Description

Technical Field

[0001] This utility model relates to the field of farmland drainage technology, specifically to a farmland drainage filtration device. Background Technology

[0002] Farmland refers to land used for planting crops or for agricultural production. Its core characteristic is that it serves agricultural production, distinguishing it from other land types such as forest land, grassland, and construction land. Based on topography, water sources, and utilization methods, farmland can be divided into dry land, paddy fields, irrigated land, terraced fields, dammed land, or polder fields. Among them, paddy fields, specific irrigated land, dammed land, or polder fields mostly use drainage equipment to dynamically adjust the water level according to the crops.

[0003] The aforementioned devices lack the structure for drainage pipe filtration and discharge, as well as drainage pipe level adjustment. This means that when existing drainage pipes are used to drain farmland, they are mostly placed directly in the farmland for pumping and discharge. However, due to the large amount of silt and dead leaves in the farmland, debris can easily enter the drainage pipe and drainage equipment during the pumping process, causing damage. Furthermore, the inlet end of the drainage pipe has a large suction force and a fast water flow, which can carry a large amount of silt from below and near the inlet end of the drainage pipe into the pipe or drainage equipment, causing blockages. Based on the shortcomings of existing technology, this utility model designs a farmland drainage filtration device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a farmland drainage filtration device that has the advantages of drainage pipe filtration and discharge as well as drainage pipe level adjustment.

[0005] This utility model provides the following technical solution: a farmland drainage filtration device, including a water pumping pipe, a bottom support plate is provided below the water pumping pipe, and a filtration mechanism that facilitates filtration off the ground is provided above the bottom support plate.

[0006] The filtration mechanism includes a filter cartridge body, side plates, a limiting rod, a limiting cylinder, a locking bolt, a through hole, an adjusting head, a bolt, and a threaded cylinder. The filter cartridge body is sleeved on the outside of the water inlet end of the pumping pipe. Two side plates are fixedly connected to the outer surface of the filter cartridge body. The limiting rod is fixedly connected to the lower surface of a single side plate. The limiting cylinder is fixedly connected to the upper surface of the base plate. The locking bolt is threaded through and inserted into the top side wall of the limiting cylinder. The through hole is opened through another side plate. The adjusting head is rotatably disposed in the through hole. The bolt is fixedly connected to the bottom of the adjusting head. The threaded cylinder is fixedly connected to the upper surface of the base plate.

[0007] By setting up a filter cartridge body above the base plate, it is possible to pump, filter and discharge water from farmland. By setting up side plates, through holes, adjusting heads, bolts and threaded cylinders, the distance between the filter cartridge body and the base plate can be controlled, thereby controlling the water level after pumping and discharging from farmland.

[0008] As a preferred technical solution of this utility model, the bottom support plate is provided with four fixing blocks around its perimeter, and a rotating groove is provided through the fixing block. A fixing nail is inserted through the rotating groove, and a clip is fixedly connected to the top of the fixing nail.

[0009] By setting a base plate, and fixing a limiting cylinder and a threaded cylinder on the base plate, the filter cartridge body can be vertically fixed above the base plate for filtration and drainage after the base plate is placed in the farmland.

[0010] As a preferred technical solution of this utility model, a baffle is fixedly connected to the bottom inlet of the pumping pipe, a split hoop is clamped and fixedly installed on the outer wall of the pumping pipe, a connecting seat is provided on the split hoop, a buckle plate is fixedly connected to the side wall of the split hoop, a fixing plate is fixedly connected to the top edge of the filter cartridge body, a fixing bolt is provided on the fixing plate, and a sealing ring is provided on the lower surface of the split hoop.

[0011] The separate hoop and connecting seat are designed to facilitate the connection of the separate hoop to the pumping pipe.

[0012] As a preferred embodiment of this utility model, the water inlet filter hole of the filter cartridge body is located at the bottom.

[0013] As a preferred embodiment of this utility model, the limiting rod is slidably inserted into the limiting cylinder, the inner end of the locking bolt is in contact with the side wall of the limiting rod, and the bolt is threadedly connected to the threaded cylinder.

[0014] By setting up side plates, limit rods, limit cylinders, and locking bolts, the limit rods and limit cylinders can assist in limiting the lifting and lowering of the filter cartridge body when the bolts and threaded cylinders control the lifting and lowering of the filter cartridge body, and the locking bolts can assist in locking the height of the filter cartridge body.

[0015] As a preferred embodiment of this utility model, the clamp head is rotatably engaged inside the rotating groove.

