Abstract
The invention relates to the technical field of agricultural equipment, and discloses an agricultural drip irrigation control device. The agricultural drip irrigation control device comprises an outer shell, an upper gland and a lower gland. The upper gland and the lower gland are sequentially arranged in the outer shell in a sleeved mode from top to bottom, and a water seepage cavity is formed between the upper gland and the lower gland. A water inlet is formed in the upper gland and connected with a water inlet pipe, a water outlet is formed in the lower gland and connected with a water outlet pipe, and an elastic cap is clamped between the upper gland and the lower gland and blocks the water inlet and the water outlet. A slope is arranged at the upper end of the upper gland, a wedge block is arranged on the slope in a matched mode, a limiting rod arranged on the inner wall of the outer shell abuts against the upper portion of the wedge block, a compression spring is connected between one end of the wedge block and the inner wall of the outer shell, and the other end of the wedge block abuts against a screw in threaded connection with the outer shell. According to the scheme, adjustment of the water drip amount in the drip irrigation process is facilitated, and meanwhile the adjustment mode is convenient to implement; drip irrigation is carried out through the gravity of water without dependence on tap water, and therefore environmental adaptability is high.
Description
Technical field
The present invention relates to agricultural equipment technical field.
Background technology
Drip irrigation (dripirrigation) utilizes plastic conduit that water is about aperture on 10mm hollow billet or water dropper by diameter to deliver to crop root and carry out localized irrigation.It is the most effective a kind of Water Saving Irrigation Mode of current drought and water-scarce area, and the availability of water can reach 95%.Drip irrigation is comparatively sprayed and is had higher water-saving and yield-increasing effect, in conjunction with fertilising, can improve fertilizer efficiency more than one times simultaneously.Be applicable to fruit tree, vegetables, economic crops and green house to irrigate, also can be used for field crop irrigation in the place of drought and water shortage.Its weak point is the easy fouling of water dropper and blocking, therefore tackles water source and carries out strict filtration treatment.For larger plant, and the position of comparatively concentrating is carried out a kind of convenient drip irrigation of adjustment one by one amount of drip irrigation needs, and regulate the control device of the amount of dripping whenever and wherever possible; Simultaneously when not having water works, carry out drip irrigation by the natural water pressures such as bottled water (gravity), because pressure is too small, existing equipment cannot normally work.
Summary of the invention
The invention is intended to provide a kind of convenient agricultural drop irrigation control device regulating the amount of dripping.
Agricultural drop irrigation control device in this programme, comprise shell, upper press cover, lower cover is provided with successively from top to bottom in shell, form infiltration chamber between upper press cover and lower cover, upper press cover has water inlet, the external water inlet pipe of water inlet, lower cover has delivery port, delivery port picks out water pipe, clamps flexible cap between upper press cover and lower cover, and this spring caps shutoff is on water inlet and delivery port; Described upper press cover upper end is provided with inclined-plane, inclined-plane is combined with wedge, the gag lever post be arranged on above wedge on outer casing inner wall pushes against, and is connected with stage clip between one end of this wedge and outer casing inner wall, the wedge other end be threaded in shell screwing and offset.Screw
Beneficial effect: current pass into from water inlet pipe, the water inlet be provided with of upper press cover is arrived by Action of Gravity Field, due to upper press cover and lower cover push against by spring caps, so water inlet and delivery port only have six milling gaps to be closed even completely, make the amount of dripping at least or be zero; By rotary screw, screw swivel feeding promotes wedge and moves, and wedge promotes upper press cover and moves down, and spring caps is shunk, thus reduces the opening clearance of water inlet and delivery port, reduces the amount of dripping; Reversely rotate screw, upper press cover moves up under the elastic force of spring caps, thus increases the opening clearance of water inlet and delivery port, increases the amount of dripping; Adopt such scheme, facilitate the adjustment carrying out the amount of dripping in drip irrigation process, regulative mode is convenient with operation simultaneously, and the gravity utilizing water spontaneous carries out drip irrigation, and eliminate the dependence to running water (press water), it is strong that environment is suitable for ability.
Further, described spring caps comprises cap, lower cap and holddown spring, and upper cap and lower cap sleeve connect, and holddown spring is installed in cap and lower cap; Controlled the folding of upper cap and lower cap by the elastic force of holddown spring, structure is simple, is easy to install.
Further, outside described lower cover infiltration chamber and be connected with support spring between outer casing inner wall; Support spring can play cushioning effect, avoids cap and lower cap excessively to compress damaged.
Further, described upper press cover and lower cover are provided with sealant; Increase upper press cover and outer casing inner wall, sealing between lower cover and outer casing inner wall.
Further, the drive end of described screw is provided with the striped nut being convenient to hand adjustment, and striped nut can increase it in the frictional force of finger, is convenient to screw regulate.
Accompanying drawing explanation
Fig. 1 is the structural representation of agricultural drop irrigation control device embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: shell 1, gag lever post 11, upper press cover 2, water inlet pipe 21, lower cover 3, outlet pipe 31, support spring 32, upper cap 4, lower cap 41, holddown spring 42, screw 5, wedge 51, stage clip 52.
Embodiment is substantially as shown in Figure 1:
Agricultural drop irrigation control device in this programme, comprise shell 1, upper press cover 2 and lower cover 3, upper press cover 2 and lower cover 3 from top to bottom successively inner sleeve in shell 1, form infiltration chamber between upper press cover 2 and lower cover 3, upper press cover 2 has water inlet, and water inlet is connected with water inlet pipe 21, lower cover 3 has delivery port, delivery port is connected with outlet pipe 31, clamps flexible cap between upper press cover 2 and lower cover 3, and this spring caps shutoff is on water inlet and delivery port.
Upper press cover 2 upper end is provided with inclined-plane, inclined-plane is combined with wedge 51, the gag lever post 11 be welded on above wedge 51 on shell 1 inwall pushes against, and be connected with stage clip 52 between one end of this wedge 51 and shell 1 inwall, wedge 51 other end pushes against the screw 5 be threaded on shell 1.Spring caps comprises cap 4, lower cap 41 and holddown spring 42, and upper cap 4 and lower cap 41 are socketed, and holddown spring 42 is installed in cap 4 and lower cap 41; Controlled the folding of upper cap 4 and lower cap 41 by the elastic force of holddown spring 42, structure is simple, is easy to install.
