A discharge port is located at the bottom of the brush system. The conveying mechanism transports the rearing frame from the feeding end to the discharging end, and the brush system scrapes off the cocoons from the bottom of the rearing frame. The cocoons fall through the discharge port and are collected. This invention uses a conveying mechanism to transport the rearing frame from the feeding end to the discharging end. As the frame passes the brush system, the brush system scrapes off the cocoons from the bottom of the rearing frame. The scraped cocoons fall through the discharge port and are collected. After the cocoons are scraped off, the conveying mechanism sends the rearing frame out from the discharging end, thus achieving automatic cocoon harvesting from the bottom of the rearing frame. The conveying mechanism and the brush system work together to harvest cocoons from the bottom of the rearing frame sequentially and continuously, thereby achieving continuous cocoon harvesting operations and improving rearing efficiency.

Description

Technical Field

[0001] The invention belongs to the technical field of factory breeding equipment, and in particular relates to a frame bottom cocoon picking machine. Background Art

[0002] The traditional breeding method is a family-style small workshop breeding method, which generally uses small bamboo baskets for breeding. This small bamboo basket has a simple structure, is easy to manufacture, can be woven by hand, and has low cost. Small workshop breeding is a fully artificial breeding method. From silkworm eggs to adults to cocoon collection, all are achieved through manual operation. It is time-consuming and labor-intensive, and the breeding efficiency is very low. In addition, due to seasonal conditions, silkworms can only be raised at specific times. The annual output of silkworm cocoons is extremely low, which cannot meet the needs of today's society and has been gradually eliminated by society.

[0003] In order to make up for the shortcomings of traditional workshop-style silkworm breeding, large-scale and factory-based silkworm breeding technology was born. In order to meet the requirements of large-scale breeding, breeding tools such as silkworm frames and carriers were designed. Based on these breeding tools, silkworm breeding, transfer of silkworms between different ages, and feed delivery can be realized, playing an important role in factory-based silkworm breeding technology.

[0004] The existing factory-based silkworm farming is small in scale, especially in the cocoon harvesting process. The existing cocoon harvesting methods are manual or semi-automatic. Manual cocoon harvesting is extremely slow and inefficient. Semi-automatic cocoon harvesting is difficult to operate, has a high probability of failure, and has a low efficiency.

[0005] Therefore, automated cocoon picking equipment came into being. Existing cocoon picking equipment mainly adopts extrusion, ejection and tooth-shaped methods to pick cocoons. In actual cocoon picking, it is found that these cocoon picking methods are inefficient, there are many residual cocoons in the breeding frame, and the cocoon picking effect is poor. At the same time, the existing cocoon picking equipment has fewer auxiliary parts and relatively single functions, resulting in poor use of the cocoon picking equipment. Summary of the invention

[0006] The object of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide a frame-bottom cocoon picking machine. A feeding end is arranged at one end of a frame, a discharging end is arranged at the other end of the frame, and a conveying mechanism and a brush system are arranged in the frame. The conveying mechanism conveys the breeding frame from the feeding end to the discharging end. When passing through the brush system, the cocoons at the bottom of the breeding frame are scraped off after the brush system is operated. The scraped cocoons are collected centrally after falling through a drop port. After the cocoons at the bottom of the breeding frame are scraped off, the conveying mechanism sends the breeding frame out from the discharging end, thereby realizing automatic cocoon picking at the bottom of the breeding frame. The conveying mechanism cooperates with the brush system to sequentially and continuously pick cocoons at the bottom of the breeding frame, thereby realizing continuous cocoon picking operations and improving breeding efficiency.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The frame bottom cocoon picking machine comprises: a frame; one end of the frame is a feeding end, and the other end of the frame is a discharging end; the characteristic is that: the frame is provided with a conveying mechanism, a brush system is provided inside the frame, and a drop opening is provided at the bottom of the frame for the brush system; the conveying mechanism conveys the breeding frame from the feeding end to the discharging end, and the brush system scrapes off the cocoons at the bottom of the conveyed breeding frame, and the cocoons are collected collectively after falling through the drop opening. The present invention arranges a feeding end at one end of a frame, arranges a discharging end at the other end of the frame, and arranges a conveying mechanism and a brush system in the frame. The conveying mechanism conveys the breeding frame from the feeding end to the discharging end. When passing through the brush system, the brush system scrapes off the silkworm cocoons at the bottom of the breeding frame after operation. The scraped silkworm cocoons fall through a drop port and are collected centrally. After the silkworm cocoons at the bottom of the breeding frame are scraped off, the conveying mechanism sends the breeding frame out from the discharging end, thereby realizing automatic cocoon picking at the bottom of the breeding frame. The conveying mechanism cooperates with the brush system to sequentially and continuously pick cocoons at the bottom of the breeding frame, thereby realizing continuous cocoon picking operations and improving breeding efficiency.

