Description

Technical Field

[0001] This utility model relates to the field of silkworm rearing equipment technology, and in particular to a lifting multi-layer silkworm rearing equipment. Background Technology

[0002] Currently, to save space and improve silkworm rearing efficiency and quality, farmers often use multi-layered silkworm rearing equipment. For ease of operation, these multi-layered silkworm racks are designed to be height-adjustable. For example, Chinese invention patent application number 202311554041.0 discloses a silkworm rearing device with adjustable rack height, including a vertically mounted support frame with several horizontally arranged racks. The racks are arranged sequentially from top to bottom along the support frame. A lifting mechanism is connected to the top of the support frame, and a flexible structure connects the lifting mechanism to the racks. The upper end of the flexible structure is connected to the lifting mechanism, and the lower end is connected to each rack.

[0003] Although the silkworm racks of the aforementioned silkworm rearing equipment can be raised and lowered, they still cannot balance the convenience of silkworm rearing operations with the efficiency of silkworm rearing. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide a lifting multi-layer silkworm rearing device that can effectively balance the convenience of silkworm rearing operation and silkworm rearing efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A lifting-type multi-layer silkworm rearing device includes a support frame, a lifting drive mechanism on the support frame, multiple lifting chains at the output end of the lifting drive mechanism, and multiple silkworm rearing frames detachably connected to the multiple lifting chains at intervals. It also includes at least two removal rods, each removal rod including a rod portion and two limiting portions located below the rod portion. When the rod portion spans across the lower silkworm rearing frame, the upper silkworm rearing frame can be moved out along the upper side of the rod portion. The two limiting portions prevent the removal rod from moving with the upper silkworm rearing frame by cooperating with the side of the lower silkworm rearing frame. One limiting portion on the side opposite to the direction of movement of the upper silkworm rearing frame prevents the removal rod from tilting upwards.

[0007] Preferably, the silkworm rearing frame has a limiting hole on its side, and at least one of the limiting parts has a limiting rod that can be inserted into the limiting hole to prevent the removal rod from tilting upwards.

[0008] Preferably, the output end of the lifting drive mechanism is provided with a balance bar, and the support frame is provided with balance bars on both opposite sides, with the lifting chain provided at both ends of the balance bar.

[0009] Preferably, the support frame includes four columns, and each of the opposite sides of the silkworm rearing frame is provided with an openable anti-sway device, which wraps around the columns when closed.

[0010] Preferably, the closable anti-sway device includes a mounting plate, a first opening and closing plate horizontally rotatably connected to one end of the mounting plate, a fixed rod located at the other end of the mounting plate, and a second opening and closing plate vertically rotatably connected to the fixed rod. The upper part of the first opening and closing plate and the lower part of the second opening and closing plate are provided with matching locking slots.

[0011] Preferably, the system includes an upper cluster frame and an upper cluster frame crossbar. The upper cluster frame crossbar is detachably connected between the two lifting chains. Each silkworm rearing frame has two upper cluster frame crossbars on opposite sides above it, and multiple upper cluster frames are placed on two upper cluster frame crossbars of the same height.

[0012] Preferably, two opposite transition rods are provided at the same height position of the multiple lifting chains. The transition rods abut against the inner side of the support frame, and the two ends of the upper frame crossbar are respectively hung on the two transition rods by hooks.

[0013] Preferably, the upper cluster frame includes a grid cluster and an adjustment seat. The grid cluster has a rotating shaft at both opposite ends, the adjustment seat has a rotating shaft hole at the end, and the adjustment seat has a locking hole and a locking bolt connected to the rotating shaft hole on the side.

[0014] Preferably, the adjusting seat is provided with a positioning groove that matches the crossbar of the upper cluster frame.

[0015] Preferably, the support frame is provided with a plurality of positioning pin holes along its height direction, and positioning pins for positioning the height position of the silkworm rearing frame are provided in the pin holes.

[0016] The advantages of this utility model are:

[0017] 1. The design of the removal rod facilitates the removal of the silkworm rearing frame, improving the ease of operation of the silkworm trays inside the frame, such as cleaning silkworm excrement and transferring silkworms. At the same time, the removal rod is easy and quick to assemble and disassemble, and has high support stability. Therefore, larger silkworm trays can be used for silkworm rearing, resulting in higher silkworm rearing efficiency.

