DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] An embodiment of an automatic cleaning device for cleaning silkworm baskets of the present invention is as follows Figures 1 to 10 As shown, it includes a base 100, a cleaning tank 200, a swing frame 600, and a cleaning mechanism 500.

[0021] The cleaning tank 200 is arranged on the base 100, and is used to hold cleaning liquid and the silkworm basket 300, wherein the silkworm basket 300 is a rectangular frame, including four side surfaces of front, back, left and right and a bottom surface, and the bottom surface is placed downward in the cleaning tank 200; the side surfaces and bottom surfaces of the silkworm basket 300 are both hollow surfaces, that is, multiple hollow holes are arranged on the side surfaces and the bottom surface.

[0022] The swing frame 600 is disposed above the inner circle of the silkworm basket 300 and can swing back and forth and left and right in the horizontal direction.

[0023] There are multiple cleaning mechanisms 500 distributed circumferentially around the swing frame 600, and each cleaning mechanism 500 corresponds to a side surface of the silkworm basket 300; specifically, there are four cleaning mechanisms 500.

[0024] The cleaning mechanism 500 includes an articulated frame 700 and a cleaning assembly 900. The articulated frame 700 is mounted on the swing frame 600. The cleaning assembly 900 includes at least two cleaning roller groups 910. The at least two cleaning roller groups 910 are both mounted on the articulated frame 700 to rotate around a vertical axis and are arranged in sequence along the horizontal direction of the side of the corresponding silkworm basket 300. In the initial state, the hinge position of the at least two cleaning roller groups 910 and the articulated frame 700 is located between the at least two cleaning roller groups 910. Each cleaning roller group 910 is vertically arranged and can rotate around its own axis. Each cleaning roller group 910 is provided with a plurality of cleaning airbags 911. The articulated frame 700 has a first state, a second state and a third state when swinging with the swing frame 600. In the first state, the articulated frame 700 allows at least two cleaning roller groups 910 to move away from each other in a vertical state until they respectively abut against the corners of the sides of the silkworm basket 300; in the second state, the articulated frame 700 inflates the cleaning airbag 911; in the third state, the articulated frame 700 enables the cleaning roller group 910 to drive the silkworm basket 300 to swing synchronously with the swing frame 600.

[0025] When the swing frame 600 swings to one side, the cleaning roller set 910 of one of the cleaning mechanisms 500 will contact the side of the silkworm basket 300. At this time, the articulated frame 700 is in the first state. Since in the initial state, the hinged position of at least two cleaning roller sets 910 and the articulated frame 700 is located between at least two cleaning roller sets 910, when the swing frame 600 continues to swing, at least two cleaning roller sets 910 will move away from each other. The cleaning roller set 910 can rotate around its own axis during the movement to clean the side of the silkworm basket 300. When the cleaning roller set 910 moves to the corner of the side of the silkworm basket 300, the articulated frame 700 switches to the second state, and the articulated frame 700 inflates the cleaning airbag 911, and the cleaning airbag 911 inflates and expands and is stuck in the hollow hole of the silkworm basket 300. When the cleaning airbag 911 is inflated to the limit state, the articulated frame 700 switches to the third state, so that the cleaning roller group 910 drives the silkworm basket 300 to swing synchronously with the swing frame 600, lifts the silkworm basket 300 and makes it tilted, and the bottom surface of the silkworm basket 300 can be cleaned under the flushing of the water flow.

[0026] By setting the cleaning roller set 910 to fit the side of the silkworm basket 300, the cleaning airbag 911 on the cleaning roller set 910 can buffer the collision between the cleaning roller set 910 and the silkworm basket 300, and the cleaning airbag 911 can clean the side of the silkworm basket 300 during the movement of the cleaning roller set 910, and can also clean the hollow holes of the silkworm basket 300 during the expansion of the cleaning airbag 911. Further, the silkworm basket 300 is clamped by the expansion of the cleaning airbag 911, so that the cleaning roller set 910 drives the silkworm basket 300 to swing synchronously with the swing frame 600, and rinses the silkworm basket 300. Compared with the rigid clamping method, this flexible clamping method can reduce the damage to the silkworm basket 300, and the swing of the swing frame 600 in the front-back and left-right directions drives the silkworm basket 300 to shake, so as to achieve the cleaning of the side and bottom of the silkworm basket 300.

