Description

Technical Field

[0001] The present invention relates to the technical field of ditch desilting equipment, in particular to a water conservancy ditch desilting device. Background Art

[0002] A ditch is a waterway dug for irrigation and drainage. During the irrigation or drainage process, due to the presence of a certain amount of mud or dirt in the water, silt will accumulate in the ditch over a long period of time. Excessive silt will lead to poor drainage effect of the ditch.

[0003] In order for the ditch to operate normally, people need to clean the silt in the ditch. At present, people shovel it out manually or use some cleaning tools to clean the ditch. It is very inconvenient to clean the silt in the ditch manually, and people need to stand in the silt to work, which is less safe.

[0004] Publication number CN113982057B provides an intelligent automatic silt clearing device for civil engineering and water conservancy construction. When the trolley body is pushed, the silt in the drainage ditch can be pushed into the silt clearing frame, and when the silt clearing frame is driven upward by the winch motor, the silt can be discharged into the silt storage frame. However, when in use, the following shortcomings still exist: 1. When working, the wheels need to be stuck in the silt at the bottom, which will cause difficulty in movement. If normal movement is required, the moving wheels can only be stuck on the side wall of the water conservancy ditch, and the device cannot achieve this function; 2. The cleared silt can only be stored in the silt storage frame. Once the silt storage frame is full, it needs to be cleaned, which is very troublesome and the silt cannot be directly discharged to both sides of the ditch. Summary of the Invention

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] Example:

[0036] See also Figures 1 to 9 , the present invention provides a technical solution:

[0037] A water conservancy ditch desilting device includes a motion mechanism 10, a cleaning box 20, a locking mechanism 30, a cleaning bucket 40, a conveyor belt mechanism 50, a discharge box 60 and a discharge mechanism 70, wherein:

[0038] The motion mechanism 10 is provided with two groups and is symmetrically installed on both sides of the cleaning box 20. The front end referred to in this embodiment is the direction close to the cleaning bucket 40, and the rear end is the direction away from the cleaning bucket 40. Each group of motion mechanisms 10 includes a motion box 11. The motion box 11 is provided with at least two independent motion wheels 12. The motion wheels 12 protrude from the motion box 11. The motion wheels 12 are fixed on the motion shaft 13. The two ends of the motion shaft 13 are fixed to the inner wall of the motion box 11 through bearing seats. When the motion wheel 12 rotates, the motion shaft 13 rotates in the bearing seats at both ends as the motion wheel 12 rotates. Two connecting brackets 18 are fixed to the outside of the motion box 11, and each connecting bracket 19 is fixed with a rotating shaft 19.

[0039] When the moving wheel 12 rotates, the entire silt removal device moves along with the moving wheel 12. The moving wheel 12 is not a single forward driving device, and the entire device can be driven to move forward under the action of external power.

[0040] Furthermore, a driven bevel gear 14 is fixed on the motion shaft 13, and a motion motor 17 is fixed to the outside of the motion box 11. The rotating shaft of the motion motor 17 and the drive shaft 15 are coaxially connected. The drive shaft 15 is fixed to the inner wall of the motion box 11 through a bearing seat. A driving bevel gear 16 is fixed to the drive shaft 15. The drive shaft 15 and the motion shaft 13 are vertically arranged. The driving bevel gear 16 and the driven bevel gear 14 are meshed and connected. The teeth of the driving bevel gear 16 and the driven bevel gear 14 are meshed and connected with each other. When the motion motor rotates, it drives the drive shaft 15 to rotate on the bearing seat, and the driving bevel gear 16 rotates accordingly. Power is transmitted between the driving bevel gear 16 and the driven bevel gear 14, driving the motion shaft 13 to rotate, thereby driving the motion wheel 12 to move, and driving the dredging device to move.

[0041] The upper and lower ends of the cleaning box 20 are open, and fixed bearing seats 21 are symmetrically provided on the front and rear ends of the outside. The rotating shaft 19 is installed in the fixed bearing seat 21 and can rotate around the fixed bearing seat 21. When the rotating shaft 19 rotates, the entire motion mechanism connected to it can rotate, thereby adjusting the inclination angle of the motion mechanism 10 on both sides of the cleaning box 20. When the inclination angle is larger, the distance between the motion wheels 12 on both sides is larger. The inclination angle of the motion wheel 12 can also be adjusted so that it can fit closely to the side wall of the water conservancy ditch, thereby meeting the needs of various water conservancy ditches with V-shaped and trapezoidal cross-sections. The inclination angle of the motion wheels 12 on both sides of the cleaning box 20 and the distance between the motion wheels 12 on both sides are adjusted according to needs. It can be suitable for the width of various water conservancy ditches and the inclination angle of the side walls, so that the motion wheels 12 can be well stuck on both sides of the water conservancy ditch, which is convenient for driving the entire device to move.