[0018] 2. By setting up a balance bar, the position of the lifting chain is moved to the corner of the support frame to avoid the lifting chain affecting silkworm rearing operations, such as feeding mulberry leaves and moving the silkworm rearing frame.

[0019] 3. By setting an openable and closable anti-sway device, the stability of the silkworm rearing frame during lifting and lowering is improved. At the same time, the opening and closing of the openable and closable anti-sway device is convenient and will not affect the removal of the silkworm rearing frame.

[0020] 4. Using the upper cluster frame crossbar to place the upper cluster frame makes it more convenient to pick up and put down the upper cluster frame, while using the transition bar to ensure the positional stability of the upper cluster frame crossbar;

[0021] 5. By setting an adjustment and locking structure between the grid cluster and the adjustment seat, it is easy to adjust the tilt angle of the grid cluster to meet the needs of operations such as inverting the cluster and improve the efficiency of cluster loading.

[0022] 6. The height of the silkworm rearing frame is positioned by setting positioning pin holes and positioning pins on the support frame, so as to adjust the distance between the upper cocooning frame and the silkworm rearing frame and ensure the efficiency of cocooning.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1-3 As shown, this embodiment provides a lifting multi-layer silkworm rearing device, including a support frame 1, a lifting drive mechanism mounted on the support frame 1, multiple lifting chains 10 located at the output end of the lifting drive mechanism, and multiple silkworm rearing frames 3 detachably connected to the multiple lifting chains 10 at intervals. The support frame 1 is primarily a rectangular frame composed of multiple round tubes, with support feet 2 at the bottom. The multiple round tubes are connected by first swivel buckles 7 for easy disassembly and transportation. Alternatively, the support frame 1 can be made of square tubing, and the tubes can be connected by welding. In a more specific implementation, the entire rectangular frame has an inner length of 3015 mm, an inner height of 3000 mm, and an inner width of 1500 mm. Of course, other dimensions can be designed according to actual needs. Figure 1 The view shown is the long side of the supporting frame 1. The terms "front," "back," "left," and "right" mentioned below are all based on this viewpoint.

[0037] The lifting drive mechanism is generally located at the top of the support frame 1 and mainly includes a crossbar shaft 25, a drive device 8, lifting ropes 4, and a transition guide wheel 17. The crossbar shaft 25 is located at the middle of the top of the support frame 1 along its length, with one end connected to a bearing seat 9 and the other end connected to the drive device 8. The drive device 8 can generally be a motor or a manual winch. The lifting ropes 4 are connected to the crossbar shaft 25 via two fixing devices 11. Since the lifting ropes 4 require a certain winding space when wound around the crossbar shaft 25, the two fixing devices 11 are respectively located at a certain distance from the bearing seat 9 and the drive device 8, for example, 200 mm. Each fixing device 11 has a lifting rope 4 connected to its left and right sides. When the drive device 8 is activated, all four lifting ropes 4 are wound or released synchronously to achieve synchronous lifting and lowering of the lower ends of the four lifting ropes 4. The hanging ropes 4 extend to the front and rear sides of the support frame 1 via the transition guide wheel 17 set on the long side of the top of the support frame 1, that is, the two sides in the width direction. Thus, there are two hanging ropes 4 on the front and rear sides of the support frame 1 respectively. Although the lifting chain 10 can be directly connected to the lower end of the hanging ropes 4, since the hanging ropes 4 are not at the outermost side, the lifting chain 10 will also be in front and back of the support frame 1, which is inconvenient for removing the silkworm rearing frame 3. Therefore, a horizontal balance bar 6 is connected to the lower end of the two hanging ropes 4 on the front side, and a balance bar 6 is connected to the lower end of the two hanging ropes 4 on the rear side. A lifting chain 10 is connected to both ends of each balance bar 6, so that the position of the lifting chain 10 is closer to the left and right sides of the support frame 1, and it is less likely to block the front and back of the support frame 1. On the one hand, it is easier to remove the silkworm rearing frame 3 from the front, and on the other hand, it provides more open space for operations such as feeding mulberry leaves, improving convenience.

