Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machines, in particular to a fork mechanism and a cleaning machine. Background Art

[0002] The commonly used cleaning machines on the market currently use a separate spraying method to break up and clean the materials, but this breaking up and cleaning method has certain limitations. It is impossible to clean the materials that stick to each other (such as kelp, seaweed, etc.). After the above materials are broken up and cleaned by the cleaning machine, they still need to be manually placed in a large pool to break up the materials again, and then stirred and cleaned again, which not only increases the labor intensity of people, but also increases the cleaning time and labor costs. Therefore, a fork mechanism and a cleaning machine are urgently needed to solve the above problems. Utility Model Content

[0003] In order to solve the technical problem that the spraying mode of the existing cleaning machine has certain limitations and cannot clean the materials that are stuck to each other, the utility model provides a fork mechanism and a cleaning machine, which can realize the automatic breaking up of materials that are stuck to each other (such as kelp, seaweed, etc.), effectively improve the cleaning effect and cleaning efficiency of materials that are stuck to each other, fundamentally reduce the labor intensity, and reduce the cleaning time and labor cost of the cleaning machine.

[0004] The utility model provides a shift fork mechanism, comprising a shift fork rotating shaft, a shift fork mounting plate and a shift fork, wherein the shift fork rotating shaft is rotatably arranged on a frame of a cleaning machine, one end of the shift fork mounting plate is fixedly connected to the shift fork rotating shaft, and the other end is rotatably connected to the shift fork.

[0005] Furthermore, a mounting sleeve is provided on the upper part of the shift fork mounting plate, and the mounting sleeve is sleeved on the shift fork rotating shaft. The shift fork mounting plate is fixed on the shift fork rotating shaft through the mounting sleeve thereon.

[0006] Furthermore, the shift fork comprises a crossbar and a plurality of vertical bars arranged at equal intervals on one side of the crossbar. The plurality of vertical bars of the shift fork are in direct contact with the material and break up the material in the cleaning liquid water of the cleaning tank.

[0007] Furthermore, the fork mechanism also includes a fork plate symmetrically arranged on both sides of the lower part of the fork mounting plate, the upper end of the fork plate is rotatably connected to the fork mounting plate, and the lower end passes through the cross bar of the fork, and a limiting groove is opened at the lower end of the fork mounting plate, and the cross bar of the fork is located in the limiting groove.

[0008] Furthermore, the fork plate is Z-shaped, and the limiting slot is C-shaped.

[0009] Compared with the prior art, the utility model has the following technical effects:

[0010] During the flushing operation, the fork drives the fork plate to rotate relative to the fork mounting plate under the action of its own weight, but at this time, the limit slots of the fork mounting plate support and limit the crossbar of the fork, thereby limiting the large-angle rotation of the fork plate of the fork, so that the fork and the fork plate remain tilted. The vertical rod of the tilted fork is in direct contact with the material, breaking up the material in the cleaning tank of the cleaning machine, and driving the material to continue to move to the left, effectively improving the cleaning effect and cleaning efficiency of the materials that stick to each other.

[0011] The utility model also provides a cleaning machine, comprising the fork mechanism as described above, a driving motor and a transmission mechanism rotatably connected to the fork mechanism, which is arranged on a frame, wherein the transmission mechanism comprises a rocker arm and a connecting rod, wherein one end of the rocker arm is fixedly connected to the output shaft of the driving motor, and the other end is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to the fork mechanism through a connecting plate. When the driving motor is started, the rocker arm is driven to rotate counterclockwise, thereby driving the connecting rod to move to the right or left; since the connecting rod is fixedly connected to the fork mechanism, the fork mechanism is swung left and right to clean the material.

[0012] Furthermore, the fork mechanism is arranged in plurality along the longitudinal direction of the cleaning tank of the cleaning machine, two adjacent fork mechanisms are connected in series through a synchronization rod, and one of the fork mechanisms is fixedly connected to the output shaft of the driving motor through a rocker arm and a connecting rod. When the driving motor is started, the plurality of synchronization rods are driven, and finally the plurality of fork mechanisms are operated synchronously.

