Description

Technical Field

[0001] The present invention relates to the technical field of sericulture breeding, and particularly relates to a mulberry leaf adding device. Background Art

[0002] During the process of raising silkworms, evenly putting mulberry leaves into the silkworm trays is an important step in sericulture. This process requires a large amount of manual labor, with high manual operation intensity and low efficiency. Therefore, there is an urgent need for an automated machine to replace manual labor. In the prior art, there are devices that can add the mulberry leaves piled on the ground into the hopper, but there are few devices that can quantitatively add the mulberry leaves in the hopper into the silkworm trays. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a mulberry leaf adding device to solve the problem that it is difficult to quantitatively add mulberry leaves into the silkworm trays in the prior art.

[0004] The present invention is realized through the following technical solutions:

[0005] A mulberry leaf adding device includes a frame and a control unit. A mulberry leaf feeding tray, a weighing sensor, and a material receiving frame with through upper and lower ends are provided on the frame. A liftable bottom is provided in the material receiving frame. The mulberry leaf feeding tray is arranged on one side of the upper opening of the material receiving frame. A feeding brush is provided at the upper opening of the material receiving frame. The rotation of the feeding brush can send the mulberry leaves contained in the material receiving frame into the mulberry leaf feeding tray. The weighing sensor is used to measure the load of the mulberry leaf feeding tray. The control unit is configured to control the lifting of the bottom, the rotation of the feeding brush, and the feeding of mulberry leaves by the mulberry leaf feeding tray according to the weighing sensor.

[0006] Further, the upper edge of the side wall of the material receiving frame close to the mulberry leaf feeding tray is lower than the upper edges of the other side walls.

[0007] Further, the side wall of the material receiving frame close to the mulberry leaf feeding tray is arranged to be liftable.

[0008] Further, a winding device is provided on the outer side wall of the material receiving frame. Flexible baffles are respectively provided around the bottom. One end of the flexible baffle is fixedly connected to the bottom, and the other end of the flexible baffle respectively bypasses the upper edge of the corresponding side wall of the material receiving frame upward and is connected to the winding device. The winding device is used to wind the flexible baffle.

[0009] Further, the winding device on the side of the material receiving frame close to the mulberry leaf feeding tray is an elastic winding device, and the elastic winding device can automatically tension the flexible baffle according to the tension at both ends of the corresponding flexible baffle.

[0010] Further, a lifting mechanism is provided on the frame. The lifting mechanism includes a movable pulley and a rope and pulley mechanism. The movable pulley is rotatably arranged on the bottom of the frame. The bottom of the frame is slidably arranged up and down in the material storage frame. The rope and pulley mechanism can drive the movable pulley to move up and down.

[0011] Further, the rope and pulley mechanism includes a fixed pulley, a pulley rope, and a rope and pulley winding and unwinding device. The number of fixed pulleys is at least one more than the number of movable pulleys. The fixed pulley is rotatably arranged at the upper end of the material storage frame. Both ends of the pulley rope bypass one of the movable pulleys and then respectively bypass two of the fixed pulleys, and both ends of the pulley rope are synchronously wound and unwound by the same rope and pulley winding and unwinding device.

[0012] Further, the rope and pulley winding and unwinding device includes a rotation driving device and a drum. Both ends of the pulley rope are wound in the same direction and fixed on the drum.

[0013] Further, an installation frame is further provided at the upper end of the material storage frame. The feeding brush is rotatably arranged on the installation frame. The rotating shaft of the feeding brush is arranged vertically. A plurality of brush heads are provided on the feeding brush. The brush heads are arranged at intervals around the rotating shaft of the feeding brush, and the brush heads are inclined downward along the radial direction of the feeding brush.

[0014] Further, the bottom of the mulberry leaf feeding tray can be opened and closed, and the control unit can control the opening and closing of the bottom of the mulberry leaf feeding tray.