[0038] Each lifting chain 10 can be equipped with multiple second swivel buckles 20 spaced apart along its length. The spacing is determined according to actual needs, for example, 600 mm. The distance between the second swivel buckle at the highest position and the balance bar 6 can also be 600 mm. Thus, each silkworm rearing frame 3 can be connected to the second swivel buckles 20 at the same height position on the four lifting chains 10 for installation. Correspondingly, the silkworm rearing frame 3 needs to be provided with connecting holes 14 to accommodate the second swivel buckles 20. The attached diagram shows the structure of four silkworm rearing frames 3; other numbers of silkworm rearing frames 3 can be used as needed. Because the lifting chains 10 are flexible, the four silkworm rearing frames 3 will stack together from bottom to top during descent, as shown below. Figure 1 As shown; when rising, it will rise sequentially 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 rearing frame 3 is stacked, and to provide a stable support point for the stacking of the silkworm rearing frame 3, support members 12 that are higher than the silkworm rearing frame 3 are provided at the four corners of the silkworm rearing frame 3 to support the bottom of the upper silkworm rearing frame 3.

[0039] The silkworm rearing frame 3 is mainly a rectangular structure composed of four angle steels, including side panels and a bottom support plate, to integrate or place silkworm trays internally. The aforementioned support member 12 is set on the support plate. Both the side panels and the support plate have multiple holes, partly to reduce weight and partly to facilitate connection with other structures, such as the second swivel buckle 20 on the lifting chain 10. Since the lifting chain 10 and the suspension rope 4 are both flexible structures, to ensure the stability of the silkworm rearing frame 3 during lifting and the accuracy of the position when multiple silkworm rearing frames 3 are stacked, the silkworm rearing frame 3 can be designed with a length approximately equal to the inner length of the support frame 1, while its width is slightly larger than the inner width of the support frame 1. In this way, the left and right sides of the silkworm rearing frame 3 are confined to the inside of the support frame 1, thus stabilizing the left and right positions of the silkworm rearing frame 3, and the silkworm rearing frame 3 can be removed from the front or back. To further improve the positional stability of the silkworm rearing frame 3 during the lifting and lowering process, openable anti-sway devices 16 are provided on the left and right sides of the silkworm rearing frame 3 to cooperate with the columns of the supporting frame 1 to achieve the anti-sway function. Since the left and right positions of the silkworm rearing frame 3 are already stable enough, the design of the openable anti-sway devices 16 is mainly to solve the stability of the front and rear positions of the silkworm rearing frame 3. Therefore, in order to reduce the amount of operation and facilitate the removal of the silkworm rearing frame 3, this embodiment only sets one openable anti-sway device 16 on each of the left and right sides of the silkworm rearing frame 3. The two openable anti-sway devices 16 are respectively cooperated with the two columns on the front side of the supporting frame 1. Because once the front end of the silkworm rearing frame 3 does not sway back and forth, then its whole structure will not sway back and forth. Therefore, using two openable anti-sway devices 16 can achieve a better front and rear anti-sway effect. Of course, the two openable anti-sway devices 16 can also be respectively cooperated with the two columns on the rear side of the supporting frame 1.

