Description

Technical Field

[0001] This invention belongs to the field of mechanical parts cleaning technology, and in particular relates to a hopper cover cleaning trolley. Background Technology

[0002] Many large pieces of equipment, such as feeders and mixers, are equipped with hopper covers. The hopper cover is a sealing component that works with the hopper. The hopper cover usually has a complex sealing structure and is characterized by its large size and various shapes.

[0003] Previously, when cleaning hopper covers, if they were placed in an automatic cleaning machine, the bottom of the hopper cover and the contact surface with the automatic cleaning machine could not be cleaned properly. If multiple hopper covers were cleaned at the same time, they would accumulate at the bottom of the automatic cleaning machine and would be even more difficult to clean. Therefore, traditional hopper covers required manual cleaning, which was inconvenient and had high labor costs. Summary of the Invention

[0004] The purpose of this invention is to provide a hopper cover cleaning trolley. By starting the motor, the first cam and the second cam can be rotated. The first cam, in conjunction with the spring, can drive the lifting plate to move up and down. The cleaning frame can be driven to swing back and forth through the connecting frame, increasing the contact area between the hopper cover and the cleaning water and improving the cleaning quality. The rotation of the second cam, in conjunction with the spring, can drive the lifting plate to move up and down quickly to create a shaking motion, which can quickly clean water stains on the hopper cover, thus solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A hopper cover cleaning trolley, comprising:

[0007] The base has several wheels at its bottom and columns at the four corners of its top. Two sets of washing racks are rotatably connected between two adjacent columns for placing hopper covers. Handrails are fixedly connected to one side of each column.

[0008] The cleaning frame includes a mounting beam, an upper connecting frame, a lower connecting frame, and multiple connecting uprights. The two ends of the mounting beam are rotatably connected to two adjacent uprights. The upper connecting frame is mounted on the mounting beam, and an inlet for inserting the hopper cover is formed between the upper connecting frame and the mounting beam. The lower connecting frame is connected to the lower part of the upper connecting frame through multiple connecting uprights to support the hopper cover, and the gap in the outline of the lower connecting frame forms an outlet for draining water.

[0009] The transmission mechanism, located at the top of the base, drives multiple cleaning racks to swing back and forth to increase the cleaning area, and can also drive multiple cleaning racks to shake off water droplets.

[0010] Optionally, the transmission mechanism includes two guide rods fixedly connected to the top of the base. The outer walls of the two guide rods are slidably fitted with the same lifting plate. Connecting rods are fixedly connected to the top four corners of the lifting plate. Support rods are fixedly connected to one side of a plurality of adjacent lower connecting frames. Sliding blocks are slidably fitted to the outer walls of the support rods. The same connecting frame is rotatably connected between two adjacent sliding blocks. The connecting frame is fixedly fitted on the corresponding connecting rod. By pushing the lifting plate, the connecting frame can be rotated, which facilitates the adjustment of the tilt angle of the connecting frame.

[0011] Optionally, both sides of the lifting plate are provided with fixed frames, which are fixedly connected to the top of the base. The two fixed frames are rotatably connected through the same rotating shaft. The outer wall of the rotating shaft is fixedly fitted with two second cams that abut against the lifting plate. One side of one of the fixed frames is fixedly connected to the same motor. The output end of the motor is fixedly connected to the rotating shaft. Starting the motor can drive the second cam to rotate, which can cause the lifting plate to vibrate, thereby causing the connecting frame to vibrate.

[0012] Optionally, a spring is fitted on the outer wall of the guide rod, and the two ends of the spring are fixedly connected to the outer wall of the guide rod and the top of the lifting plate, respectively, so as to facilitate the resetting of the lifting plate and its contact with the cam.

[0013] Optionally, the outer wall of the rotating shaft is fitted with two first cams, and the outer wall of the rotating shaft is fitted with two first electromagnet rings. The first electromagnet rings are fixedly connected to one side of the first cams. The outer wall of the rotating shaft is slidably fitted with a second electromagnet ring that cooperates with the first electromagnet rings. The outer wall of the rotating shaft is fixedly fitted with two limiting rings, and the outer wall of the rotating shaft is fitted with two tension springs. The two ends of the tension springs are respectively fixedly connected to the adjacent sides of the limiting rings and the second electromagnet rings, so that the rotating shaft can drive the first cams to rotate, which can drive the lifting plate to rise and fall, and drive the connecting frame to swing.

[0014] Optionally, the mounting beam, upper connecting frame, lower connecting frame, and connecting upright are all cylindrical, and the joints are all rounded. The cylindrical and rounded design prevents water from remaining on the cleaning rack and further improves the drainage effect of the cleaning rack.

[0015] Optionally, the wheels include two directional wheels and two omnidirectional wheels. The two omnidirectional wheels are located below the base on one side of the handle. Placing the omnidirectional wheels below one side of the handle makes it easier to adjust the direction of the cleaning cart and to operate the rotation angle of the cleaning cart more effortlessly.