[0009] Furthermore, the conveying mechanism includes a chain conveyor 1, a chain conveyor 2 and a push frame assembly, the chain conveyor 1 is arranged at the feed end, the chain conveyor 2 is arranged at the discharge end, the brush system is located between the chain conveyor 1 and the chain conveyor 2, the push frame assembly is arranged in the frame, and the push frame assembly pushes the breeding frame from the chain conveyor 1 to the chain conveyor 2. The chain conveyor 1 conveys the breeding frame from the feed end to the direction of the drop port, and the push frame assembly runs at the same time, and the push frame assembly pushes the breeding frame on the chain conveyor 1 to the drop port, and the brush system scrapes off the cocoons at the bottom of the breeding frame. After the cocoons at the bottom of the breeding frame are scraped off, the push frame assembly continues to push the breeding frame to the chain conveyor 2, and the chain conveyor 2 sends the breeding frame out from the discharge end.

[0010] Furthermore, the push frame assembly includes a conveyor belt, a driving motor, a driven wheel, a driving wheel and a tensioning wheel. The driving wheel, the driven wheel and the tensioning wheel are correspondingly connected to the two sides of the frame.

A synchronous connecting rod 1 is connected between the two driving wheels. The driving motor is connected to the driving wheel on one side. The driving motor controls the rotation of the driving wheel. The driving wheel drives the conveyor belt to rotate through the driven wheel and the tensioning wheel, and the conveyor belt drives the push rod to rotate. By setting a synchronous connecting rod 1 between the two driving wheels, the driving motor is connected to the main wheel on one side. A single driving motor can control the two driving wheels to rotate synchronously. The rotation of the driving wheel drives the driven wheel and the tensioning wheel to rotate synchronously through the conveyor belt. The two conveyor belts drive the push rod to rotate at the same time, so that the push rod pushes the breeding frame to move after it is against one side of the breeding frame.

[0011] Furthermore, a synchronous link 2 is connected between the two tensioning wheels, the tensioning wheel is rotatably connected to the synchronous link 2, and both ends of the synchronous link 2 are provided with adjustment components, which are used to adjust the tensioning position, thereby adjusting the tension of the conveyor belt. The adjustment component drives the two tensioning wheels to adjust their positions through the synchronous link 2, thereby adjusting the tension of the conveyor belt.

[0012] Furthermore, the adjustment assembly includes an adjustment frame, an adjustment block and an adjustment screw. The two ends of the synchronous connecting rod 2 are respectively rotatably connected to the adjustment block. Both sides of the adjustment frame are provided with slide rails. The corresponding two sides of the adjustment block are slidably connected to the slide rails. One end of the adjustment screw passes through the adjustment frame and is connected to the adjustment block. Both ends of the adjustment screw are provided with adjustment nuts, which are tightened on the adjustment frame. By loosening the adjustment nut, the adjustment screw is driven to drive the adjustment block to slide along the slide rail, so that the adjustment block drives the synchronous connecting rod 2 and the tensioning wheel to slide along the direction of the slide rail, thereby adjusting the tension of the conveyor belt.

[0013] Furthermore, a pressing frame assembly is provided in the frame corresponding to the brush system, and the pressing frame assembly is against the top of the breeding frame. The conveying direction of the breeding frame is from the feed end to the discharge end, and the rotation direction of the brush system is to rotate toward the feed end. The rotation direction of the brush system is opposite to the conveying direction of the breeding frame, so that the cocoons at the bottom of the breeding frame can be better scraped off. The conveying resistance of the breeding frame is too large, and the breeding frame is conveyed by cooperating with the push frame assembly to ensure that the breeding frame can be conveyed to the discharge end. However, the breeding frame is easily lifted up, resulting in a reduction in the contact surface between the breeding frame and the brush system. The pressing frame assembly is provided so that the pressing frame assembly presses down the breeding frame, thereby ensuring the contact surface between the brush system and the breeding frame, thereby ensuring that the cocoons at the bottom of the breeding frame can be completely scraped off.