[0040] Specifically, such as Figure 4 and 5As shown, the closable anti-sway device 16 includes a mounting plate 161, a first opening / closing plate 162 horizontally rotatably connected to one end of the mounting plate 161, a fixing rod 163 located at the other end of the mounting plate 161, and a second opening / closing plate 164 vertically rotatably connected to the fixing rod 163. The upper part of the first opening / closing plate 162 and the lower part of the second opening / closing plate 164 are provided with matching locking slots 165. The rotatable connection structure between the mounting plate 161 and the first opening / closing plate 162 can be achieved using an extended hinge, where the two leaf plates of the hinge serve as the mounting plate 161 and the first opening / closing plate 162, respectively. The mounting plate 161 can be connected to the side of the silkworm rearing frame 3 via bolts or other means. The fixing rod 163 can be bolted. During installation, first, the second opening plate 164 is fitted onto the fixing rod 163. Then, a nut is screwed onto the fixing rod 163, passing through the mounting plate 161 and the side of the silkworm rearing frame 3. Another nut is screwed on, thus using two nuts to lock the mounting plate 161 and the silkworm rearing frame 3, which also achieves the installation of the fixing rod 163 itself. In use, first, rotate the first opening plate 162 until it is close to the side of the column. Then, rotate the second opening plate 164 from top to bottom and fasten it onto the first opening plate 162. The locking holes 165 of the two opening plates interlock, thereby closing the entire openable anti-sway device 16. At this time, the openable anti-sway device 16 wraps around the column to achieve the anti-sway function. The fixing rod 163 and the first opening plate 162 are respectively engaged with the front and rear sides of the column, which plays the role of front and rear anti-sway function. Before removing the silkworm rearing frame 3, first rotate the second opening plate 164 upwards to disengage it from the first opening plate 162. Then, rotate the first opening plate 162 until it is close to the side of the silkworm rearing frame 3, thus opening the closable anti-sway device 16. Since the fixing rod 163 is fixed, to avoid interference between the fixing rod 163 and the column during the removal of the silkworm rearing frame 3, the fixing rod 163 needs to be placed on the outside of the support frame 1, and the silkworm rearing frame 3 is removed from that side. For example, in this embodiment, the closable anti-sway device 16 is designed to work with the front column. Therefore, the fixing rod 163 needs to be placed on the front side of the column, and the silkworm rearing frame 3 is removed from the front side, so the fixing rod 163 will not interfere with the column.

[0041] As mentioned in the background section, existing lifting-type silkworm rearing equipment has a large and heavy silkworm rack, making it difficult to remove directly. Removing the upper rack can easily crush the silkworms inside the lower rack. Therefore, the rack must be raised to a suitable position before cleaning the silkworm trays from the outside of the equipment, which is inconvenient and inefficient. Reducing the size and weight of the rack would decrease the number of silkworms raised, affecting rearing efficiency. Therefore, existing lifting-type silkworm rearing equipment cannot simultaneously achieve both ease of operation and high efficiency.

[0042] Therefore, such as Figure 6 and 7As shown, this embodiment is designed with a removal rod 26. Generally, two removal rods 26 are needed. They are used to support the lower silkworm rearing frame 3 in the front-to-back direction, that is, along the width direction of the silkworm rearing frame 3. The upper silkworm rearing 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 located below the rod portion 261. The rod portion 261 is a horizontal rod, while the limiting portions 262 are vertical rods. When the rod portion 261 is placed on the lower silkworm rearing frame 3 in the front-back direction, the two limiting portions 262 are located on opposite sides of the lower silkworm rearing frame 3. In this way, the position of the entire removal rod 26 along its length is relatively stably limited. Whether the upper silkworm rearing frame moves outward along the rod portion 261 or moves back into the support frame 1, the removal rod 262 will not be moved by the friction between the silkworm rearing frame 3 and the rod portion 261. This avoids the removal rod 26 from moving forward and falling into the lower silkworm rearing frame 3, which would affect the silkworms in the lower silkworm rearing frame 3. In addition, at least most of the silkworm rearing frame 3 needs to be moved out before it can be easily lifted out manually or cleaned of silkworm excrement. Therefore, the moving rod 26 needs to extend outward to a certain length to effectively support the silkworm rearing frame 3 to move out a sufficient distance. However, after the silkworm rearing frame 3 has moved outward to a certain distance, since there is no support below the outward-extending end of the moving rod 26, the overall center of gravity of the moving rod 26 and the silkworm rearing frame 3 above it is outward, and the other end of the moving rod is prone to tilting upward, making the silkworm rearing frame 3 prone to tipping over. Therefore, it is necessary to at least limit the upward tilting of the end of the moving rod 26 opposite to the direction of the silkworm rearing frame 3. A limiting rod 263 facing the direction of the silkworm rearing frame 3 can be set at the limiting part 262 at this end of the moving rod 26. By extending the limiting rod 263 under the silkworm rearing frame 3, the upward tilting of this end can be prevented. To facilitate the coordination between the removal rod 26 and the silkworm rearing frame 3, the distance between the limiting rod 263 on one end of the limiting part 262 and the limiting part 262 on the other end can be designed to be greater than the width of the silkworm rearing frame 3 in that direction. In use, the rod part 261 is first placed on the lower silkworm rearing frame 3, and then the removal rod 26 is pulled in the direction of the removal of the silkworm rearing frame 3. The limiting rod 263 will then extend to the bottom of the silkworm rearing frame 3 to achieve effective limiting. At the same time, since the friction force of the upper silkworm rearing frame 3 on the removal rod 26 during the removal process is also in the same direction as the limiting rod 263 extending to the bottom of the silkworm rearing frame, the removal action of the silkworm rearing frame 3 can effectively ensure that the limiting rod 263 is stably located under the silkworm rearing frame, maintaining a reliable limiting effect. During the process of moving the external silkworm rearing frame 3 back into the support frame 1, the overall center of gravity of the removal rod 26 and the silkworm rearing frame 3 moves inward, thus ensuring the stability of the support. Even if the limiting rod 263 loses its limiting function, the silkworm rearing frame will not tip over.

