DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1-3As shown, this embodiment provides a lifting type multi-layer silkworm breeding equipment, including a support frame 1, a lifting drive mechanism arranged on the support frame 1, a plurality of lifting chains 10 arranged at the output end of the lifting drive mechanism, and a plurality of silkworm breeding frames 3 which are detachably connected to the plurality of lifting chains 10 in sequence and spaced up and down. Among them, the support frame 1 is mainly a rectangular frame composed of a plurality of circular tubes. A supporting foot 2 can be arranged at the bottom. The plurality of circular tubes can be connected by a first movable buckle 7 for easy disassembly and transportation. Of course, the support frame 1 can also be made of square tubes, and the connection method between the tubes can also be welding. As a more specific embodiment, the inner length of the entire rectangular frame is 3015 mm, the inner height is 3000 mm, and the inner width is 1500 mm. Of course, it can be designed to other sizes according to actual needs. Figure 1 What is shown is the long side of the support frame 1, and the "front, back, left, and right" described below are all based on this perspective.

[0019] The lifting drive mechanism is generally arranged at the top of the support frame 1, and mainly includes a crossbar shaft 25, a drive device 8, a suspension rope 4 and a transition guide wheel 17. The crossbar shaft 25 is arranged in the middle of the top of the support frame 1 along the length direction of the support frame 1, one end of which is connected to the bearing seat 9, and the other end is connected to the drive device 8. The drive device 8 can generally use a motor or a manual winch. The suspension rope 4 is connected to the crossbar shaft 25 through a fixture 11. There are two fixtures 11. Since a certain winding space is required when the suspension rope 4 is wound on the crossbar shaft 25, the two fixtures 11 are respectively arranged at a certain distance from the bearing seat 9 and the drive device 8, for example, 200 mm. A suspension rope 4 is connected to the left and right sides of each fixture 11. When the drive device 8 is activated, a total of four suspension ropes 4 are synchronously wound or released to achieve synchronous lifting of the lower ends of the four suspension ropes 4. The lifting rope 4 is extended to the front and rear sides of the supporting frame 1, that is, the two sides in the width direction, through the transition guide wheel 17 set on the long side of the top of the supporting frame 1. In this way, the front and rear sides of the supporting frame 1 are respectively provided with two lifting ropes 4. Although the lifting chain 10 can be directly connected to the lower end of the lifting rope 4, since the lifting rope 4 is not at the extreme side, the lifting chain 10 will also be at the front and back of the supporting frame 1, which is not convenient for taking out the silkworm frame 3; therefore, a horizontal balance bar 6 is connected to the lower end of the two lifting ropes 4 on the front side, and a balance bar 6 is connected to the lower end of the two lifting ropes 4 on the rear side, and a lifting chain 10 is connected to each of the two ends of the balance bar 6, so that the position of the lifting chain 10 is closer to the left and right sides of the supporting frame 1, and it is not easy to block the front and back of the supporting frame 1. On the one hand, it is convenient to take out the silkworm frame 3 from the front, and on the other hand, it also provides a wider space for feeding mulberry leaves and other operations, thereby improving convenience.

[0020] A plurality of second articulated buckles 20 can be sequentially arranged on each lifting chain 10 along the length direction thereof, and the spacing distance is set according to actual needs, for example, 600 mm. The distance between the second articulated buckle at the highest position and the balance bar 6 can also be a corresponding 600 mm. In this way, each silkworm rack 3 can be connected to the second articulated buckles 20 at the same height position on the four lifting chains 10 to achieve installation. Accordingly, a connecting hole 14 matching the second articulated buckle 20 needs to be arranged on the silkworm rack 3. The structure of four silkworm racks 3 is shown in the accompanying drawings, and other numbers of silkworm racks 3 can be used as needed. In this way, since the lifting chain 10 is flexible, the four silkworm racks 3 will be stacked together from bottom to top in the process of descent, such as Figure 1 As shown; when rising, it will rise from top to bottom, and the final state is as follows Figure 2 As shown; in order to maintain a certain gap when the silkworm raising frame 3 is stacked, and also to provide a stable support point for the stacking of the silkworm raising frame 3, the four corners of the silkworm raising frame 3 are provided with support members 12 that are higher than the silkworm raising frame 3 and are used to support the bottom of the upper silkworm raising frame 3.