The rotating seat is rotatably connected to one end of the electric push rod. The fixed seat is fixedly connected to the two side walls in the frame, and the top of the pressure strip is rotatably connected to one end of the rotating arm. The other end of the rotating arm is rotatably connected to the fixed seat. The other end of the electric push rod is rotatably connected to the middle of the rotating arm. The telescopic control of the electric push rod swings the rotating arm, so that the rotating arm drives the pressure strip to rise and fall, and the pressure strip is against the top of the breeding frame. The support seat is used to install the electric push rod, and the fixed seat is used to install the pressure strip. The telescopic drive of the electric push rod drives the rotating arm to swing, and the swing of the rotating arm drives the pressure strip to rise and fall, so that the pressure strip can be pressed against the top of the breeding frame, ensuring that the breeding frame and the brush system can be fully in contact, so that the cocoons at the bottom of the breeding frame can be completely scraped off.

[0015] Furthermore, a first conveyor belt is provided below the feed end, and the first conveyor belt is provided below the conveying mechanism, and the first conveyor belt conveys the cocoons from the feed end to the discharge end. Before the breeding frame with the cocoons is conveyed to the discharge port, due to the vibration during the conveying process of the breeding frame, the stability of the cocoons at the bottom of the breeding frame cannot be guaranteed. By providing the first conveyor belt below the feed end, the cocoons that fall off the bottom of the breeding frame automatically fall onto the first conveyor belt, and the first conveyor belt conveys the automatically fallen cocoons to the discharge port.

[0016] Furthermore, a first swinging assembly is provided at one end of the first conveyor belt near the material drop opening, and the first swinging assembly controls the end of the first conveyor belt near the material drop opening to swing downward, thereby buffering the falling of the cocoons.

After the brush system scrapes the cocoons at the bottom of the breeding frame, the breeding frame is transported to the second chain conveyor through the push frame assembly, and the second chain conveyor transports the breeding frame to the discharge end. There are cocoons remaining at the bottom of the breeding frame.

By providing a second conveyor belt below the discharge end, the cocoons remaining in the breeding frame fall onto the second conveyor belt, and the second conveyor belt transports the cocoons to the side of the drop port.

[0019] Furthermore, the second conveyor belt is provided with a second swinging assembly corresponding to the drop-out port, and the second swinging assembly controls the end of the second conveyor belt near the drop-out port to swing downward, thereby buffering the falling of the cocoons, and the height of the end of the second conveyor belt near the drop-out port is higher than the height of the end of the first conveyor belt near the drop-out port. The second swinging assembly controls the end of the second conveyor belt near the drop-out port to swing downward, so that the cocoons can slide along the second conveyor belt to the first conveyor belt, and then slide from the first conveyor belt, avoiding the cocoons from falling directly from the second conveyor belt, thereby avoiding the cocoons from falling and being damaged, and ensuring the safety of the cocoons.

[0023] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0024] The present invention arranges a feeding end at one end of a frame, arranges a discharging end at the other end of the frame, and arranges a conveying mechanism and a brush system in the frame. The conveying mechanism conveys the breeding frame from the feeding end to the discharging end. When passing through the brush system, the brush system scrapes off the silkworm cocoons at the bottom of the breeding frame after operation. The scraped silkworm cocoons fall through a drop port and are collected centrally. After the silkworm cocoons at the bottom of the breeding frame are scraped off, the conveying mechanism sends the breeding frame out from the discharging end, thereby realizing automatic cocoon picking at the bottom of the breeding frame. The conveying mechanism cooperates with the brush system to sequentially and continuously pick cocoons at the bottom of the breeding frame, thereby realizing continuous cocoon picking operations and improving breeding efficiency.

By setting a synchronous connecting rod 1 between the two driving wheels, the driving motor is connected to the main wheel on one side. A single driving motor can control the two driving wheels to rotate synchronously.

After the cocoons at the bottom of the breeding frame are scraped off, the push frame assembly 9 continues to push the breeding frame to the chain conveyor 2 8, and the chain conveyor 2 8 sends the breeding frame out from the discharge end 3.

