Description

Technical Field

[0001] The invention relates to the technical field of farmland fertilizer spreading, and in particular to a water-powered farmland fertilizer spreading device for a water conservancy project. Background Art

[0002] The water conservancy channel in the farmland water conservancy project is a water conveyance structure set up on the side of the farmland, and is mostly used for irrigation and water diversion projects. At present, when fertilizing rice fields and other farmland, it is inconvenient for workers to move inside the farmland, so workers usually stand around the farmland and hold fertilizer buckets to spread fertilizer on the farmland. However, this has the disadvantage that it requires a lot of manpower, the fertilizer spreading process is time-consuming and labor-intensive, the spreading distance is short, the spreading range is narrow, and it is difficult to control the amount of fertilizer to be spread, which will result in too much or too little fertilizer being thrown out.

[0003] Some automatic fertilizer spreading devices are disclosed in the prior art. For example, the patent document with the publication number CN108029305B discloses a water-powered farmland fertilizer spreading device for water conservancy projects. However, the above-mentioned device can only spread fertilizer in a single direction toward the front of the device during use. The fertilizer spreading range is relatively narrow, and manual operation is required to add fertilizer each time. The manual discloses: "When the sector gear 19 is not engaged with the first rack 27, the user can push the baffle 308 to the right, and the baffle 308 moves through the second slide The block 306 moves rightward in the second slide rail 305, compressing the second spring 307. The baffle 308 moves rightward and no longer blocks the discharge pipe 304, so that the fertilizer in the material box 303 passes through the discharge pipe 304 and falls to the left side of the placement plate 23. After the fertilizer is discharged, the user can release the baffle 308. At this time, the second spring 307 will recover from the compressed state, pushing the second slider 306 to move left, thereby driving the baffle 308 to move left, so that the baffle 308 blocks the discharge pipe 304 again.

[0004] Manual operation of adding fertilizer will result in different amounts of fertilizer added each time, resulting in uneven amounts of fertilizer spread each time. Therefore, the present invention provides a water-powered farmland fertilizer spreading device for a water conservancy project to solve the above problem. Summary of the Invention

[0040] The following will refer to the attached Figures 1-15 DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments of the present invention are described in detail.

[0041] A water power farmland fertilizer spreading equipment for water conservancy projects, as shown in the attached Figure 1-15 The hopper 2 is a kind of hopper that is fixed on the hopper 1, and the hopper 2 is a kind of hopper that is fixed on the hopper 1. The hopper 2 is a kind of hopper that is fixed on the hopper 1, and the hopper 2 is a kind of hopper that is fixed on the hopper 1.

[0042] When in use, when the fan-shaped fertilizer throwing slide 4 moves to the bracket 1, multiple discharge ports 6 are located above the fan-shaped fertilizer throwing slide 4, and the fertilizer inside the material box 2 can be automatically added to the fan-shaped fertilizer throwing slide 4 through the discharge pipe 5 and the discharge port 6 through the discharge mechanism 7. Then, the fan-shaped fertilizer throwing slide 4 can throw the fertilizer out when it moves quickly toward the front end of the fertilizer throwing base plate 3. The fan-shaped fertilizer throwing slide 4 has a fan-shaped structure, which can make the fertilizer spread in the air in a fan shape when throwing fertilizer, thereby increasing the throwing efficiency. Spreading range, when the fan-shaped fertilizer throwing slide 4 moves forward to spread the fertilizer, the baffle 8 moves forward synchronously with it, and the top surface of the baffle 8 abuts against the bottom openings of the multiple discharge ports 6, which can prevent the fertilizer from falling. When the fan-shaped fertilizer throwing slide 4 moves to the bracket 1 again, the baffle 8 opens the multiple discharge ports 6, allowing the fertilizer inside the discharge pipe 5 to fall into the fan-shaped fertilizer throwing slide 4 again, and then the fan-shaped fertilizer throwing slide 4 reciprocates multiple times, thereby realizing automatic spreading of the fertilizer;