[0021] The silkworm raising frame 3 is mainly a rectangular structure composed of four angle steels, namely, a support plate including side plates and a bottom, so as to integrate or place silkworm plaques in an integrated manner inside, and the above-mentioned support member 12 is arranged on the support plate; a plurality of holes are arranged on the side plates and the support plate, on the one hand to reduce the weight, and on the other hand to facilitate connection with other structures, such as connection with the second movable buckle 20 on the lifting chain 10. Since the lifting chain 10 and the lifting rope 4 are both flexible structures, in order to ensure the stability of the silkworm raising frame 3 during the lifting process, and the position accuracy when multiple silkworm raising frames 3 are stacked, the silkworm raising frame 3 can be designed to have a length equivalent to the inner length of the support frame 1, and a width slightly larger than the inner width of the support frame 1, so that the left and right sides of the silkworm raising frame 3 are limited to the inner side of the support frame 1, that is, the left and right positions of the silkworm raising frame 3 are stabilized, and the silkworm raising frame 3 can be taken out from the front or back. In order to further improve the position stability of the silkworm raising frame 3 during the lifting process, openable and closable anti-sway devices 16 are respectively provided on the left and right side surfaces of the silkworm raising frame 3 to cooperate with the columns of the supporting frame 1 to realize the anti-sway function. Since the left and right positions of the silkworm raising frame 3 are already sufficiently stable, the openable and closable anti-sway device 16 is designed mainly to solve the stability of the front and rear positions of the silkworm raising frame 3. Therefore, in order to reduce the amount of operation and facilitate the removal operation of the silkworm raising frame 3, this embodiment only provides one openable and closable anti-sway device 16 on the left and right side surfaces of the silkworm raising frame 3, and the two openable and closable anti-sway devices 16 are respectively matched with the two columns on the front side of the supporting frame 1. Because once the front end of the silkworm raising frame 3 does not sway back and forth, the whole frame will not sway back and forth either. Therefore, the use of two openable and closable anti-sway devices 16 can achieve a better front and rear anti-sway effect. Of course, the two openable and closable anti-sway devices 16 can also be matched with the two columns on the rear side of the supporting frame 1.

[0022] Specifically, Figure 4 and 5 As shown, the closable anti-sway device 16 includes a mounting plate 161, a first opening and closing plate 162 horizontally rotatably connected to one end of the mounting plate 161, a fixing rod 163 provided at the other end of the mounting plate 161, and a second opening and closing plate 164 rotatably connected to the fixing rod 163, and a matching lock 165 is provided at the upper part of the first opening and closing plate 162 and the lower part of the second opening and closing plate 164. Among them, the rotatable connection structure of the mounting plate 161 and the first opening and closing plate 162 can be realized by using an extended hinge, that is, the two leaf plates of the hinge are used as the mounting plate 161 and the first opening and closing plate 162 respectively, and the mounting plate 161 can be connected to the side of the silkworm raising frame 3 by bolt connection or the like. The fixing rod 163 can be bolted. When installing, first put the second opening and closing plate 164 onto the fixing rod 163, then screw a nut onto the fixing rod 163, and pass through the mounting plate 161 and the side of the silkworm raising frame 3, and then screw another nut, that is, use two nuts to lock the mounting plate 161 and the silkworm raising frame 3, and also realize the installation of the fixing rod 163 itself. When using, first rotate the first opening and closing plate 162 to be close to the side of the column, and then rotate the second opening and closing plate 164 from top to bottom to buckle on the first opening and closing plate 162, and the locks 165 of the two opening and closing plates are buckled with each other to realize the closing of the entire openable and closable anti-sway device 16. At this time, the openable and closable anti-sway device 16 embraces the column to realize the anti-sway function, wherein the fixing rod 163 and the first opening and closing plate 162 are respectively matched with the front and rear sides of the column, playing the front and rear anti-sway function. Before the silkworm rack 3 needs to be moved out, the second opening and closing plate 164 is first rotated upward to disengage from the buckling relationship with the first opening and closing plate 162, and then the first opening and closing plate 162 can be rotated to be close to the side of the silkworm rack 3, so that the openable and closable anti-sway device 16 is in an open state. Since the fixing rod 163 is fixedly arranged, in order to avoid the fixing rod 163 and the column from interfering during the removal of the silkworm rack 3, the fixing rod 163 needs to be arranged on the outside of the support frame 1, and the silkworm rack 3 is moved out from this side. For example, in this embodiment, the openable and closable anti-sway device 16 cooperates with the column on the front side, so the fixing rod 163 needs to be arranged on the front side of the column, and the silkworm rack 3 is moved out from the front side, so the fixing rod 163 will not interfere with the column.

