[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0021] According to the prior art, the hopper containing materials needs to be placed in a cleaning machine for cleaning after use, but usually the hopper cover needs to be manually removed before the hopper to be cleaned is sent into the hopper cleaning bin so that the cleaning nozzle can directly enter the hopper for spray cleaning. After cleaning, the hopper cover is manually replaced, resulting in reduced cleaning efficiency of the hopper. In addition, since the hopper containing industrial raw materials is very large and the hopper cover is located at a high height, manual removal and placement of the cover requires a lifting structure or a rack to assist the operation, resulting in the need for complex equipment or structure in the cleaning workshop.

[0022] Based on this, in order to enable the cleaning machine to automatically remove and place the cover of the hopper when cleaning the hopper, the embodiment of the present application provides the following solution.

[0023] Please also read Figures 1 to 4The embodiment of the present application provides a hopper 3 cleaning machine, which includes a base 1, a cleaning chamber 2, a hopper 3, a flushing mechanism, and a cover removal mechanism. The cleaning chamber 2 is arranged on one surface of the base 1, and the hopper 3 is arranged inside the cleaning chamber 2. A feed port 31 is provided at one end of the hopper 3, and an end cover 32 is provided at the end of the hopper 3 where the feed port 31 is provided, and the end cover 32 is used to seal the feed port 31; The cover removal mechanism includes a suction cup 51, a control component and a suction component. The suction cup 51 is arranged on the control component. The control component and the suction component are both arranged on the end of the cleaning bin 2 facing away from the base 1. The suction component is used to provide suction to the suction cup 51 to fix the end cover 32. The control component is used to control the up and down movement and horizontal movement of the suction cup 51 so that the suction cup 51 contacts the end cover 32 and removes the end cover 32 from the feed port 31. The flushing mechanism is used to flush the inner wall of the hopper 3 through the feed port 31 after the suction cup 51 removes the end cover 32 from the feed port 31.

[0024] As can be seen from the above, when the cleaning machine is needed, the hopper 3 is placed at a fixed position inside the cleaning chamber 2, and the feed port 31 of the hopper 3 is vertically facing upwards. Then, the cleaning machine is started, and the suction component continuously extracts the air inside the suction cup 51. The control component controls the suction cup 51 to move horizontally and vertically. After the control mechanism makes the bottom of the suction cup 51 contact the top of the end cover 32, the suction component extracts the air inside the suction cup 51, and the external air pressure presses the end cover 32 onto the suction cup 51. The control mechanism then controls the suction cup 51 to move the end cover 32 from the material. The hopper 3 is removed and moved to a suitable position, and then the flushing mechanism can flush the inner wall of the hopper 3 through the feed port 31. After flushing is completed, the flushing mechanism returns to the initial position, and the control mechanism controls the suction cup 51 to move and put the end cover 32 back on the hopper 3, the suction component stops working, and the suction cup 51 is separated from the end cover 32. The control mechanism then controls the suction cup 51 to return to the initial position, so that the end cover 32 on the hopper 3 can be automatically taken and placed when the hopper 3 is cleaned, which simplifies the work process of the staff and reduces the redundancy of supporting equipment inside the workshop.

[0025] In some embodiments, please refer to Figures 1 to 10 The control component includes a stepper motor 521, an L-shaped transmission rod 522, an electric push cylinder 523 and a fixing part. The stepper motor 521 is fixedly arranged on the side of the cleaning chamber 2 facing away from the base 1. The output shaft of the stepper motor 521 passes through the cleaning chamber 2. The L-shaped transmission rod 522 is arranged inside the cleaning chamber 2. One end of the L-shaped transmission rod 522 is fixedly connected to the output shaft of the stepper motor 521. A mounting sleeve 525 is fixedly arranged on the other end of the L-shaped transmission rod 522. The electric push cylinder 523 is fixedly arranged inside the mounting sleeve 525. The output shaft of the electric push cylinder 523 passes through the mounting sleeve 525. The fixing part is arranged on the mounting shaft of the electric push cylinder 523 and is used to connect the mounting shaft of the electric push cylinder 523 and the suction cup 51. A matching block 321 is provided on the side of the end cover 32 , and a slot 33 matching with the matching block 321 is provided on the hopper 3 .