[0015] The beneficial effects of the present invention are as follows:

[0016] When the mulberry leaf adding device is in use, the mulberry leaves to be added are placed in the material storage frame. The control unit controls the feeding brush to rotate to send the mulberry leaves in the material storage frame into the mulberry leaf feeding tray. The weighing sensor detects the weight of the mulberry leaves in the mulberry leaf feeding tray. When the target weight is not reached, the control unit controls the feeding brush to continue rotating to send in mulberry leaves. When the weight increase of the mulberry leaves in the mulberry leaf feeding tray slows down, the control unit controls the bottom of the frame to rise so that the mulberry leaves in the material storage frame are closer to the feeding brush, so as to make the mulberry leaves enter the mulberry leaf feeding tray faster, and the mulberry leaves of the target weight are added to the silkworm tray through the mulberry leaf feeding tray.

[0017] The upper edge of the side wall of the material storage frame close to the mulberry leaf feeding tray is set lower than the upper edges of the other side walls to prevent the mulberry leaves from falling from the other side when being sent into the mulberry leaf feeding tray by the feeding brush, and reduce the loss of mulberry leaves during the feeding process. The side wall of the material storage frame close to the mulberry leaf feeding tray can be lifted and lowered, so that when there are fewer mulberry leaves in the material storage frame, this side wall can be lowered to enable the feeding brush to send the remaining mulberry leaves into the mulberry leaf feeding tray.

[0018] The flexible baffle prevents mulberry leaves from falling through the gap between the inner wall and the bottom of the material storage frame, reducing the loss of mulberry leaves. The winding device stores the flexible baffle to prevent it from interfering with the feeding brush when sending out mulberry leaves. The elastic winding device automatically winds and unwinds the flexible baffle so that the flexible baffle can automatically adapt to the lifting of the side wall of the material storage frame.

[0019] Other advantages, objects and features of the present invention will be set forth in part in the following description, and in part will be obvious to those skilled in the art upon examination of the following, or may be learned from the practice of the present invention. The objects and other advantages of the present invention may be realized and obtained by the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please refer to Figure 1-2 , the present invention provides a technical solution: a mulberry leaf adding device, including a frame 1 and a control unit 2. A mulberry leaf feeding tray 3, a weighing sensor 4 and a material receiving frame 51 with through upper and lower ends are provided on the frame 1. A liftable bottom 52 is provided in the material receiving frame 51. The mulberry leaf feeding tray 3 is arranged on one side of the upper opening of the material receiving frame 51. A feeding brush 61 is provided at the upper opening of the material receiving frame 51. The rotation of the feeding brush 61 can send the mulberry leaves contained in the material receiving frame 51 into the mulberry leaf feeding tray 3. The weighing sensor 4 is used to measure the load-bearing of the mulberry leaf feeding tray 3. The control unit 2 is configured to control the lifting of the bottom 52, the rotation of the feeding brush 61 and the feeding of mulberry leaves by the mulberry leaf feeding tray 3 according to the weighing sensor 4. It can quantitatively add mulberry leaves to the silkworm tray through the mulberry leaf feeding tray 3.

[0030] It can be understood that the actions of lifting the bottom 52, rotating the feeding brush 61 and feeding mulberry leaves by the mulberry leaf feeding tray 3 need to be realized by a certain execution or driving mechanism. The control unit 2 can be configured to control the corresponding execution mechanism or driving mechanism to realize the lifting of the bottom 52, the rotation of the feeding brush 61 and the feeding of mulberry leaves by the mulberry leaf feeding tray 3 through control. The structure of the specific execution mechanism or driving mechanism can be realized according to the disclosure of the present invention, or can also be realized by well-known or commonly used means in the industry.