[0043] The front side of the bracket 1 is provided with a fertilizer throwing storage mechanism 9 located below the fertilizer throwing base plate 3. The fertilizer throwing storage mechanism 9 can drive the fan-shaped fertilizer throwing slide 4 to move toward the direction of the bracket 1 and store force. When the fertilizer throwing storage mechanism 9 is separated from the fan-shaped fertilizer throwing slide 4, the fan-shaped fertilizer throwing slide 4 can quickly move toward the front end of the fertilizer throwing base plate 3 to throw fertilizer, and then the fertilizer throwing storage mechanism 9 will drive the fan-shaped fertilizer throwing slide 4 to move toward the bracket 1 again, so that the fan-shaped fertilizer throwing slide 4 performs multiple reciprocating cycles of fertilizer throwing operations;

[0044] A throwing distance adjusting mechanism 10 is provided on the left and right sides of the fertilizer throwing base plate 3. The throwing distance adjusting mechanism 10 is located on the front side of the fan-shaped fertilizer throwing slide 4, which can adjust and limit the distance that the fan-shaped fertilizer throwing slide 4 moves forward. Specifically, whenever the fan-shaped fertilizer throwing slide 4 throws fertilizer forward once and moves toward the direction of the bracket 1 again, the throwing distance adjusting mechanism 10 can be driven to move a certain distance backward on the fertilizer throwing base plate 3, thereby gradually shortening the distance that the fan-shaped fertilizer throwing slide 4 moves forward quickly to throw fertilizer, so that the fan-shaped fertilizer throwing slide 4 can spread fertilizer on the farmland from far to near;

[0045] A paddle wheel shaft 11 is rotatably mounted between the front and rear side surfaces of the bottom of the bracket 1, and a water-powered paddle wheel 12 is coaxially fixedly mounted on the paddle wheel shaft 11. The water-powered paddle wheel 12 consists of a paddle wheel and a paddle wheel blade. The paddle wheel can be composed of steel plates spliced ​​together by welding or bolting, and is mounted on the outer side of the paddle wheel shaft 11. The material of the paddle wheel blade can be a metal plate or a plastic plate. The number of paddle wheel blades is ≥6 (the number of paddle wheel blades in the drawings of this embodiment is 8, and can also be other numbers). When the bracket 1 is erected above the canal, the lower side of the water-powered paddle wheel 12 can be placed in the water flow, and the water flow The flow rate drives the water power dial 12 to rotate, and a water power driving mechanism 13 is connected between the dial shaft 11, the feeding mechanism 7 and the fertilizer throwing storage mechanism 9. When the water power dial 12 rotates, the feeding mechanism 7 can be driven to operate by the water power driving mechanism 13, so that the fertilizer inside the material box 2 is transported to the multiple feeding pipes 5 and added to the fan-shaped fertilizer throwing slide 4 from the feeding port 6. At the same time, it can also drive the fertilizer throwing storage mechanism 9 to operate, thereby driving the fan-shaped fertilizer throwing slide 4 to reciprocate on the fertilizer throwing base plate 3 to perform automatic fertilizer throwing operation, so that the above operations can be synchronized and coordinated without manual intervention;

[0046] When in use, the number of devices to be set up can be determined based on the distribution of canals around the farmland. Multiple devices can be used to spread fertilizer at the same time, or only one device can be used. When the fertilizer is spread on the farmland directly in front of the bracket 1, the bracket 1 can be moved along the canal to the farmland area where fertilizer has not been spread, and then the fertilizer can be spread.