[0042] Furthermore, a limit plate 23 perpendicular to the outer wall of the cleaning box 20 is fixed to the outside of the cleaning box 20. The limit plate 23 is located directly above the connecting bracket 18. When the rotating shaft 19 rotates, the connecting bracket 18 rotates accordingly. When the connecting bracket 18 touches the limit plate 23, it cannot rotate, thereby limiting the entire motion mechanism 10 from flipping upward excessively.

[0043] The locking mechanism 30 is fixed to the outside of the cleaning box 20 and is connected to the rotating shafts 19 of the two motion mechanisms 10 respectively, so as to limit the rotation of the rotating shafts 19 .

[0044] The cam 32 is provided with two cams 33 and a cam 34 for camming the cam 33 so as to enable the cam 33 to rotate freely.

[0045] A locking rod 33 is fixed to the middle of the rotating rod 32, and an adjusting rod 34 is sleeved on one end of the locking rod 33. The interfaces between the locking rod 33 and the adjusting rod 34 are both regular hexagons, and the diameter of the adjusting rod 34 is larger than the locking rod 33. A locking fork 37 is sleeved on the end of the locking rod 33 away from the adjusting rod 34, and a guide rod 39 is fixed on the support frame 31 near the locking fork 37. The guide rod 39 passes through the locking fork 37, and the locking fork 37 can move along the guide rod 39. A locking spring 38 is sleeved on the guide rod 39 between the locking fork 37 and the support frame 31. The side wall of the cleaning box 20 is provided with and The guide rod 39 is parallel to the sliding groove 22, and one end of the locking fork 37 is stuck in the sliding groove 22. When the locking fork 37 moves along the guide rod 39, it slides synchronously along the sliding groove 22. When the locking fork 37 is sleeved on the locking rod 33, the rotating rod 32 cannot rotate. When the locking fork 37 is pushed to move along the guide rod 39, the locking spring 38 is compressed, and the locking fork 37 is disengaged from the locking rod 33. At this time, the rotating rod 32 can rotate normally to adjust the inclination angle of the motion mechanism 10. When the push is stopped, the elastic force of the locking spring 38 is released, and the locking fork 37 is re-stuck on the locking rod 33.

[0046] Optionally, the locking mechanism 30 can also be selected as a screw installed on the fixed bearing seat 21 according to needs. When there is no need to adjust the inclination angle of the motion mechanism 10, the screw is tightened and passes through the fixed bearing seat 21, and the head is against the side of the rotating shaft 19. Under the action of friction, the rotating shaft 19 cannot rotate. When it is needed to rotate, the screw can be loosened.

[0047] The cleaning bucket 40 is arranged downwardly and tilted toward the front end, with one end fixed inside the cleaning box 20 and the other end extending out of the cleaning box 20 from the front end of the cleaning box 20. When the entire dredging device is working, the front end of the cleaning bucket 40 contacts the silt at the bottom of the water conservancy ditch to be cleaned, scoops up the silt, and transports it to the conveying mechanism 50 under the continuous squeezing of the silt at the front end.

[0048] The conveyor belt mechanism 50 includes a conveyor belt 51 that is inclined upward toward the rear end and a conveying motor 52. The conveyor belt 51 is fixed inside the cleaning box 20, and the bottom end is fixed below one end of the cleaning bucket 40 located in the cleaning box 20, and the other end extends into the discharge box 60. The conveying motor 52 and the rotating roller of the transmission belt 51 are coaxially connected. When the conveying motor 52 rotates, it drives the conveyor belt 51 to move, and the silt inside the cleaning bucket 40 falls to the front end of the conveyor belt 51 and moves obliquely upward along the conveyor belt 51.

[0049] Furthermore, a material storage plate 53 perpendicular to the conveying direction is fixed on the conveyor belt surface of the conveyor belt 51 , and the material storage plate 53 has a blocking effect on the silt so that it does not slide on the surface of the conveyor belt 51 .