[0023] As mentioned in the background technology, the existing lifting silkworm raising equipment has a large size and weight of silkworm racks, which are generally difficult to take out directly. The upper silkworm racks are easy to press the silkworms in the lower silkworm racks during the removal process. Therefore, the silkworm racks can only be lifted to a suitable position, and the silkworm litter inside the equipment can be cleaned directly from the outside of the equipment, which is inconvenient and inefficient. If the size and weight of the silkworm racks are reduced, the number of silkworms raised will be reduced, affecting the efficiency of silkworm raising. Therefore, it is difficult for the existing lifting silkworm raising equipment to take into account both the convenience of silkworm raising operation and the efficiency of silkworm raising.

[0024] For this reason, Figure 6 and 7As shown, the present embodiment is designed with a removal rod 26. Generally, two removal rods 26 are required, which are used to be placed on the lower silkworm raising frame 3 along the front-to-back direction, that is, along the width direction of the silkworm raising frame 3, and the upper silkworm raising frame 3 can be lowered onto the removal rod 26 and moved outward along the removal rod 26. Specifically, the removal rod 26 includes a rod portion 261 and two limiting portions 262 arranged below the rod portion 261, wherein the rod portion 261 is a horizontal rod and the limiting portions 262 are vertical rods. When the rod portion 261 is mounted on the lower silkworm raising frame 3 along the front-to-back direction, the two limiting portions 262 are respectively located on the opposite sides of the lower silkworm raising frame 3. In this way, the position of the entire removal rod 26 along its length direction is relatively stably limited. Regardless of whether the upper silkworm raising frame is moved outward along the rod portion 261 or moved back into the supporting frame 1, the removal rod 262 will not be driven to move by the friction between the silkworm raising frame 3 and the rod portion 261, thereby avoiding the removal rod 26 from moving forward and falling into the lower silkworm raising frame 3, affecting the silkworms in the lower silkworm raising frame 3. In addition, it is necessary to move at least most of the silkworm raising frame 3 out before it is convenient to lift it out manually or clean the silkworm feces. Therefore, the moving-out rod 26 needs to extend outward by a certain length to effectively support the silkworm raising frame 3 to move out a sufficient distance. When the silkworm raising frame 3 is moved outward by a certain distance, since there is no support below the end of the moving-out rod 26 extending outward, the overall center of gravity of the moving-out rod 26 and the silkworm raising frame 3 above is outward, the other end of the moving-out rod is easy to warp up, and the silkworm raising frame 3 is easy to tip over. For this reason, it is necessary to at least limit the upward warping of the end of the moving-out rod 26 opposite to the moving-out direction of the silkworm raising frame 3. A limiting rod 263 facing the moving-out direction of the silkworm raising frame 3 can be set at the limiting portion 262 at this end of the moving-out rod 26, and the limiting rod 263 is extended to the bottom of the silkworm raising frame 3 to prevent this end from warping up. In order to facilitate the coordination between the removal rod 26 and the silkworm raising frame 3, the distance between the limiting rod 263 on the limiting part 262 at one end and the limiting part 262 at the other end can be designed to be greater than the width of the silkworm raising frame 3 in this direction. When in use, the rod part 261 is first placed on the silkworm raising frame 3 below, and then the removal rod 26 is pulled in the removal direction of the silkworm raising frame 3, and the limiting rod 263 will extend to the bottom of the silkworm raising frame 3 to achieve effective limiting. At the same time, since the friction force on the removal rod 26 during the removal of the upper silkworm raising frame 3 is also the same as the direction in which the limiting rod 263 extends to the bottom of the silkworm raising frame, the removal action of the silkworm raising frame 3 can effectively ensure that the limiting rod 263 is stably located below the silkworm raising frame, maintaining a reliable limiting effect. In the process of moving the external silkworm raising frame 3 back into the supporting frame 1, since the overall center of gravity of the removal rod 26 and the silkworm raising frame 3 moves inward, the stability of the support is guaranteed. Even if the limiting rod 263 loses its limiting effect, the silkworm raising frame will not tip over.