[0047] As attached Figure 7 、 Figure 15 As shown, the cross section of the fan-shaped fertilizer throwing slide 4 is "L"-shaped, which includes a fan-shaped horizontal plate, the thickness of the front end of the horizontal plate is greater than the thickness of the rear end thereof, so that the top surface of the horizontal plate is an inclined surface with a higher front and a lower rear end, and the rear end of the top surface of the horizontal plate is fixedly installed with an arc-shaped vertical plate, and the two ends of the fan-shaped fertilizer throwing slide 4 are closed by partitions. When fertilizer falls from multiple discharge ports 6 onto the inclined surface of the horizontal plate, the fertilizer will gather along the inclined surface towards the vertical plate, thereby preventing the fertilizer from falling from the front side of the horizontal plate, and the partitions on both sides of the fan-shaped fertilizer throwing slide 4 can prevent the fertilizer from falling from both sides thereof, and due to the inclined surface setting of the horizontal plate, when the fan-shaped fertilizer throwing slide 4 is quickly started forward to throw fertilizer, the fertilizer is thrown out along the inclined surface of the horizontal plate, which can make the fertilizer produce an upward parabola, so that the fertilizer can be thrown farther;

[0048] A plurality of fan-shaped equidistantly distributed material leveling partitions 14 are fixedly installed on the front side surface of the vertical plate, so that the fertilizer falling on the horizontal plate can be evenly distributed, so that the fertilizer spread into the farmland is more evenly distributed. A plurality of fan-shaped equidistantly distributed crushing blades 15 are fixedly installed on the front end of the top surface of the horizontal plate. In order to avoid the presence of agglomerated particles in the fertilizer thrown out, which leads to uneven distribution of the fertilizer thrown into the farmland, when the fertilizer is thrown along the inclined surface of the horizontal plate, the fertilizer hits the plurality of crushing blades 15, so that the agglomerated particles in the fertilizer are crushed, thereby avoiding the above-mentioned situation of agglomerated particles in the fertilizer thrown out.

[0049] As attached Figure 3 、 Figure 6-Figure 7 、 Figure 14-15 As shown, the unloading mechanism 7 includes an unloading auger 16, and the interior of each of the unloading tubes 5 is rotatably installed with an unloading auger 16, and the unloading auger 16 extends to the interior of the material box 2, and the rear end of each of the unloading auger 16 passes through the outside of the material box 2 and is coaxially fixed with an unloading sprocket 17, and an unloading chain 18 is installed between the multiple unloading sprockets 17. Through the multiple unloading sprockets 17 and the unloading chain 18, the multiple unloading auger 16 can be rotated synchronously, and the interior of the material box 2 can be unloaded when the multiple unloading auger 16 rotates. The fertilizer is simultaneously transported to the inside of the discharge pipe 5 and falls into the fan-shaped fertilizer throwing slide 4 from multiple discharge ports 6. When the fan-shaped fertilizer throwing slide 4 moves forward quickly to throw fertilizer, the baffle 8 blocks the bottom of the multiple discharge ports 6. At this time, the multiple discharge augers 16 are still rotating and transport the fertilizer to the inside of the multiple discharge ports 6. Then, when the fan-shaped fertilizer throwing slide 4 moves below the multiple discharge ports 6 again, the fertilizer inside the multiple discharge ports 6 will fall into the fan-shaped fertilizer throwing slide 4 again, thereby achieving the effect of automatically filling the fan-shaped fertilizer throwing slide 4.

[0050] As attached Figure 9 、 Figure 14 、 Figure 15 As shown, a fertilizer throwing chute 19 is penetrated between the top and bottom surfaces of the fertilizer throwing base plate 3, and a fertilizer throwing slider 20 that slides with the fertilizer throwing chute 19 is fixedly installed at the bottom of the fan-shaped fertilizer throwing slide 4, and a fertilizer throwing power tension spring 21 is fixedly connected between the front side surface of the fertilizer throwing chute 19 and the front side surface of the fertilizer throwing slider 20. The fertilizer throwing force storage mechanism 9 can drive the fertilizer throwing slider 20 to move in the fertilizer throwing chute 19 toward the direction of the bracket 1, thereby driving the fan-shaped fertilizer throwing slide 4 to move synchronously, and can stretch the fertilizer throwing power tension spring 21 to store force. When the fertilizer throwing force storage mechanism 9 is separated from the fertilizer throwing slider 20, the elastic force of the fertilizer throwing power tension spring 21 contracts to drive the fertilizer throwing slider 20 and the fan-shaped fertilizer throwing slide 4 to move forward quickly, thereby throwing the fertilizer out.