[0013] Furthermore, a second sleeve is provided at one end of the connecting rod, and a first sleeve is provided at both ends of each of the synchronization rods. The connecting rod, the connecting plate and the synchronization rod are fixedly connected by a first pin shaft passing through the second sleeve and the first sleeve.

[0014] Furthermore, a connecting sleeve is provided at the lower part of the connecting plate, and the connecting sleeve is sleeved on the shift fork rotating shaft. The connecting plate is fixed on the shift fork rotating shaft through the connecting sleeve.

[0015] Furthermore, a rocker arm sleeve is provided at one end of the rocker arm, and the rocker arm sleeve is fixedly connected to the output shaft of the driving motor; the rocker arm and the connecting rod are rotatably connected by a second pin shaft penetrating through the other end of the rocker arm.

[0016] Compared with the prior art, the utility model has the following technical effects:

[0017] During the flushing operation, the driving motor starts and drives the rocker arm to rotate counterclockwise. When the rocker arm rotates to the right half circle, the connecting rod is driven to move to the right. Since the fork shaft is rotated and set on the frame of the cleaning machine, the connecting rod drives the fork shaft to rotate clockwise, thereby driving the fork mounting plate to swing to the left (consistent with the direction of material movement). The fork tilts to the left and penetrates into the water. The vertical rod of the fork contacts the material to break up the bonded material in the water. Due to the impact of the water flow on the fork, in order to prevent the fork from being parallel to the water surface after rotation, the fork mounting plate is provided with a limit slot to support and limit the cross rod of the fork, thereby limiting the large-angle inclination of the fork, thereby making the vertical rod of the fork contact the material to break up the bonded material. When the rocker arm rotates to the left half circle, the connecting rod is driven to move to the left, and the connecting rod drives the fork shaft to rotate counterclockwise, which in turn drives the fork mounting plate to swing to the right (opposite to the direction of material movement). However, due to the reverse thrust of the water flow, the fork will remain in a vertical state, and the fork will penetrate into the water under its own weight. The vertical rod of the fork will contact the material and the fork will not bring the material back. The left and right swing of the fork can break up the material and effectively improve the cleaning effect and efficiency of the materials that stick to each other. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Embodiment 1, as Figures 1-2 As shown, a fork mechanism includes a fork shaft 11, a fork mounting plate 12 and a fork 13. The fork shaft 11 is rotatably mounted on the frame 4 of the cleaning machine. One end of the fork mounting plate 12 is fixedly connected to the fork shaft 11, and the other end is rotatably connected to the fork 13. Both ends of the fork shaft 11 are rotatably connected to the bearing seat 11, and the fork shaft 11 is rotated by the bearing seat 111. Each of the bearing seats 111 is fixedly mounted on the vertical plate 6, and each of the vertical plates 6 is mounted on the frame 4 (the portion of the frame 4 supporting the vertical plate 6 is not shown).

[0029] During the flushing operation, the materials (seaweed, kelp, etc.) in the cleaning tank of the cleaning machine move from right to left, the fork shaft 11 rotates clockwise, driving the fork mounting plate 12 to swing to the left, and the fork 13 rotates under the action of its own weight. When the fork 13 is in an inclined state, the fork 13 is located at the far left, and the vertical rod of the inclined fork 13 can directly contact the materials and break up the materials in the cleaning liquid (such as water) in the cleaning tank, and also drive the materials to continue to move to the left.

[0030] As an implementation method, a mounting sleeve 121 is provided on the upper portion of the shift fork mounting plate 12, and the mounting sleeve 121 is sleeved on the shift fork rotating shaft 11. The shift fork mounting plate 12 is fixed on the shift fork rotating shaft 12 by the mounting sleeve 121 thereon.

[0031] As an implementation method, the fork 13 includes a crossbar and a plurality of vertical rods arranged at equal intervals on one side of the crossbar. The fork 13 of this embodiment can be integrally formed. The plurality of vertical rods of the fork 13 directly contact the material and break up the material in the cleaning liquid water of the cleaning tank.