[0040] The push frame assembly 9 includes a conveyor belt 10, a drive motor 11, a driven wheel 12, a driving wheel 13 and a tensioning wheel 14. The driving wheel 13, the driven wheel 12 and the tensioning wheel 14 are all rotatably connected on both sides of the frame 1. The conveyor belt 10 is rotatably connected between the driving wheel 13, the driven wheel 12 and the tensioning wheel 14 on one side of the frame 1. A push rod 15 is connected between the two conveyor belts 10. A synchronous connecting rod 16 is connected between the two driving wheels 13. The drive motor 11 is connected to the driving wheel 13 located on one side. The drive motor 11 controls the rotation of the driving wheel 13. The driving wheel 13 drives the conveyor belt 10 to rotate through the driven wheel 12 and the tensioning wheel 14, and the conveyor belt 10 drives the push rod 15 to rotate. By setting a synchronous connecting rod 16 between the two driving wheels 13, the driving motor 11 is connected to the main wheel on one side. The single driving motor 11 can control the two driving wheels 13 to rotate synchronously. The rotation of the driving wheel 13 drives the driven wheel 12 and the tensioning wheel 14 to rotate synchronously through the conveyor belt 10. The two conveyor belts 10 simultaneously drive the push rod 15 to rotate, so that the push rod 15 pushes the breeding frame to move after it contacts one side of the breeding frame.

By loosening the adjustment nut 23, the adjustment screw 21 is driven to drive the adjustment block 20 to slide along the slide rail 22, so that the adjustment block 20 drives the synchronous link 17 and the tensioning wheel 14 to slide along the direction of the slide rail 22, thereby adjusting the tension of the conveyor belt 10.

[0043] A pressing frame assembly 24 is provided in the frame 1 corresponding to the brush system 5, and the pressing frame assembly 24 is against the top of the breeding frame. The conveying direction of the breeding frame is from the feed end 2 to the discharge end 3, and the rotation direction of the brush system 5 is to rotate toward the feed end 2. The rotation direction of the brush system 5 is opposite to the conveying direction of the breeding frame, so that the cocoons at the bottom of the breeding frame can be scraped off better. The conveying resistance of the breeding frame is too large, and the breeding frame is conveyed by cooperating with the push frame assembly 9 to ensure that the breeding frame can be conveyed to the discharge end 3. However, the breeding frame is easily lifted up, resulting in a decrease in the contact surface between the breeding frame and the brush system 5. The pressing frame assembly 24 is set so that the pressing frame assembly 24 presses down the breeding frame, thereby ensuring the contact surface between the brush system 5 and the breeding frame, thereby ensuring that the cocoons at the bottom of the breeding frame can be completely scraped off.

The telescopic control of the electric push rod 29 controls the swing of the rotating arm 28, so that the rotating arm 28 drives the pressure strip 25 to rise and fall, and the pressure strip 25 is against the top of the breeding frame. The support seat 26 is used to install the electric push rod 29, and the fixed seat 27 is used to install the pressure strip 25. The extension and retraction of the electric push rod 29 drives the rotating arm 28 to swing, and the swing of the rotating arm 28 drives the pressure strip 25 to rise and fall, so that the pressure strip 25 can be pressed tightly on the top of the breeding frame, ensuring that the breeding frame and the brush system 5 can be in full contact, so that the cocoons at the bottom of the breeding frame can be completely scraped off.

[0045] A first conveyor belt 31 is provided below the feed end 2. The first conveyor belt 31 is provided below the conveying mechanism 4. The first conveyor belt 31 conveys the cocoons from the feed end 2 to the discharge end 3. Before the breeding frame with the cocoons is transported to the drop port, due to the vibration during the transportation of the breeding frame, the stability of the cocoons at the bottom of the breeding frame cannot be guaranteed. By providing the first conveyor belt 31 below the feed end 2, the cocoons that fall off the bottom of the breeding frame automatically fall onto the first conveyor belt 31, and the first conveyor belt 31 transports the automatically fallen cocoons to the drop port.

[0046] The first conveyor belt 31 is provided with a first swinging assembly 32 at one end near the material drop opening, and the first swinging assembly 32 controls the first conveyor belt 31 to swing downward at one end near the material drop opening, so as to cushion the falling of the cocoons. The first swinging assembly 32 controls the first conveyor belt 31 to swing downward at one end near the material drop opening, so that the cocoons can slide along the first conveyor belt 31, thereby preventing the cocoons from falling directly from the first conveyor belt 31, thereby preventing the cocoons from falling and being damaged, and ensuring the safety of the cocoons.