[0025] In the process of silkworm rearing, the upper cluster is an important stage for the silkworms to spin silk into cocoons. In order to improve the convenience and efficiency of the upper cluster, the present embodiment designs an upper cluster structure, such as Figure 8 and9 As shown, it includes an upper cluster frame 19 and an upper cluster frame cross bar 18. According to the height requirement, two opposite upper cluster frame cross bars 18 are assembled above each silkworm raising frame 3 through a lifting chain 10, so that multiple upper cluster frames 19 can be mounted on the two upper cluster frame cross bars 18 along the length direction. Since the four lifting chains 10 are located at the four corners of the support frame 1, if the upper cluster frame cross bars 18 are directly installed on the lifting chains 10, the distance between the two upper cluster frame cross bars 18 will be larger. After the upper cluster frame 19 is mounted on the two upper cluster frame cross bars 18, its two ends will exceed the support frame 1 and be easily affected by the outside world. Therefore, the present embodiment designs a transition rod 27, which is connected to the two lifting chains 10 along the width direction of the support frame 1 through the third articulated buckle. The transition rod 27 can be a round tube with a smaller diameter, which can be directly passed through the third articulated buckle to achieve assembly, and can be directly pulled out during disassembly, which is convenient to operate. In this way, the four lifting chains 10 are connected to the left and right transition rods 27, and then the upper cluster frame cross bar 18 is hung between the two transition rods 27 using the hook 14. The hook is S-shaped, with the upper end hung on the transition rod 27 and the lower end hooked into the through hole at the end of the upper cluster frame cross bar 18. This also makes it easier to adjust the distance between the two upper cluster frame cross bars 18 to adapt to the length of the upper cluster frame 19.

[0026] like Fig.10 and 11 As shown, the upper cluster frame 19 includes a grid cluster 191 and an adjustment seat 192. A rotating shaft 193 is provided at opposite ends of the grid cluster 191. A rotating shaft hole is provided at the end of the adjustment seat 192. A locking hole and a locking bolt 194 connected to the rotating shaft hole are provided on the side of the adjustment seat 192. Among them, the grid cluster 191 can adopt a paper grid cluster, which is lighter in weight. The four sides are bound with shelf strips to form a stable frame structure. The middle part of the two ends of the grid cluster 191 in the length direction is fixedly connected with a rotating shaft 193. The rotating shaft 193 at both ends is rotatably connected to the adjustment seat 192, and the rotating shaft is supported by the locking bolt 194 to lock the inclination angle of the grid cluster 191. The two adjustment seats 192 are respectively placed on two upper cluster frame cross bars 18. The adjustment seat 192 can be made of a rectangular wooden block. On the one hand, it is easy to process and has low cost. On the other hand, the wooden block has a better friction coefficient and can maintain the position stability of the adjustment seat 192 on the upper cluster frame cross bar 18. As shown Fig.12 As shown, in order to further ensure the position stability of the adjustment seat 192 placed on the upper cluster frame cross bar 18, a positioning groove can be set at the lower part of the adjustment seat 192 to cooperate with the upper cluster frame cross bar 18 to limit the radial movement of the adjustment seat 192 along the upper cluster frame cross bar 18.

[0027] In order to facilitate the adjustment of the distance between the upper cluster frame 19 and the silkworm raising frame 3 and ensure the efficient upper clustering, a plurality of positioning pin holes 5 are provided on the four uprights of the support frame 1 along the height direction thereof, and a positioning pin 13 for positioning the height position of the silkworm raising frame 3 is provided in the pin hole 5. When in use, the positioning pin 13 can be inserted under the silkworm raising frame 3 through the positioning pin hole 5, and then the hanging rope 4 is gradually released, and the silkworm raising frame 3 is supported at the positioning pin 13 and stops descending, at which time the upper cluster frame 19 can continue to descend until the distance between it and the silkworm raising frame 3 reaches the requirement and stops descending.