[0032] As an implementable embodiment, the fork mechanism also includes a fork plate 131 symmetrically arranged on both sides of the lower part of the fork mounting plate 12, wherein the fork plate 131 is Z-shaped, the upper end of the fork plate 131 is rotatably connected to the fork mounting plate 12, and the lower end passes through the cross bar of the fork 13. It is worth noting that the fork mounting plate 12 and the cross bar are fixedly connected, and a limiting groove 122 is provided at the lower end of the fork mounting plate 12, wherein the limiting groove 122 is C-shaped, and the cross bar of the fork 13 is located in the limiting groove 122.

[0033] During the flushing operation, the materials (seaweed, kelp, etc.) in the cleaning pool of the cleaning machine are moved from right to left, the fork shaft 11 rotates clockwise, and the fork 13 drives the fork plate 131 to swing to the left relative to the fork mounting plate 12 under the action of its own weight (consistent with the direction of material movement). The fork 13 tilts to the left and penetrates into the water, and the vertical rod of the fork 13 contacts the materials to break up the materials stuck in the water; due to the impact of the water flow on the fork 13, in order to prevent the fork 13 from being parallel to the water surface after rotation, the fork mounting plate 12 is provided with a limiting groove 122 to support and limit the crossbar of the fork 13, thereby limiting the large-angle inclination of the fork 13, and then making the vertical rod of the fork 13 contact with the materials to break up the stuck materials, and also driving the materials to continue to move to the left.

[0034] As an implementation method, each of the fork mounting plate 12 and the two fork plates 131 on both sides thereof are provided with fixing holes and three fixing holes are provided with rotating pins, each of the limiting slots 122 is located below the rotating pin, and each of the forks 24 can rotate around the rotating pin. Specifically, the two fork plates 131 on the fork 24 and the fork mounting plate 12 are rotatably connected via the rotating pin. When the fork 24 drives the fork plate 131 to rotate relative to the fork mounting plate 12 under the action of its own weight, it is actually the fork plate 131 that rotates relative to the rotating pin.

[0035] Embodiment 2, as Figures 3 to 5 As shown, a cleaning machine comprises a fork mechanism 1 as described in any one of the above items, a drive motor 3 and a transmission mechanism 2 rotatably connected to the fork mechanism 1, which is arranged on a frame 4 of the cleaning machine, wherein the transmission mechanism 2 comprises a rocker arm 21 and a connecting rod 22, wherein one end of the rocker arm 21 is fixedly connected to the output shaft of the drive motor 3, and the other end is fixedly connected to one end of the connecting rod 22, and the other end of the connecting rod 22 is fixedly connected to the fork mechanism 1 via a connecting plate 23.

[0036] During the movement of the cleaning machine of this embodiment, the driving motor 3 is started, driving the rocker arm 21 to rotate counterclockwise, thereby driving the connecting rod 22 to move rightward or leftward; since the connecting rod 22 is fixedly connected to the fork mechanism 1, the fork mechanism 1 can swing left and right to clean the material.

[0037] The cleaning machine of this embodiment replaces manual cleaning and can automatically break up mutually adhering materials (such as kelp, seaweed, etc.), effectively improving the cleaning effect and cleaning efficiency of mutually adhering materials, fundamentally reducing the labor intensity, reducing the cleaning time and labor cost of the cleaning machine. It can also effectively prevent the fork 24 from bringing materials back during the swinging process, avoiding repeated cleaning of materials.

[0038] As an implementable embodiment, a plurality of the fork mechanisms 1 are arranged along the longitudinal direction of the cleaning tank of the cleaning machine, and two adjacent fork mechanisms 1 are connected in series through a synchronization rod 24, and one of the fork mechanisms 1 is fixedly connected to the output shaft of the drive motor 3 through a rocker arm 21 and a connecting rod 22. This embodiment does not limit the number of synchronization rods 4 and fork mechanisms 2. When the drive motor 3 is started, the plurality of synchronization rods 24 are driven, and finally the plurality of fork mechanisms 1 are operated synchronously.