[0051] As attached Figures 8-10 、 Figure 12-15As shown, the fertilizer throwing storage mechanism 9 includes a storage bracket 22 fixedly mounted on the front side of the bracket 1 and located below the fertilizer throwing base plate 3. The storage bracket 22 can be mounted on the front side of the bracket 1 by welding or bolting. The number of the storage brackets 22 is two symmetrical left and right. The front and rear ends of the storage bracket 22 are rotatably mounted with a storage axle 23. Each storage axle 23 is rotatably mounted between the two storage brackets 22. A plurality of storage sprockets 24 are coaxially fixedly mounted on each of the storage axles 23. The gear positions of the plurality of storage sprockets 24 on each of the storage axles 23 correspond to each other on the left and right, and can rotate synchronously. A storage chain 25 is installed between every two front and rear corresponding storage sprockets 24. Each storage axle in the drawings of this embodiment The number of the power storage sprockets 24 on 23 is 3, and the number of the power storage chains 25 is also 3, and can also be set to other numbers as needed. The position of each link of the three power storage chains 25 corresponds to the left and right, and can rotate synchronously. A power storage wedge-shaped shifting block 26 is fixedly installed on the outside of the multiple power storage chains 25. Mounting plates located on the outside of the three power storage chains 25 are installed on both sides of the power storage wedge-shaped shifting block 26, and are fixedly installed by two pins passing through the holes of the chain links, so that they can follow the circumferential movement of the power storage chain 25. The number of the power storage wedge-shaped shifting blocks 26 is multiple. In the drawings of this embodiment, the number of the power storage wedge-shaped shifting blocks 26 is three. The bottom of the fertilizer throwing slider 20 is fixedly installed with a wedge-shaped push block 27, which can move synchronously with the fertilizer throwing slider 20;

[0052] Reference Attachment Figure 10 and Figure 14 When in use, the fertilizer throwing slider 20 is at the front end of the fertilizer throwing chute 19, and the two power storage wheel shafts 23 drive the power storage sprocket 24 and the power storage chain 25 to rotate clockwise, and the power storage wedge-shaped shifting block 26 abuts against the wedge-shaped pushing block 27 (see attached Figure 10 The force storage chain 25 rotates clockwise through the force storage wedge-shaped shifting block 26 to drive the wedge-shaped push block 27 and the fertilizer throwing slider 20 to move toward the direction of the bracket 1 (the fertilizer throwing power tension spring 21 is stretched and starts to store force), thereby driving the fan-shaped fertilizer throwing slide 4 to move synchronously. When the fertilizer throwing slider 20 moves to the rear end of the fertilizer throwing chute 19, the force storage wedge-shaped shifting block 26 is separated from the wedge-shaped push block 27 (see the attached Figure 14 The fertilizer throwing slider 20 can move forward quickly under the elastic force of the fertilizer throwing power tension spring 21, thereby driving the fan-shaped fertilizer throwing slide 4 to move forward quickly to perform the fertilizer throwing operation, and then the power storage chain 25 continues to rotate to make the next power storage wedge-shaped shifting block 26 abut against the wedge-shaped pushing block 27 to drive the fertilizer throwing slider 20 to move, thereby driving the fan-shaped fertilizer throwing slide 4 to perform a reciprocating fertilizer throwing operation.

