Description

Technical Field

[0001] This utility model belongs to the field of silkworm breeding technology, and in particular relates to a home-use mechanized and automated silkworm breeding equipment. Background Technology

[0002] Sericulture is an important part of traditional Chinese agriculture. Family-based sericulture refers to silkworm rearing activities conducted on a small scale or in a limited space. Due to the limited space, family-based sericulture often employs a three-dimensional rearing technique, stacking silkworm frames to save space and maximize efficiency. However, this technique requires unstacking and restacking individual frames for feeding or disinfection. Traditional unstacking and stacking are usually done manually, which is time-consuming, labor-intensive, and inefficient. Existing stacking and unstacking equipment is costly and requires a large area, making it unsuitable for family-based sericulture. Utility Model Content

By positioning the output end of the second reducer 152 at the upper front and the output end of the first reducer 151 at the lower front, when the input ends of the first reducer 151 and the second reducer 152 rotate in the same direction, the output ends of the first reducer 151 and the second reducer 152 connected to the upper rotating shaft 1122 rotate in opposite directions, thereby enabling the lifting frame 1127 on the first stacking unstacking mechanism 11 and the second stacking unstacking mechanism 12 to move in the same direction.

[0059] In a further embodiment, the second reducer 152 is tilted in the vertical direction so that the input end of the second reducer 152 faces the output end of the first reducer 151 behind it, so that the drive shaft 153 can be connected to the first reducer 151 and the second reducer 152.

[0060] The drive mechanism 16 includes a drive reducer 161, a drive motor 162, a drive pulley 163, a driven pulley 164, and a synchronous belt 165. The drive reducer 161 is located inside the frame 111 of the first stacking and unstacking mechanism 11, below the first reducer 151. Its input end is close to the lifting assembly 112, and its output end is located at the front. An output shaft is provided on the output end. The drive reducer 161 is an NMRV50 reducer. The drive motor 162 is connected to the input end of the drive reducer 161. The drive pulley 163 is fixedly sleeved on the output shaft of the drive reducer 161. The driven pulley 164 is fixedly sleeved on the input shaft of the first reducer 151 and is connected to the drive pulley 163 through the synchronous belt 165. The drive motor 162 starts the drive reducer 161, causing the drive pulley 163 on the output shaft of the drive reducer 161 to rotate. This rotation, via the synchronous belt 165 and the driven pulley 164, drives the output shaft at the input end of the first reducer 151 to rotate. One output end of the first reducer 151 drives the upper rotating shaft 1122 of the first stacking unstacking mechanism 11 to rotate, causing the lifting frame 1127 of the first stacking unstacking mechanism 11 to rise and fall. The other output end drives the transmission shaft 153 to rotate, which in turn drives the input shaft at the input end of the second reducer 152 to rotate. This causes the output end of the second reducer 152 to drive the upper rotating shaft 1122 of the second stacking unstacking mechanism 12 to rotate, enabling the lifting frame 1127 of the second stacking unstacking mechanism 12 to rise and fall synchronously with the lifting frame 1127 of the first stacking unstacking mechanism 11.

[0061] The stacking and unstacking device 1 further includes a conveying mechanism 17, a conveying power mechanism 18, and a telescopic mechanism 19; the conveying mechanism 17 includes a first belt conveyor 171; there are two first belt conveyors 171, which are respectively located in the lower part of the frame 111 of the first stacking and unstacking mechanism 11 and the second stacking and unstacking mechanism 12, and are slidably connected to the frame 111 through a slide table and a slide rail. The first belt conveyor 171 can move back and forth within the frame 111. The first belt conveyor 171 includes a body and a belt for conveying silkworm frames, and a drive roller is provided inside the body. The driven roller and the driven roller are connected by a belt wound around them. The driven roller and the driven roller can drive the belt to move, and the driven roller is located closer to the conveying device 2. The conveying power mechanism 18 includes a mounting frame 181, a conveying motor 182, a first conveying bearing seat 183, a first conveying shaft 184, a second conveying bearing seat 185, a second conveying shaft 186, a conveying drive sprocket 187, a conveying driven sprocket 188, and a conveying chain (not shown in the figure). The mounting frame 181 is horizontally arranged front and back in the stacking and unstacking space 3 on the side closer to the conveying device 2.