[0043] In the silkworm rearing process, the cocooning stage is a crucial step in the final silkworm spinning of its cocoon. To improve the convenience and efficiency of cocooning, this embodiment designs a cocooning structure, such as... Figure 8 and9 As shown, the system includes upper cluster frames 19 and upper cluster frame crossbars 18. Based on height requirements, two opposing upper cluster frame crossbars 18 are mounted above each silkworm rearing frame 3 via lifting chains 10. This allows multiple upper cluster frames 19 to be mounted along the length of the two upper cluster frame crossbars 18. Since the four lifting chains 10 are located at the four corners of the support frame 1, if the upper cluster frame crossbars 18 are directly installed on the lifting chains 10, the distance between the two upper cluster frame crossbars 18 will be large. After the upper cluster frames 19 are mounted on the two upper cluster frame crossbars 18, both ends will extend beyond the support frame 1, making them susceptible to external influences. Therefore, this embodiment designs a transition rod 27. The transition rod 27 is connected to two lifting chains 10 along the width direction of the support frame 1 via a third snap-fit. The transition rod 27 can be a round tube with a small diameter, which can be directly passed through the third snap-fit ​​for assembly. It can be easily pulled out for disassembly. In this way, the four lifting chains 10 are connected to the left and right transition rods 27. Then, the upper cluster frame crossbar 18 is hung between the two transition rods 27 using a hook 14. The hook is S-shaped, with the upper end hanging on the transition rod 27 and the lower end hooked into the through hole at the end of the upper cluster frame crossbar 18. This also makes it easier to adjust the distance between the two upper cluster frame crossbars 18 to accommodate the length of the upper cluster frame 19.

[0044] like Figure 10 and 11 As shown, the upper cluster frame 19 includes a grid cluster 191 and an adjusting seat 192. The grid cluster 191 has rotating shafts 193 at both opposite ends, and the adjusting seat 192 has rotating shaft holes at its ends. The adjusting seat 192 has locking holes and locking bolts 194 on its sides that connect to the rotating shaft holes. The grid cluster 191 can be made of paper, making it lighter. Its four sides are bound together with frame strips to form a stable frame structure. Rotating shafts 193 are fixedly connected to the middle of both ends of the grid cluster 191 along its length. These rotating shafts 193 are rotatably connected to the adjusting seats 192, and the locking bolts 194 hold the rotating shafts in place to lock the tilt angle of the grid cluster 191. The two adjusting seats 192 are respectively placed on two upper cluster frame crossbars 18. The adjusting seats 192 can be made of rectangular wooden blocks, which are easy to process and low in cost. Furthermore, wood has a good coefficient of friction, which helps maintain the positional stability of the adjusting seats 192 on the upper cluster frame crossbars 18. Figure 12 As shown, in order to further ensure the positional stability of the adjusting seat 192 placed on the upper cluster frame crossbar 18, a positioning groove can be provided at the lower part of the adjusting seat 192 to cooperate with the upper cluster frame crossbar 18, so as to limit the radial movement of the adjusting seat 192 along the upper cluster frame crossbar 18.

