Description

Technical Field

[0001] The utility model relates to the technical field of irrigation channel sludge cleaning, in particular to an irrigation channel bottom sludge cleaning device. Background Art

[0002] As irrigation channels are eroded, silt will accumulate at the bottom of the river, which will affect the flow of the river and the water quality of the irrigation channels. In order to avoid the above problems, the side walls and bottom of the irrigation channels are usually reinforced by concrete structures or brick paving to reduce the presence of silt. However, as the irrigation channels are used, silt will accumulate in the irrigation channels, so the silt in the irrigation channels needs to be cleaned regularly.

[0003] Cleaning is mainly concentrated in the dry season. During the dry season, there is no water or very little water in the irrigation channel, which makes it convenient to clean the bottom and side walls of the irrigation channel with silt.

[0004] At present, the cleaning methods mainly include manual cleaning or excavator cleaning. Manual cleaning is inefficient and labor-intensive; excavator cleaning requires high operating skills. The excavator uses mechanical claws to dig and scrape the silt in the irrigation canal on the bank of the irrigation canal or in the irrigation canal to clean the silt in the irrigation canal, which is easy to cause damage to the interior of the irrigation canal and wear on the mechanical claws of the excavator.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] See also Figure 1-5 , the utility model provides a technical solution: a sludge cleaning device at the bottom of an irrigation canal, comprising: a middle scraper 1, a side scraper 6;

[0030] The middle scraper 1 is placed horizontally, and a connecting piece 3 is provided on the front wall of the middle scraper 1. The side scrapers 6 are located on the left and right sides of the rear wall of the middle scraper 1. The lower side of the middle scraper 1 is rotatably connected to the lower side of the side scraper 6 through a pin shaft. A conveying trough is opened on the lower side of the rear wall of the side scraper 6, and a sludge transmission mechanism is provided in the conveying trough. The sludge transmission mechanism includes rollers 8 installed on both sides of the conveying trough, and a conveying belt 7 is sleeved on the outer walls of the two rollers 8. A scraping strip 9 is provided on the outer wall of the conveying belt 7. A driving motor 10 is installed on the upper side wall of the side scraper 6, and the output shaft of the driving motor 10 is connected to one of the rollers 8.

[0031] Analysis of the above content: When in use, the connector 3 is connected to the driving mechanical equipment, and the driving mechanical equipment can be agricultural machinery or a special vehicle. The length of the middle scraper 1 is set to be the same or similar to the length of the bottom of the irrigation canal, and the side scrapers 6 are inclined to both sides and attached to the inner side walls of the irrigation canal. The side scraper 6 drives the mechanical equipment to push the middle scraper 1 and the side scraper 6 through the connector 3. The middle scraper 1 and the side scraper 6 scrape the silt on the bottom and side walls of the irrigation canal at the same time. As the accumulation amount increases, the silt at the bottom will flow to the side scrapers 6 on both sides. The drive motor 10 outputs and drives the roller 8, the conveyor belt 7, and the scraper bar 9 to rotate. The scraper bar 9 pushes the silt to the upper side bank, so that the silt comes ashore.

[0032] Embodiment 2:

[0033] See also Figure 1-5The utility model provides a technical solution based on the first embodiment: a mounting groove is provided on the front side of the lower surface of the intermediate scraper 1, a lower support roller 2 is rotatably connected to the mounting groove via a rotating shaft, and the lower side of the lower support roller 2 protrudes to the lower side of the intermediate scraper 1.

[0034] Analysis of the above content: the lower support roller 2 is supported at the lower side. When the intermediate scraper 1 moves, the lower support roller 2 is rollingly supported at the inner bottom end of the irrigation channel. The friction can be reduced through the rolling support. The gap between the lower side of the intermediate scraper 1 and the bottom end of the irrigation channel has little effect on the cleaning of the irrigation channel silt and can be ignored.

[0035] Embodiment three:

[0036] See also Figure 1-5 The utility model provides a technical solution based on the first embodiment: an upper baffle plate 4 is transversely arranged in the middle of the rear side wall of the intermediate scraper plate 1, and the distance between the end of the upper baffle plate 4 and the side edge of the intermediate scraper plate 1 is the width of the side scraper plate 6.

[0037] Analysis of the above content: The upper baffle 4 blocks the accumulated silt from the upper side to prevent the silt from being too high and overflowing the middle scraper 1. When the equipment is in use, the side scraper 6 is erected so that the side scraper 6 is attached to the side of the upper baffle 4, and the upper baffle 4 and the side scraper 6 are fixed by bolts.

[0038] Embodiment 4:

[0039] See also Figure 1-5 The utility model provides a technical solution based on the third embodiment: a guide block 5 is arranged on the lower side of the rear side wall of the intermediate scraper 1, and the guide block 5 is a triangular cone with a high middle and low sides.

[0040] Analysis of the above content: The setting of the guide block 5 can promote the silt to be guided to both sides, making it convenient for the silt to be guided ashore from the side scraper 6.

[0041] Embodiment five:

[0042] See also Figure 1-5 The utility model provides a technical solution based on the first embodiment: a support groove is opened on the upper side of the lower side of the side scraper 6, and a side support roller 11 is rotatably installed in the support groove through a support shaft, and the side support roller 11 protrudes to the outside of the support groove.

[0043] Analysis of the above content: The role of the side support roller 11 is similar to that of the lower support roller 2. The side support roller 11 can be directly supported on the side wall inside the irrigation channel. When the side scraper 6 moves, the friction between the side wall and the side wall inside the irrigation channel can be reduced.

[0044] Embodiment six:

[0045] See also Figure 1-5 The utility model provides a technical solution based on the first embodiment: the connecting member 3 is a U-shaped frame with a hollow interior and an opening at the front, and a connecting pin is arranged inside the connecting member 3.

[0046] Analysis of the above content: Usually, agricultural machinery is provided with a connection seat for connecting the carriage, and a pin hole is provided on the connection seat, and the pin hole can be connected with the connection member 3 of this solution through a connection pin, and the connection member 3 can adjust the angle, size, installation position and shape according to the position of the pin hole of the agricultural machinery. If a special vehicle is provided, it can be directly connected.