The conveyor chain (not shown in the figure) is wound around the conveyor drive sprocket 187 and the conveyor driven sprocket 188. The conveyor motor 182 drives the conveyor drive sprocket 187 to rotate, causing the conveyor chain (not shown in the figure) and the conveyor driven sprocket 188 to drive the second conveyor shaft 186 to rotate. The second conveyor shaft 186 drives the first conveyor shaft 184 to rotate synchronously. The rotation of the second conveyor shaft 186 and the first conveyor shaft 184 respectively drives the drive rollers of the two first belt conveyors 171 to rotate, causing the belt of the first belt conveyor 171 to move.

[0062] Two telescopic mechanisms 19 are provided, respectively located at the front and rear of the mounting frame 181 near the stacking space 3. Each telescopic mechanism 19 includes a telescopic cylinder 191 and a fixing member 192. The telescopic cylinder 191 is fixedly connected to the mounting frame 181 near the stacking space 3, and the piston rods of the two telescopic cylinders 191 face the two first belt conveyors 171 respectively. The fixing member 192 is fixedly mounted on the piston rods of the two telescopic cylinders 191, and is fixedly connected to the body of the first belt conveyor 171. When the piston rods of the telescopic cylinders 191 extend or retract, they can drive the first belt conveyor 171 to move back and forth within the frame 111, allowing the first belt conveyor 171 to enter or move away from the stacking space 3. When the first belt conveyor 171 enters the stacking space 3, it can send silkworm frames into the conveying device 2 or receive silkworm frames conveyed from the conveying device 2.

[0063] The conveying device 2 includes an active conveying mechanism 21 and a transition conveying mechanism 22. The active conveying mechanism 21 includes a conveying frame 211 and a second belt conveyor 212. The conveying frame 211 is vertically arranged and has multiple conveyors spaced apart on the left and right.

The transition frame 221 is horizontally arranged, with one end fixedly connected to the second belt conveyor 212 and the other end fixedly connected to the frame 111. The rollers 222 are horizontally rotatable on the transition frame 221 and are arranged in multiples at intervals.

[0066] In this invention, the start and stop of each component are controlled by a PLC control system, and sensors are set to detect the position of the silkworm frame during the stacking and unstacking process.

[0067] The working principle of this utility model is as follows:

[0068] In this embodiment, in the initial state, the left stacking / destacking device 1 is used for destacking, and the right stacking / destacking device 1 is used for stacking.

[0069] Workers send multiple silkworm frames with support legs stacked on the transport vehicle into the stacking and unstacking space 3 of the left stacking and unstacking device 1. After the multiple silkworm frames enter the stacking and unstacking space 3, the first receiving mechanism 13 and the second receiving mechanism 14 are activated, and the receiving plate enters the stacking and unstacking space 3 to hold the bottom silkworm frame. Then, the drive mechanism 16 drives the transmission mechanism 15 to make the lifting frames 1127 of the two lifting components 112 rise synchronously, so that the bottom silkworm frame and the next bottom silkworm frame (in order from bottom to top) are positioned at the corresponding support component 113, while making room for the first belt conveyor 171. After reaching its position, the piston rod of the support cylinder 1132 extends, allowing the support plate 1133 to enter the stacking and unstacking space 3. Since the silkworm frame has a structure with legs, there is a gap between the two silkworm frames. When the support plate 1133 enters the stacking and unstacking space 3, it will support the remaining silkworm frames except for the bottom silkworm frame. Then, the piston rod of the telescopic cylinder 191 of the telescopic mechanism 19 retracts, moving the two first belt conveyors 171 to the bottom of the silkworm frame, and driving the first belt conveyors 171 to run through the transmission power mechanism 18. After that, the receiving plates of the first receiving mechanism 13 and the second receiving mechanism 14 retract, no longer dragging the silkworm frame, so that the bottom silkworm frame falls onto the two first belt conveyors 171 and is sent out to the conveying device 2 through the first belt conveyors 171, completing the unstacking of the bottom silkworm frame.