[0027] In this embodiment, the articulated frame 700 includes an articulated shaft 710, an air cavity shell 730, a mounting frame 740, a connecting frame 750 and a transmission assembly; the articulated shaft 710 and the air cavity shell 730 are both rotatably mounted on the swing frame 600 around a reference axis, and the air cavity shell 730 is located at the lower side of the articulated shaft 710; specifically, the swing frame 600 is provided with a group of first mounting holes 611 and a group of second mounting holes 612 corresponding to each cleaning mechanism 500, and the second mounting holes 612 are parallel to the first mounting holes 611 and are located at the lower side of the first mounting holes 611; the articulated shaft 710 is rotatably mounted on the first mounting hole 611, and rotating shafts 732 are provided on both sides of the air cavity shell 730, and the rotating shafts 732 are rotatably mounted on the second mounting holes 612. A piston assembly 720 is slidably mounted in the air cavity shell 730, one end of the piston assembly 720 extends out of the air cavity shell 730 and is hinged to the hinge shaft 710 around the reference axis; the interior of the air cavity shell 730 is connected to the interior of the cleaning airbag 911. The mounting frame 740 is hinged to the air cavity shell 730 around the reference axis; there are multiple connecting frames 750, each connecting frame 750 is rotatably mounted on the mounting frame 740 around a vertical axis, and each cleaning roller group 910 is rotatably mounted on a connecting frame 750. The transmission assembly is arranged between the connecting frame 750 and the air cavity shell 730, and is used to limit the relative rotation of the air cavity shell 730 and the mounting frame 740 when at least two cleaning roller groups 910 are in a vertical state and move away from each other to respectively abut against the corners of the side of the silkworm basket 300. When the air cavity shell 730 rotates with the swing frame 600 relative to the hinge shaft 710, the piston assembly 720 moves in the air cavity shell 730 and squeezes the gas to the cleaning airbag 911; after the cleaning airbag 911 is inflated to the limit, the air cavity shell 730 and the hinge shaft 710 rotate synchronously with the swing frame 600, and drive the cleaning roller group 910 to swing synchronously through the mounting frame 740 and the connecting frame 750; wherein, the reference axis is the horizontal direction parallel to the side of the silkworm basket 300 corresponding to the hinge frame 700. When the hinge frame 700 is in the first state, the hinge shaft 710, the piston assembly 720 and the air cavity shell 730 swing synchronously with the swing frame 600, the cleaning roller group 910 fits the side of the silkworm basket 300, and the mounting frame 740 rotates around the air cavity shell 730 through the connecting frame 750. When the articulated frame 700 is in the second state, the rotation between the air cavity shell 730 and the mounting frame 740 is restricted, and the cleaning roller group 910 restricts the air cavity shell 730 from rotating with the swing frame 600 through the connecting frame 750 and the mounting frame 740. The air cavity shell 730 rotates relative to the hinge shaft 710, and the piston assembly 720 moves in the air cavity shell 730 to squeeze gas into the cleaning airbag 911. After the cleaning airbag 911 is inflated to the limit, the air cavity shell 730 cannot further rotate relative to the hinge shaft 710, and the articulated frame 700 switches to the third state, swinging with the swing frame 600 synchronously with the hinge shaft 710, and driving the cleaning roller group 910 to swing synchronously through the mounting frame 740 and the connecting frame 750, thereby driving the silkworm basket 300 to swing upward.

[0028] In some other embodiments, in order to prevent the bottom of the silkworm basket 300 from being scratched against the bottom of the cleaning tank 200 , an elastic rope may be used to suspend the silkworm basket 300 in the cleaning tank 200 .

[0029] In this embodiment, connecting shafts 731 along the reference axis are provided on both sides of the air cavity shell 730, and connecting holes 741 for rotationally cooperating with the connecting shaft 731 are provided on the mounting frame 740, and the end surface of the connecting hole 741 is a conical surface; the transmission assembly includes a sliding cylinder 761 and a transmission wheel 762, and the sliding cylinder 761 is spline-matched with the connecting shaft 731, so that the sliding cylinder 761 can move axially relative to the connecting shaft 731 and is restricted from rotating relative to the connecting shaft 731; a conical wheel 763 for cooperating with the conical surface of the connecting hole 741 is provided at the end of the sliding cylinder 761; the sliding cylinder A rack 765 is arranged outside the connecting frame 761 along the axial direction of the connecting shaft 731; the transmission wheel 762 is mounted on the connecting frame 750 and meshes with the rack 765, so that when at least two cleaning roller groups 910 are vertically away from each other, the transmission wheel 762 on the connecting frame 750 meshes with the rack 765, driving the sliding cylinder 761 to move toward the conical surface of the connecting hole 741, until the cleaning roller group 910 abuts against the corner of the side of the silkworm basket 300, and the conical wheel 763 cooperates with the conical surface of the connecting hole 741 to limit the relative rotation of the mounting frame 740 and the air chamber shell 730. Among them, the outer peripheral surface of the conical wheel 763 and the conical surface of the connecting hole 741 are both friction surfaces.