[0039] As an implementation method, a second sleeve 221 is provided at one end of the connecting rod 22, and a first sleeve 241 is provided at both ends of each of the synchronous rods 24. The upper parts of the two adjacent connecting plates 23 are respectively provided with first pins 231 on the two first sleeves 241 on the synchronous rod 24, and one of the first pins 231 provided on the connecting plate 23 and the first sleeve 241 also passes through one of the second sleeves 221 and fixes the connecting rod 22, the connecting plate 23 and the synchronous rod 24. The driving motor 3 is started, driving the rocker arm 21 to rotate, thereby driving the connecting rod 22 to rotate; since the fork shaft 22 is rotatably arranged on the frame 4 of the cleaning machine, after the connecting rod 22 rotates, it can drive the connecting plate 23 and the fork mounting plate 12 to rotate, thereby finally driving the fork 13 to rotate.

[0040] As an implementation method, a connecting sleeve 232 is provided at the lower part of the connecting plate 23, and the connecting sleeve 232 is sleeved on the shift fork rotating shaft 11. The connecting plate 23 is fixed on the shift fork rotating shaft 11 through the connecting sleeve 232.

[0041] As an implementable embodiment, a rocker sleeve 211 is provided at one end of the rocker arm 21, and the rocker sleeve 211 is fixedly connected to the output shaft of the drive motor 3; the rocker arm 21 and the connecting rod 22 are rotatably connected by a second pin shaft 212 penetrated on the other end of the rocker arm 21. The rocker arm 21 is fixedly connected to the output shaft of the drive motor 3 through the rocker sleeve 311, and the drive motor 3 is started to drive the rocker sleeve 11 and the rocker arm 21 to rotate. The rocker arm 21 is rotatably connected to the second sleeve 221 at the other end of the connecting rod 3 through the second pin shaft 212. After the rocker arm 21 rotates, the connecting rod 22 is driven to rotate. The first pin shaft 231 is penetrated on the second sleeve 221 at one end of the connecting plate 22, the upper end of the connecting plate 23 and the first sleeve 241. After the connecting rod 22 rotates, the connecting plate 23, the shift fork rotating shaft 11, the shift fork mounting plate 12, and the shift fork 13 are driven to rotate. As an implementation method, the fork device further includes a motor shield 5, which is disposed on the drive motor 3, and the output shaft of the drive motor 3 is located outside the motor shield 5. The motor shield 5 protects the motor to prevent the motor from being damaged by foreign objects.

[0042] Cleaning operation of the fork device: manually pour the material (seaweed, kelp, etc.) into the cleaning tank of the cleaning machine. The conveying device in the cleaning tank drives the material to move from right to left. During the movement, the spray device of the cleaning machine first splashes water onto the material to achieve preliminary cleaning of the material.

[0043] After that, the driving motor 3 is started, driving the rocker arm 21 to rotate counterclockwise. When the rocker arm 21 rotates to the right half circle, it first drives the connecting rod 22 to move to the right. Since the fork shaft 11 is rotated and arranged on the frame 4 of the cleaning machine, the connecting rod 22 drives the fork shaft 11 to rotate counterclockwise, thereby driving the fork mounting plate 12 to swing leftward (consistent with the direction of material movement). The fork 13 tilts to the left and penetrates into the water. The vertical rod of the fork 13 contacts the material to break up the bonded material in the water. Due to the impact of the water flow on the fork 13, in order to prevent the fork 13 from being parallel to the water surface after rotation, the fork mounting plate 12 is provided with a limiting groove 122 to support and limit the crossbar of the fork 13, thereby limiting the large-angle inclination of the fork 13, thereby making the vertical rod of the fork 13 contact the material to break up the bonded material.

[0044] When the rocker arm 21 rotates to the left half circle, the connecting rod 22 is driven to move to the left, and the connecting rod 22 drives the fork shaft 11 to rotate counterclockwise, thereby driving the fork mounting plate 12 to swing to the right (opposite to the direction of material movement), but due to the reverse thrust of the water flow, the fork 13 will remain in a vertical state, and the fork 13 will penetrate into the water under its own weight, and the vertical rod of the fork 13 will contact the material and will not bring the material back. The fork 13 swings left and right to break up the material, effectively improving the cleaning effect and efficiency of the mutually adhering materials.

[0045] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, other implementation methods can certainly be easily made by replacement or modification based on the technical contents disclosed in this specification.