[0026] With such arrangement, when the control component controls the suction cup 51 to move, the stepper motor 521 drives the L-shaped transmission rod 522 to rotate, and the horizontal side of the L-shaped transmission rod 522 drives the installation sleeve 525, the electric push cylinder 523, the fixing part and the suction cup 51 to rotate around the output shaft of the stepper motor 521. After the suction cup 51 moves to the top of the center position of the end cover 32, the output shaft of the electric push cylinder 523 pushes the suction cup 51 downward until the bottom of the suction cup 51 contacts the top of the end cover 32, and then the suction cup 51 sucks the end cover 32 tightly under the action of the suction component, and the output shaft of the electric push cylinder 523 drives the suction cup 51 and the end cover 32 to move upward and separate from the hopper 3, and then the stepper motor 52 The L-shaped transmission rod 522 is then driven to rotate to move the suction cup 51 to the initial position, thereby removing the end cover 32 from above the hopper 3. After the flushing mechanism completes flushing the inner wall of the hopper 3, the control mechanism controls the suction cup 51 to move and put the end cover 32 back to its original position and then moves the suction cup 51 back to the initial position. When the control mechanism controls the suction cup 51 to put the end cover 32 back on the hopper 3, the end cover 32 may have a certain deviation from its installation position. The suction assembly can put down the end cover 32 when the control mechanism has not completely put the end cover 32 back to its installation position. The end cover 32 will be automatically installed under the action of gravity and the action of the matching block 321 and the card slot 33.

[0027] Optionally, in some embodiments, referring to Figure 2 and Figure 8 The suction assembly includes a vacuum pump 531, which is arranged on a side of the cleaning chamber 2 facing away from the base 1, and an air inlet of the vacuum pump 531 is connected to a connecting port of the suction cup 51 through a telescopic hose.

[0028] With such arrangement, when the suction cup 51 needs to suck the end cover 32, the vacuum pump 531 draws the air inside the suction cup 51 through the telescopic hose, and when the suction cup 51 contacts the end cover 32, negative pressure is generated inside the suction cup 51, thereby sucking air into the end cover 32. When the end cover 32 needs to be lowered, the vacuum pump 531 stops working, and the air in the vacuum pump 531 returns to the inside of the suction cup 51 under the action of negative pressure, thereby separating the suction cup 51 from the end cover 32; the telescopic hose can be extended and retracted when the control mechanism controls the suction cup 51 to move, and can automatically adapt to the distance between the air inlet of the vacuum pump 531 and the connection port of the suction cup 51.

[0029] Optionally, in some embodiments, referring to Figure 2 , Figure 8 and Fig.10The cleaning machine also includes a drying component, which includes a dryer 61 and a drying nozzle 62. The dryer 61 is arranged on the side of the cleaning bin 2 facing away from the base 1. The drying nozzle 62 is fixedly arranged on the fixing member. The drying nozzle 62 is connected to the air outlet of the dryer 61 through a telescopic hose. A first through hole 322 is opened on the end cover 32, and the first through hole 322 is used for the drying nozzle 62 to be inserted into the interior of the cleaning bin 2.

[0030] With such arrangement, when the control component controls the suction cup 51 to move downward and contact the end cover 32, after the suction cup 51 contacts the end cover 32 and sucks the end cover 32 tightly, the drying nozzle 62 passes through the first through hole 322 and is inserted into the hopper 3. After the cleaning mechanism completes the flushing of the inner wall of the hopper 3 and the suction cup 51 puts the end cover 32 back on the hopper 3, the control mechanism keeps the suction cup 51 and the drying nozzle 62 stationary, and the dryer 61 blows dry hot air into the hopper 3 through the telescopic hose and the drying nozzle 62. The hot air passes through the interior of the hopper 3 and contacts the inner wall of the hopper 3, accelerating the evaporation of residual water on the inner wall of the hopper 3, and then the hot air continuously takes away the water vapor and blows it out from the discharge port at the bottom of the hopper 3 to the outside of the hopper 3, so that the inner wall of the hopper 3 can be quickly dried, shortening the time of the cleaning machine for cleaning the hopper 3 and improving the working efficiency of the cleaning machine; after completing the drying of the inner wall of the hopper 3, the control mechanism controls the suction cup 51 and the drying nozzle 62 to move, and the drying nozzle 62 is moved out from the inside of the hopper 3.

