Description

Technical Field

[0001] This utility model relates to a box-type farmland sluice gate in the field of farmland irrigation and drainage. Background Technology

[0002] Farmland irrigation and drainage are divided into surface irrigation and deep irrigation: Surface irrigation drains the water from the field when rice seedlings are transplanted, and then refills the field after the seedlings have taken root; this is surface irrigation. Deep irrigation drains the water from the topsoil by digging ditches before rice harvesting, and then refills the ditches before the soil is leveled the following year; this is deep irrigation. In plains farmland, pump irrigation is used, typically by burying water pipes under concrete field ridges, with one end in the field and the other in the irrigation ditch. Because the pipes are slightly higher than the bottom of the irrigation ditch but slightly lower than the topsoil, deep irrigation and drainage can be implemented: when drainage is needed, water from the ditch is first drained into the river, and then water from the field ditches is drained into the ditch and flows into the river; when irrigation is needed, river water is pumped into the ditch, raising the water level and then irrigating the field ditches. Before rice transplanting, the topsoil must be leveled. This buries the irrigation ditches and pipes in the field. Therefore, a 90-degree bend must be fitted over the existing pipes, with the other end of the bend facing upwards and level with the field surface. This blocks the topsoil, ensuring unobstructed water flow for surface irrigation. When water storage is needed, a vertical pipe is inserted into the bend. Because this vertical pipe is higher than the paddy field water level, the water is trapped around it and cannot flow out, allowing only irrigation water to enter the vertical pipe and not the paddy field. When surface drainage is required, the irrigation water is drained into a river, and the vertical pipe is removed, allowing surface water to flow down from the top of the bend into the irrigation canal and finally into the river. This irrigation and drainage system is inconvenient for regulating farmland water levels and is cumbersome to operate, especially during rainy days when the water level rises continuously. The vertical pipe must be pulled out or inserted periodically to regulate the water level. Currently, the gates and sleeves of various sluice gates on the market and in patent documents are tightly fitted together. If they are fitted with deep water pipes, they will be buried by the soil of the cultivated layer and surface irrigation and drainage will be impossible. Such sluice gates can only be fitted with surface water pipes. Summary of the Invention

[0003] This utility model provides a box-type farmland sluice gate, characterized in that it consists of a box body, a mudguard, and a water-blocking plate; the box body is square, with a sleeve at the bottom rear and grooves on the front sides and bottom; the mudguard is square, with a height approximately equal to the depth of the cultivated layer and approximately half the height of the box body, and has grooves on the back of its two sides, with the groove openings facing inwards and side plates outside the groove bottoms; the grooves, side plates, and groove plates extend upwards, slightly higher than the box body; the side plates have symmetrical perforations in the middle and lower top, and are equipped with insert plates; the water-blocking plate is the same height as the mudguard, with pull rods on the upper left and right sides, the pull rods having vertically arranged water level holes and being equipped with plugs, and handles at the top, the handles being slightly higher than the grooves; the side plates of the mudguard are fitted into the grooves, and the sides of the water-blocking plate and the pull rods are fitted into the grooves. This sluice gate, when fitted with a deep water pipe, can perform surface irrigation and drainage and deep irrigation of farmland, and facilitates the regulation of farmland water levels.

Figure 3 For mudguards, Figure 4 The diagram shows the following components: 1 is the housing, 1.1 is the sleeve, 1.2 is the groove, 2 is the mudguard, 2.1 is the sleeve groove, 2.2 is the side plate, 2.3 is the groove plate, 2.4 is the plate hole, 3 is the water baffle, 3.1 is the pull rod, 3.2 is the water level hole, 3.3 is the handle, 4 is the insert plate, 5 is the plug, and 6 is the water pipe. Detailed Implementation

[0005] As shown in the figure, this utility model is mainly composed of a box body 1, a mudguard 2, and a water-blocking plate 3; the box body 1 is square, with a sleeve 1.1 at the bottom rear, and grooves 1.2 on the front sides and bottom; the mudguard 2 is square, with a height approximately equal to the depth of the tillage layer and approximately half the height of the box body 1, and has a sleeve groove 2.1 on the back of its two sides, with the groove opening facing inward, and a side plate 2.2 outside the bottom of the groove; the sleeve groove 2.1, the side plate 2.2, and the groove plate 2.3 extend upward, slightly higher than the box body 1; The side plate 2.2 has symmetrical holes 2.4 in the middle and lower top, and is equipped with insert plates 4. The height of the water baffle 3 is the same as that of the mud baffle 2. There are pull rods 3.1 on the upper left and right sides. The pull rods 3.1 have vertically arranged water level holes 3.2 and are equipped with plugs 5. The top has a handle 3.3, which is slightly higher than the groove 2.1. The side plate 2.2 of the mud baffle 2 is fitted into the groove 1.2, and the two sides of the water baffle 3 and the pull rods 3.1 are fitted into the groove 2.1. When this sluice gate is fitted with the deep water pipe 6, it can perform surface irrigation and deep irrigation and drainage of farmland, and facilitate the regulation of farmland water level. Since the mudguard 2 and the sleeve 1.1 are located on the front and rear sides of the box body 1 respectively, when surface irrigation and drainage are required, the mudguard 2 and the water-blocking plate 3 can be pressed down simultaneously to block the soil in the cultivated layer. The water on the field surface can flow down from above the mudguard 2 and the water-blocking plate 3 into the box body 1, and then be discharged through the water pipe 6. At the same time, the ditch water can also be injected into the field through the water pipe 6. When water storage is required, the mudguard 2 is kept stationary at the bottom, and the water-blocking plate 3 is raised to the required water level. Excess water will flow into the box body 1 from above the water-blocking plate 3, and then be discharged through the water pipe 6. When deep drainage is required, the mudguard 2 and the water-blocking plate 3 can be pulled up above the cultivated layer at the same time to introduce the ditch water in the field into the box body 1, and then be discharged through the water pipe 6. Insert plate 4 is inserted into plate hole 2.4, which can be used to manipulate mudguard 2 to move up and down, and can be locked above groove 1.1 to fix the height of mudguard 2; plug 5 is inserted into positioning hole 3.2 and locked above sleeve groove 2.1 to fix the height of water baffle 3.