[0053] As attached Figures 8-10 、 Figure 13As shown, the right end of the power storage wheel shaft 23 located at the rear end of the power storage bracket 22 is coaxially fixedly connected with a power storage worm gear 28, and the power storage worm gear 28 can rotate synchronously with the above-mentioned power storage wheel shaft 23. A power storage drive shaft 29 is rotatably installed on the front side surface of the bracket 1, and a power storage worm 30 meshing with the power storage worm gear 28 is coaxially fixedly installed on the front end of the power storage drive shaft 29. The power storage worm gear 30 can rotate synchronously with the power storage drive shaft 29. When the power storage worm gear 30 rotates, it can drive the power storage worm gear 28 to rotate, thereby driving the power storage wheel shaft 23 to rotate, and the power storage wheel shaft 23 drives the power storage sprocket 24 and the power storage chain 25 to rotate.

[0054] As attached Figures 8-10 、 Figure 13-14 As shown, the cast distance adjustment mechanism 10 includes a cast distance limiting groove 31 passing through the fertilizer throwing chute 19 and the left and right side surfaces of the fertilizer throwing base plate 3, and a cast distance limiting plate 32 is installed in the two cast distance limiting grooves 31 for sliding back and forth. The ends of the two cast distance limiting plates 32 close to each other are both inside the fertilizer throwing chute 19 and in front of the fertilizer throwing slider 20. Two screw mounting plates are installed on the left and right side surfaces of the fertilizer throwing base plate 3, and a cast distance adjustment screw 33 is rotatably installed between the two screw mounting plates on the same side. The cast distance limiting plate 32 is threadedly connected to the cast distance adjustment screw 33 on the same side.

[0055] During use, the fertilizer throwing slider 20 can be blocked by the two throwing distance limit plates 32 each time it moves forward quickly. Each time the fan-shaped fertilizer throwing slide 4 moves backward, the two throwing distance adjusting screw rods 33 are rotated synchronously to drive the two throwing distance limit plates 32 to move backward synchronously a certain distance, thereby gradually shortening the distance that the fertilizer throwing slider 20 and the fan-shaped fertilizer throwing slide 4 move forward quickly, so that the fan-shaped fertilizer throwing slide 4 can spread fertilizer from far to near.

[0056] As attached Figures 8-10 、 Figure 13 As shown, the rear end of the pitch adjustment screw rod 33 is coaxially fixedly installed with a pitch adjustment bevel gear 34, and the pitch adjustment bevel gear 34 can rotate synchronously with the pitch adjustment screw rod 33. The left and right side surfaces of the fertilizer throwing substrate 3 are rotatably installed with a pitch driving bevel gear 35 that meshes with the pitch adjustment bevel gear 34. When the pitch driving bevel gear 35 rotates, it can drive the pitch adjustment bevel gear 34 to rotate. Each of the pitch driving bevel gears 35 is coaxially fixedly installed with a one-way gear 36. The one-way gear 36 consists of an inner wheel and an outer gear ring. A ratchet structure is installed between the inside of the two, so that the one-way gear 36 can only rotate in one direction as a whole. When it rotates in the other direction, only its outer gear ring can rotate (refer to the sprocket structure of the rear wheel of a bicycle);

[0057] Reference Attachment Figure 10 With attached Figure 13The one-way gear 36 in this embodiment can rotate clockwise as a whole and drive the pitch driving bevel gear 35 to rotate, thereby driving the pitch adjusting screw rod 33 to rotate, so that it drives the pitch limiting plate 32 to move a certain distance backward, while the outer gear ring of the one-way gear 36 can rotate counterclockwise. At this time, it cannot drive the pitch driving bevel gear 35 to rotate. Two pitch adjusting racks 37 with left-right symmetry and capable of meshing with the two one-way gears 36 are fixedly installed on the bottom surface of the sector-shaped fertilizer throwing slide 4;