[0030] In this embodiment, the outer sleeve of the sliding cylinder 761 is provided with a collar 764 which moves axially along the connecting shaft 731 synchronously with the sliding cylinder 761 and can rotate relative to the sliding cylinder 761, and the rack 765 is fixed to the collar 764; the end surface of the transmission wheel 762 is provided with a baffle which limits the rack 765 to maintain meshing with the transmission wheel 762. Preferably, the baffle can be provided with a slot along the length direction of the rack 765, and the rack 765 is limited to slide in the slot, thereby ensuring that it is always meshed with the transmission wheel 762.

[0031] In this embodiment, torsion springs (not shown in the figure) are arranged between the connecting frame 750 and the mounting frame 740, between the mounting frame 740 and the air cavity shell 730, between the air cavity shell 730 and the swing frame 600, and between the hinge shaft 710 and the swing frame 600, and the stiffness coefficients of the torsion springs between the components increase successively.

[0032] In this embodiment, the piston assembly 720 includes a piston rod 721 and a piston plate 722. The piston plate 722 is slidably installed in the air cavity shell 730 and divides the interior of the air cavity shell 730 into two upper and lower chambers; the piston rod 721 is located on the upper side of the piston plate 722, one end of which is connected to the piston plate 722, and the other end extends out of the air cavity shell 730 and is hinged to the hinge shaft 710; the chamber located below is connected to the outside world, and the chamber located above is connected to the cleaning air bag 911.

[0033] In this embodiment, each cleaning roller group 910 includes at least two cleaning rollers with hollow interiors. At least two cleaning rollers of the same cleaning roller group 910 are mounted on the same connecting frame 750 via a synchronous frame 920. The cleaning rollers are rotatably mounted on the synchronous frame 920 around a vertical axis. The synchronous frame 920 is hinged to the connecting frame 750 around a vertical axis. The multiple cleaning rollers of the same cleaning assembly 900 are coplanar and parallel to the side of the silkworm basket 300 corresponding to the cleaning assembly 900. The cleaning airbag 911 is disposed on the outer surface of the cleaning roller and communicated with the interior of the cleaning roller. The interior of the cleaning roller is communicated with the upper chamber in the air cavity shell 730 via a hose 930, and the hose 930 is rotatably connected to the cleaning roller.

[0034] In this embodiment, a collecting frame 630 having the same shape as the silkworm basket 300 is provided on the lower side of the swing frame 600, the bottom of the collecting frame 630 is blocked, and a filter plate 620 is provided on each side, and each filter plate 620 corresponds to one of the silkworm basket 300; the upper end of the filter plate 620 is rotatably installed on the collecting frame 630 around a horizontal axis, and the lower end is restricted by the collecting frame 630 to swing toward a side away from the collecting frame 630; when the collecting frame 630 swings with the swing frame 600, the filter plate 620 swings toward the inside of the collecting frame 630 under the resistance of the water flow, and the water flow and impurities enter the collecting frame 630 from the lower side of the filter plate 620. For example, when the collecting frame 630 swings to the left, the lower side of the filter plate 620 on the left swings to the right to open a gap, and water and impurities enter the collecting frame 630 from the gap. When the collecting frame 630 swings to the right, the filter plate 620 on the left abuts against the collecting frame 630 to close the gap, and the water in the collecting frame 630 can be discharged from the filter plate 620, thereby collecting the impurities in the collecting frame 630, reducing the amount of impurities carried when the silkworm basket 300 is taken out upward.

[0035] In this embodiment, a lifting frame 400 is provided on the base 100, and the lifting frame 400 is located above the cleaning tank 200. A transfer block 410 is hinged on the lower side of the lifting frame 400, and the swing frame 600 is hinged on the lower side of the transfer block 410, and the hinge axis of the lifting frame 400 and the transfer block 410 is perpendicular to the hinge axis of the swing frame 600 and the transfer block 410 and is a horizontal axis. The lifting frame 400 is provided with a first motor 430 for driving the transfer block 410 to swing back and forth, and the transfer block 410 is provided with a second motor 440 for driving the swing frame 600 to swing back and forth.