[0016] By setting up troughs, fixing nails, and clips, the bottom support plate can be secured to prevent it from tipping over or shifting during the pumping and drainage process due to excessive silt in the farmland.

[0017] As a preferred embodiment of this utility model, the fixing bolt is snapped onto the buckle plate.

[0018] Fixing bolts and buckles are used to connect the split hoop to the filter cartridge body.

[0019] As a preferred embodiment of this utility model, the split hoop is disposed on the upper surface of the filter cartridge body, and the sealing ring is fixedly connected between the filter cartridge body and the split hoop.

[0020] By setting a split hoop and a sealing ring, the sealing performance between the split hoop and the filter cartridge body can be improved.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This farmland drainage filtration device involves placing a base plate in the farmland and fixing it in place. Then, the locking bolt is loosened to release the locking of the limit rod, and the adjusting head is turned clockwise or counterclockwise with a wrench to rotate the bolt. The rotating bolt, through the connection with the side plate, pushes the filter cylinder body to rise and fall simultaneously until the distance between the bottom of the filter cylinder body and the upper surface of the base plate reaches the required water level in the farmland. Then, the pumping pipe and the baffle with the split hoop installed on the surface are placed inside the filter cylinder body. The filter cylinder body and the split hoop are then fixed together with buckles, fixing plates, and fixing bolts, and sealed with sealing rings. Finally, the pump connected to the pumping pipe is started to pump water. The water in the farmland passes through the bottom hole of the filter cylinder body, is filtered, and enters the interior of the filter cylinder body. The water level in the farmland drops to below the bottom surface of the filter cylinder body. This device facilitates the control of water level and the filtration, pumping, and drainage of farmland water.

[0023] 2. This farmland drainage and filtration device involves placing a base plate in the farmland, immersing it in water until it adheres to the ground, and then passing a fixing nail and a clamp through a groove to drive the fixing nail into the farmland soil. Once the clamp is fully inserted into the groove, it is rotated to lock. At this point, the pumping pipe and filtration mechanism can be connected to the base plate. When the pumping pipe and filter body are pumping water, it can effectively prevent the water flow and the pressure at the bottom of the filter body from directly pumping out the soil or silt from the farmland. This device facilitates the fixing of the pumping pipe and base plate and prevents the bottom silt from entering the filter body. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 A farmland drainage filtration device includes a pumping pipe 1, a bottom support plate 2 below the pumping pipe 1, a filtration mechanism 3 above the bottom support plate 2 for easy filtration off the ground, a baffle 101 fixedly connected to the bottom inlet of the pumping pipe 1, a split hoop 102 clamped and fixedly installed on the outer wall of the pumping pipe 1, a connecting seat 103 installed on the split hoop 102, a buckle plate 104 fixedly connected to the side wall of the split hoop 102, a fixing plate 105 fixedly connected to the top edge of the filter cartridge body 301, a fixing bolt 106 installed on the fixing plate 105, a sealing ring 107 installed on the lower surface of the split hoop 102, the fixing bolt 106 snapped onto the buckle plate 104, the split hoop 102 installed on the upper surface of the filter cartridge body 301, and the sealing ring 107 fixedly connected between the filter cartridge body 301 and the split hoop 102.

[0032] Please see Figure 3-4The filter mechanism 3 includes a filter cartridge body 301, side plates 302, a limiting rod 303, a limiting cylinder 304, a locking bolt 305, a through hole 306, an adjusting head 307, a bolt 308, and a threaded cylinder 309. The filter cartridge body 301 is sleeved on the outside of the water inlet end of the water pumping pipe 1. The two side plates 302 are fixedly connected to the outer surface of the filter cartridge body 301. The limiting rod 303 is fixedly connected to the lower surface of a single side plate 302. The limiting cylinder 304 is fixedly connected to the upper surface of the bottom support plate 2. The locking bolt 305 passes through the filter cartridge body 301. The threaded connection is inserted into the top side wall of the limiting cylinder 304, and the through hole 306 is opened through another side plate 302. The adjusting head 307 is rotatably set in the through hole 306. The bolt 308 is fixedly connected to the bottom of the adjusting head 307. The threaded cylinder 309 is fixedly connected to the upper surface of the bottom support plate 2. The water inlet filter hole of the filter body 301 is opened at the bottom. The limiting rod 303 is slidably inserted into the limiting cylinder 304. The inner end of the locking bolt 305 contacts the side wall of the limiting rod 303. The bolt 308 is threadedly connected to the threaded cylinder 309.