[0031] In one embodiment, an installation frame 62 is further provided at the upper end of the material storage frame 51. The feeding brush 61 is rotatably arranged on the installation frame 62. The rotating shaft of the feeding brush 61 is arranged vertically, and a plurality of brush heads 611 are provided on the feeding brush 61. The brush heads 611 are arranged at intervals around the rotating shaft of the feeding brush 61, and the brush heads 611 are inclined downward along the radial direction of the feeding brush 61. Specifically, the feeding brush 61 is driven to rotate by a rotating driving device, such as a motor or a hydraulic motor, directly or indirectly driving the feeding brush 61 to rotate. The brush heads 611 can be set in a brush shape or a rod shape, and materials such as plastic or silica gel can be used. It can be understood that the feeding brush 61 can also be set to rotate horizontally, such as using a roller brush structure. The feeding brush 61 can be arranged in multiple, multiple rows or an array to facilitate feeding mulberry leaves into the mulberry leaf feeding tray 3. Different feeding brushes 61 can also be set with different rotation directions to cooperate with each other to transport mulberry leaves. In one embodiment, the installation frame 62 is set in a plate shape or a mesh shape to prevent mulberry leaves from falling off from the upper end opening of the material storage frame 51. The installation frame 62 can be set in a detachable or openable structure to facilitate adding mulberry leaves to the material storage frame 51.

[0032] In one embodiment, the bottom of the mulberry leaf feeding tray 3 is provided in an openable and closable manner, and the control unit 2 can control the opening and closing of the bottom of the mulberry leaf feeding tray 3. Specifically, the mulberry leaf feeding tray 3 is provided with an opening, and a sliding or rotating sealing plate is provided at the opening. The sealing plate can be driven to rotate or slide through a rotating or telescopic mechanism, and the sealing plate rotates or slides to open or block the opening, so as to realize the mulberry leaf feeding tray 3 for storing mulberry leaves or feeding mulberry leaves. Preferably, a baffle is further provided on the side of the mulberry leaf feeding tray 3 away from the material storage frame 51.

[0033] In one embodiment, the upper edge of the side wall of the material storage frame 51 close to the mulberry leaf feeding tray 3 is lower than the upper edges of the other side walls. This is to prevent mulberry leaves from falling from the other sides when being fed into the mulberry leaf feeding tray 3 by the feeding brush 61, and reduce the loss of mulberry leaves during the feeding process. In one embodiment, when there is less mulberry leaves in the material storage frame 51, this side wall can be lowered to facilitate the feeding brush 61 to feed the remaining mulberry leaves into the mulberry leaf feeding tray 3. It can be understood that when this side wall is lowered, the bottom of the frame 52 is appropriately raised at the same time, and the mulberry leaves can be more easily fed into the mulberry leaf feeding tray 3 by the feeding brush 61 after the obstruction of the side wall is reduced.

[0034] In one embodiment, a lifting mechanism 7 is provided on the frame 1. The lifting mechanism 7 includes a movable pulley 71 and a rope and pulley mechanism 72. The movable pulley 71 is rotatably arranged on the bottom frame 52. The bottom frame 52 is slidably arranged up and down in the material storage frame 51, and the rope and pulley mechanism 72 can drive the movable pulley 71 to move up and down. Preferably, the movable pulley 71 is arranged on the bottom surface of the bottom frame 52. In one embodiment, a rotatable guide wheel 521 is further arranged on the bottom surface of the bottom frame 52, and the guide wheel 521 abuts against the inner wall of the material storage frame 51. Under the constraint of the guide wheel 521 and the inner wall of the material storage frame 51, the bottom frame 52 moves up and down more smoothly and is not prone to tipping over. The movable pulley 71 and the rope and pulley mechanism 72 drive the bottom frame 52 to move, occupying less space in the material storage frame 51 below the bottom frame 52 compared with using a conventional hydraulic cylinder or a scissor-type telescopic mechanism. More mulberry leaves can be loaded into the material storage frame 51. In one embodiment, the rope and pulley mechanism 72 includes a fixed pulley 721, a pulley rope 722, and a rope and pulley winding and unwinding device 723. The number of fixed pulleys 721 is at least one more than the number of movable pulleys 71. The fixed pulley 721 is rotatably arranged at the upper end of the material storage frame 51. Both ends of the pulley rope 722 bypass a movable pulley 71 and then respectively bypass two fixed pulleys 721, and both ends of the pulley rope 722 are synchronously wound and unwound by the same rope and pulley winding and unwinding device 723. Specifically, the rope and pulley winding and unwinding device 723 includes a rotation driving device 7231 and a winding drum 7232. Both ends of the pulley rope 722 are wound in the same direction and fixed on the winding drum 7232. The winding drum 7232 rotates under the drive of the rotation driving device 7231, and can wind or release both ends of the pulley rope 722 simultaneously, accelerating the lifting speed of the bottom frame 52.

