuring the structural strength of the cocooning disc 3.
