Abstract
The utility model belongs to the field of agricultural seeding machinery, and in particular relates to a seed conveying pipe of a dibbler. The seed conveying pipe comprises a seed inlet and a seed outlet, wherein the lower segment of a seed conveying pipe body bends in an arc shape towards one side of the advance direction of the dibbler, and the opening area of the seed inlet is more than that of the seed outlet. The seed conveying pipe has the advantages of good internal characteristics and external characteristics, can reduce the resistance in the advance direction of the dibbler at the same time, and is worthy to be popularized and applied.
Description
(1) technical field
The utility model belongs to agricultural seeder machinery field, particularly a kind of hill-drop planter grain tube.
(2) background technology
The rigidity grain tube that on the agricultural machinery hill-drop planter, uses, the upper end links to each other with frame during installation, hypomere is installed furrower, it during bunch planting the cavitation that keeps seed in the trench, the collision that the requirement seed that the branch cave falls from seeding unit is subjected in grain tube is disturbed little, more can not produce the reflectivity spring, grain tube generally all adopts and erects straight pipe for this reason, or erect big young taper flat tube down suitable for reading, though this grain tube internal characteristic is better, external characteristics is relatively poor, easily stop up during such as bunch planting and hang weeds at the grain tube hypomere, foreign material such as crushing straw, influence soil and return and cover seed, can not operation so that get congestion, also increased mechanical resistance simultaneously.Also have and adopt the tiltedly upright tubular grain tube that uses on the drilling machine, or epimere erects, the hypomere arc is (hill-drop planter direction of advance) crooked tubular grain tube forward, has improved external characteristics, but internal characteristic variation again.
(3) utility model content
The purpose of this utility model is to provide a kind of hill-drop planter grain tube, internal characteristic, external characteristics can both satisfy the needs of bunch planting process, have both guaranteed the cavitation that seed is good, have also avoided in the bunch planting process weeds to block up, influence soil and return lid, the problem that hill-drop planter can not operation.
The technical solution adopted in the utility model is as follows:
A kind of hill-drop planter grain tube comprises seed inlet and goes out kind of a mouth that grain tube body hypomere is to hill-drop planter direction of advance one side arc-shaped bend, and described seed inlet aperture area is greater than going out kind of a mouth.
Further, design grain tube body is vertical to a side epimere of hill-drop planter direction of advance, and hypomere is to hill-drop planter direction of advance arc-shaped bend, and its lap of body is to be not more than curvature to hill-drop planter direction of advance face to the bending of seed inlet central shaft.
Above-mentioned grain tube from the big seed inlet of opening be gradual change dwindle carry out the transition to opening little go out kind of a mouth.The grain tube body is to the bending of hill-drop planter direction of advance, in the soil and foreign material such as ground weeds crushing straw as hanging on the grain tube, be subjected to the effect of direction of advance power, can be along sliding rising the on the grain tube camber line outer wall, swing to a side until disequilibrium, solved weeds and blocked up, influenced soil and return the problem that lid, hill-drop planter can not operations.And the seed inlet aperture area is greater than going out kind of a mouth, in being convenient to concentrate on seed more among a small circle, so the seed cavitation is all right naturally.Because the grain tube body is to hill-drop planter direction of advance arc-shaped bend, and the radius of curvature of this face is greater than the radius of curvature of other faces, so straight-through up and down area is bigger in the tube, possesses the condition that the seed straight line falls, again because of barrel and seeds fall angular separation are less all around, so perisporium can not produce the reflectivity spring to the whereabouts seed.
Concrete, it is circular or oblate that described grain tube seed inlet can be designed to rectangle.Going out kind of mouth is good with oblateness.
Because hill-drop planter advances in the process, grain tube is bigger at the suffered resistance of direction of advance, the described grain tube of optimal design goes out kind of mouth in the size of the hill-drop planter direction of advance size greater than vertical hill-drop planter direction of advance, increased the force intensity that is subjected to of this direction grain tube on the one hand, the feasible blocking surface to soil that reduces of lateral dimension diminishes on the other hand, so facility tractive force is also little.
The utility model has following advantage with respect to prior art:
The grain tube of the utility model design has good internal characteristic and external characteristics, can also reduce the resistance of hill-drop planter direction of advance simultaneously, has the excellent popularization using value.
(4) description of drawings
Fig. 1 is the front view of grain tube among the embodiment 1;
Fig. 2 is the left view of grain tube among Fig. 1;
Fig. 3 is the vertical view of grain tube among Fig. 1;
Fig. 4 (a) and (b), (c), (d) go out the schematic diagram of kind of mouth for grain tube.
(5) embodiment:
Below with specific embodiment the technical solution of the utility model is described, but protection domain of the present utility model is not limited thereto:
In conjunction with Fig. 1-4, hill-drop planter grain tube 1 comprises that rectangle seed inlet 2 and oblateness go out kind of mouth 3, and described seed inlet aperture area is greater than going out kind of a mouth, goes out kind of mouth 3 in the size of the hill-drop planter direction of advance size greater than vertical hill-drop planter direction of advance; The grain tube body is vertical to a side epimere of hill-drop planter direction of advance among Fig. 1, and hypomere is to hill-drop planter direction of advance arc-shaped bend, its lap of body with the curvature that is not more than hill-drop planter direction of advance face to the bending of seed inlet central shaft.From Fig. 2, grain tube left and right sides symmetry narrows down downwards with camber line or straight line than small curve, and final end face is transited into oblateness shown in Figure 3.Wherein go out kind of mouth 3 and also can be designed to shape in the (a) and (b), (c), (d) among Fig. 4.
Claims (4)
1. a hill-drop planter grain tube comprises seed inlet and goes out kind of a mouth, and it is characterized in that grain tube body hypomere to hill-drop planter direction of advance one side arc-shaped bend, described seed inlet aperture area is greater than going out kind of a mouth.
2. hill-drop planter grain tube as claimed in claim 1, it is characterized in that the grain tube body is vertical to a side epimere of hill-drop planter direction of advance, hypomere is to hill-drop planter direction of advance arc-shaped bend, and its lap of body is to be not more than curvature to hill-drop planter direction of advance face to the bending of seed inlet central shaft.
3. hill-drop planter grain tube as claimed in claim 1 or 2 is characterized in that described grain tube goes out kind of mouth in the size of the hill-drop planter direction of advance size greater than vertical hill-drop planter direction of advance.
4. hill-drop planter grain tube as claimed in claim 3 is characterized in that described grain tube seed inlet is that rectangle is circular or oblate.