[0050] The discharge box 60 is fixed at the rear end of the cleaning box 20, and a feed port 61 is provided near the side of the cleaning box 20. The conveyor belt 51 extends into the discharge box 60 through the feed port 61. The conveying motor 52 is fixed on the outside of the discharge box 60. A discharge port 62 is provided on the side wall of the discharge box 60 perpendicular to the direction of the feed port 61. The sludge transported by the conveyor belt 51 falls into the discharge box 60 at the rear end.

[0051] The discharge mechanism 70 includes a rotating barrel 71 and a rotating motor 72. A discharge port 73 is provided on the side wall of the rotating barrel 71. The discharge port 73 and the discharge port 62 are at the same height. The rotating motor 72 is fixed to the bottom of the discharge box 60, and the rotating shaft of the rotating motor 72 is coaxially connected to the rotating barrel 71. The upper end of the rotating barrel 71 is open and is located below the upper end of the conveyor belt 51. The sludge that falls into the discharge box 60 will directly fall into the interior of the rotating barrel 71, and the rotating barrel 71 rotates under the drive of the rotating motor 72.

[0052] Furthermore, a bull's eye universal ball wheel 75 is fixed to the upper end of the bottom of the discharge box 60, and the bottom of the rotating barrel 71 rests on the ball of the bull's eye universal ball wheel 75. The bull's eye universal ball wheel 75 supports the rotating barrel 71 at the bottom, making its movement smoother without affecting its normal rotation.

[0053] The silt that falls into the rotating barrel 71 is thrown out from the discharge port 73 and the discharge port 62 as the rotating barrel 71 rotates continuously. Under the action of centrifugal force, the silt has a certain initial velocity and can be thrown on both sides of the water conservancy ditch without the need for separate cleaning. The power supply for the motion motor 17, the conveying motor 52 and the rotating motor 72 can be provided by the outside, or a battery or other power supply can be set on the dredging device.

[0054] Furthermore, a brush 74 is fixed to the inner wall of the discharge box 60, and the brush 74 is located between the discharge box 60 and the rotating barrel 71, with the bristles facing the rotating barrel 71. When the discharge port 73 and the discharge port 62 do not overlap, even if the sludge is thrown out from the discharge port 73, it will not be thrown out. The brush 74 acts as a barrier on the outside to prevent the sludge from being thrown out from the discharge port 73 and accumulating inside the discharge box 60 when the discharge port 73 and the discharge port 62 do not overlap.

[0055] The operating principle of the present invention is as follows: before use, first push the locking fork 37 to make it move along the guide rod 39, the locking spring 38 is compressed, and the locking fork 37 disengages the locking rod 33. At this time, the rotating rod 32 can rotate normally. By using a wrench to rotate the adjusting rod 34, the rotating rod 32 is driven to move, and the inclination angle of the moving mechanism 10 is adjusted. Then, the inclination angle of the moving wheels 12 on both sides of the cleaning box 20 and the distance between the moving wheels 12 on both sides are adjusted as needed to make them suitable for the width of the water conservancy ditch and the inclination angle of the side wall, so that the moving wheels 12 can be well stuck on both sides of the water conservancy ditch. Then, stop pushing the locking fork 37, the elastic force of the locking spring 38 is released, and the locking fork 37 is stuck on the locking rod 33 again.

[0056] The motion motor 17 is started, and the motion motor 17 drives the entire device forward. The front end of the cleaning bucket 40 contacts the silt at the bottom of the water conservancy ditch to be cleaned, scoops up the silt, and under the continuous squeezing of the silt at the front end, conveys it to the conveyor belt 51. The silt inside the cleaning bucket 40 falls to the front end of the conveyor belt 51 and moves obliquely upward along the conveyor belt 51.

[0057] The silt transported by the conveyor belt 51 falls into the discharge box 60 at the rear end. The silt that falls into the discharge box 60 will directly fall into the inside of the rotating barrel 71. The rotating barrel 71 rotates under the drive of the rotating motor 72. The silt that falls into the rotating barrel 71 is thrown out from the discharge port 73 and the discharge port 62 as the rotating barrel 71 rotates continuously. Under the action of centrifugal force, the silt has a certain initial velocity and can be scattered on both sides of the water conservancy ditch without the need for separate cleaning.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