[0033] By setting a filter cartridge body 301, which is positioned above the base plate 2, it facilitates the suction, filtration, and discharge of water from farmland. By setting a side plate 302, a through hole 306, an adjusting screw head 307, a bolt 308, and a threaded cylinder 309, it is possible to control the distance between the filter cartridge body 301 and the base plate 2, thereby controlling the water level after the farmland is pumped out. By setting a side plate 302, a limiting rod 303, a limiting cylinder 304, and a locking bolt 305, when the bolt 308 and threaded cylinder 309 control the lifting and lowering of the filter cartridge body 301, the limiting rod 303 and the limiting cylinder 304 can provide auxiliary limit for the lifting and lowering of the filter cartridge body 301, and the locking bolt 305 can provide auxiliary locking for the height of the filter cartridge body 301.

[0034] Please see Figure 5 The base plate 2 has four fixing blocks 201 around its perimeter. A rotating groove 202 is provided through the fixing block 201. A fixing nail 203 is inserted through the rotating groove 202. A clip head 204 is fixedly connected to the top of the fixing nail 203. The clip head 204 is rotated and locked inside the rotating groove 202.

[0035] By setting a base plate 2, and fixing a limiting cylinder 304 and a threaded cylinder 309 on the base plate 2, the filter cylinder body 301 can be vertically fixed above the base plate 2 for filtration and drainage after the base plate 2 is placed in the farmland. By setting a rotating groove 202, fixing nails 203 and clamps 204, the base plate 2 can be fixed to prevent it from tipping over or shifting during the pumping and drainage process due to excessive silt in the farmland.

[0036] Working principle: When a farmland drainage filtration device is used, in the initial state, the baffle 101 is first set at the bottom of the pumping pipe 1. The split hoop 102 fitted on the pumping pipe 1 is connected to the fixing plate 105 and fixing bolt 106 on the filter body 301 through the buckle plate 104, so as to use the filter body 301 for filtration and drainage. Two side plates 302 are set on the side wall of the filter body 301. The two side plates 302 are respectively set with limit rods 303 and adjusting screws 307 and bolts 308. The limit rods 303 and bolts 308 are respectively connected to the limit cylinders 304 and threaded cylinders 309 on the bottom support plate 2, so as to adjust the height of the filter body 301 from the ground and accurately control the water level. At the same time, fixing nails 203 are connected to the fixing blocks 201 at the four corners of the bottom support plate 2, so as to fix the bottom support plate 2 in the farmland.

[0037] When it is necessary to control the water level and filter and pump out waterlogged farmland, first place the base plate 2 in the farmland and fix it. Then, loosen the locking bolt 305 to release the locking of the limit rod 303 and use a wrench to turn the adjusting head 307 in the forward or reverse direction to rotate the bolt 308. The rotating bolt 308, through the connection with the side plate 302, pushes the filter body 301 to rise and fall simultaneously with the threaded cylinder 309 until the distance between the bottom of the filter body 301 and the upper surface of the base plate 2 reaches the required water level in the farmland. Then, the pumping device with the split hoop 102 installed on the surface can be installed. Pipe 1 and baffle 101 are placed inside the filter cartridge body 301. Then, the filter cartridge body 301 and the split hoop 102 are fixed together using buckle plate 104, fixing plate 105 and fixing bolt 106 and sealed with sealing ring 107. Finally, the water pump connected to the water pumping pipe 1 is started to pump water. The water in the farmland passes through the bottom hole of the filter cartridge body 301, is filtered and enters the interior of the filter cartridge body 301. The water level in the farmland is lowered to below the bottom surface of the filter cartridge body 301. This device is convenient for controlling the water level and filtering, pumping and draining the water in the farmland.

[0038] When it is necessary to fix the pumping pipe 1 and the bottom support plate 2 and prevent the bottom silt from entering the filter body 301, first place the bottom support plate 2 in the farmland and immerse it in the water to fit the ground. Then, pass the fixing nail 203 and the clamp 204 through the groove 202 so that the fixing nail 203 is inserted into the farmland soil. After the clamp 204 is fully inserted into the groove 202, rotate to lock it. At this time, the pumping pipe 1 and the filter mechanism 3 can be connected to the bottom support plate 2. When the pumping pipe 1 and the filter body 301 are pumping water and draining water, it can effectively prevent the water flow and the pressure at the bottom of the filter body 301 from directly pumping out the soil or silt in the farmland. This device is convenient for fixing the pumping pipe 1 and the bottom support plate 2 and preventing the bottom silt from entering the filter body 301.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