[0058] When using (or refer to Figure 10 and Figure 13 ), when the fan-shaped fertilizer throwing slide 4 moves toward the direction of the bracket 1, the two pitch adjustment racks 37 at the bottom thereof can mesh with the two one-way gears 36, and drive the two one-way gears 36 to rotate clockwise as a whole, thereby driving the two pitch driving bevel gears 35 to rotate synchronously, and the two pitch driving bevel gears 35 drive the two pitch adjustment bevel gears 34 and the pitch adjustment screw rod 33 to rotate synchronously, and the two pitch adjustment screw rods 33 drive the two pitch limit plates 32 to move synchronously a certain distance backward;

[0059] When the fan-shaped fertilizer throwing slide 4 moves forward quickly to spread the fertilizer, the two pitch adjustment racks 37 at the bottom drive the outer gear rings of the two one-way gears 36 to rotate. At this time, the two one-way gears 36 cannot drive the two pitch driving bevel gears 35 to rotate. Therefore, the positions of the two pitch limit plates 32 remain unchanged, and the fertilizer throwing slide 20 moves forward quickly until it abuts against the two pitch limit plates 32.

[0060] In order to ensure that when the two pitch adjustment racks 37 move forward and drive the outer gear rings of the two one-way gears 36 to rotate, the inner wheel of the one-way gear 36 is prevented from rotating counterclockwise due to inertia, a rubber friction plate can be installed on one side of the inner wheel of the one-way gear 36, and the other side of the rubber friction plate is in contact with the side surface of the fertilizer throwing base plate 3, thereby increasing the friction force of the inner wheel of the one-way gear 36. When the outer gear ring of the one-way gear 36 rotates, its inner wheel does not rotate. When the pitch adjustment rack 37 drives the one-way gear 36 to rotate clockwise as a whole, the rubber friction plate can rotate synchronously with the one-way gear 36.

[0061] When the fertilizer throwing slider 20 and the fan-shaped fertilizer throwing slide 4 move toward the bracket 1 again, the two throw distance adjustment racks 37 at the bottom drive the two one-way gears 36 to rotate as a whole again, and drive the two throw distance driving bevel gears 35 to rotate synchronously, so that the two throw distance limit plates 32 move backward again by a certain distance, thereby gradually shortening the distance that the fertilizer throwing slider 20 and the fan-shaped fertilizer throwing slide 4 move forward quickly, achieving the effect of spreading fertilizer from far to near.

[0062] As attached Figures 1-6 、 Figure 11As shown, the water power driving mechanism 13 includes a large driving sprocket 38 coaxially fixedly mounted on the dial shaft 11, and a storage driving sprocket 39 coaxially fixedly mounted on the rear end of the power storage driving shaft 29. A driving chain 40 is installed between the large driving sprocket 38 and the power storage driving sprocket 39. When the water flow drives the water power dial 12 and the dial shaft 11 to rotate, the large driving sprocket 38 can be driven to rotate synchronously. The large driving sprocket 38 drives the power storage driving sprocket 39 to rotate through the driving chain 40. The power storage driving sprocket 39 drives the power storage driving shaft 29 to rotate. The power storage driving shaft 29 drives the power storage worm 30 to rotate, thereby realizing the reciprocating fertilizer throwing motion of the fan-shaped fertilizer throwing slide 4.

[0063] The rear end of the power storage drive shaft 29 is coaxially fixedly installed with a discharge drive sprocket 41, and the power storage drive shaft 29 can rotate synchronously with the discharge drive sprocket 41. A discharge drive chain 42 is installed between the discharge drive sprocket 41 and one of the discharge sprockets 17, and one of the discharge sprockets 17 can be coaxially fixedly connected with a sprocket, and one end of the discharge drive chain 42 is cooperated with the above-mentioned sprocket. When the power storage drive shaft 29 and the discharge drive sprocket 41 rotate synchronously, the discharge drive chain 42 can drive multiple discharge sprockets 17 to rotate synchronously, so that multiple discharge augers 16 rotate synchronously to transport fertilizer to the inside of multiple discharge pipes 5. Through the arrangement of the above-mentioned structure, the reciprocating fertilizer throwing movement of the fan-shaped fertilizer throwing slide 4 and the fertilizer transportation inside multiple discharge pipes 5 can be carried out synchronously and coordinated.