[0031] Optionally, in some embodiments, see Figure 6 and Figure 8 The fixing part includes a cross bar 524, the middle part of the cross bar 524 is fixedly connected to the end of the output shaft of the electric push cylinder 523, the suction cup 51 is fixedly connected to one end of the cross bar 524, and the nozzle is fixedly connected to the end of the cross bar 524 away from the suction cup 51.

[0032] In this configuration, the length of the cross bar 524 is consistent with the distance from the center of the first through hole 322 to the center of the end cover 32, and the cross bar 524 can simultaneously drive the suction cup 51 and the drying nozzle 62 to move to complete the above operation.

[0033] Optionally, in some embodiments, see Fig.11 and Fig.12 A blocking mechanism is provided on the end cover 32 , and the blocking mechanism is used to block the first through hole 322 when the drying nozzle 62 is located outside the cleaning chamber 2 .

[0034] With such arrangement, the blocking mechanism can automatically close the first through hole 322 when there is no need to remove the end cover 32, so that the end cover 32 can effectively seal the outlet hopper 3 of the hopper 3. The blocking mechanism can also automatically open when the drying nozzle 62 is inserted into the interior of the hopper 3, thereby facilitating the operation of the drying assembly.

[0035] Optionally, in some embodiments, see Figures 9 to 12 The sealing mechanism includes a pair of semicircular sealing plates 71 and a closing assembly. A hinge rod 323 is fixedly provided on the side of the end cover 32 facing away from the suction cup 51. The edge of the sealing plate 71 is rotatably connected to the hinge rod 323. The sealing mechanism also includes an elastic member, which is used to apply a torsional force to the sealing plate 71 to make it fit with the end cover 32 to close the first through hole 322.

[0036] With this arrangement, when there is no need to remove the end cover 32, the elastic member applies a force to the sealing plate 71 to rotate it around the hinge rod 323, so that the edge of the sealing plate 71 abuts against the portion of the end cover 32 located at the edge of the first through hole 322 to form a seal, and the two semicircular sealing plates 71 cooperate to close the first through hole 322. When the end cover 32 needs to be removed, the control mechanism controls the drying assembly to move downward and contact the straight edges of the two sealing plates 71 away from the hinge rod 323, and then the drying spray The head 62 continues to move downward and pushes the sealing plate 71 to rotate around the hinge rod 323 to open the first through hole 322. After the drying nozzle 62 moves to the lowest point, the two sealing plates 71 can keep the first through hole 322 semi-closed under the action of the elastic member, thereby reducing the hot air leakage from the first through hole 322; after the control mechanism moves the drying nozzle 62 out of the hopper 3, the elastic member causes the two sealing plates 71 to close the first through hole 322 again, thereby ensuring the sealing effect of the end cover 32 on the feed port 31.

[0037] Optionally, in some embodiments, see Fig.11 and Fig.12 The elastic member includes a torsion spring 73 , which is sleeved on the hinge rod 323 , one end of the torsion spring 73 abuts against the end cover 32 , and the other end of the torsion spring 73 abuts against a surface of the blocking plate 71 facing away from the end cover 32 .

[0038] With such arrangement, the end of the torsion spring 73 in contact with the end cover 32 remains stationary, while the end of the torsion spring 73 in contact with the sealing plate 71 can continuously apply force to the sealing plate 71 to rotate it around the hinge rod 323, thereby making the sealing plate 71 automatically close.

[0039] Optionally, in some embodiments, see Figure 2 and Figure 7 The flushing mechanism includes a flushing nozzle 41, an electric telescopic rod 42 and a connecting pipe 43. A second through hole 21 is opened on the side of the cleaning chamber 2 facing away from the base 1. The electric telescopic rod 42 and the connecting pipe 43 are both fixedly arranged on the side of the cleaning chamber 2 facing away from the base 1. The output rod of the electric telescopic rod 42 passes through the second through hole 21. The flushing nozzle 41 is fixedly connected to the output rod of the electric telescopic rod 42. The flushing nozzle 41 is connected to one end of the connecting pipe 43 through a telescopic hose. The other end of the connecting pipe 43 is used to connect to an external water source.