[0016] Optionally, the base is also provided with a buffer device, which includes a mounting block, an adjusting block, and a buffer block. The mounting block is located on the top of the base. One side of the mounting block is threaded with multiple adjusting bolts. One side of the adjusting block has a waist-shaped hole corresponding to the adjusting bolts. The adjusting block is connected to the mounting block through the adjusting bolts. One end of the adjusting block extends to the outside of the base and is fixedly connected to the buffer block. The buffer block is made of elastic silicone. The buffer device can prevent the hopper cover inside the cleaning cart from colliding with the inner wall of the automatic cleaning machine when the cleaning cart is pushed into the automatic cleaning machine.

[0017] The embodiments of the present invention have the following beneficial effects:

[0018] The motor can be started to drive the first and second cams to rotate. The first cam, in conjunction with the spring, can drive the lifting plate to rise and fall. It can also drive the cleaning frame to swing back and forth through the connecting frame, increasing the contact area between the hopper cover and the cleaning water and improving the cleaning quality. The rotation of the second cam, in conjunction with the spring, can drive the lifting plate to move up and down quickly to create a shaking motion, which can quickly clean the water stains on the hopper cover.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0031] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] Example 1

[0033] Please see Figure 1 and Figure 2 As shown, this embodiment provides a hopper cover cleaning trolley, including:

[0034] The base 1 has several wheels 14 at its bottom and four columns 2 at the top corners of the base 1. Two sets of cleaning racks 3 are rotatably connected between two adjacent columns 2, and a handrail 30 is fixedly connected to one side of each column 2.

[0035] The cleaning frame 3 includes a mounting beam 4, an upper connecting frame 5, a lower connecting frame 6, and multiple connecting rods 7. The two ends of the mounting beam 4 are rotatably connected to two adjacent columns 2 respectively. The upper connecting frame 5 is located on the mounting beam 4, and an inlet for inserting the hopper cover is formed between the upper connecting frame 5 and the mounting beam 4. The lower connecting frame 6 is connected to the lower part of the upper connecting frame 5 through multiple connecting rods 7 to support the hopper cover, and the gap in the outline of the lower connecting frame 6 forms an outlet for draining water.

[0036] The transmission mechanism is located on the top of the base 1 and is used to drive multiple cleaning racks 3 to swing back and forth to increase the cleaning area. At the same time, it can drive multiple cleaning racks 3 to shake off water droplets. In the above technical solution, the transmission mechanism can drive the cleaning racks 3 to swing and vibrate, which facilitates increasing the contact area between the hopper cover and water, and facilitates the treatment of water stains on the hopper cover.

[0037] In one aspect of this embodiment, such as Figure 1 and Figure 4 As shown, the transmission mechanism includes two guide rods 16 fixedly connected to the top of the base 1. The outer walls of the two guide rods 16 are slidably fitted with the same lifting plate 18. Connecting rods 19 are fixedly connected to the four corners of the top of the lifting plate 18. Support rods 8 are fixedly connected to one side of multiple lower connecting frames 6 that are close to each other. Sliding blocks 20 are slidably fitted to the outer walls of the support rods 8. The same connecting frame 21 is rotatably connected between two adjacent sliding blocks 20. The connecting frame 21 is fixedly fitted on the corresponding connecting rods 19. In the above technical solution, pushing the lifting plate 18 upward can drive the connecting rods 19 to move upward. The upward movement of the connecting rods 19 can drive the connecting frame 21 to move. The connecting frame 21 can drive the washing frame 3 to flip through the sliding blocks 20, adjusting the angle of the washing frame 3. At the same time, the sliding blocks 20 slide on the support rods 8 to increase the contact area between the hopper cover and the water.

[0038] In one aspect of this embodiment, such as Figures 3-5 As shown, both sides of the lifting plate 18 are provided with fixed frames 15, which are fixedly connected to the top of the base 1. The two fixed frames 15 are rotatably connected through the same rotating shaft 22. The outer wall of the rotating shaft 22 is fixedly fitted with two second cams 25 that abut against the lifting plate 18. One side of one of the fixed frames 15 is fixedly connected to the same motor 23. The output end of the motor 23 is fixedly connected to the rotating shaft 22. In the above technical solution, starting the motor 23 can drive the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 can drive the second cam 25 to rotate. The rotation of the second cam 25 can drive the lifting plate 18 to move upward. When the protrusion of the second cam 25 moves away from the lifting plate 18, the lifting plate 18 abuts against the second cam 25 under the action of gravity, so that it can reciprocate up and down, driving the washing rack 3 to reciprocate and rotate, forming vibration, which can shake off the water droplets on the hopper cover.

[0039] In one aspect of this embodiment, such as Figures 3-5 As shown, a spring 17 is sleeved on the outer wall of the guide rod 16. The two ends of the spring 17 are fixedly connected to the outer wall of the guide rod 16 and the top of the lifting plate 18, respectively. In the above technical solution, the setting of the spring 17 can make the lifting plate 18 always in contact with the second cam 25, which facilitates the washing frame 3 to rotate back and forth.

