Abstract

The invention discloses a small rice transplanter carriage, comprising a carriage body (1). A first ditching groove (1a), a first ridging groove (1b), a second ditching groove (1c), a second ridging groove (1d) and a third ditching groove (1e), which are distributed in a concave-convex staggered way, are orderly formed in the body (1); each ridging groove is trapezoidal; the convex surface of the first ditching groove (1a) is downward; the first ditching groove (1a) and the third ditching groove (1e) are structurally symmetrical to each other; the first ridging groove (1b) and the second ridging groove (1d) are structurally symmetrical to each other. The small rice transplanter carriage has a good ridging forming effect, causes small waves when walking, and can relieve accumulation of soil beside the carriage so as to avoid impact and damage on rice seedlings planted on one side of a rice transplanter.

Description

Small rice transplanter carriage

Technical field

The present invention relates to a kind of agricultural machinery, particularly relate to a kind of planker of rice transplanter.

Background technology

According to the growth rhythm of transplanting paddy rice, rice transplanting need meet following requirement just can make rice shoot normal growth, thus reach the object improving Rice Production efficiency and output: 1, the depth of planting can not be crossed dark or excessively shallow, cross and deeply paddy growth will be caused slow, cross and shallowly will cause seedling laying and to be lowered into motility rate low, therefore the depth of planting of rice shoot is advisable to remain on 2 ~ 3cm; 2, the field water surface can not be too high, and the water surface need remain on about 2 ~ 3cm; When 3, adopting machine rice transplantation, too much water logging can not be had not have rice shoot in first week of rice transplanting, but root need water conservation to ensure growth; 4, field ground requires smooth, needs to harrow a field level land to ensure the depth of planting of rice shoot as far as possible unanimously after rotary tillage.

A kind of small-sized electric rice transplanter is disclosed in CN201957435U, comprise planker, mechanism driving arm, transplanting arm, frame, move case axle, pull bar, seedling case, frame is fixed on planker, frame is provided with direct current generator, accumulator, direct current generator drives rice transplanter by transmission case, moves case axle, seedlings sending mechanism motion.Direct current generator and decelerator are connected as a single entity.Planker is provided with groove along rice transplanter direction of advance, and the position of groove is corresponding with the position of transplanting arm.In this structure, concavo-convex five staggered trapezoidal ridging grooves are disposed with bottom planker, but because the trapezoidal drift angle of each ridging groove or base angle angle arrange unreasonable, therefore the shaping difference of ridging, and during rice transplanter walking work, to larger wave be produced, and earth is piled up to planker side, thus the rice shoot that impact injury rice transplanter side has been plugged.

Therefore those skilled in the art be devoted to develop a kind of can ridging forming, rice transplanter planker that walking wave is little.

Summary of the invention

Because the above-mentioned defect of prior art, technical problem to be solved by this invention be to provide a kind of can ridging forming, rice transplanter planker that walking wave is little.

For achieving the above object, the invention provides a kind of small rice transplanter carriage, comprise planker body; Described body is disposed with concavo-convex the first staggered open channels, the first ridging groove, the second open channels, the second ridging groove and the 3rd open channels, each ridging groove is trapezium structure; The convex surface of described first open channels is downward; Described first open channels and the 3rd open channels symmetrical configuration; Described first ridging groove and the second ridging groove symmetrical configuration.

For ease of the first ridging groove and the unnecessary water and soil of the second ridging groove being got rid of in time, be convenient to ridging, the downward convex surface of described first open channels and the 3rd open channels is lower than the downward convex surface of described second open channels.

For when reducing planker walking, institute produces larger wave, and a large amount of earth is piled up outside planker, the limit, the left and right sides of the outside trapezoidal side formation planker of described first open channels and the 3rd open channels.

Shaping for being convenient to ridging further, and reducing walking wave, extremely interior the first formed trapezoidal base angle, the second trapezoidal base angle, the 3rd trapezoidal base angle and the 4th trapezoidal base angle are followed successively by 104 °, 108 °, 108 ° and 124 ° by outside planker for described first open channels and the first ridging groove.

The invention has the beneficial effects as follows: ridging good forming effect of the present invention, the wave produced during planker walking is little, and can reduce the accumulation of earth to planker side, thus avoids the rice shoot that impact injury rice transplanter side has been plugged.

Embodiment

Below in conjunction with drawings and Examples, the invention will be further described:

As shown in Figure 1 to Figure 3, a kind of small rice transplanter carriage, comprises planker body 1, body 1 is disposed with concavo-convex the first staggered open channels 1a, the first ridging groove 1b, the second open channels 1c, the second ridging groove 1d and the 3rd open channels 1e.Each ridging groove is trapezium structure, and the convex surface of the first open channels 1a is downward.First open channels 1a and the 3rd open channels 1e symmetrical configuration, the first ridging groove 1b and the second ridging groove 1d symmetrical configuration.

The downward convex surface of the first open channels 1a and the 3rd open channels 1e is lower than the downward convex surface of the second open channels 1c, namely there is difference in height d in the downward convex surface of the first open channels 1a and the 3rd open channels 1e and the downward convex surface of the second open channels 1c, therefore when ridging is shaping, water and soil unnecessary for first ridging groove 1b and the second ridging groove 1d can be discharged in time the below of the second open channels 1c, thus it is shaping to be beneficial to ridging.

The outside trapezoidal side of the first open channels 1a and the 3rd open channels 1e forms the limit, the left and right sides of planker, thus the wave that when can reduce planker walking, both sides produce, and be convenient to planker manufacture processing, reduce production cost.

By outside planker, extremely interior the formed trapezoidal base angle θ 2 of the first trapezoidal base angle θ 1, second, the 3rd trapezoidal base angle θ 3 and the 4th trapezoidal base angle θ 4 are followed successively by 104 °, 108 °, 108 ° and 124 ° to first open channels 1a and the first ridging groove 1b.

Due to the unique design to each trapezoidal bottom angular dimensions, the wave therefore produced during planker walking is little, and can reduce the accumulation of earth to planker side, thus avoids the rice shoot that impact injury rice transplanter side has been plugged; Meanwhile, during planker walking ridging, be also convenient to pack up earth, and the middle part of unnecessary muddy water to planker is filled, to reduce walking resistance.Planker, after the work of rice seedling bed, in formation gully, each open channels place, forms field at each ridging groove place.

More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