[0035] In one embodiment, a winding device 54 is provided on the outer side wall of the material storage frame 51. Flexible baffles 53 are respectively arranged around the bottom frame 52. One end of the flexible baffle 53 is fixedly connected to the bottom frame 52, and the other end of the flexible baffle 53 respectively bypasses the upper edge of the corresponding side wall of the material storage frame 51 and is connected to the winding device 54, and the winding device 54 is used for winding the flexible baffle 53. The flexible baffle 53 prevents mulberry leaves from falling through the gap between the inner wall of the material storage frame 51 and the bottom frame 52, reducing mulberry leaf loss. The winding device 54 stores the flexible baffle 53 to prevent the flexible baffle 53 from interfering with the feeding brush 61 to send out mulberry leaves. In one embodiment, the winding device 54 on the side of the material storage frame 51 close to the mulberry leaf feeding tray 3 is an elastic winding device, and the elastic winding device can automatically tension the flexible baffle 53 according to the tension at both ends of the corresponding flexible baffle 53. The elastic winding device automatically winds and unwinds the flexible baffle 53 so that the flexible baffle 53 can automatically adapt to the lifting of the side wall of the material storage frame 51. The winding device 54 can adopt a winding device that drives a reel to wind the flexible baffle 53 by a motor or other rotation driving devices. The elastic winding device is a winding device that drives the reel to rotate by using a coil spring or other elastic structures. The elastic winding device automatically winds and unwinds the flexible baffle 53 so that the flexible baffle 53 can automatically adapt to the lifting of the side wall of the material storage frame 51.

[0036] It can be understood that based on the movement driving mechanism and power source arrangement with the above structure, the specific structure of the control unit 2 can be set through corresponding rotation and telescopic driving structures. The specific structure of the control unit 2 does not belong to the design key points of the present invention and will not be elaborated here. The frame 1 can be set according to the structural cooperation of other components. Preferably, the frame 1 is provided with a traveling mechanism, and the traveling mechanism drives the entire device to move, so as to facilitate the feeding of mulberry leaves into different mulberry leaf trays. Preferably, a weighing sensor 8 is further provided on the frame 1, and the weighing sensor 8 is used to measure the load weight on the material receiving frame 51. The winding device 54 and the wheel rope mechanism 72 are both fixedly arranged on the material receiving frame 51. According to the measured values of the weighing sensor 8 and the weighing sensor 4, the data of the amount of mulberry leaves added each time by the mulberry leaf feeding tray 3 and the data of the mulberry leaves in the material receiving frame 51 can be managed, so as to realize the comprehensive management of mulberry leaf feeding and utilization rate.

[0037] Working principle: When this mulberry leaf adding device is in use, the mulberry leaves to be added are placed in the material receiving frame 51. The control unit 2 controls the rotation of the feeding brush 61 to send the mulberry leaves in the material receiving frame 51 into the mulberry leaf feeding tray 3. The weighing sensor 4 detects the weight of the mulberry leaves in the mulberry leaf feeding tray 3. When the target weight is not reached, the control unit 2 controls the feeding brush 61 to continue rotating to send in mulberry leaves. When the weight increase of the mulberry leaves in the mulberry leaf feeding tray 3 slows down, the control unit 2 controls the bottom 52 of the frame to rise so that the mulberry leaves in the material receiving frame 51 are closer to the feeding brush 61, so as to make the mulberry leaves enter the mulberry leaf feeding tray 3 faster, and the mulberry leaves with the target weight are added to the mulberry leaf tray through the mulberry leaf feeding tray 3.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
