Abstract

The invention discloses a drag harrow for a small-sized rice transplanter, which comprises a drag harrow body (1); the body (1) is sequentially provided with a first open groove (1a), a first ridging slot (1b), a second open groove (1c), a second ridging slot (1d) and a third open groove (1e) which are arranged in a concave-convex staggered mode, and each ridging slot is of a trapezoidal structure; the convex surface of the first open groove (1a) faces downwards; the downward convex surfaces of the first open groove (1a) and the third open groove (1e) are lower than the downward convex surface of the second open groove (1c). According to the drag harrow, redundant water and soil in the first ridging slot and the second ridging slot can be eliminated timely, so that the ridging molding is facilitated; the forward resistance of the drag harrow is small, so that the labor intensity is alleviated.

Description

The baby transplanter planker

Technical field

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

Background technology

Growth rhythm according to machine transplanting of rice seedling paddy rice, rice transplanting need be satisfied following requirement just can make the rice shoot normal growth, thereby reach the purpose that improves Rice Production efficient and output: 1, the depth of planting can not be crossed dark or shallow excessively, cross and to cause paddy growth slow deeply, cross and shallowly will cause seedling laying and to be lowered into motility rate low, so the depth of planting of rice shoot is advisable to remain on 2～3cm; 2, the field piece water surface can not be too high, and the water surface need remain on about 2～3cm; When 3, adopting machine rice transplantation, in first week of rice transplanting, can not have too much water logging not have rice shoot, but root need water conservation to guarantee growth; 4, the requirement of field piece ground is smooth, and the level land that need harrow a field after the rotary tillage is consistent as far as possible with the depth of planting that guarantees rice shoot.

A kind of small-sized electronic rice transplanter is disclosed among the CN201957435U, comprise planker, mechanism driving arm, rice transplanting arm, frame, move case axle, pull bar, seedling case, frame is fixed on the planker, be provided with direct current generator, accumulator in frame, direct current generator by transmission case drive rice transplanter, move the case axle, the seedlings sending mechanism motion.Direct current generator and decelerator are connected as a single entity.Planker is provided with groove along the rice transplanter direction of advance, and the position of groove is corresponding with the position of rice transplanting arm.The planker bottom is disposed with concavo-convex five staggered trapezoidal ridging grooves, in the process that planker moves ahead, to rice seedling bed ridging moulding.But in the process of ridging, muddy water is difficult to timely discharge, therefore will cause bigger reaction force to planker, thereby influence the effect of ridging moulding, and cause the bigger resistance that moves ahead of planker.

Therefore those skilled in the art are devoted to develop a kind of energy ridging forming rice transplanter planker.

Summary of the invention

Because the above-mentioned defective of prior art, technical problem to be solved by this invention provides the rice transplanter planker of a kind of energy ridging forming.

For achieving the above object, the invention provides a kind of baby transplanter planker, comprise the planker body; Be disposed with the concavo-convex first staggered open channels, the first ridging groove, second open channels, the second ridging groove and the 3rd open channels on the described body, each ridging groove is trapezium structure; The convex surface of described first open channels is downward; 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 further improving the effect of ridging moulding, described first open channels and the 3rd open channels symmetrical configuration; The described first ridging groove and the second ridging groove symmetrical configuration.

For further improving the effect of ridging moulding, the difference in height of the downward convex surface of described first open channels and the 3rd open channels and the downward convex surface of second open channels is 9.5-10.5mm.

The invention has the beneficial effects as follows: the present invention can in time get rid of the first ridging groove and the unnecessary water and soil of the second ridging groove, is convenient to the ridging moulding, also will better keep the movement locus of planker stable, and the planker resistance that moves ahead is little, has reduced labour intensity.

Description of drawings

Fig. 1 is the structural representation of the embodiment of the invention.

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.

Embodiment

The invention will be further described below in conjunction with drawings and Examples:

As depicted in figs. 1 and 2, a kind of baby transplanter planker, comprise planker body 1, be disposed with the concavo-convex 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 on the body 1, each ridging groove is trapezium structure.The 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 convex surface of the first open channels 1a is downward, and 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, and difference in height D is 10mm.

When planker moved ahead work, the unnecessary water and soil of the first ridging groove and the second ridging groove can in time be got rid of from the bottom of second open channels, therefore be convenient to the ridging moulding, and the planker resistance that moves ahead is little, and movement locus is stable.Planker forms the gully at each open channels place after the work of rice seedling bed, form 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 need not creative work and just can design according to the present invention make many modifications and variations.Therefore, all technical staff in the art all should be in the determined protection domain by 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.