[0040] With such arrangement, when installing the cleaning machine, the end of the connecting pipe 43 away from the telescopic hose can be connected to an external water source. After the control component controls the suction cup 51 to remove the end cover 32, the output rod of the electric telescopic rod 42 drives the flushing nozzle 41 to move downward and pass through the feed port 31 into the hopper 3. At the same time, the flushing nozzle 41 pulls the telescopic hose to extend, and the external water source sprays water toward the inner wall of the hopper 3 through the telescopic hose and the flushing nozzle 41 to flush the inner wall of the hopper 3. The flushed water then flows out of the hopper 3 through the feed port 31 at the bottom of the hopper 3. After flushing is completed, the electric telescopic rod 42 drives the flushing nozzle 41 to move back to its original position, and the telescopic hose contracts to complete the flushing of the inner wall of the hopper 3.

[0041] Optionally, in some embodiments, see Figure 1 , Figure 4 and Fig.13 The cleaning machine further comprises a bracket and a rotating assembly, wherein the bracket is used to install and support the hopper 3 and allow the hopper 3 to rotate, and the rotating assembly comprises a motor 9, which is arranged on a side of the base 1 facing away from the cleaning bin 2, and the output shaft of the motor 9 passes through the base 1 and is rotatably connected to the bottom of the hopper 3 through a gear set; The bracket includes an upper support ring 81, a lower support ring 82, a plurality of connecting rods 83 and a plurality of legs 84, one end of the leg 84 is fixedly connected to the lower support ring 82, and the upper support ring 81 is fixedly connected to the lower support ring 82 through the connecting rod 83; the hopper 3 is inserted into the upper support ring 81 and the lower support ring 82, and a plurality of rollers 811 are rotatably connected to the inner circumference of the upper support ring 81 and the inner circumference of the lower support ring 82, the outer circumference of the hopper 3 abuts against the rollers 811, and the outer circumference of the hopper 3 and the outer circumference of the upper support ring 81 are provided with calibration lines 34; A pair of pulley grooves 11 are symmetrically arranged on the base 1. A slider 841 is fixedly arranged on one end of the leg 84 away from the lower support ring 82. A plurality of pulleys 12 are rotatably arranged inside the pulley groove 11. The slider 841 is slidably connected inside the pulley groove 11 and abuts against the pulley 12.

[0042] With such arrangement, when installing the hopper 3, the bracket is pushed out from the inside of the cleaning bin 2, and the slider 841 slides on the top of the pulley 12. After the bracket is moved out, the hopper 3 is placed inside the bracket by using a machine with the discharge port of the hopper 3 facing upwards. The outer peripheral surface of the hopper 3 abuts against each roller 811 to allow the hopper 3 to rotate. Then the bracket and the hopper 3 are pushed back into the cleaning bin 2, and the gear at the bottom of the hopper 3 automatically cooperates with the gear on the output shaft of the motor 9; then the motor 9 is turned on to make the hopper 3 rotate slowly, and the calibration line 34 on the outer wall of the hopper 3 is aligned with the calibration line 34 on the upper support ring 81, so that the end cover 32 on the top of the hopper 3 can be located in the standard position, thereby facilitating the suction cup 51 to suck the end cover 32 and the drying nozzle 62 to pass through the first through hole 322 Insert it into the hopper 3; when flushing the hopper 3, the motor 9 drives the hopper 3 to rotate, and the electric telescopic rod 42 can drive the flushing nozzle 41 to move up and down when spraying water, so that various parts of the inner wall of the hopper 3 can be flushed, thereby improving the cleaning effect of the cleaning mechanism on the hopper 3; after cleaning is completed, the motor 9 controls the calibration line 34 on the hopper 3 to align with the calibration line 34 on the upper support ring 81, and when the subsequent suction cup 51 places the end cover 32 on the hopper 3, the error between the end cover 32 and its installation position is reduced, so that the end cover 32 can be smoothly installed back to its original position with the cooperation of the matching block 321 and the card slot 33; after completing the cleaning of the hopper 3, the bracket and the hopper 3 are pushed out of the cleaning bin and the hopper 3 is removed, and then the bracket is pushed back into the cleaning bin.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