[0036] In this embodiment, a telescopic cylinder 420 for controlling the up and down movement of the lifting frame 400 is provided on the base 100, and the telescopic cylinder 420 or the cleaning tank 200 can be slidably mounted on the base 100. Preferably, the telescopic cylinder 420 is fixed to the base 100, the cleaning tank 200 can be slidably mounted on the base 100, and the lifting frame 400 does not interfere with the sliding of the cleaning tank 200 on the base 100.

[0037] When the automatic cleaning device for cleaning silkworm baskets of the present invention is used, the silkworm basket 300 is placed in a cleaning tank 200 containing cleaning liquid, and the position of the silkworm basket 300 in the cleaning tank 200 is adjusted so that when the swing frame 600 is lowered to the upper part of the silkworm basket 300 along with the lifting frame 400, each cleaning mechanism 500 corresponds to the side of a silkworm basket 300, and the two cleaning roller groups 910 of the same cleaning assembly 900 are symmetrically distributed about the center of the side of the corresponding silkworm basket 300. During cleaning, the first motor 430 and the second motor 440 are alternately started, so that the swing frame 600 alternately swings back and forth and left and right. When the swing frame 600 swings to one side (taking the swing to the left side as an example), the cleaning roller group 910 of the cleaning mechanism 500 located on this side will contact the side of the silkworm basket 300. At this time, the articulated frame 700 is in the first state. Since in the initial state, the hinged position of at least two cleaning roller groups 910 and the articulated frame 700 is located between at least two cleaning roller groups 910, and the stiffness coefficient of the torsion spring between the connecting frame 750 and the mounting frame 740 is the smallest, the swing frame 600 will overcome the torsion between the connecting frame 750 and the mounting frame 740 when it continues to swing, thereby making the two cleaning roller groups 910 move away from each other, and the cleaning rollers of the cleaning roller group 910 can rotate around their own axes during the movement to clean the sides of the silkworm basket 300. At the same time, since the cleaning roller group 910 and the connecting frame 750 are blocked from swinging by the silkworm basket 300, the mounting frame 740 will rotate relative to the air chamber shell 730, and when the two cleaning roller groups 910 move away from each other, the transmission wheel 762 on the connecting frame 750 is engaged with the rack 765 on the sliding cylinder 761, driving the sliding cylinder 761 to move toward the conical surface of the connecting hole 741 on the mounting frame 740, until the cleaning roller group 910 abuts against the corner of the side of the silkworm basket 300, and the conical wheel 763 abuts against the conical surface of the connecting hole 741. The mounting frame 740 and the air cavity shell 730 are matched to limit the relative rotation of the mounting frame 740 and the air cavity shell 730. At this time, the articulated frame 700 switches to the second state; the cleaning roller group 910 limits the air cavity shell 730 to rotate with the swing frame 600 through the connecting frame 750 and the mounting frame 740. The air cavity shell 730 rotates relative to the hinge shaft 710, so that the piston rod 721 drives the piston plate 722 to move upward, and squeezes the gas in the upper chamber of the air cavity shell 730 into the cleaning airbag 911. The cleaning airbag 911 is inflated and stuck in the hollow hole of the silkworm basket 300. When the cleaning airbag 911 is inflated to the limit state, the piston rod 721 cannot further drive the piston plate 722 to move, and the air cavity shell 730 cannot further swing relative to the swing frame 600. At this time, the articulated frame 700 switches to the third state, the air cavity shell 730 and the articulated shaft 710 swing synchronously with the swing frame 600, and drive the cleaning roller group 910 to swing synchronously through the mounting frame 740 and the connecting frame 750, thereby driving the silkworm basket 300 to swing upward, lifting the silkworm basket 300 so that the silkworm basket 300 is tilted, and the bottom and sides of the silkworm basket 300 can be cleaned under the flushing of water.Afterwards, when the swing frame 600 swings in the opposite direction (i.e., to the right), it first drives the silkworm basket 300 back to the initial position, and the cleaning roller set 910 of the cleaning mechanism 500 on the left and the hinge frame 700 are reset under the action of the torsion spring, and the cleaning airbag 911 on the cleaning roller is deflated and separated from the silkworm basket 300. The swing frame 600 swings to the right until the cleaning roller set 910 of the cleaning mechanism 500 on the right contacts the right side of the silkworm basket 300, and the above working process is repeated. When the swing frame 600 switches from front-to-back swinging to left-to-right swinging, or from left-to-right swinging to front-to-back swinging, the switch is performed when it returns to the middle position of the silkworm basket 300.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
