Description

Laydown machine interval, irrigate band casing mechanism

Technical field

The invention belongs to agricultural machinery, relates generally to the interval earthing Working mechanism on a kind of irrigate band laying facility.

Background technology

Drip irrigation is to begin in the last few years the New Water-saving Irrigation applied in the Production of Large Fields operation, and the plurality of advantages such as because its water-saving result is remarkable, water utilization rate is high, and irrigation effect is good is subjected to the welcome of agricultural user deeply.In the irrigate band is laid on the operation process in field, attack in order to prevent wind, the irrigate band of avoiding being laid on the field is blown and is moved, traditional mode is to adopt that manpower is manual to carry out the interval earthing irrigate band is fastened the location, and obviously labour intensity is large, operating efficiency is low, the production cost height is to need to solve the ground problem.In recent years, the irrigate band layer begins to use in agricultural production, its operating efficiency is improved, labour intensity reduces, but due to fault of construction, the casing mechanism on the laydown machine of existing irrigate band is on the irrigate band that uninterruptedly soil layer is covered laying, namely all the irrigate band is buried, do not meet the earth's surface, irrigate band and lay agriculture requirement.

Summary of the invention

The purpose of the invention is exactly the problem that exists for above-mentioned prior art, lay the actual needs of operation in conjunction with the irrigate band, design provides a kind of laydown machine interval, irrigate band casing mechanism of new construction, reaches to meet the purpose that the earth's surface, irrigate band is laid requirement, raising operating efficiency, assurance operation quality, reduced labour intensity and operating cost.

the purpose of the invention is achieved in that laydown machine interval, a kind of irrigate band casing mechanism comprises the earthing wheel that is made of spoke and spacing ring, left in frame, on the right side, symmetrical the hinge installed front bar and rear bar, described front bar and rear bar are parallel to each other, two T shape lower beams are hinged respectively and are arranged on a left side, on the front bar and rear bar on right side, on a left side, between the front bar on right side, the equipped earthing wheel coaxial with T shape lower beam, two guide plates are packed in respectively a left side, on the T shape lower beam bottom on right side, adjacent two spoke left sides on earthing wheel, distinguish two fixed hubs of symmetrical installation separately on the right side, difference plug-in mounting bearing pin in two fixed hubs of the same side, two rotary axle box that are set with torque spring overlap respectively on the bearing pin that fits over both sides, two trailing bars symmetry respectively are packed on two rotary axle box, described torque spring two ends overlap with spoke and trailing bar respectively, be equipped with respectively bearing on the lateral surface of two trailing bars, bearing becomes to contact or disengage cooperation with guide plate, admittedly join trailing bar aperture positive stop on a sidepiece of rotary axle box, this trailing bar aperture positive stop coordinates with becoming to insert with respect to the gap on the fixed hub end of a side.

The invention has realized that irrigate band machinery lays the interval earthing operation in operation, the characteristics of have that structural design is new reasonable, operating efficiency is high, operation quality is good, be conducive to the drip irrigation operation effectiveness, operation is reliable, fault is few.

Embodiment

Below in conjunction with accompanying drawing, the invention embodiment is described in detail.laydown machine interval, a kind of irrigate band casing mechanism comprises the earthing wheel 3 that is made of spoke 4 and spacing ring 5, on frame 1 left side, on the right side, symmetrical the hinge installed front bar 15 and rear bar 2, described front bar 15 is parallel to each other with rear bar 2, two T shape lower beams 6 are hinged respectively and are arranged on a left side, on the front bar 15 and rear bar 2 on right side, on a left side, between the front bar 15 on right side, the equipped earthing wheel 3 coaxial with T shape lower beam 6, two guide plates 7 are packed in respectively a left side, on T shape lower beam 6 bottoms on right side, adjacent two spoke 4 left sides on earthing wheel 3, distinguish two fixed hubs 8 of symmetrical installation separately on the right side, at the interior plug-in mounting bearing pin 14 respectively of two fixed hubs 8 of the same side, two rotary axle box 10 that are set with torque spring 13 overlap respectively on the bearing pin 14 that fits over both sides, two trailing bars 12 symmetry respectively are packed on two rotary axle box 10, described torque spring 13 two ends overlap with spoke 4 and trailing bar 12 respectively, be equipped with respectively bearing 11 on the lateral surface of two trailing bars 12, bearing 11 contacts or disengages cooperation with 7 one-tenth of guide plates, admittedly join trailing bar aperture positive stop 9 on a sidepiece of rotary axle box 10, this trailing bar aperture positive stop 9 coordinates with becoming to insert with respect to the gap on fixed hub 8 ends of a side.

During operation, earthing wheel 3 rotates, and realizes that on frame 1 guide plate 7 is with the ground profiling simultaneously under front bar 15, rear bar 2 and T shape lower beam 6 are controlled; The spoke 4 of earthing wheel 3 drives fixed hub 8, bearing pin 14, rotary axle box 10, trailing bar 12, bearing 11 and torque spring 13, trailing bar aperture positive stop 9 and rotates with earthing wheel 3 in the lump, when the bearing 11 on the trailing bar 12 of left and right side contacts respectively cooperation with the guide plate 7 of left and right side, the trailing bar 12 of left and right side is rotated to earthing wheel 3 is inboard around bearing pin 14, complete the earthing operation of one section drip irrigation pipe; When bearing 11 disengagings contacted cooperation with guide plate 7, under torque spring 13 effects, trailing bar 12 to 3 outsides rotations of earthing wheel, stopped the earthing operation around bearing pin 14.Trailing bar aperture positive stop 9 on rotary axle box 10 coordinates with fixed hub 8, controls and define the aperture of trailing bar 12, guarantees carrying out continuously of earthing operation.