[0028] The specific method of using the upper cluster structure is as follows: first lower the highest layer of the silkworm raising frame 3 to an appropriate height. At this time, the lifting chain 10 between the silkworm raising frame 3 on this layer and the balance bar 6 is in a stretched state and has sufficient operating space. The third articulated buckle for installing the transition rod 27 can be installed on the lifting chain 10 in advance. At this time, it is only necessary to pass the transition rod 27 through the two third articulated buckles to achieve installation. After the left and right transition rods 27 are installed, two upper cluster frame cross bars 18 are hung between the two transition rods 27 through the hooks 14, and then the required number of upper cluster frames 19 are evenly placed on the two upper cluster frame cross bars 18 in turn, and the grid cluster 191 is adjusted to a 45° inclination. Of course, it can also be other angles. The purpose is to ensure that the grid cluster 191 will not collide with the silkworm raising frame 3 during the rising process on the one hand, and to avoid collisions between adjacent grid clusters 191 on the other hand. Therefore, the inclination angle should not be too large or too small. Next, the silkworm rack 3 with the upper cluster frame 19 arranged on that layer is raised, and the silkworm rack 3 on the second layer is raised to an appropriate height. At this time, the lifting chain 10 between the silkworm rack 3 on this layer and the silkworm rack 3 on the highest layer is in a stretched state. Repeat the above operation to install the upper cluster frame. Similarly, complete the installation of the upper cluster frame above each layer of silkworm racks 3. At this time, the entire lifting chain 10 is in a stretched state, and the distance between the grid cluster 191 and the silkworm rack 3 cannot meet the requirements of the upper cluster. Insert four positioning pins 13 under each layer of silkworm racks 3, and then make all the silkworm racks 3 descend synchronously. Due to the pre-designed distance and position, all the silkworm racks 3 can reach the positioning pins 13 below them at the same time and be supported. At this time, continue to make the lifting chain 10 descend, and the upper cluster frame 19 on each layer will continue to descend and gradually approach the silkworm rack 3 on this layer until it reaches the required distance and stops descending. Then adjust the inclination angle of the grid cluster 191 to 70° (the angle with the horizontal direction), as shown in FIG. Figure 8As shown, on the one hand, the lower end of the square cluster 191 is closer to the silkworm rearing frame 3 to facilitate the silkworms to climb onto the cocoon. On the other hand, the inclination angle allows the feces produced by the silkworms during the climbing process to naturally fall onto the silkworm rearing frame 3, ensuring the quality of the cocoons. Due to the habit of silkworms, they like to climb to higher places when climbing onto the cocoon. Therefore, the upper part of the square cluster 191 will be occupied first, while the lower part of the square cluster 191 will always be empty. In order to improve the efficiency of climbing onto the cocoon, it is necessary to invert the square cluster 191 in the middle of the process. Since the distance between the square cluster 191 and the silkworm rearing frame 3 is relatively close at this time, if the square cluster 191 is directly rotated, it is easy to collide with the silkworm cocoon. Therefore, it is necessary to first pull the lifting chain 10 upward to straighten the lifting chain 10, so that the distance between each layer of the square cluster 191 and the silkworm rearing frame 3 can be increased, and then flip the square cluster 191 to swap the upper and lower ends, that is, the empty squares are at the top, as shown in FIG. Fig. 9 As shown, the distance between the square cluster 191 and the silkworm raising frame 3 is then adjusted, and the upper cluster is continued. After the cocooning is completed, the upper cluster frame 19 at a lower height can be taken out first, and the upper cluster frame cross bar 18 and transition bar 27 at the corresponding position can be disassembled, and then the lifting chain 10 is pulled upward to make the lifting chain 10 straight, that is, the silkworm raising frame 3 is separated from the support of the positioning pins 13, and all the positioning pins 13 are pulled out, and then the silkworm raising frame 3 is gradually lowered, and the layer where the upper cluster frame 19 has not been removed is disassembled layer by layer from bottom to top.