[0070] Subsequently, the lifting frame 1127 moves upward, while the receiving plates of the first receiving mechanism 13 and the second receiving mechanism 14 re-enter the stacking / unstacking space 3, holding the bottommost silkworm frame among the remaining silkworm frames. Then, the support plate 1133 retracts and no longer supports the silkworm frame. The lifting frame 1127 drives the remaining silkworm frames to descend, aligning the first and second silkworm frames (from bottom to top) with the corresponding support components 113. Once in position, the support plate 1133 re-enters the stacking / unstacking space 3 to support the remaining silkworm frames except for the bottommost one. Afterward, the receiving plate retracts, and the bottommost silkworm frame falls onto the first belt conveyor 171. This process completes the unstacking of all silkworm frames.

[0071] The silkworm frames are first fed into the left transition conveyor 22 via the first belt conveyor 171, then onto the second belt conveyor 212 of the active conveyor 21, and finally into the right stacking device 1 via the right transition conveyor 22. During the conveying process, the silkworm frames can be fed and disinfected.

[0072] In the right-side stacking and destacking device 1 used for stacking, the first belt conveyor 171 of the conveying mechanism 17 is located in the stacking and destacking space 3. The first silkworm frame enters the first belt conveyor 171 of the right-side stacking and destacking device 1 from the conveying device 2. After the silkworm frame enters the designated position on the first belt conveyor 171, the first belt conveyor 171 stops conveying. The first receiving mechanism 13 and the second receiving mechanism 14 are activated, so that the receiving plate enters the stacking and destacking space 3 and supports the bottom of the silkworm frame. Then, the lifting frame 1127 moves upward, driving the silkworm frame to move upward, so that the bottom of the silkworm frame moves to the position of the corresponding support component 113. At the same time, after the silkworm frame is moved upward, the first belt conveyor 171 restarts and receives the second silkworm frame conveyed. After the silkworm frame is in place, the piston rod of the support cylinder 1132 of the support component 113 extends, so that the support plate 1133 enters the stacking and destacking space 3 to support the bottom of the silkworm frame.

[0073] Afterwards, the receiving plate is retracted, and the lifting frame 1127 moves downward, driving the first receiving mechanism 13 and the second receiving mechanism 14 to move to the bottom position of the second conveyed silkworm frame. The receiving plate re-enters the stacking space 3, supporting the bottom of the second silkworm frame. The lifting frame 1127 rises, driving the second silkworm frame to move upward. When the second silkworm frame moves upward, it will push the first silkworm frame upward. At the same time, the support plate 1133 retracts and no longer provides support. The lifting frame 1127 continues to drive the second silkworm frame to move upward, so that the bottom of the second silkworm frame moves to the position of the corresponding support component 113. Then the support plate 1133 re-enters the stacking space 3 to support the bottom of the second silkworm frame. In this way, multiple silkworm frames can be re-stacked.

[0074] After stacking is completed, the piston rod of the telescopic mechanism 19 of the stacking and unstacking device 1 on the right extends, allowing the two first belt conveyors 171 to enter the frame 111 and make room. At the same time, the receiving plates of the first receiving mechanism 13 and the second receiving mechanism 14 support the bottom of the lowest silkworm frame, the support plate 1133 of the support component 113 retracts, and the lifting frame 1127 drives the multiple silkworm frames after stacking to descend, so that the stacked silkworm frames are placed on the transport vehicle that has been placed in the stacking and unstacking space 3. Then the receiving plate is retracted, and the stacked silkworm frames can be transported away by the transport vehicle.

[0075] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