[0064] As attached Figures 1-6 、 Figure 11 As shown, vertical lifting rails 43 are fixedly installed on the front and rear sides of the bottom of the bracket 1, and a lifting slider 44 is installed in each of the lifting rails 43 for sliding up and down. The dial shaft 11 is rotatably installed between the opposite sides of the two lifting sliders 44 through a bearing, and a guide rod passing through the lifting slider 44 is installed between the upper and lower sides of each lifting rail 43. A lifting spring 45 is fixedly connected between the top surface of each lifting slider 44 and the top surface of the lifting rail 43. The lifting spring 45 is on the outside of the guide rod. When the lifting slider 44 moves upward, it can compress the lifting spring 45. The compressed lifting spring 45 is restricted by the guide rod and will not pop out to the outside of the lifting rail 43.

[0065] When the device is not needed or needs to be moved, the two lifting sliders 44 can be moved upward to drive the water-powered dial 12 to move upward so that it leaves the water flow and moves to the inside of the bracket 1. At the same time, the two lifting sliders 44 compress the two compression lifting springs 45. The water-powered dial 12 stops rotating after leaving the water flow, and then the device can be moved to another place by the moving wheel. When it is used again, the two lifting sliders 44 are moved downward to the bottom of the lifting slide rail 43 to make the water-powered dial 12 enter the water flow again. The two lifting springs 45 provide elastic force to the two lifting sliders 44 so that the water-powered dial 12 will not move upward out of the water flow when working.

[0066] A transverse lifting drive rail 46 is fixedly installed on the front side of the bracket 1, and two lifting screw blocks 47 are slidably installed in the lifting drive rail 46. A lifting sprocket 48 is rotatably installed on the rear side of each lifting screw block 47, and the two lifting sprockets 48 are located on the inner side of the driving chain 40 and mesh with the driving chain 40. A double-headed screw rod 49 is rotatably installed between the left and right side surfaces of the lifting drive rail 46. The two lifting screw blocks 47 are respectively threadedly connected to the two ends of the double-headed screw rod 49. The threads at the two ends of the double-headed screw rod 49 are in opposite directions, and when it rotates, it can drive the two lifting screw blocks 47 to move relative to or away from each other;

[0067] When it is necessary to move the water-powered dial 12 upward out of the water flow and lift it into the bracket 1, the double-headed screw 49 can be rotated to drive the two lifting screw blocks 47 to move in opposite directions, and the two lifting sprockets 48 can move the left and right parts of the driving chain 40 to the left and right sides. The driving chain 40 drives the large driving sprocket 38 to move upward, so that the dial shaft 11, the water-powered dial 12 and the two lifting sliders 44 also move upward synchronously (the two lifting sliders 44 compress the two lifting springs 45 to store force), so that the water-powered dial 12 moves upward out of the water flow and lifts it into the bracket 1.

[0068] When it is necessary to use this device, the double-headed screw 49 can be rotated to drive the two lifting screw blocks 47 to move relative to each other, and the two drive the two lifting sprockets 48 to move closer to each other. The two lifting sprockets 48 also move closer to each other, and the left and right sides of the drive chain 40 are closed inward. At the same time, the elastic force of the two lifting springs 45 causes the two lifting sliders 44 to move downward, thereby driving the dial shaft 11, the water-powered dial 12 and the driving large sprocket 38 to move downward, so that the water-powered dial 12 enters the water flow, and the water-powered dial 12 is driven to rotate by the water flow, and the subsequent structure is driven to operate by driving the large sprocket 38 and the driving chain 40.