[0045] To facilitate adjustment of the distance between the upper clustering frame 19 and the silkworm rearing frame 3 and ensure efficient clustering, the four uprights of the support frame 1 are provided with multiple positioning pin holes 5 along their height direction. Positioning pins 13, which are used to position the silkworm rearing frame 3 at different heights, are installed within the pin holes 5. In use, the positioning pins 13 can be inserted under the silkworm rearing frame 3 through the positioning pin holes 5. Then, the hanging rope 4 is gradually released. The silkworm rearing frame 3 descends until it is supported by the positioning pins 13 and stops descending. At this point, the upper clustering frame 19 can continue to descend until the required distance between it and the silkworm rearing frame 3 is reached, at which point it stops descending.

[0046] The specific usage method of the upper cluster structure is as follows: First, lower the highest layer of silkworm rearing frame 3 to an appropriate height. At this time, the lifting chain 10 between the silkworm rearing frame 3 and the balance bar 6 is taut and has sufficient operating space. The third movable buckle of the transition bar 27 can be pre-installed on the lifting chain 10. At this time, it is only necessary to pass the transition bar 27 through the two third movable buckles to achieve installation. After both the left and right transition bars 27 are installed, hang the two upper cluster frame crossbars 18 between the two transition bars 27 through the hook 14. Then, place the required number of upper cluster frames 19 evenly on the two upper cluster frame crossbars 18 in sequence, and adjust the square clusters 191 to tilt at 45°. Of course, other angles are also possible. The purpose is to ensure that the square clusters 191 will not collide with the silkworm rearing frame 3 during the rising process, and to avoid collisions between adjacent square clusters 191. Therefore, the tilt angle should not be too large or too small. Next, the silkworm rearing frame 3 with the upper clustering frame 19 arranged on this layer is raised, and the second layer of silkworm rearing frame 3 is raised to an appropriate height. At this time, the lifting chain 10 between this layer of silkworm rearing frame 3 and the highest layer of silkworm rearing frame 3 is in a taut state. The above operation is repeated to install the upper clustering frame. In this way, the installation of the upper clustering frame above each layer of silkworm rearing frame 3 is completed. At this time, the entire lifting chain 10 is in a taut state, but the distance between the square clusters 191 and the silkworm rearing frame 3 is still not sufficient for the upper clustering. Four positioning pins 13 are inserted under each layer of silkworm rearing frame 3, and then all silkworm rearing frames 3 are lowered synchronously. Due to the pre-designed distance and position, all silkworm rearing frames 3 can simultaneously reach the positioning pins 13 below them and be supported. At this time, the lifting chain 10 is lowered again, and the upper clustering frame 19 on each layer will continue to descend and gradually approach the silkworm rearing frame 3 on that layer until the required distance is reached, and then the descent is stopped. Then the tilt angle of the square clusters 191 is adjusted to 70° (the angle with the horizontal direction). Figure 8As shown, this tilt angle allows the lower end of the square cluster 191 to be closer to the silkworm rearing frame 3, facilitating silkworm cocooning. Simultaneously, the tilt angle allows the excrement produced during cocooning to fall naturally onto the silkworm rearing frame 3, ensuring cocoon quality. Due to the silkworms' habits, they prefer to climb higher when cocooning, so the upper part of the square cluster 191 will be filled first, while the lower part will remain empty. To improve cocooning efficiency, the square cluster 191 needs to be rotated midway. Since the distance between the square cluster 191 and the silkworm rearing frame 3 is relatively short at this point, directly rotating the square cluster 191 could easily cause it to collide with the silkworm tray. Therefore, the lifting chain 10 needs to be pulled upwards first to taut it, increasing the distance between each layer of square cluster 191 and the silkworm rearing frame 3. Then, the square cluster 191 is rotated to reverse its position, with the empty squares on top. Figure 9 As shown, after adjusting the distance between the square cluster 191 and the silkworm rearing frame 3, continue to add clusters. After the cocoons are finished, the lower section of the upper cluster frame 19 can be removed first, and the corresponding upper cluster frame crossbar 18 and transition bar 27 can be disassembled. Then, pull the lifting chain 10 upward to straighten it, so that the silkworm rearing frame 3 is disengaged from the support of the positioning pin 13. Pull out all the positioning pins 13, and then gradually lower the silkworm rearing frame 3, disassembling the layers from bottom to top where the upper cluster frame 19 has not yet been removed.

[0047] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model.