[0040] In one aspect of this embodiment, such as Figure 5 and Figure 7 As shown, the outer wall of the rotating shaft 22 is fitted with two first cams 24, and the outer wall of the rotating shaft 22 is fitted with two first electromagnet rings 26. The first electromagnet rings 26 are fixedly connected to one side of the first cams 24. The outer wall of the rotating shaft 22 is slidably fitted with a second electromagnet ring 27 that cooperates with the first electromagnet rings 26. The outer wall of the rotating shaft 22 is fixedly fitted with two limiting rings 28, and the outer wall of the rotating shaft 22 is fitted with two tension springs 29. The two ends of the tension springs 29 are fixedly connected to the limiting rings 28 and the adjacent sides of the second electromagnet rings 27, respectively. In the above technical solution, by activating the second electromagnet rings 27 and the first electromagnet rings 26, the second electromagnet rings 27 and the first electromagnet rings 26 can become one. When the rotating shaft 22 rotates, it can drive the first cams 24 to rotate, thereby driving the lifting plate 18 to rise and fall. This can increase the travel of the lifting plate 18, which is conducive to increasing the swing amplitude of the cleaning frame 3, so as to facilitate the cleaning of the hopper cover.

[0041] In one aspect of this embodiment, such as Figure 2 and Figure 3 As shown, the mounting beam 4, upper connecting frame 5, lower connecting frame 6 and connecting pole 7 are all cylinders, and the joints are all rounded. The cylindrical and rounded design prevents water from remaining on the cleaning rack 3, further improving the drainage effect of the cleaning rack 3.

[0042] Example 2

[0043] Improvements based on Example 1: such as... Figure 1 and Figure 6 As shown, the base 1 is also equipped with a buffer device, which includes a mounting block 9, an adjusting block 10 and a buffer block 11. The mounting block 9 is located on the top of the base 1. Multiple adjusting bolts 12 are threadedly connected to one side of the mounting block 9. The adjusting block 10 has a waist-shaped hole 13 corresponding to the adjusting bolt 12 on one side. The adjusting block 10 is connected to the mounting block 9 through the adjusting bolt 12. One end of the adjusting block 10 extends to the outside of the base 1 and is fixedly connected to the buffer block 11. The buffer block 11 is made of elastic silicone material. The buffer device can prevent the hopper cover inside the cleaning cart from colliding with the inner wall of the automatic cleaning machine when the cleaning cart is pushed into the automatic cleaning machine.

[0044] Example 3

[0045] Improvements based on Example 1: such as... Figure 1 As shown, the wheel 14 includes two directional wheels and two omnidirectional wheels. The two omnidirectional wheels are located below the base 1 on one side of the handle 30. Placing the omnidirectional wheels below one side of the handle 30 makes it easy to adjust the direction of the cleaning cart and makes it easier to control the rotation angle of the cleaning cart.

[0046] The technical solution of this invention is used as follows: When in use, the device is powered on, the hopper cover is placed into the cleaning rack 3, and then the handle 30 is pushed to move the base 1, pushing the base 1 into the cleaning machine until the buffer block 11 contacts the cleaning machine. The cleaning machine is then started for cleaning. Simultaneously, the motor 23, the first electromagnet ring 26, and the second electromagnet ring 27 are started. When the first electromagnet ring 26 moves the second electromagnet ring 27, the first electromagnet ring 26 and the second electromagnet ring 27 become one unit. The motor 23 can drive the rotating shaft 22 to rotate, which in turn drives the second electromagnet ring 27 to rotate. The second electromagnet ring 27 can drive the first cam 24 to rotate through the first electromagnet ring 26. The rotation of the first cam 24 can drive the lifting plate 18 to move upward, which in turn drives the connecting rod 19 to move upward. The connecting rod 19 can drive the connecting frame 21 to move upward. The connecting frame 21 moves upward through sliding... Block 20 can drive the cleaning frame 3 to rotate significantly, and can also drive the cleaning frame 3 to swing back and forth, increasing the cleaning angle and improving the cleaning effect. After cleaning, the second electromagnet ring 27 and the first electromagnet ring 26 are closed. Under the force of the tension spring 29, the second electromagnet ring 27 moves away from the first electromagnet ring 26. At this time, the rotating shaft 22 rotates, which can drive the second cam 25 to rotate. The rotation of the second cam 25 can drive the lifting plate 18 to move upward. The upward movement of the lifting plate 18 can drive the connecting rod 19 to move upward. The connecting rod 19 can drive the connecting frame 21 to move upward. The connecting frame 21 can drive the cleaning frame 3 to rotate slightly through the sliding block 20. When the protrusion of the second cam 25 moves away from the lifting plate 18, the lifting plate 18 quickly returns to its original position under the action of the spring 17, abutting against the protrusion of the second cam 25. This causes the lifting plate 18 to shake rapidly, which can shake off the water droplets on the cleaning frame 3 and the hopper cover, and can quickly clean up water stains.
